Relationship of circulating CD4+ T-lymphocytes and p24 antigenemia to the risk of developing AIDS in HIV-infected subjects with oral hairy leukoplakia.

To investigate the relationship of circulating CD4+ T-lymphocytes and p24 antigenemia to the development of AIDS in HIV-infected subjects with hairy leukoplakia ( HL), we have followed over eight years 173 HIV-positive patients, all asymptomatic at the start of the study, and compared those who developed HL (n=55) to those who did not (n=118). Both groups included injection drug users (IDUs), homosexual men, and hemophiliacs. At the time of their first visit, both HL+ and HL- patients had a normal value of CD4+ cells and a low frequency of p24 antigenemia. During the years of follow-up, patients in the HL+ group showed a greater reduction in CD4+ cells, a significant increase in p24 antigenemia, and a higher rate of progression to AIDS. Our study demonstrates that in HIV-positive patients, HL is associated with more compromised immunological parameters and a higher viral replication and that its appearance has a negative prognostic value in relation to AIDS progression.[1]
