Prediction System of Clinical Endpoint Events for Chronic Hepatitis B Patients

Study Overview
=================
Brief Summary
-----------------
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.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| HBV-related clinical endpoint events, including liver decompensations (ascites, esophageal variceal bleeding and hepatic encephalopathy), HCC, liver transplantation and liver-related death | Incidence of HBV-related clinical endpoint events during follow-ups | 1 to 10 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Predicted probability of HBV-related clinical endpoint events | The predicted probability is measured by histological prediction model or non-invasive prediction model | 1 to 10 years | 
| Predicted probability of HBV-induced fibrosis/cirrhosis regression | The predicted probability is measured by histological prediction model or non-invasive prediction model | 1 to 10 years | 
| Percentage of HBV-induced liver fibrosis/cirrhosis regression | Liver fibrosis regression was defined as decrease >= 1 point by Ishak fibrosis scoring system (range from 0 to 6, higher values represent a worse outcome) or Predominantly Regressive in P-I-R ( predominantly progressive, indeterminate and predominately regressive) score | 1 to 10 years |
