Emerging menace of multidrug-resistant organisms in urosepsis: Observations from western India

Area of Science:

• Infectious Diseases
• Microbiology
• Public Health

Background:

• Urosepsis, a severe urinary tract infection (UTI) complication, is increasingly caused by multidrug-resistant (MDR) organisms.
• High UTI prevalence in regions like Western India, influenced by climate and urolithiasis, exacerbates therapeutic challenges.

Purpose of the Study:

• To investigate the microbiological profile and antimicrobial resistance patterns of urosepsis cases in Western India.
• To assess the efficacy of commonly used antibiotics against MDR pathogens causing urosepsis.

Main Methods:

• Observational study of 41 microbiologically confirmed urosepsis cases over 1.5 years.
• Analysis of antimicrobial susceptibility testing results for common uropathogens.

Main Results:

• High resistance rates observed for fluoroquinolones, cotrimoxazole, and third-generation cephalosporins.
• Nitrofurantoin demonstrated significant retained activity, with 78.0% effectiveness.
• MDR pathogens are a significant driver of urosepsis in the study region.

Conclusions:

• The study highlights the growing threat of MDR pathogens in urosepsis cases in Western India.
• Nitrofurantoin shows promise as a therapeutic option, but local resistance patterns necessitate careful consideration.
• Enhanced local antimicrobial stewardship and ongoing surveillance are essential for effective empirical therapy guidance.
