Filter by:Pulmonary sarcoidosis (PS) is defined as a multisystem granulomatous disorder of unknown cause affecting different vital organs, especially the lungs. PS manifest in reduction of pulmonary function. Overall symptoms lead to poor physical conditioning contributing to a vicious cycle of more physical inactivity. Treatment of sarcoidosis is usually limited to patient symptoms. Progressive fibrosis sometimes can lead to respiratory failure and ultimately, pulmonary transplantation. Physical training shows promising evidence of a positive effect on PF. No defined training program with regard to exercise frequency, duration or intensities exists. PS is a relatively rare disease and patients are scattered in great geographically areas,.It is difficult to organize targeted group training with supervised physical training, convenient for patients and affordable for the public health sector. Tele-rehabilitation (TR) seems to be a good approach to reach patients in low inhabited areas, going from health care to self-care, empowering patient's awareness of their disease and increasing the flexibility patients need to acquire healthier behaviors. Preliminary evaluations from TR initiatives in Scotland showed tele-rehabilitation to be more cost effective with patients living in remote areas than with the outreach- or centralized model. No studies on the feasibility effect of TR in PS exists. The study is a prospective randomized controlled trial investigating the effects of tele-rehabilitation in patients with PS compared to standard practice. 24 patients with PS will be randomized in two groups, trained by tele-rehabilitation for 12 weeks and afterwards followed for 6 months. The control group will follow the usual control program for PS patients that only involves outpatient visits approximately every 3rd month. No specific PS rehabilitation program exists. The intervention group will receive TR in the form of video consultations- and chat sessions with a real physiotherapist and workout sessions with a virtual physiotherapist agent. They will also train with virtual reality glasses or tablets that show the actual exercises in the training program. Patients will be tested with pulmonary function, physical, anxiety and quality of life parameters, all at baseline, after 12 weeks of intervention, 3 and 6 months after cessation of the program.
This protocol is an unblended randomized screening trial will have consecutive patients with no suggestion of cardiac sarcoidosis according to usual screening enroll in an enhanced screening protocol. The routine clinical care is to gather patient's history of symptoms and under go an ECG. If a patient has an abnormal results in standard screening, they typically have further evaluations as part of their routine medical care. These tests might include an echocardiogram, ambulatory ECG, and advanced cardiac imaging (MRI, PET scan as per local practice). A patient that has normal results on standard screening will be randomly assigned to enhanced screening at each center. Half the patients will be randomized to usual follow-up (annual symptom assessment and ECG) and the other half will be assigned to the enhanced screening (echocardiogram and ambulatory ECG at enrollment and at 24 months). The investigators hypothesize that screening using conventional history, physical and ECG in the general sarcoidosis population, followed by appropriate advanced imaging testing, will result in the identification of a higher percentage of ascertained cardiac sarcoidosis than has been reported historically (2-5%). The investigators hypothesize that routine use of echocardiogram with strain and ambulatory ECG will identify additional patients who will have advanced imaging abnormalities or who meet criteria for cardiac sarcoidosis. The investigators further hypothesize that re-screening patients after 24 months with repeat echocardiogram and ambulatory ECG will identify additional patients with suspicion for cardiac sarcoidosis who had no abnormalities on the standard screening tests.
Evaluate the feasibility of performing a multi-elemental imaging analysis of lung specimens from patients with ILDs, with an technology named LIBS (Laser Induced-Breakdown Spectroscopy)
Sarcoidosis is a systemic disease with unknown etiology. Chronicity of the disease is observed in 1/3 of cases. Five percent of the affected patients are expected to die due to pulmonary worsening. After pulmonary complications, ocular complications are one of the most frequent complications. In hospital setting 2 to 15% of patients who come for initial uveitis diagnosis are after examination due to Sarcoidosis. Sarcoidosis diagnosis is based on paraclinical exams (biological, radiography) and histological confirmation. Corticotherapy (local or general) is usually used to cure sarcoid uveitis. In case of failure immunosuppressor or anti-tumor necrosis factor (TNF) can be used. In 10% of cases ocular symptoms including blindness are observed. Only treatment administrated quickly after diagnosis of sarcoid uveitis can prevent from ophthalmologic complications. The main objective of the Lyon Sarcoid Uveitis Cohort study is to analyze the relevance of the paraclinical exam for sarcoid uveitis diagnosis, and to define a better visual and extra-ophthalmologic prognosis and describe the therapeutic practice in our Department. This study is proposed to all patients diagnosed with Sarcoid uveitis with a histological confirmation and referred to the internal medicine department of the Croix-Rousse hospital, Lyon, France, for etiologic diagnosis or treatment.
Sarcoidosis is a multisystem granulomatous disease of unknown cause that can affect any organ in the body, including the heart. Granulomatous myocarditis can lead to ventricular dysfunction and ventricular arrhythmias causing significant morbidity and mortality. Immunosuppressive therapy (IST) has been shown to reverse active myocarditis and preserve left ventricular (LV) function and in some cases improve LV function. In addition, IST can suppress arrhythmias that develop due to active myocarditis and prevent the formation of scar. The potential role of cardiac biomarkers, including brain natriuretic peptide (BNP), atrial natriuretic peptide (ANP), and cardiac troponins, in detecting active myocarditis is limited and studies have been disappointing. At present, there are no biomarkers to detect active myocarditis and the use of advanced imaging modalities (FDG-PET) for assessing and monitoring active myocarditis is not feasible or practical and is associate with high radiation exposure. As such, a biomarker that is reflective of active myocarditis and that is cardiac specific will assist physicians in assessing the presence of active myocarditis to guide therapeutic decisions and to assess response to therapy which can limit further cardiac damage. Cell free DNA (cfDNA) are fragments of genomic DNA that are released into the circulation from dying or damaged cells. It is a powerful diagnostic tool in cancer, transplant rejection and fetal medicine especially when the genomic source differs from the host. A novel technique that relies on tissue unique CpG methylation patterns can identify the tissue source of cell free DNA in an individual reflecting potential tissue injury. We will be conducting a pilot study to explore the utility of this diagnostic tool to identify granulomatous myocarditis in patients with sarcoidosis.
This study aims to evaluate the efficacy and safety of inhaled treprostinil in subjects with sarcoidosis-associated interstitial lung disease and pulmonary hypertension.
Registry with evaluation and genetic information of patients with advanced sarcoidosis and matched sarcoidosis
Prospective randomized controlled trial comparing low dose Prednisone(or Prednisolone)/Methotrexate combination to standard dose Prednisone(or Prednisolone) in patients diagnosed with acute active clinically manifest cardiac sarcoidosis and not yet treated. The Investigators hypothesize that low dose Prednisone(or Prednisolone)/Methotrexate combination will be as effective as standard dose Prednisone(or Prednisolone), and result in significantly better quality of life and less toxicity than standard dose Prednisone(or Prednisolone).
The guided FNA by endobronchial ultrasound ( Endobronchial Ultrasound guided transbronchial Needle Aspiration or EBUS-TBNA) is a minimally invasive technique with an established role in the staging of lung cancer 1, and in the evaluation of intrathoracic lymph node metastases from extrathoracic primary cancer2 . There is also a role in cases of isolated hilar and mediastinal lymph nodes in which the differential diagnosis includes mostly sarcoidosis, lymphoma and tuberculosis. 3 Various studies have evaluated more recently the diagnostic yield of EBUS-TBNA specifically for sarcoidosis 4 and thoracic lymphoma 5-6. Although there is emerging data supporting the usefulness of EBUS-TBNA in the investigation of these two pathologies, the efficacy results vary according to the target populations and certain parameters. Moreover, although a large randomized study demonstrated e superiority of EBUS-TBNA over conventional bronchoscopic sampling methods [ bronchoalveolar lavage (BAL) and trans-bronchial biopsies (TBB ] for the diagnosis of sarcoidosis , 7 the results suggest that there is still room for optimizing the performance of EBUS-TBNA [b] . In the field of lymphoma, obtaining large enough specimens for adequate subtyping also remains a concern. 8 In order to improve the performance of EBUS -TBNA , new needles have been developed with the aim to provide biopsies for histological evaluation rather than purely cytological. The ViziShot FLEX © (Olympus) 19 gauge needle (19 gauge or 19G) is a large needle, which can provide both tissue and needle aspiration , and has the advantage of being more flexible. For this study, the investigators want to compare the diagnostic yield of EBUS-TBNA using needle ViziShot FLEX 19G (1.11 mm) with that of the standard 22G needle ( NA-201SX; Olympus) , in the investigation of hilar or mediastinal lymphadenopathy suspected to be sarcoidosis or lymphoma.
This is a single centre exploratory study that aims to apply hyperpolarized xenon-129 (129Xe) magnetic resonance imaging (MRI) methods and measurements in individual patients with and without lung disease to better understand lung structure and function and evaluate response to therapy delivered as a part of clinical care.
