Randomized Controlled Trial Comparative Study
Large-dose intravenous ferric carboxymaltose injection for iron deficiency anemia in heavy uterine bleeding: a randomized, controlled trial.
The objective was to evaluate efficacy and safety of rapid, large-dose intravenous (IV) administration of ferric carboxymaltose compared to oral iron in correcting iron deficiency anemia due to heavy uterine bleeding. ⋯ In patients with iron deficiency anemia due to heavy uterine bleeding, rapid IV administration of large doses of a new iron agent, ferric carboxymaltose, is more effective than oral iron therapy in correcting anemia, replenishing iron stores, and improving quality of life.

Risks of transfusion-transmitted infections (TTIs), transfusion-associated sepsis (TAS), and transfusion-related acute lung injury (TRALI) were compared between pooled whole blood-derived (PWBD) and single-donor platelets (PLTs) transfused in the United States. ⋯ TTIs and TAS determine the relative safety of PWBD versus single-donor PLTs. The available limited data do not support a higher risk of TRALI from single-donor (compared with PWBD) PLTs.

Most cases of human babesiosis in North America are caused by Babesia microti, which is endemic in the northeastern and upper midwestern United States. Although the disease is usually transmitted by a tick bite, there has been an increase in the number of transfusion-transmitted cases reported. We describe a fatal case of transfusion-transmitted babesiosis in a nonendemic state, Delaware. ⋯ We believe that this is the first reported case of transfusion-transmitted babesiosis in Delaware, a nonendemic state. Our case illustrates that clinicians should consider babesiosis in the differential diagnosis of immunocompromised patients who have fever and recent transfusion history, even in areas where babesiosis is not endemic. It also demonstrates the need for better preventive strategies including more sensitive, specific, and rapid blood donor screening tests to prevent transfusion-transmitted babesiosis.

Babesia microti, the primary cause of human babesiosis in the United States, is an intraerythrocytic parasite endemic to the Northeast and upper Midwest. Published studies indicate that B. microti increasingly poses a blood safety risk. The American Red Cross Hemovigilance Program herein describes the donor and recipient characteristics of suspected transfusion-transmitted B. microti cases reported between 2005 and 2007. ⋯ Transfusion-transmitted B. microti can be a significant cause of transfusion-related morbidity and mortality, especially in infant, elderly, and asplenic blood recipients. These data demonstrate the need for interventions, in both endemic and nonendemic areas of the United States, to reduce patient risk.

Excessive use of blood components during liver transplantation should be avoided because it has been associated with poor outcomes and it may stress blood bank resources. ⋯ Liver donor's age and recipient's SCr are important in preoperatively predicting blood use during liver transplantation.
