OBJECTIVE: To analyze the influence of hepatosteatosis on pancreatic P-cell function in type 2 diabetes mellitus (22DM).
METHODS: A total of 213 subjects with T2DM from Metabolic Disease Hospital, Tianjin Medical University from January 2013 to December 2013 were included in the study. Non-alcoholic fatty liver disease (NAFLD) was diagnosed with abdominal ultrasonography. Patients were divided into two groups: 22DM with NAFLD and 22DM without NAFLD. ALT, AST, gamma-glutamyltransferase, serum lipid, glycosylated hemoglobin A1c ( HbA1c), fructosamine, fasting glucose, insulin and 2 hours plasma glucose, insulin after 75g glucoseload were detected. The insulin resistance and P-cell function were assessed by HOMA-IR and HOMA-P.
RESULTS: Among the 213 22DM subjects, 51% (108 cases) were with NAFLD. The HOMA-IR [4.76(2.83,7.21) vs. 2.79 (1.76, 4.37),P <0.05] and HOMA-P [49.18 (37.78, 85.09) vs. 29.50 (18.09, 45.54), P < 0.05] were significantly higher in 22DM with NAFLD than those in 22DM alone. Within subjects with 22DM and NAFLD,the HOMA-IR [6.28 (2.87, 8.17) vs. 2.95 (2.07, 3.66)P <0. 05] and HOMA-P [59.18 (37.78, 85.09) vs. 30.59 (28.56, 34.49), P < 0.05] levels were higher in subjects with normal liver function than those with abnormal liver function.
CONCLUSIONS: T2DM patients with NAFLD have severer insulin resistance than those without NAFLD. The P-cell function of those patients was compensatory increased, which was decreased in subjects with abnormal liver function.
