BackgroundThe Centers for Disease Control and Prevention recommends universal retesting within 3 months after treatment of Trichomonas vaginalis infection given high rates of persistent infection or reinfection, or if this is not possible, within 12 months following treatment. Data is lacking on how often this is actually done.MethodsWe analyzed the demographic and clinical characteristics, rate of return for the recommended retesting, concordance between wet prep and nucleic acid amplification testing, and percent positivity for T. vaginalis on repeat vaginal specimens at a local public health department in Durham, North Carolina, United States.ResultsOf 193 females treated for trichomoniasis between March 1, 2021 – May 31, 2022, 83% were Black or African American and 44% between the ages of 20 and 29 years. Of these individuals, 32% had retesting performed within 3 months and 50% within 365 days after treatment. Females between the ages of 20 and 29 years were more likely to return for retesting than those between the ages of 30 and 39 years. Of those who returned for retesting, 10% were positive on repeat testing.ConclusionIn this study, 50% of females diagnosed with trichomoniasis completed retesting within 365 days. Improved scheduling of clients at the time of trichomoniasis treatment and improved identification in our electronic health record of individuals diagnosed with trichomoniasis within the prior year would likely improve retesting rates. Given the high prevalence of trichomoniasis, expanded screening of asymptomatic females in settings where this is feasible may be warranted.

2021 - 2022 年美国北卡罗来纳州达勒姆县的滴虫病和重新检测

背景鉴于持续感染或再感染率较高，疾病控制和预防中心建议在治疗阴道毛滴虫感染后 3 个月内进行普遍重新检测，或者如果不可能，则在治疗后 12 个月内进行重新检测。缺乏关于实际执行频率的数据。方法我们分析了人口统计学和临床​​特征、建议重新测试的回报率、湿法准备和核酸扩增测试之间的一致性，以及重复阴道标本中阴道毛滴虫的阳性百分比。美国北卡罗来纳州达勒姆当地公共卫生部门。结果在 2021 年 3 月 1 日至 2022 年 5 月 31 日期间接受滴虫病治疗的 193 名女性中，83% 是黑人或非裔美国人，44% 年龄在 20 至 29 岁之间。在这些人中，32% 的人在治疗后 3 个月内进行了重新测试，50% 的人在治疗后 365 天内进行了重新测试。20 至 29 岁之间的女性比 30 至 39 岁之间的女性更有可能返回重新测试。在返回重新检测的人中，10% 的重复检测结果呈阳性。 结论 在这项研究中，50% 被诊断患有滴虫病的女性在 365 天内完成了重新检测。改进滴虫病治疗时的客户安排，并改进我们的电子健康记录中对上一年诊断出滴虫病的个人的识别，可能会提高重新检测率。鉴于滴虫病的高患病率，可能有必要在可行的情况下扩大对无症状女性的筛查。
