Filter by:This study evaluates if motivational interviewing sessions aiming to motivate recently discharged patients with either chronic obstructive pulmonary disease or congestive heart failure to be active in post-discharge self-management can reduce re-hospitalization rates.
To compare the clinical outcomes of Endoscopic Lung Volume Reduction using Pulmonx Zephyr Endobronchial Valve (EBV) vs. Standard of Care (SoC) in the treatment of heterogeneous emphysema patients in a controlled trial design setting.
Chronic Obstructive Pulmonary Disease (COPD) is characterized by chronic systemic hypoxia and low-grade inflammation as well as by an alteration of arginine (ARG) metabolism. As ARG is synthetized from circulating citrulline (CIT), an alteration of CIT homeostasis, particularly its production by ornithine transcarbamylase (OCT) in small intestine could be involved. We hypothesized that hypoxia +/- inflammation, classically associated to COPD, has effects on OCT regulation in enterocytes. This study aims at exploring the effects of hypoxia and inflammation on the production of citrulline by ornithine transcarbamylase (OTC) activity in enterocytes from explant cultures of duodenal tissue.
Aerosol delivery through a ventilator is influenced by numerous factors from ventilator-related, circuit-related to device-related factors. Aerosolized drug delivery through a ventilator system was studied on bench model with albuterol, yet the results were often overestimated. The objective of this study was to evaluate inhaled bronchodilator and mucolytic agents delivered through a ventilator system.
Positive expiratory pressure (PEP) therapy is a device aiding airway clearance and secretion mobilization, also prevent the small airway from collapsing. The purpose of this research is to compare two PEP devices (Pulmonica, RC-Cornet) in stable COPD patients. Patients' compliance, satisfaction, 3 months and 6 months lung function test and life quality will be compared.
Chronic obstructive pulmonary disease (COPD) is a common disease worldwide with a high burden on healthcare resources. The prevalence of COPD varied from 11.4 to 26.1% according to a recent multi-city population study using spirometry. In Hong Kong (HK), the prevalence rates of COPD in the elderly population aged ≥60 years were 25.9% and 12.4% based on the spirometric definition of forced expiratory volume in 1s (FEV1)/forced vital capacity (FVC) ratio <70% and the lower limit of normal of the FEV1/FVC respectively. In 2005, the crude mortality rate of COPD was 29.1/100 000, while the crude hospitalization rate was 193/100,000 in HK. In HK, COPD ranked second as a respiratory cause for hospitalization. In those 75 years or older, the hospitalization rate for COPD was as high as 2,225/100,000. The economic burden of COPD on the society is enormous. Previous studies gave information on the overall morbidity, mortality and the prevalence of COPD in HK. One study compared the management of COPD patients in HK with other countries and found that COPD patients in HK were under-treated. No large scale study has looked into the details of COPD patients in HK, like their co-morbidities and how they are being treated and how these factors affect the readmission of these patients. Large prospective studies which incorporate all the potentially relevant variables are required to refine prediction of the important outcomes of AECOPD and thus to inform clinical decision making, for example on escalation of care, facilitated discharge and provision of palliative care.
Rationale: New bronchoscopic treatments for emphysema have shown promise in clinical trials, improving lung function, exercise capacity and possibly survival and are now being adopted by a number of centres in the Netherlands. It is important to ensure that the benefits seen in clinical trials are in fact reflected in clinical practice and that the best use of this early 'real world' experience is made to optimise the development and use of these novel therapies. Overall objective: to develop a national database to record bronchoscopic lung volume reduction procedures for patients with emphysema. This is desirable for audit purposes but will also be an important resource for research both in gathering data and in facilitating collaborations.
CHF6297 is a potent and selective inhibitor of human MAP kinase p38 being developed as an anti-inflammatory agent for the treatment of inflammatory airways diseases. The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of single and repeat doses of CHF6297 as dry powder formulation in healthy subjects and in COPD patients. This study is the first administration in humans. The study will comprise four parts: Part 1 will consist of two cohorts of healthy male subjects to assess the safety, tolerability and pharmacokinetics of Single Ascending Dose (SAD) of CHF6297. Part 2 will consist of four cohorts of healthy male subjects to assess the safety, tolerability and pharmacokinetics of Multiple Ascending Dose (MAD) of CHF6297. Part 3 will consist of one cohort of COPD patients to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of a repeat dose of CHF6297 Part 4 will consist of one cohort of healthy subjects to assess the anti-inflammatory effect of a repeat dose of CHF6297 after LPS challenge.
AZD8871 is a new chemical entity possessing long-acting effect in a single molecule which presents a novel treatment approach to chronic obstructive pulmonary disease [COPD] and potentially also asthma (in combination with an inhaled corticosteroid [ICS]). The therapeutic goal for AZD8871 is a treatment with greater efficacy than single mechanism bronchodilators, with an equivalent or superior safety and tolerability profile. The primary purpose of this study is to check the safety and tolerability of AZD8871 at steady state. A multiple ascending dose (MAD) design has been selected for this study following the first time in man (FTIM), single ascending dose (SAD) study. Three dose levels will be tested in an ascending manner. The first dose to be administered will be 300 μg and the 2 subsequent doses will be decided based on safety, tolerability and pharmacokinetic (PK) data generated in the previous dose. The aim of this study is to also enable further investigations in healthy subjects to evaluate and develop AZD8871 as a dual action bronchodilator with an acceptable side-effect profile compared to other inhaled bronchodilators on the market as a treatment for COPD and asthma.
Objective: Determine whether treatment of perceived stress, anxiety, and depression with anti-depressant therapy improves dyspnea scores, 6-minute walk (6MW) distance and quality of life (QoL) in patients with Chronic Obstructive Pulmonary Disease (COPD) and ILD (Interstitial Lung Disease) undergoing pulmonary rehab. The study is a prospective, randomized, double-blinded, placebo-controlled study to assess the effect of an SSRI on 6MW, dyspnea scores, and QoL in COPD and ILD patients undergoing pulmonary rehab. Thirty subjects that carry an ICD-9 code diagnosis of COPD and/or ILD and CES-D (Center for Epidemiologic Studies Depression) score of > 16 will be recruited from Duke Pulmonary Rehab. Multivariable regression models will be constructed to evaluate the relationship between perceived stress, anxiety, and depression with adjustments by race, gender, age, BMI and GOLD score. A multivariable regression model will be constructed to assess whether treatment of perceived stress, depression, and anxiety with antidepressant therapy (sertraline) is an effect modifier on 6MW distance and dyspnea scores in patients with COPD or ILD who are enrolled in pulmonary rehab. Descriptive statistics will be used to examine the socio-demographic characteristic data. Student t-tests will be performed to assess group differences in continuous data. Categorical variables will be examined using the Pearson's Chi-Squared test.
