Insights
Glycogen storage disease type I (GSD I) presents with hepatomegaly and hypoglycemia. Early diagnosis and management are crucial for improving patient outcomes and preventing severe complications.
Area of Science:
- Pediatric Endocrinology
- Metabolic Disorders
- Hepatology
Background:
- Glycogen storage disease type I (GSD I) is a rare inherited metabolic disorder.
- It is characterized by impaired glucose metabolism due to enzyme deficiencies.
- GSD I can lead to severe health complications if not managed promptly.
Purpose of the Study:
- To delineate the clinical characteristics of patients diagnosed with GSD I.
- To identify common presenting signs and symptoms.
- To evaluate long-term disease outcomes and management strategies.
Main Methods:
- Retrospective analysis of 6 pediatric patients with GSD I.
- Data collection included clinical presentation, laboratory findings, liver biopsy results, and treatment regimens.
- Patients were followed for 1 to 5 years.
Main Results:
- Common symptoms included hepatomegaly, hypoglycemia, abdominal pain, and growth failure.
- Key biochemical findings were hypoglycemia, lactic acidosis, and hypertriglyceridemia.
- Liver biopsies revealed glycogen-laden hepatocytes and increased fat content.
- Four patients had GSD Ia and two had GSD Ib, requiring diverse therapeutic approaches.
Conclusions:
- GSD I necessitates prompt recognition due to significant morbidity and potential mortality.
- Persistent hepatomegaly and hypoglycemia are critical indicators for considering GSD I.
- Long-term management involves metabolic interventions, anti-infective therapy, and potentially liver transplantation.
Background And Aims:
To describe the characteristics of patients with type I glycogenosis, the presentation types, the main clinical signs, the diagnostic criteria and also the disease outcomes on long term follow-up.
Methods:
The study group consisted of 6 patients (medium age 3 years 6 months) admitted in hospital between 2001 and 2005 and followed-up for 1 to 5 years. The sex ratio was 1:1.
Results:
The referral reasons varied from hepatomegaly incidentally discovered (3 of 6 patients) to abdominal pain (4 of 6 patients), growth failure (3 of 6 patients), symptoms of hypoglycemia (3 of 6 patients), recurrent epistaxis (1 patient). Hepatomegaly was present in all cases. Biological profile: hypoglycemia, increased transaminase values, hypertriglyceridemia, lactic acidosis, normal uric acid levels. Two patients had neutropenia and other two had increased glomerular filtration rate. Liver biopsy showed glycogen-laden hepatocytes and markedly increased fat. Four patients had type Ia and 2 patients type Ib glycogenosis. The therapy consisted of: diet, ursodeoxycholic acid, granulocyte colony-stimulating factor, broad spectrum antibiotics for those with type Ib glycogenosis. The follow-up parameters were clinical, biological, imaging. Metabolic interventions and antiinfectious therapy were necessary. All patients are alive, two of them on the waiting list for liver transplantation.
Conclusions:
Glycogen storage disease type I is a rare condition, but with possible life-threatening consequences. It has to be kept in mind whenever important hepatomegaly and/or hypoglycemia are present.
