概括

三硫酸二糖胺 (TS-HDS) IgM测试显示神经病变表型的特异性有限. 与血清阴性个体相比,在TS-HDS IgM阳性患者中,免疫治疗的临床改善并不比血清阴性个体更频繁.

科学领域:

神经学神经学
免疫学免疫学免疫学
临床诊断临床诊断临床诊断

背景情况:

三硫酸乙二糖化物 (TS-HDS) IgM抗体与某些神经病变有关.
评估TS-HDS IgM测试的临床实用性对于准确的诊断和治疗至关重要.

研究的目的:

评估TS-HDS IgM测试在第三级护理环境中的实际临床实用性.
确定神经病变患者中TS-HDS IgM抗体的特异性和诊断价值.

主要方法:

在梅奥诊所 (Mayo Clinic) 进行了积极的TS-HDS抗体患者病历的回顾性审查 (2009-2022年).
分析患者的人口统计,神经病变表型,诊断测试结果和免疫治疗反应.

主要成果:

在77名阳性TS-HDS IgM患者中,34%缺乏神经病变的客观证据,12%有其他已知的原因.
常见的表型包括长度依赖的外围神经病变 (48%) 和小纤维神经病变 (26%).
只有31%的TS-HDS IgM阳性患者通过免疫治疗得到改善,与血清阴性患者相比没有显著差异.

结论:

TS-HDS IgM 测试表明表型和疾病特异性有限.
TS-HDS IgM抗体的存在不能可靠地预测神经病变患者对免疫治疗的反应.

关键词:

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
