Arrhythmia Burden, Risk of Sudden Cardiac Death and Stroke in Patients With Fabry Disease
Fabry DiseaseFabry disease (FD) is a genetic disorder that leads to progressive accumulation of fat or 'sphingolipid' within the tissues, including the heart muscle and conductive tissue. Improvements in the detection of FD, together with more organised clinical services for rare diseases, has led to a rapid growth in the disease prevalence. Earlier and more frequent diagnosis of asymptomatic individuals before development of the disease itself has focused attention on early detection of organ involvement and closer monitoring of disease progression. Moreover, the introduction of enzyme replacement therapy within the last two decades has changed the natural history of FD as follows: a) increased life expectancy; b) improved morbidity; c) modification of the main cause of morbidity and mortality from renal (kidney) to cardiovascular (heart) events, including heart failure, abnormal heart rhythms, stroke and sudden death. Although symptoms such as palpitations and blackouts are extremely common, information on the frequency of proven abnormal heart rhythms is limited. In addition, the rate and appropriateness of implantation of life-saving devices is very variable, including pacemakers to boost the heart when too slow and cardio-defibrillators that stop the heart when too fast. The main markers of risk in similar diseases such as hypertrophic cardiomyopathy cannot be used in FD. While patients are routinely followed up in clinic with heart tracings and echocardiography (ultrasound of the heart), a recent small study has emphasised that these tests under-estimate the burden of abnormal heart rhythms in patients with advanced FD. The use of continuous heart monitoring with an implantable loop recorder (ILR) has led to a significant change in treatment in 13 out of 15 of FD patients. The investigators believe that more frequent use of ILRs will identify a greater need for change in therapy in many more patients than currently treated, with the aim of reducing morbidity and mortality in this patient cohort. In addition this will provide valuable data to inform an estimate of future risk for these patients.
Evaluation of a Screening Strategy of Fabry Disease in Patient With Renal Biopsy
Renal DiseaseFabry disease is genetic X linked disease, with annual incidence of 1 in 100,000 that is certainly underestimate the true prevalence of the disease. Renal biopsy in some patients does not allow determining the etiology of nephropathy. It is why investigators would like to evaluate the screening of Fabry patients from renal biopsy in patient with idiopathic nephropathy. Investigator hypothesize to detect one or more cases of patients with Fabry disease in local idiopathic nephropathy population with renal biopsy. That would allow reviewing and optimizing the target screening for Fabry Disease. The purpose would be to detect Fabry disease systematically in patients presenting a nephropathy of undetermined etiology in spite of the renal biopsy or presenting nonspecific histological characteristics. In Fabry disease with renal impairment, proteinuria is the first sign, usually occurring in the second decade. The evolution is progressively towards end-stage renal failure during the fourth decade. The presence of renal impairment is globally associated with a poor prognosis. Renal histology can be used to diagnose Fabry disease by revealing sphingolipid deposits identified by optical microscopy in the form of vacuoles in podocytes, distal tubule epithelial cells or in the media of the distal tubules. vascular walls. Resin inclusion with Toluidine blue staining is the staining of choice for visualizing lipid inclusions. However, this staining is not used as a first intention in routine. On the paraffin-fixed tissues, the vacuoles are less visible because they dissolve. Thus, the renal histological analysis sometimes reveals only non-specific damage to the various structures of the kidney and may not allow identification of very evocative inclusions. Under the effect of oxidative stress induced by sphingolipid deposits, lesions of tubulo-interstitial fibrosis settle quite early. At the level of the glomerulus, glycosphingolipids lead to the production of angiotensin II and TGF-β leading to an excess production of constituents of the glomerular basement membrane inducing its thickening and glomerulosclerosis. Arteries of all sizes are also the seat of intimal thickening and media accelerating the process of intrarenal ischemia. These lesions, which may appear isolated or synchronous, and nonspecific, are sometimes in the foreground and do not point in the first line to the etiological diagnosis of Fabry disease. Also, among the patients presenting a nephropathy of undetermined etiology in spite of the renal biopsy or presenting nonspecific histological characteristics, investigator propose to systematically detect the Fabry disease. Screening will be done in a selected population of renal biopsy patients using the dried blood spot kits.
