Abstract:
Objective:To investigate the association of surrogate indexes of insulin resistance with the risk of nonalcoholic fatty liver disease(NAFLD)and advanced liver fibrosis in newly diagnosed patients with type 2 mellitus.Methods:A total of 429 newly diagnosed type 2 diabetic patients hospitalized in the Department of Endocrinology and Metabolism, Shanghai Ninth People′s Hospital, Shanghai Jiao Tong University School of Medicine from June 2018 to June 2020 were included. The patients were divided into NAFLD group( n=263)and non-NAFLD group( n=166)according to the results of abdominal ultrasound, NAFLD patients were divided into advanced liver fibrosis group( n=33)and non-advanced liver fibrosis group( n=230)according to the NAFLD fibrosis score(NFS). The correlation of the triglyceride/high density lipoprotein-cholesterol ratio(TG/HDL-C), triglyceride glucose index(TyG), visceral adiposity index(VAI), triglyceride glucose-body mass index(TyG-BMI), homeostasis model assessment of insulin resistance index(HOMA-IR)with NAFLD and the occurrence of advanced liver fibrosis were analyzed. Results:The prevalence of NAFLD in newly diagnosed type 2 diabetic patients was 61.3%, and the prevalence of advanced liver fibrosis was 12.5%. After adjusting the potential confounders, multivariate logistic regression analysis showed that TG/HDL-C, TyG, VAI, TyG-BMI, and HOMA-IR were independently and positively correlated with NAFLD, and only TyG-BMI was independently and positively correlated with advanced liver fibrosis( OR=1.021, 95% CI 1.009-1.034, P<0.01). The receiver operating characteristic analysis showed that the area under the curue of TyG-BMI was more than those of TG/HDL-C, TyG, VAI and HOMA-IR for predicting the occurrence of NAFLD in newly diagnosed type 2 diabetic patients(0.83 vs 0.73, 0.74, 0.73, 0.67, P<0.01), but had no predictive value for advanced liver fibrosis. Conclusion:TyG-BMI is superior to TG/HDL-C, TyG, VAI and HOMA-IR for predicting the occurrence of NAFLD in newly diagnosed type 2 diabetic patients, and it is also an independent risk factor for advanced liver fibrosis.
