Effects of inhaled alpha-1-anti-trypsin in bronchiectasis patients with chronic bronchial infection.
Introduction: one of the main features of bronchiectasis is chronic and deregulated neutrophilic bronchial inflammation. Excessive neutrophilic elastase (NE) activity has been widely described as
Alpha-1 Antitrypsin (A1AT) is a major inhibitor of serine proteases and plays an important role in the lung as an inhibitor of neutrophil elastase. A1AT deficiency is associated with decreases in plasma A1AT levels and is associated with an increased risk for developing asthma, emphysema/COPD, and
Alpha-1 Antitrypsin Deficiency (AATD, Alpha-1) is a genetic condition that predisposes to early onset pulmonary emphysema and airways obstruction, often indistinguishable from usual smoker's chronic obstructive pulmonary disease (COPD). Prominent features of AATD COPD include basilar predominant
Objectives
1. To demonstrate the presence of NE in vitro and the entrance into lung adenocarcinoma cells
2. To identify the intracellular mechanisms through which NE mediates its tumor proliferating effects
3. To verify the activation of NE and its related pathway component in clinical lung
BACKGROUND AND RATIONAL FOR STUDY Bronchiectasis is a chronic debilitating respiratory condition. Patients suffer daily cough, excess sputum production and recurrent chest infections because of inflamed and permanently damaged airways. It is a common with a Scottish incidence of 1 in 1,000 to 1 in

1.1 Background
Chronic obstructive pulmonary disease (COPD) is a major health problem across the world and its medical, societal and economic impacts continue to grow. COPD is characterized by chronic obstruction of expiratory flow affecting peripheral airways, associated with chronic bronchitis
Research plan:
Fifty-four subjects will be recruited from the Department of AIRMED outpatient clinics at the Alfred Hospital, Melbourne. Subjects will be considered eligible if they have a diagnosis of COPD or bronchiectasis and are clinically stable.
Subjects who give their consent will undergo the
