Detection of hearing loss in rheumatoid arthritis patients using extended high frequency audiometry: Is it related to disease activity and severity?

Abstract Aim of the work To evaluate audiological characteristics in rheumatoid arthritis (RA) patients compared with controls using extended high frequency audiometry and analyze their correlations with RA activity and severity to identify patients at higher risk of hearing loss. Patients and methods The study was carried out on 95 RA patients and 100 controls. Every subject underwent pure tone audiometry (PTA) from 250 through 8000 Hz, speech audiometry and extended high frequency audiometry (EHFA) from 10,000 to 20000 Hz. Disease activity score (DAS28) and RA medical records-based index of severity (RARBIS) were assessed. Results Patients were 85 females and 10 males with age mean 46.5 ± 1.1 years and disease duration of 9.57 ± 0.61 years. The hearing thresholds (HT) of patients were significantly higher than those of controls at all PTA (p  Conclusion Bilateral symmetrical sensorineural hearing loss (SNHL) is significantly more frequent in RA patients compared to control. EHFA is valuable test to detect HL in patients with RA. Older age, longer disease duration, higher disease activity and severity are important factors for the development of HL in RA.
