Correlation between fecal (calprotectin and lactoferrin) results and colonoscopic findings in chronic diarrhea and recurrent abdominal pain in children and adolescents

Abstract

Background: Currently, endoscopy with biopsy is still considered the gold standard for the evaluation and diagnosis of mucosal inflammation and a number of scores exist to assess endoscopic activity in Crohn’s disease (CD) and ulcerative colitis (UC). Aim and objectives: the aim of the study was to determine the benefit of using both of fecal markers (calprotectin and lactoferrin) in patients presenting with chronic diarrhea and recurrent abdominal pain for differentiation between organic diseases, particularly inflammatory bowel disease (IBD) from non-organic disease, making colonoscope unnecessary. Subjects and methods: This prospective, observational and analytic study was carried out on 44 children who fulfilling the designed inclusion criteria. The study was carried out from Outpatient Clinic of Pediatric gastroenterology unit and from the Inpatient Units of the Pediatric department Faculty of Medicine, Al-Azhar University Hospitals (Al-Hussein & Sayed Galal Hospitals), as well as referral from other hospitals complaining of recurrent abdominal pain and chronic diarrhea from March 2020 to March 2022. Results: there was statistically significant difference between IBD group and functional abdominal pain group as regard fecal calprotectin with p-value≤ 0.001. There was statistically significant difference between IBD group and functional abdominal pain group as regard fecal lactoferrin with p-value≤ 0.001.
