Dairy-free milkshakes Glycogen storage disease type also affect blood cells, the heart, kidneys, and other organs. Normally, glycogen is stored in the liver until the body needs energy. Then, enzymes convert glycogen into glucose so that it can travel through the bloodstream to cells that need fuel. Every cell in the body contains enzymes, but children with GSD lack one of the enzymes responsible for making glycogen or converting glycogen to glucose.Glycogen storage disease type -
A combination of uncooked cornstarch mixed in water, soy formula, or soy milk is often recommended. Cornstarch is digested slowly, so it provides a steady release of glucose in between feedings.
Current treatments consist of providing small, frequent feedings during the day. Most doctors agree that certain sugars should be restricted, but the degree of restriction is still debated.
In some cases, an overnight tube feeding, typically via a naso-gastric tube, is required to provide a continuous delivery of glucose. GSD I is an inherited genetic disorder. The effects of the disease are apparent very early in childhood. Clinical trials are research studies that test how well new medical approaches work in people.
Before an experimental treatment can be tested on human subjects in a clinical trial, it must have shown benefit in laboratory testing or animal research studies. The most promising treatments are then moved into clinical trials, with the goal of identifying new ways to safely and effectively prevent, screen for, diagnose, or treat a disease.
Speak with your doctor about the ongoing progress and results of these trials to get the most up-to-date information on new treatments. Participating in a clinical trial is a great way to contribute to curing, preventing and treating liver disease and its complications.

All Glycogen Storage diseases together affect fewer than 1 in 40, persons in the United States. Information for the Newly Diagnosed What are the symptoms of GSD I? What causes GSD I?
How is GSD I diagnosed? How is GSD I treated? Who is at risk for GSD I? Therefore, a liver function test should be repeated every 6 to 12 months. Liver transplantation is an option for patients with multifocal growing lesions that do not respond to primary treatment. As per guidelines for the management of GSD I published by the collaborative European study [8] , the following biomedical targets are recommended:.
It is important to differentiate GSD I from other diseases that present with hepatomegaly and or hypoglycemia. Dietary therapy is the first line treatment for patients with GSD I.
However, to prevent long-term complications of the disease such as hepatocellular adenoma HCA , hepatocellular carcinoma HCC , renal failure among others, gene therapy in animal models of GSD is showing potential for the future trial in humans. The most likely etiology for HCC is the transformation of adenomas to carcinoma.
In such patients, the diagnosis of HCC is challenging due to the abundance of adenomas making biopsy difficult along with normal levels of biomarkers like a-fetoprotein and carcinoembryonic antigen.
If a hepatic adenoma is detected, liver ultrasound or MRI examinations is repeated every 3 to 6 months. Due to an increased risk of developing HCA, female patients with GSD I should avoid combined oral contraception. Patients with GSD I may develop bleeding disorders from impaired platelet function.
There is also an increased risk of osteoporosis and fractures from vitamin D deficiency. Therefore, routine monitoring of vitamin D levels along with dual-energy x-ray absorptiometry DXA scans is recommended to monitor the bone density and the need for vitamin D supplementation.
Renal failure may occur due to proximal renal tubular or renal glomerular dysfunction. Thus patients then develop anemia of chronic kidney disease that may be further exacerbated by iron deficiency, chronic metabolic acidosis or bleeding diathesis.
Anemic patients are treated with EPO therapy after screening them for iron deficiency and replenishing their iron stores.
Patients with uncontrolled blood lactate, serum lipids, and uric acid levels are also at an increased risk for nephropathy that may need renal transplantation.
Therefore, an annual ultrasound examination of the kidneys is recommended after the first decade of life. Other complications include menorrhagia and polycystic ovaries in females, and gout from hyperuricemia. Dietary therapy maintains the patient's blood glucose levels and reduces the early symptoms.
However, to avoid long-term complications such as HCA, HCC, and renal failure, gene therapies in GSD I mice models showed promise. Types of glycogen storage diseases Contributed by William L. Disclosure: Nirzar Parikh declares no relevant financial relationships with ineligible companies.

Continuing Education Activity Glycogen storage disease type I GSD I , also known as Von Gierke disease, is an inherited disorder caused by deficiencies of specific enzymes in the glycogen metabolism pathway. Introduction Glycogen storage disease type I GSD I , also known as Von Gierke disease, is an inherited disorder caused by deficiencies of specific enzymes in the glycogen metabolism pathway.
Etiology GSD Ia results from mutations in the G6PC gene on chromosome 17q21 that encodes for the G6Pase-a catalytic subunit. Pathophysiology The enzyme G6Pase is primarily expressed in the liver, kidney, and intestine.
Histopathology The availability of gene sequencing makes liver biopsy unnecessary. History and Physical Some patients with GSD I may present with hypoglycemia and lactic acidosis in the neonatal period.
Evaluation Initial laboratory findings in patients with GSD I will show hypoglycemia, lactic acidosis, hyperuricemia, hypercholesterolemia, and hypertriglyceridemia. Differential Diagnosis It is important to differentiate GSD I from other diseases that present with hepatomegaly and or hypoglycemia.
Pertinent Studies and Ongoing Trials Dietary therapy is the first line treatment for patients with GSD I. Medical Oncology The most likely etiology for HCC is the transformation of adenomas to carcinoma. Complications Patients with GSD I may develop bleeding disorders from impaired platelet function.
Enhancing Healthcare Team Outcomes Dietary therapy maintains the patient's blood glucose levels and reduces the early symptoms. Review Questions Access free multiple choice questions on this topic.
