the PHENOSAR Trial: Use of Antibiotics in Treatment of Sarcoidosis
SarcoidosisPulmonary1 moreIn this study it is investigated whether treatment with azithromycin in combination with doxycycline reduces the bacterial load of C. acnes in granulomatous tissue of patients with sarcoidosis and subsequently decreases the inflammatory activation measured by FDG uptake and serum biomarkers.

Cardiac SarcoidosisWhat 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.
Evaluating Airway Sarcoidosis Pathology With MRI
SarcoidosisSarcoidosis 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.

Healthy SubjectsRheumatoid Arthritis2 moreThis 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.
Evaluation of the Prognostic Value of PET/MRI in Cardiac Sarcoidosis
Cardiac SarcoidosisCardiac damage is the main cause of death in patients with sarcoidosis, after pulmonary damage. Today's challenge is to diagnose the disease as effectively as possible, and to develop tools for better risk stratification, especially for sudden death, in order to better target therapies and implantable devices, such as corticoids and immunosuppressant. The hypothesis is that combined PET (Positron Emission Tomography)/MRI (Magnetic Resonance Imaging) could be a relevant prognostic marker of progression, and would significantly improve diagnostic performance in patients with suspected cardiac sarcoidosis (CS). This study will also make it possible to distinguish sequellar fibrosis lesions from granulomatous lesions and assess the therapeutic response. Incorporating PET/MRI into the diagnostic strategy for patients with suspected CS could therefore improve their management.
University of Virginia Natural History Study
Interstitial Lung DiseaseIdiopathic Pulmonary Fibrosis4 moreData and specimens will be collected longitudinally from patients seen in the UVA Interstitial Lung Disease (ILD) clinic in order to describe the phenotypic expression of various interstitial lung diseases. Samples will also be collected from a control group for comparison purposes. All data will be entered into a repository for future research purposes or screening for new studies that become available. This data will help identify trends and hopefully lead to a better understanding of the disease progression, treatment options, and outcomes.
Sahlgrenska Cardiomyopathy Project
Dilated CardiomyopathiesHypertrophic Cardiomyopathy6 moreThis is a joint project by Sahlgrenska University Hospital: Sahlgrenska, Östra and Mölndal. Our objective is to diagnose and map patients with well phenotyped cardiomyopathies (CMP) including in depth clinical and molecular phenotyping to enable earlier and specific treatment. The project will serve as: resource for diagnostic and therapeutic trials common biomaterial bank resource for detailed molecular analyses on patients' biomaterials and patient specific symptoms and examination results
Medication Adherence in Patients With Sarcoidosis
Medication AdherenceSarcoidosisThe goal of the study is to look at the relationship between how individuals with Sarcoidosis take the sarcoidosis medicines and how it affects the disease, to evaluate any factors that may make individuals not want to take the medicines, and to develop and refine ways to help support individuals with Sarcoidosis especially when it comes to the medicines. The overall hypothesis is higher medication adherence will be associated with better clinical outcomes in sarcoidosis. The investigators will enroll 150 patients with biopsy proven pulmonary sarcoidosis for at least one year who are on any oral treatment regimen for at least six months into a 12-month longitudinal study.
Lyon Sarcoid Uveitis Cohort
Sarcoid UveitisSarcoidosis 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.
Role of Genetic Factors in the Development of Lung Disease
Cystic FibrosisPulmonary Fibrosis3 moreThis study is designed to evaluate the genetics involved in the development of lung disease by surveying genes involved in the process of breathing and examining the genes in lung cells of patients with lung disease. The study will focus on defining the distribution of abnormal genes responsible for processes directly involved in different diseases affecting the lungs of patients and healthy volunteers. Optional CT Sub-study The standard CT scan will be compared to the low dose radiation CT scan for the 150 subjects enrolled in the sub-study to assess the variation between the two techniques. Specifically, the quantitative computer aided detection of lung CT abnormalities from LAM can be compared to assess whether low radiation dose CT exams is an alternative to conventional CT to monitor disease status. This optional sub-study will be offered to up to 100 adult subjects with lung disease and up to 50 children age 9 and older with CF. Children will not be enrolled in the optional CT sub-study unless they have had a standard CT scan for medical purposes to use in comparison. One additional low dose radiation CT scan of the chest may be done as part of this sub-study when these subjects have their next annual CT scan.
