Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

COPD is a common, serious disease and is a major burden on patients and the National Health Service. Patients with COPD can develop worsening of their symptoms, known as an exacerbation, which can be severe enough to warrant hospital admission. There are currently no objective measurements available to patients and clinicians to predict exacerbation and monitor recovery. Detection of exacerbation by both patients and physicians is known to correlate poorly with onset of respiratory deterioration. Measurement of neural respiratory drive (NRD), or drive to breathe, using respiratory muscle electromyography (EMG) correlates with changes in patients' symptoms and physician defined deterioration during hospital admissions. This pilot study aims to identify whether daily measurement of NRD at home following admission to hospital with exacerbation of COPD can detect an exacerbation within 30 days of discharge (20% of patients are readmitted within this period). This technique could enable early detection of deterioration at home, facilitating earlier treatment compared to current practice, potentially avoiding hospital readmission. 30 patients admitted to St Thomas' Hospital because of an exacerbation of COPD aged 40-80, with a body mass index <35kg/m2, who can follow English instructions and give informed consent, who are discharged home will be recruited. If patients consent to participate, they will have assessments as inpatients and for 30 days at home following discharge, or until hospital readmission, whichever is sooner. Assessments include vital observations (heart rate, blood pressure, respiratory rate and oxygen saturations), NRD, and a symptom questionnaire. At the baseline assessment, age, height weight, a brief medical history, results of tests already taken by the clinical team (blood tests and chest x-ray) and lung function tests will be recorded. This study will take 12 months. Philips and its Affiliates are providing the NRD measuring equipment.

Poor function of the right side of the heart and rise in pressure of the blood vessels leading to the lungs are two main heart-related factors that are associated with worsening of airway disease. A relatively new method which uses magnetic field to create images of the heart called cardiac magnetic resonance (CMR) imaging shows immense promise in detailed and accurate assessment of the heart in patients with airway diseases. This project aims to assess the heart in patients with asthma and chronic obstructive pulmonary disease (COPD) as well as healthy participants using CMR to help us determine features on CMR that are different is patients with asthma and COPD compared to healthy participants. This may help with early identification of patients who are at risk of episodes of acute worsening of airway disease, called exacerbation, and potentially halt the progression of the heart dysfunction with currently available or new treatments. Study involves one visit at Glenfiled Hospital, Leicester, lasting approximately 4 hours. The visit will include following assessments: clinical history, health status, physical examination, electrocardiogram (ECG), blood tests, lung function testing, echocardiogram and CMR. Part of the study will involve a participant questionnaire in which the participants will rate their CMR experience. The results will potentially change the way CMR is undertaken. A sub-set of the participants will also be invited back to do a one off focus group discussing the CMR experience further.

Since the infectious aetiology of AECOPD has been suggested to vary according to geographical region, the primary purpose of this study (which will be conducted in several countries in Asia Pacific) is to evaluate the occurrence of bacterial and viral pathogens in the sputum of stable COPD patients and at the time of AECOPD. Given the increasing and projected burden of COPD in the Asia Pacific region, this study will also evaluate the frequency, severity and duration of AECOPD, as well as the impact of AECOPD on health-related quality of life (HRQOL), healthcare utilisation and lung function.

Investigation into the associations between sedentary behaviour, physical activity, body composition and cardiometabolic risk in COPD. A single assessment visit with fasting blood tests, body composition and strength measures followed by a week of activity monitor wear to record sitting time and physical activity. Cardiometabolic risk markers include fasting glucose, HBA1c, HOMA and lipids and blood pressure.

This study aimed to reveal the role of inspiratory muscles exercise using Inspiratory Muscle Trainer (IMT), which is a form of weight training. The pre- and post study of this experiment were conducted in chronic obstructive pulmonary disease (COPD) outpatient clinic during the period of September 2017 until April 2018. Patients were recruited by consecutive sampling. Inclusion criteria were stable COPD patient with The Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria A-D, who has never received prior exercise for pulmonary rehabilitation, and willing to participate in the study. The exclusion criteria included any problem with extremities and cardiovascular disease. Patients underwent an interview about their medical history, tested spirometry using CareFusion®, and the inspiratory muscle strength was assessed using Micro RPM CareFusion®. The St George Respiratory Questionnaire (SGRQ) was used to assess the health status and the 6-Minute Walking Test (6MWT) was conducted to assess functional capacity. Subject exercised using inspiratory muscle trainer (Philips Respironic®) for eight weeks.

The trial aims to analyse changes in the microbiome of the lower airways after smoking cessation. Microbiome analyses (upper airway swabs, bronchoalveolar lavage, transbronchial brushing) are conducted in smokers before and 6 weeks after smoking cessation. Never smokers serve as a control group and undergo the same sampling procedures once.

This non-Interventional, descriptive, cross-sectional cohort and multicentre study will be conducted with COPD patients attended at Spanish Primary Care offices.

Purpose: To analyze the effects of Ramadan observance (RO) on pulmonary variables, exercise performance and postural balance in patients with chronic obstructive pulmonary disease (COPD). Methods: Twenty COPD patients (age=72.7 ± 4.1 yr, non-smokers, without cardiac or neuromuscular complications) were evaluated. Tests performed one week before Ramadan (C), and during the second (R-2) and the fourth weeks of Ramadan (R-4) included standard spirometry, a quality of life questionnaire (VQ11), a 6-min walking test (6MWT), measurement of maximal voluntary contraction force of the quadriceps (MVC), Timed Get Up and Go (TUG), Berg Balance Scale (BBS) and Unipedal Stance (UST).
