Abstract:

Abstract We show two atypical Cogan’s syndrome cases in forty - seven and fifty - six years old individuals . Characteristical symptoms of the syndrome were detected in both ( interstitial keratitis , sensorineural deafness and vestibular dysfunction ) , but they could be considered as unusual because of the association of sistematic symptoms and an onset with hearing loss . In both cases there was an increase in erythrosedimentation rate and immunoglobulins leveles , as well as high titles for rheumatoid factor and non - specific autoantibodies . By means of a Western - blot technique , several choclear antibodies with distinct molecular weight were detected , but the 68 KD appeared in both . Metil - prednisolone treatmen did not avoid ocular and auditive reactivation in ne of the patients .
