I feel like I can live a normal life and I can do anything I want to do now,” says Watts. Glycogen storage disease (GSD) type I is a rare autosomal recessive disorder of glycogen metabolism that affects ≈1 in 100 000 live births (1). Conclusions: The experimental starch was superior to standard therapy in preventing hypoglycemia (. † 588 . Glycogen storage disease type I Glycogen storage disease (GSD) type I is also known as von Gierke disease or hepatorenal glycogenosis. “The patients who are finishing the first year got what we all thought was a test dose — one-third strength — yet the response has been dramatic. A potential treatment strategy for an often-fatal inherited glycogen storage disease has been identified by researchers. Because glucose-6-phosphatase catalyzes the final step of both glycogenolysis and gluconeogenesis, abnormal glucose-6-phosphatase activity results in impaired endogenous glucose production. Glycogen storage disease (GSD) is a rare condition that changes the way the body uses and stores glycogen, a form of sugar or glucose. vol. Of the 12 types of glycogen storage disease, type 1A is the most severe and causes low blood sugar, or hypoglycemia.

In seven patients with GSD-I with a mean age of 19.5 y (range: 18.8-21.7 y), we compared the biochemical effects of isoenergetic amounts of uncooked cornstarch (UCS; 1.76 +/- 0.41 g/kg) given in random order on consecutive nights either as a single dose at 2100 (time 0) or as equally divided doses … Administered through the patient's bloodstream, the new copy replaces deficient sugar enzymes caused by the disease and jump starts the body's glucose control. Photography is My Therapy. "The clinical trial is going better than expected. Before it can be stored, the body must combine the simple glucose units into a new, complex sugar called glycogen. University of Connecticut. Glucose comes from breaking down the food we eat. The clinical trial, conducted in conjunction with the biopharmaceutical company Ultragenyx, originally set out to simply test the safety and dosage of the gene therapy for three patients with GSD Type Ia. Von Gierke disease is a condition in which the body cannot break down glycogen. As the prognosis for this population has improved, the need to ensure appropriate cornstarch dosing for different age groups has become imperative. ScienceDaily. Uncooked cornstarch (UCCS) for the dietary management of hepatic Glycogen Storage Disease (GSD) has been the standard therapy in North America for the maintenance of normoglycemia in hepatic GSD. Its gene locus is at 12p12.2, and it is inherited as autosomal recessive. Glycosade to be taken as one dose. Weinstein, whose team first administered the investigational gene therapy at UConn John Dempsey Hospital in Farmington, Connecticut, on July 24, 2018, calls the results “remarkable.”. Eating many small meals that are low in sugar can help keep blood sugar levels normal while preventing excess glycogen storage … The dramatic improvement in their lives was unexpected.

Missed cornstarch doses no longer are resulting in hypoglycemia, which previously could have been life threatening.". GSD is an incurable disease in which her body is missing an enzyme to convert glycogen into glucose. The clinical trial, conducted in conjunction with the biopharmaceutical company Ultragenyx, originally set out to simply test the safety and dosage of the gene therapy for three patients with GSD Type Ia. If a cornstarch dose is missed, the disease can lead to seizures and even death. The condition was almost always fatal until 1971, when it was discovered that continuous glucose therapy could help these patients. All three will participate in the next phase — a 4-year follow-up clinical trial study. I'm a completely different person now that I was a year ago.
