Popis: Background & Aims Despite highly effective therapies, many children develop medically refractory ulcerative colitis (UC) and undergo proctocolectomy with ileal pouch anal anastomosis (IPAA). There is little real world evidence regarding IPAA outcomes in pediatric UC patients. We sought to determine the risk of pouchitis, recurrent pouchitis, and change in diagnosis to Crohn’s disease (CD) within two years of IPAA surgery among pediatric patients with UC using a large, geographically diverse insurance claims database. Methods Within the IQVIA Legacy PharMetrics Adjudicated Claims Database, we identified pediatric patients (age Results A total of 68 patients with an IPAA with at least two years of continuous health plan enrollment following surgery were identified. Among all patients undergoing surgery, the median age was 15 years (interquartile range 11.5–16), with 29 (43%) female patients. In the first 2 years following IPAA, the cumulative incidence of pouchitis was 54%. Characteristics and prior medical treatments in patients without pouchitis and with ≥ one episode of pouchitis were similar (Table 1). The cumulative incidence of recurrent pouchitis during this period was 22%. The cumulative incidence of a new diagnosis of CD in the two years after IPAA for UC was 9%. Conclusions In a geographically diverse cohort from the United States, 54% of pediatric patients undergoing proctocolectomy with IPAA for UC developed pouchitis within the first two years after surgery. Furthermore, 9% had a change in diagnosis to CD. These data indicate that for many pediatric UC patients, surgery is non-curative and patients continue to have a substantial burden of illness. Future efforts should attempt to identify novel, actionable, predictors of pouchitis in this population.
