背景:
- エオシノフィルの慢性阻害性肺疾患 (COPD) は,頻繁に悪化し,経口コルチコステロイド (OCS) の使用が増加する.
- Mepolizumabは,抗インターリューキン-5モノクローナル抗体であり,エオシノフィル性呼吸道疾患において有効性を示しています.
研究 の 目的:
- エオシノフィル性COPD患者におけるエキサバーブおよびOCS依存症の軽減におけるメポリズマブの実世界の有効性を評価する.
- メポリズマブが悪化率と入院率に及ぼす長期的な影響を評価する.
主な方法:
- メポリズマブ (100 mg SC 4週間に1回) で治療された13人のCOPD患者を含む,単一センターコホート研究.
- 含有基準:OCSで治療された悪化または維持OCS使用の≥2例,および血液のエオシノフィール>300細胞/μL.
- 応答は,年間OCSを必要とする悪化の≥50%の減少と定義され,2年フォローアップ.
主要な成果:
- 1年目には69%の患者 (9/13) が対応し,年間平均悪化 (4.0~1.0,p=0.007) と入院 (2.0~0.0,p=0.007) が有意に減少した.
- 2年目には持続的な効果が認められ,悪化はさらに減少した (出所値より60%と90%減少).

COPD: Pathogenesis and Clinical Features
1.9K
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...

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...

What is an Experiment?
19.1K
An experiment is a planned activity carried out under controlled conditions. The purpose of an experiment is to investigate the relationship between two variables. When one variable causes change in another, we call the first variable the explanatory or independent variable. The affected variable is called the response or dependent variable. In a randomized experiment, the researcher manipulates values of the explanatory variable and measures the resulting changes in the response variable. The...

Thomson's e/m Experiment
7.0K
In a beam of charged particles created by a heated cathode, the particles move at different speeds. However, many applications need a beam with uniform particle speeds. An arrangement known as a velocity selector uses electric and magnetic fields to pick particles with a particular speed from the beam.
A particle with charge q, speed v, and mass m enters an area from the top, where the magnetic and electric fields are perpendicular both to the particle's motion and to one another. The magnetic...

Controls in Experiments
18.5K
When conducting an experiment, it is crucial to have control to reduce bias and accurately measure the dependent variables. It also marks the results more reliable. Controls are elements in an experiment that have the same characteristics as the treatment groups but are not affected by the independent variable. By sorting these data into control and experimental conditions, the relationship between the dependent and independent variables can be drawn. A randomized experiment always includes a...
