2013年上海市新发现HIV-1感染者中注射吸毒人群的基因亚型分析
HIV-1 subtype analysis in new HIV-1 infected injection drug users in Shanghai, 2013
摘要
Abstract
Objective: To investigate and analyze the epidemiological feature of human immunodeficiency virus-1 (HIV-1) subtypes infections among injection drug users, newly found and untreated in 2013, Shanghai, for stipulating scientifically and effectively the strategy for intervention. Methods: Seventy-eight cases of new HIV-1 infected injection drug users were sampled and their plasma was collected. HIV-1 pol gene was amplified by reverse transcription polymerase chain reaction(RT-PCR) and then the DNA was sequenced and analyzed by phylogenetic tree, and comprehensive analysis was performed in combination with epidemiological data. Results: Sixty-six samples(84.6%) have been successfully amplified, with the gene sub-type including 47 cases of CRF07_BC(71.2%), 12 cases of CRF01_AE (18.2%), 3 cases of CRF08_BC(4.5%) , 2 cases of sub-type B (3.0%) and 2 cases of subtype C(3.0%). The difference in distribution of CRF07_BC and CRF01_AE showed statistical significant difference by infection source (P=0.02);the 5 kinds of gene subtypes differed between residents and migrates (P<0.01). Conclusions: Genetic diversity of HIV-1 subtype infected injection drug users in Shanghai is complex, and the dominant gene subtype is CRF07_BC. More attention should be paid to this population and regular HIV-1 subtype survilliance is needed.关键词
