muscle strength

Gene and enzyme replacement therapies for Pompe disease improved breathing and limb strength in a mouse model of the disease, a study showed. The researchers said the improvement was associated with glycogen clearance in the tongue, the lungs, and the diaphragm, the main muscle involved in respiratory control. Glycogen…

People with Pompe benefit from the same types of exercise as the general population; however, they should avoid very intense exercise due to the potential of muscle damage. Physical therapist Tracey Boggs gives us the scoop on exercise for the Pompe patient.

The six-minute walk distance (6MWD) test is a reliable measure of declines in motor abilities in people with late-onset Pompe disease (LOPD), a two-year study that evaluated a series of such tests reported. Other common measures of motor function and muscle strength failed to reliably detect such changes in…

Gene therapy given with chaperones — specific molecules known to stabilize the structure of proteins — was found to enhance the availability of acid alpha-glucosidase, known as GAA, the missing or defective enzyme in Pompe disease (PD), in a mouse model. The treatment subsequently eased disease symptoms, with the…

In the first years of treatment, Myozyme (alglucosidase alfa) — marketed in the U.S. as Lumizyme — can effectively increase physical endurance, and improve lung function and muscle strength in adults with late-onset Pompe disease (LOPD), a real-world study found. Yet, despite this treatment, patients’ clinical outcomes, particularly lung…

People with late-onset Pompe disease (LOPD) show significant increases in the amount of muscle replaced by fat while on treatment, which is linked to reduced muscle strength and motor function, according to a new study.  These findings support the use of muscle imaging to assess…

Muscle strength and function measurements in people with late-onset Pompe disease (LOPD) correlate with whole-body magnetic resonance imaging (WBMRI) results, a new study suggests. The study, “Whole‐body MRI in Late‐onset Pompe Disease: Clinical utility and correlation with functional measures,” was published in the Journal of Inherited Metabolic…

Long-term enzyme replacement therapy (ERT) to treat people with Pompe disease loses effectiveness in maintaining walking ability, muscle strength, and lung function, a new study shows. Despite these results, ERT improved lung function when compared to the predicted outcome without ERT, and some patients responded…

Amicus Therapeutics’s investigational therapy AT-GAA (ATB200/AT221) continues to show promise as a safe and effective treatment for adults with Pompe disease, according to the latest results from an ongoing Phase 1/2 clinical trial. Pompe disease is caused by acid alpha-glucosidase (GAA) enzyme deficiency, leading to the build-up of glycogen…
