Abstract
IgM antibodies against gangliosides and their complexes were studied in sera from 54 patients with polyneuropathy and IgM monoclonal gammopathy (IgM-PNP) without anti-MAG antibodies. Anti-ganglioside antibodies were found in 19 (35%) patients. Five (9%) patients had antibodies against ganglioside complexes. IgM antibodies against gangliosides activated complement in vitro. Light chain usage was restricted to kappa or lambda in most, but not all patients. In conclusion, anti-ganglioside antibodies in IgM-PNP are common, display pathogenic properties and do not always arise from a monoclonal B cell proliferation.Entities:
