Abstract
BACKGROUND Gaucher disease (GD) is a rare autosomal recessive condition associated with clinical features such as splenomegaly, hepatomegaly, anemia, thrombocytopenia, and bone abnormalities. Three clinical forms of GD have been defined based on the absence (type 1, GD1) or presence (types 2 and 3) of neurological signs. Early diagnosis can reduce the likelihood of severe, often irreversible complications. The aim of this study was to validate the ability of factors from the Gaucher Earlier Diagnosis Consensus (GED-C) scoring system to discriminate between patients with GD1 and controls using real-world data from electronic patient medical records from Maccabi Healthcare Services, Israel's second-largest state-mandated healthcare provider. METHODS We applied the GED-C scoring system to 265 confirmed cases of GD and 3445 non-GD controls matched for year of birth, sex, and socioeconomic status identified from 1998 to 2022. The analyses were based on two databases: (1) all available data and (2) all data except free-text notes. Features from the GED-C scoring system applicable to GD1 were extracted for each individual. Patients and controls were compared for the proportion of the specific features and overall GED-C scores. Decision tree and random forest models were trained to identify the main features distinguishing GD from non-GD controls. RESULTS The GED-C scoring distinguished individuals with GD from controls using both databases. Decision tree models for the databases showed good accuracy (0.96 [95% CI 0.95-0.97] for Database 1; 0.95 [95% CI 0.94-0.96] for Database 2), high specificity (0.99 [95% CI 0.99-1]) for Database 1; 1.0 [95% CI 0.99-1] for Database 2), but relatively low sensitivity (0.53 [95% CI 0.46-0.59] for Database 1; 0.32 [95% CI 0.25-0.38]) for Database 2). The clinical features of splenomegaly, thrombocytopenia (< 50 × 109/L), and hyperferritinemia (300-1000 ng/mL) were found to be the three most accurate classifiers of GD in both databases. CONCLUSION In this analysis of real-world patient data, certain individual features of the GED-C score discriminate more successfully between patients with GD and controls than the overall score. An enhanced diagnostic model may lead to earlier, reliable diagnoses of Gaucher disease, aiming to minimize the severe complications associated with this disease.

Abstract
OBJECTIVES Gaucher disease type 1 (GD1) and Fabry disease (FD) are the two most common lysosomal storage diseases. For over three decades, effective enzyme replacement therapies (ERTs) have changed the fate of patients and offered a longer chance of survival and improve their quality of life. METHODS The clinical and molecular findings, endocrinological features and metabolic status of 26 patients (16 with FD, and 10 with GD1) were evaluated. The results were compared to age- and gender-matched healthy individuals. RESULTS Patients with GD1 and FD were followed for 7.2 ± 4.7 and 6.4 ± 4.3 years, respectively. Calcium and magnesium levels in patients with GD1 were lower than in controls (p=0.01; p=0.002). Osteoporosis was detected in 20% (n=2) of GD1 patients and 12.5% (n=2) of FD patients. The HbA1c value of GD1 patients was significantly lower than both in control and Fabry patients (p=0.004; and p=0.007, respectively). There was a negative correlation between LysoGb3 and female gender (p=0.04; r=-0.49), but no correlation was found with any other biochemical parameters. There was a negative correlation between the LysoGb1 level and the neutrophil (p=0.03; r=-0.711) and thrombocyte levels (p=0.02; r=-0.767), and a positive correlation with ferritin levels (p<0.001; r=0.867). CONCLUSION Long time effective ERT seems to have beneficial effects on metabolic and hormonal status as well as primary target organs in both FD and GD1 patients.

Abstract
Background Gaucher disease (GD) is one of the most prevalent lysosomal storage diseases and is associated with hormonal and metabolic abnormalities, including nutritional status disorders, hypermetabolic state with high resting energy expenditures, peripheral insulin resistance, hypoadiponectinaemia, leptin and ghrelin impairments, hypolipidaemia, linear growth deceleration and growth hormone deficiency, delayed puberty, hypocalcaemia and vitamin D deficiency. Specific treatments for GD such as enzyme replacement therapy and substrate reduction therapy display significant effects on the metabolic profile of GD patients. Main body of the abstract Hormonal and metabolic disturbances observed in both adult and paediatric patients with Gaucher disease type 1 (GD1) are discussed in this review. The PubMed database was used to identify articles on endocrine and metabolic disorders in GD1. GD1 appears to facilitate the development of disorders of nutrition, glucose metabolism and vitamin D insufficiency. Metabolic and hormonal diseases may have a significant impact on the course of the underlying disease and patient quality of life. Conclusions Conditions relating to hormones and metabolism can be wide-ranging in GD1. Obtained findings were intrinsic to GD either as a deleterious process or a compensatory response and some changes detected may represent co-morbidities. Actively seeking and diagnosing endocrine and metabolic disorders are strongly recommended in GD1 patients to optimize healthcare.

Abstract
Background Gaucher disease (GD) type I is the most common type of GD. Its main clinical manifestations are hepatosplenomegaly as well as bone and hematological abnormalities. The objective of the present study was to perform a literature review on the growth and metabolism of GD type I patients. Methods We searched Pubmed and Scielo.br databases with predetermined study limits: case series (n≥5), clinical trials, systematic reviews, and meta-analyses, and enzyme replacement therapy (ERT) with alglucerase or imiglucerase. The outcomes of interest were the following: growth and development, weight, height, malnutrition, overweight, obesity, basal metabolism, hypermetabolism, insulin resistance, and diabetes. A total of 175 articles were found, of which 28 met the inclusion criteria; these articles were grouped into three central themes: 1) growth of children and adolescents before and after ERT; 2) metabolic changes that remained during ERT; and 3) changes in metabolic status resulting from the treatment. Results and discussion The articles included in the present literature review are very heterogeneous, which hinders the analysis of data. They indicated that GD patients usually show low weight and height before ERT, which are improved with treatment in children and adolescents. Studies evaluating the energy metabolism by indirect calorimetry have indicated that the disease is associated with hypermetabolism. In adults, some changes in energy metabolism remain on ERT, and alterations, such as insulin resistance, seem to be associated with the treatment. It is not clear which are the required doses of imiglucerase for obtaining an adequate cost-effective relation, as well as the advisable therapeutic measures to avoid possible long-term adverse effects related to ERT. Conclusions ERT tends to normalise the growth of children and adolescents with GD type I, it seems to cause a partial response in relation to some metabolic changes associated with the disease, and it can causes metabolic changes such as weight gain in adult patients. Therefore, additional research is necessary.

Abstract
A 5-year-old girl was referred to the Department of Pediatrics and Neonatology, Guglielmo da Saliceto Hospital, Italy, because of growth retardation. Clinical and laboratory investigations showed pallor, hepatosplenomegaly, anemia and low/normal platelet count. Further investigations led to the diagnosis of Gaucher disease (GD). We believe this is the first report of growth hormone deficiency in a growth-retarded child with GD. After 1 year of imiglucerase replacement enzyme therapy, her bone age had normalized, linear growth rate had accelerated, and insulin growth factor-1 (IGF-1) and, perhaps more interestingly, growth hormone deficiency, had normalized. While the pathophysiological mechanisms underlying compromised growth in GD are poorly understood, the response to imiglucerase reported in this patient suggests that growth hormone deficiency is related to the underlying metabolic disorder in GD, rather than a primary endocrine pathology. Growth hormone deficiency adds to an already extensive list of possible clinical manifestations of this heterogeneous and complex disorder.

Abstract
Delivery of growth factors via the bloodstream for the treatment of various diseases is regulated in part by interactions with cell surface binding elements. Understanding the kinetics of growth factor binding and transport by cells would, therefore, be advantageous. This report quantifies the binding, internalization, and transport of insulin-like growth factor-I (IGF-I) across bovine aortic endothelial cells (BAEC) cultured in vitro. Binding analysis indicated that IGF binding proteins (IGFBPs), primarily localized with the extracellular matrix, were the primary IGF-I binding elements in our system, with twice as many binding sites (8.0 +/- 1.9 x 10(4) per cell) as IGF-I receptors (IGF-IR) (3.9 +/- 0.6 x 10(4) per cell). Internalization of IGF-I by IGF-IR, but not IGFBPs, was detected, however both receptor and IGFBP binding were shown to inhibit rather than enhance the transport of intact IGF-I, albeit in different ways. IGFBPs retained IGF-I in the apical region while IGF-IR binding led to protein degradation. Based on our computational modeling and experimental data, we hypothesize that IGFBPs could function as a reservoir for IGF-I, sequestering it for later release and transport, and that this reservoir function of the IGFBPs could be used to promote controlled localized delivery of IGF-I.

Abstract
UNLABELLED Gaucher disease is caused by defective activity of glucocerebrosidase. The resulting accumulation of glucocerebroside in the lysosomes of visceral macrophages in various tissue and organ compartments leads to multiple manifestations, including hepatosplenomegaly, anemia, thrombocytopenia, growth retardation and skeletal disease. The most prevalent form of Gaucher disease is the non-neuronopathic (type 1) variant, which lacks primary involvement of the central nervous system. Traditionally, this has been referred to as the 'adult type'; however, 66% of individuals with symptomatic non-neuronopathic Gaucher disease manifest in childhood. Onset in childhood is usually predictive of a severe, rapidly progressive phenotype and children with non-neuronopathic Gaucher disease are at high risk for morbid complications. Enzyme therapy with recombinant human glucocerebrosidase in childhood can restore health in reversible manifestations and prevent the development of irreversible symptoms. A heightened focus on pediatric Gaucher disease is therefore needed. Although some correlation has been found between genotype and phenotype, mutation analysis is of limited value in disease prognosis. Management of pediatric Gaucher disease should be underpinned by a thorough assessment of the phenotype at baseline with regular monitoring thereafter. Excluding neuronopathic disease is recommended as the first step. Subsequently, baseline evaluation should focus on staging of different storage tissues, particularly the bone the involvement of which results in the greatest long-term morbidity. These organ assessments are recommended because bone disease severity may not correlate with disease severity in other organs and vice versa. In addition, different organs may respond differently to therapy. Initial assessment of each organ system can enable setting of realistic and individualized goals. CONCLUSION A thorough approach to baseline assessment will improve the understanding of childhood Gaucher disease, optimizing management to minimize impairment of growth and development and prevent irreversible symptoms.

Abstract
UNLABELLED In individuals with non-neuronopathic Gaucher disease, childhood manifestations are usually predictive of a more severe phenotype. Although children with Gaucher disease are at risk of irreversible disease complications, early intervention with an optimal dose of enzyme therapy can prevent the development of complications and ensure adequate, potentially normal, development through childhood and adolescence. Very few, if any, children diagnosed by signs and symptoms should go untreated. Evidence suggests that disease severity, disease progression and treatment response in different organs where glucocerebroside accumulates are often non-uniform in affected individuals. Therefore, serial monitoring of the affected compartments is important. This should include a thorough physical examination at 6- to 12-monthly intervals. Neurological assessment should be performed to rule out neurological involvement and should be undertaken periodically thereafter in children who are considered to have risk factors for developing neuronopathic disease. Haematological and biochemical markers, such as haemoglobin, platelet counts and chitotriosidase levels, should be assessed every 3 months initially, but when clinical goals have been met through treatment with enzyme therapy, the frequency can be reduced to every 12 to 24 months. Careful monitoring of bone disease is vitally important, as the resulting sequelae are associated with the greatest level of morbidity. By combining various imaging modalities, the skeletal complications of non-neuronopathic Gaucher disease can be effectively monitored so that irreversible skeletal pathology is avoided and pain due to bone involvement is diminished or eliminated. Monitoring must include regular psychosocial, functional status and quality-of-life evaluation, as well as consistent assessment of therapeutic goal attainment and necessary dosage adjustments based on the patient's progress. CONCLUSION Through comprehensive and serial monitoring, ultimately, a therapeutic dose of enzyme therapy that achieves sustained benefits can be found for each child with non-neuronpathic Gaucher disease.
