Abstract BACKGROUND: Evidence on effectiveness and safety of methotrexate (MTX) in pediatric psoriasis is scarce. OBJECTIVES: To study the effectiveness and safety of MTX in pediatric plaque-type psoriasis and its influence on quality of life (Qol) in daily clinical practice. METHODS: Subset analysis of prospectively collected data extracted from the Child-CAPTURE registry, a single center, longitudinal, long-term, observational daily practice cohort of pediatric psoriasis patients. A maximum dose between 0.14 and 0.63 mg/kg once weekly was prescribed in 25 children. Primary endpoints were percentages of patients with ≥ 75\% improvement in the Psoriasis Area and Severity Index (PASI) at week 12 and 24. RESULTS: PASI75 was achieved in 4.3\% and 33.3\% of patients at week 12 and 24, whereas 40\% and 28.6\% reached PASI 75 at week 36 and 48. Median PASI and body surface area decreased from 10.0 (range 3.8-42.4) and 11.0 (range 3.5-72.0) at baseline to 4.3 (range 0-19.8) and 2.6 (range 0.0-39.6) at week 24, respectively. Physician Global Assessment improved significantly from 3.0 to 1.2 at week 24. A significant decrease in Children's Dermatology Life Quality Index from 9.0 to 3.8 at week 24 was found. Most reported adverse events were severe nausea (n = 5), infections requiring antibiotics (n = 5) and tiredness (n = 4). CONCLUSIONS: MTX shows a positive effect on PASI scores, improves Qol and has a reasonable safety profile.
