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).
流行性卡波西肉瘤（KS）是几个非洲国家最常见的癌症类型之一；然而，关于中非KS患者中人类疱疹病毒8型（HHV-8）标志物的数据非常少。在一系列来自中非共和国的36例艾滋病相关KS病例中，我们使用实时PCR定量检测方法显示，外周血单个核细胞（PBMC）中可检测到HHV-8 DNA的频率很高（82%）。我们还发现，针对HHV-8裂解或潜伏抗原的抗体水平与PBMC中HHV-8病毒载量无关，最后，我们证明肿瘤皮肤病变中的病毒载量（6.07 log拷贝/μg DNA）比未受影响的皮肤（2.93 log拷贝/μg DNA）或PBMC（2.55 log拷贝/μg DNA）高得多。
