概括
治疗 transthyretin amyloid心肌病 (ATTR-CM) 的diflunisal疗法耐受性良好,并显示出稳定心脏变化的趋势. 虽然并没有改善所有标志物,但通过心脏MRI和生物标志物评估,它减缓了疾病的进展.
科学领域:
- 心脏病学 心脏病学
- 心血管成像 - 心血管成像
- 药理学 药理学是指药理学的学科.
背景情况:
- 越来越多的人认识到Transthyretin amyloid心肌病变性 (ATTR-CM).
- 目前正在研究疾病修饰疗法,包括TTR稳定剂,如diflunisal.
- 有限的数据存在于diflunisal对ATTR-CM使用心脏磁共振 (CMR) 的形态变化的影响.
研究的目的:
- 通过CMR和其他临床评估,探索diflunisal对ATTR-CM进展的影响.
- 评估diflunisal在ATTR-CM患者中的安全性和耐受性.
主要方法:
- 一项开放标签的试点研究 (AMILCA-DIFLU) 评估了患者在治疗diflunisal之前和一年后.
- 包括临床,功能,生化和CMR评估.
- 增加了7名现实世界患者来增加样本大小.
主要成果:
- 一年后,Diflunisal没有显著改善心脏生物标志物,6分钟步行测试 (6MWT) 或CMR参数.
- 观察到CMR参数 (LVEF,ECV,T2) 的稳定趋势不显著.
- 完成治疗的患者与没有完成治疗的患者相比,6MWT距离显著减少.
- 迪弗鲁尼萨尔 (Diflunisal) 一般耐受性很好,功能有轻微的,非临床相关的恶化.

Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...

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...

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...
