DIT results in TTP-like syndrome with hematologic phenotype of consumptive thrombocytopenia, microangiopathic hemolytic Anemia, and multiorgan dysfunction syndrome . A 31-year-old female with severe thrombotic thrombocytopenic purpura developed florid pulmonary edema after Rituximab infusion . TMA should be considered in all patients with thrombocytopenia and anaemia, with an immediate request to the haematology laboratory to look for red cell fragments on a blood film . Furthermore, increased S100B velocity seemed to be the earliest indicator of a refractory TTP disease process requiring more intensive plasma exchange (TPE) therapy regimen . We were able to confirm the presentation of the CUB2 domain-derived peptides FINVAPHAR and LIRDTHSLR on HLA-DR .
Typically managed with plasma exchange, Glucocorticoids, and the first-generation anti-CD20 monoclonal Antibody Rituximab, patients with multiple relapses or refractory disease present unique management challenges . Laboratory results showed normocytic normochromic anaemia, thrombocytopenia and evidence of TMA with decreased haptoglobin, elevated serum lactate dehydrogenase and a peripheral blood smear with numerous schistocytes . Antibodies anti-ADAMTS13 were positive, establishing the diagnosis of Acquired thrombotic thrombocytopenic purpura . Von Willebrand factor (VWF) multimer analyses showed absent high-molecular weight multimers . Many patients with acute myocardial infarction with thrombocytopenia have undergone percutaneous coronary intervention successfully with adjunctive antiplatelet and anticoagulant use, as has been described in case reports .
In recent years, several new diseases were identified, and by now 14 antigens targeted by IgG4 autoantibodies have been described . thrombotic thrombocytopenic purpura (TTP) is a life- threatening disease that can be related to various causes mainly autoimmune disorders or antineoplastic drugs . Few cases of TKI associated secondary thrombotic microangiopathies (TMA) have been reported in literature . Despite its frequent occurrence, thrombocytopenia often leads to difficulties of diagnosis and management in pregnancy . Typically, a pregnant Woman will have platelet counts of 150 000 to 450 000 per microlitre and platelet counts may be slightly lower than those of healthy, non-pregnant controls .
She was found to be Anemic, thrombocytopenic, and hypotensive . "aHUS" was considered and immediate plasma exchange was initiated . TMA should be considered in all patients with thrombocytopenia and anaemia, with an immediate request to the haematology laboratory to look for red cell fragments on a blood film . In this review, we have focused on some of the serious acquired causes of thrombocytopenia . There have been some significant advances in our understanding of the pathophysiology, diagnostic testing, and treatment of immune thrombocytopenia, heparin-induced thrombocytopenia, thrombotic thrombocytopenic purpura, and Atypical hemolytic uremic syndrome over the past five years .
Thrombotic microangiopathy (TMA), including hemolytic uremic syndrome (HUS) and thrombotic thrombocytopenic purpura (TTP) has also been reported as potential PRES inducer . The present study reviews two cases of patients with PRES, associated with TMA caused by Chemotherapy . Treatment with Steroids, plasma exchange, intravenous immunoglobulins, aspirin, antihypertensive drugs, and diuretics resulted in resolution of the neurological and imaging deficits . Treatment was ineffective and the patient deteriorated despite verapamil, dexamethasone, and plasma exchange . In this report, the relevant literature regarding pathogenesis, treatment and prognosis of chemotherapy-induced PRES associated with TMA was reviewed .
More severe thrombocytopenia in HIV-positive patients may reflect TMA in the setting of preexisting HIV-associated thrombocytopenia . The primary forms, thrombotic thrombocytopenic purpura (TTP) and hemolytic uremic syndrome (HUS), although their clinical presentations often overlap, have distinctive pathophysiologies . We present a case of a 21-year-old female with evidence of haemolytic anaemia based on the presence of positive markers of haemolysis . She was diagnosed with TTP and managed with emergency plasma exchange . 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) .
In a very uncommon condition designated thrombotic thrombocytopenic purpura (TTP), functional absence of ADAMTS13 tips the balance toward VWF-mediated platelet adhesion in the microcirculation . Microangiopathic hemolytic Anemia and thrombocytopenia were not severe in all patients . This case report describes treatment of refractory ITP with bortezomib, a proteasome inhibitor . This strategy has been successful in relapsing thrombotic thrombocytopenic purpura but is a novel therapeutic approach for ITP .
