Abstract
Background Fabry disease (FD) is a rare inherited lysosomal storage disorder caused by the deficiency of the enzyme alpha-galactosidase A. This deficiency leads to an accumulation of glycosphingolipids leading to progressive and multisystemic disease, including renal, cardiac, and neurological damages. FD may also have neuro-otological and visual impairments, which can generate postural control alterations, inner ear, and vision being involved in this function. This study aimed to evaluate the impact of FD on postural control. Methods In total, fourteen adult patients (8 men/6 women, mean age = 37.6 ± 11.4 years) and two children (mean age = 11 years) with FD and 19 healthy adults (12 men/7 women, mean age = 36.5 ± 16.9 years) and two healthy children (mean age = 10.5 years) took part in this study. Postural control was evaluated by a sensory organization test combining three visual situations (eyes open, eyes closed, and sway referenced visual surround motion) with two platform situations (stable platform and sway referenced platform motion), aiming to calculate a composite equilibrium score (CES), a high score being representative of good postural control. Somatosensory (RSOM), visual (RVIS), and vestibular (RVEST) contributions to postural control were calculated, a low score reflecting a poor use of the indicated sensory input. Results The CES was lower in adult patients with FD compared with the healthy subjects (p < 0.001). RVIS (p = 0.001) and RVEST (p = 0.003) were lower in patients with FD compared with the control group, whereas no difference in RSOM was observed. Conclusion Inner ear and visual pathologies associated with the central nervous system impairments are factors of postural control impairments. Physical activities, which can also be rehabilitative, by maintaining or increasing the weight of proprioception, may help diminish dependency on altered sensorial inputs.

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
ABSTRACT Severe neuropathic pain is a hallmark of Fabry disease, a genetic disorder caused by a deficiency in lysosomal α-galactosidase A. Pain experienced by these patients significantly impacts their quality of life and ability to perform everyday tasks. Patients with Fabry disease suffer from peripheral neuropathy, sensory abnormalities, acute pain crises, and lifelong ongoing pain. Although treatment of pain through medication and enzyme replacement therapy exists, pain persists in many of these patients. Some has been learned in the past decades regarding clinical manifestations of pain in Fabry disease and the pathological effects of α-galactosidase A insufficiency in neurons. Still, it is unclear how pain and sensory abnormalities arise in patients with Fabry disease and how these can be targeted with therapeutics. Our knowledge is limited in part due to the lack of adequate preclinical models to study the disease. This review will detail the types of pain, sensory abnormalities, influence of demographics on pain, and current strategies to treat pain experienced by patients with Fabry disease. In addition, we discuss the current knowledge of Fabry pain pathogenesis and which aspects of the disease preclinical models accurately recapitulate. Understanding the commonalities and divergences between humans and preclinical models can be used to further interrogate mechanisms causing the pain and sensory abnormalities as well as advance development of the next generation of therapeutics to treat pain in patients with Fabry disease.

Abstract
BACKGROUND Fabry disease (FD) is a hereditary X-linked metabolic storage disorder characterized by deficient or absent lysosomal α-galactosidase A (α-Gal A) activity. This deficiency causes progressive accumulation of glycosphingolipids, primarily globotriaosylceramide (Gb3), in nearly all organ systems. Gastrointestinal (GI) symptoms can be very debilitating and are among the most frequent and earliest of the disease. As the pathophysiology of these symptoms is poorly understood, we carried out a morphological and molecular characterization of the GI tract in α-Gal A knockout mice colon in order to reveal the underlying mechanisms. METHODS Here, we performed the first morphological and biomolecular characterization of the colon wall structure in the GI tract of the α-Gal A knock-out mouse (α-Gal A -/0), a murine model of FD. KEY RESULTS Our data show a greater thickness of the gastrointestinal wall in α-Gal A (-/0) mice due to enlarged myenteric plexus' ganglia. This change is paralleled by a marked Gb3 accumulation in the gastrointestinal wall and a decreased and scattered pattern of mucosal nerve fibers. CONCLUSIONS AND INFERENCES The observed alterations are likely to be a leading cause of gut motor dysfunctions experienced by FD patients and imply that the α-Gal A (-/0) male mouse represents a reliable model for translational studies on enteropathic pain and GI symptoms in FD.

Abstract
Fabry disease is an X-linked lysosomal storage disorder with involvement of the nervous system. Accumulation of glycosphingolipids within peripheral nerves and/or dorsal root ganglia results in pain due to small-fiber neuropathy, which affects the majority of patients already in early childhood. The α-galactosidase A deficient mouse proved to be an adequate model for Fabry disease, as it shares many symptoms including altered temperature sensitivity and pain perception. To characterize the signatures of gene expression that might underlie Fabry disease-associated sensory deficits and pain, we performed one-color based hybridization microarray expression profiling of DRG explants from adult α-galactosidase A deficient mice and age-matched wildtype controls. Protein-protein interaction (PPI) and pathway analyses were performed for differentially regulated mRNAs. We found 812 differentially expressed genes between adult α-galactosidase A deficient mice and age-matched wildtype controls, 506 of them being upregulated, and 306 being downregulated. Among the enriched pathways and processes, the disease-specific pathways “lysosome” and “ceramide metabolic process” were identified, enhancing reliability of the current analysis. Novel pathways that we identified include “G-protein coupled receptor signaling” and “retrograde transport” for the upregulated genes. From the analysis of downregulated genes, immune-related pathways, autoimmune, and infection pathways emerged. The current analysis is the first to present a differential gene expression profile of DRGs from α-galactosidase A deficient mice, thereby providing knowledge on possible mechanisms underlying neuropathic pain related symptoms in Fabry patients. Therefore, the presented data provide new insights into the development of the pain phenotype and might lead to new treatment strategies.

Abstract
BACKGROUND Peripheral nerve system (PNS) involvement is common in Fabry's disease (FD), predominantly affecting the small nerve fibers that are difficult to investigate with conventional electrophysiological methods. PATIENTS AND METHODS Eighteen patients followed for Fabry's disease underwent a prospective series of electroneurophysiological explorations, including a study of the cardiac parasympathetic autonomic nervous system (ANS) and electrochemical skin conductance (ESC) tests. Data were compared with those obtained in 18 matched healthy controls. RESULTS All patients had at least one clinical sign suggestive of neuropathy: 16 reported an acrosyndrome and 12 had dyshidrosis. Cold hypoesthesia was found in 15 patients and heat hypoesthesia in 13. Electroneurophysiological investigations and study of the cardiac parasympathetic ANS were normal in all patients. The ESC was significantly lower in FD patients compared with controls. CONCLUSION PNS involvement is common in FD and should be suspected in patients exhibiting an acrosyndrome, dyshidrosis and/or cold hypoesthesia. Conventional electrophysiological investigations are normal. New techniques, such as ESC, provide early diagnosis of small fiber involvement that currently requires more sophisticated tests difficult to apply in routine practice.

Abstract
The evaluation and management of childhood pain syndromes of neuromuscular origin have distinct challenges, as the patterns of disease presentation and the ability of a child to describe symptoms may differ from that of an adult. Advances in scientific and clinical knowledge are leading to significant progress in the care of affected children. The genetic origins of Fabry disease and the inherited form of erythromelalgia are better understood. The increasing interest in neuroimmunology among pediatric neurologists has led to more sophisticated diagnostic and therapeutic approaches. Treatment protocols for complex regional pain syndrome have become more standardized. In addition, investigations continue into potential new interventions for metabolic muscle diseases such as McArdle disease and carnitine palmitoyl transferase deficiency type II. In the years to come, children with pain of neuromuscular origin will have access to more precise diagnostic tools and novel therapies that would alleviate this particularly distressing category of disease.

Abstract
BACKGROUND Peripheral neuropathy in Fabry disease predominantly involves small nerve fibers. Recently, enzyme replacement therapy (ERT) with recombinant human alpha-galactosidase A has become available. OBJECTIVE To evaluate whether ERT improves Fabry neuropathy. METHODS In 22 Fabry patients (age 27.9 +/- 8.0 years) undergoing ERT with recombinant human alpha-galactosidase A (agalsidase beta) for 18 (n = 11) or 23 (n = 11) months and in 25 control subjects (age 29.0 +/- 10.4 years), the authors performed quantitative sensory testing using the 4, 2, and 1 stepping algorithm (CASE IV). Detection thresholds of vibration (VDT) on the first toe were assessed; cold detection thresholds (CDT), heat-pain onset (HP 0.5), and intermediate heat-pain (HP 5.0) assessments were made on the dorsum of the feet. Patient values above mean + 2.5 SD of control values were considered abnormal. RESULTS Before ERT, VDT, CDT, HP 0.5, and HP 5.0 were higher in patients than control subjects (p < 0.05). Following ERT, patients developed lower thresholds than prior to ERT for VDT (15.5 +/- 3.5 vs 14.3 +/- 4.1; p < 0.05), HP 0.5 (22.3 +/- 6.7 vs 19.4 +/- 1.3; p < 0.01), and HP 5.0 (27.3 +/- 5.6 vs 22.5 +/- 2.3; p < 0.01). Moreover, fewer patients had abnormal results of VDT (2 vs 4), CDT (7 vs 12), HP 0.5 (0 vs 9), and HP 5.0 (4 vs 20) after than before ERT. CONCLUSIONS ERT therapy with agalsidase beta significantly improves function of C-, Adelta-, and Abeta-nerve fibers and intradermal vibration receptors in Fabry neuropathy. Lack of recovery in some patients with abnormal cold or heat-pain perception suggests the need for early ERT, prior to irreversible nerve fiber loss.

Abstract
We prospectively performed neurophysiologic studies in nine Fabry's Disease (FD) patients (8 male and 1 female) in order to describe the results of nerve conduction studies (NCS) and electromyography (EMG) and to verify whether the sympathetic skin response (SSR) is impaired in these patients. The investigation protocol included SSR, sensory and motor NCS and EMG. SSR was performed not only in FD patients, but also in 18 normal controls. All FD patients had normal nerve conduction studies and electromyography. SSR was present in all controls with a mean amplitude of 1453.6+/-682.3 microV. However, the SSR was absent in six and lower than 500 microV in the remaining FD patients. All patients had normal sensory and motor NCS and EMG. SSR, on the other hand, was significantly altered in all patients and this test could, therefore, be useful in the diagnostic evaluation of FD patients.

Abstract
Supportive care, symptomatic treatment, and patient education should be provided for patients with inherited or acquired polyneuropathies. In addition, specific treatment is available for many of the acquired polyneuropathies. Genetic counseling is valuable for many patients with inherited polyneuropathies, but only rarely is specific treatment an option for these patients. However, specific treatments are available for many of the rare and devastating systemic disorders associated with polyneuropathies. Thus, clinicians must promptly diagnose these inherited disorders so that specific treatment may be initiated. The clinical features of these rare inherited disorders are emphasized.

Abstract
BACKGROUND Anticipating the prospect of specific treatment, we studied a large group of Australians with Fabry's disease. AIMS We aimed to: (i) document the clinical features of Fabry's disease in Australian patients, (ii) test the hypothesis that clinical features vary with specific mutation and blood group and (iii) assess small-fibre peripheral nerve function. METHODS A questionnaire was forwarded to all Australian patients known to us. Patients were invited to attend for clinical, renal cardiac, ophthalmological and neurological assessment. RESULTS Sixty-seven patients (29 men and 38 women) from 18 families participated. Diagnosis in index cases was delayed by > or = 10 years in nearly all families. Common clinical features are: (i) episodic acroparaesthesia (100% of hemizygotes; 53% of heterozygotes), (ii) anhydrosis (93%; 1%), (iii) characteristic rash (93%; 13%), (iv) renal disease (69%; 21%), (v) ischaemic heart disease (28%; 26%), (vi) palpitations (62%; 29%), (vii) mitral valve murmurs (37%; 23%) and (viii) premature cerebrovascular disease (31%; 5%). Ophthalmic findings of cornea verticillata (96%; 76%) and anterior cataract (48%; 14%) were common. Findings were variable within and between families. In women, anhydrosis reliably predicts the presence of significant Fabry's renal disease. Small nerve fibre testing using quantitative sensory testing was clearly abnormal in 95% of male patients, and in those female patients with paraesthesiae. CONCLUSIONS Symptoms of anhydrosis, acroparaesthesiae, rash and renal disease suggest diagnosis of Fabry's. Women are commonly symptomatic, and the advent of therapy highlights the practical advantage of earlier diagnosis.

Abstract
Fabry disease is an X-linked recessive disease with a reduction of lysosomal alpha galactosidase A and consecutive storage of glycolipids e.g., in the brain, kidney, skin, and nerve fibers. Cardinal neurologic findings are hypohidrosis, painful episodes, and peripheral neuropathy. So far, the neurophysiological findings regarding the extent of large and small fiber dysfunction are contradictory. This study evaluated large and small nerve fiber function in a homogeneous group of Fabry patients. In 24 of 30 Fabry patients with creatinine below 194.7 mmol/L the authors assessed median, ulnar, and peroneal motor conduction velocity (MCV) and median, ulnar, and sural sensory conduction velocity (SCV) nerve conduction to study the function of thickly myelinated nerve fibers. In addition, the authors studied sympathetic skin responses (SSR) at both hands and feet in 24 patients. To evaluate A beta nerve fiber function, the authors determined vibratory detection thresholds (VDT) at the first toe in 30 patients. Function of A delta and C fibers was assessed by quantitative sensory testing of cold detection threshold (CDT) and heat-pain detection thresholds (HPDT). Nerve conduction studies showed significantly decreased amplitudes of MCVs and SCVs in Fabry patients as compared to controls. However, individual results of MCV and SCV studies were only mildly impaired. SSRs were present in all tested patients but SSR amplitudes were significantly decreased in Fabry patients in comparison to controls. VDT, CDT, and HPDT were significantly elevated in Fabry patients as compared to controls. However, only six patients had pathologic VDT, 19 had increased CDT, and 25 had elevated HPDT at a high level of stimulation. In Fabry patients, small fiber dysfunction is more prominent than large fiber dysfunction, confirming previous findings of sural nerve biopsies. The results suggest a higher vulnerability of small-diameter nerve fibers than of the thickly myelinated fibers.

Abstract
Fabry's disease is commonly associated with a painful, debilitating neuropathy. Characterization of the physiological abnormalities is an important step in evaluating response to specific therapies. Twenty-two patients with Fabry's disease, and with relatively preserved renal function, underwent conventional and near-nerve conduction studies, electromyography, sympathetic skin responses, and quantitative sensory testing (QST). Nerve conduction studies were mostly normal except for an increased frequency of median nerve entrapment at the wrist in 6 (27%) patients. Sympathetic skin responses were preserved in 19 of 20 (95%) of the patients. The QST showed increased or immeasurable cold and warm detection thresholds in patients, significantly different from controls (n = 28) in the hand (P < 0.001, P = 0.04, respectively) and foot (P < 0.001 for both). Cold thresholds were more often abnormal than were warm thresholds. Vibration thresholds were normal in the feet and, in some patients, elevated in the hand only, probably due to frequent median nerve entrapment at the wrist. Our findings suggest that the neuropathy of Fabry's disease is characterized by an increased prevalence of median nerve entrapment at the wrist and by thermal afferent fiber dysfunction in a length-dependent fashion, with greater impairment of cold than warm sensation.

Abstract
We assessed the cutaneous silent period (CSP) in 24 patients with Fabry disease with small-fiber sensory neuropathy and 12 normal subjects to test the hypothesis that small-diameter afferents are responsible for producing the CSP. Sensory nerve conduction studies and quantitative sensory testing for cold and vibration detection thresholds were also measured. Overall, Fabry patients had impaired thermal, but not vibration, detection thresholds, with greatest impairment in the feet. In the upper extremity, CSP latencies, duration, and suppression of electromyographic activity (EMG) did not differ. In the lower extremity, patients had reduced suppression of EMG during the CSP compared to normal controls. CSP durations exhibited a bimodal distribution in patients, including a subset of seven patients with durations shorter than all controls. This subset had profound loss of thermal sensation in the feet, but this was also true of some patients who had normal CSPs. Patients with shortened CSPs had modestly elevated vibration thresholds and reduced sensory potentials in comparison to patients with normal CSPs. Reduced CSPs in Fabry patients are associated with, but not entirely explained by, the severity of small-fiber neuropathy as measured by quantitative sensory testing. The possibility that large-diameter fibers provide a minor contribution to producing the CSP should be considered.

Abstract
Fabry disease is an X-linked glycosphingolipid storage disease caused by deficiency of alpha-galactosidase. Storage of globotriaosylceramide, also known as ceramide trihexoside, is maximal in blood vessels but also occurs in neurons. We performed neuropathological histochemical studies on the brains and spinal cords of 2 patients with confirmed Fabry disease. Luxol fast blue-positive deposits were found in blood vessels throughout the central and peripheral nervous system and within selected neurons in spinal cord and ganglia, brainstem, amygdala, hypothalamus, and entorhinal cortex. Regions adjacent to involved neuronal groups, including nucleus basalis, striatum, globus pallidus, and thalamus, were spared. Electron microscopy showed lamellar cytoplasmic neuronal inclusion bodies. Using a monoclonal antibody reactive with ceramide trihexoside, we found more extensive neuronal deposition than evident by Luxol-fast blue staining and new areas of neuronal storage in the spinal cord and cerebral cortex. Blood vessels throughout the nervous system were strongly immunoreactive. The highly selective pattern of neuronal involvement we found suggests that glycosphingolipid exposure, uptake, or catabolism varies greatly with respect to neuronal morphology and distribution. The degree of toxicity to neurons and the clinical significance of this neuronal storage remains to be defined.
