A Systematic Review on Hearing and Balance in Patients with Chronic Kidney Disease with and Without Hemodialysis

Objective

Exploring the auditory and vestibular manifestations associated with chronic kidney disease (CKD) has been growing in recent years. Understanding these complaints in CKD patients is crucial for comprehensive patient care. This review aimed to investigate the audiological findings and profiles across various stages of CKD and guide for informed decision-making in their management.

Methods

Relevant articles from PubMed, ScienceDirect, EBSCO Medline, SCOPUS, Google Scholar, and Clinical Key were identified for review. The selected articles were published from 2008 to 2023 and written in English language. A total of 41 articles on auditory and vestibular assessments in CKD were eligible for review.

Results

Pure tone audiometry (PTA), immittance audiometry (IA) and otoacoustic emissions (OAEs) were the most commonly employed hearing tests respectively, with a higher frequency of utilization in hemodialysis cases compared to non-hemodialysis ones. Also, vestibular evoked myogenic potentials (VEMPs) emerged as the most popular vestibular test among hemodialysis patients while questionnaires were frequently employed in CKD patients. Moreover, our analysis suggests a potential association between the duration of hemodialysis and the development of tinnitus and vertigo. Abnormalities were also observed in auditory brainstem response (ABR), speech audiometry, central auditory processing tests and videonystagmography (VNG) assessment in hemodialysis and non-hemodialysis patients.

Conclusion

CKD patients, particularly those undergoing hemodialysis, face a higher risk of hearing loss, tinnitus, and vestibular complaints. Performing otoacoustic emissions and vestibular-evoked myogenic potentials along with PTA on CKD patients, regardless of the disease stage is recommended to more effective management of audiovestibular complaints in these population.

High Frequency Hearing Loss in Chronic Renal Disease: A Cross-Sectional Study

Introduction Chronic kidney disease (CKD) patients face multiple complications. One of them is involvement of the auditory system and it deserves more attention than is paid by the current approaches as hearing loss has major repercussions on the quality of life. Early detection can prevent further deterioration of hearing and improve the quality of life of patients suffering from CKD. Material and methods The high frequency (8-18 kHz) audiometry with pure tones was performed in 82 patients with CKD and compared with age and sexes matched healthy control group of 90 patients. Individual ear were used for statistical calculations. Results This study clearly observed that the hearing thresholds for frequencies 8-18 kHz increased in CKD patients when compared to sex and aged matched healthy control group, the thresholds significantly increased in CKD with diabetes mellitus as compared to nondiabetic with CKD. The high frequency thresholds significantly increased in patients on hemodialysis, and were significantly correlated with age, stage of CKD and duration of CKD. Conclusion This study highlights the presence of high frequency (8-18 kHz) hearing loss in patients of CKD. The severity is significantly correlated with age, stage and duration of CKD.

Audiovestibular functions in chronic kidney disease in relation to haemodialysis

Background

Several studies have reported that the audiovestibular system is affected in patients with chronic kidney disease.

Objective

This study aimed to investigate how the audiovestibular system is affected in patients with various stages of chronic kidney disease.

Methods

Sixty participants were divided into three groups: group 1 – controls; group 2 – chronic kidney disease patients receiving conservative treatment; and group 3 – chronic kidney disease patients undergoing regular haemodialysis. Assessments included: standard and high-frequency audiometry and otoacoustic emissions testing, oculomotor tests, and combined vestibular-evoked myogenic potentials testing.

Results

Fifty per cent of group 2 and 60 per cent of group 3 had bilateral sensorineural hearing loss. High-frequency pure tone audiometry showed reduced detectability and higher thresholds at 12 kHz and 16 kHz in patients than in controls. Otoacoustic emissions, tracking, optokinetic and combined vestibular-evoked myogenic potential tests showed abnormal results in chronic kidney disease cases.

Conclusion

Both the auditory and vestibular pathways are affected in different stages of chronic kidney disease. High-frequency pure tone audiometry, otoacoustic emissions and combined vestibular-evoked myogenic potentials could be performed routinely in patients with chronic kidney disease, regardless of the disease stage.
