Platelet inventory management based on screening microparticle content in platelet concentrates is a new quality improvement initiative for hospital blood banks. Cells fragment off microparticles (MP) when they are stressed. Blood and blood components may contain cellular fragments from a variety of cells, most notably from activated platelets. When performing their roles as innate immune cells and major players in coagulation and hemostasis, platelets change shape and generate microparticles. With dynamic light scattering (DLS)-based microparticle detection, it is possible to differentiate activated (high microparticle) from non-activated (low microparticle) platelets in transfusions, and optimize the use of this scarce blood product...

Administering the wrong blood component to the wrong patient can have serious clinical consequences, including death. Patients have a right to safe clinical practice in line with nurses' professional standards and code of conduct, and other healthcare regulatory frameworks. Transfusion of blood components is no exception to this; therefore, it is important for healthcare organisations to have policies in place to support healthcare practitioners in ensuring patient safety throughout the transfusion process...

BACKGROUND: Haemorrhagic shock remains the leading cause of preventable death in overseas and austere settings. Transfusion of blood components is critical in the management of this kind of injury. For French naval and ground military units, this supply often takes too long considering the short shelf-life of red blood cell concentrates (RBCs) and the limited duration of transport in cooling containers (five to six days). Air-drop supply could be an alternative to overcome these difficulties on the condition that air-drop does not cause damage to blood units...

We present the case of a 67-year-old man who suffered an acute anaphylactic reaction during red cell transfusion due to the presence of anti-IgA antibodies. The incidence and clinical relevance of anti-IgA antibodies in IgA deficiency is reviewed, and the wider investigation and management of acute transfusion reactions is also discussed. This case highlights the need to consider the potential risks of blood component transfusion against the purported benefit.

Leukoreduction in blood units could prevent patients undergoing transfusions from transfusion-associated adverse reactions (TAARs) such as febrile nonhemolytic transfusion reactions (FNHTRs). However, the effect of prestorage and poststorage leukoreduction on TAARs and its underlying mechanisms in stored blood components remains to be determined. Therefore, we investigated the impact of prestorage leukocyte-reduced (pre-LR) and poststorage leukocyte-reduced (post-LR) blood products, including red blood cells (RBCs) and apheresis platelets (PHs), on the incidence of FNHTRs and other TAARs in patients who received transfusions from 2009 to 2014 in a tertiary care center...

OBJECTIVE: Erythrocyte storage induces a non-physiological increase in hemoglobin-oxygen affinity (quantified by low p50, the oxygen tension at 50% hemoglobin saturation), which can be restored through biochemical rejuvenation. The objective was to mathematically model the impact of transfusing up to three standard allogeneic units or rejuvenated units on oxygen delivery (DO 2 ) and oxygen consumption (VO 2 ). METHODS: Oxygen dissociation curves were generated from AS-1 RBC leukoreduced units (n = 7) before and after rejuvenation following manufacturer's instructions...

PURPOSE OF REVIEW: The purpose of this review is to highlight the role of hemoglobin in cerebral physiology and pathophysiology. We review the existing as well as recent evidence detailing the effects of red blood cell transfusion on cerebral oxygenation and clinical outcome. RECENT FINDINGS: Hemoglobin is a key component in oxygen delivery, and thus cerebral oxygenation. Higher hemoglobin levels and red blood cell transfusion are associated with higher cerebral oxygen delivery and decreased cerebral ischemic burden...

HEV infections are mainly food- and water-borne but transfusion-transmission has occurred in both developing and developed countries. The infection is usually asymptomatic but it can lead to fulminant hepatitis in patients with underlying liver disease and pregnant women living in developing countries. It also causes chronic hepatitis E, with progressive fibrosis and cirrhosis, in approximately 60 % of immunocompromised patients infected with HEV genotype 3. Extra-hepatic manifestations such as neurological and renal manifestations have been reported...

OBJECTIVES: Transfusion-related acute lung injury is characterized by the onset of respiratory distress and acute lung injury following blood transfusion, but its pathogenesis remains poorly understood. Generally, a two-hit model is presumed to underlie transfusion-related acute lung injury with the first hit being risk factors present in the transfused patient (such as inflammation), whereas the second hit is conveyed by factors in the transfused donor blood (such as antileukocyte antibodies)...

BACKGROUND: In an environment of limited health care resources, it is crucial for health care systems which provide blood transfusion to have accurate and comprehensive information on the costs of transfusion, incorporating not only the costs of blood products, but also their administration. Unfortunately, in many countries accurate costs for administering blood are not available. Our study aimed to generate comprehensive estimates of the costs of administering transfusions for the UK National Health Service...

BACKGROUND: Minimising perioperative bleeding is a key goal of "patient blood management" programs. One component of respective strategies includes preventive inhibition of fibrinolysis using protease inhibitors, such as tranexamic acid (TXA). TXA inhibits plasminogen activation and plasmin-induced fibrin degradation. OBJECTIVES: The present article provides an overview of the existing literature and TXA applications in the prophylaxis of perioperative bleeding...

REVIEW
Louise I Ainley, Patricia E Hewitt
A 2014 study by NHS Blood and Transplant indicated that over one quarter of red cells were transfused to patients with haematological conditions. For platelet components, the figure is higher. Certain diagnostic groups, such as haemoglobinopathies, myelodysplastic syndromes and some haemato-oncology patients, receive multiple transfusion episodes, either over long periods, or more intensively over shorter periods. Haematology patients account for the majority of the multi-transfused population. The risk of transfusion-transmitted infection (TTI) increases with number of donor exposures, and the consequences of TTI are often more significant in immunosuppressed individuals...

BACKGROUND: Emerging transfusion-transmissible pathogens, including arboviruses such as West Nile, Zika, dengue, and Ross River viruses, are potential threats to transfusion safety. The most prevalent arbovirus in humans in Australia is Ross River virus (RRV); however, prevalence varies substantially around the country. Modeling estimated a yearly risk of 8 to 11 potentially RRV-viremic fresh blood components nationwide. This study aimed to measure the occurrence of RRV viremia among donors who donated at Australian collection centers located in areas with significant RRV transmission during one peak season...

BACKGROUND: Transfusion-transmitted malaria (TTM) is an accidental Plasmodium infection caused by whole blood or a blood component transfusion from a malaria infected donor to a recipient. Infected blood transfusions directly release malaria parasites in the recipient's bloodstream triggering the development of high risk complications, and potentially leading to a fatal outcome especially in individuals with no previous exposure to malaria or in immuno-compromised patients. A systematic review was conducted on TTM case reports in non-endemic areas to describe the epidemiological characteristics of blood donors and recipients...
