Active clinical trials for "Lung Diseases, Obstructive"

This project has focus on patients in palliation testing a digital platform TelePal.dk.

Chronic Obstructive Pulmonary Disease (COPD) is a debilitating and chronic lung syndrome that causes accelerated lung function decline and death in the 20% of cases. Mostly, the non-adherence to therapy contributes to symptoms increase, mortality, inability and therapies failure, highly influencing the management costs associated to COPD. The existing procedure of diagnosing COPD is effective and fast. The acute treatment and the subsequent disease management, instead, strictly depend on the currently long and complex process of identification of three factors: COPD phenotype, adherence to chosen therapy and probability of exacerbation events. The knowledge of these factors is needed by clinicians to stratify patients and personalise the therapies and rehabilitation procedures, to initiate an effective disease management. The application of Raman spectroscopy on saliva, representing an easy collectable and highly informative biofluid, has been already proposed for different infective, neurological and cancer diseases, with promising results in the diagnostic and monitoring fields. In this project, we propose the use of Deep Learning analysis of Raman spectra collected from COPD patient's saliva to be combined with other clinical data for the development of a system able to provide fast and sensitive information regarding COPD phenotypes, adherence and exacerbation risks. This will support clinicians to personalise COPD therapies and treatments, and to monitor their effectiveness.

A fan blowing cool air to the face has been shown to alleviate breathlessness in malignant and non-malignant disease at rest and during exercise, however the underlying physiological mechanisms remain unknown. This random order, three-condition design study will explore physiological mechanisms of breathlessness relief with fan-to-face therapy during constant-rate exercise in people with cardiorespiratory disease.

This is a prospective interventional study to determine whether the profile of volatile organic compounds (VOCs) present in exhaled air (VOLATOLOM) is reproducible in stable severe COPD (Chronic Obstructive Pulmonary Disease) patients.

Chronicle obstructive pulmonary disease is a worldwide cause of mortality and morbidity. This systemic disease progressively leads to dyspnea, muscle wasting and exercise capacity impairment. Pulmonary rehabilitation is a cornerstone in the management of these systemic effects. Unfortunately, access to pulmonary rehabilitation is limited for many people who would benefit from it, primarily because of a lack of pulmonary rehabilitation and assessment centers. Optimal assessment should include an incremental cardiopulmonary exercise testing. This test allows to evaluate the factors contributing to exercise intolerance by linking performance and physiological parameters to the underlying metabolism. Moreover, it is the standard test to determine both the optimal training settings as well as any cardiopulmonary contraindications to pulmonary rehabilitation. However, this test is not available in most centers and when it is, consultations are limited. Therefore, pulmonary rehabilitation is often delayed for several weeks and patients can lose motivation. In order to promote pulmonary rehabilitation, the incremental cardiopulmonary exercise testing could be replaced by field tests to individualize pulmonary rehabilitation prescription. The six-minute stepper test is a new field tool. Its sensitivity and reproducibility have previously been reported in patients with chronicle obstructive pulmonary disease. It is easy to set up in the clinical setting and could be used to individualize pulmonary rehabilitation. The main drawback when using field test is that they only provide a non specific assessement of the functional capacity because cardiopulmonary parameters and gaz exchanges are not monitored. Although the performance during the 6-minute stepper test is moderately related with the maximal oxygen consumption during the incremental cardiopulmonary exercise testing performed on a cycloergometer, a direct comprehensive comparison of cardiopulmonary parameters and gaz exchanges during these two tests have never been performed. Moreover, stepping is more closely related with activities of daily life (requiring a repetitive transition from rest to submaximal exercise intensity) than the maximal incremental exercise on cycloergometer and could provide further insight on the disability of patients during their usual activities, such as stair climbing (which is frequently avoided). Additionally, on-transient phase two oxygen consumption kinetic is particularly relevant because it evaluation is independent of the patient's motivation or criteria used to terminate exercise. Therefore, the aim of this study is to compare the cardiorespiratory parameters, the gaz exchanges and the maximality between the six-minute stepper test and the incremental cardiopulmonary exercise testing performed on a cycloergometer. The secondary objective was to compare the on-transient oxygen consumption phase two kinetic parameters (time constant, span and steady state) according to the severity of the disease.

The main objective of this study is to assess the effects of a myofascial release protocol in patients with chronic obstructive pulmonary disease (COPD).

This study will last for 5 years (2021.2.25-2025.12.31). 210 patients (70 cases in each group) will be enrolled in this study. Eight centers in China will participate in the study. The patients will be treated with bronchoscopy alveolar lavage, and 60 ml of bronchoalveolar lavage fluid will be collected for the next-generation sequencing of airway microorganisms. The patients will be followed up for 4 years to observe the changes of lung function, Fractional exhaled nitric oxide (FENO) and clinical symptoms.

It has been observed in the literature that respiratory muscle electromyography activations at certain threshold loads have been examined in individuals with chronic obstructive pulmonary disease. However, no study has been found in the literature examining the acute effects of respiratory muscle training given at low, medium and high threshold loads on respiratory muscle activations. With this planned study, it is aimed to examine the electromyography activations of respiratory muscles before and after respiratory muscle training and to contribute to the literature by comparing the acute effects of respiratory muscle training applied at low, medium and high intensity on respiratory muscle electromyography activations.

This will be a prospective study examining serum levels of MMP-13 and alpha-1 antitrypsin as well as other biomarkers as well as urine biomarkers of smoking status and collagen degradation in the COPD patient population. Serum and urine biomarkers at baseline and after COPD exacerbations will be assessed against change in lung function as measured by pulmonary function testing.

Exacerbations of chronic obstructive pulmonary disease (COPD) are unfavourable events in the course of disease for most COPD patients. Published evidence indicates a significant impact of exacerbations, especially if frequent, on patients' health-related quality of life (HRQL), disease progression, mortality, health care utilisation and costs. However, the severity,evolution and outcome of an exacerbation may differ significantly between patients - some patients will recover completely in a short period of time while others may die. The identification of risk factors for an adverse outcome could help in distinguishing patients who require more intense management in order to prevent failures, achieve satisfactory recovery and reduce the negative clinical and socioeconomic impact of exacerbations.The pathogenesis of COPD is still unclear, so there is no specific treatment at present .COPD was considered to be the result of a combination of environmental and genetic factors. Genetic factors play an important role in the acute exacerbation of COPD.Therefore, it is an urgent need to explore the heterogeneity of COPD phenotype from the perspective of genes and to seek individualized prevention and treatment programs.This study is intended to provide a theoretical basis for the prevention, evaluation and development of individualized treatment plans for acute exacerbation of COPD, thereby improving the prognosis of the disease.
