Other causes of reactive thrombocythemia include: post surgery, iron deficiency, drugs, and rebound effect after bone marrow suppression. [8] Research suggests that thrombocytosis can also occur after physical exercise, and is triggered by hemoconcentration and the release of platelets from the liver, lungs and spleen. [3] [9]
Procoagulant platelets are a functional subgroup of platelets with distinct properties in physiological haemostasis. Following strong activation, procoagulant platelets express phosphatidylserine on their surface and become highly efficient in sustaining thrombin generation and parallelly gain pro-haemostatic function by retaining α-granule proteins on their membranes. [1]
Antiplatelet therapy with one or more of these drugs decreases the ability of blood clots to form by interfering with the platelet activation process in primary hemostasis. Antiplatelet drugs can reversibly or irreversibly inhibit the process involved in platelet activation resulting in decreased tendency of platelets to adhere to one another ...
Bleeding time is a medical test done to assess the function of a person's platelets. It involves making a patient bleed, then timing how long it takes for them to stop bleeding using a stopwatch or other suitable devices. The term template bleeding time is used when the test is performed to standardized parameters.
The International Osteoporosis Foundation and the European Calcified Tissue Society recommend pharmacological therapy for osteoporosis in postmenopausal women and men ≥70 years, with a previous fragility fracture, or a dose equivalent of prednisone ≥7.5 mg daily for ≥3 months. For premenopausal women and men <50 years taking steroids for ...
Platelet donation therapy is frequently needed by cancer patients, because chemotherapy for such patients can render them unable to generate platelets of their own. The basic principles of automatic platelet apheresis are the same as in the manual procedure, but the whole procedure is performed by a computer-controlled machine.
Thrombopoietin is a glycoprotein hormone produced by the liver and kidney which regulates the production of platelets. It stimulates the production and differentiation of megakaryocytes, the bone marrow cells that bud off large numbers of platelets. [5] Megakaryocytopoiesis is the cellular development process that leads to platelet production.
Platelet storage pool deficiency is a family of clotting disorders characterized by deficient granules in platelets. Individuals with these disorders have too few or abnormally functioning alpha granules , delta granules , or both alpha and delta granules and are therefore unable to form effective clots, which leads to prolonged bleeding.
