Current therapeutic recommendations: infliximab for ulcerative colitis.

Randomized, controlled studies have shown that infliximab, the chimeric anti-tumor necrosis factor alpha (TNF-alpha) antibody, is effective for the treatment of active and fistulizing Crohn's disease. Because infliximab is beneficial in patients with Crohn's disease, in whom other therapies have failed, it has been postulated that infliximab may also be helpful in patients with ulcerative colitis. Many investigators have studied the effectiveness of infliximab in ulcerative colitis, mainly in patients who are refractory to corticosteroids.
