Treatment

  • Recommendation 1

    Enzyme replacement therapy with laronidase (Aldurazyme) can improve non-CNS symptoms

  • Recommendation 2

    is the standard treatment. Severe disease may require consideration of hematopoietic stem cell transplant.

Primary care

  • Recommendation 1

    Annual assessments to monitor for progressive skeletal, ophthalmic, cardiac, neurodevelopmental changes. Surgery may be needed to correct orthopedic abnormalities. Eye shades recommended to help with corneal clouding. Valve replacements may become necessary.

Further support

  • Recommendation 1

    Care typically requires an extensive multidisciplinary team

  • Recommendation 2

    large academic children's hospitals often have a Lysosomal Storage Disease program. Families can access support from the National MPS Society.Referral to Medical Genetics Department, if available. Initial virtual care is also available through organizations like TeleRare Health.
