Gaucher disease: the role of the specialist on metabolic bone diseases

Area of Science:

• Rare disease research
• Skeletal dysplasias
• Lysosomal storage disorders

Background:

• Rare diseases affect <1 in 2000 individuals, often impacting pediatric populations.
• Over 400 rare diseases involve skeletal dysplasias, presenting complex challenges.
• Gaucher disease (GD), a lysosomal storage disorder due to beta-glucosidase deficiency, significantly impacts bone health.

Purpose of the Study:

• To highlight the skeletal manifestations of Gaucher disease.
• To emphasize the need for early and thorough evaluation of bone involvement in GD.
• To underscore the importance of multidisciplinary approaches for managing rare, debilitating diseases.

Main Methods:

• Review of skeletal manifestations in Gaucher disease.
• Discussion of diagnostic importance of biochemical markers and instrumental evaluations.
• Emphasis on quantitative and qualitative bone assessment.

Main Results:

• Gaucher disease causes diverse skeletal disorders, including Erlenmeyer flask deformity, lytic lesions, osteonecrosis, and pathological fractures.
• Bone disease is a primary source of morbidity in GD, severely impacting patient quality of life.
• Progressive damage affects both bone marrow and mineralized bone.

Conclusions:

• Early and comprehensive monitoring of bone health in Gaucher disease is crucial.
• Intervention based on biochemical and instrumental evaluations can prevent irreversible skeletal complications.
• Multidisciplinary care is essential for managing the complex, debilitating bone disease in GD.
