Sudden-Onset Sensorineural Hearing Loss and Tinnitus in a Patient With Rheumatoid Arthritis: A Case Report and Literature Review.

Rheumatoid arthritis (RA) can affect the auditory system either as a direct complication of the disease course or secondary to medication adverse effects. Rheumatoid arthritis-induced autoimmune inner ear disease can present as tinnitus, conductive hearing loss, sensorineural hearing loss (SNHL), or mixed. According to previously published articles, SNHL is the most common hearing loss in RA. Age, smoking, noise exposure, and alcohol may affect the disease progression. Here, we present a case of a 79-year-old female who presented to the rheumatology clinic with complaints of abrupt onset bilateral hearing loss with associated tinnitus; pure tone audiometry confirmed sensorineural hearing loss. Her tinnitus resolved completely, and her hearing improved significantly after treatment with steroids and leflunomide. Based on this case and previous literature, we conclude that rheumatoid arthritis is the cause of SNHL in our patient. Appropriate and timely medical interventions have been reported to improve the prognosis of hearing impairment in rheumatoid arthritis patients. Our case highlights the need to have a high index of suspicion of rheumatoid arthritis-induced autoimmune inner ear disease in an elderly patient presenting with sudden-onset hearing impairment and the importance of prompt referral to a rheumatologist.
