Detection of anti-ganglioside antibodies in Guillain-Barre syndrome.
نویسنده
چکیده
Sera from 40 patients with Guillain-Barré syndrome (GBS), including the subtypes acute inflammatory demyelinating polyneuropathy (AIDP), acute motor axonal neuropathy (AMAN), acute motor and sensory axonal neuropathy (AMSAN), and Miller Fisher syndrome (MFS) were examined for the presence of anti-ganglioside antibodies using the ganglioside agglutination assay, and the enzyme-linked immunosorbent assay (ELISA). In the ELISA system, sera were tested for IgM and IgG antibodies to GM1, GM2, GD1a, GD1b, GT1b, and GQ1b gangliosides. Antibodies to gangliosides were detected in 21 (53%) of the GBS patients by agglutination assay and in 17 (43%) of the patients by ELISA. Some of the sera reacted with more than one ganglioside. Antibodies were not found in the control sera that were studied. The agglutination assay may be useful for rapid screening of GBS sera for antibodies to multiple gangliosides.

متن کاملThe crucial role of Campylobacter jejuni genes in anti-ganglioside antibody induction in Guillain-Barre syndrome.
Molecular mimicry of Campylobacter jejuni lipo-oligosaccharides (LOS) with gangliosides in nervous tissue is considered to induce cross-reactive antibodies that lead to Guillain-Barre syndrome (GBS), an acute polyneuropathy. To determine whether specific bacterial genes are crucial for the biosynthesis of ganglioside-like structures and the induction of anti-ganglioside antibodies, we character...
متن کاملMiller Fisher syndrome is associated with serum antibodies to GQ1b ganglioside.
A recent report described serum anti-GQ1b ganglioside antibodies in Miller Fisher syndrome (MFS), a clinical variant of Guillain-Barré syndrome (GBS). Four consecutive cases of MFS all had high titre anti-GQ1b antibodies which were absent from all control sera including those of patients with GBS.
