Enzyme replacement therapy

Enzyme replacement therapy
Other namesERT

Enzyme replacement therapy (ERT) is a medical treatment which replaces an enzyme that is deficient or absent in the body.[1] Usually, this is done by giving the patient an intravenous (IV) infusion of a solution containing the enzyme.[1]

ERT is available for some lysosomal storage diseases: Gaucher disease, Fabry disease, MPS I, MPS II (Hunter syndrome), MPS VI and Pompe disease.[1] ERT does not correct the underlying genetic defect, but it increases the concentration of the enzyme that the patient is lacking.[1] ERT has also been used to treat patients with severe combined immunodeficiency (SCID) resulting from an adenosine deaminase deficiency (ADA-SCID).[2]

Other treatment options for patients with enzyme or protein deficiencies include substrate reduction therapy, gene therapy, and bone-marrow derived stem cell transplantation.[1][3][4]
