Key clinical point: Risk for cutaneous infectious diseases is significantly higher in adults and children with atopic dermatitis (AD) than individuals without AD, with the risk for molluscum contagiosum being the highest.

Major finding: Patients with AD vs individuals without AD were at a significantly greater risk for molluscum contagiosum (adjusted odds ratio [aOR] 5.237), followed by impetigo (aOR 2.852), chickenpox (aOR 2.251), otitis media (aOR 2.243), eczema herpeticum (aOR 1.292), viral warts (aOR 1.105), and viral conjunctivitis (aOR 1.099; all P < .001) with molluscum contagiosum having the highest comorbidity (1.06%) and shortest onset duration (77.42 days).

Study details: Findings are from a nationwide population-based study including 70,205 patients with AD and individuals without AD.

Disclosures: This study did not receive any funding. The authors declared no conflicts of interest.

Study details: Findings are from a retrospective study including 73,816 children aged 0-14 years, of which 34,202 were exposed to antibiotics.

Key clinical point: Although food allergy (FA) is common among pediatric patients with atopic dermatitis (AD), immunoglobulin E (IgE) mediates the majority of instances and very few patients report food-triggered AD (FTAD), cautioning against unnecessary dietary restrictions.

Major finding: IgE-mediated FA was common in the overall cohort (55%) irrespective of the severity of AD (mild, 60%; moderate, 45%; severe, 57%), whereas FTAD was rare (3%) and diagnosed in only 2%, 6%, and 4% of patients with mild, moderate, and severe AD, respectively. In patients with AD only, more patients developed IgE-mediated FA vs FTAD (29% vs 5%).

Study details: Findings are from a retrospective study including 372 pediatric patients with AD, of which 29% had moderate AD and 18% had severe AD.

Study details: Findings are from a single-center, cross-sectional observational study including 502 Finnish patients with AD, of which 146, 231, and 125 patients had mild, moderate, and severe AD, respectively.

Key clinical point: A 52-week long treatment with difamilast ointment was well tolerated and reduced the severity of atopic dermatitis (AD) in Japanese adult and pediatric patients.

Major finding: Overall, 72.3% of adult patients and 89.0% of pediatric patients experienced treatment-emergent adverse events (TEAE) of mostly mild or moderate severity, and only 7.8% of adult patients and 3.5% of pediatric patients discontinued treatment due to TEAE. At week 52, 55.4% of adult patients and 73.5% of pediatric patients achieved ≥75% improvement in the Eczema Area and Severity Index.

Study details: Findings are from a long-term, open-label, phase 3 study including 166 adult (15-70 years) and 200 pediatric (2-14 years) patients with AD who initiated a 52-week treatment with 0.3% or 1% difamilast ointment.

Key clinical point: Acne caused by upadacitinib in adolescents and adults with moderate-to-severe atopic dermatitis (AD) is typically mild or moderate in severity and may not be considered a significant safety risk.

Major finding: Acne of mostly mild or moderate severity was reported by a higher proportion of patients receiving 15 mg upadacitinib (9.8%) and 30 mg upadacitinib (15.2%) vs placebo (2.2%), with no intervention required in 40.5% and 46.6% of patients receiving 15 and 30 mg upadacitinib, respectively. The improvement in quality-of-life scores was proportional to the decrease in AD severity and was similar in patients with or without acne.

Study details: Findings are from a post hoc integrated analysis of 3 phase 3 trials including 2583 patients with moderate-to-severe AD who were randomly assigned to receive upadacitinib (15 or 30 mg) or placebo as monotherapy or with concomitant topical corticosteroids.

Disclosures: This study was funded by AbbVie, Inc. Five authors declared being employees or stockholders of AbbVie. The other authors reported ties with various sources, including AbbVie.

Key clinical point: Dupilumab was more effective than topical corticosteroids (TCS) and cyclosporine in reducing the severity of atopic dermatitis (AD) and transepidermal water loss (TEWL), both in eczematous lesions and nonlesioned skin.

Major finding: At week 16, a higher proportion of patients receiving dupilumab vs cyclosporine or TCS achieved 50% improvement in the Eczema Area and Severity Index (EASI-50; 81.8% vs 28.6% or 40.0% respectively; P  =  .004). TEWL reduced with both dupilumab (P < .001) and TCS (P  =  .047) in eczematous lesions and with dupilumab in nonlesioned skin (P  =  .006) with dupilumab treatment being associated with achievement of EASI-50 (odds ratio 10.67; P  =  .026) and 50% improvement in TEWL (P  =  .004).

Study details: Findings are from a prospective, observational study including 46 patients with AD who received TCS (n = 10), cyclosporine (n = 14), or dupilumab (n = 22).

Key clinical point: Patients with moderate-to-severe atopic dermatitis (AD) who did not achieve Investigator's Global Assessment (IGA) 0/1 response with abrocitinib at week 12, still achieved clinically meaningful improvements in AD severity, itch, and quality of life.

Major finding: At week 12, a higher proportion of IGA nonresponders receiving 200 and 100 mg abrocitinib vs placebo achieved ≥ 75% improvement in the Eczema Area and Severity Index (41.0% and 27.0% vs 9.4%, respectively), ≥4-point improvement in itch (42.8% and 35.2% vs 18.2%, respectively), and ≥4-point improvement in Dermatology Life Quality Index (67.6% and 75.0% vs 49.5%, respectively) scores.

Study details: Findings are from a post hoc analysis of 1 phase 2b and 2 phase 3 (JADE Mono-1 and JADE Mono-2) trials including 548 patients with moderate-to-severe AD who were randomly assigned to receive abrocitinib (200 or 100 mg) or placebo and did not achieve IGA 0/1 response.

Disclosures: This study was funded by Pfizer Inc. Five authors declared being current or former employees and shareholders of Pfizer. The other authors reported ties with various sources, including Pfizer.

Key clinical point: Dupilumab led to clinically meaningful improvements in the severity of atopic dermatitis (AD) and was well tolerated in adolescents and children with moderate-to-severe AD.

Major finding: The mean improvement in the Eczema Area and Severity Index (EASI) was 59.6% at week 12-24 and 77.0% at week 36-48 (both P < .001), with all patients achieving ≥75% improvement in EASI score after a year or more of receiving dupilumab. Adverse events like conjunctivitis (5.6%) and joint pain (2.2%) were reported by 13.5% of patients.

Study details: Findings are from a retrospective observational study including 89 children and adolescents aged < 18 years with moderate-to-severe AD who initiated dupilumab treatment.

Disclosures: This study was funded by Pediatric Dermatology Research Alliance. Some authors declared serving as consultants or receiving research funds from several sources.
