Abstract
Background: Disturbance in the nervous system of patients with chronic kidney diseases (CKD(, including uremic neuropathy, may lead to changes in the auditory processing of these patients. The impairment of auditory processing results in communication, social and emotional problems in the life. Accordingly, in this study, communication abilities and speech perception in noise in CKD patients are analyzed to identify the disorders more rapidly.
Methods: In this cross-sectional/comparative study, 30 CKD patients and 29 normal adults aged 20-55 years with normal peripheral hearing were randomly selected and the consonant-vowel (CV) test was performed with 5 signal-to-noise ratios (SNR) and silence, and speech, spatial and qualities of hearing scale questionnaire (SSQ) was applied to them with three subscales. The scores of the two groups were compared with the Mann-Whitney U test.
Results: In both groups, the increase in noise led to a decrease in the consonant-vowel recognition scores. However, the normal group outperformed the patients at all levels. Patients in three subscales of the SSQ obtained a lower score than the normal group, but this difference was not statistically significant.
Conclusions: The chronic renal failure reduces speech perception abilities in noise, and this finding indicates the auditory neurological involvement in CKD. Although the self-assessment by patients did not reveal any speech processing disability, for the early diagnose of hearing disability and mitigation of the consequences of hearing disability, it is recommended to periodically and regularly control the central hearing of patients and take proper rehabilitation measures if a disability is diagnosed.
