Successful treatment of genital and facial psoriasis with tacrolimus ointment 0.1%.

Tacrolimus is an immunomodulatory agent that inhibits the activation and maturation of T-cells and blocks transcriptional activation of several cytokine genes. It also interferes with the function of Langerhans cells, basophil cells and mast cells. Recent studies have demonstrated the efficacy of topical tacrolimus in inflammatory skin disorders. Our objective was to assess the efficacy of topical treatment with tacrolimus ointment 0.1% in patients with psoriasis on the anogenital region and the face. Included in the study were 10 patients with a long-standing history of genital and facial psoriasis, partially controlled with periodic use of topical corticosteroids. Tacrolimus ointment 0.1% was applied twice daily for 10 days. The patients were followed-up every 3 weeks for a total period of 12 weeks. The severity of psoriasis was evaluated in all patients at baseline (day 0) and at the end of weeks 3, 6, 9 and 12. Clinical severity of erythema, scaling, infiltration and lesional extent were graded using a 0-3 scale indicating none, mild, moderate and severe expression, at baseline and at follow-ups. An overall severity score of 0 (clear), 1-4 (mild), 5-8 (moderate) or 9-12 (severe) was then assigned to each patient by adding the scores for the above parameters. On each visit, every patient was evaluated clinically. The decision to reapply the drug was determined by the clinical response of each patient at each visit. At the end of the study, patients also assessed efficacy, safety and tolerance after topical application of tacrolimus ointment using a 0-5 scale for each parameter: A marked improvement was noticed in all patients at the end of the first week without drug-related adverse effects. There were 15 recurrences during the 12-week period in all patients. In conclusion, tacrolimus ointment 0.1% seems to represent a safe new option for the treatment of genital and facial psoriasis. Further studies are probably needed to specify the therapeutic dosage and maintenance therapy
