title: Reconstitution of hepatitis B virus (HBV)-specific T cell responses with treatment of human immunodeficiency virus/HBV coinfection.
abstract: Liver-related mortality is an increasing problem in human immunodeficiency virus (HIV)/hepatitis B virus (HBV)-coinfected patients receiving highly active antiretroviral therapy (HAART). In HIV-negative patients, HBV chronicity is associated with a reduction in specific T cell responses that can be partially restored by treatment with lamivudine. We studied 5 HIV/HBV-coinfected patients treated with HAART, either with or without addition of a drug with specific anti-HBV activity. Our data show that reconstitution of some HBV-specific T cell responses can also occur in HIV-positive patients after a reduction in HBV load. This potential to recover T cell responses, which has been thought to be critical for HBV control, provides support for the addition of anti-HBV therapy in the treatment of HIV/HBV-coinfected patients.
