A 14-year-old boy developed a distinct asymmetrical muscle atrophy and weakness with no sensory disturbance in the lower extremities after enteritis. He had an elevated titre of the IgG antibody against GalNAc-GD1a, but none of the others. A nerve conduction study revealed motor axonopathy. Intravenous immunoglobulin therapy improved the status gradually, with low titres of IgG anti-GalNAc-GD1a.
一名14岁男孩在患肠炎后出现明显的不对称性肌肉萎缩和下肢无力,无感觉障碍。他的抗GalNAc-GD1a IgG抗体滴度升高,但其他抗体均未升高。神经传导研究显示为运动轴索性神经病。静脉注射免疫球蛋白治疗使病情逐渐改善,抗GalNAc-GD1a IgG滴度降低。
