概括
间歇性肺病 (ILD) 影响多达38%的全身性硬化症患者,即使没有皮肤参与. 在全身性硬化症 (SSc) 患者中,早期发现ILD至关重要,特别是那些早期或有限的皮肤疾病患者.
科学领域:
- 类风湿病学 类风湿病学
- 肺部病理学 肺部病理学
- 放射学 放射学是一门学科.
背景情况:
- 间歇性肺病 (ILD) 是系统性硬化症 (SSc) 的主要并发症和死亡原因.
- ILD可以在早期阶段 (eSSc) 或在已确定的疾病但没有皮肤参与 (ssSSc) 的患者中表现出来.
研究的目的:
- 为了确定系统性硬化症患者中ILD的流行率,早期或有限的皮肤参与.
- 在这些特定的SSc子集中识别与ILD相关的风险因素.
主要方法:
- 对353名SSc患者 (65名SSSSc,75名VEDOSS) 的高分辨率胸部CT扫描进行了回顾性分析.
- 包括标准分为ssSSc (ACR/EULAR 2013,罗丹皮肤得分0) 和eSSc (VEDOSS标准) 之间的区别.
- 进行了单变量和多变量分析,以确定ILD的风险因素.
主要成果:
- 在ssSSc组中,ILD的患病率为38%,在VEDOSS (eSSc) 组中为20%.
- 抗中心体抗体阳性显示出对ILD的保护作用 (OR 0.17).
- 抗SCL-70抗体的存在是ILD (OR 35.8) 的重要危险因素.
结论:
- 在SSc患者中,ILD很普遍,在早期和有限的皮肤参与子集中发生.
- 建议在这些患者群体中积极寻找ILD,因为其患病率很高.
- 特定的自身抗体 (抗SCL-70) 与增加ILD风险有关,而其他抗体 (抗中心体) 可能具有保护作用.

Chronic Obstructive Pulmonary Disease-I: Introduction
2.7K
Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.

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...

Pulmonary Tuberculosis I
210
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Autoimmune Disorders
348
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.

Asthma-I: Introduction
2.6K
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...
