Filter by:The primary objective of this study is to assess the pharmacokinetics of tiotropium + olodaterol fixed-dose combination (FDC) (5 μg/ 5 μg) delivered by the RESPIMAT inhaler after single dose and at steady state in Chinese patients with COPD. The secondary objective is to assess the safety of tiotropium + olodaterol FDC (5 μg/ 5 μg) delivered by the RESPIMAT inhaler after 3 weeks once daily treatment in Chinese patients with COPD.
An open-label, single dose Pharmacokinetic (PK) comparability study to demonstrate comparable drug exposure following Subcutaneous benralizumab administration by using accessorized pre-filled syringe (APFS) or autoinjector (AI) devices.
AZD7594 is a non steroidal, potent and selective modulator of the glucocorticoid receptor (GR) under development for once daily inhaled treatment of chronic obstructive pulmonary disease (COPD) and asthma. Abediterol is a novel and selective β2 adrenergic receptor agonist with the potential for once daily treatment of asthma and COPD in fixed dose combination (FDC) with an ICS or a novel anti inflammatory (AI) agent. This study will be the first clinical study for the combination exposure of AZD7594 with abediterol as 2 compounds in FDC or in free combination via 2 separate dry powder inhalers (DPIs). This study will be conducted in healthy male subjects to minimize the effects of concomitant disease states or medications on study measurements.
Epidemiological investigations has suggested exposure to air pollution linked with respiratory disease, especially chronic obstructive pulmonary disease. However, the potential mechanisms of adverse effects remains scare. The present study will assess the association between air pollutants and respiratory related parameters to elucidate possible mechanisms.
Chronic obstructive pulmonary disease (COPD) patients often undergo thoracic surgery due to lung cancer and emphysematous changes. One lung ventilation (OLV) used in thoracic surgery aggravates hypoxia and hypercapnia increasing intrapulmonary shunt and dead space.Ketamine provide bronchodilation by inhibiting the reuptake of catecholamines in the circulation. It also serves relaxation of bronchial smooth muscle. Our aim in this study, effects of ketamine on arterial oxygenation, the shunt fraction and the lung mechanics in patients with COPD who administered OLV because of thoracic surgery. Thirty patients with COPD who undergo thoracotomy for lung lobectomy will be included in this study. Patients will be randomly divided to a control group (%0,9 saline- CG) or a keta (ketamine- KG) group. KG will be administered 1 mg/kg ketamine bolus, then 0,5 mg/kg/hour ketamine infusion after the induction, CG will be administered sline bolus, then saline infusion. Peak airway pressure (Ppeak), plato airway pressure (Pplato), static compliance, shunt fraction, PaO2/FiO2 and arteriel blood gas values (Pa02, PaC02) will be recorded before initiation of OLV and 30 minutes intervals after initiation of OLV.To evaluate the postoperative pulmonary complications, Pa02, PaC02 in blood gas and Pa02/Fi02 values will be recorded 20 minute after arrival at postoperative care unit. Patients will be evaluated for pneumonia, atelectasis and acute lung injury at postoperative 72 h and findings will be recorded. 30 day mortality will be recorded.
Breathing movements, called chest wall motion, are very complex. The investigators are studying how movement of the abdomen, ribs and diaphragm contribute to breathing and how this differs with different diseases in the chest. Breathing movements may help with diagnosis, assessment of severity or assessing the impact of treatments for chest conditions. The investigators are following people who have a chest disease, measuring their chest wall motion and comparing it to their diagnosis and and how their treatment works. Chest wall motion can be measured in different ways at rest and whilst exercising. Small stickers on the chest can be used to reflect infra red light or visible squares of light can be shone onto the chest without using stickers.
The investigators will conduct a randomized, controlled, double-blind, crossover trial to determine whether the presence of a portable high-efficiency indoor air filter in the bedroom reduces respiratory symptoms in former smokers compared with placebo. The primary outcomes will be change in St. George's Respiratory Questionnaire - COPD (SGRQ-C) score associated with using a portable high-efficiency indoor air filter during the study period. Secondary outcomes of COPD exacerbations and hospitalizations, daily step counts, medication changes, spirometry, and cardiovascular outcomes will also be assessed.
The study assessed the safety and ability of several doses of an orally inhaled medicine [ie, Glycopyrrolate Inhalation Solution = GIS] to improve airflow in the lungs when delivered with an electronic eFlow nebulizer system in patients with Chronic Obstructive Pulmonary Disease (COPD). The study was conducted in 12 patients in 2 parts. Part 1 was designed to find the once-a- day GIS dose that produced the highest improvement in lung airflow. Part 2 tested the GIS dose with the highest improvement in lung airflow and a placebo (ie, no drug) delivered by a general purpose nebulizer. The airflow improvements of the same GIS dose were compared between the two nebulizer systems to determine what effect the device had on GIS delivery.
The study assessed the safety and ability of an orally inhaled medicine [i.e., Glycopyrrolate Inhalation Solution = GIS] to improve airflow in the lungs when delivered using an eFlow nebulizer in 42 patients with Chronic Obstructive Pulmonary Disease (COPD). Each patient randomly received several, single doses of GIS, or placebo, separated by approximately 1 to 2 weeks. After the dose was given, lung airflow was measured over 24 hours and blood was collected to measure how much GIS was in the bloodstream. The study was conducted to find the once-a- day GIS dose that produced the highest improvement in lung airflow using the eFlow nebulizer.
This is a prospective study of patients diagnosed with chronic obstructive pulmonary disease (COPD) with respiratory failure and admitted in West China Hospital during April 2017 to March 2019. The following variables will be prospectively studied: age, sex, height, weight, respiratory function indicators, arterial blood gas analysis results, biochemical data, nutritional risk screening 2002 (NRS 2002) score, short-term and long-term prognostic outcomes. The purpose of this study is to assess whether NRS 2002 is a useful prognosis predictor in COPD patients with respiratory failure.
