Atopic Dermatitis

Key clinical point: A significant association was observed between atopic dermatitis (AD) and poorer cognitive function in men, and familial characteristics exerted a confounding effect on this association.

Major finding: After effectively controlling for familial environmental confounding factors and addressing genetic influences, AD in men was significantly associated with poorer cognitive function (regression coefficient −0.04; 95% CI −0.07 to −0.003).

Study details: This sibling-comparison study included 1,687,038 men who underwent a military conscription examination at 17-22 years of age, of which 25,995 were diagnosed with AD.

Disclosures: This study was sponsored by grants from the Swedish Research Council for Health, Working Life, and Welfare (Forte) and the UK Economic and Social Research Council. L von Kobyletzki declared being a consultant for and receiving research funding from various organizations. The other authors declared no conflicts of interest.

Key clinical point: Allergic contact dermatitis (ACD) is an important comorbidity in patients with atopic dermatitis (AD) and leads to the maintenance and aggravation of their dermatosis, with a high frequency of ACD observed to textile dyes, isothiazolinones, and fragrances.

Major finding: Contact sensitization was significantly associated with facial involvement (P = .04) and a longer duration of AD (P = .005). The most frequent allergen was textile dye mix (24.70%) followed by nickel (20.21%), cobalt (12.70%), and methylchlorisothiazolinone+methylisothiazolinone (8.50%). The avoidance of relevant allergens led to a significant reduction in the Scoring of Atopic Dermatitis (SCORAD) scores at 6 months (P < .001).

Study details: This longitudinal prospective study included 93 patients with AD (age > 2 years) who were patch-tested with the 2019 European baseline series and the corticosteroid series, 60.2% of whom had positive patch test results.

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

Key clinical point: Dupilumab led to a rapid improvement in disease control that was sustained through 2 years and showed an acceptable safety profile in adult and adolescent patients with moderate-to-severe atopic dermatitis (AD).

Major finding: Dupilumab led to an improvement in the mean Eczema Area and Severity Index score at 3 months (5.5) and 24 months (2.6) compared with baseline (16.1), with a mean absolute change from baseline to 24 months being −14.0. No new safety signals were observed.

Study details: Findings are from a 2-year interim analysis of real-world data from the PROSE registry study including 764 patients with moderate-to-severe AD (age ≥ 12 years) who initiated dupilumab.

Disclosures: The PROSE registry is sponsored by Sanofi and Regeneron Pharmaceuticals Inc. Three authors declared being employees of or holding stock or stock options in Sanofi or Regeneron.

Key clinical point: Atopic dermatitis (AD) is associated with a lower risk for venous thromboembolism (VTE) than several rheumatologic and gastrointestinal immune-mediated inflammatory diseases (IMID).

Major finding: Patients with AD vs AD-matched control individuals did not have a higher risk for VTE (adjusted hazard ratio [aHR] 0.96; 95% CI 0.90-1.02). Compared with patients having AD, those with Crohn’s disease (aHR 1.71; 95% CI 1.47-1.99), rheumatoid arthritis (aHR 1.57; 95% CI 1.43-1.72), ulcerative colitis (aHR 1.84; 95% CI 1.63-2.09), and ankylosing spondylitis (aHR 1.45; 95% CI 1.03-2.03) had higher risks for VTE.

Study details: This retrospective observational cohort study analyzed 2,061,222 adult patients with IMID, including 1,098,633 patients with AD who were matched with 1,098,633 control individuals without IMID.
