BACKGROUND: Severe attacks of ulcerative colitis have a high risk of colectomy. AIMS: To evaluate the effects of standard medical management and to identify the clinical and laboratory variables capable of predicting the clinical outcome. MATERIALS AND METHODS: Prospective study monitoring the clinical and laboratory variables in 67 patients with severe colitis. Therapy consisted of prednisone, cyclosporin if no response, and azathioprine for maintenance. End-points were colectomy or remission. Logistic regression analysis was applied for statistical evaluation. RESULTS: Fourteen (20%) patients required colectomy, 34 (50%) patients achieved remission with steroids, 25 (37%) patients received cyclosporin, 19 (76%) with benefit. Increased body temperature, pulse rate, sedimentation rate and C-reactive protein levels on admission were significantly associated with colectomy. Sedimentation rate greater than 75 mm/h and body temperature exceeding 38 degrees C at admission had 4.6- and 8.8-fold increased risk of colectomy. Less than 40% reduction in the bowel movements within 5 days predicted no response to steroids. Azathioprine maintained remission in 70% of the patients. CONCLUSIONS: Elevated sedimentation rate and fever at day 1 best predict colectomy in severe colitis. Less than 40% reduction in the bowel movements at day 5 predicts no response to steroids. Cyclosporin has a high rate of success in acute attacks and azathioprine in maintaining remission.
