Clinician Reviews

TOPLINE:

The prevalence of elevated LDL cholesterol (LDL-C) has declined over the past 2 decades, but 1 in 17 Americans still have a level of 160-189 mg/dL, and 1 in 48 have a level of at least 190 mg/dL, new research shows. Among people with the higher LDL-C level, one in four are both unaware and untreated, the authors report.

METHODOLOGY:

• Using data on 23,667 adult participants in the National Health and Nutrition Examination Survey conducted from 1999 to 2020, researchers identified 1,851 (7.8%) with an LDL-C level of 160-189 mg/dL and 669 (2.8%) with an LDL-C level of at least 190 mg/dL.
• Individuals were classified as “unaware” if they had never had their LDL-C measured or had never been informed of having elevated LDL-C and as “untreated” if their medications didn’t include a statin, ezetimibe, a bile acid sequestrant, or a proprotein convertase subtilisin/kexin type 9 inhibitor.
• The authors compared the prevalence of “unaware” and “untreated” by age, sex, race and ethnicity, educational attainment, poverty index, and insurance status.

TAKEAWAY:

• During the study period, the age-adjusted prevalence of an LDL-C level of 160-189 mg/dL declined from 12.4% (95% confidence interval, 10.0%-15.3%), representing 21.5 million U.S. adults, to 6.1% (95% CI, 4.8%-7.6%), representing 14.0 million adults (P < .001).
• The age-adjusted prevalence of an LDL-C level of at least 190 mg/dL declined from 3.8% (95% CI, 2.8%-5.2%), representing 6.6 million adults, to 2.1% (95% CI, 1.4%-3.0%), representing 4.8 million adults (P = .001).
• Among those with an LDL-C level of 160-189 mg/dL, the proportion of who were unaware and untreated declined from 52.1% to 42.7%, and among those with an LDL-C level of at least 190 mg/dL, it declined from 40.8% to 26.8%.
• Being unaware and untreated was more common in younger adults, men, racial and ethnic minority groups, those with lower educational attainment, those with lower income, and those without health insurance.

IN PRACTICE:

The lack of awareness and treatment of high LDL-C uncovered by the study “may be due to difficulties accessing primary care, low rates of screening in primary care, lack of consensus on screening recommendations, insufficient emphasis on LDL-C as a quality measure, and hesitance to treat asymptomatic individuals,” the authors concluded.

SOURCE:

The research was led by Ahmed Sayed, MBBS, faculty of medicine, Ain Shams University, Cairo, Egypt. It was published online in JAMA Cardiology.

LIMITATIONS:

The analysis was limited by a small number of participants with LDL-C levels of at least 190 mg/dL, possible nonresponse bias, and dependency on participant recall of whether LDL-C was previously measured. The inclusion of pregnant women may have influenced LDL-C levels.

DISCLOSURES:

Dr. Sayed has no relevant conflict of interest. The disclosures of the other authors are listed in the original publication.

GLASGOW – An interactive digital decision tool that individualizes menopause care received praise from primary care clinicians in the United Kingdom, who said it could improve patient care and streamline office visits.

The tool, called Wellspring, helps clarify menopause guidelines from the U.K.’s National Institute for Health and Care Excellence while fostering shared decision-making with evidence-based data.  

“Access to hormone replacement therapy [HRT], as well as decision-making around treatment for menopausal symptoms, is often complicated by concerns around its safety, and there is still a knowledge and a confidence gap among health care professionals causing reluctance to prescribe HRT,”  said Aini Kamal, MSc, from University College London. Ms. Kamal presented results of a survey about the tool at the annual meeting of the Royal College of General Practitioners.

For the study, Ms. Kamal, Daniel Reisel, MBBS, PhD, a gynecologist at UCL, and colleagues evaluated Wellspring with doctors, nurses, and pharmacists.

“Ensuring that women receive education around symptoms, so that they are empowered, is a key part of optimizing their care and sharing decision-making,” Dr. Reisel said in an interview. He added that U.K. primary care had seen an increase in cases of women presenting with symptoms associated with the perimenopause and menopause at a time when U.K. Members of Parliament are debating whether to make it mandatory for all women to have menopause check-up in their early 40s.

The online survey was completed by 280 participants, and respondents were primarily GPs with several years of relevant prescribing practice. Of those, 93% found information from national guidelines to be accurately presented in the tool, and 97% said they would recommend this decision aid to other health care professionals, Ms. Kamal reported.

Nearly all participants said they could see themselves using the tool with patients in the clinic or as an adjunct to virtual sessions. “This [finding] was particularly important because it demonstrates the clinical potential this tool has,” she said.

 

One consult, too many problems

Louise Newson, MBChB, who runs the U.K.’s largest menopause clinic, said primary care appointments are often time-pressured and follow a “’one problem-one consultation’” policy. As such, women are often thinking ‘Do I go with my joint pains, or my palpitations, tinnitus, or what?’ If a patient presents with tinnitus, a doctor might focus on the potential of an inner ear problem rather than a hormone deficiency, but I do know that if the woman is perimenopausal or menopausal, we often look to replace the missing hormones, and then if the tinnitus doesn’t improve we can revisit the ear problem.” 

Dr. Newson noted that 17% of women in her clinics have had more than six GP visits in the year before she sees them, but in the year following, this figure drops to 1%. Acknowledging that a menopause consultation for a GP is time-consuming, Dr. Newson pointed out that taking time initially with the patient “means it will reduce the number of future consultations quickly, but more importantly, we also know that taking HRT reduces long-term risk of serious diseases, including heart disease and osteoporosis.”

The digital tool can be used by both doctors and patients to help women work through their symptoms and equip them with knowledge so their GP visits are more productive.

“When we see women who are empowered with knowledge [about menopause symptoms], then the consultations are quicker and essentially place the patient central to the discussion,” Dr. Newson said.

Ed Russell-Smith, MBChB, a GP in Scotland who moderated the session, said the tool “lays out a nicely structured approach and provides modern treatment options and resources for patients.”

However, he added “we also need to remember there are potential harms to be done from HRT too. It’s vitally important that while patients might see HRT as a panacea, doctors need to balance this with the risks involved for each individual. As a tool, I think Wellspring can help us in this respect to apply general principles to that patient and individualize treatment.”

Dr. Reisel, Dr. Newson, Ms. Kamal, and Dr. Russell-Smith disclosed no relevant financial relationships. The Wellspring Decision Aid was supported by UCL’s Institute for Women’s Health. The Newson Health clinic is fully private, but research is done via the nonprofit arm, which is supported by the clinic. There is no pharma involvement.

The 10 best-selling liver health supplements on Amazon bring in an estimated $2.5 million each month. But none of them contain ingredients recommended by major groups of doctors who treat liver issues in the United States or Europe.

Like many supplements, popular online liver products are unregulated, meaning they do not have to meet the same safety and effectiveness standards as prescription medications. 

Sales of liver supplements are growing, particularly in the last few years, said Ahmed Eltelbany, MD, MPH, a first-year gastrointestinal fellow at the University of New Mexico. One reason could be increased alcohol use during the COVID-19 pandemic.

Some manufacturers make bold claims on Amazon, said Dr. Eltelbany, author of a study that looked into the supplements. “The most recurrent claims were that their supplements maintain normal liver function, are scientifically formulated, and – my personal favorite – are a highly effective liver detox formulation developed according to the latest scientific findings.”

While these claims might sound reassuring and scientifically grounded to an average consumer, he said, most of them are not backed up by rigorous clinical research.
 

Does natural mean safe?

Many supplements are marketed as “liver cleansing,” for “liver detox,” or for “liver support,” Dr. Eltelbany said as he presented the study results at the annual meeting of the American College of Gastroenterology. 

“People take these supplements because they believe they’re natural and therefore they’re safe,” said Paul Y. Kwo, MD, who moderated a session on the study at the meeting, when asked to comment. “As I tell every patient in clinic, a great white shark is natural, a scorpion is natural, and so is a hurricane. So just because they’re natural doesn’t mean they’re safe.”

At the same time, “it’s not that every supplement is bad for you. Nonetheless, there’s just a dizzying array of these out there” said Dr. Kwo, a professor of medicine at Stanford Medicine in Redwood, Calif.

“We have to be very cautious,” he said. For example, some people might believe that “if a little bit of a supplement is good, a tremendous amount must be really good.” The antioxidant turmeric, for example, has a pretty good safety record, he said. But this past year, some liver toxicity concerns arose about preparations with “very, very high concentrations” of turmeric. 
 

The top 10 sellers

Dr. Eltelbany and colleagues studied prices for 1-month supplies, monthly sales, and revenue for the top 10 liver supplements sold on Amazon on June 3, 2023:

Ranking by sales:

• 1. Liver Cleanse Detox & Repair Formula – Herbal Liver Supplement with Milk Thistle, Dandelion Root, Organic Turmeric and Artichoke Extract for Liver Health – Silymarin Milk Thistle Detox Capsules
• 2. Ancestral Supplements Grass Fed Beef Liver Capsules. Supports Energy Production, Detoxification, Digestion, Immunity and Full Body Wellness, Non-GMO, Freeze Dried Liver Health Supplement, 180 Capsules

• 10. Arazo Nutrition Liver Cleanse Detox & Repair Formula – Milk Thistle Herbal Support Supplement: Silymarin, Beet, Artichoke, Dandelion, Chicory Root

The investigators found a total of 65 unique ingredients. “Most of these ingredients have historical uses linked to liver health. But our research revealed that strong scientific evidence supporting the efficacy of any of these supplements is currently lacking,” Dr. Eltelbany said. They started the study by creating a new account on Amazon to make sure the search would not be influenced by prior shopping or purchases. They next searched for supplements using the keywords “liver” and “cleanse.” To figure out sales numbers, they used the AMZScout proprietary analytics software that Amazon sellers use to track sales. 
 

Reviewing the reviews

The researchers discovered an average 11,526 reviews for each supplement product. The average rating was 4.42 stars out of 5. 

Using Fakespot.com, proprietary Amazon customer review software that analyzes the timing and language of reviews, they found that only 65% of product reviews were genuine. 

“We felt it was crucial to vet the authenticity of customer feedback,” Dr. Eltelbany said.
 

Few other options?

Liver disease remains a persistent and significant global health burden. Despite advances in many areas of gastroenterology, there remains no curative treatment for liver cirrhosis, Dr. Eltelbany said. 

The primary option for people with end-stage liver disease is a liver transplant. “However, given the scarcity of donors and the vast number of patients in need, many individuals, unfortunately, do not get a timely transplant,” he said. “This void of treatment options and the desperation to find relief often drives patients towards alternative therapies.”

Also, online shopping has made getting these supplements “as simple as a click away. But what’s more concerning is the trust placed in these products by our patients,” Dr. Eltelbany said.

“There’s a strong need for rigorous scientific investigation into the actual health benefits of any liver detox supplements,” he said. “Above all, patient education remains paramount, warning them of potential risks and unknowns of these supplements.”

They next searched for supplements using the keywords “liver” and “cleanse.” To figure out sales numbers, they used the AMZScout proprietary analytics software that Amazon sellers use to track sales. 
 

Reviewing the reviews

The researchers discovered an average 11,526 reviews for each supplement product. The average rating was 4.42 stars out of 5. 

Using Fakespot.com, proprietary Amazon customer review software that analyzes the timing and language of reviews, they found that only 65% of product reviews were genuine. 

“We felt it was crucial to vet the authenticity of customer feedback,” Dr. Eltelbany said.
 

Few other options?

Liver disease remains a persistent and significant global health burden. Despite advances in many areas of gastroenterology, there remains no curative treatment for liver cirrhosis, Dr. Eltelbany said. 

The primary option for people with end-stage liver disease is a liver transplant. “However, given the scarcity of donors and the vast number of patients in need, many individuals, unfortunately, do not get a timely transplant,” he said. “This void of treatment options and the desperation to find relief often drives patients towards alternative therapies.”

Also, online shopping has made getting these supplements “as simple as a click away. But what’s more concerning is the trust placed in these products by our patients,” Dr. Eltelbany said.

“There’s a strong need for rigorous scientific investigation into the actual health benefits of any liver detox supplements,” he said. “Above all, patient education remains paramount, warning them of potential risks and unknowns of these supplements.”

The 10 best-selling liver health supplements on Amazon bring in an estimated $2.5 million each month. But none of them contain ingredients recommended by major groups of doctors who treat liver issues in the United States or Europe.

Like many supplements, popular online liver products are unregulated, meaning they do not have to meet the same safety and effectiveness standards as prescription medications. 

Sales of liver supplements are growing, particularly in the last few years, said Ahmed Eltelbany, MD, MPH, a first-year gastrointestinal fellow at the University of New Mexico. One reason could be increased alcohol use during the COVID-19 pandemic.

Some manufacturers make bold claims on Amazon, said Dr. Eltelbany, author of a study that looked into the supplements. “The most recurrent claims were that their supplements maintain normal liver function, are scientifically formulated, and – my personal favorite – are a highly effective liver detox formulation developed according to the latest scientific findings.”

While these claims might sound reassuring and scientifically grounded to an average consumer, he said, most of them are not backed up by rigorous clinical research.
 

Does natural mean safe?

Many supplements are marketed as “liver cleansing,” for “liver detox,” or for “liver support,” Dr. Eltelbany said as he presented the study results at the annual meeting of the American College of Gastroenterology. 

“People take these supplements because they believe they’re natural and therefore they’re safe,” said Paul Y. Kwo, MD, who moderated a session on the study at the meeting, when asked to comment. “As I tell every patient in clinic, a great white shark is natural, a scorpion is natural, and so is a hurricane. So just because they’re natural doesn’t mean they’re safe.”

At the same time, “it’s not that every supplement is bad for you. Nonetheless, there’s just a dizzying array of these out there” said Dr. Kwo, a professor of medicine at Stanford Medicine in Redwood, Calif.

“We have to be very cautious,” he said. For example, some people might believe that “if a little bit of a supplement is good, a tremendous amount must be really good.” The antioxidant turmeric, for example, has a pretty good safety record, he said. But this past year, some liver toxicity concerns arose about preparations with “very, very high concentrations” of turmeric.

A pair of new studies published about long COVID have shed more light on the sometimes-disabling condition that affects millions of people in the United States. 

Scientists worldwide have been working to understand the wide-ranging condition, from risk factors to causes to potential treatments. 

In the first study, 31 adults underwent lumbar puncture and blood draws to look for changes in their immune systems and also to look for changes in the nerve cells that could affect transmission of signals to the brain.

Among the participants, 25 people had neurocognitive symptoms of long COVID, such as memory loss or attention problems. Six participants had fully recovered from COVID, and 17 people had never had COVID. 

Those who had COVID were diagnosed between March 2020 and May 2021. Their fluid samples were drawn at least three months after their first symptoms.

The results were published in the Journal of Infectious Diseases. Study results showed that long COVID does not appear to be linked to the SARS-CoV-2 virus invading the brain or causing active brain damage.

According to a summary of the study from the University of Gothenburg (Sweden), where the researchers work, “there were no significant differences between the groups when analyzing blood and cerebrospinal fluid for immune activation or brain injury markers. The findings thus suggest that post-COVID condition is not the result of ongoing infection, immune activation, or brain damage.”

In the second study, Norwegian researchers compared the likelihood of having 17 different long COVID symptoms based on whether a person had been infected with COVID. The analysis included 53,846 people who were diagnosed with COVID between February 2020 and February 2021, as well as more than 485,000 people who were not infected. Most people had not been vaccinated against COVID-19 during the time of the study.

The results were published in the journal BMC Infectious Diseases. Study results showed that people who had COVID were more than twice as likely to experience shortness of breath or fatigue. They were also more likely to experience memory loss or headache compared to people who never had COVID. Researchers only looked at symptoms that occurred at least three months after a COVID diagnosis.

They also found that hospitalization increased the risk for experiencing long COVID symptoms of shortness of breath, fatigue, and memory loss.

The authors noted that a limitation of their study was that, often, not all symptoms reported during a visit with a general practice medical provider are recorded in Norway, which could have affected the results.

TOPLINE:

Atrial fibrillation (AF) is associated with a 45% increased risk of mild cognitive impairment (MCI), an outcome that’s linked to cardiovascular risk factors and multi-comorbidity, results of a new study suggest.

METHODOLOGY:

• From over 4.3 million people in the UK primary electronic health record (EHR) database, researchers identified 233,833 (5.4%) with AF (mean age, 74.2 years) and randomly selected one age- and sex-matched control person without AF for each AF case patient.
• The primary outcome was incidence of mild cognitive impairment (MCI).
• The authors adjusted for age, sex, year at study entry, socioeconomic status, smoking, and a number of comorbid conditions.
• During a median of 5.3 years of follow-up, there were 4,269 incident MCI cases among both AF and non-AF patients.

TAKEAWAY:

• Individuals with AF had a higher risk of MCI than that of those without AF (adjusted hazard ratio [aHR], 1.45; 95% confidence interval [CI], 1.35-1.56).
• Besides AF, older age (risk ratio [RR], 1.08) and history of depression (RR, 1.44) were associated with greater risk of MCI, as were female sex, greater socioeconomic deprivation, stroke, and multimorbidity, including, for example, diabetes, hypercholesterolemia, and peripheral artery disease (all P < .001).
• Individuals with AF who received oral anticoagulants or amiodarone were not at increased risk of MCI, as was the case for those treated with digoxin.
• Individuals with AF and MCI were at greater risk of dementia (aHR, 1.25; 95% CI, 1.09-1.42). Sex, smoking, chronic kidney disease, and multi-comorbidity were among factors linked to elevated dementia risk.

IN PRACTICE:

The findings emphasize the association of multi-comorbidity and cardiovascular risk factors with development of MCI and progression to dementia in AF patients, the authors wrote. They noted that the data suggest combining anticoagulation and symptom and comorbidity management may prevent cognitive deterioration.

SOURCE:

The study was conducted by Sheng-Chia Chung, PhD, Institute of Health informatics Research, University College London, and colleagues. It was published online Oct. 25, 2023, as a research letter in the Journal of the American College of Cardiology (JACC): Advances. 

LIMITATIONS:

The EHR dataset may have lacked granularity and detail, and some risk factors or comorbidities may not have been measured. While those with AF receiving digoxin or amiodarone treatment had no higher risk of MCI than their non-AF peers, the study’s observational design and very wide confidence intervals for these subgroups prevent making solid inferences about causality or a potential protective role of these drugs.

For some patients with atopic dermatitis (AD), dupilumab treatment can cause a benign reversible lymphoid reaction (LR) that mimics mycosis fungoides (MF) but differs histologically, according to a study published in JAMA Dermatology

The potential for such reactions requires diagnosing AD carefully, monitoring patients on dupilumab for new and unusual symptoms, and thoroughly working up suspicious LRs, according to an accompanying editorial and experts interviewed for this article.

“Dupilumab has become such an important first-line systemic medication for our patients with moderate to severe atopic dermatitis. It’s important for us to understand everything we can about its use in the real world – both good and bad,”Raj Chovatiya, MD, PhD, MSCI, assistant professor of dermatology at Northwestern University, Chicago, said in an interview. He was uninvolved with either publication.

Robert Sidbury, MD, MPH, added that, although the affected patient group was small, studying lymphoid reactions associated with dupilumab is important because of the risk for diagnostic misadventure that these reactions carry. He is a professor of pediatrics and division head of dermatology at Seattle Children’s Hospital and the University of Washington, Seattle.

“AD and MF are easily confused for one another at baseline,” explained Dr. Sidbury, who was not involved with the study or editorial. “Dupilumab is known to make AD better and theoretically could help MF via its effect on interleukin (IL)–13, yet case reports of exacerbation and/or unmasking of MF are out there.”

For the study, researchers retrospectively examined records of 530 patients with AD treated with dupilumab at the University Medical Center Utrecht (the Netherlands). Reviewing pretreatment biopsies revealed that among 14 (2.6%) patients who developed clinical suspicion of cutaneous T-cell lymphoma (CTCL) while on treatment, three actually had preexisting MF.

All 14 patients with LR initially responded to dupilumab then developed worsening symptoms at a median of 4 months. Patients reported that the worsening lesions looked and felt different than did previous lesions, with symptoms including burning/pain and an appearance of generalized erythematous maculopapular plaques, sometimes with severe lichenification, on the lower trunk and upper thighs.

The 14 patients’ posttreatment biopsies showed an atypical lymphoid infiltrate with lichenoid or perivascular distribution and intraepithelial T-cell lymphocytes. Whereas patients with MF had hyperconvoluted cerebriform lymphocytes aligned in the epidermal basal layer at the dermoepidermal junction, the 11 with LR had similar-looking lesions dispersed throughout the upper epidermis.

Immunohistochemically, both groups had a dysregulated (mostly increased) CD4:CD8 ratio. CD30 overexpression, usually absent in early-stage MF, affected only patients with LR and one patient with advanced MF. In addition, patients with LR maintained pan–T-cell antigens (CD2, CD3, and CD5), whereas those with MF did not. The 11 patients with LR experienced biopsy-confirmed resolution once they discontinued dupilumab.

It is reassuring that the LRs resolved after dupilumab discontinuation, writes the author of the accompanying editorial, Joan Guitart, MD, chief of dermatopathology at Northwestern University. Nevertheless, he added, such patients deserve “a comprehensive workup including skin biopsy with T-cell receptor clonality assay, blood cell counts with flow cytometry analysis, serum lactate dehydrogenase, and documentation of possible adenopathy, followed with imaging studies and/or local biopsies in cases with abnormal results.”

The possibility that these LRs may represent a first step toward lymphoma requires dermatologists to remain vigilant in ruling out MF, Dr. Guitart wrote, particularly in atypical presentations such as adult-onset AD, cases lacking a history of AD, and cases involving erythrodermic and other uncharacteristic presentations such as plaques, nodules, or spared flexural sites.

For dermatopathologists, Dr. Guitart recommended a cautious approach that resists overdiagnosing MF and acknowledging that insufficient evidence exists to report such reactions as benign. The fact that one study patient had both MF and LR raises concerns that the LR may not always be reversible, Dr. Guitart added.

Clinicians and patients must consider the possibility of dupilumab-induced LR as part of the shared decision-making process and risk-benefit calculus, Dr. Sidbury said. In cases involving unexpected responses or atypical presentations, he added, clinicians must have a low threshold for stopping dupilumab.

For patients who must discontinue dupilumab because of LR, the list of treatment options is growing. “While more investigation is required to understand the role of newer IL-13–blocking biologics and JAK inhibitors among patients experiencing lymphoid reactions,” said Dr. Chovatiya, “traditional atopic dermatitis therapies like narrowband UVB phototherapy and the oral immunosuppressant methotrexate may be reassuring in this population.” Conversely, cyclosporine has been associated with progression of MF.

Also reassuring, said Dr. Sidbury and Dr. Chovatiya, is the rarity of LR overall. Dr. Sidbury said, “The numbers of patients in whom LR or onset/exacerbation of MF occurs is extraordinarily low when compared to those helped immeasurably by dupilumab.”

Dr. Sidbury added that the study and accompanying editorial also will alert clinicians to the potential for newer AD biologics that target solely IL-13 and not IL-4/13, as dupilumab does. “If the deregulated response leading to LR and potentially MF in the affected few is driven by IL-4 inhibition,” he said, “drugs such as tralokinumab (Adbry), lebrikizumab (once approved), and perhaps other newer options might calm AD without causing LRs.”

(Lebrikizumab is not yet approved. In an Oct. 2 press release, Eli Lilly and Company, developer of lebrikizumab, said that it would address issues the U.S. Food and Drug Administration had raised about a third-party manufacturing facility that arose during evaluation of the lebrikizumab biologic license application.)

Study limitations include the fact that most patients who experienced LR had already undergone skin biopsies before dupilumab treatment, which suggests that they had a more atypical AD presentation from the start. The authors add that their having treated all study patients in a tertiary referral hospital indicates a hard-to-treat AD subpopulation.

Study authors reported relationships with several biologic drug manufacturers including Sanofi and Regeneron (dupilumab), LEO Pharma (tralokinumab), and Eli Lilly (lebrikizumab). However, none of these companies provided support for the study.

Dr. Sidbury has been an investigator for Regeneron, Pfizer, and Galderma and a consultant for LEO Pharma and Eli Lilly. Dr. Chovatiya has served as an advisor, consultant, speaker, and investigator for Sanofi and Regeneron. Dr. Guitart reported no conflicts of interest.

Nevertheless, he added, such patients deserve “a comprehensive workup including skin biopsy with T-cell receptor clonality assay, blood cell counts with flow cytometry analysis, serum lactate dehydrogenase, and documentation of possible adenopathy, followed with imaging studies and/or local biopsies in cases with abnormal results.”

The possibility that these LRs may represent a first step toward lymphoma requires dermatologists to remain vigilant in ruling out MF, Dr. Guitart wrote, particularly in atypical presentations such as adult-onset AD, cases lacking a history of AD, and cases involving erythrodermic and other uncharacteristic presentations such as plaques, nodules, or spared flexural sites.

For dermatopathologists, Dr. Guitart recommended a cautious approach that resists overdiagnosing MF and acknowledging that insufficient evidence exists to report such reactions as benign. The fact that one study patient had both MF and LR raises concerns that the LR may not always be reversible, Dr. Guitart added.

Clinicians and patients must consider the possibility of dupilumab-induced LR as part of the shared decision-making process and risk-benefit calculus, Dr. Sidbury said. In cases involving unexpected responses or atypical presentations, he added, clinicians must have a low threshold for stopping dupilumab.

For patients who must discontinue dupilumab because of LR, the list of treatment options is growing. “While more investigation is required to understand the role of newer IL-13–blocking biologics and JAK inhibitors among patients experiencing lymphoid reactions,” said Dr. Chovatiya, “traditional atopic dermatitis therapies like narrowband UVB phototherapy and the oral immunosuppressant methotrexate may be reassuring in this population.” Conversely, cyclosporine has been associated with progression of MF.

Also reassuring, said Dr. Sidbury and Dr. Chovatiya, is the rarity of LR overall. Dr. Sidbury said, “The numbers of patients in whom LR or onset/exacerbation of MF occurs is extraordinarily low when compared to those helped immeasurably by dupilumab.”

Dr. Sidbury added that the study and accompanying editorial also will alert clinicians to the potential for newer AD biologics that target solely IL-13 and not IL-4/13, as dupilumab does. “If the deregulated response leading to LR and potentially MF in the affected few is driven by IL-4 inhibition,” he said, “drugs such as tralokinumab (Adbry), lebrikizumab (once approved), and perhaps other newer options might calm AD without causing LRs.”

(Lebrikizumab is not yet approved. In an Oct. 2 press release, Eli Lilly and Company, developer of lebrikizumab, said that it would address issues the U.S. Food and Drug Administration had raised about a third-party manufacturing facility that arose during evaluation of the lebrikizumab biologic license application.)

Study limitations include the fact that most patients who experienced LR had already undergone skin biopsies before dupilumab treatment, which suggests that they had a more atypical AD presentation from the start. The authors add that their having treated all study patients in a tertiary referral hospital indicates a hard-to-treat AD subpopulation.

Study authors reported relationships with several biologic drug manufacturers including Sanofi and Regeneron (dupilumab), LEO Pharma (tralokinumab), and Eli Lilly (lebrikizumab). However, none of these companies provided support for the study.

Dr. Sidbury has been an investigator for Regeneron, Pfizer, and Galderma and a consultant for LEO Pharma and Eli Lilly. Dr. Chovatiya has served as an advisor, consultant, speaker, and investigator for Sanofi and Regeneron. Dr. Guitart reported no conflicts of interest.

For some patients with atopic dermatitis (AD), dupilumab treatment can cause a benign reversible lymphoid reaction (LR) that mimics mycosis fungoides (MF) but differs histologically, according to a study published in JAMA Dermatology

The potential for such reactions requires diagnosing AD carefully, monitoring patients on dupilumab for new and unusual symptoms, and thoroughly working up suspicious LRs, according to an accompanying editorial and experts interviewed for this article.

“Dupilumab has become such an important first-line systemic medication for our patients with moderate to severe atopic dermatitis. It’s important for us to understand everything we can about its use in the real world – both good and bad,”Raj Chovatiya, MD, PhD, MSCI, assistant professor of dermatology at Northwestern University, Chicago, said in an interview. He was uninvolved with either publication.

Robert Sidbury, MD, MPH, added that, although the affected patient group was small, studying lymphoid reactions associated with dupilumab is important because of the risk for diagnostic misadventure that these reactions carry. He is a professor of pediatrics and division head of dermatology at Seattle Children’s Hospital and the University of Washington, Seattle.

“AD and MF are easily confused for one another at baseline,” explained Dr. Sidbury, who was not involved with the study or editorial. “Dupilumab is known to make AD better and theoretically could help MF via its effect on interleukin (IL)–13, yet case reports of exacerbation and/or unmasking of MF are out there.”

For the study, researchers retrospectively examined records of 530 patients with AD treated with dupilumab at the University Medical Center Utrecht (the Netherlands). Reviewing pretreatment biopsies revealed that among 14 (2.6%) patients who developed clinical suspicion of cutaneous T-cell lymphoma (CTCL) while on treatment, three actually had preexisting MF.

All 14 patients with LR initially responded to dupilumab then developed worsening symptoms at a median of 4 months. Patients reported that the worsening lesions looked and felt different than did previous lesions, with symptoms including burning/pain and an appearance of generalized erythematous maculopapular plaques, sometimes with severe lichenification, on the lower trunk and upper thighs.

The 14 patients’ posttreatment biopsies showed an atypical lymphoid infiltrate with lichenoid or perivascular distribution and intraepithelial T-cell lymphocytes. Whereas patients with MF had hyperconvoluted cerebriform lymphocytes aligned in the epidermal basal layer at the dermoepidermal junction, the 11 with LR had similar-looking lesions dispersed throughout the upper epidermis.

Immunohistochemically, both groups had a dysregulated (mostly increased) CD4:CD8 ratio. CD30 overexpression, usually absent in early-stage MF, affected only patients with LR and one patient with advanced MF. In addition, patients with LR maintained pan–T-cell antigens (CD2, CD3, and CD5), whereas those with MF did not. The 11 patients with LR experienced biopsy-confirmed resolution once they discontinued dupilumab.

It is reassuring that the LRs resolved after dupilumab discontinuation, writes the author of the accompanying editorial, Joan Guitart, MD, chief of dermatopathology at Northwestern University. Nevertheless, he added, such patients deserve “a comprehensive workup including skin biopsy with T-cell receptor clonality assay, blood cell counts with flow cytometry analysis, serum lactate dehydrogenase, and documentation of possible adenopathy, followed with imaging studies and/or local biopsies in cases with abnormal results.”

Human insulin can be left unrefrigerated for much longer than previously thought, findings from a new Cochrane review suggest.

The review included 17 studies in 22 published articles and additional unpublished information from major insulin manufacturers. The data suggest it is possible to store unopened short- and intermediate-acting human insulin vials, pens/cartridges or prefilled plastic syringes at temperatures up to 25 °C (77 °F) for a maximum of 6 months and up to 37 °C (98.6 °F) for a maximum of 2 months without a clinically relevant loss of insulin potency.

Two studies found small decrements in potency at higher temperatures and/or longer durations unrefrigerated, but the rest did not.

This contrasts with current guidance and labeling that advises storing unopened human insulin at temperatures between 2 °C (35.6 °F) and 8°C (46.4 °F), necessitating refrigeration. Once the vial or pen cartridge is opened, the guidance is to store at “room temperature” and use within about 4-6 weeks.

The recommendations vary, however, and there is no clear consensus on how human insulin should be stored in settings where reliable refrigeration can’t be guaranteed, such as low-income countries, those affected by extreme heat, or areas of conflict or natural disasters. Such areas are home to growing numbers of people with diabetes, according to the Cochrane Database of Systematic Reviews report, published online.

The review also found that oscillating temperatures between 25 °C (77 °F) and 37 °C (98.6 °F), typical of daytime and nighttime fluctuations in tropical countries, for up to 3 months do not result in clinically relevant loss of insulin activity for short-acting, intermediate-acting, or mixed human insulin.   

“Our study opens up new possibilities for individuals living in challenging environments, where access to refrigeration is limited. By understanding the thermal stability of insulin and exploring innovative storage solutions, we can make a significant impact on the lives of those who depend on insulin for their well-being,” the study’s lead author, Bernd Richter, MD, of the Institute of General Practice, Medical Faculty of the Heinrich-Heine-University, Düsseldorf, Germany, said in a statement.

In addition, one small pilot clinical study showed that human insulin stored for 6 weeks in an unglazed clay pot with temperatures ranging between 25 °C (77 °F) and 27°C (80.6 °F) did not result in differences in plasma glucose–lowering in eight healthy volunteers, compared with refrigerator-stored insulin. “With the help of simple cooling devices for insulin storage such as clay pots, it is possible to effectively reduce high outside temperatures in many high-temperature regions of the world,” wrote Dr. Richter and colleagues Brenda Bongaerts, PhD, and Maria-Inti Metzendorf, also from Heinrich-Heine-University.

Asked to comment, Leonardo Scapozza, PhD, of the School of Pharmaceutical Sciences at the University of Geneva, Switzerland, said that these findings align with a study he published in 2021.   

“Indeed ... we have done a small-scale study by analyzing the insulin coming back from the field and showing that insulin potency and stability was conserved. An extended clinical study where the insulin is submitted to varying controlled condition is not possible and ethically debatable. But an extended study where patients are given a log tag to monitor their real storage condition and the remaining samples are collected back and sent back for analysis in a specialized lab would be very good to further confirm the [conclusions],” said Dr. Scapozza, who was not part of Dr. Richter’s team on this review. 

While the issue of insulin refrigeration is less urgent in higher-income countries, it does arise, as in situations where people accidentally leave their unopened insulin out of the refrigerator or when they carry backup insulin while traveling.

The Cochrane Review excluded studies of insulin analogs, used in most developed countries, but Dr. Scapozza’s study had included them. “We observed the same stability as the ones used in low-income countries.” He added that his data combined with those in the new report provide evidence that would make it “possible to better and optimally use the available insulin that is becoming more and more costly.”

Dr. Scapozza also told this news organization that after he presented his data to Médecins Sans Frontières (Doctors Without Borders), he heard from a collaborator with that group who has diabetes. “He always used his insulin for his own treatment when he was in the field working and his insulin pen was in his backpack or pocket and his treatment was working. After hearing the data, he was very happy because he got a scientific explanation why his treatment was working, whether he was in Switzerland or during his mission in the camps submitted to the same condition of storage as any other patient in low income countries.”

Dr. Richter and Dr. Scapozza report no relevant financial relationships.

Patients age 65 and older who receive thyroid hormone therapy and experience low thyrotropin are at increased risk for dementia and other cognitive problems, according to new research published in JAMA Internal Medicine.

The study found that these patients with thyrotoxicosis had a higher likelihood of incident cognitive disorder (adjusted hazard ratio, 1.39; 95% confidence interval, 1.18-1.64; P < .001). Broken down between internal and external causes of thyrotoxicosis, exogenous thyrotoxicosis continued to be a significant risk factor (aHR, 1.34: 95% CI, 1.10-1.63; P = .003), while endogenous thyrotoxicosis did not show a statistically significant risk estimates (aHR, 1.38; 95% CI, 0.96-1.98; P = .08).

The study also found that women were more likely to have low levels of thyrotropin (thyroid-stimulating hormone/TSH) than men and were more likely to be overtreated.

Previous studies looking at the correlation between hyperthyroidism and cognitive disorders often did not include participants who were already taking thyroid hormones, according to Jennifer S. Mammen, MD, PhD, assistant professor of medicine at the Asthma and Allergy Center at John Hopkins University, Baltimore, and the senior author of the study.

“The fact that we see the signal both in people who are being overtreated with thyroid hormone and in people who have endogenous hyperthyroidism is one way that we think that this supports the fact that it’s not just confounding, it’s not just bias,” Dr. Mammen said. “There’s two different sources of hyperthyroidism, and they’re both showing the same relationship.”

In the study, Dr. Mammen and colleagues analyzed electronic health records for patients aged 65 years and older who received primary care in the Johns Hopkins Community Physicians Network over a 10-year period starting in 2014. Patients had to have a minimum of two visits 30 days apart. None had a history of low TSH levels or cognitive disorder diagnoses within 6 months of their first doctor visit.

More than 65,000 patients were included in the study. Slightly more than half (56%) were female, almost 70% were White, 19.3% were Black, 4.6% were Asian, and 0.4% were American Indian. Almost 25,000 low TSH measurements among 2,710 patients were recorded during the study period. The majority of low TSH measurements were exogenous (14,875), followed by origins of unknown cause (5,833), and endogenous (4,159).

During the follow-up period, 7.2% (4,779) patients received a new cognitive disorder diagnosis, which was dementia in 77% of cases.

Dr. Mammen said primary care physicians should carefully consider whether thyroid hormone therapy is necessary for older patients, and, if so, great care should be taken to avoid overtreatment.

“This is yet another reason for us to be vigilant about not overtreating people with thyroid hormone, especially in older adults,” Dr. Mammen said. “We already know that atrial fibrillation rates are increased in people who are hyperthyroid. We know that fracture and osteoporosis is affected by hyperthyroidism. And now we also have an association with higher rates of cognitive disorders.”

Taking a cautious approach to prescribing thyroid hormone therapy for older patients is paramount, according to Jean Chen, MD, partner at Texas Diabetes & Endocrinology, who was not affiliated with the study.

“All medical providers need to be aware that the 65 and older population does not need to be treated as aggressively with their thyroid hormone,” Dr. Chen said. “We are finding more and more complications from overtreatment rather than benefit in this population.”

Often, older patients may complain of symptoms such as constipation, feeling cold, or tiredness, which can be symptoms of hypothyroidism. But these symptoms could also be from anemia, vitamin deficiencies, depression, perimenopause, menopause, insulin resistance, and sleep apnea. If necessary, Dr. Chen recommended primary care physicians consult with an endocrinologist regarding a possible treatment plan and making a differential diagnosis.

In addition, Dr. Chen said other studies have shown that treating patients with thyroid hormone either did not resolve the condition or negatively impacted anxiety, muscle strength, and bone density, or it increased the risk for arrhythmia. Therefore, it’s important to weight the risks versus the benefits.

“There’s so much gray zone here,” Dr. Chen said.

The study was supported by the Richman Family Precision Medicine Center of Excellence in Alzheimer’s Disease, the Richman Family Foundation, the Rick Sharp Alzheimer’s Foundation, the Sharp Family Foundation, among others. The work was also supported by grants from the National Institutes of Health. One coauthor reported personal fees from Karuna, MapLight Therapeutics, Axsome Therapeutics, GIA, GW Research Limited, Merck, EXCIVA, Otsuka, IntraCellular Therapies, and Medesis Pharma for consulting for treatment development in Alzheimer’s disease outside the submitted work. No other disclosures were reported.

The study found that these patients with thyrotoxicosis had a higher likelihood of incident cognitive disorder (adjusted hazard ratio, 1.39; 95% confidence interval, 1.18-1.64; P < .001). Broken down between internal and external causes of thyrotoxicosis, exogenous thyrotoxicosis continued to be a significant risk factor (aHR, 1.34: 95% CI, 1.10-1.63; P = .003), while endogenous thyrotoxicosis did not show a statistically significant risk estimates (aHR, 1.38; 95% CI, 0.96-1.98; P = .08).

The study also found that women were more likely to have low levels of thyrotropin (thyroid-stimulating hormone/TSH) than men and were more likely to be overtreated.

Previous studies looking at the correlation between hyperthyroidism and cognitive disorders often did not include participants who were already taking thyroid hormones, according to Jennifer S. Mammen, MD, PhD, assistant professor of medicine at the Asthma and Allergy Center at John Hopkins University, Baltimore, and the senior author of the study.

“The fact that we see the signal both in people who are being overtreated with thyroid hormone and in people who have endogenous hyperthyroidism is one way that we think that this supports the fact that it’s not just confounding, it’s not just bias,” Dr. Mammen said. “There’s two different sources of hyperthyroidism, and they’re both showing the same relationship.”

In the study, Dr. Mammen and colleagues analyzed electronic health records for patients aged 65 years and older who received primary care in the Johns Hopkins Community Physicians Network over a 10-year period starting in 2014. Patients had to have a minimum of two visits 30 days apart. None had a history of low TSH levels or cognitive disorder diagnoses within 6 months of their first doctor visit.

More than 65,000 patients were included in the study. Slightly more than half (56%) were female, almost 70% were White, 19.3% were Black, 4.6% were Asian, and 0.4% were American Indian. Almost 25,000 low TSH measurements among 2,710 patients were recorded during the study period. The majority of low TSH measurements were exogenous (14,875), followed by origins of unknown cause (5,833), and endogenous (4,159).

During the follow-up period, 7.2% (4,779) patients received a new cognitive disorder diagnosis, which was dementia in 77% of cases.

Dr. Mammen said primary care physicians should carefully consider whether thyroid hormone therapy is necessary for older patients, and, if so, great care should be taken to avoid overtreatment.

“This is yet another reason for us to be vigilant about not overtreating people with thyroid hormone, especially in older adults,” Dr. Mammen said. “We already know that atrial fibrillation rates are increased in people who are hyperthyroid. We know that fracture and osteoporosis is affected by hyperthyroidism. And now we also have an association with higher rates of cognitive disorders.”

Taking a cautious approach to prescribing thyroid hormone therapy for older patients is paramount, according to Jean Chen, MD, partner at Texas Diabetes & Endocrinology, who was not affiliated with the study.

“All medical providers need to be aware that the 65 and older population does not need to be treated as aggressively with their thyroid hormone,” Dr. Chen said. “We are finding more and more complications from overtreatment rather than benefit in this population.”

Often, older patients may complain of symptoms such as constipation, feeling cold, or tiredness, which can be symptoms of hypothyroidism. But these symptoms could also be from anemia, vitamin deficiencies, depression, perimenopause, menopause, insulin resistance, and sleep apnea. If necessary, Dr. Chen recommended primary care physicians consult with an endocrinologist regarding a possible treatment plan and making a differential diagnosis.

In addition, Dr. Chen said other studies have shown that treating patients with thyroid hormone either did not resolve the condition or negatively impacted anxiety, muscle strength, and bone density, or it increased the risk for arrhythmia. Therefore, it’s important to weight the risks versus the benefits.

“There’s so much gray zone here,” Dr. Chen said.

The study was supported by the Richman Family Precision Medicine Center of Excellence in Alzheimer’s Disease, the Richman Family Foundation, the Rick Sharp Alzheimer’s Foundation, the Sharp Family Foundation, among others. The work was also supported by grants from the National Institutes of Health. One coauthor reported personal fees from Karuna, MapLight Therapeutics, Axsome Therapeutics, GIA, GW Research Limited, Merck, EXCIVA, Otsuka, IntraCellular Therapies, and Medesis Pharma for consulting for treatment development in Alzheimer’s disease outside the submitted work. No other disclosures were reported.

Health care providers who give this year’s Moderna COVID-19 vaccine to children aged 6 months to 11 years should be sure they withdraw the correct volume of the vaccine from the vial to ensure a proper dose, the Food and Drug Administration said in a MedWatch issued Nov. 1, 2023.

That dose is 0.25 mL for children 6 months through 11 years. In the MedWatch, the FDA said that it “has become aware” that the single-dose vial for use in this age group “contains notably more than 0.25 mL of the vaccine.” It added: “Some healthcare providers may be withdrawing the entire contents of the vial to administer to an individual.”

The FDA revised the Fact Sheet for Healthcare Providers Administering Vaccine to clarify that the 0.25 mL should be withdrawn from the vial and that the vial and any excess then should be discarded. It is in a single-dose vial with a blue cap and a green label.

“It is common [for vaccine makers] to put in a little bit of extra vaccine just to make sure everyone gets enough,” said William Schaffner, MD, an infectious disease specialist at Vanderbilt University Medical Center, Nashville, Tenn. “The provider is supposed to be looking at the syringe when they withdraw it to make sure they get the right amount,” Dr. Schaffner said.

Recently, parents on social media had expressed concerns that their children may have gotten more than the recommended dose, with some parents noticing more reactions such as soreness and fever with the 2023-2024 vaccine dose than they did with their children’s previous COVID vaccinations.

“Since the beginning of the rollout, parents were telling us of cases where pharmacies accidentally gave their children a double dose, while doctors in our group were pointing out that their vials for children contained twice the amount than what was needed,” said Fatima Khan, a parent and cofounder of the group Protect Their Future, an organization that advocates for pediatric vaccine access. Members contacted the FDA and other officials. “We appreciate that the FDA took our concerns seriously and issued this safety update,” Ms. Khan said.

No safety risks identified

“The FDA has not identified any safety risks associated with administration of the higher dose in individuals 6 months through 11 years of age and no serious adverse events were identified related to a dosing error for the vaccine,” Cherie Duvall-Jones, an FDA spokesperson, said in an email response.

“The FDA received questions from stakeholders about the dosing issue on Oct. 29, and contacted Moderna to discuss and better understand the issue,” Ms. Duvall-Jones said. The agency then alerted health care providers via the safety communication and other means to be sure the correct dosage is given to the children aged 12 years or younger.
 

One parent’s experience

Jane Jih, MD, an internist in San Francisco, took her 7-year-old daughter to a pharmacy to get the vaccine, and it was the first time the pharmacist had given a pediatric dose. “We both had to double check the dose,” Dr. Jih said. She observed that the vial had about 0.40 mL, which is 0.15 mL above the recommended dose.

A few weeks later, Dr. Jih could access the vaccine for her nearly-3-year-old son. The nurse practitioner who administered it had been giving many pediatric Moderna shots, she said, “so I felt more confident in the second scenario.”
 

Perhaps more reactions, no danger

“If you get a little bit more [than the recommended 0.25 mL], that certainly is not going to harm the child,” Dr. Schaffner said. “There may be a little bit more local reaction. In terms of the child’s immune system, there really isn’t any harm.”

If an entire adult dose is mistakenly given, he said, “I think the reaction locally in some children may be more evident, they may get more sore arms, redness, maybe a little bit more swelling and tenderness. Fever is also a possibility, but “these vaccines have not been associated with too much fever.”

Could a double dose do more harm than that? “It is unknown,” said Aaron Glatt, MD, chief of infectious diseases and hospital epidemiologist for Mount Sinai South Nassau, Oceanside, N.Y. “But there is the theoretical potential for some more complications. I do not know whether this [excess vaccine] would cause an increased likelihood of cardiac inflammatory problems like myocarditis or other rare complications to occur more frequently.”

The message for health care providers giving the vaccine, Dr. Schaffner said, is: “Look at your syringe to make sure the dose is appropriate.”

The Food and Drug Administration has approved vonoprazan 10-mg and 20-mg tablets (Voquezna, Phathom Pharmaceuticals) for the healing and maintenance of all grades of erosive esophagitis, also known as erosive gastroesophageal reflux disease (GERD), as well as relief of associated heartburn, the company has announced.

Vonoprazan, an oral potassium-competitive acid blocker (PCAB), provides more potent inhibition of gastric acid than do proton pump inhibitors (PPIs) and is seen as a potential alternative.

The approval of vonoprazan for erosive GERD was based on results from the phase 3 PHALCON-EE study.

The randomized, double-blind, multicenter study enrolled 1,024 patients with erosive GERD in the United States and Europe and compared vonoprazan with the PPI lansoprazole (Prevacid) in the healing and maintenance of healing of erosive GERD and associated heartburn symptom relief.

Vonoprazan 20 mg was noninferior to lansoprazole 30 mg for complete healing by week 8 in patients with all grades of erosive GERD, with healing rates of 93% vs. 85% for lansoprazole.

In addition, vonoprazan showed superior rates of healing in patients with moderate to severe disease (LA Grade C/D) at week 2 (70% vs. 53% with lansoprazole). Vonoprazan was also noninferior to lansoprazole in terms of heartburn-free days over the healing period.

In the maintenance phase of the trial, vonoprazan 10 mg was superior to lansoprazole 15 mg in maintaining healing at 6 months in all patients who were randomly assigned (79% vs. 72%) and in the subset of patients with moderate to severe erosive GERD (75% vs. 61%).

Adverse event (AE) rates for vonoprazan were comparable to lansoprazole. The most common AEs in the healing phase (≥ 2% with vonoprazan) were gastritis, diarrhea, abdominal distention, abdominal pain, and nausea.

The most common AEs in the maintenance phase (≥ 3% with vonoprazan) were gastritis, abdominal pain, dyspepsia, hypertension, and urinary tract infection.

“For many GERD patients with erosive esophagitis, the response to current treatment is suboptimal, leaving them with incomplete healing and ongoing symptoms,” Colin W. Howden, MD, professor emeritus, University of Tennessee, Memphis, said in the news release.

Vonoprazan provides clinicians with a “new first-in-class therapeutic option that demonstrated faster healing in the more difficult-to-treat GERD patients with erosive esophagitis,” Dr. Howden added.

Vonoprazan is expected to be available in the United States in December.

The FDA also recently approved reformulated vonoprazan tablets for Voquezna Triple Pak (vonoprazan, amoxicillin, clarithromycin) and Voquezna Dual Pak (vonoprazan, amoxicillin) for the treatment of Helicobacter pylori infection in adults, Phathom Pharmaceuticals announced.

In February, the FDA had put both the vonoprazan new drug application for erosive esophagitis and the postapproval supplement for H. pylori on hold until the company addressed concerns over the presence of nitrosamine impurities.
