Filter by:The primary purpose of this study is to investigate the efficacy and safety of oral antimycobacterial therapy in patients with confirmed progressive pulmonary sarcoidosis. We suspect that the CLEAR regimen will improve the absolute FVC percent predicted in chronic pulmonary sarcoidosis participants.
In a study of Cardiac sarcoidosis, a serious heart condition, a radiotracer is being used to examine inflammation.
Flexible bronchoscopy is a common procedure performed by pulmonary physicians. The use of topical anesthesia, analgesia, and sedation during flexible bronchoscopy varies among physicians, institutions and geographic locations across the globe. Commonly used topical anesthetic agents before and during bronchoscopy include cocaine (4%),benzocaine (20%), tetracaine (1%), and lignocaine (1%-10%). Topical lignocaine is administered through the flexible bronchoscope in an attempt to reduce excessive coughing and patient discomfort. However, the optimal dosage and strength of topical lignocaine that should be used during fibreoptic bronchoscopy has long been a topic of controversy. In this study we compare the efficacy of 1% versus 2% lignocaine in controlling cough and pain in patients undergoing flexible bronchoscopy.
This trial examines whether low grade suppression of the initial inflammatory process of sarcoidosis by intervention with low-dose dexamethasone therapy achieves significant alleviation of (sub-)acute symptoms, improvement in quality of life, increase in work productivity, and whether this intervention prevents disease progression and reduces total health-care costs.
The investigators hypothesize that conventional or EBUS-TBNA will have equal efficiency in diagnosing sarcoidosis when performed in conjunction with endobronchial and transbronchial lung biopsy.
There is currently no experimental model that accurately represents sarcoidosis. The lack of a useful research model significantly slows progress towards developing new treatments for sarcoidosis. The investigators plan to develop a new model for sarcoidosis research and will test the model to see if it helps us understand how sarcoidosis develops and if it is useful for testing new treatments.
The development of endobronchial ultrasound (EBUS) and EBUS-guided transbronchial needle aspiration (EBUS-TBNA) has improved the safety and diagnostic accuracy of the mediastinal lymph node (MLN) sampling. Still, in some diseases routine cytological specimens are considered insufficient and histological sampling is preferred. The aim of the study is to compare the diagnostic accuracy of EBUS-TBNA and two other, more invasive procedures to obtain histological samples from MLN in patients with clinical and radiological features of sarcoidosis. Bronchoscopy with bronchoalveolar lavage (BAL), EBUS-TBNA, EBUS guided transbronchial forceps biopsy (EBUS-TBFB), large bore (19G) histology TBNA as well as endobronchial forceps biopsy will be performed in 90 consecutive patients with mediastinal lymph node enlargement and clinical and radiological features of sarcoidosis. Diagnostic accuracy of each sampling technique will be calculated and compared to other techniques. Diagnostic yield of different technique combinations will also be calculated and the most efficient diagnostic approach will be defined.
This project is designed to address the following hypothesis: Distinct patterns in lung microbiome are characteristic of sarcoidosis phenotypes and reflected in changes in systemic inflammatory responses as measured by peripheral changes in gene transcription. The Specific Aims are: 1. To identify peripheral blood mononuclear cell (PBMC) gene expression patterns that characterize distinct sarcoidosis phenotypes. 2. To determine whether patterns in the lung microbiome are associated with sarcoidosis severity and disease phenotypes 3. To correlate mRNA and microRNA expression patterns in sarcoidosis affected organs with changes in microbiome, clinical parameters and PBMC gene expression patterns 4. To integrate clinical, transcriptomic, and microbiome data to identify novel molecular phenotypes in sarcoidosis.
Pulmonary sarcoidosis patients with fibrosis often develop recurrent episodes of bronchitis. These can lead to worsening of disease for both the short and long term. Roflumilast has been shown to reduce the number of acute bronchitis episodes in patients with COPD. Drugs similar to Roflumilast have been shown to help sarcoidosis. The current study is to determine if Roflumilast will reduce number of episodes of bronchitis and help fibrotic sarcoidosis.
The purpose of this study is to apply the MELISA test, that diagnose hypersensitivity to metals, in Sarcoidosis patients with occupational exposure.
