Active clinical trials for "Lung Diseases"

PUMA is an observational, multicentre, multinational, cross-sectional study with primary care physicians (primary care, general and family physicians). Participants will be selected sequentially among patients at risk for Chronic Obstructive Pulmonary Disease (COPD) who attend primary care consultation (primary care, general and family physicians). The inclusion visit will be a regularly scheduled or spontaneous consultation for patients, and this appointment with the physician will not depend on the study. During the appointment, data will be collected from the patient and the physician.

The SimplyGo Study is a single site, cross-over study which aims to enroll a maximum of 30 participants (to allow for 20 completed data sets) with a prescription for nocturnal oxygen, and meeting all eligibility criteria.

The aim of this study is to investigate the development of partial pressure of carbon dioxide during the 6-min walking test and during night in Chronic Obstructive Pulmonary Disease (COPD)-patients (GOLD stage IV). Therefore the partial pressure of carbon dioxide, oxygen saturation and the heart rate are registered by a device called "Sentec" during the mentioned periods. In addition a measurement of activity is realised by an activity monitor ("Sensewear").

Chronic Obstructive Pulmonary Disease (COPD) is a major health concern, with a substantial impact on a patient's life. However, the impact of COPD is currently under-recognised and, as a result, COPD is under-treated. An exacerbation of COPD is a major element that causes poor quality of life and loss of productivity. Therefore, minimizing the frequency of exacerbations is a short term treatment goal in COPD management and could improve Quality of Life (QoL) significantly in all severity groups of COPD. Although the use of spirometry for the determination of disease severity in COPD is supported by guidelines, a lung function test alone does not provide a measurement of the overall impact of COPD on health status and is not generally available especially in primary care centre. Therefore, a standardised and effective dialogue between patients and physicians in a consultation could address the impact of COPD on a patient's QoL in this situation. The COPD Assessment Test (CAT), recently launched in 2009, is a short and simple, self-administered questionnaire designed to assess the condition of patients and overall impact of COPD, and to improve patient-physician communication. It has been proven that the CAT has good repeatability and discriminative properties which suggest that it is sensitive to treatment effects at a group level. The CAT score with its better ability to assess the impact of COPD on patients, suggests potential to predict a significant change in COPD status such as acute exacerbations of COPD. Since the CAT is designed to assess the impact of COPD on the patient by measuring overall impairment, it has better correlations with other instruments, such as the Clinical COPD Questionnaire (CCQ), MRC (Medical Research Council) dyspnoea scale, St George's Respiratory Questionnaire (SGRQ),and the 6-minute walk test. However, it does not correlate well with FEV1 (Forced Expiratory Volume in One Second). While the CAT shares some similarities with other questionnaires, there are several important differences. For example, the SGRQ is substantially longer than the CAT, is complex to administer and requires the use of a computer for scoring. The CAT is designed to provide a holistic measure of the impact of COPD on the patient, whereas the MRC dyspnoea scale only measures dyspnoea, and the CCQ only assesses clinical disease control. Thus, the CAT is the only validated, short and simple assessment test which can provide a holistic measure of the impact of COPD on patients, ensuring both the physicians and the patients gain the understanding needed to manage COPD optimally. QoL is defined as an individual's perception of their position in their life in the context of the culture and value systems. Therefore, the extent of understanding of the questionnaire might be influenced by language and ethnicities. Since the validation findings so far have been based on data from the US and Europe, PACE may provide better quality of data across ethnic groups given that mainly Asian subjects will participate in this study. PACE is designed to evaluate whether the CAT has a high predictive value in detecting subsequent exacerbations of COPD. If so, this result might enable both patients and physicians to better target and optimise management. The primary objective is to evaluate the predictability of the CAT to have subsequent exacerbations in COPD patients. Secondary objectives are to evaluate the predictability of the CAT to have moderate to severe exacerbations or time to the first exacerbation, to identify risk predictors for COPD exacerbations, and to evaluate correlations between CAT scores and FEV1 values, or MRC dyspnea scores. An experimental objective is to evaluate the correlation between the CAT score between 2 consecutive follow-ups (e.g. Week 8 & baseline, Week 16 & Week 8) and a COPD exacerbation over the following treatment period adjusting for demographics, MRC scores, lung function parameters, medical history, and therapy history. PACE is a multicentre, prospective, observational study designed to evaluate the predictability of the CAT score to have COPD exacerbations over 24 weeks. During the study, subjects continue taking their regular prescribed treatment. Investigators are free to make medication adjustments where required. Eligible subjects will have a clinic visit every 8 weeks, during which they will complete the CAT questionnaire, the Exacerbation Check List (ECL), MRC dyspnea scale, and spirometry. A regular phone call is placed every 8 weeks in between clinic visits to collect data for the ECL.There is no follow-up period. 550 male and female outpatient subjects will be recruited for PACE to obtain approximately 300 exacerbation events. This study will capture the winter periods in Australia, China, Korea and Taiwan, when incidence of exacerbations is at its peak. Statistical analysis will be performed on subjects' data to derive the PACE end-points.

In this study the possible changes in airway geometry and function induced by 6 month oral treatment with Daxas® (roflumilast) will be evaluated. The use of functional respiratory imaging (FRI) on the phenotyping of chronic obstructive pulmonary disease (COPD) patients will be examined. The study population consists of 40 severe COPD patients, global initiative for chronic obstructive lung disease (GOLD) stages III until IV. Imaging parameters will be assessed and the correlation with lung function and health related quality of life will be checked before and after treatment.

The purpose of this pilot study is to evaluate a remote patient monitoring (RPM) system using a daily PRO tool (EXACT = Exacerbations of Chronic Pulmonary Disease Tool), in preventing hospitalization from Chronic Obstructive Pulmonary Disease (COPD) exacerbations in a COPD population at high risk of exacerbation, compared to those managed by usual care.

The purpose of the investigation is to confirm the ADR development and the contributing factors possibly having an impact on the safety under the post-marketing actual use of Oxis 9 mcg Turbuhaler.

New perceptions about handling and patient satisfaction of the everyday use of Berodual® Respimat® compared to a powder inhaler in patients with chronic obstructive lung disease (COLD). Moreover, further knowledge should be attained about the tolerability of Berodual® Respimat®

The purpose of this study is to determine whether the hospitalized patients with increased waist circumference exhibit cardiorespiratory alterations after chest physical therapy.

Non invasive ventilation (NIV) usually presents air leaks that may determine the result of this treatment. The clinical usefulness of analyzing (and quantifying) these leaks during the adaptation period to NIV has not been evaluated in prospective clinical studies as a predictive data of treatment effectiveness. Our hypothesis is that air leaks are correlated to a successful adaptation to NIV. And air leak magnitude may predict early failures of this treatment. And also, as we do not know if air leaks change during the adaptation period to NIV, we do not know whether early detection of air leaks plays a role in the therapeutic outcome. Our objective is to evaluate the clinical usefulness of quantifying air leaks during the adaptation period to NIV as a predictor of effectiveness of this treatment. We also want to evaluate the correlation between air leaks and clinical-functional patients' profile, and the ventilatory parameters selected and to evaluate air leaks variability during the adaptation period to NIV. Method: We will determine the air leak magnitude in twenty patients during adaptation to NIV. We will use VPAP III ventilators (ResMed, Australia), commercial nasal masks (Mirage o Ultra Mirage) and VPAP III/ResLinkTM (ResMed, North Ryde, Australia), a device that includes a monitoring system coupled with the VPAP III ventilator. This device allows to record air leaks and other ventilation parameters. We will perform four VPAP III/ResLinkTM recordings in each patient (the last night in hospital during the adaptation period, the first night at home, and one and two months later, after the initiation of NIV treatment). We will also perform a complete pulmonary function test, quality-of-life questionnaire (SF36), and a tolerance to NIV questionnaire in all patients at the onset of NIV treatment and two months later. We will evaluate which patients will need to change treatment at the end of the adaptation period to NIV. We also will analyze and compare air leaks magnitude in each of the four recordings stated above.
