 AB    OBJECTIVE: To determine the relative frequencies of HIV-1 p24 antigen
       and culture positivity in white and black patients. DESIGN: Volunteers
       in the US military's HIV natural history study were 46% white, 44%
       black, 7% Hispanic and 3% other. Focusing on the comparable groups of
       whites and blacks, a retrospective analysis was performed of the results
       of virologic assays collected over a 2-year period. METHODS: p24 antigen
       was quantitated in sera with and without immune complex dissociation
       (ICD); viral isolation was performed by coculture of peripheral blood
       mononuclear cells. RESULTS: Results of the two virologic assays were
       very similar in the two racial groups, both overall and after
       stratification by CD4 cell count. As reported previously, the
       concentration of serum immunoglobulin G was found to be greater in black
       than white subjects. In contrast to results with ICD, sera tested
       without ICD resulted in differing (higher) rates of antigenemia in
       whites than blacks (P = 0.002). CONCLUSIONS: The frequencies of p24
       antigen and culture positivity were found to be independent of race.
       Previously observed racial differences in antigen positivity were likely
       to be due to more extensive antibody binding in blacks than in whites.
