title: Human herpesvirus 8 serological markers and viral load in patients with AIDS-associated Kaposi's sarcoma in Central African Republic.
abstract: Epidemic Kaposi's sarcoma (KS) is one of the most frequent types of cancer in several African countries; however, very few data are available on human herpesvirus 8 (HHV-8) markers in KS patients from Central Africa. In a series of 36 AIDS-KS cases from Central African Republic, we showed, using a real-time PCR quantitative assay, the high frequency (82%) of detectable HHV-8 DNA in peripheral blood mononuclear cells (PBMCs). We also found that the level of antibodies directed against lytic or latent HHV-8 antigens is not correlated to the amount of HHV-8 viral load in the PBMCs, and finally, we demonstrated a much higher viral load in tumoral skin lesions (6.07 log copies/mug DNA) than in unaffected skin (2.93 log copies/mug DNA) or in PBMCs (2.55 log copies/mug DNA).
