PURPOSE OF STUDY: The declaration of the recipients adverse reactions (RAR) is one of the field haemovigilance activities. It provides an evaluation of transfusion side effects and thus prevents their appearance. The aim of this study is to analyze, over 14 years, the RAR supports reported in Rabat Ibn Sina hospital. PATIENTS AND METHODS: All of the RAR supports sending to the blood transfusion service were analyzed. The data collected from these supports are: clinical characteristics of the patient, type of incident observed and type of labile blood products (LBP) transfused...

OBJECTIVES: Delayed adverse reactions to blood donation occur after the donor left donation site. Their intrinsic gravity and possible complications can be increased by the fact the donor is alone. This can also increase bad memories, leading to a donation giving up. Blood transfusion centre is only aware in case of donor feedback, hence an event underrating. We choose to compare our data upon delayed adverse donor reactions with those we could find in past studies. METHODS: A first data level comes from French haemovigilance data while serious adverse reactions declaration is mandatory...

Blood cells generate heterogeneous populations of vesicles that are delivered, as small-specialized packages of highly active cell fragments in blood circulation, having almost similar functional activities, as the mother cells. These so called extracellular vesicles are the essential part of an energy-dependent natural apoptotic process; hence their beneficial and harmful biological functions cannot be ignored. Evidence is accumulating, that cellular derived vesicles, originate from all viable cells including: megakaryocytes, platelets, red blood cells, white blood cells and endothelial cells, the highest in proportions from platelets...

We report a case of unusually large fetomaternal haemorrhage in a RhD- patient; of symptomatic non-sustained haemolysis of fetal red cells in the maternal circulation with infusion of intravenous high-dose RhD immunoglobulin; and of a failure to prevent RhD alloimmunisation. The haemolytic reaction is not previously reported in this patient group and we suggest would be limited to patients where the number of fetal red cells in the circulation is high. We advocate caution in treatment and spaced dosing of RhD immunoglobulin where the required dose is high, and refer readers to the WinRhoSDF™ RhD immunoglobulin product information for their updated dosing recommendations...

BACKGROUND: As transfusion in the elderly patients has increased over the last decades, and with the aim of improving blood policy, post-transfusion red blood cell alloimmunisation, a delayed serological transfusion reaction, was investigated in patients 80 years old or over. MATERIAL AND METHODS: For every adverse reaction to a transfusion, a report is sent to the French haemovigilance database. All cases of red blood cell alloimmunisation reported in the haemovigilance database were collected, and an analysis was performed on those cases in transfused patients 80 years old or over...

OBJECTIVES: To discover if any adverse clinical effects have been reported to the UK haemovigilance scheme, Serious Hazards of Transfusion (SHOT) relating to delays in set up of transfusion or extended transfusion time for red cell units. BACKGROUND: Current guidance for duration of transfusion is based on outdated studies that do not reflect current UK Blood Service practices. Recent evidence suggests that the '30-min rule' could be extended without adverse effects...

BACKGROUND: With the implementation of NAT in countries around the world, there is a growing pressure on the transfusion services in India to adopt NAT testing. India has about 2545 licensed Blood Centres. The Transfusion Services in India are fragmented, poorly regulated and the quality standards are poorly implemented. Blood Centres are still dependent on replacement/family donors and in most places laboratory testing for Transfusion transmitted infections is not quality assured, laboratory equipment are not calibrated and maintained, and validation of results is not carried out...

Platelet concentrates account for near 10% of all labile blood components but are responsible for more than 25% of the reported adverse events. Besides factors related to patients themselves, who may be particularly at risk of side effects because of their underlying illness, there are aspects of platelet collection and storage that predispose to adverse events. Platelets for transfusion are strongly activated by collection through disposal equipment, which can stress the cells, and by preservation at 22 °C with rotation or rocking, which likewise leads to platelet activation, perhaps more so than storage at 4 °C...

Blood cells and tissues generate heterogeneous populations of cell-derived vesicles, ranging from approximately 50 nm to 1 µm in diameter. Under normal physiological conditions and as an essential part of an energy-dependent natural process, microparticles (MPs) are continuously shed into the circulation from membranes of all viable cells such as megakaryocytes, platelets, red blood cells, white blood cells and endothelial cells. MP shedding can also be triggered by pathological activation of inflammatory processes and activation of coagulation or complement systems, or even by shear stress in the circulation...

BACKGROUND: To assess the impact of safety measures, we compared reporting rates of transfusion-related reactions before and after the implementation of six measures in 1999, 2004, 2006, 2008 and 2009. METHODS: Reporting rates of transfusion-transmitted bacterial infection (TTBI), viral infection (TTVI) and immune-mediated transfusion-related acute lung injury (TRALI) were calculated on the basis of confirmed annual reports and distributed blood components. RESULTS: The introduction of HCV NAT testing caused a significant reduction of HCV reporting rate from 1:0...

Standard definitions of donor reactions allow each blood establishment to monitor donor adverse events and compare with other organizations to develop best practices. The ISBT Haemovigilance Working Party leads a multi-organizational effort to update the 2008 ISBT standard for surveillance of complications related to blood donation. Revised definitions have been developed and endorsed by the ISBT, AABB, International Haemovigilance Network (IHN) and other international organizations.

AIM: Using both patient-focused and donor-focused perspectives, to review the current EU blood directives, in order to derive proposals, in principle, for what should evolve during the revision process of these directives. METHODS: Review of the EU blood directives in the light of scientific literature, related reports from the Directorate General Health and Consumers (DG SANTÉ), and from the Council of Europe (CoE). RESULTS: The analyses led us to present the main following proposals: developing voluntary unpaid donations: the directives should consider taking into consideration ethically acceptable forms of compensation consistent with altruistic donation (including plasma donations for fractionation); current expertise: more extensive utilization of the expertise of blood establishments and their consultants should be considered; donor selection: an evidence-based approach for basing donor deferral criteria on sound scientific evidence should be promoted; donor reactions: measures to prevent donor reactions and to make donations safer for the donors should also be included; quality control: The quality control requirements should relate to the Council of Europe Blood Guide specifications: these should become minimum standards (as is the case with monographs of the European Pharmacopeia), facilitating regular update of blood component lists and related specifications and compliance with the specifications; haemovigilance: because of reporting difficulties (e...

For many years, nurses have performed the tasks related to blood transfusion monitoring and the associated quality-control documentation. There have been multiple job titles given to healthcare providers in this field: haemovigilance officer, transfusion practitioner, transfusion nurse, patient blood management (PBM) nurse, blood conservation nurse and blood management nurse. These titles share some overlap in tasks. In this article, the authors discuss Australian and US experiences of the historical transfusion nurse role, and the newer title of PBM nurse...

New Zealand Blood Service Haemovigilance uses International Society of Blood Transfusion/International Haemovigilance Network definitions to categorize transfusion reactions (TR). Transfusion-associated dyspnoea (TAD) is a category for TR with respiratory features (TRRF) that do not fit definitive entities. TRRF, including TAD, are clinically significant. TR classified as TAD were reviewed. We found that many TAD may have been transfusion-associated circulatory overload. Better information in TR reports and refining TR diagnostic criteria may result in less misclassification of TRRF...

The acute blood transfusion reactions are responsible for causing most serious adverse events. Awareness about various clinical features of acute and delayed transfusion reactions with an ability to assess the serious reactions on time can lead to a better prognosis. Evidence-based medicine has changed today's scenario of clinical practice to decrease adverse transfusion reactions. New evidence-based algorithms of transfusion and improved haemovigilance lead to avoidance of unnecessary transfusions perioperatively...
