Clinically Meaningful Outcomes after 1 Year of Treatment with Setmelanotide in an Adult Patient with a Variant in SH2B1.

Introduction: Monogenic obesity is caused by a unique genetic dysfunction, often appears in childhood, and can be accompanied by neuroendocrine, skeletal, developmental, and behavioral disorders, among other manifestations. Some variants in the SH2B1 gene have been suggested as strong candidates for the development of autosomal dominant obesity.

Case Presentation: We describe here the clinical response after 1 year of setmelanotide treatment in a 22-year-old patient with an SH2B1 variant.

Global reach of over 20 years of experience in the patient-centered Fabry Registry: Advancement of Fabry disease expertise and dissemination of real-world evidence to the Fabry community.

Fabry disease (FD, α-galactosidase A deficiency) is a rare, progressive, complex lysosomal storage disorder affecting multiple organ systems with a diverse spectrum of clinical phenotypes, particularly among female patients. Knowledge of its clinical course was still limited in 2001 when FD-specific therapies first became available and the Fabry Registry (NCT00196742; sponsor: Sanofi) was initiated as a global observational study. The Fabry Registry has now been operational for over 20 years, overseen by expert Boards of Advisors, and has collected real-world demographic and longitudinal clinical data from more than 8000 individuals with FD.

Fabry disease and COVID-19: international expert recommendations for management based on real-world experience.

The rapid spread of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 has raised questions about Fabry disease (FD) as an independent risk factor for severe COVID-19 symptoms. Available real-world data on 22 patients from an international group of healthcare providers reveals that most patients with FD experience mild-to-moderate COVID-19 symptoms with an additional complication of Fabry pain crises and transient worsening of kidney function in some cases; however, two patients over the age of 55 years with renal or cardiac disease experienced critical COVID-19 complications. These outcomes support the theory that pre-existent tissue injury and inflammation may predispose patients with more advanced FD to a more severe course of COVID-19, while less advanced FD patients do not appear to be more susceptible than the general population.

The clinical profiles of female patients with Fabry disease in Latin America: A Fabry Registry analysis of natural history data from 169 patients based on enzyme replacement therapy status.

Background: Fabry disease is an X-linked lysosomal storage disorder with heterogeneous clinical expression in female patients ranging from asymptomatic to severe clinical presentations as in classic males. We assessed clinical profiles and compared natural history data of female patients eventually initiated on enzyme replacement therapy ("ERT-recipients") with those remaining untreated ("ERT-naïve").

Methods: We analyzed Fabry Registry data from 93 ERT-recipients, collected prior to ERT initiation, and 76 ERT-naïve females with classic or unclassified phenotypes from four Latin American countries and evaluated Fabry symptoms, interventricular septum thickness, left ventricular posterior wall thickness, estimated glomerular filtration rate, and severe clinical events.

Enabling Global Clinical Collaborations on Identifiable Patient Data: The Minerva Initiative.

The clinical utility of computational phenotyping for both genetic and rare diseases is increasingly appreciated; however, its true potential is yet to be fully realized. Alongside the growing clinical and research availability of sequencing technologies, precise deep and scalable phenotyping is required to serve unmet need in genetic and rare diseases. To improve the lives of individuals affected with rare diseases through deep phenotyping, global big data interrogation is necessary to aid our understanding of disease biology, assist diagnosis, and develop targeted treatment strategies.

Altered globotriaosylceramide accumulation and mucosal neuronal fiber density in the colon of the Fabry disease mouse model.

Background: Fabry disease (FD) is a hereditary X-linked metabolic storage disorder characterized by deficient or absent lysosomal α-galactosidase A (α-Gal A) activity. This deficiency causes progressive accumulation of glycosphingolipids, primarily globotriaosylceramide (Gb3), in nearly all organ systems. Gastrointestinal (GI) symptoms can be very debilitating and are among the most frequent and earliest of the disease.

Recommendations for Evaluation and Management of Pain in Patients With Mucopolysaccharidosis in Latin America.

The mucopolysaccharidosis (MPS) constitutes a heterogeneous group of rare genetic disorders caused by enzymatic deficiencies that lead to the accumulation of glycosaminoglycans. Several types of MPS are described, historically numbered from I to IX. Clinical observations strongly suggest the presence of chronic pain in patients with all types of MPS.

Fabry disease: Four case reports of meningioma and a review of the literature on other malignancies.

Fabry disease (FD) is an X-linked lysosomal storage disorder caused by loss of function mutations in the gene at Xq22 with subsequent functional deficiency of alpha-galactosidase A, resulting in the accumulation of globotriaosylceramide (GL-3 or Gb) in multiple cells types throughout the body. As with other rare metabolic disorders, little is known about the incidence of malignancies in these populations and the relationship to the underlying disease, if any. We report the occurrence of meningioma in four female patients with Fabry disease.

Familial gain-of-function Na1.9 mutation in a painful channelopathy.

Objective: Gain-of-function mutations in Na1.9 have been identified in three families with rare heritable pain disorders, and in patients with painful small-fibre neuropathy. Identification and functional assessment of new Na1.

Pain in Fabry Disease: Practical Recommendations for Diagnosis and Treatment.

Aims: Patients with Fabry disease (FD) characteristically develop peripheral neuropathy at an early age, with pain being a crucial symptom of underlying pathology. However, the diagnosis of pain is challenging due to the heterogeneous and nonspecific symptoms. Practical guidance on the diagnosis and management of pain in FD is needed.

Determinants of white matter hyperintensity burden in patients with Fabry disease.

Objective: Using a semiautomated volumetric MRI assessment method, we aimed to identify determinants of white matter hyperintensity (WMH) burden in patients with Fabry disease (FD).

Methods: Patients with confirmed FD and brain MRI available for this analysis were eligible for this protocol after written consent. Clinical characteristics were abstracted from medical records.

Foot process effacement is an early marker of nephropathy in young classic Fabry patients without albuminuria.

Unlabelled: In Fabry disease, globotriaocylceramid (GL3) starts to accumulate in kidney cells in utero, and continues to accumulate throughout childhood and adulthood with progressive tissue damage, which may lead to renal failure.

Material And Methods: Eight children with classical Fabry disease, median age 12 (range 4-16 years) had a renal biopsy performed before the initiation of enzyme replacement therapy (ERT). All patients were normalbuminuric and had normal GFR.

Histologic abnormalities of placental tissues in Fabry disease: a case report and review of the literature.

Fabry disease is an X-linked lysosomal storage disease caused by deficiency of α-galactosidase A, resulting in the accumulation of globotriaosylceramide. Many women experience symptoms, but the understanding of placental and fetal aspects of the disease is limited. We report the pregnancy outcome in and placental pathology of a 37-year-old woman with Fabry disease.

Early diagnosis of peripheral nervous system involvement in Fabry disease and treatment of neuropathic pain: the report of an expert panel.

Background: Fabry disease is an inherited metabolic disorder characterized by progressive lysosomal accumulation of lipids in a variety of cell types, including neural cells. Small, unmyelinated nerve fibers are particularly affected and small fiber peripheral neuropathy often clinically manifests at young age. Peripheral pain can be chronic and/or occur as provoked attacks of excruciating pain.

[Update on the treatment of Fabry's disease: pathophysiological concepts].

Introduction: Fabry's disease is a consequence of the deficiency of lysosomal alpha-galactosidase A, which gives rise to excessive depositing of glycosphingolipids in endothelial cells, smooth muscle cells in vessels, podocytes, neurons, etc. The symptoms begin in childhood, with neuropathic pain, and progress towards kidney and heart failure, as well as cerebro-vascular accidents from the third decade of life onwards.

Development: This review presents the changes in the pathophysiological concepts that have been acquired in the nine years since enzyme replacement therapy started to be employed.

Treatment with agalsidase beta during pregnancy in Fabry disease.

Fabry disease is an X-linked lysosomal storage disease caused by a deficiency of alpha-galactosidase A, which leads to excessive accumulation of glycosphingolipids in most tissues in the body, with life-threatening clinical consequences in the kidney, heart, and cerebrovascular system. Enzyme replacement therapy using exogenously produced alpha-galactosidase has been available for treatment of this multisystem progressive disease since 2001. Two different preparations of enzyme replacement therapy for Fabry disease are available outside of the USA: agalsidase alfa and agalsidase beta.

[Utility of enzyme replacement therapy in Fabry disease].

Background And Objective: The lysosomal deposit of sphingolipids secondary to alpha-galactosidase-A deficiency causes Fabry disease. The deposit in the endothelial cells of the vasa nervorum and the small caliber axons, among other structures, results in the characteristic painful neuropathy. It is our objective to present the findings of the neuropathy evaluation before and after 18 months of agalsidase beta enzyme replacement therapy.

[Stroke in Fabry disease. More than a simple stenosis].

The objective is to analyze the updated evidence on the physiopathological mechanisms that can generate cerebrovascular damage in Fabry disease. Fabry disease is the result of the deficiency of alpha-galactosidasa A, which causes pathological storage of glycosphingolipids, in different cells. Associated to renal and cardiac insufficiency, cerebrovascular complications can derive in the death of the patients.
