This study evaluates safety, tolerability, biodistribution and performance of the [68Ga]Ga-DOTA-Siglec-9 following a single intravenous administration in patients with active rheumatoid arthritis, vasculitis or pulmonary sarcoidosis as well as radiation dosimetry, plasma pharmacokinetics, biodistribution, safety and tolerability of the tracer in healthy volunteers.
Gallium-68 DOTATATE is a radioactive tracer, a type of imaging drug that is labeled with a radioactive tag and injected into the body, which is approved by the U.S. Food and Drug Administration (FDA) to diagnose certain tumors. The study will see how the tracer is taken up in your heart before and after treatment using an imaging scan called Positron Emission Tomography / Computed Tomography (PET/CT). Investigators are doing this research study to find out if DOTATATE can help doctors diagnose people with cardiac (heart) sarcoidosis better as well as serve as a follow-up monitoring tool for a response to therapy.
A phase 2b, open label study to assess the safety and efficacy of increasing doses of pulsed, inhaled nitric oxide (iNO) in subjects with pulmonary fibrosis and sarcoidosis on long term oxygen therapy followed by a long term extension study
PET scanning (positron emission tomography) is a well-established technique used to identify areas of interest within the body. It involves injecting a radioactive tracer which highlights abnormal areas. It has recently been combined with CT (computed tomography) and MRI (magnetic resonance imaging) scanning to more accurately identify abnormalities within the heart. Cardiac sarcoidosis, a condition which causes scarring and inflammation within the heart muscle, is of particular interest. The study makes use of hybrid PET/MR scanning using a designated scanner which enables PET scanning combined with MRI scanning. This will allow imaging of abnormal areas within the heart in this condition alongside treatment regimens in a way which hasn't been done before. If successful, this imaging method will play a key role in diagnosing, quantifying and monitoring these conditions. All participants will undergo PET scanning, where a radioactive tracer is injected into a vein before the scan. The radioactive substance only lasts for a short time and is safe, passed out of the body in urine. The scan will be performed twice; once before treatment and once after treatment has been established. A cohort of healthy volunteers will undergo scanning in exactly the same way to enable us to compare the results with hearts of people who don't have cardiac sarcoidosis.
The present study was designed to assess the efficacy of infliximab in a 2-period study : - An initial period with comparison of infliximab versus placebo and allowing the determination of the primary criteria - Then an extension period in which the 2 arms will receive infliximab (in the placebo group : 5 perfusions and in the experimental group 3 supplemental perfusions). Finally, the 2 groups will receive 5 injections of infliximab There is little evidence in the literature of when and how infliximab should be administered in sarcoidosis. We hypothesized, from our personal experience in 30 cases (18 of which were reported in a retrospective trial (14), that infliximab would have a very quick activity. So it appeared reasonable to evaluate the primary criterion at 6 weeks after initiation of the treatment.
This study evaluates the yield and safety of two different needles for performing endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) in patients with sarcoidosis. The two needles that will be compared will be the 22-gauge ProCore needle and the conventional 22-gauge EBUS-TBNA needle.
This study evaluates the relationship between vitamin-D status and severity of sarcoidosis, and the effects of vitamin-D repletion in vitamin-D insufficient patients with sarcoidosis. Half the patients with sarcoidosis who are vitamin-D insufficient will receive standard vitamin-D supplementation via standard regimen while the other half will receive a placebo. Sarcoidosis patients who are vitamin-D sufficient will also act as controls.
This study aims to (1) evaluate efficacy of UDCA in improving liver function and quality of life; (2) monitor safety, tolerability of UDCA, as well as progression of hepatic sarcoidosis and liver disease, in patients diagnosed with hepatic sarcoidosis. A minimum of 10 subjects will be followed for 12 months. For all subjects, initial 6 months will be observational; in subsequent 6 months, UDCA will be administered. Visits will occur every 3 months and involve routine blood collection.
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.
