まとめ
肺の超音波検査 (LUS) は,健康な被験者と比較して,脊椎関節炎 (SpA) の患者において,膜線不規則性 (PLI) の増加を示しています. 喫煙は,この SpA 集団におけるより高い PLI に関する唯一の臨床的要因です.
科学分野:
- リウマトロジ
- 肺科
- 医療用イメージング
背景:
- インタースティシャル肺疾患 (ILD) は,関節リウマチ (RA) の一般的な合併症であり,死亡の主な原因です.
- 脊椎関節炎 (SpA) は,疾患の負担と治療においてRAと類似性がありますが,ILDの評価は困難です.
- 肺の超音波検査 (LUS) は,自己免疫疾患におけるILDを評価するための有望な,低放射線の代替手段です.
研究 の 目的:
- 健康な被験者 (HS) と比較して,LUSを使用するSPA患者におけるILDの罹患率を決定する.
- LUS経由で,SPA患者におけるILD指標と臨床的特徴の相関を調査する.
主な方法:
- 連続したSPAの外科医とHSはLUSを受け,71の肋間間間隙間 (PLI) に関する膜線不規則性を評価した.
- 肺部全体のスコアを計算し,患者は呼吸器と全身健康に関する検証されたアンケートを記入した.
- 病気の特徴と薬剤の使用を含む臨床データは,医療記録から収集されました.
主要な成果:
- SpAの患者は,HSの患者よりPLIの合計スコアが有意に高い (p < 0. 001).
- 前頭部と側頭部より高いPLIを示し,喫煙はSPAとHSの両グループで高いPLIを予測した.
- PLIスコアと患者の報告したアウトカム,疾患の活動,持続時間,またはMTX/生物学的薬の使用は,前胸PLIとSF-36スコアとの関連を除いて,有意な相関関係が見つかりませんでした.
結論:
- LUSは,健康な個人と比較して,SpA患者におけるPLIのより高い罹患率を示しています.
- 喫煙習慣は,研究対象集団におけるPLI増加と有意に関連した唯一の臨床的特徴であった.
- LUSは SpAにおける ILDを評価するための貴重なツールであり,喫煙を重要な関連因子として強調しています.

Chronic Obstructive Pulmonary Disease-I: Introduction
2.9K
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.

COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

COPD: Pathogenesis and Clinical Features

Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
