An MRI-based study found that progression of white matter involvement in the brain among patients with infantile-onset Pompe disease (IOPD) occurred at different rates and correlated with cognitive decline — despite ongoing treatment. White matter abnormalities also were tied to elevated bloodstream levels of the neurofilament light chain (NfL)…

A newborn boy was diagnosed with both infantile-onset Pompe disease (IOPD) and sickle cell disease (SCD) in the first case study to report two co-existing genetic disorders. The boy was given enzyme replacement therapy (ERT), a standard Pompe treatment, and regular blood transfusions to prevent heart damage…

Stem cell-mediated gene therapy normalized glycogen build-up in muscle, heart, and brain tissue of a Pompe disease mouse model, a study shows. Treatments also restored cellular defects and motor impairment associated with the condition. The researchers recommended stem cell-based gene therapy as a candidate for future clinical development. The…

In an interview study, mothers of children who tested positive for Pompe disease in genetic newborn screening programs — and would be diagnosed with the late-onset type, or LOPD — expressed uncertainty about the age of symptom onset for their sons and daughters, and concerns about their child’s future.

Most children with Pompe disease in a small study developed antibodies against the enzyme replacement therapy Myozyme (alglucosidase alfa) — marketed in the U.S. as Lumizyme — but their presence did not limit treatment efficacy, its researchers reported. Children with the highest levels of antibodies also experienced most of…

Adults with late-onset Pompe disease in the U.K reported a long and distressing diagnostic process, with most patients calling in interviews for a reduced time to diagnosis, a shorter wait for a specialist appointment, and an earlier treatment start, a study found. At diagnosis — which often came only…

Based on a literature and database analysis, the predicted genetic prevalence of disease-related variants in the GAA gene — the underlying cause of Pompe disease — is higher in the Korean population than in Japanese, a study indicates. The study, “Two Approaches for a Genetic Analysis…

A large-scale analysis of the proteins and lipids found in the blood of people with Pompe disease showed significant changes involving inflammatory responses and the suppression of cellular processes such as immune function and lipid metabolism, a study reported. These findings…

Whole-body MRI found that a muscle in the shin is affected early on in children with either infantile or late-onset Pompe disease, a study shows. Such findings suggest earlier deterioration of this muscle, called tibialis anterior, in patients with more severe forms…

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…
