A patient with polyneuropathy due to Waldenström's macroglobulinemia (WM) was treated successfully with chlorambucil and prednisone. Before therapy, 60% of peripheral lymphocytes were B cells, the nerve had IgM-bearing B-cell infiltrates, and the circulating IgM had antibody-binding activity to autologous and homologous nerves. Neurologic improvement, sustained for 4 years, began 3 months after therapy and coincided with the return to normal of bone marrow and circulating B cells. Binding of IgM to autologous and homologous nerves persisted after therapy, suggesting that not the IgM alone but other B-cell factors, possibly complexed to IgM, may have been responsible for the nerve damage.
