Asymptomatic adults, teens, and pregnant women with no known history or symptoms of herpes infection need not undergo routine screening, according to the latest recommendation from the U.S. Preventive Services Task Force.

The 2023 recommendation reaffirms the conclusion from 2016, wrote Carol M. Mangione, MD, of the University of California, Los Angeles, and members of the task force.

“Currently, routine serologic screening for genital herpes is limited by the low predictive value of the widely available serologic screening tests and the expected high rate of false-positive results likely to occur with routine screening of asymptomatic persons in the U.S.,” the authors said.

In the recommendation, published in JAMA, the authors affirmed with moderate certainty and a grade D recommendation that the risks of routine screening for herpes simplex virus (HSV) in asymptomatic individuals outweigh the benefits.

The task force found no new evidence on the accuracy of serologic screening tests, the benefits of early detection and treatment, or on the harms of screening and treatment since the 2016 review of 17 studies in 19 publications, with data from more than 9,000 individuals.

Studies of the accuracy of serologic screening for herpes simplex virus-2 in the 2016 report mainly reflect populations with higher HSV-2 prevalence and are of limited applicability to the U.S. primary care population, the authors wrote. Evidence from the 2016 review also showed limited and inconsistent support for the early identification and treatment of HSV-2 in asymptomatic individuals, including those who were pregnant.

No new evidence has emerged since 2016 regarding harms of screening or treating genital herpes in asymptomatic individuals, the authors noted. “Based on previous evidence, the USPSTF estimated that using the widely available serologic tests for HSV-2, nearly 1 of every 2 diagnoses in the general U.S. primary care population could be false,” they said. The task force also concluded that the low accuracy of the current tests could prompt unnecessary treatment for individuals with false-positive diagnoses, as well as social and emotional harm for these individuals.

During a period of public comment from Aug. 16, 2022, to Sept. 12, 2022, individuals expressed concerns that the recommendation against routine screening showed a disinclination to take herpes seriously, and concerns that asymptomatic individuals could transmit the infection to sexual partners, the authors said. However, the estimated seroprevalence of HSV-1 and HSV-2 has declined in recent decades, and other comments supported the USPSTF’s analysis of the evidence and noted their consistency with current clinical practice.

The task force noted that research gaps remain and recognized the need to improve screening and treatment of genital herpes to prevent symptomatic episodes and transmission. Specifically, the USPSTF recommendation calls for more research to assess the accuracy of screening tests, to enroll more study participants from populations disproportionately affected by HSV, to examine the effect of behavioral counseling, and to clarify associations between HSV and pregnancy outcomes. In addition, the task force called for research to create an effective vaccine to prevent genital HSV infection and to develop a cure.
 

Targeted screening makes sense for now

“Given the frequency and severity of the range of diseases seen with HSV and the large proportion of persons who are asymptomatic, identifying carriers through type-specific serologic screening has long been considered a plausible strategy,” Mark D. Pearlman, MD, of the University of Michigan, Ann Arbor, wrote in an accompanying editorial.

However, accuracy of the currently available serology screening tests is low, and the adverse social and psychological effects and the impact on relationships for many asymptomatic individuals who test positive and may be incorrectly identified as infected remains a concern, said Dr. Pearlman.

Although some may be disagree about the value of routine serotesting for HSV-2 in asymptomatic individuals, other strategies can reduce the spread of infection and help those infected, he said.

Many experts continue to recommend targeted serotesting to high-risk populations, such as pregnant women whose nonpregnant partner is known to have genital or oral herpes and whose own infection status or serostatus is uncertain, said Dr. Pearlman. Other targeted strategies include screening individuals with recurrent or atypical genital symptoms and negative polymerase chain reaction assay or culture results, a clinical herpes diagnosis without laboratory confirmation, or those at increased risk because of a high number of sexual partners or a history of HIV infection, he said.

“Of note, the current CDC STI guidelines and ACOG both concur with the USPSTF that routine screening in the general population or routine screening during pregnancy are not recommended,” Dr. Pearlman said. Meanwhile, research efforts continue to help reduce the impact of HSV disease and development of a more effective testing methodology “might tip the balance in favor of routine screening” in the future, he emphasized.

The recommendations were supported by the Agency for Healthcare Research and Quality. The members of the task force received reimbursement for travel and an honorarium but had no other relevant financial conflicts to disclose. Dr. Pearlman had no financial conflicts to disclose.

When administered subcutaneously every 2 weeks, secukinumab was effective at improving signs and symptoms of moderate to severe hidradenitis suppurativa (HS) in adults up to 52 weeks, results from two pivotal phase 3 clinical trials showed.

The findings build on week 16 data from two trials – SUNSHINE and SUNRISE – that investigated the efficacy, safety, and tolerability of the interleukin-17A inhibitor secukinumab (Cosentyx) versus placebo in the treatment of moderate to severe HS, and were presented at the 2022 annual congress of the European Academy of Dermatology and Venereology. In those studies, at 16 weeks, 42%-46% of patients achieved an HS Clinical Response (HiSCR) – the primary outcome measure in both trials. For the most recent analysis, which was published in The Lancet, investigators found that, at 52 weeks, 56.4% of patients in SUNSHINE and 65% of patients in SUNRISE who received secukinumab 300 mg every 2 weeks achieved a HiSCR, compared with 56.3% of patients in SUNSHINE and 62.2% of patients in SUNRISE who received secukinumab 300 mg every 4 weeks.

“This is great news for people with HS: it improves our knowledge about how to best treat patients today and leads us to new areas that will help us treat them even better in the future,” Alexa B. Kimball, MD, MPH, the lead investigator for both trials, said in an interview. “Dermatologists have been using biologics for decades. This data provides clinicians with information they can use to easily expand their HS management repertoire to include secukinumab.”

To date, the tumor necrosis factor inhibitor adalimumab is the only approved biologic therapy approved for the treatment of moderate-to-severe HS, in people aged 12 years and older.

The two trials were conducted in 40 countries, with SUNSHINE enrolling 541 patients, and SUNRISE enrolling 543. Patients in each study were randomized to one of three experimental arms: secukinumab 300 mg every 2 weeks after five weekly loading doses; secukinumab 300 mg every 4 weeks after five weekly loading doses; placebo dose every 2 weeks after five weekly placebo doses. The mean age was 37 years, about 55% were female, and about 76% were White (about 9% were Black and about 10% were Asian). Dr. Kimball, investigator at Beth Israel Deaconess Medical Center and professor of dermatology at Harvard Medical School, Boston, and coauthors observed that the group that received secukinumab every 4 weeks did not meet the primary endpoint in the SUNSHINE trial, but it was met in the SUNRISE trial. “Research and subgroup analyses are required and might improve our understanding of the effect of patient characteristics on treatment response and further refine the dosing recommendations for different populations,” they wrote.

In a pooled analysis, 55.2% of patients from SUNSHINE and SUNRISE who received secukinumab 300 mg every 2 weeks had a reduction in pain as measured by the Patient’s Global Assessment of Skin Pain Numeric Rating Scale, compared with 53% of patients from SUNSHINE and SUNRISE who received secukinumab 300 mg every 4 weeks. The most common adverse events up to week 16 in both trials were headache, nasopharyngitis, and hidradenitis; no deaths occurred.

“One limitation of most studies in HS is that the placebo-controlled period is short, so the data obtained after that time is harder to interpret,” Dr. Kimball said in an interview. “In my experience, optimizing treatment can take almost a year and I hope we will see longer controlled periods in future studies.” Another limitation of the studies she acknowledged was a modest imbalance with respect to disease severity between the treatment groups at baseline. “It was a little surprising that some imbalances in the characteristics of randomized subjects in different arms of the study impacted efficacy levels,” she said. “We’ll need to continue to identify how to match patients and dosing regimens to get the best results.”

According to a press release from Novartis, trial results have been submitted to regulatory authorities in Europe and the United States, and decisions are expected in 2023. If approved, secukinumab will be the first and only IL-17 inhibitor for the treatment of moderate to severe HS.

Adam Friedman, MD, professor and chair of dermatology at George Washington University, Washington, described HS as “an extraordinarily disabling, painful, deforming condition for which we only have one [Food and Drug Administration]–approved systemic therapy, requiring us to wear our ‘off-label bandit’ name tags proudly to tackle therapeutic challenges.

“Anecdotally,” he said, “we dabble with off-label biologics indicated for psoriasis in this setting, though limitations exist ranging from lack of large-scale clinical data to the recurring theme that psoriasis dosing typically doesn’t cut it, making access to said medications even more difficult. Investigators in this study addresses both gaps very effectively, and I for one welcome the implications and hopeful regulatory impact with open arms.”

The study was funded by Novartis. Dr. Kimball disclosed numerous conflicts of interest from various pharmaceutical companies. Dr. Friedman reported financial relationships with Sanova, Pfizer, Novartis, and other companies.

SAN DIEGO – According to the latest American Cancer Society (ACS) data, cutaneous melanoma was the 5th most common cancer in 2022, with an estimated 99,780 new cases and 7,650 deaths, following cancer of the colorectal area, lung and bronchus, prostate, and breast.

“The incidence of melanoma seems to have continued to go up since the early 1990s,” David E. Kent, MD, a dermatologist who practices in Macon, Ga., said at the annual Cutaneous Malignancy Update. “The death rates have been flat and may have slightly decreased.”

In 2023, the ACS estimates that about 97,610 new melanomas will be diagnosed in the United States (58,120 men and 39,490 women), and about 7,990 people are expected to die of melanoma (5,420 men and 2,570 women). In addition, ACS data from 2017-2019 project that about 2.1% of men and women will be diagnosed with cutaneous melanoma in their lifetime. To date, more than 1.3 million people in the United States live with cutaneous melanoma, and the overall 5-year survival is 93.7%.

Epidemiologic studies show an increase in melanoma incidence, primarily among White populations. “This is believed to be due primarily to sun exposure and to changing recreational behaviors and tanning bed exposures,” said Dr. Kent, who holds a faculty position in the department of dermatology at the Medical College of Georgia, Augusta. Increased surveillance and diagnosis also play a role. In the medical literature, annual increases in melanoma incidence vary from 3% to 7% per year, “which translates into a doubling of rates every 10-20 years,” he said, noting that annual melanoma costs are approximately $3.3 billion.

While incidence rates are lower in non-White, non-Hispanic populations, poor outcomes are disproportionately higher in persons of color. Blacks present at diagnosis with more advanced stage disease and are 1.5 times more likely to die from melanoma, he said, while Hispanics are 2.4 times more likely to present with stage III disease and 3.6 times more likely to have distant metastases. Persons of color also have higher rates of mucosal, acral lentiginous, and subungual melanoma.

Known genetic risk factors for melanoma include having skin types I and II, particularly those with light hair, light eyes, and freckling, and those with a family history have a twofold increased risk. Also, up to 40% of genetic cases are from inherited mutations in CDKN2A, CDK4, BAP1, and MCR1. Other genetic-related risk factors include the number and size of nevi, having atypical nevus syndrome, DNA repair defects, large congenital nevi, and a personal history of melanoma.

The main environmental risk factor for melanoma is exposure to ultraviolet radiation. “You can break it down in terms of whether this exposure is lifetime, intermittent intense UV exposure, from the use of tanning beds, or due to sunburns during childhood,” Dr. Kent said at the meeting, which was hosted by Scripps MD Anderson Cancer Center. Other environmental risk factors include distance from the equator, having a high socioeconomic status, being immunosuppressed, and exposure to heavy metals, insecticides, or hormones.

In a recently published study, researchers investigated the risk factors associated with first and second primary melanomas in 38,845 patients who were followed in Australia between 2011 and 2018. During a median follow-up of 7.4 years, 1,212 patients (3.1%) had a single primary melanoma diagnosis and 245 (0.6%) had a secondary primary melanoma diagnosis. The researchers found that second melanomas were more likely than were first melanomas to be in situ; for invasive tumors, second melanomas were more likely to be thin (defined as 1 mm or less) than were first melanomas.

In addition, having many self-reported moles at age 21 years was more strongly associated with second melanomas compared with first melanomas (hazard ratio [HR], 6.36 vs. 3.46, respectively; P = .01), as was having a high genetic predisposition (HR, 3.28 vs. 2.06; P = .03).

Second melanomas were also more strongly associated with a history of multiple skin cancer excisions than were first melanomas (HR, 2.63 vs. 1.86; P = .05). “Interestingly, there were no differences in UV exposure between the first primary and second primary melanoma groups,” said Dr. Kent, who was not involved with the study.

He noted that while sunscreen use protects against melanoma, a National Ambulatory Medical Care Survey (NAMCS) found that internists and pediatricians mentioned sunscreen at fewer than 0.1% of visits – even those with patients who have a diagnosis of skin disease. “Physicians need to do better,” he said. “We as dermatologists have work to do to help educate them.”

Dr. Kent reported having no relevant disclosures.

In 2023, the ACS estimates that about 97,610 new melanomas will be diagnosed in the United States (58,120 men and 39,490 women), and about 7,990 people are expected to die of melanoma (5,420 men and 2,570 women). In addition, ACS data from 2017-2019 project that about 2.1% of men and women will be diagnosed with cutaneous melanoma in their lifetime. To date, more than 1.3 million people in the United States live with cutaneous melanoma, and the overall 5-year survival is 93.7%.

Epidemiologic studies show an increase in melanoma incidence, primarily among White populations. “This is believed to be due primarily to sun exposure and to changing recreational behaviors and tanning bed exposures,” said Dr. Kent, who holds a faculty position in the department of dermatology at the Medical College of Georgia, Augusta. Increased surveillance and diagnosis also play a role. In the medical literature, annual increases in melanoma incidence vary from 3% to 7% per year, “which translates into a doubling of rates every 10-20 years,” he said, noting that annual melanoma costs are approximately $3.3 billion.

While incidence rates are lower in non-White, non-Hispanic populations, poor outcomes are disproportionately higher in persons of color. Blacks present at diagnosis with more advanced stage disease and are 1.5 times more likely to die from melanoma, he said, while Hispanics are 2.4 times more likely to present with stage III disease and 3.6 times more likely to have distant metastases. Persons of color also have higher rates of mucosal, acral lentiginous, and subungual melanoma.

Known genetic risk factors for melanoma include having skin types I and II, particularly those with light hair, light eyes, and freckling, and those with a family history have a twofold increased risk. Also, up to 40% of genetic cases are from inherited mutations in CDKN2A, CDK4, BAP1, and MCR1. Other genetic-related risk factors include the number and size of nevi, having atypical nevus syndrome, DNA repair defects, large congenital nevi, and a personal history of melanoma.

The main environmental risk factor for melanoma is exposure to ultraviolet radiation. “You can break it down in terms of whether this exposure is lifetime, intermittent intense UV exposure, from the use of tanning beds, or due to sunburns during childhood,” Dr. Kent said at the meeting, which was hosted by Scripps MD Anderson Cancer Center. Other environmental risk factors include distance from the equator, having a high socioeconomic status, being immunosuppressed, and exposure to heavy metals, insecticides, or hormones.

In a recently published study, researchers investigated the risk factors associated with first and second primary melanomas in 38,845 patients who were followed in Australia between 2011 and 2018. During a median follow-up of 7.4 years, 1,212 patients (3.1%) had a single primary melanoma diagnosis and 245 (0.6%) had a secondary primary melanoma diagnosis. The researchers found that second melanomas were more likely than were first melanomas to be in situ; for invasive tumors, second melanomas were more likely to be thin (defined as 1 mm or less) than were first melanomas.

In addition, having many self-reported moles at age 21 years was more strongly associated with second melanomas compared with first melanomas (hazard ratio [HR], 6.36 vs. 3.46, respectively; P = .01), as was having a high genetic predisposition (HR, 3.28 vs. 2.06; P = .03).

Second melanomas were also more strongly associated with a history of multiple skin cancer excisions than were first melanomas (HR, 2.63 vs. 1.86; P = .05). “Interestingly, there were no differences in UV exposure between the first primary and second primary melanoma groups,” said Dr. Kent, who was not involved with the study.

He noted that while sunscreen use protects against melanoma, a National Ambulatory Medical Care Survey (NAMCS) found that internists and pediatricians mentioned sunscreen at fewer than 0.1% of visits – even those with patients who have a diagnosis of skin disease. “Physicians need to do better,” he said. “We as dermatologists have work to do to help educate them.”

Dr. Kent reported having no relevant disclosures.

Patients with persistent upper-back itch from notalgia paresthetica may get some relief with oral difelikefalin, phase 2 data from a randomized, double-blinded placebo-controlled trial suggest.

However, side effects were significant and caused 19% in the intervention group to discontinue the trial versus 6% in the placebo group.

Results of the study were published online in the New England Journal of Medicine.

There is currently no treatment approved by the U.S. Food and Drug Administration for the common condition, which typically causes itch in the hard-to-reach area between the shoulder blades or mid-back.
 

Drug reduced moderate to severe itch

Difelikefalin – a selective kappa-opioid receptor agonist – is  FDA approved only as an injection for treating moderate to severe itch from chronic kidney disease in adults undergoing hemodialysis, and is marketed as Korsuva for that indication.

However, in a new trial, led by Brian S. Kim, MD, professor of dermatology and vice chair of research at the Icahn School of Medicine at Mount Sinai, New York, the drug gave moderate relief to patients with notalgia paresthetica who had moderate to severe itch.

Patients were randomly assigned 1:1 to receive oral difelikefalin 2 mg or a placebo twice daily for 8 weeks. The primary outcome was change in the weekly average of the daily 0-10 Worst Itch Numeric Rating Scale, for which 0 is “no itch” and 10 is “worst itch imaginable.”

Secondary clinical outcomes were itch-related quality-of-life and itch-related sleep measures.

The study included 126 patients; 62 received difelikefalin and 63 received placebo. One patient assigned to the difelikefalin group withdrew consent before the first dose.

The average baseline score on the Worst Itch scale was 7.6 (severe itch) in each group. Mean scores in the difelikefalin dropped by 4 points versus 2.4 points in the placebo group (95% confidence interval, −2.6 to −0.6; P = .001).

Difelikefalin did not help with sleep disturbance, compared with placebo, “except possibly in patients with impaired sleep at baseline,” the authors write. “Larger and longer trials are required to determine the effect and risks of difelikefalin treatment in this disorder.”

In a Mount Sinai press release, Dr. Kim, who is also director of the Lebwohl Center for Neuroinflammation and Sensation at Mount Sinai, called the team’s findings “encouraging.”

“The encouraging results achieved in this trial could reenergize the field and mark an important step toward improving symptoms of itch for patients with notalgia paresthetica,” he said.

Side effects ‘worrisome’

The main side effects reported included headaches, dizziness, constipation and increased urine output.

Shawn Kwatra, MD, director of the Johns Hopkins Itch Center, Baltimore, told this news organization that dizziness was “especially worrisome,” noting the average age of participants in the trial was 59-60 years. “We are very concerned about folks having falls or hip fractures,” he said.

“Things we use more commonly are topical steroids, topical capsaicin, the capsaicin patch, muscle strengthening, and gabapentin,” Dr. Kwatra said. “Off-label we use botulinum toxin (Botox) as well. I’m able to control” almost all of my notalgia paresthetica patients, he added.

In his view, for this type of drug, he said, “the right home for it is more for a generalized neuropathic pruritus or nociplastic itch vs. something very localized which is more amenable to topical therapies.”

He said that the associated central nervous system effects, such as dizziness and headache, “would limit therapeutic use to only the most severe cases in my mind.”

The trial was funded by Cara Therapeutics, manufacturer of difelikefalin.

Dr. Kim and coauthor Mark Lebwohl, MD, are paid consultants/advisers to Cara Therapeutics. Other coauthors also reported ties to Cara. Dr. Kwatra previously had done consulting work for Cara Therapeutics and is an advisory board member/consultant for AbbVie, Amgen, Arcutis Biotherapeutics, Aslan Pharmaceuticals, Castle Biosciences, Celldex Therapeutics, Galderma, Genzada Pharmaceuticals, Incyte Corporation, Johnson & Johnson, Leo Pharma, Novartis Pharmaceuticals Corporation, Pfizer, Regeneron Pharmaceuticals, and Sanofi and has served as an investigator for Galderma, Incyte, Pfizer, and Sanofi.

The prevalence of contact allergy triggered by a common product preservative, isothiazolinone, has decreased in Europe while it has increased in North America, a trend that is likely driven by regulatory differences, a retrospective cohort study suggests.

“Between 2009 to 2018, the global burden of isothiazolinone allergy showed divergent trends between North American and European countries,” lead study author Margo J. Reeder, MD, of the University of Wisconsin in Madison and her colleagues write. The study was published online in JAMA Dermatology.

Isothiazolinone contact allergy peaked in Europe in 2013-2014 before gradually decreasing, they found. The prevalence of isothiazolinone allergy steadily increased in North America during the study period. “Earlier and more stringent regulation of MI [methylisothiazolinone] in Europe is associated with these divergent trends,” they write.
 

Common ingredients worldwide

Isothiazolinone preservatives, which are added to personal and industrial products, cause allergic contact dermatitis worldwide, the authors write. The preservatives are found in a wide range of leave-on and rinse-off water-based personal care products, such as shampoo and other hair products, dishwashing liquid, face cream, body lotion, shower gel, liquid soap, and wet wipes, as well as in water-based paint.

A mixture of methylchloroisothiazolinone (MCI) and MI has been used to prevent microbial growth in products since the 1980s. In 2005, U.S. and European regulators approved MI alone at higher concentrations as a preservative in personal care products. Coupled with consumer concerns about other preservatives, such as parabens (a rare allergen), use of MI in personal care products increased, the authors write.

Subsequently, researchers reported a global increase in the prevalence of contact allergy to isothiazolinones, the authors write. Regulatory restrictions on MI in personal care products were implemented in 2013 in Europe and in 2015 in Canada but not in the United States.
 

Patch test data reveal latest trends

To compare prevalence trends of allergic contact allergy to MI and sensitization to the MCI/MI mixture in North America and in Europe, Dr. Reeder and her colleagues compared the prevalence of positive patch test reactions to MCI/MI and to MI alone in North America and in Europe between 2009 and 2018.

They analyzed data from the North American Contact Dermatitis Group (NACDG), the European Surveillance System on Contact Allergies (ESSCA), and the Information Network of Departments of Dermatology (IVDK) in 2-year intervals. The data came from patients who had been patch tested at referral patch test clinics in North America and Europe.

Over the decade, the study sites conducted patch testing for 226,161 patients for MCI/MI and 118,779 for MI. Most data came from Europe. The researchers found the following:

• In Europe, isothiazolinone allergy peaked in 2013 and 2014; MCI/MI positivity reached 7.6% (ESSCA) and 5.4% (IVDK) before decreasing to 4.4% (ESSCA) and 3.2% (IVDK) in 2017-2018.
• In North America, MCI/MI positivity rose steadily from 2.5% in 2009-2010 to 10.8% in 2017-2018.
• In Europe, there were 5.5% (ESSCA) and 3.4% (IVDK) positive reactions to MI, compared with 15% (NACDG) in North America in 2017-2018.

Divergent contact allergy trends linked to regulatory approaches

The downward trend of isothiazolinone allergy in Europe after its peak in 2013 and 2014 may have been due in part, the authors explain, to a memo released in 2013 by Cosmetics Europe after it and the European Society of Contact Dermatitis reviewed reports of increased contact allergy to MI. The memo urged companies to remove MI from leave-on products.

Later that year, the European Union’s Scientific Committee on Consumer Safety advised omitting MI from leave-on consumer personal care products and moved to restrict the ingredient in rinse-off products to less than 15 ppm. The recommendation took effect in 2015.

That year, Canada banned the use of MCI/MI in leave-on products but allowed MI alone in leave-on products until 2018. The total concentration of MI and MCI in wash-off products was limited to less than 15 ppm.

The authors add that, to their knowledge, the U.S. government does not restrict the use of MCI/MI or MI.
 

Policy implications for contact allergy

MI is still widely used in “countless products,” including shampoos, skin cleansers, dishwashing and laundry detergents, paints, and adhesives, Daniel W. Shaw, MD, associate professor of dermatology at the University of California, San Diego, told this news organization by email.

“Exact figures between the U.S. and Europe are difficult to compare due to differing patch test concentrations, but the overall trends strongly suggest that stricter and earlier regulation in Europe resulted in lower MI allergy prevalence there than in the U.S.,” added Dr. Shaw, who was not involved in the study.

Steven R. Feldman, MD, PhD, professor of dermatology at Wake Forest University in Winston-Salem, N.C., said by email that accurate information on allergic reaction prevalence is difficult to find.

“The NACDG, ESSCA, and IVDK databases may contain the best data available, but the data depend on people who get patch tested and are not directly informative of the allergy rates in the general population,” added Dr. Feldman, who was not involved in the study.

“The great majority of people in the population may not be allergic,” he said. “For those with itchy rashes, getting patch tested or avoiding products with preservatives may be prudent. Broad regulations, however, should consider the overall risks and benefits in the population, and this particular study does not fully capture those issues.”

“This study shows that government regulations are important to limit consumer exposure to common allergens, especially to the concentrations used in personal care products,” Kelly Tyler, MD, associate professor of dermatology at the Ohio State University Wexner Medical Center in Columbus, noted by email. She was not involved in the study.

She advised clinicians to ask their patients who may have allergic contact dermatitis whether they have been exposed to products containing these compounds.

“All personal care products in the store contain preservatives, and their maximum concentrations should be limited,” she advised. “The Expert Panel for Cosmetic Ingredient Safety should establish stricter guidelines for MI use in personal care products, especially given the findings of this study.”
 

Has MI contact allergy in North America peaked?

“In the U.S., MI has not been banned from leave-on skin-care products, but recently, its use has markedly decreased,” Dr. Shaw commented. “Hopefully, the prevalence of MI contact allergy will also begin to decrease.”

New evidence is promising. In a related study published online in Dermatology, Joel G. DeKoven, MD, MHSc, FRCPC, of the University of Toronto and his colleagues reported the NACDG 2019-2020 patch test results for MI in North America. They found that 13.8% of patients tested positive for MI.

“For the first time, MI positivity did not increase between reporting periods,” they conclude. “The epidemic of MI contact allergy in North America may have reached a plateau.”

Information regarding funding for the study was not provided. Dr. Reeder has financial relationships with the American Contact Dermatitis Society and a publishing company. Several coauthors have financial relationships with the pharmaceutical industry. Dr. Tyler, Dr. Shaw, and Dr. Feldman report no relevant financial relationship.

The downward trend of isothiazolinone allergy in Europe after its peak in 2013 and 2014 may have been due in part, the authors explain, to a memo released in 2013 by Cosmetics Europe after it and the European Society of Contact Dermatitis reviewed reports of increased contact allergy to MI. The memo urged companies to remove MI from leave-on products.

Later that year, the European Union’s Scientific Committee on Consumer Safety advised omitting MI from leave-on consumer personal care products and moved to restrict the ingredient in rinse-off products to less than 15 ppm. The recommendation took effect in 2015.

That year, Canada banned the use of MCI/MI in leave-on products but allowed MI alone in leave-on products until 2018. The total concentration of MI and MCI in wash-off products was limited to less than 15 ppm.

The authors add that, to their knowledge, the U.S. government does not restrict the use of MCI/MI or MI.
 

Policy implications for contact allergy

MI is still widely used in “countless products,” including shampoos, skin cleansers, dishwashing and laundry detergents, paints, and adhesives, Daniel W. Shaw, MD, associate professor of dermatology at the University of California, San Diego, told this news organization by email.

“Exact figures between the U.S. and Europe are difficult to compare due to differing patch test concentrations, but the overall trends strongly suggest that stricter and earlier regulation in Europe resulted in lower MI allergy prevalence there than in the U.S.,” added Dr. Shaw, who was not involved in the study.

Steven R. Feldman, MD, PhD, professor of dermatology at Wake Forest University in Winston-Salem, N.C., said by email that accurate information on allergic reaction prevalence is difficult to find.

“The NACDG, ESSCA, and IVDK databases may contain the best data available, but the data depend on people who get patch tested and are not directly informative of the allergy rates in the general population,” added Dr. Feldman, who was not involved in the study.

“The great majority of people in the population may not be allergic,” he said. “For those with itchy rashes, getting patch tested or avoiding products with preservatives may be prudent. Broad regulations, however, should consider the overall risks and benefits in the population, and this particular study does not fully capture those issues.”

“This study shows that government regulations are important to limit consumer exposure to common allergens, especially to the concentrations used in personal care products,” Kelly Tyler, MD, associate professor of dermatology at the Ohio State University Wexner Medical Center in Columbus, noted by email. She was not involved in the study.

She advised clinicians to ask their patients who may have allergic contact dermatitis whether they have been exposed to products containing these compounds.

“All personal care products in the store contain preservatives, and their maximum concentrations should be limited,” she advised. “The Expert Panel for Cosmetic Ingredient Safety should establish stricter guidelines for MI use in personal care products, especially given the findings of this study.”
 

Has MI contact allergy in North America peaked?

“In the U.S., MI has not been banned from leave-on skin-care products, but recently, its use has markedly decreased,” Dr. Shaw commented. “Hopefully, the prevalence of MI contact allergy will also begin to decrease.”

New evidence is promising. In a related study published online in Dermatology, Joel G. DeKoven, MD, MHSc, FRCPC, of the University of Toronto and his colleagues reported the NACDG 2019-2020 patch test results for MI in North America. They found that 13.8% of patients tested positive for MI.

“For the first time, MI positivity did not increase between reporting periods,” they conclude. “The epidemic of MI contact allergy in North America may have reached a plateau.”

Information regarding funding for the study was not provided. Dr. Reeder has financial relationships with the American Contact Dermatitis Society and a publishing company. Several coauthors have financial relationships with the pharmaceutical industry. Dr. Tyler, Dr. Shaw, and Dr. Feldman report no relevant financial relationship.

The prevalence of contact allergy triggered by a common product preservative, isothiazolinone, has decreased in Europe while it has increased in North America, a trend that is likely driven by regulatory differences, a retrospective cohort study suggests.

“Between 2009 to 2018, the global burden of isothiazolinone allergy showed divergent trends between North American and European countries,” lead study author Margo J. Reeder, MD, of the University of Wisconsin in Madison and her colleagues write. The study was published online in JAMA Dermatology.

Isothiazolinone contact allergy peaked in Europe in 2013-2014 before gradually decreasing, they found. The prevalence of isothiazolinone allergy steadily increased in North America during the study period. “Earlier and more stringent regulation of MI [methylisothiazolinone] in Europe is associated with these divergent trends,” they write.
 

Common ingredients worldwide

Isothiazolinone preservatives, which are added to personal and industrial products, cause allergic contact dermatitis worldwide, the authors write. The preservatives are found in a wide range of leave-on and rinse-off water-based personal care products, such as shampoo and other hair products, dishwashing liquid, face cream, body lotion, shower gel, liquid soap, and wet wipes, as well as in water-based paint.

A mixture of methylchloroisothiazolinone (MCI) and MI has been used to prevent microbial growth in products since the 1980s. In 2005, U.S. and European regulators approved MI alone at higher concentrations as a preservative in personal care products. Coupled with consumer concerns about other preservatives, such as parabens (a rare allergen), use of MI in personal care products increased, the authors write.

Subsequently, researchers reported a global increase in the prevalence of contact allergy to isothiazolinones, the authors write. Regulatory restrictions on MI in personal care products were implemented in 2013 in Europe and in 2015 in Canada but not in the United States.
 

Patch test data reveal latest trends

To compare prevalence trends of allergic contact allergy to MI and sensitization to the MCI/MI mixture in North America and in Europe, Dr. Reeder and her colleagues compared the prevalence of positive patch test reactions to MCI/MI and to MI alone in North America and in Europe between 2009 and 2018.

They analyzed data from the North American Contact Dermatitis Group (NACDG), the European Surveillance System on Contact Allergies (ESSCA), and the Information Network of Departments of Dermatology (IVDK) in 2-year intervals. The data came from patients who had been patch tested at referral patch test clinics in North America and Europe.

Over the decade, the study sites conducted patch testing for 226,161 patients for MCI/MI and 118,779 for MI. Most data came from Europe. The researchers found the following:

• In Europe, isothiazolinone allergy peaked in 2013 and 2014; MCI/MI positivity reached 7.6% (ESSCA) and 5.4% (IVDK) before decreasing to 4.4% (ESSCA) and 3.2% (IVDK) in 2017-2018.
• In North America, MCI/MI positivity rose steadily from 2.5% in 2009-2010 to 10.8% in 2017-2018.
• In Europe, there were 5.5% (ESSCA) and 3.4% (IVDK) positive reactions to MI, compared with 15% (NACDG) in North America in 2017-2018.

The patient was diagnosed with lichen nitidus, given the characteristic clinical presentation.

Lichen nitidus is a rare chronic inflammatory condition of the skin that most commonly presents in children and young adults and does not seem to be restricted to any sex or race. The classic lesions are described as asymptomatic to slightly pruritic, small (1 mm), skin-colored to hypopigmented flat-topped papules.

Koebner phenomenon is usually seen in which the skin lesions appear in areas of traumatized healthy skin. The extremities, abdomen, chest, and penis are common locations for the lesions to occur. Rarely, the oral mucosa or nails can be involved. It has been described in patients with a diagnosis of Crohn’s disease, Niemann-Pick disease, Down syndrome, and HIV. The rare, generalized purpuric variant has been reported in a few cases associated with interferon and ribavirin treatment for hepatitis C infection and nivolumab treatment for cancer. The pathophysiology of lichen nitidus is unknown.

Lichen nitidus can occur in the presence of other skin conditions like lichen planus, atopic dermatitis, vitiligo, erythema nodosum, and lichen spinulosus. Histopathologic characteristics of lichen nitidus are described as a “ball and claw” of epidermal rete around a lymphohistiocytic infiltrate. Parakeratosis overlying epidermal atrophy and focal basal liquefaction degeneration is also seen.

The differential diagnosis of lichen nitidus includes flat warts, which can present as clusters of small flat-topped papules that can show a pseudo-Koebner phenomenon (where the virus is seeded in traumatized skin). The morphological difference between the condition is that lichen nitidus lesions are usually monomorphic, compared with flat warts, which usually present with different sizes and shapes.

Patients with a history of allergic contact dermatitis may present with a generalized monomorphic eruption of skin-colored papules (known as ID reaction) that can sometimes be very similar to lichen nitidus. Allergic contact dermatitis tends to respond fairly quickly to topical or systemic corticosteroids, unlike lichen nitidus. There are a few reports that consider lichen nitidus to be a variant of lichen planus, although they have different histopathologic findings. Lichen planus lesions are described as polygonal, pruritic, purple to pink papules most commonly seen on the wrists, lower back, and ankles. Lichen planus can be seen in patients with hepatitis C and may also occur secondary to medication.

Milia are small keratin cysts on the skin that are commonly seen in babies as primary milia and can be seen in older children secondary to trauma (commonly on the eyelids) or medications. Given their size and monomorphic appearance, they can sometimes be confused with lichen nitidus.

Lichen nitidus is often asymptomatic and the lesions resolve within a few months to years. Topical corticosteroids can be helpful to alleviate the symptoms in patients who present with pruritus. In more persistent and generalized cases, phototherapy, systemic corticosteroids, acitretin, isotretinoin, or cyclosporine can be considered.

Pounding heart, sweating, insomnia. Surges of dopamine, norepinephrine, and adrenaline. All symptoms of a very common yet frustrating condition: Falling in love.

The prognosis is vague. A prescription pad and knowledge of biochemistry aren’t helpful when it comes to relationships.

Medical training can consume decades when others are exploring relationships and starting families. There are few recent data on this, but a 2012 longitudinal study of more than 20,000 physicians by the UK Medical Careers Research Group found that, by age 25, the rate of doctors who were in partnerships was far lower than in the general population.

But there is hope! By age 36, the number of doctors in long-term relationships had overtaken everyone else by more than 10% for women and 20% for men. The Medscape 2022 Physician Happiness & Lifestyle Report found that 83% were in committed relationships, and even better, happy ones. At least three-quarters of doctors in every specialty described their partnerships as “very good” or “good.”

How should a single medical student, resident, or attending physician find happiness ever after in 2023? Sometimes Mr./Ms. Right can be found in the anatomy lab or hospital, with sparks flying between students or colleagues. But for many in health care, along with millions of others looking for love, the solution is dating apps.
 

When ‘MD’ is a turnoff

Dr. M, a psychiatry resident in California who prefers not to give her name, hadn’t found a life partner during college, grad school, or medical school. When she passed her final Step 3 board exam, she decided it was time to take the plunge. She signed up for popular dating apps like Hinge, Bumble, and Coffee Meets Bagel, but her dates seemed to follow a disappointing pattern.

“I met lots of guys, but it was incredibly rare to find another physician,” said Dr. M. “I found myself always wanting to talk about my life as a resident. More often than not, the guys would give me this blank stare as I complained about being on call or spoke about spending 12 hours a day studying for a board exam, or even the process of The Match and how I ended up in California.”

Both of Dr. M’s parents are physicians, and she grew up watching how they supported each other through residency, exams, and exhausting schedules. A relationship with another physician, her parents told her, would give both partners the best chance to understand each other’s lives. The problem was how to find one.

That was when Dr. M saw an ad for a dating app with a cute medical name: DownToDate, a play on the clinical evidence resource UpToDate. “I thought it was a meme,” she said. “It was this doctors-only app. I remember thinking, ‘this has to be a joke,’ but then it was very real.”

She signed up and was required to provide a photo of her ID and her NPI number. Immediately, men began “requesting a consult,” the app’s form of “liking” her profile, and sending her “pages” (messages).

DownToDate was created by another physician, Robin Boyer, MD, MBA, a pediatrics resident in Loma Linda, Calif. The inspiration came in 2020 during the initial COVID crisis. Exhausted from long and often heartbreaking shifts, Dr. Boyer was grateful for her husband’s unwavering support. But many of her coresidents weren’t so lucky. The women in particular talked about their dating struggles, and there was a recurring theme. They didn’t feel confident putting “physician” on a dating site profile.

“If you’re male and you tell people you’re a doctor, it seems like it really attracts people,” Dr. Boyer said. “But if you’re female, it brings up a lot of stereotypes where you’re perceived as too intimidating either as the breadwinner, being more educated, or having a [demanding] career. It does make it more difficult.”

Dr. Boyer met her husband in high school, and she had never used a dating app. She convinced a coresident, Celestine Odigwe, MD, to pursue the idea as partners. They began researching the market within their network and heard from over a thousand interested physicians, both men and women, heterosexual and LGBTQ+. They even created fake accounts on other sites to gauge how easy it is to falsify a profile. From these insights, the app took shape. It launched in 2021 and currently has more than 5000 verified users.
 

Branches from the same tree

Around the same time that DownToDate began, Shivani Shah, DO, a pediatric neurology resident at Duke University, Durham, N.C., and her brother, Sagar Shah, an entrepreneur, had a similar idea.

At the time, Dr. Shah was a fourth-year medical student about to move from New Jersey to North Carolina. Friends who were internal medicine residents described the grueling reality of the early COVID pandemic.

“It was just horrible,” said Dr. Shah. “You were isolated from your family, your support system, everything. ... I think the pandemic really pushed us into realizing that this is a very important need, and sometimes it feels like community is lacking in the health care field.”

The sibling duo developed ForeverX, an app for health care workers to find meaningful and long-term romantic connections. It launched in 2021.

Concerned that the medical field was “siloed,” the Shahs chose to open the app to physicians, dentists, nurses, physical therapists, and other health care professionals. “Opening up the doors to more communication” between the health care branches was a priority.

To prevent catfishing, the app uses a twofold vetting system. Each user submits a photo of their driver’s license and a selfie that must match. There is also health care verification through an NPI number, nurse’s ID, or a manual process for those without either. None of the information is stored.

Through personal experience with dating apps, Dr. Shah hopes ForeverX can improve on some of their flaws, particularly the problem of matches being overly filtered by preferences. The “natural way” of meeting people is not filtered. And while most people have a dating checklist in mind, meeting someone face to face might send some of those prerequisites “out the window.”

“You can’t really put into words how you feel with someone ... the vibe,” Dr. Shah said. That is why her goal is to get people off the app and on an actual date IRL. “Something we’ve discussed internally is, how do we make this experience that’s virtual more human?”

She acknowledged that certain requirements, like a desire for children, might be crucial to some users. Many female doctors in their 30’s feel the “time crunch” of a ticking biological clock.
 

Optimize your date-ability

“I think people either love or hate dating apps, and I love them,” said Kevin Jubbal, MD. “I get to meet cool people and schedule dates from the comfort of my home.”

Dr. Jubbal, a former plastic surgery resident who left medicine to become an entrepreneur, is the founder of Med School Insiders, a tutoring and advising resource for premeds, medical students, and residents. His YouTube channel has more than 1.5 million subscribers, and he often receives questions about whether dating is feasible in medical school and how to balance a personal and academic/professional life.

Those who hate dating apps or receive few matches would do well to look inward instead of blaming the process, he said. It helps to view the experience as a learning tool that provides feedback very quickly.

“If you want to find a really amazing person, then you need to be what you want to find,” said Dr. Jubbal. “If you want to find someone who’s fit and intelligent and well read and well traveled, you need to be that. Otherwise, you’re probably not going to attract that person.”
 

An app designed to help single female MDs

Ifie Williams, MD, a psychiatrist in Washington, D.C., believes a wider dating pool is key – provided everyone understands the situation up front. When Dr. Williams started residency in 2014, she was “as single as can be.” She tried many dating apps, but they were extremely time consuming. Even when she set specific preferences, she found herself sifting through “matches” that didn’t fit her criteria.

“Dating nowadays has become almost like a second job,” said Dr. Williams. “Just the amount of time that people are having to spend on apps, swiping left and right and then meeting people. You think they’re interested and then you deal with all these games.”

By 2017, Dr. Williams had invented Miss Doctor, a dating app that would connect female physicians and other doctoral-level professionals with men or women on a similar achievement level.

By definition, these people would not be intimidated by ambitious, busy women. They would be heavily screened and vetted. And one other proviso: they would have to pay for “likes.”

Most dating apps charge a subscription fee. Users are allowed to “like” numerous profiles and perhaps not bother responding to many matches. By contrast, Miss Doctor accounts are free and include a limited number of “likes” to indicate interest. Beyond that, there’s a price.

“We wanted to find a way to make people a little more intentional with how they like people on the app, so they give a little more thought to it,” Dr. Williams said. “So, we monetize it and use that to change behavior.”

After an initial launch in 2017, the app had to take a back seat while Dr. Williams started her psychiatry practice and got married herself. She plans to relaunch it in spring 2023.

Male or female, there is general agreement that finding time to date as a young physician isn’t easy. While DownToDate has had “doctor meets doctor” success stories, many users are still searching for “the one.”

Dr. Boyer believes that career challenges are not a reason to give up. “There are so many single and available people out there,” she said. “And everyone’s deserving of love. Even if you only have an hour a week.”

She signed up and was required to provide a photo of her ID and her NPI number. Immediately, men began “requesting a consult,” the app’s form of “liking” her profile, and sending her “pages” (messages).

DownToDate was created by another physician, Robin Boyer, MD, MBA, a pediatrics resident in Loma Linda, Calif. The inspiration came in 2020 during the initial COVID crisis. Exhausted from long and often heartbreaking shifts, Dr. Boyer was grateful for her husband’s unwavering support. But many of her coresidents weren’t so lucky. The women in particular talked about their dating struggles, and there was a recurring theme. They didn’t feel confident putting “physician” on a dating site profile.

“If you’re male and you tell people you’re a doctor, it seems like it really attracts people,” Dr. Boyer said. “But if you’re female, it brings up a lot of stereotypes where you’re perceived as too intimidating either as the breadwinner, being more educated, or having a [demanding] career. It does make it more difficult.”

Dr. Boyer met her husband in high school, and she had never used a dating app. She convinced a coresident, Celestine Odigwe, MD, to pursue the idea as partners. They began researching the market within their network and heard from over a thousand interested physicians, both men and women, heterosexual and LGBTQ+. They even created fake accounts on other sites to gauge how easy it is to falsify a profile. From these insights, the app took shape. It launched in 2021 and currently has more than 5000 verified users.
 

Branches from the same tree

Around the same time that DownToDate began, Shivani Shah, DO, a pediatric neurology resident at Duke University, Durham, N.C., and her brother, Sagar Shah, an entrepreneur, had a similar idea.

At the time, Dr. Shah was a fourth-year medical student about to move from New Jersey to North Carolina. Friends who were internal medicine residents described the grueling reality of the early COVID pandemic.

“It was just horrible,” said Dr. Shah. “You were isolated from your family, your support system, everything. ... I think the pandemic really pushed us into realizing that this is a very important need, and sometimes it feels like community is lacking in the health care field.”

The sibling duo developed ForeverX, an app for health care workers to find meaningful and long-term romantic connections. It launched in 2021.

Concerned that the medical field was “siloed,” the Shahs chose to open the app to physicians, dentists, nurses, physical therapists, and other health care professionals. “Opening up the doors to more communication” between the health care branches was a priority.

To prevent catfishing, the app uses a twofold vetting system. Each user submits a photo of their driver’s license and a selfie that must match. There is also health care verification through an NPI number, nurse’s ID, or a manual process for those without either. None of the information is stored.

Through personal experience with dating apps, Dr. Shah hopes ForeverX can improve on some of their flaws, particularly the problem of matches being overly filtered by preferences. The “natural way” of meeting people is not filtered. And while most people have a dating checklist in mind, meeting someone face to face might send some of those prerequisites “out the window.”

“You can’t really put into words how you feel with someone ... the vibe,” Dr. Shah said. That is why her goal is to get people off the app and on an actual date IRL. “Something we’ve discussed internally is, how do we make this experience that’s virtual more human?”

She acknowledged that certain requirements, like a desire for children, might be crucial to some users. Many female doctors in their 30’s feel the “time crunch” of a ticking biological clock.
 

Optimize your date-ability

“I think people either love or hate dating apps, and I love them,” said Kevin Jubbal, MD. “I get to meet cool people and schedule dates from the comfort of my home.”

Dr. Jubbal, a former plastic surgery resident who left medicine to become an entrepreneur, is the founder of Med School Insiders, a tutoring and advising resource for premeds, medical students, and residents. His YouTube channel has more than 1.5 million subscribers, and he often receives questions about whether dating is feasible in medical school and how to balance a personal and academic/professional life.

Those who hate dating apps or receive few matches would do well to look inward instead of blaming the process, he said. It helps to view the experience as a learning tool that provides feedback very quickly.

“If you want to find a really amazing person, then you need to be what you want to find,” said Dr. Jubbal. “If you want to find someone who’s fit and intelligent and well read and well traveled, you need to be that. Otherwise, you’re probably not going to attract that person.”
 

An app designed to help single female MDs

Ifie Williams, MD, a psychiatrist in Washington, D.C., believes a wider dating pool is key – provided everyone understands the situation up front. When Dr. Williams started residency in 2014, she was “as single as can be.” She tried many dating apps, but they were extremely time consuming. Even when she set specific preferences, she found herself sifting through “matches” that didn’t fit her criteria.

“Dating nowadays has become almost like a second job,” said Dr. Williams. “Just the amount of time that people are having to spend on apps, swiping left and right and then meeting people. You think they’re interested and then you deal with all these games.”

By 2017, Dr. Williams had invented Miss Doctor, a dating app that would connect female physicians and other doctoral-level professionals with men or women on a similar achievement level.

By definition, these people would not be intimidated by ambitious, busy women. They would be heavily screened and vetted. And one other proviso: they would have to pay for “likes.”

Most dating apps charge a subscription fee. Users are allowed to “like” numerous profiles and perhaps not bother responding to many matches. By contrast, Miss Doctor accounts are free and include a limited number of “likes” to indicate interest. Beyond that, there’s a price.

“We wanted to find a way to make people a little more intentional with how they like people on the app, so they give a little more thought to it,” Dr. Williams said. “So, we monetize it and use that to change behavior.”

After an initial launch in 2017, the app had to take a back seat while Dr. Williams started her psychiatry practice and got married herself. She plans to relaunch it in spring 2023.

Male or female, there is general agreement that finding time to date as a young physician isn’t easy. While DownToDate has had “doctor meets doctor” success stories, many users are still searching for “the one.”

Dr. Boyer believes that career challenges are not a reason to give up. “There are so many single and available people out there,” she said. “And everyone’s deserving of love. Even if you only have an hour a week.”

Pounding heart, sweating, insomnia. Surges of dopamine, norepinephrine, and adrenaline. All symptoms of a very common yet frustrating condition: Falling in love.

The prognosis is vague. A prescription pad and knowledge of biochemistry aren’t helpful when it comes to relationships.

Medical training can consume decades when others are exploring relationships and starting families. There are few recent data on this, but a 2012 longitudinal study of more than 20,000 physicians by the UK Medical Careers Research Group found that, by age 25, the rate of doctors who were in partnerships was far lower than in the general population.

But there is hope! By age 36, the number of doctors in long-term relationships had overtaken everyone else by more than 10% for women and 20% for men. The Medscape 2022 Physician Happiness & Lifestyle Report found that 83% were in committed relationships, and even better, happy ones. At least three-quarters of doctors in every specialty described their partnerships as “very good” or “good.”

How should a single medical student, resident, or attending physician find happiness ever after in 2023? Sometimes Mr./Ms. Right can be found in the anatomy lab or hospital, with sparks flying between students or colleagues. But for many in health care, along with millions of others looking for love, the solution is dating apps.
 

When ‘MD’ is a turnoff

Dr. M, a psychiatry resident in California who prefers not to give her name, hadn’t found a life partner during college, grad school, or medical school. When she passed her final Step 3 board exam, she decided it was time to take the plunge. She signed up for popular dating apps like Hinge, Bumble, and Coffee Meets Bagel, but her dates seemed to follow a disappointing pattern.

“I met lots of guys, but it was incredibly rare to find another physician,” said Dr. M. “I found myself always wanting to talk about my life as a resident. More often than not, the guys would give me this blank stare as I complained about being on call or spoke about spending 12 hours a day studying for a board exam, or even the process of The Match and how I ended up in California.”

Both of Dr. M’s parents are physicians, and she grew up watching how they supported each other through residency, exams, and exhausting schedules. A relationship with another physician, her parents told her, would give both partners the best chance to understand each other’s lives. The problem was how to find one.

That was when Dr. M saw an ad for a dating app with a cute medical name: DownToDate, a play on the clinical evidence resource UpToDate. “I thought it was a meme,” she said. “It was this doctors-only app. I remember thinking, ‘this has to be a joke,’ but then it was very real.”

In December 2021, major changes took effect in the iPLEDGE program, the Food and Drug Administration–required safety program for managing the risks of isotretinoin’s teratogenicity and preventing exposure during pregnancy. Now, more modifications may be coming to the acne drug’s safety program.

The FDA has scheduled a joint meeting of the Drug Safety and Risk Management Advisory Committee and the Dermatologic and Ophthalmic Drugs Advisory Committee for March 28-29 to discuss proposed changes to the iPLEDGE risk evaluation and mitigation strategy (REMS) requirements. The aim, according to the FDA meeting announcement, is “to minimize burden on patients, pharmacies, and prescribers while maintaining safe use of isotretinoin oral capsules for patients.”

Ocskay Bence/Fotolia.com

Isotretinoin is marketed as Absorica, Absorica LD, Claravis, Amnesteem, Myorisan, and Zenatane. Its former brand name was Accutane.

Problems began to surface days after a new, gender-neutral approach to the risk mitigation program was launched on Dec. 13, 2021. That program had been approved earlier by the FDA.

However, the problems that were encountered were a result of glitches in changes in the platform that had been planned, and were not related to the gender-neutral changes. The iPLEDGE program had transitioned to the new platform, and the rollout was far from smooth. Dermatologists, pharmacists, patients, parents of patients, and others were frustrated and angry that they could not access the new platform and obtain the medication promptly. Reaching the help line to sort out problems was another exercise in frustration. Wait times while on hold were unbearably long, or problems were not resolved over the phone.

(The new gender-neutral approach, which advocates said was needed to preserve inclusiveness of their patients, including transgender patients, places potential patients into two categories: those who can become pregnant, and those who cannot. Previously, there were three categories into which patients were classified: females who have reproductive potential, females who do not have reproductive potential, and males.)

Before pharmacists can fill a prescription for isotretinoin, a medical provider must confirm a patient’s negative pregnancy test and inform a patient with reproductive potential of the risks of the medication.

In January 2022, to deal with the chaotic launch and subsequent problems, the FDA said it would continue to meet with the Isotretinoin Products Manufacturers Group (IPMG) to resolve the problems reported by clinicians, pharmacists, and patients.

The American Academy of Dermatology Association formed an iPLEDGE work group to address the issues and suggest solutions. It has made several requests of and suggestions for the IPMG, which manages the program, according to Andrea L. Zaenglein, MD, professor of dermatology and pediatrics at Penn State Hershey (Pa.) Medical Center, and a member of the work group.

“We are asking them to eliminate the monthly attestation for patients who can’t get pregnant and to review and modify restrictive and punitive waiting and lockout periods for all patients,” she told this news organization.

As of February 2023, most of the platform glitches had been smoothed out, Dr. Zaenglein said. Still, “improvements to the design of the website could improve the user interface,” she added.


The FDA has established a docket for the public to submit comments before the meeting. The docket number is FDA-2022-N-3071. The electronic filing system will accept comments until 11:59 p.m. Eastern time on March 27. Background material and a link to the live webcast of the panel meeting will be available to the public no later than 2 days before the meeting and will be posted on the FDA web page or at the time of the meeting.

The U.S. Food and Drug Administration today expanded the indication for Pfizer’s oral Janus kinase (JAK) inhibitor for atopic dermatitis (AD), abrocitinib (Cibinqo), to include adolescents aged 12 through 17 years.

Abrocitinib, taken once daily, previously was approved only for treating adults aged 18 and older.

It joins upadacitinib (Rinvoq), previously the only oral JAK inhibitor to be approved for use by adolescents aged 12 through 17 with refractory moderate to severe AD.

The indication has been expanded for teens whose disease is not adequately controlled with other systemic drugs, including biologics, or those for whom use of those drugs is not advised.

Prescribing information was updated to reflect data from JADE TEEN, a phase 3, randomized, placebo-controlled trial that supported the indication for adolescents. That trial evaluated both the 100-mg and 200-mg doses of abrocitinib in comparison with placebo in 285 adolescents aged 12-18 who had moderate to severe AD and who were also receiving background therapy with topical medications.

The most common toxicities that were reported in at least 1% of patients treated with abrocitinib for up to 16 weeks included nasopharyngitis, nausea, and headache.

Efficacy measures included improvements in itch, skin clearance, and disease severity using the Investigator Global Assessment (IGA), the Peak Pruritus Numerical Rating Scale (PP-NRS), and the Eczema Area and Severity Index (EASI), according to the Pfizer statement announcing the expanded approval.

Select JADE TEEN findings include the following:

• IGA response rate of 0 or 1 at week 12: 39% with abrocitinib 100 mg; 46% with abrocitinib 200 mg; and 24% with placebo.
• EASI-75 response rate at week 12: 64%, 71%, and 41%, respectively.
• Proportion of participants achieving PP-NRS with at least a 4-point decrease from baseline at week 2: 13%, 25%, and 8%, respectively.

Data included in the prescribing information now encompass five randomized, placebo-controlled clinical trials and a long-term extension study with more than 1,600 patients treated with abrocitinib, according to the statement from Pfizer.

In a 2021 story, when JADE TEEN trial results were presented, Lawrence Eichenfield, MD, professor of dermatology and pediatrics, University of California, San Diego, and Rady Children’s Hospital, San Diego, told this news organization that he welcomed oral JAKs as a weapon against atopic dermatitis.

He noted that moderate to severe AD can have a tremendous impact on adolescents. “Traditionally, we have treated it with intermittent topical corticosteroids, but this has left a significant percentage of patients without long-term disease control,” he said.

Abrocitinib is not recommended for use with other JAK inhibitors, biologic immunomodulators, or other immunosuppressants.

AD, one of the most common inflammatory skin diseases, affects approximately 5%-10% of adults in the United States and approximately 11% of children. About one in three adults and one in three children and adolescents aged 17 and younger with AD have moderate to severe disease.

JAK inhibition is thought to modulate multiple cytokines involved in AD, including interleukin (IL)–4, IL-13, IL-31, IL-22, and thymic stromal lymphopoietin.

Prescribing information includes a warning that use of abrocitinib should be avoided by patients with an active, serious infection, including localized infections. A boxed warning is included in the labels of JAK inhibitors regarding the risk of serious infections, mortality, major cardiovascular events, and thrombosis.

Treatment risks and benefits should be carefully considered for patients with chronic or recurrent infections or those who have lived in or traveled in areas of endemic tuberculosis or endemic mycoses, the information states.

He noted that moderate to severe AD can have a tremendous impact on adolescents. “Traditionally, we have treated it with intermittent topical corticosteroids, but this has left a significant percentage of patients without long-term disease control,” he said.

Abrocitinib is not recommended for use with other JAK inhibitors, biologic immunomodulators, or other immunosuppressants.

AD, one of the most common inflammatory skin diseases, affects approximately 5%-10% of adults in the United States and approximately 11% of children. About one in three adults and one in three children and adolescents aged 17 and younger with AD have moderate to severe disease.

JAK inhibition is thought to modulate multiple cytokines involved in AD, including interleukin (IL)–4, IL-13, IL-31, IL-22, and thymic stromal lymphopoietin.

Prescribing information includes a warning that use of abrocitinib should be avoided by patients with an active, serious infection, including localized infections. A boxed warning is included in the labels of JAK inhibitors regarding the risk of serious infections, mortality, major cardiovascular events, and thrombosis.

Treatment risks and benefits should be carefully considered for patients with chronic or recurrent infections or those who have lived in or traveled in areas of endemic tuberculosis or endemic mycoses, the information states.

The U.S. Food and Drug Administration today expanded the indication for Pfizer’s oral Janus kinase (JAK) inhibitor for atopic dermatitis (AD), abrocitinib (Cibinqo), to include adolescents aged 12 through 17 years.

Abrocitinib, taken once daily, previously was approved only for treating adults aged 18 and older.

It joins upadacitinib (Rinvoq), previously the only oral JAK inhibitor to be approved for use by adolescents aged 12 through 17 with refractory moderate to severe AD.

The indication has been expanded for teens whose disease is not adequately controlled with other systemic drugs, including biologics, or those for whom use of those drugs is not advised.

Prescribing information was updated to reflect data from JADE TEEN, a phase 3, randomized, placebo-controlled trial that supported the indication for adolescents. That trial evaluated both the 100-mg and 200-mg doses of abrocitinib in comparison with placebo in 285 adolescents aged 12-18 who had moderate to severe AD and who were also receiving background therapy with topical medications.

The most common toxicities that were reported in at least 1% of patients treated with abrocitinib for up to 16 weeks included nasopharyngitis, nausea, and headache.

Efficacy measures included improvements in itch, skin clearance, and disease severity using the Investigator Global Assessment (IGA), the Peak Pruritus Numerical Rating Scale (PP-NRS), and the Eczema Area and Severity Index (EASI), according to the Pfizer statement announcing the expanded approval.

Select JADE TEEN findings include the following:

• IGA response rate of 0 or 1 at week 12: 39% with abrocitinib 100 mg; 46% with abrocitinib 200 mg; and 24% with placebo.
• EASI-75 response rate at week 12: 64%, 71%, and 41%, respectively.
• Proportion of participants achieving PP-NRS with at least a 4-point decrease from baseline at week 2: 13%, 25%, and 8%, respectively.

Among pediatric patients with psoriasis who began treatment with ustekinumab, etanercept, or methotrexate, the rate of serious infections at 6 months was low, with an incidence ranging between 14.9 and 25.6 per 1,000 person-years.

Those are key findings from what is believed to be the largest cohort study of its kind to estimate the 6-month rate of infections among children with psoriasis who started treatment with ustekinumab, etanercept, or methotrexate.

“Clinical trials have demonstrated high efficacy of new immunomodulatory agents in treating children with psoriasis,” lead author Maria C. Schneeweiss, MD, of the division of pharmacoepidemiology in the departments of medicine and dermatology at Brigham and Women’s Hospital and Harvard Medical School, Boston, and colleagues wrote in the article, which was published online in JAMA Dermatology. “However, the risk of infections in clinical practice has not been fully characterized by comparing these medications against each other in pairwise comparisons.”

Drawing from two large U.S. insurance claims databases, the researchers identified 2,338 patients aged 17 years and younger who were receiving treatment with a topical medication for psoriasis and started new treatment with ustekinumab, etanercept, or methotrexate. They stratified their analysis by the time before pediatric labeling (2009-2015) and after pediatric approval (2016-2021), and their follow-up of patients started 1 day after initiating treatment and ended at 6 months.

Of the 2,338 patients, 1,368 (58%) were girls. From 2009 through 2021, 379 patients began treatment with ustekinumab, 779 patients began treatment with etanercept, and 1,180 patients began treatment with methotrexate. The propensity score–adjusted incidence rate of serious infection was 18.4 per 1,000 person-years (3 events) for those who used ustekinumab, 25.6 per 1,000 person-years (9 events) for those who used etanercept, and 14.9 per 1,000 person-years (8 events) for those who used methotrexate. The adjusted rate of outpatient infections was 254.9 per 1,000 person-years (39 events) for those who used ustekinumab, 435.7 per 1,000 person-years (139 events) for those who used etanercept, and 433.6 per 1,000 person-years (209 events) for those who used methotrexate. Meanwhile, the adjusted rate ratio of outpatient infections was 0.58 for ustekinumab vs. etanercept, 0.66 for ustekinumab vs. methotrexate, and 0.95 for etanercept vs. methotrexate. The researchers found that ratios were similar during the off-label use era and after pediatric labeling.

Anna L. Grossberg, MD, director of pediatric dermatology at the Johns Hopkins Children’s Center, Baltimore, who was asked to comment on the work, told this news organization that the data on outpatient infections in ustekinumab users “demonstrated that they may have a decreased risk of infection compared to pediatric psoriasis patients treated with methotrexate or the TNF-alpha inhibitor etanercept. This is previously unreported and reflects my personal experience with this medication in my own pediatric psoriasis patients.” She added the study’s overall findings lend further support to the safety of biologic medications and nonbiologic systemic immunomodulatory treatments for management of psoriasis. “This study will help guide pediatric dermatologists in counseling patients and their families about these risks [of infection], and in general providing reassurance that these risks appear to be quite low,” Dr. Grossberg said. “In particular, ustekinumab, a newer biologic medication that was recently FDA-approved for children 6 years and older for pediatric psoriasis, was not associated with higher infection rates than the other agents analyzed in this study, and in fact appears to carry a reduced risk compared to both etanercept and methotrexate.”

She noted certain limitations of the study, including its reliance on insurance claims data, “which can be limiting because information on possible confounding variables may not be known,” she said. “For example, the authors point out that environmental and behavioral risk factors for serious infection could not be evaluated or adjusted for, nor could the severity of the patients’ psoriasis. Additionally, this study only reported on outpatient infections that resulted in an antibiotic or other medications being prescribed and filled. It therefore may have missed children who presented with certain viral infections (examples could include the common cold and uncomplicated ear infections), which often will not require a prescription medication. Furthermore, it would fail to capture those who may have been seen for an infection but failed to fill the intended prescription.”

Dr. Schneeweiss reported receiving grants from AbbVie and UCB to Brigham and Women’s Hospital unrelated to the topic of this study and outside the submitted work. The study was supported by a grant from the National Institute of Arthritis and Musculoskeletal and Skin Diseases. Dr. Grossberg reported having no financial disclosures.
