There is no international consensus regarding how to assess and treat patients with immunoglobulin M (IgM)-anti-myelin-associated-glycoprotein (MAG) monoclonal gammopathy associated peripheral neuropathy. The purpose of the IMAGiNe study-Lyon/Bicêtre is to prospectively collect standardized clinical data of 25 patients with IgM-anti-MAG monoclonal gammopathy associated peripheral neuropathy in order to participate in the international IMAGiNe Study. The main objective is to describe in detail the various clinical subtypes, clinical course, treatment responses, antibody titers of IgM-anti-MAG monoclonal gammopathy associated peripheral neuropathy using a variety of outcome measures. The obtained observational data will allow the construction of an IgM monoclonal gammopathy associated peripheral neuropathy-specific Rasch-built overall Disability Scale (RODS) that should fulfill all modern clinimetric requirements, including cross-cultural validity. The coordinating centers for the IgM-RODS construction will be the Maastricht University Medical Center and University Medical Center Utrecht, both in the Netherlands.
