Abstract

Guillain-Barré syndrome (GBS) is an acute immune-mediated disorder of the peripheral nervous system and a triggering infectious event is often reported in the weeks before the disease onset. Influenza viruses have been associated with Guillain-Barré syndrome (GBS), both after infection and, in rare cases, after vaccination. However, GBS has rarely reported to be a neurological complication of the recent pandemic influenza A(H1N1) 2009 virus infections. Here we describe the case of a young man, who developed acute severe motor inflammatory demyelinating polyradiculoneuropathy during influenza A(H1N1)2009 infection. Peculiar features are the findings of a mutated haemagglutinin gene (D222E variant), which has never previously been associated with neurological involvement, and the almost simultaneous appearance of respiratory infectious and immune-mediated neurological symptoms. Moreover we review the clinical presentation, laboratory findings and outcome of influenza-related GBS.
