Acquired amegakaryocytic thrombocytopenic purpura - An underdiagnosed entity
Acquired Amegakaryocytic Thrombocytopenic Purpura (AATP) is a rare cause of thrombocytopenia presenting over a wide age group with symptoms of bleeding and bone marrow showing isolated absence of megakaryocytes in an otherwise normal marrow. Here, we report a case of AATP in a three year old female child who was then treated with anti thymocyte globulin successfully. We report this case because...
متن کاملAcquired amegakaryocytic thrombocytopenic purpura: a syndrome of diverse etiologies.
The possible pathogenetic mechanisms responsible for the production of acquired amegakaryocytic thrombocytopenic purpura (AATP) were investigated in a group of patients with this disorder. Absence of megakaryocytes and small platelet glycoprotein-bearing mononuclear cells, as determined by immunochemical staining of patient marrows with an antisera to platelet glycoproteins, suggested that the ...
متن کاملCell-mediated suppression of megakaryocytopoiesis in acquired amegakaryocytic thrombocytopenic purpura.
Acquired amegakaryocytic thrombocytopenic purpura (AATP) is a disorder of hematopoiesis characterized by severe thrombocytopenia due to a selective reduction or total absence of megakaryocytes in an otherwise normal-appearing bone marrow. Although the development of autoantibodies directed against cells in the megakaryocyte progenitor cell pool has been implicated in the pathogenesis of this di...
متن کاملCongenital amegakaryocytic thrombocytopenic purpura (CAMT).
Congenital amegakaryocytic thrombocytopenia (CAMT) is a rare, autosomal recessive disorder induced by mutations of the gene coding for thrombopoietin (TPO) receptor (c-MPL) despite high levels of serum TPO. Patients initially present with isolated thrombocytopenia that subsequently progresses into pancytopenia. Although the mechanisms leading to aplasia are unknown, the age of onset has been re...
متن کاملAcquired Thrombotic Thrombocytopenic Purpura in a Patient with Pernicious Anemia
Introduction. Acquired thrombotic thrombocytopenic purpura (TTP) has been associated with different autoimmune disorders. However, its association with pernicious anemia is rarely reported. Case Report. A 46-year-old male presented with blood in sputum and urine for one day. The vitals were stable. The physical examination was significant for icterus. Lab tests' results revealed leukocytosis, m...
