UNLABELLED
Autoantibodies against myelin oligodendrocyte glycoprotein (MOG-IgG) have been reported in patients with inflammatory central nervous system disorders including isolated optic neuritis (ON). We compared our MOG-IgG ON patients with multiple sclerosis (MS) patients presenting with ON.
METHODS AND RESULTS
Among the total of 38 patients with optic neuropathies, six patients with isolated ON were MOG-IgG positive and eight patients with ON fulfilled the diagnostic criteria for MS. All MS patients were negative for MOG-IgG using a cell-based assay. When compared with the MS group, the MOG-IgG patients were older (mean 47 years), more frequently male (ratio 2:1) and had a higher frequency of bilateral and/or recurrent ON. The brain magnetic resonance imaging of all MOG-IgG positive patients was normal or had only unspecific white matter T2 lesions.
CONCLUSION
These findings suggest that MOG-IgG is a biomarker of an inflammatory demyelinating CNS disease distinct from MS.
未标注
在包括孤立性视神经炎（ON）在内的炎症性中枢神经系统疾病患者中，已报告存在抗髓鞘少突胶质细胞糖蛋白（MOG-IgG）自身抗体。我们将我们的MOG-IgG阳性视神经炎患者与表现为视神经炎的多发性硬化症（MS）患者进行了比较。
方法与结果
在总共38例视神经病变患者中，6例孤立性视神经炎患者MOG-IgG呈阳性，8例视神经炎患者符合MS诊断标准。所有MS患者采用基于细胞的检测方法检测MOG-IgG均为阴性。与MS组相比，MOG-IgG阳性患者年龄较大（平均47岁），男性比例更高（比例为2:1），双侧和/或复发性视神经炎的发生率更高。所有MOG-IgG阳性患者的脑磁共振成像正常或仅有无特异性的白质T2病变。
结论
这些发现表明，MOG-IgG是一种不同于MS的炎症性脱髓鞘性中枢神经系统疾病的生物标志物。
