Transmission of human immunodeficiency virus type 1 from a patient who developed AIDS to an elite suppressor.

ABSTRACT: Elite suppressors (ES) are untreated human immunodeficiency virus type 1 (HIV-1)-infected patients who maintain viral loads of <50 copies/ml. The mechanisms involved in this control of viral replication remain unclear. Prior studies suggested that these patients, as well as long-term nonprogressors, are infected with defective HIV-1 variants. Other reports have shown that the HLA-B*27 and -B*57 alleles are overrepresented in these patients, suggesting that host factors play a role in the control of viral replication. In order to distinguish between these hypotheses, we studied differences in viral isolates and immune responses of an HIV-1 transmission pair. While both patients are HLA-B*57 positive, the transmitter progressed to AIDS, whereas the recipient, who is also HLA-B*27 positive, i
