Key clinical point: Risk factors affecting oral Janus kinase inhibitor (JAKi) treatment were prevalent among adult patients with atopic dermatitis (AD), especially older individuals, thus necessitating careful risk assessment among patients before JAKi therapy initiation.

Major finding: Nearly half (49.5%) of the patients with AD at some point had at least one risk factor that could affect JAKi treatment and most (60.3%) patients age ≥ 65 years had at least three risk factors. The recorded non-modifiable risk factors included cancer (5.6%), smoking history (15.6%), age ≥ 65 years (12.4%), and major adverse cardiovascular events (2.6%).

Study details: This cross-sectional study included adult patients with AD from the Danish national registers (n = 18,618) and Danish Skin Cohort (n = 3573).

Disclosures: This study did not disclose the source of funding. Several authors declared receiving research support, lecture honoraria, or consulting honoraria from or serving as speakers or advisory board members for various organizations.

Key clinical point: Pathogenic filaggrin (FLG) variants do not affect the effectiveness of dupilumab treatment in patients with atopic dermatitis (AD).

Major finding: No clinically relevant differences were observed in the Eczema Area and Severity Index, Investigator Global Assessment, Numeric Rating Scale for pruritus, and total Patient Oriented Eczema Measure (POEM) scores between patients with and without pathogenic FLG variants at week 16 or 52. However, patients with bi-allelic pathogenic variants vs wild-type alleles had significantly higher POEM dryness scores at week 16 (P = .002) and week 52 (P = .016).

Study details: This prospective observational study included 285 adult patients with AD from the Dutch BioDay Registry who had received dupilumab for 16 weeks or more and underwent genomic variant analysis for FLG.

Key clinical point: Upadacitinib resulted in a good survival rate and was effective in patients with moderate to severe atopic dermatitis (AD) after over a year of continuous treatment, with no single characteristic of the study population being significantly associated with drug discontinuation.

Major finding: The drug survival rates at 1 and 1.5 years were 91.5% and 80.2%, respectively. The main reasons for discontinuation, occurring in 7.7% of patients, were adverse effects and ineffectiveness. However, no specific patient characteristics, such as sex or age at AD onset, showed a significant association with drug discontinuation.

Study details: This real-world retrospective study included 325 adult patients with moderate to severe AD who were treated with upadacitinib for at least 4 weeks and up to 72 weeks.

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

Key clinical point: In infants and young children with atopic dermatitis (AD), dupilumab treatment with concomitant low-potency topical corticosteroids (TCS) does not increase infection rates and is associated with a reduced risk for bacterial and non-herpetic skin infections.

Major finding: Patients receiving dupilumab vs placebo had similar total infection rates week 16 (rate ratio [RR] 0.75; P = .223) and a significantly lower frequency of non-herpetic skin infections (RR 0.46; P = .047) and bacterial infections (RR 0.09; P = .019).

Study details: This post hoc analysis of the phase 3 LIBERTY AD PRESCHOOL trial included 162 patients (age 6 months to 5 years) with moderate to severe AD who were randomly assigned to receive 200 or 300 mg dupilumab (n = 83) or placebo (n = 79) every 4 weeks with concomitant low-potency TCS.

Key clinical point: Dose reduction of 300 mg dupilumab was successfully achieved by dose spacing to >2 weeks without loss of efficacy in most patients with persistently controlled atopic dermatitis (AD), regardless of previous exposure to biologics and Janus kinase inhibitors (JAKi).

Major finding: At a median follow-up of 10 months, dose spacing of 300 mg dupilumab without loss in efficacy was achieved in 35 of 37 patients with controlled AD receiving dupilumab treatment for a median duration of 20.1 months. Similar findings were observed in patients with vs without previous exposure to biologics or JAKi (P > .05).

Study details: Findings are from a retrospective cohort study including 37 patients with controlled AD for more than a year, who were treated with 300 mg dupilumab at intervals > 2 weeks, and of whom 7 patients were classified as non-naive to biologics and JAKi.

Major finding: At week 52, 64% of patients showed a decrease in disease severity, achieving a Physician Global Assessment score of 0 or 1 compared with a score of 3 or 4 at baseline. No adverse effect on current malignancy or recurrence of prior malignancy was reported with dupilumab use.

Key clinical point: Skin care by washing with water alone is not inferior to washing with a cleanser for the maintenance of remission in children with atopic dermatitis (AD) during the summer.

Major finding: The mean modified Eczema Area and Severity Index scores at 8 ± 4 weeks were similar in children who washed their upper and lower limbs with water and those who used a cleanser (0.00 and 0.15, respectively; P = .74). No difference was observed in the occurrence of skin infection, Patient-Oriented Eczema Measure, and other secondary outcomes with water vs cleanser use (all P > .05).

Study details: This noninferiority study included 43 children (age < 15 years) with AD having controlled eczema following regular steroid ointment application, who washed the randomly assigned left or right limb with a cleanser and the other limb with water alone.

Key clinical point: A significant positive, dose-dependent association was observed between air quality index (AQI) and the incidence of atopic dermatitis (AD).

Major finding: The participants were classified into four AQI value quantiles (Q), with the mean AQI values from the lowest Q1 to the highest Q4 being 69.0, 78.9, 89.8, and 104.0, respectively. Compared with Q1, the risk for AD increased significantly in Q2 (adjusted hazard ratio [aHR] 1.29; 95% CI 1.04-1.65), Q3 (aHR 4.71; 95% CI 3.78-6.04), and Q4 (aHR 13.20; 95% CI 10.86-16.60). An increase of one unit in the AQI value increased the risk for AD by 7%.

Study details: This cohort study included 21,278,938 individuals without AD, with the long-term average AQI value before AD diagnosis being calculated and linked for each of the individuals.

Disclosures: This study was sponsored by grants from the Ministry of Science and Technology, Taiwan, Republic of China. The authors declared no conflicts of interest.

Key clinical point: Dupilumab monotherapy is safe and leads to rapid and significant improvements in disease signs and symptoms in patients with hand and foot (HF) atopic dermatitis (AD).

Major finding: At week 16, a significantly higher number of patients receiving dupilumab vs placebo achieved an HF Investigator’s Global Assessment score of 0 or 1 (P = .003) and ≥4-point reduction in HF Peak Pruritus Numeric Rating Scale score (P < .0001), with the difference between groups evident from weeks 4 and 1, respectively. Safety was consistent with the known dupilumab profile.

Study details: Findings are from the phase 3 LIBERTY-AD-HAFT study, which included 106 adults and 27 adolescents (≥ 12 to < 18 years) with moderate to severe HF AD who were randomized (1:1) to receive dupilumab or placebo.

Disclosures: This study was funded by Sanofi and Regeneron Pharmaceuticals Inc. Ten authors declared being employees or shareholders of Sanofi or Regeneron. The remaining authors, except Ewa Sygula, declared serving as investigators, consultants, etc., for or receiving personal fees, grants, honoraria, etc., from Sanofi, Regeneron, or others.

Key clinical point: Dupilumab monotherapy is safe and leads to rapid and significant improvements in disease signs and symptoms in patients with hand and foot (HF) atopic dermatitis (AD).

Key clinical point: A significant causal relationship was observed between atopic dermatitis (AD) and autoimmune diseases in children, and this was supported by the presence of shared genetic factors.

Major finding: At a follow-up of 12 years, children with vs without AD had a significantly increased risk for autoimmune diseases (adjusted hazard ratio [aHR] 1.27; 95% CI 1.23-1.32), particularly psoriasis vulgaris (aHR 2.55; 95% CI 2.25-2.80). Boys were significantly more susceptible to autoimmune diseases than girls (P for interaction = .04). Sixteen shared genes were identified between AD and autoimmune diseases and were associated with comorbidities, such as asthma and bronchiolitis.

Study details: This large-scale cohort study included 39,832 children with AD born between 2002 and 2018, who were matched with 159,328 children without AD.

Disclosures: This study was supported by the Korea Health Technology R&D. The authors declared no conflicts of interest.
