Abstract

BACKGROUND: Cutaneous leishmaniasis is one of the most neglected tropical diseases increasing in its public health importance. In Ethiopia over 28 million people are living at risk of infection. METHOD: Institution based cross-sectional study was conducted at Borumeda Hospital from February to May 2019. A total 205 leishmaniasis suspected patients were included by systematic random sampling technique. Socio demographic characteristics were collected using pre-tested questionnaires. Parasitological investigation was done from skin slit sample by using Geimsa staining method. Species identification was done by PCR-RFLP. Data were entered in to EpiData version 3.1 and analyzed using SPSS version 20 software. P-value of ≤ 0.05 was considered as statistically significant. RESULT: A total of 205 participants consisting 59% male and 41% female included in this study. The mean age (±SD) of the study participants was 31.9 (±14.29). The overall prevalence of cutaneous leishmaniasis was 22.4% (46/205). The prevalence in males (13.7%) was higher than in females (8.8%). It was more prevalent in the age group 16-45years old (15.6%). Clinically, 60% of patients' hade single lesion with 1.55 average number of lesions. About 30.7% of patients' had indurated plaque type of lesion. Most of the lesions were found on head and face (59%). House near to farmland, presence of hyrax in the village and presence of other cutaneous leishmaniasis cases in the neighborhood were independent predicator of cutaneous leishmaniasis prevalence. L.aethopica was found to be the etiologic agent of cutaneous leishmaniasis in the study participants. CONCLUSION: The prevalence of cutaneous leishmaniasis was 22.4%, this alerts the need of intervention. It is statistically associated with house near to farm land, presence of other cutaneous leishmaniasis cases in the neighborhood and presence of hyrax in village. Head and face were the most common sites of lesion.

摘要

背景:皮肤利什曼病是被忽视的热带病之一,其公共卫生重要性日益增加。在埃塞俄比亚,超过 2800 万人面临感染风险。

方法:本研究为 2019 年 2 月至 5 月在博鲁梅达医院进行的基于机构的横断面研究。采用系统随机抽样技术,共纳入 205 例疑似皮肤利什曼病患者。采用预测试卷收集社会人口统计学特征。采用 Geimsa 染色法从皮肤划痕样本中进行寄生虫学检查。采用 PCR-RFLP 进行种属鉴定。数据录入 EpiData 版本 3.1 并使用 SPSS 版本 20 软件进行分析。P 值≤0.05 为统计学显著。

结果:本研究共纳入 205 名参与者,其中 59%为男性,41%为女性。研究参与者的平均年龄(±SD)为 31.9(±14.29)岁。皮肤利什曼病的总患病率为 22.4%(46/205)。男性(13.7%)的患病率高于女性(8.8%)。在 16-45 岁年龄组更为常见(15.6%)。临床方面,60%的患者有单个病变,平均病变数为 1.55 个。约 30.7%的患者有硬结斑块型病变。大多数病变位于头部和面部(59%)。靠近农田的房屋、村庄中有岩狸以及附近有其他皮肤利什曼病病例是皮肤利什曼病流行的独立预测因子。研究参与者中发现了利什曼原虫。

结论:皮肤利什曼病的患病率为 22.4%,这提醒需要进行干预。它与靠近农田的房屋、附近有其他皮肤利什曼病病例以及村庄中有岩狸有关。头部和面部是最常见的病变部位。
