Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

The first-in-man study are designed as below to assess safety, tolerability, and preliminary pharmacokinetics of ZL-2102. Double-blind randomized, placebo-controlled ascending single oral doses (Part 1, ZL-2102-SAD); Open-label, randomized, 2-sequence, 2-period, 2-treatment crossover (Part 2, ZL-2102-FED); Double-blind randomized, placebo-controlled, ascending repeated oral doses for 14 days (Part 3, ZL-2102-MAD). A total of 104 subjects will be enrolled.

Main adverse events of Roflumilast are weight loss, loss of appetite, insomnia, headache, diarrhea, vomiting, and nausea. Although the majority of these adverse reactions were mild or moderate. They occurred mainly at the beginning of therapy and mostly resolved with continued treatment around for two weeks according to experiences of clinicians. These adverse events occur more often in Roflumilast 500 μg than 250 μg, having negative impact on compliance of patients at the early stage of treatments. Thus, investigators aim to compare the drop-out rates between the usual dosage (Roflumilast 500 μg once daily) and the dose escalation (Roflumilast 250 μg once daily for 4 weeks and then escalating dose of 500 μg once daily).

People with chronic obstructive pulmonary disease (COPD) are very sedentary and efforts to establish an active lifestyle are challenging because of periodic acute exacerbations of COPD that interrupt physical activity patterns and contribute to further decline in physical activity. The purpose of this preliminary research is to learn more about the experience of acute exacerbations of COPD (AECOPD) from the perspective of the patient and his/her family and to learn how AECOPDs affect physical activity.

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.

Mechanical devices to increase the individual's bronchial hygiene are commonly used to assist patients with chronic retention of secretions. VAKÜM technology has been recently developed with the aim to improve the respiratory condition in hypersecretive patients suffering from chronic respiratory diseases. The aim of this study is to assess the clinical efficacy of VAKÜM technology in patients with hypersecretion, and chronic respiratory diseases a clinical trial has been designed. Patients with chronic respiratory diseases, hypersecretion (sputum production >30 mL/die), and reduced cough efficiency (Peak Cough Expiratory Flow > 150 and < 300 L*min-1) referred to standard pulmonary rehabilitation (PR) will be included. Study design is a single-blind multicentre randomized trial with consecutive recruitment. Following a preliminary run-in period, group comparison will be made between Intervention group using VAKÜM system (Free Aspire, MPR, Legnano-I) added to the conventional manual ELTGOL technique, and Control group using manual ELTGOL alone over 10 daily sessions. Spirometric lung volumes, respiratory muscle strength, arterial blood gases, and quality of life will be recorded in both groups pre-to-post PR. Perceived dyspnea (by VAS scale), sputum volume and characteristics (on a semi-quantitative 3-point scale) and peak expiratory air flows (PEF and PCEF) will be registered on a daily basis over the study period. Primary outcome is the change in perceived dyspnea; in order to ensure 80% power to detect a 5 point (SD 5) group difference change in the primary outcome at the end of the study period as significant at the 0.05 level, at least 42 patients per group are needed. The minimum target sample size will be then fixed at 50 patients per group. An higher and faster significant reduction of the perceived dyspnea is supposed in the Intervention group. Additional benefits among the secondary outcomes are also hypothesised in the same group.

The investigators are studying the effect of a single dose Opioid drug (Morphine) on dyspnea and exercise tolerance in COPD patients.

Chronic obstructive pulmonary disease (COPD) is characterized by the obstruction is not fully reversible airway, where the severity of the disease and the prognosis is not determined solely by changes in lung function. Pulmonary rehabilitation is a multidisciplinary program of care for patients with chronic respiratory diseases, individually designed to optimize physical and social performance and autonomy of these patients, promoting improvement in functional exercise capacity, quality of life, reducing dyspnea, frequency and duration of hospitalizations and reduce the frequency of exacerbations of the disease. The overall objective of the research is to evaluate the effects of pulmonary rehabilitation program on exercise capacity, lung function, quality of daily life and reduction of dyspnea in patients with COPD. A study type randomized, open-label trial following the recommendations of the CONSORT (Consolidated Standards of Reporting Trials) will be held. The study will be conducted at the Clinic Physiotherapy Course of the School with a sample of 58 patients. The intervention will be performed sessions three times a week for 16 weeks (8 weeks for assessment and 8 weeks for adaptation and (pulmonary rehabilitation training). The PR (pulmonary rehabilitation) will last 60-120 minutes each.O group A (control) will receive treatment of traditional pulmonary rehabilitation and without resistive training for upper limb (UL) and group B will receive the same treatment control with additional training of upper limb strength.

Objective: To estimate the effectiveness of muscle training, the degree of dyspnea and aerobic capacity in patients over 50 with COPD, in a health care institution provider in Antioquia. Question: What is the effectiveness of muscle training, in the degree of dyspnea and aerobic capacity in COPD patients over 50 years, in a health service institution provider in the department of Antioquia? Hypothesis: Muscle training causes changes in the degree of dyspnea and aerobic capacity, other than the breathing exercises and relaxation Design: Randomized clinical trial with allocation and blinding of the autcomes assesor. Participants: COPD patients stage II and II, male and female, over 50 years old, who are attending to a community health service provider in the department of Antioquia. Intervention: A physiotherapeutic intervention using PNF technique was applied to the experimental physiotherapy group versus Yoga sessions applied to the other group. Twelve weeks protocol performing three sessions per week. Outcome measures: Dyspnea degree and aerobic capacity was measured using the MMRC scale and the six minute walking test respectively at the begining and the end of the study.

Several impairing factors contribute to physical limitation in chronic obstructive pulmonary disease (COPD) as deconditioning, muscle dysfunction and physical inactivity. The available literature clearly indicates that these therapeutic targets benefit from exercise training in patients with COPD and, currently, the key point is not whether patients should or not exercise, but which is the specific contribution of each exercise modality to this population. About this topic, the characteristics of a physical training program to be offered to patients have been a point discussed among researchers in this field, although recently the high-intensity training has been recognized as superior in comparison to the low-intensity training. Literature also indicates that, in order to change the sedentary lifestyle of patients with COPD, long-term training programs are indicated. However, a doubt still remains: if long-term programs are one of the key points to reduce physical inactivity, it is not yet clear whether it is necessary to include high-intensity exercises in that long-term program. If the duration is the only factor influencing the outcomes of the program, thus the intensity of training could be reduced, increasing the adherence of patients to the protocol. Based on this hypothesis, the aim of this study is to compare the effects of two physical training protocols in a long-term rehabilitation program (6 months) in patients with COPD: a high-intensity protocol (based on endurance and resistive training) and a low-intensity protocol (based on callisthenic and breathing exercises training). It is expected that the results of this study contribute to the scientific literature by demonstrating whether low- and high-intensity training contribute equally to change the sedentary lifestyle of patients after a long-term exercise program.

The aim of this clinical trial is to evaluate the effect of chronic obstructive pulmonary disease (COPD) and/or obstructive sleep apnea syndrome (OSAS) on the endothelial function, before cardiovascular surgery, compared to non COPD non OSAS patients undergoing also a cardiovascular surgery, by an observational physiological study. An interim analysis will be performed when 100 patients will be included.
