Detection and analysis of HAV-HEV, HGV infection in patients with viral hepatitis / 中华肝脏病杂志

<p><b>OBJECTIVE</b>To study the simple infection and super/co-infection of HAV-HEV, HGV in patients with viral hepatitis.</p><p><b>METHODS</b>Using EIA method to detect anti-HAV IgM, HBV serum markers, anti-HCV IgM, anti-HDV IgM, anti-HEV IgM, anti-HGV IgM in viral hepatitis patients with different clinical types.</p><p><b>RESULTS</b>Seventy-three percent patients (154/210) had HBV infection markers, twenty-nine percent patients (61/210) had HAV infection marker, eight percent patients (17/210) had HCV, HDV infection markers, ten percent patients (21/210) had HEV infection and seven percent patients (15/210) had HGV infection. Only nine percent patients (20/210) had viral hepatitis serum markers negative. In all clinical types, sixty-one percent patients had only one type hepatitis virus infection, thirty-two percent patients had two types of hepatitis virus super/co-infection, six percent patients had three types of hepatitis virus super/co-infection. Super/co-infection often occurred in patients who had cirrhosis or hepatic failure.</p><p><b>CONCLUSION</b>HBV and HAV infection is very common in viral hepatitis patients, whereas HCV, HDV, HEV and HGV infection is relatively low; double super/co-infection of HAV-HEV, HGV frequently occurs in severe patients with viral hepatitis.</p>

Relationship between hepatitis G virus infection and hepatic failure / 中华肝脏病杂志

<p><b>OBJECTIVE</b>To study the pathogenic effect of hepatitis G virus (HGV) infection on hepatic failure.</p><p><b>METHODS</b>Using the RT-PCR and EIA techniques to detect HGV RNA and anti-HGV in sera of hepatic failure patients and compare them with their liver function and mortality rates.</p><p><b>RESULTS</b>There was no significant difference about the positive rates of HGV among acute hepatic failure, subacute hepatic failure and chronic hepatic failure groups (X(2)=2.54, P>0.05). The level of ALT in HGV-positive group was slightly lower than that in HGV-negative group. The concentration of bilirubin and globulin was higher in HGV-positive group than HGV-negative group, and the concentration of albumin in HGV-positive group was significantly lower than that in HGV-negative group (t=2.59, P<0.05). The mortality rate in HGV-positive group was significantly lower than that in HGV-negative group (X(2)=4.68, 0.01<P<0.05).</p><p><b>CONCLUSIONS</b>The virulence of HGV is mild, and the HGV infection does not aggravate hepatic failure.</p>
