Abstract:
Objective To investigate the association between nonalcoholic fatty liver disease (NAFLD) and metabolism or carotid intima-media thickness (CIMT) in Type 2 diabetic(T2DM). Methods According to the liver B-ultrasonography, a total of 321 T2DM patients were divided into two groups, with or without NAFLD. Metabolic indexes such as BMI, BP, blood glucose, blood lipid, uric acid ( UA ), insulin, C-peptipe,insulin resistance index(HOMA-IR) between the two groups were compared, and the relationships between alanine aminotransferase (ALT) and the above indexes were analyzed. Furthermore,the CIMT of the two groups were compared, and the relationships between NAFLD, ALT and CIMT were investigated by correlation and regression analysis. Results Compared with the group without NAFLD, the patients with NAFLD had higher level of BMI, triglyceride ( TG ), UA, fasting blood glucose ( FBG ), fasting insulin ( FIns ), fasting C peptide (FCP) ,HOMA-IR,and lower level of high density lipoprotein ( HDL-C ) significantly; BMI ( OR = 1.25, P ＜0. 001 ), TG ( OR = 1.74, P = 0. 008 ) and HOMA-IR ( OR = 2. 33, P = 0.010) were independent risk factors of NAFLD while H DL-C was independent protective factor; ALT was positively correlated with BMI (r = 0. 255, P ＜0. 001 ) ,TG(r =0. 156,P ＜0. 018) ,UA(r =0. 239,P ＜0. 001 ) ,FIns(r =0. 213,P =0. 001) ,FCP(r =0. 199,P ＜0. 003), HOMA-IR ( r = 0. 247, P ＜ 0. 001 ) and negatively correlated with HDL-C ( r = - 0. 199, P =0. 002) ,and BMI (β =0. 456,P =0. 048) ,UA (β =0. 021 ,P =0. 025) and HOMA-IR(β =3.634 ,P =0. 004)were independent associated facrors. The difference of CIMT between the two groups didn't reach statistical significance, while mutiple regression analysis revealed that ALT was independently associated with CIMT(β =0. 002,P = 0. 013). Conclusion T2DM patients with NAFLD show more serious disorder of metabolism and insulin resistance. ALT is an independent risk factor of CIMT in T2DM patients.
