Glycogen Storage Disease Type IV with Hepatomegaly and Elevated ALT/AST When Supportive Management Has Not Maintained Normoglycemia
This protocol addresses patients with Glycogen storage disease type IV (GSD IV) who present with hepatomegaly alongside elevated alanine aminotransferase (ALT) and elevated aspartate aminotransferase (AST) — findings that indicate hepatic involvement requiring further evaluation and management.
When supportive medical management of hepatic complications has not succeeded in maintaining normoglycemia, this protocol represents the indicated next step. The failure to sustain normoglycemia despite prior supportive measures is the clinical trigger for escalation.
In this setting, the next step involves a definitive surgical intervention targeting the liver. Specific indications and the full structured criteria are detailed in the complete evidence-based regimen — only a partial overview is shown here.

- For those with symptoms of hepatic involvement (i.e., hepatomegaly and elevated ALT and AST), a liver biopsy is recommended to assess the extent of liver disease.
- Liver transplantation is required for long-term survival in individuals with decompensated cirrhosis.
- Liver transplantation should be considered in individuals who exhibit evidence of significant liver dysfunction, signs of malnourishment or growth failure despite supplemental enteral feeding with maximal calories, or development of ascites due to portal hypertension, indicating decompensated cirrhosis.
