Filter by:The primary objective is to evaluate the efficacy of AZD9668 compared with placebo in symptomatic COPD patients by assessing the effects on lung function and symptoms of COPD
Trial will include 40 subjects and consists of 3 visits: Screening, Treatment and Follow up. A euglycemic clamp procedure and Technosphere®/Insulin (T/I) administration will occur at Visit 2 for both COPD and non COPD subjects.
The purpose of this study is: - to evaluate the optimal time-point for percutaneous dilation tracheostomy in COPD patients in terms of duration on mechanical ventilation, length of stay on ICU and mortality; - to evaluate the rate of infections and infectious complications of tracheostomized COPD patients; - to evaluate the spectrum of pathogens in tracheostomized and intubated COPD patients; - to evaluate the amount of sedatives used in mechanically ventilated COPD patients; - to assess the quality of life in COPD patients tracheostomized after 3 or after 10 days.
A randomised controlled trial will be performed to evaluate the effects of lung volume reduction surgery (LVRS) in patients with COPD on systemic inflammation, oxidative stress, endothelial function, arterial stiffness and blood pressure. We hypothesize that LVRS will lead to a reduction of systemic inflammation, oxidative stress, arterial stiffness and blood pressure and to improved endothelial function. For this purpose 30 patients with severe/very severe COPD (GOLD III-IV) and pulmonary emphysema who are to undergo LVRS will be randomised to one of two groups: group 1 receiving immediate LVRS and group 2 receiving LVRS after a delay of 3 months. Measures of systemic inflammation, oxidative stress, endothelial function, arterial stiffness and blood pressure will be measured at baseline and 3 months after surgery and no surgery, respectively (group 2 receiving surgery only after a delay of 3 months will serve as control group) to investigate the effects of LVRS on the described outcomes.
The investigators hypothesized that the application of volume-controlled HFPPV to the non-dependent lung during one-lung ventilation (OLV) for thoracotomy in patients with good pulmonary functions and mild-to-moderate pulmonary dysfunction may provide preservation of the right ventricular (RV) function, adequate oxygenation and optimum surgical conditions. The investigators evaluated the effects of IL-HFPPV on RV ejection fraction (REF), RV end-diastolic volume (RVEDVI), RV stroke work (RVSWI), pulmonary vascular resistance (PVRI), and stroke volume (SVI) indices, oxygen delivery (DO2) and uptake (VO2), shunt fraction (Qs: Qt), and surgical field conditions during OLV for thoracotomy in patients with good and mild-to-moderate impaired pulmonary functions.
The primary objective of this study is to evaluate long-term safety and patient acceptability of COMBIVENT RESPIMAT Inhalation Spray as compared to the COMBIVENT Inhalation Aerosol Chlorofluorocarbon-Metered Dose Inhaler (CFC-MDI) and the free combination of ATROVENT Hydrofluoroalkane (HFA) and albuterol Hydrofluoroalkane (HFA) inhalation aerosols.
The Purpose of this study is to assess the efficacy and safety of three strengths of the FF/GW642444 Inhalation Powder in subject with Chronic Obstructive Pulmonary Disease (COPD)
The purpose of this study is to investigate the safety, tolerability, pharmacokinetics and pharmacodynamics of inhaled AZD9164 following administration of multiple ascending doses in healthy male and female subjects and COPD patients.
COPD patients often have a wide range of physical (e.g., dyspnea, fatigue, pain) and psychological (e.g., depression, anxiety) symptoms and various other debilitating conditions that cause considerable suffering for the individual. Unfortunately, many of the symptoms and health problems in patients with COPD are unrecognized and untreated. Due to the irreversible nature of COPD, the aim is not to cure the disease, but to reduce symptoms and improve quality of life. Therefore, the purpose of this project is to investigate the existence and nature of symptom clusters over time in patients with COPD and their effects on patient outcomes. Since this study aims to identify possible new subgroups of patients with COPD defined by the clustering of certain symptoms, the study also aims to investigate the relationship between the clinical presentation and certain immunologic and genetic factors.
A double blind randomised placebo controlled parallel trial of the effect of fosinopril, an angiotensin converting enzyme inhibitor, on the quadriceps muscle in 80 COPD patients who have quadriceps weakness. Patients will have a baseline assessment including measures of quadriceps strength and endurance and a quadriceps biopsy. Patients with weakness will be randomised to ACE inhibitor or placebo and re-assessed after three months of treatment. The investigators aim to show that ACE-inhibition will alter the IGF-1/AKT/FoXO/atrogene pathways involved in muscle wasting in COPD.
