IRVINE, Calif., April 5 /PRNewswire-FirstCall/ -- A new blood transfusion cost analysis study published in the April 2010 issue of Transfusion, a peer-reviewed academic journal, shows that when all of the complex cost factors leading up to and after a red blood cell (RBC) transfusion are considered, the actual cost of blood is substantially higher than previously estimated. With actual blood transfusion costs ranging between $522 and $1,183 per-unit--37% higher than estimated by prior...

Sideroblastic anemia is a form of anemia caused by an inability to incorporate iron into hemoglobin, something that is essential if the molecule is to perform its vital function of carrying oxygen from the lungs to the tissues. Recently, a patient with sideroblastic anemia was found to have a mutation in their GLRX5 gene that led to GLRX5 protein deficiency. Tracey Rouault and colleagues, at the National Institute of Child Health and Human Development, Bethesda, have now provided insight into...

IRVINE, Calif., Feb. 18 /PRNewswire-FirstCall/ -- A comparison study of nearly 1,900 patients published in Perfusion, a peer-reviewed academic journal, questions the long-standing practice of basing blood transfusion decisions on a single low hematocrit measurement result. In the study, titled Is it the Patient or the Physician who Cannot Tolerate Anemia?, researchers showed that a single measure of hematocrit is not a reliable indicator of transfusion need and that lower-than-normal...

A set of proteins found in our intestines can recognize and kill bacteria that have human blood type molecules on their surfaces, scientists at Emory University School of Medicine have discovered. The results were published online Feb. 14 and are scheduled to appear in the journal Nature Medicine. Many immune cells have receptors that respond to molecules on the surfaces of bacteria, but these proteins are different because they recognize structures found on our own cells, says senior author...

Scientists at Washington University School of Medicine in St. Louis have identified a protein made by the malaria parasite that is essential to its ability to take over human red blood cells. Malaria, which is spread by mosquito bites, kills between 1 million and 3 million people annually in Third World countries. Death results from damage to red blood cells and clogging of the capillaries that feed the brain and other organs. "The malaria parasite seizes control of and remodels the red blood...

Promising results in mice could prevent fatal iron buildup in humans A new study shows that a protein found in blood alleviates anemia, a condition in which the body's tissues don't get enough oxygen from the blood. In this animal study, injections of the protein, known as transferrin, also protected against potentially fatal iron overload in mice with thalassemia, a type of inherited anemia that affects millions of people worldwide. Implications of the study, published in the January 24...

Much like a tightly wound drum, red blood cells are in perpetual vibration. Those vibrations help the cells maintain their characteristic flattened oval or disc shape, which is critical to their ability to deform as they traverse blood vessels in the body to deliver oxygen to tissues. Blood disorders such as malaria, sickle cell anemia and spherocytosis interfere with those vibrations, so a better understanding of the vibrations could help researchers develop treatments for those diseases....
