摘要:

目的 探讨抗富亮氨酸胶质瘤失活蛋白1(LGI1)抗体相关脑炎的临床特点。方法与结果 2016年9月至2018年4月共诊治6例抗LGI1抗体相关脑炎患者,临床表现为认知功能障碍(6例)、癫发作(4例)、精神行为异常(3例)、睡眠障碍(5例)、自主神经功能障碍(3例),病程中可伴有低钠血症(4例)。脑电图异常较为常见(4例)。头部MRI显示炎症性病变主要累及海马、颞叶内侧(3例)。血清和脑脊液LGI1抗体检测(间接免疫荧光法)双阳性者4例,单纯血清或脑脊液LGI1抗体阳性者分别为6和4例。采用激素和(或)免疫球蛋白治疗,随访6~24个月无一例死亡;其中3例遗留记忆力下降、1例面-臂肌张力障碍发作、2例低钠血症、1例睡眠障碍。。结论 抗LGI1抗体相关脑炎以认知功能障碍、癫发作、睡眠障碍、低钠血症为临床特征,对免疫治疗有效,预后相对良好。

Abstract:

Objective To explore the clinical characteristics of anti-leucine-rich glioma-inactivated 1 (LGI1) antibody-related encephalitis. Methods and Results Clinical data of 6 patients with anti-LGI1 antibody-related encephalitis from September 2016 to April 2018 were analyzed retrospectively. The clinical manifestations of 6 cases were lognition disorders in 6 cases, seizures in 4 cases, behavioral changes in 3 cases, sleep disorders in 5 cases and autonomic nervous system abnormality in 3 cases. Hyponatremia (4 cases) could be presented. Abnormal EEG (4 cases) was often seen. Brain MRI showed abnormal signals in 3 cases, mainly involved hippocampus and medial temporal lobe. Indirect immunofluorescence assay (IIF) was used to detect anti-LGI1 antibody. Four cases were positive in both serum and cerebrospinal fluid, while 6 cases only in serum and 4 cases only in cerebrospinal fluid. The follow-up results of 6 to 24 months after intravenous hormone or immunoglobulin therapies showed no one died; the sequelae were memory deficit in 3 cases, faciobrachial dystonic seizures in one case, hyponatremia in 2 cases, sleep disorders in one case. Conclusions Anti-LGI1 antibody-related encephalitis is often characterized by cognitive impairment, seizures, sleep disorders and hyponatremia. Immunotherapy is effective, which has good prognosis comparatively.
