What are the clinical implications of recent skin dysbiosis discoveries?
NEW ORLEANS – .
“There’s still a lot for us to learn,” Adam Friedman, MD, professor and chair of dermatology at George Washington University, Washington, said at the annual meeting of the American Academy of Dermatology. “Multiple factors contribute to the variability in the skin microbiota, including age, sex, environment, immune system, host genotype, lifestyle, and pathobiology. The question becomes, when do these factors or impacts on the microbiota become clinically significant?”
According to Dr. Friedman, there are 10 times more bacteria cells than human cells in the human body, “but it’s not a fight to the finish; it’s not us versus them,” he said. “Together, we are a super organism.” There are also more than 500 species of bacteria on human skin excluding viruses and fungi, and each person carries up to 5 pounds of bacteria, which is akin to finding a new organ in the body.
“What’s so unique is that we each have our own bacterial fingerprint,” he said. “Whoever is sitting next to you? Their microbiota makeup is different than yours.”
Beyond genetics and environment, activities that can contribute to alterations in skin flora or skin dysbiosis include topical application of steroids, antibiotics, retinoids, harsh soaps, chemical and physical exfoliants, and resurfacing techniques. “With anything we apply or do to the skin, we are literally changing the home of many microorganisms, for good or bad,” he said.
In the realm of atopic dermatitis (AD), Staphylococcus aureus has been implicated as an offender in the pathophysiology of the disease. “It’s not about one single species of Staphylococcus, though,” said Dr. Friedman, who also is director of translational research at George Washington University. “We’re finding out that, depending on the severity of disease, Staph. epidermis may be part of the problem as opposed to it just being about Staph. aureus. Furthermore, and more importantly, these changes in the microbiota, specifically a decrease in microbial diversity, has been shown to precede a disease flare, highlighting the central role of maintaining microbial diversity and by definition, supporting the living barrier in our management of AD.”
With this in mind, researchers in one study used high-throughput sequencing to evaluate the microbial communities associated with affected and unaffected skin of 49 patients with AD before and after emollient treatment. Following 84 days of emollient application, clinical symptoms of AD improved in 72% of the study population and Stenotrophomonas species were significantly more abundant among responders.
Prebiotics, probiotics
“Our treatments certainly can positively impact the microbiota, as we have seen even recently with some of our new targeted therapies, but we can also directly provide support,” he continued. Prebiotics, which he defined as supplements or foods that contain a nondigestible ingredient that selectively stimulates the growth and/or activity of indigenous bacteria, can be found in many over-the-counter moisturizers.
For example, colloidal oatmeal has been found to support the growth of S. epidermidis and enhance the production of lactic acid. “We really don’t know much about what these induced changes mean from a clinical perspective; that has yet to be elucidated,” Dr. Friedman said.
In light of the recent attention to the early application of moisturizers in infants at high risk of developing AD in an effort to prevent or limit AD, “maybe part of this has to do with applying something that’s nurturing an evolving microbiota,” Dr. Friedman noted. “It’s something to think about.”
Yet another area of study involves the use of probiotics, which Dr. Friedman defined as supplements or foods that contain viable microorganisms that alter the microflora of the host. In a first-of-its-kind trial, researchers evaluated the safety and efficacy of self-administered topical Roseomonas mucosa in 10 adults and 5 children with AD. No adverse events or treatment complications were observed, and the topical R. mucosa was associated with significant decreases in measures of disease severity, topical steroid requirement, and S. aureus burden
In a more recent randomized trial of 11 patients with AD, Richard L. Gallo, MD, PhD, chair of dermatology, University of California, San Diego, and colleagues found that application of a personalized topical cream formulated from coagulase-negative Staphylococcus with antimicrobial activity against S. aureus reduced colonization of S. aureus and improved disease severity.
And in another randomized, controlled trial, Italian researchers enrolled 80 adults with mild to severe AD to receive a placebo or a supplement that was a mixture of lactobacilli for 56 days. They found that adults in the treatment arm showed an improvement in skin smoothness, skin moisturization, self-perception, and a decrease in the SCORing Atopic Dermatitis (SCORAD) index as well as in levels of inflammatory markers associated with AD.
Dr. Friedman also discussed postbiotics, nonviable bacterial products or metabolic byproducts from probiotic microorganisms that have biologic activity in the host. In one trial, French researchers enrolled 75 people with AD who ranged in age from 6 to 70 years to receive a cream containing a 5% lysate of the nonpathogenic bacteria Vitreoscilla filiformis, or a vehicle cream for 30 days. They found that compared with the vehicle, V. filiformis lysate significantly decreased SCORAD levels and pruritus; active cream was shown to significantly decrease loss of sleep from day 0 to day 29.
Dr. Friedman characterized these novel approaches to AD as “an exciting area, one we need to pay attention to. But what I really want to know is, aside from these purposefully made and marketed products that have pre- and postprobiotics, is there a difference with some of the products we use already? My assumption is that there is, but we need to see that data.”
Dr. Friedman disclosed that he is a consultant and/or advisory board member for Medscape/SanovaWorks, Oakstone Institute, L’Oréal, La Roche Posay, Galderma, Aveeno, Ortho Dermatologic, Microcures, Pfizer, Novartis, Lilly, Hoth Therapeutics, Zylo Therapeutics, BMS, Vial, Janssen, Novocure, Dermavant, Regeneron/Sanofi, and Incyte.

Practicing ethical medicine ‘is a requirement,’ not a luxury, expert says
NEW ORLEANS – , but results from a national survey of dermatology residency program directors suggest that ethics training is not a priority.
Of the 139 dermatology residency program or associate program directors surveyed in 2022, only 43% responded. Of these, 55% said that their program had no ethics curriculum. Among programs with an ethics curriculum, 75% were implemented in the past 10 years, and the most common settings for teaching ethics were formal didactics (32%) and ad hoc during clinical encounters (28%). Reported barriers to implementing and/or maintaining an ethics curriculum included a lack of time (30%), lack of faculty with expertise (24%), and lack of useful resources (20%).
“Clearly, medical ethics is needed more to be part of our dermatology residency curriculum,” one of the study authors, Jane M. Grant-Kels, MD, professor of dermatology, pathology, and pediatrics, and founding chair of dermatology at the University of Connecticut, Farmington, said during a plenary lecture at the annual meeting of the American Academy of Dermatology. “Why? Because even though we’re physicians, and some of us have big egos, we are just human beings. We have all the faults and frailties of other humans. What we do as doctors often has unintended consequences that impact patients and society at large.”
Dr. Grant-Kels, one of the editors of the textbook “Dermatoethics”, said that, while she does not believe that physicians are intentionally unethical, “we stumble into bad behavior because we fool ourselves. We think that we are ethical. We think our colleagues are ethical, and we don’t view them with a clear, transparent eye. This is referred to as ethical fading or bounded ethicality.”
Similar to religion and good behavior, one can’t really teach someone to be ethical, she continued. “But you can teach people to think about ethics and to recognize an ethical dilemma when they’re in one,” she said. “Most articles that are available [pertain to] whether ethics can be taught or not, but there are very few resources available on how to actually teach ethics.”
That, she added, has been her goal for the last 2 decades: “How do I teach ethics without sounding like I’m more ethical than anybody else, and how do I make it relevant and fun? It’s a difficult challenge.”
Pillars of medical ethics
Dr. Grant-Kels defined ethics as a way of determining how individuals ought to act based on concepts of right and wrong. An ethical dilemma is when an individual faces two competing possibilities: either both justifiable or both unjustifiable, and you have to make a decision. The four pillars of medical ethics, she noted, are beneficence (the notion that the patient’s best interests come first); nonmaleficence (do no intentional harm); autonomy (the patient’s right to refuse or choose a treatment); and justice (fairness in how health care is distributed).
“Medical ethics are the moral principles by which physicians should conduct themselves,” she said. “There is normative ethics, which involves decisions about which moral norms or ethical arguments should we accept and why; and applied ethics, or applications of these norms to specific problems or cases. No ethics is better than bad ethics, and we can see that even in today’s world. The lack of ethics, or poor ethics, or the wrong ethics has terrible consequences.”
Ethics instruction
Dr. Grant-Kels provided a “top 10 list” of tips for incorporating ethics instruction into dermatology residency programs and clinical practices:
- Make room for ethics in your curriculum. “It’s not science, and it needs to be discussed and developed with faculty and residents,” she said.
- Focus on real situations that residents will experience. Discuss what you should do, what you might have done, and why.
- Share stories and be truthful. Include other faculty members, “because you need different perspectives,” she said.
- Go beyond what is right and wrong, and the rationale. “You have to talk about the impact, because decisions you make have unintended consequences for individual patients and for patient care in general,” Dr. Grant-Kels said.
- Practice, practice, practice. Make time for discussions involving ethics, “because it takes a lot of education to be able to identify ethical issues and process them,” she said. “The truth is, we can rationalize almost anything and convince ourselves that we made the right choice. That’s why we need to continue to practice good ethics.”
- Challenge the residents. “Decisions are not always straightforward,” she said. “Pressures push us and we start to justify small decisions and then bigger decisions. This is a very gray zone. What’s ethical for one person may not be ethical to another.”
- Encourage residents and colleagues to ask the right questions and give them confidence to make the right decisions. “We have to work in an environment of ethics,” Dr. Grant-Kels said. “Many of us are role models, and we are not always behaving the way we should be. As role models, we need to be aware of that.”
- Expose residents to a variety of issues. Ethics vary depending on the situation, the people involved, and the information presented.
- Ethics cannot just come up in an ethics class. “We need to foster a culture of ethics,” she said. “If things go wrong and unethical behavior is noted, it needs to be brought to the floor and discussed.”
- Discuss the misguided pursuit of happiness and ethical decision-making. In the opinion of Dr. Grant-Kels, people can behave badly when they’re pursuing something like a career advancement, a new house, or an expensive object like a car or a boat. “They think that if they get that job or get that promotion or if they buy that big house or they buy that sports car, they’re going to be really happy,” she said.
“That’s called impact bias, which causes focalism, where you focus on that one thing, like ‘I’m going to make a lot of money’ or ‘I’m going to buy that big house on the mountain.’ The truth is, buying that car doesn’t make you happy. Buying that big house doesn’t make you happy. We need to combat focalism with professionalism, which means conducting oneself with responsibility, integrity, accountability, and excellence. Practicing ethical medicine is not a luxury; it’s a requirement. We should all try for aspirational ethics.”

- Challenge the residents. “Decisions are not always straightforward,” she said. “Pressures push us and we start to justify small decisions and then bigger decisions. This is a very gray zone. What’s ethical for one person may not be ethical to another.”
- Encourage residents and colleagues to ask the right questions and give them confidence to make the right decisions. “We have to work in an environment of ethics,” Dr. Grant-Kels said. “Many of us are role models, and we are not always behaving the way we should be. As role models, we need to be aware of that.”
- Expose residents to a variety of issues. Ethics vary depending on the situation, the people involved, and the information presented.
- Ethics cannot just come up in an ethics class. “We need to foster a culture of ethics,” she said. “If things go wrong and unethical behavior is noted, it needs to be brought to the floor and discussed.”
- Discuss the misguided pursuit of happiness and ethical decision-making. In the opinion of Dr. Grant-Kels, people can behave badly when they’re pursuing something like a career advancement, a new house, or an expensive object like a car or a boat. “They think that if they get that job or get that promotion or if they buy that big house or they buy that sports car, they’re going to be really happy,” she said.
“That’s called impact bias, which causes focalism, where you focus on that one thing, like ‘I’m going to make a lot of money’ or ‘I’m going to buy that big house on the mountain.’ The truth is, buying that car doesn’t make you happy. Buying that big house doesn’t make you happy. We need to combat focalism with professionalism, which means conducting oneself with responsibility, integrity, accountability, and excellence. Practicing ethical medicine is not a luxury; it’s a requirement. We should all try for aspirational ethics.”

Expect increased demand for experienced dermatologic care of Asian skin
NEW ORLEANS – With the Asian population estimated to increase to 41 million by 2050 in the United States, expect the demand for experienced dermatologic care of patients with Asian skin to increase in the coming years, Hye Jin (Leah) Chung, MD, said at the annual meeting of the American Academy of Dermatology.
“Asians account for about 60% of the global population,” said Dr. Chung, assistant professor of dermatology at Harvard Medical School, and director of the Asian Skin Clinic at Beth Israel Deaconess Medical Center, Boston. Along with the estimate that Asians are expected to make up 25% of Canada’s population by 2036, “we will most likely encounter more Asian skin type patients in North America,” Dr. Chung said, noting that the Asian population “is very diverse, ranging from skin type 3 in Far East Asia to skin type 5 in India.”
During her presentation, she provided tips for treating hypertrophic scars and keloids in this patient population when intralesional corticosteroids fail. Typically, her first option is to combine an intralesional corticosteroid with 5-fluorouracil (5-FU), a pyrimidine analogue with antimetabolite activity. 5-FU “can cause cell apoptosis of endothelial cells and fibroblasts (which steroids cannot), cell cycle arrest, and TGF-beta [transforming growth factor beta]-induced COL1A2 transcription,” Dr. Chung said. The recommended ratio between 5-FU and steroids in the literature is variable, from a 9:1 ratio to a 1:1 ratio. “In my practice I do not inject more than 100 mg at a time,” she said. Several studies of this approach led by Asian investigators used weekly injections, “but that’s not practical in the U.S. I usually do monthly injections.”
A large systematic review and meta-analysis confirmed that the combination of intralesional triamcinolone acetonide and 5-FU achieved a better efficacy and fewer complications than triamcinolone alone for treating hypertrophic scars and keloids. Potential side effects from 5-FU injections include pain/pruritus, transient hyperpigmentation (especially in skin types 4-6), ulceration, teratogenicity, and transient alopecia.
A more recent meta-analysis comparing the efficacy of multiple drug injections for hypertrophic scars and keloids confirmed that the combination of triamcinolone and 5-FU was superior to bleomycin, verapamil, 5-FU alone, and triamcinolone alone. “And, there was no difference between 5-FU/steroid combination and botulinum toxin A,” Dr. Chung added. “Some parts of the world are using botulinum toxin with mixed results. Based on the amount of toxin required for keloids, this would be cost prohibitive in the U.S.”
Another approach to treating hypertrophic scars and keloids in Asian skin is laser-assisted drug delivery. “First, you can use a fractional ablative laser to create a hole in the epidermis and dermis,” Dr. Chung said. “Then you can apply the suspension topically to the holes. You can also use a steroid ointment or cream after laser treatment for drug delivery.”
Combining pulsed dye laser with steroid injections is another option. Pulsed dye lasers coagulate microvasculature within keloid tissue, “which can cause tissue hypoxia and can decrease growth factors or cytokines for fibrosis within the tissue,” Dr. Chung said. At the cellular level, pulsed dye laser alone can decrease connective tissue growth factor (CTGF), TGF-beta 1, proliferating cell nuclear antigen, and collagen III, and increases matrix metalloproteinase–13 (MMP-13), P53, ERK and p38 MAPK, apoptosis, blockade of AP-1 transcription, and cell cycle changes.
In 2004, plastic surgeons in Korea described a new approach for removing earlobe keloids, which they termed a “keloid fillet flap”. For the procedure, about 50% of the keloid margin is incised with a #15 scalpel blade. “Then you dissect the keloid from the surrounding tissue with a blade or curved scissors,” Dr. Chung said. “Next, you excise the keloid, so you have some dead space. After hemostasis you place the fillet flap to cover the wound. After you trim the redundant tissue, you can close it with epidermal sutures.”
In her clinical experience, she finds the fillet flap “very helpful for fast recovery” and it is associated with less pain. “Several studies have confirmed an excellent improvement of keloids, low recurrence rate, and rare side effects from a fillet flap and adjuvant intralesional corticosteroids. Occasionally, you may see flap necrosis but usually patients do well with topical antibiotics or petrolatum jelly.”
Dr. Chung also discussed her approach to treating papular scars in Asian patients. She described papular scars as underrecognized, anetoderma-like scars on the central face and trunk. “They comprise about 11% of all acne scars but up to 19% of patients with such scars may not recall a history of acne,” she said. Biopsies of papular scars reveal marked reduction or thinning of elastic fibers around hair follicles.
“Papular scars are difficult to treat,” she said. “If you have a conventional Er:YAG or CO2 laser, you can create tiny holes within the scars,” she said, referring to studies on these approaches. Another treatment option is needle-guided radiofrequency, she noted.

Limited treatment options exist for brittle nail syndrome
NEW ORLEANS – .
“The mainstay of treatment is irritant avoidance and moisturization,” Shari R. Lipner, MD, PhD, associate professor of clinical dermatology and director of the nail division at Weill Cornell Medicine, New York, said at the annual meeting of the American Academy of Dermatology. “This works well if patients are religious about doing it.”
Brittle nail syndrome affects about 20% of adults, she said, and is more common in females, particularly those older than age 50. Most cases are idiopathic, but some are secondary to dermatologic diseases including nail psoriasis and nail lichen planus, and systemic diseases such as hyperthyroidism and hypothyroidism. They are more common in patients in certain occupations such as carpentry. “The pathogenesis is poorly understood but is thought to be due to weakened intercellular keratinocyte bridges, decreased cholesterol sulphate in the nail plate, and reduced water content in the nail plate,” Dr. Lipner said.
Key clinical findings include onychoschizia (peeling of the nail plate), onychorrhexis (an increase in the longitudinal ridges and furrows, sometimes leading to splitting), and superficial granulation of keratin. Treatment involves general measures. “You want to treat the underlying cause and recommend that the patient avoid water and irritant exposure,” she said. Her general instructions for affected patients are to wear latex gloves for wet work and cotton gloves for dry work, avoid triclosan-based hand sanitizers, avoid nail cosmetics, minimize nail trauma, and foster moisturization.“It’s important to give these instructions verbally and in written form,” she said. “In our practice, we designed a QR code that links to our patient handout.”
According to Dr. Lipner, the promotion of vitamins and supplements such as biotin, vitamin D, amino acids, and chromium for treating brittle nail syndrome is rampant on the Internet and on social media, but no rigorously designed clinical trials have shown efficacy for any of them. “Very few people are deficient in biotin, except for those with inherited enzyme deficiencies,” and most people “can get all the biotin they need from a regular diet,” she said.
The initial rationale for using biotin for nails comes from the veterinary literature, she continued. In the 1940s, chickens with biotin deficiency developed fissures in their feet and parrot-like beaks. In the 1970s, pigs with biotin deficiency developed friable hooves, which was corrected with biotin supplementation. “By the 1980s it was standard practice to supplement the feet of pigs with biotin,” she said.
In a human trial from 1989, German researchers enrolled 71 patients with brittle nail syndrome who took oral biotin, 2.5 mg daily. Of the 45 patients evaluated, 41 (91%) showed improvement in firmness and hardness of the fingernails over the course of 5.5 months, but there was no good control group, Dr. Lipner said. In a follow-up study, the same German researchers used scanning electron microscopy to evaluate 22 patients with brittle nails who took oral biotin 2.5 mg daily and compared them with 10 patients with normal nails who did not take biotin. They found a 25% increase in nail plate thickness in the biotin group and onychoschizia resolved in 50% of patients who received biotin. “But again, there was no good control group,” Dr. Lipner said.
In a third study on the topic, researchers surveyed 46 patients who presented with onychorrhexis and/or onychoschizia on clinical exam and took 2.5 mg of biotin daily. Of the 35 survey respondents, 63% subjectively reported improvement in their nails at a mean of 2 months. “This is where we are today: There have been studies of only 80 patients that were done 25 years ago,” Dr. Lipner said. “That’s all of our evidence for biotin for the treatment of brittle nail syndrome.”
FDA warning about biotin
Additional cause for concern, she continued, is the safety communication issued by the FDA in 2017, stating that the use of biotin may interfere with certain lab tests such as thyroid tests and cardiac enzymes, in some cases leading to death. The safety communication was updated in 2019.
In 2018, Dr. Lipner and colleagues administered an anonymous survey to 447 patients at their clinic asking about their use of biotin supplements. Of the 447 patients, 34% reported current use of biotin. Among biotin users, 7% were aware of the FDA warning, 29% of respondents reported that it was recommended by either a primary care physician or a dermatologist, and 56% underwent laboratory testing while taking biotin. “It’s our duty to warn our patients about the evidence for biotin for treating brittle nails, and about this interference on laboratory tests,” Dr. Lipner said.
Other treatment options for brittle nail syndrome include two lacquers that are available by prescription. One contains hydroxypropyl chitosan, Equisetum arvense, and methylsulphonylmethane; the other contains 16% poly-ureaurethane, but has not been well studied. “These products can be very expensive if not covered by insurance,” Dr. Lipner said.
As an alternative, she recommends Nail Tek CITRA 2 Nail Strengthener, which is available for less than $10 from Walmart and other retailers.
Cyclosporine emulsion also has been studied for brittle nail syndrome, but results to date have been underwhelming. Dr. Lipner and colleagues are exploring the effect of platelet rich plasma for treating brittle nails on the premise that it will improve nail growth and promote healing, in a 16-week trial that has enrolled 10 patients and includes both a Physician Global Improvement Assessment (PGIA) and a Physician Global Assessment (PGA) score. “Our data is being analyzed by three independent nail experts, and we hope to report the findings next year,” she said.
Dr. Lipner reported having no disclosures relevant to her presentation.

NEW ORLEANS – , compared with those who received vehicle cream, results from a pivotal phase 3 trial showed.
“Chronic hand eczema is the most frequent chronic inflammatory disorder affecting the hands,” Robert Bissonnette, MD, a dermatologist who is founder and CEO of Innovaderm Research, said at the annual meeting of the American Academy of Dermatology, where the study was presented during a late-breaking research session. “It’s associated with pain, pruritus, and has a huge impact on quality of life,” and results with current topical treatments are often unsatisfactory, he noted.
Delgocitinib is an investigational topical pan-JAK inhibitor that inhibits activation of the JAK-STAT pathway and targets key mediators of chronic hand eczema. In a phase 2b dose-ranging trial, twice-daily treatment with delgocitinib cream demonstrated significantly greater efficacy, compared with the cream vehicle, and was well tolerated in adults with mild to severe chronic hand eczema.
For the phase 3 study, known as DELTA 1, researchers randomized 487 adults with moderate to severe chronic hand eczema to receive twice-daily applications of delgocitinib cream 20 mg/g or cream vehicle for 16 weeks. After week 16, patients had the option to enter a long-term extension trial, which is currently ongoing. DELTA 1 was limited to adults with a diagnosis of chronic hand eczema defined as hand eczema that had persisted for more than 3 months or had returned more than twice within the past 12 months; an Investigator’s Global Assessment for chronic hand eczema (IGA-CHE) score of 3 (moderate) or 4 (severe); a weekly average Hand Eczema Symptom Diary (HESD) itch score of 4 or more points, and a medical history of inadequate response to topical corticosteroids within the past 12 months or for whom treatment with topical corticosteroids was not medically advisable.
The IGA-CHE scale used in the trial was new, “where, in order to be almost clear, the only sign that could be present on the skin was barely perceptible erythema,” Dr. Bissonnette said. He noted that he has used many IGA scales over the more than 25 years he has been involved with clinical trials, and “this was the first that used a scale with a bar so high.” Key secondary endpoints include a 75% and 90% improvement in Hand Eczema Severity Index (HECSI) from baseline at week 16 and a 4-point or greater improvement in the Dermatology Life Quality Index (DLQI) from baseline at week 16.
The median age of patients was 44 years, 88% were White, 4% were Asian, 1% were Black, and the remainder were from other racial groups. One-third of patients (33%) had severe hand eczema based on their IGA-CHE score, the median HECSI was 65 (in line with severe disease), and the median DLQI was 12. As for previous chronic hand eczema treatments, 19% had undergone phototherapy, 14% had tried oral retinoids, and 12% had tried oral corticosteroids.
In the study, a greater proportion of delgocitinib-treated patients achieved the primary endpoint of IGA-CHE 0/1, compared with the cream vehicle group at week 4 (15.4% vs. 4.9%; P < .001); week 8 (22.8% vs. 10.5%; P = .001), and week 16 (19.7% vs. 9.9%; P = .006). “As early as week 2, there is a separation between cream and vehicle,” Dr. Bissonnette said. When reviewing the results and the patients in the trial, he said that, in his personal opinion, “I don’t think this is uniquely representative of the efficacy of the drug,” because of the IGA scale that was used, which set such a high bar for efficacy.
As for secondary endpoints, a greater proportion of delgocitinib-treated patients than those in the vehicle group achieved a HESCI-75 (49.2% vs. 23.5%), a HECSI-90 (29.5% vs. 12.3%), and a 4-point or greater improvement on the DLQI (74.4% vs 50%; P < .001 for all endpoints).
Delgocitinib had a similar safety profile as the vehicle over 16 weeks, with no difference between the delgocitinib and vehicle arms in the proportion of patients who had adverse events (45.2% vs. 50.6%, respectively) and serious adverse events (1.8% vs. 1.9%). The most common adverse events (defined as 5% or greater in any treatment group) during the study were COVID-19 infections and nasopharyngitis; rates were comparable in the two arms.
Raj Chovatiya, MD, PhD, a dermatologist who directs the Center for Eczema and Itch at Northwestern University, Chicago, who was asked to comment on the study, said that chronic hand eczema can be functionally limiting for many patients. “Given its focal symptoms but multifaceted immunopathogenesis, topical JAK inhibition represents a rational strategy for targeted treatment,” Dr. Chovatiya told this news organization. He was not an investigator in the trial.
“In the phase 3 DELTA 1 study, topical delgocitinib cream was superior to vehicle control with nearly one out of five patients achieving clear or almost clear skin, with no difference in total adverse events between groups. While both comparative and long-term data would be helpful to better assess how delgocitinib cream stacks up against common topical anti-inflammatories and how it may be used for a chronic condition that typically requires ongoing treatment, these findings move us closer to a potential first-in-class approved therapy for chronic hand eczema.”
Dr. Bissonnette disclosed that he served as a consultant and investigator for the developer of delgocitinib, LEO Pharma, on this study. He has also received grants and research funding from many other pharmaceutical companies. Dr. Chovatiya disclosed that he is a consultant to, a speaker for, and/or a member of the advisory board for several pharmaceutical companies, including LEO Pharma.

Pilot study evaluates sensitive skin burden in persons of color
NEW ORLEANS – .
Respondents also reported high rates of reactions to skin care products marketed for sensitive skin, and most said they had visited a dermatologist about their condition.
Those are among the key findings of a pilot study designed to assess the prevalence, symptom burden, and behaviors of self-identified persons of color with sensitive skin, which senior author Adam Friedman, MD, and colleagues defined as a subjective syndrome of cutaneous hyperreactivity to otherwise innocuous stimuli. “Improved understanding of sensitive skin is essential, and we encourage additional research into pathophysiology and creating a consensus definition for sensitive skin,” Dr. Friedman, professor and chair of dermatology at George Washington University, Washington, said in an interview in advance of the annual meeting of the American Academy of Dermatology, where the study was presented during an e-poster session. The findings were also reported online in JAAD International.
In May of 2022, Dr. Friedman, first author Erika McCormick, a 4th-year medical student at George Washington University, and colleagues invited individuals attending a community health fair in an undeserved area of Washington, to complete the Sensitive Scale-10 (SS-10) and to answer other questions after receiving a brief education about sensitive skin. Of the 58 respondents, 78% were female, and 86% self-identified as a person of color.
“Our study population predominantly self-identified as Black, which only represents one piece of those who would be characterized as persons of color,” Dr. Friedman said. “That said, improved representation of both our study population, and furthermore persons of color, in all aspects of dermatology research is crucial to at a minimum ensure generalizability of findings to the U.S. population, and research on sensitive skin is but one component of this.”
Nearly two-thirds of all respondents (63.8%) reported having an underlying skin condition, most commonly acne (21%), eczema (17%), and rosacea (6%). More than half (57%) reported sensitive skin, 27% of whom reported no other skin disease. Individuals with sensitive skin had higher mean SS-10 scores, compared with those with nonsensitive skin (14.61 vs. 4.32; P = .002) and burning was the main symptom among those with sensitive skin (56%), followed by itch (50%), redness (39%), dryness (39%) and pain (17%).
Compared with those who did not meet criteria for sensitive skin, those who did were more likely to report a personal history of allergy (56.25% vs. 8.33%; P = .0002) and were nearly seven times more likely to have seen a dermatologist about their concerns (odds ratio, 6.857; P = .0012).
In other findings limited to respondents with sensitive skin, 72% who reported reactions to general consumer skin care products also reported reacting to products marketed for sensitive skin, and 94% reported reactivity to at least one trigger, most commonly extreme temperatures (34%), stress (34%), sweat (33%), sun exposure (29%), and diet (28%). “We were particularly surprised by the high rates of reactivity to skin care products designed for and marketed to those suffering with sensitive skin,” Ms. McCormick told this news organization. “Importantly, there is currently no federal or legal standard regulating ingredients in products marketed for sensitive skin, and many products lack testing in sensitive skin specifically. Our data suggest an opportunity for improvement of sensitive skin care.”
She acknowledged certain limitations of the study, including its small sample size. “Reconducting this survey in a larger population will help validate our findings,” she said.
The research was supported by two independent research grants from Galderma: one supporting Ms. McCormick with a Sensitive Skin Research Fellowship and the other a Sensitive Skin Research Acceleration Fund. Dr. Friedman reported having no relevant disclosures.

Expert shares her tips for diagnosing, treating onychomycosis
NEW ORLEANS – .
“The PAS [periodic acid-Schiff] stain is very popular because it can identify the presence or absence of fungal elements, but a fungal culture will identify the organism living in the nail,” Dr. Elewski, professor and chair of dermatology at the University of Alabama, Birmingham, said at the annual meeting of the American Academy of Dermatology. “You also could do a PCR to identify the organism, with or without a KOH or PAS stain. It is often helpful to know what organism is causing the infection.”
While waiting for lab results, there are three clinical clues to look for – the first being that an infection likely resides in the toenail. “You almost never see dermatophyte onychomycosis in the fingernails without it being in the toenails, too,” Dr. Elewski said.
The presence of tinea pedis is a second clinical clue. “Sometimes it’s subtle, so I will ask the patient, ‘Have you been treating yourself for athlete’s foot?’ If they say ‘no, I’ve never had it,’ put down on your list that it’s unlikely they have onychomycosis. How is the fungus going to jump from the floor into the nail without taking a little vacation on the bottom of the foot? It just isn’t going to happen.”
The presence of dermatophytoma is the third clinical clue. “These are dermatophyte abscesses encased in a biofilm, and they’re really hard to treat,” she said.
Treatments
Clinicians typically turn to one of three oral drugs for treating onychomycosis: terbinafine, itraconazole, and fluconazole, Dr. Elewski noted. Referring to terbinafine as “the gold standard,” she said that she typically writes a prescription for 90 250-mg pills. “When I give terbinafine, I often do baseline liver profiling, depending on the patient’s age, their state of health, their comorbidities, and other medications they’re taking,” she said. “If they’re 18 years old and otherwise healthy, I probably don’t.” While she generally prescribes 90 pills, she added, “keep in mind that 90 pills are not going to cure everybody. I see the patient 4 months later because the drug should stay in the nail for 30 days or more at therapeutic levels after you take that 90-day course.”
Another option is itraconazole, which can be taken at a dose of 200 mg a day for 12 weeks, or at a pulse dose, where patients take 400 mg every day for 1 week, 1 week a month, for 4 consecutive months. “I’ll often do a baseline liver profile with itraconazole, too,” Dr. Elewski said. “I don’t think you have to, but it makes sense if it’s feasible for you. Decide that based on each patient.”
Itraconazole can’t be given concomitantly with statins because of the potential for rhabdomyolysis. For patients taking statins, she consults with their physicians to make sure it’s safe to stop the statin a couple of days before and after their scheduled pulse dose of itraconazole. “This involves 1 week per month of taking itraconazole without the statin,” she said. “Or they could stop statins for the time you treat, if cleared by their doctor.”
As for fluconazole, Dr. Elewski usually prescribes 200 mg once or twice per week until the nail is normal. She offers patients the mnemonic for “Fungal Fridays” or Toesdays” as a way for them to remember which day to take the fluconazole.
According to data in the package inserts, rates of complete and mycologic cures are 38% and 70% for terbinafine, respectively, 14% and 54% for itraconazole, and 37% to 48% and 47% to 62% for fluconazole. “These cures are not 100% based on the standard course [of the drug],” Dr. Elewski noted. “I don’t use the standard course. I believe in treating to terminate. You want to kill the fungus.”
Resistant dermatophytes ‘are coming’
Halting treatment with an oral drug at a particular time point instead of when the nail is fungal-free likely contributes to resistant strains, she added, noting that she has at least two dozen patients in her practice with dermatophyte resistance documented in labs. “We need to be antifungal stewards, because resistant dermatophytes are coming to us,” she said. “They’re here already, and we don’t want it to be endemic in the U.S.”
In a published study from 2020, researchers from India enrolled 200 patients with relapsing tinea corporis, tinea cruris, and tinea faciei and allocated 50 each to treatment with either fluconazole, griseofulvin, itraconazole, or terbinafine. At week 4, all treatment arms had cure rates of less than 8%. At week 8, the cure rates were 42% for fluconazole, 16% for griseofulvin, 28% for terbinafine, and 66% for itraconazole.
Based in part on these study findings, Dr. Elewski said that she has become more aggressive in her therapeutic approach, including treating some of her patients on terbinafine for a minimum of 6 months. “If that’s not enough, I keep treating,” she said. “But, patients may not respond to terbinafine; we see resistance. So, itraconazole may be our best drug going forward for treating onychomycosis. You just have to watch out for side effects of itraconazole, mainly drug-drug interactions.”

“The PAS [periodic acid-Schiff] stain is very popular because it can identify the presence or absence of fungal elements, but a fungal culture will identify the organism living in the nail,” Dr. Elewski, professor and chair of dermatology at the University of Alabama, Birmingham, said at the annual meeting of the American Academy of Dermatology. “You also could do a PCR to identify the organism, with or without a KOH or PAS stain. It is often helpful to know what organism is causing the infection.”
While waiting for lab results, there are three clinical clues to look for – the first being that an infection likely resides in the toenail. “You almost never see dermatophyte onychomycosis in the fingernails without it being in the toenails, too,” Dr. Elewski said.
The presence of tinea pedis is a second clinical clue. “Sometimes it’s subtle, so I will ask the patient, ‘Have you been treating yourself for athlete’s foot?’ If they say ‘no, I’ve never had it,’ put down on your list that it’s unlikely they have onychomycosis. How is the fungus going to jump from the floor into the nail without taking a little vacation on the bottom of the foot? It just isn’t going to happen.”
The presence of dermatophytoma is the third clinical clue. “These are dermatophyte abscesses encased in a biofilm, and they’re really hard to treat,” she said.
Treatments
Clinicians typically turn to one of three oral drugs for treating onychomycosis: terbinafine, itraconazole, and fluconazole, Dr. Elewski noted. Referring to terbinafine as “the gold standard,” she said that she typically writes a prescription for 90 250-mg pills. “When I give terbinafine, I often do baseline liver profiling, depending on the patient’s age, their state of health, their comorbidities, and other medications they’re taking,” she said. “If they’re 18 years old and otherwise healthy, I probably don’t.” While she generally prescribes 90 pills, she added, “keep in mind that 90 pills are not going to cure everybody. I see the patient 4 months later because the drug should stay in the nail for 30 days or more at therapeutic levels after you take that 90-day course.”
Another option is itraconazole, which can be taken at a dose of 200 mg a day for 12 weeks, or at a pulse dose, where patients take 400 mg every day for 1 week, 1 week a month, for 4 consecutive months. “I’ll often do a baseline liver profile with itraconazole, too,” Dr. Elewski said. “I don’t think you have to, but it makes sense if it’s feasible for you. Decide that based on each patient.”
Itraconazole can’t be given concomitantly with statins because of the potential for rhabdomyolysis. For patients taking statins, she consults with their physicians to make sure it’s safe to stop the statin a couple of days before and after their scheduled pulse dose of itraconazole. “This involves 1 week per month of taking itraconazole without the statin,” she said. “Or they could stop statins for the time you treat, if cleared by their doctor.”
As for fluconazole, Dr. Elewski usually prescribes 200 mg once or twice per week until the nail is normal. She offers patients the mnemonic for “Fungal Fridays” or Toesdays” as a way for them to remember which day to take the fluconazole.
According to data in the package inserts, rates of complete and mycologic cures are 38% and 70% for terbinafine, respectively, 14% and 54% for itraconazole, and 37% to 48% and 47% to 62% for fluconazole. “These cures are not 100% based on the standard course [of the drug],” Dr. Elewski noted. “I don’t use the standard course. I believe in treating to terminate. You want to kill the fungus.”
Resistant dermatophytes ‘are coming’
Halting treatment with an oral drug at a particular time point instead of when the nail is fungal-free likely contributes to resistant strains, she added, noting that she has at least two dozen patients in her practice with dermatophyte resistance documented in labs. “We need to be antifungal stewards, because resistant dermatophytes are coming to us,” she said. “They’re here already, and we don’t want it to be endemic in the U.S.”
In a published study from 2020, researchers from India enrolled 200 patients with relapsing tinea corporis, tinea cruris, and tinea faciei and allocated 50 each to treatment with either fluconazole, griseofulvin, itraconazole, or terbinafine. At week 4, all treatment arms had cure rates of less than 8%. At week 8, the cure rates were 42% for fluconazole, 16% for griseofulvin, 28% for terbinafine, and 66% for itraconazole.
Based in part on these study findings, Dr. Elewski said that she has become more aggressive in her therapeutic approach, including treating some of her patients on terbinafine for a minimum of 6 months. “If that’s not enough, I keep treating,” she said. “But, patients may not respond to terbinafine; we see resistance. So, itraconazole may be our best drug going forward for treating onychomycosis. You just have to watch out for side effects of itraconazole, mainly drug-drug interactions.”

Phase 3 prurigo nodularis trial shows positive results for nemolizumab
NEW ORLEANS – demonstrated.
Nemolizumab is a first-in-class investigational monoclonal antibody directed against the interleukin-31 receptor alpha that blocks signaling from IL-31. “From prior studies we know that it modulates pruritus, but also alters keratinocyte differentiation, inflammation, and fibrosis,” one of the investigators, Shawn G. Kwatra, MD, of the department of dermatology, Johns Hopkins University, Baltimore, said during a late-breaking research session at the annual meeting of the American Academy of Dermatology.
OLYMPIA 2 was a phase 3, multicenter, double-blind study in adults with PN presenting with 20 or more nodules, and Investigator’s Global Assessment (IGA) score of 3 or more, and the Peak Pruritus Numerical Rating Scale (PP-NRS) score of 7 or more. Exclusion criteria included chronic pruritus resulting from an active condition other than PN, such as neuropathic and psychogenic pruritus and active atopic dermatitis. In addition, the use of topical steroids, considered a rescue therapy, was not allowed in the trial, Dr. Kwatra said.
After an initial screening period, 274 patients at 73 sites in nine countries were randomized 2:1 either to the nemolizumab monotherapy or placebo. Following an initial 60-mg subcutaneous dose, patients received 30 mg or 60 mg (depending on their baseline weight) every 4 weeks for 16 weeks. The primary endpoint was the proportion of patients with a 4-point or greater improvement in the PP-NRS from baseline at week 16 and the proportion of patients with IGA success at week 16.
Selected key secondary endpoints included the proportion of patients with a 4 point or greater improvement from baseline in the PP-NRS at week 4, the Sleep Disturbance Numerical Rating Scale at week 4, and the SD-NRS at week 16. Safety endpoints included the incidence and severity of all adverse events.
Of the 274 patients randomized, 183 received nemolizumab and 91 received placebo. A total of 174 patients in the nemolizumab group completed the study, compared with 88 in the placebo group. The mean age of study participants was 53 years, 61% were women, 79% were White, 14% were Asian, and the rest were from other racial groups. More than half (57%) had IGA category 3 disease (moderate) and the remainder had IGA category 4 disease (severe); 63% had 20-100 lesions, and the remainder had more than 100. About one-third of study enrollees (32%) had a history of atopy.
Primary, secondary endpoint results
Dr. Kwatra reported that 56.3% of the patients in the nemolizumab group achieved a 4-point or greater improvement in the PP-NRS at week 16, compared with 20.9% of those in the placebo group (P < .0001), while 37.7% of those in the nemolizumab group achieved IGA success at week 16, compared with 11% of those in the placebo group (P < .0001).
As for secondary endpoints, 41% of patients in the nemolizumab group achieved a 4-point or greater improvement in PP-NRS at week 4, compared with 7.7% of those in the placebo group (P < .0001); and 37.2% of patients in the nemolizumab group achieved a 4-point or greater improvement in SD-NRS at week 4, compared with 9.9% of those in the placebo group (P < .0001). Almost 52% of patients in the nemolizumab group achieved a 4-point or greater improvement in SD-NRS at week 16, compared with 20.9% of those in the placebo group (P < .0001); and 9.8% of those in the nemolizumab group achieved IGA success at week 4, compared with 1.1% of those in the placebo group (P < .0074).
Adverse events
Treatment-emergent adverse events occurred in 61.2% of subjects in the nemolizumab group, compared with 52.7% of those in the placebo group. “There were no imbalances overall, [including] no injection-related reactions in either group,” Dr. Kwatra said. There was one case of newly diagnosed asthma in the placebo arm, and none in the treatment arm.
The researchers observed a slightly increased onset of atopic dermatitis in the treatment arm, compared with the placebo arm (5.5% vs. 0%). “Seven out of those 10 patients actually had a history of atopic dermatitis or high IgE [levels] and they were mostly managed with topical steroids without study drug discontinuation,” Dr. Kwatra added. Neurodermatitis, or worsening of PN, occurred in 3.8% of patients in the nemolizumab group, compared with 11% of those in the placebo group.
“The results of this study extend the efficacy and safety findings from the phase 2 study of nemolizumab in patients with PN,” Dr. Kwatra concluded. “I think they also help to usher in a new era of PN [treatment] in prime time.”
Kenneth B. Gordon, MD, who chairs the department of dermatology at the Medical College of Wisconsin, Milwaukee, and was asked to comment on the study, was impressed with nemolizumab’s propensity for blocking IL-31. “To be able to treat PN effectively by simply blocking the itch and not having a significant inflammatory function is really interesting,” he said in an interview at the meeting. If approved, nemolizumab “gives us another treatment option for a disease that is really debilitating. It’s very promising and we hope [the drug] will be available to us in the near future.”
Nemolizumab is being developed by Galderma. According to a press release from the company, nemolizumab was granted Breakthrough Therapy designation by the Food and Drug Administration in December 2019 for the treatment of pruritus associated with PN, a status that was reconfirmed in February 2023.
Dr. Kwatra disclosed that he is an advisory board member/consultant for Galderma, AbbVie, Amgen, Arcutis, ASLAN Pharmaceuticals, Cara Therapeutics, Castle Biosciences, Celldex, Incyte, Johnson and Johnson, Leo Pharma, Novartis, Pfizer, Regeneron, and Sanofi. Dr. Gordon disclosed that he is a consultant to, an investigator for, and/or a member of the advisory board for several pharmaceutical companies, but not Galderma.

Novel single-use patch shows promise for primary axillary hyperhidrosis
NEW ORLEANS – , results from a pivotal randomized trial showed.
“This is a new kind of device that is going to be a nice tool to have for treating patients who have hyperhidrosis of the axilla,” the study’s lead investigator, David M. Pariser, MD, who practices dermatology in Norfolk, Va., said during a late-breaking abstract session at the annual meeting of the American Academy of Dermatology.
In a study known as SAHARA, investigators at 11 sites evaluated the efficacy of the targeted alkali thermolysis (TAT) patch, a single-use disposable device. The patch consists of a thin sodium layer on an adhesive overlay. It’s applied to the dry axilla, and as the patient sweats during treatment, the sweat reacts with the sodium. According to Dr. Pariser, this interaction generates precisely targeted thermal energy that targets sweat glands, leading to a reduction in excessive sweat production for up to three months.
The researchers enrolled 110 individuals with Hyperhidrosis Disease Severity Scale (HDSS) scores of 3 or 4 and randomized them to either an active TAT or a sham patch for up to 3 minutes. Their mean age was about 33 years, and slightly more than half were women. “If significant discomfort or pain was noted, [the patch] treatment was halted; otherwise, it was left on for 3 minutes,” said Dr. Pariser, professor of dermatology at Eastern Virginia Medical School, Norfolk. “The treated area was thoroughly cleaned after treatment, and the TAT patch was deactivated. This process was repeated on the other axilla.”
The HDSS, Gravimetric Sweat Production (GSP), and quality of life assessments for bother and impact were measured through 12 weeks. The quality of life assessments were an exploratory endpoint and scored from 0 to 4, with 4 being extremely bothered or impacted and 0 not being bothered or impacted at all. The primary efficacy endpoint was the proportion of treated patients achieving a 1 or 2 on the HDSS at week 4, compared with sham treatment.
Secondary endpoints included the proportion of patients with an improvement of at least 2 grades from baseline to 4 weeks in HDSS by treatment group; mean improvement in the quality of life scale bother by treatment group; mean improvement in the quality of life scale impact by treatment group; and the proportion of subjects with at least 50% improvement in GSP from baseline to 4 weeks in the active patch group only.
Adverse events (AEs) were divided into 3 categories: AEs at the treatment site (or skin reactions within the treated part of the axilla); procedure-related AEs (those that are the result of treatment, but not in the treated part of the axilla), and non-axillary AEs.
Dr. Pariser reported that at 4 weeks, 63.6% of patients in the active patch group versus 44.2% of those in the sham group improved to an HDSS score of 1 or 2 (P = .0332) and that 43.2% of those in the active patch group versus 16.3% of those in the sham group (P = .0107) achieved a 2-point or greater HDSS improvement. In addition, 9.1% of those in the active patch group achieved a 3-point improvement on the HDSS, compared with none in the sham group. “That’s an amazing improvement; you’re basically going from moderate or severe to none,” he commented.
In other findings, 60.5% of patients in the active patch group showed at least a 50% reduction in GSP, compared with 32.6% of those in the sham group (P = .0102), with mean reductions of 57.3 mg/5min and 18.2 mg/5min, respectively (P = .0036). As for quality-of-life outcome scores, bother associated with hyperhidrosis was reduced by 1.52 points in active versus 0.61 in sham subjects (P = .0005), while impact was reduced by 1.44 in active versus 0.57 in sham subjects (P = .0004).
Adverse events
A total of 13 patients in the active patch group experienced AEs at the treatment site, including six with erythema; four with erosion; two with burning, itching or stinging; and one with underarm odor. “The two procedure-related AEs in the TAT-treated group were compensatory sweating and irritant contact dermatitis due to the adhesive,” said Dr. Pariser said.
Most adverse events resolved in fewer than 2 weeks, and all were mild to moderate. No serious adverse events occurred. Only five adverse events occurred in the sham group.
The TAT patch is currently undergoing review by the Food and Drug Administration, and according to Dr. Pariser, no other body sites have been treated with the device.
Adam Friedman, MD, professor and chair of dermatology at George Washington University, Washington, who was asked to comment on the study, characterized hyperhidrosis as “an exceedingly common medical condition that is commonly overlooked even though it has a tremendous burden on quality of life. I should know, as both someone who manages a large cohort of these patients but also as someone who suffers from it.”
Treatment options “have historically been limited, many of which are off-label and some which are difficult to access due to cost and/or duration/frequency of treatment,” added Dr. Friedman, who was not involved with the study. “The TAT patch offers a new, targeted, in-office, practical procedure-based approach to treat primary axillary hyperhidrosis. Innovation is certainly welcomed and needed, and I am curious to see how this technology is employed in practice once approved.”
The device is being developed by Candesant Biomedical. Dr. Pariser disclosed that he is a consultant or investigator for Bickel Biotechnology, Biofrontera AG, Bristol Myers Squibb, Celgene Corporation, Novartis Pharmaceuticals, Pfizer, Regeneron, and Sanofi.

NEW ORLEANS – , results from a pivotal randomized trial showed.
“This is a new kind of device that is going to be a nice tool to have for treating patients who have hyperhidrosis of the axilla,” the study’s lead investigator, David M. Pariser, MD, who practices dermatology in Norfolk, Va., said during a late-breaking abstract session at the annual meeting of the American Academy of Dermatology.
In a study known as SAHARA, investigators at 11 sites evaluated the efficacy of the targeted alkali thermolysis (TAT) patch, a single-use disposable device. The patch consists of a thin sodium layer on an adhesive overlay. It’s applied to the dry axilla, and as the patient sweats during treatment, the sweat reacts with the sodium. According to Dr. Pariser, this interaction generates precisely targeted thermal energy that targets sweat glands, leading to a reduction in excessive sweat production for up to three months.
The researchers enrolled 110 individuals with Hyperhidrosis Disease Severity Scale (HDSS) scores of 3 or 4 and randomized them to either an active TAT or a sham patch for up to 3 minutes. Their mean age was about 33 years, and slightly more than half were women. “If significant discomfort or pain was noted, [the patch] treatment was halted; otherwise, it was left on for 3 minutes,” said Dr. Pariser, professor of dermatology at Eastern Virginia Medical School, Norfolk. “The treated area was thoroughly cleaned after treatment, and the TAT patch was deactivated. This process was repeated on the other axilla.”
The HDSS, Gravimetric Sweat Production (GSP), and quality of life assessments for bother and impact were measured through 12 weeks. The quality of life assessments were an exploratory endpoint and scored from 0 to 4, with 4 being extremely bothered or impacted and 0 not being bothered or impacted at all. The primary efficacy endpoint was the proportion of treated patients achieving a 1 or 2 on the HDSS at week 4, compared with sham treatment.
Secondary endpoints included the proportion of patients with an improvement of at least 2 grades from baseline to 4 weeks in HDSS by treatment group; mean improvement in the quality of life scale bother by treatment group; mean improvement in the quality of life scale impact by treatment group; and the proportion of subjects with at least 50% improvement in GSP from baseline to 4 weeks in the active patch group only.
Adverse events (AEs) were divided into 3 categories: AEs at the treatment site (or skin reactions within the treated part of the axilla); procedure-related AEs (those that are the result of treatment, but not in the treated part of the axilla), and non-axillary AEs.
Dr. Pariser reported that at 4 weeks, 63.6% of patients in the active patch group versus 44.2% of those in the sham group improved to an HDSS score of 1 or 2 (P = .0332) and that 43.2% of those in the active patch group versus 16.3% of those in the sham group (P = .0107) achieved a 2-point or greater HDSS improvement. In addition, 9.1% of those in the active patch group achieved a 3-point improvement on the HDSS, compared with none in the sham group. “That’s an amazing improvement; you’re basically going from moderate or severe to none,” he commented.

CSU in children: Study identifies biomarkers associated with responses to different treatments
NEW ORLEANS – , results from a single-center prospective study showed.
“Given that the majority of CSU cases in adults are due to autoimmunity and there being very [few] studies on biomarkers for CSU in children, our study furthers our current understanding of the role of different biomarkers in treatment response,” lead study author Alex Nguyen, MsC, said in an interview at the annual meeting of the American Academy of Dermatology, where the study was presented during a poster session.
To identify biomarkers with treatment and disease resolution in children with CSU, Mr. Nguyen, a 4-year medical student at McGill University, Montreal, and colleagues prospectively recruited 109 children from the Montreal Children’s Hospital Allergy and Immunology Clinic who reported hives for at least 6 weeks from 2013 to 2022. They obtained levels of thyroid stimulating hormone (TSH), anti-thyroxine peroxidase (anti-TPO), total immunoglobulin E (IgE), CD63, tryptase, eosinophils, MPV, and platelets; the weekly urticaria activity score (UAS7) was recorded at study entry.
Levels of treatment included antihistamines at standard dose, four times the standard dose, omalizumab, and resolution of treatment. The researchers used univariate and multivariate logistic regressions to determine factors associated with different treatment levels and resolution.
Slightly more than half of the study participants (55%) were female, and their mean age was 9 years. Mr. Nguyen and colleagues observed that elevated MPV was associated with the four times increased dose of antihistamines treatment level (odds ratio = 1.052, 95% confidence interval = 1.004-1.103). Lower age was associated with disease resolution (OR = 0.982, 95% CI = 0.965-0.999).
After adjustment for age, sex, TSH, anti-TPO, total IgE, CD63, eosinophils, MPV, and platelets, elevated tryptase was associated with the antihistamine use at standard dose level (OR = 1.152, 95% CI = 1.019-1.302) and lower tryptase levels with disease resolution (OR = .861, 95% CI = 0.777-0.955).
“We were fascinated when we found that tryptase levels in patients with chronic spontaneous urticaria were associated with standard dose of antihistamines and even disease resolution,” Mr. Nguyen said. “Higher tryptase levels were associated with standard dose antihistamines, which potentially could imply an increase in mast cell activation. Furthermore, we saw that lower tryptase levels were associated with disease resolution likely given if the disease may not have been as severe.”
He acknowledged certain limitations of the study, including a limited sample size and an unbalanced sample size among treatment groups. In the future, he and his colleagues plan to increase the sample size and to include other biomarkers such as interleukin (IL)-6, D-dimer, vitamin D, and matrix mettaloproteinase-9.
“Much as the name suggests, CSU often arises without a clear trigger,” said Raj Chovatiya, MD, PhD, assistant professor in the department of dermatology at Northwestern University, Chicago, who was asked to comment on the study. “Particularly in children, little is known about potential biomarkers that may guide treatment or disease resolution. While a larger, prospective analysis would better characterize temporal trends in serum biomarkers in relation to disease activity, these data suggest that underlying mechanisms of tryptase may be worth an in-depth look in children with CSU.”
The study was recognized as the second-best poster at the meeting. The researchers reported having no financial disclosures. The other study coauthors were Michelle Le MD, Sofianne Gabrielli MSc, Elena Netchiporouk, MD, MSc, and Moshe Ben-Shoshan, MD, MSc. Dr. Chovatiya disclosed that he is a consultant to, a speaker for, and/or a member of the advisory board for several pharmaceutical companies.
