东莞市HIV-1流行株pol基因序列特征分析
Sequence analysis of pol gene of HIV-1 strain in Dongguan
摘要
Abstract
Objective To investigate the epidemiological characteristics of human immunodeficiency virus type 1(HIV-1)and the subtypes distribution among HIV-1-infected individuals in Dongguan.Method From January 2019 to January 2021,284 HIV-1 infected patients who had received antiviral treatment in Dongguan were selected,and was collected their epidemiological information.The viral RNA of HIV-1 was extracted from plasma.The pol gene was amplified by nested polymerase chain reaction.and gene sequence analysis was performed using biological software such as LaserGene,HIV BLAST,and MEGA 6.0.Result A total of 284 samples were collected in this study and finally successfully obtained 269 HIV-1 pol gene sequences.Among the 269 samples,86.2%(232/269)were male,61.3%(165/269)were younger than 40 years old,52.4%(141/269)were unmarried,and 49.4%(133/269)were heterosexual and 47.2%(127/269)were homosexual.Of the 269 pol gene sequences,eight genetic subtypes were identified:131(48.7%)CRF07_BC,59(21.9%)CRF01_AE,38(14.1%)CRF55_01B,19(7.1%)subtype B,12(4.5%)CRF08_BC,and 10(3.7%)other subtypes.Among 133 patients with heterosexual transmission,the predominant subtypes were 59(44.4%)CRF07_BC,32(24.1%)CRF01_AE,and 15(11.3%)CRF55_01B,and among 127 patients with homosexual transmission,the predominant subtypes were 65(51.2%)CRF07_BC,26(20.5%)CRF01_AE,and 23(18.1%)CRF55_01B.Differences in gender and marital status composition among individuals infected with different subtypes were statistically significant(P<0.05),while no statistically significant differences were observed in age and mode of infection composition.Conclusion The distribution of HIV-1 subtypes in Dongguan is complex and diverse,with CRF07_BC,CRF01_AE,and CRF55_01B being predominant.Furthermore,significant differences exist among HIV-infected individuals of different genders and marital statuses.关键词
