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 ]
Thrombotic thrombocytopenic purpura (TTP) is a life-threatening disorder characterized by thrombocytopenia and microangiopathic hemolytic anemia accompanied by variable neurological dysfunction, kidney failure, and fever. It is caused by severely reduced activity of the von Willebrand factor-cleaving protease ADAMTS13.
Thrombotic thrombocytopenic purpura (TTP), a TMA, was first described by the Hungarian born, American pathologist and physician Eli Moschcowitz (1879–1964). In 1924, [ 51 ] Moschcowitz first described TTP as a distinct clinicopathologic condition that can mimic the clinical characteristics of Hemolytic–uremic syndrome (HUS).
Liver disease, HELLP syndrome, thrombotic thrombocytopenic purpura, hemolytic uremic syndrome, and malignant hypertension may mimic DIC but originate via other pathways. [9] It is not the same as conditions where the blood vessels leak, such as capillary leak syndrome. [10]
Oral petechiae/purpura - immune thrombocytopenic purpura. Many cases of immune thrombocytopenic purpura (ITP), also known as idiopathic thrombocytopenic purpura, can be left untreated, and spontaneous remission (especially in children) is not uncommon. However, counts under 50,000/μL are usually monitored with regular blood tests, and those ...
Upshaw–Schulman syndrome (USS) is the recessively inherited form of thrombotic thrombocytopenic purpura (TTP), a rare and complex blood coagulation disease. USS is caused by the absence of the ADAMTS13 protease resulting in the persistence of ultra large von Willebrand factor multimers (ULvWF), causing episodes of acute thrombotic microangiopathy with disseminated multiple small vessel ...
Thrombotic microangiopathy (TMA) is a pathology that results in thrombosis in capillaries and arterioles, due to an endothelial injury. [1] It may be seen in association with thrombocytopenia, anemia, purpura and kidney failure. The classic TMAs are hemolytic uremic syndrome and thrombotic thrombocytopenic purpura.
These include obstetrical causes such as pre-eclampsia, HELLP syndrome (hemolysis, elevated liver enzymes and low platelets), or thrombotic microangiopathies that may occur during pregnancy. [63] Other causes of thrombocytopenia which may occur in pregnancy, such as drug induced thrombocytopenia , hereditary thrombocytopenia and ...
