The aim of this study was to determine the prevalence of Chlamydia trachomatis infection and other sexually transmitted infections (STI) in female sex workers (FSW) in Tunisia.
188 prostitutes from three Tunisian towns were enrolled at their weekly medical visit. Demographic and sexual behaviour data were collected. C trachomatis, Neisseria gonorrhoeae, herpes simplex virus 2 (HSV-2) and human papillomavirus (HPV) were detected by PCR. Blood samples were tested for the presence of HIV, hepatitis B core, hepatitis C virus (HCV), HSV-2, C trachomatis and syphilis antibodies and Hbs antigen.
The mean age of the FSW was 34 years. They had worked in the sex industry for 6.6 years on average. Nearly all FSW (98.9%) had at least one marker of STI. A current infection was found in 86.7% of cases. Only one STI was noted in 37.2% and two or more in 49.5% of FSW. C trachomatis, N gonorrhoeae, HPV and HSV-2 PCR were positive in 72.9%, 11.2%, 44.1% and 1.1% of cases, respectively. Syphilis, HCV antibodies and Hbs antigen were detected in poor percentages, 2.7%, 1.1% and 0.5% of cases, respectively. No case of HIV infection was noted. No epidemiological or clinical factors were associated with STI. Only disturbed bacterial vaginal flora was found to be associated with C trachomatis infection.
In this study, a high rate of C trachomatis infection was observed. The detection of this microorganism should be introduced in systematic surveillance of Tunisian FSW.
本研究旨在确定突尼斯性工作者（FSW）中沙眼衣原体感染和其他性传播感染（STI）的流行率。
在每周的医疗访视中，招募了来自突尼斯三个城镇的 188 名妓女。收集人口统计学和性行为数据。通过 PCR 检测沙眼衣原体、淋病奈瑟菌、单纯疱疹病毒 2（HSV-2）和人乳头瘤病毒（HPV）。检测血液样本中 HIV、乙型肝炎核心、丙型肝炎病毒（HCV）、HSV-2、沙眼衣原体和梅毒抗体以及 Hbs 抗原的存在情况。
FSW 的平均年龄为 34 岁。她们从事性行业的平均时间为 6.6 年。几乎所有 FSW（98.9%）都至少有一个 STI 标志物。在 86.7%的病例中发现了当前感染。在 37.2%的病例中仅发现一种 STI，在 49.5%的病例中发现两种或更多种 STI。沙眼衣原体、淋病奈瑟菌、HPV 和 HSV-2 的 PCR 阳性率分别为 72.9%、11.2%、44.1%和 1.1%。梅毒、HCV 抗体和 Hbs 抗原的检出率分别为 2.7%、1.1%和 0.5%。未发现 HIV 感染病例。没有发现任何与 STI 相关的流行病学或临床因素。只有阴道菌群失调与沙眼衣原体感染有关。
在本研究中，观察到沙眼衣原体感染率较高。应在突尼斯 FSW 的系统监测中引入对该微生物的检测。
