چکیده

Immune thrombocytopenia (ITP) is a complex autoimmune disease characterized by low  platelet counts. The pathogenesis of ITP remains unclear although both antibody-mediated and/or  T cell-mediated platelet destruction are key processes. In addition, impairment of T cells, cytokine  imbalances, and the contribution of the bone marrow niche have now been recognized to be  important. Treatment strategies are aimed at the restoration of platelet counts compatible with  adequate hemostasis rather than achieving physiological platelet counts. The first line treatments  focus on the inhibition of autoantibody production and platelet degradation, whereas second-line  treatments include immunosuppressive drugs, such as Rituximab, and splenectomy. Finally, thirdline treatments aim to stimulate platelet production by megakaryocytes. This review discusses the  pathophysiology  of  ITP  and  how  the  different  treatment  modalities  affect  the  pathogenic  mechanisms.

Therapeutic Plasma Exchange in Pediatric Severe Immune Thrombocytopenia: A Case Report and Literature Review

Treatment of severe Immune Thrombocytopenic purpura (ITP) accompanied by life-threatening bleeding events is challenging and a combination of treatment measures should be undertaken to rapidly increase the platelet count. Herein, we report a case of severe ITP in a seven-year-old boy who suffered from massive bleeding which was totally unresponsive to conventional therapeutic interventions. Sin...

The Centenary of Immune Thrombocytopenia—Part 2: Revising Diagnostic and Therapeutic Approach

Primary immune thrombocytopenia (ITP) is the most common cause of thrombocytopenia in children and adolescents and can be considered as a paradigmatic model of autoimmune disease. This second part of our review describes the clinical presentation of ITP, the diagnostic approach and overviews the current therapeutic strategies. Interestingly, it suggests an algorithm useful for differential diag...

Immune thrombocytopenia in lymphoproliferative disorders.

Lymphoproliferative disorders are recognized as a common cause of secondary immune thrombocytopenia (ITP). The mechanisms involved in the pathogenesis of ITP associated with lymphoproliferative disorders are heterogeneous and often linked to the presence and activity of the malignant clone. A better understanding of the responsible mechanisms leading to ITP in each disease may allow for targete...

PROGRESS IN HEMATOLOGY Pathophysiology and management of thrombocytopenia: Possible clinical application of TPO receptor agonists Pathophysiology and management of primary immune thrombocytopenia

Primary immune thrombocytopenia, or idiopathic thrombocytopenic purpura (ITP), is an autoimmune disorder characterized by isolated thrombocytopenia due to accelerated platelet destruction and impaired platelet production. Autoantibodies against platelet surface glycoproteins, such as GPIIb/IIIa and GPIb/IX complexes, play major roles in both platelet destruction and impaired platelet production...

Prednison provokes serum and vasoactive substances in a mice model of immune thrombocytopenia

Objective(s): The main objective of this study was to investigate the variations of β-endorphin (β-EP), vasoactive intestinal peptide (VIP), serotonin (5-HT) and norepinephrine (NE) of immune thrombocytopenia (ITP) mice as well as the regulatory mechanism of prednison. Materials and Methods: Sixty BALB/c mice were randomly divided into control group, model group and prednison intervention grou...

The Centenary of Immune Thrombocytopenia – Part 1: Revising Nomenclature and Pathogenesis

The natural history of the immune thrombocytopenia (ITP) is interesting and intriguing because it traces different steps underlying autoimmune diseases. The review points out the main steps that have accompanied the stages of its history and the consequential changes related to its terminology. ITP is an autoimmune disease resulting from platelet antibody-mediated destruction and impaired megak...
