Abstract
Multiple prior studies have looked at clinical and laboratory parameters in ulcerative colitis to predict prognosis, but individual histologic features of inflammation and their prognostic significance have not been well studied. The purpose of our study was to determine whether histologic features at presentation with acute severe colitis predict colectomy in pediatric patients. Patients were identified retrospectively through the gastroenterology and pathology databases. Demographic information, duration of disease, laboratory data, endoscopic appearance at scope, and histologic features of inflammation were reviewed along with medical therapies. Patients who underwent surgery within 90 days of hospitalization were compared to those who did not. Fifty patients with acute severe colitis, defined as Pediatric Ulcerative Colitis Activity Index ≥65, were included. Sixteen patients had colectomies performed within 90 days of presentation. No statistically significant difference was found between the surgery and no-surgery groups for patient age, albumin, hemoglobin, or C-reactive protein, though hemoglobin trended toward significance, P = .05. The endoscopic Mayo score and histologic features of inflammation (architectural changes...Continue Reading
