Unique Identifier : AIDSLINE ICA10/94369541 AB OBJECTIVE: To compare HIV viral RNA and P24 antigen as well as hemoral response to the infection among seroconverters (SC) who developed AIDS in less than 3 years with SC who did not develop AIDS. Seroprevalents (SP) with no CD4 decline in 7 years of follow up were also used as control. METHOD: 17 SCs who developed AIDS in 3 years, 42 SCs who were AIDS free and 56 SPs with no or minimal CD4 counts were selected from 4952 gay/bisexual men participating in Multicenter AIDS Cohort Study (MACS). HIV-1 P24 antigen and virion RNA as well as neoptrin, B-2 microglobulin, Interferon X, IgG, IgM, IgA and quantitative HIV-1 serology were performed in plasma. RESULTS: Levels of P24 antigen was significantly higher at first positive visit and visit closest to AIDS in SCs with AIDS less than 3 years. (0.02 and 0.004 respectively). Similarly titer of HIV RNA was 10(4.2) copies/ml and raised in rapid progressor as compared to 10(3.4) in non progressor and remained stable. Anti P24 and P17 was different in two groups (P = 0.02 and 0.0002 respectively). Data on neopterin, B-2, Ig's and Interferon show no or narrow correlation. CONCLUSION: The quantitation of viral antigen and RNA and anti-HIV antibodies serve as predictors of progression to disease stage among gay/bisexual men.
