Audiological findings in elderly patients with chronic renal failure

The audiological results of 46 patients (m/f 27/19, mean age; 57.4 mp 11.1) with chronic renal failure (CRF) undergoing dialysis were compared with those of an age—gender—matched control group (n=25). Mean pure tone average from 0.5 to 8 kHz was about 15 dB higher in CRF patients than in control subjects. The ABR parameters of the test group were then contrasted with those recorded in a second control group (n=47, m/f 26/21, mean age: 56.1 ± 11.4) matched by age, gender and degree of hearing loss (HL). After assessing the normality of the groups by the usual criteria, using the data of a sample of normal young adults, the ABR were found to be abnormal in 23.9% of the controls and in the 39.13% of the CRF patients. Wave V, I—III, III—V I—V delays were significantly shorter in the females of the control group; in the CRF group, only the V and the I—V delays were shorter in females. The only age—dependent effect was found in the CRF sample, in which older patients had significantly longer I—III IPLD. The deg...
