Usefulness of antibody-drug conjugate as preconditioning for hematopoietic stem cell-targeted gene therapy in wild-type and Fabry disease mouse models.

BACKGROUND: Fabry disease (FD) is characterized by deficient activity of α-galactosidase A (GLA). Consequently, globotriaosylceramide (Gb3) accumulates in various organs, causing cardiac, renal, and cerebrovascular damage. Gene therapies for FD have been investigated in humans. Strong conditioning is required for hematopoietic stem cell-targeted gene therapy (HSC-GT). However, strong conditioning leads to various side effects and should be avoided. In this study, we tested antibody-based conditioning for HSC-GT in wild-type and FD model mice. METHODS: After preconditioning with an antibody-drug conjugate, HSC-GT using a lentiviral vector was performed in wild-type and Fabry model mice. In the wild-type experiment, the EGFP gene was introduced into HSCs and transplanted into preconditioned mice, and donor chimerism and EGFP expression were analyzed. In the FD mouse model, the GLA gene was introduced into HSCs and transplanted into preconditioned Fabry mice. GLA activity and Gb3 accumulation in the organs were analyzed. RESULTS: In the wild-type mouse experiment, when anti-CD45 antibody-drug conjugate was used, the percentage of donor cells at 6 months was 64.5%, and 69.6% of engrafted donor peripheral blood expressed EGFP. When anti-CD117 antibody-drug conjugate and ATG were used, the percentage of donor cells at 6 months was 80.7%, and 73.4% of engrafted donor peripheral blood expressed EGFP. Although large variations in GLA activity among mice were observed in the FD mouse experiment for both preconditioning regimens, Gb3 was significantly reduced in many organs. CONCLUSIONS: Antibody-based preconditioning may be an alternative preconditioning strategy for HSC-GT for treating FD.

Fabry-specific treatment in Australia: time to align eligibility criteria with international best practices.

BACKGROUND: Disease-specific therapy aims to improve symptoms, stabilise current disease and delay progression in patients with Fabry disease. In Australia, treatment access is subject to eligibility criteria initially established in 2004. Patients and their clinicians question why these criteria have remained unchanged despite significant progress in disease understanding. AIMS: Appraise the clinical quality of the Australian treatment access criteria. METHODS: The Fabry Australia Medical Advisory Committee (N = 6) used the Appraisal of Guidelines for REsearch and Evaluation Global Rating Scale (AGREE II GRS) to assess the clinical quality of the current treatment eligibility criteria. They reviewed the literature, developed 17 clinical statements to help guide reforms of the eligibility criteria and achieved consensus (achievement of ≥75% agreement in the range 5-7 on a 7-point Likert scale) through anonymous voting. The findings were applied to develop proposals for revised classification and treatment initiation criteria. RESULTS: The current treatment eligibility criteria underperformed on the AGREE II GRS. They are pragmatic but out-of-step with contemporary data. Consensus was achieved on all 17 proposed clinical statements. There was strong agreement to differentiate classical male Fabry patients to facilitate timelier access to Fabry-specific treatment. There was also agreement on the value of adopting relevant organ involvement criteria in classical female patients and patients with non-classical disease. CONCLUSIONS: Australian access criteria are misaligned with current clinical evidence. The clinical statements and proposed classification and initiation criteria should prompt discussions to support more equitable access to treatment and better align Australian practice with contemporary evidence and international guidelines.

Fabry Disease: Cardiac Implications and Molecular Mechanisms.

PURPOSE OF REVIEW: This review explores the interplay among metabolic dysfunction, oxidative stress, inflammation, and fibrosis in Fabry disease, focusing on their potential implications for cardiac involvement. We aim to discuss the biochemical processes that operate in parallel to sphingolipid accumulation and contribute to disease pathogenesis, emphasizing the importance of a comprehensive understanding of these processes. RECENT FINDINGS: Beyond sphingolipid accumulation, emerging studies have revealed that mitochondrial dysfunction, oxidative stress, and chronic inflammation could be significant contributors to Fabry disease and cardiac involvement. These factors promote cardiac remodeling and fibrosis and may predispose Fabry patients to conduction disturbances, ventricular arrhythmias, and heart failure. While current treatments, such as enzyme replacement therapy and pharmacological chaperones, address disease progression and symptoms, their effectiveness is limited. Our review uncovers the potential relationships among metabolic disturbances, oxidative stress, inflammation, and fibrosis in Fabry disease-related cardiac complications. Current findings suggest that beyond sphingolipid accumulation, other mechanisms may significantly contribute to disease pathogenesis. This prompts the exploration of innovative therapeutic strategies and underscores the importance of a holistic approach to understanding and managing Fabry disease.

Diet and Physical Activity in Fabry Disease: A Narrative Review.

Fabry disease (FD) is caused by mutations in the galactosidase alpha (GLA) gene which lead to the accumulation of globotriaosylceramide (Gb-3). Enzyme replacement therapy (ERT) and oral chaperone therapy are the current pharmacological treatments for this condition. However, in the literature, there is a growing emphasis on exploring non-pharmacological therapeutic strategies to improve the quality of life of patients with FD. In particular, the nutritional approach to FD has been marginally addressed in the scientific literature, although specific dietary interventions may be useful for the management of nephropathy and gastrointestinal complications, which are often present in patients with FD. Especially in cases of confirmed diagnosis of irritable bowel syndrome (IBS), a low-FODMAP diet can represent an effective approach to improving intestinal manifestations. Furthermore, it is known that some food components, such as polyphenols, may be able to modulate some pathogenetic mechanisms underlying the disease, such as inflammation and oxidative stress. Therefore, the use of healthy dietary patterns should be encouraged in this patient group. Sports practice can be useful for patients with multi-organ involvement, particularly in cardiovascular, renal, and neurological aspects. Therefore, the aim of this review is to summarize current knowledge on the role of nutrition and physical activity in FD patients.

Therapeutic Strategy for Fabry Disease by Intravenous Administration of Adeno-Associated Virus 9 in a Symptomatic Mouse Model.

Fabry disease (FD) is an inherited lysosomal storage disease caused by deficiency of α-galactosidase A (α-Gal A), an enzyme that hydrolyzes glycosphingolipids in lysosome. Accumulation of glycosphingolipids, mainly globotriaosylceramide (Gb3) in tissues, induces cellular dysfunction leading to multi-organ disorder. Gene therapy is a promising strategy that can overcome these problems, and virus vectors such as adeno-associated virus (AAV) have been used for study on gene therapy. We used human Gb3 synthetase-transgenic (TgG3S)/α-Gal A knockout (GLAko) mice. TgG3S/GLAko mice have elevated Gb3 accumulation in the major organs compared with GLAko mice, which have been widely used as a model for FD. At the age of 6 weeks, male TgG3S/GLAko were injected with 2 × 1012 vector genome AAV9 vectors containing human α-Gal A cDNA. Eight weeks after intravenous injection of AAV, α-Gal A enzymatic activity was elevated in the plasma, heart, and liver of TgG3S/GLAko mice to levels corresponding to 224%, 293%, and 105% of wild-type, respectively. Gb3 amount 8 weeks after AAV injection in the heart and liver of this group was successfully reduced to levels corresponding to 16% and 3% of untreated TgG3S/GLAko mice. Although the brain and kidney of AAV9-treated TgG3S/GLAko mice showed no significant increases in α-Gal A activity, Gb3 amount was smaller than untreated littermates (48% and 44%, respectively). In this study, systemic AAV administration did not show significant extension of the lifespan of TgG3S/GLAko mice compared with the untreated littermates. The timing of AAV injection, capsid choice, administration route, and injection volume may be important to achieve sufficient expression of α-Gal A in the whole body for the amelioration of lifespan.

Outcomes and management of kidney transplant recipients with Fabry disease: a review.

Fabry disease is an X-linked inheritable lysosomal storage disease caused by various mutations of the galactosidase α gene resulting in α-galactosidase deficiency. Chronic kidney disease (CKD) is one of the most significant consequences of Fabry disease, with risk of end-stage kidney disease (ESKD) in this population. Like for other patients with ESKD, kidney transplant is the optimal treatment for Fabry disease patients with ESKD. However, enzyme replacement therapy and newer Fabry disease treatments remain important to mitigate other end organ damage such as cardiomyopathy post transplantation. This review is a primer on Fabry disease, which examines the outcomes of disease in the context of kidney transplant prior to, and during, the enzyme replacement treatment era, medical treatment of kidney transplant recipients with Fabry disease, and progress in screening studies.

Fabry disease: genetics, pathology, and treatment

SUMMARY Fabry disease (FD) is a recessive monogenic inheritance disease linked to chromosome X, secondary to mutations in the GLA gene. Its prevalence is estimated between 1:8,454 and 1:117,000 among males and is probably underdiagnosed. Mutations in the GLA gene lead to the progressive accumulation of globotriaosylceramide (Gb3). Gb3 accumulates in lysosomes of different types of cells of the heart, kidneys, skin, eyes, central nervous system, and gastrointestinal system, and may lead to different clinical scenarios. The onset of symptoms occurs during childhood, with acroparesthesia, heat intolerance, and gastrointestinal symptoms, such as nausea, vomiting, abdominal pain, and neuropathic pain. Subsequently, symptoms related to progressive impairment appear, such as angiokeratomas, cornea verticillata, left ventricular hypertrophy, myocardial fibrosis, proteinuria, and renal insufficiency. The latter being the main cause of death in FD. The gold standard for diagnosis is the genetic analysis in search of mutation, in addition to family history. In homozygous patients, the enzyme activity can also be used. Once the diagnosis is confirmed, the patient and their family should receive genetic counseling. The treatment, in turn, currently focuses mainly on replacing the enzyme that is absent or deficient by means of enzyme replacement therapy, with the purpose of avoiding or removing deposits of Gb3. Chaperones can also be used for the treatment of some cases. It is considered that the specific treatment should be initiated as soon as a diagnosis is obtained, which can change the prognosis of the disease.

Rare inherited kidney diseases: an evolving field in Nephrology / Doenças renais hereditárias raras: um campo em evolução na Nefrologia

Abstract There are more than 150 different rare genetic kidney diseases. They can be classified according to diagnostic findings as (i) disorders of growth and structure, (ii) glomerular diseases, (iii) tubular, and (iv) metabolic diseases. In recent years, there has been a shift of paradigm in this field. Molecular testing has become more accessible, our understanding of the underlying pathophysiologic mechanisms of these diseases has evolved, and new therapeutic strategies have become more available. Therefore, the role of nephrologists has progressively shifted from a mere spectator to an active player, part of a multidisciplinary team in the diagnosis and treatment of these disorders. This article provides an overview of the recent advances in rare hereditary kidney disorders by discussing the genetic aspects, clinical manifestations, diagnostic, and therapeutic approaches of some of these disorders, named familial focal and segmental glomerulosclerosis, tuberous sclerosis complex, Fabry nephropathy, and MYH-9 related disorder.

Acometimento renal na doença de Fabry / Renal involvement in Fabry disease

Resumo Todas as células do corpo humano apresentam acúmulo de globotriaosilceramida (Gb3) na doença de Fabry devido à mutação que ocorre no gene da enzima α-galactosidase A. Trata-se de uma doença ligada ao sexo. Os achados clínicos são: angioqueratomas cutâneos; acroparestesias e acidentes vasculares encefálicos precoces; sudorese diminuída e intolerância ao calor; alterações oculares; hipertrofia miocárdica, arritmias; alterações gastrointestinais e renais. O envolvimento renal ocorre devido ao acúmulo do Gb3 em todos os tipos de células renais. Portanto, os pacientes podem apresentar distúrbios das funções glomerulares e tubulares. Os podócitos são particularmente acometidos, com apagamento dos pedicélios e desenvolvimento de proteinúria. O diagnóstico é feito por meio da detecção de reduzida atividade plasmática ou leucocitária da α-galactosidase e pela detecção da mutação do gene da α-galactosidase. O tratamento com reposição enzimática contribui para o retardo da progressão da doença renal, principalmente se instituído precocemente.

Abstract Every cell in the human body has globotriaosylceramide accumulation (Gb3) in Fabry disease due to the mutation in gene of the enzyme α-galactosidase A. It is a disease linked to sex. The main clinical features are: cutaneous angiokeratomas; acroparestesias and early strokes; decreased sweating and heat intolerance; ocular changes; myocardial hypertrophy, arrhythmias; gastrointestinal disorders and renal involvement. Renal involvement occurs due to Gb3 accumulation in all types of renal cells. Therefore, patients may present glomerular and tubular function disorders. Podocytes are particularly affected, with pedicels effacement and development of proteinuria. The diagnosis is made by detection of reduced plasma or leukocyte α-galactosidase activity and genetic study for detecting the α-galactosidase gene mutation. Treatment with enzyme replacement contributes to delay the progression of kidney disease, especially if initiated early.

Terapia de reemplazo enzimático en la Enfermedad de Fabry: la dosis es importante / Enzyme replacement therapy in Fabry Disease: the importance of dose

La enfermedad de Fabry es una enfermedad rara ligada al X consecuencia de la deficiencia de α-galactosidasa A lisosomal, lo que genera un depósito excesivo de glicoesfingolípidos, predominantemente globotriaosilceramida (Gl3) y mortalidad de causa renal cardíaca y neurológica. El tratamiento actual consiste en la terapia de reemplazo enzimático, lo que intenta reemplazar por vía intravenosa la enzima deficiente. Existen en el mercado europeo y latinoamericano dos formulaciones de agalsidasa: agalsidasa alfa y agalsidasa beta, lo que permite al médico elegir el tratamiento. Sin embargo, la Food and Drug Administration en Estados Unidos rechazó aprobar la agalsidasa alfa. La diferencia fundamental entre agalsidasa alfa y agalsidasa beta es la dosis autorizada: 0,2 mg/kg y 1 mg/kg cada dos semanas respectivamente. Durante años esta diferencia tan grande de dosis sorprendió a los clínicos. Sin embargo varios estudios recientes sugieren que hay un efecto dosis-respuesta y que para algunos pacientes la dosis de 0,2 mg/kg cada dos semanas puede ser insuficiente. Sin embargo, no existen herramientas que permitan predecir que pacientes van a necesitar una dosis más alta para detener o enlentecer la progresión de la enfermedad. En esta revisión resumimos el estado actual del conocimiento sobre el impacto Tratamiento en la enfermedad de Fabry de las diferentes dosis y su eficacia en tratamiento de la enfermedad de Fabry.

Fabry disease is a rare X-linked inherited disorder due to deficient or absent lysosomal α-galactosidase A activity, resulting in an excessive glycosphingolipid deposit, mainly globotriaosylceramide (gl3) and mortality due renal, cardiac and neurological cause. Current treatment available is enzyme replacement therapy, where the deficient enzyme is substituted. In Latinamerica and Europe two different formulations of agalsidase (alfa and beta) are available. Food and Drug Administration in United States did not approve agalsidasa Alfa. The main difference among these formulations is the licensed dose: 0.2 mg/kg every other week for Alfa and 1 mg/kg every other week for Beta. Recent studies suggest a dose-dependent response, making 0.2 mg/kg every other week not sufficient in some patients. However there are no tools to predict which patients need a higher dose for preventing or decreasing the disease progression. This review, summarize the current knowledge about the impact of different dose and its efficacy in Fabry disease.

La gran variabilidad en su expresión clínica, las dificultades para su diagnóstico y la disponibilidad actual de varias alternativas para su tratamiento suponen un gran reto que justifica la realización de una guía de práctica clínica basada en la evidencia que pueda ayudar a los profesionales sanitarios en la toma de decisiones en el manejo de estos pacientes. Para elaborarla se ha realizado una búsqueda sistemática en las principales bases de datos bibliográficas mediante estrategias adaptadas a cada una de las 32 preguntas clínicas consideradas. Se confeccionaron fichas para la síntesis y evaluación de la calidad de las evidencias para cada una de las preguntas. La metodología empleada se basa en el Manual metodológico español para la elaboración de guías de práctica clínica e incorpora en la evaluación de la evidencia científica y en la elaboración de las recomendaciones la metodología GRADE, considerando la calidad de la evidencia, el balance entre beneficios y riesgos, valores y preferencias de los pacientes, equidad y uso de recursos. Para la elaboración definitiva de las recomendaciones se llevó a cabo un proceso de consenso estructurado basado en la metodología Delphi-RAND en 2 rondas, con un panel de expertos propuesto por diferentes sociedades científicas, centros de investigación y asociaciones de pacientes. Finalmente, se han elaborado 92 recomendaciones específicas para el manejo de la enfermedad de Fabry

Anderson-Fabry disease is a severe progressive multisystem condition of genetic origin that affects men and women, reducing their life expectancy and quality of life. The considerable variability in its clinical expression, the difficulties in diagnosing the condition and the current availability of several alternatives for its treatment represent a considerable challenge that justifies the development of evidence-based clinical practice guidelines that can help health professionals in the decision-making process for managing these patients. To develop these guidelines, we conducted a systematic search of the main reference databases using strategies adapted to each of the 32 clinical questions considered. We prepared documents to synthesise the evidence and assess its quality for each of the questions. The methodology employed is based on the Spanish methodology manual for preparing clinical practice guidelines, incorporating the GRADE methodology in the assessment of the scientific evidence and the preparation of the recommendations, considering the quality of the evidence, the risk-benefit balance, patient values and preferences, equity and use of resources. For the definitive preparation of the recommendations, we conducted a structured consensus process based on the Delphi-RAND methodology in 2 rounds, with an expert panel proposed by various scientific societies, research centres and patient associations. Ultimately, we developed 92 specific recommendations for managing Fabry disease

Enfermedad de Fabry: la importancia de la terapia de reemplazo enzimático (TRE): tratar rápida y eficazmente / Fabry Disease: the importance of the, enzyme replacement therapy (TRE): treating quickly and efficiently

La enfermedad de Fabry en un trastorno lisosomal por ausencia o deficiencia de la enzima Alfa galactosidasa A que genera un acúmulo patológico de glicoesfingolípidos principalmente en células endoteliales, musculares lisas de vasos sanguíneos y podocitos entre otras. La terapia de reemplazo enzimático es la única chance de tratamiento específico a la fecha. El creciente conocimiento de los mecanismos fisiopatológicos ha llevado a cambiar el manejo de la enfermedad y por sobretodo el momento de inicio del tratamiento. Actualmente el inicio en edades más tempranas parece ser una forma de evitar y en algunos casos revertir algunos de los signos y síntomas de la enfermedad de Fabry.

Fabry Disease is a lysosomal disorder due to the absence or deficiency of the Alpha galactosidase A enzyme that causes a pathological ac cumulation of glycosphingolipids mainly in the REVISIÓN endothelial cells, vascular smooth muscle cells and podocytes among others. Enzyme replacement therapy is the only option for a specific treatment at present. Increasing knowledge of the physiopathological mechanisms has changed the management of the disease and above all, when treatment should begin. At present, beginning treatment at an early age seems to be a way of preventing and in some cases reverting some of the signs and symptoms of Fabry disease.

Tratamiento en la enfermedad de Fabry / Treatment in Fabry disease

La enfermedad de Fabry es una enfermedad ligada al cromosomaX causada por un déficit de alfa-galactosidasaA. Esto da como resultado la acumulación de glicoesfingolípidos en todas las células y tejidos. Todos los varones deben tratarse con reemplazo enzimático en caso de presentar niveles muy bajos o indetectables de alfa-galactosidasaA. Las mujeres portadoras y los varones con niveles mínimos de alfa-galactosidasaA deben tratarse si existe afectación renal, neurológica o cardíaca. Para terapia de reemplazo enzimático existen dos formulaciones intravenosas, agalsidasa alfa y agalsidasa beta, que muestran una eficacia y seguridad similares. Los pacientes con mutaciones susceptibles del gen alfa-galactosidasaA pueden tratarse con migalastat oral. El migalastat es una molécula que facilita el paso de alfa-galactosidasaA a los lisosomas, produciendo aumento de actividad del enzima. Los pacientes tratados con migalastat muestran mejoras significativas en la masa del ventrículo izquierdo y en los síntomas gastrointestinales

Fabry disease is an X-linked inborn disease caused by deficit of alpha-galactosidaseA. This results in accumulation of glycosphingolipids in all cells and tissues. All males should receive enzyme replacement treatment in case of very low or undetectable levels of alpha-galactosidaseA. Female carriers and males with marginally levels of alpha-galactosidaseA should be treated in case of renal, neurologic o cardiac manifestations. There are two intravenous formulations of human recombinant enzyme, agalsidase alpha and agalsidase beta, showing similar efficacy and safety. Patients with amenable mutations of alpha-galactosidase can be treated with oral migalastat hydrochloride. Migalastat hydrochloride is a pharmacological chaperone that facilitates trafficking of alpha-galactosidaseA to lysosomes increasing enzyme activity. Patients treated with migalastat hydrochloride had significant improvements in left ventricular mass and gastrointestinal symptoms
