JAMA Neurol:MOG-IgG脊髓炎特征研究

2018-12-24 zhangfan MedSci原创

MOG-IgG相关疾病的早期表现为脊髓炎,其中最常见的为急性弛缓性脊髓炎,疑似MOG-IgG人群因接受相应的临床及影像学检查

识别髓鞘少突胶质细胞糖蛋白自身抗体型(MOG-IgG) 患者临床特点,是早期准确诊断和治疗的关键。近日研究人员就MOG-IgG型脊髓炎的临床、影像学及预后特点进行考察,并与水通道蛋白-4-IgG(AQP4-IgG) 脊髓炎和多发性硬化(MS)进行比较。

54名MOG-IgG阳性脊髓炎患者参与研究,入选标准包括临床脊髓炎症状、MOG-IgG阳性以及病历可获得,同时招募46名AQP4-IgG以及26名MS患者。研究的主要终点包括Rankin评分、辅助行走需求以及脊柱磁共振成像。

MOG-IgG患者平均年龄25岁,女性占44%。29例(54%)为孤立性横脊髓炎患者,10例(19%)为病毒/病毒后急性弛缓性脊髓炎患者。1名患者出现脑脊液寡克隆带增高(3%)。研究平均随访24个月,32名患者多次反复出现视神经炎、横向脊髓炎或急性播散性脑脊髓炎复发。相比于AQP4-IgG和MS,MOG-IgG患者前驱症状和并发急性播散性脑脊髓炎显著。磁共振显示,MOG-IgG患者 T 2信号异常局限于灰质,增强不明显;MOG-IgG 与AQP4-IgG纵向广泛T2病变无显著差异,但未见于MS患者;MOG-IgG与MS患者多发性脊髓病变和圆锥受累较多;约1/3的MOG-IgG 和AQP4-IgG患者行动依赖轮椅,但大部分MS患者不需要,MOG-IgG患者的预后优于AQP4-IgG患者。

MOG-IgG相关疾病的早期表现为脊髓炎,其中最常见的为急性弛缓性脊髓炎,疑似MOG-IgG人群因接受相应的临床及影像学检查。
