まとめ
デュシェンヌ筋縮症におけるコルチコステロイドの使用は,黒人男性および家族歴のある人に対して持続的な遅延を示しています. 診断のタイミングは これらの遅延に影響し 健康上の不平等を強調しています
科学分野:
- 神経科学
- 小児科
- 遺伝学
背景:
- コルチコステロイドは,デュシェンヌ筋縮症 (DMD) の基礎治療である.
- 以前の研究では,人種や家族歴に基づいてコルチコステロイドの投与開始の格差が示されました.
- これらのパターンを理解することは 公平なケアに不可欠です
研究 の 目的:
- DMDにおけるコルチコステロイド使用パターンと患者の人口統計の関連性を更新し,再検討する.
- コルチコステロイド投与開始の遅延における診断タイミングの役割を調査する.
- 医療へのアクセスに影響を及ぼす 潜在的な不平等を特定する.
主な方法:
- 6か所のDMD患者373人のデータを分析した (2000年~2015年).
- カプラン・マイヤー曲線推定とコックス比例リスクモデルを使用した.
- コルチコステロイドの提供/開始と人種や家族歴などの要因との関連を調べた.
主要な成果:
- 男性の75. 6%にコルチコステロイドが提供され,68. 9%が投与を開始した.
- 以前に観察されたコルチコステロイド使用の遅延は,非ヒスパニック系黒人男性およびDMDの家族歴を有する男性において持続した.
- 非ヒスパニック系黒人男性における遅い診断と,家族歴のある男性における早期診断は,いくつかの遅延を説明する可能性があります.
結論:
- 診断のタイミングは,ダッチェンヌ筋縮症のコルチコステロイド開始の格差を部分的に説明します.
- 非ヒスパニック系黒人男性における診断に影響する健康上の不平等についてさらなる研究が必要である.
- 早期のコルチコステロイド使用の安全性の調査は,DMDの治療を最適化するために重要です.

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
201
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...

Disorders of the Skeletal Muscle
1.1K
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids

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...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
264
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...

Satellite Stem Cells and Muscular Dystrophy
2.0K
Satellite stem cells or myosatellite cells are quiescent stem cells that Alexander Mauro first identified in 1961. These cells are located between the sarcolemma, the plasma membrane of muscle fibers, and the basal lamina, the connective tissue sheath covering it. These mononucleated cells are activated in response to muscle injury, can transform into myoblasts, and may form or repair muscle fibers. Myosatellite cells can provide additional myonuclei for muscle regeneration or return to a...
