Official title

Comparison of HIV-1 Epitopes That May be Recognized by HLA-B*3501 (PY) and -B*3503 (Px) Early After Seroconversion and After Development of AIDS

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This study will identify variations in the genome of the human immunodeficiency virus (HIV) early after infection and following the development of AIDS. It will analyze genetic material and clinical data from HIV-positive individuals to assess differences in viral epitopes between patients with two different gene alleles (alternative forms of a gene)-B\*3501 and B\*3503. (An epitope is a molecular region on the surface of an antigen capable of eliciting an immune response and of combining with the specific antibody produced by such a response.) HIV disease in people with the B\*3503 allele progresses significantly faster than it does in people with the B\*3501 allele. This study might provide information that is potentially useful in developing a successful HIV vaccine. Blood samples and clinical data for analysis will be obtained from the Johns Hopkins Bloomberg School of Public Health; the University of Pittsburgh; the John H. Stroger, Jr. Hospital of Cook County; the Howard Brown Health Center; Northwestern University; and the University of California at Los Angeles.
