Data from a randomized trial of oral periodic presumptive treatment (PPT) to reduce vaginal infections were analyzed to assess the effect of the intervention on a healthy vaginal environment (normal flora confirmed by Gram stain with no candidiasis or trichomoniasis). The incidence of a healthy vaginal environment was 608 cases per 100 person-years in the intervention arm and 454 cases per 100 person-years in the placebo arm (hazard ratio [HR], 1.36; 95% confidence interval [CI], 1.17-1.58). Sustained vaginal health (healthy vaginal environment for ≥3 consecutive visits) was also more frequent in the intervention arm (HR, 1.69; 95% CI, 1.23-2.33). PPT is effective at establishing and sustaining a healthy vaginal environment.
对口服周期性推定治疗(PPT)减少阴道感染的随机试验数据进行了分析,以评估该干预措施对健康阴道环境(革兰氏染色证实无假丝酵母菌或滴虫感染的正常菌群)的影响。干预组中健康阴道环境的发生率为每 100 人年 608 例,安慰剂组为每 100 人年 454 例(风险比[HR],1.36;95%置信区间[CI],1.17-1.58)。干预组中持续的阴道健康(连续 3 次就诊时健康的阴道环境)也更为频繁(HR,1.69;95%CI,1.23-2.33)。PPT 可有效建立和维持健康的阴道环境。
