Insights
Caregiver refusal of vitamin K prophylaxis in newborns can lead to severe, life-threatening bleeding disorders. Early intramuscular vitamin K administration is crucial for preventing and treating vitamin K deficiency bleeding in infants.
Area of Science:
- Pediatrics
- Hematology
- Public Health
Background:
- Vitamin K is essential for synthesizing active vitamin K-dependent procoagulant proteins.
- Vitamin K deficiency bleeding (VKDB) is a serious condition, especially late-onset VKDB in infants (1 week to 6 months).
- Exclusively breastfed infants are at higher risk due to low vitamin K levels in breast milk.
Observation:
- A 6-week-old exclusively breastfed infant male presented with severe hemorrhagic shock and multi-system organ failure.
- This critical condition was linked to caregiver refusal of routine intramuscular vitamin K at birth.
- Coagulation studies normalized within 8 hours of administering intramuscular vitamin K.
Findings:
- A rise in VKDB incidence is observed, correlating with increased caregiver refusal of intramuscular vitamin K.
- Health organizations worldwide stress the benefits of intramuscular vitamin K and the risks associated with its refusal.
- Infants, particularly those exclusively breastfed, face elevated risks of VKDB due to insufficient vitamin K intake.
Implications:
- This case underscores the potentially multi-system, life-threatening severity of preventable VKDB.
- It highlights the critical importance of universal vitamin K prophylaxis for all newborns.
- Healthcare providers must counsel caregivers on the risks of vitamin K refusal and the benefits of prophylaxis.
Abstract:
Vitamin K is an essential dietary cofactor required for the synthesis of active forms of vitamin K-dependent procoagulant proteins. Vitamin K deficiency, particularly late-onset deficiency occurring between 1 week and 6 months of age, can cause a life-threatening bleeding disorder. An exclusively breastfed, full-term, 6-week-old infant male presented with severe haemorrhagic shock and multi-system organ failure related to caregiver refusal of intramuscular vitamin K after birth. Coagulation studies were normalised within 8 hours of intramuscular vitamin K administration. An increasing number of caregivers are refusing intramuscular vitamin K which has led to a rise in the incidence of vitamin K deficiency bleeding. Health policy organisations around the world emphasise the benefits of intramuscular vitamin K and risks of refusal, particularly in exclusively breastfed infants who are at higher risk due to low vitamin K levels in breast milk. This case highlights the multi-system severity of this life-threatening yet preventable disorder.

Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...
