Exploring Antibiotic Resistance Patterns in Escherichia coli Isolates from Urinary Tract Infections: A Retrospective...

Area of Science:

• Infectious Diseases
• Microbiology
• Clinical Pharmacy

Background:

• Urinary tract infections (UTIs) are common, with Escherichia coli (E. coli) being the primary causative agent.
• Rising antimicrobial resistance necessitates updated antibiotic sensitivity profiles for effective treatment.
• Empiric antibiotic therapy for UTIs requires accurate local resistance data to ensure efficacy.

Purpose of the Study:

• To update the antibiotic sensitivity profiles of E. coli causing UTIs in adult patients in Jordan.
• To assess the resistance patterns of E. coli to commonly prescribed empiric antibiotics.
• To provide data for guiding appropriate antibiotic selection in UTI management.

Main Methods:

• Retrospective analysis of E. coli UTI cases from January 2019 to July 2021.
• Data collection included patient demographics, prescribed empiric antibiotics, and E. coli culture results.
• Antibiotic resistance was determined using clinical breakpoints based on sensitivity testing.

Main Results:

• Of 230 E. coli UTI cases, 87.4% received empiric antibiotics.
• Antibiotic sensitivity testing revealed 27% of E. coli isolates were resistant to at least one agent.
• Female patients exhibited a higher prevalence of resistant E. coli (51.5%) compared to males (30.8%).

Conclusions:

• Significant E. coli resistance to empiric antibiotics underscores the need for continuous surveillance.
• Tailoring antibiotic treatment based on patient-specific factors and local resistance data is crucial.
• Improved antibiotic stewardship can enhance clinical outcomes and combat antimicrobial resistance.
