Overview
Diazoxide-resistant hyperinsulinism refers to persistent hyperinsulinemic hypoglycemia that does not respond adequately to diazoxide therapy, necessitating alternative treatment strategies 1.Diagnosis
Elevated insulin levels with hypoglycemia despite diazoxide treatment 1.
Exclusion of other causes of hyperinsulinemic hypoglycemia through genetic testing and imaging studies 1.
Monitoring for complications such as pulmonary hypertension and necrotizing enterocolitis, especially in neonates 1.Management
First-line: Consider alternative pharmacological agents such as somatostatin analogs (e.g., octreotide) or GLP-1 receptor antagonists (e.g., exenatide) when diazoxide fails 1.
Adjunctive treatments: Surgical interventions like partial pancreatectomy may be required in severe cases 1.
Dosage caution: Avoid cumulative diazoxide doses exceeding 10 mg/kg/day to minimize risks of pulmonary hypertension and necrotizing enterocolitis 1.Special Populations
Neonates: Increased vigilance for pulmonary hypertension and necrotizing enterocolitis; echocardiography screening recommended 1.
Gender consideration: Higher incidence of necrotizing enterocolitis observed in males 1.Key Recommendations
Monitor neonates receiving diazoxide for signs of pulmonary hypertension and necrotizing enterocolitis, with echocardiography screening advised 1 (Evidence: Moderate).
Limit cumulative diazoxide dose to ≤10 mg/kg/day to reduce complication risk 1 (Evidence: Moderate).
Transition to alternative treatments like somatostatin analogs if diazoxide resistance is confirmed 1 (Evidence: Expert opinion).References
