enzyme replacement therapy

A small molecule called 3-BrPA was able to lower levels of glycogen — a complex sugar that builds up to toxic levels in Pompe disease — and ameliorate muscle and heart structural defects in a new zebrafish model of the genetic disorder, a recent study has shown.

When used in combination with enzyme replacement therapy, albuterol improves lung and motor function in patients with late-onset Pompe disease (LOPD), a Phase 1/2 trial showed. Trial findings were reported in the study, “Improved muscle function in a phase I/II clinical trial of albuterol…

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…

Aging and vascular risk factors, not enzyme replacement therapy or the disease itself, may increase the risk of late-onset Pompe disease patients developing white matter lesions in the brain, a study suggests. The study, “White matter lesions in treated late onset Pompe disease are not different to matched controls,”…

Patients with late-onset Pompe disease (LOPD) should be followed regularly and start on enzyme replacement therapy (ERT) if they develop symptoms, according to an analysis of available guidelines. The study, “Comparison of recent pivotal recommendations for the diagnosis and treatment of late-onset Pompe disease using…

On a Friday the 13th some 20 years ago, 15-month-old Megan Crowley was diagnosed with Pompe disease. A few weeks later, so was her newborn brother, Patrick. Even the doctor who diagnosed the two children didn’t know much about the disease. Before that March day in 1998, he had…

A research team in Korea has developed a new method using rice to produce lab-made human acid alpha-glucosidase (GAA) for the treatment of Pompe disease. Their findings were published in the study, “N-glycan Remodeling Using Mannosidase Inhibitors to Increase High-mannose Glycans on Acid α-Glucosidase in Transgenic Rice…

Frequent inspiratory muscle training — a set of breathing exercises to strengthen the respiratory muscles making it easier to breathe — enhanced the breathing capacity of late-onset Pompe disease patients with insufficient respiratory function, a small pilot study has found. The study, “Safety and efficacy of short- and long-term…

Long-term interruption of enzyme replacement therapy (ERT) can lead to negative outcomes for late-onset Pompe disease patients, affecting their lung and exercise capacity as well as quality of life, a Swiss retrospective study shows. However, for most patients, resuming ERT can help restore the key clinical parameters that deteriorated during the pause…

Low-dose treatment with methotrexate can reduce the immune reaction that often accompanies enzyme replacement therapies in infants with Pompe disease, researchers report. Their study, “An immune tolerance approach using transient low-dose methotrexate in the ERT-naïve setting of patients treated with a therapeutic protein: experience in infantile-onset Pompe…
