[Life-threatening hemorrhage caused by vitamin K deficiency in breast-fed infants]

Insights

Late-onset hemorrhagic disease of the newborn (HDN) can occur in breast-fed infants without vitamin K prophylaxis. This serious condition, sometimes fatal, underscores the need for universal vitamin K.

Area of Science:

  • Pediatrics
  • Neonatology
  • Hematology

Background:

  • Vitamin K deficiency can cause severe bleeding in infants.
  • Hemorrhagic disease of the newborn (HDN) is typically seen in the neonatal period.
  • Late-onset HDN beyond the neonatal period is less common but significant.

Observation:

  • Four infants (2 male, 2 female) presented with acute bleeding beyond the neonatal period.
  • All infants were born appropriate for gestational age and received no vitamin K prophylaxis.
  • All affected infants were exclusively breast-fed.

Findings:

  • Two infants experienced fatal intracranial hemorrhage.
  • The cases demonstrate the occurrence of late-onset hemorrhagic disease of the newborn.
  • Vitamin K deficiency was the underlying cause of the bleeding episodes.

Implications:

  • This study reinforces the existence and severity of late-onset HDN.
  • Universal vitamin K prophylaxis is crucial for preventing severe bleeding in infants.
  • Healthcare providers should consider vitamin K deficiency in breast-fed infants presenting with unexplained bleeding.
