概括
高分辨率CT (HRCT) 在类风湿性关节炎 (RA) -ILD和全身性硬化症 (SSc) -ILD中显示出适度一致,但在异常性炎症性肌肉病变 (IIM) -ILD中没有. 反MDA5+ IIM-ILD正在快速发展,突出了HRCT的局限性.
科学领域:
- 肺部医学 肺部医学
- 类风湿病学 类风湿病学
- 放射学 放射学是一门学科.
背景情况:
- 高分辨率CT (HRCT) 对于诊断系统性自身免疫性风湿性疾病 (SARDs) 中的间歇性肺病 (ILD) 是至关重要的.
- 通过肺活检进行组织学确认在SARD-ILD中很少进行.
- 评估HRCT发现与探索病理学之间的一致性对于理解诊断准确性至关重要.
研究的目的:
- 评估HRCT成像和SARD-ILD患者肺移植患者的探索病理之间的一致性.
- 调查不同SARD亚型的HRCT-组织学协议的潜在差异,包括异常性炎症性肌肉病 (IIM),全身性硬化症 (SSc) 和类风湿性关节炎 (RA).
主要方法:
- 在2012年至2024年期间在加拿大两个中心接受肺移植的82名SARD-ILD患者的回顾性分析.
- 使用加权卡帕 (κ) 统计数据量化HRCT-组织学一致性.
- 用流图来可视化结果.
主要成果:
- 风湿性关节炎-ILD (RA-ILD) 显示了中度的HRCT-组织学一致性 (κ=0.46),而全身性硬化症-ILD (SSc-ILD) 显示了公平的,非显著的一致性 (κ=0.31).
- 无病性炎症性肌肉病变-ILD (IIM-ILD) 没有表现出有意义的HRCT-组织学相关性 (κ=0.07) 和显著的组织学异质性.
- 抗MDA5+IIM患者普遍经历了快速进展的ILD,通常与扩散性膜损伤或末期纤维化有关,无论最初的HRCT发现如何.
结论:
- 在SSc-ILD和RA-ILD中,HRCT-组织学相关性相当或适度,但在IIM-ILD中由于显著的组织学异质性而受到限制.
- 人类基因组治疗可能无法准确预测IIM-ILD的特定病理或攻击性,特别是在抗MDA5阳性病例中.
- 该研究强调了仅依靠HRCT来诊断和预测IIM-ILD的过程的局限性.

Rheumatic Heart Disease I: Introduction
558
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...

Rheumatic Heart Disease IV: Nursing Management
346
AssessmentA comprehensive assessment is essential in managing a patient with rheumatic heart disease (RHD). Begin with obtaining a detailed medical history, including recent streptococcal infections, a history of rheumatic fever, or previously diagnosed rheumatic heart disease. Assess the patient for symptoms such as fever, chest pain, widespread joint pain (arthralgia), tachycardia, pericardial friction rub, muffled heart sounds, heart murmurs, peripheral edema, subcutaneous nodules, and...

Rheumatic Heart Disease III: Medical Management
380
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
667
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...

Inflammatory Bowel Disease II: Crohn's Disease

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...

Immunodeficiency Diseases
2.5K
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
