The cumulative effects of intravenous antibiotic treatments on hearing in patients with cystic fibrosis.

ABSTRACT:

Background

Aminoglycosides (AGs) and glycopeptides are antibiotics essential for treating life-threatening respiratory infections in patients with cystic fibrosis (CF). The goal of this study was to examine the effects of cumulative intravenous (IV)-AG (amikacin and/or tobramycin) and/or glycopeptide (vancomycin) dosing on hearing status in patients with CF.

Methods

Hearing thresholds were measured from 0.25 to 16.0kHz, in 81 participants with CF. Participants were categorized into two groups: normal hearing in both ears (≤25dB HL for all frequency bands) or hearing loss (>25dB HL for any frequency band in either ear). Participants were also characterized into quartiles by their cumulative IV-AG (with or without vancomycin) exposure. Dosing was calculated using two strategie
