Active clinical trials for "Bronchitis, Chronic"

Heated, humidified high-flow air (HHHFA) devices improve airway clearance. HHHFA use for an average of 1.6 hours a day in COPD patients with chronic bronchitis improves health-related quality of life, lung function, and delays the first respiratory exacerbation. However, HHHFA for an average of 1.6 hours a day had no effect on COPD exacerbation frequency or hospitalization, dyspnea, or exercise capacity, likely due to short duration of the treatment. Conversely, the effect of HHHFA for longer time periods on chronic bronchitis patients has not been studied. Moreover, the effect of HHHFA on sleep quality has not been studied. A prior study in COPD patients showed that use of HHHFA for more than 7 hours during sleep can be achieved. The overall objective of this research is to examine the effect of HHHFA during sleep on COPD patients with chronic bronchitis. In this pilot study, the study team will examine the effect of HHHFA during sleep on clinically relevant short-term outcomes including: respiratory symptoms, quality of life and sleep, lung function and exercise capacity. Subjects will be recruited and consented. Once a subject agrees to be in the study the baseline visit will occur. The first test will be the Pulmonary Function testing. If the subject qualifies based on the PFT's they will complete the remainder of the baseline visit. During this visit subjects will complete questionnaires, have a physical, 6 minute walk test and CT scan. Subjects will receive device training on the heated, humidified high-flow air device. Subjects will have a followup call between 3-7 days to check in on how the subject is doing with the device. After 6 weeks the subject will return for another round of testing as was done at baseline. This will be the final study visit.

The purpose of this study is to evaluate the efficacy and the safety of two doses of CHF6001 (Tanimilast) as add-on to maintenance triple therapy in the target patient population.

Comparison of Blow Bottle Positive Expiratory pressure(BBPEP) versus Acapella on Oxygenation ,peak Expiratory Flow Rate(PEFR)among patient with chronic bronchitis.

This is an open-label, multicenter, single-group study designed to determine the effectiveness of Mucinex® when used by patients to treat SCB over a 12-week period, following a 2-week run-in period of no treatment (to establish a baseline).

This Phase IIa, multicenter, randomized, double-blind, placebo-controlled, crossover study will evaluate the efficacy, safety, pharmacokinetics, and pharmacodynamic (PD) effects of GDC-6599 compared with placebo in patients with a history of chronic cough.

Chronic Obstructive Pulmonary Disease (COPD) is defined as an impaired ability to move air within the lungs and is a major public health problem that is projected to rank fifth worldwide in terms of disease burden and third in terms of mortality. Chronic bronchitis (CB) is a common clinical phenotype within the umbrella of a COPD diagnosis and is classically defined as chronic cough and sputum production for 3 months a year for 2 consecutive years2, but many studies have used different definitions to define it- chronic cough and sputum production for one year or cough and sputum production on most days of the week. CB is associated with multiple clinical consequences, including; the worsening of lung function decline, increasing risk of acute exacerbations of COPD, increased risk of developing pneumonia, reduced health related quality of life, and an increase in all-cause mortality.

To preliminarily evaluate the safety and feasibility of the pulsed electric field ablation system independently developed by Zhouling (Shanghai) Medical Appliance Co., Ltd. in the treatment of chronic bronchitis.

The purpose of the study is to evaluate the efficacy and safety of two doses of CHF6001 (Tanimilast), as add-on to maintenance triple therapy in the target patient population.

Post-market clinical study (registry study) to collect post-market safety and clinical utility data in European patients with chronic bronchitis treated with RheOx.

It will be a randomized control trial study in which data are collected from hospital. A sample of 26 patients will divided into two group. One group of 13 patients will receive early mobilization and other group of 13 patients will receive early mobilization and chest physiotherapy only. All subject will receive 30 minute two session per day till two weeks. Outcome will be measured with MRC dyspnea scale and Pulmonary function test with spirometry to measure FEV1 and FEV1/FVC and quality of life will be checked by using ST. GEORGE'S respiratory questionnaire. Data will be analyzed by using SPSS version 21.
