Upper airway hypoglossal nerve stimulation is safe and effective in adolescents with Down syndrome and severe persistent obstructive sleep apnea (OSA) occurring after adenotonsillectomy and who couldn’t tolerate positive airway pressure, early research suggests.

In a phase I study, 42 adolescents received a surgically implanted device that moves the tongue forward during sleep. Results at 1-year follow-up showed 66% “responded well” to treatment and showed a drop in apnea-hypopnea index (AHI) of at least 50%.

“Parents came back to us and said not only is the sleep better but my child seems to be doing better during the day,” lead investigator Christopher Hartnick, MD, director of the Division of Pediatric Otolaryngology and the Pediatric Airway, Voice, and Swallowing Center at Massachusetts Eye and Ear, Boston, told this news organization.

The findings were published online  in JAMA Otolaryngology – Head and Neck Surgery.
 

Limited options

Upper airway simulation has been shown previously to be effective for adults with OSA, but up until now, the process has not been evaluated in children.

The device used in the current study “stimulates the hypoglossal nerve to protrude the tongue and open the airway on inspiration during sleep,” the investigators note.

“Hypoglossal nerve stimulation may be a particularly suitable therapy for patients with Down syndrome because it can augment neuromuscular airway tone and reduce anatomical obstruction at the base of the tongue, a common site of residual obstruction in children with Down syndrome,” they add.

“This study was born out of the frustration of not having an effective treatment option for children with Down syndrome who struggle with sleep apnea,” Dr. Hartnick said in a news release.

A total of 42 adolescents (67% male; mean age, 15 years) with Down syndrome and persistent severe OSA after adenotonsillectomy were implanted with the hypoglossal nerve stimulator. All were followed for 12 months.

The surgery was safe, with the most common adverse event being temporary tongue discomfort in five patients (12%). This typically resolved in weeks, the researchers note.
 

High response, adherence rates

Results showed response rates and adherence to therapy was high. The mean duration of nightly therapy was 9 hours, with 40 children (95.2%) using the device at least 4 hours every night.

The implant was also effective, with a mean decrease in AHI of 12.9 events per hour (95% confidence interval, –17.0 to –8.7 events per hour).

Nearly two-thirds of the children had at least a 50% reduction in their AHI, while roughly three-fourths had a 12-month follow-up AHI of less than 10 events per hour.

There were also significant improvements in polysomnographic and parent-reported quality of life outcomes 12 months after the implant, including improvement in sleep and daily functioning, behavior, and language.

“Sleep apnea remains one of the most common conditions that I grapple with working with patients with Down syndrome and their families,” co-investigator Brian Skotko, MD, Emma Campbell endowed chair on Down syndrome at Massachusetts General Hospital, Boston, said in the release.

“Until now, so many of our patients had run out of treatment options, and their health and well-being were declining. Now, with the hypoglossal nerve stimulator treatment, we may have an effective and safe way to treat apnea and maximize brain health for people with Down syndrome,” Dr. Skotko added.

Dr. Hartnick and Dr. Skotko have received a $4 million, 5-year grant from the National Institutes of Health to assess whether upper airway stimulation might help cognition in children with Down syndrome.
 

Landmark investigation

Co-authors of an invited commentary said they “applaud” the researchers for their “landmark” investigation, which demonstrated a response to upper airway stimulation in children with Down syndrome and OSA that is on par with what has been achieved in adults with OSA.

“They have established the safety of the procedure; however, future research is necessary to optimize the results of implant,” write Norman Friedman, MD, and Katherine Green, MD, both from the department of otolaryngology – head and neck surgery, University of Colorado School of Medicine, Aurora.

“Further assessment regarding patient selection and the systematic preoperative identification of potential barriers that might affect successful use of therapy will be beneficial to improve longitudinal outcomes and success in this population that is uniquely different from the adult cohorts that have received implants to date,” they add.

The study was funded by Inspire Medical Systems, which provided eight devices for the study but otherwise did not have a role in its design and conduct. The LuMind IDSC Down Syndrome Foundation also provided funding for the study. Dr. Hartnick and the editorialists have disclosed no relevant financial relationships. A complete list of disclosures for the other investigators is available in the original article.

Pfizer is voluntarily recalling five lots of Accupril (quinapril HCI) due to unacceptable levels of a nitrosamine, N-nitroso-quinapril, a potential carcinogen, the company announced.

The Accupril recall comes one month after Pfizer recalled six lots of Accuretic (Quinapril HCI/hydrochlorathiazide) tablets for the same problem.

Accupril is indicated for the treatment of hypertension and management of heart failure when added to conventional therapy, including diuretics and/or digitalis.

To date, Pfizer is not aware of any reports of adverse events related to the Accupril recall, and the company believes the benefit/risk profile remains positive based on currently available data.

“Although long-term ingestion of N-nitroso-quinapril may be associated with a potential increased cancer risk in humans, there is no immediate risk to patients taking this medication,” the company said April 22 in a news release.

Patients currently taking the recalled products are asked to consult with their doctor about alternative treatment options.

The recalled Accupril tablets were sold in 90-count bottles distributed nationwide to wholesalers and distributors in the United States and Puerto Rico from December 2019 to April 2022. 

National drug codes (NDC), lot numbers, and expiration dates are listed in the company announcement posted on the Food and Drug Administration’s website.

Patients who are taking this product should consult with their health care provider or pharmacy to determine if they have the affected product. Those with the affected tablets should contact claims management firm Sedgwick by phone at 888-345-0481 Monday through Friday from 8 AM to 5 PM ET for instructions on how to return the product and obtain reimbursement.

Healthcare providers with questions regarding the recall can contact Pfizer by telephone at 800-438-1985, option 3, Monday through Friday from 8 AM to 9 PM ET.

Adverse reactions or quality problems related to this recall should be reported to the FDA’s MedWatch program.

Antidepressant use is not associated with significant improvement in health-related quality of life (HRQoL) in patients with depression, new research suggests.

Researchers who conducted the study admit this finding was unexpected, and outside experts say no firm conclusions can be drawn from the research.

“Of course we were surprised by the results,” first author Omar Almohammed, PharmD, PhD, College of Pharmacy, King Saud University, Riyadh, Saudi Arabia, told this news organization.

“We were expecting to see some positive impact with the use of antidepressant medications on the HRQoL measures when we compared these patients to patients that did not use antidepressant medications,” Dr. Almohammed said.

The study was published online  in PLOS ONE.
 

Controversial impact on quality of life

Depression is known to harm HRQoL. Despite evidence that antidepressants improve depressed mood, their effect on patients’ overall well-being and HRQoL remains controversial.

The researchers examined the effect of antidepressants on HRQoL in adults with depression using 11 years of data from the U.S. Medical Expenditures Panel Survey (MEPS), a large longitudinal survey that tracks health service use in the United States. HRQoL was measured using the 12-item Short Form Health Survey (SF-12).

On average, about 17.5 million adults were diagnosed with depression each year during the study period (2005-2016). More than half (57.6%) of these patients were treated with antidepressants.

Patients with depression had an average age of 48.3 years. Women made up more than two-thirds of the total sample (68%), and more women than men received antidepressants (61% vs. 52%).

Compared with no antidepressant use, antidepressant use was associated with some improvement on the mental, but not physical, component of the SF-12, the researchers report.

However, difference-in-differences (D-I-D) univariate analysis showed no significant difference between adults using and not using antidepressants in the SF-12 physical (-0.35 vs. -0.34; P = .9,595) or mental component (1.28 vs. 1.13; P = .6,405).

“The multivariate D-I-D analyses ensured the robustness of these results,” the researchers note.

The change in HRQoL observed in patients using antidepressants was not significantly different from that seen among peers not using these drugs, the researchers report.

“We are not saying that antidepressant medications are not helpful at all; HRQoL is only one of many measures intended to assess health outcomes,” Dr. Almohammed told this news organization.

“Based on our research design and data, we can only say that patients who used antidepressant medications did not experience better change in terms of HRQoL compared to patients who did not use antidepressant medications,” he said.

“These patients may have had some improvement on other clinical outcome measures, but that clinical improvement did not have a significant positive impact on HRQoL,” he noted.

“We still recommend that patients continue using their antidepressant medications, but they may want to ask their doctors to provide them with other nonpharmacologic interventions as this may have additional impact on their HRQoL,” Dr. Almohammed said.

Further research is needed to address a “gap in knowledge” about the impact of nondrug interventions – alone or in combination with antidepressant medications – on patients’ HRQoL, Dr. Almohammed added.
 

Experts weigh in

Several experts weighed in on the study in a statement from the British nonprofit Science Media Center.

Gemma Lewis, PhD, with University College London (UCL), noted that “clinical trials with experimental designs have found that antidepressants improve mental health-related quality of life.”

Political elections can be hard on the heart, suggests a study that showed a substantial uptick in hospital admissions for acute cardiovascular conditions immediately after the 2020 American presidential election.

The analysis of nearly 6.4 million adults showed that the rate of hospitalization for acute cardiovascular disease (CVD) was 17% higher in the 5 days after the election than in a 5-day period 2 weeks earlier.

The rate of acute myocardial infarction (AMI) was 42% higher, with no significant difference for heart failure or stroke hospital admissions.

“These findings suggest that awareness of the heightened risk of CVD and strategies to mitigate risk during notable political events are needed,” write Matthew T. Mefford, PhD, of Kaiser Permanente Southern California, Pasadena, and colleagues.

The study was published in the April issue of JAMA Network Open.
 

Stress and the heart

In the American Psychological Association Stress in America 2020 survey conducted roughly 3 months before the 2020 presidential election, 77% of adults cited the future of the country as a substantial source of stress, enhanced by the ongoing COVID-19 pandemic, the authors note. More than two-thirds said the election was a substantial source of stress.

Dr. Mefford and colleagues compared CVD hospitalizations at Kaiser Permanente Southern and Northern California hospitals in the 5-day risk window of Nov. 4-8, 2020, with the control window of Oct. 21-25, 2020.

There were 666 CVD hospitalizations (760.47 per 100,000 person-years [PY]) in the risk window, compared with 569 (647.97 per 100,000 PY) in the control window (rate ratio, 1.17; 95% confidence interval, 1.05-1.31).

There were also significantly more hospitalizations for AMI immediately after the election than before (179 vs. 126 AMI hospitalizations; 204.4 vs. 143.5 per 100,000 PY; RR, 1.42; 95% CI, 1.13-1.79).

There was no significant difference between the risk and control periods for hospitalizations because of stroke or heart failure.

The study also suggests higher rates of acute CVD after the election in older adults, men, and White individuals. Political affiliation was not examined in the study.

“Importantly, results were consistent before and after excluding patients with confirmed COVID-19 infection,” the study team notes.

Yet, the potential influence of COVID-19 stressors on increasing CVD risk cannot be ruled out, they say.

However, COVID-19 stressors occurred over a much longer period and are less likely to explain the transient risks observed in the defined risk and control windows that are in close proximity to the 2020 election, the investigators point out.

There is growing evidence that psychological health contributes to CVD.

Previous studies shown a higher risk for acute CVD around population-wide psychosocial or environmental stressors, but less was known about acute CVD risk in relation to political events.

The researchers note future studies evaluating stress-relieving interventions may be important for understanding the intersection of political events, associated stress, and acute CVD risk.

Partial funding for the study was provided by a grant from the W.K. Kellogg Foundation. The authors have no relevant conflicts of interest.

The analysis of nearly 6.4 million adults showed that the rate of hospitalization for acute cardiovascular disease (CVD) was 17% higher in the 5 days after the election than in a 5-day period 2 weeks earlier.

The rate of acute myocardial infarction (AMI) was 42% higher, with no significant difference for heart failure or stroke hospital admissions.

“These findings suggest that awareness of the heightened risk of CVD and strategies to mitigate risk during notable political events are needed,” write Matthew T. Mefford, PhD, of Kaiser Permanente Southern California, Pasadena, and colleagues.

The study was published in the April issue of JAMA Network Open.
 

Stress and the heart

In the American Psychological Association Stress in America 2020 survey conducted roughly 3 months before the 2020 presidential election, 77% of adults cited the future of the country as a substantial source of stress, enhanced by the ongoing COVID-19 pandemic, the authors note. More than two-thirds said the election was a substantial source of stress.

Dr. Mefford and colleagues compared CVD hospitalizations at Kaiser Permanente Southern and Northern California hospitals in the 5-day risk window of Nov. 4-8, 2020, with the control window of Oct. 21-25, 2020.

There were 666 CVD hospitalizations (760.47 per 100,000 person-years [PY]) in the risk window, compared with 569 (647.97 per 100,000 PY) in the control window (rate ratio, 1.17; 95% confidence interval, 1.05-1.31).

There were also significantly more hospitalizations for AMI immediately after the election than before (179 vs. 126 AMI hospitalizations; 204.4 vs. 143.5 per 100,000 PY; RR, 1.42; 95% CI, 1.13-1.79).

There was no significant difference between the risk and control periods for hospitalizations because of stroke or heart failure.

The study also suggests higher rates of acute CVD after the election in older adults, men, and White individuals. Political affiliation was not examined in the study.

“Importantly, results were consistent before and after excluding patients with confirmed COVID-19 infection,” the study team notes.

Yet, the potential influence of COVID-19 stressors on increasing CVD risk cannot be ruled out, they say.

However, COVID-19 stressors occurred over a much longer period and are less likely to explain the transient risks observed in the defined risk and control windows that are in close proximity to the 2020 election, the investigators point out.

There is growing evidence that psychological health contributes to CVD.

Previous studies shown a higher risk for acute CVD around population-wide psychosocial or environmental stressors, but less was known about acute CVD risk in relation to political events.

The researchers note future studies evaluating stress-relieving interventions may be important for understanding the intersection of political events, associated stress, and acute CVD risk.

Partial funding for the study was provided by a grant from the W.K. Kellogg Foundation. The authors have no relevant conflicts of interest.

Most National Cancer Institute–designated cancer centers fail to publicly disclose negotiated prices for cancer therapies, despite federal requirements to do so.

Among those that do provide this information, new research shows that hospitals substantially mark up prices for top-selling cancer therapies relative to acquisition costs. Median drug price markups across NCI centers and payers ranged from nearly 120% to more than 600%.

As a result, “the total price for an entire treatment course could vary on the order of hundreds of thousands of dollars,” Roy Xiao, MD, department of otolaryngology–head and neck surgery, Massachusetts Eye and Ear Infirmary, Boston, said in an interview.

The study was published online in JAMA Internal Medicine.

Manufacturers often price novel anticancer therapies at more than $100,000 per year, but less is known about how much hospitals mark up these prices for patients with private health insurance and how much negotiated prices vary across centers and payers.

Dr. Xiao and colleagues analyzed private payer-specific negotiated prices for the top 25 parenteral cancer therapies by Medicare Part B spending in 2019 using publicly available hospital price transparency files for 61 NCI-designated cancer centers.

Fewer than half of the centers (44.3%) disclosed payer-specific negotiated prices for at least one top-selling cancer drug. Disclosure rates for different drugs ranged from 21.3% (13 centers) for rituximab with hyaluronidase to 42.6% (26 centers) for rituximab, bevacizumab, or leuprolide.

The researchers also found a wide variation in negotiated prices for cancer therapies across hospitals. Across-center price ratios – defined as the ratio between the 90th and 10th percentile median price per unit – ranged from 2.2 ($16 vs. $36 for pembrolizumab 1 mg) and 15.8 ($247 vs. $3,914 for leuprolide 7.5 mg).

Payer-specific prices also varied considerably between payers at the same center. Among all centers, the median within-center price ratios for cancer therapies ranged from 1.8 (brentuximab) to 2.5 (bevacizumab).

As for the extent of cancer therapy markups, median price markups across centers and payers ranged from 118% (sipuleucel-T) to 634% (leuprolide) more than the estimated cost paid by hospitals.

Conservative estimates of acquisition costs and payer-specific prices yielded markups ranging from 42.1% (sipuleucel-T) to 234.1% (leuprolide).

The authors also provided examples of how these variations might affect the total cost of treatment. For instance, the median total price variation across centers to treat metastatic non–small cell lung cancer with pembrolizumab was $168,405. At one institution, the within-center median price variation for daratumumab as third-line therapy for multiple myeloma was $174,225.

To reduce the financial burden of cancer treatment for patients, the authors suggested implementing public policies “to discourage or prevent excessive hospital price markups on parenteral chemotherapeutics.”

To promote hospital compliance with transparency regulations, in January 2022, the Centers for Medicare & Medicare Services increased penalties for nondisclosure from a fixed maximum of $300 per day to up to $5,500 per day, based on hospital bed size, which would total over $2 million per year, Dr. Xiao said in an interview.

“We would expect that this significant financial penalty would encourage more consistent reporting,” he said.

The study had no specific funding. Dr. Xiao has disclosed no relevant disclosures.

Psychiatric disorders are tied to an increased risk of COVID-19 breakthrough infection, particularly among older adults, new research shows.

“Psychiatric disorders remained significantly associated with incident breakthrough infections above and beyond sociodemographic and medical factors, suggesting that mental health is important to consider in conjunction with other risk factors,” wrote the investigators, led by Aoife O’Donovan, PhD, University of California, San Francisco.

Individuals with psychiatric disorders “should be prioritized for booster vaccinations and other critical preventive efforts, including increased SARS-CoV-2 screening, public health campaigns, or COVID-19 discussions during clinical care,” they added.

The study was published online in JAMA Network Open.
 

Elderly most vulnerable

The researchers reviewed the records of 263,697 veterans who were fully vaccinated against COVID-19.

Just over a half (51.4%) had one or more psychiatric diagnoses within the last 5 years and 14.8% developed breakthrough COVID-19 infections, confirmed by a positive SARS-CoV-2 test.

Psychiatric diagnoses among the veterans included depression, posttraumatic stress, anxiety, adjustment disorder, substance use disorder, bipolar disorder, psychosis, ADHD, dissociation, and eating disorders.

In the overall sample, a history of any psychiatric disorder was associated with a 7% higher incidence of breakthrough COVID-19 infection in models adjusted for potential confounders (adjusted relative risk, 1.07; 95% confidence interval, 1.05-1.09) and a 3% higher incidence in models additionally adjusted for underlying medical comorbidities and smoking (aRR, 1.03; 95% CI, 1.01-1.05).

Most psychiatric disorders were associated with a higher incidence of breakthrough infection, with the highest relative risk observed for substance use disorders (aRR, 1.16; 95% CI, 1.12 -1.21) and adjustment disorder (aRR, 1.13; 95% CI, 1.10-1.16) in fully adjusted models.

Older vaccinated veterans with psychiatric illnesses appear to be most vulnerable to COVID-19 reinfection.

In veterans aged 65 and older, all psychiatric disorders were associated with an increased incidence of breakthrough infection, with increases in the incidence rate ranging from 3% to 24% in fully adjusted models.

In the younger veterans, in contrast, only anxiety, adjustment, and substance use disorders were associated with an increased incidence of breakthrough infection in fully adjusted models.

Psychotic disorders were associated with a 10% lower incidence of breakthrough infection among younger veterans, perhaps because of greater social isolation, the researchers said.
 

Risky behavior or impaired immunity?

“Although some of the larger observed effect sizes are compelling at an individual level, even the relatively modest effect sizes may have a large effect at the population level when considering the high prevalence of psychiatric disorders and the global reach and scale of the pandemic,” Dr. O’Donovan and colleagues wrote.

They noted that psychiatric disorders, including depression, schizophrenia, and bipolar disorders, have been associated with impaired cellular immunity and blunted response to vaccines. Therefore, it’s possible that those with psychiatric disorders have poorer responses to COVID-19 vaccination.

It’s also possible that immunity following vaccination wanes more quickly or more strongly in people with psychiatric disorders and they could have less protection against new variants, they added.

Patients with psychiatric disorders could be more apt to engage in risky behaviors for contracting COVID-19, which could also increase the risk for breakthrough infection, they said.

The study was supported by a UCSF Department of Psychiatry Rapid Award and UCSF Faculty Resource Fund Award. Dr. O’Donovan reported no relevant disclosures.

Sips of pickle juice may be all it takes to lessen the severity of muscle cramps in adults with cirrhosis, according to results of the PICCLES randomized controlled trial.

In the trial, patients with cirrhotic cramps who sipped pickle brine at the onset of a muscle cramp saw a significant decrease in cramp severity relative to peers who sipped tap water when the cramp hit.

“The acid (vinegar) in the brine triggers a nerve reflex to stop the cramp when it hits the throat. This is why only a sip is needed,” lead investigator Elliot Tapper, MD, division of gastroenterology and hepatology, University of Michigan, Ann Arbor, told this news organization. The study was published online April 13 in American Journal of Gastroenterology.
 

Common and bothersome

Cramps are common in adults with cirrhosis, irrespective of disease severity. They can sometimes last for hours, and treatment options are limited.

In a prior study, 1 tablespoon of pickle juice rapidly stopped experimentally induced cramps.

“This is something that athletes use, and kidney doctors often recommend to their patients, so it is nothing unique to cirrhosis,” Dr. Tapper said.

The PICCLES trial involved 74 adults (mean age, 56.6 years) with at least 4 muscle cramps in the prior month. In the cohort, 54% were men, and 41% had ascites.

The median cramp frequency was 11-12 per month, with an average cramp severity of more than 4 out of 10 on the Visual Analog Scale (VAS) for cramps. 

Some patients were receiving medications for their cramps at baseline, such as magnesium, potassium, baclofen, vitamin E, taurine, and gabapentin/pregabalin.

Thirty-eight patients were randomly allocated to sip pickle juice and 36 to sip tap water at the onset of a muscle cramp.

The proportion of cramps treated was similar in the pickle juice and tap water groups (77% and 72%). More patients in the pickle juice group said their cramps were aborted by the intervention (69% vs. 40%).

The primary outcome was the change in cramp severity at 28-days VAS for cramps. Cramps were assessed 10 times over 28 days using interactive text messages.

Pickle juice was associated with a larger average reduction in cramp severity than tap water (–2.25 points vs. –0.36 on the VAS-cramps), a difference that was statistically significant (P = .03).

There were no significant changes in the proportion of days with cramp severity of more than 5 on the VAS, or on sleep quality or health-related quality of life. 

Because pickle juice contains sodium, the researchers also assessed weight change as a safety outcome. They found no significant differences in weight change between the two groups overall or in the subset with ascites.

Pickle juice is a “safe option that can stop painful cramps,” Dr. Tapper said in an interview, but was “disheartened” that it did not improve quality of life.

Dr. Tapper encourages patients with cramps to ask their doctor about pickle juice and doctors to ask their patients about muscle cramps.

“Awareness of a patient’s cramps is often lacking. Asking about cramps is not routine but could be the most important advance relating to this study,” he said.

While sips of pickle juice are “unlikely to cause harm,” Dr. Tapper said, he is “a little nervous about advising patients to address their complex needs alone. [Doctors] are there to think through the root causes and help make adjustments that could prevent the cramps in the first place,” he said.
 

Outside experts weigh in

This news organization reached out to several outside experts for their perspective on the study.

Nancy Reau, MD, professor of internal medicine, associate director of solid organ transplantation, and section chief of hepatology. Rush University Medical Center, Chicago, noted that interventions to manage and prevent muscle cramps are “important, as cramping is common in cirrhosis and strongly affects quality of life.”

Dr. Reau cautioned that while pickle juice “sounds benign, it does have a lot of salt. Despite the salt content, this study didn’t show any difference between patients with and without ascites.

“However, cramping is more common in our patients with sarcopenia and those on diuretics for fluid management and it would be easy to see how this might impact fluid management,” Dr. Reau noted.

“Given that it is the acid (not the salt) in the pickle juice, there might be low salt alternatives,” Dr. Reau said.

Echoing Dr. Reau, Ankur Shah, MD, division of kidney disease and hypertension, Brown University, Providence, R.I., noted that “overuse of pickle juice could place patients at risk of developing high blood pressure and fluid overload, and pickle juice should be included in the sodium restriction guidance given to patients with high blood pressure and heart failure.”

In this study, however, the individual dose consumed was low, Dr. Shah noted.

He said the study “elegantly provides evidence to support the practice of sipping pickle juice for cramping.”

The authors should be “applauded for studying a simple solution with the most rigorous of methodologies, a randomized controlled trial,” Dr. Shah added.  

“This simple treatment may be helpful to patients far beyond those with just cirrhosis, and expect future studies to explore this treatment in other populations,” Dr. Shah said in an interview.

Paul Martin, MD, chief of the division of digestive health and liver diseases and Mandel Chair in Gastroenterology, University of Miami, noted that, while muscle cramps can have a major impact on quality of life, “in terms of some of the other complications of cirrhosis that health care providers are dealing with, they may seem relatively innocuous, but obviously patients have a slightly different interpretation because of the effect cramps can have on sleep and so on.

“There have been a variety of home remedies to treat muscle cramps, but this study is intriguing as it suggests that pickle juice, which is freely available, helps mitigate the severity of the cramps. However, it’s unclear whether it prevents cramps,” Dr. Martin said in an interview.

Given that the study is getting traction on Twitter, Dr. Martin encouraged health care providers to be aware of the study and prepared to answer questions from patients.

Sips of pickle juice may be all it takes to lessen the severity of muscle cramps in adults with cirrhosis, according to results of the PICCLES randomized controlled trial.

In the trial, patients with cirrhotic cramps who sipped pickle brine at the onset of a muscle cramp saw a significant decrease in cramp severity relative to peers who sipped tap water when the cramp hit.

“The acid (vinegar) in the brine triggers a nerve reflex to stop the cramp when it hits the throat. This is why only a sip is needed,” lead investigator Elliot Tapper, MD, division of gastroenterology and hepatology, University of Michigan, Ann Arbor, told this news organization. The study was published online April 13 in American Journal of Gastroenterology.
 

Common and bothersome

Cramps are common in adults with cirrhosis, irrespective of disease severity. They can sometimes last for hours, and treatment options are limited.

In a prior study, 1 tablespoon of pickle juice rapidly stopped experimentally induced cramps.

“This is something that athletes use, and kidney doctors often recommend to their patients, so it is nothing unique to cirrhosis,” Dr. Tapper said.

The PICCLES trial involved 74 adults (mean age, 56.6 years) with at least 4 muscle cramps in the prior month. In the cohort, 54% were men, and 41% had ascites.

The median cramp frequency was 11-12 per month, with an average cramp severity of more than 4 out of 10 on the Visual Analog Scale (VAS) for cramps. 

Some patients were receiving medications for their cramps at baseline, such as magnesium, potassium, baclofen, vitamin E, taurine, and gabapentin/pregabalin.

Thirty-eight patients were randomly allocated to sip pickle juice and 36 to sip tap water at the onset of a muscle cramp.

The proportion of cramps treated was similar in the pickle juice and tap water groups (77% and 72%). More patients in the pickle juice group said their cramps were aborted by the intervention (69% vs. 40%).

The primary outcome was the change in cramp severity at 28-days VAS for cramps. Cramps were assessed 10 times over 28 days using interactive text messages.

Pickle juice was associated with a larger average reduction in cramp severity than tap water (–2.25 points vs. –0.36 on the VAS-cramps), a difference that was statistically significant (P = .03).

There were no significant changes in the proportion of days with cramp severity of more than 5 on the VAS, or on sleep quality or health-related quality of life. 

Because pickle juice contains sodium, the researchers also assessed weight change as a safety outcome. They found no significant differences in weight change between the two groups overall or in the subset with ascites.

Pickle juice is a “safe option that can stop painful cramps,” Dr. Tapper said in an interview, but was “disheartened” that it did not improve quality of life.

Dr. Tapper encourages patients with cramps to ask their doctor about pickle juice and doctors to ask their patients about muscle cramps.

“Awareness of a patient’s cramps is often lacking. Asking about cramps is not routine but could be the most important advance relating to this study,” he said.

While sips of pickle juice are “unlikely to cause harm,” Dr. Tapper said, he is “a little nervous about advising patients to address their complex needs alone. [Doctors] are there to think through the root causes and help make adjustments that could prevent the cramps in the first place,” he said.
 

Outside experts weigh in

This news organization reached out to several outside experts for their perspective on the study.

Nancy Reau, MD, professor of internal medicine, associate director of solid organ transplantation, and section chief of hepatology. Rush University Medical Center, Chicago, noted that interventions to manage and prevent muscle cramps are “important, as cramping is common in cirrhosis and strongly affects quality of life.”

Dr. Reau cautioned that while pickle juice “sounds benign, it does have a lot of salt. Despite the salt content, this study didn’t show any difference between patients with and without ascites.

“However, cramping is more common in our patients with sarcopenia and those on diuretics for fluid management and it would be easy to see how this might impact fluid management,” Dr. Reau noted.

“Given that it is the acid (not the salt) in the pickle juice, there might be low salt alternatives,” Dr. Reau said.

Echoing Dr. Reau, Ankur Shah, MD, division of kidney disease and hypertension, Brown University, Providence, R.I., noted that “overuse of pickle juice could place patients at risk of developing high blood pressure and fluid overload, and pickle juice should be included in the sodium restriction guidance given to patients with high blood pressure and heart failure.”

In this study, however, the individual dose consumed was low, Dr. Shah noted.

He said the study “elegantly provides evidence to support the practice of sipping pickle juice for cramping.”

The authors should be “applauded for studying a simple solution with the most rigorous of methodologies, a randomized controlled trial,” Dr. Shah added.  

“This simple treatment may be helpful to patients far beyond those with just cirrhosis, and expect future studies to explore this treatment in other populations,” Dr. Shah said in an interview.

Paul Martin, MD, chief of the division of digestive health and liver diseases and Mandel Chair in Gastroenterology, University of Miami, noted that, while muscle cramps can have a major impact on quality of life, “in terms of some of the other complications of cirrhosis that health care providers are dealing with, they may seem relatively innocuous, but obviously patients have a slightly different interpretation because of the effect cramps can have on sleep and so on.

“There have been a variety of home remedies to treat muscle cramps, but this study is intriguing as it suggests that pickle juice, which is freely available, helps mitigate the severity of the cramps. However, it’s unclear whether it prevents cramps,” Dr. Martin said in an interview.

Given that the study is getting traction on Twitter, Dr. Martin encouraged health care providers to be aware of the study and prepared to answer questions from patients.

The study had no specific funding. Dr. Tapper has served as a consultant to Novartis, Axcella, and Allergan, has served on advisory boards for Mallinckrodt, Bausch Health, Kaleido, and Novo Nordisk, and has received unrestricted research grants from Gilead and Valeant.

For injection drug users with hepatitis C virus (HCV) infection, providing treatment opportunities within a local needle exchange program can provide care to more patients and eventually cure more patients, a new study suggests.

The study’s findings help “counteract the implicit belief within the medical community that people who inject drugs can’t or don’t want to engage in health care,” lead author Benjamin Eckhardt, MD, with NYU Grossman School of Medicine, told this news organization.

“By simply focusing on patient accompaniment, limiting stigma, and removing the punitive response for missed appointments, we can effectively engage people who inject drugs in health care and more specifically cure their infection, making significant inroads to HCV elimination,” Dr. Eckhardt said.

The study was published online  in JAMA Internal Medicine.
 

Nonjudgmental, patient-centered approach

Researchers included 165 injection drug users with HCV (mean age, 42 years; 78% men); 82 were randomly allocated to the accessible care intervention and 83 to a usual care control group.

The accessible care model provides HCV treatment within a community-based needle exchange program in a comfortable, nonjudgmental atmosphere, “without fear of shame or stigma that people who inject drugs often experience in mainstream institutions,” the investigators explain.

Control participants were connected to a patient navigator who facilitated referrals to community direct antigen antiviral therapy programs that were not at a syringe service program.

In an intent-to-treat analysis, those enrolled in the accessible care group achieved sustained viral eradication at 12 months at significantly higher rates than those in the control group (67% vs. 23%; P < .001).

Once patients initiated treatment, cure rates were the same in both groups (86%), indicating that the major benefit of the accessible care program was in facilitating treatment, rather than increasing adherence to or response to treatment, the researchers noted.

This is reflected in the fact that the percentage of participants who advanced along the care cascade was significantly higher at each step for the accessible care group than the control group, from referral to an HCV clinician (93% vs. 45%), attendance of the initial HCV clinical visit (87% vs. 37%), completion of baseline laboratory testing (87% vs. 31%), and treatment initiation (78% vs. 27%).
 

Getting to the population in need

“The most surprising aspect of the study was how successful we were at recruiting, engaging, and treating people who inject drugs who lived outside the immediate community where the syringe exchange program was located and had no prior connection to the program,” Dr. Eckhardt said.

“We had numerous individuals travel 45-plus minutes on the subway from the South Bronx, passing four major medical centers with robust hepatitis C treatment programs, to seek care for hepatitis C in a small, dark office – but also an office they’d heard can be trusted – without fear of stigma or preconditions,” Dr. Eckhardt said.

Commenting on the study’s findings, Nancy Reau, MD, section chief of hepatology at Rush Medical College, Chicago, said, “This is another successful example of making therapy accessible to the population who is in need versus trying to move them into a tertiary care model.”

Dr. Reau noted that similar care models exist in the United States but are not always accessible to the population in need.

“The safety and efficacy of current therapy and the simplified care cascade make HCV an appropriate disease for this delivery,” she said, adding that this study “highlights not just the importance of these programs but also the necessity of engaging the medical community, changing policy, and using patient navigators and monetary support/prioritization to provide appropriate HCV management to those who are at high risk for the disease and for transmission.”
 

Accessible care beyond HCV

The coauthors of an accompanying editor’s note point out that the treatment for HCV has improved substantially, but it can be a real challenge to provide treatment to injection drug users because the U.S. health care system is not oriented toward the needs of this population.

“It is not surprising that the accessible care arm achieved a higher rate of viral eradication, as it created a patient-focused experience,” write Asha Choudhury, MD, MPH, with the University of California, San Francisco, and Mitchell Katz, MD, with NYC Health and Hospitals. “Creating inviting and engaging environments is particularly important when caring for patients from stigmatized groups. Having more sites that are accessible and inclusive like this for treating patients will likely increase treatment of hepatitis C.”

In their view, the study raises “two dueling questions: Is this model replicable across the U.S.? And, conversely, why isn’t all medical care offered in friendly, nonjudgmental settings with the intention of meeting patient goals?”

They conclude that the study’s lessons extend beyond this particular population and have implications for the field at large.

“The model is replicable to the extent that health care systems are prepared to provide nonjudgmental supportive care for persons who inject drugs,” they write. “However, all patients would benefit from a health care system that provided more patient-centered environments.”

The study was funded by the National Institute on Drug Abuse. Dr. Eckhardt reports receiving grants from the National Institutes of Health and Gilead during the conduct of the study. Dr. Choudhury, Dr. Katz, and Dr. Reau report no relevant financial relationships.

Statins may protect against age-related parkinsonism, new research suggests. An observational study showed older adults taking statins had a lower risk for parkinsonism than their counterparts not taking statins – an effect that may be partially mediated by less severe intracranial atherosclerosis in statin users.

“These findings further support the idea that cerebrovascular disease pathologies accumulating in older brains may be an unrecognized contributor to the common occurrence of parkinsonism in old age,” the investigators wrote. “More importantly, these findings suggest that statins may have a potential therapeutic role in decreasing the magnitude of parkinsonism in older adults,” they added.

The study was published online in Neurology.
 

No clinical recommendations ... yet

The findings are based on 2,841 older adults enrolled in one of three ongoing clinical pathological studies at Rush Alzheimer’s Disease Center, Chicago.

Participants’ average age at baseline was 76 years, and 75% were women. None had parkinsonism at the start of the study. One-third of participants (n = 936) were taking statins. During an average follow-up of 6 years, 1,432 (50%) participants developed parkinsonism.

After controlling for demographics, vascular risk factors, and diseases, use of a statin at baseline was associated with a 16% lower risk for parkinsonism (hazard ratio, 0.84; 95% confidence interval, 0.74-0.96; P = .008). Compared with low-intensity statin therapy, moderate- or high-intensity statin therapy was associated with a 7% lower risk for parkinsonism (HR, 0.93; 95% CI, 0.87-1.00; P = .043).

The researchers also examined the brains of 1,044 people who died during the study at a mean age of 89 years. They found statin use prior to death was associated with a 37% lower odds of cerebral atherosclerosis, compared with no statin use prior to death (odds ratio, 0.63; 95% CI, 0.50-0.79; P < .001).

In a mediation analysis, both a direct (OR, 0.73; 95% CI, 0.54-0.93; P = .008) and an indirect (OR, 0.92; 95% CI, 0.88-0.97; P = .002) pathway via less severe cerebrovascular disease linked statins to parkinsonism, indicating that cerebral atherosclerosis mediated 17% of the association between statins and parkinsonism.

In line with other studies, there was no association between statins and other neurodegenerative pathologies, including Parkinson’s disease pathology. However, even older adults with a clinical diagnosis of Parkinson’s disease often show mixed brain pathologies, including cerebrovascular disease pathologies.

“Therefore, we think that statins may be beneficial against parkinsonism in patients with Parkinson’s disease, dependent on how much cerebrovascular disease pathologies they have, including atherosclerosis,” said study investigator Shahram Oveisgharan, MD, with Rush Alzheimer’s Disease Center, Rush University Medical Center, Chicago.

However, since the results stem from an observational study, “we do not yet recommend using statins in large scale for older adults at risk for parkinsonism,” Dr. Oveisgharan said.
 

A mixed picture

Reached for comment, Shaheen Lakhan, MD, neurologist in Newton, Massachusetts, noted that since statins were first discovered in the fermented broth of a common soil fungus in the late 1970s, they have proven to reduce cholesterol, heart disease, and stroke.

“The jury is out, however, on [their] effects on diseases such as dementia, autoimmune/inflammatory conditions, bacterial/viral infections, cancer, and parkinsonism,” he said.

“Also, the question often remains whether any benefit gained from statins is from cholesterol-lowering or through another mechanism. When there is such a mixed picture, it generally means that the drug has an effect, but not for everyone,” Dr. Lakhan said. “Much work must now be done to stratify for which patients are statins effective, ineffective, or even harmful in these conditions,” he added.

The study was supported by the National Institutes of Health. Dr. Oveisgharan and Dr. Lakhan have disclosed no relevant financial relationships.

They found statin use prior to death was associated with a 37% lower odds of cerebral atherosclerosis, compared with no statin use prior to death (odds ratio, 0.63; 95% CI, 0.50-0.79; P < .001).

In a mediation analysis, both a direct (OR, 0.73; 95% CI, 0.54-0.93; P = .008) and an indirect (OR, 0.92; 95% CI, 0.88-0.97; P = .002) pathway via less severe cerebrovascular disease linked statins to parkinsonism, indicating that cerebral atherosclerosis mediated 17% of the association between statins and parkinsonism.

In line with other studies, there was no association between statins and other neurodegenerative pathologies, including Parkinson’s disease pathology. However, even older adults with a clinical diagnosis of Parkinson’s disease often show mixed brain pathologies, including cerebrovascular disease pathologies.

“Therefore, we think that statins may be beneficial against parkinsonism in patients with Parkinson’s disease, dependent on how much cerebrovascular disease pathologies they have, including atherosclerosis,” said study investigator Shahram Oveisgharan, MD, with Rush Alzheimer’s Disease Center, Rush University Medical Center, Chicago.

However, since the results stem from an observational study, “we do not yet recommend using statins in large scale for older adults at risk for parkinsonism,” Dr. Oveisgharan said.
 

A mixed picture

Reached for comment, Shaheen Lakhan, MD, neurologist in Newton, Massachusetts, noted that since statins were first discovered in the fermented broth of a common soil fungus in the late 1970s, they have proven to reduce cholesterol, heart disease, and stroke.

“The jury is out, however, on [their] effects on diseases such as dementia, autoimmune/inflammatory conditions, bacterial/viral infections, cancer, and parkinsonism,” he said.

“Also, the question often remains whether any benefit gained from statins is from cholesterol-lowering or through another mechanism. When there is such a mixed picture, it generally means that the drug has an effect, but not for everyone,” Dr. Lakhan said. “Much work must now be done to stratify for which patients are statins effective, ineffective, or even harmful in these conditions,” he added.

The study was supported by the National Institutes of Health. Dr. Oveisgharan and Dr. Lakhan have disclosed no relevant financial relationships.

Statins may protect against age-related parkinsonism, new research suggests. An observational study showed older adults taking statins had a lower risk for parkinsonism than their counterparts not taking statins – an effect that may be partially mediated by less severe intracranial atherosclerosis in statin users.

“These findings further support the idea that cerebrovascular disease pathologies accumulating in older brains may be an unrecognized contributor to the common occurrence of parkinsonism in old age,” the investigators wrote. “More importantly, these findings suggest that statins may have a potential therapeutic role in decreasing the magnitude of parkinsonism in older adults,” they added.

The study was published online in Neurology.
 

No clinical recommendations ... yet

The findings are based on 2,841 older adults enrolled in one of three ongoing clinical pathological studies at Rush Alzheimer’s Disease Center, Chicago.

Participants’ average age at baseline was 76 years, and 75% were women. None had parkinsonism at the start of the study. One-third of participants (n = 936) were taking statins. During an average follow-up of 6 years, 1,432 (50%) participants developed parkinsonism.

After controlling for demographics, vascular risk factors, and diseases, use of a statin at baseline was associated with a 16% lower risk for parkinsonism (hazard ratio, 0.84; 95% confidence interval, 0.74-0.96; P = .008). Compared with low-intensity statin therapy, moderate- or high-intensity statin therapy was associated with a 7% lower risk for parkinsonism (HR, 0.93; 95% CI, 0.87-1.00; P = .043).

A new study suggests that overgrowth of the amygdala in infants during the first 6-12 months of life is tied to a later diagnosis of autism spectrum disorder (ASD).

“The faster the amygdala grew in infancy, the more social difficulties the child showed when diagnosed with autism a year later,” first author Mark Shen, PhD, assistant professor of psychiatry and neuroscience, University of North Carolina, Chapel Hill, told this news organization.

The study was published online  in the American Journal of Psychiatry.
 

Unique to autism

The amygdala plays a key role in processing memory, emotional responses, and decisionmaking. 

It’s long been known that the amygdala is abnormally large in school-aged children with ASD, but until now, it was not known precisely when aberrant amygdala growth happens, what the clinical consequences may be, and whether amygdala overgrowth is unique to autism.

To investigate, Dr. Shen and colleagues evaluated 1,099 longitudinal MRI scans obtained during natural sleep at 6, 12, and 24 months of age in 408 infants in the Infant Brain Imaging Study (IBIS) Network.

The cohort included 58 infants at high likelihood of developing ASD who were later diagnosed with the disorder, 212 infants at high likelihood of ASD who did not develop ASD, 109 typically-developing control infants, and 29 infants with fragile X syndrome.

At 6 months, infants who developed ASD had typically sized amygdala volumes but showed significantly faster amygdala growth between 6 and 24 months, such that by 12 months the ASD group had significantly larger amygdala volume (Cohen’s d = 0.56), compared with all other groups.

Amygdala growth rate between 6 and 12 months was significantly associated with greater social deficits at 24 months when the children were diagnosed with ASD.

“We found that the amygdala grows too rapidly between 6 and 12 months of age, during a presymptomatic period in autism, prior to when the diagnostic symptoms of autism (social difficulties and repetitive behaviors) are evident and lead to the later diagnosis of autism,” Dr. Shen said in an interview.

This brain growth pattern appears to be unique to autism, as babies with the genetic disorder fragile X syndrome – another neurodevelopmental condition – showed a markedly different brain growth pattern: no differences in amygdala growth but enlargement of a different brain structure, the caudate, which was linked to increased repetitive behaviors, the investigators found.
 

Earlier intervention

Prior research has shown that children who are later diagnosed with ASD often display problems in infancy with how they attend to visual stimuli in their surroundings.

These early problems with processing visual and sensory information may put increased stress on the amygdala, potentially leading to amygdala hyperactivity, deficits in pruning dendritic connections, and overgrowth, Dr. Shen and colleagues hypothesize.

Amygdala overgrowth has also been linked to chronic stress in studies of other psychiatric conditions, such as depression and anxiety, and may provide a clue to understanding this observation in infants who later develop autism.

“This research suggests that an optimal time to begin supports for children who are at the highest likelihood of developing autism may be during the first year of life: to improve early precursors to social development, such as sensory processing, in babies even before social difficulties arise,” Dr. Shen said.

Cyrus A. Raji, MD, PhD, assistant professor of radiology and neurology, Washington University, St. Louis, said, “What makes this study important is the finding of abnormally increased amygdala growth rate in autism using a longitudinal design that focuses on earlier development.”

“While we are typically used to understanding brain structure as abnormally decreasing over time in certain disorders like Alzheimer’s disease, this study challenges us to understand that too much brain volume growth can also be abnormal in specific conditions,” Dr. Raji added.

This research was supported by grants from the Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institute of Environmental Health Sciences, and National Institute of Mental Health, along with Autism Speaks and the Simons Foundation. Dr. Shen and Dr. Raji have disclosed no relevant financial relationships.
