Abstract
Enzyme replacement therapy (ERT) has been used to treat a few of the many existing diseases which are originated from the lack of, or low enzymatic activity. Exogenous enzymes are administered to contend with the enzymatic activity deficiency. Enzymatic nanoreactors based on the enzyme encapsulation inside of virus-like particles (VLPs) appear as an interesting alternative for ERT. VLPs are excellent delivery vehicles for therapeutic enzymes as they are biodegradable, uniformly organized, and porous nanostructures that transport and could protect the biocatalyst from the external environment without much affecting the bioactivity. Consequently, significant efforts have been made in the production processes of virus-based enzymatic nanoreactors and their functionalization, which are critically reviewed. The use of virus-based enzymatic nanoreactors for the treatment of lysosomal storage diseases such as Gaucher, Fabry, and Pompe diseases, as well as potential therapies for galactosemia, and Hurler and Hunter syndromes are discussed.

Abstract
Heterozygous loss-of-function mutations in progranulin (GRN) cause frontotemporal dementia (FTD), a leading cause of early-onset dementia characterized clinically by behavioral, social, and language deficits. There are currently no FDA-approved therapeutics for FTD-GRN, but this has been an active area of investigation, and several approaches are now in clinical trials. Here, we review preclinical development of therapies for FTD-GRN with a focus on testing in mouse models. Since most FTD-GRN-associated mutations cause progranulin haploinsufficiency, these approaches focus on raising progranulin levels. We begin by considering the disorders associated with altered progranulin levels, and then review the basics of progranulin biology including its lysosomal, neurotrophic, and immunomodulatory functions. We discuss mouse models of progranulin insufficiency and how they have been used in preclinical studies on a variety of therapeutic approaches. These include approaches to raise progranulin expression from the normal allele or facilitate progranulin production by the mutant allele, as well as approaches to directly increase progranulin levels by delivery across the blood-brain barrier or by gene therapy. Several of these approaches have entered clinical trials, providing hope that new therapies for FTD-GRN may be the next frontier in the treatment of neurodegenerative disease.

Clinical relevance of globotriaosylceramide accumulation in Fabry disease and the effect of agalsidase beta in affected tissues. Mol Genet Metab 2022; 137:328-341.

Abstract
Fabry disease (FD) is a rare lysosomal storage disorder, characterized by a reduction in α-galactosidase A enzyme activity and the progressive accumulation of globotriaosylceramide (GL3) and its metabolites in the cells of various organs. Agalsidase beta, an enzyme replacement therapy (ERT), is approved for use in patients with FD in Europe, Canada, Australia, South America, and Asia, and is the only ERT approved for use in the United States. In this review, we discuss the clinical relevance of GL3 accumulation, the effect of agalsidase beta on GL3 in target tissues, and the association between treatment-related tissue GL3 clearance and long-term structure, function, or clinical outcomes. Accumulation of GL3 in the kidney, heart, vasculature, neurons, skin, gastrointestinal tract and auditory system correlates to cellular damage and irreversible organ damage, as a result of sclerosis, fibrosis, apoptosis, inflammation, and endothelial dysfunction. Damage leads to renal dysfunction and end-stage renal disease; myocardial hypertrophy with heart failure and arrhythmias; ischemic stroke; neuropathic pain; skin lesions; intestinal ischemia and dysmotility; and hearing loss. Treatment with agalsidase beta is effective in substantially clearing GL3 in a range of cells from the tissues affected by FD. Agalsidase beta has also been shown to slow renal decline and lower the overall risk of clinical progression, demonstrating an indirect link between treatment-related GL3 clearance and stabilization of FD.

Abstract
OBJECTIVE The objective of this review was to investigate the experiences of patients with lysosomal storage disorders who are receiving enzyme-replacement therapy and the experiences of their family members. INTRODUCTION Lysosomal storage disorders are rare diseases caused by mutations in the genes that encode proteins required for lysosomal function. The age of onset of these disorders varies from infancy to adulthood, depending on the specific disease and type. Enzyme-replacement therapy is the standard treatment for some lysosomal storage disorders. However, patients' adherence to this treatment is affected not only by the resultant changes (or lack thereof) in their symptoms, but also by the scheduling of the frequent hospital visits necessary to receive this treatment. No previous qualitative systematic review has examined the experiences of these patients and their families. INCLUSION CRITERIA Qualitative studies on the experiences of patients with lysosomal storage disorders who were receiving enzyme-replacement therapy and/or the experiences of the family members of these patients were included. These experiences could include satisfaction/dissatisfaction with diagnosis, difficulties and expectations regarding continuing treatment, advantages/disadvantages concerning school and work life, the psychological burden on families, and the support provided by families. This review considered studies in all settings because relevant experiences may occur outside medical institutions. METHODS MEDLINE, CINAHL Plus, APA PsycINFO, Scopus, and Igaku Chuo Zasshi were searched for articles published between January 1991 and May 13, 2021. No language restrictions were applied. The study selection, critical appraisal, data extraction, and data synthesis were performed in accordance with the JBI methodology for systematic reviews of qualitative evidence. RESULTS Seven studies were included in this review, from which 37 findings with narrative illustrations were extracted; of these, 33 were assessed as unequivocal and four as credible. These findings were integrated into 10 categories and three synthesized findings. The first synthesized finding was encouraging awareness of the minor changes in physical symptoms caused by the treatment, which contains categories such as physical change caused by treatment. The second synthesized finding was supporting acceptance of the disease and coping with associated psychological challenges, which contains categories such as concerns regarding the future. The third synthesized finding was customization of treatment plans to minimize restrictions on the lives of patients and their families, which contains categories such as restrictions on patients' lives. According to the ConQual criteria, all three synthesized findings had low confidence levels. CONCLUSION Evidence obtained through the synthesized findings produced in this review identified the primary experiences of patients with lysosomal storage disorders who are receiving enzyme-replacement therapy and their family members. These experiences concerned challenges regarding physical, psychological, and social health. When supporting patients with lysosomal storage disorders and their families, it is necessary to consider not only the symptoms and treatments but also the mental and social aspects.

Abstract
Fabry disease (FD) is a rare genetic lysosomal storage disorder, resulting from partial or complete lack of alpha-galactosidase A (α-GAL) enzyme, leading to systemic accumulation of substrate glycosphingolipids with a broad range of tissue damage. Current in vivo models are laborious, expensive, and fail to adequately mirror the complex FD physiopathology. To address these issues, we developed an innovative FD model in zebrafish. Zebrafish GLA gene encoding α-GAL enzyme presents a high (>70%) homology with its human counterpart, and the corresponding protein has a similar tissue distribution, as evaluated by immunohistochemistry. Moreover, a similar enzymatic activity in different life stages could be demonstrated. By using CRISPR/Cas9 technology, we generated a mutant zebrafish with decreased GLA gene expression, and decreased expression of the specific gene product in the kidney. Mutant animals showed higher plasma creatinine levels and proteinuria. Transmission electron microscopy (TEM) studies documented an increased podocyte foot process width (FPW) in mutant, as compared to wild type zebrafish. This zebrafish model reliably mirrors distinct features of human FD and could be advantageously used for the identification of novel biomarkers and for an effective screening of innovative therapeutic approaches.

Abstract
Fabry disease (FD) is a relatively rare X-linked hereditary disease caused by mutations in the GLA gene that results in deficient α-galactosidase A (α-Gal A) enzyme activity. The disturbed catabolism of the neutral sphingolipids globotriaosylceramide (Gb3) leads to its progressive lysosomal accumulation throughout the body. Multiple organs can be affected. The atypical late-onset cardiac variant is associated with a high burden of cardiac morbidity and mortality. The aim of this work was to present an updated overview of the FD, with focus on cardiovascular manifestations and its management. Enzyme replacement therapy (ERT) is nowadays an established treatment of FD and is recommended as early as possible with or without chaperone therapy (migalastat) to prevent or delay the progression of renal, cardiac, and cerebrovascular complications. It improves quality of life and may further result in decrease in Left ventricular (LV) mass and to some extent LV function recovery. However, LV hypertrophy (LVH) does not always respond well to ERT despite successful Gb3 clearance. Furthermore, its impact on the hard clinical events is uncertain. Some possible reasons for this apparent discrepancy are discussed. ERT may be less effective in patients who have already developed fibrosis or irreversible organ damage. However, other confounding factors may be equally important.

Abstract
Enzyme replacement therapy (ERT) is a mainstay of treatment for Anderson-Fabry disease (AFD), a pathology with negative effects on the heart and kidneys. However, no reliable biomarkers are available to monitor its efficacy. Therefore, we tested a panel of four microRNAs linked with cardiac and renal damage in order to identify a novel biomarker associated with AFD and modulated by ERT. To this end, 60 patients with a definite diagnosis of AFD and on chronic ERT, and 29 age- and sex-matched healthy individuals, were enrolled by two Italian university hospitals. Only miR-184 met both conditions: its level discriminated untreated AFD patients from healthy individuals (c-statistic = 0.7522), and it was upregulated upon ERT (P < 0.001). On multivariable analysis, miR-184 was independently and inversely associated with a higher risk of cardiac damage (odds ratio = 0.86; 95% confidence interval [CI] = 0.76-0.98; P = 0.026). Adding miR-184 to a comprehensive clinical model improved the prediction of cardiac damage in terms of global model fit, calibration, discrimination, and classification accuracy (continuous net reclassification improvement = 0.917, P < 0.001; integrated discrimination improvement [IDI] = 0.105, P = 0.017; relative IDI = 0.221, 95% CI = 0.002-0.356). Thus, miR-184 is a circulating biomarker of AFD that changes after ERT. Assessment of its level in plasma could be clinically valuable in improving the prediction of cardiac damage in AFD patients.

Abstract
We herein report the case of a 53-year-old man who was historically diagnosed with hypertrophic cardiomyopathy (HCM) and was lost to follow-up, before presenting with end-stage heart failure. This was initially suspected as dilated cardiomyopathy and then 'burnt-out phase' of HCM but subsequently the underlying diagnosis was Fabry disease. Fabry disease is an uncommon lysosomal-storage disease due to reduced or absent activity of the alpha-galactosidase A enzyme. Cardiac involvement most frequently comprises left ventricular hypertrophy. Early treatment of the underlying condition with enzyme replacement therapy may prevent the progression to end-stage heart failure. Fabry disease should be considered in all patients presenting with a clinical phenotype of HCM and a historical diagnosis should be re-evaluated in light of new diagnostic tools. Untreated Fabry can progress to a 'burnt out' phase, whereby initial hypertrophy undergoes eccentric remodelling to a dilated, severely impaired left ventricle.

Abstract
Fabry disease (FD) causes life-long pain, the mechanisms of which are unclear. Patients with FD have chronic pain that mirrors symptoms of other painful peripheral neuropathies. However, it is unclear what underlying damage occurs in FD peripheral nerves that may contribute to chronic pain. Here, we characterized myelinated and unmyelinated fiber pathology in peripheral nerves of a rat model of FD. Decreased nerve fiber density and increased nerve fiber pathology were noted in unmyelinated and myelinated fibers from FD rats; both observations were dependent on sampled nerve fiber modality and anatomical location. FD myelinated axons exhibited lipid accumulations that were determined to be the FD-associated lipid globotriaosylceramide (Gb3), and to a lesser extent lysosomes. These findings suggest that axonal Gb3 accumulation may drive peripheral neuron dysfunction and subsequent pain in FD.

Abstract
Fabry disease (FD) is an X-linked hereditary disease. It results from mutations in the GLA gene, leading to deficient activity of the enzyme alpha-galactosidase A (α-Gal A) and progressive accumulation of undegraded glycosphingolipids in cell lysosomes. Enzyme replacement therapy (ERT) can improve the natural course of this disease, but an early diagnosis is crucial for a successful treatment. We describe the case of a female diagnosed with chronic proteinuric kidney disease in the postpartum period. Despite receiving optimal medical treatment, the disease progressed and she started renal replacement therapy (RRT) with peritoneal dialysis (PD). Five years later, she was enrolled in a pilot screening study for FD, and the heterozygous mutation c.870G>C (p.Met290Ile; M290I) in exon six of the GLA gene was found. The family screening revealed the presence of this mutation in the patient's father and daughter. The proband did not meet the criteria for a definitive FD diagnosis, but she remained under follow-up at our nephrology metabolic diseases consultation, as the mutation was described as pathogenic and associated with a classic FD phenotype. Later that same year, reassessment exams revealed a worsening left ventricle mass index (LVMi), a new ischemic cerebral lesion, and a substantial increase in serum globotriaosylsphingosine (LysoGb3) levels. These clinical changes led to a decision to initiate ERT. p.M290I is a previously known but poorly described GLA mutation. To our knowledge, this is the first report of p.M290I mutation-associated disease activity that offers strong evidence of its pathogenicity.

Abstract
BACKGROUND The inability of enzyme replacement therapy (ERT) to prevent progression of Fabry nephropathy (FN) in the presence of >1 g/day proteinuria underscores the necessity of identifying effective biomarkers for early diagnosis of FN preceding proteinuria. Here we attempted to identify biomarkers for early detection of FN. METHODS Fifty-one Fabry disease (FD) patients were enrolled. Urinary mulberry bodies (uMBs) were immunostained for globotriaosylceramide (Gb3) and renal cell markers to determine their origin. The association between semiquantitative uMB excretion and the histological severity of podocyte vacuolation was investigated in seven patients using the vacuolated podocyte:glomerular average area ratio. The association between the semiquantitative estimate of uMB excretion and duration of ERT was analyzed. A longitudinal study was conducted to assess the effect of ERT on uMB excretion. RESULTS Thirty-two patients (63%) had uMBs, while only 31% showed proteinuria. The uMBs were positive for Gb3, lysosomal-associated membrane protein 1 and podocalyxin, suggesting they were derived from lysosomes with Gb3 accumulation in podocytes. We observed more severe podocyte vacuolation with increased uMB excretion (P = 0.03 for trend); however, the same was not observed with increased proteinuria. The percentage of patients with substantial uMB excretion increased with shorter ERT duration (P = 0.018). Eighteen-month-long ERT reduced uMB excretion (P = 0.03) without affecting proteinuria. CONCLUSIONS uMB excretion, implying ongoing podocyte injury, preceded proteinuria in most patients. Semiquantitative uMB estimates can serve as novel biomarkers for early FN diagnosis and for monitoring the efficacy of FD-specific therapies.

Abstract
OBJECTIVE The objective of the review is to investigate the experiences of patients with lysosomal storage disorders treated with enzyme replacement therapy and the experiences of their families. INTRODUCTION Lysosomal storage disorders are rare diseases caused by mutations in genes encoding proteins required for lysosomal function. The onset of lysosomal storage disorders vary from infancy to adulthood, depending on the specific disease and disease type. Enzyme replacement therapy is the standard treatment for some lysosomal storage disorders. The adherence to the treatment by patients and their families is affected not only by the symptoms but also by the scheduling of hospital visits. No qualitative systematic review on this topic has examined the experiences of patients and their families. INCLUSION CRITERIA Qualitative studies dealing with the experiences of patients with lysosomal storage disorders receiving enzyme replacement therapy and their families will be included. These may include experiences related to satisfaction or dissatisfaction with being diagnosed, difficulties and expectations continuing treatment, the advantages or disadvantages related to school and work life, and the psychological burden and supports on families. This review will consider studies in all settings because relevant experiences of patients and their families may occur outside medical institutions. METHODS MEDLINE, CINAHL Plus, APA PsycINFO, Scopus, and Igaku Chuo Zasshi databases will be examined from 1991 to the present. Studies published in any language will be included. The study selection, critical appraisal, data extraction, and data synthesis will be performed in accordance with the guidelines for systematic reviews of qualitative evidence in the JBI Manual for Evidence Synthesis. SYSTEMATIC REVIEW REGISTRATION NUMBER PROSPERO CRD42019147751.

Abstract
Results from the 18-month randomized treatment period of the phase 3 ATTRACT study demonstrated the efficacy and safety of oral migalastat compared with enzyme replacement therapy (ERT) in patients with Fabry disease who previously received ERT. Here, we report data from the subsequent 12-month, migalastat-only, open-label extension (OLE) period. ATTRACT (Study AT1001-012; NCT01218659) was a randomized, open-label, active-controlled study in patients aged 16-74 years with Fabry disease, an amenable GLA variant, and an estimated glomerular filtration rate (eGFR) ≥30 mL/min/1.73 m2. During the OLE, patients who received migalastat 150 mg every other day (QOD) during the randomized period continued receiving migalastat (Group 1 [MM]); patients who received ERT every other week discontinued ERT and started migalastat treatment (Group 2 [EM]). Outcome measures included eGFR, left ventricular mass index (LVMi), composite clinical outcome (renal, cardiac or cerebrovascular events), and safety. Forty-six patients who completed the randomized treatment period continued into the OLE (Group 1 [MM], n = 31; Group 2 [EM], n = 15). eGFR remained stable in both treatment groups. LVMi decreased from baseline at month 30 in Group 1 (MM) in patients with left ventricular hypertrophy at baseline. Only 10% of patients experienced a new composite clinical event with migalastat treatment during the OLE. No new safety concerns were reported. In conclusion, in patients with Fabry disease and amenable GLA variants, migalastat 150 mg QOD was well tolerated and demonstrated durable, long-term stability of renal function and reduction in LVMi.

Left Ventricular Mass and Wall Thickness Measurements Using Echocardiography and Cardiac MRI in Patients with Fabry Disease: Clinical Significance of Discrepant Findings. Radiol Cardiothorac Imaging 2020; 2:e190149. [PMID: 33778580 DOI: 10.1148/ryct.2020190149] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2019] [Revised: 11/27/2019] [Accepted: 12/23/2019] [Indexed: 12/22/2022]
Abstract
Purpose To compare transthoracic echocardiography (TTE) and cardiac MRI measurements of left ventricular mass (LVM) and maximum wall thickness (MWT) in patients with Fabry disease and evaluate the clinical significance of discrepancies between modalities. Materials and Methods Seventy-eight patients with Fabry disease (mean age, 46 years ± 14 [standard deviation]; 63% female) who underwent TTE and cardiac MRI within a 6-month interval between 2008 and 2018 were included in this retrospective cohort study. The clinical significance of measurement discrepancies was evaluated with respect to diagnosis of left ventricular hypertrophy (LVH), eligibility for disease-specific therapy, and prognosis. Statistical analysis included paired-sample t test, Cox proportional hazard models, Akaike information criterion (AIC), and intraclass correlation coefficients. Results LVM indexed to body surface area (LVMI) and MWT were significantly higher at TTE compared with MRI (105 g/m2 ± 48 vs 78 g/m2 ± 36, P < .001 and 14 mm ± 4 vs 13 mm ± 5, P = .008, respectively). LVH classification was discordant between modalities in 23 patients (29%) (P < .001). Eligibility for disease-specific therapy based on MWT was discordant between modalities in 20 patients (26%) (P < .001). LVMI assessed with MRI was a better predictor of the combined endpoint compared with LVMI assessed with TTE (AIC, 127 vs 131). Interobserver agreement for LVMI and MWT was higher for MRI (intraclass correlation coefficient, 0.951 and 0.912, respectively) compared with TTE (intraclass correlation coefficient, 0.940 and 0.871; respectively). Conclusion TTE overestimates LVM and MWT and has lower reproducibility compared with cardiac MRI in Fabry disease. Measurement discrepancies between modalities are clinically significant with respect to diagnosis of LVH, prognosis, and treatment decisions.© RSNA, 2020.

Abstract
Fabry disease (FD) is one of the most common lysosomal storage disorders and is caused by an X-linked progressive inborn error of metabolism in the alpha-galactosidase A (α-Gal A) gene. This leads to intracellular accumulation of glycosphingolipids, mainly globotriaosylceramide (Gb3), throughout the body. The impact of this accumulation is seen across multiple cell lines and therefore can cause multisystem organ dysfunction. The phenotype of FD results from variants on the GLA gene which codes for α-Gal A production, and variants on this gene have been shown to be strongly related to unexplained or idiopathic cardiovascular disorders. This report describes a 36-year-old Caucasian male found to have left ventricular hypertrophy (LVH) followed by genetic testing because of his family history of sudden cardiac death which revealed a variant of unknown significance for the GLA gene. Further measurement of α-Gal A leukocyte activity showed low levels, which was diagnostic for FD. The index patient had an unusual non-classic phenotype in that his sole presenting symptom was asymptomatic LVH, he presented early, and had low α-Gal A leukocyte activity. Early detection and prompt treatment with enzyme replacement therapy can improve outcomes and decrease mortality. In the absence of known risk factors, non-classical FD should be strongly considered in patients with unexplained LVH and a family history of sudden cardiac death at a young age.

Abstract
α-Galactosidase, (E.C. 3.2.1.22) is an exoglycosidase that target galactooligosaccharides such as raffinose, melibiose, stachyose and branched polysaccharides like galactomannans and galacto-glucomannans by catalysing the hydrolysis of α-1,6 linked terminal galactose residues. The enzyme has been isolated and characterized from microbial, plant and animal sources. This ubiquitous enzyme possesses physiological significance and immense industrial potential. Optimization of the growth conditions and efficient purification strategies can lead to a significant increase in the enzyme production. To boost commercial productivity, cloning of novel α-galactosidase genes and their heterologous expression in suitable host has gained popularity. Enzyme immobilization leads to its greater reutilization, superior thermostability, pH tolerance and increased activity. The enzyme is well explored in food industry in the removal of raffinose family oligosaccharides (RFOs) in soymilk and sugar crystallization process. It also improves animal feed quality and biomass processing. Applications of the enzyme is in the area of biomedicine includes therapeutic advances in treatment of Fabry disease, blood group conversion and removal of α-gal type immunogenic epitopes in xenotransplantation. With considerable biotechnological applications, this enzyme has been vastly commercialized and holds greater future prospects.

Abstract
Fabry disease is an X-linked inherited, progressive disorder of lipid metabolism resulting from the deficient activity of the enzyme α-galactosidase. Enzyme replacement therapy (ERT) with recombinant agalsidase, with intravenous infusions of either agalsidase beta or agalsidase alfa, is available and clinical experience now exceeds 15 years. There are very few randomised, placebo-controlled clinical trials evaluating the outcomes of ERT. Data are often derived from observational, registry-based studies and case reports. Pooled analysis of data from different sources may be limited by the heterogeneity of the patient populations, outcomes and treatment. Therefore, comprehensive systematic literature reviews of unpooled data are needed to determine the effects of ERT on disease outcomes. A systematic literature search was conducted in the Embase and PubMed (MEDLINE) databases to retrieve original articles that evaluated outcomes of ERT in patients with Fabry disease; the outcome data were analysed unpooled. The literature analysis included the full range of published literature including observational studies and case series/case reports. Considerable heterogeneity was found among the studies, with differences in sample size, statistical methods, ERT regimens and patient demographic and clinical characteristics. We have demonstrated the value of performing an unpooled systematic literature review of all published evidence of ERT outcomes in Fabry disease, highlighting that in a rare genetic disorder like Fabry disease, which is phenotypically diverse, different patient populations can require different disease management and therapeutic goals depending on age, genotype, and disease severity/level of organ involvement. In addition, these findings are valuable to guide the design and reporting of new clinical studies.

Abstract
Current therapies have not shown benefit in organ damage reversal in Fabry disease (FD), but biomarkers could help risk stratification and prognosis. We investigated if several biomarkers of cardiac fibrosis, cardiac wall stress, myocardial injury, renal function and inflammation, are associated with early cardiac affectation in FD patients. We included FD patients from four cardiology outpatient clinics of southeastern Spain. At inclusion, Galectin-3 (Gal-3), N-terminal proB-type natriuretic peptide, high sensitivity troponin T (hsTnT), β-trace protein (BTP) and interleukin-6 concentrations were measured. The relation of biomarkers concentrations with clinical features, cardiac involvement and organ affectation according to the Mainz Severity Score Index (MSSI) was investigated. 44 FD patients (n = 21 affected and n = 23 unaffected) were compared to age and sex-respectively matched healthy controls. Significant differences in biomarkers’ concentration between FD groups were observed. Importantly, Gal-3 and BTP levels were higher in unaffected patients when compared with age and sex-matched healthy controls (both p < 0.05). All the biomarkers correlated with clinical features. When cut-off values for clinical affectation (measured as MSSI ≥ 20) were established, only hsTnT (OR 30.69, 95% CI 2.70–348.42) and male sex (OR 8.17, 95% CI 1.16–57.75) were independently associated with cardiac damage by multivariate regression analysis. Gal-3 and BTP levels are increased in unaffected FD patients compared to healthy controls. This suggests that these biomarkers could be useful for the early detection of cardiac affectation in FD patients. On the other hand, hsTnT and male sex are independent risk factors for established clinical cardiac damage in FD.

The effect of enzyme replacement therapy on clinical outcomes in male patients with Fabry disease: A systematic literature review by a European panel of experts. Mol Genet Metab Rep 2019; 19:100454. [PMID: 30775256 PMCID: PMC6365982 DOI: 10.1016/j.ymgmr.2019.100454] [Citation(s) in RCA: 88] [Impact Index Per Article: 17.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2019] [Accepted: 01/23/2019] [Indexed: 11/17/2022] Open
Abstract
Background Enzyme replacement therapy (ERT) with recombinant human α-galactosidase has been available for the treatment of Fabry disease since 2001 in Europe and 2003 in the USA. Treatment outcomes with ERT are dependent on baseline patient characteristics, and published data are derived from heterogeneous study populations. Methods We conducted a comprehensive systematic literature review of all original articles on ERT in the treatment of Fabry disease published up until January 2017. This article presents the findings in adult male patients. Results Clinical evidence for the efficacy of ERT in adult male patients was available from 166 publications including 36 clinical trial publications. ERT significantly decreases globotriaosylceramide levels in plasma, urine, and in different kidney, heart, and skin cell types, slows the decline in estimated glomerular filtration rate, and reduces/stabilizes left ventricular mass and cardiac wall thickness. ERT also improves nervous system, gastrointestinal, pain, and quality of life outcomes. Conclusions ERT is a disease-specific treatment for patients with Fabry disease that may provide clinical benefits on several outcomes and organ systems. Better outcomes may be observed when treatment is started at an early age prior to the development of organ damage such as chronic kidney disease or cardiac fibrosis. Consolidated evidence suggests a dose effect. Data described in male patients, together with female and paediatric data, informs clinical practice and therapeutic goals for individualized treatment.

Abstract
Primary hyperoxalurias (PHs) are rare inherited disorders of liver glyoxylate metabolism, characterized by the abnormal production of endogenous oxalate, a metabolic end-product that is eliminated by urine. The main symptoms are related to the precipitation of calcium oxalate crystals in the urinary tract with progressive renal damage and, in the most severe form named Primary Hyperoxaluria Type I (PH1), to systemic oxalosis. The therapies currently available for PH are either poorly effective, because they address the symptoms and not the causes of the disease, or highly invasive. In the last years, advances in our understanding of the molecular bases of PH have paved the way for the development of new therapeutic strategies. They include (i) substrate-reduction therapies based on small-molecule inhibitors or the RNA interference technology, (ii) gene therapy, (iii) enzyme administration approaches, (iv) colonization with oxalate-degrading intestinal microorganisms, and, in PH1, (v) design of pharmacological chaperones. This paper reviews the basic principles of these new therapeutic strategies and what is currently known about their application to PH.

Abstract
The critical relevance of the lysosomal compartment for normal cellular function can be proved by numbering the clinical phenotypes that arise in lysosomal storage disorders (LSDs), a group of around 70 different monogenic autosomal or X-linked syndromes, caused by specific lysosomal enzyme deficiencies: all LSDs are characterized by progressive accumulation of heterogeneous biologic materials in the lysosomes of various parts of the body such as viscera, skeleton, skin, heart, and central nervous system. At least a fraction of LSDs has been associated with mixed abnormalities involving the immune system, while some patients with LSDs may result more prone to autoimmune phenomena. A large production of proinflammatory cytokines has been observed in Gaucher and Fabry diseases, and wide different autoantibody production has been also reported in both. Many immune-mediated reactions are crucial to the pathogenesis of different inflammatory signs in mucopolysaccharidoses, and subverted heparan sulphate catabolism might dysregulate cellular homeostasis in the brain of these patients. Furthermore, an inappropriate activation of microglia is implicated in the neurodegenerative foci of Niemann-Pick disease, in which abnormal signalling pathways are activated by impaired sphingolipid metabolism. In addition, not the simple impaired catabolism of gangliosides per se, but also the production of anti-ganglioside autoantibodies contributes to the neurological disease of gangliosidoses. Even if the exact relationship between the modification of lysosomal activities and modulation of the immune system remains obscure, there is emerging evidence of different impaired immunity responses in a variety of LSDs: in this review we investigate and summarize the immune abnormalities and/or clinical data about immune system irregularities which have been described in a subset of LSDs.

Abstract
OBJECTIVES In patients with Fabry disease (FD), left ventricular hypertrophy and arrhythmias are frequently observed and cardiac involvement is the leading cause of death. Long-term efficacy of enzyme replacement therapy (ERT) on cardiac involvement is unclear. We assessed and compared long-term progression of cardiac involvement according to ERT and non-ERT. METHODS We retrospectively assessed and compared long-term progression of cardiac involvement in adult patients with FD in the nationwide Danish cohort. We followed clinical signs, symptoms and findings by echocardiography, electrocardiography and Holter-monitoring. RESULTS We included 66 patients; 47 patients (27 women) received ERT (ERT group) and 19 patients (15 women) did not (non-ERT group). The groups were followed for a median of 8 [0-12] years and 6 [0-13] years, respectively. Comparison between ERT and non-ERT receiving patients by left ventricular mass (echocardiographic assessment) and Sokolow-Lyon voltage- and Cornell product criteria (electrocardiographic assessment) revealed no significant differences. In the ERT group, we observed no change in left ventricular mass but a decrease in Sokolow-Lyon voltage- and Cornell product criteria from baseline to follow-up; 30 mm [15-53] vs. 25 mm [3-44], p < 0.005 and 1710 mm·ms [480-3740] vs. 1520 mm·ms [550-5740], p < .05, respectively. There were no changes within the non-ERT group. During follow-up, cardiac symptoms and use of cardiovascular procedures and -medication increased significantly in the ERT group, whereas no differences were observed within the non-ERT group. DISCUSSION We raise concerns regarding the efficacy and benefit of ERT on cardiac involvement in Fabry disease and stress the need for further research.

Abstract
BACKGROUND Fabry disease, an X-linked disorder of glycosphingolipids, markedly increases the risk of systemic vasculopathy, ischemic stroke, small-fiber peripheral neuropathy, cardiac dysfunction, and chronic kidney disease. METHODS We performed an extensive PubMed search on the topic of Fabry disease and drew from our cumulative 43 years of experience. RESULTS Most of these complications are nonspecific in nature and clinically indistinguishable from similar abnormalities that occur in the context of more common disorders in the general population. This disease is caused by variants of the GLA gene, and its incidence may have been underestimated. However, one must also guard against overdiagnosis of Fabry disease and unjustified enzyme replacement therapy, because some of the gene variants are benign. Specific therapy for Fabry disease has been developed in the last few years, but its clinical effect has been modest. Novel therapeutic agents are being developed. Standard "nonspecific" medical and surgical therapy is necessary and effective in slowing deterioration or compensating for organ failure in patients with Fabry disease. CONCLUSIONS Fabry disease is a treatable and modifiable genetic risk factor for a myriad of clinical organ complications. Fabry disease may be frequently overlooked but on occasion overdiagnosed.

Abstract
Fabry disease (Anderson-Fabry disease) is an X-linked recessive lysosomal storage disorder resulting from deficient activity of lysosomal hydrolase, alpha-galactosidase A (alpha-Gal A), which leads to progressive accumulation of globotriaosylceramide (Gb3) in various cells, predominantly endothelial and vascular smooth muscle cells, with clinical manifestations affecting major organs including the central nervous system. Manifestations of Fabry disease include progressive renal and cardiac insufficiency, neuropathic pain, stroke and cerebral disease, skin and gastrointestinal symptoms. Clinical onset usually occurs in childhood, but many severe patients are diagnosed in adulthood. Females may be severely affected as males and both may die prematurely due to stroke, heart disease and renal failure. Early recognition of symptoms, enzyme activity levels, concentration of Gb3 levels in the blood, urine and skin biopsies, as well as genetic testing (GLA gene) enable establishment of early diagnosis and therapeutic intervention with enzyme replacement therapy. Enzyme replacement therapy can stabilize or reduce the progression of the disease. Early therapy may prevent complications of the disease.

Abstract
BACKGROUND Fabry disease is an X-linked lysosomal storage disorder, causing accumulation of globotriaosylceramid in different organs. Glycolipids are activators of different immune cell subsets the resulting inflammation is responsible for organ damage. Pulmonary involvement leads to airway inflammation; however, data on severity, as well as the effect of enzyme replacement therapy on lung function parameters and changes in peripheral immune cell subsets on lung involvement are sparse. METHODS Seven Fabry patients and four carriers underwent detailed clinical examinations screening for pulmonary manifestations. Repetitive measurements were performed on five patients on ERT (average follow-up 5 years). Patients with Fabry disease and control volunteers were included into peripheral blood cell measurements. RESULTS Lung involvement was present in all patients. Symptoms suggestive for lung disease were mild, however, obstructive ventilatory disorder, dominantly affecting small airways accompanied by hyperinflation was demonstrated in all affected patients. ERT resulted in small improvement of FEV1 in most treated patients. Decreased ratio of myeloid DC, Th17 cells while increase in T helper (Th)1 cells, and no change in Th2 and regulatory T (Treg) cells were detected in Fabry patients. CONCLUSIONS Fabry disease results mainly in mild symptoms related to lung involvement, characterized by moderate non-reversible obstructive ventilatory disorder. Stabilization of airway obstruction during follow-up was observed using ERT in most patients, emphasizing the importance of this treatment in respect of pulmonary manifestations. Changes of immune cell subsets in the peripheral blood might play a role in inflammatory process, including small airways in Fabry patient's lung.

Abstract
Fabry disease is a rare, progressive X-linked inborn error of the glycosphingolipid metabolic pathway. Mutations of the GLA gene result in deficiency of the lysosomal enzyme, α-galactosidase A (α-Gal A) with accumulation of glycosphingolipids, particularly globotriaosylceramide (GL3) in the vascular endothelium of various tissues. Accumulation of GL3 eventually leads to life threatening renal, cardiac and cerebrovascular complications typically in the third to fifth decades of life. The first signs and symptoms of classic Fabry disease however appear in childhood but diagnosis is often delayed. The symptoms most commonly experienced in childhood include neuropathic pain, gastrointestinal dysfunction, hyperhidrosis and heat intolerance. Timely diagnosis is important as early treatment with enzyme replacement therapy reduces GL3 accumulation, can stabilize disease progression and potentially prevent irreversible organ damage. Physicians should be familiar with the signs and symptoms of Fabry disease in childhood and be particularly vigilant for unusual or non-specific but recurrent or episodic symptoms.

Abstract
Fabry disease is an X-linked inborn error of glycolipid metabolism caused by deficiency of the human lysosomal enzyme, α-galactosidase A (αGal), leading to strokes, myocardial infarctions, and terminal renal failure, often leading to death in the fourth or fifth decade of life. The enzyme is responsible for the hydrolysis of terminal α-galactoside linkages in various glycolipids. Enzyme replacement therapy (ERT) has been approved for the treatment of Fabry disease, but adverse reactions, including immune reactions, make it desirable to generate improved methods for ERT. One approach to circumvent these adverse reactions is the development of derivatives of the enzyme with more activity per mg. It was previously reported that carboxyl-terminal deletions of 2 to 10 amino acids led to increased activity of about 2 to 6-fold. However, this data was qualitative or semi-quantitative and relied on comparison of the amounts of mRNA present in Northern blots with αGal enzyme activity using a transient expression system in COS-1 cells. Here we follow up on this report by constructing and purifying mutant enzymes with deletions of 2, 4, 6, 8, and 10 C-terminal amino acids (Δ2, Δ4, Δ6, Δ8, Δ10) for unambiguous quantitative enzyme assays. The results reported here show that the kcat/Km approximately doubles with deletions of 2, 4, 6 and 10 amino acids (0.8 to 1.7-fold effect) while a deletion of 8 amino acids decreases the kcat/Km (7.2-fold effect). These results indicate that the mutated enzymes with increased activity constructed here would be expected to have a greater therapeutic effect on a per mg basis, and could therefore reduce the likelihood of adverse infusion related reactions in Fabry patients receiving ERT treatment. These results also illustrate the principle that in vitro mutagenesis can be used to generate αGal derivatives with improved enzyme activity.

[PMID: 25475749 PMCID: PMC4256727 DOI: 10.1186/s12968-014-0099-4] [Citation(s) in RCA: 135] [Impact Index Per Article: 13.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2014] [Accepted: 11/17/2014] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Cardiovascular magnetic resonance (CMR) derived native myocardial T1 is decreased in patients with Fabry disease even before left ventricular hypertrophy (LVH) occurs and may be the first non-invasive measure of myocyte sphingolipid storage. The relationship of native T1 lowering prior to hypertrophy and other candidate early phenotype markers are unknown. Furthermore, the reproducibility of T1 mapping has never been assessed in Fabry disease. METHODS Sixty-three patients, 34 (54%) female, mean age 48±15 years with confirmed (genotyped) Fabry disease underwent CMR, ECG and echocardiographic assessment. LVH was absent in 25 (40%) patients. Native T1 mapping was performed with both Modified Look-Locker Inversion recovery (MOLLI) sequences and a shortened version (ShMOLLI) at 1.5 Tesla. Twenty-one patients underwent a second scan within 24 hours to assess inter-study reproducibility. Results were compared with 63 healthy age and gender-matched volunteers. RESULTS Mean native T1 in Fabry disease (LVH positive), (LVH negative) and healthy volunteers was 853±50 ms, 904±46 ms and 968±32 ms (for all p<0.0001) by ShMOLLI sequences. Native T1 showed high inter-study, intra-observer and inter-observer agreement with intra-class correlation coefficients (ICC) of 0.99, 0.98, 0.97 (ShMOLLI) and 0.98, 0.98, 0.98 (MOLLI). In Fabry disease LVH negative individuals, low native T1 was associated with reduced echocardiographic-based global longitudinal speckle tracking strain (-18±2% vs -22±2%, p=0.001) and early diastolic function impairment (E/E'=7 [6-8] vs 5 [5-6], p=0.028). CONCLUSION Native T1 mapping in Fabry disease is a reproducible technique. T1 reduction prior to the onset of LVH is associated with early diastolic and systolic changes measured by echocardiography.

J Inherit Metab Dis 2014; 37:969-78. [PMID: 24831586 DOI: 10.1007/s10545-014-9717-4] [Citation(s) in RCA: 35] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/28/2013] [Revised: 03/13/2014] [Accepted: 04/10/2014] [Indexed: 11/25/2022]
Abstract
OBJECTIVES To determine the effectiveness of enzyme replacement therapy (ERT) for adults and children with Fabry disease. DESIGN Cohort study including prospective and retrospective clinical data. Age- and gender-adjusted treatment effects were estimated using generalised linear mixed models. Treated patients contributed data before and during treatment and untreated patients contributed natural history data. PARTICIPANTS Consenting adults (N = 289) and children (N = 22) with a confirmed diagnosis of Fabry disease attending a specialist Lysosomal Storage Disorder treatment centre in England. At recruitment 211 adults and seven children were on ERT (range of treatment duration, 0 to 9.7 and 0 to 4.2 years respectively). OUTCOME MEASURES Clinical outcomes chosen to reflect disease progression included left ventricular mass index (LVMI); proteinuria; estimated glomerular filtration rate (eGFR); pain; hearing and transient ischaemic attacks (TIA)/stroke. RESULTS We found evidence of a statistically significant association between time on ERT and a small linear decrease in LVMI (p = 0.01); a reduction in the risk of proteinuria after adjusting for angiotensin-converting enzyme inhibitors and angiotensin receptor blockers (p < 0.001) and a small increase in eGFR in men and women without pre-treatment proteinuria (p = 0.01 and p < 0.001 respectively). The same analyses in children provided no statistically significant results. No associations between time on ERT and pain, risk of needing a hearing aid, or risk of stroke or TIAs, were found. CONCLUSIONS These data provide some further evidence on the long-term effectiveness of ERT in adults with Fabry disease, but evidence of effectiveness could not be demonstrated in children.

Natural course of Fabry disease and the effectiveness of enzyme replacement therapy: a systematic review and meta-analysis: effectiveness of ERT in different disease stages. J Inherit Metab Dis 2014; 37:341-52. [PMID: 24492980 DOI: 10.1007/s10545-014-9677-8] [Citation(s) in RCA: 101] [Impact Index Per Article: 10.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2013] [Revised: 01/07/2014] [Accepted: 01/13/2014] [Indexed: 12/13/2022]
Abstract
OBJECTIVE Current available evidence on long-term effectiveness of enzyme replacement therapy (ERT) for Fabry disease is limited. More insight is needed whether ERT effectiveness differs in patients with and without baseline end-organ damage. DESIGN Through a systematic review, untreated and ERT treated males and females with Fabry disease were compared for main clinical outcomes: renal function, left ventricular mass (LVmass), cerebral white matter lesions (WMLs) and end-organ complications. Through a meta-analysis ERT effectiveness was estimated in different disease stages. DATA EXTRACTION Two reviewers assessed quality of the included studies according to guidelines for prognosis research. Data were synthesized using a random effects meta-analysis. RESULTS Thirty-one studies were systematically reviewed while six studies were included in the meta-analysis. In patients with a GFR > 60 ml/min/1.73 m(2), decline of renal function was similar for treated and untreated patients. Only ERT treated males with a GFR < 60 ml/min/1.73 m(2) had a slower rate of decline in renal function, possibly attributable to anti-proteinuric therapy. Regardless of left ventricular hypertrophy (LVH) at baseline, LVmass remained stable or increased in males despite ERT, however at a slower rate compared to untreated male patients. In ERT treated females with LVH LVmass decreased, and remained stable in females without LVH. WMLs can not be prevented by ERT. Stroke, cardiac and end-stage renal complications develop, though the incidence of new complications seems to be reduced during ERT. CONCLUSION ERT is effective in reducing LVH, but has a limited effect on renal function. Improved treatment options are needed for Fabry disease.

Abstract
BACKGROUND The Canadian Fabry disease initiative (CFDI) tracks outcomes of subjects with Fabry disease treated enzyme replacement therapy (ERT) given to subjects who meet evidence-based treatment guidelines and cardiovascular risk factor modification. METHODS We report 5 year follow-up data on 362 subjects for a composite endpoint (death, neurologic or cardiovascular events, development of end-stage renal disease or sustained increase in serum creatinine of 50% from baseline). RESULTS At enrollment, 86 subjects had previously received ERT (Cohort 1a) and 67 subjects were newly started (Cohort 1b) and randomized to agalsidase alfa or agalsidase beta. 209 subjects did not initially meet ERT criteria (Cohort 1c), 25 of whom met ERT criteria in follow-up and were moved to Cohort 1b (total N=178 ERT treated subjects). Use of supportive therapies such as aspirin (78%), renin-angiotensin blockade (59%), and statins (55%) was common in ERT treated subjects. In Cohort 1a, 32 subjects met the composite endpoint with 8 deaths. In Cohort 1b, 16 subjects met the composite endpoint with 1 death. Cohort 1b had fewer clinical events than Cohort 1a (p=0.039) suggesting that the treatment protocol was effective in targeting subjects at an earlier stage. 19.4% of Cohort 1b subjects on agalsidase alfa and 13.3% on agalsidase beta had a clinical event (p=0.57). 10 Cohort 1c subjects had clinical events, none of which would have been prevented by earlier use of ERT. CONCLUSIONS Cardiovascular risk factor modification and targeted use of ERT reduce the risk of adverse outcomes related to Fabry disease.

Abstract
Fabry disease is an X-linked, lysosomal storage disease caused by the inherited
deficiency of the enzyme α-galactosidase A. The diagnosis is usually
late, with renal, cardiovascular and/or cerebral complications that reduce life
expectancy. Angiokeratomas are asymptomatic lesions present as the initial
manifestation and usually less appreciated. Their detection is important for early
diagnosis and institution of treatment with enzyme replacement therapy, which
prevents late complications reducing morbidity and mortality. We report a case of a
male teenager with acroparestesias and angiokeratomas. Family medical research
discovered that his mother and brother had similar signs and symptoms and that the
three patients had the same mutation in the gene encoding the enzyme, confirming the
diagnosis.

Abstract
A 47-year-old man with stable stage II chronic kidney disease and episodic diarrhea presented with chronic, progressive bilateral lower extremity lymphedema. His mother and 2 brothers had similar acral swelling. Thus, a diagnosis of typical primary familial lymphedema was suspected. Approximately 1 year later, progressive azotemia and proteinuria ensued. A renal biopsy suggested Fabry disease, which was confirmed by enzymatic and genetic testing. In addition, Fabry disease was diagnosed in his mother and 2 male siblings with lower extremity lymphedema. As this case illustrates, Fabry disease is an underappreciated and often unrecognized cause of familial lymphedema.
