Persistent neonatal hyperinsulinemic hypoglycemia in two siblings successfully treated with diazoxide
Summary
Diazoxide effectively managed persistent neonatal hyperinsulinemic hypoglycemia in two siblings for extended periods. This treatment avoided the need for pancreatic surgery, offering a safe, long-term therapeutic option.
Area of Science:
- Pediatric Endocrinology
- Metabolic Disorders
- Neonatal Medicine
Background:
- Persistent neonatal hyperinsulinemic hypoglycemia (PNHH) is a rare but serious condition causing severe hypoglycemia in newborns.
- PNHH requires prompt and effective management to prevent long-term neurological complications.
- Surgical intervention, such as partial pancreatectomy, is often considered for refractory cases.
Observation:
- Two siblings presented with persistent neonatal hyperinsulinemic hypoglycemia.
- The condition required long-term management strategies.
- Treatment efficacy and safety were monitored over several years.
Findings:
- Diazoxide, at a dosage of 10 mg/kg/d, successfully controlled hypoglycemia in both siblings.
- One sibling was managed for eight years, and the other for one year, with diazoxide.
- No serious adverse side effects were reported during the treatment period.
Implications:
- Diazoxide represents a viable and safe medical management option for persistent neonatal hyperinsulinemic hypoglycemia.
- This approach can potentially obviate the need for invasive pancreatic surgery in select pediatric patients.
- Long-term diazoxide therapy may be a sustainable strategy for managing PNHH, improving patient outcomes.
