Vitamin K deficiency induced hypoprothrombinemia

Vitamin K deficiency–induced hypoprothrombinemia is an acquired coagulopathy characterized by pathologically reduced levels of functional prothrombin (coagulation factor II) and other vitamin K–dependent clotting factors Affecting the hematologic system, it can develop in neonates due to limited transplacental transfer and low hepatic reserves, or across pediatric and adult populations secondary to severe malnutrition, fat malabsorption disorders, biliary obstruction, or broad-spectrum antibacte...

Vitamin K deficiency–induced hypoprothrombinemia is an acquired coagulopathy characterized by pathologically reduced levels of functional prothrombin (coagulation factor II) and other vitamin K–dependent clotting factors Pathophysiologically, insufficient vitamin K impairs the essential hepatic gamma-carboxylation required to synthesize biologically active clotting factors, leading to prolonged prothrombin time, elevated international normalized ratio (INR), and a heightened risk of mucocutaneou...
