Reports of studies on the relationship between Schistosoma haematobium and urinary tract infection from different regions are conflicting. Hence, the need to determine the situation in each endemic area.
To determine if S. haematobium infection is associated with Urinary Tract Infection (UTI) among children in an endemic area of Cross River State, Nigeria.
Mid-stream urine specimen was collected under strict aseptic procedures into wide-mouthed screw-capped sterile plastic containers. All the specimens were kept in a cooler at approximately 4 degrees C for 5-10 hr before delivery to the laboratory. Urine microscopy was carried out by gram staining and urine was cultured using blood agar and Mac Conkey agar plates. Collection of urine specimens for schistosoma ova was done between 10.00 am and 2.00 pm when ova count of S. haematobium is expected to be at its peak.
Prevalence of urinary schistosomiasis was 51.0%. One hundred and seventy five (77.4%) of those infected had mild intensity of infection (<49 ova/10 ml). Significant bacteriuria was found in 2(0.9%) of the 226 children with urinary schistosomiasis and in 4(1.8%) of the 217 children without urinary schistosomiasis RR(95%CI) = 0.48 (0.089-2.59) P > 0.68.
This study has found the prevalence rate of urinary Schistosomiasis in this community to be 51% and no significant difference in the prevalence of UTI among children with urinary schistosomiasis and those without. However, considering the high prevalence of urinary schistosomiasis seen in this study, urgent control measures should be instituted to address this public health problem.
来自不同地区的关于埃及血吸虫与尿路感染之间关系的研究报告相互矛盾。因此,有必要确定每个流行地区的情况。
确定在尼日利亚克罗斯河州的一个流行地区,儿童中埃及血吸虫感染是否与尿路感染(UTI)有关。
在严格无菌操作下,将中段尿标本收集到广口带螺旋盖的无菌塑料容器中。所有标本在送达实验室前,于约4℃的冷藏箱中保存5 - 10小时。通过革兰氏染色进行尿液显微镜检查,并使用血琼脂和麦康凯琼脂平板对尿液进行培养。在上午10点至下午2点之间收集用于检测血吸虫卵的尿液标本,此时埃及血吸虫的虫卵计数预计处于峰值。
尿路血吸虫病的患病率为51.0%。175名(77.4%)感染者感染程度较轻(<49个虫卵/10毫升)。在226名患有尿路血吸虫病的儿童中,有2名(0.9%)发现有显著菌尿,在217名无尿路血吸虫病的儿童中,有4名(1.8%)发现有显著菌尿,相对危险度(95%可信区间)= 0.48(0.089 - 2.59),P > 0.68。
本研究发现该社区尿路血吸虫病的患病率为51%,患有尿路血吸虫病的儿童和未患该病的儿童在尿路感染患病率方面无显著差异。然而,鉴于本研究中观察到的尿路血吸虫病的高患病率,应立即采取控制措施以解决这一公共卫生问题。
