概括

在类风湿性关节炎 (RA) 患者中抗pentraxin-3 (anti-PTX3) 抗体升高表明疾病活动正在进行中. 这些抗体可能表明真正的活跃疾病,特别是在血清阴性RA中,可能突出显示治疗不足.

科学领域:

免疫学免疫学免疫学
类风湿病学类风湿病学
生物标志物发现发现

背景情况:

类风湿性关节炎 (RA) 是一种慢性自身免疫性疾病,其特征是关节炎症.
准确评估疾病活动对于有效的RA管理至关重要.
潘特拉辛-3 (PTX3) 是一种急性阶段蛋白质,与炎症有关.

研究的目的:

在血清阳性和血清阴性RA患者中量化抗PTX3抗体.
调查抗PTX3抗体与疾病活性和患者报告结果 (PROM) 的关联.
探索抗PTX3抗体作为RA中的生物标志物的潜力.

主要方法:

对83名RA患者的横截面研究符合ACR/EULAR 2010标准.
通过内部ELISA测量血清抗PTX3抗体.
与患有牛皮关节炎 (PsA) 和纤维肌痛 (FM) 的历史对照进行比较.
对与临床疾病活性指数 (CDAI,PtGA) 和PROMs (HAQ) 的相关性分析.

主要成果:

血清阴性RA患者表现出比血清阳性RA患者更高的抗PTX3水平.
反PTX3抗体与CDAI,PtGA和HAQ正相关,与VAS-GH负相关.
与控制的RA相比,在接近控制的RA患者中观察到较高的抗PTX3水平.
与TNFi或JAKi相比,使用托西利祖马布或阿巴塔塞普的治疗与较低的抗PTX3水平有关.

结论:

在RA中抗PTX3抗体升高可能意味着尽管炎症得到控制,但疾病的残留活性仍然存在.
反PTX3抗体可以作为RA中真正活跃疾病的生物标志物.
这种生物标志物可能特别适用于识别潜在的治疗不足的血清阴性RA患者.

Rheumatic Heart Disease III: Medical Management

Rheumatic heart disease (RHD) management can be divided into two main strategies: prevention and long-term management.Primary PreventionPrimary prevention focuses on timely diagnosis and management of group A streptococcal pharyngitis to prevent acute rheumatic fever. The most widely used antibiotic for treating this condition is intramuscular benzathine penicillin G.Acute Rheumatic Fever TreatmentThe primary treatment goal for a patient diagnosed with acute rheumatic fever is to suppress the...

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...
