Introduction
Human Leukocyte Antigens (HLA), also known as transplantation antigens, determine the immune response. We give a brief account of them, and of more complex immunology, to explain why HLA phenotype may be specifically important in HIV disease, as it is in other infectious diseases.1 Study requirements for investigating HLA-associated progression of HIV disease are illustrated with Scottish data; susceptibility to HIV infection is considered only briefly.
Systematic review of published and other diverse data on three HLA associations with HIV progression is attempted, and the difficulties illustrated, for: the ancestral phenotype HLA-A1, B8, DR3 (which is associated with a range of autoimmune diseases); the allele B35 (which is common in Africans, and has been implicated empirically in HIV progression); and B27 (because Ohno2 established a theoretical basis for its association with slow HIV progression, which McNeil et al.3 corroborated).
The systematic review suggests that major HLA effects on HIV progression
