Individualizing care of hepatitis B in older adults and Asians

Insights
Hepatitis B virus (HBV) infection disproportionately affects older adults and Asian populations, increasing their risk for chronic liver disease and cancer. Targeted preventive strategies are crucial for these vulnerable groups.
Area of Science:
- Hepatology
- Virology
- Public Health
Background:
- Hepatitis B virus (HBV) is a significant global health concern.
- Acute HBV infection often presents with mild, non-specific symptoms and is typically self-limiting.
Purpose of the Study:
- To examine the pathophysiology of HBV infection in specific populations.
- To identify risk factors and preventive measures for older adults and Asian populations.
Main Methods:
- Review of scientific literature.
- Analysis of current practice guidelines.
Main Results:
- Chronic HBV infection is defined by persistent Hepatitis B surface antigen (HBsAg) for over six months.
- Older adults and individuals of Asian descent face elevated risks of chronic HBV progression and liver damage.
Conclusions:
- Chronic HBV infection is a primary risk factor for hepatocellular carcinoma.
- Tailored preventive services are essential for high-risk populations, including older adults and Asian communities.
Purpose:
To review the pathophysiology of hepatitis B virus (HBV) as it relates to special groups such as older adults and Asian populations and to stratify preventive services relative to these particular populations.
Data Sources:
Selected scientific literature and practice guidelines.
Conclusions:
The HBV is one of the most common causes of viral hepatitis. Acute infection is mostly self-limiting with nonspecific symptoms. Chronic infection is characterized by persistent serum levels of Hepatitis B surface antigen (HBsAg) for more than six months.
Implications For Practice:
Chronic HBV is a major risk factor for hepatocellular carcinoma. Special populations, such as older adults with decreased immune response and Asians from places with high endemic HBV infection, are at particularly high risk for progression of HBV infection to chronic states and serious liver damage.
