概括
胃腹血管外解症 (GAVE) 影响7%的全身性硬化症 (SSc) 患者,特别是那些患有扩散性,快速进展的疾病的人. 在SSc患者中早期检测具有抗RNA聚合酶III抗体的GAVE对于预防并发症至关重要.
科学领域:
- 胃肠病学 胃肠病学
- 类风湿病学 类风湿病学
- 内部医学 内部医学
背景情况:
- 胃腹腔血管切解症 (GAVE) 是系统性硬化症 (SSc) 中胃肠道出血的公认原因之一.
- 在SSc患者中GAVE的预测因子和结果仍未完全定义.
- 了解GAVE在SSc中的特征对于及时诊断和管理至关重要.
研究的目的:
- 为了确定日本系统性硬化症患者队列中的GAVE的频率.
- 为了比较SSc患者与没有GAVE之间的临床特征.
- 在SSc.中确定与GAVE相关的预测因素和结果.
主要方法:
- 对272名SSc患者的回顾性分析,这些患者在2006年至2015年期间接受了上部胃肠内镜检查.
- 收集临床数据,包括SSc亚型,皮肤硬化程度和自身抗体概况.
- 基于内镜确认的GAVE的存在或不存在的患者特征的比较.
主要成果:
- 在7.0% (19/272) 的SSc患者中发现了GAVE.
- 患有GAVE的SSc患者更有可能患有扩散皮肤SSc,疾病持续时间更短,抗RNA聚合酶III抗体的患病率更高 (42%vs9.5%).
- 在GAVE患者中,结核性性危机的发病率较高 (16%与<1%相比),GAVE病变在1至8年内大约一半的病例中消失,通常是通过免疫抑制治疗.
结论:

The JAK-STAT Signaling Pathway
12.1K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies
492
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...

Autoimmune Disorders
1.5K
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Genome-wide Association Studies-GWAS
15.3K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
