Serum Renin Levels in Sudden Sensorineural Hearing Loss

Abstract

Objective: The aim of this study was to investigate the serum renin levels of patients with idiopathic sudden sensorineural hearing loss (ISSNHL). Material and Methods: Twenty-four patients with ISSNHL and 24 asymptomatic healthy volunteers were included in the study. Subjects underwent pure-tone audiometry and serum renin levels were measured. Results: There were 14 women (mean age:42.35 ± 9.53) and 10 men (mean age:43.8 ± 6.87) in the patient group. There were 14 women (mean age:42.4 ± 4.7) and 10 men (mean age:41.4 ± 4.59) in the control group. ISSNHL was detected on the right side in 13 patients and on the left side in 11 patients. Serum renin levels of the patients and controls were 788.01 ± 327.8 and 282.37 ± 107.73 pg/mL, respectively. The serum renin levels were found to be significantly higher in the patient group compared to the control group ( P ≤ .001). There was a statistically significant strong positive correlation between serum renin level and the severity of hearing loss ( r = 0.77; P = .001). Conclusion: Serum renin levels of patients with ISSNHL were higher than controls. There was a statistically significant strong positive correlation between serum renin level and the severity of hearing loss.
