Active clinical trials for "Bronchitis, Chronic"

AIM: To identify those mechanisms involved in the systemic and muscular response to exercise treatment, in two different Obstructive Chronic Pulmonary Disease (COPD) phenotypes (emphysema and non-emphysema). The investigators will evaluate the effect of exercise training, on exercise outcomes, peripheral muscle strength measures, dyspnea and quality of life indices, and markers of systemic inflammation and muscle repair. SUBJECTS: The investigators will study 30 COPD patients in GOLD II-IV stages, with symptomatic disease. Patients will be differentiated into 2 different phenotypes: predominant-emphysema and non-predominant emphysema (15 subjects for each group), according to high resolution computed tomography (HRCT) scanning images, and after the specific analysis with the MeVisPulmo software. After patients are typified, they will be included in the 12- wk training programme. MEASURES(pre&post-training):Basic blood analysis, EKG, spirometry, blood gases, pletysmography, gas diffusion, maximal inspiratory and expiratory pressure (MIP,MEP), bioimpedanciometry, 1RM test and isometric strength determination, 6-min walking test (6MWT), maximal and submaximal cycle-ergometry, and dyspnea using the Mahler's Basal and Transitional Dyspnoea Indexes (BDI/TDI) and quality of life (Chronic Respiratory Disease Questionnaire [(CRDQ]) evaluation. Besides, the investigators will measure blood PCR and cytokines levels (IL6, IL8, IL10, IL12, TNF-α, IGF-1, and MIC-A & MIC-B). Muscle biopsies will be made (quadriceps) for detection of TNF-α, TNFR-I, TNFR-II, IGF-1Ea and MGF, IGF-1R, genes bound to biogenesis, markers of cell lesion-stress and myosin heavy chains (MyHC) type I and II, N-CAM/CD56 and Met & Desmin

To determine the feasibility of delivering different community nutritional interventions to chronic obstructive pulmonary disease (COPD) patients at moderate or severe risk of malnutrition following a hospitalisation for an acute exacerbation of COPD.

A multicenter,randomized,single-blind, placebo-controlled,phase 4 clinical trial to evaluate the efficacy and safety of andrographolide sulfonate in patients with acute exacerbation of chronic bronchitis

This is a PI-initiated study taking place only at UCLA, sponsored by Sunovion. The investigators plan to enroll about 20 subjects who are at least 40 years old and have Chronic Obstructive Pulmonary Disease (COPD). The purpose of this study is to compare the effectiveness of Brovana and Serevent in helping relieve COPD symptoms. Specifically, the investigators are looking at how much and for how long the two drugs can open up the small airways in the lungs. This will be done with breathing tests on all subjects, and with high resolution CT scans on subjects who agree to this optional part of the study. Half of subjects will take Brovana (arformoterol tartrate inhalation solution) for 2 weeks and then Serevent (salmeterol xinafoate inhalation powder) for 2 weeks; the other half will take Serevent the first two weeks and Brovana the second two weeks. All subjects will also take Spiriva (tiotropium) and will be provided with albuterol for immediate relief of symptoms. After a Screening Visit to determine eligibility, subjects will be randomly assigned to receive Brovana or Serevent for the first 2 weeks, complete Test Visit 1, then receive the other study drug for 2 weeks, and finally complete Test Visit 2. Visits will include questionnaires, review of health and medications, and breathing tests before and after taking the study drug. Subjects who agree to be in the sub-study will also undergo CT scans before and after taking the study drug at both test visits.

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 purpose of this study is to use oral prulifloxacin to treat patient with Acute Exacerbations of Chronic Bronchitis and compare the effect with Levofloxacin.

One of the main goals of the respiratory physical therapy is to help people who are suffering from accumulating of secretions in their airways and lungs. Chronic Obstructive Pulmonary Disease (COPD) patients are often hospitalized with an Acute Exacerbation of their medical condition. Those patients usually get only the standard medical care during the acute phase and don't get respiratory physical therapy treatment. The study's main aim is to investigate if respiratory physical therapy treatment in addition to standard medical care during the acute phase, can improve the respiratory and medical condition and reduce hospitalization stay. In order to do so we will compare three groups of COPD patients during acute exacerbation; two groups will get one out of two respiratory physical therapy techniques; manually or Intrapulmonary Percussive Ventilator (IPV) in addition to standard medical care and the third group will get standard medical care alone.

This trial aims to evaluate the clinical control rate of sputum by Zhuli Capsule in the treatment of the Phlegm-heat Syndrome （Tan-re Zheng）in the patients with acute exacerbation of chronic obstructive pulmonary disease or chronic bronchitis.

The purpose of this study is to show that one form of mechanical airway clearance techniques, High Frequency Chest Wall Oscillation (HFCWO)using a pneumatic vest, will diminish exacerbations of COPD which will improve respiratory health status.

N-acetylcysteine (NAC) is described as having mucolytic and antioxidant properties. It is widely prescribed for patients with chronic obstructive pulmonary disease (COPD), particularly for those who have accompanying symptoms of chronic cough and sputum production. Randomized, placebo controlled indicate that it is safe and that it may have some clinical benefit when used at relatively low doses. It is postulated that substantially higher doses of NAC will be well-tolerated and will provide better symptom control while also decreasing blood makers of oxidant stress and inflammation.
