Pulmonary Disease, Chronic Obstructive | Drug: fluticasone and salmeterol | Phase 1 |
Our objective is to examine the mechanism of the additive/synergistic properties of b2-adrenoceptor stimulation and corticosteroid receptor activation in:
- Preventing neutrophil adhesion to specific endothelial ligands, e.g. ICAM-1 and
- Undergoing activation as a consequence of this adhesion.
We hypothesize that combination therapy with salmeterol + fluticasone (FP) will:
- Augment the inhibition of adhesion of neutrophils obtained from the peripheral blood of study subjects in vitro, by blocking gIV-PLA2 translocation to the nuclear membrane as for eosinophils;
- Augment the inhibition of transendothelial migration of neutrophils into airways of subjects with chronic obstructive pulmonary disease;
- Augment the numbers and concentrations of pro-inflammatory products in the bronchoalveolar lavage fluid; and
- Decrease the number of neutrophils in the bronchial tissue of endobronchial biopsies of treated patients.
