This research study aims to determine a less invasive way to assess heart function by taking measurements of the heart while subjects are performing an exercise cardiac MRI. Subjects will undergo two exercise phases and MRI measurements will be taken after each exercise phase. These measurements will be compared to available clinical data (including demographic, hemodynamic, radiologic, and functional) and future outcome data.
This is a trial for cardiac sarcoidosis in patients seen during routine clinical care who have not been clinically suspected to have cardiac sarcoidosis according to conventional criteria. The addition of echocardiogram and ambulatory ECG to usual clinical follow-up will be compared. This is a multicenter study, coordinated by the Foundation for Sarcoidosis Research. Up to 12 sites in the US and Europe will participate. Each site will enroll 50 consecutive consenting individuals to a total of 600 enrolled subjects in a randomized trial of additional screening versus usual care.
The purpose of this research study registry is to identify patients with advanced sarcoidosis. This is an observational research study, which means you will not take study medication(s). The study will determine how many and how often patients are diagnosed with advanced disease in sarcoidosis clinics. The study will determine how many and how often patients are diagnosed with advanced disease in sarcoidosis clinics. This study will look at genetic markers; determine the risk factors for advanced sarcoidosis and the natural course of symptoms in advanced disease. You will be in the research study for approximately 36 months (3 years)and will be seen every 6 (six) months during the research study.
This study is being done to learn more about the safety of the drug ATYR1923, to see if taking this drug ATYR1923 will allow you to reduce your steroid dose, and to find out more about the effects of different doses of this drug on the lungs of people who have pulmonary sarcoidosis. This study will also look at how the body responds to the drug. These things will be measured by taking samples of your blood, through medical examinations performed by your study doctor, by lung function tests and by reviewing images of your lungs. This study also includes taking blood samples for biomarkers, antibodies, and tryptase and complement levels. A skin lesion biopsy portion of the study is optional. Participation will last up to 28 weeks. You will have a total of 7 study site clinic visits and 8 telephone contacts during the treatment period.
The purpose of the study is to generate a bio bank of specimens for research. We will tissue that would otherwise be discarded from clinical or surgical procedure and information from medical records. We will also collect discarded blood, urines and sputum. Collecting samples will help to better understanding the mechanisms of cardiovascular diseases, identify biomarkers for early diagnosis and to predict safety and efficacy of new therapies.
You are being asked to take part in this research study because you have been diagnosed with pulmonary sarcoidosis. Sarcoidosis is a disease that can affect the lungs, skin and other organs of the body. Sarcoidosis also involves immune cells which fight bacteria. The purpose of this study is to see if using specific antibiotics will help these immune fighting cells get rid of bacterial proteins and how the antibiotics affect respiratory (breathing) function. The antibiotics used in this study are Levaquin, Ethambutol, Azithromycin, and either Rifampin or Rifabutin. You will by chance be assigned either these medicines or a placebo (an inactive substance).
The purpose of this study is to create and maintain a registry, which is a database (a searchable collection of information) about children, adolescents and young adults with pediatric onset of rheumatic diseases. This data may help in the evaluation of the safety and benefit of medications that are prescribed to patients who have rheumatic diseases.
