Filter by:Aim of this study is to compare the effects of whole-body Vibration Training versus conventional Balance Training on Balance performance, gait quality and exercise capacity in patients with severe chronic obstructive pulmonary disease. Patients will be recruited during a 3-week inpatient pulmonary rehabilitation program and will be randomized into one of two intervention groups. On top of a standardized endurance and strength Training program (5 days per week) patients in both groups will perform an additional Balance Training (on 3 days per week). Patients in both Groups will perform the same 4 different Balance exercises (2x1 Minute each): dynamic squats with closed eyes, heel raise, semi-Tandem stance and single leg stance but on a different surface. The Vibration Training Group will perform the exercises on a side-alternating Vibration platform (Galileo) at frequencies between 15 to 26 Hertz and the control Group will perform exercises on instable objects like Balance pads. The degree of difficulty in both Groups will be individually adjusted and will be progressively increased, if possible.
Investigation into the associations between sedentary behaviour, physical activity, body composition and cardiometabolic risk in COPD. A single assessment visit with fasting blood tests, body composition and strength measures followed by a week of activity monitor wear to record sitting time and physical activity. Cardiometabolic risk markers include fasting glucose, HBA1c, HOMA and lipids and blood pressure.
Bronchial basal cells are proved to be able to regenerate lung structures to repair the injured lung. In COPD patients, bronchus structures are injured and cannot be repaired, which may result in the failure of pulmonary function rescue clinically.In our research, autologous bronchial basal cells will be transplanted into lung of patients suffered with COPD to treat the disease. Specifically, autologous bronchial basal cells will be dissected from brushed-off samples by bronchofiberscope. Then, they will be expanded in vitro and transplanted into lung to regenerate new alveoli and bronchus structures and re-establish pulmonary system.
Randomized, placebo controlled trial evaluating efficacy of acetazolamide in preventing altitude related adverse health effects (ARAHE) in lowlanders with chronic obstructive lung disease travelling from 760 m to 3200 m.
Chronic Obstructive Pulmonary Disease (COPD) is characterized by persistent airway obstruction and inflammatory response of the lungs and bronchi. Episodes of exacerbations contribute to increase the severity and prognosis of the disease. Muscle dysfunction (loss of strength and muscle mass) is one of comorbidities affecting 30% to 60% of patients and playing a key role in their prognosis. Indeed, several studies have shown muscle weakness during hospitalization for exacerbation of COPD by measure of maximal voluntary contraction of quadriceps (MVCQ), but the results are variable from one patient to another. Moreover, no study was interested in the change of muscle mass in patients hospitalized for an exacerbation of COPD. Several mechanisms have been mentioned but not demonstrated: systemics factors (initial amyotrophy, inflammation, oxidative stress, corticotherapy, hypoxia…) but also physical inactivity. In this context, identifying factors associated with the onset of muscle weakness during hospitalization for exacerbation of COPD is a necessary step to better understand the mechanisms and consider a personalized therapeutic approach that can improve the functional and clinical prognosis of disease. The primary outcome is to identify the clinical and biological determinants associated with the onset of amyotrophy (Measure by ultrasound of sectional area of the Rectus Femoris, CSARF), during hospitalization for exacerbation of COPD. The secondary outcome is to identify the clinical and biological determinants associated with the onset of MVCQ decrease, during hospitalization for exacerbation of COPD. 120 patients hospitalized for exacerbation of COPD will be recruited in two hospitals (CHU Montpellier - CHU Grenoble, FRANCE). The measures of CSARF and MVCQ are carried out on the second, fifth, eighth day of hospitalization, on discharge and on the sixtieth day after hospitalization. A blood test will be performed on the second day of hospitalization to explore different markers of inflammation and oxydative stress. Moreover, to quantify the level of physical activity (number of steps), each patient will carry a pedometer throughout the duration of hospitalization. At the end of protocol, two groups will be made from the median of CSARF : patients with a small reduction in CSARF compared to patients with a greater reduction in SSRF between the second and eighth days of hospitalization (or between the second day of hospitalization and discharge). Then clinical (comorbidities, severity disease, initial weakness, initial amyotrophy, usual physical activity before hospitalization, treatment, exacerbation number in the previous year…) and biological (markers of inflammation and oxydative stress) determinants were compared between the two groups. Thus, the identification of the determinants associated with the onset of amyotrophy induced during exacerbation of COPD will guide research for exploration of physiopathological mechanisms of this muscular dysfunction in the exacerbation of COPD as well as to identify a personalized support.
Chronic obstructive pulmonary disease(COPD), characterized by persistent airflow limitation, associated with an progressive chronic inflammatory response of the lung to noxious particles or gases, can lead to dyspnea and limited mobility and influence the life quality of patients severely. Type 2 diabetes mellitus(T2DM), as a common complication of COPD, has got more attention in comprehensive control of COPD. Stress response and metabolic disorder are more likely to happen in COPD patients with T2DM in high level inflammation status, which decrease the drug efficacy, increase the risk of acute exacerbation of COPD, complications and mortality. Both COPD and T2DM are chronic inflammatory disease with long term, there is close relationship in occurrence and development of each other, and the patients with severe COPD are more likely to develop T2DM. Monitoring the acute inflammation maker of C reactive protein (CRP) and IL-6(interleukin-6) is the most useable way to predict the inflammatory status and condition of COPD patient with T2DM, however the chronic inflammation maker is lacking. Neutrophil-to-Lymphocyte ratio(NLR), platelet-lymphocyte ratio (PLR) and lymphocyte-monocyte ratio (LMR) , the new, cheap and easy-tested chronic inflammatory markers, have got great research in early predicting the tumor such as nasopharyngeal carcinoma, soft tissue sarcoma and small-cell lung cancer,among them, NLR has manifest promising application in predicting insulin-resistance. However the value about NLR,PLR and LMR to predict the T2DM in COPD patients remain unknown and many articles related to NLR and COPD are retrospective. The investigators attempt to analyze the risk factors and predict value of NLR,PLR and LMR about developing T2DM in COPD patients with prospective method.
This protocol describes a randomised controlled trial to test the hypothesis that 6 months of treatment with tiotropium and olodaterol will result in a reduction in bacterial load, an improvement in neutrophilic inflammation and clinical benefits compared with treatment with inhaled fluticasone furoate and vilanterol in patients with neutrophilic Chronic obstructive pulmonary disease (COPD). COPD is the third leading cause of death worldwide and a major cause of morbidity in the UK. Exacerbations drive disease progression and worsening quality of life and therefore prevention of exacerbations has been a major goal of treatment. In recent years, attempts have been made to phenotype COPD patients in order to target therapies to the correct groups of patients that will benefit. Inhaled corticosteroids (ICS) are primarily effective for patients with eosinophilic inflammation, while there are few established therapies for patients with neutrophilic disease. In recent years, all ICS preparations have been associated with a significant increased risk of pneumonia and this risk appears to be greatest in patients with non-eosinophilic inflammation. Combined treatment with long acting beta-agonists (LABA) and long acting muscarinic antagonists (LAMA) combinations appears to be a safer and more effective alternative for patients with non-eosinophilic disease. The combination of tiotropium and olodaterol in particular, has strong preclinical data supporting beneficial effects on neutrophilic inflammation. The trial is a multi-centre randomised open label controlled parallel group study with two treatment arms in 80 participants. Moderate to very severe COPD patients and currently treated with inhaled corticosteroid therapy will be randomised to treatment with either the combination of tiotropium and olodaterol (LABA/LAMA) or fluticasone furoate and vilanterol (ICS/LABA). Participants will return at 1 month, 2 months, 3 months and 6 months for sampling of the lower airway by sputum samples and the upper airway using oropharyngeal and nasopharyngeal swabs. Sputum will be used to test for airway neutrophilic inflammation. This study will make an important contribution to understanding "phenotyping" in COPD by identifying whether the combination of tiotropium and olodaterol improves airway bacterial load and restores neutrophil function in patients with neutrophilic COPD.
The aim of this study is to investigate the association between endothelial dysfunction, measured by RHI as assessed by the peripheral arterial tonometry method, and PE complications defined as re-event of PE or DVT, systemic embolism or all-cause mortality
This is a Phase 2, multicenter, multinational, randomized, double-blind, placebo-controlled study evaluating the efficacy, safety, pharmacokinetics (PK), quality of life and exploratory pharmacodynamics (PD) of two treatment doses of CC-90001, 200 mg and 400 mg, compared with placebo, when delivered once daily per os (PO) in subjects with idiopathic pulmonary fibrosis (IPF). This study is designed to assess response to treatment by using measures of lung function, disease progression, fibrosis on radiography, and patient-reported outcomes. It will also assess dose response.
