Analysis of clinical features of hepatitis B virus/hepatitis C virus coinfected patients with different virological profiles

Objective To understand the clinical features of hepatitis B virus(HBV)/hepatitis C virus(HCV)coinfected patients with different virological profiles.Methods The clinical data of 186 patients with HBV/HCV coinfection from May 1999 to May 2010 in the Third Affiliated Hospital of Sun Yat-Sen University were analyzed retrospectively.The demographic data,epidemiological data,laboratory results and pathological index were analyzed.The statistical analysis was done using t test and chi square test.Results A total of 186 patients were divided into 4 groups:66(35.5%)in HBV DNA(-)/HCV RNA(-)group,8(4.3%)in HBV DNA(+)/HCV RNA(+)group,68(36.6%)in HBV DNA(+)/HCV RNA(-)group and 44(23.7%)in HBV DNA(-)/HCV RNA(+) group.The gender composition,complication incidence,transmission among drug users,alanine aminotransferase(ALT)level,total bilirubin(TBil)level,prothrombin activity(PTA)and hapatitis B e antigen(HBeAg)negative rate were all significantly different among four groups(F or x2=11.578,8.451,11.738,2.669,5.102,4.254 and 18.413,respectively;all P<0.05).In groups of HCV RNA(-)and HCV RNA(+),the proportions of patients infected through drug abuse were 49.3%and 23.1%,respectively(x2=9.987,P:0.002)and blood transfusion transmission were 29.9%and 46.2%,respectively(x2=4.412,P=0.036).When HBV DNA was negative,the median ALT levels in HCV RNA(-)and HCV RNA(+)patients were 177 U/L and 62 U/L,respectively(t=2.200,P<0.05),median TBil levels were 133 μmol/L and 20μmol/L,respectively (t=3.608,P<0.05)and PTA were 70.6%±27.7%and 83.3%±27.8%,respectively(t=-1.982,P<0.05).The HBeAg negative rate was not affected by HCV RNA levels(t=0.707,P>0.05).The HBeAg negative rate in HBV DNA(-)patients was 85.5%,which was higher than that in HBV DNA(+)patients(59.2%)(x2=16.393,P<0.05).Conclusions HBV DNA(+/-)/HCV RNA(-)profile were major components in HBV/HCV confection.HBV DNA level is related to disease progression and prognosis,but not relate to disease severity.Liver function damage and disease severity are aggravated with HCV RNA level decreases.HBV DNA level is related to HBeAg negative rate,while HCV RNA level is not related to HBeAg seroconversion rate.
