Immunoglobulin M (IgM)-Anti-myelin-associated-glycoprotein(MAG) Peripheral Neuropathy Study

Immunoglobulin M (IgM)-Anti-myelin-associated-glycoprotein(MAG) Peripheral Neuropathy Study: From Proper Assessment to Trial Needs - IMAGiNe Study-Lyon/Bicêtre

Important: This information is not medical advice. Talk to your doctor about whether a clinical trial is right for you.

About This Trial

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.

Who May Be Eligible (Plain English)

Who May Qualify: - fulfilling the international criteria for the diagnosis Immunogloblin M (IgM) monoclonal gammopathy, with anti-myelin-associated-glycoprotein (MAG) antibodies, and peripheral neuropathy. - age of 18 years or older followed in neuromuscular department of Lyon; - willing to sign a consent form given by the participant Who Should NOT Join This Trial: - concomitant diseases possibly interfering with peripheral nerve and function, as well as physical functioning, such as diabetes, renal insufficiency, (prior) treatment with chemotherapy for diseases other than their Immunogloblin M (IgM) monoclonal gammopathy associated peripheral neuropathy, history of hereditary neuropathy, vitamin deficiency, connective tissue disorder, hepatitis B and C and human weakened immune system virus (HIV) infection, alcohol abuse (more than 5 International Units(IU)/day); - an active malignancy with poor prognosis, undergoing treatment aside from monoclonal gammopathy associated peripheral neuropathy; - pregnant; - the use of any medication that may cause peripheral nerve function Always talk to your doctor about whether this trial is right for you.

Treatments Being Tested

OTHER

Clinical examination and patients' questionnaires regarding activity and participation (preliminary Immunogloblin M (IgM)-Rasch-built overall Disability Scale (RODS), and finalized IgM-RODS)

Rasch-built overall Disability Scale (RODS) is a disease-specific, patient-based, linearly weighted scale that captures activity and social participation limitations to detect activity limitations in patients with Immunogloblin M (IgM) anti-myelin-associated-glycoprotein peripheral neuropathy. For this study, the preliminary RODS is a 146 item patient-reported outcome instrument that assesses activity and social participation limitation. Rasch Measurement Methods examine the extent observed data (patients' actual responses to scale items) accord with predictions of those responses from a mathematical model.
