Rapid improvement of pyoderma gangrenosum after treatment with infliximab.

Infliximab, a novel chimeric anti-tumor necrosis factor-alpha (TNF-alpha) monoclonal antibody, has been increasingly used in the treatment of pyoderma gangrenosum. However, an established dosing regimen is lacking in the published literature. A variety of dosing regimens have been suggested, including a treatment schedule similar to that of psoriasis. The authors report a case of rapid response to infliximab in a patient with pyoderma gangrenosum associated with inflammatory bowel disease utilizing a dosing regimen similar to that used for psoriasis.
