摘 要:目的分析河南部分地区HIV感染不同疾病进展人群的人类白细胞分化抗原Ⅰ、Ⅱ型分子(HLA—A、B、DRB1)等位基因多态性,探讨HIV感染与HLA位点的关联性,发现HIV感染不同疾病进展人群的HLA位点分布特征。方法本研究收集2016年6月至2017年6月河南尉氏县、上蔡县、西华县、许昌市四地区的48例HIV感染缓慢进展者和80例典型进展者为研究对象,同时以380名健康献血者为对照,采用PCR—SSO流式荧光微珠法对HLA—Ⅰ类(A和B)和Ⅱ类(DRB1)基因进行高分辨率分型检测。比较分析研究对象间HLA等位基因频率分布差异。结果HLA等位基因分布与HIV感染的关联分析显示,HLA—B*40:02,HLA-DRB1*04:05显著多见于健康人群,而HLAB*15:18、B*44:02、B*67:01和HLA—DRB1*14:01均出现HIV/AIDS中。HIV感染不同疾病进展人群比较发现,HLA—A*02:06、HLA-B*13:02、B*40:06在感染缓慢进展组分布高于典型进展组,HLA—B*46:01仅出现在典型进展组。结论HLA—B*15:18、B*44:02、B*67:01和HLA—DRB1*14:01位点可能与HIV感染易感性有关。HLA—A*02:06、HLA—B*13:02、B*40:06等位基因可能与延缓本地区HIV感染人群病程有关,而HLA—B*46:01可能与加速病程相关。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 assoeiation 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.
