Filter by:Chronic obstructive pulmonary disease (COPD) is a condition defined as a disease state characterized by airflow limitation that is not fully reversible. The airflow limitation is usually progressive and is associated with an abnormal inflammatory response of lungs to noxious particles or gases, primarily caused by cigarette smoking. The accelerated decline in lung function is closely associated with an increased number of neutrophils in the sputum and hence with higher level of airway inflammation. It becomes clear that the inflammatory process potentiates as COPD progresses and exerts damage which is irreversible. Oxidative stress is inextricably linked to the inflammatory response. There is increasing evidence that an oxidant/antioxidant imbalance, in favor of oxidants, occurs in COPD. NAC has been reported to reduce the viscosity of sputum in both cystic fibrosis and COPD, facilitating the removal of pulmonary secretions. Moreover, by maintaining the airway clearance, it prevents bacterial stimulation of mucin production and hence mucus hypersecretion. The superiority of NAC over the other mucolytics may be in its anti-inflammatory and antioxidant properties and its mucolytic actions. The aim of this study is to evaluate the effects of treatment with NAC long on oxidative stress marker change and also explore the effect of NAC to airway inflammatory, lung function test and CAT scores. Selected oxidative stress marker was defined as 8 - isoprostane, protein carbonyl, DNA damage.
This will be a randomized, cross-over trial evaluating the efficacy of nasal high-flow oxygen therapy (HFOT) vs. low-flow oxygen therapy (LFOT) on cycling endurance in patients with chronic obstructive pulmonary disease (COPD).
Open-label comparative multicentric cohort study in COPD patients with LABA/ICS, switched to either tiotropium/olodaterol and observed for 12 weeks approximately.
Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory disease of the airways and lungs that develops against harmful particles or gases with exacerbations. Coexistence of bronchiectasis with COPD may lead to worsening of the functional parameters as well as alteration of the microbiological pattern in exacerbations and may negatively affect the exacerbation result parameters.
Study is conducted to assess the prevalence and structure of comorbidity among patients undergoing abdominal surgery and produce the stratification of the risk of postoperative complications by identifying independent predictors for its development.
Introduction: Chronic obstructive pulmonary disease (COPD) is characterized by airflow obstruction, which is clinically manifested by dyspnea and leads the patient to a vicious cycle of sedentary lifestyle. Pulmonary rehabilitation (PR) is an important therapeutic strategy to break this cycle. Cardiovascular diseases are frequent in patients with (COPD) and are associated with higher mortality. The effects of (PR) on cardiovascular risk factors in patients with (COPD) have been little studied so far. Objectives: To evaluate the effects of pulmonary rehabilitation compared to the control group on cardiovascular risk factors in patients with (COPD). Methods: A randomized clinical trial will be conducted. Patients with (COPD) will be divided into two groups: Group I (GI): group that will be rehabilitated, with 3 weekly sessions, for 8 weeks and Group II (GII): control group, without intervention. In both groups, a baseline evaluation will be performed, which will be repeated after 9 weeks and consists of: clinical and laboratory parameters, endothelial function (FMD) and brachial ankle index (ABI). Outcomes commonly used in the assistance to assess (PR) will also be measured. Expected Results: The study is expected to improve understanding of the impact of (PR) on cardiovascular variables in patients with (COPD).
Validate a simple clinical tool to evaluate physical activity (the question "How many minutes does it walk per day?" Or equivalent), compared to the rest of the collected physical activity data (PROactive questionnaire and objective physical activity data by means of an accelerometer record) in patients with COPD.
To compare the effects of high flow nasal oxygen with usual care during an outpatient 6-week pulmonary rehabilitation program after hospitalization for COPD exacerbation.
In COPD patients with chronic hypercapnic respiratory failure, the prognosis is poor and the treatment with non invasive ventilation is actually well established. However the best mode of ventilation is not well known. In severe COPD patients various disorders of respiratory mechanics result in insufficient ventilation, which can be life-threatening or create NIV discomfort. The main characteristic of these disorders is a cyclical closing of small airways that can limit an expiratory flow and provoked some fluctuations in flow curve. To our knowledge, the management of dynamic hyperinflation seems to play an important role in explaining the effect of the NIV. Few studies have examined the effects of the machine's adjustments on dynamic hyperinflation. The main objective of this study is to analyze the impact of specific ventilatory modes supposed to reduce the dynamic hyperinflation on the hematosis, by studying transcutaneous pressure of carbon dioxide, in severe hypercapnic COPD patients ventilated by NIV. Two modes of ventilation will be compared. First one is an algorithmic mode developed by the company Löwenstein (AirTrap Control, Trigger Lockout and the Expiratory Pressure Ramp). The second one is a standard algorithmic mode, used in the same ventilator. These two ventilatory modes will be evaluated in each patient, during two consecutive nights in current living conditions at home.
Primary Objective: To evaluate the efficacy of dupilumab administered every 2 weeks in patients with moderate-or severe Chronic Obstructive Pulmonary Disease (COPD) as measured by - Annualized rate of acute moderate and severe COPD exacerbation (AECOPD) Secondary Objectives: To evaluate the effect of dupilumab administered every 2 weeks on - Pre-bronchodilator forced expiratory volume in 1 second (FEV1) over 12 weeks compared to placebo - Health related quality of life, assessed by the change from baseline to Week 52 in the St. George's Respiratory Questionnaire (SGRQ) - Pre-bronchodilator FEV1 over 52 weeks compared to placebo - Lung function assessments - Moderate and severe COPD exacerbations - To evaluate safety and tolerability - To evaluate dupilumab systemic exposure and incidence of anti-drug antibodies (ADA)
