Abstract
OBJECTIVE: Extraintestinal manifestations in irritable bowel disease (IBD), Crohn's disease and ulcerative colitis are reported in different system of the body. We aimed to investigate the factors determining disease severity and evaluate extraintestinal manifestations in patients with irritable bowel disease based on disease activity scoring system. METHODS: This cross-sectional study was conducted on all patients with irritable bowel disease referred to clinic and gastroenterology ward of (XXX). Medical history, gastrointestinal complications and incidence of extraintestinal manifestations were recorded. Disease severity in ulcerative colitis was rated based on PUCAI (Pediatric Ulcerative Colitis Activity Index) score and in Crohn's disease was calculated based on PCDAI (Pediatric Crohn's Disease Activity Index) score. RESULTS: Of 73 children included in our study, 54.80% were diagnosed with ulcerative colitis and 45.20% were diagnosed with Crohn's disease. The most prevalent symptom was weight loss (81.81%), diarrhea (72.72%) and abdominal pain (69.69%) in Crohn's diseases and bloody diarrhea (80%), abdominal pain (77.5%) and weight loss (57.5%) in ulcerative colitis. The average of PCDAI score was 43.44 and PUCAI score was 35.62. The most prevalent extraintestinal manifestation of the disease was arthritis in 7 Crohn's disease patients (21.21%) and 5 patients (12.5%) with ulcerative colitis, oral plague in 5 patients (15.15%) with Crohn's disease and erythema nodosum in 2 patients (6.06%) with Crohn's disease. CONCLUSION: The severity of oral plaque was positively associated with the severity of the disease. There was no significant association among other parameters. Scoring systems, to determine the extraintestinal manifestation, should be standardized based on the scoring outcomes.
