[Otoneurologic abnormalities in insulin-dependent diabetes].
OBJECTIVE
To assess the auditory and vestibular function in patients with diabetes.


METHODS
We studied and followed for three years, 10 patients (6 females) of 20.6 years of age (SD 5.5 years), with insulindependent diabetes mellitus of 9.5 years (SD 3.7 years). The patients were selected for having peripheral neuropathy without prolipherative retinopathy and otologic disease or individual factors which could cause neurootologic symptoms. Their glomerular filtration rate and renal plasma flow were 150 mL/min (SD 50) and 543 mL/min (SD 113).


RESULTS
Initially all patients had normal audiologic responses, including auditory brainstem responses, but had abnormally and simetrically diminished horizontal vestibulo-ocular responses. A year later one patient had vertigo and asymmetric vestibulo-ocular responses. In the third year, another patient showed similar abnormalities and a third one showed sensorineural hearing loss.


CONCLUSIONS
Our results suggest that patients with insulindependent diabetes mellitus may suffer neuro-otological deterioration.
