Asymptomatic bacteriuria (ASB) is benign except in certain medical conditions such as pregnancy and immunosuppression. In Ghana, there are hardly any studies on urinary infections among sickle cell disease (SCD) patients, and the few studies carried out in Africa focused on pediatric SCD populations. The current study aimed to investigate the risk of ASB among SCD patients at a tertiary hospital in Ghana. This was a cross-sectional study involving 110 SCD patients and 110 age and sex matched healthy controls. Urine specimens were collected from all the study subjects and analyzed by standard microbiological methods. Demographic information were also collected from the study subjects. The overall ASB prevalence was significantly higher among SCD patients (17.2%) than among the control group (8.2%), and the relative risk was 2.11 ( = 0.0431; CI = 1.00-4.45). Being female was as a predictor of ASB among the SCD patients (OR = 14.76; CI = 11.23-18.29; = 0.0103). The most common organism isolated from the study participants was coagulase negative species (4.1%), followed by (2.7%); etiology of ASB in the SCD patients was more diverse compared to healthy people. All the isolates were susceptible to amikacin, sparfloxacin and norfloxacin but resistant to ampicillin.
无症状菌尿(ASB)通常是良性的,但在某些医学状况下,如妊娠和免疫抑制时除外。在加纳,几乎没有关于镰状细胞病(SCD)患者尿路感染的研究,而在非洲开展的少数研究聚焦于儿童SCD人群。本研究旨在调查加纳一家三级医院SCD患者中ASB的风险。这是一项横断面研究,纳入了110例SCD患者和110例年龄及性别匹配的健康对照。从所有研究对象中收集尿液标本,并采用标准微生物学方法进行分析。还从研究对象处收集了人口统计学信息。SCD患者中ASB的总体患病率(17.2%)显著高于对照组(8.2%),相对风险为2.11(P = 0.0431;CI = 1.00 - 4.45)。女性是SCD患者中ASB的一个预测因素(OR = 14.76;CI = 11.23 - 18.29;P = 0.0103)。从研究参与者中分离出的最常见病原体是凝固酶阴性葡萄球菌(4.1%),其次是大肠杆菌(2.7%);与健康人相比,SCD患者中ASB的病因更多样化。所有分离出的菌株对阿米卡星、司帕沙星和诺氟沙星敏感,但对氨苄西林耐药。
