Abstract
BACKGROUND Gaucher's disease (GD), a rare condition, represents the most common lysosomal storage disorder. The cardinal manifestations of GD are fatigue, hepatosplenomegaly, anemia, thrombocytopenia, bone pain, and bone infarction, thereby culminating in a marked deterioration of patients' quality of life (QoL). Patient-reported outcomes (PROs) offer valuable insights into the impact of GD on patients' QoL and symptoms. This systematic review aimed to identify and analyze PROs and outcome measures in GD patients. METHODS We systematically searched PubMed, Web of Science Core Collections, EMBASE, SCOPUS, Cochrane Library, PsycINFO, Wan Fang Data, China National Knowledge Infrastructure (CNKI), and the Chinese Biomedical Literature Database (CBM). The methodological quality of the included studies was assessed using a mixed methods assessment tool. RESULTS A total of 33 studies were identified, encompassing 24 distinct patient-reported outcome instruments, with the most frequently employed instrument being the SF-36. The study designs included eighteen cross-sectional studies, seven pre- and post-intervention investigations, three randomized controlled trials, two cohort studies, two qualitative inquiries, and one validation study. These studies explored diverse domains such as the QoL and cardinal symptoms (e.g., fatigue, pain, bleeding, cognition, social relationships, and psychological functioning) in patients with GD. Furthermore, significant attention was directed towards the appraisal of the therapeutic benefits of various interventions in patients with GD. A novel GD-specific instrument has also been developed, which has two applied versions: a 24-item variant for routine clinical monitoring and a 17-item form for use in clinical trials. CONCLUSION PROs have garnered increased attention and concern in the realm of GD. Despite this progress, it is noteworthy that the instruments used to measure PROs in GD are still predominantly generic instruments. While researchers have endeavored to develop and validate a disease-specific instrument, currently the use of this instrument is limited. Owing to several challenges, including the small number of patients, heterogeneity of the disease, and cross-regional discrepancies in study findings, GD poses substantial difficulties in the measurement of QoL and development of instruments. Consequently, patients with GD require more dependable measurement instruments that accurately reflect their QoL, efficacy of treatment, and facilitate healthcare decision-making.

Abstract
We report on a case of a little girl patient diagnosed with Gaucher disease (GD) type 1 in her early childhood and our first experience with enzyme replacement therapy (ERT). She was first diagnosed accidentally with enlarged spleen during a pediatric examination when she was three years old, but the family ignored investigations; she was hospitalized for diagnosis at six years old. The GD was confirmed based on: clinical manifestations of left abdominal flank pain, multiple bruising, general weakness, bone pain, low appetite, failure to thrive <5th percentile, minor hepato- and severe splenomegaly, enlarged submaxillary lymph nodes, associated by anemia with normal platelets; low activity of beta-Glucosidase, two found mutations in GBA gene, Gaucher cells in bone marrow. The ERT was initiated with Imiglucerase (54 UI/kg/2 wks) two years later after diagnosis, avoiding the splenectomy. Subsequently, the platelets showed the first a promising result, gradually increasing their number every 2 weeks and maintaining it in good parameters till the reported moment (2.5 yrs from the start). The hemoglobin level was appreciated within normal ranges 3 months after ERT start and stabilized completely after 6 months. On the other hand, the red blood count normalized within 20 months of applied therapy. The Lyso-GL-1 decreased by 30% after three months of therapy, no antibodies to Imiglucerase were found. The initial spleen volume (1178.19 cm3) decreased by almost 60% in 6 months of ERT, reaching absolutely normal dimensions after 9 months. The ERT with Imiglucerase was tolerated very well by the patient, showing a clear improvement of clinical symptoms after 4-6 months of therapy, hematological picture and splenomegaly solving. Even if the little patient had to come every 2 weeks for infusion, her quality of life improved a lot, being a totally happy child, going to school and having friends. The ERT should be initiated immediately after diagnosis to prevent the multisystem complications.

Abstract
BACKGROUND Neurological forms of Gaucher disease, the inherited disorder of β-Glucosylceramidase caused by bi-allelic variants in GBA1, is a progressive disorder which lacks a disease-modifying therapy. Systemic manifestations of disease are effectively treated with enzyme replacement therapy, however, molecules which cross the blood-brain barrier are still under investigation. Clinical trials of such therapeutics require robust, reproducible clinical endpoints to demonstrate efficacy and clear phenotypic definitions to identify suitable patients for inclusion in trials. The single consistent clinical feature in all patients with neuronopathic disease is the presence of a supranuclear saccadic gaze palsy, in the presence of Gaucher disease this finding serves as diagnostic of 'type 3' Gaucher disease. METHODS We undertook a study to evaluate saccadic eye movements in Gaucher patients and to assess the role of the EyeSeeCam in measuring saccades. The EyeSeeCam is a video-oculography device which was used to run a protocol of saccade measures. We studied 39 patients with non-neurological Gaucher disease (type 1), 21 patients with type 3 (neurological) disease and a series of 35 healthy controls. Mean saccade parameters were compared across disease subgroups. RESULTS We confirmed the saccadic abnormality in patients with type 3 Gaucher disease and identified an unexpected subgroup of patients with type 1 Gaucher disease who demonstrated significant saccade parameter abnormalities. These patients also showed subtle neurological findings and shared a GBA1 variant. CONCLUSIONS This striking novel finding of a potentially attenuated type 3 Gaucher phenotype associated with a specific GBA1 variant and detectable saccadic abnormality prompts review of current disease classification. Further, this finding highlights the broad spectrum of neuronopathic Gaucher phenotypes relevant when designing inclusion criteria for clinical trials.

Abstract
BACKGROUND Gaucher disease is a rare hereditary glycolipid storage disease. One of the rare complications is neurodeficits due to vertebral involvement. CASE PRESENTATION An 18-year-old female patient presented to the outpatient clinic with cauda equina syndrome due to sacral involvement of type 1 GD. Bilateral laminectomy via posterior approach without posterior stabilization was performed. CONCLUSION Maximum excision of the mass avoiding destabilization of the spinal column can provide long-term vertebral stability and improvement in neurodeficits.

Abstract
BACKGROUND Gaucher disease is an autosomal recessive disorder resulting from the accumulation of glucocerebroside in the cells of the macrophage-monocyte system caused by deficiency in lysosomal glucocerebrosidase. Intravenously administered enzyme replacement therapy is the first-line therapy for Gaucher disease type 1 and substrate reduction therapy represents an alternative oral treatment. Here is a rare case report of Gaucher disease in South China. CASE PRESENTATION Our patient was a 15-year-old Han Chinese boy presenting with fever, edema, and gradually increasing abdominal girth. A physical examination revealed obvious hypoevolutism and hepatomegaly, and laboratory tests and imaging examinations showed severe pulmonary interstitial fibrosis, infection, and moderate anemia. A final diagnosis of Gaucher disease was confirmed after examining the splenic pathological section derived from a splenectomy performed 6 years ago. His recovery improved after receiving anti-infection, diuresis, blood transfusion, and hepatoprotection and so on. However, enzyme replacement therapy was not adopted by our patient because his family could not afford it. CONCLUSION A rare case of Gaucher disease is reported here to emphasize the importance of early recognition by clinical manifestation and histological findings. Gaucher disease should be considered in the differential diagnosis of children with unexplained symptoms of multiple systems.

Abstract
Background Gaucher disease is one of the most common lipid-storage disorders, affecting approximately 1 in 75,000 births. Enzyme replacement therapy with recombinant glucocerebrosidase is currently considered the first-line treatment choice for patients with symptomatic Gaucher disease type 1. Oral substrate reduction therapy is generally considered a second-line treatment option for adult patients with mild to moderate Gaucher disease type 1 who are unable or unwilling to receive lifelong intravenous enzyme infusions. The efficacy and safety of the oral substrate reduction therapy miglustat (Zavesca®) in patients with Gaucher disease type 1 have been established in both short-term clinical trials and long-term, open-label extension studies. Published data indicate that miglustat can be used as maintenance therapy in patients with stable Gaucher disease type 1 switched from previous enzyme replacement therapy. Case presentation We report a case of a 44-year-old Caucasian man with Gaucher disease type 1 who was initially treated with enzyme replacement therapy but, owing to repeated cutaneous allergic reactions, had to be switched to miglustat after several attempts with enzyme replacement therapy. Despite many attempts, desensitization treatment did not result in improved toleration of imiglucerase infusions, and the patient became unwilling to continue with any intravenous enzyme replacement therapy. He subsequently agreed to switch to oral substrate reduction therapy with miglustat 100 mg twice daily titrated up to 100 mg three times daily over a short period. Long-term miglustat treatment maintained both hemoglobin and platelet levels within acceptable ranges over 8 years. The patient’s spleen volume decreased, his plasma chitotriosidase levels stayed at reduced levels, and his bone mineral density findings have remained stable throughout follow-up. The patient’s quality of life has remained satisfactory. Miglustat showed good gastrointestinal tolerability in this patient, and no adverse events have been reported. Conclusions Oral miglustat therapy proved to be a valid alternative treatment to intravenous enzyme replacement therapy for long-term maintenance in this patient with Gaucher disease type 1, who showed persistent allergic intolerance to imiglucerase infusions. This report exemplifies the type of patient with Gaucher disease type 1 who can benefit from switching from enzyme replacement therapy to substrate reduction therapy.

Abstract
We aim to describe an 8-year-old boy with an unusual clinical presentation of Gaucher disease (GD). Gaucher disease is a progressive lysosomal storage disorder due to deficiency of the specific enzyme glucocerebrosidase with varying clinical features, but often involving the monocytes-macrophages systems. This child ran a progressive course with a devastating outcome. Three distinct GD subtypes have been described with varying clinical features based on the presence or absence of neurologic involvement. Gaucher disease diagnosis is obtained via: enzyme activity assay, gene mutation study, bone marrow aspiration in addition to multiple other tests that have been successfully used in diagnosis of cases of GD. Treatment modalities include enzyme replacement treatment, substrate reduction therapy, bone marrow transplantation, blood transfusion, and surgery are available management modalities for GD. Gaucher disease is a chronic disease requiring a multidisciplinary team approach with regular follow up with multiple subspecialties.

Abstract
Hemoglobin (Hb) E mutation is common in north-east part of our country. The natural history of Hb E thalassemia is highly variable. The phenotype, for patients with similar mutations, can range from asymptomatic to transfusion dependent. Our patient presented at 2 years of age with failure to thrive and hepatosplenomegaly. Routine work up revealed microcytic, hypochromic red blood cells. Hb E homozygous was indicated on electrophoresis and hemoglobin HPLC. Evaluation of parents revealed Haemoglobin E trait in both. Therapeutic splenectomy revealed Gaucher-like cells. β-Glucocerebrosidase levels were low. Presence of Gaucher-like cells with normal β-glucocerebrosidase (pseudo-Gaucher cells) are known in leukemia, multiple myeloma, thalassemia and mycobacterial infections. Co-existence of Gaucher's disease with Hb E mutation is not reported to the best of our knowledge.

Abstract
Gaucher's disease is not commonly considered in the differential diagnosis of adult patients with hepatosplenomegaly and increased serum ACE. A 19-year-old girl presented with recurrent epigastric and left hypochondrial pain over a period of 9 years, associated with episodes of nausea and diarrhoea. She was extensively investigated and found to have splenomegaly and raised serum ACE. A screen for haematological disorders was negative. She reported an insect bite during an overseas holiday preceding her symptoms. She was therefore also screened for infectious causes of hepatosplenomegaly but without success. Later on in life, she reported joint pain and discomfort. Sarcoidosis was thought to be the putative cause on more than one occasion. However, the presence of splenomegaly and her relatively young age, led the rheumatologist to the correct diagnosis.

Abstract
Gaucher's disease is caused by a deficiency of glucocerebrosidase (GBA) and results in the accumulation of glucocerebroside within macrophages. We report on a 33(+2) gestational week premature infant whose family history was significant for a previously undiagnosed premature sibling with similar clinical features, including severe hydrops fetalis, hepatosplenomegaly, skin lesions at birth followed by death. The diagnosis of Gaucher's disease type 2 in the present case was based on postmortem pathological findings and a subsequent gene analysis that indicated a heterozygous condition for the novel deletion mutation at GBA cDNA nucleotide position 630 resulting in the frameshift (Pro171fsX21) in exon 6 and a G→A transition mutation at GBA cDNA nucleotide position 887 (Arg257Gln) in exon 7.

Abstract
Gaucher's disease (GD) occurs because of deficiency of the enzyme beta-glucocerebrosidase that results in accumulation of this glycolipid compound in the cells of the macrophage-monocyte system. There are 3 types: type 1 is non-neuronopathic with primarily visceral signs and symptoms which range tremendously in severity; infantile-onset type 2 and later-onset type 3 involve the central nervous system. More than 300 mutations have been described in the gene, partially explaining phenotypic heterogeneity. Commercialization in 1991 of the first enzyme replacement therapy, alglucerase, resulted in a revolution in the management of patients with symptomatic GD (i.e., by improving the hematological and visceral signs and symptoms). Within the first 5 years of alglucerase, its safety and efficacy in improving hemoglobin levels and platelet counts, and in reducing splenic and hepatic enlargement were confirmed albeit recognizing its inability to impact neurological symptoms and signs because of its large molecular size. Recombinant imiglucerase soon replaced alglucerase as the standard of care for GD. The therapeutic targets recently defined as treatment goals were: normalization of cell counts; reduction of liver and spleen volume; elimination of the infiltration in the bone marrow to prevent the complications, and improvement in surrogate biomarkers.

Abstract
INTRODUCTION The aim of this work is to assess the usefulness of apparent diffusion coefficient (ADC) value of the brain for diagnosis of patients with Gaucher's disease type II and type III. METHODS Prospective study was conducted upon 13 patients (nine boys and four girls aged 8 months-14 years: mean 6.1 years) with Gaucher's disease type II and III and for age-matched control group (n = 13). Diffusion-weighted magnetic resonance imaging using a single-shot echo-planar imaging with a diffusion-weighted factor b of 0, 500, and 1,000 s/mm(2) was done for all patients and volunteers. The ADC value was calculated in ten regions of the brain parenchyma and correlated with genotyping. RESULTS There was significantly lower ADC value of the cortical frontal (P = 0.003), cortical temporal (P = 0.04), frontal subcortical white matter (P = 0.02), corticospinal tract (P = 0.001), cerebellum (P = 0.001), medulla (P = 0.002), and midbrain (P = 0.02) between patients and volunteers. There was significant difference in the ADC value of the frontal and temporal gray matter (P = 0.04 and 0.05, respectively) between patients with heterozygous and homozygous gene mutation. CONCLUSION We concluded that ADC value is a new promising quantitative imaging parameter that can be used for the detection of brain abnormalities in patients with Gaucher's disease type II and type III and has a correlation with genotyping.

Abstract
Gaucher disease (GD) is caused by the reduced activity of a lysosomal enzyme, glucocerebrosidase, leading to the accumulation of glucocerebroside (GC). The relatively high prevalence of this disease within an ethnic group is believed to reflect a selective advantage. Treatment with enzyme replacement therapy (ERT) is safe and effective in ameliorating the primary symptoms of the disease, yet there have been reports that some patients on ERT have developed type 2 diabetes or metabolic syndrome, malignancies and central nervous system disorders. A series of animal studies suggest that these complications may be related to the reduction of GC levels by the enzyme administered. GC has been shown to have an immunomodulatory effect through the promotion of dendritic cells, natural killer T cells, and regulatory T cells. The break down of GC to ceramide can underline part of these findings. Clinical trials suggested a beneficial effect of GC in type 2 diabetes or nonalcoholic steatohepatitis. This review of the data from animal models and humans proposes that the increased level of GC may provide an evolutionary advantage for patients with GD. Indirectly, these data support treating symptomatic patients with mild/moderate GD with low-dose ERT and re-evaluating the use of ERT in asymptomatic patients.

Abstract
The role of heritable thrombophilic risk factors in the pathogenesis of the Perthes' disease is controversial. The clinical and radiological findings of Perthes' disease may be indistinguishable from those of Gaucher's disease, and the most common Jewish N370S Gaucher mutation is threefold greater in patients with Perthes' disease. Familial osteonecrosis of the femoral head is associated with variant mutations of collagen type II (COL2A1 mutations). We therefore studied the potential role of genetic thrombophilia and the Gaucher and COL2A1 mutations in children with Perthes' disease. Genomic DNA of 119 children with radiologically-confirmed Perthes' disease diagnosed between 1986 and 2005 was analysed for the thrombophilic polymorphisms Factor V Leiden, 677T-MTHFR and FIIG20210A. The results were compared with those of a group of 276 children without Perthes' disease. DNA was also analysed for the Gaucher mutations N370S, G insertion (84GG), L444P, Intron 2 (IVS2+1G>A) and R496H. Enzymic assays confirmed the Gaucher disease status. Collagen (COL2A1) mutations of the 12q13 gene were also analysed. The prevalence of thrombophilic markers was similar among the 119 patients with Perthes' disease and the 276 control subjects. The prevalence of the Gaucher mutation was consistent with Israeli population carriership data and did not confirm an earlier-claimed association with Perthes' disease. All 199 patients were negative for the studied COL2A1 mutations. We found no genetic association between Perthes' disease and either Gaucher's disease or COL2A1 mutations or increased genetic thrombophilia among our patients compared with the control group. A systematic review of case-control studies suggested that there was a positive association between Perthes' disease and Factor V Leiden. The impact of this association upon the disease, although not consistent across the studies, remains unclear.

Abstract
beta-Glycosphingolipids have emerged as a family of potential ligands for natural killer T (NKT)-regulatory lymphocytes. This subset of regulatory lymphocytes has been implicated in the regulation of autoimmune processes. The major histocompatibility complex (MHC) Class I-like CD1d glycoprotein is a member of the CD1 family of antigen-presenting molecules and is responsible for selection of NKT cells. beta-Glycolipids have been shown to alter immune responses in the opposing settings of autoimmune diseases or cancer. In this review, we discuss the potential use of beta-glycoshpingolipids for NKT-based immunotherapy.

Abstract
We present a brief review of Gaucher disease, the most common lysosomal storage disease. Gaucher disease is a rare autosomal recessive disorder characterized by defective function of the catabolic enzyme beta-glucocerebrosidase, leading to an accumulation of its substrate, glucocerebroside, in the mononuclear phagocyte system, especially histiocytes in the spleen, lymph nodes, and bone marrow; Kupffer cells in the liver; osteoclasts in bone; microglia in the central nervous system; alveolar macrophages in the lungs; and histiocytes in the gastrointestinal tracts, genitourinary tracts, and the peritoneum. Clinical signs and symptoms include neurologic dysfunctions, bone infarcts and malformations, hepatosplenomegaly and hypersplenism leading to anemia, neutropenia, and thrombocytopenia. Enzyme replacement therapy with recombinant glucocerebrosidase is the mainstay of treatment for Gaucher disease, which became the first successfully managed lipid storage disease. Future treatments may include oral enzyme replacement and/or gene therapy interventions.

Abstract
BACKGROUND Gaucher disease (GD) is caused by deficiency of acid beta-glucocerebrosidase and is the most common lysosomal storage disease. Patients may have massive hepatosplenomegaly, severe bone disease, and, occasionally, pulmonary or neurological involvement. Although other storage diseases, such as Fabry disease, frequently affect the kidneys, reports of renal abnormalities in patients with GD are limited to case reports. Our aim was to perform a comprehensive evaluation of renal function in patients with GD. METHODS Evaluation was performed at routine clinic visits and included blood pressure recording and renal ultrasound. Serum chemistries, urinalysis, urine electrolytes, total protein, and tubular proteinuria were assessed, and estimated glomerular filtration rate (GFR) was calculated. RESULTS One hundred sixty-one patients underwent evaluation, including 26 children. GFR was significantly greater in patients with GD than in age- and sex-matched healthy controls (P = 0.01 in men, P < 0.001 in women, P = 0.003 in children). Subgroups of patients with markers of more severe disease had a greater GFR than other patients. No patient had decreased renal function. Significant proteinuria was found only in patients with such comorbidities as diabetes mellitus or multiple myeloma. No evidence of renal tubular abnormalities was found, and kidney sonographic appearance and size were normal. CONCLUSION Despite the multiorgan nature of the disease, a systematic evaluation did not find renal abnormalities in patients with GD. Glomerular hyperfiltration was observed in a proportion of patients, particularly those with markers of more severe disease. This phenomenon does not seem to be associated with a subsequent decline in renal function.

Abstract
The authors report a rare case of type-1 Gaucher disease with neurological and haematological involvement. The first onset was epilepsy, the diagnosis of GD1 was then confirmed and the patient experienced parkinsonism. The biological analysis revealed monoclonal gammapathy and factor-II mutation. The patient's condition worsened due to cauda equina syndrome. Magnetic resonance imaging and surgery revealed an intra-thecal sacral cyst which, to our knowledge, has not been reported previously; therefore, when confronted with the fractures commonly observed in GD1, other unusual causes of spinal cord and root compression should not be overlooked.

Abstract
Gaucher disease, the most prevalent lysosomal storage disorder, is inherited as an autosomal recessive condition. The gold standard for diagnosis is decreased acid beta-glucosidase activity in the lymphocytes or fibroblasts; molecular analysis of mutations allows for some prognostication of disease severity. Prenatal diagnosis and carrier testing for at-risk families are currently available. There is tremendous phenotypic heterogeneity in the non-neuronopathic form (type I), ranging from clinically asymptomatic to massive hepatomegaly, hypersplenism, growth retardation in children and extensive involvement of bone and lungs. Presence on one allele of the most common mutation, N370S, which is the most prevalent among Ashkenazi Jews for whom there is a predilection for Gaucher disease, is protective of neurological involvement. Some mutations, such as 84GG and IVS2+1, are associated with more severe disease manifestations when appearing as compound heterozygotes with N370S, but when occurring in the homozygous state are not compatible with life. Other mutations, such as L444P, are associated with severe non-neurological disease when occurring as compound heterozygotes with N370S, but when occurring in the homozygous state may be predictive of neurological disease of either acute (type II) or subacute (type III) forms. In the past decade, enzyme replacement therapy has become available which has resulted in a reduction in liver and spleen volume and consequently improved anemia and thrombocytopenia in most patients. It has also engendered catch-up growth in many children, induced improvement in lung involvement secondary to Gaucher disease, and to some extent ameliorated episodes of bone pain. By virtue of treatment, many children who may have been severely affected no longer need to undergo splenectomy to treat hypersplenism, and therefore they are not at risk of bone involvement consequent to the loss of the preferred reservoir for lipid-laden 'Gaucher cells'. However, enzyme treatment is ineffective in reversing neurological signs, requires a lifelong commitment to intravenous infusions, thereby reducing quality of life, and is relatively expensive for many national health schemes. Hence, alternative forms of treatment, such as substrate balance, are being explored. Symptomatic management, including orthopedic surgery, pain relief for bone pain and even splenectomy, still has importance for patients with Gaucher disease. In addition, there is the potential for bone marrow transplantation and, in the future, gene therapy to be curative, particularly for patients with the neuronopathic forms.

Abstract
Miglustat is an orally administered ceramide glucosyltransferase inhibitor which prevents the lysosomal accumulation of glucocerebroside that occurs in patients with Gaucher's disease. In noncomparative trials in patients with type 1 Gaucher's disease, miglustat (50 or 100mg three times daily) for 6-12 months significantly reduced baseline liver and spleen volumes. At both 6 and 12 months, the reductions in organ volumes were greater with the higher dosage. Miglustat 50 or 100mg three times daily for 6-12 months had no significant effect on haemoglobin concentrations. Baseline platelet counts were not significantly improved by either dosage at 6 months, although the higher dosage significantly increased platelet counts at 12 months. In an open extension phase, patients continued to show further reductions in organ volume as well as significant improvements in haematological parameters at 24 and 36 months. black triangle In a 6-month randomised study in patients with type 1 Gaucher's disease who had previously received long-term enzyme replacement therapy (ERT), liver volume reduction was greater with miglustat plus ERT than with ERT alone. Diarrhoea and weight loss were the most frequent adverse events associated with miglustat therapy. Fine tremor has been reported in approximately 30% of miglustat-treated patients.

Abstract
Fine needle aspiration (FNA) is a diagnostic tool whose inexpensiveness, simplicity and innocuousness have led it to be increasingly accepted in daily medical practice. This method, which is useful for the study of lesions that are accessible by radiological exploration or palpation, provides information about the cytological aspects of punctured lesions. Sometimes, such information can be extended to the histological area through study of cell blocks, true microbiopsies, which are of great diagnostic use. This was the technique used in the case described in the present report.

Abstract
Anderson-Fabry disease (AFD) is a lysosomal storage disorder (LSD) due to alpha-galactosidase A (alpha-Gal A) deficiency and the resultant accumulation of incompletely metabolised glycosphingolipids (GSLs), primarily globotriosylceramide (Gb(3)), within various tissues. It is an X-linked multisystem disorder characterised by progressive renal insufficiency, with added morbidity from cardio- and cerebrovascular involvement, and associated with significant impact on quality of life and diminished lifespan. The disease manifests primarily in hemizygous males; however, there is increasing recognition that heterozygous (carrier) females may also develop disease-related complications, although onset among affected women may be delayed. Until recently, treatment has been limited to symptomatic management of pain and other measures to alleviate the problems associated with end-stage complications from renal, cardiac and nervous system involvement. The availability of the recombinant enzyme offers the potential of a safe and effective targeted treatment approach. At the moment, two distinct enzyme formulations are approved in Europe (and in other countries) and both continue to undergo FDA evaluation in the US. Increasing knowledge of the natural history of AFD and greater experience with enzyme therapy should enable optimal patient care. The relative rarity and complexity of AFD necessitates a multi-disciplinary team approach that may be facilitated by a centralised registry.
