We compared the prevalence of HIV p24 antigenemia in black and white US patients with HIV infection. The prevalence of HIV antigenemia increased with severity of HIV disease (P < 0.001). In all clinical categories, whites were more likely to be HIV-antigenemic than blacks (overall prevalence 38 versus 18%; P < 0.01). Anti-p24 antibodies were detected in a higher proportion of blacks (84%) than whites (65%; P = 0.02). Blacks had significantly higher total serum immunoglobulin levels than whites (median 3.8 versus 3.2 mg/dl; P < 0.00001). Racial differences in HIV antigen expression may result from differences in humoral response to HIV infection. These differences should be considered when HIV antigen is used as a surrogate marker in clinical trials.
