    Current misconceptions in diagnosis and management of iron deficiency.
    Blood Transfus 2017 Sep;15(5):422-437
    Georgetown University School of Medicine, Washington, DC, United States of America.
    The prevention and treatment of iron deficiency is a major public health goal. Challenges in the treatment of iron deficiency include finding and addressing the underlying cause and the selection of an iron replacement product which meets the needs of the patient. However, there are a number of non-evidence-based misconceptions regarding the diagnosis and management of iron deficiency, with or without anaemia, as well as inconsistency of terminology and lack of clear guidance on clinical pathways.

    The role of recombinant activated factor VII in the haematological management of elective orthopaedic surgery in haemophilia A patients with inhibitors.
    Blood Transfus 2017 Sep 16;15(5):478-486. Epub 2017 May 16.
    Centre for Bleeding Disorders and Coagulation, Department of Oncology, "Careggi" University Hospital, Florence, Italy.
    The clinical profile and expectations of haemophilic patients with inhibitors have changed over the last three decades, mainly because of the prolongation of life-expectancy, often resulting in an increase of the orthopaedic burden. Recombinant activated factor VII (rFVIIa) is the most frequently used bypassing agent in haemophilia patients with inhibitors during elective orthopaedic surgery. For nearly 30 years, rFVIIa has been successfully used to control haemostasis in several major and minor surgical procedures. Read More

    Department of Medicine, Thrombotic and Haemorrhagic Diseases Unit, University of Padua Medical School, Padua, Italy.
    Background: The Italian Registry of Thrombosis in Children (RITI) was established by a multidisciplinary team with the aims of improving knowledge about neonatal and paediatric thrombotic events in Italy and providing a preliminary source of data for the future development of specific clinical trials and diagnostic-therapeutic protocols.

    Materials And Methods: We analysed the subset of RITI data concerning paediatric systemic venous thromboembolic events that occurred between January 2007 and June 2013.

    Results: Eighty-five deep venous thromboses and seven pulmonary emboli were registered in the RITI. Read More

    Influence of red blood cell-derived microparticles upon vasoregulation.
    Blood Transfus 2017 May 15:1-13. Epub 2017 May 15.
    Department of Pediatrics, Washington University, St. Louis, MO, United States of America.
    Here we review recent data and the evolving understanding of the role of red blood cell-derived microparticles (RMPs) in normal physiology and in disease progression. Microparticles (MPs) are small membrane vesicles derived from various parent cell types. MPs are produced in response to a variety of stimuli through several cytoskeletal and membrane phospholipid changes. Read More

    Washing in hypotonic saline reduces the fraction of irreversibly-damaged cells in stored blood: a proof-of-concept study.
    Blood Transfus 2017 Sep 11;15(5):463-471. Epub 2017 May 11.
    Department of Biomedical Engineering, University of Houston, TX, United States of America.
    Background: During hypothermic storage, a substantial fraction of red blood cells (RBCs) transforms from flexible discocytes to rigid sphero-echinocytes and spherocytes. Infusion of these irreversibly-damaged cells into the recipient during transfusion serves no therapeutic purpose and may contribute to adverse outcomes in some patients. In this proof-of-concept study we describe the use of hypotonic washing for selective removal of the irreversibly-damaged cells from stored blood. Read More

    Individual, contextual and network characteristics of blood donors and non-donors: a systematic review of recent literature.
    Blood Transfus 2017 Sep 13;15(5):382-397. Epub 2017 Jun 13.
    Department of Donor Studies, Sanquin Research, Vrije Universiteit, the Netherlands.
    Background: The ageing population and recent migration flows may negatively affect the blood supply in the long term, increasing the importance of targeted recruitment and retention strategies to address donors. This review sought to identify individual, network and contextual characteristics related to blood donor status and behaviour, to systematically discuss differences between study results, and to identify possible factors to target in recruitment and retention efforts.

    Methods: The systematic review was conducted in accordance with a predefined PROSPERO protocol (CRD42016039591). Read More

    Enhanced opsonisation of Rhesus D-positive human red blood cells by recombinant polymeric immunoglobulin G anti-G antibodies.
    Blood Transfus 2017 May 30:1-9. Epub 2017 May 30.
    Cellular and Molecular Pathology Laboratory, Experimental Medicine Centre, Venezuelan Institute of Scientific Investigation (IVIC), Caracas, Venezuela.
    Background: Anti-RhD antibodies (anti-D) are important in the prophylaxis of haemolytic disease of the foetus and newborn (HDFN) due to RhD incompatibility. Current preparations of anti-D are sourced from hyperimmune human plasma, so its production carries a risk of disease and is dependent on donor availability. Despite the efforts to develop a monoclonal preparation with similar prophylactic properties to the plasma-derived anti-D, no such antibody is yet available. Read More

    Improving the safety of whole blood-derived transfusion products with a riboflavin-based pathogen reduction technology.
    Blood Transfus 2017 Jul 11;15(4):357-364. Epub 2017 May 11.
    Terumo BCT Europe N.V., Zaventem, Belgium.
    Worldwide safety of blood has been positively impacted by technological, economic and social improvements; nevertheless, growing socio-political changes of contemporary society together with environmental changes challenge the practice of blood transfusion with a continuous source of unforeseeable threats with the emergence and re-emergence of blood-borne pathogens. Pathogen reduction (PR) is a proactive strategy to mitigate the risk of transfusion-transmitted infections. PR technologies for the treatment of single plasma units and platelet concentrates are commercially available and have been successfully implemented in more than 2 dozen countries worldwide.

    Red blood cell transfusion policy: a critical literature review.
    Blood Transfus 2017 Jul;15(4):307-317
    Italian National Blood Centre, National Institute of Health, Rome, Italy.
    The issue of the most appropriate red blood cell transfusion policy has been addressed by a number of randomised controlled trials, conducted over the last decades, comparing the effects on patients' outcome of restrictive blood transfusion strategies (transfusing when the haemoglobin concentration is less than 7 g/dL to 8 g/dL) vs more liberal ones (transfusing when the haemoglobin concentration is less than 9 g/dL to 10 g/dL) in a variety of clinical settings. In parallel, various systematic reviews and meta-analyses have tried to perform pooled analyses of the data from these randomised controlled trials and their results have been utilised by scientific societies to provide recommendations and guidelines on red blood cell transfusion thresholds. All these aspects will be critically discussed in this narrative review. Read More

    Red blood cells ageing markers: a multi-parametric analysis.
    Blood Transfus 2017 May;15(3):239-248
    Blood Products Research Laboratory, Interregional Blood Transfusion SRC, Epalinges, Switzerland.
    Background: Red blood cells collected in citrate-phosphate-dextrose can be stored for up to 42 days at 4 °C in saline-adenine-glucose-mannitol additive solution. During this controlled, but nevertheless artificial, ex vivo ageing, red blood cells accumulate lesions that can be reversible or irreversible upon transfusion. The aim of the present study is to follow several parameters reflecting cell metabolism, antioxidant defences, morphology and membrane dynamics during storage. Read More

    Acetylcholinesterase provides new insights into red blood cell ageing in vivo and in vitro.
    Blood Transfus 2017 May;15(3):232-238
    Department of Biochemistry, Radboud Institute for Molecular Life Sciences, Radboud University Medical Centre, Nijmegen, The Netherlands.
    Background: During its 120 days sojourn in the circulation, the red blood cell (RBC) remodels its membrane. Acetylcholinesterase (AChE) is a glycosylphosphatidylinositol (GPI)-linked enzyme that may serve as a marker for membrane processes occurring this ageing-associated remodelling process.

    Materials And Methods: Expression and enzymatic activity of AChE were determined on RBCs of various ages, as obtained by separation based on volume and density (ageing in vivo), and on RBCs of various times of storage in blood bank conditions (ageing in vitro), as well as on RBC-derived vesicles.

    Red blood cell storage time and transfusion: current practice, concerns and future perspectives.
    Blood Transfus 2017 May;15(3):222-231
    Department of Hematology, "Instituto de Investigación Sanitaria San Carlos" (IdISSC), "Hospital Clínico San Carlos", Madrid, Spain.
    Red blood cells (RBCs) units are the most requested transfusion product worldwide. Indications for transfusion include symptomatic anaemia, acute sickle cell crisis, and acute blood loss of more than 30% of the blood volume, with the aim of restoring tissue oxygen delivery. However, stored RBCs from donors are not a qualitative equal product, and, in many ways, this is a matter of concern in the transfusion practice. Read More

    The potential adverse effects of haemolysis.
    Blood Transfus 2017 May;15(3):218-221
    Department of Anaesthesia and Critical Care, "Fondazione IRCCS Istituto Nazionale dei Tumori", Milan, Italy.
    Haemolysis occurs in many haematologic and non-haematologic diseases. Transfusion of packed red blood cells (pRBCs) can result in intravascular haemolysis, in which the RBCs are destroyed within the circulation, and extravascular haemolysis, in which RBCs are phagocytosed in the monocyte-macrophage system. This happens especially after RBCs have been stored under refrigerated conditions for long periods. Read More

    Blood donor deferral policies across Europe and characteristics of men who have sex with men screened for human immunodeficiency virus in blood establishments: data from the European Men-who-have-sex-with-men Internet Survey (EMIS).
    Blood Transfus 2017 Mar 23:1-10. Epub 2017 Mar 23.
    Division for HIV/AIDS, STI and Blood-borne Infections, Department of Infectious Disease Epidemiology, Robert Koch Institute, Berlin, Germany.
    Background: The predominant mode of transmission of human immunodeficiency virus (HIV) in Europe is male-to-male transmission. Men who have sex with men (MSM) are deferred from donating blood in many countries, but nevertheless do donate blood. Based on data from 34 countries, we estimated the proportion of MSM screened for HIV in the context of a blood donation and identified individual factors associated with this HIV screening in order to propose possible public health interventions.

    Blood Transfus 2017 Apr 13:1-11. Epub 2017 Apr 13.
    Italian National Blood Centre, National Institute of Health, Rome, Italy.
    Background: Public cord blood banking is currently managed in Italy by a network of 19 regional cord blood banks coordinated by the National Blood Centre and the National Transplant Centre. A cost analysis was carried out within the Italian network to determine the relationship between cost of cord blood collection and banking and size of the bank inventory, which ranged from 106 to 9,341 units on December 31(st), 2012.

    Materials And Methods: The 19 banks were invited to report costs incurred in 2012 related to cord blood unit collection, transportation, biological validation, characterisation, manipulation, cryopreservation, storage, data management, and general costs. Read More

    Prevention of red cell storage lesion: a comparison of five different additive solutions.
    Blood Transfus 2017 Sep 10;15(5):456-462. Epub 2017 Apr 10.
    Sanquin Blood Bank, Department Product and Process Development, Academic Medical Centre, University of Amsterdam, Amsterdam, The Netherlands.
    Background: In Europe, red cell concentrates (RCC) are usually stored in SAGM (saline-adenine-glucose-mannitol). During storage, in vitro red cell quality declines, including lowered energy status and increased cell lysis. Recently, several additive solutions (ASs), designed to diminish the decline in in vitro quality during storage, have been developed. Read More

    Purinergic control of red blood cell metabolism: novel strategies to improve red cell storage quality.
    Blood Transfus 2017 Apr 12:1-8. Epub 2017 Apr 12.
    Department of Biochemistry and Molecular Biology, The University of Texas Health Science Center at Houston, Houston, TX, United States of America.
    Transfusion of stored blood is regarded as one of the great advances in modern medicine. However, during storage in the blood bank, red blood cells (RBCs) undergo a series of biochemical and biomechanical changes that affect cell morphology and physiology and potentially impair transfusion safety and efficacy. Despite reassuring evidence from clinical trials, it is universally accepted that the storage lesion(s) results in the altered physiology of long-stored RBCs and helps explain the rapid clearance of up to one-fourth of long-stored RBCs from the recipient's bloodstream at 24 hours after administration.

    Department of Internal Medicine, Division of Haematology, University Hospital Centre Zagreb, Zagreb, Croatia.
    Background: Acute and delayed haemolysis, alloimmunisation and pure red cell aplasia (PRCA) are potential complications after ABO incompatible haematopoietic stem cell transplantation (HSCT). The aims of this study were to investigate acute and delayed red blood cell (RBC) antibody-associated complications, including haemolysis, PRCA and alloimmunisation in major and bidirectional ABO incompatible HSCT.

    Materials And Methods: We retrospectively examined the transplant courses of 36 recipients of bone marrow or peripheral blood stem cells from ABO incompatible donors and evaluated the current practice of performing plasmapheresis in patients with higher isoagglutinin titres. Read More

    Mild-to-moderate foeto-maternal haemorrhage in the third trimester and at term of pregnancy: quantitative determination and clinical-diagnostic evaluation.
    Blood Transfus 2017 Apr 19:1-5. Epub 2017 Apr 19.
    Obstetric and Gynaecology Department, "IRCCS Policlinico S. Matteo", Pavia, Italy.
    Background: Foeto-maternal haemorrhage (FMH), a gestational event that occurs before or during delivery, consists of a loss of foetal blood into the maternal circulation. FMH occurs more frequently during the third trimester or labour both in normal and complicated pregnancies. In the case of alloimmunisation, the maternal immunological response and the severity of the resulting foetal or neonatal disease depend on the amount of foetal blood that passes into the maternal circulation.

    Towards pathogen inactivation of red blood cells and whole blood targeting viral DNA/RNA: design, technologies, and future prospects for developing countries.
    Blood Transfus 2017 Apr 13:1-11. Epub 2017 Apr 13.
    International PhD Program of Biomedical Engineering, College of Biomedical Engineering, Taipei Medical University, Taiwan.
    Over 110 million units of blood are collected yearly. The need for blood products is greater in developing countries, but so is the risk of contracting a transfusion-transmitted infection. Without efficient donor screening/viral testing and validated pathogen inactivation technology, the risk of transfusion-transmitted infections correlates with the infection rate of the donor population.

    Temperature-dependent haemolytic propensity of CPDA-1 stored red blood cells vs whole blood - Red cell fragility as donor signature on blood units.
    Blood Transfus 2017 Sep 10;15(5):447-455. Epub 2017 Apr 10.
    Laboratory of Haematology and Transfusion Medicine, Department of Medical Laboratories, Technological and Educational Institute of Athens, Athens, Greece.
    Background: To preserve cellular integrity and avoid bacterial growth, storage and transfer of blood and blood products follow strict guidelines in terms of temperature control. We evaluated the impact of ineligible warming of whole blood donations on the quality of blood components.

    Materials And Methods: One-hundred and twenty units of whole blood (WB) from eligible blood donors were collected in CPDA-1 and stored at 4±2 °C. Read More

    Strategies to identify candidates for D variant genotyping.
    Blood Transfus 2017 Apr 5:1-9. Epub 2017 Apr 5.
    Department of Pathology and Laboratory Medicine, Lewis Katz School of Medicine at Temple University, Philadelphia, PA, United States of America.
    Background: RhD variants have altered D epitopes and/or decreased antigen copies per red cell. Individuals carrying these variants may test antigen negative, weakly positive, or positive by serology, and may or may not be at risk of alloimmunisation after exposure. There have been recommendations to perform RHD genotyping of patients, pregnant women and females of childbearing potential with serological weak D phenotype, to guide prophylactic use of Rh immune globulin (RhIG), and better conserve D-negative blood products.

    Blood Transfus 2017 Apr 5:1-8. Epub 2017 Apr 5.
    Department of Intensive Care Medicine, Academic Medical Centre, Amsterdam, the Netherlands.
    Background: Disciplines involved in diagnosing transfusion-related acute lung injury (TRALI) report according to a "one-hit" theory. However, studies showed that patients with an underlying condition are at increased risk of the development of TRALI. We investigated whether accumulating evidence on the "two-hit" theory has changed the practice of reporting TRALI. Read More

    Effects of potassium adsorption filters on the removal of ammonia from blood products.
    Blood Transfus 2017 Mar 1:1-5. Epub 2017 Mar 1.
    Department of Transfusion Medicine, Tokyo Metropolitan Bokutoh Hospital, Tokyo, Japan.
    Background: Although ammonia in plasma does not usually pass through the blood-brain barrier (BBB), in cases of traumatic brain injury it may do so, acting as a neurotoxin on the brain. Excess intake of ammonia should be restricted in conditions involving BBB breakdown, such as traumatic brain injury. Washing is a method to remove ammonia from blood products, but fresh-frozen plasma and albumin products cannot be washed. Read More
