Successful treatment of severe recalcitrant psoriasis with combination infliximab and methotrexate

Plaques of psoriasis contain increased levels of cytokines, including tumour necrosis factor-alpha (TNF-alpha), which are thought to be essential to the maintenance of the psoriatic process. We report the successful treatment of severe, recalcitrant psoriasis when infliximab (a monoclonal antibody to TNF-alpha) was used in combination with methotrexate.
