Severe Early-Onset Vitamin K Deficiency Bleeding in a Neonate Born to a Mother with Crohn's Disease in Clinical Remission: A Case Report.

Vitamin K deficiency bleeding (VKDB) in neonates is a significant disorder that causes skin, gastrointestinal, and intracranial hemorrhaging. Early-onset VKDB occurs within 24 hours of birth, and its prognosis is poor due to severe hemorrhage. The causes of early-onset VKDB include maternal intake of warfarin and anticoagulants, and maternal vitamin K deficiency.
