Primary immune thrombocytopenic purpura (ITP), also referred to as idiopathic thrombocytopenic purpura, is an organ-specific autoimmune disorder in which antibody-coated or immune complex-coated platelets are destroyed prematurely by the reticuloendothelial system, resulting in peripheral blood thrombocytopenia. The disease is heterogeneous with regard to its severity and clinical course and is...

OBJECTIVE To determine the association of Helicobacter pylori infection in patients presenting with idiopathic thrombocytopenic purpura (ITP). METHODS From March 2007 to March 2008, thirty adult patients with ITP and 30 age and sex matched healthy controls were investigated for the presence of H. pylori infection by Helicobacter pylori stool antigen (HpSA) an enzyme immunoassay (EIA) based me...

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...

Immunoglobulins (Igs) and serum albumin were eluted from normal platelets and platelets from patients with idiopathic thrombocytopenic purpura (ITP) with a quantitative acid elution procedure followed by solid-phase radioimmunoassay (SPRIA). Acid elution was shown to release a reproducible fraction of platelet-associated Igs, and the amounts released per platelet were independent of the platele...

Background: Idiopathic thrombocytopenic purpura is an autoimmune blood disorder in which platelet destruction is mediated by anti-platelet antibodies. There are two forms of ITP: acute and chronic. The aim of the present study was to evaluate the clinical variables in adult patients with acute ITP in west of Iran. Patients and Methods: Medical records of adult patients with diagnosis of acute ...

OBJECTIVE Immune thrombocytopenic purpura (ITP) is also known as idiopathic thrombocytopenic purpura. Increased platelet destruction and insufficient platelet production are both responsible for its etiopathogenesis. ITP can be diagnosed after excluding other possible causes of thrombocytopenia. MATERIALS AND METHODS One hundred forty-three cases of chronic ITP that were monitored in a hemato...

First-line therapies of acute and chronic idiopathic thrombocytopenic purpura (ITP) include intravenous immunoglobulin, IV anti-D and corticosteroids. A short-course high-dose dexamethasone (HDD-SC) therapy has recently been reported to be efficacious in acute ITP. The present study was conducted to assess the efficacy of HDD-SC in children with chronic ITP. Over a period of 10 months, 13 patie...
