Prediction System of Clinical Endpoint Events for Chronic Hepatitis B Patients

A total of 2000 chronic hepatitis B (CHB) patients with liver biopsy performed at least 1 year after antiviral therapy are enrolled. All the patients will receive original antiviral treatment for the following 10 years. Patients will be assessed at baseline and at every six months for blood count, liver function test, alpha fetoprotein (AFP), prothrombin time, liver ultrasonography, liver stiffness measurement (LSM), Hepatitis B virus (HBV) DNA and HBV serological markers. HBV-related endpoint events, including cirrhosis decompensations (ascites, esophageal variceal bleeding and hepatic encephalopathy), hepatocellular carcinoma (HCC), liver transplantation and liver-related death, will be collected during follow-up.

No.

Eligibility Criteria:

Exclusion Criteria:

* Patients with decompensated cirrhosis (including ascites, hepatic encephalopathy, esophageal varices bleeding, hepatorenal syndrome, spontaneous bacterial peritonitis, or other complications of decompensated cirrhosis), hepatocellular carcinoma, or liver transplantation before liver biopsy;

* Patients with malignant lesion on liver image;
* Patients with other uncured malignant tumors, exclude who were cured;
* Patients with severe heart, lung, kidney, brain, blood, neuropsychiatric or other organs diseases;
* Pregnant or lactating women;
* Patients with any other reasons not suitable for the study.
