Depot medroxyprogesterone acetate (DMPA) use among HIV-1-infected women may increase transmission by increasing plasma and genital HIV-1 RNA shedding. We investigated associations between DMPA use and HIV-1 RNA in plasma and cervical secretions. One hundred two women initiated antiretroviral therapy, contributing 925 follow-up visits over a median of 34 months. Compared with visits with no hormonal contraception exposure, DMPA exposure did not increase detection of plasma (adjusted odds ratio: 0.81, 95% confidence interval: 0.47 to 1.39) or cervical HIV-1 RNA (adjusted odds ratio: 1.41, 95% confidence interval: 0.54 to 3.67). Our results suggest that DMPA is unlikely to increase infectivity in HIV-positive women who are adherent to effective antiretroviral therapy.
HIV-1 感染妇女使用 depot 醋酸甲羟孕酮(DMPA)可能会增加血浆和生殖器 HIV-1 RNA 的脱落,从而增加传播风险。我们研究了 DMPA 使用与血浆和宫颈分泌物中 HIV-1 RNA 之间的关联。102 名妇女开始接受抗逆转录病毒治疗,在中位数为 34 个月的随访中提供了 925 次就诊。与没有激素避孕暴露的就诊相比,DMPA 暴露并未增加血浆中 HIV-1 RNA 的检出率(调整后的优势比:0.81,95%置信区间:0.47 至 1.39)或宫颈 HIV-1 RNA 的检出率(调整后的优势比:1.41,95%置信区间:0.54 至 3.67)。我们的结果表明,对于坚持有效抗逆转录病毒治疗的 HIV 阳性妇女,DMPA 不太可能增加传染性。
