There are limited data describing the relationship between hearing loss and kanamycin pharmacokinetics (PK). We explored the association of kanamycin PK with hearing loss in patients on MDR-TB treatment.Design: We prospectively recruited patients on kanamycin-based MDR-TB treatment in Cape Town. Hearing thresholds from 0.25 to 16 kHz were tested at baseline and at 4, 8 and 12 weeks. We determined kanamycin concentrations at steady-state in serial plasma samples over 10 h, and explored factors associated with hearing loss.Study sample: One hundred and two participants including 58 (56.9%) men had analysable audiometric data; median age was 34.9 years, 65 (63.7%) were HIV-positive, and 24 (23.5%) had been treated for MDR-TB previously.Results: Eighty-four participants (82.4%) developed hearing loss. We found a 3% (95% CI: 1-6%, p = 0.028) increased risk of cochleotoxicity for each 10 µg h/L increase in 0-10 h AUC.Conclusion: We describe a high incidence of hearing loss in MDR-TB patients treated with kanamycin, with higher AUC_0-10 significantly associated with hearing loss.
