Adding a preventive short-course immunomodulatory regimen — rituximab, methotrexate, and intravenous immunoglobulins (IVIG) — to enzyme replacement therapy (ERT) safely provides long-term protection from antibodies that can block ERT’s effectiveness in children with classic infantile Pompe disease, a study found. These findings highlight that the benefits…

Children receiving enzyme replacement therapy (ERT) for Pompe disease often experience immune reactions to treatment, presenting as rashes or severe allergy, sometimes after several successful infusions, a case series shows. While these hypersensitivity reactions can be avoided successfully with anti-allergy medications and longer infusion times in some patients, others…
