Abstract

In contrast to the treatment of rheumatoid arthritis, there are few data in psoriasis vulgaris regarding the efficacy of combining tumor necrosis factor (TNF)-alpha inhibitors and methotrexate (MTX). Indeed, combination of MTX with different TNF-alpha inhibitors may enhance the therapeutic effects and reduce side effects because of less dosage of the single agent. The present authors present five cases in which low-dose MTX combined with TNF-alpha inhibitors led to impressive improvement in Psoriasis Area and Severity Index scores. Here, the present authors initiated very low-dose MTX treatment in addition to existing TNF-alpha inhibitor therapy to exhaust current therapy and prevent premature change of the biologic. These observations support the concept of combined treatment in recalcitrant cases of psoriasis, which need a systemically lifelong treatment when both first-line and second-line monotherapies fail to provide sufficient clinical response.
