About

It remains unknown whether antiviral therapy is beneficial for chronic hepatitis B (CHB) with normal or mild ALT.The investigators aim to evaluate the antiviral indications combining liver biopsy and clinical parameters,and further clarify the response indexes of clinical results such as virological, serological, biochemical and histological responses from a retrospective observational cohort study on antiviral therapy in HBeAg positive and negative patients with different ALT levels,especially when ALT lower 2 times upper limit of normal (ULN).

Full description

It is estimated that 400 million people worldwide are chronically infected with hepatitis B virus (HBV).Chronic hepatitis B (CHB) often leads to serious health conditions including decompensated liver cirrhosis and hepatocellular carcinoma (HCC). Therefore, the goal of chronic hepatitis B (CHB) therapy is to achieve sustained suppression of HBV replication and remission of liver disease.Clinical CHB management guidelines suggest recommend threshold for antiviral therapy when ALT was more than 2 times ULN.No antiviral drugs are recommended for patients with normal ALT or mildly elevated ALT unless they exhibit symptoms of advanced fibrosis or liver cirrhosis.But chronic HBV infections with normal or mild ALT levels may develop latently into CHB,even cirrhosis and hepatocellular carcinoma (HCC).The ALT level is easily influenced by many factors.Antiviral therapy may still be needed for some HBV patients with normal or mildly abnormal ALT levels. Therefore, the investigator's purpose is to evaluate of antiviral indications and therapeutic effect by liver biopsy and clinical trial parameters on chronic HBV infection with different ALT levels,especially when ALT lower 2 times upper limit of normal (ULN).
