Exocrine pancreas functions in children with type 1 diabetes mellitus

Abstract

Background and study aimWe evaluated exocrine pancreas functions using a noninvasive indicator in a case–control study conducted on children and adolescents diagnosed with type 1 diabetes mellitus. Patients and methodsSixty-seven patients who participated in a summer camp were enrolled in this study. Nineteen healthy children in the same age group were assigned to the control group. Fecal pancreatic elastase was assayed using the enzyme-linked immunosorbent assay technique. Values higher than 200 µg/g were considered an indication of sufficient exocrine pancreatic functioning, values between 100 µg/g and 200 µg/g were considered mild exocrine pancreatic insufficiency, and values below 100 µg/g were considered severe exocrine pancreatic insufficiency. ResultsThe mean concentration of fecal elastase was 158.38 ± 59.67 µg/g. The patients were assigned to three groups according to these values. Thirteen patients (22%) had sufficient fecal elastase levels, whereas 36 patients (62%) had mildly insufficient levels, and nine patients (16%) had severely insufficient fecal elastase concentrations. The levels of fecal elastase, amylase, lipase, and zinc were significantly different between the patients and controls (p < 0.001). Only the duration of diabetes was significantly different between patients with different severities of exocrine pancreatic insufficiency (p = 0.037). Additionally, the group with severe pancreatic insufficiency had more frequent hypoglycemic attacks. ConclusionExocrine pancreatic insufficiency may develop in children with diabetes, and hypoglycemia attacks are observed more frequently depending on the severity of pancreatic insufficiency.
