Inherited or acquired protein C (PC) deficiency leads to thromboembolic events. Plasma PC activity in infancy is physiologically lower than in adults. We describe a case of neonatal asphyxia and acute renal failure associated with isolated PC deficiency. A full-term male infant was born to a healthy mother by caesarean section because of fetal distress. The small-for-gestational age infant showed 2 and 7 of Apgar scores at 1 and 5 minutes, respectively. Hypercoagulability required repeated infusions of fresh frozen plasma. Coagulation study revealed PC activity, 6%, protein S activity, 61%, and high D-dimer levels, along with normal factor VII activity and absent vitamin K deficiency. Anticoagulant and activated PC therapy improved coagulopathy and nephropathy. Imaging analyses indicated no visceral infarctions. Renal function and PC activity have been slowly normalized until 6 months of age. He had no PROC mutation or PC-deficient parents. Selective PC deficiency may occur as an acquired cause of hypercoagulable crisis in the stressed newborn.
