Filter by:The purpose of this study is to obtain young white blood cells (monocytes) from the investigators donated blood for research into how these cells change into large, mature white blood cells (macrophages) and how smoking causes Chronic Obstructive Pulmonary Disease (COPD).
The purpose of this study was to evaluate the efficacy, safety, and tolerability of single doses of trospium inhalation powder (TrIP) administered to subjects with chronic obstructive pulmonary disease (COPD).
This clinical trial will include healthy volunteers, COPD patients and asthmatic patients who will breathe He/O2 78:22, He/O2 65:35 and medical air consecutively in a randomised order.
The purpose of this study is to evaluate the duration of oxygen use recorded by the NOWOX, under usual conditions of daily living, in patients with chronic obstructive respiratory disease requiring oxygen therapy.
The aim of the study is to assess the correlation between airflow limitation, perception of dyspnea and functional capacity with anatomic changes in pulmonary structure as seen on High Resolution CT in COPD patients.
This study was designed to provide pivotal confirmation of efficacy and safety data for 2 doses of indacaterol (150 and 300 µg once daily [od]) in patients with moderate to severe chronic obstructive pulmonary disease (COPD). Data from this study will be used for the registration of indacaterol in Japan.
The G protein-coupled receptors (GPCRs) are a family of proteins expressed at the cell membrane. They are composed of 380 members involved in the important functions of the organism and are privileged therapeutic targets.Their expression is highly modulated depending on the metabolic state of the cells, in particular in pathological situations.our study proposes to determine whether GPCR expression modulation could be used as a biomarker, either prognostic or diagnostic, of treatments.To do so , the investigators will determine the expression profile of the 380 human GPCRs in human blood cell samples in two chronic inflammatory pulmonary diseases : asthma and COPD (chronic obstructive pulmonary disease ) . These have opposed inflammatory infiltrates : asthma is associated with eosinophil and Th2 lymphocyte infiltration whereas COPD shows neutrophils and macrophages within the airways with a Th1 lymphocytic population. The GPCR signature (transcriptomic) will be determined on total white blood cells as well as on isolated mono- and poly-nuclear populations obtained from healthy subjects and patients selected at the asthma or COPD consultation. The expression profiling analysis will reveal sub-groups of GPCRs whose expression is modified in disease. The specificity of the variation of expression of these biomarker sub-populations will be determined, by a study recruiting a hundred patients and controls per disease on this restraint number of genes. The outcomes of the project will lead to establish GPCR "identity cards" for these chronic inflammatory diseases, which might therefore be used as diagnostic or prognostic biomarkers to follow the evolution of a disease or the efficacy of a given treatment. In addition, detailed analysis of the identified GPCRs will lead to propose new therapeutic targets for inflammatory diseases. This study has therefore the objective of validating GPCRs as potential biomarkers for inflammatory diseases.
The aim of the study is to develop an interview to ask patients with COPD about their fear of death and dying, their needs and wishes at the end-of-life. Afterwards, the patients receive a brief psychological intervention to develop coping strategies for chronic illness. Beside this a general purpose of this intervention is to improve patients' quality of life.
This study evaluated the efficacy and safety of two doses of indacaterol in adults aged 40 or over with chronic obstructive pulmonary disease (COPD) in China and in two other countries.
Although the use of antibiotics in the treatment of acute exacerbation of chronic obstructive pulmonary disease (COPD) is largely accepted, controversy remains regarding whether the choice of antibiotic has any impact on outcome. Our aim was to compare the effects of the combination of trimethoprim and sulfamethoxazole and ciprofloxacin in patients treated for severe COPD exacerbation requiring mechanical ventilation.
