  Pompe disease is an autosomal recessive disorder caused by a deficiency of acid alpha-glucosidase (GAA), resulting in failure of lysosomal glycogen degradation. Patients with late-onset Pompe disease experience progressive muscle weakness and decreased respiratory function. Enzyme replacement therapy (ERT) for lateonset Pompe disease became available for clinical use in 2006. Clinical studies have since demonstrated beneficial effects on motor and respiratory functions in treatment periods up to 4 years. We report an 8-year period wherein a patient with late-onset Pompe disease received ERT with recombinant human GAA. The patient initially showed marked improvement in motor functions. However, these improvements stopped approximately 5 years after ERT, followed by progressive declines in muscle strength. Our case demonstrates that resistance to ERT might d.. View More»
