Insights
The Korea hepatitis B cohort study tracked 2,799 individuals with chronic hepatitis B virus (HBV) infection. Effective antiviral therapy improved chronic hepatitis B management, informing future public health policies in the Republic of Korea.
Area of Science:
- Hepatology
- Epidemiology
- Public Health
Background:
- Chronic hepatitis B virus (HBV) infection poses a significant public health challenge in the Republic of Korea (ROK).
- Understanding the epidemiological characteristics and treatment outcomes of HBV is crucial for effective disease control.
Purpose of the Study:
- To analyze the epidemiological features of chronic hepatitis B in the ROK.
- To evaluate treatment outcomes and identify factors influencing disease progression.
- To provide evidence for HBV control strategies and national policy development.
Main Methods:
- A prospective observational cohort study involving adults (≥19 years) with chronic HBV infection.
- Data collection included antiviral treatment, treatment adherence, and liver-related outcomes (e.g., hepatocellular carcinoma).
- Longitudinal blood samples were collected from consenting participants over a 6- to 12-month interval.
Main Results:
- 2,799 participants' data were analyzed from 2015-2024.
- Epidemiological patterns aligned with existing trends in the ROK.
- Effective antiviral therapy was linked to improved management of chronic hepatitis B.
Conclusions:
- Continued monitoring of the cohort is essential for understanding long-term outcomes.
- Study findings will inform revisions of national clinical practice guidelines.
- Evidence generated will support the development of public health policies for HBV control in the ROK.
Objectives:
The Korea hepatitis B cohort study is a prospective cohort established to analyze the epidemiological characteristics and treatment outcomes of individuals with chronic hepatitis B virus (HBV) infection in the Republic of Korea (ROK). This study aims to provide evidence to support HBV control, prevention strategies, and national policy development.
Methods:
Adults aged ≥19 years with chronic hepatitis B were enrolled at five regional medical institutions across ROK. Additional blood samples were collected from participants who consented to biospecimens donation. This prospective observational study did not interfere with routine clinical care. Data on antiviral treatment, treatment continuation, and liver-related outcomes, including hepatocellular carcinoma, were collected.
Results:
Between 2015 and 2024, a total of 3,221 participants were enrolled in the study. After excluding 422 individuals who were lost to follow-up, clinical data from 2,799 participants were collected. On average, 4.2 longitudinal blood samples per participant were obtained at 6- to 12-month intervals. The cohort exhibited epidemiological patterns consistent with previously reported trends in the ROK. The use of effective antiviral therapy was associated with better management of chronic hepatitis B.
Conclusions:
The continuation of this study will enable systematic and efficient monitoring of the current status and long-term clinical outcomes of patients with chronic hepatitis B. These findings are expected to inform revisions of national clinical practice guidelines and support the development of public health policies in the ROK.
