Abstract:

目的了解广州市未接受抗病毒治疗的MSM人群HIV感染者（MSM感染者）耐药株流行状况。方法收集2008－2015年新确证HIV-1抗体阳性、现住址为广州市、传播途径为男男性行为传播、确证时未接受过抗病毒治疗的MSM感染者血清样本，提取HIV-1 RNA，采用巢式PCR法扩增HIV-1 pol区全部蛋白酶（PR）和部分反转录酶（RT）基因片段，测序后提交到美国斯坦福大学HIV耐药数据库进行耐药分析。结果 2 283例MSM感染者中，共有1 986例血清样本成功获得pol区基因片段，年龄16～84（30.18±8.24）岁；未婚者占74.17%（1 473/1 986）；汉族占90.64%（1 800/1 986）；大专及以上占49.65%（986/1 986），高中及中专占27.14%（539/1 986），初中及以下占20.89%（415/1 986）。HIV-1亚型以CRF07_BC和CRF01_AE为主，分别为38.22%（759/1 986）和34.49%（685/1 986）。总耐药率为3.32%（66/1 986），对蛋白酶抑制剂（PIs）耐药率为1.36%（27/1 986）），对核苷类反转录酶抑制剂（NRTIs）耐药率为0.65%（13/1 986），对非核苷类反转录酶抑制剂（NNRTIs）耐药率为1.61%（32/1 986）。B亚型对3类药物的耐药率均较高，CRF55_01B对NNRTIs耐药率高于其他亚型。B亚型对司他夫定（D4T）、依非韦仑（EFV）、奈韦拉平（NVP）的耐药率最高，均为4.17%（5/120）；其次是那非那韦（NFV）、齐多夫定（AZT）、利匹韦林（RPV），均为3.33%（4/120）。CRF55_01B对EFV、NVP的耐药率最高，均为5.50%（16/291）；其次是依曲韦林（ETR）、RPV，均为5.15%（15/291）。结论广州市未接受抗病毒治疗的MSM感染者耐药率处于低水平，现有抗病毒药物在总体上仍是有效的。但B亚型和CRF55_01B亚型耐药率相对较高，值得关注。

English Abstract:

Objective To understand the prevalence of drug resistance in treatment-naive HIV infected men who have sex with (MSM) in Guangzhou. Methods HIV-1 RNA were extracted from the serum specimens of the MSM newly confirmed to be HIV-1 positive, living in Guangzhou and receiving no anti-viral therapy from 2008 to 2015. HIV-1 pol gene segments, including full protease and part reverse transcriptase, were amplified by nested reverse transcription polymerase chain reaction (nested-PCR) and sequenced by Sanger. Subsequently, the sequence data were submitted to Stanford University HIV Drug Resistance Database for drug resistance analysis. Results Among 2 283 HIV infected MSM, HIV-1 pol gene segments were obtained from the serum samples of 1 986 HIV infected MSM aged 16-84 (30.18±8.24) years. Among them, the unmarried accounted for 74.17% (1 473/1 986), those of Han ethnic group accounted for 90.64% (1 800/1 986), those with education level of college or above accounted for 49.65% (986/1 986), those with education level of senior high school or secondary school accounted for 27.14% (539/1 986), those with education level of junior high school or below accounted for 20.89% (415/1 986). The distribution of subtypes was predominated by CRF07_BC (38.22%, 759/1 986) and CRF01_AE (34.49%, 685/1 986). The overall prevalence of drug resistance was 3.32% (66/1 986). The prevalence of resistance to protease inhibitors (PIs), nucleoside reverse transcriptase inhibitors (NRTIs) and non-nucleoside reverse transcriptase inhibitors (NNRTIs) were 1.36%(27/1 986), 0.65% (13/1 986) and 1.61% (32/1 986), respectively. Subtype B had higher resistance to PIs, NRTIs and NNRTIs and subtype CRF55_01B had highest resistance to NNRTIs compared with other subtypes. In subtype B, the resistant rates to D4T, EFV and NVP were highest (all 4.17%, 5/120), followed by those to NFV, AZT and RPV (all 3.33%, 4/120). In subtype CRF55_01B, the resistant rates to EFV and NVP were highest (all 5.50%, 16/291),followed by those to ETR and RPV (all 5.15%, 15/291). Conclusions The prevalence of drug resistance in treatment-naive HIV infected MSM in Guangzhou remained at low level and current antiretroviral drugs are generally effective. However, subtype B and CRF55_01B have higher drug resistance.
