在成人和儿童获得性免疫缺陷综合征(艾滋病)患者中,脑脊液(CSF)中存在人类免疫缺陷病毒(HIV)抗原与进行性脑病有关。7例艾滋病进行性脑病患者中6例脑脊液中检测到HIV抗原。相比之下,18例无进展性脑病的HIV抗体血清阳性患者中仅1例在脑脊液中检测到HIV抗原,8例无临床症状的实验感染黑猩猩中0例在脑脊液中检测到游离或络合的HIV抗原。在大多数艾滋病患者(9/12)或有艾滋病风险的患者(8/13)以及实验感染的黑猩猩中,证明了血脑屏障内hiv特异性抗体的合成,表明大脑中hiv特异性b细胞的反应性没有明显的神经症状。在11例HIV感染患者中,有6例在中枢神经系统合成的抗体直接针对HIV包膜蛋白。活跃的病毒表达似乎对于与HIV感染相关的免疫缺陷和进行性脑病都是必要的。
The presence of human immunodeficiency virus (HIV) antigens in cerebrospinal fluid (CSF) was associated with progressive encephalopathy in adult and pediatric patients with acquired immunodeficiency syndrome (AIDS). HIV antigen was detected in CSF from 6 of 7 AIDS patients with progressive encephalopathy. By contrast, HIV antigen, whether free or complexed, was detected in CSF from only 1 of 18 HIV antibody seropositive patients without progressive encephalopathy and from 0 of 8 experimentally infected chimpanzees without clinical signs. Intra-blood-brain barrier synthesis of HIV-specific antibody was demonstrated in the majority of patients with AIDS (9/12) or at risk for AIDS (8/13) as well as in the experimentally infected chimpanzees, indicating HIV-specific B-cell reactivity in the brain without apparent neurological signs. In 6 of 11 patients with HIV infection, antibodies synthesized in the central nervous system were directed against HIV envelope proteins. Active viral expression appears to be necessary for both the immunodeficiency and progressive encephalopathy associated with HIV infection.
