[Chronic sensory ataxic neuropathy associated with IgM antibody against b-series gangliosides including GD1b]
Abstract:
We described a 62-year-old man with a 10 years history of chronic sensory ataxic neuropathy. His laboratory investigations revealed elevated serum IgM with IgM kappa paraproteinemia, IgM antibody against b-series gangliosides including GD3, GD2, GD1b, GT1b, GQ1b, GQ1b alpha, and high titer of cold agglutinin. The clinical and serological features in our patient were compatible with the diagnosis of CANOMAD (chronic ataxic neuropathy with ophthalmoplegia, M-protein, agglutination, and disialosyl antibodies), proposed by Willison et al. IgM antibody against b-series gangliosides including GD1b appeared to play an essential role in developing autoimmune sensory ataxic neuropathy.
