ABSTRACT
Objective To explore the clinical characteristics of chronic hepatitis B patients with metabolic syndrome (MS).Methods A total of 127 patients with untreated chronic hepatitis B infection were recruited.The patients were divided into two groups according to the diagnosis of MS,with 45 in MS group and 82 in non-MS group.Age,gender,body mass index (BMI),waist-to-hip ratio (WHR),fasting blood glucose (FBG),triglyceride (TG),total cholesterol (TC),aspartate aminotransferase (AST),alanine aminotransferase (ALT),hepatitis B e antigen (HBeAg),hepatitis B virus deoxyribonucleic acid (HBV DNA) were compared between groups.Liver biopsy was performed in 94 patients,including 31 in MS group and 63 in non-MS group,to compare the histological characteristics of liver between two groups.A chi-square test and t test were used for the data analysis.Results BMI,WHR,TG,TC,and FBG results of patients in MS group and nonMS group were (28.88±3.00) kg/m2,0.93±0.03,(2.77±0.17) mmol/L,(6.51±0.95) mmol/L,(6.67±0.45) mmol/L,and (24.64± 2.21) kg/m2,0.91±0.04,(1.50±0.65) mmol/L,(4.38±0.71) mmol/L,(4.91±0.92) mmol/L,respectively.Patients in MS group had higher BMI,WHR,FBG,TG and TC compared with those in non-MS group (t=9.109,3.245,2.642,3.762 and 2.586,respectively; all P＜0.05).No statistical significant differences were found in age,ALT or AST between two groups (t=2.224,0.703 and 0.141,respectively; all P＞0.05).Neither any statistical difference was found in gender,the positive rate of HBeAg and HBV DNA between two groups (x2 =1.662,0.037 and 0.944,respectively; all P＞0.05).In inflammation activity comparison,the result of liver biopsy showed that 48.39 ％ (15/31) were classified as G0-G1 and 51.61％(16/31) as G2-G4 in MS group,and those in non MS group were 49.21％(31/63) and 50.79％(32/63),respectively.No statistical significance was reached (x2 =0.006,P＞0.05).In fibrosis stage comparison,patients in MS group classifies as S0-S1 and S2-S4 were 32.26％ (10/31) and 67.74％(21/31),respectively,and those in non-MS group were 60.32％ (38/63)and 39.68％ (25/63),respectively.The liver fibrosis in MS group was significantly more severe than that in non-MS group (x2 =6.546,P＜0.05).Conclusions The CHB patients with MS have higher BMI,WHR,FBG,TG and TC.The presence of MS may promote the progress of liver fibrosis in CHB patients.
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.
