Neonatal antithrombin III deficiency.
Abstract
Hemorrhagic and thrombotic complications are common in sick preterm infants and may reflect inadequate regulation of coagulation. All neonates have low levels of the pivotal regulator antithrombin III (ATIII) compared with adults. Plasma levels of ATIII are very low in preterm infants and are further diminished in infants with respiratory distress, necrotizing enterocolitis, sepsis, or disseminated intravascular coagulation. Babies with lower levels of ATIII in the cord blood have been shown to have a worse outcome than neonates with levels appropriate for gestational age, including higher mortality and increased incidence of intracranial hemorrhages and catheter-related thromboses. The origin of severe ATIII deficiency is unknown. Therapies with plasma replacement or anticoagulation have decreased the incidence and severity of hemorrhagic and thrombotic complications in high-risk infants in several clinical trials. These data lay the groundwork and rationale for potential use of ATIII replacement in deficient preterm infants.
