Summary
Chronic hepatitis B virus (HBV) infection is a significant health issue in Malaysia, disproportionately affecting Chinese males and leading to liver cancer (HCC). Understanding HBV prevalence and risk factors is crucial for public health strategies.
Area of Science:
- Hepatology
- Virology
- Public Health
Background:
- Chronic hepatitis B virus (HBV) infection is a major global health concern, particularly in East and South-East Asia.
- Malaysia faces a significant HBV burden, with carrier rates varying by ethnicity and a male predominance.
Purpose of the Study:
- To investigate the prevalence of chronic HBV infection and its associated risk factors in Malaysia.
- To determine the serological profile of HBV carriers and the incidence of HBV-associated hepatocellular carcinoma (HCC).
Main Methods:
- Serological studies were conducted on adult chronic HBV carriers in Malaysia.
- Data on ethnicity, gender, HBe antigenemia, HBV DNA status, and HCC incidence were analyzed.
Main Results:
- HBV carrier rates varied among ethnic groups (Chinese > Malays > Indians) and showed a male preponderance.
- HBe antigenemia was observed in 35% of carriers, decreasing with age; HBV DNA status correlated with HBe status.
- Hepatocellular carcinoma (HCC) is the third most common cancer in Malaysia, with 80% of cases linked to HBV, predominantly in Chinese males.
Conclusions:
- Chronic HBV infection and its complication, HCC, represent a substantial public health challenge in Malaysia.
- Ethnic and gender disparities in HBV prevalence and HCC risk highlight the need for targeted prevention and management strategies.
