HIV patients show accelerated aging related to altered sleep

Accelerated brain aging among HIV-infected adults might be caused in part by altered deep sleep patterns, new research suggests.

Using a measure known as the brain age index (BAI) – a machine-learning model that measures deviations in brain activity during sleep relative to healthy individuals – investigators identified 34 sleep electroencephalogram features that were significantly altered by HIV infection. The most notable of these was the decline in slow-wave activity during non-REM sleep, which has been previously associated with MRI markers of brain aging in healthy adults.

“One of the functions of slow-wave sleep appears to be its association with the glymphatic system, which clears [metabolic] waste products and supports memory consolidation,” study coauthor Brandon Westover, MD, PhD, associate professor of neurology at Massachusetts General Hospital/Harvard Medical School, Boston, said in an interview. “It’s also believed to be associated with an accelerated risk for dementia and other cognitive issues.”

Previous work conducted at Johns Hopkins and other institutions confirm Dr. Westerson’s hypothesis. Charlene Gamaldo, MD, medical director of Johns Hopkins Sleep Disorders Center in Baltimore, pointed to other study findings in patients with neurodegenerative disease that have shown a link between predominant habitual sleep positions and dementia, potentially driven by inefficient glymphatic transport. Dr. Gamaldo was not involved in the current study.
 

Threefold acceleration vs. healthy volunteers

“We’ve been grappling with whether people with HIV on ART experience accelerated aging or accentuated aging,” coauthor Shibani Mukerji, MD, PhD, associate director of the neuroinfectious diseases unit at Massachusetts General, said in an interview. “We have yet to have biomarkers to address this question, and most of the tools are limited to invasive or expensive diagnostics. “In general, sleep and its influence on health have been understudied in the HIV population.”

To address this question, the researchers retrospectively examined a Massachusetts General Hospital database of diagnostic sleep study participants from 2008 to 2018, identifying 3,155 healthy, HIV-negative control subjects and 43 HIV-positive participants. Thirty-four (79%) of the HIV-positive participants were men, 30 (70%) were White, and 38 (93%) were virally suppressed at the time of their sleep study. Four patients were taking efavirenz, 13 were taking an integrase strand transfer inhibitor, and all were adherent to antiretroviral therapy (ART) at the time of their sleep study.

None of the HIV-positive participants had a history of secondary brain infection or brain tumor, although one patient had recovered fully from a previous HIV-associated encephalitis.

The study findings, which were published online March 30, 2021, in Sleep, first showed that HIV-positive participants had an average BAI of 3.19 years (standard error of the mean,1.43 years), compared with the control participants, who had an average BAI of –0.16 (SEM, 0.18 years).

These findings held after adjustment for potential confounders (age, sex, race, tobacco use disorder, and alcohol use disorder), yielding a total effect of HIV on BAI of 3.35 years (P < .01).

“Despite being well controlled on ART, HIV-positive individuals who had participated in the sleep studies still had elevated brain age,” said Dr. Westover. “We didn’t have enough information to determine the pathways by which HIV increases the BAI, but chronic inflammation appears to be an important factor.”

The findings also demonstrated that comorbidities accounted for roughly a quarter of the effect of HIV on BAI. However, the lack of statistical significance (in part because of the limited sample size) precluded the ability to determine if treating or preventing them might influence the degree to which HIV affects BAI and, in turn, cognitive decline.
 

 

 

HIV, sleep EEG, and brain aging

To estimate the effect of HIV on specific EEG features, the investigators again evaluated the total effect, this time replacing BAI with individual sleep EEG as the primary outcome. Among the 34 EEG features significantly altered by HIV, none were observed in the wake state and three were altered in REM (each associated with reduced delta band power). The rest were distributed in non-REM sleep, most notably in the deepest phase, corresponding to relative reductions in delta wave power.

The study findings build on the investigators’ previous research, which demonstrated an association between greater mean BAI and dementia, psychotic disorders, and anxiety/mood disorders in HIV-negative subjects, all of which correlated to attenuated slow-wave sleep.

More research is needed to determine if BAI, as it relates to sleep EEG, can effectively track the risk for cognitive decline among HIV-positive people, and if certain confounders might attenuate or accelerate this risk.

“While our team has not specifically looked at BAI, the findings in this study seem perfectly in line with what we have found with our own research,” Dr. Gamaldo said in an interview. “Not only have we observed a robust association between minimal cognitive deficits and patients’ sleep complaints (despite being virally controlled), but also, the potential value of measuring the architectural sleep features by ambulatory EEG to identify HIV patients’ vulnerability to cognitive decline.”

“BAI is a physiologic, easily repeatable measurement that can be used to track if an intervention is having a good effect,” Dr. Westover said.

Dr. Mukerji concurred, adding that “having a tool that can be used in resource-challenged settings and also be incorporated into longitudinal studies in a patient population with substantial age-related comorbidities, like HIV, would be really helpful.”

Dr. Westover and Dr. Mukerji disclosed no relevant financial relationships. Dr. Gamaldo is a consultant for Jazz Pharmaceuticals, and has received author royalties from UpToDate and honoraria from Medscape CME for content contribution.

Overshadowed by COVID, HIV Epidemic Rages On

Article Type

The HIV epidemic gathers strength due, in part, to the economic and health complications exposed by COVID-19.

How many epidemics can one country contain? Nearly all of our national attention has been focused on the COVID-19 epidemic but, lest we forget, there’s still another one to be reckoned with: the HIV epidemic is still going strong. In fact, it’s gathering strength, in part, because of the economic and health devastation wrought by COVID.

                Over nearly 4 decades, the epidemiology of HIV has changed, according to The Lancet’s HIV in the USA series. Current data, the report says, “illustrate an epidemic defined by stark health inequities that largely fall along lines of disadvantages in economic opportunity and social capital.” Moreover, the US, the authors say, “continues to lag behind other G-7 nations when it comes to controlling its HIV epidemic and is the only high-income country among the top 10 countries most affected by HIV.”

                The 6-paper series’ release comes 2 years after the launch of the US Department of Health and Human Services’ (HHS) announcement of its goal to reduce HIV transmissions by at least 90% by 2030.

                The authors analyzed publicly available HIV surveillance and census data to describe current prevalence and new HIV diagnoses by region, race, ethnicity, and age, as well as trends in those categories over time. They also reviewed literature to “explore the reasons” for the distribution of cases and important disparities in prevalence. Among other things, the researchers found “pronounced” racial, sexual, and gender disparities, “substantial” gaps in domestic program funding, and a “patchwork healthcare system” that limited access to treatment and prevention services.

                Although when it began, the HIV epidemic was focused largely on the bicoastal big cities, mainly New York and San Francisco, in recent years the South has been hit particularly hard, with 52% of new HIV transmissions in 2018, despite representing only 37% of the US population. Six Southern states (Florida, Georgia, Louisiana, Maryland, Mississippi, and Tennessee) and the District of Columbia had the highest annual HIV diagnosis rates between 2010 and 2018, likely reflecting the higher burden of infection among black residents: In 2018, 38% of all new HIV diagnoses among men who have sex with men (MSM) were in the black population, and 63% of those were in the South.

                The South’s HIV problem is intensified by disparities, the report says, that are probably driven by the restricted expansion of Medicaid, health care provider shortages, low health literacy, and stigma. The South also has the lowest number of pre-exposure prophylaxis (PrEP) users per new HIV diagnosis, in part because of the longer distances to PrEP services relative to other regions. More than half of MSM who live at least 60 minutes away from PrEP services live in the South. While HIV in the rural South largely is due to sexual transmission, the researchers note, the largest clusters of the concurrent opioid epidemic have been detected in rural and periurban counties of West Virginia and Indiana.

                Identifying HIV transmission clusters and outbreaks has traditionally been challenging for several reasons, the researchers say, including delays between infection and diagnosis, mobility of populations, and limitations in tracing sex and drug partners. They suggest that analysis of molecular data can help overcome some of those barriers, making it possible to identify clusters of ongoing HIV transmission.

                The report also recommends other approaches to better understand and respond to ongoing HIV infections, such as mapping and data visualization, telemedicine, and automated data systems to facilitate linkage to care. However, the authors add, gaps in data and data systems remain that prevent full understanding of some key impacts of the epidemic. But any interventions to promote HIV prevention and treatment adherence, the authors suggested, should take a multifaceted approach and address the whole individual.

                Chris Beyrer, MD, MPH, investigator at the Johns Hopkins Bloomberg School of Public Health, Baltimore, and a lead author on the series, says, “We have incredible tools to prevent and treat HIV, but people may not fully utilize them if they are facing personal or structural issues that pose more immediate hardship, like substance use and mental health disorders. You may struggle to take a daily medication if you are facing food insecurity or cannot find affordable treatment for your substance use disorder.”

                Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, and now also Chief Medical Advisor to President Biden, says, “To end the HIV epidemic, we must continue to develop and deploy novel HIV treatment and prevention strategies suited to the different needs and preferences of diverse populations disproportionately affected by HIV. It is also essential that HIV health services continue during the COVID-19 pandemic.”

Liposomal doxorubicin (Dox) plus pomalidomide (Pom) was safe and active in heavily pretreated patients with Kaposi sarcoma, according to results from a phase 1/2 trial.

“The results of our phase 1/2 study suggest pomalidomide and liposomal doxorubicin is safe with evidence of activity among patients with Kaposi sarcoma,” said investigator Ramya Ramaswami, MBBS, MPH, of the HIV & AIDS malignancy branch at the National Cancer Institute. The results were presented at the Conference on Retroviruses and Opportunistic Infections.

The researchers evaluated the safety and tolerability of Pom/Dox in two groups of patients with Kaposi sarcoma: group 1 included patients with Kaposi sarcoma alone and group 2 included patients with Kaposi sarcoma–associated herpesvirus and concurrent multicentric Castleman disease (KSHV-MCD) and KSHV inflammatory cytokine syndrome (KICS).

“Kaposi sarcoma can be challenging to treat when it co-occurs with KSHV-MCD or KICS, resulting in high mortality rates,” Dr. Ramaswami explained.

Study participants received IV liposomal Dox at 20 mg/m2 on day 1 of a 28-day cycle, in addition to oral Pom once daily on days 1-21 at three escalating dose levels (2 mg, 3 mg, or 4 mg, respectively) using a standard 3 + 3 design until plateau of response, progression, dose-limiting toxicities (DLTs) or patient preference. Some eligibility criteria differed between groups 1 and 2. Participants in group 1 were required to be on antiretroviral therapy for at least 1 month and had a performance status of 2 or less, while those in group 2 had a performance status of 3 or less and could be antiretroviral therapy naive.

All participants received oral aspirin thromboprophylaxis (81 mg daily) and could have received prior Kaposi sarcoma therapy.

With respect to outcomes, Kaposi sarcoma responses were assessed using the modified AIDS Clinical Trial Group criteria and KICS and KSHV-MCD responses were evaluated using an NCI clinical benefit criteria.

Overall, 34 cisgender men were enrolled in the study: 21 (62%) in group 1 and 13 (38%) in group 2. All participants had severe (T1) Kaposi sarcoma; 32 (94%) participants were HIV-infected and 22 (65%) had prior chemotherapy for Kaposi sarcoma.

While the HIV viral load was largely controlled in both groups, the CD4 count differed, with median CD4 counts of 286 and 92 cells/mcL in groups 1 and 2, respectively.

With respect to safety, no DLTs were observed in group 1. As a result, 12 participants were treated at the maximum tolerated dose (MTD) of 4 mg of Pom. However, two DLTs (grade 3 rash and pharyngeal edema) were observed in group 2 at the 3 mg dose level.

A median of six cycles were administered for all participants and the most common grade 3/4 toxicity was neutropenia; nine patients with grade 3 neutropenia required dose reduction and three patients had febrile neutropenia requiring hospitalization. Other Pom-related adverse events were rash, constipation, and fatigue.

Among evaluable participants receiving two or more cycles, 17 (81%) patients in group 1 had a response (95% confidence interval, 58-95%; 16 partial response and 1 complete response) and 5 (50%) patients in group 2 had a response (95% CI, 19-81%; 4 PR and 1 CR).

“Our waterfall plots indicated that the vast majority of patients in group 1 had a positive change in nodular lesions at baseline,” Dr. Ramaswami said. “Participants in group 2 showed some decrease in nodular lesions, but this was usually temporary.”

Among seven participants with KICS responses, four participants (57%) experienced a CR or PR in symptoms and lab abnormalities associated with KICS; three of six participants (50%) with KSHV-MCD responses experienced a PR as per response criteria.

“While activity was noted, the combination was less well tolerated in patients with Kaposi sarcoma and concurrent KSHV-MCD or KICS,” Dr. Ramaswami said.

During a live discussion, Ronald T. Mitsuyasu, MD, of the University of California, Los Angeles, asked Dr. Ramaswami about the use of liposomal doxorubicin alone in patients with Kaposi sarcoma and concurrent KSHV-MCD or KICS.

While there is currently no data on the use of doxorubicin alone in this population, Dr. Ramaswami noted that she was more confident administering Pom/Dox combination therapy for these patients.

Dr. Ramaswami disclosed financial relationships with the National Cancer Institute, Celgene/Bristol-Myers Squibb, EMD Serono, Merck, CTI Biopharma, and Janssen. The study was funded by a cooperative research and drug development agreement between the National Cancer Institute and Celgene/BMS, EMD Serono, Merck, CTI Biopharma, and Janssen.

“The results of our phase 1/2 study suggest pomalidomide and liposomal doxorubicin is safe with evidence of activity among patients with Kaposi sarcoma,” said investigator Ramya Ramaswami, MBBS, MPH, of the HIV & AIDS malignancy branch at the National Cancer Institute. The results were presented at the Conference on Retroviruses and Opportunistic Infections.

The researchers evaluated the safety and tolerability of Pom/Dox in two groups of patients with Kaposi sarcoma: group 1 included patients with Kaposi sarcoma alone and group 2 included patients with Kaposi sarcoma–associated herpesvirus and concurrent multicentric Castleman disease (KSHV-MCD) and KSHV inflammatory cytokine syndrome (KICS).

“Kaposi sarcoma can be challenging to treat when it co-occurs with KSHV-MCD or KICS, resulting in high mortality rates,” Dr. Ramaswami explained.

Study participants received IV liposomal Dox at 20 mg/m2 on day 1 of a 28-day cycle, in addition to oral Pom once daily on days 1-21 at three escalating dose levels (2 mg, 3 mg, or 4 mg, respectively) using a standard 3 + 3 design until plateau of response, progression, dose-limiting toxicities (DLTs) or patient preference. Some eligibility criteria differed between groups 1 and 2. Participants in group 1 were required to be on antiretroviral therapy for at least 1 month and had a performance status of 2 or less, while those in group 2 had a performance status of 3 or less and could be antiretroviral therapy naive.

All participants received oral aspirin thromboprophylaxis (81 mg daily) and could have received prior Kaposi sarcoma therapy.

With respect to outcomes, Kaposi sarcoma responses were assessed using the modified AIDS Clinical Trial Group criteria and KICS and KSHV-MCD responses were evaluated using an NCI clinical benefit criteria.

Vaginal pH may predict CIN 2 progression in HIV-positive women

Article Type
Changed
Fri, 03/12/2021 - 09:38

Elevated vaginal pH at the time of cervical intraepithelial neoplasia 2 diagnosis may be a useful marker of CIN 2 persistence/progression, as well as the rate of persistence/progression in HIV-positive women, new research suggests.

“We analyzed data from the Women’s Interagency HIV Study [WIHS], an observational, longitudinal cohort of women with and without HIV to determine factors that may influence CIN 2 natural history,” said Kate Michel, PhD, MPH, of Georgetown University, Washington. She presented the results at the Conference on Retroviruses and Opportunistic Infections.

As previous data have shown a high incidence of CIN 2 progression among women with HIV, the researchers evaluated the role of human papillomavirus (HPV) type, local immune response, and markers of the cervicovaginal microbiome on the risk of CIN 2 persistence/progression.

Within the cohort, follow-up visits occur every 6 months, and clinical data is collected via questionnaires, physical and gynecologic exams, and biological samples. As no specific treatment is offered in the WIHS, treatment for cervical abnormalities is abstracted from medical records.

In the present study, Dr. Michel and colleagues selected up to four banked cervicovaginal lavage (CVL) samples per woman, with the first sample selected 6-12 months prior to CIN 2 diagnosis, the second at CIN 2 diagnosis, the third between CIN 2 diagnosis and outcome, and the fourth at the outcome visit.

The investigators performed HPV typing and muiltiplex immune mediator testing on each CVL sample. Lab results from WIHS core testing were also extracted, including plasma CD4+ T-cell count and HIV viral load, as well as vaginal pH and Nugent’s score.

Study outcomes included persistence/progression and regression, defined as a subsequent CIN 2 or CIN 3 diagnosis and subsequent CIN 1 or normal diagnosis, respectively. Logistic regression models were used to determine CIN 2 regression versus persistence/progression.
 

Results

A total of 337 samples were obtained and 94 women were included in the analysis. Key demographic and behavioral factor were similar at CIN 2 diagnosis.

The majority of participants were African American (53.2%) and on antiretroviral therapy (66.0%). The most prevalent high-risk types were HPV-58 (18.4%) and HPV-16 (17.5%).

After a median 12.5 years of follow-up, 33 participants (35.1%) with incident CIN 2 had a subsequent CIN 2/CIN 3 diagnosis and those who regressed had a higher CD4 T-cell count at CIN 2 diagnosis (P = .02).

Each subsequent high-risk HPV type identified at the pre–CIN 2 visit was associated with higher odds of CIN2 persistence/progression (odds ratio, 2.27; 95% confidence interval, 1.15-4.50).

Bacterial vaginosis (adjusted OR, 5.08; 95% CI, 1.30-19.94) and vaginal pH (aOR, 2.27; 95% CI, 1.15-4.50) at the CIN 2 diagnosis visit were each associated with increased odds of CIN 2 persistence/progression.

Vaginal pH greater than 4.5 at CIN 2 diagnosis was also associated with unadjusted time to CIN 2 persistence/progression (log rank P = .002) and an increased rate of CIN 2 persistence/progression (adjusted hazard ratio, 3.37; 95% CI, 1.26-8.99).

Furthermore, among participants who did not receive CIN 2 treatment, vaginal pH remained associated with greater odds of CIN 2 persistence/progression (OR, 2.46; 95% CI, 1.19-5.13). Cervicovaginal immune mediator levels were not associated with CIN 2 persistence/progression.

“The most striking finding from this work was that vaginal pH was associated with higher odds of, quicker time to, and increased hazard of CIN 2 persistence/progression,” Dr. Michel said. “We postulate this effect is mediated by the cervical microbiome, but more work is needed to establish the exact mechanism.”

“It would be interesting to test whether this association might be explained by different vaginal cleaning techniques, such as douching,” said moderator Ronald T. Mitsuyasu, MD, of the University of California, Los Angeles.

“We’re currently working on an analysis of cervicovaginal bacterial species to explore the microbiome in more detail,” Dr. Michel concluded.

Dr. Michel disclosed no conflicts of interest. The study was supported by multiple sources, including the National Institute of Allergy and Infectious Diseases, the National Cancer Institute, and the Georgetown-Howard Universities Center for Clinical and Translational Science.

The vanguard of HIV care: Don’t forget this screening

Article Type
Changed
Mon, 03/15/2021 - 10:22

HIV-positive patients who are adherent with antiretroviral medications are achieving undetectable or very low levels of HIV viremia and living longer. In response, clinical care is continually adapting to the dramatically altered natural history of disease.

Today, the cutting edge of clinical care overlaps with primary care. The clinical vanguard addresses the medical vulnerabilities of patients with HIV, seeking to eliminate preventable morbidity and premature death. Among this clinical vanguard is the screening for and prevention of anal cancer. With the increased longevity of people living with HIV and the nearly universal exposure to human papillomavirus (HPV), there is now potential for progression to mucosal cellular dysplasia and eventual malignancy.

We know that prevention is possible because of the example of cervical cancer, the etiology of which is exposure to oncogenic serotypes of HPV (16 and 18 are most common). Screenings for cervical cancer (regular clinical examinations and Pap smears) and treatments to eliminate high-grade dysplasia have decreased the incidence rate by over 50% since the 1970s. Vaccination against HPV has been available since 2006 and offers the prospect of preventing HPV-associated malignancies, including head and neck cancer, in future decades.

However, rates of anal cancer are increasing. The CDC estimates that about 4,700 new cases of HPV-associated anal cancers are diagnosed in women and about 2,300 are diagnosed in men each year in the United States. Anal cancer rates in individuals with HIV have increased in the era of effective antiretrovirals and greater longevity. The highest rates, at 95 per 100,000, are in HIV-positive men who have sex with men. Very similar rates were noted in a more recent study that found increased risk with advancing age and in those with an AIDS diagnosis.
 

All patients with HIV should be screened

The New York State AIDS Institute Clinical Guidelines Program recommends screening for anal dysplasia in all patients with HIV. A proactive approach similar to cervical cancer screening is appropriate and includes measures easily implemented by all clinicians.

  • History: Assess for rectal symptoms, anal pain, discharge, and lumps.
  • Physical exam: Assess for presence of perianal lesions; perform a thorough digital rectal exam.
  • Anal Pap test for anal cytology: Insert a Dacron swab moistened with tap water about 3 inches into the anal canal, applying pressure to lateral anal walls and rotating the swab. Then remove and place the swab into liquid cytology solution, shake vigorously for a full 30 seconds, and assess for any dysplasia (high-grade squamous intraepithelial lesion, low-grade intraepithelial lesion, atypical squamous cells of undetermined significance), which would warrant further evaluation by high-resolution anoscopy (HRA).

High-resolution anoscopy

HRA for anal dysplasia corresponds to colposcopy for cervical dysplasia. The ability to treat and eliminate high-risk precursor lesions interrupts the progression to malignancy. The efficacy of this strategy is being evaluated in a National Institutes of Health prospective trial called the Anchor Study. The epidemiology of HPV; the clinical horror of witnessing the painful, preventable deaths of young patients with well-controlled HIV caused by anal cancer; and the example of controlling cervical cancer have motivated my practice to assure comprehensive care for our patients.

Unfortunately, establishing HRA in one’s practice is challenging. Barriers to practice include the expense of required equipment and the absence of consensus on specific products. In addition, hands-on precepting to ease newcomers to competence is not generally available. Considerable skill is required for complete visualization of the anal transformative zone in the folds of the anal canal, and recognizing high-risk lesions requires study and accumulated experience. The International Anal Neoplasia Society is a useful resource that also offers a training course. We are invited to train ourselves, and to rely on the eventual feedback of biopsy results and the forbearance of our early patients.

The expanding scope of our medical practices must shift to meet the evolving needs of the growing population of virologically suppressed patients who are living longer. HIV care involves curing life-threatening opportunistic infections, encouraging antiretroviral adherence, and providing comprehensive care – which now includes preventing anal cancer.

  • Physical exam: Assess for presence of perianal lesions; perform a thorough digital rectal exam.
  • Anal Pap test for anal cytology: Insert a Dacron swab moistened with tap water about 3 inches into the anal canal, applying pressure to lateral anal walls and rotating the swab. Then remove and place the swab into liquid cytology solution, shake vigorously for a full 30 seconds, and assess for any dysplasia (high-grade squamous intraepithelial lesion, low-grade intraepithelial lesion, atypical squamous cells of undetermined significance), which would warrant further evaluation by high-resolution anoscopy (HRA).

High-resolution anoscopy

HRA for anal dysplasia corresponds to colposcopy for cervical dysplasia. The ability to treat and eliminate high-risk precursor lesions interrupts the progression to malignancy. The efficacy of this strategy is being evaluated in a National Institutes of Health prospective trial called the Anchor Study. The epidemiology of HPV; the clinical horror of witnessing the painful, preventable deaths of young patients with well-controlled HIV caused by anal cancer; and the example of controlling cervical cancer have motivated my practice to assure comprehensive care for our patients.

Unfortunately, establishing HRA in one’s practice is challenging. Barriers to practice include the expense of required equipment and the absence of consensus on specific products. In addition, hands-on precepting to ease newcomers to competence is not generally available. Considerable skill is required for complete visualization of the anal transformative zone in the folds of the anal canal, and recognizing high-risk lesions requires study and accumulated experience. The International Anal Neoplasia Society is a useful resource that also offers a training course. We are invited to train ourselves, and to rely on the eventual feedback of biopsy results and the forbearance of our early patients.

The expanding scope of our medical practices must shift to meet the evolving needs of the growing population of virologically suppressed patients who are living longer. HIV care involves curing life-threatening opportunistic infections, encouraging antiretroviral adherence, and providing comprehensive care – which now includes preventing anal cancer.

HIV-positive patients who are adherent with antiretroviral medications are achieving undetectable or very low levels of HIV viremia and living longer. In response, clinical care is continually adapting to the dramatically altered natural history of disease.

Today, the cutting edge of clinical care overlaps with primary care. The clinical vanguard addresses the medical vulnerabilities of patients with HIV, seeking to eliminate preventable morbidity and premature death. Among this clinical vanguard is the screening for and prevention of anal cancer. With the increased longevity of people living with HIV and the nearly universal exposure to human papillomavirus (HPV), there is now potential for progression to mucosal cellular dysplasia and eventual malignancy.

We know that prevention is possible because of the example of cervical cancer, the etiology of which is exposure to oncogenic serotypes of HPV (16 and 18 are most common). Screenings for cervical cancer (regular clinical examinations and Pap smears) and treatments to eliminate high-grade dysplasia have decreased the incidence rate by over 50% since the 1970s. Vaccination against HPV has been available since 2006 and offers the prospect of preventing HPV-associated malignancies, including head and neck cancer, in future decades.

However, rates of anal cancer are increasing. The CDC estimates that about 4,700 new cases of HPV-associated anal cancers are diagnosed in women and about 2,300 are diagnosed in men each year in the United States. Anal cancer rates in individuals with HIV have increased in the era of effective antiretrovirals and greater longevity. The highest rates, at 95 per 100,000, are in HIV-positive men who have sex with men. Very similar rates were noted in a more recent study that found increased risk with advancing age and in those with an AIDS diagnosis.

Thu, 03/11/2021 - 16:24

Any level of hepatitis B virus (HBV) viremia was associated with increased hepatocellular carcinoma (HCC) risk in adults with HIV/HBV coinfection, according to new research presented at the Conference on Retroviruses and Opportunistic Infections (Abstract 136).

“Chronic HBV coinfection is common among people with HIV, but the determinants of HBV-associated HCC are not well characterized,” said presenter H. Nina Kim MD, MSc, of the University of Washington, Seattle. “We sought to identify factors that contribute to HCC development in persons with HIV/HBV coinfection to guide early detection and prevention measures.”

The researchers conducted a longitudinal cohort study within the North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD), a collaboration of single-site and multisite cohorts throughout the United States and Canada; 22 cohorts from NA-ACCORD were included in the analysis.

Potential HIV and HBV risk factors were examined, including viremia and CD4 percentage, as well as HBV DNA levels. Traditional risk factors for liver disease progression, including age, sex, and heavy alcohol use, were also assessed.

Eligible patients were 18 years of age or older who were followed for at least 6 months, had evidence of chronic HBV, and had HIV RNA or CD4+ cell measurement during this period. Persons with prevalent HCC at baseline were excluded.

The primary outcome was first occurrence of HCC, which was adjudicated by medical chart review and/or cancer registry. Multivariable Cox regression was used to determine adjusted hazard ratios of risk factors.
 

Results

Among 9,383 HIV/HBV-coinfected individuals identified, 8,354 (89%) were included in the analysis. The median age of participants was 43 years and 93.1% were male. Heavy alcohol use (35.3%) and chronic hepatitis C virus (HCV) coinfection (21.6%) were common among participants.

Among 8,354 eligible participants, 115 developed HCC over a median 6.9 years of follow-up (incidence rate, 1.8 events per 1,000 person-years; 95% confidence interval [CI], 1.5-2.1).

Independent risk factors for HCC were chronic HCV coinfection (adjusted hazard ratio [aHR], 1.60 [95% confidence interval, 1.07-2.39]), age 40 years and older (aHR, 2.14 [1.36-3.37]), and heavy alcohol use (aHR, 1.51 [1.03-2.21]); however, time-updated CD4+ percentage less than 14% (aHR, 1.03 [0.56-1.90]) and time-updated HIV RNA level over 500 copies/mL (aHR, 0.88 [0.55-1.41]) were not associated with HCC risk.

In a second model, among 3,054 patients who had HBV DNA measured, the risk of HCC was higher with HBV DNA levels greater than 200 IU/mL (aHR, 2.70 [1.23-5.93]), and the risk was particularly elevated at levels greater than 200,000 IU/mL (aHR, 4.34 [1.72-10.94]).

The researchers also found that the risk of HCC was significantly lower in patients with HBV DNA suppression less than 200 IU/mL receiving HBV-active ART for 1 year or more (aHR, 0.42 [0.24-0.73]). In addition, a dose-response relationship was observed between the duration of suppression and this protective effect.

Dr. Nina Kim acknowledged that a key limitation of the study was inconsistent monitoring of HBV DNA level while patients were on treatment. Furthermore, given the demographics of the cohort, these results may not be generalizable outside of North America.

“Our study was the first to show that any level of HBV viremia using 200 as a threshold of detection was associated with HCC risk in a large regionally diverse cohort of adults outside of Asia,” Dr. Kim said. “To gain maximal protective benefit from antiviral therapy for HCC prevention, sustained and ideally uninterrupted suppression of HBV may be necessary over years.”

“HIV/HBV coinfected patients can take much longer than a year to achieve less than 200 copies on HBV DNA due to their baseline levels, but we still don’t know if HBV therapy intensification could hasten this process,” said moderator Robert T. Schooley, MD, of the University of California, San Diego.

Dr. Kim disclosed no conflicts of interest. The study was supported by multiple sources, including the National Institutes of Health, the Centers for Disease Control and Prevention, and the National Cancer Institute.

Thu, 02/18/2021 - 14:31

John G. Bartlett, MD, professor emeritus at Johns Hopkins University School of Medicine, Baltimore, and a prominent leader and instructor in infectious disease medicine, died Jan. 19 at age 83. The cause of death was not immediately disclosed.

Dr. John G. Bartlett

Dr. Bartlett is remembered by colleagues for his wide range of infectious disease expertise, an ability to repeatedly predict emerging issues in the field, and for inspiring students and trainees to choose the same specialty. 

“What I consistently found so extraordinary about John was his excitement for ID – the whole field. He had a wonderful sixth sense about what was going to be the next ‘big thing,’” Paul Edward Sax, MD, clinical director of the Infectious Disease Clinic at Brigham and Women’s Hospital in Boston, told this news organization.

“He thoroughly absorbed the emerging research on the topic and then provided the most wonderful clinical summaries,” Dr. Sax said. “His range of expert content areas was unbelievably broad.” Dr. Bartlett was “a true ID polymath.”

Dr. Bartlett was “a giant in the field of infectious diseases,” David Lee Thomas, MD, MPH, said in an interview. He agreed that Dr. Bartlett was a visionary who could anticipate the most exciting developments in the specialty.

Dr. Bartlett also “led the efforts to combat the foes, from HIV to antimicrobial resistance,” said Dr. Thomas, director of the division of infectious diseases and professor of medicine at Johns Hopkins University.
 

A pioneer in HIV research and care

Dr. Bartlett’s early research focused on anaerobic pulmonary and other infections, Bacteroides fragilis pathogenesis, and colitis caused by Clostridioides difficile.

Shortly after joining Johns Hopkins in 1980, he focused on HIV/AIDS research and caring for people with HIV. Dr. Bartlett led clinical trials of new treatments and developed years of HIV clinical treatment guidelines.

“Back when most hospitals, university medical centers, and ID divisions were running away from the AIDS epidemic, John took it on, both as a scientific priority and a moral imperative,” Dr. Sax writes in a blog post for NEJM Journal Watch. “With the help of Frank Polk and the Hopkins president, he established an outpatient AIDS clinic and an inpatient AIDS ward – both of which were way ahead of their time.”

In the same post, Dr. Sax points out that Dr. Bartlett was an expert in multiple areas – any one of which could be a sole career focus. “How many ID doctors are true experts in all of the following distinct topics? HIV, Clostridium difficile, respiratory tract infections, antimicrobial resistance, and anaerobic pulmonary infections.” Dr. Sax writes.
 

Expertise that defined an era

In a piece reviewing the long history of infectious disease medicine at Johns Hopkins published in Clinical Infectious Diseases in 2014, Paul Auwaerter, MD, and colleagues describe his tenure at the institution from 1980 to 2006 as “The Bartlett Era,” notable for the many advances he spearheaded.

“It is nearly impossible to find someone trained in infectious diseases in the past 30 years who has not been impacted by John Bartlett,” Dr. Auwaerter and colleagues note. “His tireless devotion to scholarship, teaching, and patient care remains an inspiration to his faculty members at Johns Hopkins, his colleagues, and coworkers around the world.”

Dr. Bartlett was not only a faculty member in the division of infectious diseases, he also helped establish it. When he joined Johns Hopkins, the infectious disease department featured just three faculty members with a research budget of less than $285,000. By the time he left 26 years later, the division had 44 faculty members on tenure track and a research budget exceeding $40 million.
 

 

 

Sharing memories via social media

Reactions to Dr. Bartlett’s passing on Twitter were swift.

“We have lost one of the greatest physicians I have ever met or had the privilege to learn from. Saddened to hear of Dr. John G. Bartlett’s passing. He inspired so many, including me, to choose the field of infectious diseases,” David Fisk, MD, infectious disease specialist in Santa Barbara, Calif., wrote on Twitter.

“John Bartlett just died – a true visionary and the classic ‘Renaissance’ person in clinical ID. Such a nice guy, too! His IDSA/IDWeek literature summaries (among other things) were amazing. We’ll miss him!” Dr. Sax tweeted on Jan. 19.

A colleague at Johns Hopkins, transplant infectious disease specialist Shmuel Shoham, MD, shared an anecdote about Dr. Bartlett on Twitter: “Year ago. My office is across from his. I ask him what he is doing. He tells me he is reviewing a file from the Vatican to adjudicate whether a miracle happened. True story.”

Infectious disease specialist Graeme Forrest, MBBS, also shared a story about Dr. Bartlett via Twitter. “He described to me in 2001 how the U.S. model of health care would not cope with a pandemic or serious bioterror attack as it’s not connected to disseminate information. How prescient from 20 years ago.”

Dr. Bartlett shared his expertise at many national and international infectious disease conferences over the years. He also authored 470 articles, 282 book chapters, and 61 editions of 14 books.

Dr. Bartlett was also a regular contributor to this news organization. For example, he shared his expertise in perspective pieces that addressed priorities in antibiotic stewardship, upcoming infectious disease predictions, and critical infectious disease topics in a three-part series.

Dr. Bartlett’s education includes a bachelor’s degree from Dartmouth College in Hanover, N.H., in 1959 and an MD from Upstate Medical Center in Syracuse, N.Y., in 1963. He did his first 2 years of residency at Brigham and Women’s Hospital.

He also served as an Army captain from 1965 to 1967, treating patients in fever wards in Vietnam. He then returned to the United States to finish his internal medicine training at the University of Alabama in 1968.

Dr. Bartlett completed his fellowship in infectious diseases at the University of California, Los Angeles. In 1975, he joined the faculty at Tufts University, Boston.
 

Leaving a legacy

Dr. Bartlett’s influence will likely live on in many ways at Johns Hopkins.

“John is a larger-than-life legend whose impact will endure and after whom we are so proud to have named our clinical service, The Bartlett Specialty Practice,” Dr. Thomas said.

The specialty practice clinic named for him has 23 exam rooms and features multidisciplinary care for people with HIV, hepatitis, bone infections, general infectious diseases, and more. Furthermore, friends, family, and colleagues joined forces to create the “Dr. John G. Bartlett HIV/AIDS Fund.”

They note that it is “only appropriate that we honor him by creating an endowment that will provide support for young trainees and junior faculty in the division, helping them transition to their independent careers.”

In addition to all his professional accomplishments, “He was also a genuinely nice person, approachable and humble,” Dr. Sax said. “We really lost a great one!”

“John is a larger-than-life legend whose impact will endure and after whom we are so proud to have named our clinical service, The Bartlett Specialty Practice,” Dr. Thomas said.

The specialty practice clinic named for him has 23 exam rooms and features multidisciplinary care for people with HIV, hepatitis, bone infections, general infectious diseases, and more. Furthermore, friends, family, and colleagues joined forces to create the “Dr. John G. Bartlett HIV/AIDS Fund.”

They note that it is “only appropriate that we honor him by creating an endowment that will provide support for young trainees and junior faculty in the division, helping them transition to their independent careers.”

In addition to all his professional accomplishments, “He was also a genuinely nice person, approachable and humble,” Dr. Sax said. “We really lost a great one!”

Dr. Bartlett is remembered by colleagues for his wide range of infectious disease expertise, an ability to repeatedly predict emerging issues in the field, and for inspiring students and trainees to choose the same specialty. 

“What I consistently found so extraordinary about John was his excitement for ID – the whole field. He had a wonderful sixth sense about what was going to be the next ‘big thing,’” Paul Edward Sax, MD, clinical director of the Infectious Disease Clinic at Brigham and Women’s Hospital in Boston, told this news organization.

“He thoroughly absorbed the emerging research on the topic and then provided the most wonderful clinical summaries,” Dr. Sax said. “His range of expert content areas was unbelievably broad.” Dr. Bartlett was “a true ID polymath.”

Dr. Bartlett was “a giant in the field of infectious diseases,” David Lee Thomas, MD, MPH, said in an interview. He agreed that Dr. Bartlett was a visionary who could anticipate the most exciting developments in the specialty.

Dr. Bartlett also “led the efforts to combat the foes, from HIV to antimicrobial resistance,” said Dr. Thomas, director of the division of infectious diseases and professor of medicine at Johns Hopkins University.
 

A pioneer in HIV research and care

Dr. Bartlett’s early research focused on anaerobic pulmonary and other infections, Bacteroides fragilis pathogenesis, and colitis caused by Clostridioides difficile.

Shortly after joining Johns Hopkins in 1980, he focused on HIV/AIDS research and caring for people with HIV. Dr. Bartlett led clinical trials of new treatments and developed years of HIV clinical treatment guidelines.

“Back when most hospitals, university medical centers, and ID divisions were running away from the AIDS epidemic, John took it on, both as a scientific priority and a moral imperative,” Dr. Sax writes in a blog post for NEJM Journal Watch. “With the help of Frank Polk and the Hopkins president, he established an outpatient AIDS clinic and an inpatient AIDS ward – both of which were way ahead of their time.”

In the same post, Dr. Sax points out that Dr. Bartlett was an expert in multiple areas – any one of which could be a sole career focus. “How many ID doctors are true experts in all of the following distinct topics? HIV, Clostridium difficile, respiratory tract infections, antimicrobial resistance, and anaerobic pulmonary infections.” Dr. Sax writes.
 

Expertise that defined an era

In a piece reviewing the long history of infectious disease medicine at Johns Hopkins published in Clinical Infectious Diseases in 2014, Paul Auwaerter, MD, and colleagues describe his tenure at the institution from 1980 to 2006 as “The Bartlett Era,” notable for the many advances he spearheaded.

“It is nearly impossible to find someone trained in infectious diseases in the past 30 years who has not been impacted by John Bartlett,” Dr. Auwaerter and colleagues note. “His tireless devotion to scholarship, teaching, and patient care remains an inspiration to his faculty members at Johns Hopkins, his colleagues, and coworkers around the world.”

Dr. Bartlett was not only a faculty member in the division of infectious diseases, he also helped establish it. When he joined Johns Hopkins, the infectious disease department featured just three faculty members with a research budget of less than $285,000. By the time he left 26 years later, the division had 44 faculty members on tenure track and a research budget exceeding $40 million.
 

 

 

Sharing memories via social media

Reactions to Dr. Bartlett’s passing on Twitter were swift.

“We have lost one of the greatest physicians I have ever met or had the privilege to learn from. Saddened to hear of Dr. John G. Bartlett’s passing. He inspired so many, including me, to choose the field of infectious diseases,” David Fisk, MD, infectious disease specialist in Santa Barbara, Calif., wrote on Twitter.

“John Bartlett just died – a true visionary and the classic ‘Renaissance’ person in clinical ID. Such a nice guy, too! His IDSA/IDWeek literature summaries (among other things) were amazing. We’ll miss him!” Dr. Sax tweeted on Jan. 19.

A colleague at Johns Hopkins, transplant infectious disease specialist Shmuel Shoham, MD, shared an anecdote about Dr. Bartlett on Twitter: “Year ago. My office is across from his. I ask him what he is doing. He tells me he is reviewing a file from the Vatican to adjudicate whether a miracle happened. True story.”

Infectious disease specialist Graeme Forrest, MBBS, also shared a story about Dr. Bartlett via Twitter. “He described to me in 2001 how the U.S. model of health care would not cope with a pandemic or serious bioterror attack as it’s not connected to disseminate information. How prescient from 20 years ago.”

Dr. Bartlett shared his expertise at many national and international infectious disease conferences over the years. He also authored 470 articles, 282 book chapters, and 61 editions of 14 books.

Dr. Bartlett was also a regular contributor to this news organization. For example, he shared his expertise in perspective pieces that addressed priorities in antibiotic stewardship, upcoming infectious disease predictions, and critical infectious disease topics in a three-part series.

Dr. Bartlett’s education includes a bachelor’s degree from Dartmouth College in Hanover, N.H., in 1959 and an MD from Upstate Medical Center in Syracuse, N.Y., in 1963. He did his first 2 years of residency at Brigham and Women’s Hospital.

He also served as an Army captain from 1965 to 1967, treating patients in fever wards in Vietnam. He then returned to the United States to finish his internal medicine training at the University of Alabama in 1968.

Dr. Bartlett completed his fellowship in infectious diseases at the University of California, Los Angeles. In 1975, he joined the faculty at Tufts University, Boston.

The changing brain signature of HIV

Article Type
Changed
Fri, 02/12/2021 - 15:30

 

Combination antiretroviral therapy (cART) has shifted HIV infection from a fatal to a chronic condition. New evidence now suggests this has been accompanied by a shift in the profile of HIV-related brain abnormalities beyond the basal ganglia, frequently implicated in the pre-cART era, to limbic structures.

“This shift in subcortical signatures may be contributing to the increasing range of neuropsychiatric and cognitive outcomes,” write Neda Jahanshad, PhD, University of Southern California, Los Angeles, and colleagues.

The study was published online Jan. 15 in JAMA Network Open.
 

Brain signature of HIV

The researchers with the HIV Working Group within the Enhancing Neuro Imaging Genetics Through Meta Analysis (ENIGMA) consortium examined structural brain associations with CD4+ T cell counts and HIV viral load.

These clinical markers are the most consistently available in studies of HIV and generalize across demographically and clinically diverse HIV-infected individuals, they point out. However, the degree to which they capture central nervous system injury is not fully understood.

In this cross-sectional study of 1,203 HIV-infected adults from 13 HIV neuroimaging studies, a lower CD4+ T-cell count was associated with smaller hippocampal and thalamic volume independent of treatment status. However, in a subset of adults not on cART, a lower CD4+ T-cell count was associated with smaller putamen volume.

Across all participants, detectable viral load was associated with smaller hippocampal volume, but in the subset on cART, detectable viral load was also associated with smaller amygdala volume.

The findings indicate that plasma markers universally used to monitor immune function and response to treatment in patients with HIV infection are associated with subcortical brain volume.

“Our findings,” they add, “extend beyond the classically implicated regions of the basal ganglia and may represent a generalizable brain signature of HIV infection in the cART era.”

A limitation of the analysis is that most of the participants were men (n = 880, 73%). “A more extensive international effort assessing the neurologic effects of HIV infection in women is needed,” they conclude.

This analysis, they add, demonstrates the feasibility and utility of a global collaborative initiative to understand the neurologic signatures of HIV infection. They invite other HIV researchers to join the ENIGMA-HIV consortium.

“With a greater collaborative effort, we will be able to assess factors that may modulate neurologic outcomes, including cART treatment regimens, comorbidities, coinfections, substance use, socioeconomic factors, and demographic factors, as well as the functional implications of such structural brain differences, in well-powered analyses,” the researchers say.

“Understanding the neurobiological changes that may contribute to neuropsychiatric and cognitive outcomes in HIV-positive individuals is critical for identifying individuals at risk for neurologic symptoms, driving novel treatments that may protect the CNS, and monitoring treatment response,” they add.

Support for this research was provided by grants from the National Institutes of Health, the SA Medical Research Council, the National Health and Medical Research Council, and the European Research Council. Dr. Jahanshad received partial research support from Biogen for work unrelated to the topic of this article. A complete list of author disclosures is in the original article.

CDC: 20% of people in the U.S. are infected with an STD

Article Type

Thu, 01/28/2021 - 15:02

Among the more than 320 million people in the United States, there was a prevalence estimate of 67.6 million sexually transmitted infections at the time of assessment in 2018, according to the results of an epidemiologic study using multiple data sources, including the National Health and Nutrition Examination Survey (NHANES).

In addition, almost half of the incident STIs occurred in the 15- to 24-year age bracket, according to a report published online in Sexually Transmitted Diseases. Researchers estimated the combined number of prevalent and incident infections of eight STIs in the United States in 2018: chlamydia, gonorrhea, trichomoniasis, syphilis, genital herpes (caused by herpes simplex virus type 2 [HSV-2]), human papillomavirus (HPV), sexually transmitted hepatitis B virus (HBV), and sexually transmitted HIV.

The estimated incidences of these STIs in this update, the first since 2008, were made using more recent data and improved estimation methods to provide updated STI prevalence and incidence estimates for 2018, both overall and by disease. “Having a combined estimate is crucial for policy purposes to illustrate the importance of STIs in the United States,” according to Kristen M. Kreisel, PhD, an epidemiologist at the Centers for Disease Control and Prevention, division of STD prevention, and colleagues.

The number of prevalent and incident infections were obtained by multiplying each STI’s updated per capita estimates by the 2018 full resident population estimates from the American Community Survey.
 

Detailed results

Chlamydia. The prevalence of chlamydia was estimated using 2015-2018 NHANES data, which was then used to create a modeled prevalence in 2018, according to the authors. There were an estimated 2.4 million prevalent urogenital chlamydial infections among persons aged 15-39 years in 2018; 1.1 and 1.3 million infections among men and women, respectively. Individuals aged 15-24 years comprised 56.7% and 75.8% of all infections in men and women respectively.

Gonorrhea. The prevalence of gonorrhea was estimated using ordinary differential equation based modeling. The number of prevalent urogenital gonococcal infections in 2018 among 15- to 39-year-olds was 209,000 overall; 50,000 in men and 155,000 in women. Of these, 113,000 (54.1%) occurred in 15- to 24-year-olds.

Trichomoniasis. The prevalence of trichomoniasis was estimated using 2015-2018 NHANES data, which was then used to create a modeled prevalence in 2018, according to the authors. The number of prevalent Trichomonas infections among 15- to 59-year-olds was 2.6 million, with 470,000 in men and 2.1 million in women. Persons aged 15-24 years comprised 15.6% of all prevalent infections, according to the authors.

Syphilis. The number of estimated prevalent syphilitic infections (all stages) among 14- to 49-year-old persons in 2018 was 156,000, with infections in men comprising 71.8% of all infections. Infections in both men and women aged 14-24 years accounted for about 25% of all infections, with 36,000 total prevalent syphilitic infections among 14- to 24-year-olds in 2018.

Genital herpes. The prevalence of genital herpes (caused by HSV-2) was estimated using 2015-2018 NHANES data, according to the authors. In persons aged 15-49 years in 2018, there were 18.6 million prevalent HSV-2 infections; 6.4 million among men and 12.2 million among women. Infections in 15- to 24-year-olds comprised 7.1% of all prevalent HSV-2 infections.

HPV. The prevalence of HPV was estimated using 2013-2016 NHANES data, which was assumed to reflect stable prevalence in 2018, according to the authors. Among 15- to 59-year-olds, the estimated number of persons, men, and women infected with one or more disease-associated HPV types in 2018 was 42.5, 23.4, and 19.2 million, respectively, with an estimated 9.0 million (21%) 15- to 24-year-olds infected,

HBV. NHANES 2013-2018 data were used to estimate the prevalence of sexually transmitted chronic HBV infections in 2018, according to the authors. The estimated number of infections among persons aged 15 years and older in 2018 was 103,000 (51,000 men and 52,000 women). There small sample size of individuals aged 15-24 years in the NHANES database made it impossible to obtain an accurate estimate for this group, according to the authors.

HIV. Data from the National HIV Surveillance System were used to estimate the prevalence and incidence of sexually transmitted HIV infections for persons aged 13 years and older in 2018. A total of 984,000 individuals aged 13 years and older were estimated to be living with sexually transmitted HIV at the end of 2018, according to the authors. Nearly 80% were men. In the 13- to 24-year-old age bracket, there were an estimated 45,400 living with sexually transmitted HIV.

Billions in costs

Commenting on the study by the CDC researchers, Raul Romaguera, acting director for CDC’s division of STD prevention, stated in a press release: “There are significant human and financial costs associated with these infections, and we know from other studies that cuts in STI prevention efforts result in higher costs down the road. Preventing STIs could save billions in medical costs, but more importantly, prevention would improve the health and lives of millions of people.”

“About 20% of the total U.S. population had an STI at a given point in 2018, while nearly half of all incident infections occurred in people aged 15-24 years. Focusing STI prevention efforts on the 15- to 24-year-old population may be key to lowering the STI burden in the U.S.,” the researchers concluded.

The authors reported that they had no disclosures.

Syphilis. The number of estimated prevalent syphilitic infections (all stages) among 14- to 49-year-old persons in 2018 was 156,000, with infections in men comprising 71.8% of all infections. Infections in both men and women aged 14-24 years accounted for about 25% of all infections, with 36,000 total prevalent syphilitic infections among 14- to 24-year-olds in 2018.

Genital herpes. The prevalence of genital herpes (caused by HSV-2) was estimated using 2015-2018 NHANES data, according to the authors. In persons aged 15-49 years in 2018, there were 18.6 million prevalent HSV-2 infections; 6.4 million among men and 12.2 million among women. Infections in 15- to 24-year-olds comprised 7.1% of all prevalent HSV-2 infections.

HPV. The prevalence of HPV was estimated using 2013-2016 NHANES data, which was assumed to reflect stable prevalence in 2018, according to the authors. Among 15- to 59-year-olds, the estimated number of persons, men, and women infected with one or more disease-associated HPV types in 2018 was 42.5, 23.4, and 19.2 million, respectively, with an estimated 9.0 million (21%) 15- to 24-year-olds infected,

HBV. NHANES 2013-2018 data were used to estimate the prevalence of sexually transmitted chronic HBV infections in 2018, according to the authors. The estimated number of infections among persons aged 15 years and older in 2018 was 103,000 (51,000 men and 52,000 women). There small sample size of individuals aged 15-24 years in the NHANES database made it impossible to obtain an accurate estimate for this group, according to the authors.

HIV. Data from the National HIV Surveillance System were used to estimate the prevalence and incidence of sexually transmitted HIV infections for persons aged 13 years and older in 2018. A total of 984,000 individuals aged 13 years and older were estimated to be living with sexually transmitted HIV at the end of 2018, according to the authors. Nearly 80% were men. In the 13- to 24-year-old age bracket, there were an estimated 45,400 living with sexually transmitted HIV.

Billions in costs

Commenting on the study by the CDC researchers, Raul Romaguera, acting director for CDC’s division of STD prevention, stated in a press release: “There are significant human and financial costs associated with these infections, and we know from other studies that cuts in STI prevention efforts result in higher costs down the road. Preventing STIs could save billions in medical costs, but more importantly, prevention would improve the health and lives of millions of people.”

“About 20% of the total U.S. population had an STI at a given point in 2018, while nearly half of all incident infections occurred in people aged 15-24 years. Focusing STI prevention efforts on the 15- to 24-year-old population may be key to lowering the STI burden in the U.S.,” the researchers concluded.

The authors reported that they had no disclosures.

First monthly injectable HIV treatment approved by FDA

Cabenuva (cabotegravir and rilpivirine, a once-per-month injectable formulation) was approved by the Food and Drug Administration as a complete regimen for treatment of HIV-1 infection in adults. It is intended to replace current antiretroviral regimens in those patients who are virologically suppressed with no history of treatment failure and with no known or suspected resistance to either of the two component drugs.

Cabenuva is the first FDA-approved monthly injectable, complete regimen for HIV-infected adults, according to the agency’s announcement.

In addition, the FDA-approved Vocabria (cabotegravir, tablet formulation), a preparatory treatment intended to be taken in combination with oral rilpivirine (Edurant) for 1 month prior to starting treatment with Cabenuva to ensure the medications are well tolerated before switching to the extended-release injectable formulation. The FDA granted the approval of Cabenuva and Vocabria to ViiV Healthcare.

Cabotegravir is as an integrase strand transfer inhibitor that blocks HIV integrase by attaching to the active integrase site and inhibiting retroviral DNA integration, which is necessary in order for HIV to replicate. In contrast, rilpivirine acts as a diarylpyrimidine nonnucleoside reverse transcriptase inhibitor of HIV-1.

Approval of Cabenuva was based upon two randomized, open-label, controlled clinical trials in 1,182 HIV-infected adults who were virologically suppressed (HIV-1 RNA less than 50 copies/mL) before initiation of treatment with Cabenuva. The two pivotal phase three clinical studies were: Antiretroviral Therapy as Long-Acting Suppression (ATLAS; NCT02951052) and First Long-Acting Injectable Regimen (FLAIR; NCT02938520). Patients in both trials continued to show virologic suppression at the conclusion of each study, and no clinically relevant change from baseline in CD4+ cell counts was observed, according to the FDA announcement.

Adverse reactions with Cabenuva included injection-site reactions, fever, fatigue, headache, musculoskeletal pain, nausea, sleep disorders, dizziness, and rash. The FDA warned that Cabenuva should not be used if there is a known previous hypersensitivity reaction to cabotegravir or rilpivirine, or in patients who are not virally suppressed (HIV-1 RNA greater than 50 copies/mL).

Cabenuva and Vocabria were granted Fast Track and Priority Review designation by the FDA. Prescribing information for Cabenuva is available on the ViiV Healthcare website.
