BACKGROUND Heparin-induced thrombocytopenia is caused by antibody formation to heparin-platelet factor 4 complexes. It typically develops 5 to 14 days after the initiation of heparin, but it can occur up to 3 weeks after the patient stops taking it. Early recognition by monitoring platelet counts during heparin therapy can decrease associated mortality and morbidity. METHODS A case is describ...

Drug-induced immune thrombocytopenia (DITP), excluding heparin-induced thrombocytopenia, is relatively uncommon. It is characterized by drug-dependent antibodies that bind to the platelets and cause their destruction when the responsible drug is ingested or injected. Imipramine is a tricyclic antidepressant drug that is one of those used widely for primary enuresis nocturna, attention deficit h...

Megakaryocyte growth and development factor (MGDF) administered intraperitoneally (IP) to mice causes a dose-dependent thrombocytosis accompanied by a decrease in mean platelet volume. MGDF increases the number of megakaryocytes in the bone marrow and spleen. MGDF does not affect the circulating number of leukocytes. Carboplatin, a chemotherapeutic agent that causes thrombocytopenia in humans, ...

Acute thrombocytopenia and megakaryocyte infection have been investigated during the preleukemic phase of the disease induced by the Rauscher murine leukemia virus (RMuLV) in mice. Injection of RMuLV, either intravenously or intraperitoneally, rapidly induced thrombocytopenia, possibly as a result of direct interaction between platelets and viral particles. The susceptibility to this acute thro...

The use of heparin have increased in the last years in hospitalized both as prophylaxis and therapeutic. One of the encounter complications of heparin especially with unfractionated heparin though it can be seen with Low molecular weight heparin is thrombocytopenia which could be transient non immune or more badly the immune mediated type heparin induced thrombocytopenia (HIT). Heparin-induced ...

Thrombocytopenia is a common hematologic disorder. Stimulation of thrombopoiesis may reduce the risk for thrombocytopenia-induced bleeding, prevent severe thrombocytopenia, and reduce the need for platelet transfusion. The key cytokine is thrombopoietin (TPO). It regulates proliferation and maturation of megakaryocytes as well as platelet production. TPO is synthesized in the liver. Development...
