Abstract

OBJECTIVES:: We investigated the association of idiopathic sudden sensorineural hearing loss (ISSNHL) with coenzyme Q (CoQ) and cardiovascular risk factors. STUDY DESIGN:: A prospective study. SETTING:: Hospital center. PATIENTS:: Thirty Italian patients with ISSNHL and 60 healthy Italian subjects. INTERVENTION:: Diagnostic. MAIN OUTCOME MEASURE:: Evaluation of serum CoQ levels and cardiovascular risk factors (total cholesterol, low-density lipoprotein [LDL], homocysteine [HCY]). The results were compared with variance analysis and Student's t test. Univariate and multivariate analysis were used to evaluate the association between ISSNHL and CoQ, total cholesterol, LDL, and HCY levels. RESULTS:: In our series, we found a significant association between ISSNHL and high total cholesterol (p < 0.05), high LDL (p = 0.021), and low CoQ (p < 0.05) levels. We did not find a significant association between ISSNHL and HCY levels. In the univariate analysis, low levels of CoQ, high levels of total cholesterol, and LDL were found to be significantly associated with ISSNHL. In the multivariate analysis, only high levels of total cholesterol and low levels of CoQ remained significantly associated with a high risk of sudden sensorineural hearing loss. CONCLUSION:: The studies regarding the role of cardiovascular risk factors in ISSNHL are not conclusive. This is the first report regarding the association of ISSNHL and low serum levels of the antioxidant CoQ. Further studies are needed toinvestigate the role of antioxidants, including CoQ, in ISSNHL.
