Delayed-Enhancement Cardiovascular Magnetic Resonance in Patients With Sarcoidosis
SarcoidosisThe 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.

PET MRI Study in Patients With Cardiac Sarcoidosis
Inflammatory CardiomyopathySarcoidosisMyocarditis or inflammatory cardiomyopathy refers to inflammation of the heart muscle (the myocardium). Sarcoidosis is a multisystem granulomatous disorder that may involve the heart, causing inflammation, and potentially resulting in complications including arrhythmia and sudden death. The objective of this study is to evaluate the diagnostic and prognostic significance of simultaneous combined 18F-FDG PET and cardiac MRI imaging in the evaluation of inflammatory cardiomyopathies including cardiac sarcoidosis. Combined PET/MRI imaging may allow for detection and quantification of active myocardial inflammation as well as chronic fibrosis and scarring. Results of this study may allow for earlier detection of cardiac inflammation when compared with methods in current clinical use, and may lead to better understanding of the disease processes contributing to adverse outcomes. Elucidation of imaging findings associated with future adverse event risk may impact patient management such as providing an indication for pacemaker or defibrillator implantation, or escalation of medical therapy.
Expression and Role of the JAK/STAT Pathway in Sarcoidosis Granuloma Cells
SarcoidosisJAK-STAT Pathway DeregulationRecent studies suggest that the JAK/STAT signaling pathway constitutes a new step in the clinical and therapeutic progress of sarcoidosis. Further investigations are necessary to identify the most suitable patients to receive treatment targeting this pathway, in particular in cases of severe sarcoidosis refractory to the various therapeutic lines.
Endobronchial Ultrasound Strain Elastography in Sarcoidosis
SarcoidosisPulmonaryStrain elastography (SE) is an imaging method used for the measurement of relative tissue elasticity through qualitative (color pattern) or semi-quantitative methods (strain ratio or strain histogram). Very recently, the first pilot study has provided preliminary evidence that EBUS-SE elastography may help identify fibrotic lymph nodes in sarcoidosis and that sampling lymph nodes characterized by low strain elastography, that is "stiff" nodes, is associated with an increased risk of retrieving an inadequate sample (i.e. a sample which is not representative of the lymph node tissue). The investigators hypothesize that an EBUS-SE pattern indicative of lymph node stiffness will be associated with less granulomas and more fibrosis.
Validation of King's Sarcoidosis Questionnaire in a Danish Population
SarcoidosisThe King's Sarcoidosis Questionnaire (KSQ) is a brief questionnaire assessing health status in patients with sarcoidosis. The KSQ was previously validated in English German and Dutch. KSQ will be translated into Danish and validated in a Danish sarcoidosis population.
ACE and HLA Genotypes Predict Severity and Disease Progression in Danish Sarcoid Patients
SarcoidosisSarcoidosis is a multisystem granulomatous disease of unknown cause histologically characterized by noncaseating granulomas. Genetic factors affect disease course, which is highly variable and difficult to predict. This study aims to evaluate the predictive value of ACE and HLA genotypes on disease severity and progression in Danish patients with sarcoidosis.
Risk Indicators of Sarcoidosis Evolution-Unified Protocol
SarcoidosisPulmonaryThe purpose of this study is to develop prediction models that can prognosticate patients with sarcoidosis using clinical data and blood markers that can be obtained during a clinic visit.
