Active clinical trials for "Lung Diseases"

The aim of this study is to provide high quality data and give a comprehensive overview of characteristics, clinical features, management and prognosis during exacerbations and stable periods among inpatients with acute exacerbation of chronic obstructive pulmonary disease in real-world China.

Chronic obstructive pulmonary disease (COPD) and bronchiectasis are common chronic respiratory diseases in China. COPD is characterized by irreversible lung function decline due to airway inflammation, emphysema and alveolar destruction. Bronchiectasis is characterized by permanent bronchiectasis, its main clinical symptoms are cough, dyspnea, hemoptysis and recurrent respiratory tract infections. The incidence and prevalence of bronchiectasis have assumed continuously grows in global. Airway microbiota, whose alterations play an important role in the occurrence and development of bronchiectasis, form a complex ecosystem interacted with host cells and various biotic and abiotic factors in the microenvironment. Additionally, mounting evidence suggests that the airway microbiome is associated with COPD phenotypes and endotypes, and that dysbiosis contributes to airway inflammation. However, the mechanisms remain poorly understood, owing to limited knowledge of microbial functional properties, metabolic activities and cross-talk with the host immune system. The investigators aim to collect sputum specimen and perform multi-omic analysis on patients with COPD and bronchiectasis in seven clinical centres in China.

The goal of this observational study is to learn about risk of progressive pulmonary fibrosis (PPF). The main questions it aims to answer are: Risk factors of PPF Prevalence of PPF Mortality of PPF Patients with interstitial lung disease (ILD) of known or unknown etiology other than IPF who has radiological evidence of pulmonary fibrosis will enroll in this study. All participants will have baseline investigations at the first visit having provided informed consent. At the first visit, baseline characteristics will be collected including demographics, medical history, smoking history, complications and medication use. 50 mL of blood will be obtained. High resolution computed tomography (HRCT), full lung function tests and a 6 min walk test will be performed. Further visits at 6 months and 12 months will include further 50 mL blood sampling. HRCT, full lung function tests and a 6 min walk test will be repeated.

Chronic respiratory diseases (CRDs) affect the airways and other structures of the lungs and thereby lead to ventilation inhomogeneity. The most common CRDs in children are asthma, bronchiectasis and cystic fibrosis (CF). All three are obstructive diseases. However, while asthma is mostly characterized by obstruction due to bronchoconstriction of the airways, obstruction in bronchiectasis and CF originates primarily from mucus retention due to abnormal airway clearance mechanisms. The Nitrogen Multiple Breath Washout test (N2-MBW-test) is a robust and sensitive detector of early pulmonary changes and ventilation inhomogeneity. The minimal cooperation which is required for this test makes it very convenient for use in any age category. Research on LCI described it as a reliable indicator of obstructive lung disease in pediatric CF patients as from 6 years of age. Whether LCI is a reliable parameter for early lung disease in asthma children is less clearly demonstrated. No data were found on LCI calculated from the N2-MBW-test in children with bronchiectasis.

For many patients with blood cancers, stem cell transplantation from a family member or from an unrelated donor remains the only potentially curative option. Unfortunately, up to 40% of patients develop chronic lung disease after the transplant, which substantially increases the risk of death in the long-term. Currently, patients with transplant-related lung disease are treated with some combination of steroids and other immunosuppressant drugs, but only about 1 out of 5 improve. The importance of our study is that the investigators aim to prevent the development of transplant-related chronic lung disease in the first place. Because a strong risk factor for such chronic lung disease is a prior viral respiratory tract infection, the investigators think there is a window of opportunity to intervene. As soon as "cold and flu" symptoms start, the investigators will treat patients with a combination of drugs aimed at eliminating damaging immune responses triggered by the virus. In the absence of such treatment, the investigators believe these lung-damaging immune responses would persist even after the virus disappears. Our hope is that preventive treatment might avoid the development of chronic lung disease, and this would substantially increase long-term survival in our transplant patients. This is a pilot study. Once feasibility is established, the investigators will seek to expand this study into a definitive clinical trial.

This study will last for approximately 8 weeks and will involve 4 visits. The study is being carried out to validate a shortness of breath questionnaire

The purpose of the study is to examine the hypothesis test that probiotics will reduce the frequency of exacerbation in patients with COPD.

Aims and objectives: To determine the effect of foot bath on sleep quality and fatigue level in patients with chronic obstructive pulmonary disease (COPD). Background: İnsomnia and fatigue are one of the most common symptoms in people with COPD and adversely affects their activities of daily living. Design: This study was conducted as a nonrandomized controlled trial. Methods:The study sample comprised 70 patients who met the inclusion criteria.Data were collected with Patient Information Form, Pittsburgh Sleep Quality Index and Piper Fatigue Scale. Intervention group; The 30-day foot bath was administered for 10 minutes before bedtime, while no control was performed in the control group. The Pittsburgh Sleep Quality Index (PUKI) and the Piper Fatigue Scale were administered in both groups at the beginning of the service (first follow-up) and four weeks later (second follow-up) at the outpatient clinic. Conclusions: The foot bath by individuals with COPD was determined to significantly improve the participants'levels sleep quality and fatigue.

The goal of this prospective randomized controlled study is to explore the clinical efficacy of acupuncture therapy combined with breathing training in patients with stroke complicated with pulmonary infection. The intervention group and control group were treated with conventional drug therapy, rehabilitation therapy and breathing training for 2 consecutive weeks. On this basis, the intervention group additionally received acupuncture therapy. To evaluate the clinical efficacy of both groups.

The goal of this clinical trial was to compare the action of long-acting ß2-agonists (LABA-olodaterol) and muscarinic antagonists (LAMA-tiotropium) on tissue oxygenation in COPD considering their impact on proximal and peripheral ventilation and, eventually, on lung capillary volume. The hypothesis was that LABA would have a more peripheral effect than LAMA (due to the opposite gradient of their receptors) and better peripheral ventilation would result in a greater oxygenation. Before and after LABA (visit 1) and LAMA (visit 2) inhalation, COPD participants were asked to perform single-breath washout and forced oscillation tests, double diffusion technique and spirometry, while transcutaneous oxygenation was continuously recorded.
