Reduced activity of the COL13A1 gene, which codes for a protein involved in the communication between nerves and muscles, may contribute to the neuromuscular dysfunction and muscle weakness seen in people with Pompe disease, a new study suggests. This gene’s activity seems to be mediated by levels of glucose…

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…

A desensitization protocol allowed doctors to successfully treat an infant with classic infantile-onset Pompe disease (IOPD) who developed an allergic reaction to Myozyme (alglucosidase alfa), according to a report. The protocol, which was also used when the patient switched to Nexviadyme (avalglucosidase alfa), involved delivering the Pompe…

A woman in Canada with atypical and slowly progressive onset of muscle weakness affecting her eyelids, face, and throat muscles had shown symptoms for decades before being diagnosed with late-onset Pompe disease (LOPD), according to a study describing her case. Doctors considered several neuromuscular diseases before arriving at the…

Several cellular processes, particularly those related to lysosome function and autophagy, are altered in the muscles of people with late-onset Pompe disease (LOPD), and supplementation with an amino acid as a regulator could be a “promising therapeutic approach,” according to a study. Levels of L-arginine, an amino acid that…

Combining a symptom-based scoring tool with healthcare provider education may help identify patients who have an increased risk of having a missed diagnosis of late-onset Pompe disease (LOPD), a study in the U.S. shows. A LOPD diagnosis should be considered in patients with progressive muscle weakness and at least…

The U.S. Food and Drug Administration (FDA) has cleared Aro Biotherapeutics to conduct a Phase 1 clinical trial to test ABX1100, its experimental substrate reduction therapy, in people with late-onset Pompe disease (LOPD). The clearance of Aro’s investigational new drug (IND) application comes as the company is…

Young patients with late-onset Pompe disease (LOPD) who do not yet show disease symptoms should be regularly monitored for timely identification of symptoms so that treatment can be started early, a study suggested. Current diagnostic procedures enable early diagnosis of LOPD even in pre-symptomatic stages, said the researchers, who…

Last year, the team at Pompe Disease News brought our readers news on the most recent scientific advances, treatment progresses, and clinical trials for Pompe disease. Here are the 10 most read stories we published on Pompe disease during 2024. No. 10 – Switch from Lumizyme to Nexviazyme…

Three genes related to the regulation of immune responses — GPNMB, CALML6, and TRIM7 — show abnormal activity in immune cells infiltrating the muscles of people with infantile-onset Pompe disease, according to a new study from researchers in China. All three were found to be associated with regulatory T-cells, a…
