Alefacept treatment has been shown in several multicentre studies to result in prolonged post-treatment remission periods (median duration 241 days). This communication describes the clinical responses of 10 patients to multiple courses of 12 weekly intramuscular injections with alefacept given in combination with available antipsoriatic treatments. It was shown that in this group of 10 patients with moderate-severe psoriasis, 8 were no longer candidates for any more long-term continuous systemic treatment with methotrexate or acitretin, 7 had no options for UVB/PUVA courses and 8 were not suitable for treatment with cyclosporine. In 5 out of these 10 patients alefacept had resulted in a considerable long-term improvement with only mild disease expression, which lasted one year or longer. Patients indicated that these responses were outstanding as compared to the troublesome years before. Another patient reported a major improvement in the quality of life by reduction of itch. In two patients alefacept vastly enhanced the efficacy of dithranol treatment, as compared to previous treatments. Another patient was able to discontinue methotrexate without relapsing during alefacept, in contrast to severe rebound episodes following discontinuation of methotrexate in the past. The long-term responses of 8 out of the 10 patients described in this report indicate that alefacept, in the context of individualised care of patients with moderate to severe psoriasis, can have an important contribution. In particular, the long-term response after stopping alefacept makes this treatment a valuable tool, achieving prolonged disease control in at least some patients with moderate to severe psoriasis.
