Magnitude and associated factors of bacterial urinary tract infections among paediatric patients in Arba Minch, southern Ethiopia
Abstract
Bacterial urinary tract infections (UTI) commonly occur in children; if left untreated, they may result in severe consequences such as uro-sepsis and renal damage. This study aimed to determine the bacterial profile, antimicrobial susceptibility patterns and associated factors among paediatric patients suspected of urinary tract infections in Arba Minch General Hospital (AMGH). An institution-based cross-sectional study was conducted from 01 October 2020 to 31 January 2021. A convenient sampling technique was used to recruit the participants; data were collected using a pre-tested questionnaire. To quantify the bacteria (as per the Kass count, >105CFU/ml), midstream urine samples were streaked onto bacteriological media. Isolates were identified by following standard procedures. The antibiotic susceptibility test was performed as per the Kirby–Bauer disc diffusion technique. Data were analyzed using SPSS software. Out of the 246 children included, 38 (15.4%) were found to be positive for significant bacteriuria. Isolates of Escherichia coli, 9/38 (23.7%), and Staphylococcus aureus, 9/38 (23.7%), were the most predominant. The majority of Gram-negative bacterial (GNB) isolates showed resistance towards amoxicillin-clavulanate (89.5%), ampicillin (84.6%), and ceftazidime (81%). Likewise, 76.9 and 76.5% of Gram-positive bacteria (GPB), respectively, had shown resistance towards co-trimoxazole and tetracycline. Multi-drug and extensively drug resistance were detected respectively in the case of 68.4 and 15.8% of the total isolates; ESBL production was found in 57.1% of GNB, whereas 55.6% of S. aureus were methicillin-resistant S. aureus (MRSA). The process of un-circumcision was significantly associated with UTI [(adjusted odds ratio= 3.578; 95% confidence interval: 1.263 – 10.13; p=0.016)].
