Schistosomiasis ranks second to malaria in terms of socioeconomic and public health importance in Yemen. This study assessed the validity of a morbidity questionnaire and urine reagent strips as a rapid tool for screening schoolchildren for urinary schistosomiasis as compared with the presence of eggs in urine as the gold-standard parasitological diagnosis. The study examined urine samples and interviewed 696 children (mean age 12.5 years) attending a primary-preparatory school in south Yemen. Urinary schistosomiasis was confirmed in 126 (18.1%) children. Diagnostic performance was poor for 2 items in the morbidity questionnaire (self-reported history of previous infection and self-reported history of antischistosomal treatment). However, self-reported dysuria, self-reported haematuria in the questionnaire and microhaematuria by reagent strips (alone or with macrohaematuria) revealed good diagnostic performance. The results indicated that reagent strips are a valid method for detection of microhaematuria for identifying individuals and communities infected with Schistosoma haematobium.
在也门,血吸虫病在社会经济和公共卫生重要性方面仅次于疟疾。本研究评估了一份发病情况问卷和尿试剂条作为筛查学童泌尿生殖系统血吸虫病快速工具的有效性,并与以尿中虫卵作为金标准寄生虫学诊断方法进行比较。该研究对也门南部一所小学预科学校的696名儿童(平均年龄12.5岁)进行了尿液样本检测和访谈。确诊126名(18.1%)儿童患有泌尿生殖系统血吸虫病。发病情况问卷中的2项内容(既往感染的自我报告病史和抗血吸虫治疗的自我报告病史)诊断性能较差。然而,问卷中的自我报告尿痛、自我报告血尿以及试剂条检测的微量血尿(单独或伴有肉眼血尿)显示出良好的诊断性能。结果表明,试剂条是检测微量血尿以识别感染埃及血吸虫的个体和社区的有效方法。
