          Abstract

          Background: Diagnostic criteria for the Guillain-Barré syndrome (GBS) have been available since 1978. Since then, several variants have been described. More recently, a distinction has been made between pure motor forms, severe sensory forms, primary axonal and primary demyelinating varieties. Associations of clinical characteristics, and specific infections and the presence of antiganglioside antibodies have been found. For further studies on GBS, it is therefore necessary to reconsider the available diagnostic criteria and add additional criteria for subclassification. Methods: A panel of (20) experts was formed. The literature representing the recent developments in GBS subclassification was reviewed. Following a consensus protocol, diagnostic and classification criteria were formulated. Results: The diagnosis of GBS can usually be made on clinical characteristics. A schedule for subclassification has been made to cover also the clinical variants in a systematic manner.

          Anti-GD1a antibody is associated with axonal but not demyelinating forms of Guillain-Barré syndrome.

          Immunopathological studies suggest that the target of immune attack is different in the subtypes of Guillain-Barré syndrome (GBS). In acute motor axonal neuropathy (AMAN), the attack appears directed against the axolemma and nodes of Ranvier. In acute inflammatory demyelinating polyneuropathy (AIDP), the attack appears directed against a component of the Schwann cell. However, the nature of the antigenic targets is still not clear. We prospectively studied 138 Chinese GBS patients and found that IgG anti-GD1a antibodies were closely associated with AMAN but not AIDP. With a cutoff titer of greater than 1:100, 60% of AMAN versus 4% of AIDP patients had IgG anti-GD1a antibodies; with a cutoff titer of greater than 1:1,000, 24% of AMAN patients and none of the AIDP patients had IgG anti-GD1a antibodies. In contrast, low levels of IgG anti-GM1 antibodies (> 1:100) were detected in both the AMAN and the AIDP forms (57% vs 35%, NS). High titers of IgG anti-GM1 (>1:1,000) were more common in the AMAN form (24% vs 8%, NS). Serological evidence of recent Campylobacter infection was detected in 81% of AMAN and 50% of AIDP patients, and anti-ganglioside antibodies were common in both Campylobacter-infected and noninfected patients. Our results suggest that IgG anti-GD1a antibodies may be involved in the pathogenesis of AMAN.

            Severe axonal degeneration in acute Guillain-Barré syndrome: evidence of two different mechanisms?

            Four cases of severe acute Guillain-Barré syndrome (GBS) characterized by severe axonal degeneration are presented. All had electrically inexcitable motor nerves as early as 4 days after onset. The disease was rapid in onset and the residual disability was severe. Two different types of pathology were seen. Nerve biopsies in 3 cases showed severe axonal degeneration without inflammation or demyelination. Autopsy in one of these cases showed that the dorsal and ventral roots were also significantly affected. These cases illustrate the primary axonal form of GBS. Nerve biopsy in the fourth case at day 15 showed marked inflammation and demyelination with axonal degeneration. Contralateral nerve biopsy at day 75 showed almost complete loss of axons. This case illustrates another type of axonal degeneration, that which occurs secondary to inflammation and demyelination.
