Background: Hearing impairment (HI) is classified into conductive, sensorineural, and mixed types. Sensorineural hearing loss in autoimmune diseases (AD), although not uncommon, is underdiagnosed. Autoimmune diseases may affect the vestibulocochlear system at variable degrees which is usually underdiagnosed due to unidentified specific antigens. Objectives: to assess audiovestibular system in a cohort of patients to aid in early recognition and management of a vital overlooked aspect of such comorbidity. Subjects and Methods: A total of ninety-eight adult patients complaining of different systemic autoimmune rheumatic diseases followed-up at outpatient rheumatology clinics were enrolled in this cross-sectional study. Patients were categorized into three sub-groups: rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and Behçet's disease (BD). Clinical, laboratory, audiological and vestibular assessment of disease activity among different groups was done. Results: Pure tone audiometry (PTA) values showed significantly increased prevalence of hearing loss in our AD patients compared to healthy control group (P <0.000). Regarding vestibular assessment, pathological saccades were discovered using the vHIT, particularly in horizontal canals. The patient's gain values were slightly lower than the control group; however, gain and gain asymmetry differed significantly in a few canals. Disease duration significantly correlated with hearing thresholds at high frequency in RA and SLE patients. DAS-28 in RA patients significantly correlated with hearing thresholds, however SLEDAI in SLE didn't reveal any correlation. Conclusions: Early audiovestibular screening in patients with autoimmune rheumatic diseases should be considered, especially in those with long disease duration as neglected impairment is prevalent.
Background: Recently there is growing interest for inner ear involvement in systemic autoimmune diseases. Several studies showed inflammatory cells in the inner ear, describing the presence of resident cochlear macrophages in animal models and the recruitment of inflammatory macrophages to the cochlea. (1) Method: 16 rheumatoid arthritis patients were enrolled in this study. Audiological assessment was done using pure tone audiometry (PTA). Vestibular assessment for lateral semicircular canal was done by video head impulse test (VHIT). Results: 50% of rheumatoid arthritis patients were discovered to be suffering of hearing loss of all types and degrees detected by pure tone audiometry, VHIT was normal in all patients. Conclusion: Hearing impairment is not uncommon finding in rheumatoid arthritis patients. It can have a negative impact on a patient's quality of life. So, audiological assessment and follow up are necessary for rheumatoid arthritis patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
