ABSTRACT
Coinfection with hepatitis B virus (HBV) is common in the human immunodeficiency virus-1
(HIV)-infected patient because of shared modes of transmission. HBV does not appear
to alter HIV disease progression; however, HBV infection is more frequent and more
severe in the HIV-infected population, emphasizing the importance of preventing HBV
infection. The goal of anti-HBV therapy is prevention of cirrhosis because therapy
does not eradicate the hepatic reservoirs (cccDNA). The approved therapies-interferon-alfa,
lamivudine, and adefovir-each have a niche in the treatment of chronic hepatitis B
in the HIV-infected population, but none has been well-studied in this setting. As
new drugs currently in clinical trials become available, therapy for chronic hepatitis
B will enter the promising era of combination therapy.
