Obinutuzumab, a potent anti–B-cell agent, for rituximab-unresponsive IgM anti-MAG neuropathy
We describe clinical response and autoantibody changes after treatment with obinutuzumab (Gazyva), a new generation of humanized anti-CD20 monoclonal antibodies, in 2 patients with anti-MAG neuropathy who continued to worsen despite multiple courses of rituximab. Obinutuzumab, approved for chronic lymphocytic leukemia (CLL), exerts greater peripheral and lymphoid B-cell depletion and might be m...
متن کاملBinding specificity of anti-HNK-1 IgM M-protein in anti-MAG neuropathy: possible clinical relevance.
Anti-myelin-associated-glycoprotein (MAG) neuropathy is an intractable autoimmune polyneuropathy. The antigenic region of MAG is the human natural killer-1 (HNK-1) carbohydrate. We and others previously suggested that the extension of antibody reactivities to HNK-1-bearing proteins other than MAG was associated with treatment resistance, without statistical analyses. In this study, we establish...
متن کاملPeripheral neuropathy associated with monoclonal IgM anti-Pr2 cold agglutinins.
A patient with a chronic, large fibre sensory neuropathy had an immunoglobulin M lambda monoclonal paraprotein reactive at titres in excess of 1/10(5) with NeuNAc(alpha 2-8)NeuNAc(alpha 2-3)Gal configured disialosyl groups present on the gangliosides GD1b, GT1b, GQ1b, and GD3. The paraprotein showed weaker reactivity with GD1a, GM3, and LM1 but no reactivity with GM2, GM1, or asialo-GM1. In add...
متن کاملLong-term prognosis of neuropathy associated with anti-MAG IgM M-proteins and its relationship to immune therapies.
Many data point to a pathogenetic role for IgM antibodies to the myelin-associated glycoprotein (MAG) in the neuropathy associated with IgM monoclonal gammopathy, supporting the use of immune therapies in affected patients. Almost 50% of patients have been reported to improve with these therapies, but the effect of treatment on the long-term prognosis of the neuropathy remains unclear. We analy...
متن کاملIgM monoclonal gammopathy and neuropathy in two siblings.
A sister and a brother with a progressive mixed axonal and demyelinating polyneuropathy were found to have a monoclonal IgM gammopathy of kappa and lambda type, respectively. Sural nerve and cutaneous nerve specimens obtained by biopsy showed deposits of IgM on myelin sheets. Sera from both patients contained antibodies directed to bovine peripheral nerve myelin as determined by ELISA technique...
