Active clinical trials for "Lung Diseases"

This is a clinical research study to assess whether after exhaling a single cigarette smoke through the nose there are changes in the inflammatory cells and proteins of nasal secretions. A single blood sample from each subject will be stimulated with cigarette smoke in the laboratory to see the effects on inflammatory blood cells. Comparison of findings between smokers with COPD and "Healthy" smokers will be carried out. We hypothesize that some subjects have amplified inflammatory response to a single cigarette, and these will be those subjects who develop chronic obstructive pulmonary disease (COPD) after decades of smoking. We hope to develop an acute challenge model that relates to the causation of COPD. When studying the effects of new drugs, these may be detected in small numbers of patients in a challenge situation, when we would need to study many more unchallenged patients to demonstrate drug effects. In clinical research on asthma and allergy, the nasal allergen challenge has been a very successful model, and we hope to validate a comparable model for COPD.

The study has two objectives/aims: Aim 1: To test the efficacy of the intervention among adult smokers with cardiovascular disease, pulmonary disease and diabetes mellitus related illnesses (later modified to Chinese adults with and without diseases); and Aim 2: To examine a set of measures (background, general health, psychosocial, and smoking process) that are associated with smoking cessation at 6 and 12 months

To evaluate the efficacy and safety of cyclophosphamide versus placebo for the prevention and progression of symptomatic pulmonary disease in patients with systemic sclerosis.

This study will establish a network of interactive asthma clinical research groups to evaluate current therapies, new therapies, and management strategies for adult asthma.

This research study compares two ways to biopsy lymph nodes in the chest using endobronchial ultrasound-guided transbronchial needle aspiration" (EBUS-TNBA). During a EBUS-TBNA procedure, the patient is sedated, and a flexible camera and ultrasound probe is inserted through the mouth into the large airways of the chest, allowing us to see (via ultrasound) and biopsy the lymph nodes in the chest. The purpose of this research study is to determine if the EBUS-TBNA procedure can be made simpler. In today's practice, the biopsy needle has two parts, 1) the needle itself and 2) an inner stylet that runs through the middle of the needle. Because many other biopsy needles (such as the needles used in breast biopsy and different types of lung biopsy needles) do not use an inner stylet, the investigators do not think the use of a stylet is necessary. If this step can be safely eliminated without decreasing the effectiveness of the procedure, this could shorten the procedure (saving time). This study is deigned to formally test the hypothesis that a stylet is not necessary in EBUS-TBNA.

Randomized, placebo controlled trial evaluating efficacy of dexamethasone in preventing sleep related breathing disturbances in lowlanders with chronic obstructive lung disease travelling from 700 m to 3200 m.

The objective of this study is to compare the sample size, architectural preservation and diagnostic yield of bronchoscopic cryo-probe transbronchial lung biopsy (C-TBBx) to bronchoscopic standard transbronchial lung biopsy (S-TBBx) and Video-Assisted Thoracoscopic Surgery (VATS) lung biopsy for the diagnosis of interstitial lung disease (ILD).

The purpose of this study is to assess whether 6% hypertonic saline (HS) is a safe and effective preventive therapy in newborns and infants with cystic fibrosis (CF).

This study will compare the efficacy of indacaterol versus placebo (i.e., rescue medication only) and tiotropium in patients with Chronic Obstructive Pulmonary Disease (COPD) who have not received maintenance COPD medication for at least 12 months prior to entry (described hereafter as "maintenance naïve", see inclusion criteria).

To study the effects of early exercise training in hospitalized patients for Chronic Obstructive Pulmonary Disease exacerbation (COPD). Interventions are randomized. In one group, early exercise training (aerobic and strength) during hospitalization for COPD exacerbation followed by exercise training at home until 30 days to discharge and in the other the intervention is usual care. In both groups, usual respiratory physiotherapy techniques during hospitalization and adequate physical activity recommendations have been included. The main variable is the increase in moderate or vigorous daily physical activities at 30 days after discharge.
