In this acne segment, Raegan Hunt, MD, described pediatric cases involving the etiology and clinical findings for neonatal “acne,” infantile “acne,” and mid-childhood “acne.” Additionally, Dr. hunt listed available acne therapies for this population, such as benzoyl peroxide, topical retinoids, erythromycin, and azelaic acid, as well as the many ways isotretinoin can be given to infants and babies (for more difficult cases). Following, Dr. Hunt reviewed the cases of a 2- and 4-year-old with mid-childhood “acne” to depict how this skin presentation tends to be indicative of other underlying disorders, typically of the endocrine variety. Pre-adolescent acne was the next skin condition covered by Dr. Hunt. To end, Dr. Hunt explored acne in transgender youth, specifically the risk of acne development and/or exacerbation of acne with gender-affirming treatments.

Using the case of a patient with moderate-to-severe acne that affected different parts of the body and became more severe as they aged, Hilary Baldwin, MD, described methods and factors (i.e., age, sex, adherence, and child-bearing and menopausal years) to consider when making treatment and management decisions for this skin condition. Per Dr. Baldwin, the treatment was modified when the patient became pregnant, suffered from post-partum depression, and endured perimenopausal years. Through this case, Dr. Baldwin discussed increasing C. acnes resistance rates and the decrease of oral antibiotic development, as well as the importance of developing an “exit” strategy for patients with moderate-to-severe acne being treated with an oral antibiotic to avoid C. acnes resistance. Tazarotene 1.5% lotion at 11 years, combination benzoyl peroxide 2.5% and adapalene at 13 years, trifarotene at 17 years, isotretinoin at age 18 years, spironolactone at age 27 years, and trimethoprim/sulfamethoxazole at 31 years were some of the patient’s treatments mentioned by Dr. Baldwin.

Switching from acne to rosacea, Julie Harper, MD, highlighted why patient-reported signs and symptoms, triggers, and treatment goals should be kept in mind when forming treatment strategies for patients with this skin condition. Using clinical data and patient outcomes, Dr. Harper reported select therapies for elements of rosacea, such as beta-blockers (carvedilol, nadolol, and propranolol) for flushing, botulinum toxin for facial erythema, brimonidine 0.33% gel (and/or in conjunction with ivermectin) for persistent facial erythema, and oxymetazoline 1% cream for inflamed papules and pustules and facial erythema.

Bruce Strober, MD, PhD, explored new psoriasis therapies and data, starting with head-to-head studies on various interleukin (IL)-17 and IL-23 inhibitors. To explain the tailoring of secukinumab dosing, Dr. Strober evaluated available clinical studies on its efficacy and safety. Psoriasis Area and Severity Index (PASI) and Static Physician’s Global Assessment (sPGA) scores and overall responses for pediatric patients with psoriasis treated with ixekizumab or secukinumab were then highlighted. Using patient data, Dr. Strober discussed and compared the use of ixekizumab for the treatment of nail psoriasis. Following this, Dr. Strober focused on IL-23 inhibitors in patients chronic plaque psoriasis, mainly using data from RESURFACE 2 trial, wherein patients were given tildrakizumab, VOYAGE 1 trial, wherein researchers compared guselkumab and adalimumab use, and ultlMMa 1 and 2 trials, which tested the efficacy of risankizumab. Next, Dr. Strober further analyzed the efficacy, safety, and PASI score data of apremilast from the ESTEEM and ADVANCE trials. Dr. Strober then provided updates for the tyrosine kinase 2 (TYK2)-inhibitor, deucravacitinib, comparing it with apremilast clinical outcomes. To end this segment, Dr. Strober shared efficacy and safety data on bimekizumab and roflumilast.

Following Dr. Strober, Martin Bergman, MD, used patient photos and cases to demonstrate the various presentations of psoriatic arthritis and how symptoms and related conditions affects different parts of the body. Additionally, Dr. Berman provided other physicians with screening tools for detecting psoriatic arthritis. Using the American College of Rheumatology (ACR) vaccination guidelines, Dr. Bergman discussed how patients treated with conventional synthetic DMARDs or biologics and Janus kinase (JAK)-inhibitors are considered immunocompromised and should opt for the COVID-19 vaccine; treatment management for these populations were also covered. Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) treatment recommendation updates ended this portion of the presentation.

Atopic Dermatitis Update 2021

by Vikash S. Oza, MD, and Matthew Zirwas, MD

For the last segment of Day 1, Vikash Oza, MD, provided pediatric atopic dermatitis updates, beginning with key concepts within this population and comparisons with adult atopic dermatitis. According to Dr. Oza, factors such as incident rates, symptom prevalence, and immunophenotype vary between pediatric and adult patients with atopic dermatitis. Using data from clinical studies, Dr. Oza then explored skin barrier differences between young and adult patients, and the use of emollients in the prevention of eczema and atopic dermatitis. However, many food allergies have been linked to early emollient use, according to Dr. Oza, which were likely due to the transmission of allergens from parent’s hands. It was established that bathing frequency and quality of water could play a role in eczema development during the early years of life as well. Next, Dr. Oza examined the influence of breast feeding in the prevention of atopic dermatitis, but ultimately, this relationship requires more research. Ending this portion of the presentation, Dr. Oza reviewed patient cases that prompted the questioning of initial diagnoses; these cases included Netherton syndrome, hyper IgE syndrome, and poor response to strong topical steroids.

Next, Matthew Zirwas, MD, presented atopic dermatitis updates in adult populations. Delays in the FDA-approval of certain JAK inhibitors for the treatment of atopic dermatitis, Phase 2 and 3 data on upadacitinib, baricitinib, abrocitinib, and tralokinumab, and studies comparing the efficacy and safety of these treatments with dupilumab in patients with atopic dermatitis were covered here. Following this, Dr. Zirwas shared a summary of recommendations for dupilumab and the above therapies.
