Antibiotic Resistance Trends Among Outpatients With Urinary Tract Infections In North Western Tanzania
Abstract
BACKGROUND Urinary tract infections (UTIs) are among the most common infections in the community and hospital settings and Enterobacteriaceae, are responsible for most infections. This study determined the prevalence and resistance trends of E. coli and K. pneumoniae to fluroquinolones and cephalosporins among out-patients diagnosed with urinary infections at a Zonal tertiary hospital in Tanzania METHODS This was a prospective cross sectional time series conducted in northern Tanzania and enrolled all out patients presenting with UTI symptoms. The study conducted for a period of six months between march 2021 to September 2021. RESULTS During the study period1582 patients were enrolled, the mean age was 20.2(SD 22.2) years and 883(55.8%) were female. The prevalence of E. coli was higher in female patients at 12.0% compared 6.7% in male. Both E. coli and K. pneumoniae were most prevalent in patients over >45 years at 13.3% and 3.2% respectively. E.coli resistance to Ceftriaxone, cefepime, and ciprofloxacin was 41.0%, 36.8% and 51.0% respectively. Resistance K. pneumoniae to ceftriaxone, cefepime, and ciprofloxacin was shown to be 52.8%, 47.4% and 28.2% respectively. Meanwhile, 76/192(39.6%) isolates were identified as ESBL. CONCLUSIONS In this setting empirical treatment of urinary tract infections with ciprofloxacin a commonly prescribed antibiotics for this diagnosis may not work in over half of patients when E,coli is the causative pathogen. Moreover, E. coli, resistance of…
