Summary :
Objective: Minimal change nephrotic syndrome (MCNS) is characterized by the onset of NS (Nephrotic Syndrome) without systemic disease, hypocomplementemia, or other serious signs of renal disease. Hearing status is not very well known in MCNS. Our objective was to address this question and to find out remission and relapse periods of the syndrome would affect the hearing of the patients. Methods and Patients: Otologic status of 26 children with clinical MCNS was investigated in relapse and remission periods using audiometry and tympanometry. The pure tones that were obtained at the frequencies 250, 500, 1000, 2000, 4000 and 6000 Hz were noted. Pure tone averages (PTAs) were calculated at 500, 1000, 2000 and 4000 Hz frequencies. Results: In both remission and relapse periods, PTA of the patients did not change and was 13 dB. The frequency specific pure tone results were not significantly different between the right and left ears of the patients as well as between the remission and relapse periods (p>0.05). In the relapsing and remission periods, type A tympanogram was encountered in 86.4% and 92.3% of the ears, respectively. Type B tympanogram was encountered in 11.5% and 3.8% of the ears in the relapsing and remission periods, respectively. Type C tympanogram was encountered in 3.8% of the ears both in the relapsing and remission periods. Differences between the tympanometry results were not significant (p>0.05). Conclusion: MCNS in childhood is not associated with an alteration in the hearing status, both in remission and relapse periods of the disease.
