Filter by:Sarcoidosis is a condition where inflamed cells clump together to form granulomas, which can lead to inflammation or scarring. It can affect any organ of the body, but most commonly affects the lungs. Symptoms can be highly variable, and some patients have no symptoms where as others may develop fatigue or breathlessness. The causes of sarcoidosis are poorly understood. It commonly affects adults in their 30's or 40's. Some patients present with symptoms suggestive of involvement in the airways, such as cough. Inhalers containing steroid are commonly used, but there is a poor understanding of which patients may benefit. Part of the problem is the lack of a sensitive way of measuring these effects and knowledge of how sarcoidosis affects the airways physiologically. The investigators would like to know more about the disease process of sarcoidosis, particularly where it involves the airways. This study will use a number of techniques in order to better understand to disease process. In order to assess whether sarcoidosis produces changes in airway ventilation (and whether these changes are stable or change over a short time period). This pilot study aims to recruit 6 patients who will have magnetic resonance imaging (MRI) with inhaled xenon gas. During this technique, xenon and nitrogen mixture is inhaled and during a subsequent breath-hold, images of the lungs are taken. This creates a detailed view of the lung airway tree, to explore how the disease affects the airways and deeper lung tissue. This technique will be used alongside lung function tests, commonly performed in the laboratory setting and cardiopulmonary exercise testing, to see what happens in the lungs of this group of patients when they reach peak exercise capacity.
This is a multicenter, randomized, double-blind, placebo-controlled, study comparing the efficacy and safety of intravenous (IV) efzofitimod 3 mg/kg and 5 mg/kg versus placebo after 48 weeks of treatment. This study will enroll adults with histologically confirmed pulmonary sarcoidosis receiving stable treatment with oral corticosteroid (OCS), with or without immunosuppressant therapy.
Establish a interstitial lung disease (ILD) registry and biorepository to lead towards a further understanding of the disease.
The investigators will compare endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) with intranodal forceps biopsy (EBUS-IFB) as it relates to the rate of diagnosis of suspected sarcoidosis.
This study sets out to register imaging of small biopsy specimens obtained during bronchoscopy using full-field optical coherence tomography against standard histologic evaluation.
What is the purpose of this research? This study includes two parts based in two NHS specialist centres for cardiac sarcoidosis: - Development of the CARD-SARC: Development of the new questionnaire to measure quality of life in cardiac sarcoidosis patients (the CARD-SARC questionnaire) - Validation of the CARD-SARC: Evaluation of how good the CARD-SARC questionnaire is at measuring quality of life changes in patients with cardiac sarcoidosis.
The Swiss-Ped-IBrainD is a national patient registry that collects information on diagnosis, symptoms, treatment, and follow-up of pediatric patients with an inflammatory brain disease in Switzerland. It was first implemented in 2020 in the pediatric clinic of the university hospital in Bern. Further centers all over Switzerland were opened for recruitment in 2021; Aarau, Basel, Bellinzona, Chur, Geneva, Lausanne, Lucerne, St. Gallen, and Zurich. The center in Winterthur is expected to be open for recruitment by autumn 2021. The registry provides data for national and international monitoring and research. It supports research on inflammatory brain diseases in Switzerland and the exchange of knowledge between clinicians, researchers, and therapists. The registry aims to improve the treatment of children with inflammatory brain diseases and optimizing their health care and quality of life.
PURPOSE: The main purpose is to explore clinical efficacy and safety associated with capsule FMT (cFMT) performed in newly diagnosed, untreated patients with rheumatic and gastrointestinal chronic inflammatory diseases (CIDs). DESIGN AND METHODS: In this 1:1 double-blind, placebo-controlled, randomised, 12-month exploratory trial, 200 patients with at least one of 6 different diagnoses of CIDs fulfilling the study criteria will be enrolled at time of diagnosis. The patient groups are: rheumatoid arthritis (RA), ankylosing spondylitis (AS), psoriatic arthritis (PsA), pulmonary sarcoidosis (PSar), Crohn's disease (CD), and ulcerative colitis (UC). The primary endpoint is change from baseline to eight weeks in the physical component summary (PCS) of the short form health survey (SF-36). Key secondary clinical endpoints will be evaluated at 8 weeks. Other secondary clinical endpoints will be evaluated at 52 weeks and reported in secondary papers. The baseline visit will be performed as quickly as possible after the patient's informed consent has been obtained to ensure no unnecessary treatment delay. Stratified by CID diagnosis, patients will be randomised (1:1) to either placebo or single-donor cFMT processed from stool provided to the hospital from anonymous-to-the-patient healthy donors. The experimental intervention FMT/placebo will be repeated once weekly the first month (i.e., each patient will receive a total of four treatments). In addition, all participants will concomitantly be offered the national guideline first-line anti-inflammatory treatment following the baseline visit. At baseline, 8 weeks, 26 weeks, and 52 weeks a thorough clinical examination will be conducted and all relevant clinical scores for each disease entity will be registered. Patient-reported-outcomes including SF-36 and disease specific questionnaires will be collected at week 1, 2, 3, 4, 8 (primary endpoint evaluation), 26 and 52. Adverse events will be monitored through out the trial.
Neurosarcoidosis represents up to 10% of sarcoidosis cases. Little is known about its long-term course, even if the disease remains mainly monophasic with/w.o. sequelae, or if bouts of new symptoms may arise over years (polyphasic). Using retrospective data from patients diagnosed with neurosarcoidosis in three French referral centers for neuro-inflammation, the investigators aim to determine patterns of disease course, according to the initial presentation and the treatments used.
Strain 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.
