It is critical to screen patients with rheumatoid arthritis (RA) for hearing impairment
RA is the commonest autoimmune arthritis affecting 1% of the population. Despite its main articular manifestations, RA can involve extra-articular organs including the auditory system.
Environmental factors for instance smoking, alcohol and noise can deteriorate the condition. Passive smokers are also at risk of HI. Long-term exposure to alcohol affects hearing in RA, causing harmful effects on the cochlear function.
Results of pure tone audiometry revealed that RA patients have high prevalence of HI for all frequencies.Transiently Evoked Otoacoustic Emissions (TEOAEs) test has been used widely to evaluate cochlear function, and is capable of detecting various amounts of decreases in RA patients at an early stage of the disease.
Treatment of HI in RA is empirical. Oral steroids and intensifying Disease-Modifying Antirheumatic Drugs might be an option. Anti-oxidants (eg. vitamin E) may play a protective role for the inner ear. Regular audiometric test and TEOAEs should be performed. Patients will also benefit from the cessation of smoking and alcohol. Like other causes of HI in healthy individuals, HI in RA can also be managed by use of different types of hearing aids and implantable devices.
