まとめ
軸性脊椎関節炎 (axSpA) の患者は,一般人よりも多くの併発性疾患があり,その中にはウエビチスやIBDのような特定の疾患が含まれています. 非放射性および放射性 axSpAの併発症の違いは見つかりませんでした.
科学分野:
- リウマトロジ
- 流行病学
- 臨床医学
背景:
- 軸性脊椎関節炎 (axSpA) は慢性的な炎症性疾患である.
- axSpAにおける併発症の負担を理解することは,患者の管理に極めて重要です.
- 以前の研究では,axSpAにおける併発症を一般集団と,または疾患サブタイプとの間で全面的に比較していなかった.
研究 の 目的:
- 軸性脊椎関節炎 (axSpA) 患者における様々な併発症の流行を一般患者と比較する.
- 非放射性 axSpA (nr-axSpA) と放射性 axSpA (r-axSpA) の併発症率の違いを調査する.
主な方法:
- 246人のaxSpA患者 (SPARTAKUS) のコホートは,患者1人あたり5人の対照群とマッチングされた.
- 併発症 (59の疾患) は,10年間のICD-10診断を用いて特定された.
- グループ間の共病率を比較するために,ロジスティック回帰分析を使用した.
主要な成果:
- AxSpA患者では,対照群と比較して,前頭炎,IBD,牛皮病,心筋痛症/慢性疼痛,腎石炎の有意に高い罹患率を示した.
- 胃炎,高血圧,白内障,緑内障,骨粗鬆症の増加が axSpA患者で観察され,NSAIDおよびグルココルチコイド使用と関連している可能性がある.
- nr- axSpA患者とr- axSpA患者との間で,併発症の全体的な差異は認められなかった.
結論:
- 軸性脊椎関節炎は,既知の筋骨外症状を超えて,かなりの併発症負担と関連しています.
- 長期にわたる炎症および治療の副作用 (NSAID,グルココルチコイド) は,併発性プロファイルの強化に寄与している可能性が高い.
- 疾患分類 (nr- axSpA vs. r- axSpA) は共病スペクトルに影響を与えないようです.

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...

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Factors Affecting Illness
4.4K
When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness,...

Autoimmune Disorders

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.
