Prevalence of Exocrine Pancreatic Dysfunction Based on Direct Function Testing in Pediatric Inflammatory Bowel Disease
JOURNAL OF PEDIATRIC GASTROENTEROLOGY AND NUTRITION(2023)
Abstract
Objectives:Patients with inflammatory bowel disease (IBD) frequently have extraintestinal manifestations. The goal of this pilot study was to assess exocrine pancreatic function in cases with suspicion for or an established diagnosis of IBD. Methods:Direct stimulated endoscopic pancreatic function test (ePFT) was performed in 74 children with IBD, in both newly diagnosed and established cases. Demographic, clinical, and laboratory parameters were entered into a database and analyzed. Results:Among the 74 children, 49 were newly diagnosed and 25 had an established diagnosis of IBD. A majority had the diagnosis of Crohn disease (CD) (n = 48; 32 new and 16 established cases) with male predominance (64.6%). Altogether, 42 (56.7%) children had either generalized or partial exocrine pancreatic insufficiency (EPI). Twenty-four of the 48 CD children (50%) had abnormal ePFT. In those with ulcerative colitis (UC), 18 of the 26 (62.9%) had abnormal ePFT. The highest abnormality rate was in lipase enzyme activity. Weight z scores were significantly lower in those with abnormal ePFT (Crohn cases: P = 0.008; UC cases: P = 0.046). Peak protein concentration in collected pancreatic fluid was significantly lower in children with CD who had abnormal ePFT (P = 0.013). Conclusions:This pilot study revealed a relatively high prevalence of EPI in children with IBD through use of ePFT. EPI can result in maldigestion, with decreased capacity to digest fat. Further prospective studies are needed to assess need and efficacy of pancreatic enzyme replacement therapy in children with IBD and abnormal ePFT.
