Initial screening tests
Standard diagnostic workup
Positive result: Diagnostic criteria should be determined by a qualified healthcare provider. [Content pending medical review.]
Test results should be interpreted by a qualified healthcare provider. [Content pending medical review.]
Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Enzyme replacement therapy
Intravenous administration of recombinant enzymes to replace deficient lysosomal enzymes. This disease-modifying treatment addresses the underlying biochemical defect and reduces substrate accumulation in cells.
Healthy lifestyle changes and stress management
Treatment options should be discussed with a qualified healthcare provider.
Substrate reduction therapy
Oral pharmacological approach to reduce the production of substrates that accumulate in lysosomal storage diseases. May be used alone or in combination with enzyme replacement therapy.
Additional treatment options
Hematopoietic stem cell transplantation
Bone marrow or stem cell transplant to provide a source of functional lysosomal enzymes from donor cells. Reserved for severe cases or when other therapies are insufficient.
surgicalMultisystem surveillance program
Comprehensive monitoring of affected organ systems including neurological, cardiac, pulmonary, and skeletal assessments. Regular imaging and functional testing guides treatment adjustments.
monitoringMultidisciplinary supportive care
Coordinated supportive approach addressing mobility, nutrition, respiratory function, and quality of life. Includes physical therapy, occupational therapy, and nutritional support tailored to individual needs.
