Insights
Late vitamin K deficiency bleeding is a serious condition in infants whose parents refuse vitamin K prophylaxis. This preventable disorder can cause severe harm, including brain damage and death.
Area of Science:
- Pediatrics
- Neonatology
- Public Health
Background:
- Late vitamin K deficiency bleeding (VKDB) is a rare but severe condition in exclusively breastfed infants.
- It is primarily observed in infants who do not receive vitamin K prophylaxis at birth, sometimes exacerbated by cholestasis.
Observation:
- Two male infants presented at 5 weeks old with subdural hematoma and midline shift.
- Both infants had not received recommended vitamin K prophylaxis in Germany.
- One infant also had cholestatic jaundice, an additional risk factor.
Findings:
- The cases highlight the recurrence of late VKDB due to parental refusal of vitamin K prophylaxis.
- Refusal of prophylaxis can lead to severe intracranial hemorrhage, with significant mortality and long-term neurological sequelae.
Implications:
- Healthcare providers must increase awareness among parents regarding the severe consequences of refusing vitamin K prophylaxis.
- Educating parents about the risks of late VKDB is crucial for prevention.
- Parental refusal of vitamin K prophylaxis may correlate with refusal of other routine childhood immunizations, posing risks to the community.
Introduction:
Late vitamin K deficiency bleeding in young infants is a rare disorder which occurs almost exclusively in breast-fed infants who did not receive proper vitamin K prophylaxis at birth and who might additionally suffer from cholestasis. Its impact on morbidity is high since in 50% of the cases it presents with intracranial hemorrhage with a mortality rate of 20% and life-long neurologic sequelae in 30% of the affected infants.
Case Reports:
2 male infants were both admitted to our unit at the age of 5 weeks with subdural hematoma with midline shift due to late vitamin K deficiency bleeding. Both infants did not receive the recommended Vitamin K prophylaxis in Germany. One patient presented with cholestatic jaundice on admission as an additional risk factor.
Discussion:
Parents who in the apparent best interest for their children refuse the recommended and well established vitamin K prophylaxis at birth leading to the reappearance of late vitamin K deficiency bleeding. These parents also tend to refuse routine immunizations of childhood in later life, which not only have an impact on their own child but might bear a risk for the whole community.
Conclusion:
It is the responsibility of health-care takers to show increased awareness to the growing number of parents refusing vitamin K prophylaxis at birth and educate them properly about the devastating consequences of late vitamin K deficiency bleeding.
