Patients with diabetes, kidney disease and anemia who don't respond to treatment with an anti-anemia drug have a higher risk of cardiovascular disease or death, researchers at UT Southwestern Medical Center have found. The results suggest that testing such patients' responsiveness to the drug and keeping blood iron levels a little low might reduce their risk, said Dr. Robert Toto, professor of internal medicine and clinical sciences and a senior author of the study, which appeared in the New...

Although the incidence of malaria has declined in all but a few countries worldwide, according to a World Health Organization report earlier this month, malaria remains a global threat. Nearly 800,000 people succumbed to the mosquito-borne disease in 2009, nearly all of them in the developing world. Physicians do not have reliable treatment for the virus at various stages, largely because no one has been able to document the malaria parasite's journeys in the body. Now researchers at Brown...

Staphylococcus aureus bacteria bind best to human hemoglobin"Staph" bacteria feed on blood. They need the iron that's hidden away inside red blood cells to grow and cause infections. It turns out that these microbial vampires prefer the taste of human blood, Vanderbilt University scientists have discovered.The researchers report in the Dec. 16 issue of Cell Host & Microbe that Staphylococcus aureus (staph) favors human hemoglobin "“ the oxygen-carrying protein that contains iron...

Red blood cells (RBCs) have the very important role of carrying oxygen from the lungs to the rest of the body; therefore, disorders that affect RBCs can have a significant impact on quality of life. Sickle cell disease and malaria are two common RBC diseases that affect a significant portion of the U.S. and global populations. Sickle cell disease (SCD), a genetic blood disorder that causes deformed and dysfunctional red blood cells, affects an estimated 70,000 to 100,000 Americans,1 while...

(Ivanhoe Newswire) -- As if high blood pressure, chronic diseases, and cancer weren't enough, high levels of erythropoietin in people over 85 join the list of silent killers. Erythropoietin is a hormone created in the kidneys to stimulate production of red blood cells. Production is triggered by impaired oxygen delivery to the kidney because of anemia or low blood oxygen levels. Studies involving patients with chronic heart failure have shown that high erythropoietin levels predict poor...

A UCSF-led team has discovered at least one key reason why blood stem cells are susceptible to developing the genetic mutations that can lead to adult leukemia. Their finding also may explain, they say, why some other age-related hematological disorders develop. The study, reported in "Cell Stem Cell" (Aug. 6, 2010) and reviewed in Cell Stem Cell and Cell, opens a new frontier for studying the molecular underpinnings of adult leukemia. The discovery also suggests a possible therapeutic...
