Prothrombin deficiency is a bleeding disorder that slows the blood clotting process. People with this condition often experience prolonged bleeding following an injury, surgery, or having a tooth pulled. In severe cases of prothrombin deficiency, heavy bleeding occurs after minor trauma or even in the absence of injury (spontaneous bleeding). Women with prothrombin deficiency can have prolonged and sometimes abnormally heavy menstrual bleeding. Serious complications can result from bleeding into the joints, muscles, brain, or other internal organs. Milder forms of prothrombin deficiency do not involve spontaneous bleeding, and the condition may only become apparent following surgery or a serious injury.
Mutations in the F2 gene cause prothrombin deficiency. The F2 gene provides instructions for making the prothrombin protein (also called coagulation factor II), which plays a critical role in the formation of blood clots in response to injury. Prothrombin is the precursor to thrombin, a protein that initiates a series of chemical reactions to form a blood clot. After an injury, clots protect the body by sealing off damaged blood vessels and preventing further blood loss.
Prothrombin deficiency is very rare; it is estimated to affect 1 in 2 million people in the general population.
This condition is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.

Summary: This is a non-interventional, multicenter, observational, international study in male persons with haemophilia A who have developed inhibitors to any replacement coagulation factor VIII (FVIII) product. The purpose of the study is to capture different approaches in the management of persons with haemophilia A and FVIII inhibitors, document current immune tolerance induction approaches, and evaluat...
Summary: No randomized controlled trial (RCT) has investigated the effect of prophylactic fresh frozen plasma (FFP) transfusion in septic or critically ill patients with coagulation abnormalities. The last Surviving Sepsis Campaign therefore suggests with a very low quality of evidence against the use of fresh frozen plasma during septic shock to correct clotting abnormalities in the absence of bleeding or...
