enzyme replacement therapy

Infantile-onset Pompe disease (IOPD) patients who develop antibodies against enzyme replacement therapy (ERT) exhibit a distinct immune profile from those who don’t, according to recent research. Patients who developed these so-called high and sustained antibody titers, or HSAT, were skewed toward a type 2 immune profile, which the…

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…

It’s been a little more than 18 months since my 5-year-old son, Cayden, made the switch to Nexviazyme (avalglucosidase alfa) infusions as the main treatment for his infantile-onset Pompe disease. We started seeing improvements almost immediately, but now that he’s been on the new medication…

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…

The COVID-19 pandemic affected the treatment, as well as the physical and mental health, of people with Pompe disease, according to a recent survey of patients in 25 countries. More than 50% of respondents reported interruptions in enzyme replacement therapy (ERT) and physical therapy, affecting their disease, and…

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…

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…

For years, it’s been evident that my 5-year-old son, Cayden, has extremely sensitive skin. We first noticed the issue during one of his hospitalizations as a baby. We were at the children’s hospital for his enzyme replacement infusion, and when they removed the dressing from his port…

Some children with Pompe disease have dysfunctional motor neurons — the specialized nerve cells that control movement — in addition to muscle abnormalities, a new study highlights. Findings from the small study suggest that patients with motor neuron impairment may be less likely to see clinical benefits from…

Starting people with late-onset Pompe disease on enzyme replacement therapy (ERT) at any age can benefit their bone health, including reducing the risk of weak, brittle bones, or osteoporosis, a small study suggests. The study, “Effects of enzyme replacement therapy on bone density in late onset Pompe…
