Introduction: Ultraviolet-B radiation is known to be effective and safe in childhood and adolescent psoriasis, but little has been published on the combined use of psoralen with ultraviolet-A radiation. The aim of this work is to assess the efficacy and short-term safety of systemic photochemotherapy in an adolescent population.Methods: Relevant clinical data on psoriatic patients aged 13 to 17 was retrospectively collected and analyzed. The sample population included twenty patients, eighteen with moderate to severe plaque-type psoriasis and two with guttate psoriasis.Results: Nine patients were treated with one single cycle and the remaining eleven with two cycles, in association with systemic therapies in 52%. Total improvement rate was 86.2%, with an average of 16.7 treatments per patient and a mean total cumulative dose of 174.0 J/cm2. The mean time for disease relapse was 4.3 months and two patients (10%) did not experience relapse during one-year follow-up. Side effects occurred in three patients (15%), namely nausea and erythema.Conclusions: Photochemotherapy showed to be highly effective in our adolescent population. Side effects were minor and none led to therapy discontinuation. Carcinogenic potential of ultraviolet-A radiation might be an important limitation. Further studies are warranted to access long-term safety of photochemotherapy.
