          Abstract

          RESUMO A doença de Gaucher (DG) é a doença de depósito lisossômico mais prevalente, que se caracteriza pelo acúmulo de glicosilceramida e glucosilesfingosina em todos os tecidos do corpo. Com o advento da terapia de reposição de enzimas, o prognóstico dos pacientes com DG melhorou acentuadamente. Ainda assim, as manifestações esqueléticas associadas à DG respondem lentamente à terapia de reposição de enzimas e são as que contribuem de forma mais significativa para a morbidade do paciente. Esta revisão das manifestações ósseas da DG apresenta as mais recentes teorias sobre a sua fisiopatologia e uma revisão sistemática de estudos com pacientes latino-americanos que relataram a frequência das manifestações ósseas e os efeitos da terapia de reposição de enzimas sobre seu tratamento. Concluímos, destacando a importância da identificação precoce e do manejo adequado das doses apropriadas da terapia de reposição de enzimas para reduzir a morbidade causada pela DG.

Como conclusión, destacamos la importancia de la identificación temprana y del manejo adecuado de las dosis apropiadas de terapia de reemplazo enzimático para reducir la morbilidad causada por la EG.

          ABSTRACT Gaucher disease (GD) is the most prevalent lysosomal storage disease, and is characterized by the accumulation of glucosylceramide and glucosylsphingosine in tissues throughout the body. With the advent of enzyme replacement therapy, the prognosis for patients with GD has dramatically improved. Still, the skeletal manifestations associated with GD respond slowly to enzyme replacement therapy and are the most significant contributor of disease related patient morbidity. This review of bone manifestations in GD presents the most recent theories on its pathophysiology, and gives a systematic review of studies with Latin American patients that report the frequency of bone manifestations and the effects of enzyme replacement therapy on their treatment. We conclude by emphasizing the importance of early identification and proper management at appropriate dosage levels of enzyme replacement therapy to reduce the morbidity caused by GD.

          Phenotype, diagnosis, and treatment of Gaucher's disease.

          Gaucher's disease continues to be a model for applications of molecular medicine to clinical delineation, diagnosis, and treatment. Analyses of several thousand affected individuals have broadened the range of the pan-ethnic disease variants, provided initial genotype and phenotype correlations, and established the effectiveness of enzyme therapy. Large numbers of affected individuals worldwide have provided insight into the effect of disease variation related to ethnic origin, prognosis, and outcome. The ability to safely and effectively use enzyme therapy to inhibit or reverse visceral-disease progression and involvement has provided impetus for design of new enzyme therapies, and creation of substrate depletion and pharmacological chaperone strategies. Such innovations could provide interventions that are effective for neuronopathic variants and, potentially, could be more cost effective than other treatments. These developments are novel, clinically important, advancements for patients with other lysosomal storage diseases and genetic diseases.

            Executive summary of the 2013 International Society for Clinical Densitometry Position Development Conference on bone densitometry.

            The International Society for Clinical Densitometry (ISCD) convenes a Position Development Conference (PDC) every 2-3 yr to make recommendations for guidelines and standards in the field of musculoskeletal measurement and assessment. The recommendations pertain to clinically relevant issues regarding the acquisition, quality control, interpretation, and reporting of various aspects of musculoskeletal health metrics. Topics for consideration are developed by the ISCD Board of Directors and the Scientific Advisory Committee. For the 2013 PDC, body composition analysis was a central topic area for the first time and considered timely because of the scientific advances in measurement of fat and lean body mass by dual-energy X-ray absorptiometry (DXA). Indications for DXA and vertebral fracture assessment and use of reference data to calculate bone mineral density T-scores were also updated. Task Forces for each of these areas were assigned questions of relevance to a clinical audience and asked to conduct comprehensive literature reviews. Reports with proposed Position Statements were then presented to an international panel of experts. The Expert Panel included representatives of the International Osteoporosis Foundation, the American Society for Bone and Mineral Research, the National Osteoporosis Foundation, Osteoporosis Canada, and the North American Menopause Society. The PDC was held in Tampa, FL, contemporaneously with the Annual Meeting of the ISCD, March 21 through March 23, 2013. This report describes the methodology of the 2013 ISCD PDC and summarizes the results of the 2013 ISCD PDC for vertebral fracture assessment/DXA and National Health and Nutrition Survey (NHANES) Reference Database Task Forces. A separate article in this issue will summarize the results of the Body Composition Analysis Task Forces. Copyright © 2013. Published by Elsevier Inc.

              The Gaucher registry: demographics and disease characteristics of 1698 patients with Gaucher disease.

              The Gaucher Registry, the largest database of patients with Gaucher disease (GD) worldwide, was initiated to better delineate the progressive nature of the disorder and determine optimal therapy. This report describes the demographic and clinical characteristics of 1698 patients with GD before they received enzyme replacement therapy. Physicians worldwide who treat patients with GD were invited to submit prospective and retrospective data for an ongoing registry, using standardized data collection forms, for central processing and review. Most patients were from the United States (45%) and Israel (17%), but patients are from 38 countries. Most (94%) had type 1 GD, fewer than 1% had type 2, and 5% had type 3. Mutant allele frequency data, available for 45% of patients, showed the most common alleles to be N370S (53%), L444P (18%), 84GG (7%), and IVS2+1 (2%). Twenty-five percent of L444P homozygotes (13 of 52 patients) had type 1 GD phenotype. Mean age at diagnosis in patients with the N370S/N370S genotype was 27.2 years (SD, 19.7 years); in L444P/L444P patients, 2. 3 years (SD, 3.2 years). Histories of bone pain and radiological bone disease were reported by 63% and 94% of patients, respectively; both were more likely in asplenic patients than in patients with spleens. Mean spleen and liver volumes were 19.8 and 2.0 multiples of normal, respectively. Anemia and thrombocytopenia were present in 64% and 56%, respectively. Thrombocytopenia was present in 13% of asplenic patients. The Gaucher Registry permits a comprehensive understanding of the clinical spectrum of GD because of the uniquely large sample size. The Registry will be useful in evaluating the effects of specific therapies in GD and the possible influences of environment, ethnicity, and genotype on the natural history of the disorder.
