概括

血管超声波 (VUS) 评分,特别是OMERACT GCA US评分 (OGUS),有效预测巨细胞动脉炎 (GCA) 的不良事件. 这些VUS量化得分显示出作为GCA管理和临床试验的生物标志物具有前景.

科学领域:

类风湿病学类风湿病学
医疗成像医学成像
临床诊断临床诊断临床诊断

背景情况:

血管超声波 (VUS) 已建立用于诊断巨细胞关节炎 (GCA).
在监测GCA疾病进展和预测患者结果时,VUS的实用性需要进一步定义.

研究的目的:

评估超声波血管炎量化在GCA诊断和管理中的作用.
评估VUS参数的纵向趋势和正常化.
确定预测VUS结果和不良事件的患者因素.

主要方法:

对GCA患者进行前性队列研究.
在12个月的时间里,内心介质厚度 (IMT),光环计数 (HC),光环分数 (HS) 和OMERACT GCA US分数 (OGUS) 的比较.
相关性和AUC分析以确定VUS结果和不良事件的预测因素.

主要成果:

在12个月内观察到平均HC,HS,IMT和OGUS的显著下降.
在很大一部分患者中,HC,HS和OGUS在6个月内实现正常化.
与临床和实验室参数相比,VUS得分,特别是OGUS,对不良事件具有更高的预测价值.

结论:

VUS量化得分,特别是OGUS,是未来队列中GCA的验证生物标志物.
这些超声波测量在预测不良事件方面优于临床变量.
VUS量化得分有可能成为GCA临床试验中的关键结果变量.

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...
