The two main treatments for MPS I are enzyme replacement therapy (ERT) and bone marrow transplant. Both of these treatments work by replacing the missing IDUA enzyme. A drug called laronidase or Aldurazyme is the enzyme replacement therapy for MPS I. Treatment with laronidase can improve problems with breathing, growth, the bones, joints and heart. However, this treatment is not expected to treat problems with mental development because laronidase cannot cross the blood-brain barrier. A bone marrow transplant is another treatment option that provides the person with MPS I with cells that can produce the IDUA enyzme. A bone marrow transplant can stop the progression of neurological problems.
