Epidemiology and Prevention of HIV and Viral Hepatitis Co-infections
Hepatitis B virus (HBV) and human immunodeficiency virus (HIV) are bloodborne viruses transmitted primarily through sexual contact and injection-drug use. Because of these shared modes of transmission, a high proportion of adults at risk for HIV infection are also at risk for HBV infection. HIV-positive persons who become infected with HBV are at increased risk for developing chronic HBV infection . Persons who are coinfected with HIV and HBV can also have serious medical complications and are at increased risk for liver-related morbidity and mortality [2-4]. To prevent HBV infection in HIV-infected persons, the Advisory Committee on Immunization Practices (ACIP) recommends universal hepatitis B vaccination for all susceptible persons infected with HIV . The first vaccine dose may be administered immediately after collection of blood for prevaccination serologic testing , and regardless of CD4+ lymphocyte cell count . To confirm adequate immune response, post-vaccination serologic testing for protective concentrations of antibodies to hepatitis B surface antigen should be conducted 1–2 months after completion of the hepatitis B vaccine series .
In 2009, approximately 21% of HIV-infected adults who were tested for past or present HCV infection tested positive, although coinfection prevalence varies substantially according to HIV-infected risk group (e.g., men who have sex with men [MSM], high-risk heterosexuals, and persons who inject drugs) [7-9]. As HCV is a bloodborne virus transmitted through direct contact with the blood of an infected person, coinfection with HIV and HCV is common (62–80%) among HIV-infected injection-drug users [8-10]. Although transmission via injection drug use remains the most common mode of HCV acquisition in the United States , sexual transmission is an important mode of acquisition among HIV-infected MSM with risk factors, including those who participate in unprotected anal intercourse, use sex toys, and use non-injection drugs . HCV is one of the primary causes of chronic liver disease in the United States, and HCV-related liver injury progresses more rapidly among persons coinfected with HIV [11-15]. HCV infection may also effect the management of HIV infection [6, 15, 16]. Guidelines recommend that all HIV-infected persons be screened for HCV infection and that persons with increased risk be retested annually [6, 15, 16].
