PLOS MED:在中国男男性行为者中使用梅毒和HIV的快速双重自我检测来扩大梅毒检测的接受度

2016年全球估计有630万梅毒新病例。各国都注意到梅毒在男男性行为者(MSM)中尤其增加。

2016年全球估计有630万梅毒新病例。各国都注意到梅毒在男男性行为者(MSM)中尤其增加。在中国,1995-2016年期间,梅毒发病率从每10万人中1.0人上升到32.2人。定期梅毒检测是控制梅毒的一个关键策略。早期诊断和治疗可以防止发病率、死亡率和继续传播

在许多低收入和中等收入国家,梅毒检测率低是MSM的一个主要公共卫生问题。梅毒自我检测(SST)可以补充和扩展基于设施的检测。为了评估提供SST对提高中国MSM中梅毒检测接受率的有效性和成本,来自我国广州南方医科大学皮肤病医院的专家开展了相关研究,结果发表在PLOS MEDICINE杂志上。

在2020年1月7日至2020年7月17日期间进行了一项开放标签、平行3臂随机对照试验(RCT)。从中国26个省的124个城市招募了至少18岁、在过去一年中与男性发生过无套肛交、报告在过去6个月中没有进行过梅毒检测、有稳定住所和邮寄地址的男性。采用12个区块的随机化方法,入选者被随机分配(1:1:1)到3个组:标准护理组、标准SST组和抽奖激励的SST组。主要结果是在试验期间检测梅毒并通过照片验证的参与者比例,并通过风险差异(RDs)估计各组之间的比较。

结果共有451名男性被纳入。总共有136人(90.7%,136/150)在标准护理组,142人(94.0%,142/151)在标准SST组,137人(91.3%,137/150)在抽奖激励的SST组被纳入最终分析中。在试验期间,至少进行1次梅毒检测的男性比例在标准SST组为63.4%(95%CI:55.5%-71.3%,p=0.001),在激励的SST组为65.7%(95%CI:57.7%-73.6%,p=0.0002),而在标准护理组为14.7%(95%CI:8.8%-20.7%,p<0.001)。标准SST和标准护理组的估计RD为48.7%(95%CI:37.8%-58.4%,P<0.001)。

大多数梅毒自我检测者(78.5%,95%CI:72.7%-84.4%,P<0.001)报告从未检测过梅毒。每个被检测者的成本是:标准SST为26.55美元,激励的SST为28.09美元,而标准护理为66.19美元。

综上,与标准护理相比,提供SST显著提高了中国MSM检测梅毒的比例,而且费用更低。
