Comparative prevalence of plasma human herpesvirus 8 DNA in sexual contact and intravenous injection routes of HIV transmission

Abstract

Detection of plasma human herpesvirus (HHV)-8 DNA correlates with antibodies to lytic HHV-8 antigens, being predictive of Kaposi's sarcoma in HIV-infected patients. We show that the prevalence of plasma HHV-8 DNA was 10.6% for HIV infection through sexual contact and 7.1% for HIV infection through intravenous injection. In addition, the prevalence of plasma HHV-8 DNA was significantly associated with male gender (9.4%) and HIV viral load below 1000 copies mL(-1) (12.1%), but not age or CD4 cell count in HIV-infected patients. The study suggested that detection of plasma HHV-8 DNA could be important for monitoring replicating HHV-8 in HIV-infected patients, and may have use as a marker for the diagnosis of HHV-8 infection in blood-borne transmission.
