Abstract:
ObjectiveTo investigate the association of nonalcoholic fatty liver disease (NAFLD) with insulin resistance and dyslipidemia in patients with type 2 diabetes mellitus,and to analyze the risk factors.Methods A total of 200 patients with type 2 diabetes mellitus including 99 with NAFLD and 101 without NAFLD were recruited.Height,weight,waist circumference,hip circumference,liver enzymes,blood lipids,fasting and postprandial blood glucose,insulin,C-peptide,and HbA1C levels were detected.Body mass index ( BMI),waist-hip ratio( WHR),and improved insulin and C-peptide index(HOMA-C-peptide) were calculated and compared between two groups.ResultsCompared with non-NAFLD group,weight,BMI,waist circumference,hip circumference,alanine aminotransferase ( ALT),aspartate aminotransferase,triglyceride ( TG ),total cholesterol ( TC ),low density lipoprotein-cholesterol(LDL-C) were significantly higher in NAFLD group( all P<0.01 ),while age,duration,and high density lipoprotein-cholesterol were lower( all P<0.05 ).The incidence of combined hyperlipidemia,especially hypertriglyceridemia,was significantly higher in NAFLD group( P<0.01 ).Fasting and postprandial 1 h blood glucose [ ( 2.07 ±0.36 vs 1.83 ±0.43 ) mmol/L,( 14.04 ± 3.96 vs 12.59 ± 3.90 ) mmol/L ],fasting and postprandial 1 h Cpeptide [ (2.79± 1.15 vs 2.08±1.29 ) ng/ml,( 1.33 ±0.45 vs 1.12±0.54) ng/ml ],HbA1C [ (2.09±0.33 vs 1.96±0.28) % ],and HOMA-C-peptide index were significantly increased in NAFLD group ( P < 0.05 or P < 0.01 ).Logistic analysis showed that TG,BMI,and ALT were the major risk factors of NAFLD in type 2 diabetes mellitus( P<0.05 or P<0.01 ).ConclusionTriglyceridemia,obesity,and raised ALT level were significantly associated with an increased risk of NAFLD in patients with type 2 diabetes mellitus.
