classic infantile-onset Pompe disease

Involvement in the brain and spinal cord’s white matter is common in Pompe disease, particularly in the infantile-onset form, according to a review of published studies. Other affected parts of the brain and spinal cord, or central nervous system (CNS), were the gray matter and blood vessels in the…

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…

Children with infantile-onset Pompe disease (IOPD) experienced reductions in disease-related biomarkers and stabilizations or improvements in clinical function after switching from Myozyme (alglucosidase alfa) — sold as Lumizyme in the U.S. — to Nexviazyme (avalglucosidase alfa), according to a new study from Taiwan. These functional improvements were…

Higher-than-approved doses of enzyme replacement therapy, or ERT, normalized several features of infantile-onset Pompe disease (IOPD), including motor and heart function, in the first patient enrolled in a pilot study. The patient began high-dose ERT as a newborn, and eventually met all developmental milestones by age 7. With…

Recently, I read an article here at Pompe Disease News that brought me back to six years ago, when my son Cayden was a newborn. The article, “Twins do well on high-dose ERT plus immune tolerance induction,” reminded me of when Cayden was going through a similar experience. Cayden…

Switching from Myozyme (alglucosidase alfa) to Nexviadyme (avalglucosidase alfa) led to gains in motor function and laboratory markers for four children with infantile-onset Pompe disease (IOPD) who took part in a compassionate use program in Italy. One child who’d had persistent heart disease on Myozyme also saw…

Two girls in Colombia with early-onset Pompe disease saw their symptoms improve after methotrexate treatment reduced the levels of antibodies they had developed against enzyme replacement therapy (ERT), according to a case report. ERT antibodies can cause the therapy to stop working. Methotrexate, a chemotherapy, can work as an…

Health-related quality of life for children with Pompe disease in the Netherlands is generally similar to healthy peers when self-reported, but worse when rated by their parents, a study found. Results also showed that children with classic infantile Pompe had greater fatigue and more limitations than those with non-classic…

For the first time ever, my 6-year-old son, Cayden, enjoyed a night of bowling. We discovered a program called Kids Bowl Free. Bowling allies that participate in this program offer kids ages 2-15 two free games every day during the summer. My mom and I took advantage of this amazing…

Researchers in the U.S. used a gene-editing tool in the lab to correct mutations known to cause infantile-onset Pompe disease, and this enabled patient-derived cells to produce a working version of the acid alpha-glucosidase (GAA) enzyme they lacked. The approach “may offer an efficacious, long-term therapy,” the researchers wrote,…
