Long-term effects of enzyme replacement therapy in an elderly cohort of late-onset Pompe disease.

Enzyme replacement therapy (ERT) with recombinant human acid alpha-glucosidase (rhGAA) in late-onset Pompe disease (LOPD) shows beneficial effects in the first years often followed by a decline. We aimed to examine long-term ERT effects in an elderly LOPD cohort. Patients with age at diagnosis/start of ERT >50 years and ERT duration > seven years were included.

Urodynamic and clinical studies in patients with late-onset Pompe disease and lower urinary tract symptoms.

Aims: In late-onset Pompe disease (LOPD), a lysosomal storage disorder with glycogen accumulation in several tissues, patients suffer from progressive skeletal muscle weakness. Lower urinary tract symptoms (LUTS) have rarely been reported. The aim of this study is to objectively assess LUTS in patients with LOPD for the first time using urodynamic studies and to determine differences between LOPD patients with and without LUTS.
