概括

血中氨酸在CIDP和GBS等疾病中显示为外周神经脱髓化的生物标志物. 升高的水平表明疾病活跃,并预测恶化,有助于诊断和治疗监测.

科学领域:

神经科学是一个神经科学.
生物化学生物化学
临床医学临床医学

背景情况:

像CIDP和GBS这样的外围神经病变缺乏客观的液体生物标志物来评估疾病.
作为一个潜在的生物标志物,研究人员研究了Periaxin,这是一种独特的蛋白质,用于髓化 Schwann 细胞.

研究的目的:

开发和验证血素作为外周脱髓性神经病变的生物标志物.
评估素在区分外围和中枢神经系统疾病以及跟踪疾病活动方面的能力.

主要方法:

一种基于Simoa的免疫试验被开发来测量血中氨酸水平.
血中氨酸在患有CIDP,GBS,CMT,MS的患者和健康对照中进行测量.
在体外研究中评估了免疫媒介脱髓化后的素释放.

主要成果:

与对照组相比,在CIDP,GBS和CMT中,血中氨酸显著升高 (P < 0.01).
氨酸水平与活性CIDP疾病相关,并在IVIg治疗后降低,预测临床恶化 (AUC 0.86).
在GBS中,素比率区分了AIDP和AMAN (AUC0.94) 并在症状出现后2-3周达到峰值.

结论:

血中氨酸作为外围神经脱髓化的可靠生物标志物.
当与其他生物标志物相结合时,Periaxin有可能提高对外围神经病变的临床管理和研究.

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
