2018年8月,澳大利亚和瑞典学者在《Clin Infect Dis》发表了一项系统评价和Meta分析,考察了男男性行为者(MSM)暴露前预防(PrEP)人类免疫缺陷病毒(HIV)感染对性风险行为的影响。

背景:HIV PrEP可有效降低MSM HIV风险。然而,担忧依然存在,即PrEP使用者中的风险补偿会造成避孕套使用的减少,并增加其他性疾病传播感染(STIs)的风险。研究者评估了PrEP对MSM性风险结局的影响。

方法:研究者进行了一项开放性研究的系统评价,这些研究发表于2017年8月以前,报告了HIV阴性MSM和变性女性在每天口服PrEP的情况下的性风险结局。使用随机效应Meta分析计算了汇总效应评估值,进行了定性审核和风险偏倚评估。

结果:16项观察性研究和1项开放性试验符合入组标准。总共包含4388名参与者的8项研究报告了STI患病率,总共包含5008名参与者的13项研究报告了避孕套使用的改变。暴露前预防与直肠衣原体的显著增加相关(比值比[OR],1.59;95% 置信区间[CI],1.19~2.13),与任何STI诊断的显著增加相关(OR,1.24;95% CI,0.99~1.54)。PrEP使用与STI诊断之间的相关性在后期研究中更密切。大多数研究表明,PrEP使用者中,无避孕套的性行为增加。

结论:结果强调了PrEP使用者及其性伴侣中,最小化STIs的努力的重要性。在PrEP规模放大的情况下,需要监测MSM的风险补偿,从而评估PrEP对MSM性健康的影响并制定预防策略。
