Early vitamin K deficiency bleeding in a neonate associated with maternal Crohn's disease

We report herein a case of early vitamin K deficiency bleeding (VKDB) in a neonate associated with maternal Crohn's disease. A female neonate was born at 37 weeks' gestation and weighed 2778g. She developed broad purpura on her back on day 1. Laboratory data showed anemia, prolonged coagulation time and elevated protein induced by vitamin K absence or antagonist-11. Early VKDB has not been reported in a neonate born from mother with active Crohn's disease. It is essential to give vitamin K selectively as soon as possible after birth to prevent early VKDB in neonates.
