Abstract
The relationship between cerebrospinal fluid (CSF) markers of HIV infection and the spectrum of neurological manifestations were studied in 15 AIDS patients (13 with and 2 without confirmed neurological disorders). We demonstrated the presence of intrathecally synthesized anti-HIV antibodies. Antibodies to HIV envelope proteins were present in all patients but those to HIV core proteins in 9/13 cases only. HIV antigen and HIV p24 antigen were present in 6/14 and 4/12 cases respectively. HIV was not isolated from 6 samples of CSF. We have demonstrated that CSF markers of HIV infection were present in all AIDS patients, with or without neurological manifestations. Moreover HIV p24 antigen seems to be a very reliable marker of HIV infection.
Sommario
Gli AA. riportano i risultati di uno studio effettuato sul liquido cefalorachidiano (LCR) di 15 pazienti con AIDS (13 con e 2 senza, manifestazioni neurologiche) al fine di correlare i segni liquorali di infezione da HIV con il quadro neurologico.
È stata evidenziata in tutti i pazienti la presenza di anticorpi anti-HIV di sintesi intratecale. In particolare in tutti i pazienti sono stati dimostrati anticorpi diretti contro le proteine dell'envelope dell'HIV, mentre anticorpi anti-core sono stati riscontrati solo in 9 dei 13 casi esaminati. L'antigene dell'HIV e l'antigene p24 dello stesso virus sono, stati evidenziati rispettivamente in 6 su 14 e in 4 su 12 casi. L'HIV, ricercato in coltura cellulare nel LCR di 6 pazienti, non è stato isolato da nessun campione.
Gli AA. concludono che segni di infezione da HIV sono presenti nel LCR di pazienti con AIDS, indipendentemente dalla comparsa o meno di manifestazioni neurologiche. Infine, la presenza nel LCR dell'antigene p24 dell'HIV sembra costituire un importante segno di infezione del SNC da parte di tale virus.
