Glycogen-Storage Disease Type VI: Follow-up
Updated: Aug 4, 2008
Follow-up
Further Outpatient Care
- Perform follow-up evaluation to assess physical growth and to prevent hypoglycemic episodes by adjusting diet, as needed.
Deterrence/Prevention
- Instruct patients who exhibit episodes of fasting hypoglycemia to avoid prolonged fasts exceeding 5-7 hours.
- During an acute illness with decreased oral intake, maintain normoglycemia with intravenous infusion of glucose-containing solution.
Prognosis
- Patients have an excellent prognosis for normal stature and development, even without dietary management during childhood.
- Most patients exhibit resolution of hepatomegaly, hypotonia, muscle weakness, risk of fasting hypoglycemia, and abnormal biochemical parameters before or at puberty.
- The overall prognosis of rare variants with associated muscle or cardiac involvement depends on the severity of organ dysfunction.
Patient Education
- Educate patients and parents about proper diet management and fasting avoidance techniques.
- Parents and primary physicians of an affected child with episodes of fasting hypoglycemia should know how to administer intravenous glucose solutions during periods of acute illness with decreased oral intake.
Miscellaneous
Medicolegal Pitfalls
- Failure to educate the family about the effects of fasting and decreased oral intake during acute illness in those patients with episodes of fasting hypoglycemia
