late-onset Pompe disease

Late-onset Pompe disease (LOPD) patients exhibit significant gene activity changes in their skeletal muscles compared with healthy people, some of which were normalized after six months of Nexviazyme (avalglucosidase alfa) treatment, a study found. Pathways involved in lysosome function, energy metabolism, and inflammation appeared to be most altered,…

I was excited yet nervous for my recent bucket-list vacation to Hawaii with my wife, Jean, her best friend from Montana, and one of my co-workers. The four of us flew six hours to Honolulu on Hawaiian Airlines and stayed on the ninth floor of Marriott’s Ko Olina Beach Club,…

In an interview study, mothers of children who tested positive for Pompe disease in genetic newborn screening programs — and would be diagnosed with the late-onset type, or LOPD — expressed uncertainty about the age of symptom onset for their sons and daughters, and concerns about their child’s future.

I remember the day vividly. It was an overcast morning on Saturday, Nov. 17, 2018. My wife and I hopped in the car and headed north toward Marina del Rey, California, giving me an hour to contemplate all the thoughts racing through my mind. A few months earlier, my neurologist…

A woman was diagnosed with advanced late-onset Pompe disease after three decades of being misdiagnosed, according to a recent case report. After diagnosis, the woman began treatment with Myozyme (alglucosidase alfa), which led to marked improvements that enabled her to live independently. The findings underscore a need for…

A report describes the unusual case of a man with late-onset Pompe disease (LOPD) that manifested with abnormalities in blood flow in the brain causing stroke-like symptoms. Abnormalities affecting blood vessels in the brain may be an under-recognized complication of LOPD, the researchers said. The study, “…

A small study in the U.K. is evaluating a noninvasive MRI-based tool that could potentially detect late-onset Pompe disease (LOPD) without the need for invasive muscle biopsies. This specialized muscle MRI also would monitor glycogen buildup — a hallmark of the condition — in muscles over time. The…

Age and the use of an assistive device like a walker may tell how well a patient with late-onset Pompe disease will do in a six-minute walk test (6MWT), a small study suggests. The 6MWT is considered a gold standard for determining, through difficulties in walking, the severity of…

The levels of BNIP3, a protein implicated in muscle fiber atrophy and increased autophagy — two features of late-onset Pompe disease (LOPD) — are increased in muscle samples from LOPD patients relative to healthy people, a small study shows. Autophagy is a pathway by which cells break down damaged…

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…
