Popis: Objective: Enzyme replacement therapy (ERT), the only approved therapy for infantile-onset Pompe disease (IOPD), had heterogeneous clinical effects due to factors such as severity, age at first treatment, dosage, and dosing regimens. We report the clinical and biochemical outcomes of a cohort of IOPD patients identified through newborn screening, and evaluating the dosage effect. Study design: A retrospective observational study was designed to describe the long-term clinical and biochemical outcomes of a uniform cohort of IOPD patients who have been treated with high-dosage of ERT. Results: Twenty-eight patients received alglucosidase alpha at either the labeled dosage followed by a high dosage (n = 23) or a high dosage exclusively (n = 5). At a median age of 8.3 years (0.8–17.3), 15 patients were walkers, 8 were weak walkers, and 5 were nonwalkers. The three groups exhibited a significant difference in the age of gross motor decline (p
