This is a clinical research study to assess whether after exhaling a single cigarette smoke through the nose there are changes in the inflammatory cells and proteins of nasal secretions. A single blood sample from each subject will be stimulated with cigarette smoke in the laboratory to see the effects on inflammatory blood cells. Comparison of findings between smokers with COPD and "Healthy" smokers will be carried out. We hypothesize that some subjects have amplified inflammatory response to a single cigarette, and these will be those subjects who develop chronic obstructive pulmonary disease (COPD) after decades of smoking. We hope to develop an acute challenge model that relates to the causation of COPD. When studying the effects of new drugs, these may be detected in small numbers of patients in a challenge situation, when we would need to study many more unchallenged patients to demonstrate drug effects. In clinical research on asthma and allergy, the nasal allergen challenge has been a very successful model, and we hope to validate a comparable model for COPD.
The primary aim of this study is to investigate the effects of inhaled lipopolysaccharide endotoxin (LPS) on bronchial and alveolar exhaled nitric oxide (NO) and NO metabolites and other inflammatory markers and mediators in exhaled breath condensate, induced sputum, nasal lavage and mouthwash fluid in healthy non-smokers and current smokers, including patients with chronic obstructive pulmonary disease (COPD).
T.to investigate a possible mechanism of the glucocorticosteroid receptors (GR) defect in patients with severe COPD by studying the effect of dexamethasone (Dex) on GR- binding, interleukin production (IL-6/IL-8) and MKP-1 expression in peripheral blood mononuclear cells blood (PBMC)
The objective of this trial is to determine whether tiotropium inhalation capsules (Spiriva, Bromuro de Tiotropio), compared to placebo, enhances the improvement in exercise tolerance seen in patients with chronic obstructive pulmonary disease (COPD) who participate in pulmonary rehabilitation.
This study was conducted to evaluate the safety and pharmacokinetics of an echocardiographic contrast agent, AI-700, in patients with moderate to severe chronic obstructive pulmonary disease (COPD) and/or congestive heart failure (CHF).
The objective of this trial is to compare the total and regional deposition of aerosol in the lungs and oropharynx of patients with COPD at 3 different inspiratory flow rates following inhalation of Berodual delivered via the Respimat inhaler and Berodual? delivered via an HFA-metered dose inhaler.
The primary objective of this study is to demonstrate the superiority of tiotropium compared to placebo in the treatment of patients with COPD and a concomitant diagnosis of asthma
Approximately 20% of patients with chronic obstructive pulmonary disease (COPD) have major depression, a condition that contributes to suffering but also to poor treatment adherence leading to increased disability and morbidity. This study investigates the effectiveness of a care management intervention aimed at facilitating adherence to a treatment algorithm based on the Agency for Health Care Policy and Research (AHCPR) guidelines. The investigators hypothesize that this intervention, in comparison to usual care, will increase the prescription of adequate antidepressant treatment by physicians, enhance treatment adherence by patients, and reduce depressive symptoms, suicide ideation, and disability at a 28-week follow-up period.
Pulmonary inflammation plays an important role in the development of chronic lung disease (CLD) in preterm infants. This inflammation occurs very early in postnatal life. Any therapy that could be beneficial in preventing CLD should be started very early. The investigators' previous double-blind study has shown that early (< 12 hours) postnatal use of intravenous dexamethasone for 4 weeks significantly suppressed pulmonary inflammation and significantly reduced the incidence of CLD. However, the use of dexamethasone was associated with increased incidence of infection and sepsis. Their follow-up study also suggested an increase in the incidence of psychomotor anomalies. As compared to intravenous administration, endotracheal instillation will provide more local anti-inflammatory effects and less systemic side effects. Infants will be eligible for the study if their birth weight (BW) is < 1500 gm and if they had severe respiratory distress syndrome (RDS) requiring mechanical ventilation shortly after birth. After informed consent is obtained, the infant will be randomly assigned depending on the condition of the infant. The primary outcome is the change in cytokines (interleukin-6, 8, 10 and TNF-α) levels in BAL fluid. Chronic lung disease (CLD) was judged at 36 postmenstrual weeks. Infants in the study group (S/B group) received surfactant (Survanta®, Abbott Laboratories, North Chicago, IL; 100 mg or 4 mL/kg/dose) and Budesonide (Pulmicort®, AstraZeneca Pty Ltd., Australia; 0.5 mg or 1mL/kg/dose), while those in the control group (S group) received surfactant (Survanta® Abbott, 100 mg/kg/dose) and saline (1mL/kg).
