Successful treatment using agalsidase alfa of a patient with Fabry disease who had anaphylaxis after agalsidase beta: A case report.

Fabry disease is a rare genetic disease caused by a deficiency of α-galactosidase A gene (α-Gal A). Two intravenous enzymes administered every two weeks, agalsidase alfa and beta can slow disease progression and increase survival if administered early, before organ damage occurs. In this case report, we present a patient with a history of anaphylaxis to agalsidase beta who was successfully treated with agalsidase alfa.
