Platelet enhancement of bacterial growth during room temperature storage: mitigation through refrigeration.

Transfusion 2019 Apr;59(S2):1479-1489

U.S. Army Institute of Surgical Research, Coagulation and Blood Research Task Area, Texas.

Introduction: Due to high risk of septic transfusion reactions arising from bacterial contamination, US Food and Drug Administration regulations currently limit platelet storage to 5 days at room temperature (RT). However, blood culturing methods can take up to 7 days to detect bacteria, allowing transfusion of potentially contaminated units. Thus, cold storage (CS) may be a viable means of extending shelf life and improving safety. Read More

Transfusion of pathogen-reduced platelet components without leukoreduction.

Transfusion 2019 Mar 28. Epub 2019 Mar 28.

Queen Mary Hospital and University of Hong Kong, Pok Fu Lam, Hong Kong.

Background: Leukoreduction (LR) of platelet concentrate (PC) has evolved as the standard to mitigate risks of alloimmunization, clinical refractoriness, acute transfusion reactions (ATRs), and cytomegalovirus infection, but does not prevent transfusion-associated graft-versus-host disease (TA-GVHD). Amotosalen-ultraviolet A pathogen reduction (A-PR) of PC reduces risk of transfusion-transmitted infection and TA-GVHD. In vitro data indicate that A-PR effectively inactivates WBCs and infectious pathogens. Read More

Post-Transfusion Purpura Mimicking Idiopathic Thrombocytopenic Purpura: A Case Report.

Lab Med 2019 Mar 27. Epub 2019 Mar 27.

Department of Medicine, Wilmot Cancer Institute, University of Rochester Medical Center, Rochester, NY.

The main clinical distinction between post-transfusion purpura (PTP) and idiopathic thrombocytopenic purpura (ITP) is the sudden development of severe thrombocytopenia in the days after transfusion. Herein, we report the case of a 53-year-old Caucasian woman who developed multiple myeloma (MM) after peripheral blood-stem-cell transplant (PBSCT), along with severe thrombocytopenia (with a nadir of 1 × 109/L); she also experienced severe adverse events after each platelet transfusion, including the first one. These reactions were absent with any other transfused blood products. Read More

Delayed hemolytic transfusion reaction in the French hemovigilance system.

Transfus Clin Biol 2019 Mar 9. Epub 2019 Mar 9.

Agence nationale de sécurité du médicament et des produits de santé (ANSM), 93285 Saint-Denis cedex, France.

In France, reporting of adverse events related, or likely to be related, to transfusion is mandatory. Since its creation in 1993, the French hemovigilance system has contributed to a better recognition of unappreciated risks like delayed hemolytic transfusion reactions (DHTR) in sickle-cell disease (SCD) patients. Long under-reported or misclassified, reports of this serious complication of transfusion have improved, particularly through the dissemination of information within the hemovigilance network.

Molecular Detection of Glycophorins A and B Variant Phenotypes and their Clinical Relevance.

Transfus Med Rev 2019 Feb 23. Epub 2019 Feb 23.

School of Dental Sciences, Universiti Sains Malaysia, Kubang Kerian, Kelantan, Malaysia. Electronic address:

Crossover or conversion between the homologous regions of glycophorin A (GYPA) and glycophorin B (GYPB) gives rise to several different hybrid glycophorin genes encoding a number of different glycophorin variant phenotypes which bear low prevalence antigens in the MNS blood group system. GP.Mur is the main glycophorin variant phenotype which causes hemolytic transfusion reaction (HTR) and hemolytic disease of the fetus and newborn (HDFN) in East and Southeast Asians. Read More

Hypersensitivity transfusion reactions to platelet concentrate: a retrospective analysis of the French hemovigilance network.

Transfusion 2019 Mar 25. Epub 2019 Mar 25.

French National Agency for Medicines and Health Products Safety (ANSM), Saint Denis, France.

Background: Among labile blood products, platelet concentrates (PCs) are the leading cause of hypersensitivity transfusion reactions (HTRs). These reactions often lead to interruption of PC transfusion and can result in a prolonged transfusion process leading to significant morbidity and use of premedication and close monitoring for patients with a history of allergic transfusion reactions. The French hemovigilance database is one of the largest standardized databases providing information on HTRs following administration of labile blood products. Read More

SMIM1 at a glance; discovery, genetic basis, recent progress and perspectives.

Parasite Epidemiol Control 2019 May 6;5:e00101. Epub 2019 Mar 6.

West Africa Centre for Cell Biology of Infectious Pathogens, University of Ghana, Accra, Ghana.

Recent elucidation of the genetic basis of the Vel blood group system has offered the field of blood transfusion medicine an additional consideration in determining the causes of hemolytic reactions after a patient is transfused. The identification of the SMIM1 gene to be responsible for the Vel blood group allows molecular based tools to be developed to further dissect the function of this antigen. Genetic signatures such as the homozygous 17 bp deletion and the heterozygous 17 bp deletion in combination with other single nucleotide polymorphisms (SNPs) and insertion sequences regulate the expression level of the gene.

Post-transfusion purpura in a woman with acute myeloid leukemia.

Neth J Med 2019 Feb;77(2):81-83

Departments of 1nternal Medicine, Amphia Hospital, Breda, the Netherlands.

Post-transfusion purpura (PTP) is a rare, but severe transfusion reaction in which both donor and autologous platelets are sequestered due to immunization against HPA-1a antigens in HPA-1a negative recipients (HPA: human platelet antigens). We describe a patient who developed PTP during induction therapy for acute myeloid leukaemia. The pitfalls, delays in diagnosing and therapy options of this serious transfusion reaction are discussed. Read More

Haemadsorption improves intraoperative haemodynamics and metabolic changes during aortic surgery with hypothermic circulatory arrest†.

Eur J Cardiothorac Surg 2019 Mar 19. Epub 2019 Mar 19.

Department of Cardiac Surgery, University Hospital, LMU Munich, Munich, Germany.

Objectives: Aortic surgery involving hypothermic circulatory arrest (HCA) results in a systemic inflammatory response that may negatively influence outcome. An extracorporeal haemadsorption (HA) device (CytoSorb®) that removes inflammatory triggers may improve haemodynamic and metabolic reactions due to excessive inflammation and, ultimately, outcome.

Methods: As a single-centre experience, the data of 336 patients who had undergone aortic surgery with HCA between 2013 and 2017 were retrospectively analysed. Read More
