Bacterial and Fungal Profile, Antibiotic Susceptibility Patterns of Bacterial Pathogens and Associated Risk Factors of Urinary Tract Infection Among Symptomatic Pediatrics Patients Attending St. Paul's Hospital Millennium Medical College: A Cross-Sectional Study.

Abstract

BackgroundUrinary tract infection is a common infection in pediatrics. Understanding the common etiology of urinary tract infections, their antimicrobial susceptibility pattern, and associated risk factors in a particular setting can provide evidence for the appropriate treatment of the cases.PurposeThe current study is aimed to determine the common etiology and prevalence of uropathogens associated with urinary tract infection, as well as the antibiotic susceptibility profile of bacterial isolates, and to identify risk factors associated with urinary tract infection among pediatric patients.Materials and MethodsThe study was conducted at St. Paul Hospital Millennium Medical College between October 2019 and July 2020. Urine was collected aseptically from patients, inoculated onto culture media, and incubated at 37 °C for 18–48 hours. Bacteria and yeast were identified following standard procedures. Antibiotic susceptibility testing of bacterial pathogens was carried out by the Kirby Bauer disc diffusion method. Descriptive statistics and logistical regressions were used to estimate the crude ratio with a 95% confidence interval. P-value < 0.05 was considered significant.ResultsSignificant bacterial/fungal growth was observed in 65 samples giving a prevalence of 28.6% of which 75.4% (49/65) and 24.6% (16/65) were bacterial and fungal pathogens, respectively. About 79.6% of bacterial etiology were Escherichia coli and Klebsiella pneumoniae. The highest resistance was observed against ampicillin (100%), cefazolin (92.1%), and trimethoprim-sulfamethoxazole (84.1%), both of which are commonly used for empirical treatment in Ethiopia. Length of hospital stay (P=0.01) and catheterization (P=0.04) were statistically associated with urinary tract infection.ConclusionThe high prevalence of urinary tract infection was observed in our study. Enterobacteriaceae were the major cause of urinary tract infection. Length of hospital stay and catheterization were significantly associated with urinary tract infection. Both Gram-negative and Gram-positive bacteria were extremely resistant to ampicillin and trimethoprim-sulfamethoxazole.
