Five patients with neuropathy and IgM M-proteins that reacted with myelin-associated glycoprotein (MAG) were treated for 10 to 20 months with cytostatic agents. In 2 patients, a decrease in serum M-protein and in anti-MAG IgM levels coincided with a progressive improvement of neuropathy. No clinical improvement and no decrease of anti-MAG IgM were observed in the other patients. The close relationship between the decrease of anti-MAG M-proteins and clinical improvement in these patients supports the pathogenetic role of the M-protein in the neuropathy.
5例患有神经病变且免疫球蛋白M(IgM)与髓鞘相关糖蛋白(MAG)发生反应的患者接受了10至20个月的细胞毒性药物治疗。其中2例患者血清M蛋白和抗MAG IgM水平降低,同时神经病变逐渐改善。其他患者未观察到临床改善,抗MAG IgM也未降低。这些患者中抗MAG M蛋白降低与临床改善之间的密切关系支持了M蛋白在神经病变中的致病作用。
