What is SCPCD?

Severe Congenital Protein C Deficiency is a rare autosomal recessive disorder that leads to high initial mortality and long-term morbidity in survivors.1,2
In neonates, SCPCD can manifest, as early as 2-12 hours after birth, as purpura fulminans with necrosis of the skin, disseminated intravascular coagulation, arterial and venous thrombosis.2-4


Sometimes, purpura fulminans can hide SCPCD.

A frequent cause of purpura fulminans in neonates is severe infections and associated sepsis. However, Severe Congenital Protein C Deficiency (SCPCD) can also lead to purpura fulminans, with lesions appearing as early as 2-12 hours after birth.1,3 A timely protein C test can help physicians diagnose and manage this rare condition, allowing rapid management that may reduce morbidity and save the lives of infants.2,3
