Abstract:
ObjectiveTo explore the relationship between serum markers and liver fat content predicted by hepatorenal ratio in type 2 diabetic mellitus (T2DM) patients.Methods A total of 120 T2DM patients were recruited from January 2011 to September 2012 in the Affi liated Hospital of Qingdao University. The sagittal liver-right kidney diagrams of the patients were obtained by two-dimensional ultrasonic examination, and the hepatorenal ratio were analyzed by NIHimage. Then, the related serum markers were tested 24 hours later. The relationship between hepatorenal ratio and serum markers was analyzed by Spearman rank correlation on the patients of T2DM. Then, the affective factors on the hepatorenal ratio were analysed by multivariate linear regression analysis, with hepatorenal ratio as dependent variable, and the concentration of triglyceride (TG,X1) , total cholesterol (TC,X2), high density lipoprotein cholesterol (HDL-C,X3), low density lipoprotein cholesterol (LDL-C,X4), alanine aminotransferase (ALT,X5), aspartateaminotransferase (AST,X6), glutamyltransferase (γ-GT,X7) , and alkaline phosphatase (ALP,X8) as independent variables. The receiver operating characteristic curve (ROC) was drawn to diagnose the point of the hepatorenal ratio when the TG began to increase (>1.92 mmol/L).Results There was positive correlation between hepatorenal ratio and TG, AST, ALT,γ-GT (r=0.420,P=0.000;r=0.383,P=0.000;r=0.309,P=0.001;r=0.253,P=0.005), while no correlation between hepatorenal ratio and glycosylated hemoglobin, TC, HDL-C, LDL-C, ALP or blood uric acid (BUA) (r=0.0.067,P=0.368;r=0.145,P=0.115;r=?-0.148,P=0.106;r=0.002,P=0.986;r=0.160,P=0.081;r=0.064,P=0.489) were found; the linear regression analysis showed that TG level (X1) was the only markers which had correlation with hepatorenal ratio in the T2MD patients with the regression equation ofY=1.245+0.062X. The ROC curve analysis showed that the optimal cutoff value for hepatorenal ratio to in diagnosinge increased TG (>1.92 mmol/L) was 1.236 in T2DM patients, and the area under the curve was 0.677. The sensitivity and specifi city were 86.7% and 45.3% respectively. Conclusions Hepatorenal ratio can be a reliable indicator to predict liver fat content, which has correlation with TG, ALT, AST andγ-GT. The increased TG level can refl ect the increasing fat content in the liver, and TG begin to increase when the hepatorenal ratio reach 1.236.
