Low levels of platelets in turn may lead to prolonged or excessive bleeding. It is the most common coagulation disorder among intensive care patients and is seen in a fifth of medical patients and a third of surgical patients. [3] A normal human platelet count ranges from 150,000 to 450,000 platelets/microliter (μL) of blood. [4]
Platelet transfusion alone is normally not recommended except in an emergency and is usually unsuccessful in producing a long-term platelet count increase. This is because the underlying autoimmune mechanism that is destroying the patient's platelets will also destroy donor platelets, and so platelet transfusions are not considered a long-term ...
Thrombotic thrombocytopenic purpura (TTP) initially presents with a range of symptoms that may include severe thrombocytopenia (platelet count usually < 30,000/mm³), microangiopathic hemolytic anemia (evidenced by schistocytes in the blood smear), and various clinical signs such as petechiae, purpura, neurologic symptoms, myocardial ischemia ...
Reactive thrombocythemia is the most common cause of a high platelet count. It accounts for 88% to 97% of thrombocythemia cases in adults, and near 100% in children. In adults, acute infection, tissue damage, chronic inflammation and malignancy are the common causes of reactive thrombocythemia. Usually, one or more of these conditions is ...
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 ]
Instead, the drugs affect new blood cells that are being made by the bone marrow. [4] When myelosuppression is severe, it is called myeloablation. [5] Many other drugs including common antibiotics may cause bone marrow suppression. Unlike chemotherapy the effects may not be due to direct destruction of stem cells but the results may be equally ...
Platelet transfusion, is the process of infusing platelet concentrate into the body via vein, to prevent or treat the bleeding in people with either a low platelet count or poor platelet function. [1] Often this occurs in people receiving cancer chemotherapy. [1]
Chemotherapy may be given with a curative intent (which almost always involves combinations of drugs), or it may aim only to prolong life or to reduce symptoms (palliative chemotherapy). Chemotherapy is one of the major categories of the medical discipline specifically devoted to pharmacotherapy for cancer, which is called medical oncology. [1] [2]
