European/International FMD Registry and Initiative

Fibromuscular Dysplasia

The main objectives of FEIRI are: (i) To describe the demographic and arterial characteristics of FMD and related diseases at a global scale and according to countries and/or ethnic origin (ii) To evaluate the incidence and predictors of novel FMD lesions and complications (iii) To explore the commonalities and differences between FMD, SCAD and so-called atypical FMD (patients with multiple dissections and/or aneurysms without string-of-beads, focal stenosis or evidence of inherited arteriopathy) (iv) To contribute to the unravelling of genetic, proteomic and molecular mechanisms underlying FMD and related diseases Participation to the FEIRI study implies: (i) Collection of demographic and standard-of-care clinical data, both retrospectively (from the diagnosis of FMD to signature of the informed consent) and prospectively (on the occasion of standard-of-care follow-up). (ii) Optional participation to a biobank implying collection of blood, urine and, in rare cases of intervention, tissue samples for genomic and proteomic analysis and identification of diagnostic and prognostic biomarkers of FMD. Participants will be enrolled in centres from over 20 countries in Europe and beyond.

National Registry of Rare Kidney Diseases

Adenine Phosphoribosyltransferase DeficiencyAH Amyloidosis85 more

The goal of this National Registry is to is to collect information from patients with rare kidney diseases, so that it that can be used for research. The purpose of this research is to: Develop Clinical Guidelines for specific rare kidney diseases. These are written recommendations on how to diagnose and treat a medical condition. Audit treatments and outcomes. An audit makes checks to see if what should be done is being done and asks if it could be done better. Further the development of future treatments. Participants will be invited to participate on clinical trials and other studies. The registry has the capacity to feedback relevant information to patients and in conjunction with Patient Knows Best (Home - Patients Know Best), allows patients to provide information themselves, including their own reported quality of life and outcome measures.

Renal Artery Fibromuscular Dysplasia Registry

Renal Artery Fibromuscular Dysplasia

Study name: A Prospective Study of the Renal artery fibromuscular dysplasia Registry in China Rationale: Fibromuscular dysplasia (FMD) is an idiopathic systemic noninflammatory arterial disease resulting in narrowing of medium-sized arteries. Renal arteries are most commonly involved vessels, although it can also affect arteries in other vascular territories. Renal artery FMD is the second frequent cause of renovascular hypertension , especially in adolescents. The pathogenesis of FMD is still not understood. There were little Asians in the United States and the European/International FMD registry. Objective: 1) To describe the characteristics of renal artery FMD; 2) To identify environmental/ hormonal factors and exposures (for example smoking) associated with the onset and progression of renal artery FMD; 3)To identify baseline characteristics of the disease associated with an increased risk of complications such as dissections, aneurysms, stroke or myocardial infarction; 4) To provide evidence-based algorithms for the management and follow-up of patients with renal artery FMD; 5) To establish a comprehensive imaging resource including a wide range of presentations of renal artery FMD. Study design: Prospective, multi-center, observational study. Study population: renal artery fibromuscular dysplasia Data Collections: 1) Data on demographic characteristics, clinical characteristics, blood routine, biochemical and plasmic electrolytes and vascular imaging were collected using a questionnaire; 2) The diagnosis of renal artery FMD was based on the identification of focal or multifocal FMD lesions in at least one arterial bed by computed tomography angiography, magnetic resonance angiography and/or digital subtraction angiographies; 3) For the patients with renal artery FMD, screening was performed to assess most arteries and multivessel FMD would be collected; 4) All patients would be followed up. Treatment: Standardized diagnosis and treatment procedure as recommended in the International Consensus on the diagnosis and management of fibromuscular dysplasia. Follow up: 3, 6, 12 months after diagnosis and every year after enrolled. Sample size estimation: About 5 hundred. Timeline: Start of subjects' enrollment: Jan 2021; End of subjects enrollment: December 2026; End of study: December 2036. Organization: The Centre for Epidemiological Studies and Clinical Trials, Ruijin Hospital, Shanghai, China.

Defining the Basis of Fibromuscular Dysplasia (FMD)

Fibromuscular DysplasiaSpontaneous Coronary Artery Dissection1 more

The purpose of this study has evolved and expanded since its inception. Originally the intent was to establish the functional, molecular and genetic profile of fibroblasts from Fibromuscular Dysplasia (FMD) patients as compared to carefully matched control subjects. While this remains among the objectives, the study has been expanded to undertake a fully powered cross-tissue systems genetics analysis of FMD, and now also the related arteriopathies spontaneous coronary artery dissection (SCAD) and cervical artery dissection (CvAD). The overall objective is to disclose the core biologic mechanisms of these disorders.

Assessment of Renal Artery Fibromuscular Dysplasia: From Diagnosis to Treatment

Renal Artery Fibromuscular Dysplasia

This is a prospective multicenter study based on the validation of diagnostic criteria and predictive factors of treatment efficacy for renal artery stenosis in renal artery dysplasia. This is considered as a rare disease and patients are usually treated in specialized centers involved in a national network. Marseille is a center specialized in FMD and a member of the network that is very active across the country. In order to rapidly recruit patients the investigators propose a multicenter study. All patients included will benefit from an invasive angiography with trans stenotic gradient assessment at rest. In case of bilateral stenosis the investigators will randomly omit data from one side and consider the data from the contralateral artery for further analysis, to avoid statistical interdependency. Patients who require angioplasty and who have unilateral stenosis (unilateral FMD lesion or bilateral but with one non significant stenosis based on duplex ultrasound European recommendations for atherosclerotic renal artery stenosis) will be included in the second part of the study. These patients will in addition benefit from a trans stenotic pressure assessment under vasodilation and intravascular renal artery ultrasound. Patients with severe bilateral renal artery stenosis will not be included in the analysis to assess predictive criteria for treatment efficacy on hypertension, treatment of these patients will followed the current best clinical practice. These patients will be followed during 6 to 8 month to assess potential complication of the pressure assessment renal artery stenosis, but their data will be included to assess the value of FFR and IVUS to guide the procedure. Patients with unilateral stenosis will be followed up 6 month after angioplasty in order to assess hypertension and to look for potential complications.

The Study of the Prevalence Fibromuscular Dysplasia in Patient With Haematoma or Spontaneous Coronary...

Spontaneous Coronary Artery DissectionSpontaneous Coronary Artery Haematoma

Spontaneous Coronary Artery Dissection (SCAD) is a rare and often misdiagnosed cause of Acute Coronary Syndrome (ACS) affecting predominantly young women without cardiovascular risk factors. The origin of SCAD remains uncertain but a strong and frequent association with Fibromuscular Dysplasia (FMD) has been recently reported based on imaging evidence only. The aim of our study is to assess the presence of FMD and its genetic determinants i in a sample for haematoma or spontaneous coronary artery dissection. From May 2016 to 2018 we plan to include prospectively and retrospectively 200 patients admitted for ACS with confirmed diagnosis of SCAD. This study will be conducted in more than 30 French interventional cardiology centers. Coronary angiograms or intracoronary imaging data will be reviewed by two experienced interventional cardiologist experts in SCAD diagnosis. For each patient a genetic analysis will be performed. A systematic screening for FMD will be realized by computed tomographic or MRI angiography of renal, cerebrovascular and iliac arteries and reviewed by two experienced radiologists. A one year follow-up is expected. This study aims to confirm the presumed association of FMD and SCAD through the exploration of several artery beds and the study of confirmed genetic determinants, which has never been described previously to our knowledge.
