Conclusions: The experimental starch was superior to standard therapy in preventing hypoglycemia (. von Gierke described the first patient with GSD type I in 1929 under the name hepatonephromegalia glycogenica. ScienceDaily. Glycogen Storage Disease (GSD) Glucose (a type of sugar) is a key source of energy (fuel) for the body. Glycogen storage disease type 0 is secondary to a lack of glycogen synthethase activity, which causes a marked decrease in liver glycogencontent. First, the cornstarch dose at the start of each controlled fasting challenge was reduced from 35 grams to 5 grams to reduce an acute rise in glucose … Weinstein, the clinical trial’s lead investigator, is pediatric endocrinologist-scientist who cares for more than 700 GSD patients from 51 countries as director of the Glycogen Storage Disease Program at Connecticut Children’s and UConn Health — the largest center in the world for the care and treatment of this condition. The gene therapy works by delivering a new copy of a gene to the liver via a naturally occurring virus. Have any problems using the site? The results are way beyond my imagination," says Weinstein. I'm a completely different person now that I was a year ago. In addition to totally stopping daily cornstarch consumption, Watts has experienced normal regulation of his blood glucose levels, weight loss, increased muscle strength, and marked improvement in his energy. One year after patient Jerrod Watts first received the GSD vaccine during a 30-minute infusion, he is completely off of cornstarch. Aim: To determine the individual fasting tolerance for patients with glycogen storage disease type III (GSD III) and to assess their linear growth velocity after tailoring of dose intervals of oral uncooked cornstarch. 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. Being older I did go low on dose so it is 10-20 g 4x a day. However, it has limited duration of action and therefore must be given every 4–6 hours, day and night. The gene therapy works by delivering a new copy of a gene to the liver via a naturally occurring virus. One of the biggest reliefs from this gene therapy is I can now sleep through the night without worrying about dying in the middle of the night. GSD I (OMIM 232200) is caused by reduced activity of glucose-6-phosphatase (G6Pase, EC 3.1.3.9); GSD Ia by deficiency of the hydrolytic enzyme; and GSD Ib by deficiency of the endoplasmic reticulum transmembrane glucose 6-phosphate transport protein, G6P translocase.
