Sudden death from hypoglycemia, particularly hyperinsulinism, is often overlooked in forensic pathology. Histopathological differences in glycogen levels distinguish primary from secondary hypoglycemia, impacting diagnosis and understanding of sudden infant death.

Area of Science:

  • Forensic Pathology
  • Endocrinology
  • Neuropathology

Background:

  • Hypoglycemia, a state of abnormally low blood glucose, can lead to sudden death and is an under-recognized area in forensic pathology.
  • This study explores the pathogenesis of various hypoglycemia forms, differentiating primary (hyperinsulinism) from secondary (organ insufficiency) types.

Observation:

  • Three cases of sudden death due to hyperinsulinism-induced hypoglycemia are presented: two in infants with nesidioblastosis and one in an adolescent.
  • All hypoglycemia forms exhibit central nervous system damage, including neuronal degeneration, edema, microhemorrhage, and glial cell hyperplasia.

Findings:

  • Primary hypoglycemia shows preserved hepatic glycogen and increased muscle glycogen, unlike secondary hypoglycemia where glycogen is depleted.

  • Adrenal medulla hyperfunction is noted in primary hypoglycemia, but adrenal cortex activity is moderate, contrasting with the severe syndrome.
  • Differential diagnosis must consider rare anoxic events with hepatic glycogen resynthesis.

    • Implications:

    • Histopathological findings, especially hepatic glycogen levels, are crucial for distinguishing primary from secondary hypoglycemia in forensic cases.
    • Factors like hypoxia and hypothyroidism can promote primary hypoglycemic death, particularly in infants.
    • Secondary hypoglycemias are linked to exocrine pancreas normality and organic issues causing liver glycogen depletion.
