Hormonal changes during menstrual cycling may affect susceptibility to HIV.
We determined the simian human immunodeficiency virus (SHIV) acquisition time point in 43 cycling pigtail macaques infected by repeated vaginal virus exposures initiated randomly in the cycle.
SHIV infection was first detected in the follicular phase in 38 macaques (88%), and in the luteal phase in five macaques (12%), indicating a statistically significant timing difference. Assuming a 7-day eclipse phase, most infections occurred during or following a high-progesterone period associated with menstruation, vaginal epithelium thinning, and suppressed mucosal immunity.
This raises questions whether other high-progesterone conditions (pregnancy, hormonal contraception) similarly affect HIV risk.
月经周期中的激素变化可能会影响对艾滋病毒的易感性。
我们确定了43只处于月经周期的猪尾猕猴在通过在月经周期中随机开始的反复阴道病毒暴露感染猿猴人类免疫缺陷病毒(SHIV)的时间点。
在38只猕猴(88%)的卵泡期首次检测到SHIV感染,在5只猕猴(12%)的黄体期检测到感染,表明在时间上存在统计学显著差异。假设潜伏期为7天,大多数感染发生在与月经、阴道上皮变薄和黏膜免疫抑制相关的高孕酮期或之后。
这引发了其他高孕酮状态(怀孕、激素避孕)是否同样影响艾滋病毒感染风险的问题。
