Comparative effectiveness of azathioprine in Crohn’s disease and ulcerative colitis: prospective, long‐term, follow‐up study of 394 patients

Abstract

Our results confirm the effectiveness of AZA in inflammatory bowel disease, not only in the short term but also in the long term, resulting in a steroid sparing effect and in both a reduction in the number of hospitalizations and surgical procedures. AZA is similarly effective for both CD and UC patients.
