Resumen

Exponemos dos casos de presentación atípica de síndrome de Cogan en sendos individuos de 47 y 56 años de edad. En ambos se detecta la sintomatología característica del síndrome (queratitis intersticial, hipoacusia neurosensorial y vértigo), pero la asociación de trastornos generales y el inicio del cuadro por su deterioro audiovestibular los hacen infrecuentes. Los dos casos evidenciaron elevaciones en la VSG y niveles de inmunoglobulinas, y títulos positivos de factor de reumatoide y autoanticuerpos inespecíficos. Mediante un test de Western-blot pudieron determinarse anticuerpos contra antígenos clocleares de distinto peso molecular, siendo común el de 68 KD. El tratamiento de metil-prednisolona no evitó nuevas recidivas oftálmicas y auditivas en uno de los dos pacientes.

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.
