A large new study has revealed that children diagnosed with vitiligo are at significantly higher risk for certain types of hearing loss compared to their peers without the condition. The research, published online June 11 in JAMA Dermatology, analyzed data from over 21,000 pediatric patients with vitiligo and an equal number of matched controls across 89 U.S. healthcare organizations between 2016 and 2024.
Key Findings
-
Higher Risk of Sensorineural and Mixed Hearing Loss: Children with vitiligo showed notably increased risks for sensorineural hearing loss (SNHL) and mixed hearing loss, but not for conductive hearing loss, when compared to matched peers without vitiligo.
-
Sensorineural Hearing Loss (SNHL): Hazard ratio (HR) 1.86; 95% confidence interval (CI), 1.38–2.51.
-
Mixed Hearing Loss: HR 2.10; 95% CI, 1.29–3.44.
-
-
Risk Increases Over Time: The risk for SNHL became more pronounced with longer follow-up periods—rising to an HR of 2.03 (95% CI, 1.21–3.41) after 1–3 years and 2.56 (95% CI, 1.55–4.22) after more than 3 years. Mixed hearing loss risk was elevated only in the first year of follow-up.
-
No Significant Increase in Ocular Disorders: The study found no significant differences in the risk for most ocular conditions, including vision impairment, dry eye, uveitis, or glaucoma. There was a slight elevation in risk for retinal and choroidal disorders, but this was not consistent in sensitivity analyses.
Expert Commentary
“Our observation of increased SNHL risk, particularly after the first year of follow-up, aligns with the theory that hearing loss develops progressively through cumulative cochlear damage, correlating with disease duration and extent,” the study authors wrote. They emphasized the need for further prospective studies to clarify the underlying mechanisms and to guide clinical practice.
Background on Vitiligo and Hearing Loss
Vitiligo is an autoimmune disorder in which the immune system attacks melanocytes—cells responsible for producing pigment—not only in the skin but also in other tissues, including the inner ear. Previous research has suggested that the destruction of melanocytes in the cochlea can lead to hearing loss, particularly sensorineural hearing loss.
Conflicting Research
While this study found a strong association between pediatric vitiligo and hearing loss, other recent research has reported no significant difference in hearing loss rates between children with vitiligo and controls. A separate study published in Pediatric Dermatology found an 18% incidence of hearing loss in vitiligo patients versus 15% in controls, which was not statistically significant. This highlights ongoing debate and the need for further research.
Limitations
The study was limited by its retrospective design, reliance on diagnostic codes, and lack of data on vitiligo severity, phenotypes, location, or audiometry findings. Audiologist or dermatologist diagnoses were not independently verified, and the rarity of some outcomes could have introduced bias.
