简要总结
According to the World Health Organization about 1,400,000 deaths reported annually, are related to chronic liver disease. Chronic liver disease is very prevalent in South Korea, placing a large economic burden nationwide. Subsequently, an effective and systematized approach to managing chronic hepatitis is imperative in Korea.
The natural history of chronic liver disease differs greatly according to race and ethnicity. However, there is scarcity of epidemic data on chronic hepatitis based on Korean patients. Therefore, the investigators plan to establish a prospective multicenter cohort for chronic hepatitis B based on Korean patients that may be utilized for various future clinical studies on chronic hepatitis B in Korea, and thereby serve as a basis for the establishment and distribution of clinical guidelines for Korean patients with chronic hepatitis B, as part of a nationwide project supported by the Centers for Disease Control (CDC), Korea.
The investigators plan to collect more than 2,000 cases per year with 6 months of regular follow-up interval as have been advised by the CDC during 10 years of the study period (from Sep. 2015) from 5 tertiary hospitals located in Korea. The investigators plan to register available cases from those who are available to agree to give written informed consent and provide their blood samples to participate in this study prospectively, according to the inclusion and exclusion criteria.

研究组 & 干预措施
Korean chronic hepatitis B patients cohort
Korean patients with chronic hepatitis B with or without antiviral therapy on a regular follow-up in tertially medical institution
干预措施: Discontinuation of antiviral treatment in chronic hepatitis B cohort patients (Drug)
结局指标
主要结局
Development of liver cirrhosis, decompensation or liver cancer
时间窗: Time of registration of patient to cohort complement (10 years)
This study aims for the establishment of chronic hepatitis B cohort and has no other primary end point other than the registration of the patient. (For Time-to-Event outcome measures, the development of events including HCC, ascitic decompensation, variceal bleeding, hepatic encephalopathy, transplantation, and death will be followed up to 10 years after enrollment. Time to the development of each kind of event will be calculated from the date of enrollment and the respective date of event development.) Safety issue: No
次要结局
- Safety and efficacy for patients with or without antiviral therapy(Time of registration of patient to cohort complement (10 years))
