Active clinical trials for "Lung Diseases, Obstructive"

The investigators assume that by analysis of different volatile organic compounds in the breath, using nanotechnology, the investigators will be able to identify a unique respiratory signature of different diseases including asthma, chronic obstructive pulmonary disease (COPD) and pulmonary hypertension.

The primary objective of this non-interventional study is to evaluate daily symptom variability in COPD patients. The secondary objectives are; to evaluate effects of COPD symptoms on the morning activities of patients, to determine therapeutic expectations of patients and physicians in COPD, to determine which and how frequent non-drug approaches are recommended in order to prevent COPD exacerbations, to define COPD patient profiles about the below-mentioned issues: Demographic characteristics, Disease characteristics, Concomitant diseases and implemented drug treatments. All patients, who apply to the study physicians and fulfill all patient selection criteria during patient enrolment period, will be included. Patients, who provide all of the following measures will be included in the study: To apply to a physician for outpatient treatment for any reason, Age over 45 years, being diagnosed with COPD, being a smoker or used to be a smoker once (> 10 package years), to give consent for the use of their medical data. The patients that exhibit the following exclusion criteria will be excluded from the study: COPD exacerbations still on-going or experienced in the last 3 months (Exacerbation is defined as worsening of COPD symptoms leading to antibiotic and/or short-term oral steroid treatment and/or hospitalization or admission to the emergency unit.); Presence of lung cancer or an important respiratory disease such as bronchiectasis, pulmonary fibrosis, interstitial pulmonary disease, tuberculosis, sarcoidosis; Participation in an interventional clinical trial at present and Enrollment in this study once. In this study, patients will be recorded at their visit to the physician and there will be no follow-up thereafter.

This study is intended to be an evaluation of the properties of human sputum collected from patients with COPD. It is hypothesized that cationic airway lining modulators will have beneficial effects on the rheological properties of sputum derived from patients with COPD. Approximately 10 patients with COPD will collect sputum at home for 5 days. Samples will be collected and tested in laboratory tests.

Cigarette smoking, the major risk factor for COPD, causes not only airway and lung inflammation, but also systemic effects. These systemic effects of smoking could substantially contribute to the development of chronic diseases, other than COPD, particularly chronic heart failure (CHF). The aim of this project is to assess the frequency and severity of CHF and COPD in outpatients with history of smoking referred to Hospital because of dyspnea and/or chronic cough.

Aspects of confocal laser micro-endoscopy (CLME) and morphometry in chronic obstructive pulmonary disease (COPD) and lung transplant recipients is described and will be correlated with clinical findings in order to described small airway remodelling in these patients.

Chronic obstructive pulmonary disease (COPD) determines an important risk of disability and disease-related need of care. Selected interventions were able to reduce the number and the severity of exacerbations. Telemedicine has also been proposed for this purpose. Current evidences, however, are scant. The investigators present a randomized, parallel-group trial of a multiparametric remote monitoring system to test its ability to improve early exacerbation detection rates and impact on clinical outcomes.

Substance P is released from sensory nerves and transmits pain information into the central nervous system. As pain and dyspnea share many characteristics, including similar neurological pathways, it is possible that substance P may contribute to the sensation of dyspnea. The hypothesis of the study is that patients with chronic obstructive pulmonary disease (COPD) will provide lower ratings of breathlessness during resistive load breathing with oral aprepitant, a medication that blocks the activity of substance P, compared with placebo.

Muscle weakness and atrophy are important consequences of chronic obstructive pulmonary disease (COPD). Although resistance exercises increase strength and muscle mass in patients with COPD, the response to training appears to be suboptimal in these individuals. A dysregulation in the signaling pathways involved in the regulation of muscle mass could play an important role in this phenomenon. Hypothesis: Proteins involved in muscle mass regulation will be less activated in the quadriceps of patients with COPD following the acute bout of resistance training exercise compared to healthy age-matched controls.

The UK population is ageing and the likelihood of having a long term health condition increases with age. Three out of every five people over 60 in the UK have a long term condition. Ageing and having a long term condition increases the chance of having difficulty being independent and carrying out day to day activities. In recent years the NHS has made a greater effort to prevent these difficulties in patients with long term conditions. One approach to help patients with long term conditions is case management, where by (usually) a community matron visits patients at home, looking for early warning signs of any worsening of their condition and arranging care and treatment. But the current way this is done varies across the country and hospital admissions are still rising. In order to give the right care at the right time, effective monitoring is needed to help the community matron detect and act on changes in the patient's condition. Loss of muscle strength in old age is linked to a poor health, but it is not known whether simple measures of muscle strength could be used to detect and predict declines in health in the short to medium term to help maintain independence and prevent an accident or hospital admission. The aim of this study is to look at whether monitoring muscle strength in case managed patients is practical, acceptable and useful in detecting when a patient's condition worsens. Each patient will be visited by the researcher in their home twice in the first week, then once every two weeks, for another 5 weeks, to carry out three simple measures of grip and respiratory strength, and complete questionnaires about their health and ability to carry out day to day activities. Each visit will last about 20 to 30 minutes. A small group of clinicians will be asked about their views of the strength measures. Database analysis will allow descriptive data on the patient group to be gathered and analysed.

The purpose of this study was to examine the characteristics of patients selected for treatment with roflumilast and the effectiveness and safety of roflumilast in patients with severe or very severe COPD treated in Hospital and outpatient specialist ward settings in Greece.
