Аннотация
PURPOSE: Autoimmune encephalitis is an inflammatory disorder of the brain that may be associated with different neuronal antibodies. Recently, an increasing number of valuable autoantibodies have been identified, including GABAAR antibodies, which appear to be associated with a severe form of encephalitis with refractory status epilepticus. We report here on a patient with encephalitis associated with GAD65 and GABAAR antibodies, an entity that remains an understudied topic, with an unanticipated clinical presentation and we describe the longitudinal follow-up.
METHODS: We report a case of encephalitis associated with GAD65 and GABAAR antibodies; we describe clinical and paraclinical features and the longitudinal follow-up.
RESULTS: Our case presented with dysgueusia, dysosmia and episodes of hyperventilation that evolved into a refractory status epilepticus. Multiple anticonvulsant drugs were required. An aggressive immunotherapy was associated with a relative favorable outcome, in regard of epilepsy and cognitive functions. However, a relapse occurred and a full recovery was not observed at the last follow-up visit. There was no correlation between GAD65 antibodies titers and disease activity.
CONCLUSION: Autoimmune encephalitis associated with GABAAR and GAD65 antibodies might be a severe and refractory disease. The appropriate treatment is currently unknown for those patients.
