The overall objective of this study is to investigate Fabry-associated renal organ involvement by using a novel magnetic resonance imaging (MRI) approach, focusing on changes in renal oxygen levels by blood oxygenation-level dependent (BOLD) imaging. Furthermore, to correlate renal oxygenation to the phenotypic presentation of patients with Fabry-associated nephropathy regarding circulating and imaging-derived biomarkers of kidney inflammation, fibrosis and injury as compared with healthy age- and sex-matched controls. The study will achieve this by: 1) Using a non-invasive, contrast-free MRI protocol focusing on parameters of oxygenation, inflammation, fibrosis, and injury in the kidney. 2) Using an extensive, in-depth biomarker blood panel to investigate the pathological pathways associated with Fabry disease and Fabry-associated nephropathy.
This is an open-label multi-center study to evaluate safety and biomarkers of efficacy of a single dose of intravenously-administered AMT-191. The study will also include exploratory functional efficacy assessments. The plan is to investigate 2 sequential dose cohorts in 3-6 Participants per cohort. Participants will be monitored for 24 hours following AMT-191 administration then follow-up study visits will continue for 24 months, during which safety, pharmacokinetics/pharmacodynamics, biomarkers, and efficacy assessments will be performed. Participants will continue receiving their regularly scheduled enzyme replacement therapy (ERT) until they meet the criteria for withdrawal.
This is a single-arm, open label, single-dose clinical study to evaluate the safety, tolerability and efficacy of BBM-F101 injection in the pediatric Fabry disease participants up to 52 weeks after infusion, and the long-term safety and efficacy of BBM-F101 injection up to 5 years after infusion. BBM-F101 injection is an adeno-associated virus (AAV) gene therapy product for the treatment of pediatric Fabry disease.
The goal of this clinical trial is to test dapagliflizone in Fabry patients. The main questions it aims to answer are: - Has 10 mg/d of dapagliflozin a positive effect on kidney functions of Fabry patients. - Has 10 mg/d of dapagliflozin a positive effect on heart functions in Fabry patients. Participants will be asked to - Sign an informed consent - Give a blood and urine samples - Be subjected to Echocardiography investigation - Take 10 mg/day Dapagliflizone Researchers will compare treatment to placebo groups to see if kidneys and heart functions will be improved in the treatment group better more than the placebo group.
The main objective is to assess the occurrence of cardiac arrhythmias and conduction disorders during a three-year follow-up using implantable Holter ECG monitoring in 40 patients with Fabry disease. The secondary objectives are to analyze the correlations of these anomalies with changes in cardiac MRI and echocardiographic parameters as biological parameters and overall severity of the disease assessed by MSSI.
In vivo confocal microscopy (IVCM) has been used in clinical settings for more than 25 years, and is noninvasive, rapid and easily repeatable technique to investigate ocular surface disorders. It enables morphological and quantitative analysis of ocular surface microstructure. [1-3] As the technology advances, new IVCM machine, Heidelberg Retinal Tomograph with Rostock Corneal Module (HRT-RCM), was developed. Hardware and software modifications and acquisition techniques continue to expand the applications of the HRT-RCM for quantitative in vivo corneal imaging at the cellular level. The new software can access the corneal nerve more accurate. Here the investigators proposed this Institutional Review Board (IRB) to collect healthy persons and cases of different systematic diseases as well as etiologies of ocular surface diseases.
Cardiac complications occur in 78% of patients with Fabry disease and are mainly characterized by a high frequency of left ventricular hypertrophy resulting from an accumulation of GL3 in cardiomyocytes. Apart from family screening, left ventricular hypertrophy is an important factor in the diagnosis of Fabry disease. This left ventricular hypertrophy is more often concentric and homogeneous, but it can also be asymmetric and mimic the patterns seen in so-called familial hypertrophic cardiomyopathies caused by mutations in the sarcomere protein genes. Electrocardiogram has been suggested as a screening tool for Fabry disease. Analysis of the PQ interval would be of interest. An algorithm has even been proposed to differentiate Fabry disease from amyloidosis with excellent sensitivity and specificity. The only criterion of left ventricular hypertrophy used in all studies is the Sokolov-Lyon index, but this index has many limitations and does not appear to be discriminatory for Fabry disease. Other validated criteria for left ventricular hypertrophy, such as the Cornell, Lewis, Gubner index or the Romhilt-Estes point score, have never been tested in Fabry disease. The primary objective of our study is to evaluate the diagnostic value of different electrocardiographic scores of left ventricular hypertrophy in Fabry disease.
Fabry disease is caused by the deficiency or absence of alpha-galactosidase A (α-Gal A) activity, leading to progressive deposition of glycosphingolipids, mainly globotriaosylceramide (Gb3), in the lysosomes of multiple tissues and organs. In Taiwan, Dr. Niu first revealed a surprisingly high incidence (approximately one in 1,600 males) of a cardiac variant GLA splicing mutation, IVS4+919G>A, in newborn screening. Patients who carried the IVS4 + 919G > A mutation and were older than 40 years had a higher prevalence of hypertrophic cardiomyopathy. Endocardial biopsy of these patients with hypertrophic cardiomyopathy showed significant Gb3 accumulation in the cardiomyocytes. Although the hotspot IVS4+919G>A mutation is now being observed with greater frequency, understanding of the natural course of cardiac variant Fabry disease with this specific mutation remains limited. Therefore, our study would like to conduct a study to approach the natural history among patients with Chinese hotspot late-onset Fabry mutation IVS4+919G>A through family pedigree analysis.
The cardiac variant of the Fabry disease is a rare cardiomyopathy affecting 1/50000 individuals in general population. It is generally diagnosed in advanced stages of the disease, because it presents clinical features very similar to the hypertrophic cardiomyopathy ones, making difficult the correct diagnosis. In Fabry disease there is a remodeling process of the myocardial interstitium and apoptosis of myocytes which leads to fibrosis development and later systolic dysfunction. The investigators propose to evaluate the utility of several biomarkers in the diagnosis of this cardiomyopathy, to facilitate the early diagnosis, which is clue to establish early enzyme replacement therapy or intensify the patients' follow up. In order to achieve this objective, the investigators will analyze markers of endothelial dysfunction, fibrosis and apoptosis in peripheral blood samples of patients carrying the mutation but without clinical manifestations and the investigators will compare their levels with dose obtained from two different control groups: diagnosed patients presenting clinical manifestations or index cases and healthy controls without carrying the mutation.
