Abstract:
Purpose Specific classes of antibiotics, such as aminoglycosides, have well-established adverse events producing permanent hearing loss, tinnitus, and balance and/or vestibular problems (i.e., ototoxicity). Although these antibiotics are frequently used to treat pseudomonas and other bacterial infections in patients with cystic fibrosis (CF), there are no formalized recommendations describing approaches to implementation of guideline adherent ototoxicity monitoring as part of CF clinical care. Method This consensus statement was developed by the International Ototoxicity Management Working Group (IOMG) Ad Hoc Committee on Aminoglycoside Antibiotics to address the clinical need for ototoxicity management in CF patients treated with known ototoxic medications. These clinical protocol considerations were created using consensus opinion from a community of international experts and available evidence specific to patients with CF, as well as published national and international guidelines on ototoxicity monitoring. Results The IOMG advocates four clinical recommendations for implementing routine and guideline adherent ototoxicity management in patients with CF. These are (a) including questions about hearing, tinnitus, and balance/vestibular problems as part of the routine CF case history for all patients; (b) utilizing timely point-of-care measures; (c) establishing a baseline and conducting posttreatment evaluations for each course of intravenous ototoxic drug treatment; and (d) repeating annual hearing and vestibular evaluations for all patients with a history of ototoxic antibiotic exposure. Conclusion Increased efforts for implementation of an ototoxicity management program in the CF care team model will improve identification of ototoxicity signs and symptoms, allow for timely therapeutic follow-up, and provide the clinician and patient an opportunity to make an informed decision about potential treatment modifications to minimize adverse events.

Insights
Aminoglycoside antibiotics can cause hearing loss in cystic fibrosis (CF) patients. This study provides recommendations for monitoring ototoxicity, including routine screenings and evaluations, to improve patient outcomes.
Area of Science:
- Otolaryngology
- Pharmacology
- Pulmonology
Background:
- Aminoglycosides are crucial for treating Pseudomonas infections in cystic fibrosis (CF).
- These antibiotics carry a risk of ototoxicity, leading to hearing loss and vestibular dysfunction.
- Current CF care lacks standardized protocols for monitoring aminoglycoside-induced ototoxicity.
Purpose of the Study:
- To develop formalized recommendations for implementing guideline-adherent ototoxicity monitoring in CF patients receiving aminoglycosides.
- To address the clinical need for proactive management of ototoxicity in this vulnerable population.
Main Methods:
- Consensus statement developed by the International Ototoxicity Management Working Group (IOMG).
- Incorporated expert opinion and existing evidence specific to CF patients.
- Utilized national and international guidelines on ototoxicity monitoring.
Main Results:
- Four key recommendations for ototoxicity management in CF patients:
- Integrate hearing, tinnitus, and balance assessments into routine CF history.
- Employ timely point-of-care measures for early detection.
- Establish baseline and post-treatment evaluations for each ototoxic drug course.
- Conduct annual hearing and vestibular evaluations for all patients with prior ototoxic exposure.
Conclusions:
- Implementing a structured ototoxicity management program within the CF care team is essential.
- Improved identification of ototoxicity signs and symptoms facilitates timely interventions.
- Proactive monitoring empowers clinicians and patients to make informed treatment decisions, minimizing adverse events.
