Immune thrombocytopenic purpura (ITP), also known as idiopathic thrombocytopenic purpura or immune thrombocytopenia, is an autoimmune primary disorder of hemostasis characterized by a low platelet count in the absence of other causes.
Platelet transfusion refractoriness is the repeated failure to achieve the desired level of blood platelets in a patient following a platelet transfusion.The cause of refractoriness may be either immune or non-immune.
One common definition of thrombocytopenia requiring emergency treatment is a platelet count below 50,000/μL. [5] Thrombocytopenia can be contrasted with the conditions associated with an abnormally high level of platelets in the blood – thrombocythemia (when the cause is unknown), and thrombocytosis (when the cause is known).
Immune thrombocytopenic purpura is a condition in which platelets are destroyed by an autoimmune process. Platelets are a component of blood that contribute to the formation of blood clots in the body to prevent bleeding. The syndrome was first described in 1951 by R. S. Evans and colleagues. [1]
Thrombocytopenia – a deficiency of platelets; Pancytopenia – when all three types of blood cells; red blood cells, white blood cells, and platelets, are all deficient. This is a life-threatening disorder that is a characteristic of aplastic anemia. [3] There are also two general causes of cytopenia: autoimmune and refractory.
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 ]
Can we imagine ourselves back on that awful day in the summer of 2010, in the hot firefight that went on for nine hours? Men frenzied with exhaustion and reckless exuberance, eyes and throats burning from dust and smoke, in a battle that erupted after Taliban insurgents castrated a young boy in the village, knowing his family would summon nearby Marines for help and the Marines would come ...
Thrombocytopenia (low platelet count) – increased susceptibility to bleeding and ecchymosis (bruising), as well as subcutaneous hemorrhaging resulting in purpura or petechiae [8] [9] Many individuals are asymptomatic, and blood cytopenia or other problems are identified as a part of a routine blood count: [10] Neutropenia, anemia, and ...
