Filter by:The purpose of this research study is to perfect the technique of EVLP and learn about the safety of transplanting lungs 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 lung perfusion and ventilation (EVLP) is to learn how well the lungs work, and whether they are likely safe to transplant.
There are no published clinical consensus guidelines on the treatment of cardiac sarcoidosis. Corticosteroid therapy is advocated by some experts, but is based on small observational studies, with varied clinical response. Objectives of this trial: - to systemically assess the response of patients with cardiac sarcoidosis, to treatment with corticosteroids - to identify the clinical predictors of response to treatment with corticosteroids - to assess the utility of imaging with PET and MRI to predict response to treatment with corticosteroids - to determine the prevalence of cardiac sarcoidosis in young patients with unexplained heart block and in patients with unexplained dilated cardiomyopathy associated with ventricular tachycardia - to use the data from this pilot study to assess the need, feasibility, and sample size for a larger multicentre trial
Sarcoidosis is a granulomatous disease for which the molecular and immunologic association with mycobacteria continues to strengthen. The investigators are interested in conducting a proof-of-concept investigation of the effects of antibiotics on sarcoidosis resolution. The investigators hypothesize that pulmonary sarcoidosis will improve faster if patients are given antimycobacterial therapy, in addition to their standard therapy.
This prospective study was conducted to explore clinical characteristics and outcomes of patients diagnosed with pulmonary sarcoidosis and PH. The investigators also assessed the role of D -dimer levels in these population.
Growing research from independent laboratories provide an association between mycobacteria and sarcoidosis. More recent immunologic and molecular studies demonstrate immune responses to mycobacteria virulence factors. We hypothesize that sarcoidosis pathogenesis reflects an immune response against metabolically-active mycobacterial species. The purpose of this study is to assess if administration of anti-mycobacterial drug therapy will aid in resolution of cutaneous sarcoidosis lesions.
The purpose of this study is to identify patients with cardiac sarcoidosis who may be at risk for sudden death.
Sarcoidosis is a multi-systemic inflammatory disorder of unknown cause characterized by the formation of non-caseating granulomas in involved organs. Its cardiac involvement may be potentially fatal. Although endomyocardial biopsy is required for definitive diagnosis of cardiac sarcoidosis, it is invasive and lacks sensitivity. The specific diagnostic tool for cardiac sarcoidosis is far from satisfactory. Recent studies have revealed that FDG-PET with under fasting conditions is a useful method for identification of cardiac sarcoidosis patients. However, to our knowledge, no investigations have been published with regard to FDG quantification for the diagnosis and management of cardiac sarcoidosis by PET.
This study tests the safety and effectiveness of ustekinumab or golimumab compared to placebo (placebo looks like the drugs being studied, but has no active ingredients). The purpose of this research study is to determine if ustekinumab or golimumab is safe and to determine its effects (good and bad) on patients with chronic sarcoidosis with pulmonary and/or skin involvement. Patients with pulmonary involvement constitute the primary population for analysis, and patients with skin involvement constitute the secondary population; a patient may be in both populations. The study will be conducted at approximately 40 sites globally.
Enlarged glands in the chest (mediastinal lymphadenopathy) is a common problem and may have a variety of different causes. In the past an operation (mediastinoscopy) was required to diagnose the glands. Endobronchial ultrasound (EBUS) is a new procedure that may be able to diagnose these glands without the need for mediastinoscopy. The REMEDY trial aims to examine whether EBUS can reduce the number of mediastinoscopies and healthcare costs in patients with enlarged glands in the chest.
Progressive pulmonary sarcoidosis occurs in up to twenty percent of patients who require persistent treatment, but available treatment options have shown considerable long-term toxicity and uncertain or unproven efficacy. In these patients, pulmonary fibrosis and pulmonary hypertension are common complications which have major prognostic impact. Endothelin-1 (ET-1) has been demonstrated to play a key role in pulmonary fibrosis and pulmonary hypertension, and a potential role in pulmonary sarcoidosis. ET-1 is a potent vasoconstrictor and can promote fibrosis, cell proliferation, and remodeling, and is pro-inflammatory. Preliminary data have shown the therapeutic potential of the endothelin receptor antagonist (ERA) bosentan in sarcoidosis associated pulmonary hypertension. In this light, the therapeutic potential of bosentan as an add-on treatment in progressive pulmonary sarcoidosis needs to be evaluated.
