A man with late-onset Pompe disease (LOPD) was initially misdiagnosed with an inflammatory muscle disease called polymyositis, according to a case study highlighting the need to incorporate imaging tests in clinical practice to reduce the delay in diagnosis and treatment. After medication failed to improve his muscle strength, the…

Staying physically active according to the World Health Organization (WHO) guidelines and engaging in a personalized exercise program can significantly improve the physical well-being of adults with late-onset Pompe disease, a small study found. Moreover, regular physical activity was seen to delay disease progression among the study’s participants. “Endurance,…

Nearly 1 in 4 adults with late-onset Pompe disease develop high levels of antibodies against enzyme replacement therapy (ERT). However, that does not mean they have a reduced response to treatment, a systematic review study has revealed. The findings are in line with previous data from patients with…

While it is not very common, adults with late-onset Pompe disease (LOPD) may go undiagnosed or misdiagnosed, even if they show symptoms or signs suggestive of the disease, a study from Spain has found. Dried blood spots — a form of sampling where a drop of blood is blotted…

Adding the enzyme stabilizer miglustat did not improve the effectiveness of Lumizyme (alglucosidase alfa) or Nexviazyme (avalglucosidase alfa) in a mouse model of Pompe disease, a new study reports. “These data demonstrate that co-administration of miglustat with either [Lumizyme or Nexviazyme] to Pompe mice provides no additional…

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…

Three new mutations in the GAA gene were linked with heart disease and severe breathing problems in infants with infantile-onset Pompe disease (IOPD) in Malaysia, a study reports. “The novel mutations identified in this study expands the mutation spectrum for IOPD,” the researchers wrote. Also, among the 17 IOPD patients…

The strength of hip muscles and gait wherein only one leg is in contact with the ground were identified as key parameters that affect walking and falls in people with late-onset Pompe disease (LOPD). Both could help assess the effectiveness of new therapies and should be “priority targets for…

A new gene therapy for Pompe disease showed promise in a mouse model, researchers say, fully clearing in muscles the buildup of glycogen that characterizes the genetic disorder and also reducing it nearly completely in the brain. Glycogen is the stored form of glucose, or sugar — the body’s…

Heart defects detected with cardiac MRI (CMR) may help diagnose classic infantile-onset Pompe disease in early childhood, a case report from China suggests. An imaging exam showed a patient’s heart ventricles — the chambers that pump blood through the bloodstream and lungs — were enlarged, along with fibrosis (scarring).
