Male (NZW X BXSB)F1 (W/BF,) mice develop systemic autoimmunity involving autoantibodies, progressive thrombocytopenia, lupus nephritis, and degenerative coronary vascular disease with myocardial infarction. Plateletassociated IgG (PAIgG) on the platelet surface mediates platelet destruction by the reticuloendothelial system in the autoimmune thrombocytopenic purpura (ATP) of W/ BF1 mice. Becaus...

UNLABELLED Thrombocytopenia and oxidative stress are the most frequent problems in patients with chronic liver diseases as viral cirrhosis and schistosomiasis. So, this study aimed to evaluate the role of thrombopoietin (TPO) on the occurrence of thrombocytopenia and in differentiation between these diseases. It also aimed to investigate the relation between TPO, oxidative stress and antioxidan...

We studied the extent to which patient characteristics influenced outcome in childhood idiopathic thrombocytopenic purpura in a historical cohort of 289 children over a 20 year period (1968-87). Outcome was classified as acute or chronic depending on whether the platelet count had returned to normal (150 X 10(9)/l) by six months after diagnosis. Fifty three cases (18%) had chronic idiopathic th...

Immune thrombocytopenic purpura is an autoimmune disease characterized by auto-antibody induced platelet destruction and reduced platelet production, leading to low blood platelet count. In this case report, the clinical diagnose of a patient with immune thrombocytopenic purpura and spontaneous gingival hemorrhage by a dentist is presented. The patient did not have any systemic disease that wou...

Background: Determining the prevalence and risk factors of thrombocytopenia among neonates enables us to prevent the inevitable and sometimes irreversible complications. In this study we aimed to survey the frequency of thrombocytopenia and its demographic features and risk factors. Materials and methods: In this cross sectional study the platelet counts of 364 neonates admitted to neonatal ...

The treatment of thrombotic thrombo-cytopenic purpura with exchange transfusions, plasma infusions, and plasma exchange. multicenter survey and retrospective analysis of current efficacy of therapeutic plasma exchange. The thrombotic thrombocytopenic purpura and hemolyt-ic uremic syndromes: evaluation, management, and long-term out-et al. ADAMTS13 activity in thrombotic thrombocytopenic purpura...

Metastatic pancreatic adenocarcinoma presenting with immune thrombocytopenic purpura is a very rare association. To date, only 1 case report found in the literature delineates such an association. We present a case of a patient with newly diagnosed, biopsy-proven metastatic pancreatic adenocarcinoma with new-onset immune thrombocytopenic purpura. The patient's platelet count returned to normal ...

Thrombotic thrombocytopenic purpura is a rare thrombotic disease characterized by episodes of thrombocytopenia and microangiopathic hemolytic anemia due to disseminated microvascular thrombosis. Thrombotic thrombocytopenic purpura was first described in 1924 by Moschowitz as a disease presenting with a pentad of signs and symptoms (anemia, thrombocytopenia, fever, hemiparesis and hematuria). Pr...

Two brothers and one sister had three variants of thrombotic thrombocytopenic purpura and haemolytic uraemic syndrome (the 'TTP-HUS' complex). The sister had a chronic fatal variant of thrombotic thrombocytopenic purpura with severe neurological manifestation. One brother had a chronic relapsing disease but the kidneys were not affected, and the other brother had haemolytic uraemic syndrome. Th...
