Lower urinary tract symptoms, including a loss of bladder control and unusual urine flow, are prevalent among children with classic infantile-onset Pompe disease (IOPD) who begin treatment early with enzyme-replacement therapy (ERT), according to a small study. Findings suggest that “pediatricians should actively seek to recognize children with IOPD…

Pain is relevant but appears to be unrelated to damage to small nerve fibers in the skin of late-onset Pompe disease patients who are using enzyme replacement therapy, a study found. The study, “Small fiber involvement is independent from clinical pain in late-onset Pompe disease,” was published in…

Adding L-alanine supplements to standard enzyme replacement therapy (ERT) for a young girl with Pompe disease led to improvements in several metabolic and body composition measures, a case report shows. According to researchers, this was the first known report of oral supplements of L-alanine — an amino acid,…

Recently, my 4-year-old son, Cayden, had an appointment with his metabolic specialist. This doctor manages everything related to his Pompe disease and is part of a team of doctors that diagnosed him when he was just 1 month old. They also oversee everything related to his enzyme replacement infusions.

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…

Interruptions to Myozyme enzyme replacement therapy (ERT) regimens during the COVID-19 pandemic led to worsened motor symptoms and poorer respiratory function in patients with Pompe disease, a French study found. These decreases in motor and respiratory function — seen after just a couple of months — were not…

Long-term treatment with Myozyme (alglucosidase alfa) — marketed in the U.S. as Lumizyme — results in variable but satisfactory motor and respiratory outcomes among older adults recently diagnosed with late-onset Pompe disease (LOPD), a study from Germany reported. According to its researchers, these findings were…

Patients with classic infantile-onset Pompe disease could benefit from increased dosing of Myozyme (alglucosidase alfa), an enzyme replacement therapy (ERT) marketed as Lumizyme in the U.S., according to a real-world European study. Benefits were seen in improved survival and ability to walk. “On the basis of our results,…

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…

L-carnitine — a molecule often taken as an oral dietary supplement — boosts the efficacy of enzyme replacement therapy (ERT), increasing by four times the activity of acid alpha-glucosidase (GAA), the faulty enzyme in Pompe disease, in patient-derived cells, a study shows. The molecule was found to stabilize…
