Infliximab in Crohn's disease-associated toxic megacolon.

Refractory medical treatment of Crohn disease-associated toxic megacolon usually requires surgery, which carries substantial morbidity and mortality. We report a case of a woman with steroid and antibiotic-refractory fulminant Crohn colitis and ileitis, complicated by a toxic megacolon, who was successfully treated with infliximab. Infliximab induced rapid clinical response and remission, thereby avoiding emergency (ileo) colectomy. This is the first report of treatment of Crohn disease-associated toxic megacolon with infliximab.
