[Non-occupational post-exposure prophylaxis in men who have sex with men in Guangxi Zhuang Autonomous Region].

Objective: To analyze the effects of HIV non-occupational post-exposure prophylaxis (nPEP) in men who have sex with men (MSM) in Nanning and Liuzhou, Guangxi Zhuang Autonomous Region. Methods: Participants were recruited through community publicity and advocacy under a "Trinity" approach among non-governmental organizations (NGO), CDCs/hospitals and pharmacies. Basic information, drug taking and follow-up tests of participants who had enrolled for 28 days of the research were collected. Descriptive statistics were used for data analysis. Results: From September 2017 to March 2019, a total of 213 MSM cases consulted for nPEP service, 159 of them were eligible for nPEP, and 154 were enrolled in the study for drug taking. For 132 cases enrolled in the study for 28 days and above, 118 completed the 28-day course of antiretroviral therapy (ART), while 10 failed to complete the 28-day course of ART, and 4 could not be confirmed whether completed the full course of ART due to loss of contact. For those who completed 28-day course of ART, 94.1% (111/118) and 75.4% (89/118) respectively received HIV tests at 4-6 weeks and 3 months after exposure, the results were all HIV negative. Conclusion: Under the "Trinity" approach, taking antiviral drugs earlier after HIV non-occupational exposure can effectively reduce the risk of HIV infection and to some extent, reduce the new infection cases.目的： 分析广西壮族自治区南宁、柳州市MSM使用抗病毒药物进行HIV非职业暴露后预防（nPEP）效果。 方法： 搭建社会组织-CDC/医院-药店（"三位一体"）的服务合作模式，通过社区宣传倡导，现场招募研究对象。收集入组研究满28 d参加者的基本信息、药物使用情况和随访检测情况，采用描述性统计进行分析。 结果： 2017年9月至2019年3月，共有213名男男性行为者咨询暴露后预防用药，其中159人符合预防用药标准，接受服药154人。入组研究满28 d的132人，其中连续服药满28 d的118人、未服药满28 d的10人、因失访无法证实是否完成服药的4人。服药满28 d的服务对象中，94.1%（111/118）于暴露后4～6周接受了HIV随访检测，75.4%（89/118）于暴露后3个月接受了HIV随访检测，结果均为阴性。 结论： 在"三位一体"模式下，发生HIV非职业暴露后尽早使用抗病毒药物预防可以降低HIV感染的风险，在一定程度上减少HIV新发感染数。.
