Antibiotic resistance patterns in uropathogens: insights from a Nepalese tertiary care setting.

BACKGROUND

Antimicrobial resistance in uropathogens is increasing globally, particularly in resource-limited settings such as Nepal, limiting treatment options.

OBJECTIVES

This study aimed to evaluate the antimicrobial resistance patterns of uropathogens isolated from patients with urinary tract infections (UTIs) in a tertiary care hospital in central Nepal.

DESIGN

This study utilized a retrospective study design.

METHODS

We retrospectively observed medical records from August 2023 to February 2024 at Manmohan Memorial Teaching Hospital in Nepal, focusing on patients with significant bacterial growth in urine samples and antibiotic sensitivity analysis for resistance trends.

RESULTS

Escherichia coli (E. coli) (64.7%) and Klebsiella pneumoniae (K. pneumoniae) (15.0%) were the most common uropathogens. Both showed the highest resistance to amoxicillin (>95%), while E. coli demonstrated the lowest resistance to gentamicin (7.4%) and nitrofurantoin (12.2%). Klebsiella pneumoniae also showed low resistance to gentamicin (12.0%) but higher resistance to nitrofurantoin (64.0%).

CONCLUSION

Empirical therapy, including nitrofurantoin and aminoglycosides, is a viable option for combating antimicrobial resistance in Nepal, necessitating region-specific surveillance and multicentre studies.
