Hearing loss in Endemic (Balkan) nephropathy.

OBJECTIVE: To evaluate audiograms in dialysed patients with or without diagnose of endemic nephropathy and correlation between parathyroid hormone, endemic nephropathy and auditory thresholds. MATERIALS and METHODS: Case control study. In period of 18 months, series of pure tone audiometry were done in dialysed patients. Patients were divided in four groups depending of endemic nephropathy diagnosis and levels of parathyroid hormone (PTH). Investigations were done on ENT Department General Hospital „Dr. Josip Bencevic“, Slavonski Brod, Croatia. RESULTS: The study included 121 patients. Mean age was 62 years, 52, 9% were males, 47, 1% were females. The average hearing threshold to 1, 5 kHz was 10dB, ranging up to 45dB at 8kHz. Average number of months on hemodialysis was 46, and more than half patients had elevated levels of parathyroid hormone. 51, 2% patients had endemic nephropathy. There was no statistically significance between years of hemodialysis and auditory thresholds. Also, there was no statistically correlation between PTH levels, endemic nephropathy and auditory thresholds. However, there was statistical trend of hearing loss on the right ear for patients with endemic nephropathy, regardless of the values of PTH in relation to renal patients of other etiology. CONCLUSION: There is no statistically significant correlation of hearing loss in patients with endemic nephropathy due to other etiopathogenesis of uremic syndome.
