Vitamin K deficiency bleeding (VKDB) of the newborn, previously known as haemorrhagic disease of the newborn, [1] is a rare form of bleeding disorder that affects newborns and young infants due to low stores of vitamin K at birth. [2] It commonly presents with intracranial haemorrhage with the risk of brain damage or death. [3]
Vitamin K is a family of structurally similar, fat-soluble vitamers found in foods and marketed as dietary supplements. [1] The human body requires vitamin K for post-synthesis modification of certain proteins that are required for blood coagulation ("K" from Danish koagulation, for "coagulation") or for controlling binding of calcium in bones and other tissues. [2]
Newborn infants are a special case. Plasma vitamin K is low at birth, even if the mother is supplemented during pregnancy, because the vitamin is not transported across the placenta. Vitamin K deficiency bleeding (VKDB) due to physiologically low vitamin K plasma concentrations is a serious risk for premature and term newborn and young infants.

[6] It is used to treat certain bleeding disorders, [5] including warfarin overdose, vitamin K deficiency, and obstructive jaundice. [5]
Vitamin K is changed to its active form in the liver by the enzyme Vitamin K epoxide reductase. Activated vitamin K is then used to gamma carboxylate (and thus activate) certain enzymes involved in coagulation: Factors II, VII, IX, X, and protein C and protein S. Inability to activate the clotting cascade via these factors leads to the bleeding ...
