概括
系统性硬化症 (SSc) 患者持续升高的C-反应蛋白 (CRP) 表明慢性炎症,显著增加动脉样心血管疾病风险,并表明明显的炎症性SSc亚型. 这一发现凸显了对SSc患者群体进行进一步研究的需要.
科学领域:
- 心血管医学 心血管医学
- 类风湿病学 类风湿病学
- 炎症研究 炎症研究
背景情况:
- 系统性硬化症 (SSc) 的特点是血管病变,增加心血管疾病 (CVD) 的风险.
- 升高的C-反应蛋白 (CRP) 表示20-25%的SSc患者慢性低度炎症.
- 在SSc中,CRP阳性与心血管疾病/动脉样硬化之间的联系尚未完全理解.
研究的目的:
- 在SSc患者中确定与CRP阳性相关的参数.
- 调查CRP阳性是否与较高的心血管疾病风险和动脉样硬化负担相关.
- 用随机森林建模来确定哪些参数最能区分一个"炎症性SSc亚型".
主要方法:
- 根据CRP水平,65名SSc患者被分为CRP阳性 (CRP+) 和CRP阴性 (CRP-) 组.
- 评估包括病史,体检,血液检查,心血管超声波 (斑块,CIMT) 和10年ASCVD风险估计.
- 统计分析涉及相关性,后勤回归和随机森林分类.
主要成果:
- 与CRP-SSc患者相比,CRP+SSc患者的脂质样本 (HDL,LDL,甘油三) 显著变化,10年ASCVD风险更高.
- 在CRP+SSc患者中,CRP水平与心动脉内膜介质厚度 (CIMT) 有积极的相关性.
- 脂质成分或SSc持续时间/ASCVD类别有效区分CRP阳性SSc患者.
结论:
- 在SSc患者中持续的CRP阳性显著增加了动脉样心血管疾病的风险.
- 这表明一种独特的"炎症性"SSc亚型,其特征是CRP升高和脂质配置中断.
- 需要进一步的大规模研究和临床试验来验证这些发现.

Rheumatic Heart Disease I: Introduction

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

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...

Chronic Bowel Disorders: Introduction

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
