Dupilumab is the first biological treatment approved for moderate-to-severe atopic dermatitis (AD). Efficacy and safety have been demonstrated in clinical trials, but real-life data is still limited. The objective of this study was to retrospectively evaluate Dupilumab treatment in AD patients in a real-life clinical setting. Effectiveness and safety outcomes were collected at baseline and after 2, 6, 10, 24, 39, and 52 weeks by using clinical scores for disease activity, as well as serological markers. Ninety-four patients from five dermatological hospitals were included. After 24 weeks of treatment, the median Investigator Global Assessment (IGA) and Eczema Area and Severity Index (EASI) showed a significant reduction compared to baseline (3.9 ± 0.7 vs. 1.4 ± 0.8 and 26.5 ± 12.5 vs. 6.4 ± 6.5). Interestingly, we observed rosacea-like folliculitis as an unexpected side effect in 6.4% of patients. Dupilumab proves to be an effective and well-tolerated treatment under real-life conditions. The occurrence of rosacea-like folliculitis warrants further mechanistic investigation.

Narrow-band UVB phototherapy appears to be a very effective and safe treatment option for patients with severe seborrhoeic dermatitis.

A 3-year-old boy presented with a generalized bullous disease, clinically strongly indicative of chronic bullous disease of childhood (CBDC). The diagnosis was confirmed by histopathology and further verified by several immunological and biochemical examinations. Direct immunofluorescence (IF) of perilesional skin revealed in vivo bound IgA-autoantibodies (aabs) in a linear pattern along the basement membrane zone; indirect IF revealed circulating IgA-aabs bound to the roof of "split skin" preparations of healthy human skin; immunoblotting of epidermal protein extracts showed that the aabs bound to a 97KD/120KD protein. Therapy with 4,4'-diaminodiphenylsulfone (DADPS, 2 mg/kg /daily), combined with prednisolone for the first month, was initiated, and promptly led to complete remission. Two attempts to stop DADPS treatment after 3 and 5 years of continuous therapy were followed by prompt recurrences. The boy is now 8 years old; with continuous DADPS therapy (1 mg/kg body weight/d), he displays regular physical and intellectual development.
