Lung Function Reduced in LOPD Despite Long-term Myozyme Use

Despite treatment for years with Myozyme (alglucosidase alfa) — marketed in the U.S. as Lumizyme — people with late-onset Pompe disease (LOPD) still develop airway abnormalities and experience reduced lung function, a small Taiwanese retrospective study shows. While none of the five patients in the study required a ventilator…

Nexviazyme Approved in Canada as Next-gen ERT for Late-onset Pompe

Nexviazyme (avalglucosidase alfa), a next-generation enzyme replacement therapy, has been approved by Health Canada for people with late-onset Pompe disease ages 6 months and older. “The Health Canada approval of Nexviazyme is an important milestone for Canadian Pompe patients and may represent a new standard of care,” Mark…

LOPD Adults in China Cite Poor Quality of Life

Adults with late-onset Pompe disease (LOPD) report worse physical health and quality of life than their counterparts with other rare diseases, a national survey in China has found. In the study, however, stronger social support — in the form of social interaction — was linked to better quality of…

New GAA Mutations ID’d as Cause of Late-onset Disease

Four new mutations in the GAA gene have been identified in a group of people with late-onset Pompe disease (LOPD), according to a study in Spain. The study “Genotype–phenotype correlation of 17 cases of Pompe disease in Spanish patients and identification of 4 novel GAA variants” was published in the Orphanet…

Different Types of Mutations Appear to Predict Pompe Subtypes

The type of genetic mutation carried by a Pompe disease patient appears to predict whether the disease is infantile- or late-onset, according to a study. However, newly diagnosed patients should still undergo complete genetic, cardiac, and neurological tests, scientists stated. The study, “Phenotypic implications of pathogenic…
