Summary
Brief summary
Human immunodeficiency virus/Hepatitis B virus (HIV/HBV) co-infections are frequently
observed due to shared routes of transmission, with reported figures indicating 6-9% of
HIV-infected individuals in developed countries are chronically infected with HBV. HIV
infection impacts on the natural progression of HBV infection, increasing levels of HBV
replication and the risk of liver-associated mortality. Liver diseases associated with HBV
are affected by the antiviral drugs used for HIV infection (toxic side effects), the current
immune function in the patient, by improvements in the immune system brought about by control
of the HIV infection, and by the development of resistance to the antiviral agents used for
both the hepatitis B and the HIV infection. Tenofovir (TDF) is a newer antiviral drug that is
frequently used for HIV infection and is also highly active against hepatitis B; however it
is still unknown whether resistance to TDF will eventually develop and how this will affect
the long-term outcomes
