Active clinical trials for "Bronchitis"

The Comprehensive Lung Center (CLC) at the University of Pittsburgh Medical Center (UPMC Health System) provides patients with any type of breathing or lung disorder a full range of diagnostic and therapeutic services. The Emphysema/COPD Research Center (ECRC) is a specialty clinic, within this center, that attempts to advance the understanding of emphysema and to evaluate new therapies for patients with emphysema. The Emphysema Research Registry will enable pulmonary research physicians to: 1) gather information and create a research registry of people who have been diagnosed with emphysema; 2) utilize this research registry with the purpose of conducting research that attempts to advance the understanding of emphysema and to evaluate new therapies; and, 3) use the research registry to identify potential candidates for future research programs. These aims will be achieved by the collection of DNA (genetic material)for analysis and storage in addition to pulmonary function tests and other medical information.

The aim of the study is to determine the importance and impact of resistive breathing techniques versus inspiratory hold techniques in patients with chronic bronchitis and specially to find out if there are any changes seen in results measured via the incentive spirometer.

Cross-over trial of the effect of a salt particle inhaler on pulmonary muco-ciliary cleansing in COPD patients as measured by lung scintigraphy.

The purpose of this study is to examine the implementation, intervention effectiveness, and dissemination of a digital acute care delivery model for improving selected health outcomes in the Hospital at Home population.

Monitoring patients with chronic, inflammatory airways disease particularly in the early stages is hampered by the relative insensitivity of current outcome measures to detect subtle changes. Multiple breath washout is a potential sensitive test that is a useful readout of disease at these early stages but it lacks standardisation and knowledge of variability with reference to standard lung function measures. This is a Cross sectional and longitudinal observation study. The hypothesis is that multiple breath washout-derived indices will provide a robust signal of gas mixing inhomogeneity, correlating with conventional measures of airway disease severity. Multiple breath washout performed on different devices will generate indices which correlate but differ in value.

Obstructive lung disease is an increasing global health problem of pandemic proportions, with COPD alone affecting >10% of the population. Smoking is the main and most well studies risk factor for developing COPD. However, chronic airway obstruction also in never-smoking populations has recently been recognized as an increasing health problem. In the clinical segment (PI: Prof. C. Magnus Skold), 1000 subjects from the Swedish national SCAPIS study will be clinically well characterized in one of the six Swedish University Hospital Respiratory clinics (clinical site PIs: Anders Andersson, Leif Bjermer, Anders Blomberg, Christer Janson, Lennart Persson, Magnus Skold). This first screening includes all never-smokers with COPD identified in the SCAPIS study. A subset of 300 subjects from the groups of Healthy never-smokers, current-smokers with normal lung function, current-smokers with COPD, ex-smokers with COPD, and never-smokers with COPD will be selected for the Bronchoscopy segment, were sampling will be performed from a number of anatomical locations, including bronchial biopsies, airway epithelial brushings, and bronchoalveolar lavage. Serum, plasma, and urine samples will also be collected. In the systems medicine segment (PI: Assoc. prof Asa M. Wheelock), alterations at the epigenetic, mRNA, microRNA, proteome, metabolome and microbiome level will be performed from multiple lung compartments (airway epithelium, alveolar macrophages, exosomes, and bronchoalveolar exudates). By means of biostatistics and bioinformatics approaches, specific mediators and molecular pathways critical in the pathological mechanisms of obstructive lung disease related to never-smoker disease phenotypes will be identified. In the immunohistochemistry segment (PI: Prof. Jonas Erjefalt), a number of molecules of relevance for disease pathology will be investigated in bronchial biopsies collected from the 300 subjects in the Bronchoscopy segment.

Ivermectin is currently being utilized by a number of physicians in the local area. My objective will be to enroll these patients at the time of their evaluation for COVID-19 infection and to follow their progress through their recovery.

The COPD Patient-Powered Research Network (COPD PPRN) is a patient research registry with the goal of enrolling 75,000 or more COPD patients and those at risk who are willing to share their heath information over several years and participate in research. The COPD PPRN has built an online platform to allow volunteers to enroll electronically, complete surveys, be contacted about studies they qualify for and become connected to COPD resources. The goal of the registry is to speed research to find better treatments for COPD and ultimately a cure.

SPIROMICS I and SPIROMICS II are observational studies of Chronic Obstructive Pulmonary Disease (COPD). SPIROMICS I had two main aims: (1) To find groups of patients with COPD who share certain characteristics; (2) To find new ways of measuring whether or not COPD is getting worse and so provide new ways of testing whether a new treatment is working. SPIROMICS II has three primary aims. Aim 1 is to define the natural history of "Smokers with symptoms despite preserved spirometry" and characterize the airway mucus abnormalities underlying this condition. Aim 2 is to determine the radiographic precursor lesion(s) for emphysema, and identify the molecular phenotypes underlying airway disease and emphysema. Aim 3 is to advance understanding of the biology of COPD exacerbations through analysis of predisposing baseline phenotypes, exacerbation triggers and host inflammatory response.
