Abstract

Background: Vitiligo is an acquired depigmentation disease of the skin due to melanocyte destruction. A shared pathogenesis affecting melanocytes in the cochlea has been postulated. However, the association between vitiligo and sensorineural hearing loss (SNHL) is unclear.

Objective: To identify the association between vitiligo and SNHL.

Methods: This retrospective, nationwide cohort study included patients with vitiligo and age-, sex- and comorbidities-matched controls (propensity score matching; 1:4 ratio) from the National Health Insurance Research Database in Taiwan from 1 January 2000 to 31 December 2013.

Results: In total, 13 048 patients with vitiligo and 52 192 controls were included. SNHL developed in 0.61% patients with vitiligo and 0.29% controls. After adjusting for sex, age and comorbidities, a significant association between vitiligo and SNHL was found (adjusted hazard ratio, 2.18; 95% CI, 1.66-2.86). The other risk factors for developing SNHL included increased age, male sex, hyperlipidaemia, coronary artery disease and diffuse connective tissue diseases. In subgroup analysis, the association between vitiligo and SNHL remained significant in almost all the subgroups.

Conclusion: A 2.2-fold increased risk of developing SNHL was found in patients with vitiligo. Proper referral to otologists for early screening and closer follow-up of SNHL should be considered for patients with vitiligo, especially for patients with older age.
