Cutaneous leishmaniasis (CL), caused by an obligate intracellular protozoan parasite from the genus Leishmania, imposing a significant burden on underdeveloped countries especially those located in the Middle East. Four electronic databases were searched to evaluate the prevalence of CL in the Middle East. The random effects model (95% confidence intervals (CI)) were applied to determine the overall and subgroup pooled prevalence. Heterogeneity was assessed by Cochran's Q test and I2 statistics. Among 2424 peer-reviewed papers, 37 datasets from 34 studies were included in the current meta-analysis. 285560 individuals were assessed across 9 Middle Eastern countries. The pooled prevalence of CL was estimated at 12% (95% CI 9-15 %; 10718/285560). The highest prevalence rate was observed in Syria (39%, 37-42%), and the lowest one was found in Iraq and Lebanon (0%, 0-1%). The prevalence of CL in studies that applied LST assays had the highest rate (48%, 17-80%). The infection rate in males was similar to females (7%, 4-10%). The prevalence of infection in individuals living in urban areas was higher than in rural areas (14%, 10-19%). The prevalence of CL in the age group 0-15 years was higher than in individuals 16-40 and >40 years (9%, 6-13%). Most of the lesions were found on the face, and single lesions were more prevalent than two and three ones. In conclusion, the occurrence of CL was considerable in Middle Eastern countries. Therefore, more efforts should be made to precisely report the CL in this region for developing appropriate preventive and controlling strategies. .
皮肤利什曼病(CL)是由利什曼原虫属的专性细胞内原生动物寄生虫引起的,给欠发达国家,尤其是位于中东的国家带来了沉重负担。为了评估中东地区 CL 的流行情况,我们检索了四个电子数据库。采用随机效应模型(95%置信区间[CI])确定总体和亚组汇总流行率。采用 Cochran's Q 检验和 I2 统计评估异质性。在 2424 篇同行评议论文中,有 37 个数据集来自 34 项研究被纳入本次荟萃分析。共有 9 个中东国家的 285560 人参与评估。CL 的总流行率估计为 12%(95%CI 9-15%;10718/285560)。CL 的最高流行率见于叙利亚(39%,37-42%),最低见于伊拉克和黎巴嫩(0%,0-1%)。应用 LST 检测的研究中,CL 的流行率最高(48%,17-80%)。男性的感染率与女性相似(7%,4-10%)。居住在城市地区的个体感染率高于农村地区(14%,10-19%)。0-15 岁年龄组的感染流行率高于 16-40 岁和>40 岁年龄组(9%,6-13%)。大多数病变发生在面部,单发病变比两个和三个病变更为常见。总之,中东国家 CL 的发生率相当高。因此,应该更加努力地精确报告该地区的 CL 情况,以便制定适当的预防和控制策略。
