Fluoroquinolones, antimicrobial resistance and neutropenic cancer patients.

Purpose Of Review: Fluoroquinolone antibiotics are widely used in our communities and healthcare facilities. This review focuses upon the relationship between fluoroquinolone use and the rising prevalence in neutropenic cancer patients of multidrug resistant pathogens including methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci, Clostridium difficile, and aerobic Gram-negative bacilli.

Recent Findings: Fluoroquinolones such as ciprofloxacin or levofloxacin are efficacious for the prevention and treatment of neutropenic fever syndromes, including infections due to aerobic Gram-negative bacilli.
