Introduction: Cytomegalovirus retinitis is one of the ocular manifestations of AIDS. The objective of the present study was to determine possible associations of class I and II HLA antigens and alleles in patients with AIDS and cytomegalovirus retinitis (CMV-R) with and without macular involvement. Method: The study population consisted of 22 patients with AIDS and CMV-R with macular involvement (Group I), 19 patients with AIDS and CMV-R without macular involvement (Group II), and 202 individuals with negative serology for human immunodeficiency virus (Group III-control). Class I HLA antigens were typed by classical serology. Class II alleles were identified using sequence-specific oligonucleotide primers hybridized with amplified DNA. Results: HLA-DRB1*14 and HLA-DRB1*10 specificities were more frequent among patients with macular involvement, possibly indicating greater susceptibility to this condition. In contrast, the HLA-B35 antigen may be associated with protection against macular involvement since it was significantly more frequent among patients without this involvement. Conclusions: The HLA-DRB1*14 and HLA-DRB1*10 alleles may favor the development of CMV-R with macular involvement, whereas the HLA-B35 subtype may be associated with protection against macular involvement.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
