Filter by:The purpose of the study is to determine whether the excretion of renal water- and salt-channels in the urine reflects the handling of water and salt in the kidneys, and whether the excretion can be used to monitor and/or predict the effects of treatment of certain heart or lung diseases.
This study (A7881006) is the first multiple dose study in moderate asthmatic subjects and aims to determine the safety and efficacy of PF-00610355 when subjects take PF-00610355 on a daily basis for 4 weeks in subjects maintained on inhaled corticosteroid.
The purpose of this study is to assess the effect of inhaled beclomethasone (an inhaled corticosteroid) on the pattern of the lung airway epithelium and alveolar macrophages gene expression of healthy smokers. We hypothesize that the administration of beclomethasone will result in reversibility of some of the airway epithelium and alveolar macrophage gene expression changes induced by cigarette smoking.
Bone-marrow-derived progenitor cells (EPCS) play an important role in neovascularization and tumor growth. In lung cancer, angiogenesis is an important event in mechanisms of tumor proliferation and metastasis. Recent evidences suggest that EPCS can be recruited and differentiate in mature endothelial cells to form new blood vessels. The role of EPCs in NSCLC is unclear. In contrast, angiogenic drugs are proposed combined to systemic chemotherapy in NSCLC. The aim of this study is to identify EPCs in peripheral blood from patients with NSCLC, by comparison to Chronic Pulmonary Obstructive Disease (COPD), an inflammatory disease.
Nowadays it has become evident that a chronic systemic inflammation is present in patients suffering from chronic obstructive pulmonary disease (COPD). The role of the nuclear enzyme poly(adenosine diphosphate-ribose)polymerase (PARP) as a key mediator within these systemic inflammatory processes as well as in COPD associated exercise intolerance and muscle weakness could recently been identified. The attenuating effect of dietary ingredients with PARP inhibiting activity on systemic inflammation was supported by data from in vitro and in vivo studies, from other groups as well as from our own lab. We identified several caffeine metabolites as potent inhibitors of the most abundant PARP-isoform PARP-1 in-vitro, in animal models as well as in ex-vivo experiments with whole blood from COPD patients. However, clinical data with respect to their anti-inflammatory effects in COPD patients are currently not available for none of these substances. Therefore, the current clinical pilot study is intended to establish for the first time clinical data (proof of principle) on the anti-inflammatory potential of caffeine metabolites.
We hypothesize that ongoing and more severe airway inflammation in COPD may result from the impairment in activation of innate immune response
Recent guidelines on pulmonary rehabilitation (PR) recommend upper extremity exercise training (UEET) in patients with chronic obstructive pulmonary disease (COPD). The theory supporting the inclusion of upper extremity exercise training in the pulmonary rehabilitation for these patients, is based on the profound understanding of the activity of the accessory respiratory muscles, which are competitively involved in both the support of the upper extremities during activities and the ventilation. However, a systematic review of the literature carried out by our staff reveals that the clinical trials carried out up to now to verify the effectiveness of UEET are of poor methodological quality and the investigators cannot corroborate the recommendation recently made on the basis of the results of the investigators' review. Therefore the investigators began this randomized, parallel groups, controlled clinical trial with the purpose of determining the short-term effect of unsupported UEET on the performance of the upper extremities and on symptoms perceived during activities by patients with COPD.
The purpose of the study is to assess the safety and the effect of treatment by PulseHaler™ on patients with COPD, as measured by the change from baseline in full pulmonary functions, oxygen saturation, exercise tolerance and health related quality of life; and to assess the ease of use of PulseHaler™ by the patients.
This study compared the safety and efficacy of indacaterol 150 µg taken once daily (o.d.) versus salmeterol 50 µg taken twice daily (b.i.d) in patients 40 years old or older with chronic obstructive pulmonary disease.
The presence of an abnormally increased pulmonary blood pressure worsens the prognosis of patients with interstitial pulmonary disease. The aim of this study is to estimate the frequency of an increased blood pressure in the lungs among patient with interstitial pulmonary disease, and to evaluate the use of different biomarkers in diagnosis of the condition.
