Effectiveness of early initiation of idursulfase in infants and very young children with mucopolysaccharidosis II: a retrospective chart review in siblings

Infants treated earliest for Hunter syndrome showed better growth and fewer organ problems than older siblings who started treatment later.

INTRODUCTION: Enzyme replacement therapy (ERT) with intravenous idursulfase is the standard of care for patients with mucopolysaccharidosis II (MPS II; Hunter syndrome). GLMM analyses showed that, compared with their older siblings, patients who initiated ERT aged ≤12 months had better clinical outcomes for height-for-age Z-score, liver, cardiac, and musculoskeletal manifestations.
