Community-acquired urinary tract infections due to extended-spectrum β -lactamase-producing organisms in United Arab Emirates
Abstract
BACKGROUND: The epidemiology of extended-spectrum β-lactamase (ESBL)-producing bacteria is fast evolving with increasing global trend towards community-acquired infections. Limited information available about ESBLs therapy outcomes and control strategies, especially in the Middle Eastern countries.
METHODS: We studied 399 ESBL-producing Escherichia coli and Klebsiella pneumoniae isolates from urinary tract infections (UTIs) occurred between 2014 and 2016 in University Hospital Sharjah. We included 124 ESBL-negative E. coli and K. pneumoniae isolates from UTIs as controls. Pearson Chi squares test and independent t-test were used to compare difference between ESBL positives and negatives. Multivariate logistic regression analysis was also performed.
RESULTS: Approximately 75% of the E. coli and K. pneumoniae isolates causing UTIs were community-acquired. We found that recurrent UTIs, old age, and catheterization among other risk factors for community-acquired ESBL-positive UTIs. Majority of these ESBL-positive isolates were resistant to antibiotics such as ciprofloxacin (74%) and trimethoprim-sulphamethoxazole (73%) that are commonly used for treatment of community-acquired urinary tract infections.
CONCLUSIONS: ESBL-producing E. coli and K. pneumoniae have become major etiological pathogens of community-acquired UTIs in the United Arab Emirates. Healthcare providers should implement better infection control strategies and careful use of antimicrobials especially in…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence.
