Filter by: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.
The purpose of this study is to develop a clinical dataset of sarcoidosis patients with a diagnosis of cancer who are categorized by date of birth, sex, race/ethnicity, clinical information, laboratory and imaging information, time of sarcoidosis onset, cancer type and treatment, time of cancer diagnosis, stage and grade.
Evaluate MyoStrain cardiac MRI pulse sequence in Clinical practice
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).
This study aims to evaluate the efficacy and safety of inhaled treprostinil in subjects with sarcoidosis-associated interstitial lung disease and pulmonary hypertension.
The purpose of the study is to determine the characteristics of patients with diabetes and sarcoidosis and to compare them with those of patients with diabetes and no sarcoidosis. The investigators will approach these aims by measuring hemoglobin A1c, C peptide, insulin levels, and 2-hour glucose tolerance test results on the study population as well as collecting clinical data from records. Three groups of patients will be identified from pulmonary and endocrinology clinics at the University of Alabama at Birmingham. The first group will have a diagnosis of sarcoidosis without diabetes, the second group will have a diagnosis of both sarcoidosis and diabetes, and the third group will have a diagnosis of diabetes without sarcoidosis. Sample size is not pre-determined, but investigators anticipate this number to be less than 100. These patients will be asked in person during an office visit to join the study. For each patient who agrees to join, at a clinic visit, investigators will review and sign consent. Following the visit or at a time convenient for each patient, study subjects will undergo a fasting plasma venous sample collection for a hemoglobin A1c, C peptide, insulin level and perform a 2-hour oral glucose tolerance test. The degree of glucose intolerance and prevalence of diabetes will be analyzed and compared between the groups and to historical published control data via T test comparisons. At a later separate visit, patients recruited will undergo ultrasound of the pancreas to assess pancreatic size and morphology.
This is a pilot study to determine whether further research is warranted to assess whether tofacitinib is an effective steroid sparing treatment for pulmonary sarcoidosis. The primary endpoint for this study is a 50% or greater reduction in corticosteroid requirement.
