2021 ACIP adult schedule released
The Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention has updated its recommended immunization schedule for adults for 2021.
A summary of the annual update was published online Feb. 11 in the CDC’s Morbidity and Mortality Weekly Report and is available in Annals of Internal Medicine and on the CDC website.
It features a special section on vaccination during the pandemic as well as interim recommendations on administering the Pfizer-BioNtech and Moderna COVID-19 vaccines.
The authors, led by Mark S. Freedman, DVM, MPH, DACVPM, of the CDC’s National Center for Immunization and Respiratory Diseases, in Atlanta, note that this year’s recommendations for adults – persons aged 19 years and older – are largely the same as last year’s. “There have been very few changes,” Dr. Freedman said in an interview. “Changes to the schedule tables and notes were made to harmonize to the greatest extent possible the adult and child/adolescent schedules.”
Changes in the schedule include new or updated ACIP recommendations for influenza, hepatitis A, hepatitis B (Hep B), and human papillomavirus (HPV) as well as for meningococcal serogroups A, C, W, and Y (MenACYW) vaccines, meningococcal B (MenB) vaccines, and the zoster vaccine.
Vaccine-specific changes
Influenza
The schedule highlights updates to the composition of several influenza vaccines, which apply to components in both trivalent and quadrivalent formulations.
The cover page abbreviation for live attenuated influenza vaccine (LAIV) was changed to LAIV4. The abbreviation for live recombinant influenza vaccine (RIV) was changed to RIV4.
For individuals with a history of egg allergy who experience reactions other than hives, the following procedural warning has been added: “If using an influenza vaccine other than RIV4 or ccIIV4, administer in medical setting under supervision of health care provider who can recognize and manage severe allergic reactions.”
Zoster
The zoster vaccine live (Zostavax) has been removed from the schedule because it is no longer available in the United States. The recombinant zoster vaccine Shingrix remains available as a 2-dose regimen for adults aged 50 years or older.
HPV
As in previous years, HPV vaccination is routinely recommended for persons aged 11-12 years, with catch-up vaccination for those aged 26 or younger. Catch-up vaccination can be considered with shared decision making for those aged 27 through 45. In this year’s schedule, in the pregnancy column, the color pink, which formerly indicated “delay until after pregnancy,” has been replaced with red and an asterisk, indicating “vaccinate after pregnancy.”
HepB
ACIP continues to recommend vaccination of adults at risk for HepB; however, the text overlay has been changed to read, “2, 3, or 4 doses, depending on vaccine or condition.” Additionally, HepB vaccination is now routinely recommended for adults younger than 60 years with diabetes. For those with diabetes who are older than 60, shared decision making is recommended.
Meningococcal vaccine
ACIP continues to recommend routine vaccination with a quadrivalent meningococcal conjugate vaccine (MenACWY) for persons at increased risk for meningococcal disease caused by serogroups A, C, W, or Y. The MenQuadfi (MenACWY-TT) vaccine, which was first licensed in 2020, has been added to all relevant sections of MenACWY vaccines. For MenACWY booster doses, new text addresses special situations, including outbreaks.
Improvements have been made to text and layout, Dr. Freedman said. An example is the minimizing of specialized text. Other changes were made to ensure more consistent text structure and language. Various fine-tunings of color and positioning were made to the cover page and tables, and the wording of the notes sections was improved.
Vaccination in the pandemic
The updated schedule outlines guidance on the use of COVID-19 vaccines approved by the Food and Drug Administration under emergency use authorization, with interim recommendations for the Pfizer-BioNTech COVID-19 vaccine for people aged 16 and older and the Moderna COVID-19 vaccine for people aged 18 and older.
The authors stress the importance of receiving the recommended routine and catch-up immunizations notwithstanding widespread anxiety about visiting medical offices. Last spring, the CDC reported a dramatic drop in child vaccinations after the declaration of the national emergency in mid-March, a drop attributed to fear of COVID-19 exposure.
“ACIP continued to meet and make recommendations during the pandemic,” Dr. Freedman said. “Our recommendation remains that despite challenges caused by the COVID-19 pandemic, adults and their healthcare providers should follow the recommended vaccine schedule to protect against serious and sometimes deadly diseases.”
Regular vaccines can be safely administered even as COVID-19 retains its grasp on the United States. “Healthcare providers should follow the CDC’s interim guidance for the safe delivery of vaccines during the pandemic, which includes the use of personal protective equipment and physical distancing,” Dr. Freedman said.
Dr. Freedman has disclosed no relevant financial relationships. Coauthor Henry Bernstein, DO, is the editor of the Current Opinion in Pediatrics Office Pediatrics Series, is a Harvard School of Public Health faculty member, and is a member of the data safety and monitoring board for a Takeda study on intrathecal enzymes for Hunter and San Filippo syndromes. Coauthor Kevin Ault, MD, has served on the data safety and monitoring committee for ACI Clinical.

Are diagnosticians chasing COVID-linked zebras and missing horses?
The emergence of multiple inflammatory syndrome in children (MIS-C) in association with COVID-19 may be complicating the investigation and diagnosis of more common viral and bacterial infections, potentially delaying treatment and prolonging hospital stays.
Two recent articles published online in Hospital Pediatrics provide evidence of this phenomenon. The articles outlined case studies of children who underwent extensive investigation for MIS-C when in fact they had less severe and more common infections. MIS-C is a severe but rare syndrome that involves systemic hyperinflammation with fever and multisystem organ dysfunction similar to that of Kawasaki disease (KD).
In one of the articles, Matthew Molloy, MD, MPH, of the division of pediatric hospital medicine at Cincinnati Children’s Hospital Medical Center, and colleagues aptly asked: “What are we missing in our search for MIS-C?”
E. coli, not SARS-CoV-2
That question arose from a case involving a 3-year-old boy who had a 6-day history of fever and fatigue. Three days earlier, he had tested negative for strep antigen and COVID-19. He had a persistent, high fever, reduced appetite, and reduced urine output and was taken to the ED. On physical examination, there was no rash, skin peeling, redness of the eye or oral mucosa, congestion, rhinorrhea, cough, shortness of breath, chest pain, abdominal pain, nausea, vomiting, or diarrhea.
Urinalysis results and exam findings were suspicious for pyelonephritis. Other findings from an extensive laboratory workup raised the alarm that the boy was suffering from MIS-C as opposed to incomplete KD. After admission to hospital medicine, the cardiology, rheumatology, and infectious disease teams were called in to consult.
Repeat labs were planned for the following day before initiating therapy. On day 2, the child’s urine culture was positive for gram-negative rods, later identified as Escherichia coli. The boy was started on ceftriaxone. Left renal scarring was apparent on ultrasound. The patient’s condition resolved after 36 hours, and he was discharged home with antibiotics.
‘Diagnosis derailed’
Calling this a case of “diagnosis derailed,” the authors noted that, in the pre-COVID era, this child’s signs and symptoms would likely have triggered a more targeted and less costly evaluation for more common infectious and noninfectious causes, including pyelonephritis, absent any physical exam findings consistent with KD.
“However, the patient presented in the midst of the COVID-19 pandemic with growing awareness of a new clinical entity,” Dr. Molloy and colleagues wrote. “Anchored to the patient’s persistent fever, the medical team initiated an extensive, costly, and ultimately unnecessary workup to avoid missing the diagnosis of MIS-C; a not yet well-described diagnosis with potentially severe morbidity.”
Confirmation bias and diagnostic momentum likely contributed to the early focus on MIS-C rather than more common alternatives, the authors acknowledged. The addition of mildly abnormal laboratory data not typically obtained in the evaluation of fever led the team astray. “The diagnosis and definitive treatment may have been made earlier had the focus on concern for MIS-C not been present,” Dr. Molloy said in an interview.
Keeping value in care
The authors recognized that their initial approach to evaluating for MIS-C provided low-value care. “In our desire to not ‘miss’ MIS-C, we were performing costly evaluations that at times produced mildly abnormal, nonspecific results,” they wrote. That triggered a cascade of specialty consultations, follow-up testing, and an unwarranted diagnostic preoccupation with MIS-C.
Determining the extra price tag for the child’s workup would be complex and difficult because there is a difference in the cost to the hospital and the cost to the family, Dr. Molloy said. “However, there are potential cost savings that would be related to making a correct diagnosis in a timely manner in terms of preventing downstream effects from delayed diagnoses.”
Even as clinicians struggle with the challenging SARS-CoV-2 learning curve, Dr. Molloy and associates urged them to continue to strive for high-value care, with an unwavering focus on using only necessary resources, a stewardship the pandemic has shown to be critical.
“The COVID-19 pandemic has been an incredibly stressful time for physicians and for families,” Dr. Molloy said. “COVID-19 and related conditions like MIS-C are new, and we are learning more and more about them every week. These diagnoses are understandably on the minds of physicians and families when children present with fever.” Notwithstanding, the boy’s case underscores the need for clinicians to consider alternate diagnoses and the value of the care provided.
Impact of bias
Dr. Molloy’s group brings home the cognitive biases practitioners often suffer from, including anchoring and confirmation bias and diagnostic momentum, according to J. Howard Smart, MD, chief of pediatrics at Sharp Mary Birch Hospital for Women and Newborns, San Diego, and an assistant clinical professor of pediatrics at University of California, San Diego.
“But it is one thing to recognize these in retrospect and quite another to consider whether they may be happening to you yourself in real time,” he said in an interview. “It is almost as if we need to have a ‘time out,’ where we stop and ask ourselves whether there is something else that could be explaining our patient’s presentation, something that would be more common and more likely to be occurring.”
According to Dr. Smart, who was not involved in Dr. Molloy’s study, the team’s premature diagnostic focus on MIS-C was almost the inverse of what typically happens with KD. “It is usually the case that Kawasaki disease does not enter the differential diagnosis until late in the course of the fever, typically on day 5 or later, when it may have been better to think of it earlier,” he said.
In the second article, Andrea Dean, MD, of the department of pediatrics at Baylor College of Medicine and Texas Children’s Hospital, both in Houston, and colleagues outlined the cases of five patients aged 8-17 years who were hospitalized in May 2020 for suspected MIS-C. They exhibited inflammatory and other concerning indicators but were eventually discharged with a diagnosis of murine typhus.
This flea-borne infection, most commonly reported in the United States in the southeastern Gulf Coast region, Hawaii, and California, is often associated with a triad of fever, rash, and headache.
Cases have been rising in southern Texas, and Dr. Dean and colleagues postulated that school closures and social distancing may have increased exposure as a result of children spending more time outdoors or with pets. “Alternatively, parental concern for SARS-CoV-2 infection could mean children with symptoms are presenting to care and being referred or admitted to the hospital more frequently due to provider concern for MIS-C,” they wrote.
Cardiac involvement
The most concerning of the five cases in terms of possible MIS-C, Dr. Dean said in an interview, was that of a 12-year-old boy who had fever for 6 days in association with headache, eczematous rash, dry lips, and conjunctivitis. Laboratory tests showed a mildly elevated C-reactive protein level, hyponatremia, and thrombocytopenia, as well as sterile pyuria and mildly elevated prothrombin time. He was treated empirically with doxycycline, and his fever resolved over the next 24 hours.
An echocardiogram at initial evaluation, however, revealed mild dilation of the left anterior descending and right coronary arteries, which led to the administration of intravenous immunoglobulin and aspirin for atypical KD, in contrast to MIS-C. The authors postulated that mild cardiac involvement in disorders other than MIS-C and KD may be underrecognized.
The lesson from these cases, Dr. Dean and associates concluded, is that hospitalists must maintain a wide differential diagnosis when assessing a child with prolonged fever and evidence of systemic inflammation. The CDC stipulates that a diagnosis of MIS-C requires the absence of a plausible alternative diagnosis.
In addition to common viral, bacterial, and noninfectious disorders, a range of regional endemic rickettsial and parasitic infections must be considered as alternative diagnoses to MIS-C. “Many of these diseases cannot be reliably differentiated from MIS-C on presentation, and as community exposure to SARS-CoV-2 grows, hospitalists should be prepared to admit febrile children with evidence of systemic inflammation for brief observation periods to evaluate for MIS-C,” Dr. Dean’s group wrote. In this context, however, empiric treatment for common or even uncommon infectious diseases may avoid overdiagnosis and overtreatment of MIS-C as well as improve patient outcomes.
“We do have specific MIS-C guidelines at our institution,” Dr. Dean said, “but like all institutions, we are dealing with the broad definition of MIS-C according to the World Health Organization and the CDC, which is really the takeaway from this paper.”
More difficult differentiation
Both groups of authors pointed out that, as SARS-CoV-2 spreads throughout a community, a higher percentage of the population will have positive results on antibody testing, and such results will become less useful for differentiating between MIS-C and other conditions.
Despite these series’ cautionary lessons, other experts point to the critical importance of including MIS-C early on in the interest of efficient diagnosis and therapy. “In the cases cited, other pathologies were evaluated for and treated accordingly,” said Kara Gross Margolis, MD, AGAF, an associate professor of pediatrics in the division of pediatric gastroenterology, hepatology, and nutrition at Morgan Stanley Children’s Hospital,New York. “These papers stress the need for a balance that is important, and all potential diagnoses need to be considered, but MIS-C, due to its potential severe consequences, also needs to be on our differential now.”
In her view, as this new high-morbidity entity becomes more widespread during the pandemic, it will be increasingly important to keep this condition on the diagnostic radar.
Interestingly, in a converse example of diagnostic clouding, Dr. Gross Margolis’s group reported (Gastroenterology. 2020 Oct;159[4]:1571-4.e2) last year on a pediatric case series in which the presence of gastrointestinal symptoms in children with COVID-19–related MIS-C muddied the diagnosis by confusing this potentially severe syndrome with more common and less toxic gastrointestinal infections.
According to Dr. Smart, although the two reports don’t offer evidence for a particular diagnostic practice, they can inform the decision-making process. “It may be that we will have enough evidence shortly to say what the best practice is regarding diagnostic evaluation of possible MIS-C cases,” he said. “Until then, we must remember that common things occur commonly, even during a global pandemic.”
Neither of the two reports received any specific funding. The authors disclosed no relevant financial relationships.

Interestingly, in a converse example of diagnostic clouding, Dr. Gross Margolis’s group reported (Gastroenterology. 2020 Oct;159[4]:1571-4.e2) last year on a pediatric case series in which the presence of gastrointestinal symptoms in children with COVID-19–related MIS-C muddied the diagnosis by confusing this potentially severe syndrome with more common and less toxic gastrointestinal infections.
According to Dr. Smart, although the two reports don’t offer evidence for a particular diagnostic practice, they can inform the decision-making process. “It may be that we will have enough evidence shortly to say what the best practice is regarding diagnostic evaluation of possible MIS-C cases,” he said. “Until then, we must remember that common things occur commonly, even during a global pandemic.”
Neither of the two reports received any specific funding. The authors disclosed no relevant financial relationships.

The emergence of multiple inflammatory syndrome in children (MIS-C) in association with COVID-19 may be complicating the investigation and diagnosis of more common viral and bacterial infections, potentially delaying treatment and prolonging hospital stays.
Two recent articles published online in Hospital Pediatrics provide evidence of this phenomenon. The articles outlined case studies of children who underwent extensive investigation for MIS-C when in fact they had less severe and more common infections. MIS-C is a severe but rare syndrome that involves systemic hyperinflammation with fever and multisystem organ dysfunction similar to that of Kawasaki disease (KD).
In one of the articles, Matthew Molloy, MD, MPH, of the division of pediatric hospital medicine at Cincinnati Children’s Hospital Medical Center, and colleagues aptly asked: “What are we missing in our search for MIS-C?”
E. coli, not SARS-CoV-2
That question arose from a case involving a 3-year-old boy who had a 6-day history of fever and fatigue. Three days earlier, he had tested negative for strep antigen and COVID-19. He had a persistent, high fever, reduced appetite, and reduced urine output and was taken to the ED. On physical examination, there was no rash, skin peeling, redness of the eye or oral mucosa, congestion, rhinorrhea, cough, shortness of breath, chest pain, abdominal pain, nausea, vomiting, or diarrhea.
Urinalysis results and exam findings were suspicious for pyelonephritis. Other findings from an extensive laboratory workup raised the alarm that the boy was suffering from MIS-C as opposed to incomplete KD. After admission to hospital medicine, the cardiology, rheumatology, and infectious disease teams were called in to consult.
Repeat labs were planned for the following day before initiating therapy. On day 2, the child’s urine culture was positive for gram-negative rods, later identified as Escherichia coli. The boy was started on ceftriaxone. Left renal scarring was apparent on ultrasound. The patient’s condition resolved after 36 hours, and he was discharged home with antibiotics.
‘Diagnosis derailed’
Calling this a case of “diagnosis derailed,” the authors noted that, in the pre-COVID era, this child’s signs and symptoms would likely have triggered a more targeted and less costly evaluation for more common infectious and noninfectious causes, including pyelonephritis, absent any physical exam findings consistent with KD.
“However, the patient presented in the midst of the COVID-19 pandemic with growing awareness of a new clinical entity,” Dr. Molloy and colleagues wrote. “Anchored to the patient’s persistent fever, the medical team initiated an extensive, costly, and ultimately unnecessary workup to avoid missing the diagnosis of MIS-C; a not yet well-described diagnosis with potentially severe morbidity.”
Confirmation bias and diagnostic momentum likely contributed to the early focus on MIS-C rather than more common alternatives, the authors acknowledged. The addition of mildly abnormal laboratory data not typically obtained in the evaluation of fever led the team astray. “The diagnosis and definitive treatment may have been made earlier had the focus on concern for MIS-C not been present,” Dr. Molloy said in an interview.
Keeping value in care
The authors recognized that their initial approach to evaluating for MIS-C provided low-value care. “In our desire to not ‘miss’ MIS-C, we were performing costly evaluations that at times produced mildly abnormal, nonspecific results,” they wrote. That triggered a cascade of specialty consultations, follow-up testing, and an unwarranted diagnostic preoccupation with MIS-C.
Determining the extra price tag for the child’s workup would be complex and difficult because there is a difference in the cost to the hospital and the cost to the family, Dr. Molloy said. “However, there are potential cost savings that would be related to making a correct diagnosis in a timely manner in terms of preventing downstream effects from delayed diagnoses.”
Even as clinicians struggle with the challenging SARS-CoV-2 learning curve, Dr. Molloy and associates urged them to continue to strive for high-value care, with an unwavering focus on using only necessary resources, a stewardship the pandemic has shown to be critical.
“The COVID-19 pandemic has been an incredibly stressful time for physicians and for families,” Dr. Molloy said. “COVID-19 and related conditions like MIS-C are new, and we are learning more and more about them every week. These diagnoses are understandably on the minds of physicians and families when children present with fever.” Notwithstanding, the boy’s case underscores the need for clinicians to consider alternate diagnoses and the value of the care provided.
Impact of bias
Dr. Molloy’s group brings home the cognitive biases practitioners often suffer from, including anchoring and confirmation bias and diagnostic momentum, according to J. Howard Smart, MD, chief of pediatrics at Sharp Mary Birch Hospital for Women and Newborns, San Diego, and an assistant clinical professor of pediatrics at University of California, San Diego.
“But it is one thing to recognize these in retrospect and quite another to consider whether they may be happening to you yourself in real time,” he said in an interview. “It is almost as if we need to have a ‘time out,’ where we stop and ask ourselves whether there is something else that could be explaining our patient’s presentation, something that would be more common and more likely to be occurring.”
According to Dr. Smart, who was not involved in Dr. Molloy’s study, the team’s premature diagnostic focus on MIS-C was almost the inverse of what typically happens with KD. “It is usually the case that Kawasaki disease does not enter the differential diagnosis until late in the course of the fever, typically on day 5 or later, when it may have been better to think of it earlier,” he said.
In the second article, Andrea Dean, MD, of the department of pediatrics at Baylor College of Medicine and Texas Children’s Hospital, both in Houston, and colleagues outlined the cases of five patients aged 8-17 years who were hospitalized in May 2020 for suspected MIS-C. They exhibited inflammatory and other concerning indicators but were eventually discharged with a diagnosis of murine typhus.
This flea-borne infection, most commonly reported in the United States in the southeastern Gulf Coast region, Hawaii, and California, is often associated with a triad of fever, rash, and headache.
Cases have been rising in southern Texas, and Dr. Dean and colleagues postulated that school closures and social distancing may have increased exposure as a result of children spending more time outdoors or with pets. “Alternatively, parental concern for SARS-CoV-2 infection could mean children with symptoms are presenting to care and being referred or admitted to the hospital more frequently due to provider concern for MIS-C,” they wrote.
Cardiac involvement
The most concerning of the five cases in terms of possible MIS-C, Dr. Dean said in an interview, was that of a 12-year-old boy who had fever for 6 days in association with headache, eczematous rash, dry lips, and conjunctivitis. Laboratory tests showed a mildly elevated C-reactive protein level, hyponatremia, and thrombocytopenia, as well as sterile pyuria and mildly elevated prothrombin time. He was treated empirically with doxycycline, and his fever resolved over the next 24 hours.
An echocardiogram at initial evaluation, however, revealed mild dilation of the left anterior descending and right coronary arteries, which led to the administration of intravenous immunoglobulin and aspirin for atypical KD, in contrast to MIS-C. The authors postulated that mild cardiac involvement in disorders other than MIS-C and KD may be underrecognized.
The lesson from these cases, Dr. Dean and associates concluded, is that hospitalists must maintain a wide differential diagnosis when assessing a child with prolonged fever and evidence of systemic inflammation. The CDC stipulates that a diagnosis of MIS-C requires the absence of a plausible alternative diagnosis.
In addition to common viral, bacterial, and noninfectious disorders, a range of regional endemic rickettsial and parasitic infections must be considered as alternative diagnoses to MIS-C. “Many of these diseases cannot be reliably differentiated from MIS-C on presentation, and as community exposure to SARS-CoV-2 grows, hospitalists should be prepared to admit febrile children with evidence of systemic inflammation for brief observation periods to evaluate for MIS-C,” Dr. Dean’s group wrote. In this context, however, empiric treatment for common or even uncommon infectious diseases may avoid overdiagnosis and overtreatment of MIS-C as well as improve patient outcomes.
“We do have specific MIS-C guidelines at our institution,” Dr. Dean said, “but like all institutions, we are dealing with the broad definition of MIS-C according to the World Health Organization and the CDC, which is really the takeaway from this paper.”
More difficult differentiation
Both groups of authors pointed out that, as SARS-CoV-2 spreads throughout a community, a higher percentage of the population will have positive results on antibody testing, and such results will become less useful for differentiating between MIS-C and other conditions.
Despite these series’ cautionary lessons, other experts point to the critical importance of including MIS-C early on in the interest of efficient diagnosis and therapy. “In the cases cited, other pathologies were evaluated for and treated accordingly,” said Kara Gross Margolis, MD, AGAF, an associate professor of pediatrics in the division of pediatric gastroenterology, hepatology, and nutrition at Morgan Stanley Children’s Hospital,New York. “These papers stress the need for a balance that is important, and all potential diagnoses need to be considered, but MIS-C, due to its potential severe consequences, also needs to be on our differential now.”

Over half of COVID-19 transmission may occur via asymptomatic people
As COVID-19 cases surge and vaccinations lag, health authorities continue to seek additional ways to mitigate the spread of the novel coronavirus.
Now, a modeling study estimates that more than half of transmissions come from pre-, never-, and asymptomatic individuals, indicating that symptom-based screening will have little effect on spread.
The Centers for Disease Control and Prevention study, published online Jan. 7 in JAMA Network Open, concludes that for optimal control, protective measures such as masking and social distancing should be supplemented with strategic testing of potentially exposed but asymptomatic individuals .
“In the absence of effective and widespread use of therapeutics or vaccines that can shorten or eliminate infectivity, successful control of SARS-CoV-2 cannot rely solely on identifying and isolating symptomatic cases; even if implemented effectively, this strategy would be insufficient,” CDC biologist Michael J. Johansson, PhD, and colleagues warn. “Multiple measures that effectively address transmission risk in the absence of symptoms are imperative to control SARS-CoV-2.”
According to the authors, the effectiveness of some current transmission prevention efforts has been disputed and subject to mixed messaging. Therefore, they decided to model the proportion of COVID-19 infections that are likely the result of individuals who show no symptoms and may be unknowingly infecting others.
“Unfortunately, there continues to be some skepticism about the value of community-wide mitigation efforts for preventing transmission such as masking, distancing, and hand hygiene, particularly for people without symptoms,” corresponding author Jay C. Butler, MD, said in an interview. “So we wanted to have a base assumption about how much transmission occurs from asymptomatic people to underscore the importance of mitigation measures and of creating immunity through vaccine delivery.”
Such a yardstick is especially germane in the context of the new, more transmissible variant. “It really puts [things] in a bigger box and underscores, boldfaces, and italicizes the need to change people’s behaviors and the importance of mitigation,” Dr. Butler said. It also highlights the advisability of targeted strategic testing in congregate settings, schools, and universities, which is already underway.
The analysis
Based on data from several COVID-19 studies from last year, the CDC’s analytical model assumes at baseline that infectiousness peaks at the median point of symptom onset, and that 30% of infected individuals never develop symptoms but are nevertheless 75% as infectious as those who develop overt symptoms.
The investigators then model multiple scenarios of transmission based pre- and never-symptomatic individuals, assuming different incubation and infectious periods, and varying numbers of days from point of infection to symptom onset.
When combined, the models predicts that 59% of all transmission would come from asymptomatic transmission – 35% from presymptomatic individuals and 24% from never-symptomatic individuals.
The findings complement those of an earlier CDC analysis, according to the authors.
The overall proportion of transmission from presymptomatic and never-symptomatic individuals is key to identifying mitigation measures that may be able to control SARS-CoV-2, the authors stated.
For example, they explain, if the infection reproduction number (R) in a particular setting is 2.0, a reduction in transmission of at least 50% is needed in order to reduce R to below 1.0. “Given that in some settings R is likely much greater than 2 and more than half of transmissions may come from individuals who are asymptomatic at the time of transmission, effective control must mitigate transmission risk from people without symptoms,” they wrote.
The authors acknowledge that the study applies a simplistic model to a complex and evolving phenomenon, and that the exact proportions of presymptomatic and never-symptomatic transmission and the incubation periods are not known. They also note symptoms and transmissions appear to vary across different population groups, with older individuals more likely than younger persons to experience symptoms, according to previous studies.
“Assume that everyone is potentially infected”
Other experts agree that expanded testing of asymptomatic individuals is important. “Screening for fever and isolation of symptomatic individuals is a common-sense approach to help prevent spread, but these measures are by no means adequate since it’s been clearly documented that individuals who are either asymptomatic or presymptomatic can still spread the virus,” said Brett Williams, MD, an infectious disease specialist and assistant professor of medicine at Rush University in Chicago.
“As we saw with the White House Rose Garden superspreader outbreak, testing does not reliably exclude infection either because the tested individual has not yet become positive or the test is falsely negative,” Dr. Williams, who was not involved in the CDC study, said in an interview. He further noted that when prevalence is as high as it currently is in the United States, the rate of false negatives will be high because a large proportion of those screened will be unknowingly infected.
At his center, all visitors and staff are screened with a temperature probe on entry, and since the earliest days of the pandemic, universal masking has been required. “Nationally there have been many instances of hospital break room outbreaks because of staff eating lunch together, and these outbreaks also demonstrate the incompleteness of symptomatic isolation,” Dr. Williams said.
For his part, virologist Frank Esper, MD, a pediatric infectious disease specialist at the Cleveland Clinic, said that while it’s been understood for some time that many infected people will not exhibit symptoms, “the question that remains is just how infectious are they?”
Dr. Esper’s takeaway from the modeling study is not so much that we need more screening of possibly exposed but asymptomatic people, but rather testing symptomatic people and tracing their contacts is not enough.
“We need to continue to assume that everyone is potentially infected whether they know it or not. And even though we have ramped up our testing to a much greater capacity than in the first wave, we need to continue to wear masks and socially distance because just identifying people who are sick and isolating or quarantining them is not going to be enough to contain the pandemic.”
And although assumption-based modeling is helpful, it cannot tell us “how many asymptomatic people are actually infected,” said Dr. Esper, who was not involved in the CDC study.
Dr. Esper also pointed out that the study estimates are based on data from early Chinese studies, but the virus has since changed. The new, more transmissible strain in the United States and elsewhere may involve not only more infections but also a longer presymptomatic stage. “So the CDC study may actually undershoot asymptomatic infections,” he said.
He also agreed with the authors that when it comes to infection, not all humans are equal. “Older people tend to be more symptomatic and become symptomatic more quickly so the asymptomatic rate is not the same across board from young people age 20 to older people.”
The bottom line, said David. A. Hirschwerk, MD, an infectious disease specialist at Northwell Health in Manhasset, N.Y., is that these data support the maintenance of protective measures we’ve been taking over the past months. “They support the concept that asymptomatic people are a significant source of transmission and that we need to adhere to mask wearing and social distancing, particularly indoors,” Dr. Hirschwerk, who was not involved in the analysis, said in an interview. “More testing would be better but it has to be fast and it has to be efficient, and there are a lot of challenges to overcome.”
The study was done as part of the CDC’s coronavirus disease 2019 response and was supported solely by federal base and response funding. The authors and commentators have disclosed no relevant financial relationships.

Add delirium to checklist of COVID-19 symptoms in seniors
Delirium should be included on checklists of the presenting signs and symptoms of COVID-19, particularly in elderly adults, according to a multicenter study of seniors visiting emergency departments.
Overall, 28% of the 817 older adults who presented to the emergency department and were diagnosed with COVID-19 had delirium, according to a study published online November 19 in JAMA Network Open. Moreover, 16% of these patients had delirium that was not accompanied by typical symptoms or signs of SARS-CoV-2 infection.
Among patients with delirium, there was a greater probability of admission to the intensive care unit compared with patients who presented without delirium (adjusted relative risk [aRR], 1.67; 95% CI, 1.30 – 2.15), as well as a greater probability of death (aRR, 1.24; 95% CI, 1.00 – 1.55).
“These findings suggest the clinical importance of including delirium on checklists of presenting signs and symptoms of COVID-19 that guide screening, testing, and evaluation,” write Maura Kennedy, MD, MPH, and colleagues.
“I was absolutely seeing cases of delirium where there were no other symptoms of COVID-19, but we didn’t have lot of data on the frequency of this,” explained Kennedy, an emergency department physician at Massachusetts General Hospital and an assistant professor of emergency medicine at Harvard Medical School, Boston.
“And the rate was somewhat surprising compared with that seen in non-COVID studies of delirium, but then our study population was more at risk, coming from long-term care facilities and having prior stroke or dementia,” she said. The most common form of delirium was hypoactive sleepiness and nonresponsiveness, although hyperactivity and agitation were also seen.
Kennedy thinks the addition of delirium as a common presenting symptom to diagnostic checklists would prevent some cases from being missed and allow earlier identification and management of COVID-19 patients at high risk for poor outcomes. “We certainly don’t want to send them back undiagnosed to a long-term care facility or promote transmission within the hospital,” she told Medscape Medical News.
That step has already been implemented in some US centers. “Delirium is something we’ve been looking at since the early summer,” said geriatrician Angela Catic, MD, an assistant professor at Baylor College of Medicine’s Huffington Center on Aging and the Michael E.

“If we see delirium, we’re looking for COVID-19,” said Catic, who was not involved in the study.
In Catic’s experience, it is “not at all atypical” to see patients whose only symptom of COVID-19 is delirium. As with other infections and diseases, “the aging brain is incredibly vulnerable,” she said.
According to William W. Hung, MD, MPH, an assistant professor of geriatrics and palliative medicine at the Icahn School of Medicine at Mount Sinai, New York City, delirium is “generally a common sign of something seriously wrong” in older adults. “In the case of COVID-19, low oxygenation caused by the infection may play a role,” he told Medscape Medical News. Although he agreed that delirium should be included in the differential diagnosis of COVID-19, how frequently it is the only symptom at presentation would need to be determined in a considerably larger population, he said.
Joining the company of those observing this COVID-19 manifestation is Christopher R. Carpenter, MD, a professor of emergency medicine at Washington University in St. Louis, St. Louis, Missouri. He was not a participant in the current study.
“I have absolutely seen and documented delirium as the presenting complaint in older adult patients who were ultimately diagnosed with SARS-CoV-2, and since March, I contemplate SARS-CoV-2 each time I identify delirium,” Carpenter told Medscape Medical News. “Honestly, I ― and most of my colleagues ― are considering SARS-CoV-2 for a range of symptoms and complaints these days, because of the odd presentations we’ve all encountered.”
Study details
For the study, Kennedy and colleagues enrolled consecutive adults aged 65 years and older who were diagnosed with active COVID-19 and who presented to emergency departments at seven centers in Massachusetts, Maine, Connecticut, Michigan, and North Carolina on or after March 13, 2020. Active infection with SARS-CoV-2 was determined on the basis of results of nasal swab polymerase chain reaction tests (99% of cases) or the appearance and distribution of ground-glass opacities on chest radiography or CT (1%).
Of the 817 patients enrolled, 386 (47%) were men, 493 (62%) were White, 215 (27%) were Black, and 54 (7%) were Hispanic or Latinx. The mean age of patients was 77.7 years (standard deviation, 8.2). Their age placed them at risk for chronic comorbidities and cognitive problems; indeed, 15% had at least four chronic conditions, and 30% had existing cognitive impairment.
The authors note that among the 226 patients (28%) who had delirium at presentation, 60 (27%) had experienced delirium for a duration of 2 to 7 days.
Additionally, of the 226 patients who exhibited delirium as a primary symptom, 84 (37%) showed no typical COVID-19 symptoms or signs, such as cough, fever, or shortness of breath.
The presence of delirium did not correlate with any of the typical COVID-19 symptoms in particular; Kennedy noted that only 56% of patients in the cohort had a fever at presentation.
Delirium at presentation was significantly associated with a median hospital stay of more than 8 days (aRR, 1.14; 95% CI, .97 – 1.35) and a greater risk for discharge to a rehabilitation facility (aRR, 1.55; 95% CI, 1.07 – 2.26). Factors associated with delirium included age older than 75 years, residence in a nursing home or assisted-living facility, previous use of psychoactive medications, vision impairment, hearing impairment, stroke, and Parkinson’s disease.
Kennedy noted that the rate of delirium observed in this study is much higher than that generally reported in emergency department studies conducted before the COVID-19 pandemic. In those studies, the delirium rate ranged from 7% to 20%. The associated risk factors, however, are comparable.
“Mounting evidence supports the high occurrence of delirium and other neuropsychiatric manifestations with COVID-19, with previously reported rates of 22% to 33% among hospitalized patients,” Kennedy and associates write.
In Carpenter’s opinion, the development of incident delirium while receiving care in the emergency department, as opposed to delirium at the time of presentation, has been exacerbated by the no-visitor policies mandated by the pandemic, which have prevented visits even from personal caregivers of patients with moderate to severe dementia. “Although healthcare systems need to be cognizant of the risk of spread to uninfected caregivers, there’s a risk-benefit balance that must be found, because having one caregiver at the bedside can prevent delirium in cognitively impaired patients,” said Carpenter, who was not involved in the current study.
Among the barriers to improving the situation, Carpenter cited the lack of routine delirium screening and the absence of high-quality evidence to support emergency department interventions to mitigate delirium.
“Layer those challenges on top of COVID-19’s rapidly evolving diagnostic landscape, frequent atypical presentations, and asymptomatic carriers across all age groups and the negative impact of delirium is magnified,” Carpenter said.
Once elderly patients are hospitalized, Kennedy recommends the nonpharmacologic guidelines of the Hospital Elder Life Program for reducing delirium risk. Recommendations include the providing of adequate sleep, hydration, and nutrition, as well as function restoration, precipitant avoidance, and reorientation.
The study was supported in part by the National Institute on Aging and the Massachusetts Medical School. The authors, Carpenter, Hung, and Catic have disclosed no relevant financial relationships.

Delirium should be included on checklists of the presenting signs and symptoms of COVID-19, particularly in elderly adults, according to a multicenter study of seniors visiting emergency departments.
Overall, 28% of the 817 older adults who presented to the emergency department and were diagnosed with COVID-19 had delirium, according to a study published online November 19 in JAMA Network Open. Moreover, 16% of these patients had delirium that was not accompanied by typical symptoms or signs of SARS-CoV-2 infection.
Among patients with delirium, there was a greater probability of admission to the intensive care unit compared with patients who presented without delirium (adjusted relative risk [aRR], 1.67; 95% CI, 1.30 – 2.15), as well as a greater probability of death (aRR, 1.24; 95% CI, 1.00 – 1.55).
“These findings suggest the clinical importance of including delirium on checklists of presenting signs and symptoms of COVID-19 that guide screening, testing, and evaluation,” write Maura Kennedy, MD, MPH, and colleagues.
“I was absolutely seeing cases of delirium where there were no other symptoms of COVID-19, but we didn’t have lot of data on the frequency of this,” explained Kennedy, an emergency department physician at Massachusetts General Hospital and an assistant professor of emergency medicine at Harvard Medical School, Boston.
“And the rate was somewhat surprising compared with that seen in non-COVID studies of delirium, but then our study population was more at risk, coming from long-term care facilities and having prior stroke or dementia,” she said. The most common form of delirium was hypoactive sleepiness and nonresponsiveness, although hyperactivity and agitation were also seen.
Kennedy thinks the addition of delirium as a common presenting symptom to diagnostic checklists would prevent some cases from being missed and allow earlier identification and management of COVID-19 patients at high risk for poor outcomes. “We certainly don’t want to send them back undiagnosed to a long-term care facility or promote transmission within the hospital,” she told Medscape Medical News.
That step has already been implemented in some US centers. “Delirium is something we’ve been looking at since the early summer,” said geriatrician Angela Catic, MD, an assistant professor at Baylor College of Medicine’s Huffington Center on Aging and the Michael E. DeBakey VA Medical Center, Houston, Texas.

Biometric changes on fitness trackers, smartwatches detect COVID-19
A smartphone app that combines passively collected physiologic data from wearable devices, such as fitness trackers, and self-reported symptoms can discriminate between COVID-19–positive and –negative individuals among those who report symptoms, new data suggest.
After analyzing data from more than 30,000 participants, researchers from the Digital Engagement and Tracking for Early Control and Treatment (DETECT) study concluded that adding individual changes in sensor data improves models based on symptoms alone for differentiating symptomatic persons who are COVID-19 positive and symptomatic persons who are COVID-19 negative.
The combination can potentially identify infection clusters before wider community spread occurs, Giorgio Quer, PhD, and colleagues report in an article published online Oct. 29 in Nature Medicine. DETECT investigators note that marrying participant-reported symptoms with personal sensor data, such as deviation from normal sleep duration and resting heart rate, resulted in an area under the curve (AUC) of 0.80 (interquartile range [IQR], 0.73-0.86) for differentiating between symptomatic individuals who were positive and those who were negative for COVID-19.
“By better characterizing each individual’s unique baseline, you can then identify changes that may indicate that someone has a viral illness,” said Dr. Quer, director of artificial intelligence at Scripps Research Translational Institute in La Jolla, Calif. “In previous research, we found that the proportion of individuals with elevated resting heart rate and sleep duration compared with their normal could significantly improve real-time detection of influenza-like illness rates at the state level,” he said in an interview.
Thus, continuous passively captured data may be a useful adjunct to bricks-and-mortar site testing, which is generally a one-off or infrequent sampling assay and is not always easily accessible, he added. Furthermore, traditional screening with temperature and symptom reporting is inadequate. An elevation in temperature is not as common as frequently believed for people who test positive for COVID-19, Dr. Quer continued. “Early identification via sensor variables of those who are presymptomatic or even asymptomatic would be especially valuable, as people may potentially be infectious during this period, and early detection is the ultimate goal,” Dr. Quer said.
According to his group, adding these physiologic changes from baseline values significantly outperformed detection (P < .01) using a British model described in an earlier study by by Cristina Menni, PhD, and associates. That method, in which symptoms were considered alone, yielded an AUC of 0.71 (IQR, 0.63-0.79).
According to Dr. Quer, one in five Americans currently wear an electronic device. “If we could enroll even a small percentage of these individuals, we’d be able to potentially identify clusters before they have the opportunity to spread,” he said.
DETECT study details
During the period March 15 to June 7, 2020, the study enrolled 30,529 participants from all 50 states. They ranged in age from younger than 35 years (23.1%) to older than 65 years (12.8%); the majority (63.5%) were aged 35-65 years, and 62% were women. Sensor devices in use by the cohort included Fitbit activity trackers (78.4%) and Apple HealthKit (31.2%).
Participants downloaded an app called MyDataHelps, which collects smartwatch and activity tracker information, including self-reported symptoms and diagnostic testing results. The app also monitors changes from baseline in resting heart rate, sleep duration, and physical activity, as measured by steps.
Overall, 3,811 participants reported having at least one symptom of some kind (e.g., fatigue, cough, dyspnea, loss of taste or smell). Of these, 54 reported testing positive for COVID-19, and 279 reported testing negative.
Sleep and activity were significantly different for the positive and negative groups, with an AUC of 0.68 (IQR, 0.57-0.79) for the sleep metric and 0.69 (IQR, 0.61-0.77) for the activity metric, suggesting that these parameters were more affected in COVID-19–positive participants.
When the investigators combined resting heart rate, sleep, and activity into a single metric, predictive performance improved to an AUC of 0.72 (IQR, 0.64-0.80).
The next step, Dr. Quer said, is to include an alert to notify users of possible infection.
Alerting users to possible COVID-19 infection
In a similar study, an alert feature was already incorporated. The study, led by Michael P. Snyder, PhD, director of the Center for Genomics and Personalized Medicine at Stanford (Calif.) University, will soon be published online in Nature Biomedical Engineering. In that study, presymptomatic detection of COVID-19 was achieved in more than 80% of participants using resting heart rate.
“The median is 4 days prior to symptom formation,” Dr. Snyder said in an interview. “We have an alarm system to notify people when their heart rate is elevated. So a positive signal from a smartwatch can be used to follow up by polymerase chain reaction [testing].”
Dr. Snyder said these approaches offer a roadmap to containing widespread infections. “Public health authorities need to be open to these technologies and begin incorporating them into their tracking,” he said. “Right now, people do temperature checks, which are of limited value. Resting heart rate is much better information.”
Although the DETECT researchers have not yet received feedback on their results, they believe public health authorities could recommend the use of such apps. “These are devices that people routinely wear for tracking their fitness and sleep, so it would be relatively easy to use the data for viral illness tracking,” said co–lead author Jennifer Radin, PhD, an epidemiologist at Scripps. “Testing resources are still limited and don’t allow for routine serial testing of individuals who may be asymptomatic or presymptomatic. Wearables can offer a different way to routinely monitor and screen people for changes in their data that may indicate COVID-19.”
The marshaling of data through consumer digital platforms to fight the coronavirus is gaining ground. New York State and New Jersey are already embracing smartphone apps to alert individuals to possible exposure to the virus.
More than 710,000 New Yorkers have downloaded the COVID NY Alert app, launched in October to help protect individuals and communities from COVID-19 by sending alerts without compromising privacy or personal information. “Upon receiving a notification about a potential exposure, users are then able to self-quarantine, get tested, and reduce the potential exposure risk to family, friends, coworkers, and others,” Jonah Bruno, a spokesperson for the New York State Department of Health, said in an interview.
And recently the Mayo Clinic and Safe Health Systems launched a platform to store COVID-19 testing and vaccination data.
Both the Scripps and Stanford platforms are part of a global technologic response to the COVID-19 pandemic. Prospective studies, led by device manufacturers and academic institutions, allow individuals to voluntarily share sensor and clinical data to address the crisis. Similar approaches have been used to track COVID-19 in large populations in Germany via the Corona Data Donation app.
The study by Dr. Quer and colleagues was funded by a grant from the National Center for Advancing Translational Sciences at the National Institutes of Health. One coauthor reported grants from Janssen and personal fees from Otsuka and Livongo outside of the submitted work. The other authors have disclosed no relevant financial relationships. Dr. Snyder has ties to Personalis, Qbio, January, SensOmics, Protos, Mirvie, and Oralome.

A smartphone app that combines passively collected physiologic data from wearable devices, such as fitness trackers, and self-reported symptoms can discriminate between COVID-19–positive and –negative individuals among those who report symptoms, new data suggest.
After analyzing data from more than 30,000 participants, researchers from the Digital Engagement and Tracking for Early Control and Treatment (DETECT) study concluded that adding individual changes in sensor data improves models based on symptoms alone for differentiating symptomatic persons who are COVID-19 positive and symptomatic persons who are COVID-19 negative.
The combination can potentially identify infection clusters before wider community spread occurs, Giorgio Quer, PhD, and colleagues report in an article published online Oct. 29 in Nature Medicine. DETECT investigators note that marrying participant-reported symptoms with personal sensor data, such as deviation from normal sleep duration and resting heart rate, resulted in an area under the curve (AUC) of 0.80 (interquartile range [IQR], 0.73-0.86) for differentiating between symptomatic individuals who were positive and those who were negative for COVID-19.
“By better characterizing each individual’s unique baseline, you can then identify changes that may indicate that someone has a viral illness,” said Dr. Quer, director of artificial intelligence at Scripps Research Translational Institute in La Jolla, Calif. “In previous research, we found that the proportion of individuals with elevated resting heart rate and sleep duration compared with their normal could significantly improve real-time detection of influenza-like illness rates at the state level,” he said in an interview.
Thus, continuous passively captured data may be a useful adjunct to bricks-and-mortar site testing, which is generally a one-off or infrequent sampling assay and is not always easily accessible, he added. Furthermore, traditional screening with temperature and symptom reporting is inadequate. An elevation in temperature is not as common as frequently believed for people who test positive for COVID-19, Dr. Quer continued. “Early identification via sensor variables of those who are presymptomatic or even asymptomatic would be especially valuable, as people may potentially be infectious during this period, and early detection is the ultimate goal,” Dr. Quer said.
According to his group, adding these physiologic changes from baseline values significantly outperformed detection (P < .01) using a British model described in an earlier study by by Cristina Menni, PhD, and associates. That method, in which symptoms were considered alone, yielded an AUC of 0.71 (IQR, 0.63-0.79).
According to Dr. Quer, one in five Americans currently wear an electronic device. “If we could enroll even a small percentage of these individuals, we’d be able to potentially identify clusters before they have the opportunity to spread,” he said.
DETECT study details
During the period March 15 to June 7, 2020, the study enrolled 30,529 participants from all 50 states. They ranged in age from younger than 35 years (23.1%) to older than 65 years (12.8%); the majority (63.5%) were aged 35-65 years, and 62% were women. Sensor devices in use by the cohort included Fitbit activity trackers (78.4%) and Apple HealthKit (31.2%).
Participants downloaded an app called MyDataHelps, which collects smartwatch and activity tracker information, including self-reported symptoms and diagnostic testing results. The app also monitors changes from baseline in resting heart rate, sleep duration, and physical activity, as measured by steps.
Overall, 3,811 participants reported having at least one symptom of some kind (e.g., fatigue, cough, dyspnea, loss of taste or smell). Of these, 54 reported testing positive for COVID-19, and 279 reported testing negative.
Sleep and activity were significantly different for the positive and negative groups, with an AUC of 0.68 (IQR, 0.57-0.79) for the sleep metric and 0.69 (IQR, 0.61-0.77) for the activity metric, suggesting that these parameters were more affected in COVID-19–positive participants.
When the investigators combined resting heart rate, sleep, and activity into a single metric, predictive performance improved to an AUC of 0.72 (IQR, 0.64-0.80).
The next step, Dr. Quer said, is to include an alert to notify users of possible infection.
Alerting users to possible COVID-19 infection
In a similar study, an alert feature was already incorporated. The study, led by Michael P. Snyder, PhD, director of the Center for Genomics and Personalized Medicine at Stanford (Calif.) University, will soon be published online in Nature Biomedical Engineering. In that study, presymptomatic detection of COVID-19 was achieved in more than 80% of participants using resting heart rate.
“The median is 4 days prior to symptom formation,” Dr. Snyder said in an interview. “We have an alarm system to notify people when their heart rate is elevated. So a positive signal from a smartwatch can be used to follow up by polymerase chain reaction [testing].”
Dr. Snyder said these approaches offer a roadmap to containing widespread infections. “Public health authorities need to be open to these technologies and begin incorporating them into their tracking,” he said. “Right now, people do temperature checks, which are of limited value. Resting heart rate is much better information.”
Although the DETECT researchers have not yet received feedback on their results, they believe public health authorities could recommend the use of such apps. “These are devices that people routinely wear for tracking their fitness and sleep, so it would be relatively easy to use the data for viral illness tracking,” said co–lead author Jennifer Radin, PhD, an epidemiologist at Scripps. “Testing resources are still limited and don’t allow for routine serial testing of individuals who may be asymptomatic or presymptomatic. Wearables can offer a different way to routinely monitor and screen people for changes in their data that may indicate COVID-19.”
The marshaling of data through consumer digital platforms to fight the coronavirus is gaining ground. New York State and New Jersey are already embracing smartphone apps to alert individuals to possible exposure to the virus.
More than 710,000 New Yorkers have downloaded the COVID NY Alert app, launched in October to help protect individuals and communities from COVID-19 by sending alerts without compromising privacy or personal information. “Upon receiving a notification about a potential exposure, users are then able to self-quarantine, get tested, and reduce the potential exposure risk to family, friends, coworkers, and others,” Jonah Bruno, a spokesperson for the New York State Department of Health, said in an interview.
And recently the Mayo Clinic and Safe Health Systems launched a platform to store COVID-19 testing and vaccination data.
Both the Scripps and Stanford platforms are part of a global technologic response to the COVID-19 pandemic. Prospective studies, led by device manufacturers and academic institutions, allow individuals to voluntarily share sensor and clinical data to address the crisis. Similar approaches have been used to track COVID-19 in large populations in Germany via the Corona Data Donation app.

Study results suggest ustekinumab may trigger acute CV events early in treatment
in susceptible patients, according to a large French case-time-control analysis.
Investigators led by Florence Poizeau, MD, of the department of dermatology at Rennes (France) University Hospital, found high-risk patients had more than four times the risk of an acute SCE in the 6 months after starting treatment. Although ustekinumab (Stelara) effectively treats moderate to severe psoriasis, psoriatic arthritis (PsA), and Crohn’s disease (indications approved by the Food and Drug Administration), the early months after ustekinumab initiation may be associated with atherosclerotic plaque destabilization via the inhibition of helper T cell subtype 17, the group reported in JAMA Dermatology.
The observational study drew on France’s 66 million–registrant health insurance database to identify all patients exposed to ustekinumab between April 1, 2010, and Dec. 31, 2016. Classified by high or low cardiovascular risk level, ustekinumab recipients served as their own controls, being compared during two time windows: the risk period covered the 6 months after initiating treatment and leading up to the SCE, defined as acute coronary syndrome (ACS) or stroke, while a reference period spanned the 6-12 months leading up to the risk period.
In the statistical analysis of 9,290 ustekinumab-exposed patients (mean age 43 years, 52% male), conducted from September 2017 to July 2018, 7,588 (82%) received ustekinumab for psoriasis or PsA, and 724 (8%) for Crohn’s disease. (The remaining indications were for psoriasis or PsA and Crohn’s disease, or were undetermined.)
Of these patients, 98 experienced SCEs (52 with ACS admitted to the ICU and 46 with strokes). In patients deemed at high cardiovascular risk – those with two risk factors or a personal history of atherosclerotic disease – there was a statistically significant association between starting ustekinumab and SCE occurrence, for an odds ratio of 4.17 (95% confidence interval, 1.19-14.59). In contrast, no such association emerged in ustekinumab users at low cardiovascular risk, for an OR of 0.30 (95% CI, 0.03-3.13). The OR for all was 2.41 (95% CI, 0.83-7.01).
Of the 98 patients included in the final case-time-control analysis, 62 were men (63%), the median age was 57 years, and 76 (78%) were at high cardiovascular risk. A total of 89 patients (91%) had psoriasis, four (4%) had Crohn’s disease, and two (2%) had both.
The investigators also did an analysis including these 98 patients plus 13 patients with ACS who were not hospitalized in an ICU, and 68 with unstable angina, for a total of 179. In this group, the ORs for SCE were 1.75 (95% CI, 0.86-3.56) overall, compared with 3.20 (95% CI, 1.29-7.92) among those at high cardiovascular risk and 0.21 (95% CI, 0.02-1.69) among those at low cardiovascular risk.
The Rennes investigators’ decision to focus on early SCEs stemmed in part from a meta-analysis of randomized clinical trials that reported a possible excess of early SCEs in adults exposed to anti–IL-12/23p40 antibodies, which at that time included the now-discontinued experimental antibody briakinumab. Briakinumab trials were aborted and the drug was never brought to market, leaving ustekinumab as the only antibody of this type.
The finding of “an association between ustekinumab initiation and SCE among patients with cardiovascular risk factors suggests the need for caution regarding the prescription of ustekinumab in this population,” Dr. Poizeau and colleagues wrote. The risk “seems to concern patients with psoriasis” rather than Crohn’s disease, which may be related to the older age and greater cardiovascular risk of the former. “A close collaboration between cardiologists and biologic prescribers could be beneficial to evaluate the risk of SCEs for patients who are receiving ustekinumab,” they added, recommending further research into the physiopathological mechanisms of action.
Offering a U.S. clinician’s perspective on the French study, Anthony Fernandez, MD, PhD, director of medical dermatology at the Cleveland Clinic, called the findings “unique and interesting with very robust odds ratios. These posttreatment associations have actually been a big area of research over the past decade but not with such defined time periods.”
No significant increases in risk have been seen with other biologics, Dr. Fernandez added, with the exception of briakinumab. “But still, the current study does not definitively answer the question whether ustekinumab can trigger acute events within 6 months of treatment. There’s smoke, but we haven’t clearly seen a fire.”
As to ustekinumab’s possible pathogenic mechanism of action, Dr. Fernandez pointed to data suggesting that IL-17A can be stabilizing to atherosclerotic plaques. “So there’s a hypothesis that blocking the 17/23 pathway may destabilize plaques and make patients more prone to acute cardiovascular events.”
In other comments from clinicians not involved in the study, Seoyoung Kim, MD, ScD, MSCE, director of the program in rheumatologic, immunologic, and musculoskeletal pharmacoepidemiology (PRIME) at Brigham and Women’s Hospital, Boston, noted that, while the investigators controlled for the trend over time and their design choice included time-fixed covariates such as age, sex, and family history within individuals, the case-crossover study could not control for time-varying confounders within individuals.
“In other words, it’s possible that some of the patients had a lot more disease activity and systemic inflammation and used more NSAIDs, steroids, and other medications potentially related to cardiovascular risk a few months before they started ustekinumab, compared with 6-12 months prior,“ Dr. Kim said in an interview. “I would be curious to know if they would find the same thing or not if they studied a different type of biologic drug.”
She also pointed out that the number of outcomes overall was small, leading to imprecise estimates and wide confidence intervals.
Last year Dr. Kim and associates published a study comparing ustekinumab with tumor necrosis factor inhibitor therapy in younger psoriasis and psoriatic arthritis patients and found no difference between the two groups in major cardiovascular events or atrial fibrillation.
Joel M. Gelfand, MD, MSCE, professor of dermatology and epidemiology at the University of Pennsylvania, Philadelphia, has more reservations about the findings. “The Poizeau study was methodologically flawed, making the results unreliable,” he said in an interview. “There is a breadth of data from clinical trials and observational studies that do not demonstrate an increased risk of major acute cardiovascular events with ustekinumab and the results of the Poizeau study should not impact clinical practice.”
In an interview, Mark G. Lebwohl, MD, professor and chairman of the department of dermatology and chief for clinical therapeutics at the Icahn School of Medicine at Mount Sinai, New York, said that, in his view, the investigators used early reports of a small number cardiovascular events to look at the issue from a faulty perspective, and hence their findings would have no impact on his clinical practice.
“This study looked at the issue incorrectly. It looked at people put on drug who already had two risk factors for heart attack. And psoriasis itself is a third risk factor,” he said. “So lo and behold, big surprise, some of them had cardiovascular events.”
Dr. Lebwohl noted that a wealth of carefully compiled data has found no increase over time in cardiovascular events with this drug in psoriasis patients. The risk of cardiovascular events actually goes down with time because of the drug’s anti-inflammatory effects.
Dr. Fernandez takes a more positive view of the French findings. “The data certainly support the need for further research in this area,” he said in an interview, “and in the meantime this paper will probably make me extra cautious in using ustekinumab in those at significant risk.”
The French study was supported by a grant from the French National Agency for Medicines and Health Products Safety. Dr. Poizeau and seven coauthors had no disclosures. The remaining five reported disclosures that included receiving fees from AbbVie, Admiral, Amgen, Baxalta, Cologne, Dermavant, Eli Lilly, Janssen, Kyowa Kirin, Novartis, Mylan, Sun Pharmaceuticals, and UCB, as well as grants and personal fees from Boehringer Ingelheim, Leo Pharma, and Pfizer outside the submitted work, and personal fees from Pfizer, AbbVie, UCB Pharma, and Lilly during the conduct of the study. Dr. Fernandez reported consulting work for AbbVie and research grants from Novartis. Dr. Kim disclosed research grants from Brigham and Women’s Hospital and from Pfizer, Abbvie, Roche, and Bristol-Myers Squibb for unrelated studies. Dr. Gelfand reported varying financial ties to Bristol-Myers Squibb, Boehringer Ingelheim, GlaxoSmithKline, Janssen Biologics, Regeneron, UCB, Sanofi, Pfizer, Celgene, OrthoDermatolgics, AbbVie, Novartis, and Eli Lilly. He is copatent holder of a treatment for cutaneous T-cell lymphoma. Dr. Lebwohl reported unpaid consulting for most manufacturers of psoriasis drugs, with all fees going directly to Mount Sinai.

The remaining five reported disclosures that included receiving fees from AbbVie, Admiral, Amgen, Baxalta, Cologne, Dermavant, Eli Lilly, Janssen, Kyowa Kirin, Novartis, Mylan, Sun Pharmaceuticals, and UCB, as well as grants and personal fees from Boehringer Ingelheim, Leo Pharma, and Pfizer outside the submitted work, and personal fees from Pfizer, AbbVie, UCB Pharma, and Lilly during the conduct of the study. Dr. Fernandez reported consulting work for AbbVie and research grants from Novartis. Dr. Kim disclosed research grants from Brigham and Women’s Hospital and from Pfizer, Abbvie, Roche, and Bristol-Myers Squibb for unrelated studies. Dr. Gelfand reported varying financial ties to Bristol-Myers Squibb, Boehringer Ingelheim, GlaxoSmithKline, Janssen Biologics, Regeneron, UCB, Sanofi, Pfizer, Celgene, OrthoDermatolgics, AbbVie, Novartis, and Eli Lilly. He is copatent holder of a treatment for cutaneous T-cell lymphoma. Dr. Lebwohl reported unpaid consulting for most manufacturers of psoriasis drugs, with all fees going directly to Mount Sinai.

COVID-19 symptoms can linger for months
Clinicians and researchers have focused on the acute phase of COVID-19 infection, but it’s increasingly clear that some recovered patients discharged from acute care need continued monitoring for long-lasting effects, a study has found.
In a research letter published online July 9 in JAMA, Angelo Carfi, MD, and colleagues from the Gemelli Against COVID-19 Post–Acute Care Study Group in Rome, report that
Postdischarge assessments of patients who met criteria for SARS-CoV-2 negativity, including a reverse transcriptase–polymerase chain reaction test, were conducted from April 21 to May 29. Among the results:
- Only 12.6% of the 143 patients were completely free of any COVID-19 symptom
- About 32% of patients had one or two symptoms and 55% had three or more
- None had fever or other signs and symptoms of acute illness
- About 53% of patients still had fatigue, 43.4% had dyspnea, 27.3% had joint pain, and had 21.7% chest pain
- About 44% reported worsened quality of life on the EuroQol visual analog scale.
The sample cohort, assessed in a COVID-19 patient service recently established at the Fondazione Policlinico Universitario Agostino Gemelli had a mean age of 56.5 years and 37% were women. The mean length of hospital stay was 13.5 days. During their hospitalization, 72.7% of patients showed evidence of interstitial pneumonia. Noninvasive ventilation was given to 14.7% of patients and 4.9% received invasive ventilation.
The reality of lingering symptoms has led Dr. Carfi’s clinic to schedule a final “wrap-up visit” for patients after full assessment. “On that occasion the doctor prescribes anything necessary to correct the anomalies found during the full evaluation,” Dr. Carfi, a geriatrician at the Gemelli clinic, said in an interview. “These usually include vitamin supplementation and, in selected cases, a new drug prescription such as a blood thinner if necessary.”
Patients can also enroll in a training program in which breathing status is monitored.
In North America, doctors are also addressing the reality that the road to recovery can be a long and upward one, with persistent symptoms worse than those seen with acute influenza infection. “We see patients who were first diagnosed in March or April and still have symptoms in July,” said Zijian Chen, MD, an endocrinologist and medical director of Mount Sinai Health System’s Center for Post-COVID Care in New York.
“Persistent symptoms are much worse for COVID patients than flu patients. Even flu patients who spent time in the intensive care unit recover fully, and we can optimize their breathing before discharge,” Dr. Chen said in an interview.
As in the Italian study, Dr. Chen sees patients with COVID-19 who have ongoing shortness of breath, some requiring supplemental oxygen, or with persistent chest pain on exertion, blood clotting problems, poor concentration, gastrointestinal distress, and reduced muscle strength and impaired grasping power. He doesn’t rule out permanent lung damage in some. “Even asymptomatic individuals already show lung scarring on imaging,” he said.
The Mount Sinai program provides specialized interdisciplinary management that may include CT scans, endoscopy, and drugs such as respiratory medications or anticoagulants. It also offers training to combat the fatigue and deconditioning caused by the infection, symptoms that are not medically treatable but impact quality of life.
“These patients do get better, but I expect they may still have symptoms requiring monitoring after a year,” Dr. Chen said.
The study received no specific funding. Dr. Carfi and colleagues have disclosed no relevant financial relationships. Dr. Chen has disclosed no relevant financial relationships.

Steroids linked to increased hypertension in RA
Although the adverse effects of systemic glucocorticoids (GCs) are well known, their association with hypertension in rheumatoid arthritis (RA) has been unclear. Now, a large population-based study shows that the drugs are linked to a 17% overall increased risk for incident hypertension among patients with RA.
Further, when the researchers stratified participants by dose category, they found that doses higher than 7.5 mg were significantly associated with hypertension. Cumulative dosage was not tied to any clear pattern of risk.
The authors, led by Ruth E. Costello, a researcher at the Centre for Epidemiology Versus Arthritis in the Centre for Musculoskeletal Research at the University of Manchester (England) concluded that patients who are taking these drugs for the treatment of RA should be monitored for high blood pressure, which is an important but modifiable cardiovascular risk factor, and treated appropriately.
The results of Ms. Costello and colleagues’ study were published June 27 in Rheumatology.
“While fractures associated with these steroid drugs are well studied, hypertension is a side effect that seems to have been less well studied, and yet it is an important cardiovascular risk factor that can be managed,” Ms. Costello said in an interview.
To better understand the possible association, Ms. Costello and colleagues identified 17,760 patients who were newly diagnosed with RA between 1992 and 2019 and were included in the Clinical Practice Research Datalink, which represents about 7% of the U.K. population. None of the patients had hypertension at initial RA diagnosis. Slightly more than two-thirds were women (68.1%), and the mean age was 56.3 years.
Of those patients, 7,421 (41.8%) were prescribed GCs during postdiagnosis follow-up. Most patients (73%) were followed for at least 2 years.
Patients who used GCs were slightly older than never-users (mean age, 57.7 vs. 55.3 years), were predominantly women, had a history of smoking, and had more comorbidities.
The overall incidence rate (IR) of hypertension was 64.1 per 1,000 person-years (95% confidence interval, 62.5-65.7). There were 6,243 cases of incident hypertension over 97,547 person-years of follow-up.
Among those exposed to GCs, 1,321 patients developed hypertension, for an IR of 87.6 per 1,000 person-years. Among unexposed participants, the IR for hypertension was 59.7 per 1,000 person-years. In Cox proportional hazards modeling, GC use was associated with a 17% increased risk for hypertension (hazard ratio, 1.17; 95% CI, 1.10-1.24).
The researchers noted that 40% of GC users with hypertension were not prescribed an antihypertensive agent at any point during the study. “Whilst some may have been offered lifestyle advice, left untreated this has important implications in terms of addressing modifiable risk factors in an RA population already at increased risk of CV disease,” they wrote.
They noted that cardiovascular disease is a major driver of the elevated mortality risk seen among adults with RA compared with the general population and that recent treatment recommendations address management of cardiovascular risks in these patients.
“There are several routes by which GCs may promote cardiovascular disease, including hypertension, metabolic changes, diabetes, and weight gain. We don’t currently know the extent to which each of these individual mechanisms may be increasing cardiovascular disease,” said Ms. Costello.
“Glucocorticoids increase fluid retention and promote obesity and hypertension,” said Rajat S. Bhatt, MD, a rheumatologist at Prime Rheumatology and Memorial Hermann Katy Hospital in Richmond, Texas, who sees hypertension in GC users in his clinical practice. “So patients need to be monitored for these risk factors,” he said in an interview.
Although hypertension may be a significant factor in the increase in cardiovascular disease in the RA population, Dr. Bhatt said the major driver is likely the intrinsic inflammatory state caused by the disease itself. As to why the GC-hypertension connection has flown under the radar in RA, he added, “That specific link has been difficult to tease out since RA patients are often on multiple medications.”
In regard to the role of dosage, Dr. Bhatt said that hypertension risk increases with higher GC doses, as the U.K. study indicates, and usually subsides when patients stop using GCs.
“Whether the observed dose association is causal or influenced by the underlying disease severity, our results suggest we should be vigilant in patients on all doses of GC, especially higher doses,” Ms. Costello added.
In regard to using drugs that are less cardiotoxic than GCs, Dr. Bhatt said that there are clinical scenarios in which GC therapy is the best choice, so just switching to nonsteroidal drugs is no panacea. “All RA drugs have adverse side effects, and anyway, the goal of rheumatology treatment is always to get patients off corticosteroids as soon as possible,” he said.
Ms. Costello and colleagues noted that their results are consonant with earlier research, including a single-center, cross-sectional study in which less than 6 months’ use of prednisolone at a median dose of 7.5 mg was associated with hypertension. In a German registry study, among patients who received doses of less than 7.5 mg for less than 6 months, there were higher rates of self-reported elevations in blood pressure.
The findings are at odds, however, with a recent matched-cohort study, which also used data from the Clinical Practice Research Datalink. That study found no association between GC use and hypertension.
GCs have come under increasing scrutiny in regard to several diseases. A study published July 7 found that even short-term courses of a few days’ duration entail risks for serious adverse events.
Ms. Costello’s group says that an estimate of GC-related incident hypertension in RA should allow more informed treatment decisions and that their findings highlight the ongoing need to monitor for and address this risk.
The study was supported by the Centre for Epidemiology Versus Arthritis and by the National Institute for Health Research Manchester Biomedical Research Centre. Coauthor William G. Dixon, PhD, has received consultancy fees from Google and Bayer unrelated to this study. Dr. Bhatt has disclosed no relevant financial relationships.

Even a few days of steroids may be risky, new study suggests
Extended use of corticosteroids for chronic inflammatory conditions puts patients at risk for serious adverse events (AEs), including cardiovascular disease, osteoporosis, cataracts, and diabetes. Now, a growing body of evidence suggests that even short bursts of these drugs are associated with serious risks.
Most recently, a population-based study of more than 2.6 million people found that taking corticosteroids for 14 days or less was associated with a substantially greater risk for gastrointestinal (GI) bleeding, sepsis, and heart failure, particularly within the first 30 days after therapy.
In the study, Tsung-Chieh Yao, MD, PhD, a professor in the division of allergy, asthma, and rheumatology in the department of pediatrics at Chang Gung Memorial Hospital in Taoyuan, Taiwan, and colleagues used a self-controlled case series to analyze data from Taiwan’s National Health Insurance Research Database of medical claims. They compared patients’ conditions in the period from 5 to 90 days before treatment to conditions from the periods from 5 to 30 days and from 31 to 90 days after therapy.
With a median duration of 3 days of treatment, the incidence rate ratios (IRRs) were 1.80 (95% confidence interval, 1.75-1.84) for GI bleeding, 1.99 (95% CI, 1.70-2.32) for sepsis, and 2.37 (95% CI, 2.13-2.63) for heart failure.
Given the findings, physicians should weigh the benefits against the risks of rare but potentially serious consequences of these anti-inflammatory drugs, according to the authors.
“After initiating patients on oral steroid bursts, physicians should be on the lookout for these severe adverse events, particularly within the first month after initiation of steroid therapy,” Dr. Yao said in an interview.
The findings were published online July 6 in Annals of Internal Medicine.
Of the 15,859,129 adult Asians in the Taiwanese database, the study included 2,623,327 adults aged 20-64 years who received single steroid bursts (14 days or less) between Jan. 1, 2013, and Dec. 31, 2015.
Almost 60% of the indications were for skin disorders, such as eczema and urticaria, and for respiratory tract infections, such as sinusitis and acute pharyngitis. Among specialties, dermatology, otolaryngology, family practice, internal medicine, and pediatrics accounted for 88% of prescriptions.
“Our findings are important for physicians and guideline developers because short-term use of oral corticosteroids is common and the real-world safety of this approach remains unclear,” the authors wrote. They acknowledged that the database did not provide information on such potential confounders as disease severity and lifestyle factors, nor did it include children and vulnerable individuals, which may limit the generalizability of the results.
The findings echo those of a 2017 cohort study conducted by researchers at the University of Michigan in Ann Arbor. That study, by Akbar K. Waljee, MD, assistant professor of gastroenterology, University of Michigan, Ann Arbor, and colleagues, included data on more than 1.5 million privately insured U.S. adults. The researchers included somewhat longer steroid bursts of up to 30 days’ duration and found that use of the drugs was associated with a greater than fivefold increased risk for sepsis, a more than threefold increased risk for venous thromboembolism, and a nearly twofold increased risk for fracture within 30 days of starting treatment.
Furthermore, the elevated risk persisted at prednisone-equivalent doses of less than 20 mg/d (IRR, 4.02 for sepsis, 3.61 for venous thromboembolism, and 1.83 for fracture; all P < .001).
The U.S. study also found that during the 3-year period from 2012 to 2014, more than 20% of patients were prescribed short-term oral corticosteroids.
“Both studies indicate that these short-term regimens are more common in the real world than was previously thought and are not risk free,” Dr. Yao said.
Recognition that corticosteroids are associated with adverse events has been building for decades, according to the authors of an editorial that accompanies the new study.
“However, we commonly use short corticosteroid ‘bursts’ for minor ailments despite a lack of evidence for meaningful benefit. We are now learning that bursts as short as 3 days may increase risk for serious AEs, even in young and healthy people,” wrote editorialists Beth I. Wallace, MD, of the Center for Clinical Management Research at the VA Ann Arbor Healthcare System and the Institute for Healthcare Policy and Innovation at Michigan Medicine, Ann Arbor, and Dr. Waljee, who led the 2017 study.
Dr. Wallace and Dr. Waljee drew parallels between corticosteroid bursts and other short-term regimens, such as of antibiotics and opiates, in which prescriber preference and sometimes patient pressure play a role. “All of these treatments have well-defined indications but can cause net harm when used. We can thus conceive of a corticosteroid stewardship model of targeted interventions that aims to reduce inappropriate prescribing,” they wrote.
In an interview, Dr. Wallace, a rheumatologist who prescribes oral steroids fairly frequently, noted that the Taiwan study is the first to investigate steroid bursts. “Up till now, these very short courses have flown under the radar. Clinicians very commonly prescribe short courses to help relieve symptoms of self-limited conditions like bronchitis, and we assume that because the exposure duration is short, the risks are low, especially for patients who are otherwise healthy.”
She warned that the data in the current study indicate that these short bursts – even at the lower end of the 1- to 2-week courses American physicians prescribe most often – carry small but real increases in risk for serious AEs. “And these increases were seen in young, healthy people, not just in people with preexisting conditions,” she said. “So, we might need to start thinking harder about how we are prescribing even these very short courses of steroids and try to use steroids only when their meaningful benefits really outweigh the risk.”
She noted that a patient with a chronic inflammatory condition such as rheumatoid arthritis may benefit substantially from short-term steroids to treat a disease flare. In that specific case, the benefits of short-term steroids may outweigh the risks, Dr. Wallace said.
But not everyone thinks a new strategy is needed. For Whitney A. High, MD, associate professor of dermatology and pathology at the University of Colorado at Denver, Aurora, the overprescribing of short-term corticosteroids is not a problem, and dermatologists are already exercising caution.
“I only prescribe these drugs short term to, at a guess, about 1 in 40 patients and only when a patient is miserable and quality of life is being seriously affected,” he said in an interview. “And that’s something that can’t be measured in a database study like the one from Taiwan but only in a risk-benefit analysis,” he said.
Furthermore, dermatologists have other drugs and technologies in their armamentarium, including topical steroids with occlusion or with wet wraps, phototherapy, phosphodiesterase inhibitors, calcipotriene, methotrexate and other immunosuppressive agents, and biologics. “In fact, many of these agents are specifically referred to as steroid-sparing,” Dr. High said.
Nor does he experience much pressure from patients to prescribe these drugs. “While occasionally I may encounter a patient who places pressure on me for oral steroids, it’s probably not nearly as frequently as providers in other fields are pressured to prescribe antibiotics or narcotics,” he said.
According to the Taiwanese researchers, the next step is to conduct more studies, including clinical trials, to determine optimal use of corticosteroids by monitoring adverse events. In the meantime, for practitioners such as Dr. Wallace and Dr. High, there is ample evidence from several recent studies of the harms of short-term corticosteroids, whereas the benefits for patients with self-limiting conditions remain uncertain. “This and other studies like it quite appropriately remind providers to avoid oral steroids when they’re not necessary and to seek alternatives where possible,” Dr. High said.
The study was supported by the National Health Research Institutes of Taiwan, the Ministry of Science and Technology of Taiwan, the Chang Gung Medical Foundation, and the Eunice Kennedy Shriver National Institute of Child Health and Human Development of the National Institutes of Health (NIH).

Extended use of corticosteroids for chronic inflammatory conditions puts patients at risk for serious adverse events (AEs), including cardiovascular disease, osteoporosis, cataracts, and diabetes. Now, a growing body of evidence suggests that even short bursts of these drugs are associated with serious risks.
Most recently, a population-based study of more than 2.6 million people found that taking corticosteroids for 14 days or less was associated with a substantially greater risk for gastrointestinal (GI) bleeding, sepsis, and heart failure, particularly within the first 30 days after therapy.
In the study, Tsung-Chieh Yao, MD, PhD, a professor in the division of allergy, asthma, and rheumatology in the department of pediatrics at Chang Gung Memorial Hospital in Taoyuan, Taiwan, and colleagues used a self-controlled case series to analyze data from Taiwan’s National Health Insurance Research Database of medical claims. They compared patients’ conditions in the period from 5 to 90 days before treatment to conditions from the periods from 5 to 30 days and from 31 to 90 days after therapy.
With a median duration of 3 days of treatment, the incidence rate ratios (IRRs) were 1.80 (95% confidence interval, 1.75-1.84) for GI bleeding, 1.99 (95% CI, 1.70-2.32) for sepsis, and 2.37 (95% CI, 2.13-2.63) for heart failure.
Given the findings, physicians should weigh the benefits against the risks of rare but potentially serious consequences of these anti-inflammatory drugs, according to the authors.
“After initiating patients on oral steroid bursts, physicians should be on the lookout for these severe adverse events, particularly within the first month after initiation of steroid therapy,” Dr. Yao said in an interview.
The findings were published online July 6 in Annals of Internal Medicine.
Of the 15,859,129 adult Asians in the Taiwanese database, the study included 2,623,327 adults aged 20-64 years who received single steroid bursts (14 days or less) between Jan. 1, 2013, and Dec. 31, 2015.
Almost 60% of the indications were for skin disorders, such as eczema and urticaria, and for respiratory tract infections, such as sinusitis and acute pharyngitis. Among specialties, dermatology, otolaryngology, family practice, internal medicine, and pediatrics accounted for 88% of prescriptions.
“Our findings are important for physicians and guideline developers because short-term use of oral corticosteroids is common and the real-world safety of this approach remains unclear,” the authors wrote. They acknowledged that the database did not provide information on such potential confounders as disease severity and lifestyle factors, nor did it include children and vulnerable individuals, which may limit the generalizability of the results.
The findings echo those of a 2017 cohort study conducted by researchers at the University of Michigan in Ann Arbor. That study, by Akbar K. Waljee, MD, assistant professor of gastroenterology, University of Michigan, Ann Arbor, and colleagues, included data on more than 1.5 million privately insured U.S. adults.

Pregnant women at greater risk for severe COVID-19, CDC says
Pregnant women may be at increased risk for severe COVID-19 illness, according to a new report published online June 26 in Morbidity and Mortality Weekly Report.
Among reproductive-aged women (15-44 years) infected with SARS-CoV-2, Pregnant women were 5.4 times more likely to be hospitalized, 1.5 times more likely to be admitted to the ICU, and 1.7 times more likely to need mechanical ventilation, after adjustment for age, underlying conditions, and race/ethnicity.
Furthermore, Hispanic and non-Hispanic black pregnant women appear to be disproportionately impacted by the infection.
Sascha Ellington, PhD, of the Centers for Disease Control and Prevention’s COVID-19 Response Pregnancy and Infant Linked Outcomes Team, and colleagues said that preventing COVID-19 infection in pregnant women should be a priority and any potential barriers to compliance with preventive measures need to be removed.
“During pregnancy, women experience immunologic and physiologic changes that could increase their risk for more severe illness from respiratory infections,” they wrote.
As of June 7, a total of 8,207 cases of COVID-19 in pregnant women were reported to the CDC, approximately 9% of COVID-19 cases among reproductive-aged women with known pregnancy status. The authors compared outcomes in these pregnant patients with those in 83,205 nonpregnant women with COVID-19. There was a substantially greater proportion of hospital admissions among pregnant patients (2,587; 31.5%) compared with nonpregnant patients (4,840; 5.8%) with COVID-19.
The authors cautioned that there were no data to differentiate between hospitalizations for COVID-19–related problems as opposed to those arising from pregnancy, including delivery.
For other severity measures, ICU admissions were reported for 1.5% of pregnant women compared with 0.9% for their nonpregnant counterparts, whereas mechanical ventilation was required for 0.5% compared with 0.3%, respectively. Mortality was identical, affecting 0.2% in both groups, with 16 deaths in pregnant patients with COVID-19 and 208 in nonpregnant patients.
Age had an impact as well, with hospitalization more frequent among those aged 35-44 years than among those aged 15-24, regardless of pregnancy status. When stratified by race/ethnicity, ICU admission was most frequently reported among pregnant women who were of non-Hispanic Asian lineage: 3.5% compared with 1.5% in all pregnant women.
Among pregnant women with laboratory-confirmed SARS-CoV-2 infection reporting race/ethnicity, 46% were Hispanic, 22% were black, and 23% were white, whereas among women who gave birth in 2019, 24% were Hispanic, 15% were black, and 51% were white. “Although data on race/ethnicity were missing for 20% of pregnant women in this study, these findings suggest that pregnant women who are Hispanic and black might be disproportionately affected by SARS-CoV-2 infection during pregnancy,” the authors wrote.
They noted that in a recent meta-analysis of influenza, pregnancy was similarly associated with a sevenfold risk for hospitalization, but a lower risk for ICU admission and no increased risk for death. A recent study suggested that COVID-19 severity during pregnancy may be lower than in other respiratory infections such as H1N1.
ACOG responds
In a response to the CDC findings, the American College of Obstetricians and Gynecologists (ACOG) advises calm, noting that the risk of needing the severity-associated interventions in the CDC report remains low and pregnant COVID-19 patients do not appear to have a greater risk for mortality.
Nevertheless, ACOG is reviewing all its COVID-19–related clinical and patient materials and “will make any necessary revisions to recommendations.”
In the meantime, the college advises clinicians to alert patients to the potential increased risk for severe COVID-19 illness during pregnancy. They should also stress to pregnant women and their families the need for precautions to prevent infection, paying particular attention to measures to protect those with greater occupational exposure to the virus.
ACOG also criticized the exclusion of pregnant and lactating women from clinical trials of potential coronavirus vaccines, noting that the new CDC findings underscore the importance of prioritizing pregnant patients to receive coronavirus vaccination when it becomes available.
“ACOG again urges the federal government to use its resources to ensure the safe inclusion of pregnant and lactating patients, including patients of color, in trials for vaccines and therapeutics to ensure that all populations are included in the search for ways to prevent and treat COVID-19,” the statement reads.
The CDC authors said that their report also highlights the need for more complete data to fully understand the risk for severe illness in pregnant women. To address these gaps, the CDC is collaborating with health departments in COVID-19 pregnancy surveillance for the reporting of outcomes in pregnant women with laboratory-confirmed SARS-CoV-2 infection.

In a response to the CDC findings, the American College of Obstetricians and Gynecologists (ACOG) advises calm, noting that the risk of needing the severity-associated interventions in the CDC report remains low and pregnant COVID-19 patients do not appear to have a greater risk for mortality.
Nevertheless, ACOG is reviewing all its COVID-19–related clinical and patient materials and “will make any necessary revisions to recommendations.”
In the meantime, the college advises clinicians to alert patients to the potential increased risk for severe COVID-19 illness during pregnancy. They should also stress to pregnant women and their families the need for precautions to prevent infection, paying particular attention to measures to protect those with greater occupational exposure to the virus.
ACOG also criticized the exclusion of pregnant and lactating women from clinical trials of potential coronavirus vaccines, noting that the new CDC findings underscore the importance of prioritizing pregnant patients to receive coronavirus vaccination when it becomes available.
“ACOG again urges the federal government to use its resources to ensure the safe inclusion of pregnant and lactating patients, including patients of color, in trials for vaccines and therapeutics to ensure that all populations are included in the search for ways to prevent and treat COVID-19,” the statement reads.
The CDC authors said that their report also highlights the need for more complete data to fully understand the risk for severe illness in pregnant women. To address these gaps, the CDC is collaborating with health departments in COVID-19 pregnancy surveillance for the reporting of outcomes in pregnant women with laboratory-confirmed SARS-CoV-2 infection.
