Abstract

The presence of anti-glycolipid specific antibodies have been found to be associated with acute and chronic immune-mediated peripheral neuropathies. Recently a number of anti-glycolipid antibody assays have became commercially available. In this study we established specific anti-glycolipid antibody profiles in a series of sera by the Dotzen Ganglio Profile antibodies. This kit screens for the simultaneous detection of ten anti-glycolipid antibodies against GM3, GM2, GM1, GD3, GD1a, GD1b, GT1a, GT1b, GQ1b gangliosides and sulfatides of the IgM and IgG classes. Sera from 89 patients with acute and chronic neuropathies were selected in a well-characterized cohort of banked sera with anti-glycolipid antibody profiles identified by in-house immunodot assay. Serum from 52 clinical variants of Guillain-Barré syndrome with IgG autoantibody profiles and 37 chronic acquired peripheral neuropathy with IgM autoantibody profiles were tested. The assay correctly identified with good agreement 50 of 52 IgG antibody profiles and 32 of 37 IgM antibody profiles. The assay compared well with in-house immunodot assay. It is easy to screen 10 crossreacting glycolipid antibodies to establish specific antibody profiles to define different subgroups of immune-mediated peripheral neuropathies for classification and immune management.
