NCT06220526
This randomized pilot clinical trial aims to examine whether sample collection with Franseen-type needles are effective for the diagnosis of sarcoidosis, as defined by improved sample quality for pathological diagnosis compared to the conventional Menghini-type needle.
NCT07073963
This research study is testing whether Mindfulness-Based Stress Reduction (MBSR) can help reduce fatigue in people with sarcoidosis. The study will also look at whether MBSR can improve symptoms of anxiety and depression. Participants will be placed into one of two groups: * One group will take part in an 8-week virtual MBSR program, attend weekly online sessions, keep a daily mindfulness journal, and complete surveys about fatigue, anxiety, and depression. * The other group will join a virtual support group once a month for 5 months and complete the same surveys. The goal is to see which approach is more helpful for improving fatigue and mental well-being in people with sarcoidosis.
NCT05746039
The goal of this clinical trial is to learn whether semaglutide, an FDA-approved treatment for diabetes and obesity, is feasible and tolerable in patients with advanced lung disease. The main question\[s\] it aims to answer are: 1. Are patients with advanced lung disease able to tolerate semaglutide therapy? 2. Are we able to titrate semaglutide therapy to a target weight? Participants will be asked to perform pulmonary function, physical function and body composition testing, as well as a blood draw before and after 12-weeks of semaglutide therapy. While on therapy, subjects will be surveyed regarding any adverse events or side effects.
NCT04402086
To facilitate clinical, basic science, and translational research projects involving the study of rheumatic diseases.
NCT05291468
In 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.
NCT03814317
This study aims to evaluate the efficacy and safety of inhaled treprostinil in subjects with sarcoidosis-associated interstitial lung disease and pulmonary hypertension.
NCT07246876
Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), combined with endobronchial biopsy (EBB) and/or transbronchial lung biopsy (TBLB), and endobronchial ultrasound-guided transbronchial mediastinal cryobiopsy (EBUS-TBMC) have high diagnostic yields for patients with sarcoidosis. However, a direct comparison between them has not been conducted. This randomized controlled trial aims to compare directly the diagnostic yield between EBUS-TBMC and EBUS-TBNA+EBB+TBLB in sarcoidosis.
NCT07359690
The goal of this observational study is to pursue a multimodal approach to identify the molecular signatures and immune signalling molecules of various myocardial diseases and thereby contribute to improving diagnosis and therapy. The main aim is: -Identification of molecular profiles (e.g., proteome, lipidome, metabolome) and immune signalling profiles that are specifically associated with different myocardial diseases and the post-heart transplantation course. Participants already receiving an endomyocardial biopsy as part of their regular medical care will be enrolled. An additional biopsy sample will be taken for the above mentioned research.
NCT06573723
The goal of this observational study is to create a single macro registry system with data collection on common clinical features, grouping the different rare diseases (RD). Moreover, the specific goals are to generate an alert system for possible cases of RD with data from the electronic medical record, to describe the occurrence of RD in the evaluated population, to characterize the population, to describe patterns of diagnosis and treatment of RD present at the time, and to explore patient-reported outcomes.
NCT06510894
This is a pilot mechanistic study of the diagnostic utility of sodium-glucose cotransporter-1/2 inhibition (SGLT1/2) on myocardial glucose suppression on FDG PET/CT. The investigators will test whether the addition of a SGLT1/2 inhibitor (SGLT1/2i) plus the standard dietary modification (ketogenic diet) will provide enhanced myocardial glucose suppression. The primary objective is to assess rates of complete myocardial glucose suppression (MGS) with 7 days of sotagliflozin 400 mg QD among healthy volunteers on a background of 1 day (N=20) or 3 days (N=20) of the KD. The secondary goal is to investigate the relationship between sotagliflozin, targeted metabolite levels, and myocardial glucose utilization on FDG-PET. Participants will be asked to: * undergo a screening visit that includes blood tests, vitals, and questions regarding health history/medications * take the provided sotagliflozin as instructed for 7 days leading up to the scan * follow a ketogenic diet as instructed for 1 or 3 days leading up to the scan * undergo an FDG PET/CT scan, which includes vitals and blood draws
NCT03621553
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.
NCT05438095
The 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.
NCT02134717
The study hypothesizes that inhibition of the receptor CCR5 by maraviroc will diminish inflammation in patients with sarcoidosis. Subjects with active sarcoidosis will first undergo bronchoscopy with bronchoalveolar lavage to recover lung immune cells for baseline analysis. They will then receive the drug maraviroc for 6 weeks duration. They will then undergo a repeat bronchoscopy with bronchoalveolar lavage to recover lung immune cells for analysis following maraviroc treatment.
NCT05841758
Sarcoidosis is a systemic granulomatous disease of unknown aetiology, mainly affecting the lungs and lymphatics. It affects people worldwide (incidence, 4.7-64/100000; prevalence, 1-36/100000/year). Although it is most often a benign acute or subacute condition, sarcoidosis may progress to a disabling chronic disease in 25% of the cases, with severe complications in about 5%, such as lung fibrosis, cardiac or neurosarcoidosis, defacing lupus pernio or blindness due to uveitis. When indicated, corticosteroids (CS) are the mainstay of treatment. Due to the kinetics of granuloma resolution, the usual and quite 'dogmatic' duration of treatment is said to be one year, following four classical steps. The long-term use of CS is hindered by cumulative toxicity and efforts have to be made to taper them, as quickly as possible, to the lowest effective dose. A recent report mentioned 39% of the CS-treated patients requiring a steroid-sparing agent. Chloroquine (CQ) and hydroxychloroquine (HCQ) are anti-malarial drugs that have been used since the 1960's as steroidsparing agents on the basis of a landmark study by Siltzbach reporting their efficacy in 43 patients with skin and intrathoracic sarcoidosis. Subsequently, two small randomized controlled trials have shown significant and prolonged improvement on pulmonary symptoms. Only small case series/reports have shown CQ/HCQ efficacy on extra-pulmonary sarcoidosis with response rates ranging from 67 to 100%. Nevertheless, CQ/HCQ are daily used for skin, bone, and joint sarcoidosis, as well as hypercalcemia. Nowadays, HCQ is preferred over CQ because of a lower incidence of gastrointestinal and ocular adverse reactions, which can be minimized by close attention to the dosage and regular retinal examination. Its profile of safety is well-known since it has long been employed to treat systemic lupus erythematous or rheumatoid arthritis. Its action is thought to rely on its ability to accumulate in lysosomes of phagocytic cells, to affect antigen presentation and reduce pro-inflammatory cytokines. The investigator hypothesize that HCQ may be an efficacious add-on therapy for extra-pulmonary sarcoidosis leading to a significant steroid-sparing effect.
