BACKGROUND: Cutaneous leishmaniasis (CL) is a major health problem in Yemen and is endemic in many rural areas across the country. METHODS: A community-based cross-sectional survey followed by unmatched case-control comparisons was conducted among 612 participants in Utmah district, western Yemen. A total of 223 participants were included in the case-control analysis to identify the significant risk factors. Skin scrapping samples were examined by microscopy and internal transcribed spacer 1 nested polymerase chain reaction. RESULTS: Overall, 33% (202/612) of the participants had active skin lesions and/or scars that met the clinical criteria for CL. A total of 90 (14.7%) participants had suspected active CL lesions; however, a prevalence of 8.7% (53/612) was obtained based on molecular and parasitological examination, with Leishmania tropica being the only causative agent identified. Multivariable logistic regression analyses showed that being ≤10 y old, being female, living in houses with cracked walls, living in the presence of other family members with typical ulcerating skin diseases and sleeping outside were factors significantly associated with an increased likelihood of having CL. Moreover, keeping livestock on the ground floor of the house was significantly associated with a decreased likelihood of having CL. CONCLUSION: The study reveals an alarmingly high prevalence of CL among the studied population. Therefore there is an urgent need for effective control measures and improved treatment efforts against this devastating disease.
背景:皮肤利什曼病(CL)是也门的一个主要健康问题,在该国许多农村地区流行。
方法:在也门西部乌特马赫区,对 612 名参与者进行了基于社区的横断面调查,随后进行了不匹配的病例对照比较。在病例对照分析中共有 223 名参与者,以确定显著的危险因素。皮肤刮片样本通过显微镜和内部转录间隔区 1 嵌套聚合酶链反应进行检查。
结果:总体而言,612 名参与者中有 33%(202/612)有符合 CL 临床标准的活动性皮肤病变和/或疤痕。共有 90 名(14.7%)参与者有疑似活动性 CL 病变;然而,基于分子和寄生虫学检查,患病率为 8.7%(53/612),仅鉴定出利什曼原虫为唯一的病原体。多变量逻辑回归分析表明,年龄≤10 岁、女性、居住在墙壁有裂缝的房屋中、居住在有典型溃疡性皮肤病的其他家庭成员在场以及在户外睡觉是与 CL 可能性增加相关的因素。此外,将牲畜饲养在房屋的底层与 CL 可能性降低显著相关。
结论:该研究揭示了研究人群中 CL 发病率高得惊人。因此,迫切需要采取有效的控制措施和改进治疗努力来应对这种破坏性疾病。
