METHODS
This retrospective and descriptive study evaluated the clinical characteristics and outcomes of patients with CA-GAD-ab.
RESULT
Three patients with cerebellar ataxia, high GAD-ab titers and autoimmune endocrine disease were identified. Patients 1 and 2 had classic stiff person syndrome and insidious-onset cerebellar ataxia, while Patient 3 had pure cerebellar ataxia with subacute onset. Patients received intravenous immunoglobulin therapy with no response in Patients 1 and 3 and partial recovery in Patient 2.
CONCLUSION
CA-GAD-ab is rare and its clinical presentation may hamper diagnosis. Clinicians should be able to recognize this potentially treatable autoimmune cerebellar ataxia.
方法
本回顾性描述性研究评估了伴有抗谷氨酸脱羧酶自身抗体（CA-GAD-ab）患者的临床特征及预后。
结果
确诊3例患有小脑性共济失调、高GAD-ab滴度及自身免疫性内分泌疾病的患者。患者1和患者2患有典型的僵人综合征及隐匿起病的小脑性共济失调，而患者3患有亚急性起病的单纯小脑性共济失调。患者接受静脉注射免疫球蛋白治疗，患者1和患者3无反应，患者2部分恢复。
结论
CA-GAD-ab罕见，其临床表现可能妨碍诊断。临床医生应能够识别这种潜在可治疗的自身免疫性小脑性共济失调。
