Filter by:Given the importance of the correct use of inhalers by patients with Chronic Obstructive Pulmonary Disease (COPD) for the appropriate treatment of the disease, the self-care programme which will be assessed will consist of an educational intervention on the correct use of inhalers. For this aim, we have designed this study to assess the influence of both individualized and collective self care programmes about the correct use of inhalers improves the functional state of patients with COPD compared to when there is no educational intervention.
Beta-endorphins, which are naturally occurring narcotic substances, have been shown to alter the perception of breathlessness. Oral ketoconazole, an antifungal antibiotic, increases blood levels of beta-endorphins. The study hypothesis is that oral ketoconazole will reduce ratings of breathlessness induced by resistive breathing loads.
Asthma and chronic obstructive pulmonary disease(COPD) are common diseases, which tend to even increase in many countries. Both from a clinical and a pathophysiological point of view, this is an important issue. However, an understanding of the relationship between the complex array of cells and mediators involved in asthma and COPD is not yet fully dissected which makes difficult to find a specific and sensitive panel of biomarkers that can reflect intensity of these pathological processes and can help to predict the individual outcome.
This study involves the development and evaluation of a web-based, interactive education program on chronic obstructive pulmonary disease (COPD) for primary care clinicians. The research questions that this proposal addresses include: 1. Can an interactive, web-based COPD course be developed to disseminate evidence-based, best practice recommendations to primary care clinicians? 2. Can assessment tools be developed to evaluate the impact of the program on clinician behavior in clinical practice and on patient care?
Respiratory virus infections are a common cause of COPD exacerbations and antiviral therapies have potential as treatments for exacerbations. However it is likely that treating patients when they present with an exacerbation with antiviral drugs will be too late to be effective and earlier treatment at the time of the initial upper respiratory tract infection (URTI) will be required. The incidence of exacerbations following URTIs in COPD patients, and whether there are host factors and biomarkers that can identify the risk of this, is unknown. The aims of this study are to establish the proportion of viral URTIs that progress to an acute exacerbation in COPD patients and identify clinical, viral and biological markers that predict risk of an exacerbation following an URTI. In addition we will determine the frequency of, and risk factors for, bacterial infection following viral URTIs in COPD patients. This data will permit development of a model combining baseline patient characteristics, clinical measurements and biomarkers to predict exacerbation risk following viral URTI in COPD patients. The results will open the way for trials of antiviral therapy in COPD exacerbations and targeting of treatment to high risk patients.
The objective of this study is to evaluate the safety and tolerability of GSK573719/GW642444 Inhalation Powder 125/25 mcg once-daily. The product will be delivered via the Novel Dry Powder Inhaler (nDPI) over 52 weeks to Japanese subjects with Chronic Obstructive Pulmonary Disease (COPD). This is a multi-centre, open-label study evaluating the safety of GSK573719/GW642444 Inhalation Powder 125/25 mcg. Treatment will be given once-daily in the morning. The target enrolment is approximately 120 subjects at approximately 20 study centres in Japan. The total duration of subject participation will be 54-55 weeks, consisting of a 7-14 day run-in period, 52-week treatment period and 1-week follow-up period. Subjects meeting all of the inclusion criteria and none of the exclusion criteria at screening visit (Visit 1) will enter 7-14 day run-in period. The run-in period is provided for completion of baseline safety evaluations and to obtain baseline measures of COPD status. At Visit 2, eligible subjects will start to take GSK573719/GW642444 125/25 mcg, and enter the treatment period. This treatment will be delivered via the Novel Dry Powder Inhaler (nDPI) once daily in the morning for 52 weeks. One nDPI will contain 30 doses of study medication. Subjects will be instructed to administer medication once daily in the morning for the duration of the 52-week treatment period. Each subject should be advised to adhere to this dosing regimen throughout the study. There will be a total of 8 study visits including at screening (Visit 1), initiation of treatment (Visit 2), and at 4weeks, 8 weeks, 12 weeks, 24 weeks, 36 weeks, 52 weeks (Visit 3 through Visit 8, respectively). Follow-up (Visit 9) will be conducted by the phone contact approximately 1 week following the completion/withdrawal of treatment period. A subject will be considered to have completed the study upon completion of the last on-treatment visit (Visit 8). At the end of the treatment period, subjects will be prescribed appropriate COPD medication at the investigator's discretion.
Pilot study in 10 stable male subjects with severe-to-very severe Chronic Obstructive Pulmonary Disease (COPD) to evaluate the effects of short term use of the Breathe Technologies ventilation system on respiratory mechanics during constant work rate exercise in subjects with severe COPD. Two healthy male control subjects will also be evaluated in orde to validate the data collection system.
The purpose of this study is to further characterize the dose response of GSK573719 at doses of 15.6 micrograms (mcg) to 125 mcg once daily in patients with chronic obstructive pulmonary disease (COPD). Treatment with doses of GSK573719 dosed twice daily will also be included to further evaluate dosing frequency. Treatment with tiotropium (18 mcg) once daily via the Handihaler will be included as an active control. A placebo treatment will be included in order to evaluate absolute treatment effect of the different doses of GSK573719.
Noninvasive ventilation (NIV) is a form of ventilation delivered by a mask and is an important mode of treatment in patients with both acute and chronic respiratory (breathing) failure. Humidification is widely accepted as an essential part of the ventilation strategy in patients receiving invasive ventilation (i.e. via a tube inserted into the mouth), but its role during NIV use is not proven. Consequently, there is a variation in practice with regard to humidification during NIV. Humidification is important in maintaining upper and lower airway mucosal function and patients requiring NIV often report symptoms, such as throat dryness, due to a lack of airway humidity. Success of NIV in the acute setting is dependent on many factors including, patient tolerance of NIV during the acute phase. In patients with chronic obstructive airways disease (COPD), poor tolerance results in NIV failure, which necessitates endotracheal intubation or treatment failure. Furthermore, invasive ventilation increases the risk of a hospital acquired pneumonia, which is associated with a worse outcome. In the long term setting of NIV use, again patients frequently report symptoms due to drying of the airways and adherence to NIV can be highly variable. Adherence in these patients is important in improving both quality and length of life. Humidification devices may be technically effective, but clinicians have concerns regarding potential negative effects of these devices. There is a requirement to evaluate the use of humidification in both the acute and long term use of NIV, particular, in terms of patient ventilator interaction, which will impact on comfort and adherence to NIV. This will effect the overall effectiveness of ventilation. The investigators propose a randomised controlled trial to investigate the effects of a humidification system during noninvasive ventilation.
To evaluate a novel advanced physiological monitoring system to improve nocturnal non-invasive ventilation (NIV) in Neuromuscular disease (NMD), Chest wall disease (CWD), Chronic Obstructive Pulmonary Disease (COPD) and Obesity Hypoventilation Syndrome (OHS) patients. By enhancing sleep comfort, adherence to ventilation will increase which, in turn, will improve ventilatory failure, quality of life and reduce length of admission during initiation of therapy. We aim to incorporate this technology into routine clinical practice.
