AUSTIN, TEX. – Topical calcineurin inhibitors (TCIs) are an effective therapeutic option for pediatric patients with periorificial dermatitis (POD), as monotherapy or as part of a combination regimen, results from a retrospective cohort study showed.

The mainstays of treatment for POD include topical and oral antibiotics. In an interview prior to the annual meeting of the Society for Pediatric Dermatology, Ayelet Ollech, MD, said that the most common systemic agents used include erythromycin, azithromycin, and, in patients older than 8-10 years of age, minocycline or doxycycline. Topical agents, which are often used as monotherapy in mild disease, include metronidazole, clindamycin, erythromycin, sodium sulfacetamide, and, less often, azelaic acid, topical retinoids, and ivermectin. “TCIs (pimecrolimus 1% cream and tacrolimus 0.03% or 0.1% ointment) are a good steroid sparing option for POD,” said Dr. Ollech, a pediatric dermatology fellow at Ann & Robert H. Lurie Children’s Hospital of Chicago. “In the adult population, two randomized controlled studies of pimecrolimus 1% cream showed good results. In the pediatric population, there are only a few case series and case reports of TCIs for the treatment of POD.”

In what is believed to be the largest study of its kind, Dr. Ollech, Anthony J. Mancini, MD, and colleagues assessed the clinical utility of TCI in 132 pediatric patients with POD who were treated in the division of dermatology at Children’s Hospital of Chicago between 2008 and 2018. The researchers made note of epidemiologic variables, personal and family medical histories, possible triggers, duration of illness, previous treatments, distribution (periocular, perinasal, perioral, extra facial regions), severity of POD, treatment(s) prescribed, duration of therapy, clinical response, recurrences, and side effects. In an effort to capture missing data, the researchers performed follow-up via telephone for all patients who lacked appropriate follow-up documentation in the medical record.

Of the 132 patients, the female: male ratio was 1.2:1 and the median age at diagnosis was 4.2 years. About one-third of patients (33%) had involvement of one region, 38% had involvement of two regions, 26% had involvement of three regions, and 3% patients had involvement of all regions. The most common disorders on medical history were atopic dermatitis and asthma (in 29% and 17% of patients, respectively).


Dr. Ollech reported that 72 of the 132 patients (55%) had evaluable follow up data via either medical record documentation or the phone questionnaire. Of these, 67% were treated with TCI alone, 19% were treated with a combination of TCI and topical metronidazole, and 10% were treated with a combination of TCI and a systemic antibiotic. The median duration of treatment was 60 days. The researchers observed complete response in 65% of patients treated with TCI alone, in 64% of those treated with TCI and metronidazole, and in 70% of those treated with TCI and a systemic antibiotic. Adverse events attributed to TCI were rare and mild in severity.

“We were surprised that there were almost no reported side effects from the usage of TCIs as it is known that these agents can cause a burning or stinging sensation,” Dr. Ollech said. “Only one case described this side effect. We found 30% of the patients to have associated atopic dermatitis (AD) as well as a few patients with irritant dermatitis. We were also surprised how convenient the TCI treatment was for a patient who had POD and concomitant facial AD or even irritant dermatitis as an agent that can treat both. This can be very helpful for the parents that apply the medication to have a single solution to more than one rash.”

The researchers noted recurrence of POD in 14% of patients overall, including 6% of patients treated with TCI alone, 29% of patients treated with TCI and metronidazole, and 30% of patients treated with TCI and a systemic antibiotic.

Dr. Ollech acknowledged certain limitations of the study, including its retrospective design and lack of a control group. She and her colleagues reported having no financial disclosures.

Patients with atopic dermatitis (AD) should regularly be asked about conjunctivitis and referred to an ophthalmologist for diagnosis and therapy, if they develop conjunctivitis, according to a recent position statement from the International Eczema Council.

Patients with AD who develop conjunctivitis during dupilumab treatment may experience “bilateral inflammation of the anterior conjunctiva and hyperaemia of the limbus, which may cause nodular swelling.”according to the statement, which pertains to conjunctivitis in AD patients, “with and without dupilumab therapy.” (J Eur Acad Dermatol Venereol. 2019 May 6. doi: 10.1111/jdv.15608). Currently, there are no predictive factors of conjunctivitis and no guidance in the literature on how to manage conjunctivitis associated with dupilumab, which in some cases can make it necessary to stop treatment, the authors wrote.

The International Eczema Council (IEC) polled 86 dermatologists in 22 countries who are experts in AD; 46 members responded from 19 countries, including dermatologists from Australia, Canada, Denmark, France, Germany, Japan, Korea, the Netherlands, the United Kingdom, and the United States. The questions centered on the diagnosis and management of conjunctivitis in AD patients, and whether to refer cases to an ophthalmologist. Consensus was achieved if less than 30% of participants disagreed with a statement. IEC members then met in person at a European Academy of Dermatology and Venereology meeting in Paris to discuss the results of the survey. Survey respondents noted they had seen dupilumab-associated conjunctivitis in both pediatric and adult patients.

The IEC members recommended that:

• Patients should be informed about the risks of conjunctivitis before being prescribed dupilumab.
• AD patients should be asked “routinely” about ocular complaints or symptoms.
• AD patients with conjunctivitis should be referred to an ophthalmologist for diagnosis and treatment.
• AD patients with new-onset conjunctivitis during dupilumab treatment always should be referred to an ophthalmologist, especially in more severe cases such as when they do not respond to treatment with antihistamine or artificial tears.
• Dermatologists also should rule out keratoconjunctivitis before treating with dupilumab, as it may cause keratitis and blindness.
• Patients who have had keratoconjunctivitis in the past should not be precluded from treatment with dupilumab, and those who develop conjunctivitis during treatment should be referred to an ophthalmologist – but should stay on treatment while waiting for the consult.

“It was stressed that at this moment there are also no reliable data on the course of atopic keratoconjunctivitis and vernal keratoconjunctivitis during dupilumab treatment,” according to Jacob P. Thyssen, MD, PhD, Herlev and Gentofte Hospital, Hellerup, Denmark, and coauthors. These patients “should be carefully monitored by an ophthalmologist before and during treatment with dupilumab.”

The recommendations also centered around which treatments should be initiated by dermatologists, and which should be referred to ophthalmologists. Those patients with conjunctivitis should receive eye drops, eye ointment, or oral antihistamines from their dermatologists before an ophthalmology referral, the IEC members said. Dermatologists also should perform, or refer patients for, skin prick testing or specific IgE testing for aeroallergens in patients with AD who have conjunctivitis, and patch testing with an “ophthalmologic series, and native eye drops/ointments to diagnose possible delayed type hypersensitivity reactions to topical ingredients,” they added.

Among the treatments for conjunctivitis best left to ophthalmologists are cyclosporine, tacrolimus, or corticosteroid eye drops.

“Despite the more limited experience with eye drops by dermatologists, rapid access to ophthalmological service may be difficult, sometimes warranting a short course of corticosteroid eye drops without ophthalmological consultations,” Dr. Thyssen and associates said. “However, persistent or recurrent conjunctivitis requiring repeated or prolonged use of corticosteroid, tacrolimus, and ciclosporin-containing eye drops, must be managed by an ophthalmologist, given the risk of glaucoma, cataract, and infections.”

“The AD severity, conjunctivitis severity, possible contraindications, possible effect of dupilumab therapy on concomitant asthma or other comorbidities, as well as other treatment options, should be considered on an individual patient basis,” the authors concluded.

The IEC survey was limited by the small survey response and reliance on expert opinion.

The authors reported personal and institutional relationships in the form of grants, corporate sponsorships, advisory board memberships, investigator appointments, speakers bureau positions, and consultancies for a variety of pharmaceutical companies, agencies, societies, and other organizations. No funding was obtained for the study.

AUSTIN, TEX. – The majority of skin-related pediatric inpatient admissions in the United States involve treatment for cellulitis, results from a large study of national data showed.

“Skin conditions significantly affect pediatric inpatients, and dermatologists ought be accessible for consultation to enhance care and costs,” the study’s first author, Marcus L. Elias, said in an interview prior to the annual meeting of the Society for Pediatric Dermatology.

According to Mr. Elias, who is a 4th-year medical student at Rutgers New Jersey Medical School–Newark, few national studies on skin diseases for pediatric inpatients have been published in the medical literature. Earlier this year, researchers examined inpatient dermatologic conditions in patients aged 18 years and older (J Am Acad Dermatol 2019;80[2]:425-32), but Mr. Elias and associates set out to analyze the burden of inpatient pediatric dermatologic conditions on a national basis. “We wanted to see if the same conditions that were hospitalizing adults were also hospitalizing kids,” he said. “We found that this was indeed the case.”

The researchers queried the National Inpatient Sample database for all cases involving patients aged 18 years and younger during 2001-2013. The search yielded a sample of 16,837,857 patients. From this, the researchers analyzed diagnosis-related groups for dermatologic conditions denoting the principal diagnosis at discharge, which left a final sample of 84,090 patients. Frequency and chi-squared tests were used to analyze categorical variables.

More than half of patients (54%) were male, 36% were white, 48% had Medicaid insurance, and 43% had private insurance. Mr. Elias reported that the median length of stay for patients was 2 days and the median cost of care was $6,289.50 for each case. More than three-quarters of pediatric inpatients with dermatologic diagnoses were treated for “cellulitis” (66,147 cases, or 79%), with most cases involving the legs (16,875 cases, or 20%). Other pediatric inpatients were admitted for “minor skin disorder without complications” (5,458 cases, or 7%), and “minor skin disorder with complications” (2,822 cases, or 3%). A total of 64 patients died during the study period. Of these, 31 cases (50%) involved “skin graft and/or debridement of skin ulcer or cellulitis without complications,” the study found.

“We were surprised that the major cause of mortality for our patients was classified as ‘skin graft and/or debridement of skin ulcer or cellulitis without complications,’ as a similar diagnosis-related groupings exist denoting that complications did arise,” Mr. Elias said. “Still, it is not possible for us to determine if the mortality was from the skin graft/debridement or another cause entirely. It is possible that the procedure was without complications, only to have the patient succumb to an ancillary process.”

He acknowledged certain limitations of the study, including the fact that the function of dermatologic consults for hospitalized patients was not examined. “We also cannot draw conclusions as to whether improved outpatient therapy reduces the need for hospitalization,” he said. Mr. Elias reported having no financial disclosures.

More than three-quarters of pediatric inpatients with dermatologic diagnoses were treated for “cellulitis” (66,147 cases, or 79%), with most cases involving the legs (16,875 cases, or 20%). Other pediatric inpatients were admitted for “minor skin disorder without complications” (5,458 cases, or 7%), and “minor skin disorder with complications” (2,822 cases, or 3%). A total of 64 patients died during the study period. Of these, 31 cases (50%) involved “skin graft and/or debridement of skin ulcer or cellulitis without complications,” the study found.

“We were surprised that the major cause of mortality for our patients was classified as ‘skin graft and/or debridement of skin ulcer or cellulitis without complications,’ as a similar diagnosis-related groupings exist denoting that complications did arise,” Mr. Elias said. “Still, it is not possible for us to determine if the mortality was from the skin graft/debridement or another cause entirely. It is possible that the procedure was without complications, only to have the patient succumb to an ancillary process.”

He acknowledged certain limitations of the study, including the fact that the function of dermatologic consults for hospitalized patients was not examined. “We also cannot draw conclusions as to whether improved outpatient therapy reduces the need for hospitalization,” he said. Mr. Elias reported having no financial disclosures.

AUSTIN – The duration of neonatal intensive care unit (NICU) exposure decreases the risk of atopic dermatitis (AD), results from a large single-center study demonstrated.

“While more time in the NICU is associated with a lesser risk of developing atopic dermatitis, we certainly do not want to keep infants in the NICU longer in order to lower their risk of atopic dermatitis,” the study’s first author, Jennifer J. Schoch, MD, said in an interview prior to the annual meeting of the Society for Pediatric Dermatology. “Instead, we need to work on understanding the mechanisms behind this relationship. For example, are there certain exposures in the NICU that influence the cutaneous immunity to ultimately reduce the risk of atopic dermatitis?”

According to Dr. Schoch, a pediatric dermatologist at the University of Florida, Gainesville, the medical literature has been conflicted regarding the relationship between prematurity and eczema. A recent meta-analysis of 18 studies found an association between very preterm birth and a decreased risk of eczema, yet the risk became insignificant among children born moderately preterm (J Am Acad Dermatol. 2018;78[6]:1142-8). However, the factors contributing to this relationship are not well understood.

In an effort to explore the infant, maternal, and environmental factors of infants who developed AD, compared with infants who did not, Dr. Schoch and colleagues evaluated infants who were born at University of Florida Health from June 1, 2011, to April 30, 2017; had at least two well-child visits; and had at least one visit at 300 days old or later. The researchers included 4,016 mother-infant dyads in the study. Atopic dermatitis was diagnosed in 26.5% of the infants. Factors significantly associated with the incidence of AD were delivery mode (P = .0127), NICU stay (P = .0001), gestational age (P = .0006), and birth weight (P = .0020). Specifically, infants had a higher risk of developing AD if they were delivered vaginally, did not stay in the NICU, had a higher gestational age, or had a higher birth weight. Extremely preterm (less than 28 weeks’ gestation) and very preterm (28 to less than 32 weeks’ gestation) infants had the lowest rates of AD, at 10.9% and 19%, respectively.

When the researchers adjusted for other variables to their model, only length of stay in the NICU was related to the development of AD. Specifically, infants who spent more time in the NICU had a lower risk of developing atopic dermatitis (P = .0039).

“We were surprised to find that the length of stay in the neonatal intensive care unit was the strongest protective factor against the future development of eczema,” Dr. Schoch said. “Instead of this relationship being mediated by gestational age or birth weight, it was how much time the infants spent in the NICU that seemed to ‘protect’ from future eczema.”

She acknowledged certain limitations of the study, including its retrospective design with data gathered from electronic medical records. Also, “diagnosis was determined by ICD-9 or ICD-10 code, and not confirmed by dermatologists,” she said.

In their abstract, the researchers wrote that the finding highlights “the importance of early life interactions between the microbiome, developing cutaneous immunity, and the evolving skin barrier of the preterm infant. The skin microbiome of premature infants differs from full-term infants, in that the premature infant cutaneous microbiome is dominated by Staphylococcus species” (Microbiome. 2018;6[1]:98). They added that “the early presence of Staphylococcus on the skin may confer protection.”

Although the FP had never seen anything like this before, he was aware that dyes in tattoos could cause an allergic reaction. His research also suggested that sarcoidosis could occur in a tattoo, so this was part of his differential diagnosis written on the pathology form. He suggested a 4 mm punch biopsy to determine what was going on.

(See the Watch & Learn video on “Punch biopsy.”)

The pathology came back consistent with sarcoidosis. On the follow-up visit, the FP explained the diagnosis and suggested that the patient have a chest x-ray. The chest x-ray showed bilateral hilar adenopathy consistent with stage I sarcoidosis. The FP prescribed a 15-g tube of 0.05% clobetasol to treat the lesion and referred the patient to Dermatology and Pulmonology.

When the patient visited Dermatology 2 months later, most of the sarcoid plaques were flat but some remained raised and pruritic. The dermatologist offered intralesional triamcinolone for the stubborn plaques, and the patient consented. This intralesional steroid in conjunction with the topical steroid provided a good result that treated the itching and flattened the lesions. The remaining tattoo and color of the skin were not normal, but the patient was happy with the result. She had no pulmonary symptoms, and her pulmonary function tests showed a mild decrease in her diffusing capacity. She continued to see the dermatologist and pulmonologist for ongoing care of her sarcoidosis.

MILAN – A novel topical nonsteroidal treatment for psoriasis showed sufficient efficacy in phase 2b clinical trials to proceed to phase 3 studies, with improvements in severity, pain, and burning in adults with mild to moderate psoriasis.

At the end of 12 weeks of treatment, 29% of patients receiving the medication – which targets nerve pathways – experienced a decrease of at least 2 grades on the 5-point Investigator’s Global Assessment (IGA) scale, compared with 13% of those receiving the topical vehicle only (P = .036). A similar proportion of patients achieved 75% improvement on the Psoriasis Area and Severity Index (PASI-75)compared with those on vehicle alone (27% versus 13%; P = .045).

These findings were seen only with the less concentrated formulation of pegcantratinib, known as SNA-120 in the clinical trial program, said Paul F. Lizzul, MD, PhD, presenting the findings during a late-breaking abstract session at the World Congress of Dermatology.

Pruritus severity also dropped by about 60%, but the decrease did not differ significantly from the change seen with vehicle alone, said Dr. Lizzul, chief medical officer for Sienna Biopharmaceuticals, Westlake Village, Calif., which funded the study. He and his coinvestigators found this “interesting, surprising, and different from what we had seen previously,” he said. “We think a few things happened here,” including intensive querying on itch by means of daily diaries, a different approach than had been taken in the investigator’s earlier SNA-120 trials. “We think in this way we probably biased patients’ expectations, altering reporting on this subjective measure,” he added.

“There’s been really a lack of innovation in the topical world in developing nonsteroidal therapies for the majority of patients who are treated with topicals, said Dr. Lizzul. Keratinocytes within psoriatic plaques are known to have elevated levels of nerve growth factor (NGF), he explained. Together with tropomyosin receptor kinase A (TrkA), NGF is implicated in the pathogenesis of psoriasis; it stimulates keratinocyte hyperproliferation, is a factor in neurogenic inflammation, and contributes to pruritus. Upregulation of TrkA expression is seen in nerve fibers within pruritic psoriasis plaques as well, said Dr. Lizzul, senior author of the study. (The first author was Kristina Callis Duffin, MD, cochair of the dermatology department at the University of Utah, Salt Lake City.)

In fact, the pruritus that plagues many psoriasis patients, said Dr. Lizzul, may “serve as a clinical biomarker for elevated NGF/TrkA expression.” And certain clinical phenomena observed in psoriasis, such as the Koebner phenomenon and plaque resolution along the path of damaged nerves, provide other clues. “Clearly, astute clinicians going back many, many years have recognized the very important role that nerves and neuropeptides play in psoriasis,” he added.

SNA-120 targets NGF TrKA activity, and “achieves high local drug concentration in the skin, with low systemic availability,” he said.

The randomized, double-blind, vehicle-controlled study enrolled 208 adults with mild to moderate psoriasis (scores of 2 or 3 on the IGA), with pruritus of at least moderate intensity (5 or higher on a 10-point itch numeric rating scale, or I-NRS). The mean age of the patients was 50 years, and about half were male. Most (84%-90% across study arms) were white. At baseline, the mean I-NRS was 7.3-7.4, and the mean PASI score at baseline ranged from 5.9 to 6.5.


Patients were randomized to receive SNA-120 twice daily at either 0.05% (70 patients) or 0.5% (69 patients) in an ointment formulation, or vehicle alone twice daily (69 patients). Efficacy was tracked by measuring decrease in IGA by one or two grades, the number of patients achieving PASI-50 and PASI-75, reduction in itch, and a composite of a decrease of at least 2 grades on the IGA and having clear or almost clear skin.

The investigators also tracked reduction in burning and pain as measured on a 10-point numeric rating scale. Though itch scores didn’t differ significantly from reductions seen with the topical vehicle alone, pain and burning were both reduced significantly compared with vehicle by week 12 of the study (P = .033 for pain; P = .043 for burning).

All improvements were seen only with the lower dose, not the 0.5% dose of SNA-120, noted Dr. Lizzul, adding: “This is not necessarily surprising in the world of kinase inhibitors, where you can see these J-shaped or inverse dose-response curves.”

In addition to recording adverse events, the researchers assessed safety by obtaining laboratory values and electrocardiograms. Plasma SNA-120 levels at study weeks 2, 4, and 8 were obtained for pharmacokinetic analysis. Systemic uptake was virtually nil, and the safety profile overall was good, said Dr. Lizzul.

Next steps are phase 3 clinical trials that will evaluate global improvement as well as pain, burning, and itch in psoriasis, he noted.

Dr. Lizzul is an employee of Sienna Biopharmaceuticals, which is developing SNA-120.

NEWPORT BEACH, CALIF. – What can set off an allergic skin reaction? Some unusual suspects are wrinkle-free clothing, spinach salads, plywood, tires, and Italian food, according to dermatologist Jennifer H. Perryman, MD.

Here’s a closer look at the allergens highlighted by Dr. Perryman in a presentation at Skin Disease Education Foundation’s Women’s & Pediatric Dermatology Seminar:

Formaldehyde: It’s everywhere

“In general, formaldehyde is found on everyone in this room in two different places: preservatives in skin care products and in a lot of our clothing,” said Dr. Perryman, who practices in Greeley and Fort Collins, Colo.

The preservative is used in an even wider variety of products, including fluids used in industry (such as metalworking) and topical medications. But people are especially likely to encounter it in clothing – via formaldehyde textile resins – as well as in cosmetics, soaps, and lotions.

On the clothing front, Dr. Perryman said, formaldehyde textile resins have been used since the 1930s. They’re used to treat blends of synthetic and cotton fibers and bed sheets. Beware of “wrinkle resistant” and “permanent press” clothing (although not all have been treated with this resin). “Newer formaldehyde textile resins have less formaldehyde release, but they may be more expensive, and some industries may not use them,” she said.


Avoiding formaldehyde textile resins isn’t a simple matter.” You have to go out of your way to stay away from a polyester-cotton blend,” she said. “And don’t forget bedsheets,” she added, noting that the packaging on some sheets include information about cotton count, “but when you flip over the label it says it’s ‘50% cotton and 50% polyester or other.’ ”

Some patients will bring their own bedsheets to hotels so they don’t experience flares from hotel bedsheets, she added.

Other products can trigger this skin allergy. Beware, Dr. Perryman said, of formaldehyde exposure from paper, cardboard, cigarette smoke, processed wood products like plywood, foam housing and industrial insulation, embalming fluid and tissue fixatives, and some paints and adhesives.

What are the signs that someone may have a case of formaldehyde allergy? It may cause patchy generalized dermatitis, erythroderma, and nummular dermatitis. It may spare the hands, feet, and face because those parts of the body have less exposure to clothing, and it’s likely to especially affect body areas where clothing is tight. And for unknown reasons, this allergy is more common in the elderly, Dr. Perryman said.

Textile dye: Beware polyester

This allergy is mainly triggered by synthetic fabrics like polyester, rayon, and acetate, she noted. Darker colors are more allergenic. Clothes made of natural fibers such as cotton, silk, linen, and wool are alternatives. These are not dyed with these dyes, she said, adding that a reaction to wool will be from irritation, not from the dye.

Paraphenylenediamine: Keep an eye out for this dye ingredient

Paraphenylenediamine, which can trigger allergic reactions, is found in leather dye, fur dye, and some (but not all) hair dyes. Be aware that it can cross-react with other allergens like sulfonamide medications.

If a patch test turns up a reaction to “Black-Rubber Mix,” which includes paraphenylenediamine, consider whether the patient has exposure to the rubber in tires. Car mechanics may be affected by this allergy, Dr. Perryman said.

Neomycin: A drop of trouble

Allergy to the antibiotic neomycin can be triggered by exposure to gentamicin and tobramycin eye drops. Patients may believe they have an infection, Dr. Perryman said, so consider getting a culture. In some cases, an allergic reaction to neomycin may be incorrectly diagnosed as cellulitis.

Nickel: Not just a jewelry hazard

Jewelry and coins can trigger nickel allergies, but be aware that systemic nickel allergy can also trigger skin problems from a patient’s diet. It may be necessary to put patients on a low-nickel diet that avoids foods such as healthy grains, greens (especially spinach), nuts, legumes, and chocolate. “I always feel bad” putting patients on a restrictive diet, Dr. Perryman said, but it can be helpful to take 500 mg of vitamin C three times a day since it binds to nickel.

Cobalt: Watch the chocolate and coffee

Jewelry with cobalt can cause an allergic reaction. Dr. Perryman tells patients to buy an inexpensive “spot test” product online that detects whether jewelry has nickel or cobalt. Cobalt allergy can also trigger symptoms in patients exposed to “hard metal” industrial tools, cement, and masonry. Workers in the plastics and dye industries may be exposed too.

Like nickel, Dr. Perryman said, systemic cobalt allergy related to diet is also possible. The list of foods that contain higher levels of cobalt is long, and includes apricots, beans, beer, chocolate, coffee, nuts, tea, and whole-grain flour.

Dr. Perryman also mentioned several other allergens to keep in mind:

• Chromate can trigger reactions in people who wear leather shoes (the metal can be used in tanning). It can also cause problems in workers exposed to it via cement, bricks, drywall, and metal plating.
• Chromium picolinate, an over-the-counter supplement, can cause systemic dermatitis.
• Gold in jewelry can trigger an allergic reaction. Talk to patients about replating their jewelry, Dr. Perryman said.
• Rubber can trigger reactions due to exposure to rubber bands, makeup sponges, and rubber gloves (even nitrile ones). Be aware that both rubber and latex allergies may coexist and consider a blood test for latex allergy.
• Systemic balsam allergy related to an individual’s diet is possible. Tomato is an especially big villain on this front, along with citrus fruits, spices, cola, chili, and chocolate.

Dr. Perryman disclosed consulting work for IntraDerm. SDEF and this news organization are owned by the same parent company.

MILAN – Get ready for a “boxing match” over the next few years, as two treatment categories duke it out for their place in the therapeutic armamentarium for atopic dermatitis (AD), Thomas Bieber, MD, PhD, said in an oral presentation at the World Congress of Dermatology.

“In one corner of the ring you will have the biologics, and in the other corner of the ring, you will have the Janus kinase (JAK) inhibitors and some other small molecules,” said Dr. Bieber, medical director of dermatology and allergy, at University Hospital Bonn, Germany.

There will be no winner-take-all scenario, since AD is a heterogeneous disease for which a variety of treatments will be needed, Dr. Bieber noted. However, he said, there are clear differences in mode of action, safety, mode of application, price, and more that will be important as dermatologists weigh the choice of biologics versus JAK inhibitors for a specific patient.

“Currently, dupilumab is the only one that is on the market (in the European Union) and this molecule is really a revolution for us,” Dr. Bieber said at the meeting. “But we will see in the next years, many, many other molecules coming up.”

Beyond dupilumab (Dupixent), the interleukin-4 (IL-4) receptor alpha antagonist approved by the Food and Drug Administration in 2017, biologics under development include tralokinumab, lebrikizumab, and nemolizumab, among others. Development on the small molecule side includes agents such as ZPL-389, a histamine H4 receptor agonist, but is dominated by JAK inhibitors such as baricitinib(Olumiant), approved by the FDA in 2018 for rheumatoid arthritis; upadacitinib; and abrocitinib, according to Dr. Bieber.

There are advantages and disadvantages to each class of molecule, he said. For example, JAK inhibitors act very rapidly to control itch and improve exacerbations, while biologics are “much slower” and provide delayed control of inflammation, he said. In terms of safety, by contrast, biologics probably offer a “better” benefit-to-risk ratio, with no risk for drug-drug interactions and no monitoring needed, while JAK inhibitors appear to have a “narrow” therapeutic window, with a risk for drug-drug interactions and a need for some monitoring, he said.


JAK inhibitors come in a tablet formulation, which, from the patient perspective, may be more convenient and acceptable compared with repeated injections of biologics every 2 or 4 weeks, Dr. Bieber noted. Another point potentially in favor of JAK inhibitors is price: “I think the current situation tells us clearly that the biologics are the more expensive drugs, while the small molecules typically are much less expensive,” he said.

One theoretical advantage of biologics, he said, is the potential for disease modification, while the disease-modifying potential of JAK inhibitors is unclear, as of yet. “We have not had enough experience with all these molecules in order to understand how we can do that particular job, in terms of switching off the disease,” he said.

In terms of the need for patient stratification in the future, it’s a draw between biologics and JAK inhibitors, Dr. Bieber said. “You will not see any of these drugs doing 100 percent of the job in 100 percent of the patients, so to me, currently from my understanding of this disease, there is no one-size-fits-all molecule.”

Toward that end, machine learning and artificial intelligence may aid in evaluating large amounts of data to better understand AD phenotypes. “That’s really something that is a particular kind of challenge in the next years, in order to improve at-the-end drug development, and the management of our patients,” he concluded.

Dr. Bieber reported disclosures related to LEO Pharmaceuticals, Regeneron, and Sanofi.

NEWPORT BEACH, CALIF. – When it comes to acne in adult women, look past the jawline, beyond traditional medications, and toward greater control. That’s the message of a dermatologist who spoke at Skin Disease Education Foundation’s Women’s & Pediatric Dermatology Seminar.

“We should be aiming to get our patients to clear or almost clear, and we have the tools necessary to help that happen,” said Linda Stein Gold, MD, director of dermatology research at Henry Ford Hospital in Detroit.

Research suggests that acne is more common in adult women than in men, a gap that widens after age 29 years, she noted. Acne appears to affect 51% of women aged 20-29 years, she said, and prevalence dips to 15% in women older than 50 years.

About 80% of cases continue from adolescence, compared with about 20% that are new-onset during adulthood, she said. According to studies, she added, “most adult women have acne on multiple different areas of their face, not just the jawline. It’s similar to what we see in the adolescent population.”

Dr. Stein Gold offered these tips about treatment in this group of patients:
 

Inflammation

Researchers now consider that “all acne is inflammatory acne.” Be aggressive with anti-inflammatory treatment, and “continue even after the lesion is resolved” if needed to prevent scarring.

Oral contraceptives (OCs)

OCs can be helpful, but “we have to proceed with caution,” she said. A 2012 Cochrane Library review of 31 trials found that six combination OCs (COCs) “evaluated in placebo-controlled trials are effective in reducing inflammatory and noninflammatory facial acne lesions. Few important and consistent differences were found between COC types in their effectiveness for treating acne,” the review concluded (Cochrane Database Syst Rev. 2012 Jul 11;[7]:CD004425).

Results take time, however, and it “can take 3 months to see an effect, and 6 months for full effect,” Dr. Stein Gold noted.

There are multiple contraindications to the use of OCs, and they’ve been linked – controversially – to an increased risk of blood clots and breast cancer. However, risk of thrombosis also spikes – to significantly higher levels than with OC use – during pregnancy and the postpartum period, she said.
 

Spironolactone

This antihypertensive drug can be helpful, Dr. Stein Gold noted, although the one study in a 2009 Cochrane review that had acne as an outcome failed to find evidence of efficacy versus placebo (Cochrane Database Syst Rev. 2009 Apr 15;[2]:CD000194). Be aware of the boxed warning about links to cancer in rat studies, and consider the risk of potassium elevation in certain populations, she added. Watch the dose: fewer side effects are seen at 50-100 mg daily, although they’re still common, and it can take 3 months or more for improvements to appear, she said.

Truncal acne

Patients may be hesitant to mention they have acne on their chest and back. “They may not tell you about it, and you may not ask about it but [some patients] expect you to know about it and treat it,” Dr. Stein Gold said. She referred to trifarotene, a topical retinoid cream that, although not yet approved, appears to be safe and effective in treating acne on the face and trunk in phase 3 studies.

“Some people will say the trunk will get too irritated if you put a retinoid on it. But it absolutely can be used on the chest and back. The first thing I say to my patients is to expect to have redness and scaling for first 2 weeks. People pay money for that. It’s a chemical peel! It’s okay to have some sloughing; use an oil-free moisturizer.”

Dr. Stein Gold disclosed relationships with Galderma, Foamix, and Sol Gel (investigator, consultant); Valeant (consultant, speaker); and Dermira (investigator, speaker).

Watch the dose: fewer side effects are seen at 50-100 mg daily, although they’re still common, and it can take 3 months or more for improvements to appear, she said.

Truncal acne

Patients may be hesitant to mention they have acne on their chest and back. “They may not tell you about it, and you may not ask about it but [some patients] expect you to know about it and treat it,” Dr. Stein Gold said. She referred to trifarotene, a topical retinoid cream that, although not yet approved, appears to be safe and effective in treating acne on the face and trunk in phase 3 studies.

“Some people will say the trunk will get too irritated if you put a retinoid on it. But it absolutely can be used on the chest and back. The first thing I say to my patients is to expect to have redness and scaling for first 2 weeks. People pay money for that. It’s a chemical peel! It’s okay to have some sloughing; use an oil-free moisturizer.”

Dr. Stein Gold disclosed relationships with Galderma, Foamix, and Sol Gel (investigator, consultant); Valeant (consultant, speaker); and Dermira (investigator, speaker).

NEWPORT BEACH, CALIF. – When it comes to acne in adult women, look past the jawline, beyond traditional medications, and toward greater control. That’s the message of a dermatologist who spoke at Skin Disease Education Foundation’s Women’s & Pediatric Dermatology Seminar.

“We should be aiming to get our patients to clear or almost clear, and we have the tools necessary to help that happen,” said Linda Stein Gold, MD, director of dermatology research at Henry Ford Hospital in Detroit.

Research suggests that acne is more common in adult women than in men, a gap that widens after age 29 years, she noted. Acne appears to affect 51% of women aged 20-29 years, she said, and prevalence dips to 15% in women older than 50 years.

About 80% of cases continue from adolescence, compared with about 20% that are new-onset during adulthood, she said. According to studies, she added, “most adult women have acne on multiple different areas of their face, not just the jawline. It’s similar to what we see in the adolescent population.”

Dr. Stein Gold offered these tips about treatment in this group of patients:
 

Inflammation

Researchers now consider that “all acne is inflammatory acne.” Be aggressive with anti-inflammatory treatment, and “continue even after the lesion is resolved” if needed to prevent scarring.

Oral contraceptives (OCs)

OCs can be helpful, but “we have to proceed with caution,” she said. A 2012 Cochrane Library review of 31 trials found that six combination OCs (COCs) “evaluated in placebo-controlled trials are effective in reducing inflammatory and noninflammatory facial acne lesions. Few important and consistent differences were found between COC types in their effectiveness for treating acne,” the review concluded (Cochrane Database Syst Rev. 2012 Jul 11;[7]:CD004425).

Results take time, however, and it “can take 3 months to see an effect, and 6 months for full effect,” Dr. Stein Gold noted.

There are multiple contraindications to the use of OCs, and they’ve been linked – controversially – to an increased risk of blood clots and breast cancer. However, risk of thrombosis also spikes – to significantly higher levels than with OC use – during pregnancy and the postpartum period, she said.
 

Spironolactone

This antihypertensive drug can be helpful, Dr. Stein Gold noted, although the one study in a 2009 Cochrane review that had acne as an outcome failed to find evidence of efficacy versus placebo (Cochrane Database Syst Rev. 2009 Apr 15;[2]:CD000194). Be aware of the boxed warning about links to cancer in rat studies, and consider the risk of potassium elevation in certain populations, she added.

Cutaneous endometriosis should be considered as a diagnosis when umbilical lesions are present, especially if there is a history of pain flares during menses, according to Liza Raffi of the University of Southern California, Los Angeles, and associates.

The report, published in the International Journal of Women’s Dermatology, detailed a case of a woman aged 41 years who presented with a 5-month history of a painful firm subcutaneous nodule in the umbilicus and flares of pain during menstrual periods. Her past history indicated a missed miscarriage (removed by dilation and curettage) and laparoscopic left salpingectomy for a ruptured ectopic pregnancy.

At presentation, the woman reported undergoing fertility treatments including subcutaneous injections of follitropin beta and choriogonadotropin alfa.

Because of the patient’s history of salpingectomy and painful menstrual periods, her physicians suspected cutaneous endometriosis. An ultrasound was performed to rule out fistula, and then a punch biopsy of the nodule was performed. The biopsy showed endometrial glands with encompassing fibrotic stroma, which was consistent with cutaneous endometriosis, likely transplanted during the laparoscopic port site entry during salpingectomy.

The patient chose to undergo surgery for excision of the nodule, declining hormonal therapy because she was undergoing fertility treatment.

“The differential diagnosis of umbilical lesions with similar presentation includes keloid, dermatofibroma, dermatofibrosarcoma protuberans, and cutaneous metastasis of cancer,” the investigators wrote. “Ultimately, patients should be referred to obstetrics & gynecology if they describe classic symptoms including pain with menses, dyspareunia, and infertility and wish to explore diagnostic and therapeutic options.”

Ms. Raffi and associates reported they had no conflicts of interest. There was no external funding.
