title: [The Guillain-Barré syndrome].
abstract: A clinicomorphological study was conducted in 11 patients with severe forms of Guillain-Barré syndrome (GBS) at different periods of the disease. Five postmortem cases of GBS were investigated. In all the cases there was a multifocal loss of myelin in the peripheral nervous system with axon degeneration of various degree. Macrophages always took part in demyelination sometimes followed by lymphocytic infiltration. Ultrastructural investigation of nerve biopsies from 6 patients with GBS showed macrophage-associated demyelination with little or no lymphocytic infiltration. It is likely that axonal damage revealed in the biopsies and at the autopsies occurs as secondary consequence of demyelination.
