Journal of the Peripheral Nervous System 15:185–195 (2010) EFNS/PNS PDN GUIDELINE European Federation of Neurological Societies/Peripheral Nerve Society Guideline* on management of paraproteinemic demyelinating neuropathies. Report of a Joint Task Force of the European Federation of Neurological Societies and the Peripheral Nerve Society – first revision Joint Task Force of the EFNS and the PNS† Abstract The aim of this guideline is to update the 2006 EFNS/PNS guideline on management of patients with a demyelinating neuropathy and a paraprotein (paraproteinemic demyelinating neuropathy [PDN]) by review of evidence and expert consensus. In the absence of adequate evidence, the panel agreed on good practice points: (1) patients with PDN should be investigated for a malignant plasma cell dyscrasia; (2) a monoclonal gammopathy of undetermined significance is more likely to be causing the neuropathy if it is immunoglobulin (Ig)M, anti-neural antibodies are present, and the clinical phenotype is chronic distal sensory neuropathy; (3) patients with IgM PDN usually have predominantly distal sensory impairment, prolonged distal motor latencies, and often anti-myelin-associated glycoprotein antibodies; (4) IgM PDN may respond to immunomodulatory therapies. Their potential benefit should be balanced against possible side effects and the usually slow disease progression; (5) IgG and IgA PDN may be indistinguishable from chronic inflammatory demyelinating polyradiculoneuropathy; and (6) Polyneuropathy, Organ
