Introduction. Hypertransfusion refers to chronic blood transfusion therapy aimed at ameliorating disease complications in various haemopathies particularly the haemoglobinopathies. In sickle cell disease, hypertransfusion is aimed at maintaining patient's haemoglobin level at 10 to 11 g/dL using haemoglobin AA blood and its resultant dilutional effect on sickle haemoglobin is sustained by inter...

Hereby we report a patient with thalassemia major having extradural cord compression at T3-T9 levels due to a mass of extramedullary hematopoiesis (EMH) tissue, whose treatment was successful with hypertransfusion therapy alone. The patient was a 23-year-old man who had not received regular blood transfusion since two years before admission. He suffered from paraparesis with a history of progre...

BACKGROUND This study aimed to determine the potential protective effect of inducing hypertransfusion to the gastrointestinal tract following a porcine model of cardiac arrest and cardiopulmonary resuscitation (CPR) by evaluating the influence of gastrointestinal ultrastructure, ATPase and serum diamine oxidase. METHODS Ventricular fibrillation was induced by programmed electrical stimulation...

Megakaryocytopoiesis in the spleens of lethally irradiated mice transplanted with marrow cells was suppressed by platelet transfusions. In one group of experiments, animals were irradiated and transfused with bone marrow cells on day O. They were then given either no treatment, platelets, platelet-poor plasma, or saline on days 0, 2, 4, 6, and 8, and then were sacrificed on day 10. Megakaryocyt...

The bioassay of erythropoietin in animals is reviewed. The techniques employed are those of hypertransfusion and hypoxia using polycythemic mice.

hereby we report a patient with thalassemia major having extradural cord compression at t3-t9 levels due to a mass of extramedullary hematopoiesis (emh) tissue, whose treatment was successful with hypertransfusion therapy alone. the patient was a 23-year-old man who had not received regular blood transfusion since two years before admission. he suffered from paraparesis with a history of progre...

Hypertransfusion can enhance myeloid recovery after bone marrow depletion, but its influence on thrombopoietic recovery has not been previously defined. We have studied the pattern of platelet and megakaryocyte recovery in mice hypertransfused after receiving 350 rad whole body irradiation. The platelet counts of the hypertransfused group showing an initial fall due to hemodilution in the expan...

Thalassemia major (beta-thalassemia) affects a significant segment of the population in certain areas of the world. Alterations in migration patterns have changed the geographic distribution of this disease and made it a worldwide health problem. Over the course of the past 2-3 decades hypertransfusion therapy has significantly increased the life expectancy, and improved the quality of life of ...
