Abstract

Neuropathy has been frequently reported in patients with monoclonal gammopathy, particularly those with monoclonal gammopathy of undetermined significance (MGUS). While the neuropathy associated with IgM-MGUS is well characterized and is often associated with a reactivity of the monoclonal protein with neural antigens, the relationship between the neuropathy and IgG and IgA MGUS is less clear. We review here the clinical, electrophysiological and pathogenetic features of neuropathies associated with IgG and IgA M-proteins in order to determine whether they represent distinct clinical entities and, most importantly, whether the finding of an IgG or IgA monoclonal gammopathy in a patient with neuropathy should led to different diagnostic or therapeutical approaches. This review will mainly focus on neuropathies associated with MGUS since the disclosure of a malignant monoclonal gammopathy, including multiple or osteosclerotic myeloma, lymphoma or primary amyloidosis, in a patient with neuropathy usually divert the therapeutical decisions to the hematologist for an appropriate therapy of the underlying lifethreatening condition.
