埃及血吸虫病的诊断一般依靠单次尿虫卵检查,虫卵的逐日变化和日周期变化可能导致判断疾病患病率和发病率的错误结论。本文以标准化方法收集尿液,比较了尿虫卵计数、循环抗原水平和尿试剂条指数(RSI)的逐日变化。并评价感染度和血尿、尿白细胞、尿蛋白、尿循环阳极抗原(CAA)、循环阴极抗原(CCA)浓度的关系以及在疗效考核中的作用。
The diagnosis of schistosomiasis in Egypt generally relies on a single urine egg test. Daily changes in the eggs and changes in the diurnal cycle may lead to wrong conclusions as to the prevalence and morbidity of the disease. Urine was collected by a standardized method and the daily changes of urinary egg counts, circulating antigen levels and urine reagent strip index (RSI) were compared. The relationship between infection degree and hematuria, urinary leucocytes, urinary protein, urinary circulating anodic antigen (CAA) and circulating cathodic antigen (CCA) were also evaluated.
