Sarcoidosis is a multi-systemic granulomatous disease of unknown cause that is characterized by the formation of non-caseous epithelioid cell granulomas. Sarcoidosis involves the respiratory system in \> 90% of cases, usually the hilar and mediastinal nodes, and, less frequently, the lung tissue. Airway involvement, as judged by clinical features, physiologic testing, imaging techniques, bronchoscopy, and airway mucosal biopsy, has been observed in nearly two-thirds of patients with sarcoidosis. Although sarcoidosis involving thoracic lymph nodes and pulmonary parenchyma is familiar to most clinicians, airway involvement is often overlooked. The frequency of airway involvement increases as the parenchymal disease progresses, and\\airway involvement is associated with increased morbidity, respiratory symptoms, and mortality. The initial airway abnormality is the inflammation manifested by mucosal edema, erythema, and the formation of granulomas. As the airway disease progresses, the mucosa may demonstrate granularity, nodularity, cobble stoning, and friability. Sarcoid granulomas tend to develop along the bronchovascular bundle or in the vicinity of the airways. Overall quality of the endobronchial biopsy (EBB) will depend on the method by which it is obtained and cryo-EBB will most likely to provide better tissue for the diagnosis in comparison to forceps biopsy which has smaller sample as well as crush artifacts. Therefore, it is hypothesized that cryo-EBB will be better than forceps EBB and combined together it will increase the overall diagnostic yield of the sarcoidosis when combined with lymph node sampling by endobronchial ultrasound guided trans-bronchial needle aspiration (EBUS-TBNA). 1. Primary objective: To compare the diagnostic yield of cryo-EBB with forceps biopsy in patients undergoing routine EBUS-TBNA for suspected sarcoidosis. 2. Secondary Objective: To evaluate the overall diagnostic yield of combined endobronchial biopsy and EBUS-TBNA in patients undergoing routine EBUS-TBNA for suspected sarcoidosis. The relevance and the expected outcome of the proposed study 1. The study will provide insight to obtain an endobronchial biopsy either with cryo probe or forceps 2. The study will also provide information regarding overall increase in diagnostic yield if any when the endobronchial biopsies are combined with EBUS-TBNA.

Inhalation of beryllium can induce specific sensitization and diffuse pulmonary granulomatosis called chronic beryllium disease (CBD). The clinical, radiographic, and anatomopathological features of CBD are very similar to those of sarcoidosis, another granulomatosis, making its diagnosis difficult. In addition, the progression of CBD is poorly understood. The investigators hypothesis is that there are specific clinical, biological, anatomopathological, and radiological presentation specificities of CBD, as well as a worse prognosis compared to pulmonary sarcoidosis.
NCT03824392
This randomized, double-blind, placebo matched to efzofitimod-controlled, study will evaluate the safety, tolerability, immunogenicity, pharmacokinetic (PK), and preliminary efficacy of multiple ascending doses of IV efzofitimod in participants with pulmonary sarcoidosis undergoing a protocol-guided oral corticosteroid (OCS) tapering regimen.This study will consist of 3 staggered multiple dose cohorts. Each eligible participant will participate in only one cohort during the study. Within each cohort, 12 participants will be randomized 2:1 to efzofitimod (N=8) or placebo matched to efzofitimod (N=4).
NCT03599414
Sarcoidosis is a disease of unknown cause which affects adults of all ethnic backgrounds. Clumps of tissue called granulomas develop primarily in the lungs, but can damage other organs, especially the heart. Anecdotal evidence from autopsy studies suggests the heart is affected in up to 68% of patients, but there is much uncertainty about this figure. If undetected and untreated, it can lead to serious complications or even sudden death. The current recommendation is to perform heart tracings (ECG s) on all patients, but this detects fewer than half of those with heart involvement. Blood markers traditionally used to diagnose heart disease are unreliable, meaning there is no simple blood test in use. The investigators propose a study with three aims. Firstly, identify the true prevalence of heart disease by performing Magnetic Resonance Imaging (MRI) scans on a group of patients with newly diagnosed lung sarcoidosis. Those found to have heart disease will have specialist (but routine) electrical heart tests. Secondly, (and perhaps the most immediate and clinically relevant) to identify the best method of diagnosing heart involvement using a combination of three simple tests: advanced ECG, 24-hour continuous ECG and a new type of computerised ultrasound scan. Thirdly, to identify proteins in the blood that could be used to develop a simple blood test for heart involvement in patients with lung sarcoidosis.
NCT04173689
This is an educational work. Thirty patients with pulmonary sarcoidosis will be included in the study and randomly selected into two training groups.One group will receive home inspiratory muscle training (IMT) for 15 minutes, twice a day, 7 days a week with the resh Threshold IMT 'device. In the IMT group, the initial training intensity will be determined by measuring the maximal inspiratory muscle strength (MIP) with the intraoral pressure measuring device, 30% of the measured (MIP) value will be started at the first evaluation and the new training intensity will be determined by calculating 30% of the measured value by repeating the MIP measurement every week. The other group will perform upper extremity and trunk exercises combined with respiratory exercises at home for 7 days, twice a day for 15 minutes.Patients will be evaluated before the training program and 8 weeks after the training. In the first evaluation, demographic information and clinical characteristics of the patients will be noted.In this study, upper and lower extremity exercise capacity, respiratory functions, peripheral muscle strength, dyspnea, fatigue, sleep quality, cognitive function, daily living activities, physical activity level, anxiety, depression, upper extremity and trunk exercises combined with inspiratory muscle training in patients with sarcoidosis and the impact on quality of life.

Corticosteroids are presently the drug of choice for the treatment of pulmonary sarcoidosis. However, corticosteroids are associated with many significant side effects. For this reason, it would be beneficial to find an alternative agent to corticosteroids for the treatment of pulmonary sarcoidosis. This study is an open label trial of mycophenolate for new onset pulmonary sarcoidosis. Patients are candidates for this study if they have biopsy proven pulmonary sarcoidosis and a vital capacity or FEV1 less than 80% of predicted. Patients must undergo bronchoscopy where not only is the diagnosis of pulmonary sarcoidosis required, but in addition, cells are obtained from bronchoalveolar lavage. If the patients are diagnosed with pulmonary sarcoidosis, they are placed on an initial dose of 500mg BID of mycophenolate for 1 week. If their blood counts are not affected on this dose and they have no significant symptoms that are thought to be drug related, then their dose is escalated to 1g BID for the remaining 9 weeks of the study (the total study drug therapy time is 10 weeks). The patients are followed with multiple study visits. At these visits blood tests are drawn to make sure that there are no significant side effects from mycophenolate. In addition, the patients have a history and physical performed to evaluate the clinical state of their sarcoidosis and to detect mycophenolate side effects. On completion of 10 weeks of mycophenolate therapy, the patients undergo a second bronchoscopy with bronchoalveolar lavage to obtain cells for analysis. The patients are evaluated with spirometry, measurements of shortness of breath (dyspnea), and a quality of life scale (SF36) at serial visits during their study. The primary endpoint of the study is improved, unchanged or worse FVC. It is hoped that this pilot study will suggest that mycophenolate is a reasonable treatment option for new onset pulmonary sarcoidosis.

Sarcoidosis is a disease most commonly affecting the lungs, but it can also involve lymph nodes, skin, liver, spleen, eyes, bones, and glands. The cause of the disease is unknown. When it occurs it can produce an inflammatory reaction leading to irreversible organ damage and disability. In sarcoidosis granulomas can form in various organs (primarily lung) which can lead to its dysfunction. Granuloma is formed by clusters of inflammatory cells. The formation of these granulomas is influenced by the release of a substance called TNF-alpha (tumor necrosis factor alpha) which is found in some white blood cells. A drug known as pentoxifylline (POF) is known to markedly reduce the release of TNF-alpha. The standard medical treatment for sarcoidosis is steroid therapy. However, steroid therapy is associated with significant side effects and often must be stopped. Unfortunately, some of these patients can relapse when the steroid therapy is discontinued. Because of this, researchers are interested in finding alternative therapies for the treatment of sarcoidosis. This study will evaluate the effectiveness of giving POF to patients with sarcoidosis currently taking steroids. Researchers will compare the results between patients taking steroids with pentoxifylline and those patients taking steroids alone.
