OBJECTIVE Blood loss and moderate anemia are common in patients with traumatic brain injury (TBI). However, despite evidence of the ill effects and expense of the transfusion of packed red blood cells, restrictive transfusion practices have not been universally adopted for patients with TBI. At a Level I trauma center, the authors compared patients with TBI who were managed with a restrictive (target hemoglobin level > 7 g/dl) versus a liberal (target hemoglobin level > 10 g/dl) transfusion protocol. This study evaluated the safety and cost-efficiency of a hospital-wide change to a restrictive transfusion protocol...

BACKGROUND: Red blood cell (RBC) Thomsen-Friedenreich antigen exposure (T activation) in infants with necrotizing enterocolitis (NEC) has occasionally been associated with posttransfusional intravascular hemolysis thought to be due to anti-T antibodies in the donor plasma. STUDY DESIGN AND METHODS: We describe an infant with NEC and Clostridium perfringens infection complicated by severe hemolysis after plasma transfusion. After this case, infants with confirmed NEC were prospectively evaluated for T activation...

BACKGROUND: Transfusion data for obstetric patients are scarce. Identifying characteristics associated with red blood cell transfusion (RBCT) is of importance to better identify patients who would benefit from blood conservation strategies as the risk of alloimmunization from RBCT has the potential to affect the fetus and newborn. STUDY DESIGN AND METHODS: We conducted a retrospective cohort study using hospital administrative data to identify trends and risk factors of RBCT in obstetric patients...

Transfusion medicine plays a vital role in the supportive care of patients receiving therapy for hematology, oncology and hematopoietic stem cell transplants (HSCT). With advances in therapy with more intensive chemotherapy or radiotherapy, patients usually develop cytopenias and need frequent transfusion support with packed red blood cells, granulocyte transfusion or platelets to support them until they recover from the effect of therapy. HSCT poses unique challenges for transfusion medicine, since transplant recipients may require substantial transfusion support due to cytopenias associated with toxic medications, decreased marrow reserve, infection or their malignancy...

BACKGROUND: Red blood cell (RBC) transfusions are commonly used in surgical patients, but accompanied by many risks such as metabolic derangement, and allergic and febrile reactions. Indications for transfusion in patients after hip or knee surgery have not been definitively evaluated and remain controversial. We performed a meta-analysis to compare the benefits and harms of restrictive versus liberal transfusion strategies in patients after hip or knee surgery. METHODS: The PubMed, EMBASE, and Cochrane Library databases were searched for relevant studies through September 2015...

BACKGROUND: Identifying trauma patients that need emergent blood product transfusion is crucial. The Trauma Induced Coagulopathy Clinical Score (TICCS) is an easy-to-measure score developed to meet this medical need. We hypothesized that TICCS would assist in identifying patients that need a transfusion in a large cohort of severe trauma patients from the TraumaRegister DGU(®) (TR-DGU). MATERIALS AND METHODS: A total of 33,385 severe trauma patients were extracted from the TR-DGU for retrospective analysis...

BACKGROUND: Alloimmunization to red blood cells (RBCs) can cause serious transfusion reactions and complicate the search for compatible blood products. Alloantibodies can be detected for periods ranging from a few days to several years, yet the mechanisms controlling the duration of detectability remain unknown. We studied the detection durations in patients forming multiple antibodies to investigate whether the duration is more strongly determined by conditions present at the time of each transfusion (peritransfusion factors) or by more stable patient-specific factors likely to persist across transfusions...

BACKGROUND: Red blood cell distribution width (RDW) has been shown to predict mortality in critically ill patients. To our knowledge, whether or not RDW is associated with clinical outcomes of obstetric patients requiring critical care has not been evaluated. METHODS: This was a single centre, retrospective, observational study of obstetric patients admitted to the intensive care unit (ICU). Patients were excluded from the analysis if they had known haematological diseases or recently underwent blood transfusion...

During RBC transfusion, production of alloantibodies against RBC non-ABO Ags can cause hemolytic transfusion reactions and limit availability of compatible blood products, resulting in anemia-associated morbidity and mortality. Multiple studies have established that certain inflammatory disorders and inflammatory stimuli promote alloimmune responses to RBC Ags. However, the molecular mechanisms underlying these findings are poorly understood. Type I IFNs (IFN-α/β) are induced in inflammatory conditions associated with increased alloimmunization...

BACKGROUND: Postpartum hemorrhage remains the leading cause of maternal morbidity and mortality worldwide. Few population-based studies have examined the epidemiology of massive transfusion for postpartum hemorrhage. The aim of this study was to determine the incidence, management, and outcomes of women with postpartum hemorrhage who required massive transfusion in the Netherlands between 2004 and 2006. METHODS: Data for all women from a gestational age of 20 weeks onwards who had postpartum hemorrhage requiring eight or more red blood cell concentrates were obtained from a nationwide population-based cohort study including all 98 hospitals with a maternity unit in the Netherlands...

We report a case of paroxysmal nocturnal hemoglobinuria (PNH) in a 14 year-old girl presenting a cerebral arterial thrombosis. The initial diagnosis was carential anemia due to menarche following identification of slight macrocytic anemia, leucopenia and mild thrombocytopenia at routine blood analysis. The child was eventually referred to a children's hospital after the onset of progressive fatigue, anorexia and paleness. Severe anemia (hemoglobin 6 g/dL) with negative Coombs test, mild leucopenia (white blood cells 4...

BACKGROUND: Currently, there is an extensive but highly inconsistent body of literature regarding donor adverse events (AEs) in haemapheresis. As the reports diverge with respect to types and grading of AEs, apheresis procedures and machines, the range of haemapheresis-related AEs varies widely from about 0.03% to 6.6%. METHODS: The German Society for Transfusion Medicine and Immunohaematology (DGTI) formed a 'Haemapheresis Vigilance Working Party' (Arbeitsgemeinschaft Hämapheresevigilanz; AGHV) to create an on-line registry for comprehensive and comparable AE assessment with all available apheresis devices in all types of preparative haemapheresis: plasmapheresis (PLS), plateletpheresis (PLT), red blood cell apheresis, all kind of leukaphereses (autologous/allogeneic blood stem cell apheresis, granulocyte apheresis, lymphocyte/monocyte apheresis) and all possible types of multi-component apheresis...

BACKGROUND: The ex vivo generation of human hematopoietic stem cells (HSCs) with long-term repopulating capacity and multi-lineage differentiation potential represents the holy grail of hematopoiesis research. In principle, human induced pluripotent stem cells (hiPSCs) provide the tool for both studying molecular mechanisms of hematopoietic development and the ex vivo production of 'true' HSCs for transplantation purposes and lineage-specific cells, e.g. red blood cells, for transfusion purposes...
