Thrombotic thrombocytopenic purpura (TTP) is a blood disorder that results in blood clots forming in small blood vessels throughout the body. [2] This results in a low platelet count, low red blood cells due to their breakdown, and often kidney, heart, and brain dysfunction. [1]
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 ...
Glanzmann's thrombasthenia is an abnormality of the platelets. [2] It is an extremely rare coagulopathy (bleeding disorder due to a blood abnormality), in which the platelets contain defective or low levels of glycoprotein IIb/IIIa (GpIIb/IIIa), which is a receptor for fibrinogen.
The disorder can lead to very significant bleeding during even minor surgical procedures and women afflicted with the disorder often suffer significant bleeding during and after giving child birth, higher rates of miscarriages, and menorrhagia, i.e. abnormally heavy bleeding during the menstrual period.
The disorder was first described by Egeberg in 1965. [5] The causes of acquired antithrombin deficiency are easier to find than the hereditary deficiency. [3] The prevalence of antithrombin deficiency is estimated at ~0.02 to 0.2% of the general population, and 1-5% of patients with venous thromboembolism. [6]
The incorrectly glycosalated fibrinogen is dysfunctional and may cause pathological episodes of bleeding and/or blood clotting. [5] Congenital hypodysfibrinogenemia, an inherited disorder in which low levels of fibrinogen composed at least in part of a dysfunctional fibrinogen may cause pathological episodes of bleeding or blood clotting. [6]
This fibrinogen interferes with normal blood clotting and/or lysis of blood clots. The condition therefore may cause pathological bleeding and/or thrombosis . [ 2 ] [ 3 ] [ 4 ] Acquired dysfibrinogenemia is a non-hereditary disorder in which fibrinogen is dysfunctional due to the presence of liver disease , autoimmune disease , a plasma cell ...
The normal clotting process depends on the interplay of various proteins in the blood. Coagulopathy may be caused by reduced levels or absence of blood-clotting proteins, known as clotting factors or coagulation factors. Genetic disorders, such as hemophilia and Von Willebrand disease, can cause a reduction in clotting factors. [2]
