Idiopathic thrombocytopenic purpura (ITP) is a benign hematological disorder characterized by isolated thrombocytopenia. Development of antiplatelet autoantibodies is the main pathogenetic mechanism in patients with ITP. However the exact pathogenesis of ITP is complex in which megakaryocyte immune injury and T-cell mediated platelet destruction play significant role. Accordingly treatment of ITP relies mainly on immunosuppression. Recently triple regimen of high dose dexamethasone together with cyclosporine and rituximab was found to induce prolonged remission in patients with ITP compared with single agent immunosuppression. On the other hand this regimen suppresses all immune cells thus predisposing patient to serious infections, which is the main cause of morbidity in ITP furthermore infection enhances autoimmunity.
This study will focus on viral hepatitis C and B infection in Egyptian patients with idiopathic thrombocytopenic purpura on Triple therapy and aims to:
Blood born viral hepatitis is a type of viral hepatitis that is usually transmitted with transfusion of blood and blood products. Accordingly patients with hematological disorders are at higher risk for infection with blood born hepatitis as blood transfusion besides regular sampling are integral parts in management of hematological patients. This was the case in patients with ITP, however not all patients with ITP in need for regular platelet transfusion. The mainstay of treatment of ITP is immunosuppression, that was mainly dependent on parenteral or oral steroids for long time. Triple therapy was recently introduced for treatment of patients with ITP it induces strong immunosuppression that could make patients vulnerable to infections.
Several studies accused immunosuppression in patients with hematological malignancies under chemotherapy to be a risk factor for infection with blood born hepatitis, as such triple therapy could predispose patients with ITP to blood born viral hepatitis infection.
On the other hand infection with blood born hepatitis in patients with ITP on Triple therapy could affect patient outcome and response to treatment. This is because thrombocytopenia is a common extra hepatic manifestation of hepatitis C viral infection on its chronic form.
Egypt is a country with high prevalence of blood born viral hepatitis viral hepatitis C. Recently, the president of Egypt elaborated an initiative (100 million Health) that was managed with the Ministry of Health in all over the country. This initiative aimed to eliminate blood born hepatitis particularly C from the Country.
This work will be conducted in Egypt and focused on ITP patients on Triple therapy to assess their vulnerability for infection with blood born hepatitis as they are a particular sector of the Egyptian population at higher risk for infection.
