Background and Aims: Viral hepatitis is a global health problem with a high mortality rate. Recently, a new Flavi-like virus, provisionally named hepatitis G virus (HGV), has been described. HGV does not induce an immune response that is consistently detectable by using recombinant proteins from prokaryotic expression, therefore studies have been conducted by using polymerase chain reaction (...

 ABSTRACT Background: Hepatitis B virus (HBV) infection in patients who lack detectable hepatitis B surface antigen (HBsAg) is called occult hepatitis B infection. Such infections have been frequently identified in patients with chronic hepatitis Cliver disease, but their prevalence is not known. Methods: 207 patients with chronic hepatitis C who were HCV -RNA and antiHCV positive were stu...

conclusions this study found that gbv-c infection has a high frequency among injecting drug users with hiv/hcv coinfection and hcv mono-infection in yunnan, china. in patients with chronic hepatitis c and hiv coinfection, gbv-c rna was associated with significantly lower alt and ast levels, suggesting a beneficial effect of gbv-c infection on chronic hepatitis c. results gbv-c rna was identifie...

context several risk factors play the role in the development of hepatocellular carcinoma (hcc) from which chronic hepatitis b and c infections are the most important ones. dna integration of hepatitis viruses alters the function of critical genes promoting malignant transformation of virus-infected liver cells. evidence acquisition there are remarkable geographic differences in prevalence of c...
