“…Known causes of DIC includes severe sepsis, acute haemolytic transfusion reaction, any form of shock, severe head injury or trauma, massive blood transfusion, vascular malformations, severe pancreatitis, obstetric complications such as intrauterine fetal demise, placental abruption, amniotic fluid embolism and others [39,40]. PNH is an acquired, progressive membrane defect that results from complement mediated lysis of red cells due to a defect in the PIG-A gene which anchors cyto-protective, complement regulating membrane surface proteins such as CD55 (decay accelerating factor, DAF), C8 binding protein (HRP) and most importantly, CD59 (membrane inhibitor of reactive lysis, MIRL) [41,42]. Most extracorpuscular defects are acquired, while most intracorpuscular defects are inherited except PNH.…”
