To characterize the response to current medical therapies in children with ulcerative colitis, and to identify those factors that may predict the need for colectomy.
Retrospective chart review at two large pediatric inflammatory bowel disease centers.
We identified 171 subjects ranging in age from 1.5 to 17.7 years at diagnosis (mean 11.2 years). Mean follow-up was 5.1 years. Of these subjects, 43% had mild disease at presentation and 57% had disease that was classified as moderate or severe. After treatment 90% of the former group and 81% of the latter group had resolution of symptoms by 6 months. During any subsequent yearly follow-up interval, approximately 55% of the entire study population was symptom free, 38% had chronic intermittent symptoms, and 7% had continuous symptoms. A significantly lower risk of colectomy was noted for those with initially mild disease compared with those with moderate/severe disease. At 1-year the risk of colectomy was 1% among those with mild disease versus 8% with moderate/severe disease; at 5 years, the risk of colectomy was 9% in the mild disease group versus 26% in the moderate/severe disease group (p <0.03).
In the majority of pediatric subjects with ulcerative colitis remission is achieved in the first 6 months after therapy; thereafter disease is inactive in about 50% of patients during any given year of follow-up. Severity of disease at presentation is a significant risk factor for colectomy during the first 5 years of follow-up. Future management protocols with more aggressive initial therapy may be warranted in children with moderate/severe disease.
