Prevalence of Pancreatic Exocrine Insufficiency among Patients with Diabetes Mellitus in India.

ABSTRACT

AIMS: We aimed to assess the prevalence of pancreatic exocrine insufficiency (PEI) in Indian patients with type 1 diabetes (T1D) or type 2 diabetes (T2D) using a unique diagnostic criterion. METHODS: This multicenter study included patients aged ≥18 years with diabetes for at least 5 years. The sociodemographic characteristics, lifestyle habits, and clinical characteristics of patients were assessed. Patients were administered the PEI questionnaire (PEI-Q), and fecal elastase-1 (FE) concentration was measured. Patients were diagnosed to have PEI if they satisfied any two of the following three criteria (a) a PEI-Q total symptom score of ≥0.60; (b) presence of malnutrition using the European Society of Clinical Nutrition and Metabolism diagnostic criteria for malnutrition; or (c) FE concentration <100 µg/gm stool. RESULTS: This multicenter study included patients aged ≥18 years with diabetes for at least 5 years. The sociodemographic characteristics, lifestyle habits, and clinical characteristics of patients were assessed. Patients were administered the PEI questionnaire (PEI-Q), and fecal elastase-1 (FE) concentration was measured. Patients were diagnosed to have PEI if they satisfied any two of the following three criteria (a) a PEI-Q total symptom score of ≥0.60; (b) presence of malnutrition using the European Society of Clinical Nutrition and Metabolism diagnostic criteria for malnutrition; or (c) FE concentration <100 µg/gm stool. CONCLUSIONS: Pancreatic exocrine insufficiency (PEI) was found to be prevalent in nearly one-fourth of Indian patients with diabetes, using composite diagnostic criteria.
