Filter by:The aim of this postmarketing surveillance is to obtain further information about the tolerability and efficacy of Berodual® metered-dose inhaler in the treatment of chronic obstructive respiratory tract disease under conditions of daily practice
Tolerability, efficacy and handling of Berodual® Respimat® 20/50µg/dose solution for inhalation in patients with chronic obstructive airways disease in daily practice
Tolerability, efficacy and handling of Berodual® Respimat® 20/50µg/dose solution for inhalation in patients with chronic obstructive airways disease in daily practice
The purpose of this study is to compare the systemic exposure to BI 1744 BS and tiotropium at steady state following inhalation of the fixed dose combination (FDC) of 10 μg BI 1744 CL plus 5 μg tiotropium bromide with the systemic exposure to BI 1744 BS and tiotropium at steady state following inhalation of the single agents, i.e., 10 μg BI 1744 CL and 5 μg tiotropium bromide, when administered once-daily via the Respimat® Inhaler for 21 days. The secondary objectives were to compare the safety and tolerability (adverse events, 12-lead electrocardiogram recordings, pulmonary function testing) of BI 1744 CL and tiotropium bromide when administered as fixed dose combination or as single-agent therapy.
Lung transplantation is a well established method for surgical therapy for patients with end stage pulmonary disease. The investigators seek to determine to which extent the pulmonary vascular barrier gets harmed during lung transplantation and whether pulmonary edema after reperfusion can be monitored with measurement of extravascular lung water index (ELWI). Additionally the investigaors are going to evaluate the correlation between ELWI and shedding of the endothelial glycocalyx. The study is designed as a prospective observational cohort study.
Chronic Obstructive Pulmonary Disease (COPD) is the most common pulmonary disease, responsible for considerable morbidity and mortality and is the third leading cause of death worldwide. As well as its consequences in the lungs, COPD is well recognized to be associated with a range of important systemic consequences and co-morbidities. Interestingly, skeletal muscle dysfunction is noted in both early and advanced disease, suggesting its origins may not be wholly pulmonary. Treatment strategies targeting lung function are, unfortunately, of limited value. Given the burden of disease, it is becoming increasingly important that investigative and therapeutic work now focuses on other systemic characteristics and sequelae which define the disease phenotype. This is a randomized controlled trial of the effect of 14 days of voluntary reduced activity on muscle mass, muscle strength, body composition, and atrophy signalling in patients with COPD and age-matched controls. The primary hypothesis upon which this study is based is that a short reduction in ambulation will induce a transient reduction in quadriceps muscle mass, quadriceps strength and physical performance in patients with COPD compared to matched COPD patients whose mobility has not been restricted. The secondary hypothesis is that the magnitude of the above changes will be greater in physically inactive COPD patients compared to physically inactive age-matched controls. The overall aim of this research is to use an in vivo human model of 14 days of voluntary reduced physical activity to test the above hypotheses. If the model proves feasible, this will allow for earlier proof of concept studies of novel therapeutic agents.
The objective of this study is to investigate molecular, cytological and genetic features of occupational chronic obstructive pulmonary disease (COPD) in conditions of different occupational exposures. In order to achieve this goal serum pro-inflammatory cytokines and standard inflammation markers level, hemostasis, cytological analysis of bronchoalveolar lavage and associations of single nucleotide polymorphisms (SNPs) rs1800470 transforming growing factor β1 (TGF β1) gene, rs1828591 hedgehog interacting protein (HHIP) gene, rs4129267 interleukin 6 receptor (IL-6R) gene, rs1051730 nicotinic acetylcholine receptor 3 (CHRNA3) gene with COPD in subjects exposed to silica dust and in those exposed to polycyclic aromatic hydrocarbons exhaust will be investigated. The relationship between genotype and phenotype characteristics, such as an inflammation activity, assessed by C-reactive protein (hsCRP) and tumor necrosis factor-α (TNF α) serum concentration, in different occupational COPD groups will be studied. The hypothesis is that the mechanisms underlying disease development and progression are different due to environmental risk factor that reflex in differs in disease attributes - molecular biomarkers, cytology results and genetic susceptibility between COPD due to dust, COPD due to chemicals and COPD in smokers therefore COPD can be subdivided into ecological phenotypes according to environmental risk factor.
Electronic noses detecting patterns of volatile molecules have recently been introduced for different diagnostic purposes. The diagnostic accuracy of a prototype e-nose device (Bruins et al (2013) in Bangladesh showed sensitivity of 76.5-95.9% and specificity of 85.3-98.5%. Here the investigators test a production type point-of-care hand-held device with less detectors. The investigators explore factors such as food intake, smoking, and co-morbidity, as well as the impact of TB treatment, and address the question whether the device could help monitor disease and response to treatment.
Chronic obstructive pulmonary disease has become a serious global health care and public health problems due to its high prevalence, high morbidity and heavy economic burden. Acute exacerbation of chronic obstructive pulmonary disease is one of the most important causes of death in patients with COPD. Systemic corticosteroids therapy is recommended in COPD exacerbations. In clinical practice for the treatment of acute exacerbation of COPD， antibiotic application is still controversial. Evidence from current guideline is based on strict criteria from randomized controlled trials, thus the given condition is simplified. Patients meet the criteria account for the minority in the real world. Therefore, it is still not clear whether most patients benefit from the recommended treatment. In our design, hospitalized patients with acute exacerbation of COPD will be enrolled, with their treatment, arterial hypoxemia, recovery time and length of hospitalization being observed. The main purpose is to evaluate the benefit effect of current recommended treatment of acute exacerbation of COPD in the real world.
Pulmonary Rehabilitation became a vital part of management in COPD patients in form of activity modification, dietary and pharmacological optimisation. But access to traditional supervised aerobic (treadmill) walking is debatable fact due to economical and staffing expertise in developing countries like India. The investigators designed a randomised controlled trial to evaluate the effectiveness of ground based walking over traditional treadmill walking in improving quality of life in COPD patients.
