Filter by:The primary objective of the study is to assess the safety and tolerability of multiple infusions of andecaliximab (formerly GS-5745) in participants with chronic obstructive pulmonary disease (COPD) as assessed by adverse events (AEs) and laboratory abnormalities.
This is a longitudinal observational study to identify and validate protein biomarkers for COPD (chronic obstructive pulmonary diseases) and cardiovascular disease in smokers and ex-smokers attending primary care. Special emphasize is to correlate biomarkers to different phases of COPD, to progression of the disease, and to treatment of the disease. Furthermore, linkage between COPD, cardiovascular disease, and lung cancer will be investigated by identifying protein biomarkers.
Demonstrate that IMT associated with a conventional pulmonary rehabilitation program allows a significant improvement of dyspnea in subjects with severe or very severe COPD than a conventional pulmonary rehabilitation program alone.
To evaluate in patients with stable Chronic Obstructive Pulmonary Disease (COPD) the efficacy of statins (simvastatin) on: (1) endothelial function; (2) systemic inflammation; (3)BODE (B: body mass , O: bronchial obstruction, D: dyspnea and, E: exercise tolerance) index; (4) Uric acid; and, (5)vascular growth factors. Design: a 12 weeks randomized (1:1), double-blind, placebo control study. Population: 18 males with stable COPD between 40-80 years of age, exsmokers, with Forced expiratory volume in one second (FEV1) between 30 and 80% predicted post-bronchodilation.
Asthma and chronic obstructive pulmonary disease (COPD) are inflammatory airway diseases. Although the clinical features of asthma and COPD may be similar, the pathogenesis of these diseases differs in many aspects. The aim of this study is: - to evaluate airway inflammation in asthma and COPD, - to evaluate airway remodeling in asthma and COPD as compared to healthy subjects, - to assess the relationship between markers of airway inflammation and airway remodeling in asthma and COPD patients. Material and methods: - mild to moderate asthma patients diagnosed in accordance with Global Initiative for Asthma (GINA) guidelines, - mild to moderate COPD patients diagnosed in accordance with Global initiative for chronic Obstructive Lung Disease (GOLD) guidelines, - healthy subjects as controls. Airway inflammation is assessed in induced sputum (IS), exhaled breath condensate (EBC), bronchoalveolar lavage fluid (BALF) and specimens from endobronchial forceps biopsy. Airway wall thickness is evaluated in high resolution computed tomography (HRCT), endobronchial ultrasound (EBUS) and basement membrane thickness (BMT) in biopsy specimens. We plan to compare airway inflammation and features of airway remodeling in asthma and COPD patients.
The purpose of this study is to evaluate the safety and efficacy of roflumilast in the real-use conditions with its registered indications.
Chronic obstructive pulmonary disease (COPD) is one of the most common diseases in the world. In a recent study, we showed that administration of levofloxacin is superior to placebo in the treatment of decompensation of COPD; it is accompanied by a substantial reduction in mortality and a significant reduction in the residence time in hospital. In Tunisia, few data are available on the epidemiology of COPD decompensation. The choice of antibiotic to be used in this situation is challenging to the clinician who must choose between traditional antibiotics (cyclins, aminopenicillins, cotrimoxazole...) and new antimicrobial agents. Recently, it has been emphasized the selection of patients for treatment according to the degree of systemic inflammation (C-Reactive Protein). Indeed, there would have a correlation between the tracheobronchial infection and elevated inflammatory markers. As the elevation of these markers is proportional to the intensity of the inflammatory reaction of the body, is based on the kinetics of these biomarkers in antibiotic treatment seems logical. Thus, C-Reactive Protein allowed not only knowing when to start antibiotics, but also through their kinetic, these markers can guide the duration of therapy and shorten the duration of antibiotic therapy: a rate cut would ensure that the antibiotic treatment was adopted. Available guidelines stated that antibiotic treatment should be maintained at an average of 7 to 10 days while some studies showed no clinical inferiority of courses as short as 3 days. Further reduction of the duration of antibiotherapy was even suggested in order to reduce the risk of adverse events and the pressure that drives bacterial resistance. Hence, we conducted this study using an algorithm to comprehensively evaluate the role of CRP-guided antibiotic prescription in optimizing treatment duration in AECOPD.
Cognitive impairment is a known consequence of cerebral small-vessel disease. Moderate to severe cognitive impairment has been shown in up to 60% of certain individuals with COPD and is likely to profoundly influence an individual's ability to manage their disease. In addition to cerebral small vessel damage and cognitive dysfunction, other organs such as the heart, kidneys, and retina are likely to be susceptible to small-vessel damage in COPD. Several large population studies have shown that COPD is a significant independent risk factor for myocardial infarction, with the effect most marked in early, mild disease. We propose to compare non-invasive MR brain imaging of white matter microstructure (diffusion tensor), cerebral perfusion (arterial spin labelling) and accumulated cerebral small vessel disease (cerebral microbleeds), in COPD patients to smokers without COPD. In addition we plan to explore mechanisms of cerebral small vessel disease in COPD by looking for associations between arterial stiffness, end organ vascular damage and cognitive function.
The purpose of this study is to assess the safety and tolerability of single doses of LAS190792 administered by inhalation to patients with mild persistent asthma and moderate to severe chronic obstructive pulmonary disease (COPD) and also to assess the ability of LAS190792 to produce bronchodilation (opening of the airways).
This study will assess Specialized Community Disease Management (SCDM), an intervention which employs various evidence-based strategies to engage substance using co-morbid patients while in the hospital and follow them into the community via an empirically validated telephone approach as well as contact with a trained community health worker peer specialist. The investigators will first adapt and refine the core SCDM intervention with patient, provider, and stakeholder input through an active community advisory board. The investigators will then conduct a three-year, randomized controlled trial of 222 patients enrolled prior to hospital discharge who are diagnosed with congestive heart failure, pneumonia, acute myocardial infarction, chronic obstructive pulmonary disease, diabetes mellitus, or end-stage renal disease, and a substance use disorder (SUD). Patients will be randomized to either the SCDM intervention or Treatment as Usual (TAU), in which a team of nurse navigators and community health workers follow patients (primarily by telephone) for 90 days post-discharge, but do not address the specific needs of SUDs. The investigators will test the following four hypotheses: (1) patients randomized to SCDM will demonstrate larger reductions in substance use measured by urine-confirmed self-reported days using over the 6-month follow-up compared to patients randomized to TAU, (2) patients randomized to SCDM will attend more specialty substance abuse intervention and treatment sessions over the 6 month follow-up than patients randomized to TAU, (3) patients randomized to SCDM will demonstrate reduced HIV transmission risk behaviors and greater rates of HIV testing over the 6 month follow-up than patients randomized to TAU, and (4) patients randomized to SCDM will experience fewer days of rehospitalization and use of acute emergency services than patients randomized to TAU.
