Overview

Significance Psoriasis, a common immune-mediated disease, affects approximately 2 % of the population worldwide. Sudden sensorineural hearing loss (SSNHL) might be a manifestation of systemic vascular involvement in autoimmune disease. However, to the best of our knowledge, there is no systematic English-language examination of the risk of SSNHL in patients with psoriasis. Objectives We tested the hypothesis that psoriasis is a risk factor for developing SSNHL. Methods Using Taiwan’s National Health Insurance Research Database, we conducted a retrospective cohort study to compare patients diagnosed with psoriasis from January 1, 2001 through December 31, 2006 ( n  = 28,817) with gender-, age-, and comorbidities-matched controls ( n  = 28,817). We followed each patient until the end of 2011 and evaluated the incidence of SSNHL for at least 6 years after the initial psoriasis diagnosis. Results The incidence of SSNHL was 1.51 times higher in the psoriasis cohort than in the control cohort (7.12 vs 4.73 per 10,000 person-years). Using Cox proportional hazard regressions, the adjusted hazard ratio (AHR) was 1.51 (95 % confidence interval [CI] 1.18–1.93). Comorbid hypertension was an independent risk factor for SSNHL (AHR 1.49; 95 % CI 1.05–2.13). However, the incidence rate ratios (IRRs) for each comorbidity subgroup in the psoriasis and control cohorts were not significantly different. Conclusions and Relevance Psoriasis was significantly associated with a higher risk of developing SSNHL. We suggest that physicians advise patients with psoriasis to seek medical attention if they have hearing impairments, because they may also have a higher risk of developing SSNHL.
