Modification Of Disease Outcome In COPD
Modification of Disease Outcome in COPD. Shortterm Versus Longterm Treatment With Inhaled Corticosteroids, Either or Not Combined With a Long-Acting Beta2-Agonist.
調査の概要
詳細な説明
Aim The primary aim of this study was to investigate whether short-term treatment with inhaled corticosteroids in COPD results in greater improvements in airway pathology, thereby leading to larger clinical benefits, than continuous long-term treatment. To that end, the outcome variables included features of airways inflammation and remodelling as well as clinical symptoms, exacerbations, quality of life, decline in FEV1, bronchial responsiveness, and pharmaco-economics. The secondary aim of the study was to examine the histopathological and clinical benefits of the combined treatment with an inhaled steroid and a long-acting ß2-agonist in COPD.
Methods Patients. Patients with COPD (45-75 yr, >10 pckyr) not using inhaled steroids for the past 3 months were recruited.
Design. In a prospective, longitudinal, double blind, 4-arm study, the patients were followed during 2.5 years (Figure 1). They were treated with high dose inhaled corticosteroids (500 g fluticasone bid), combined inhaled steroids+long-acting ß2-agonist (500 µg fluticasone+50 µg salmeterol) or placebo for 6 months. Half of the patients in the steroid group continued their treatment with steroids for another 2 years, whereas the other half received placebo. The combination therapy and placebo groups remained unaltered treatment up to 2.5 years.
Measurements. Symptoms, exacerbations, QOL questionnaires and spirometry were monitored every 3 months. Peripheral blood eosinophils, IgE, exhaled NO, bodyplethysmography, CO-diffusion capacity, PC20 methacholine, sputum induction and bronchoscopy were performed at 0, 6, and 30 months. In BAL and induced sputum we are measuring cell differentials and their state of activation. Immunohistochemistry is being performed in bronchial biopsy specimens, staining for markers on infiltrative and resident cells, and morphometric analysis will allow airway remodelling to be quantified, by using a computerized image analysis system. The effects of treatment will be analyzed by relating the observed changes in clinical and pathophysiological outcome, to those in cellular and histological outcome by using linear mixed statistical models.
