Filter by:This is a PI-initiated study taking place only at UCLA, sponsored by Sunovion. The investigators plan to enroll about 20 subjects who are at least 40 years old and have Chronic Obstructive Pulmonary Disease (COPD). The purpose of this study is to compare the effectiveness of Brovana and Serevent in helping relieve COPD symptoms. Specifically, the investigators are looking at how much and for how long the two drugs can open up the small airways in the lungs. This will be done with breathing tests on all subjects, and with high resolution CT scans on subjects who agree to this optional part of the study. Half of subjects will take Brovana (arformoterol tartrate inhalation solution) for 2 weeks and then Serevent (salmeterol xinafoate inhalation powder) for 2 weeks; the other half will take Serevent the first two weeks and Brovana the second two weeks. All subjects will also take Spiriva (tiotropium) and will be provided with albuterol for immediate relief of symptoms. After a Screening Visit to determine eligibility, subjects will be randomly assigned to receive Brovana or Serevent for the first 2 weeks, complete Test Visit 1, then receive the other study drug for 2 weeks, and finally complete Test Visit 2. Visits will include questionnaires, review of health and medications, and breathing tests before and after taking the study drug. Subjects who agree to be in the sub-study will also undergo CT scans before and after taking the study drug at both test visits.
Rationale: Acute exacerbations are key events in chronic obstructive pulmonary disease (COPD), resulting in poorer quality of life. Causes include irritants, viruses and bacterial pathogens. These exacerbations are often treated with a combination of corticosteroids, bronchodilators and antibiotics, but the benefit of antibiotic therapy remains controversial. Several trials studying antibiotic treatment in AECOPD showed conflicting data, with several large studies failing to demonstrate superiority of antibiotic therapy over placebo. Other trials indicated that antibiotic therapy is effective in patients who have at least two of the following symptoms: increased dyspnoea, increased sputum volume and increased sputum purulence. Ever since sputum purulence has been used as a predictive marker in AECOPD, a strategy that has been integrated in the GOLD guideline for treatment of AECOPD. However, the color of sputum reported by patients is not always reliable and inspection of sputum is not always possible. Several serum biomarkers such as C-reactive protein (CRP) and procalcitonin (PCT) are now available. In a recent trial of doxycycline in addition to systemic corticosteroids for patients hospitalized with AECOPD we found that CRP might be valuable as a marker predictive of response to antibiotic treatment in AECOPD.
The aims of this study are - Demonstrating superior efficacy of Prospan® Hustenzäpfchen compared to Placebo in children suffering from acute bronchitis accompanied by coughing - Characterisation of safety and tolerability of Prospan® Hustenzäpfchen in comparison with placebo.
Mechanically Ventilated patients in the intensive care unit (ICU) often present with fever, and purulent sputum, but without radiological evidence of pneumonia. These patients may have tracheobronchitis. Some suspect that this condition precedes the development of pneumonia. Antibiotic treatment in tracheobronchitis is controversial. The investigators will recruit patients with tracheobronchitis and randomize them into 2 groups. One group will be treated with antibiotics and the other group will serve as control.
The Comprehensive Lung Center (CLC) at the University of Pittsburgh Medical Center (UPMC Health System) provides patients with any type of breathing or lung disorder a full range of diagnostic and therapeutic services. The Emphysema/COPD Research Center (ECRC) is a specialty clinic, within this center, that attempts to advance the understanding of emphysema and to evaluate new therapies for patients with emphysema. The Emphysema Research Registry will enable pulmonary research physicians to: 1) gather information and create a research registry of people who have been diagnosed with emphysema; 2) utilize this research registry with the purpose of conducting research that attempts to advance the understanding of emphysema and to evaluate new therapies; and, 3) use the research registry to identify potential candidates for future research programs. These aims will be achieved by the collection of DNA (genetic material)for analysis and storage in addition to pulmonary function tests and other medical information.
