Filter by:The study has been designed to evaluate the clinical application of the new virtual bronchoscopy (VB) -based system for transbronchial sampling of the mediastinal masses or enlarged lymph nodes. The software uses data from thorax CT scan and enables airway segmentation and reconstruction simultaneously with predefined mediastinal targets. The most suitable sites for transbronchial needle aspiration are displayed on the internal surface of the airways showed in VB mode. The diagnostic yield of the new system-assisted TBNA will be compared to the reference method (EBUS-TBNA). The study group includes patients with mediastinal mass or lymph node enlargement in whom diagnostic bronchoscopy and TBNA can be applied as diagnostic methods. Both, virtual bronchoscopy guided transbronchial needle aspiration (VB-TBNA) and EBUS-TBNA of the mediastinal targets are performed during the same diagnostic bronchoscopy. Cytologic material from VB-TBNA and EBUS-TBNA is evaluated by two independent pathologists blinded to the method used to obtain the sample. Diagnostic yield and adequacy of aspirates obtained with the two methods will be assessed and compared.
This study has been designed to provide patients suspected of having cardiac sarcoidosis (CS) with a potentially diagnostic 18F FDG PET/CT. CS is difficult to diagnose with currently available methods, therefore this project will allow access to 18F FDG PET/CT scanning, which may more accurately diagnose the presence of CS. This study will also provide additional data to further examine the effectiveness and safety profile of 18F FDG for this condition. Accurate and early detection is important to allow for better management of CS and improve patient care. The purpose of this study is to provide access to 18F-FDG PET/CT imaging in patients with clinical suspicion of cardiac sarcoidosis, and to collect additional data about the safety and effectiveness of 18F-FDG PET/CT in this patient population
The primary objective of this study was to determine the ability of cardiac magnetic resonance (CMR) to identify cardiac involvement in patients with sarcoidosis. Patients were to undergo CMR in addition to routine clinical evaluation.
The study proposes to evaluate the safety, tolerability, and efficacy of PD 0360324 in subjects with chronic pulmonary sarcoidosis inadequately treated with standard of care therapies.
Diagnosing cardiac sarcoidosis has always been challenging: No single imaging modality has proved effective and cardiac biopsies have a very low sensitivity. 18F-2-fluoro-2-deoxy-D-glucose fluorodeoxyglucose (FDG) PET preceded by at least 12 hours of fasting has previously been demonstrated to have reasonable accuracy, however, in some patients physiological FDG uptake in the cardiac region hampers correct identification of sarcoid granulomas. Gallium Ga 68-DOTANOC is a conjugate of the somatostatin analogue Nal3-octreotide (NOC) and gallium Ga 68-labeled 1,4,7,10-tetraazacyclododecane-N,N',N'',N'''-tetraacetic acid (DOTA). We aim to study whether 68Ga-DOTANOC has superior sensitivity and accuracy than 18-FDG PET in diagnosing cardiac sarcoidosis. In addition, we aim to compare 18-FDG PET preceded by 12 hours fasting with 18-FDG PET during somatostatin blockade of insulin mediated cardiac glucose uptake.
Sarcoidosis is an inflammatory disease of unknown origin that can affect all organs, especially the lungs and mediastinum. Some location of sarcoidosis may require treatment with corticosteroids or immunosuppressors.Although seasonal influenza vaccination can be recommended in sarcoidosis in some subgroups at risk (respiratory failure, pulmonary fibrosis, age over 65, use of immunosuppressive therapy, etc ...), the investigators presently have no data on the efficacy and safety (absence of adverse reactions) of seasonal influenza vaccination in sarcoidosis.Especially it is not known whether the seasonal influenza vaccine provides the same rate and same type of vaccine response in sarcoidosis patients than in the general population. Similarly, it is unclear whether the vaccine response is modified by the severity of the disease and treatment with corticosteroids and immunosuppressors.Based on what is known in systemic lupus and rheumatoid arthritis, which are both inflammatory and autoimmune diseases, the investigators expect at best a 50% vaccine response in patients with sarcoidosis and a 85% vaccination response in healthy controls. The demonstration of a vaccine response could allow reconsidering new vaccine approaches in sarcoidosis.
The main purpose of the present study is to assess whether the sensitivity of Ultrasound-guided Transbronchial Needle Aspiration (EBUS-TBNA) is superior to that of conventional TBNA in the diagnosis of hilar/mediastinal adenopathy and lung cancer staging.
Renal sarcoidosis treatment is based on steroids, but the dose and duration are unknown. Despite this treatment, most patients will have chronic kidney disease. From our previous studies, the investigators believe that high dose steroids by methylprednisolone bolus will improve patient outcome and renal function.
The study aims at assessing diagnostic and therapeutic impact of Rubidium-82 PET in cardiac sarcoidosis.
The purpose of this research study is to learn about the safety of transplanting lungs obtained from non-heart-beating donors (NHBDs) that have been ventilated (attached to a breathing machine or ventilator to deliver oxygen) and perfused with a lung perfusion solution (Steen solution™, made by Vitrolife). This ventilation and perfusion will be done outside the body (ex-vivo) in a modified cardiopulmonary bypass circuit (the kind of device used routinely during most heart surgeries). The purpose of performing ex-vivo perfusion and ventilation is to learn how well the lungs work, and whether they are likely safe to transplant.
