Hypoprothrombinemia can be the result of a genetic defect, may be acquired as the result of another disease process, or may be an adverse effect of medication.For example, 5-10% of patients with systemic lupus erythematosus exhibit acquired hypoprothrombinemia due to the presence of autoantibodies which bind to prothrombin and remove it from the bloodstream (lupus anticoagulant ...
This seemingly paradoxical propensity to develop thrombosis in a disorder causing a decrease in a critical protein for blood clotting may be due to the function of fibrin (the split product of fibrinogen that is the basis for forming blood clots) to promote the lysis or disintegration of blood clots. Lower levels of fibrin may reduce the lysis ...
Hypodysfibrinogenemia, also termed congenital hypodysfibrinogenemia, is a rare hereditary fibrinogen disorder cause by mutations in one or more of the genes that encode a factor critical for blood clotting, fibrinogen. These mutations result in the production and circulation at reduced levels of fibrinogen at least some of which is ...
The haemostatic (blood clotting) system involves the interaction of proteins in the blood, the blood vessel wall and the flow of blood to control bleeding and blood clotting. Developmental Haemostasis is a term that represents the maturation of the haemostatic system from birth to adulthood. There are differences in the concentration, structure ...
Inhibition of coagulation and resultant internal bleeding can cause too few red blood cells to be present in the bloodstream and low blood pressure in newborns with fetal warfarin syndrome. [5] Low hemoglobin levels can lead to partial oxygen starvation, a high level of lactic acid in the bloodstream, and acidosis.
The dysfibrinogenemias consist of three types of fibrinogen disorders in which a critical blood clotting factor, fibrinogen, circulates at normal levels but is dysfunctional. Congenital dysfibrinogenemia is an inherited disorder in which one of the parental genes produces an abnormal fibrinogen.
Fresh frozen plasma (FFP) is a blood product made from the liquid portion of whole blood. [3] It is used to treat conditions in which there are low blood clotting factors (INR > 1.5) or low levels of other blood proteins. [3] [1] It may also be used as the replacement fluid in plasma exchange.
Antithrombin III deficiency (abbreviated ATIII deficiency) is a deficiency of antithrombin III.This deficiency may be inherited or acquired. [1] It is a rare hereditary disorder that generally comes to light when a patient suffers recurrent venous thrombosis and pulmonary embolism, and repetitive intrauterine fetal death (IUFD). [2]
