Selecting appropriate management strategies for chronic hepatitis B: who to treat.
BACKGROUND
Hepatitis B virus (HBV) infection is a significant problem. In the United States estimates indicate that 0.3% of the population (1.25 million individuals) have chronic hepatitis B infection.


METHODS
Review of published practice guidelines and literature on management of hepatitis B to determine: 1) Which persons in Western populations are at the highest risk for HBV infection and should be screened for HBV seromarkers to identify those who are chronically infected and those who need to be protected with hepatitis B vaccine; 2) The importance of regular monitoring in persons with chronic hepatitis B, the frequency of monitoring, and which tests should be performed; 3) How to identify the patients who are appropriate candidates for antiviral therapy.


RESULTS
Recommendations for screening, diagnosis, monitoring, and treatment of chronic HBV infection are reviewed. Important differences are discussed between the Practice Guidelines for chronic hepatitis B developed by the American Association for the Study of Liver Diseases (AASLD), the European Association for the Study of the Liver (EASL), and the Asian Pacific Association for the Study of the Liver (APASL). In addition, this article reviews which patients who are no covered by these Guidelines might be candidates for antiviral therapy.


CONCLUSIONS
Established practice guidelines provide direction to providers for the diagnosis and management of chronic HBV infection to reduce the risk of serious sequelae. However, not all patients with chronic hepatitis B are identified, and many of those who are diagnosed do not receive adequate management and follow-up.
