HIV and hepatitis C coinfection.
Coinfection with HIV and the hepatitis C virus (HCV) or hepatitis B virus (HBV) is a growing public health concern. Because the diseases are spread in similar ways--notably through shared use of needles to inject drugs and sexual activity--many people are coinfected with HIV and HCV, HIV and HBV, or even all three viruses. Hepatitis C and hepatitis B are viral infections of the liver; over time they can lead to serious consequences including liver cirrhosis and liver cancer. Most studies show that HIV infection leads to more aggressive hepatitis C or hepatitis B and a higher risk of liver damage. Studies of how HCV and HBV affect HIV disease are less clear. Most research shows that HCV does not accelerate HIV disease progression, but HIV/HCV coinfection may impair immune system recovery after starting antiretroviral therapy. Coinfection can complicate treatment. People with liver damage due to chronic hepatitis are more likely to experience hepatotoxicity (liver toxicity) related to anti-HIV drugs. In addition, drugs used to treat HIV and hepatitis can interact and side effects may be exacerbated. Most experts recommend that HIV should be controlled first before a person begins HCV treatment. With careful management, most people with HIV/HCV or HIV/HBV coinfection can be successfully treated for both diseases. In fact, several recent studies suggest that HIV/HCV-coinfected people with well-controlled HIV disease and relatively high CD4 cell counts may do as well as those with HCV alone.
