Disease progression

Treatment with Lumizyme (alglucosidase alfa) improved lung function in the short term and slowed lung function decline over the long term among people with late-onset Pompe disease (LOPD), according to a 13-year, real-world analysis. Patients with poor lung function before treatment saw the greatest early gains, while those…

Quantitative MRI (qMRI) imaging of the muscles is a useful technique for identifying signs of compromised muscle health in people with neuromuscular conditions like Pompe disease, according to a small study. The study identified specific patterns of qMRI changes in the thigh muscles of people with late-onset Pompe…

For most adults with late-onset Pompe disease (LOPD), a fairly significant improvement in walking ability is needed to be noticeable, but for patients who are already experiencing difficulty walking, a slowing of decline can be meaningful, a new study reports. “Patients with severe baseline conditions should not be expected…

Most people with classic infantile-onset Pompe disease (IOPD) develop brain abnormalities despite treatment with Myozyme (alglucosidase alfa), and these abnormalities are associated with poorer results on cognitive tests. That’s according to a study, “Long term survival in patients with classic infantile Pompe disease reveals a…

An easy survey of 20 questions agrees well with other tools used in clinical practice to measure physical function in people with late-onset Pompe disease (LOPD), according to a study that suggests it may aid in measuring and tracking symptoms over time. Having a reliable way to measure physical…

Despite being on enzyme replacement therapy (ERT) for a long time, some children with infantile-onset Pompe disease (IOPD) can still develop problems in the brain and spinal cord, a small study suggests. Manifestations such as overactive bodily reflexes, encephalopathy (damage to the brain), and…

Children with classic infantile-onset Pompe disease (IOPD), who were first treated as infants with Myozyme (alglucosidase alfa) — sold as Lumizyme in the U.S. — continue to experience heart, breathing, and cognitive deficits, as well as motor problems, despite long-term use of the older therapy, a small German…

Higher doses of Lumizyme (alglucosidase alfa) than what’s approved may improve survival outcomes for children with classic infantile onset Pompe disease (IOPD), according to a new study. An analysis of data from the Pompe Registry collected over nearly two decades showed that IOPD patients given Lumizyme at higher…

Mitochondria dysfunction is linked to hypertrophic cardiomyopathy — when the heart becomes enlarged and cannot pump blood efficiently — in people with Pompe disease, according to a new study from China. The disease-causing mechanisms were explored in a patient-derived heart cell model with characteristics of Pompe disease, including low…

Disease severity varied widely among adults with late-onset Pompe disease who underwent screening to assess their eligibility to participate in a gene therapy clinical trial, a study reports. Elevated levels of antibodies against the viral delivery vector were one of the exclusion criteria, suggesting that future studies may use…
