Abstract
Objective: To analyze the polymorphisms of human leukocyte differentiation antigens Ⅰ and Ⅱ (HLA-A, B, DRB1) alleles and explore the association between HIV infection and HLA loci, for discovering the distribution of HLA loci in HIV-infected with different disease progression in different parts of Henan Province. Methods: A total of 48 cases of slow progressers and 80 typical progressers in Weishi County, Shangcai County, Xihua County and Xuchang City of Henan Province were studied, and compared with 380 healthy blood donors.For analyzing HLA-A, B, DRB1 alleles and comparing difference among the study subjects, the method of polymerase chain reaction-sequence special oligonucleotide (PCR-SSO) was used. Results: The association of HLA alleles and HIV infection showed that HLA-B*40∶02, HLA-DRB1*04∶05 was significantly more common in healthy people, while HLA-B*15∶18, B*44∶02, B*67∶01 and HLA-DRB1*14∶01 were present in HIV/AIDS.HLA-A*02∶06, HLA-B*13∶02, B*40∶06 in slow progressers were higher than typical progressers from the grouped study, and HLA-B*46∶01 only appeared in the typical progressers. Conclusion: HLA-B*15∶18, B*44∶02, B*67∶01, and HLA-DRB1*14∶01 may be associated with HIV susceptibility.HLA-A*02∶06, HLA-B*13∶02, and B*40∶06 may be associated with delayed disease progression in HIV-infected people, while HLA-B*46∶01 may be associated with accelerated disease progression.
