Abstract:
Objective To explore the influencing factors of hepatic steatosis in patients with chronic hepatitis B (CHB),and to provide a theoretical basis of hepatic steatosis prevention and control.Methods A total of 291 hospitalized CHB patients in affiliated Southeast Hospital of Xiamen University were enrolled and divided into two groups:132 CHB patients with hepatic steatosis as the case group and 159 CHB patients without hepatic steatosis as the control group.Conducted a case control study and compared the two groups in terms of body mass index (BMI),waist-to-hip ratio (WHR),fasting blood glucose (FBG),triglyceride (TG),total cholesterol (TC),aspartate aminotransferase (AST),gamma-glutamyl transpeptidase (γ-GT),hepatitis B e antigen (HBeAg),hepatitis B virus DNA (HBV DNA) by descriptive analysis and inferential statistics to analyze the association of these factors with hepatic steatosis in CHB patients.The histological characteristics of the liver were observed.The date analysis used rank sum test and t test.Results FBG,TG,TC,γ-GT,AST of the case group and the control group were (5.11±0.62) mmol/L,(1.81±0.89) mmol/L,(5.29±1.05) mmol/L,(65.04±53.89) U/L,(65.60±71.52) U/L and (4.94±1.89) mmol/L,(1.21±0.79) mmol/L,(4.25±1.58) mmol/L,(146.48±200.39) U/L,(165.35±180.57) U/L,respectively.The case group had significantly higher FBG,TG and TC than the control group (Z=3.607,4.039 and 4.197,respectively,all P＜0.01),while the control group had significantly higher γ-GT and AST (Z=2.672 and 3.020,respectively,both P＜0.01).BMI of the two groups were (26.89±2.78) kg/m2 and (21.17±2.96) kg/m2,respectively,higher in the case group (t=9.711,P＜0.01).WHR in male patients of two groups were 0.93±0.05 and 0.87 ± 0.06,respectively,higher in male patients of the case group (t=4.469,P＜0.01).Positive rate of HBeAg,HBV DNA between the case group and the control group hadn't significantly difference (x2 =0.334,2.960; both P＞0.05).The case group had more severe degree of hepatic steatosis than the control group (Z=-16.145,P＜0.01),while the inflammatory activity and fibrosis were more advanced in the control group (Z=-12.639,P＜0.01; Z=-11.242,P＜0.01,respectively).Conclusions BMI,WHR,FBG,TG and TC appear to be the influencing factors of CHB with hepatic steatosis.The hepatic steatosis in CHB patients is mainly caused by the changes of anthropometric indexes and metabolic factors rather than the effect of HBV.If effective measures are taken,hepatic steatosis in CHB patients can be effectively prevented.
