Abstract
BACKGROUND
Urinary tract infection (UTI) is considered one of the most prevalent infections that may lead to many renal complications. They account for almost 10% of all infections in Saudi Arabia, making them the second most common cause of emergency department admissions. Bacterial pathogens, primarily Escherichia coli, Klebsiella spp., Enterococcus spp., Proteus spp., and Staphylococcus spp. are the most causative agents of UTI. This study aims to evaluate the prevalence and antimicrobial susceptibility patterns of uropathogens in adult patients from Madinah, Saudi Arabia.
METHODS
A retrospective cross-sectional study was performed using data collected from patients who visited King Fahad General Hospital in Madinah, Saudi Arabia. Data included 16,803 urine bacterial cultures and their antimicrobial susceptibility profiles collected between January 2019 and October 2021.
RESULTS
Among the 16,803 tested samples, 3937 (23.4%) showed positive results for urine bacterial cultures. UTI prevalence was slightly higher in women (52.1%) than men (47.9%). Escherichia coli (29.8%) was the most prevalent, followed by Klebsiella spp. (23.2%) and Pseudomonas spp. (8.4%). As for Gram-positive bacteria, Enterococcus spp. (10.8%) were most common, followed by Streptococcus spp. (8%) and Staphylococcus spp. (3.3%). Gram-negative bacteria exhibited high resistance rates toward aztreonam (> 83.3%), ampicillin (78.8%), and cephalexin (68.5%). Enterococcus spp. displayed elevated resistance rates (> 62.3%) against ciprofloxacin, gentamicin, and tetracycline. Conversely, Streptococcus spp. showed substantial resistance rates (> 76.6%) toward colistin and trimethoprim/sulfamethoxazole.
CONCLUSION
To optimize therapy and minimize the risk of multidrug-resistant uropathogenic infections, physicians should consider the local epidemiological trends and antimicrobial resistance patterns of prevalent uropathogens prior to initiating any empirical antibacterial therapy.
