Filter by:This clinical study is designed to explore dose ranging and identify methods to demonstrate the efficacy of Erdosteine in patients with stable Chronic Bronchitis associated with Chronic Obstructive Pulmonary Disease.
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.
Cigarette smoking causes an increase in inflammation in the lungs. In about 20% of smokers this inflammation leads to damage in lungs including making holes in the lung tissue. This damage can not be repaired and these people find it very difficult to breathe. One of the problems with this disease called chronic obstructive pulmonary disease, or COPD for short, is that by the time patients visit their doctor with symptoms, the damage has already been done. At the moment, there is no way to predict which smokers will go on to develop COPD. The aim of this research is to look at smokers who breathe normally and use an imaging technique called a CT scan, to look at their lungs in more detail. Some of these people will have spots on their scan which may be caused by inflammation. We want to look at the cells at these spots to see if they make more proteins and enzymes that cause lung damage when compared to people that do not have these spots. We would then be able to predict which smokers are likely to develop COPD and treat them early before they have damaged their lungs.
Patients with chronic obstructive pulmonary disease (COPD) that have frequent chest infections are the patients most likely to become worse over time. Why these people are more susceptible to chest infections is not known. One reason might be that the white cells in their lungs called macrophages do not work properly. Normally, these cells remove all the debris inhaled into the lung. This can also include bacteria. In patients with COPD, these macrophages are not able to remove these particles. The research question addresses why this happens
Study objectives: - to document the clinical efficacy of telithromycin(800 mg per day for 5 days) at Test Of the Cure (TOC)visit (D12-D19), in acute exacerbation of chronic bronchitis. - to assess the long-term clinical efficacy of telithromycin by telephone at D25-D35 (V3) - to assess the safety of telithromycin
The purpose of this study is to evaluate the safety and effectiveness of levofloxacin, an antibiotic, compared with cefuroxime axetil, another antibiotic, in the treatment of adults with chronic bronchitis experiencing rapid onset of worsening of symptoms caused by bacteria.
This study evaluates the safety of medicine on COPD (Chronic Obstructive Pulmonary Disease). This study will last up to 56 weeks, and subjects will visit the clinic 16 times. Subjects will be given breathing tests, and will record their breathing symptoms daily on diary cards.
The purpose of this study is to evaluate the safety and effectiveness of levofloxacin, an antibiotic, compared with cefaclor, another antibiotic, in the treatment of adults with chronic bronchitis experiencing rapid onset of worsening of symptoms caused by bacteria.
Identifying the role of antibiotics in the treatment of subjects with a microbiologically documented acute exacerbation of chronic bronchitis (AECB) is the purpose of this clinical trial. The trial has been designed to evaluate the efficacy and safety of faropenem medoxomil versus placebo in the treatment of subjects with microbiologically documented AECB.
This trial is a research drug study to compare the effects of two antibiotics for the treatment of acute exacerbation of chronic bronchitis
