    Reversal of apixaban induced alterations in haemostasis by different coagulation factor concentrates in patients after hip or knee replacement surgery.
    Blood Transfus 2018 May 11:1-6. Epub 2018 May 11.
    Department of Anaesthesiology and Operative Intensive Care Medicine (CVK), Charité-Universitätsmedizin Berlin, Campus Virchow-Klinikum, Germany.
    Background: Apixaban is a direct oral anticoagulant (DOAC) with a specific inhibition of activated factor X (FXa). In case of bleeding or need of urgent surgery a direct antidote is not yet available. Off-label application of non-specific haemostatic agents, such as prothrombin complex concentrate (PCC) and recombinant FVIIa (rFVIIa), has been reported to reverse the effects of apixaban in in vitro and animal studies.

    A nationwide retrospective study on prevalence of hepatitis E virus infection in Italian blood donors.
    Blood Transfus 2018 May 4:1-9. Epub 2018 May 4.
    Italian National Blood Centre, National Institute of Health, Rome, Italy.
    Background: In Europe, hepatitis E virus (HEV) infection is mainly a food-borne zoonosis, but it can also be transmitted by blood transfusion. It is usually a mild and self-limited infection. However, immunocompromised persons, who are also those more likely to undergo blood transfusions, may develop chronic hepatitis and often cirrhosis. Read More

    Haemolysis index for the screening of intravascular haemolysis: a novel diagnostic opportunity?
    Blood Transfus 2018 May 8:1-5. Epub 2018 May 8.
    Department of Haematology and Transfusion Medicine, "Carlo Poma" Hospital, Mantua, Italy.
    The diagnostic approach to patients with intravascular haemolysis remains challenging, since no first-line laboratory test seems to be entirely suitable for the screening of this condition. Recent evidence shows that an enhanced cell-free haemoglobin (fHb) concentration in serum or plasma is a reliable marker of red blood cell injury, and may also predict clinical outcomes in patients with different forms of haemolytic anaemias. However, the routine use of the haemiglobincyanide assay, the current reference method for measuring fHb, seems unsuitable for a timely diagnosis of intravascular haemolysis, for many safety and practical reasons.

    Red blood cell salvage analysis from clotted blood.
    Blood Transfus 2018 Apr 4:1-5. Epub 2018 Apr 4.
    Department of Anesthesiology, Magee Womens Hospital of the University of Pittsburgh Medical Center, Pittsburgh, PA, United States of America.
    Background: Blood clots discovered within body cavities intra-operatively are often manually broken up and placed in an autotransfusion device to recover autologous blood cells. This study evaluated the efficiency at which these red blood cells can be recovered from clot and to determine if these cells would be free of fibrin and clumping which might pose a risk of micro-emboli.

    Materials And Methods: Whole blood was aliquoted into 25 mL volume samples. Read More

    High resolution melting for F9 gene mutation analysis in patients with haemophilia B.
    Blood Transfus 2018 Feb 28:1-12. Epub 2018 Feb 28.
    Transfusion Service, Haemophilia Centre and Haematology, Castelfranco Veneto Hospital, Castelfranco Veneto, Italy.
    Background: Since 2001, we have used conformation sensitive gel electrophoresis (CSGE) as our first choice for F9 gene mutation screening, leading to the identification of about 300 mutations causing haemophilia B (HB). To circumvent the disadvantages of CSGE, we recently evaluated high-resolution melting analysis (HRM), which represents the next-generation mutation scanning technology.

    Materials And Methods: In order to explore and validate HRM as a new screening method, we analysed 26 HB patients with previous CSGE-detected mutations, 22 patients with CSGE-undetectable mutations and 13 HB patients who had not been previously investigated. Read More

    Non-factor replacement therapy for haemophilia: a current update.

    Scientific Direction, Fondazione IRCCS Ca' Granda-Ospedale Maggiore Policlinico and University of Milan, Milan, Italy.
    One of the most challenging issues facing us in the treatment of haemophilia is the development of alloantibodies against infused factor VIII (FVIII) or factor IX (FIX). Inhibitors render factor replacement therapy ineffective, exposing patients to an unacceptably high risk of morbidity and mortality. Besides the well-known bypassing agents (i. Read More

    SMIM1 polymorphisms in a donor population from southeast Brazil and their correlation with VEL expression.
    Blood Transfus 2018 Jan 11:1-6. Epub 2018 Jan 11.
    INCTs, Unicamp Blood Centre, Campinas, Brazil.
    Background: Vel is a high frequency blood group antigen and its alloantibody is involved in haemolytic transfusion reactions. After elucidation of the molecular basis of the Vel-negative phenotype defined by a 17-base pair deletion in SMIM1, genotyping has been the technique of choice to identify the Vel-negative phenotype, and molecular investigations have contributed to explain Vel expression variability. The present study was aimed at screening for Vel negative blood donors and characterising the genetic changes found in Brazilian donors with altered Vel expression. Read More

    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

    Influence of red blood cell-derived microparticles upon vasoregulation.
    Blood Transfus 2017 Oct 15;15(6):522-534. 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 2018 Feb 30;16(2):200-208. 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
