We describe a patient with autoimmune insulin-dependent diabetes whose original symptoms of trunk stiffness and rigidity of the abdomen were followed three years later by a pancerebellar syndrome. An autoantibody (autoAb) against GABAergic neurons was found in the patient's serum and cerebrospinal fluid (CSF); on Western blot, this autoAb recognized a 64-kDa antigen of cerebellar protein. The detection of this antibody in a case with ataxia suggests that a spectrum of different neurological diseases may be observed in patients harbouring anti-GABAergic neuron autoAb and supports the concept that factors other than autoAb contribute to the clinical presentation of these disorders.

Abstract
We describe a patient with autoimmune insulin-dependent diabetes whose original symptoms of trunk stiffness and rigidity of the abdomen were followed three years later by a pancerebellar syndrome. An autoantibody (autoAb) against GABAergic neurons was found in the patient's serum and cerebrospinal fluid (CSF); on Western blot, this autoAb recognized a 64-kDa antigen of cerebellar protein. The detection of this antibody in a case with ataxia suggests that a spectrum of different neurological diseases may be observed in patients harbouring anti-GABAergic neuron autoAb and supports the concept that factors other than autoAb contribute to the clinical presentation of these disorders.Pubblicazioni consigliate
