Chronic kidney disease is associated with increased risk of sudden sensorineural hearing loss and Ménière’s disease: a nationwide cohort study

Abstract

AbstractSeveral studies have demonstrated the harmful effects of chronic kidney disease (CKD) on the audiovestibular system. Through a time-to-event analysis, we aimed to compare the association of CKD with sudden sensorineural hearing loss (SSNHL), and Ménière’s disease against a control population without CKD. We used a total of 1,025,340 patients from the Korean National Health Insurance Service database from 2002 to 2013. The CKD group (n = 2572) included patients diagnosed with CKD more than three times between January 2003 and December 2005. The non-CKD group (n = 5144) consisted of two patients without CKD for every patient with CKD. Each patient was monitored until December 2013. We calculated the incidence, survival rate, and hazards ratio (HR) of SSNHL and Ménière’s disease. In the CKD group, the incidence of SSNHL and Ménière’s disease was 1.39 and 3.64 per 1000 person-years, respectively. Patients with CKD showed an adjusted HR of 2.15 and 1.45 for SSNHL and Ménière’s disease, respectively. Middle-aged patients with CKD were associated with a higher incidence of developing SSNHL and Ménière’s disease than those without CKD. Female patients with CKD had a higher risk of developing SSNHL; however, there was no significant difference in the risk of Ménière’s disease in patients with CKD according to sex. Our findings suggest that CKD is associated with an increased incidence of SSNHL and Ménière’s disease. Therefore, audiovestibular surveillance should be considered in patients with CKD.
