摘要
背景：性传播感染（STI）在非洲是一个突出的健康问题，特别是在男男性行为者（MSM）等关键人群中。在这里，我们介绍了在多哥进行的一项为期2年的纵向队列研究的基线结果。方法：将200名多哥lomovel的男男性行为者纳入ANRS I MIE 12400/DepIST-H队列，其中一半为HIV携带者。肛门涂片检测高危型HPV （hrHPV）。通过尿液、咽拭子和肛门拭子检测淋病奈瑟菌（GC）和沙眼衣原体（CT）。结果：总体而言，中位年龄为23岁，hrHPV患病率为75.9%，在hiv阳性的MSM中显着更高（p = 0.008）。最常见的hrHPV类型是HPV16和HPV35（各占18.7%）。总体而言，55.4%的参与者有肛门细胞学异常，最常见的病变是低级别鳞状上皮内病变（hiv阳性的22.3%和hiv阴性的15.2%）。GC和CT的总感染率分别为32.5%和32.0%。临床肛门病变，主要是尖锐湿疣，在46.0%的参与者中检测到（n = 86）。结论：这些发现强调了性传播感染在男男性行为者中的高患病率，并证实了西非HPV类型的异常分布，其中HPV35高度流行。需要在这一关键人群中制定一项关于性传播感染筛查和HPV疫苗接种的国家战略。试验注册：NCT04910438，提交日期：2020-01-22。
High prevalence of bacterial STI, anal HPV, cytological abnormalities and anal lesions among MSM in Togo, 2021: a baseline analysis of the ANRS I MIE 12,400/DepIST-H cohort.
Background: Sexually transmitted infections (STI) are a prominent health issue in Africa, especially in key populations such as men who have sex with men (MSM). Here, we present the baseline results of a 2-year longitudinal cohort in Togo.
Methods: A total of 200 MSM in Lomé, Togo, were included in the ANRS I MIE 12400/DepIST-H cohort, half living with HIV. High-risk HPV (hrHPV) detection was performed on anal smears. Neisseria gonorrhoeae (GC) and Chlamydia trachomatis (CT) were tested from urine, pharyngeal and anal swabs.
Results: Overall, median age was 23 years, hrHPV prevalence was 75.9%, and was significantly higher in HIV-positive MSM (p = 0.008). The most common hrHPV types were HPV16 and HPV35 (18.7% each). Overall, 55.4% of participants had abnormal anal cytology, the most frequent lesions being low-grade squamous intraepithelial lesions, (22.3% of HIV-positive and 15.2% of HIV-negative MSM). The overall prevalence of GC and CT infections was 32.5% and 32.0%, respectively. Clinical anal lesions, mostly condyloma, were detected in 46.0% of participants (n = 86).
Conclusions: These findings emphasize the high prevalence of STIs among MSM and confirm the unusual distribution of HPV types in West Africa, with HPV35 being highly prevalent. A national strategy regarding STI screening and HPV vaccination in this key population is needed.
