From the Guidelines
I strongly recommend switching Jerry's antibiotic from a quinolone to either doxycycline 100mg twice daily for 5-7 days or cefuroxime (Ceftin) 500mg twice daily for 5-7 days to treat his COPD exacerbation, as the concurrent use of quinolones with steroids significantly increases the risk of tendon rupture, making this combination potentially dangerous 1. Jerry's chart indicates his UTI symptoms are minimal and likely don't require specific treatment beyond what the respiratory antibiotic will provide.
Key Considerations
- Quinolones should be reserved for situations where alternative antibiotics are ineffective or contraindicated due to their serious side effect profile, including tendinopathy, peripheral neuropathy, and mental health effects.
- Doxycycline offers good coverage against respiratory pathogens including atypical organisms, while Ceftin provides effective coverage against common respiratory bacteria.
- Both are safer options when steroids are needed for COPD exacerbation management, as evidenced by the European Respiratory Society/American Thoracic Society guideline on COPD exacerbations 1.
- The European Association of Urology guidelines on urological infections also recommend avoiding ciprofloxacin and other fluoroquinolones for empirical treatment of complicated UTI in patients from urology departments or when patients have used fluoroquinolones in the last 6 months 1.
Recommendations
- Please document this medication change in Jerry's chart and ensure he understands the new prescription.
- Monitor Jerry's condition closely for any signs of tendon rupture or other adverse effects, and adjust the treatment plan as needed.
From the Research
Concerns with Quinolone Use
- The use of quinolones has been associated with an increased risk of tendinopathy, particularly in elderly persons, non-obese individuals, and those with concurrent use of glucocorticoids 2.
- Quinolone therapy can be associated with specific risks, including Clostridium difficile-associated diarrhea, and should be avoided in patients with known prolongation of the QT interval or other risk factors for tachyarrhythmia 3.
- The risk of quinolone-associated tendon rupture is more pronounced among elderly persons, non-obese patients, and individuals with concurrent use of glucocorticoids or chronic renal diseases 3, 2.
Alternative Antibiotic Choices
- For COPD exacerbation, doxycycline or ceftin may be recommended as alternative antibiotic choices 4, 5.
- Macrolide antibiotics, such as azithromycin, have been shown to reduce exacerbations in COPD patients, but the use of quinolones is not recommended due to the increased risk of tendinopathy 4, 5.
UTI Treatment
- For uncomplicated lower urinary tract infections, sulfonamides, trimethoprim-sulfamethoxazole, nitrofurantoin, and nalidixic acid may be useful, but quinolones are not typically recommended as a first-line treatment 6.
Patient-Specific Considerations
- The patient's age, sex, obesity status, and steroid use should be taken into account when considering the use of quinolones, as these factors may increase the risk of tendinopathy 2.
- The patient's medical history, including any previous experiences with antibiotic use, should also be considered when selecting an antibiotic regimen 4, 5.
