MedPage Today  (1/28, Walsh) reported, "New psoriasis treatment guidelines  from the National Psoriasis Foundation" have been published in the January Archives of Dermatology. "The guidelines, which summarize the benefits and drawbacks of systemic agents currently in use for psoriasis, are an update of earlier recommendations developed in Canada." The guidelines note that "conventional drugs such as methotrexate and cyclosporine often are effective, but have significant toxicities, including liver problems with methotrexate and kidney problems with cyclosporine."
