Gaucher disease (GD) is a rare, genetic lysosomal disorder leading to lipid accumulation and dysfunction in multiple organs. Involvement of the skeleton is one of the most prevalent aspects of GD and a major cause of pain, disability, and reduced quality of life. Uniform recommendations for contemporary evaluation and management are needed. To develop practical clinical recommendations, an international group of experienced physicians conducted a comprehensive review of 20 years' of the literature, defining terms according to pathophysiological understanding and pointing out best practice and unmet needs related to the skeletal features of this disorder. Abnormalities of bone modeling, reduced bone density, bone infarction, and plasma cell dyscrasias accompany the displacement of healthy adipocytes in adult marrow. Exposure to excess bioactive glycosphingolipids appears to affect hematopoiesis and the balance of osteoblast and osteoclast numbers and activity. Imbalance between bone formation and breakdown induces disordered trabecular and cortical bone modeling, cortical bone thinning, fragility fractures, and osteolytic lesions. Regular assessment of bone mineral density, marrow infiltration, the axial skeleton and searching for potential malignancy are recommended. MRI is valuable for monitoring skeletal involvement: It provides semiquantitative assessment of marrow infiltration and the degree of bone infarction. When MRI is not available, monitoring of painful acute bone crises and osteonecrosis by plain X-ray has limited value. In adult patients, we recommend DXA of the lumbar spine and left and right hips, with careful protocols designed to exclude focal disease; serial follow-up should be done using the same standardized instrument. Skeletal health may be improved by common measures, including adequate calcium and vitamin D and management of pain and orthopedic complications. Prompt initiation of specific therapy for GD is crucial to optimizing outcomes and preventing irreversible skeletal complications. Investing in safe, clinically useful, and better predictive methods for determining bone integrity and fracture risk remains a need. © 2019 The Authors.

戈谢病(GD)是一种罕见的遗传性溶酶体疾病,导致脂质在多个器官中积累和功能障碍。骨骼受累是 GD 最常见的特征之一,也是导致疼痛、残疾和生活质量下降的主要原因。需要对其进行当代评估和管理的统一建议。为了制定实用的临床建议,一组国际经验丰富的医生对 20 年来的文献进行了全面回顾,根据病理生理学的理解定义了术语,并指出了与这种疾病骨骼特征相关的最佳实践和未满足的需求。骨建模异常、骨密度降低、骨梗死和浆细胞异常与成年骨髓中健康脂肪细胞的移位相伴发生。过量生物活性糖脂的暴露似乎会影响造血以及成骨细胞和破骨细胞数量和活性的平衡。骨形成和分解之间的失衡会导致骨小梁和皮质骨建模紊乱、皮质骨变薄、脆性骨折和溶骨性病变。建议定期评估骨矿物质密度、骨髓浸润、脊柱和寻找潜在的恶性肿瘤。MRI 对监测骨骼受累具有重要价值:它提供骨髓浸润和骨梗死程度的半定量评估。当 MRI 不可用时,平片对监测疼痛性急性骨危机和骨坏死的价值有限。对于成年患者,我们建议对腰椎和左右髋部进行 DXA 检查,制定精心设计的方案以排除局灶性疾病;应使用相同的标准化仪器进行连续随访。通过常见措施可改善骨骼健康,包括摄入充足的钙和维生素 D 以及管理疼痛和矫形并发症。及时开始针对 GD 的特定治疗对于优化结果和预防不可逆转的骨骼并发症至关重要。投资于安全、临床有用和更好的预测方法来确定骨完整性和骨折风险仍然是一个需求。© 2019 作者。由 Wiley 期刊出版公司出版的《骨与矿物研究杂志》
