Low prevalence of exocrine pancreatic insufficiency in patients with diabetes mellitus

Abstract

IntroductionExocrine pancreatic insufficiency (EPI) can occur in patients with diabetes mellitus (DM). Incidence of EPI and its clinical significance remain poorly defined. The aim of our study was to determine whether exocrine pancreatic function is impaired in patients with DM. Patients and methodsOne hundred and fifty consecutive patients, mean age 59.0 (±12.0 years), with DM lasting at least 5 years were included in the study. We included 50 patients with type 1 DM (DM1), 50 insulin-treated patients DM type 2 (DM2-insulin) and 50 non-insulin treated patients with DM type 2 (DM2 no-insulin). Diagnosis of DM was established from health records, lasting 15.0 ± 9.9 years on average. EPI was diagnosed with a fecal elastase-1 concentration (FE1) of less than 200 μg/g (ELISA). ResultsFE1 was reduced in 8 (5.4%) patients: mildly reduced (100–200 μg/g) in 4 patients (2.7%) and markedly reduced (<100 μg/g) in 4 patients (2.7%). Frequency of EPI was 3 in DM1, 5 in DM2(insulin) and none in DM2 (no-insulin) groups. ConclusionsEPI in DM occurred less frequently than in previous studies, probably due to our strict exclusion criteria (age, alcohol intake).
