まとめ
経口用コルチコステロイドは,肺サーコイドーシスにおける胸部X線と肺機能を著しく改善します. しかし,吸入用コルチコステロイドは一貫性のない結果を示し,ステロイドによる長期的な疾患改変はまだ証明されていません.
科学分野:
- 肺内科 肺内科 肺内科
- 臨床薬理学 臨床薬理学とは
- 根拠に基づいた医学は,証拠に基づいた医療です.
背景:
- 肺性サルコイド症の治療には,しばしば症状を管理し,肺損傷を防ぐためにコルチコステロイドが含まれます.
- 自発的な寛解は一般的ですが,疾患の重症度が治療決定と治療反応に影響を及ぼします.
- ランダム化対照試験は,肺性サルコイドーシスにおけるコルチコステロイドの有効性を評価するために不可欠です.
研究 の 目的:
- 経口および吸入用コルチコステロイドが,肺性サルコイドーシスにおける放射線検査結果,症状,肺機能に与える影響を評価する.
- 肺性サルコイド症のコルチコステロイド治療に関連する長期的なアウトカムを評価する.
主な方法:
- 2001年12月までの間,複数のデータベース (MEDLINE,EMBASE,CINAHL,Cochrane) の包括的な文献検索を行った.
- コントロールグループ,肺性サルコイドーシスが確認された成人参加者,および少なくとも8週間のコルチコステロイド治療を含むランダム化比較試験の含有.
- Jadadスコアを用いた品質評価と,主要著者によるデータ検証.
主要な成果:
- 経口用コルチコステロイドは,ステージ2および3の疾患を有する患者において,胸部X線写真 (Peto OR, 2.54) と肺機能 (強制生命能力,拡散能力) の有意な改善を示した.
- 吸入用コルチコステロイドは,胸部X線写真に有意な効果を示せず,小さな限られた研究で肺機能と症状に矛盾した効果を示しました.
- コルチコステロイドの離脱後の疾患変容効果を評価するためのデータはありませんでした.
結論:
- 経口用コルチコステロイドは,放射線検査の結果を効果的に改善し,肺サルコイド症の肺機能にわずかな改善をもたらします.
- 吸入用コルチコステロイドの有効性は,研究規模が小さく,結果が一貫していないため,依然として不確実です.
- 現在の証拠は,サルコイドーシスの長期的な進行を変化させる手段として,コルチコステロイド療法を支持していません.

Asthma: Pathogenesis and Management
1.5K
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids
2.1K
Inhaled corticosteroids (ICS) are anti-inflammatory drugs used primarily in treating persistent asthma and providing long-term maintenance. They target the bronchial mucosa, the lining of the airways, to control inflammation, a critical factor in asthma progression and exacerbation.
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...

COPD: Management Using Bronchodilators and Corticosteroids
1.2K
Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...

Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids
692
Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2...

Chronic Obstructive Pulmonary Disease-V: Management
3.3K
Managing Chronic Obstructive Pulmonary Disease (COPD) involves a multifaceted approach to reduce symptoms, prevent exacerbations, improve overall health status, and slow disease progression. Key strategies include lifestyle modifications, pharmacotherapy, supportive therapies, and, in some cases, surgery. Here is an overview of the primary COPD management strategies:

Cushing Syndrome I: Introduction
36
Cushing syndrome refers to the collection of clinical manifestations that arise when tissues are exposed to excessive amounts of cortisol or cortisol-like medications over an extended period. Cortisol, a glucocorticoid produced by the adrenal cortex, regulates metabolism, immune responses, and the body’s adaptation to stress. When its concentration remains chronically elevated, these physiological pathways become dysregulated, resulting in the characteristic features of the...
