Treatment discovered for deadly childhood disease

08.12.2006
Researchers have discovered that a treatment involving enzyme replacement therapy dramatically reduces the risk of death in children with Pompe disease, a rare genetic disorder in which most children die before their first birthday.

The disorder causes profound muscle weakness and heart and breathing problems and affects as many as one in 40,000 births. The study is published in the online edition of Neurology, the scientific journal of the American Academy of Neurology.

"This form of treatment has changed the natural history of this otherwise lethal disease," said study author Priya Sunil Kishnani, MD, with Duke University in Durham, North Carolina.

The year long study involved 18 children under the age of six months with rapidly progressing Pompe disease. Pompe disease is caused by a deficiency in the enzyme acid a-glucosidase (GAA), which is needed to break down glycogen, a complex sugar molecule which releases glucose.

The study found all 18 children who started to receive the enzyme replacement, recombinant human GAA (rhGAA), before they were six months old survived to at least 18 months of age. Fifteen of the 18 children also did not need a ventilator. The study showed that starting rhGAA before the age of six months reduced the risk of death in children by 99 percent, reduced the risk of death or invasive breathing assistance by 92 percent, and reduced the risk of death or any type of ventilation by 88 percent, compared to past patients without this treatment.

"This form of enzyme replacement therapy markedly extended survival and improved respiratory performance in these children, with a majority of them showing normal growth and substantial gains in motor development," said Kishnani. "rhGAA is safe and the only effective treatment for Pompe disease; it is life saving."

Kishnani said the young age at which the children began treatment may have contributed to their improved response compared to previous trials with rhGAA, where patients were older.

"This study demonstrates that starting enzyme replacement therapy early, which could be facilitated by newborn screening, shows great promise to reduce the mortality and disability of babies with this devastating disorder," said Kishnani.

The most common side effects of the rhGAA treatment included skin reactions such as rash and hives, fever, and changes in heart rate. The study was supported by the Genzyme Corporation, maker of rhGAA.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
