Case Definitions for Neuropsychiatric Syndromes in Systemic Lupus Erythematosus系统性红斑狼疮神经精神综合征的定义Acute Inflammatory Demyelinating Polyradiculoneuropathy (Guillain-Barré Syndrome)急性炎症性多神经根脱髓鞘性神经病(Guillain-Barre综合征)Acute, inflammatory, and demyelinating syndrome of spinal roots, peripheral, and occasionally cranial nerves.脊神经根和外周神经的急性炎症性脱髓鞘综合征,有时也累及颅神经。
Diagnostic criteria:诊断标准:A.Clinical features临床特点1.Progressive polyradiculoneuropathy, usually ascendingand predominantly motor, which peaks usually within 21days or less进行性多神经根神经病,主要累及运动神经,通常由下而上发展,在21天或更少的时间内达到疾病高峰2.Reflex loss反射减退3.Symmetric, may involve the trunk and may causerespiratory failure对称性发病,可累及躯干并引起呼吸衰竭B.CSF脑脊液Increased CSF protein without pleocytosis脑脊液蛋白含量增高而不伴有细胞数增多C.Supportive evidence by nerve conduction study (NCS)including F-wave ascertainment whereby there is ≥ 1abnormality in ≥ 3 nerves (1)包括F波测量的神经传导检查至少在3根神经上发现有1个以上的异常表现The abnormalities are:这些异常表现包括:∙Conduction block in which the amplitude of compoundmuscle action potential diminishes with more proximal sitesof nerve stimulation传导阻滞,表现为由近端神经刺激所产生的复合肌肉动作电位幅度减小∙ F waves may be absent or prolongedF波缺失延长∙Slowing of conduction velocity传导速度减慢∙Prolongation of distal latencies远端潜伏期延长NB: Nerve conduction abnormalities may be subtle in early stages and may need to be repeated.注意:神经传导异常在疾病早期可以很轻微,可能需要重复检查。
