Summary: To evaluate the safety of [64Cu] Macrin and its whole-body distribution, metabolism, pharmacokinetics, and radiation burden in healthy volunteers. To detect [64Cu]-Macrin accumulation in sites of disease in subjects with cancer, sarcoidosis or myocardial infarct.

Summary: Neurosarcoidosis represents up to 10% of sarcoidosis cases. Little is known about its long-term course, even if the disease remains mainly monophasic with/w.o. sequelae, or if bouts of new symptoms may arise over years (polyphasic).Using retrospective data from patients diagnosed with neurosarcoidosis in three French referral centers for neuro-inflammation, the investigators aim to determine patte...

Summary: Strain elastography (SE) is an imaging method used for the measurement of relative tissue elasticity through qualitative (color pattern) or semi-quantitative methods (strain ratio or strain histogram). Very recently, the first pilot study has provided preliminary evidence that EBUS-SE elastography may help identify fibrotic lymph nodes in sarcoidosis and that sampling lymph nodes characterized by ...

Summary: The presence of calcifications, which is a relatively common feature in intrathoracic lymph nodes, typically contributes to confer them a heterogeneous aspect during endosonographic B-mode examination, but their prevalence and a possible association between calcifications and metastatic involvement has never been systematically evaluated. We hypothesize that in patients undergoing mediastinal diag...

Summary: In the last few years, high-definition (HD) videobronchoscopy has become widely available in the market and will progressively become the standard of care for airway inspection and sampling, as it provides substantially higher resolution images as compared to conventional white light bronchoscopy. Furthermore, in combination with improved video processor units, some HD videobronchoscopes offer pos...

Summary: Recent studies suggest that the JAK/STAT signaling pathway constitutes a new step in the clinical and therapeutic progress of sarcoidosis. Further investigations are necessary to identify the most suitable patients to receive treatment targeting this pathway, in particular in cases of severe sarcoidosis refractory to the various therapeutic lines.

Summary: Sarcoidosis is an idiopathic disorder characterized by granulomatous inflammation involving various organ systems. The lung and mediastinal lymph nodes are the most commonly involved structures in sarcoidosis. In the presence of intrathoracic lymph nodes, transbronchial needle aspiration (TBNA) is a useful diagnostic modality, which is now guided using endobronchial ultrasound (EBUS).We hypothesiz...

Summary: Oral selexipag is commercially available in several countries for the treatment of a particular group of pulmonary hypertension (PH) called pulmonary arterial hypertension (PAH). The aim of the present study is to investigate whether selexipag could be helpful to treat patients with another form of PH called sarcoidosis-associated pulmonary hypertension (SAPH).

Summary: In industrialized countries, it is estimated that around 10% of the population suffers from nephrolithiasis (NL). Numerous recent epidemiological studies report that the prevalence and incidence of NL continue to increase, with a prevalence that has nearly doubled over the past two decades. A patient who presented with a first episode of renal lithiasis has an estimated recurrence rate of nearly 5...

Summary: The treatment of chronic inflammatory skin diseases is a difficult point in clinical diseases, which mainly include patients with pathological scars, sarcoidosis and chronic eczema. Chronic nodular lesions and long-term itching symptoms bring great physical and mental pain to patients.Long-term repeated treatments are required. At present, the most commonly used treatment is intralesional injectio...

Summary: The main objective of this part of the project is to identify the germline genetic factors which discriminate the benign and severe forms of SARS-CoV2 (CoVID-19) infection in the context of the ongoing SARS-CoV2 (HCOVID-19) epidemic. The scientific arguments of the project are described in APPENDIX. We hypothesize that pathogenic variants in genes coding for crucial factors involved in the HOST PA...

Summary: Sarcoidosis is a heterogeneous disorder of unknown etiology whose signature lesions are granulomatous inflammatory infiltrates in involved tissues. Tissue commonly affected are lungs, skin, eyes, lymph nodes and the heart. In this latter case, cardiac sarcoidosis (CS) can lead to atrioventricular (AV) blocks, ventricular arrhythmias, heart failure (HF) and sudden cardiac death. Similar to other in...
