Background: Inhaled corticosteroids (ICS) markedly reduce bronchial mucosal inflammation in asthma but whether they have an anti-inflammatory effect in airway tissue in chronic obstructive pulmonary disease (COPD) is unknown.
Methods: A study of endobronchial biopsy samples was conducted as part of a double blind, placebo controlled, randomised trial of parallel design. Patients had mild to moderately severe COPD (FEV(1) 25-80% of predicted) and were given 3 months treatment with ICS, fluticasone propionate (FP; 500 micro g twice daily, n=14) or placebo (n=10).

Inhaled corticosteroids (ICS) are effective in the treatment of asthma and markedly reduce the numbers of inflammatory cells in bronchial biopsies. However, the effect of ICS on the inflammatory profile of biopsies in smokers with chronic obstructive pulmonary disease (COPD) is unknown. We have performed a double-blind, placebo-controlled, randomized study to compare fluticasone propionate (FP) 500 microg twice daily via a dry powder inhaler and placebo (P) over a 3-month period in subjects with COPD.

Eosinophilia has been reported during exacerbations of bronchitis, but the mechanisms of tissue recruitment of eosinophils are unclear. We quantified eosinophils and the concurrent expression of cytokines and chemokines probably responsible for the tissue eosinophilia in bronchial biopsies obtained from three groups of nonatopic subjects: (1) healthy nonsmokers (n = 7; FEV1 % predicted = 108 +/- 4 [mean +/- SEM]); (2) nonasthmatic smokers with chronic bronchitis (CB) in a stable phase of their disease (n = 11; FEV1 % predicted: 75 +/- 5); and (3) nonasthmatic subjects with CB who sought medical advice for an exacerbation of their condition (n = 9; FEV(1) % predicted: 61 +/- 8). We applied anti-EG2 antibody and immunostaining to detect and count eosinophils.

Bronchial inflammation is a consistent feature of asthma and its chronicity probably determines disease progression. Clinical evaluation of drugs with potential disease-modifying activity requires measurement of their effects on the inflammatory and remodelling process using a variety of techniques including bronchial biopsy, and analysis of sputum, bronchoalveolar lavage, blood, urine and exhaled air. Markers of the key components of the inflammatory process, such as the number and activation of T-cells.

(1) Chronic bronchitis (mucous hypersecretion) is an inflammatory condition in which CD8+ T-lymphocytes, neutrophils, and CD68+ monocytes/macrophages predominate. The condition is defined clinically by the presence of chronic cough and recurrent increases in bronchial secretions sufficient to cause expectoration.
