A new noninvasive imaging tool called quantitative muscle ultrasound, or QMUS, can detect progressive muscle disease in people with infantile-onset Pompe disease (IOPD) who are on enzyme replacement therapy (ERT), according to a small study by U.S. researchers. The study found that QMUS correlated with functional status and…

A newborn whose symptoms initially mimicked oxygen deprivation was ultimately diagnosed with Pompe disease, highlighting potential challenges in identifying the condition, according to a case report from Italy. This was an uncommon presentation, according to researchers, who described the child’s symptoms, which included an enlarged heart and weak…

Wearable digital health technologies (DHTs) may help identify subtle walking and movement impairments in people with late-onset Pompe disease (LOPD) that are not evident in standard clinical evaluation, a recent study in Italy shows. These technologies “may have important implications for management, follow-up, and treatment decisions in clinical practice,”…

Locations where antibodies bind to enzyme replacement therapy (ERT) and potentially reduce its effectiveness in treating Pompe disease can now be identified using a drop of blood, a study reports. Knowing where anti-ERT antibodies bind may help find interventions to diminish the immune responses that generate them and also…

A man was diagnosed with late-onset Pompe disease (LOPD) after prenatal genetic counseling, even though he exhibited no symptoms. “This example stresses the importance of pretest consultation and the relevance of clinical and ethical implications during prenatal genetic testing for the whole family group,” scientists wrote. His condition was…

A 43-year-old woman who was experiencing breathing problems and muscle weakness was eventually diagnosed with late-onset Pompe disease (LOPD) through genetic testing, highlighting the challenges of diagnosing the condition due to its rarity and nonspecific symptoms, according to a study. “It is important to consider late-onset Pompe disease in…

Screening people with unexplained muscle weakness or elevated levels of muscle damage markers can help to identify people with late-onset Pompe disease (LOPD), a study found. The study, “Screening for Pompe disease in Serbian patients with limb-girdle muscle weakness,” was published in Clinical Neurology and Neurosurgery. LOPD…

A test that measures walking speed over 10 meters (33 feet) offers a simpler and less demanding alternative to the commonly used six-minute walk test for evaluating walking performance in Pompe disease, and may be a better option for patients who have difficulty covering longer distances. In a French…

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…

A woman in her 30s with severe respiratory failure and muscle weakness due to late-onset Pompe disease (LOPD) repeatedly experienced misdiagnoses of anxiety attacks — with “multiple admissions in the psychiatric sector with anxiety disorder” — before genetic testing eventually led to a correct diagnosis, according to a Danish…
