Filter by:The purpose of this retrospective, non-interventional sutdy is to compare the effectiveness of ICS/LABA combination therapy in the reduction of COPD exacerbations during the 12 months after initiation of therapy between COPD patients who are adherent to the index medication and those who are non-adherent.
Longitudinal cohort study of older-aged people living with HIV infection in southwestern Uganda and age and gender-matched HIV uninfected controls with the primary aim of measuring the epidemiology of cardiovascular and pulmonary disease in this study setting, and particularly the contribution of HIV infection to it.
This mechanistic study is a single-center, randomized, double-blind, placebo-controlled, cross-over study to evaluate the effect of dual bronchodilation with QVA149 on cardiac and lung function parameters in hyperinflated COPD patients.
This is a study to provide an in-depth validation of the 1-minute sit-to-stand test as a measure of exercise capacity in patients with chronic obstructive pulmonary disease (COPD). Patients will perform the 1-minute sit-to-stand test and other validated exercise tests and questionnaires.
The main oxygen therapy to the patients with acute exacerbation of Chronic obstructive pulmonary disease, who are mild to moderate respiratory insufficiency (arterial blood gas analysis showed pH = 7.35, PO2 < 60mmHg,PaCO2＞45mmHg) or have achieved the traditional noninvasive ventilation support standard but can not tolerate or reject, was nasal catheter, venturi mask and other conventional oxygen therapy. All these inaccurate inhaled oxygen concentration methods with inadequate heating and humidifying lead to poor patient tolerance and adverse reactions such as airway secretions discharge disorders. The high flow nasal respiratory therapy (Nasal high flow, NHF) utilises higher gas flow rates than conventional low-flow oxygen systems. The devices used deliver heated and humidified oxygen at a flow of up to 60 litres per minute via nasal cannulas with low level continous positive airway pressure. This study is a prospective randomized study. AECOPD patients with no severe respiratory failure are treated with NHF and conventional oxygen therapy respectively. The target is that NHF can increase the comfort degree of patients,reduce the rate of endotracheal intubation, and shorten the time of hospitalization.
A number of studies have documented poor sleep quality and troublesome symptoms (breathlessness, cough and sputum production) upon awakening in patients with COPD. However, the investigators know very little about measurements of respiratory mechanics (i.e., lung volumes, respiratory pressures, diaphragm function, etc) during sleep in these patients. The investigators also know little about how modern bronchodilator therapies, or the timing of when they are taken, affect respiratory mechanics during sleep or the severity of early morning respiratory symptoms. COPD is often treated with inhaled bronchodilator medications which are used to open up airways and make it easier for air to get in and out of the lungs. The investigators are studying the effects of a new inhaler that contains two different types of long-acting bronchodilator: formoterol [a long-acting beta2-agonist (LABA)] and aclidinium bromide [a long-acting muscarinic antagonist (LAMA) or anticholinergic]. Initial studies have shown that this combination therapy taken twice daily can improve some lung function measurements and respiratory symptoms in patients with moderate to severe COPD. There are also reports that evening administration of this medication may provide important advantages in patients with dominant nighttime and early morning symptoms. It is thought that sustained bronchodilation and lung deflation during the night may improve respiratory mechanics, diaphragmatic function, pulmonary gas exchange, sleep quality, and reduce severity of morning symptoms. This study will be the first to explore the effects of a nighttime dose of aclidinium/formoterol combination therapy on detailed measurements of respiratory mechanics and early morning symptoms in COPD. This study will also give us a better understanding of the mechanisms of early morning respiratory symptoms and their improvement with bronchodilators.
The overarching goal of the project is to improve the process and experience of surrogate decision-making by family caregivers. Since feeling unprepared to make surrogate decisions is a major contributor to caregiver stress, the primary outcome is caregiver self-efficacy --i.e., caregivers' assessment of how well prepared they feel to serve effectively as a surrogate decision-maker. Through follow-on Renewal funding, we are now also qualitatively examining family caregivers' experience with surrogate decision-making.
Dyspnea is the most reported symptom of patients with advanced Chronic Obstructive Pulmonary Disease (COPD) and is undertreated. Morphine is an effective treatment for dyspnea and is recommended in clinical practice guidelines, but questions concerning benefits and concerns about respiratory adverse effects remain. For example, the effect on health-related quality of life and functional capacity is unknown. In one-third of the patients oral sustained release morphine (morphine SR) doesn't relieve dyspnea and it remains unknown whether severity and descriptors of breathlessness may predict a response to morphine. Finally, cost-effectiveness of morphine SR in this patient group is unknown. Therefore, prescription of morphine to patients with COPD is limited. Objectives of this double blind randomized controlled trial are to study the effect of oral administration of morphine SR on health-related quality of life, respiratory adverse effects, and functional capacity; to explore whether description and severity of breathlessness are related with a clinically relevant response to morphine and to analyse the cost-effectiveness of morphine SR. The study population will consist of 124 clinically stable outpatients with COPD and severe dyspnea despite optimal pharmacological and non-pharmacological treatment.
This study evaluates if dabigatran etexilate is safe for use in patients with Scleroderma and Interstitial Lung Disease. All patients will receive 75mg of dabigatran etexilate twice a day for 6 months.
Chronic pulmonary disease (CLD) is the most common manifestation of HIV/AIDS among children, accounting for more than 50% of HIV-associated mortality. Recently, a novel form of CLD, affecting more than 30% of African HIV-infected older children was described by Ferrand et al in Zimbabwe, high-resolution CT scanning findings showed predominantly small airways disease consistent with constrictive obliterative bronchiolitis (OB). . Azithromycin has anti-inflammatory activity and treatment of CLD with this agent may lead to suppression of generalized immune activation. This specific aims of this project are to: 1. Primary objective: To investigate whether adjuvant treatment with azithromycin results in improvement in lung function in HIV-infected children with chronic lung disease, who are stable on antiretroviral therapy. 2. Secondary objectives: 1. To investigate the intervention effect on mortality, exacerbations of lung disease, quality of life, morbidity. 2. To investigate adverse events related to azithromycin treatment In total, 400 children aged 6-16 years, living with HIV and diagnosed with CLD will be enrolled at Harare Children´s Hospital in Harare (Zimbabwe) and Queen Elizabeth Central Hospital in Blantyre (Malawi). These will receive weekly treatment with azithromycin or placebo during 12 months. Another 100 children (50 per site) living with HIV but with no CLD will be enrolled as a comparison group for laboratory sub-studies. Lung function will be assess using spirometry and the Forced expiratory volume in the first minute (FEV1) will be the primary outcome. The mean change in FEV1 z-score levels will be compared between trial arms after 12 months of initiation of azithromycin treatment.
