    Full Text Available Context: Extensive bleeding associated with liver transplantation is a major challenge faced by transplant surgeons, worldwide. Aims: To evaluate the blood component consumption and determine preoperative factors that predict the same in living donor liver transplantation (LDLT. Settings and Design: This prospective study was performed for a 1 year period, from March 2010 to February 2011. Materials and Methods: Intra- and postoperative utilization of blood components in 152 patients undergoing LDLT was evaluated and preoperative patient parameters like age, gender, height, weight, disease etiology, hemoglobin (Hb, hematocrit (Hct, platelet count (Plt, total leukocyte count (TLC, activated partial thromboplastin time (aPTT, international normalized ratio (INR, serum bilirubin (T. bilirubin, total proteins (T. proteins, albumin to globulin ratio (A/G ratio, serum creatinine (S. creatinine, blood urea (B. urea, and serum electrolytes were assessed to determine their predictive values. Univariate and stepwise discriminant analysis identified those factors, which could predict the consumption of each blood component. Results: The average utilization of packed red cells (PRCs, cryoprecipitates (cryo, apheresis platelets, and fresh frozen plasma was 8.48 units, 2.19 units, 0.93 units, and 2,025 ml, respectively. Disease etiology and blood component consumption were significantly correlated. Separate prediction models which could predict consumption of each blood component in intra and postoperative phase of LDLT were derived from among the preoperative Hb, Hct, model for end-stage liver disease (MELD score, body surface area (BSA, Plt, T. proteins, S. creatinine, B. urea, INR, and serum sodium and chloride. Conclusions: Preoperative variables can effectively predict the blood component requirements during liver transplantation, thereby allowing blood transfusion services in being better prepared for surgical procedure.

    Full Text Available Transfusion medicine has been constantly evolving through the years with improved technologies that enhance the capability of identifying existing and newer emerging transfusion transmissible infections (TTI. In spite of the efforts made by blood banks the risk of TTI remains. This article deals with the various steps involved in ensuring blood safety, i.e. donor selection, role of screening donated blood for known and emerging infections, issues and assessment of threat posed by the risk, methodologies employed for testing and possible suggestions to improve transfusion services. While the threat of TTI remains, with a concerted effort of private and government organisations, and co-operation from the diagnostic companies, it is possible to raise the levels of blood safety. A surveillance system is also essential to identify any new agents that might pose a threat in a geographic area and to include them too in the screening process.

    The risks associated with transfusion with blood components have been greatly reduced due to the implementation of innovative strategies for donor selection and testing, as well as safety measures such as universal prestorage leukocyte reduction. However, a variety of residual or unsolved risks, such as severe acute reaction of transfusion-related acute lung injury, transfusion-associated circulatory overload and transfusion-transmitted infections, remain. Patients with hematological disorders are at high risk, since they receive therapeutic interventions frequently requiring transfusion. Thereby, balancing risk and benefit for patients, hematologists should prescribe blood components through evidence-based decision-making, minimize unnecessary transfusions and then conduct safe and error-free transfusion with a standard procedure involving the transfusion process at the bedside.

    1995-01-01

    This paper describes the organizational structure and the economic impact of blood donation and transfusion in Greece and discusses some alternative aspects of its financing and its costing policy. The cost of blood transfusion is rising in Greece and amounts to nearly 15 billion drachmas per year due to the constant increase in demand and consequently, the price of each unit of blood. The production and distribution of blood on national scale involves meeting the demand for 500.000 units. Blood is mostly given by the friends and relatives of patients (55%) and by voluntary blood donation (30%). Approximately 50% of the blood produced is used in surgery, 20% for cases of beta-thalassaemia, 10% for emergencies and 20% for internal medicine cases. The blood transfusion system is totally funded by the state budget and the value to users is free of charge. The way in which blood is collected and processed differs from one geographical area to another and the unit cost depends on the size of the department concerned, ranging from 60-150 $. The need to control costs and restrain expenditure, in conjunction with guarantees of sufficiency and quality, makes it essential that measures should be taken to introduce economies of scale and encourage competition among blood providers, for increased production, components preparation and rational usage of blood. The introduction of a costing policy becomes necessary in this effort to achieve cost-containment techniques. PMID:8581182

    Although there are lots of studies about the risk for the hepatitis B virus infection such as the residual risk for donated blood, there is no research on the risk of HBV infection, from the viewpoint of recipients in Korea. Using the data about HBsAg status of donated blood in 2008 and 2009, the distribution of blood components from the claim data of health insurance in 2009, the distribution of HBsAg and HBsAb of recipients, and some assumptions, we quantified the number of recipients in Korea that might be expected to receive HBV-contaminated blood components, as a proxy index for HBV infection by transfusion in 2009. Of the 376,211 recipients, the number who might be expected to receive blood components with HBV in 2009 was 23.2 (95 % CI 13.6, 36.8) in the basic model, 43.2 (95 % CI 25.4, 68.7) in extended model I, 55.2 (95 % CI 32.5, 87.7) in extended model II and 101.6 (95 % CI 59.8, 161.4) in extended model III. The number of HBV-positive samples per 100,000 transfused units was 0.6 in the basic model (95 % CI 0.3, 0.9), 1.1 in extended model I (95 % CI 0.6, 1.8), 1.4 in extended model II (95 % CI 0.8, 2.2), and 2.6 in extended model III (95 % CI 1.5, 4.1). This study showed that a few recipients might receive HBV-contaminated blood component by transfusion. These results could be used as a scientific evidence for health policy on HBV transfusion infection. PMID:27429524

    As any therapeutic means, blood transfusion requires regular evaluation, particularly for its indications, effectiveness and risks. The availability of randomized clinical trials, the evolution of the quality of blood components, and the economic constraints shared by all countries, all lead to rethink both transfusion therapy as a whole and the organization of the transfusion chain from donor to recipient. The main tools available to improve transfusion and the transfusion chain management are the following: programs of patient blood management (PBM) to optimize the use of blood products with a patient centred approach, blood supply management tools to improve the effectiveness and efficiency of the transfusion chain, donor management tools to adapt donor collections to the patients' needs in compliance with safety requirements for patients and donors, and coordination of these activities. A better understanding of these tools and their implementation will certainly be major challenges for transfusion medicine in the near future. Integrating these evolutions in regulations through the revision of the European Directives on blood and blood components (the review process is expected to be launched in 2015) should enroll them in the long term, for the benefit of patients, donors and all other stakeholders involved in the transfusion chain.

    Full Text Available Blood transfusion is an essential component of emergency obstetric care and appropriate blood transfusion significantly reduces maternal mortality. Obstetric haemorrhage, especially postpartum haemorrhage, remains one of the major causes of massive haemorrhage and a prime cause of maternal mortality. Blood loss and assessment of its correct requirement are difficult in pregnancy due to physiological changes and comorbid conditions. Many guidelines have been used to assess the requirement and transfusion of blood and its components. Infrastructural, economic, social and religious constraints in blood banking and donation are key issues to formulate practice guidelines. Available current guidelines for transfusion are mostly from the developed world; however, they can be used by developing countries keeping available resources in perspective.

    Full Text Available Paediatric patients undergoing surgical procedures commonly require some volume of blood or blood component replacement in the perioperative period. Paediatric patients undergoing major surgery associated with substantial blood loss should be evaluated pre-operatively. Pre-operative correction of anaemia may be done considering the age, plasma volume status, clinical status and comorbidities. Maximum allowable blood loss (MABL for surgery must be calculated, and appropriate quantity of blood and blood components should be arranged. Intraoperative monitoring of blood loss should be done, and volume of transfusion should be calculated in a protocol based manner considering the volemia and the trigger threshold for transfusion for the patient and the MABL. Early haemostasis should be achieved by judicious administration of red blood cells, blood components and pharmacological agents.

    The transfusion of allogeneic red blood cells (RBCs) and other blood components is ingrained in modern medical practice. The rationale for administering transfusions is based on key assumptions that efficacy is established and risks are acceptable and minimized. Despite the cliché that, "the blood supply is safer than ever," data about risks and lack of efficacy of RBC transfusions in several clinical settings have steadily accumulated. Frequentist statisticians and clinicians demand evidence from randomized clinical trials (RCTs); however, causation for the recognized serious hazards of allogeneic transfusion has never been established in this manner. On the other hand, the preponderance of evidence implicating RBC transfusions in adverse clinical outcomes related to immunomodulation and the storage lesion comes from observational studies, and a broad and critical analysis to evaluate causation is overdue. It is suggested in several circumstances that this cannot wait for the design, execution, and conduct of rigorous RCTs. We begin by examining the nature and definition of causation with relevant examples from transfusion medicine. Deductive deterministic methods may be applied to most of the well-accepted and understood serious hazards of transfusion, with modified Koch's postulates being fulfilled in most circumstances. On the other hand, when several possible interacting risk factors exist and RBC transfusions are associated with adverse clinical outcomes, establishing causation requires inferential probabilistic methodology. In the latter circumstances, the case for RBC transfusions being causal for adverse clinical outcomes can be strengthened by applying modified Bradford Hill criteria to the plethora of existing observational studies. This being the case, a greater precautionary approach to RBC transfusion is necessary and equipoise that justifying RCTs may become problematic. PMID:21345639

    Pretransplant blood transfusion remains a controversial subject and its history can summarize the last 40 years of transplantation. Until 1971, transfusions were widely used in patients awaiting transplantation, especially due to the anemia induced by the chronic renal dysfunction. Then, a noxious effect of preformed anti-HLA antibodies on renal grafts survival was reported and pretransplant transfusions were stopped. Between 1972 and 1977, improvement of renal graft survival in patients who received pretransplant transfusions was noted. Therefore, from 1978 on, a systematic policy of pretransplant transfusions was adopted by almost all centres of transplantation. During the eighties, it was again abandoned for several reasons: absence of graft survival improvement in patients treated by cyclosporine, HLA immunization leading to an increased incidence of acute graft rejection, risk of viral diseases transmission and human recombinant erythropoietin development. The lack of improvement in graft survival for ten years has been leading the transplant community to look for antigen-specific immunosuppressive strategies to achieve transplantation tolerance. Donor-specific transfusion may have clinical benefits, as long-term grafts survival improvement, through modulation of the recipient's cellular immune system and has been recently reconsidered, especially before living donor transplantation. The immunological mechanisms inducing a tolerance-gaining effect of transfusions are still misunderstood, but the recent discovery of immunomodulatory effects of the apoptotic cells present in cellular products could enlighten our comprehension of pretransplant transfusions benefits and could help to develop specific tolerance induction strategies in solid organ transplantation.

  10. Blood transfusion practices in cardiac anaesthesia

    Hanumantha Rao Mangu

    2014-01-01

    Full Text Available The primary reasons for blood transfusion in cardiac surgery are to correct anaemia and to improve tissue oxygen delivery. However, there is a considerable debate regarding the actual transfusion trigger at which the benefits of transfusion overweight the risk. The association between extreme haemodilution, transfusion and adverse outcome after cardio pulmonary bypass (CPB is not clear and the current available literature is not sufficient to provide a strong recommendation regarding the safe haematocrit range during CPB. There is no quality evidence to support use of fresh red blood cell except during massive transfusion or exchange transfusion in neonate. Overall concern regarding the safety of allogeneic blood transfusion resulted in the search for autologous blood transfusion and perioperative blood salvage. The aim of this review is to provide cardiac surgery specific clinically useful guidelines pertaining to transfusion triggers, optimal haemodilution during CPB, autologous blood transfusion and role of perioperative blood salvage based on available evidence.

  11. From mad cows to sensible blood transfusion: the risk of prion transmission by labile blood components in the United Kingdom and in France.

    2009-04-01

    Transfusion transmission of the prion, the agent of variant Creutzfeldt-Jakob disease (vCJD), is now established. Subjects infected through food may transmit the disease through blood donations. The two nations most affected to date by this threat are the United Kingdom (UK) and France. The first transfusion cases have been observed in the UK over the past 5 years. In France, a few individuals who developed vCJD had a history of blood donation, leading to a risk of transmission to recipients, some of whom could be incubating the disease. In the absence of a large-scale screening test, it is impossible to establish the prevalence of infection in the blood donor population and transfused patients. This lack of a test also prevents specific screening of blood donations. Thus, prevention of transfusion transmission essentially relies at present on deferral of "at-risk" individuals. Because prions are present in both white blood cells and plasma, leukoreduction is probably insufficient to totally eliminate the transfusion risk. In the absence of a screening test for blood donations, recently developed prion-specific filters could be a solution. Furthermore, while the dietary spread of vCJD seems efficiently controlled, uncertainty remains as to the extent of the spread of prions through blood transfusion and other secondary routes.

    Autologous blood transfusion (ABT) has been gradually attracting more attention due to the increasingly prominent problem of blood transfusion safety and blood shortage in recent years. With the rapid development of blood conservation techniques, blood component separation technology, blood transfusion medicine and a constant increase in clinical needs, ABT technology has been expanded and innovated to a large degree. In this study, the development of preoperative autologous blood donation (PABD), acute normovolemic hemodilution (ANH), intraoperative and postoperative autotransfusion, and other new technologies and theories are reviewed and existing questions are analyzed. Challenges and applications are also discussed in order to provide reference for peers. PMID:27533770

    Human blood has been transfused for about 60-70 years. Over this time, the practice of blood transfusion has changed dramatically. One major change is the separation of blood into its various components. As a result, the patient can receive only the blood component in which he is deficient. In this way, the risk of side effects—particularly hepatitis—is lessened. This article briefly reviews the various blood products, the indications for their use, and some associated risks.

    Full Text Available Blood loss and blood transfusion have been inherently associated with liver transplantation. Bleeding has been attributed to the various factors which are associated with chronic liver dysfunction. Various surgical and anaesthetic strategies have been developed over the years to reduce bleeding and also to optimise the usage of various blood and blood products perioperatively. The present day success of liver transplantation can be attributed to these issues where transfusion practices have changed. Although several centres are successfully performing liver transplantations in large numbers, there is still a large variability in the usage of blood and blood products perioperatively among the institutions and even among different anaesthesiologists from the same institution. The present article deals with the various factors confounding this concept of blood transfusion practices and the various strategies adopted to reduce the transfusion requirements in the perioperative period.

    The level of safety attained in blood transfusion now makes this a discipline better managed care activities. This was achieved both by scientific advances and policy decisions regulating and supervising the activity, as well as by the quality system, which we recall that affects the entire organizational structure, responsibilities, procedures, processes and resources in place to achieve quality management. So, an effective quality system provides a framework within which activities are established, performed in a quality-focused way and continuously monitored to improve outcomes. This system quality has to irrigate all the actors of the transfusion, just as much the establishments of blood transfusion than the health establishments. PMID:25578550

    Of the 21 million blood components transfused in the United States during 2011, approximately 1 in 414 resulted in complication [1]. Two complications in particular, transfusion-related acute lung injury (TRALI) and transfusion-associated circulatory overload (TACO), are especially concerning. These two alone accounted for 62% of reported transfusion-related fatalities in 2013 [2]. We have previously developed a set of machine learning base models for predicting the likelihood of these adverse reactions, with a goal towards better informing the clinician prior to a transfusion decision. Here we describe recent work incorporating ensemble learning approaches to predicting TACO/TRALI. In particular we describe combining base models via majority voting, stacking of model sets with varying diversity, as well as a resampling/boosting combination algorithm called RUSBoost. We find that while the performance of many models is very good, the ensemble models do not yield significantly better performance in terms of AUC. PMID:26737958

    Full Text Available Background: Blood Transfusion is recognized as one of the eight essential component of comprehensive emergency obstetric care which has been shown to reduce the maternal mortality.1,2 In developing country like India, efforts should be done to make blood and transfusion services well maintained and quickly available to reduce maternal morbidity from haemorrhage and thus decrease the incidence of maternal mortality. Aims and objectives: (1 To study clinical status of the patients at time of admission. (2 To study the role of antenatal visits in all patients required blood transfusion. (3 To study the effect of blood components on the patients' health. (4 To screen out the patients of high risk pregnancy and treat them safely. (5 To study causes of maternal mortality. Methods: Retrospective study of requirement of blood transfusion in antenatal and postnatal patients who came in labour room during last 3 month period at tertiary care Centre, Ahmedabad. Results: during the whole study out of 2200 patients 440 patients required blood transfusion among which 70% required due to obstetric hemorrhage and 30% due to severe anemia (less than 7 gm/dl. Major associated complications in the transfused patients were anemia (34% and PPH (36%. 4 patients expired among them 2 were due to development of DIC and septicemia, 1 due to severe anemia and 1 due to severe PPH. Conclusions: Ensuring a safe supply of blood and blood products and the appropriate and rational clinical use of blood. Strategies made to maximize the haemoglobin (Hb level at the time of delivery as well as to minimize blood loss. Active management of the third stage of labour is required to prevent avoidable morbidities, such as PPH, Retained product of conception, and vaginal lacerations.

As an example, fresh whole blood in large-volume hemorrhage may be superior to whole blood reconstituted from multiple components. Multicomponent apheresis can overcome logistical difficulties in matching patient needs with fresh component availability and can deliver the benefits of fresh whole blood. Because of the different transfusion needs of patients in emerging economies and the vulnerability of these blood systems to emerging infections, fresh whole blood and multicomponent apheresis can better meet patient needs when compared with transplants of the "manufacturing paradigm". We propose that patient blood management, along with panels of repeat, paid, accredited apheresis and fresh whole-blood donors can be used in emerging economies to support decentralized blood services. This alternative transfusion–medicine paradigm could eventually also be adopted by established economies to focus transfusion medicine on local patient needs and to alleviate the problem of the aging volunteer donor base.Keywords: indications, emerging countries, patient blood management

    Full Text Available Background: Sultanate of Oman is geographically situated in south-west of Asia, having common borders on western side by the land with United Arab Emirates, Saudi Arabia and Yemen and with the Arabian Sea and the Gulf of Oman in the east and the north respectively. The country enjoys one of the best health care facilities including blood transfusion services in the region. Study design: Information was collected through informal personal interviews, digging out the past records, and the report presentations at various forums. Results: A modest start by providing blood units through import, the country is now self-reliant on procuring blood units from voluntary non-remunerate blood donors within the sultanate. A steady growth of blood banks is witnessed in every aspect of blood banking including blood collection, blood processing and supply. Various modalities are adapted in promoting voluntary blood donation programme. Conclusion: Sultanate of Oman has created one of the best blood transfusion services in the region in providing safe blood for transfusion through voluntary donation, a use of blood components and irradiating blood products.

    Despite being prohibited by the World Anti-Doping Agency, blood doping through erythropoietin injection or blood transfusion is frequently used by athletes to increase oxygen delivery to muscles and enhance performance. In contrast with allogeneic blood transfusion and erythropoietic stimulants, there is presently no direct method of detection for autologous blood transfusion (ABT) doping. Blood reinfusion is currently monitored with individual follow-up of hematological variables via the athlete biological passport, which requires further improvement. Microdosage is undetectable, and suspicious profiles in athletes are often attributed to exposure to altitude, heat stress, or illness. Additional indirect biomarkers may increase the sensitivity and specificity of the longitudinal approach. The emergence of "-omics" strategies provides new opportunities to discover biomarkers for the indirect detection of ABT. With the development of direct quantitative methods, transcriptomics based on microRNA or messenger RNA expression is a promising approach. Because blood donation and blood reinfusion alter iron metabolism, quantification of proteins involved in metal metabolism, such as hepcidin, may be applied in an "ironomics" strategy to improve the detection of ABT. As red blood cell (RBC) storage triggers changes in membrane proteins, proteomic methods have the potential to identify the presence of stored RBCs in blood. Alternatively, urine matrix can be used for the quantification of the plasticizer di(2-ethyhexyl)phthalate and its metabolites that originate from blood storage bags, suggesting recent blood transfusion, and have an important degree of sensitivity and specificity. This review proposes that various indirect biomarkers should be applied in combination with mathematical approaches for longitudinal monitoring aimed at improving ABT detection. PMID:27260108

    Full Text Available Transfusions of blood and blood products are commonly used in medicine, but being biological materials they carry a risk of transmitting infections--viral, bacterial, parasitic, as well as prions. Laboratory tests used for screening of donated blood for viral infections at present cannot detect all infectious units. Criteria for selection of blood donors therefore must be very strict, while methods of inactivation of viruses and laboratory assays for detection of their presence must be improved. Indications for blood transfusion should be restricted.

  15. Blood transfusion safety: a new philosophy.

    Science.gov (United States)

    Franklin, I M

    2012-12-01

    Blood transfusion safety has had a chequered history, and there are current and future challenges. Internationally, there is no clear consensus for many aspects of the provision of safe blood, although pan-national legislation does provide a baseline framework in the European Union. Costs are rising, and new safety measures can appear expensive, especially when tested against some other medical interventions, such as cancer treatment and vaccination programmes. In this article, it is proposed that a comprehensive approach is taken to the issue of blood transfusion safety that considers all aspects of the process rather than considering only new measures. The need for an agreed level of safety for specified and unknown risks is also suggested. The importance of providing care and support for those inadvertently injured as a result of transfusion problems is also made. Given that the current blood safety decision process often uses a utilitarian principle for decision making--through the calculation of Quality Adjusted Life Years--an alternative philosophy is proposed. A social contract for blood safety, based on the principles of 'justice as fairness' developed by John Rawls, is recommended as a means of providing an agreed level of safety, containing costs and providing support for any adverse outcomes.

    In this study significantly prolonged canine renal allograft survival has been demonstrated after transfusion of 100 ml of third-party whole blood given peroperatively. Peroperative transfusions of third-party leukocyte-free blood or pure lymphocyte cell suspensions did not influence graft survival. Furthermore, no improvement in graft survival has been found after a peroperative transfusion of irradiated whole blood (2500 rad). These data suggest that delayed graft rejection after blood transfusions can only be expected after the administration of whole blood. The role of competent lymphocytes in whole blood is questionable, since a transfusion or irradiated whole blood in combination with nonirradiated lymphocytes did not lead to prolonged graft survival. Immunosuppression of the recipient directly after transfusion seems to be essential to induce the beneficial effect of blood transfusions. This has been demonstrated for a transfusion of whole blood 14 days before transplantation. A single transfusion of 100 ml of whole blood 14 days before transplantation could effectively prolong graft survival if immunosuppression with azathioprine and prednisone was started on the day of transfusion. No improvement in graft survival has been found with such a transfusion if preoperative immunosuppression has been omitted.

    Early resuscitation of bleeding trauma patients with multiple blood products improves outcome, yet transfusion initiation is not standardized. Shock index (heart rate/systolic blood pressure) and trauma bay uncrossmatched red blood cell (RBC) transfusion were evaluated for association with multiple transfusions, defined as 6 or more RBCs during the first 6 hrs of hospital presentation. A prehospital shock index of 1 was significantly associated with multiple transfusions (p = .02). Subjects receiving uncrossmatched RBCs required more RBCs during the first 6 hrs (10.3 units, p < .01). Consideration of these simple variables may help trauma nurses anticipate the potentially bleeding patient. PMID:26953537

    Full Text Available Background: The goal of hemovigilance is to increase the safety and quality of blood transfusion. Identification of the adverse reactions will help in taking appropriate steps to reduce their incidence and make blood transfusion process as safe as possible. Aims : To determine the frequency and type of transfusion reactions (TRs occurring in patients, reported to the blood bank at our institute. Materials and Methods : A retrospective review of all TRs reported to the blood bank at the All India Institute of Medical Sciences, between December 2007 and April 2012 was done. All the TRs were evaluated in the blood bank and classified using standard definitions. Results: During the study period a total of 380,658 bloods and blood components were issued by our blood bank. Out of the total 196 adverse reactions reported under the hemovigilance system, the most common type of reaction observed was allergic 55.1% (n = 108, followed by febrile non-hemolytic transfusion reaction (FNHTR 35.7% (n = 70. Other less frequently observed reactions were Anaphylactoid reactions 5.1% (n = 10, Acute non-immune HTRs 2.6% (n = 5, Circulatory overload 0.5% (n = 1, Transfusion related acute lung injury 0.5% (n = 1, Delayed HTRs 0.5% (n = 1. Not a single case of bacterial contamination was observed. Conclusion: The frequency of TRs in our patients was found to be 0.05% (196 out of 380,658. This can be an underestimation of the true incidence because of under reporting. It should be the responsibility of the blood transfusion consultant to create awareness amongst their clinical counterpart about safe transfusion practices so that proper hemovigilance system can be achieved to provide better patient care.

    Full Text Available The Safety of the Blood Supply in any country is of utmost importance to safeguard patients from serious adverse events of blood transfusion. Implementation of a Quality System in the Blood Transfusion Service, with support of Government and Ministry of Health is a key element to guarantee safe blood. The IPA TAIB 2009 project - Strengthening of the Blood Safety System executed in 2013/14 provided the means to start implementing a Quality System in the Institute for Transfusion Medicine of the Republic of Macedonia. This project aimed to ultimately bring the Blood Transfusion Service to European Union standards, allowing the exchange of blood components and all other types of collaboration with other European Union countries in future. The project put the basis for unification of blood transfusion standards and operating procedures in the whole country as well as set up essential education of blood transfusion personnel.

    Quality management is an ongoing development resulting in consistency products and services and ever increasing customer satisfaction. The ultimum is Total Quality Management. Quality systems and quality management in transfusion medicine have gained considerable attention since the outbreak of the AIDS epidemic. Where product orientation has long been applied through quality control, Good Manufacturing Practice (GMP) principles were introduced, shifting the developments in the direction of process orientation. Globally, and particularly in the more industrialised world people and system orientation has come along with the introduction of the ISO9001 concept. Harmonisation and a degree of uniformity are needed to implement a universally applicable Quality System and related Quality Management. Where the American Association of Blood Banks (AABB) is the professional organisation with the most extensive experience in quality systems in blood transfusion, the European Union and the Council of Europe now are in the process to design a quality system and management applicable to a larger variety of countries, based on a hybrid of current GMP and ISO9001 principles. The International Federation of Red Cross and Red Crescent Societies has developed a more universally to implement Quality Manual, with a pilot project in Honduras. It is recommendable to harmonise the various designs and bring the approaches under one common denominator. PMID:10938970

    Full Text Available Perioperative fluid, electrolyte and blood transfusion therapy for infants and children can be confusing due the numerous opinions, formulas and clinical applications, which can result in a picture that is not practical and is often misleading. Perioperatively, crystalloids, colloids and blood components are required to meet the ongoing losses and for maintaining cardiovascular stability to sustain adequate tissue perfusion. Recently controversies have been raised regarding historically used formulas and practices of glucose containing hypotonic maintenance crystalloid solutions for perioperative fluid therapy in children. Paediatric intraoperative transfusion therapy, particularly the approach to massive blood transfusion (blood loss ≥ one blood volume can be quite complex because of the unique relationship between the patient′s blood volume and the volume of the individual blood product transfused. A meticulous fluid, electrolyte and blood transfusion management is required in paediatric patients perioperatively because of an extremely limited margin for error. This article reviews the basic concepts in perioperative fluid and blood transfusion therapy for paediatric patients, along with recent recommendations. For this review, Pubmed, Ovid MEDLINE, HINARI and Google scholar were searched without date restrictions. Search terms included the following in various combinations: Perioperative, fluid therapy, paediatrics, blood transfusion, electrolyte disturbances and guidelines. Only articles with English translation were used.

    Full Text Available Anemia is common in critically ill patients. As a consequence packed red blood cell (PRBC transfusions are frequent in the critically ill. Over the past two decades a growing body of literature has emerged, linking PRBC transfusion to infections, immunosuppression, organ dysfunction, and a higher mortality rate. However, despite growing evidence that risk of PRBC transfusion outweighs its benefit, significant numbers of critically ill patients still receive PRBC transfusion during their intensive care unit (ICU stay. In this paper, we summarize the current literature concerning the impact of anemia on outcomes in critically ill patients and the potential complications of PRBC transfusions.

    Despite considerable advances in the safety of blood components, transfusion associated bacterial infection (TABI) remains an unresolved problem. As yet there are no perfect preventative, screening and/or detection methodologies for eliminating contaminated units. Until a practical, rapid, cost-effective and logistically acceptable test becomes available, we should be satisfied with the choice of various limited solutions that at least partially improve the bacterial safety of blood components. It is also necessary to establish standardised guidelines and agreed upon systematic procedures for the recognition and reporting of the laboratory and clinical evaluation of adverse reactions in recipients of contaminated blood components.

    2014-01-01

    Full Text Available Introduction. Autologous blood transfusion is a set of procedures done in order to collect a patient’s blood and reinfuse it during or after a surgical intervention. The aim is to meet the patient’s need for blood products without allogeneic transfusion. By observing the hemoglobin and hematocrit values during blood donation in the pre-operative and post-operative period and by counting transfused blood units, the aim of this article was to detect whether there was any difference between the patients receiving autologous blood and those receiving only allogeneic blood. Material and Methods. This prospective study was performed at the General Hospital ”Đorđe Joanović” Zrenjanin from October 24th, 2011 to January 24th, 2013. The study included 60 patients who were divided into the experimental group of 30 patients who had been transfused autologous blood and the control group of 30 patients who had been transfused only allogeneic blood. Results. The average values of hemoglobin and hematocrit in the first and the second donation were 148.9 g/l and 44.2%, and 138.7 g/l and 40.8%, respectively. Oral iron preparation was given to 12 patients for two weeks before the first donation. The level of hemoglobin and hematocrit in both groups of patients had approximately the same values in the pre-operative and post-operative period. In the post-operative period, 2.53 units were transfused per patient in the experimental group and 3.73 units were transfused per patient in the control group. Conclusion. Administration of pre-operatively donated autogenous blood reduces the number of transfused deplasmatised erythrocytes units in comparison to the number of units transfused to the patients receiving only allogeneic blood products. The pre-operative use of oral iron preparations increases hemoglobin values significantly.

    Blood platelets prepared for transfusion gradually lose hemostatic function during storage. Platelet function can be investigated using a variety of (indirect) in vitro experiments, but none of these is as comprehensive as microfluidic flow chambers. In this protocol, the reconstitution of thrombocytopenic fresh blood with stored blood bank platelets is used to simulate platelet transfusion. Next, the reconstituted sample is perfused in microfluidic flow chambers which mimic hemostasis on exposed subendothelial matrix proteins. Effects of blood donation, transport, component separation, storage and pathogen inactivation can be measured in paired experimental designs. This allows reliable comparison of the impact every manipulation in blood component preparation has on hemostasis. Our results demonstrate the impact of temperature cycling, shear rates, platelet concentration and storage duration on platelet function. In conclusion, this protocol analyzes the function of blood bank platelets and this ultimately aids in optimization of the processing chain including phlebotomy, transport, component preparation, storage and transfusion.

  1. History of blood transfusion in sub-saharan Africa.

    Schneider, William H

    2013-01-01

    The adequacy and safety of blood transfusion in sub-Saharan Africa is the subject of much concern, yet there have been very few studies of its history. An overview of that record finds that transfusions were first reported in Africa (sub-Saharan and excluding South Africa) in the early 1920s, and organized transfusion practices were established before the Second World War. Blood transfusion grew rapidly after 1945, along with the construction of new hospitals and expanded health services in Africa. Significant differences existed between colonial powers in the organization of transfusion services, but these converged after independence as their use continued to grow and decentralized and hospital-based practices were adopted. It was only after the oil crisis in the mid-1970s that health spending declined and the collection, testing, and transfusion of blood began to level off. Thus, when the AIDS crisis hit transfusion services, they were already struggling to meet the needs of patients. At this time, foreign assistance as well as the World Health Organization and the League of Red Cross Societies helped respond to both the immediate problem of testing blood, and for some countries, support existed for the broader reorganization of transfusion. Overall, the history shows that transfusion was adopted widely and quickly, limited mainly by the availability of knowledgeable doctors and hospital facilities. There was less resistance than expected by Africans to receive transfusions, and the record shows a remarkable flexibility in obtaining blood. The dangers of disease transmission were recognized from an early date but were balanced against the potential lifesaving benefits of transfusion. PMID:22981696

    Full Text Available "nCurrently, in Iran blood transfusion is an integral part of the national health system and blood donation is voluntary and non­remu­nerated and blood and its components may not be a source of profit. In 1974 and following establishment of Iranian Blood Transfusion Organization (IBTO all blood transfusion activities from donor recruitment to production of blood com­po­nents and delivery of blood and blood products were centralized. The activities of IBTO are followed the laws and regu­la­tions of Ministry of Health and criteria of Iran National Regulatory Authority. In order to meet the country's demand in 2007 IBTO collected about 1.7 millions units of blood from the population of 70 millions. In 1979 coincided with the Is­lamic revolution the number of  blood units collected throughout the country were 124,000 units or 3.4 unit per 1000 popu­la­tion whereas after about 30 years this increased to about 25 unit per 1000 population. With improving the pool of vol­un­tary donors, IBTO has been successful in excluding "family replacement" donation since 2007 and reached to 100% volun­tary and nonremunerated blood donation. Currently more than 92% of blood donors in Iran are male and contribution of fe­male in blood donation is less than 8%. Although all donated blood in Iran screened for HBsAg since 1974, screening of blood units for HIV and HCV started since 1989 and 1996, respectively. The frequency of HBV infection in blood do­nors showed a significant decline from 1.79% in 1998 to 0.4% in 2007. The overall frequency of HCV and HIV infection are 0.13% and 0.004% respectively.

    Major obstetric hemorrhage remains the leading cause of maternal morbidity and mortality worldwide. Even though blood transfusion may be a life-saving procedure, an inappropriate usage of blood products in obstetric emergencies especially in cases of massive bleeding is associated with increased morbidity and risk of death. Thorough knowledge of the etiology, pathophysiology, and optimal therapeutic options of major obstetric hemorrhage may help to avoid lethal outcomes. There are evidence-based data about some risks related with transfusion of blood components: acute or delayed hemolytic, febrile, allergic reactions, transfusion-related acute lung injury, negative immunomodulative effect, transmission of infectious diseases, dissemination of cancer. This is why the indications for allogeneic blood transfusion are restricted, and new safer methods are being discovered to decrease the requirement for it. Red cell alloimmunization may develop in pregnancy; therefore, all pregnant women should pass screening for irregular antibodies. Antierythrocytic irregular antibodies may occur due to previous pregnancies or allogeneic red blood cell transfusions, and it is important for blood cross-matching in the future. Under certain circumstances, such as complicated maternal history, severe coagulation abnormalities, severe anemia, the preparation of cross-matched blood is necessary. There is evidence of very significant variation in the use of blood products (red cells, platelets, fresh frozen plasma, or cryoprecipitate) among clinicians in various medical institutions, and sometimes indications for transfusion are not correctly motivated. The transfusion of each single blood product must be performed only in case of evaluation of expected effect. The need for blood products and for their combination is necessary to estimate for each patient individually in case of obstetric emergencies either. Indications for transfusion of blood components in obstetrics are presented in

    Viral safety remains a major concern in transfusion of blood products. Over years, the control measures applied to blood products were made more and more sophisticated; however, the number of infectious agents, and notably of viruses, that can be transmitted by transfusion is increasing continuously. The aim of this review paper is to actualize that published in the same journal by the same authors in 2011 with more details on some of actual vs virtual viral threats that were identified recently in the field of blood transfusion. The main subjects that are covered successively concern the transmission via transfusion of hepatitis E virus, the frequency of transfusion transmitted arboviruses, transfusion at the time of the Ebola epidemics in West Africa, the debated role of Marseillevirus (giant viruses infecting amoebae and suspected to infect human blood latently), and, finally, the recent report of the identification in blood donors of a new member of the Flaviviridae family. The addition of these new viral risks to those already identified-partially controlled or not-pleads for the urgent need to move forward to considering inactivation of infectious agents in blood products.

    Blood transfusion is required in a number of emergency settings and the French military health service (FMHS) has issued specific guidelines for the treatment of war casualties. These guidelines take into account European standards and laws, NATO standards, and also public sentiment regarding transfusion. These guidelines reflect a determination to control the process and to avoid the improvisation frequently associated with wartime transfusion. The evolution in warfare (terrorism and bombing more frequent than gunshot) and the wide use of body armor have deeply changed the clinical presentation of war injuries. These now involve the extremities in 80% of cases, with extensive tissue damage and heavy blood loss. The FMHS recommends that war casualties with hemorrhagic shock be brought quickly to a medical treatment facility (MTF) after first-line treatment applied through buddy aid or by medics. In the MTF, before an early Medevac, a damage control surgery will be performed, with resuscitation using freeze-dried plasma, red blood cells and fresh whole blood. The French military blood bank is responsible for blood product supply, training and medical advice regarding transfusion therapy during wartime, as well as hemovigilance. All transfusion therapy practices are periodically assessed but research on whole blood pathogen reduction is being conducted in order to reduce the residual infectious risk associated with this product.

    Full Text Available Gaetano ChiricoNeonatology and Neonatal Intensive Care Unit, Children Hospital, Spedali Civili, Brescia, ItalyAbstract: Preterm neonates, especially very low birth weight infants, remain a category of patients with high transfusion needs; about 90% of those with <1,000 g birth weight may be transfused several times during their hospital stay. However, neonatal red blood cells (RBC transfusion is not without risks. In addition to well-known adverse events, several severe side effects have been observed unique to preterm infants, such as transfusion-related acute gut injury, intraventricular hemorrhage, and increased mortality risk. It is therefore important to reduce the frequency of RBC transfusion in critically ill neonates, by delayed clamping or milking the umbilical cord, using residual cord blood for initial laboratory investigations, reducing phlebotomy losses, determining transfusion guidelines, and ensuring the most appropriate nutrition, with the optimal supplementation of iron, folic acid, and vitamins. Ideally, RBC transfusion should be tailored to the individual requirements of the single infant. However, many controversies still remain, and the decision on whether to transfuse or not is often made on an empirical basis. Recently, a few clinical trials have been performed with the aim to compare the risk/benefit ratio of restrictive versus liberal transfusion criteria. No significant differences in short-term outcomes were observed, suggesting that the restrictive criteria may reduce the need for transfusion and the related side effects. Neurodevelopmental long-term outcome seemed more favorable in the liberal group at first evaluation, especially for boys, and significantly better in the restrictive group at a later clinical investigation. Magnetic resonance imaging scans, performed at an average age of 12 years, showed that intracranial volume was substantially smaller in the liberal group compared with controls. When sex effects

    This cross-sectional, observational study was carried out among the blood receiving patients conducted in the Department of Transfusion Medicine, Bangabandhu Sheikh Mujib Medical University from April 2008 to August 2009, over 126 purposively selected, to evaluate the extent of awareness about hazards of blood transfusion among the blood recipient. In this study 74.1% of male and 73.3% of female respondents had correct knowledge of blood transfusion (p>0.05). In literate group 85(91.4%) had knowledge about blood donation and transfusion compared to 8(8.6%) in illiterate group with significant statistical difference (p=0.001). Different misconception and lack of awareness about safe blood transfusion is present among people receiving blood and blood products. Illiterate persons have significant less level of knowledge about safe blood transfusion. So the number of educational programs on blood-donation should be expanded and transmitted to encourage possible receivers to take blood from nonprofessional volunteer donor and to carry out relevant screening tests before receiving blood products. Furthermore, they should know that all measures besides screening tests are implemented by blood banks to ensure that blood donation is safe for donors and that transfusion of the donated blood is safe for recipients.

Antibodies were found in 103 patients: A 63 patients with single antibodies: 1 16 with antibodies of unknown specificity (3 autoantibodies, 13 alloantibodies; 2 39 with clinically significant antibodies (23 from Rh system (2 anti-C, 2 anti-D, 12 anti-E, 7 anti-c, 4 anti-K, 3 anti-Fya, 7 anti-Jka, 2 anti-S; 3 8 with usually not significant antibodies (6 anti-M, 1 anti-A1, 1 anti- Cw; B 40 patients developed multiple antibodies: 1 all patients had at least one clinically significant antibody from various blood group system (44 Rh, 13 Kell, 7 Kidd, 7 MNSs (S, s; 2 3 patients had usually not significant antibodies (1 Lewis, 2 Lutheran; 3 3 patients occasionally had clinically significant antibody (3 anti- Yta; 4 3 patients had antibodies of unknown specificity (2 autoantibodies, 1alloantibody. Antibodies detected in the majority of patients (65-63.1% had a specificity of Rh and/or the Kell system. Conclusions. The main goal of pre-transfusion blood compatibility testing is to detect clinically significant antibodies. The provision of antigen negative blood units for those patients is a special challenge for blood establishments. Database with a sufficient number of typed blood donors can help to resolve this problem.

    Blood transfusion plays a critical role in the provision of medical care for disasters due to man-made and natural hazards. Although the short-term increase in blood donations following national disasters is well-documented, some aspects of blood transfusion during disasters remain under study. The 2003 earthquake in Bam, Iran resulted in the death of >29,000 people and injured 23,000. In total, 108,985 blood units were donated, but only 21,347 units (23%) actually were distributed to hospitals around the country. Kerman Province, the site of the disaster, received 1,231 (1.3%) of the donated units in the first four days after the disaster. The Bam experience revealed crucial missteps in the development of a post-event strategy for blood product management, and led to the development of a detailed disaster preparedness and response plan that addresses issues of donation, distribution, communication, transportation, and coordination. The current plan requires the Iranian Blood Transfusion Organization to convene a disaster task force immediately as the main coordinator of all disaster preparedness and response activities.

    The overall use of allogeneic blood transfusions in clinical practice remains relatively high and still varies widely among centres and practitioners. Moreover, allogeneic blood transfusions have historically been linked with risks and complications: some of them (e.g. transfusion reactions and transmission of pathogens) have been largely mitigated through advancements in blood banking whereas some others (e.g. immunomodulation and transfusion-related acute lung injury) appear to have more subtle etiologies and are more difficult to tackle. Furthermore, blood transfusions are costly and the supply of blood is limited. Finally, evidence indicates that a great number of the critically ill patients who are being transfused today may not be having tangible benefits from the transfusion. Patient blood management is an evidence-based, multidisciplinary, multimodal, and patient-tailored approach aimed at reducing or eliminating the need for allogeneic transfusion by managing anaemia, perioperative blood conservation, surgical haemostasis, and blood as well as plasma-derivative drug use. From this point of view, the reduction of allogeneic blood usage is not an end in itself but a tool to achieve better patient clinical outcome. This article focuses on the three-pillar matrix of patient blood management where the understanding of basic physiology and pathophysiology is at the core of evidence-based approaches to optimizing erythropoiesis, minimising bleeding and tolerating anemia. Anesthesiologists and critical care physicians clearly have a key role in patient blood management programmes are and should incorporate its principles into clinical practice-based initiatives that improve patient safety and clinical outcomes.

    Autologous blood transfusion (ABT) is an efficient way to increase sport performance. It is also the most challenging doping method to detect. At present, individual follow-up of haematological variables via the athlete biological passport (ABP) is used to detect it. Quantification of a novel hepatic peptide called hepcidin may be a new alternative to detect ABT. In this prospective clinical trial, healthy subjects received a saline injection for the control phase, after which they donated blood that was stored and then transfused 36 days later. The impact of ABT on hepcidin as well as haematological parameters, iron metabolism, and inflammation markers was investigated. Blood transfusion had a particularly marked effect on hepcidin concentrations compared to the other biomarkers, which included haematological variables. Hepcidin concentrations increased significantly: 12 hr and 1 day after blood reinfusion, these concentrations rose by seven- and fourfold, respectively. No significant change was observed in the control phase. Hepcidin quantification is a cost-effective strategy that could be used in an "ironomics" strategy to improve the detection of ABT. Am. J.

  15. Bioethics and religious bodies: refusal of blood transfusions in Germany.

    Science.gov (United States)

    Rajtar, Małgorzata

    2013-12-01

    The refusal of medical treatment is a recurrent topic in bioethical debates and Jehovah's Witnesses often constitute an exemplary case in this regard. The refusal of a potentially life-saving blood transfusion is a controversial choice that challenges the basic medical principle of acting in patients' best interests and often leads physicians to adopt paternalistic attitudes toward patients who refuse transfusion. However, neither existing bioethical nor historical and social sciences scholarship sufficiently addresses experiences of rank-and-file Witnesses in their dealings with the health care system. This article draws on results of a nine-month (2010, 2011-2012) ethnographic research on the relationship between religious, legal, ethical, and emotional issues emerging from the refusal of blood transfusions by Jehovah's Witnesses in Germany (mainly in Berlin). It shows how bioethical challenges are solved in practice by some German physicians and what they perceive to be the main goal of biomedicine: promoting the health or broadly understood well-being of patients. I argue that two different understandings of the concept of autonomy are at work here: autonomy based on reason and autonomy based on choice. The first is privileged by German physicians in line with a Kantian philosophical tradition and constitutional law; the second, paradoxically, is utilized by Jehovah's Witnesses in their version of the Anglo-Saxon Millian approach.

    Full Text Available Background: Adverse transfusion reactions can cause morbidity and death to patients who receive a blood transfusion. Blood transfusion practice in Mulago Hospital, Kampala, Uganda is analyzed to see if and when these practices play a role in the morbidity and mortality of patients. Materials and Methods: An observational study on three wards of Mulago Hospital. Physicians, paramedics, nurses, medical students and nurse students were observed using two questionnaires. For comparison, a limited observational study was performed in the University Medical Centre Groningen (UMCG in Groningen, The Netherlands. Results: In Mulago Hospital guidelines for blood transfusion practice were not easily available. Medical staff members work on individual professional levels. Students perform poorly due to inconsistency in their supervision. Documentation of blood transfusion in patient files is scarce. There is no immediate bedside observation, so transfusion reactions and obstructions in the blood transfusion flow are not observed. Conclusion: The poor blood transfusion practice is likely to play a role in the morbidity and mortality of patients who receive a blood transfusion. There is a need for a blood transfusion policy and current practical guidelines.

  19. Contaminating fibrin in CPD-blood: solubility in plasma and distribution in blood components following separation

    International Nuclear Information System (INIS)

    In order to estimate the solubility of contaminating fibrin in CPD-blood, thrombin induced fibrin polymerzation in CPD-plasma was examined by light scattering and fibrinopeptide A (FPA) determinations. In addition, I-125 fibrin monomer enriched CPD-blood was used to investigate fibrin monomer retention in blood bags and transfusion filters (170 microns) and fibrin distribution in blood components derived from CPD-blood. Initial fibrin polymerization in CPD-blood occurred after conversion of 15 per cent of the fibrinogen to fibrin, implying that substantial amounts of fibrin may be kept solubilized in CPD-blood bags. Only minor amounts of I-125 fibrin monomers were retained in blood bags (2.4 per cent) and in transfusion filters (2.9 per cent) after sham transfusions. After separating I-125-fibrin monomer enriched CPD-blood into its constituent components, the major part of fibrin (75.0 per cent) could be traced in the cryoprecipitate

    AIM To investigate the role of blood transfusion in TT viral infection (TTV).METHODS We retrospectively studied serum samples from 192 transfusion recipients who underwent cardiovascular surgery and blood transfusion between July 1991 and June 1992. All patients had a follow-up every other week for at least 6 months after transfusion. Eighty recipients recipents blood before screening donors for hepatitis C antibody (anti-HCV), and 112 recipients reveiver screened blood.Recipients with alanine aminotransferase level > 2.5 times the upper normal limit were tested for serological markers for viral hepatitis A, B,C, G, Epstein-Barr virus and cytomegalovirus.TTV infection was defined by the positivity for serum TTV DNA using the polymerase chain reaction method. RESULTS Eleven and three patients, who reveiver anti-HCV unscreened and screened blood, respectively, had serum ALT levels >90 IU/L. Five patients (HCV and TTV: 1; HCV,HGV, and TTV: 1; TTV: 2; and CMV and TTV: 1 )were positive for TTV DNA, and four of them had sero-conversion of TTV DNA. CONCLUSION TTV can be transmitted via blood transfusion. Two recipients infected by TTV alone may be associated with the hepatitis.However, whether TTV was the causal agent remains unsettled, and further studies are necessary to define the role of TTV infection in chronic hepatitis.

    Transfusion-transmitted infections including hepatitis Bvirus (HBV) have been a major concern in transfusionmedicine. Implementation of HBV nucleic acid testing(NAT) has revealed occult HBV infection (OBI) in blooddonors. In the mid-1980s, hepatitis B core antibody(HBc) testing was introduced to screen blood donorsin HBV non-endemic countries to prevent transmissionof non-A and non-B hepatitis. That test remains inuse for preventing of potential transmission of HBVfrom hepatitis B surface antigen (HBsAg)-negativeblood donors, even though anti-hepatitis C virus testshave been introduced. Studies of anti-HBc-positivedonors have revealed an HBV DNA positivity rate of0%-15%. As of 2012, 30 countries have implementedHBV NAT. The prevalence of OBI in blood donors wasestimated to be 8.55 per 1 million donations, accordingto a 2008 international survey. OBI is transmissible byblood transfusion. The clinical outcome of occult HBVtransmission primarily depends on recipient immunestatus and the number of HBV DNA copies present in theblood products. The presence of donor anti-HBs reducesthe risk of HBV infection by approximately five-fold. Therisk of HBV transmission may be lower in endemic areasthan in non-endemic areas, because most recipientshave already been exposed to HBV. Blood safety forHBV, including OBI, has substantially improved, but thepossibility for OBI transmission remains.

    Full Text Available Cees Th. Smit Sibinga ID Consulting, Zuidhorn, The NetherlandsTransfusion Medicine is a bridging science, spanning the evidence-based practice at the bedside with the social sciences in the community.     Transfusion Medicine starts at the bedside. Surprisingly, only recently that has become rediscovered with the development of ‘patient blood management’ and ‘patient centered’ approaches to allow the growth of an optimal and rational patient care through supportive hemotherapy – safe and effective, affordable and accessible.1    Where transfusion of blood found its origin in the need of a patient, it has drifted away for a long period of time from the bedside and has been dominated for almost a century by laboratory sciences. At least the first ten editions of the famous and well reputed textbook Mollison’s Blood Transfusion in Clinical Medicine contained only a fraction on the actual bedside practice of transfusion medicine and did not focus at all on patient blood management.2    This journal will focus on all aspects of the transfusion chain that immediately relate to the bedside practice and clinical use of blood and its components, and plasma derivatives as integral elements of a human transplant tissue. That includes legal and regulatory aspects, medical, ethical and cultural aspects, pure science and pathophysiology of disease and the impact of transfusion of blood, as well as aspects of the epidemiology of blood transfusion and clinical indications, and cost-effectiveness. Education through timely and continued transfer of up to date knowledge and the application of knowledge in clinical practice to develop and maintain clinical skills and competence, with the extension of current educational approaches through e-learning and accessible ‘apps’ will be given a prominent place.

Aims: The present study was designed to determine the seroprevalence of TTIs viz., HIV, HCV, and HBV, among the blood donors in Max Super Specialty Hospital, New Delhi, India based on dual testing strategy using high sensitive screening assays such as enhanced chemiluminescence assay and nucleic acid testing (NAT. Materials and Methods: A total of 41207 blood units collected from the donors (both voluntary and replacement donors were screened for the TTI s, viz., anti HIV 1 and 2 antibody, anti HCV antibody, anti HBcore antibody, and HBsAg by enhanced chemiluminescence assay on VITROS ® ECiQ immunodiagnostics system. NAT was performed using Roche Cobas ® TaqScreen MPX assay, which can detect simultaneously HIV 1 (groups M and O, HIV-2, HCV, and HBV on Roche Cobas ® s201 system. Results: The seroprevalence of HIV, HBsAg, anti HBcore antibody, and HCV based on enhanced chemiluminescence assay was found to be 0.25, 0.2, 7.06, and 0.7%, respectively. A total number of 6587 samples from July 2010 to December 2010 were tested on NAT, of which 3 samples were reactive for HBV in NAT; this was missed by enhanced chemiluminescence assay. Conclusions: Based on the seroprevalence study of infectious diseases viz., HIV, HBV, and HCV, we conclude that screening of blood and blood components by dual testing strategy using high sensitivity serological assay like enhanced chemiluminescence technology and NAT helps in detecting the

    Background: Allogeneic blood transfusion-induced immunomodulation (TRIM) and its adverse effect on the prognosis of patients treated surgically for cancer remain complex and controversial. However, the potential risk associated with allogeneic blood transfusion has heightened interest in the use of autologous blood transfusion. In the present study, the serum concentrations of neopterin, interferon-gamma (IFN-γ), T lymphocyte subsets (CD3+, CD4+, CD8+, CD4+/CD8+) and a possible association between these variables were investigated. The purpose was to further evaluate the effect of autologous versus allogeneic blood transfusion on immunological status in patients undergoing surgery for gastric cancer. Methods: Sixty ASA Ⅰ~Ⅱ(American Society of Anesthesiologists) patients undergoing elective radical resection for stomach cancer were randomly allocated to receive either allogeneic blood transfusion (n=30) or autologous blood transfusion (n=30). Serum concentrations of the neopterin, IFN-γ and T lymphocyte subsets in the recipients were measured before induction of anesthesia, after operation, and on the 5th postoperative day. Results: Both two groups, serum neopterin, IFN-γ, percentages of T-cell subsets (CD3+, CD4+), and CD4+/CD8+ ratio had significantly decreased after operation, but decreased more significantly in group H (receiving allogeneic blood transfusion) than those in group A (receiving autologous whole blood transfusion) (P<0.05). On the 5th postoperative day,serum neopterin, IFN-γ, CD3+, CD4+ T-cells, and CD4+/CD8+ ratio returned to the baseline values in group A. In contrast, the above remain decreasing in group H, where there were no significant relations between serum neopterin and IFN-γ. Conclusion:Perioperative surgical trauma and stress have an immunosuppressive impact on gastric cancer patients. Allogeneic blood transfusion exacerbates the impaired immune response. Autologous blood transfusion might be significantly beneficial for

Objectives: The aim of this study was to evaluate the practice of obstetric blood transfusion, the mean decision-transfusion interval, and the outcome in parturients who had blood transfusions. Methods: This was a prospective descriptive study conducted at the Federal Teaching Hospital, Abakaliki, South-East Nigeria, between 1st January, 2012 and 31st December, 2012. Statistical analysis was done using SPSS version 15.0 for Windows. Results: Out of 151 parturients who received blood transfusion, 141/151 (97.4% were knowledgeable about blood transfusion, while only 10/151 (2.6% had no knowledge of it. The hospital was the source of information for 120/151 (80.8% of the participants. Blood transfusion rate was 7.04% of all parturients. The mean decision-transfusion interval was 12.0 ± 4.3 hours. All participants were transfused with either whole blood or sedimented cells. The mean number of blood units transfused was 1.77 ± 0.93 units. The indications for transfusion were: anemia, 109/151 (72.2%; shock, 13/151 (8.6%; postpartum hemorrhage, 23/151 (15.2%; antepartum hemorrhage, 6 (4%.

    Anemia in patients with malignancy is common as a consequence of their disease and treatment. Substantial progress has been made in the management of anemia with red blood cell transfusion in acute conditions, such as bleeding and infection, through the performance of large clinical trials. These trials suggest that transfusion at lower hemoglobin thresholds (restrictive transfusion ∼7-8 g/dL) is safe and in some cases superior to higher transfusion thresholds (liberal transfusion ∼9-10 g/dL). However, additional studies are needed in patients with malignancy to understand best practice in relation to quality of life as well as clinical outcomes. PMID:27112994

  15. Attitude, belief and knowledge about blood donation and transfusion in saudi population

    International Nuclear Information System (INIS)

    Blood donation and transfusion are remarkably safe medical procedures. However, attitudes, beliefs and level of knowledge associated with blood donation and transfusion may affect such procedures. Therefore, the aim of this study was to determine the attitude, belief and knowledge about blood donation and transfusion in Saudi Population. The present study was conducted in the Department of Physiology, College of Medicine, King Saud University Hospitals, Riyadh, Saudi Arabia. A well structured Arabic questionnaire was used to asses the attitude, belief and knowledge regarding blood donation and transfusion. The sample consisted of 335 male (55%) and 274 female (45%); the majority of the sample (65.84%) were non-donors. These non-donors (78.98%) were between the ages of 15-30 years. The 88.5% of the people who participated in the study believed that blood donation was not harmful, 20% of them stated that they would refuse blood transfusion even if they were in need because of the risk of acquiring infectious disease. 84.5% preferred direct donation, (49%) of the sample stated that they would accept blood donation only from relatives, 55.1% believed that blood transfusion was safe. However, 11.6% claimed to have acquired infectious disease after blood transfusion, 58% female in addition to 11.34% male preferred to receive blood from female donor and 69.5% did not know if the blood banks were in need of blood or not and 17.4% believed that all surgical procedures require blood transfusion. Different fears, mistrust in hospital and lack of information may serve as an important issue to be addressed when developing donors recruitment programs or campaigns to clear misconceptions about blood donation. In addition, public should know that numerous screening measures are implemented to ensure that blood donation is safe for the donor and that transfusion of the donated blood is safe for the recipient.

    18 thalassaemic children, aged 3.5 to 13 years comprise our clinical material. In 14 of them, clinically elicited spleen markings, haematocrit, blood platelet count and red cell morphology were studied daily for a whole period between 2 transfusions. In 10 patients considerable changes in spleen size were noticed. According to our clinical observations the spleen size starts decreasing 1 to 3 d after blood transfusion up to the 10th posttransfusion day fluctuating thereafter to reach its maximum size again prior to the next blood transfusion. The decrease of spleen size was followed by an increase of haematocrit and blood platelet count and vice versa. 4 additional children were studied clinically only twice: prior to and 7 to 10 d after blood transfusion. A definite decrease of the spleen size following blood transfusion was observed. Spleen and liver sup(99m)Tc-sulfur colloid uptake was studied in 10 of the above children prior to and 7 to 10 d after blood transfusion. Statistically significant post-transfusion increase of the spleen uptake was demonstrated. Our findings suggest that (a) splenic size is relevant to blood volume sequestered in this organ, (b) splenic radioactive uptake increases with its post-transfusion reduction in size.

    Early detection of hemorrhagic shock is required to facilitate prompt coordination of blood component therapy delivery to the bedside and to expedite performance of lifesaving interventions. Standard physical findings and vital signs are difficult to measure during the acute resuscitation stage, and these measures are often inaccurate until patients deteriorate to a state of decompensated shock. The aim of this study is to examine a severely injured trauma patient population to determine whether a noninvasive SpHb monitor can predict the need for urgent blood transfusion (universal donor or additional urgent blood transfusion) during the first 12 h of trauma patient resuscitation. We hypothesize that trends in continuous SpHb, combined with easily derived patient-specific factors, can identify the immediate need for transfusion in trauma patients. Subjects were enrolled if directly admitted to the trauma center, >17 years of age, and with a shock index (heart rate/systolic blood pressure) >0.62. Upon admission, a Masimo Radical-7 co-oximeter sensor (Masimo Corporation, Irvine, CA) was applied, providing measurement of continuous non-invasive hemoglobin (SpHb) levels. Blood was drawn and hemoglobin concentration analyzed and conventional pulse oximetry photopletysmograph signals were continuously recorded. Demographic information and both prehospital and admission vital signs were collected. The primary outcome was transfusion of at least one unit of packed red blood cells within 24 h of admission. Eight regression models (C1-C8) were evaluated for the prediction of blood use by comparing area under receiver operating curve (AUROC) at different time intervals after admission. 711 subjects had continuous vital signs waveforms available, to include heart rate (HR), SpHb and SpO2 trends. When SpHb was monitored for 15 min, SpHb did not increase AUROC for prediction of transfusion. The highest ROC was recorded for model C8 (age, sex, prehospital shock index, admission

    Full Text Available Blood and blood components are considered drugs because they are used in the treatment of diseases. As with any drug, adverse effects may occur, necessitating careful consideration of therapy. Like any other therapeutic decision, the need for transfusion should be considered on the basis of risks and benefits and alternative treatments available to avoid over- and under-transfusion. This review is focused on the blood transfusion protocol in trauma patients with hemorrhagic shock. Besides, issues related to emergency and massive transfusion have also been elaborated. We conducted a comprehensive MEDLINE search and reviewed the relevant literature, with particular reference to emergency medical care in trauma.

    Full Text Available Background : Children suffering from beta-thalassemia major require repeated blood transfusions which may be associated with dangers like iron overload and contraction of infections such as HIV, HCV, and HBsAg which ultimately curtail their life span. On the other hand, inadequate transfusions lead to severe anemia and general fatigue and debility. Materials and Methods: Data were obtained from 142 beta-thalassemia major patients aged 3 years or more receiving regular blood transfusions at a transfusion centre in Western India from 1 April 2009 to 30 June 2009. The clinical data and laboratory results were subsequently analyzed. Results: Of the 142 patients, 76 (53.5% were undertransfused (mean Hb <10 gm%. 96 (67% of the patients were taking some form of chelation therapy but out of them only 2 (2% were adequately chelated (S. ferritin <1000 ng/ml. 5 (3.5% of the patients were known diabetics on insulin therapy. 103 (72% of the patients were retarded in terms of growth. The prevalence of transfusion-transmitted infections (TTIs such as HCV, HIV, and HBsAg was respectively 45%, 2%, and 2%, with the prevalence of HCV being significantly more than the general population. The HCV prevalence showed positive correlation with the age of the patients and with the total no of blood transfusions received. As many as 15% (6 out of 40 children who were born on or after 2002 were HCV positive despite the blood they received being subjected to screening for HCV. Conclusions: The study suggests the need to step up the transfusions to achieve hemoglobin goal of 10 gm% (as per the moderate transfusion regimen and also to institute urgent and effective chelation measures with the aim of keeping serum ferritin levels below 1000 ng/ml to avoid the systemic effects of iron overload. In addition, strict monitoring of the children for endocrinopathy and other systemic effects of iron overload should be done. Rigid implementation of quality control measures for the

However, certain complications, such as alloimmunization to red blood cells, can create challenges in the management of those patients. Routine phenotyping of blood recipients and the use of phenotype-matched blood units for transfusion have been useful to lower the occurrence of red cell alloantibodies in chronically transfused individuals. Nevertheless, extensive phenotyping is expensive, laborious, and cannot be performed in certain situations. The molecular understanding of blood groups has enabled the design of assays that may be used to better guide matched red blood cell transfusions. This review summarizes key findings related to red cell alloimmunization, the already identified and potential future benefits of blood group genotyping, and how molecular typing is being incorporated in the blood bank's routine to improve clinical and long-term outcomes in chronically transfused patients.

    Background Perioperative bleeding is a predictor of morbidity following liver resection. The transfusion-related score (TRS), which is derived from five variables (cirrhosis, preoperative haemoglobin level, tumour size, vena cava exposure and associated extraliver surgical procedure), has been proposed to predict the likelihood of transfusion in liver resection. Objective The purpose of this observational study was to evaluate the external validity of the TRS. Methods In a retrospective, monocentre, observational cohort study of patients undergoing elective liver resection surgery, data for transfused and non-transfused patients were compared by univariate analysis. The TRS was calculated for each patient. The frequency of transfusion was calculated for each score level. The accuracy of the TRS was evaluated using the area under the receiver operator characteristic curve (AUC). Results A total of 205 patients submitted to liver resection were included. Of these, 48 (23.4%) patients received a blood transfusion. There was no significant difference between transfused and non-transfused patients in age, American Society of Anesthesiologists (ASA) score or cirrhosis. The AUC for the TRS was 0.68 (95% confidence interval 0.59–0.77). Among TRS items, only vena cava exposure and associated surgical procedures were significantly associated with risk for transfusion. Conclusions In the present population, the TRS appeared to serve as a weak predictor of perioperative transfusion. This study confirms that the external validity of the transfusion predictive score should be subject to further investigation before it can be implemented in clinical use. PMID:25516363

There are no evidence-based guidelines for blood transfusions in TSA patients. Materials and Methods: We utilized the Nationwide Inpatient Sample to analyze 51,191 patients undergoing TSA between 1998 and 2011. The purpose was to describe the incidence and identify the preoperative factors that are independently associated with blood transfusion after TSA. In addition, we studied the association of blood transfusions with certain variables such as length of stay (LOS, total charges, and payer status. Results: The blood transfusion rate in our study was 6.1%. There was no difference in the rate of blood transfusions over the study period (P < 0.001. In our logistic regression model, significant associations were found with increased age (odds ratio [OR] =1.03, white race (OR = 1.05, higher Charlson-Deyo score (OR = 1.12, presence of ischemic heart disease (OR = 1.24, blood loss anemia (OR = 1.65, female gender (OR = 1.94, presence of coagulation disorders (OR = 2.25, and presence of deficiency anemia (OR = 3.5. Patients receiving a blood transfusion had higher total charges, a longer hospital LOS, and were more likely to be Medicare payers (P < 0.001. Conclusions: Our study found five clinically significant risk factors for blood transfusions for TSA: female gender, ischemic heart disease, deficiency anemia, coagulation disorder, and blood loss anemia. Patients with these risk factors should be considered higher risk for requiring a blood transfusion after TSA and counseled appropriately.

    Uncontrolled hemorrhage and exsanguination are the leading cause of preventable death, and resuscitative therapy is a critical component for survival. In various combinations, fresh whole blood, blood components, colloids, and crystalloids have all been staples of trauma care. The use of fresh whole blood is a well-established military practice that has saved the lives of thousands of American and coalition military personnel. Civilian use of fresh whole blood is far less established owing to the wide availability of individual blood components. However, this highly tailored blood supply is vulnerable to both natural and man-made disasters. In the event of such disruption, such as a major hurricane, it may be necessary for civilian hospitals to rapidly enact a fresh whole blood program. Therefore, the aim of this article is to review the current use of blood therapy for trauma resuscitation, the US military's approach to fresh whole blood, and how maintaining a civilian capacity for fresh whole blood collection in the event of future man-made and natural disasters is key to promoting survival from trauma.

    Full Text Available The purpose of the present investigation was to examine the impact of blood transfusion on resource utilisation, morbidity and mortality in patients undergoing coronary artery bypass graft (CABG surgery at a major university hospital. The resources we examined are time to extubation, intensive care unit length of stay (ICULOS and postoperative length of stay (PLOS. We further examined the impact of number of units of packed red blood cells (PRBCs transfused during PLOS. This is a retrospective observational study and includes 1746 consecutive male and female patients undergoing primary CABG (on- and off-pump at our institution. Of these, 1067 patients received blood transfusions, while 677 did not. The data regarding the demography, blood transfusion, resource utilisation, morbidity and mortality were collected from the records of patients undergoing CABG over a period of three years. The mean time to extubation following surgery was 8.0 h for the transfused group and 4.3 h for the nontransfused group ( P ≤ 0.001. The mean ICULOS for the transfused group was 1.6 d and 1.2 d for the nontransfused group ( P < 0.001. The PLOS was 7.2 d for the transfused group and 4.3 d for no-transfused cohorts ( P ≤ 0.001. In all patients and in patients with no preoperative morbidity, partial correlation coefficients were used to examine the effects of transfusion on mortality, time to extubation, ICULOS and PLOS. Linear regression model was used to assess the effect of number of PRBC units transfused on PLOS. We noted that PLOS increased with the number of PRBCs units transfused. Transfusion is significantly correlated with the increased time to extubation, ICULOS, PLOS and mortality. The transfused patients had significantly more postoperative complications than their nontransfused counterparts ( P ≤ 0.001. The 30-day hospital mortality was 3.1% for the transfused group with no deaths in the nontransfused group ( P ≤ 0.001. We conclude that the CABG

    Anemia is common in critically ill patients. Although the goal of transfusion of red blood cells is to increase oxygen-carrying capacity, there are contradictory results about whether red blood cell transfusion to treat moderate anemia (e.g., hemoglobin 7-10 g/dL) improves tissue oxygenation or changes outcomes. Whereas increasing levels of anemia eventually lead to a level of critical oxygen delivery, increased cardiac output and oxygen extraction are homeostatic mechanisms the body uses to prevent a state of dysoxia in the setting of diminished oxygen delivery due to anemia. In order for cardiac output to increase in the face of anemia, normovolemia must be maintained. Transfusion of red blood cells increases blood viscosity, which may actually decrease cardiac output (barring a state of hypovolemia prior to transfusion). Studies have generally shown that transfusion of red blood cells fails to increase oxygen uptake unless oxygen uptake/oxygen delivery dependency exists (e.g., severe anemia or strenuous exercise). Recently, near-infrared spectroscopy, which approximates the hemoglobin saturation of venous blood, has been used to investigate whether transfusion of red blood cells increases tissue oxygenation in regional tissue beds (e.g., brain, peripheral skeletal muscle). These studies have generally shown increases in near-infrared spectroscopy derived measurements of tissue oxygenation following transfusion. Studies evaluating the effect of transfusion on the microcirculation have shown that transfusion increases the functional capillary density. This article will review fundamental aspects of oxygen delivery and extraction, and the effects of red blood cell transfusion on tissue oxygenation as well as the microcirculation. PMID:22238040

    Full Text Available Abstract Background In the Confidential Enquiry into Maternal Deaths (CEMD Report, the very high risk of mortality in women who refuse blood transfusions is highlighted. The objectives were to establish current knowledge about, and views of transfusion in our pregnant population and to establish the level of compliance with the set audit standard. Method Questionnaire survey of 228 women, including both high and low risk pregnancies, attending ante-natal clinic between 2–9 May 2000 at the North Staffordshire Maternity Hospital, Stoke on Trent. Results The response rate was 100%. Only 43% were aware of the possible need for blood transfusion in pregnancy. If a blood transfusion was required, 92% stated that they would accept a blood transfusion in pregnancy. Four percent stated that they would not accept a transfusion because of religious reasons and risk of infection and the remaining four percent did not declare a reason. Conclusions This short survey identified that 57% of women were not aware of the possible need for blood transfusion during pregnancy. There is a need for more information to be shared on this subject with all antenatal women. Women who would refuse a transfusion need to be identified at booking and be referred for counselling and a management plan made for pregnancy, labour and delivery.

    2016-01-01

    As any therapeutic means, blood transfusion requires regular evaluation, particularly for its indications, effectiveness and risks. A better awareness of the risks of blood transfusion, the availability of randomized clinical trials, the evolution of the quality of blood components, and the economic constraints shared by all countries, all have led to rethink both transfusion therapy as a whole and the organization of the transfusion chain from donor to recipient. In this context, patient blood management (PBM) appears as an evidence-based, patient centred, multidisciplinary approach, aiming to optimise the care of patients who might need transfusion and consequently the use of blood products. This paper presents updated scientific bases of PBM and the three pillars founding it. As PBM is developing fast in other European countries, this review proposes ways to explore for its development in France. It finally proposes to integrate PBM in a wider and coordinated approach of the blood supply management, with tools to improve the effectiveness and efficiency of the transfusion chain, starting with the needs of the patients and ending with an optimum treatment of the patient, including the appropriate number of blood components of the required quality. A better understanding, implementation and assessment of this coordinated global approach, allowing to adapt donor collections to the patients' needs in compliance with safety requirements for patients and donors, in a coordinated way, will certainly be a major challenge for transfusion medicine in the near future, for the benefit of patients, donors and all other stakeholders involved in the transfusion chain.

    Full Text Available Ruby NI Pietersz, Pieter F van der Meer Department of Product and Process Development, Sanquin Blood Bank, Amsterdam, the Netherlands Abstract: This review focuses on safety improvements of blood processing of various blood components and their respective storage. A solid quality system to ensure safe and effective blood components that are traceable from a donor to the patient is the foundation of a safe blood supply. To stimulate and guide this process, National Health Authorities should develop guidelines for blood transfusion, including establishment of a quality system. Blood component therapy enabled treatment of patients with blood constituents that were missing, only thus preventing reactions to unnecessarily transfused elements. Leukoreduction prevents many adverse reactions and also improves the quality of the blood components during storage. The safety of red cells and platelets is improved by replacement of plasma with preservative solutions, which results in the reduction of isoantibodies and plasma proteins. Automation of blood collection, separation of whole blood into components, and consecutive processing steps, such as preparation of platelet concentrate from multiple donations, improves the consistent composition of blood components. Physicians can better prescribe the number of transfusions and therewith reduce donor exposure and/or the risk of pathogen transmission. Pathogen reduction in cellular blood components is the latest development in improving the safety of blood transfusions for patients.

    Full Text Available Background/Aim. In spite of the evidence suggesting a significant morbidity associated with blood transfusions, the use of blood and blood products remain high in cardiac surgery. To successfully minimize the need for blood transfusion, a systematic approach is needed. The aim of this study was to investigate the influence of different anesthetic techniques, general vs combine epidural and general anesthesia, as well as different surgery strategies, on-pump vs off-pump, on postoperative bleeding complications and the need for blood transfusions during perioperative period. Methods. Eighty-two consecutive patients scheduled for coronary artery bypass surgery were randomized according to surgical and anesthetic techniques into 4 different groups: group 1 (patients operated on off-pump, under general anesthesia; group 2 (patients operated on off-pump, with combined general and high thoracic epidural anesthesia; group 3 (patients operated on using standard revascularization technique, with the use of extracorporeal circulation, under general anesthesia, and group 4 (patients operated on using standard revascularization technique, with the use of extracorporeal circulation, with combined general and high thoracic epidural anesthesia. Indications for transfusion were based on clinical judgment, but a restrictive policy was encouraged. Bleeding was considered significant if it required transfusion of blood or blood products, or reopening of the chest. The quantity of transfused blood or blood products was specifically noted. Results. None of the patients was transfused blood or blood products during the surgery, and as many as 70/81 (86.4% patients were not transfused at all during hospital stay. No difference in postoperative bleeding or blood transfusion was noted in relation to the type of surgery and anesthetic technique applied. If red blood cells were transfused, postoperative bleeding was the most influential parameter for making clinical

    Full Text Available OBJECTIVE: This study aimed to compare the storage properties of red blood cell (RBC concentrates of umbilical cord blood (UCB and adult donor blood (ADB, and to evaluate the feasibility of UCB-RBC concentrate as an autologous source for blood transfusion in very low birth weight (VLBW preterm neonates. METHODS: In all, 30 newborn (10 preterm, 20 full term UCB and 31 ADB units were collected. RBC concentrates were stored and compared with regard to pH, potassium (K+, 2,3-biphosphoglycerate (2-3-BPG, adenosine tri-phosphate (ATP, plasma Hb, and bacterial contamination on d 1, 21, and 35 of storage. RESULTS: The K+ level increased with time and differed significantly between storage d 1 and 21, and between storage d 1 and 35 in both the UCB and ADB units. Initial and d 21 K+ levels were higher in the UCB units than in the ADB units. The 2,3-BPG level did not differ significantly between the UCB-PRC and ADB-PRC samples. After 35 d of storage both UCB-PRC and ADB-PRC samples exhibited significant differences from the initial free Hb, intracellular ATP, and pH values. Significant differences in intracellular ATP and pH were also observed between the UCB-PRC and ADB-PRC samples. CONCLUSION: The volume of harvested and prepared UCB-PRC can be used for some of the blood transfusions required during the neonatal period and thus may decrease the number of allogeneic transfusions, especially in preterm newborns. The hematological and biochemical changes that occurred in UCB during storage were comparable with those observed in ADB, and do not pose a risk to the immature metabolism of neonates. UCB-RPC prepared and stored under standard conditions can be a safe alternative RBC source for transfusions in VLBW newborns.

    Full Text Available Aim: The study aims to determine the frequency of homologous blood transfusion in patientsundergoing cleft lip and palate surgery at the Lagos University Teaching Hospital, Nigeria. Setting and Design: A prospective study of transfusion rate in cleft surgery conducted at the Lagos University Teaching Hospital, Nigeria. Material and Methods: One hundred consecutive patients who required cleft lip and palate surgery were recruited into the study. Data collected included age, sex and weight of patients, type of cleft defects, type of surgery done, preoperative haematocrit, duration of surgery, amount of blood loss during surgery, the number of units of blood cross-matched and those used. Each patient was made to donate a unit of homologous blood prior to surgery. Results: There were 52 females and 48 males with a mean age of 64.4 ± 101.1 months (range, 3-420 months. The most common cleft defect was isolated cleft palate (45% followed by unilateral cleft lip (28%. Cleft palate repair was the most common procedure (45% followed by unilateral cleft lip repair (41%. The mean estimated blood loss was 95.8 ± 144.9 ml (range, 2-800ml. Ten (10% patients (CL=2; CP=5, BCL=1; CLP=2 were transfused but only two of these were deemed appropriate based on percentage blood volume loss. The mean blood transfused was 131.5 ± 135.4ml (range, 35-500ml. Six (60% of those transfused had a preoperative PCV of < 30%. Only 4.9% of patients who had unilateral cleft lip surgery were transfused as compared with 50% for CLP surgery, 11% for CP surgery, and 10% for bilateral cleft lip surgery. Conclusions: The frequency of blood transfusion in cleft lip and palate surgery was 10% with a cross-match: transfusion ratio of 10 and transfusion index of 0.1. A "type and screen" policy is advocated for cleft lip and palate surgery.

    2009-10-01

    Full Text Available Allogeneic blood transfusion (ABT is frequently used as the first therapeutic option for the treatment of acute anaemia in patients with inflammatory bowel disease (IBD, especially when it developed due to gastrointestinal or perioperative blood loss, but is not risk-free. Adverse effects of ABT include, but are not limited to, acute hemolytic reaction (wrong blood or wrong patient, febrile non-hemolytic transfusional reaction, bacterial contamination, transfusion-related acute lung injury, transfusion associated circulatory overload, transfusion-related immuno-modulation, and transmission of almost all infectious diseases (bacteria, virus, protozoa and prion, which might result in increased risk of morbidity and mortality. Unfortunately, the main physiological goal of ABT, i.e. to increase oxygen consumption by the hypoxic tissues, has not been well documented. In contrast, the ABT is usually misused only to increase the haemoglobin level within a fixed protocol [mostly two by two packed red blood cell (PRC units] independently of the patient’s tolerance to normovolemic anaemia or his clinical response to the transfusion of PRC units according to a “one-by-one” administration schedule. Evidence-based clinical guidelines may promote best transfusion practices by implementing restrictive transfusion protocols, thus reducing variability and minimizing the avoidable risks of transfusion, and the use of autologous blood and pharmacologic alternatives. In this regard, preoperative autologous blood donation (PABD consistently diminished the frequency of ABT, although its contribution to ABT avoidance is reduced when performed under a transfusion protocol. In addition, interpretation of utility of PABD in surgical IBD patients is hampered by scarcity of published data. However, the role of autologous red blood cells as drug carriers is promising. Finally, it must be stressed that a combination of methods used within well-constructed protocols

    Full Text Available Iron chelation therapy is often used to treat iron overload in patients requiring transfusion of red blood cells (RBC. A 76-year-old man with MDS type refractory cytopenia with multilineage dysplasia, intermediate-1 IPSS risk, was referred when he became transfusion dependent. He declined infusional chelation but subsequently accepted oral therapy. Following the initiation of chelation, RBC transfusion requirement ceased and he remained transfusion independent over 40 months later. Over the same time course, ferritin levels decreased but did not normalize. There have been eighteen other MDS patients reported showing improvement in hemoglobin level with iron chelation; nine became transfusion independent, nine had decreased transfusion requirements, and some showed improved trilineage myelopoiesis. The clinical features of these patients are summarized and possible mechanisms for such an effect of iron chelation on cytopenias are discussed.

    Clinicians sometimes are confronted with the challenge of transfusing haemorrhaging Rhesus (Rh) D negative patients with Rh D positive blood to save their lives. There are concerns about alloimmunization and future haemolytic disease of the newborn in women of the reproductive age. Another fear is transfusion reaction if they receive another Rh D positive blood in future. We present a 32-year-old Rh D negative woman, who had postpartum haemorrhage in her first pregnancy and was transfused with Rh D positive blood because of unavailability of Rh D negative blood. She did not receive anti D immunoglobin but subsequently had a normal term pregnancy of an Rh positive fetus without any detectable anti D antibodies throughout the pregnancy. In life threatening situations from obstetric haemorrhage, transfusion of Rh D negative women with Rh D positive blood should be considered as the last resort. PMID:26339087

    Serum erythropoietin (sEPO) level is known to increase as hemoglobin (Hb) concentration decreases during and after preoperative autologous blood donation (PAD). The endogenous erythropoietin (EPO) production after allogeneic blood transfusion has not to our knowledge, been studied. The aim of the present study was to determine whether there is, after surgery, any change in sEPO concentration after allogeneic blood transfusion, and whether there is any difference in EPO response after autologous or allogeneic blood transfusion. Thirty-one patients approaching total hip-joint replacement surgery, were randomized to receive either allogeneic red blood cells (n = 15) or predeposited autologous whole blood transfusion (n = 16). The relationship between Hb, sEPO, and reticulocytes in the recipients were repeatedly analyzed before, during and after surgery. The Hb followed an expected pattern, with a decreased concentration after PAD in the autologous group, then in both groups after surgery. The sEPO concentration was significantly higher in the allogeneic than in the autologous group on day one and day 4-5 postoperatively. The reticulocyte level, on the contrary, was higher in the autologous patients before, one hour after, and one day after surgery. The study showed a greater increase in sEPO concentration after allogeneic blood transfusion than after autologous blood transfusion. There may be an inverse relationship between sEPO and the reticulocyte level. PMID:12509214

    There is a lack of consensus on the safety of the coadministration of drugs and red blood cells (RBCs). A systematic review was undertaken to establish the evidence base for this question and assess how the evidence may be translated into present clinical day practice. Comprehensive searches of MEDLINE, EMBASE, CINAHL, the Cochrane Library and hand searching of transfusion journals, guidelines and websites identified 12 relevant papers: 11 in-vitro experiments and 1 case report. Data on incidences of haemolysis and agglutination following coadministration were extracted and analysed. Overall findings suggest that iron chelators (two papers), antimicrobials (three papers) and lower doses of opioids (three papers) are safe to coadminister with RBCs. Haemolysis was observed with higher doses of opioids (three papers). Transposition of these findings to clinical practice is limited because of the lack of clinical applicability of in-vitro experiments and diversity in how, and what, clinical outcome measures were used. Further evidence from true clinical settings would be required to inform clinical practice on the efficacy and safety of the coadministration of drugs and RBCs. PMID:19302450

    Full Text Available AIMS: For elective surgeries, over ordering of blood is a common practice. This can be decreased by simple means of changing the blood cross matching and ordering schedule depending upon the type of surgery performed. The principle aim of the study was to improve the efficacy of ordering system for maximum utilisation of blood and formulation of maximum surgical blood order schedule (MSBOS for procedures where a complete cross-match appears mandatory. MATERIAL AND METHODS: We evaluated blood ordering and transfusion practices in 500 elective general surgical procedures at our institute. With the help of different indices such as cross-match to transfusion ratio (C/T ratio, transfusion probability (% T and transfusion index (TI, blood ordering pattern was changed in the next 150 patients. RESULTS: Out of 1145 units of blood crossmatched for the first 500 patients only 265 were transfused with non-utilisation of 76.86% of ordered blood. With the help of the indices the wastage was reduced in next 150 patients, i.e. from 76.86% to 25.26% and improved the utilisation of blood, i.e. from 23.14% to 74.74%. CONCLUSIONS: Change of blood ordering patterns with use of MSBOS can avoid the over ordering of blood.

    2009-07-01

    Medicare, an important payer for hospitals, reimburses hospitals for inpatient stays using Diagnosis Related Groups (DRGs). Many private insurers also use the DRG methodology to reimburse hospitals for their services. Therefore, those blood service organizations that bill Medicare directly require an understanding of the DRG system of payment to enable them to bill Medicare correctly, and in order to be certain they are adequately reimbursed. Blood centers that do not bill Medicare directly need to understand how hospitals are reimbursed for blood and blood components as this affects a hospital's ability to pay service fees related to these products. This review presents a detailed explanation of how hospitals are reimbursed by the Centers for Medicare and Medicaid Services (CMS) for Medicare inpatient services, including blood services.

    2004-06-01

    Full Text Available Abstract Background The risk compensation theory is a widely used concept in transport economics to analyze driver risk behaviour. This article explores the feasibility of applying the theory in blood transfusion to raise important questions regarding the increased blood safety measures and their possible effects on blood usage (e.g., the appropriateness in transfusion. Further, it presents the findings of a pilot survey of physicians in Canada. Discussion While studies have attempted to define transfusion appropriateness, this article argues that if the risk compensation theory holds true for transfusion practice, physicians may actually be transfusing more. This may increase the possibility of contracting other unknown risks, such as the variant Creutzfeldt-Jakob Disease (vCJD, as well as increasing the risk of non-infectious transfusion risks, such as transfusion reactions. Summary A much larger study involving psychosocial assessment of physician decision making process to fully assess physician behaviour within the context of risk compensation theory and transfusion practice in Canada is needed to further explore this area.

    Full Text Available Background: During orthotopic liver transplantation (OLT, activation of the fibrinolytic system can contribute significantly to perioperative bleeding. Prophylactic administration of antifibrinolytic agents has been shown to reduce blood loss and the need for allogenic transfusion. Objective: To study the effect of antifibrinolytics on requirement of blood components, blood loss and operative time during OLT in patients with end stage liver disease, reporting to a single centre. Materials and Methods: Consecutive patients who underwent OLT at this centre during the period February 2003-October 2007 were the subjects of this study. Based on the individual anesthesiologist′s preference, patients were assigned to receive either two million units of aprotinin (AP as a bolus followed by 5,00,000 units/hour or 10 mg/kg tranexamic acid (TAas a bolus followed by 10 mg/kg every six to eight hours, administered from the induction till the end of the surgery. Transfusion policy was standardized in all patients. Intraoperative red cell salvage was done wherever possible. The effect of these two antifibrinolytic drugs on transfusion requirement was evaluated as a whole and in a sub group of patients from each treatment group and compared with a concurrent control group that did not receive antifibrinolytic drugs. Results: Fifty patients (40 M / 10 F, 44 adults, 6 pediatric patients underwent OLT in the study period. Fourteen patients were given AP, 25 patients were given TA and 11 patients did not receive any of the agents(control group.

    Background Perioperative red blood cell transfusions (RBC) are associated with increased morbidity and mortality after cardiac surgery. Acute normovolemic hemodilution (ANH) is recommended to reduce perioperative transfusions; however, supporting data are limited and conflicting. We describe the relationship between ANH and RBC transfusions after cardiac surgery using a multi-center registry. Methods We analyzed 13,534 patients undergoing cardiac surgery between 2010 and 2014 at any of the 26 hospitals participating in a prospective cardiovascular perfusion database. The volume of ANH (no ANH, HCT, and center. Results ANH was used in 17% of the patients. ANH was associated with a reduction in RBC transfusions (RRadj 0.74, p <0.001). Patients having ≥800mL of ANH had the most profound reduction in RBC transfusions (RRadj 0.57, p<0.001). Platelet and plasma transfusions were also significantly lower with ANH. The ANH population had superior postoperative morbidity and mortality compared to the no ANH population. Conclusions There is a significant association between ANH and reduced perioperative RBC transfusion in cardiac surgery. Transfusion reduction is most profound with larger volumes of ANH. Our findings suggest the volume of ANH, rather than just its use, may be an important feature of a center’s blood conservation strategy. PMID:26206721

    Objective: To explore the influence of perioperative blood transfusion on the postoperative survival of patients with colon cancer. Methods: Univariate and multivariate retrospective analyses were performed on the survival in a total of 723 colon cancer patients which were treated surgically during a period of 10 years. Results: Kaplan-Meicr estimates showed that more than 800 mL perioperative blood transfusion was the survival predictor. Blood transfusion influenced significantly the prognosis of patients 40 years old and younger, those undergoing helicoloectomy left side, those with papillary adenocarcinoma,those with big tumors (diameter ≥8 em), those with stage I tumors, those with lymphatic node metastases and those without liver metastases. In multivariate analysis only the tumor location, radicality of operation, lymphatic invasion, liver metastasis, depth of tumor invasion and TNM stage retained their significance. Conclusion: Perioperative blood transfusion is the prognostic factor for patients with colon cancer to some extent. The indication of blood transfusion must be restricted strictly, specially in patients younger than 40 years old, with right side lesion, papillary adenocarcinoma, big tumors (diameter ≥8 em), stage I tumors and lymphatic node metastases or without liver metastases. But perioperative blood transfusion may not be deleterious for patients with staging Ⅳ disease and with distant metastases.

  3. Effect of total lymphoid irradiation and pretransplant blood transfusion on pancreatic islet allograft survival

    International Nuclear Information System (INIS)

    Total lymphoid irradiation (TLI) has been shown to have a strong immunosuppressive effect both experimentally and clinically. Pretransplant blood transfusions have also been shown to have a strong beneficial effect in the outcome of organ transplantation. A study was made of the effect of TLI and pretransplant blood transfusions, alone and in combination, as an immunosuppressive modality in the isolated pancreatic islet transplant in the rat model. Donor rats (Fischer RT1v1) were kept on a 50% DL-ethionine supplemented diet for 4-6 weeks prior to pancreas removal. Recipient rats (Lewis RT1) were made diabetics prior to transplantation by iv injection of streptozotocin (45 mg/kg). Transfusion protocol consisted of a biweekly transfusion of 2 ml of either donor specific or third party transfusions. Total lymphoid irradiation was carried out by daily administration of 200 rads during one week prior to transplantation. Transplantation of the isolated islets was performed by intraportal injection. Syngeneic transplant of one and a half donor pancreata in each recipient reverted the diabetic condition indefinitely (greater than 100 days). Untreated allogenic grafts had a mean survival time (MST) of 5.2 days. Total lymphoid irradiation in dosages of 800, 1000, and 1200 rads, as the only immunosuppressive regimen, prolonged the MST of allografts to 15.3, 16.5, and 21.8 days, respectively (P less than .05). Pretransplant third party blood transfusion had no effect on allograft survival (MST 6.0). When donor specific blood transfusions were given, the MST was prolonged to 25.3 days (P less than .05). When TLI was administered to recipients of donor specific transfusions, the MST of the allografts did not show any statistical significant difference when compared with untreated animals. This abrogation of the beneficial effect of specific blood transfusion was observed in all dosages of TLI employed: 800 rad (MST 3.0), 1000 rad (MST 8.0), 1200 rad (MST 5.18)

    Full Text Available Abstract Background Oesophagectomy for cancers is a major operation with significant blood loss and usage. Concerns exist about the side effects of blood transfusion, cost and availability of donated blood. We are not aware of any previous study that has evaluated predictive factors for perioperative blood transfusion in patients undergoing elective oesophagectomy for cancer. This study aimed to audit the pattern of blood crossmatch and to evaluate factors predictive of transfusion requirements in oesophagectomy patients. Methods Data was collected from the database of all patients who underwent oesophagectomy for cancer over a 2-year period. Clinico-pathological data collected included patients demographics, clinical factors, tumour histopathological data, preoperative and discharge haemoglobin levels, total blood loss, number of units of blood crossmatched pre-, intra- and postoperatively, number of blood units transfused, crossmatched units reused for another patient and number of blood units wasted. Clinico-pathological variables were evaluated and logistic regression analysis was performed to determine which factors were predictive of blood transfusion. Results A total of 145 patients with a male to female ratio of 2.5:1 and median age of 68 (40–85 years were audited. The mean preoperative haemoglobin (Hb was 13.0 g/dl. 37% of males (Hb 70 years, Hb level Conclusion The cohort of patients audited was over-crossmatched. The identified independent predictors of blood transfusion should be considered in preoperative blood ordering for oesophagectomy patients. This study has directly led to a reduction in the maximum surgical blood-ordering schedule for oesophagectomy to 2 units and a reaudit is underway.

    Full Text Available Background: Blood transfusion is predominantly a hospital-based practice in many resourceconstrained economies like Nigeria, wherein the sourcing, storage, processing and clinical use of blood and blood products resides in the often financial and manpower constrained hospitals. Aim: To identify the ethical and legal issues related to hospital-based blood transfusion practice for medical practitioner. Methods: Relevant articles retrieved via PubMed/MEDLINE and Google scholar search engines were used. Results: This review found that, medical practitioners are directly or vicariously liable in professional negligence in hospital-based transfusion injuries. The potential weaknesses in hospital-based blood transfusion practice as ethically identified include; transfusion transmissible infections, blood group incompatibility, haemolytic transfusion reaction, failure to obtain informed consent and challenges of haemovigillance. However from the cases considered, medical practitioners are more professionally liable where they withhold a transfusion or transfuse blood group incompatible transfusion or fail to obtain an informed consent for blood transfusion especially amongst Jehovah’s Witness adherents. Conclusion: Medical practitioners at hospital-based transfusion centres are professionally liable for negligence due to blood transfusion injuries by their clinical, laboratory or general administrative oversight at different levels of hospital management. It is recommended that, they carry out this duty cautiously. While error reporting should be encouraged, litigations against them should be pursued cautiously in order not to encourage defensive blood transfusion practices in fear of claims or litigations to the disadvantage of the patients. Mediation or arbitration systems which are faster, less expensive and often less punitive but help strengthen the blood transfusion services should be encouraged.

    Full Text Available OBJECTIVE: To evaluate the association of clinical and demographic variables in patients requiring blood transfusion during elective surgery to treat scoliosis with the aim of identifying markers predictive of the need for blood transfusion. METHODS: Based on the review of medical charts at a public university hospital, this retrospective study evaluated whether the following variables were associated with the need for red blood cell transfusion (measured by the number of packs used during scoliosis surgery: scoliotic angle, extent of arthrodesis (number of fused levels, sex of the patient, surgery duration and type of scoliosis (neuromuscular, congenital or idiopathic. RESULTS: Of the 94 patients evaluated in a 55-month period, none required a massive blood transfusion (most patients needed less than two red blood cell packs. The number of packs was not significantly associated with sex or type of scoliosis. The extent of arthrodesis (r = 0.103, surgery duration (r = 0.144 and scoliotic angle (r = 0.004 were weakly correlated with the need for blood transfusion. Linear regression analysis showed an association between the number of spine levels submitted to arthrodesis and the volume of blood used in transfusions (p = 0.001. CONCLUSION: This study did not reveal any evidence of a significant association between the need for red blood cell transfusion and scoliotic angle, sex or surgery duration in scoliosis correction surgery. Submission of more spinal levels to arthrodesis was associated with the use of a greater number of blood packs.

    Despite leukoreduced red blood cells (LR-RBCs) reducing the risk of transfusion-related acute lung injury (TRALI), we present a case of a 16-year-old female with kyphosis who received a transfusion of one unit of LR-RBCs, which lead to life-threatening, intraoperative TRALI. The clinical presentation included pulmonary edema, severe postoperative lactic acidosis, left ventricular dysfunction, increased creatine phosphokinase, fatty infiltration of the liver, and hemodynamic instability requiring inotropic support. This presentation is not the classic description of TRALI. Our patient improved with supportive treatment and was successfully extubated on postoperative day 4. TRALI work-up revealed antibody formation to HLA A2, A68, B44, and DQA 5 for the LR-RBCs unit administered. PMID:26126598

    International Nuclear Information System (INIS)

    To compare the number and volume of red blood cell transfusions (RBCTs) in very low birth weight infants under restrictive red blood cell transfusion guidelines with and without erythropoietin administration. In a controlled clinical trial conducted at the neonatal intensive care unit of Alzahra Hospital, Isfahan, Iran, between April 2002 to April 2004, 60 premature infants with gestational age up to 34 weeks, birth weight up to 1500 g, and postnatal age between 8 and 14 days were included. The newborns were randomized into 2 groups: Group 1 received 3 doses of 400 IU/kg erythropoietin per week for 6 weeks, and Group 2 received no treatment aside from their conventional medications. The 2 groups did not differ significantly with respect to their mean gestational age, birth weight and hematocrit at the study entry. Fewer transfusions were administered to those receiving erythropoietin (26.7% versus 50%, p=0.03), but there was no statistically significant difference between groups with respect to volume of transfusion. Compared with the placebo group, the infants receiving erythropoietin had a higher mean hematocrit (34% +/- 4.3 versus 29% +/- 5.9, p<0.001) and absolute reticulocyte count (57 +/- 19 versus 10 +/- 4.8 x 106, p<0.001) at the end of the study. We found no significant difference in the incidence of thrombocytopenia and leukopenia between the 2 groups. We conclude that when the restrictive RBCT guidelines were followed, treatment with erythropoietin can be useful in reduction of the number of RBCTs. (author)

    This study was undertaken to investigate the changes in recipient serum electrolytes and arterial blood gas after irradiated blood transfusion. We measured electrolytes and arterial blood gas before and after the transfusion during elective surgery in 55 patients. The mean blood loss was 1,477 g and the mean transfused blood unit of irradiated Mannitol-Adenine-Phosphate (MAP) was 5.9 units. Potassium concentration increased from 3.8 to 4.2 mEq·l-1. A total of 187 units, which had been stored for 12.3±3.5 days after donation and for 5.1±3.8 days after irradiation, was used. There was a significant correlation between the storage period from the day of irradiation and the potassium concentration of the supernatant (r=0.56, p<0.0001). This study recommends that a safe transfusion rate of irradiated blood should be determined because the high potassium concentration of irradiated blood may lead to lethal complications in case of rapid transfusion.

    2006-02-01

    The effect of blood transfusion on outcomes in esophageal surgery remains controversial. The contrasting conclusions drawn from a number of retrospective analyses with different methodologies create a landscape that is difficult to interpret. Because of the scope of esophageal resection, the need for blood transfusion cannot be eliminated. What recommendations then, if any, can be made for the practicing surgeon? First, surgeons and anesthesiologists need to reevaluate their transfusion thresholds. The age-old practice of keeping the hemoglobin above 10 g/dL has very little evidence-based support. A multicenter, randomized, controlled clinical trial in Canada demonstrated that a restrictive strategy of blood transfusion, in which patients were transfused only for a hemoglobin level of less than 7 g/dL, was at least as effective as and possibly was superior to a liberal transfusion strategy in critically ill patients. It has also been estimated that more than 25% of patients undergoing colorectal resections may receive at least one unit of unnecessary blood. Further, the immediate reduction in the hemoglobin concentration caused by the normovolemic hemodilution associated with surgery and crystalloid fluid replacement is not associated with any increased morbidity or mortality. If these data are examined in the context of the results of Langley and Tachibana indicating that a threshold amount of blood needs to be transfused to impact outcomes, it becomes even more important to limit transfusion to only the amount that is essential. Thus, surgeons and anesthesiologists should adopt a more stringent set of requirements for blood transfusion. Second, with the proven feasibility and reduction in infectious complications associated with autologous blood-donation programs, any patient who meets the criteria discussed here should be encouraged to participate in such a program. Although the effect of autologous blood on cancer outcomes remains unclear, the other advantages

    Red blood cell transfusions have been cited as one of the most overused therapeutic interventions in the USA. Excessively aggressive transfusion practices may be driven by mandatory physician notification of critical hemoglobin values that do not generally require transfusion. We examined the effect of decreasing the critical value of hemoglobin from 8 to 7 g/dL at our institution. Along with this change, mandatory provider notification for readings between 7 and 8 g/dL was rescinded. Transfusion rates were compared retrospectively during paired 5-month periods for patients presenting in three key hemoglobin ranges (6.00–6.99, 7.00–7.99, and 8.00–8.99 g/dL). A change in transfusion practices was hypothesized in the 7–8 g/dL range, which was no longer labeled critical and for which mandated physician calls were rescinded. Transfusion rates showed a statistically significant 8% decrease (P≤0.0001) during the 5-month period post change in our transfusion practices. This decrease in the 7.00–7.99 g/dL range was significantly greater than the 2% decrease observed in either the 6–6.99 g/dL (P=0.0017) or 8–8.99 g/dL (P≤0.0001) range. Cost savings of up to $700,000/year were extrapolated from our results showing 491 fewer units of red blood cells transfused during the 5-month post change. These cost savings do not take into account the additional impact of complications associated with blood transfusions. PMID:27350757

    Full Text Available Background: Massive transfusion protocols (MTPs are increasingly used in the transfusion practice and are developed to provide the standardized and early delivery of blood products and procoagulant agents and to supply the transfusion of blood products in a well-balanced ratio. Aim: The aim of this study was to investigate the effect of a hospital-wide introduction of an MTP on blood product ratio and a waste of blood products. Materials and Methods: Retrospective analysis was performed to compare the transfusion practice in massive bleeding patients before and after the introduction of an MTP and between the use of an MTP and transfusion off-protocol. Massive bleeding was defined as an administration of ≥5 units of red blood cells (RBCs within 12 h. Results: Of 547 massively transfused patients, 192 patients were included in the pre-MTP period and 355 patients in the MTP period. The ratio of RBC to fresh frozen plasma (FFP and the platelets transfused shifted significantly toward 1:1:1 in the MTP period (P = 0.012. This was mainly caused by a shift in RBC: FFP ratio (P = 0.014. An increase in the waste of blood products was observed, most notably FFPs (P = 0.026. Extending the storage time after thawing reduced the waste of FFPs from 11% to 4%. Conclusion: Hospital-wide introduction of an MTP is an adequate way to achieve a well-balanced transfusion ratio of 1:1:1. This comes at the cost of an increase in the waste of FFPs, which is lowered after extending the duration of storage time after thawing.

    Full Text Available Antecedents and objectives: Cardiac surgery has been a process which traditionally requires large amounts of homologous blood transfusions. Due to the negative effects on perioperativemorbimortality, and its cost, some alternatives have been developed in order to reduce or avoid giving a transfusion to the patients. The aim of this study is to put into practice and assess theeffectiveness of a strategy for reducing the use of allogeneic transfusions in the cardiac surgery perioperative at the Ernesto Che Guevara Cardiology Hospital. Method: 151 patients, who were operated on with or without extracorporeal circulation, and who were inserted in a blood saving program that included acute intentional normovolemic hemodilution with autotransfusion during theyear 2008, were studied in order to assess the effectiveness of such strategies. Results: It was possible to avoid the transfusions with allogeneic components in 55 percent of the patients (56.0 percent from the group intervened with extracorporeal circulation (ECC, and 52.64 percent of the patients operated on without ECC and the patients who received the transfusions needed a smaller amount of allogeneic blood components, as well as fewer units administered through the transfusion. Conclusions: The strategies for saving blood were effective in order to reduce the homologous transfusions in the cardiac surgery perioperative.

    Optimal selection of blood donors is critical for ensuring the safety of blood products. The current selection process is concerned principally with the safety of the blood donor at the time of donation and of the recipient at the time of transfusion. Recent evidence suggests that the characteristics of the donor may affect short- and long-term transfusion outcomes for the transfused recipient. We conducted a systematic review with the primary objective of assessing the association between blood donor characteristics and red blood cell (RBC) transfusion outcomes. We searched MEDLINE, EMBASE, and Cochrane Central databases and performed manual searches of top transfusion journals for all available prospective and retrospective studies. We described study characteristics, methodological quality, and risk of bias and provided study-level effect estimates and, when appropriate, pooled estimates with 95% confidence intervals using the Mantel-Haenszel or inverse variance approach. The overall quality of the evidence was graded using Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. From 6121 citations identified by our literature search, 59 studies met our eligibility criteria (50 observational, 9 interventional). We identified the evaluation of association of 17 donor characteristics on RBC transfusion outcome. The risk of bias and confounding of the included studies was high. The quality of evidence was graded as very low to low for all 17 donor characteristics. Potential associations were observed for donor sex with reduced survival at 90 days and 6 months in male recipients that receive donated blood from females (hazard ratio 2.60 [1.09, 6.20] and hazard ratio 2.40 [1.10, 5.24], respectively; n = 1), Human Leukocyte Antigen - antigen D Related (HLA-DR) selected transfusions (odds ratio [OR] 0.39 [0.15, 0.99] for the risk of transplant alloimmunization, n = 9), presence of antileukocyte antibodies (OR 5.84 [1.66, 20.59] for risk

Out of the 25 cases, 15 were of Rhesus (Rh HDN, while ABO and other blood groups constituted 6 and 4 HDN cases respectively. First, the neonates′ and mother′s blood samples were subjected to relevant investigations. After that, for neonates having Rh HDN, O Rh negative cells suspended in AB plasma were given, O Rh positive cells suspended in AB plasma were given to ABO HDN; and O positive cells, which were indirect Coomb′s cross-matched compatible with neonates′ and mother′s serum / plasma, suspended in AB plasma were given to the neonates having HDN because of other blood group antibodies. The exchange transfusion (ET was carried out taking all aseptic precautions by Push-Pull technique with double-volume exchange transfusion method. The average post-exchange fall in serum indirect bilirubin was (52.01% in all 25 cases, which was found to be more significant than the previous studies. Looking into the superiority of the exchange transfusion in HDN by reconstituted blood, the reconstituted blood can be modified and supplied as per the requirement and conditions.

    Data from the Australian Better Safer Transfusion programme show that about one-third of patients undergoing hip or knee arthroplasty receive perioperative blood transfusions, placing them at increased risk for adverse clinical outcomes. Other concerns associated with allogeneic blood transfusion include the quality of stored red cell concentrates, the cost of provision of blood and the predicted local demographics, which mean that fewer donors will need to support a greater number of recipients. In view of the multiple challenges associated with allogeneic blood transfusion and its provision, we developed practical management recommendations for perioperative bleeding in joint replacement surgery, based on available evidence and expert consensus opinion, that aim to promote a new, responsible approach to transfusion management. Key recommendations are as follows. Patients' medical health, including haemoglobin and iron levels, needs to be evaluated and optimized preoperatively. Anticoagulant and antiplatelet therapy should be stopped if possible, unless indicated for secondary cardiovascular prevention or coronary stent patency, in which case careful consideration is required. If substantial blood loss is anticipated, intraoperative management with antifibrinolytic agents is recommended for bleeding prophylaxis. Normothermia should be maintained. Pharmacological and non-pharmacological measures are recommended for post-operative thromboprophylaxis. A blood management programme should be instituted for haemodynamically stable patients.

    Anemia is common in critically ill patients. While the goal of transfusion of red blood cells (RBCs) is to increase oxygen carrying capacity, there are contradictory results about whether RBC transfusion to treat moderate anemia (e.g. hemoglobin 7–10 g/dL) improves tissue oxygenation or changes outcomes. While increasing levels of anemia eventually lead to a level of critical oxygen delivery (DO2), increased cardiac output and oxygen extraction are homestatic mechanisms the body uses to preve...

    2006-06-01

    Blood transfusions transmit HIV more effectively than other means, yet there has been little examination of their role in the origins and early course of AIDS in sub-Saharan Africa. We review historical data in archives, government reports, and medical literature from African and European sources documenting the introduction, establishment, use, and growth of blood transfusions in sub-Saharan Africa. These data allow estimation of the geographic diffusion and growth of blood transfusions between 1940 and 1990. By 1955, 19 African colonies and countries reported transfusion programs-with national rates of 718 to 1372 per 100 000 by 1964, and urban rates similar to those in developed countries. We estimated 1 million transfusions per year in sub-Saharan Africa by 1970 and 2 million per year by the 1980s, indicating that transfusions were widely used throughout sub-Saharan Africa during the crucial period of 1950-1970, when all epidemic strains of HIV first emerged in this region.

    Full Text Available Abstract Background Blood transfusion is a common therapy for multiple trauma patients, and is often performed soon after hospital admission. It is unclear whether the need for a blood transfusion in multiply injured patients presenting with a positive blood alcohol concentration (BAC is associated with increased morbidity/mortality, since their risk behavior differs significantly from patients with a negative BAC. In this study, we evaluated the role of blood transfusion in the treatment of BAC-positive multiple trauma patients. Patients In a three-year period, 164 patients at a single trauma center presented with a positive BAC, and 145 met the inclusion criteria for further evaluation and regression analysis. We compared patients who were transfused (n = 76 with those who were not transfused (n = 69. Results In both groups, the most common causes of trauma were traffic accidents and falls. Most patients were admitted to the hospital from the scene of the accident (77.2% and were male (89.0%. Transfused patients had a lower GCS (p ≤ .001 and her ISS (p ≤ .001, were more likely to have severe head injuries (p ≤ .001, tended to have higher BACs (p = .053, had lower hemoglobin levels and prothrombin times in the first 24 hours (p ≤ .001, had lower lactate levels, had higher rates of intubation (p ≤ .001 and ICU admission, and had longer ICU stays and artificial ventilation times (p ≤ .001. Mortality was significantly higher in transfused patients (n = 15 vs. n = 3, p ≤ .001. Non-survivors were more likely to have severe head injuries; be intubated and ventilated; be older; have higher ISS scores, lactate levels, and numbers of transfusions in the first 24 hours; and have lower GCS scores, hemoglobin measurements, and prothrombin levels. In a binary logistic regression model, only age (p = .009 and ISS (p = .004 independently predicted mortality. Conclusion In our single-center study, the BAC of multiple trauma patients and the

  12. Risk of malaria transmission through blood transfusion and its detection by serological method

    International Nuclear Information System (INIS)

    Objective: To assess the risk of transmission of malaria through blood transfusion, and compare efficacy of testing by immuno chromatographic (ICT) devices vis a vis peripheral blood film (PBF). Results: Amongst healthy blood donors we did not find even a single case of malaria and there was no report of persistent post transfusion pyrexia. We are unable to comment on species frequency in blood donors. However, amongst known patients of malaria we found a higher frequency of Plasmodium viax(P.v) as compared to Plasmodium falciparum(P.f). Testing by serological method, helped us to diagnose 5% of our patients who were missed by peripheral blood films. Conclusion: Between properly selected voluntary non-remunerated blood donors the incidence of malaria transmission is zero and the blood is safe for transfusion. Serological testing shows good correlation with peripheral blood film detection. In fact, it can detect the disease even when film detection has been unsuccessful. If proper donor selection criteria are observed there is little risk of transmitting malaria through transfusion. However, as the donor pool in the Service is not necessarily totally the of voluntary non-remunerated donors and substantive numbers of replacement/first time, occasionally uneducated/unaware donors, are being bled, screening for malaria will not be totally unrewarding.

    Despite improvements in blood safety making transfusion a much safer clinical procedure, the general public still perceives it as risky. We systematically reviewed available literature to examine evidence regarding the reasons and causes behind this perception. Electronic databases including PubMed, Cochrane Library, and EMBASE for literature dating back to the 1980s were searched. Eligible studies collected information on blood recipients' demographics, measures of risk domains (sets of values that risks encompass), and general knowledge of blood transfusion in terms of risks and benefits. Each study was assessed for quality of data, research method, and relevant findings. A scoring system was used to subjectively rate the overall quality of each study. Each study was reviewed for its method of data collection and information abstracted on hazards and conceptual dimensions used to measure risk. Risk perception between blood transfusion and other hazards including alternatives to transfusion were compared. Fifteen studies met the inclusion criteria, all of which were conducted outside the United States, with most of the studies published more than 10 years ago and conducted by only 3 research groups. Five studies were rated as being very good, four good, five fair, and one of poor quality. The finding of the studies consistently show that objective or raw knowledge is not correlated with risk perception, but subjective or calibrated knowledge is. Thus, it is what people think they know rather than what they actually do know that influences risk perception of transfusion. Of the 3 common conceptual domains-dread, unknown risk, and benefits-blood transfusion was found to be of intermediate dread, intermediate unknown risk, and most beneficial compared with other hazards. Donated blood was found to have lower perceived risk than all other alternatives to transfusion, except for use of autologous blood. There is a lack of recent studies on allogeneic transfusion

    Objective:To explore the importance of irregular antibodies screening before blood transfusion. Methods:From March 2009 to March 2012,3 215 cases of patients with blood transfusion were selected as treatment group,and irregular antibody was detected before blood transfusion by polybrene method and microcolumn gel test. From January 2009 to February 2009,3 113 cases of patients with blood transfusion were selected as control group,and the incidence of adverse transfusion reaction was counted. Results:The positive rate of treatment group was 0. 40%,and the positive rate of female(0. 60%,10/1 500) was 3. 5 times of male(0. 17%, 3/1 715). Of the entire female positive,maternal positive rate was 1. 14%,8/701,4. 5 times of non-maternal(0. 25%,2/799). Depart-ment of hepatobiliary surgery,general surgery and nephrology have 10 cases of positive(76. 92%,10/13),while other departments have 3 only(23. 08%,3/13). The difference was statistically significant(P<0. 05). There were 29 cases of adverse transfusion reaction in control group(0. 93%),while 3 cases in treatment group(0. 093%). The difference has statistical significance(χ2 =9. 239,P <0. 05). Conclusion:Patients with pregnant history and department of hepatobiliary surgery,general surgery and nephrology are high-risk groups in blood transfusion.

    Rationale. By reducing cerebral oxygen delivery, anemia may aggravate traumatic brain injury (TBI) secondary insult. This study evaluated the impact of anemia and blood transfusion on TBI outcomes. Methods. This was a retrospective cohort study of adult patients with isolated TBI at a tertiary-care intensive care unit from 1/1/2000 to 31/12/2011. Daily hemoglobin level and packed red blood cell (PRBC) transfusion were recorded. Patients with hemoglobin < 10 g/dL during ICU stay (anemic group) were compared with other patients. Results. Anemia was present on admission in two (2%) patients and developed in 48% during the first week with hemoglobin < 7 g/dL occurring in 3.0%. Anemic patients had higher admission Injury Severity Score and underwent more craniotomy (50% versus 13%, p < 0.001). Forty percent of them received PRBC transfusion (2.8 ± 1.5 units per patient, median pretransfusion hemoglobin = 8.8 g/dL). Higher hospital mortality was associated with anemia (25% versus 6% for nonanemic patients, p = 0.01) and PRBC transfusion (38% versus 9% for nontransfused patients, p = 0.003). On multivariate analysis, only PRBC transfusion independently predicted hospital mortality (odds ratio: 6.8; 95% confidence interval: 1.1–42.3). Conclusions. Anemia occurred frequently after isolated TBI, but only PRBC transfusion independently predicted mortality. PMID:26605080

    Professional nurses must have the knowledge and skills to safely administer blood products and monitor for life-threatening complications. Nurse educators should ensure that student nurses also learn how to safely administer blood products; however students rarely have the opportunity to witness and manage adverse transfusion reactions. Despite the low incidence of rare adverse transfusion reactions, nursing students must be able to immediately recognize transfusion reactions, implement appropriate interventions, and communicate effectively with health care providers. To reinforce blood transfusion knowledge, practice technical skills, and promote management of adverse reactions, a human patient simulation experience was created for baccalaureate nursing students to provide application of related classroom content. Using a quasi-experimental design, students who received a related didactic lecture preceding the simulation were compared with students who did not receive the lecture. The lecture group's pre/posttest mean scores (n = 42) were significantly higher than the no lecture group's mean scores (n = 44). This simulation design included proper blood administration procedures, patient monitoring, management of transfusion reactions, and practice with interdisciplinary communication. Participation in a human patient simulation following a related didactic lecture may be useful to strengthen cognitive learning and help bridge the didactic-clinic gap. PMID:26073762

    The interim guidance issued by the World Health Organization during the West Africa 2014 Ebola outbreak provides guidelines on the use of convalescent blood from Ebola survivors for transfusion therapy. Here we develop a novel mathematical model, based on the interim guidance, to examine the nonlinear transmission-treatment-donation-stockpile dynamics during an Ebola outbreak and with a large scale use of the transfusion therapy in the population. We estimate the reduction of case fatality ratio by introducing convalescent blood transfusion as a therapy, and inform optimal treatment-donation-stockpile strategies to balance the treatment need for case fatality ratio reduction and the strategic need of maintaining a minimal blood bank stockpile for other control priorities.

    From about 1880 to 1920, a culture of medical experimentation promoted blood transfusion as a therapy for severe anemia in Europe, which was applied in German East Africa in 1892 for a case of blackwater fever, a complication of malaria afflicting mainly Europeans. This first case of blood transfusion in Africa, in which an African's blood was transfused into a German official, complicates the dominant narrative that blood transfusions in Africa came only after World War I. Medical researchers moreover experimented with blood serum therapies on human and animal subjects in Europe and Africa, injecting blood of different species, "races" and ethnicities into others to demonstrate parasite transmissibility and to discover vaccines for diseases such as malaria, sleeping sickness, and yellow fever. While research in German colonies is highlighted here, this was a transnational medical culture that crossed borders and oceans. This research is of interest as a possible early pathway for the epidemic spread of HIV and other zoonoses in Africa and the world, which biomedical researchers have identified as emerging in West-Central Africa sometime around the turn of the twentieth century.

    2013-01-01

    Full Text Available Chagas disease is caused by the protozoan parasite Trypanosoma cruzi and is endemic in many countries in Latin America, where infected bugs of the Triatominea subfamily carry the parasite in the gut and transmit it to humans through fecal contamination of a bite. However, vertical transmission and transmission through blood transfusion and organ transplantation is well documented. Increasing immigration from endemic countries to North America has prompted blood operators, including Canadian Blood Services and Hema Quebec, to initiate blood donor testing for Chagas antibody. In the present report, an unusual case of vertical transmission from a mother, most likely infected through blood transfusion, and detected as part of a concurrent seroprevalence study in blood donors is described.

    Full Text Available Abstract Background Cardiac surgery is a major consumer of blood products, and hemodilution increases transfusion requirements during cardiac surgery under CPB. As intraoperative parenteral fluids contribute to hemodilution, we evaluated the hypothesis that intraoperative fluid restriction reduces packed red-cell (PRC use, especially in transfusion-prone adults undergoing elective cardiac surgery. Methods 192 patients were randomly assigned to restrictive (group A, 100 pts, or liberal (group B, 92 pts intraoperative intravenous fluid administration. All operations were conducted by the same team (same surgeon and perfusionist. After anesthesia induction, intravenous fluids were turned off in Group A (fluid restriction patients, who only received fluids if directed by protocol. In contrast, intravenous fluid administration was unrestricted in group B. Transfusion decisions were made by the attending anesthesiologist, based on identical transfusion guidelines for both groups. Results 137 of 192 patients received 289 PRC units in total. Age, sex, weight, height, BMI, BSA, LVEF, CPB duration and surgery duration did not differ between groups. Fluid balance was less positive in Group A. Fewer group A patients (62/100 required transfusion compared to group B (75/92, p Conclusions Our data suggest that fluid restriction reduces intraoperative PRC transfusions without significantly increasing postoperative transfusions in cardiac surgery; this effect is more pronounced in transfusion-prone patients.

    Red blood cell (RBC) alloimmunization is a significant clinical complication of sickle cell disease (SCD). It can lead to difficulty with cross-matching for future transfusions and may sometimes trigger life-threatening delayed hemolytic transfusion reactions. We conducted a retrospective study to explore the association of clinical complications and age of RBC with alloimmunization in patients with SCD followed at a single institution from 2005 to 2012. One hundred and sixty six patients with a total of 488 RBC transfusions were evaluated. Nineteen patients (11%) developed new alloantibodies following blood transfusions during the period of review. The median age of RBC units was 20 days (interquartile range: 14–27 days). RBC antibody formation was significantly associated with the age of RBC units (P = 0.002), with a hazard ratio of 3.5 (95% CI: 1.71–7.11) for a RBC unit that was 7 days old and 9.8 (95% CI: 2.66–35.97) for a unit that was 35 days old, 28 days after the blood transfusion. No association was observed between RBC alloimmunization and acute vaso-occlusive complications. Although increased echocardiography-derived tricuspid regurgitant jet velocity (TRV) was associated with the presence of RBC alloantibodies (P = 0.02), TRV was not significantly associated with alloimmunization when adjusted for patient age and number of transfused RBC units. Our study suggests that RBC antibody formation is significantly associated with older age of RBCs at the time of transfusion. Prospective studies in patients with SCD are required to confirm this finding. PMID:25963831

    The major application of blood irradiation is for the prevention of graft-versus-host disease on immunodeficient patients by the abrogation of T-lymphocytes. Despite screening of blood donations, transfusion associated transmission of infections due to contaminated blood products is common. Hence, there is potential for the application of irradiation for the inactivation of pathogenic microbes in blood products. Literature on the effect of radiation on blood components is reviewed in order to make a rational decision on the feasibility of their irradiation

    As a result of human error, an estimated 1 in 12,000 blood transfusions is given to the wrong patient. The cause of nearly all of these errors is failure of hospital personnel to identify positively intended transfusion recipients, their blood samples for cross-matching, or their correct blood components. We describe our experience using a point-of-care bar code transfusion safety system that links patients' bar-coded wristbands, with bar-coded labels on blood sample tubes, blood component bags, and nurses' identification badges. The result was 100 % accuracy of matching patients, their blood samples, and components for transfusions. For verifying information before starting blood transfusions, nurses preferred bar code "double checks" to conventional visual "double checks" by a second nurse. Methods are needed to reinforce nurses' proficiency with technological approaches to transfusion safety, such as software-driven bar code scanning, in situations where transfusions are administered infrequently.

    Malaria inflicts humankind over centuries, and it remains as a major threat to both clinical medicine and public health worldwide. Though hemotherapy is a life-sustaining modality, it continues to be a possible source of disease transmission. Hence, hemovigilance is a matter of grave concern in the malaria-prone third-world countries. In order to pursue an effective research on hemovigilance, a comprehensive search has been conducted by using the premier academic-scientific databases, WHO documents, and English-language search engines. One hundred two appropriate articles were chosen for data extraction, with a particular reference to emerging pathogens transmitted through blood transfusion, specifically malaria. Blood donation screening is done through microscopic examination and immunological assays to improve the safety of blood products by detection major blood-borne pathogens, viz., HIV, HBV, HCV, syphilis, and malarial parasites. Transfusion therapy significantly dwindles the preventable morbidity and mortality attributed to various illnesses and diseases, particularly AIDS, tuberculosis, and malaria. Examination of thick and thin blood smears are performed to detect positivity and to identify the Plasmodium species, respectively. However, all of these existing diagnostic tools have their own limitations in terms of sensitivity, specificity, cost-effectiveness, and lack of resources and skilled personnel. Globally, despite the mandate need of screening blood and its components according to the blood-establishment protocols, it is seldom practiced in the low-income/poverty-stricken settings. In addition, each and every single phase of transfusion chain carries sizable inherent risks from donors to recipients. Interestingly, opportunities also lie ahead to enhance the safety of blood-supply chain and patients. It can be achieved through sustainable blood-management strategies like (1) appropriate usage of precise diagnostic tools/techniques, (2) promoting

  17. The Nlrp3 Inflammasome Does Not Regulate Alloimmunization to Transfused Red Blood Cells in Mice

    2016-07-01

    Full Text Available Red blood cell (RBC transfusions are essential for patients with hematological disorders and bone marrow failure syndromes. Despite ABO matching, RBC transfusions can lead to production of alloantibodies against “minor” blood group antigens. Non-ABO alloimmunization is a leading cause of transfusion-associated mortality in the U.S. Despite its clinical importance, little is known about the immunological factors that promote alloimmunization. Prior studies indicate that inflammatory conditions place patients at higher risk for alloimmunization. Additionally, co-exposure to pro-inflammatory pathogen associated molecular patterns (PAMPs promotes alloimmunization in animal models, suggesting that RBC alloimmunization depends on innate immune cell activation. However, the specific innate immune stimuli and sensors that induce a T cell-dependent alloantibody response to transfused RBCs have not been identified. The NLRP3 inflammasome senses chemically diverse PAMPs and damage associated molecular patterns (DAMPs, including extracellular ATP and iron-containing heme. We hypothesized that activation of the NLRP3 inflammasome by endogenous DAMPs from RBCs promotes the alloimmune response to a sterile RBC transfusion. Using genetically modified mice lacking either NLRP3 or multiple downstream inflammasome response elements, we ruled out a role for the NLRP3 inflammasome or any Caspase-1 or -11 dependent inflammasome in regulating RBC alloantibody production to a model antigen.

    Full Text Available Abstract Background Severe anaemia is a common cause for hospitalization in children in sub-Saharan Africa. Malaria plays an important aetiological role, resulting in a substantial burden of paediatric transfusion in hospitals. A decline in malaria and paediatric admissions to the Kilifi District Hospital has been reported recently. This study aimed to investigate whether this trend affected clinical burden, clinical severity of anaemia and requirements for paediatric transfusion. Methods Eight-year retrospective review of paediatric admissions to Kilifi District Hospital, Kenya describing the frequency of moderate and severe anaemia, blood transfusion and case fatality over time. Definitions for severe anaemia were Hb Results Of the 35,139 admissions 13,037 (37% had moderate anaemia and 2,265 (6% had severe anaemia; respiratory distress complicated 35% of cases with Hb 2 for trend = 134, P Conclusion The impact of reduced malaria transmission on child morbidity has positive public benefits on the demand and use of blood for paediatric transfusion. Despite an overall reduction in paediatric transfusion requirement, case fatality of severe anaemia remained unchanged over this decade. Further research is required to improve outcome from severe anaemia, particularly in the high-risk group with life threatening features.

  1. Effective RES blood flow changes in children with homozygous β-thalassemia in relation to blood transfusion

    International Nuclear Information System (INIS)

    Denatured radioiodinated human serum albumin (DHA) clearance studies at a dose of 1 mg/kg body wt., were carried out in 16 thalassemic children, prior to and 7-10 days following blood transfusion, to investigate changes of the effective RES blood flow which might accompany the posttransfusion spleen size diminution. A statistically significant increase (P<0.001) of the DHA plasma clearance rate was observed 7-10 days following blood transfusion denoting an increase of the blood flow to the effective RES while at the same time the spleen diminished in size. It is suggested that changes in the effective RES blood flow in these patients are directly related to changes in the intrasplenic circulatory capacity. (orig.)

The present study aimed to fill that gap and assess the value of ferritin in the diagnosis of iron overload and deficiency. Design. From January to February 2012, we prospectively studied 85 hemodialysis patients (78% of males and 22% of females aged 20 to 79 years attending the Gabonese National Hemodialysis Centre. Results. Correlation studies showed (a a strong positive linear relationship between the number of blood transfusions and high serum ferritin in hemodialysis patient (Spearman r:0.74; P value: 0.0001; (b a weak association between the number of blood transfusions and serum iron concentrations (Spearman r:0.32; P value: 0.04; (c a weak association between serum ferritin and serum iron (Spearman r:0.32; P value: 0.003. Also, the strength of agreement beyond chance between the levels of ferritin and iron in the serum was poor (κ=0.14. The prevalence of iron overload was 10.6%, whereas the prevalence of iron deficiency was 2.3%, comparing (1 patients with a maximum of one transfusion not on iron therapy; (2 patients with a maximum of one transfusion on iron therapy; (3 polytransfused patients not on iron therapy; and (4 polytransfused patients on oral iron therapy. The “Kruskal-Wallis test” showed that ferritin levels varied significantly between the groups (P value: 0.0001. Conclusion. Serum ferritin is not reliable as a marker of iron overload.

    Background: Confidential unit exclusion (CUE) system has been designed to enhance transfusion safety as an extra additive approach. Aims: This study was designed to survey demographic characteristics, prevalence of serologic markers, and reasons of opting CUE. Materials and Methods: The cross-sectional study was performed at Shiraz Blood Transfusion Center (Southern Iran). CUE is used for all individuals who refer for blood donation, and donors can choose their blood not to be used if they have any doubt about their blood suitability for transfusion. The prevalence rate of HIV, hepatitis B virus (HBV), and hepatitis C virus (HCV) was compared between the blood donors who opted into and out of CUE. Then, the donors were contacted to give another blood sample and the reasons of deferral. Researchers also determined whether their reasons were logical or not. Data were analyzed using comparison of proportions in MedCalc software 7. Results: Out of all the donors, 2365 ones (2.3%) opted for CUE. CUE was more frequent among men, singles, donors with low education levels, between 18 and 25 years old, and with history of previous donation (P 0.05). Furthermore, 91.5% of the donors had opted for CUE by mistake and only 8% had chosen CUE logically. Conclusion: It is necessary to review the process of CUE, make some changes both in procedure and design, and then survey its effectiveness in blood safety.

    Donor and recipient sample biobanks are a precious tool in hemovigilance studies as well as in epidemiological and biological research, in particular with regards to safety against blood-borne agents. This paper describes the main transfusion biobanks existing in France and gives their advantages and limits. The National blood donation biobank, organized for medicolegal reasons, preserves samples of each blood donation for a 5-year period. The biobank of the Blood and Organ Transmissible Infectious Agents (BOTIA) project stocks paired donor-recipient samples with a research objective. Preserved over a long period of time, such transfusion biobanks will be useful in terms of public health, as a reflection of the biological state of a population at a given moment. PMID:19442557

  8. Selection of Blood (Packed RBCs for Transfusion in Newborn Baby up to the Age of 4 Months

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available Proper selection of donor’s blood group is essential to prevent transfusion hazards. It is known that ABO antigen is fully developed at birth but the newborn baby does not produce ABO antibodies until 3 to 6 months of age. The ABO antibodies present in the serum of newborn babies are derived from mother’s blood due to placental transfer. So the blood group of the newborn baby is done by ABO antigen grouping (forward grouping only, antibody grouping (reverse grouping is not required. In case of transfusion of blood in newborn under 4 months of age, cross-matching of donor’s blood is done with the mother’s blood if it is available. We know, recipient’s same group of blood is always preferable in case of transfusion in adults or older children. But selection of blood for transfusion in the infants under 4 months of age depends on the mother’s blood group as well. If the mother’s blood group differs from the infant’s blood group, the infant’s same group of blood may not be selected for transfusion. For example, if the mother’s blood group is “O” and the newborn blood group is “A” or “B”, infant’s same group “A” or “B” group blood could not be transfused, because the anti-A & anti-B antibodies can be derived in the infant’s serum from mother’s blood which may react with the “A” or “B” antigen of the donor’s blood. In this case “O” group packed RBCs should be selected for transfusion. “O” group whole blood may contain IgG anti-A and anti-B antibodies in the plasma which can react with the “A” or “B” antigen of the infant’s blood. So to avoid anti-A & anti-B antibodies in “O” group, plasma should be discarded and the packed RBCs should be transfused.In case of Rh-negative mother with Rh positive baby, Rh antibody may develop in mother’s blood and Rh antibody may enter into baby’s circulation, in this case the infant should be transfused with Rh-negative blood to avoid Rh

    Mary A M Rogers

    Full Text Available OBJECTIVE: Randomized controlled trials demonstrated that red blood cell (RBC transfusion elevates the risk of infection, and trials are underway to evaluate whether RBC storage affects outcomes. We previously reported that transfusion predicts Clostridium difficile infection (CDI and, therefore, planned an investigation to examine this further using a more robust design. DESIGN: Within-person case-crossover study. Hospitalizations in which CDI developed (n = 406 were compared to hospitalizations for the same individuals in which CDI did not occur (n = 949. Transfusion volume and storage duration were assessed prior to the onset of CDI. SETTING: University of Michigan Health System. PATIENTS: Participants were individuals with a diagnosis of CDI from July 2009 through June 2012. MEASUREMENTS AND MAIN RESULTS: During the hospitalizations when CDI occurred, 34.7% of the patients received allogeneic RBC transfusions (mean volume, 688 ml compared to 19.0% of patients in hospitalizations without CDI (mean volume, 180 ml. The odds of healthcare-associated CDI increased by 76% (95% CI 1.39-2.23 for every liter of RBCs transfused and was elevated in both nonsurgical (OR = 1.90 and surgical (OR = 1.86 hospitalizations. In patients who received RBC transfusions, the odds of developing CDI increased by 6% for every additional day of RBC stored and by 53% for every week of additional storage (P = 0.002. CONCLUSIONS: Hospitalizations in which a patient received a greater volume of RBC transfusions were more likely to be associated with the development of CDI. RBC units stored for a longer duration were associated with the development of healthcare-associated CDI after adjustment for RBC volume.

    2014-10-01

    Full Text Available Background. We retrospectively investigated the incidence and risk factors for transfusion-related acute lung injury (TRALI among patients transfused for post-partum hemorrhage (PPH. Methods. We identified a series of 71 consecutive patients with PPH requiring the urgent transfusion of three or more red blood cell (RBC units, with or without fresh frozen plasma (FFP and platelet (PLT transfusion. Clinical records were then retrieved and examined for respiratory distress events. According to the 2004 consensus definition, cases of new-onset hypoxemia within 6 hours after transfusion, with bilateral pulmonary changes in the absence of cardiogenic pulmonary edema  were identified as TRALI; if an alternative risk factor for acute lung injury was present,  possible TRALI was diagnosed.Results. Thirteen cases of TRALI and 1 case of possible TRALI were identified (overall incidence 19.7%.  At univariate analysis, patients with TRALI received higher number of RBC, PLT and FFP units and had a longer post-partum hospitalization. Among several pregnancy-related diseases (including hypertensive disorders, anemia, intrahepatic cholestasis, gestational diabetes and various pre-existing comorbidities, only gestational hypertension and pre-eclampsia   significantly increased the risk to develop  TRALI (p = 0.006. At multivariate analysis, including both transfusion- and patient-related risk factors, pregnancy-related hypertensive disorders were confirmed to be the only predictors for TRALI, with an odds ratio of 27.7 ( 95% CI 1.27-604.3, p=0.034.Conclusions. Patients suffering from PPH represent a high-risk population for TRALI. In particular, patients with gestational hypertension and pre-eclampsia   have the highest risk, particularly if they are not receiving anti-hypertensive therapy. A careful monitoring of these patients after transfusions is therefore recommended.

    The influence of perioperative whole-blood transfusion and transfusion with erythrocyte suspension (SAG-M blood) on postoperative depression of cell-mediated immunity (CMI) was investigated in 67 patients who underwent elective resection for colorectal cancer. Cell-mediated immunity was assessed...... pre- and postoperatively by skin testing with seven common delayed-type hypersensitivity (DTH) antigens. The postoperative skin-test response decreased more in the patients who received whole blood (15 patients) than in those who received SAG-M blood (16 patients) (60% versus 42%, p less than 0.......001) and in those who did not receive a blood transfusion (36 patients) (60% versus 40%, p less than 0.001). The enhanced postoperative immunosuppression in patients who received whole-blood transfusions persisted after matching according to age, sex, height, weight, hemoglobin and serum albumin levels...

    Full Text Available Screening of blood and blood products is important to reduce the risk of transfusion transmitted infections (TTIs. The transfusion of unscreened or inadequately screened blood and blood products are the major source of TTIs. The aim of this paper is to find out the prevalence of TTIs in ABO blood groups and Rh type system. A total of 4128 blood donors were screened from January 2010 to April 2014. Serological tests were performed for hepatitis B surface antigen (HBsAg, anti hepatitis C virus (Anti-HCV, anti HIV-1 and 2, venereal disease research laboratory test (VDRL and malaria parasite (MP antigen. In seroreactive donors, HBsAg, Anti-HCV, VDRL, MP antigen and anti HIV were positive in 40 cases, 26 cases, 19 cases, 6 cases and 2 cases, respectively. Highest percentage of HBsAg, Anti HCV, VDRL, MP antigen and anti HIV was observed in blood group A negative (2/50, O negative (1/66, B negative (1/91, AB positive (2/377 blood group respectively. In the present study, the total number of Rh-negative donors is lower when compared to Rh-positive blood donors, but Rh-negative blood donors show higher percentages of seroreactivity for TTIs. Larger scale studies at molecular level are required to improve the knowledge of this aspect.

    Full Text Available INTRODUCTION: Transmission of infectious diseases through donated blood is of concern to blood safety as transfusion forms an integral part of medical and surgical therapy. Blood transfusion carries the risk of transfusion-transmissible infections including HIV, hepatitis etc. Screening of voluntary donors who represent healthy population serves as a predictor for these dreadful diseases in healthy population. MATERIALS AND METHODS: This retrospective study was conducted at the blood bank of MIMS, Mandya. Data were analyzed for a period of 5 years from Jan 2009 to Dec 2013. All voluntary donors reporting to the blood bank were screened for hepatitis B (HBV, Hepatitis C Virus (HCV, HIV by using ELISA. The Rapid plasma regain test (RPR test was used for estimation of syphilis infection. RESULTS: The most common infection was hepatitis B (1.2% followed by HIV infection (0.27% and HCV (0.09% in our study. CONCLUSION: This study has shown a decrease in seroprevalence of HIV and increase in seroprevalence of HCV over the 5 year study period.

    Although it is widely accepted that aspirin will increase the risk of intra- and post-operative bleeding, clinical studies have not consistently supported this assumption. We aimed to assess the effect of pre-operative aspirin on blood loss and transfusion requirements in patients undergoing emergency fixation of femoral neck fractures. A prospective case-control study was undertaken in patients presenting with femoral neck fractures. Parameters recorded included intra-operative blood loss, post-operative blood loss, transfusion requirements and peri-operative reduction in haemoglobin concentration. Of 89 patients presenting with femoral neck fractures 32 were on long-term aspirin therapy. Pre-operative aspirin ingestion did not significantly affect peri-operative blood loss, or change in haemoglobin concentration or haematocrit. However those patients taking aspirin pre-operatively had a significantly lower haemoglobin concentration and haematocrit and were more likely to be anaemic at presentation than those who were not receiving aspirin. Patients taking aspirin were also more likely to receive blood transfusion post-operatively.

    Full Text Available Objective:To analyze the relationship between hematimetric variation and the presence of clinical symptoms of hypoperfusion for indicating blood transfusion in patients undergoing total knee arthroplasty.Methods:A retrospective analysis was conducted on data gathered from the medical files of 55 patients with a diagnosis of gonarthrosis, who underwent total knee arthroplasty at a hospital orthopedics and traumatology service between February 2011 and December 2012. The patients studied presented unilateral joint degeneration and fitted into the indications for surgical treatment. All the patients underwent a preoperative cardiological evaluation, presenting a pattern of ASA I–III and absence of blood dyscrasia, and preoperative hemoglobin measurements were made. However, no minimum hematimetric value was established for the surgical treatment; there were only clinical criteria for blood perfusion.Results:Among the 55 patients, 35 were female and 20 were male, and the mean age was 68 years. Six patients underwent homologous blood transfusion, because of their clinical condition of tissue hypoperfusion, persistent hypotension, loss of consciousness, sweating and coercible vomiting. They presented postoperative hemoglobin of 7.5–8.8 g/dL.Conclusion:For patients with falls in hemoglobin counts greater than 20% and values lower than 9 g/dL after the surgery, there is a possible need for blood transfusion, which should only be indicated when accompanied by major symptoms of tissue hypoperfusion.

    We studied whether volunteers giving blood to the Greater New York Blood Program (GNYBP) cooperated with procedures implementing public health recommendations intended to decrease the risk of acquired immunodeficiency syndrome (AIDS) transmission by blood transfusion. Predonation medical screening was expanded to exclude donors who might be ill with AIDS. To exclude possible asymptomatic carriers of the disease, members of groups at increased risk of AIDS were asked either not to give blood or to give it for laboratory studies. A confidential questionnaire, administered to all donors after medical screening, provided the vehicle for donors to advise the GNYBP whether their donation was for laboratory studies or for patient transfusion. We found that the number of male donors decreased; AIDS-related questions in medical history led to a 2 percent increase in donor rejections; 97 percent of donors said their blood could be used for transfusions; 1.4 percent said their blood could be used for laboratory studies only; and 1.6 percent did not respond. Only units designated for transfusion were released to hospitals. People who indicated that their donation was for laboratory studies had a higher prevalence of markers for hepatitis B virus and of antibodies to cytomegalovirus. White cell counts and helper/suppressor T lymphocyte ratios were not significantly different in the two groups. We conclude that volunteer donors have cooperated with the established procedures. None of the laboratory assays identified blood units donated by individuals who, based on information about AIDS high-risk groups, designated their donation for laboratory studies. PMID:3969698

    This systematic review addresses the issue of wrong blood in tube (WBIT). The objective was to identify interventions that have been implemented and the effectiveness of these interventions to reduce WBIT incidence in red blood cell transfusion. Eligible articles were identified through a comprehensive search of The Cochrane Library, MEDLINE, EMBASE, Cinahl, BNID, and the Transfusion Evidence Library to April 2013. Initial search criteria were wide including primary intervention or observational studies, case reports, expert opinion, and guidelines. There was no restriction by study type, language, or status. Publications before 1995, reviews or reports of a secondary nature, studies of sampling errors outwith transfusion, and articles involving animals were excluded. The primary outcome was a reduction in errors. Study characteristics, outcomes measured, and methodological quality were extracted by 2 authors independently. The principal method of analysis was descriptive. A total of 12,703 references were initially identified. Preliminary secondary screening by 2 reviewers reduced articles for detailed screening to 128 articles. Eleven articles were eventually identified as eligible, resulting in 9 independent studies being included in the review. The overall finding was that all the identified interventions reduced WBIT incidence. Five studies measured the effect of a single intervention, for example, changes to blood sample labeling, weekly feedback, handwritten transfusion requests, and an electronic transfusion system. Four studies reported multiple interventions including education, second check of ID at sampling, and confirmatory sampling. It was not clear which intervention was the most effective. Sustainability of the effectiveness of interventions was also unclear. Targeted interventions, either single or multiple, can lead to a reduction in WBIT; but the sustainability of effectiveness is uncertain. Data on the pre- and postimplementation of

Escalating elective surgery, shortages arising from a fall in supply, a lack of national blood transfusion services, policies, appropriate infrastructure, trained personnel, and financial resources to support the running of a voluntary nonremunerated donor transfusion service, and old and emerging threats of transfusion-transmitted infection, have all conspired to ensure that allogenic blood remains very much a vital but limited asset to healthcare delivery particularly in Sub-Saharan Africa. This is further aggravated by the predominance of family replacement and commercially remunerated blood donors, rather than regular benevolent, nonremunerated donors who give blood out of altruism. The demand for blood transfusion is high in Sub-Saharan Africa because of the high prevalence of anemia especially due to malaria and pregnancy-related complications. All stakeholders in blood transfusion have a significant challenge to apply the best available evidenced-based medical practices to the world-class management of this precious product in a bid to using blood more appropriately. Physicians in Sub-Saharan Africa must always keep in mind that the first and foremost strategy to avoid transfusion of allogenic blood is their thorough understanding of the pathophysiologic mechanisms involved in anemia and coagulopathy, and their thoughtful adherence to the evidenced-based good practices used in the developed world in a bid to potentially reduce the likelihood of allogenic blood transfusion in many patient groups. There is an urgent need to develop innovative ways to recruit and retain

    The primary mission of the European Blood Alliance (EBA) is to contribute to the safety and efficiency of the supply of blood products, cells and tissues, in developing an active network of blood establishments in Europe (25 countries). Its strategic objectives are to improve performance (through working groups and projects funded by the European Union), to engage in regulatory affairs (particularly at the European Commission level) to promote best practices and to facilitate a network to collect and share knowledge and experiences. The main objective of EuroNet TMS, combining the blood scientific societies from more than 30 countries in Europe, is to update and publish regularly, intended for policymakers, a White Book on the transfusion chain from donor to patient and probable or possible changes in the coming 5 years. Since 2008, EBA and EuroNet TMS actively collaborate on the drafting of the 2nd edition to be published in 2011. The two presidents jointly drafted the final chapter outlining the major issues of transfusion for tomorrow, summarized thereafter. Transfusion will still be useful for a long time and for reasons of safety and ethics the voluntary and unpaid donations, with non-profit blood establishments, will remain, the cornerstone of the supply of blood products. This renders crucial the continuous improvement of donor management and optimal blood use. On the regulatory side, after 5 years of implementation, EU directives must be independently evaluated and the Blood Guide of the Council of Europe should gradually become a regulatory standard. Finally, if a competition should be introduced for the blood products, it should be strictly regulated to prevent any threat to the security of their supply and quality for patients. PMID:21458349

    The Retrovirus Epidemiology Donor Study (REDS) program was established in the United States in 1989 with the purpose of increasing blood transfusion safety in the context of the HIV/AIDS and human T-lymphotropic virus epidemics. REDS and its successor, REDS-II were at first conducted in the US, then expanded in 2006 to include international partnerships with Brazil and China. In 2011, a third wave of REDS renamed the Recipient Epidemiology and Donor Evaluation Study-III (REDS-III) was launched. This seven-year research program focuses on both blood banking and transfusion medicine research in the United States of America, Brazil, China, and South Africa. The main goal of the international programs is to reduce and prevent the transmission of HIV/AIDS and other known and emerging infectious agents through transfusion, and to address research questions aimed at understanding global issues related to the availability of safe blood. This article describes the contribution of REDS-II to transfusion safety in Brazil. Articles published from 2010 to 2013 are summarized, including database analyses to characterize blood donors, deferral rates, and prevalence, incidence and residual risk of the main blood-borne infections. Specific studies were developed to understand donor motivation, the impact of the deferral questions, risk factors and molecular surveillance among HIV-positive donors, and the natural history of Chagas disease. The purpose of this review is to disseminate the acquired knowledge and briefly summarize the findings of the REDS-II studies conducted in Brazil as well as to introduce the scope of the REDS-III program that is now in progress and will continue through 2018.

    2016-06-01

    Here, we present a case of a deceased-donor kidney transplant. The brain-dead donor had received a massive blood transfusion during cardiopulmonary bypass, which lead to hemolysis, hemoglobinuria, acute kidney injury, and renal replacement therapy. The kidney appeared red after in situ flush. Postoperatively, the recipient developed delayed graft function. Protocol biopsy during the postoperative period revealed the widespread deposition of heme pigment in the renal tubules. Massive blood transfusion and cardiopulmonary bypass surgery are associated with hemolysis and heme pigment deposition in the renal tubules, which subsequently lead to acute kidney injury. Kidneys from such donors appear red and, while this does not preclude transplant, are likely to develop delayed graft function. PMID:26030717

    Full Text Available Free hemoglobin (fHb may induce vasoconstriction by scavenging nitric oxide. It may increase in older blood units due to storage lesions. This study evaluated whether old red blood cell transfusion increases plasma fHb in sepsis and how the microvascular response may be affected.This is a secondary analysis of a randomized study. Twenty adult septic patients received either fresh or old (15 days storage, respectively RBC transfusions. fHb was measured in RBC units and in the plasma before and 1 hour after transfusion. Simultaneously, the sublingual microcirculation was assessed with sidestream-dark field imaging. The perfused boundary region was calculated as an index of glycocalyx damage. Tissue oxygen saturation (StO2 and Hb index (THI were measured with near-infrared spectroscopy and a vascular occlusion test was performed.Similar fHb levels were found in the supernatant of fresh and old RBC units. Despite this, plasma fHb increased in the old RBC group after transfusion (from 0.125 [0.098-0.219] mg/mL to 0.238 [0.163-0.369] mg/mL, p = 0.006. The sublingual microcirculation was unaltered in both groups, while THI increased. The change in plasma fHb was inversely correlated with the changes in total vessel density (r = -0.57 [95% confidence interval -0.82, -0.16], p = 0.008, De Backer score (r = -0.63 [95% confidence interval -0.84, -0.25], p = 0.003 and THI (r = -0.72 [95% confidence interval -0.88, -0.39], p = 0.0003.Old RBC transfusion was associated with an increase in plasma fHb in septic patients. Increasing plasma fHb levels were associated with decreased microvascular density.ClinicalTrials.gov NCT01584999.

    2014-01-01

    To conserve D- red blood cells (RBCs), our facility developed a policy for transfusion of D+ units to D- patients, particularly in trauma situations. To our knowledge, this is the first study looking at D-mismatched RBC transfusion in trauma patients. We developed guidelines for the transfusion of D-mismatched RBCs. patients were followed by anti body screening and direct antiglobulin testing. Twenty-six patients were identified, and 57.7 percent of the cases were the result of trauma. Follow-up ranged from 7 to 455 days. The trauma cohort had a follow-up of 7 to 102 days. Overall, patients were transfused with 1 to 36 units of D-mismatched RBCs. Three patients produced alloanti-D, resulting in a 20 percent rate of antibody formation rate of 11.5 percent compared with 21.4 to 30.4 percent in previous studies. Approximately 58 percent of our study population was composed of trauma patients. Within that cohort, the formation of anti-D was 20 percent, similar to the rate seen in previous studies looking at primarily non-trauma populations. PMID:25831260

    2015-11-01

    There has been much debate and controversy about the safety and efficacy of the topical use of tranexamic acid in primary total knee arthroplasty (TKA). The purpose of this study was to perform a meta-analysis to evaluate whether there is less blood loss and lower rates of transfusion after topical tranexamic acid administration in primary TKA. A systematic review of the electronic databases PubMed, CENTRAL, Web of Science, and Embase was undertaken. All randomized, controlled trials and prospective cohort studies evaluating the effectiveness of topical tranexamic acid during primary TKA were included. The focus of the analysis was on the outcomes of blood loss results, transfusion rate, and thromboembolic complications. Subgroup analysis was performed when possible. Of 387 studies identified, 16 comprising 1421 patients (1481 knees) were eligible for data extraction and meta-analysis. This study indicated that when compared with the control group, topical application of tranexamic acid significantly reduced total drain output (mean difference, -227.20; 95% confidence interval, -347.11 to -107.30; Pdeep venous thrombosis or pulmonary embolism due to tranexamic acid administration. Topical tranexamic acid was effective for reducing postoperative blood loss and transfusion requirements without increasing the prevalence of thromboembolic complications. PMID:26558665

    Full Text Available Objective  To study the characteristic of HIV-1 gene mutation in HIV/AIDS patients infected by blood transfusion, and analyze the resistance to anti-HIV drugs. Methods  Plasma samples were collected from 37 HIV/AIDS patients infected by blood transfusion for extraction of HIV-1 RNA. The gene fragments of HIV pol domain were amplified by RT-PCR and nested-PCR , and the electrophoresis positive products were sequenced. The sequencing result was landed to the website http:// HIV-1db.stanford.edu to analyze the drug resistance mutations. Results  Drug resistance mutations were found in 20 patients, including 19 cases of virological or immunological failure. Mutation of gene locus V32AV of protease inhibitors (PIs occurred in 3 patients during the treatment, but it did not cause the drug resistance of PIs. Mutation of the coding regions of reverse transcriptase was found in 23 patients, including M184V, TAMs, Q151M complexus, K103N, Y181C and so on. Of the 23 patients mentioned above, the HIV-1 gene mutation induced the resistance to reverse transcriptase inhibitors (RTIs in 20 patients, and the mutation rate of RTIs was 54.05% (20/37. Conclusion  The drug resistance rate of HIV-1 in patients infected by blood transfusion may be high for antiviral therapy, so the drug resistance of HIV-1 should be monitored and treatment plan should be adjusted timely.

    Full Text Available Backdround: Emerging infectious diseases pose threats to the general human population; including recipients of blood transfusions. Dengue is spreading rapidly to new areas and with increasing frequency of major outbreaks. Screening blood for dengue antigens in dengue-endemic countries would be costly and should, therefore, be recommended only after careful assessment of risk for infection and cost. Aim: A prospective study was conducted to establish the magnitude of the threat that dengue poses to blood safety where it is sporadic with seasonal variations, to quantify risk and to assess that whether screening is feasible and cost-effective. Materials and Methods: Nonstructural protein 1 (NS1 antigen test was done on 1709 donations during dengue outbreak in the months August to November 2013 as an additional test using Bio-Rad Platelia Dengue NS1AG test kit which is one step sandwich format microplate enzyme immunoassay using murine monoclonal antibodies for capture and revelation. Chi-square test was used to find statistical significance. Results and Conclusions: Majority cases were whole blood, replacement, male donors with 76.10% donors in <35 years age group. About 17.85% were single donor platelet donations. NS1 antigen in all donors was negative. In the past, dengue affected mainly children who do not donate blood. With the changing trend, mean age of infection increased affecting the population that does donate blood, further reducing blood donation pool. Further studies need to be done in different geographic regions of the country during dengue transmission season to establish maximum incidence of viremic donations, rates of transfusion transmission and clinical consequences in recipients. If risk is found to be substantial, decision will be taken by the policymakers at what threshold screening should be instituted to ensure safe blood transfusion.

    Full Text Available Blood product transfusions are associated with increased morbidity and mortality. The purpose of this study was to determine if implementation of a restrictive protocol for packed red blood cell (PRBC and fresh frozen plasma (FFP transfusion safely reduces blood product utilization and costs in a surgical intensive care unit (SICU.We performed a retrospective, historical control analysis comparing before (PRE and after (POST implementation of a restrictive PRBC/FFP transfusion protocol for SICU patients. Univariate analysis was utilized to compare patient demographics and blood product transfusion totals between the PRE and POST cohorts. Multivariate logistic regression models were developed to determine if implementation of the restrictive transfusion protocol is an independent predictor of adverse outcomes after controlling for age, illness severity, and total blood products received.829 total patients were included in the analysis (PRE, n=372; POST, n=457. Despite higher mean age (56 vs. 52 years, p=0.01 and APACHE II scores (12.5 vs. 11.2, p=0.006, mean units transfused per patient were lower for both packed red blood cells (0.7 vs. 1.2, p=0.03 and fresh frozen plasma (0.3 vs. 1.2, p=0.007 in the POST compared to the PRE cohort, respectively. There was no difference in inpatient mortality between the PRE and POST cohorts (7.5% vs. 9.2%, p=0.39. There was a decreased risk of urinary tract infections (OR 0.47, 95%CI 0.28-0.80 in the POST cohort after controlling for age, illness severity and amount of blood products transfused.Implementation of a restrictive transfusion protocol can effectively reduce blood product utilization in critically ill surgical patients with no increase in morbidity or mortality.

    Full Text Available Objective:To evaluate blood banks in the Brazilian Amazon region with regard to structure and procedures directed toward the prevention of transfusion-transmitted malaria (TTM.Methods:This was a normative evaluation based on the Brazilian National Health Surveillance Agency (ANVISA Resolution RDC No. 153/2004. Ten blood banks were included in the study and classified as 'adequate' (≥80 points, 'partially adequate' (from 50 to 80 points, or 'inadequate' (<50 points. The following components were evaluated: 'donor education' (5 points, 'clinical screening' (40 points, 'laboratory screening' (40 points and 'hemovigilance' (15 points.Results:The overall median score was 49.8 (minimum = 16; maximum = 78. Five blood banks were classified as 'inadequate' and five as 'partially adequate'. The median clinical screening score was 26 (minimum = 16; maximum = 32. The median laboratory screening score was 20 (minimum = 0; maximum = 32. Eight blood banks performed laboratory tests for malaria; six tested all donations. Seven used thick smears, but only one performed this procedure in accordance with Ministry of Health requirements. One service had a Program of External Quality Evaluation for malaria testing. With regard to hemovigilance, two institutions reported having procedures to detect cases of transfusion-transmitted malaria.Conclusion:Malaria is neglected as a blood–borne disease in the blood banks of the Brazilian Amazon region. None of the institutions were classified as 'adequate' in the overall classification or with regard to clinical screening and laboratory screening. Blood bank professionals, the Ministry of Health and Health Surveillance service managers need to pay more attention to this matter so that the safety procedures required by law are complied with.

    2007-11-01

    As part of a quality assurance process in the transfusion service of a hospital blood bank of Yaoundé, Cameroon, a selection of units of red cell concentrates (RCC) were evaluated for volume, haemoglobin, and haematocrit levels as well as blood cell content. Blood samples were all collected into standard double blood bags containing an anticoagulant, citrate-phosphate-dextrose and adenine. During a three-month period, 35 bags intended for the preparation of the RCC were analysed. After relevant screening for transfusion transmissible infections ,and ABO and rhesus (RH1) blood grouping, the bags were centrifuged to obtain RCC. The resultant red cell bags were weighed and the volumes estimated. Full blood counts were performed on samples of the RCC using an electronic particle counter (DIANA 5, HYCEL Diagnostics, Reims, France). The results obtained showed that, based on ISO 9001: 2000 norms, there were 57, 66 and 80% of RCC respectively with volumes, hemoglobin levels as well as hematocrit that were in conformity with the norms. When the data was analysed based on the Algerian norms, 83, 66 and 95% respectively conformed. The significance of these findings and the need for establishing local norms for quality assurance in our community are discussed. PMID:18295526

    Since November 2015, Puerto Rico has reported active mosquito-borne transmission of Zika virus (1). Because of the potential for Zika virus to be transmitted through transfusion of blood components, and because a high percentage of persons infected with Zika virus are asymptomatic (2), the Food and Drug Administration (FDA) recommended that blood collections cease in areas of the United States affected by active vector-borne transmission of Zika virus until laboratory screening of blood donations or pathogen reduction technology (PRT)* for treatment of blood components can be implemented (3). To inform efforts to maintain the safety and availability of the blood supply in Puerto Rico, CDC, in collaboration with the Puerto Rico Department of Health, conducted a rapid assessment of blood collection and use on the island. A total of 139,369 allogeneic red blood cell (RBC) units,(†) 45,243 platelet units, and 56,466 plasma units were collected in or imported to Puerto Rico during 2015, and 135,966 allogeneic RBC units, 13,526 therapeutic platelet units,(§) and 25,775 plasma units were transfused. Because of the potential for local Zika virus transmission in areas with a competent mosquito vector (4), other areas of the United States should develop plans to ensure local blood safety and adequacy. Blood collection organizations and public health agencies should collaborate to maintain the safety and availability of local blood supplies in accordance with FDA guidance. PMID:27078190

    Blood component transfusion is an important and lifesaving Emergency Department (ED) procedure. It is not however risk-free and careful consideration of its clinical benefit for each individual patient is therefore essential. In 2008, we audited the patterns of blood component usage in 2007 within our ED. This work revealed that whilst 3209 units of blood component were ordered only 39.5% were transfused, and 9.5% were unaccounted for. This was the first and only published detailed look at ED blood transfusion practices. We had to address our poor traceability (i.e. unaccounted for units), our high blood usage, and our ordering of units which were then not transfused as this can lead to wastage. Firstly, better links between the ED and the Scottish National Blood Transfusion Service (SNBTS) were established. A set of improvement measures were then implemented including better ED medical and nursing staff education, monthly traceability reports sent to the ED clinical management teams, the introduction of an ED transfusion guideline, moving our blood fridge into the resuscitation room, having a named ED transfusion consultant and ED transfusion link nurse, ED consultant representation on the Hospital Transfusion Group and finally increasing awareness of ED emergency transfusion with a rotational thromboelastometry (ROTEM) research programme. In 2012, we re-audited our practice looking at our blood component usage in 2011. There was a 64% reduction in blood component ordering (3209 vs. 1034 units), a 39% reduction in blood component transfusion (1131 vs. 687 units), a 68% increase in the proportion of ordered units that were transfused and a 96% reduction in unaccounted units (289 vs. 9 units) between 2007 and 2011. In attempting to cost the savings resulting from our changes we showed that SNBTS spent £306,437 less in 2011 compared to 2007 on handling and issuing ED transfusion requests. Our improvements are immediately generalizable across the UK and the potential

    Full Text Available Background: Transfusion of blood remains the gold standard for fluid resuscitation from hemorrhagic shock. Hemoglobin (Hb within the red blood cell transports oxygen and modulates nitric oxide (NO through NO scavenging and nitrite reductase. Aims: This study was designed to examine the effects of incorporating a novel NO modulator, RRx-001, on systemic and microvascular hemodynamic response after blood transfusion for resuscitation from hemorrhagic shock in a hamster window chamber model. In addition, to RRx-001 the role of low dose of nitrite (1 × 10−9 moles per animal supplementation after resuscitation was studied. Materials and Methods: Severe hemorrhage was induced by arterial controlled bleeding of 50% of the blood volume (BV and the hypovolemic state was maintained for 1 h. The animals received volume resuscitation by an infusion of 25% of BV using fresh blood alone or with added nitrite, or fresh blood treated with RRx-001 (140 mg/kg or RRx-001 (140 mg/kg with added nitrite. Systemic and microvascular hemodynamics were followed at baseline and at different time points during the entire study. Tissue apoptosis and necrosis were measured 8 h after resuscitation to correlate hemodynamic changes with tissue viability. Results: Compared to resuscitation with blood alone, blood treated with RRx-001 decreased vascular resistance, increased blood flow and functional capillary density immediately after resuscitation and preserved tissue viability. Furthermore, in RRx-001 treated animals, both mean arterial pressure (MAP and met Hb were maintained within normal levels after resuscitation (MAP >90 mmHg and metHb <2%. The addition of nitrite to RRx-001 did not significantly improve the effects of RRx-001, as it increased methemoglobinemia and lower MAP. Conclusion: RRx-001 alone enhanced perfusion and reduced tissue damage as compared to blood; it may serve as an adjunct therapy to the current gold standard treatment for resuscitation from

  14. Tattoos and transfusion-transmitted disease risk: implications for the screening of blood donors in Brazil

    Directory of Open Access Journals (Sweden)

    Sérgio de A. Nishioka

    2002-08-01

    Full Text Available Having a tattoo has been associated with serological evidence of hepatitis B and C viruses, as well as human immunodeficiency virus infections and syphilis; all of these are known to be transmissible by blood transfusion. These associations are of higher magnitude for individuals with nonprofessionally-applied tattoos and with two or more tattoos. Tattoos are common among drug addicts and prisoners, conditions that are also associated with transfusion-transmitted diseases. We examined the implications of these associations for the screening of blood donors in Brazil. Numbers of individuals who would be correctly or unnecessarily deferred from blood donation on the basis of the presence of tattoos, and on their number and type, were calculated for different prevalence situations based on published odds ratios. If having a tattoo was made a deferral criterion, cost savings (due to a reduced need for laboratory testing and subsequent follow-up would accrue at the expense of the deferral of appropriate donors. Restricting deferral to more `at-risk' sub-groups of tattooed individuals would correctly defer less individuals and would also reduce the numbers of potential donors unnecessarily deferred. Key factors in balancing cost savings and unnecessary deferrals include the magnitude of the pool of blood donors in the population, the prevalence of individuals with tattoos and the `culture' of tattoos in the population. Tattoos can therefore be an efficient criterion for the screening of blood donors in certain settings, a finding that requires corroboration from larger population-based studies.

    Full Text Available Aim: To compare exchange transfusions done for severe malaria using the traditional whole blood exchange method with therapeutic red cell exchange (TREX done using a Cobe spectra cell separator. Methods: 6 children with acute, severe malaria and parasitic infestation rates (IR >50% with multi organ failure, were subjected to exchange transfusions. 3 had whole blood single volume exchanges and 3 had TREX using the Cobe-Spectra cell separator. The two groups were compared for difficulties encountered, time taken, complications, quantity of blood products used, metabolic and hematological derangements and fall in IR. Results: The TREX took less time per 100 ml of blood exchanged, resulted in a 24% more efficient decrease in the IR and required less donor plasma. 3/3 tolerated the TREX well whereas one child had complications of hypocalcemia and acidosis with the whole blood exchange. The rise in hemoglobin/hematocrit was comparable in both and the platelet count was not significantly altered in either group. There was no significant alteration in the DIC profile in either group. All 6 children recovered within comparable time frames. Conclusion: The TREX was safer, more efficacious and less time consuming. This procedure is recommended whenever available for red cell exchange in malaria.

    Full Text Available Background: In spite of many improvements that have reduced the blood component requirements, substantial numbers of transfusions are still needed in liver transplantation. Aims: The objective of the present study was to analyze the perioperative usage of allogenic blood components and predict the preoperative factors as predictors of red cell transfusion in live-related donor liver transplant recipients. Materials and Methods: The retrospective data on utilization of allogenic blood components were analyzed for a total of 150 liver transplant procedures. The data on utilization of blood components during surgery and till 48 hours of ICU stay was collected from the blood bank record and hospital information system (HIS. Results: Red cell concentrate was commonest blood component used in liver transplant recipient and most of the transfusion took place during surgery. During intraoperative period 92.7% (N = 139 of the cases utilized red cell components with the median number of five whereas in postoperative period only 38% (N = 57 of patients received blood with the median number of one. This study demonstrates that the preoperative hemoglobin and platelet count are the predictors of utilization of red cell concentrates during surgery. There were a total of 11 (7.3% recipients who didn′t receive allogeneic blood transfusion in any form.Utilization of blood components was negligible among organ donors. Conclusion: Our study demonstrates the pattern and predictors of usage of allogeneic blood components in liver transplant recipients at a tertiary healthcare center in India.

    Full Text Available Amy E Schmidt, Majed A Refaai, Scott A Kirkley, Neil Blumberg Department of Pathology and Laboratory Medicine, University of Rochester Medical Center, Rochester, NY, USA Abstract: Red blood cells (RBCs are washed for a variety of reasons such as to remove excess potassium, cytokines, and other allergen proteins from the supernatant and/or to mitigate the effects of the storage lesion. The storage lesion is a product of RBC aging and include leakage of potassium and chloride from the RBCs, depletion of 2,3-diphosphoglycerate and adenosine triphosphate, loss of phospholipids and cholesterol, exposure of phosphatidylserine, elaboration of lipid mediators, loss of glutathione, autoxidation of hemoglobin to methemoglobin contributing to decreased blood flow viscosity and adherence to endothelial cells, increased microparticle formation, and disruption of NO-mediated vasodilation. A storage lesion is thought to be caused in part by oxidative stress, which is characterized by functional and structural changes to the RBCs. The effects of the RBC storage lesion on patient morbidity and mortality have been studied intensively with mixed results. Here, we will summarize the potential benefits of RBC washing. Notably, all patient-based studies on washed RBCs are single-center, small randomized studies or observational data, which await replication and tests of generalizability. Some of the most promising preliminary data suggest that washed transfusions of red cells and platelets reduce mortality in low risk, younger patients with acute myeloid leukemia, mitigate lung injury, and substantially reduce mortality in cardiac surgery. Larger randomized trials to replicate or refute these findings are urgently needed and, most importantly, have the potential to strikingly improve clinical outcomes following transfusion.

    1992-03-01

    We report a case of a 70-yr-old white woman who underwent a revision of a total hip arthroplasty under general anaesthesia. The intraoperative course was stable without any complications and the estimated blood loss was 2500 ml. The patient received an autologous transfusion of blood from a wound drainage system in the recovery room. The transfusion was followed immediately by marked respiratory distress and upper airway oedema. She required emergency tracheal intubation and mechanical pulmonary ventilation. A coagulopathy also developed which was treated and resolved within 12 hr of the capillary leak phenomenon. The trachea was extubated on the first postoperative day and she had an uneventful course until discharge from the hospital two days later. We discuss the possible, aetiology of such a reaction to autologous blood including complement and platelet activation. It is suggested that reinfusion of nonwashed shed blood from a wound drainage system may present a hazard even though the fluid was autologous in origin. PMID:1551163

    In times of shrinking donor population, the recruitment of donors is of utmost importance. Recruitment can be done by personal communication, advertisement/information, classical mass media (newspaper, radio, TV) or new computerized media. The aim of this study was to gain information about the donors' demands of an Internet presentation of a blood transfusion service. Between October and December 2004 inclusive, prospective donors were asked to complete a survey about the impact of Internet information for blood donors. The survey contained questions measuring demographics, education and motivation for blood donation. In addition, the survey included questions that measured Internet access, duration of online time and donors' demands for an Internet presentation of a blood transfusion service. Donors were asked to tick a box with predefined answers. In cases where no options were applied, donors were requested to specify their answers. One hundred and fourteen prospective donors (71 female, 43 male) with a median age of 25 years (range 18-57 years) completed the survey. Most donors (57.9%) were 18-30 years old. Forty-two (36.8%) of the surveyed donors were repeat donors, whereas 72 (63.2%) were first-time donors. The majority of donors were informed about blood donation from relatives or friends (70.7% repeat donors and 67.7% first-time donors). Most of them had Internet access (85.7% repeat donors and 90.3% first-time donors). Exclusive use of private access was more often reported in repeat donors (77.8%), whereas both private and professional access was more frequently used in first-time donors (32.3%). Most donors used the Internet access daily, followed by weekly and monthly use. Multiple answers were given about the importance of desired information about the topic 'blood donation'. Both first-time and repeat donors wanted to be informed about organizational details of blood donation such as opening times, eligibility criteria, donation process and the kind

    2014-01-01

    Full Text Available Background: Many modern surgical procedures could not be carried out without the use of blood. There are no substitutes for human blood. Thus, proper utilization of blood is necessary with minimal wasting. Materials and Methods: A total of 10,582 donors donated blood during the study period of 19 months in blood bank of a tertiary care hospital, central India from 1 st of November 2009 to 31 st May 2011, which were screened. Results: A total of 346 whole blood bags were discarded. Out of these 346 blood bags, 257 (74.30% were discarded because of seropositivity for transfusion transmissible infectious diseases. A total of 542 blood components were discarded against 3702 blood components prepared during the study period. Among blood components discarded, most common units were platelets. The most common cause of discarding the blood components was expiry of date due to non-utilization (87.00%. Conclusion: A properly conducted donor interview, notification of permanently deferred donors will help in discarding less number of bags from collected units. Similarly, properly implemented blood transfusion policies will also help in discarding less number of blood bags due to expiry. These discarded bags, because they are unutilized are both financially as well as socially harmful to the blood bank.

    Full Text Available Anemia has an important role in exercise performance. However, the direct link between rapid changes of hemoglobin and exercise performance is still unknown.To find out more on this topic, we studied 18 beta-thalassemia major patients free of relevant cardiac dysfunction (age 33.5±7.2 years,males = 10. Patients performed a maximal cardiopulmolmonary exercise test (cycloergometer, personalized ramp protocol, breath-by-breath measurements of expired gases before and the day after blood transfusion (500 cc of red cell concentrates. After blood transfusion, hemoglobin increased from 10.5±0.8 g/dL to 12.1±1.2 (p<0.001, peak VO2 from 1408 to 1546mL/min (p<0.05, and VO2 at anaerobic threshold from 965 to 1024mL/min (p<0.05. No major changes were observed as regards heart and respiratory rates either at peak exercise or at anaerobic threshold. Similarly, no relevant changes were observed in ventilation efficiency, as evaluated by the ventilation vs. carbon dioxide production relationship, or in O2 delivery to the periphery as analyzed by the VO2 vs. workload relationship. The relationship between hemoglobin and VO2 changes showed, for each g/dL of hemoglobin increase, a VO2 increase = 82.5 mL/min and 35 mL/min, at peak exercise and at anaerobic threshold, respectively. In beta-thalassemia major patients, an acute albeit partial anemia correction by blood transfusion determinates a relevant increase of exercise performance, observed both at peak exercise and at anaerobic threshold.

    Full Text Available Seroprevalence of transfusion transmissible infections (TTIs among blood donors can be used to monitor the prevalence among apparently healthy adult population. The present study was conducted to determine the profile of blood donors and seroprevalence of TTI among them. Retrospective analysis of the donors of a blood bank attached with a tertiary care hospital of Kolkata in 2011 was carried out. Data were analyzed with SPSS version 17. Majority (85% of the donors were male, two-third in the age group of 21-40 years. Among the donors 2.79% were positive for any of the screened TTIs. Seroprevalence was highest for hepatitis B (1.41% followed by human immunodeficiency virus (0.60% and hepatitis C (0.59% and least for syphilis (0.23%. Seropositivity increased with age up to 50 years. There was no significant difference in seropositivity between male and female. Highly sensitive donor screening and public awareness program can make transfusion of blood products safe.

    In India transmission of transfusion transmissible infections (TTI) has shown a relative decrease as a result of mandatory screening of donated blood for TTI's. However, reducing the incidence of non infectious complications poses a major challenge, mainly due to the fact that a number of adverse reactions go unreported. Blood transfusion reaction, can be categorized based on the time interval between transfusion of blood products and the presentation of adverse reactions as acute i.e. those presenting during or within 24 h and as delayed i.e. those presenting anytime after 24 h. Transfusion reactions can further be classified as immune and non immune or infectious and non infectious based on the pathophysiology. In this retrospective study which was undertaken with an aim to determine the type and frequency of non infectious complications due to transfusion of blood and blood products recorded the incidence of febrile non hemolytic transfusion reactions (FNHTR) 51.40 %, allergic reactions 40.14 %, non immune hemolytic reactions 4.22 %, hypothermia 2.81 %, anaphylaxis 0.70 % and iron overload 0.70 %. FNHTR which was found to be the most common complication in this study can certainly be minimized, if not completely eliminated by adopting a policy of universal leucodepletion, the implementation of which solely depends on the financial and infrastructure resources available. This study also reiterates the importance of hemovigilance as a tool to improve the safety of blood transfusion. PMID:27429521

    Full Text Available Abstract We describe an unusual case of osteosarcoma in a Jehovah's Witness patient who underwent chemotherapy and major surgery without the need for blood transfusion. This 16-year-old girl presented with osteosarcoma of the right proximal tibia requiring proximal tibia resection, followed by endoprosthesis replacement. She was successfully treated with neoadjuvant chemotherapy and surgery with the support of haematinics, granulocyte colony-stimulating factor, recombinant erythropoietin and intraoperative normovolaemic haemodilution. This case illustrates the importance of maintaining effective, open communication and exploring acceptable therapeutic alternative in the management of these patients, whilst still respecting their beliefs.

    Children with sickle cell disease have a very high risk of lifelong neurologic morbidity and mortality. Cerebrovascular accidents are a known complication in children with sickle cell disease. Posterior reversible encephalopathy syndrome is a constellation of acute neurologic findings increasingly recognized in pediatric critical care population with evidence of vasogenic edema on brain imaging possibly due to cerebral vascular endothelial cell dysfunction. This report, for the first time, describes a young adult with sickle cell disease who developed posterior reversible encephalopathy syndrome following blood transfusion. PMID:22899796

    BACKGROUND: The true incidence of transfusion-associated hepatitis (TAH) before blood screening is unknown. Our aims were to reevaluate blood recipients receiving unscreened blood and analyze hepatitis viruses circulating more than 45 years ago. STUDY DESIGN AND METHODS: Cryopreserved serum samples......%) developed biochemical evidence of hepatitis; of these, 20 (67%) were infected with hepatitis C virus (HCV) alone, four (13%) with hepatitis B virus (HBV) alone, and six (20%) with both viruses. Among the 36 patients who did not develop hepatitis, four (11%) were newly infected with HCV alone, nine (25......%) with HBV alone, and one (3%) with both viruses. Overall, 100% of patients with hepatitis and 39% of those without hepatitis were infected with HBV and/or HCV; one patient was also infected with hepatitis E virus. The donor carrier rate for HBV and/or HCV was estimated to be more than 6%; contemporaneously...

    Blood Transfusion Services are striving to continually improve the efficacy and quality of their blood products whilst also simultaneously diversifying into novel cellular products. For this to be successful the relationships between the various arms of the organisation must be strong and interlinked. As new technologies impact on the products that blood transfusion services supply it should be noted that the interaction between the service and its donor base is also affected by advancing technologies. Social media has fundamentally altered the way in which the public can access information and news, as such blood services must engage and interact appropriately with these new forms of media. As a reflection of these challenges the Scotblood 2015 programme was focussed on service and product improvement, donor engagement and people centred transfusion. This commentary comprises summaries of the presentations, based in part on the abstracts provided by the speakers. PMID:27524267

    By the optimised availability of less expensive and safe red cell packs and other blood products over the last 20 years, numerous surgical interventions have become possible without any demand for comments on the precise need. However, a number of publications indicates that blood transfusion may also induce disadvantageous effects on the postoperative course by immunomodulation, which requires a rather restrictive indication for transfusion. Furthermore, demographic development leads to a decrease in that portion of the population with the potential for blood donation accompanied simultaneously by an increase of the percentage of older patients with more need of blood products during medical treatment. This makes blood-sparing measures necessary. In addition, costs for red cell packs have increased, in particular, for the generally compatible blood group 0 - an extra amount for rhesus negative blood. The present narrative review highlights, therefore, important news from the clinical transfusion medicine, immunohaematology and haemostaseology and their impact on daily transfusion practice. In this context, "blood management" is considered as one of the very effective blood-sparing measures, which focusses especially i) on the substitution of iron in case of depressed preoperative haemoglobin as well as ii) to elucidate disorders of coagulation by structured medical history and, subsequently, to balance possible need by a specific plan for substitution. Simultaneously, prospective studies are initiated to investigate how far the transfusion trigger of a patient can be lowered down to a still appropriate level. As far as consolidated findings are already available, they are described with regard to the single blood components and taking into account the cross-sectional guidelines of the "Bundesärztekammer" (Federal Physicians Chamber). Finally, initial evidence is provided characterising patient- and blood donor-specific, blood group-dependent features of a

    Previously,both primary and secondary anti-D alloimmunizations induced by “Asian type" DEL (RHD1227A allele) were observed in two incidents.We investigated how often these alloimmunization events occur.The transfusions of any D-negative patients were investigated in the First Affiliated Hospital of Xi'an Jiaotong University Medical College,China,during the entire 2009.The antigens of D,C,c,E,and e were routinely serotyped.The "Asian type" DEL variant was genotyped and the RHD heterozygote was determined through two published methods.The changes in anti-D levels were monitored by the indirect antiglobulin test (IAT) and flow cytometry.Thirty D-negative transfused patients were included in the study.We focused on 11 recipients who were transfused with packed red blood cells (RBCs) from DEL donors at least one time.Of those 11 recipients,seven were anti-D negative before transfusion and four were anti-D positive (one patient with an autoantibody).One of the seven pre-transfusion anti-D negative patients produced a primary-response anti-D after being transfused with 400 ml of DEL blood twice.All four pre-transfusion antibody positive patients were not observed hemoglobin (Hb) levels increased,as expected after transfusions.Two patients had an increase in anti-D from 1∶8 to 1∶64 by IAT,which was also shown by flow cytometry.None of the patients experienced an acute hemolytic episode.Our data indicated that the primary anti-D induced by DEL transfusion or the secondary anti-D elevated by DEL in a truly D-negative patient might not be unusual.We suggest that a truly D-negative childbearing-aged woman should avoid DEL transfusion to protect her from primary anti-D allosensitization.In addition,anti-D positive recipients should also avoid DEL red cell transfusion due to the delayed hemolytic transfusion reaction (DHTR).

    Full Text Available Abstract Background Blood transfusion (BT can be lifesaving for children; however, monitoring the quality of BT is important. The current study describes the quality of paediatric BT delivered in two district hospitals in north-east Tanzania in order to identify areas for quality assurance and improvement in the administration of BT. Methods All 166 children admitted in the paediatric wards and receiving BT through April to June 2007 were prospectively observed. Medical records, request forms and registers in the laboratories were reviewed to identify blood source, blood screening and indications for BT. BT was observation before, during and after transfusion process. Results Malaria related anaemia accounted for 98% of the BTs. Ninety-two percent of the children were assessed for paleness. Clinical signs such as difficult breathing and symptoms of cardiac failure were only assessed in 67% and 15% of the children respectively, prior to the BT decision. Pre-transfusion haemoglobin and body temperature were recorded in 2/3 of the patients, but respiratory rate and pulse rate were not routinely recorded. In 40% of BTs, the transfusion time exceeded the recommended 4 hours. The zonal blood bank (ZBB and local donors accounted for 10% and 90% of the blood, respectively. ABO and RhD typing and screening for HIV and syphilis were undertaken in all transfused blood. Evidence for hepatitis B or C infection was not checked except in the ZBB. Conclusion Criteria for BT are not always fulfilled; time to initiate and complete the transfusion is often unacceptable long and monitoring of vital signs during BT is poor. Blood from the ZBB was often not available and BT often depended on local donors which implied lack of screening for hepatitis B and C. It is recommended that an external supervision system be established to monitor and evaluate the quality of BT performance in the laboratories as well as in wards.

    Although it occurs worldwide, hepatitis E virus (HEV) infection in developed countries is generally foodborne. HEV infection is subclinical in most individuals. Although fulminant liver failure may occur, progression to chronic hepatitis is rare. This study describes a 41-year-old man with liver cirrhosis caused by non-alcoholic steatohepatitis and hepatocellular carcinoma within the Milan criteria. His liver function was classified as Child-Pugh grade C. Living donor liver transplantation (LDLT) was performed, and he was discharged from the hospital on postoperative day (POD) 22. However, his alanine aminotransferase concentration began to increase on POD 60 and HEV infection was detected on POD 81. Retrospective assessments of stored blood samples showed that this patient became positive for HEV RNA on POD 3. The liver donor was negative for anti-HEV antibodies and HEV RNA. However, the platelet concentrate transfused into the liver recipient the day after LDLT was positive for HEV RNA. The patient remained positive for HEV infection for 10 months. Treatment with 800 mg/day ribavirin for 20 weeks reduced HEV RNA to an undetectable level. In conclusion, this report describes a patient infected with HEV through a blood transfusion after LDLT, who progressed to chronic hepatitis probably due to his immunosuppressed state and was treated well with ribavirin therapy.

  18. Anemia During Sequential Induction Chemotherapy and Chemoradiation for Head and Neck Cancer: The Impact of Blood Transfusion on Treatment Outcome

    International Nuclear Information System (INIS)

    Purpose: Sequential treatment (chemotherapy followed by concomitant chemoradiation; CCRT) is increasingly being used for radical treatment of squamous cell cancer of the head and neck (SCCHN), which results in increased myelosuppression. In this study, we review the incidence of anemia and the effect of a policy of hemoglobin (Hb) maintenance by blood transfusion on disease outcomes in these patients. Methods and Materials: Retrospective review of the records of patients with SCCHN treated with sequential CCRT formed the basis of this study. The incidence of anemia and statistics on blood transfusion were documented. For the purpose of outcome analyses, patients were divided into four categories by (1) transfusion status, (2) nadir Hb concentration, (3) number of transfusion episodes, and (4) number of units of blood transfused (NOUT). Data on 3-year locoregional control (LRC), relapse-free survival (RFS), disease-specific survival (DSS), and overall survival (OS) were analyzed. Results: One hundred and sixty-nine patients were identified. The median follow-up was 23.6 months. The RFS (52% vs. 41%, p = 0.03), DSS (71% vs. 66%, p = 0.02), and OS (58% vs. 42% p = 0.005) were significantly better for patients who did not have a transfusion vs. those who did. The LRC, RFS, DSS, and OS were also significantly better for patients with nadir Hb level >12 vs. 4. Conclusion: Our study seems to suggest that blood transfusion during radical treatment for SCCHN might be detrimental. Further research should be undertaken into the complex interactions among tumor hypoxia, anemia, and the treatment of anemia before making treatment recommendations

    Multiple pretransplant sera obtained from alloimmunized renal transplant recipients were tested for the presence of antiidiotypic-like antibodies (AB2) that inhibit donor-specific HLA antibodies in the microlymphocytotoxicity assay. Fourteen patients received repetitive single-donor blood transfusions (SDT). In this patient group, sera were collected prior to each blood transfusion and prior to transplantation. Three additional patients were studied in whom prior donor-specific HLA antibodies had been lost over a period of 6 months preceding transplantation. Donor-specific AB2-like antibodies were found in the sera of 13/14 SDT patients who did not develop HLA antibodies, and in the 3 patients who had lost donor-specific HLA antibodies. All patients had received prior random blood transfusions in the year preceding the study. Five (38%) of the SDT patients had detectable donor-specific AB2 prior to the initiation of single-donor blood transfusion, presumably related to previous blood transfusions. In the remaining six SDT patients in whom complete serum sets were available, AB2 always appeared after the first blood transfusion. The specificity of HLA antibodies inhibited by AB2 was studied, and antibodies against HLA-A, -B, -C, -DR, and DQw were all identified. Thus, there was no predilection for patients to develop AB2 against locus-specific HLA gene products. This study also confirms the apparent polymorphism of putative crossreactive idiotypes. Approximately 25% of donor-specific HLA antibodies were not inhibited by relevant AB2. This study confirms and extends previous observations that alloimmunization is associated in many patients with the development of antiidiotypic-like antibodies that are capable of inhibiting the binding and cytotoxicity of HLA alloantibodies.

    Full Text Available BACKGROUND: Blood transfusion is a life - saving procedure. However , the recipient has the potential risk of acquiring transfusion - transmissible infections (TTI , important infectious agents being Human Immunodeficiency Virus (HIV , Hepatitis B & C viruses , and Treponema pallidum. AIM: This study was undertaken to know the prev alence of TTI in our hospital blood bank and hence evaluate the safety of the blood units . MATERIAL AND METHOD: The present study was conducted at the Blood Bank of our Medical College Hospital. Data was collected retrospectively for a 4.5 - year period from January 2008 to June 2012. Donor data including demographic details and results of the screening tests were recorded. RESULTS: In the 4.5 - year period , there were 7128 donors – both voluntary and replacement donors. The donors were in the age group 18 to 5 0 years. Out of the 116 donors tested positive for any test , there were 5 female donors and the 111 male donors. The donors who tested positive formed 1.6% of the total number of donors. The maximum number of donors were positive for HBsAg (n=47 , followed by positivity for HCV (n=45. The seroprevalence of HBsAg , HCV , HIV and Syphilis was 0.66% , 0.63% , 0.25% and 0.1% respectively. There was no case with smear positive for malaria parasite. CONCLUSION: The seroprevalence of TTI is minimal in our set up. The risk can be kept to a minimum by proper donor selection and testing of the collected units

    Red blood cell (RBC) transfusion therapy is a key component of comprehensive management of patients with sickle cell disease (SCD) and has increased over time as a means of primary and secondary stroke prevention. RBC transfusions also prove to be lifesaving for many acute sickle cell-related complications. Although episodic and chronic transfusion therapy has significantly improved the morbidity and mortality of patients with SCD, transfusions are not without adverse effects. This review addresses RBC transfusion methods, evidence-based and/or expert panel-based consensus on indications for chronic and episodic transfusion indications, and strategies to prevent and manage transfusion-related complications.

    Full Text Available TRALI is considered a serious hazard among immune complications of blood transfusion and its occurrence is admitted to be globally underestimated. Each type of blood product is likely to cause TRALI. We report here on two consecutive observations of TRALI caused by red blood cell concentrates, in which anti-HLA class I and class II antibodies resulting from post-gravitational allo-immunization were evidenced in donors. HLA class I and II antigenic community between recipients and donors' husbands were found and strong reacting IgG antibodies directed at several of those common antigens were detected in the donors' serum. Both donors had more than 3 pregnancies, raising the issue of blood donor selection or of plasma reduction for cellular products.

    The prevalence of A, B and AB blood types and of feline immunodeficiency virus (FIV) and feline leukaemia virus (FeLV) infection was determined in cats in Ireland, in order to determine risk factors for blood taken for transfusion purposes. EDTA blood samples were available from 137 non-pedigree cats and 39 pedigree cats (91 females and 85 males, aged four months to 15.0 years) in the Dublin area of Ireland. Of the 176 EDTA blood samples obtained, 112 (from 92 healthy cats and 20 sick cats) were tested for the presence of both FIV antibodies and FeLV antigens. Blood typing was performed using an immunochromatographic cartridge (CHROM; Alvedia). Testing for FIV and FeLV was performed by ELISA (SNAP FIV/FeLV Combo Test; Idexx Laboratories). Of the 39 pedigree cats, the majority (38 [97.4 per cent]) was type A, and only one (2.6 per cent) was type B. Of the 137 non-pedigree cats, the majority (116 [84.7 per cent]) was type A, 20 (14.6 per cent) were type B, and one (0.7 per cent) was type AB. Of the 92 healthy cats tested, the prevalence of FIV and FeLV positivity was 4.35 and 1.09 per cent, respectively. None of the 20 sick cats tested was FIV-positive; two (10 per cent) of the 20 sick cats were FeLV-positive. PMID:21498236

    2016-05-01

    Granulocyte transfusions are used to treat neutropenic patients with life-threatening bacterial or fungal infections that do not respond to anti-microbial drugs. Donor neutrophils that have been mobilized with granulocyte-colony stimulating factor (G-CSF) and dexamethasone are functional in terms of antibacterial activity, but less is known about their fungal killing capacity. We investigated the neutrophil-mediated cytotoxic response against C. albicans and A. fumigatus in detail. Whereas G-CSF/dexamethasone-mobilized neutrophils appeared less mature as compared to neutrophils from untreated controls, these cells exhibited normal ROS production by the NADPH oxidase system and an unaltered granule mobilization capacity upon stimulation. G-CSF/dexamethasone-mobilized neutrophils efficiently inhibited A. fumigatus germination and killed Aspergillus and Candida hyphae, but the killing of C. albicans yeasts was distinctly impaired. Following normal Candida phagocytosis, analysis by mass spectrometry of purified phagosomes after fusion with granules demonstrated that major constituents of the antimicrobial granule components, including major basic protein (MBP), were reduced. Purified MBP showed candidacidal activity, and neutrophil-like Crisp-Cas9 NB4-KO-MBP differentiated into phagocytes were impaired in Candida killing. Together, these findings indicate that G-CSF/dexamethasone-mobilized neutrophils for transfusion purposes have a selectively impaired capacity to kill Candida yeasts, as a consequence of an altered neutrophil granular content.

  9. The effects of gamma irradiation on blood and its components

    International Nuclear Information System (INIS)

    Although people belonging to the high-risk categories for infectious diseases have been asked not to donate blood, and donor blood is being tested by the most sensitive methods before distribution, viral hepatitis and acquired immuno deficiency syndrome (AIDS) transmissions by blood transfusion continue to be documented. Transmission may occur by false negative tests and the so-called ''window period'' of AIDS. The objective of this study was to determine the feasibility of application of gamma radiation sterilization to blood and its components by investigating possible alterations of important components of blood after irradiation. With the doses of 2.5-25 kGray, whole blood (WB) and freeze-dried plasma (FDP) were irradiated at 4 C and fresh frozen plasma (FFP) was irradiated at dry-ice temperature (-78.5C). There was no significant difference in the amount of sugar, protein, albumin and pH in WB, FDP, FFP and sodium, potassium in plasma between non-irradiated and irradiated samples (p>0.05). No appreciable difference of coagulation factors in FDP and FFP was noted before and after irradiation. In whole blood, the amount of plasma hemoglobin increased and blood cells decreased. There was an obvious decrease of sodium and increase of potassium in plasma from irradiated whole blood even with 2.5 kGy. The data of this study indicates that application of radiation sterilization to plasma, both freeze-dried and frozen, is possible when the proper conditions are applied. Whole blood, however, needs more data to evaluate this possibility

    Full Text Available Blood transfusion is a life-saving intervention and millions of lives are saved each year globally through this procedure. Unsafe transfusion practices put millions of people at risk of transfusion-transmissible infections (TTIs and it is mandatory to test the donated blood for blood borne infectious diseases. This is an alarming situation requiring immediate action in appropriate counseling of donors before and after testing of their blood. It is really a challenge for blood banks and motivators if a blood donor is positive for infectious diseases. What is the role of blood bank in helping or guiding the donors to overcome their anxiety and stress? How a medical social worker could psychologically support and guide them to act as cause ambassadors for voluntary blood donation? Guidance and counseling would help them to live positively. Health education, compassionate care and teaching coping mechanisms would encourage them in overcoming their stress and anxiety. [Natl J Med Res 2014; 4(1.000: 87-88

    Background The aim of this study was to investigate the association between red blood cell (RBC) transfusion and haematocrit values with outcomes in infants with univentricular physiology undergoing surgery for a modified Blalock-Taussig shunt. Material and methods This study included infants ≤ 2 months of age who underwent modified Blalock-Taussig shunt surgery at the Arkansas Children’s Hospital (2006–2012). Infants undergoing a Norwood operation or Damus-Kaye-Stansel operation with modified Blalock-Taussig shunt were excluded. Demographics, pre-operative, operative, daily laboratory data, and post-operative variables were collected. We studied the association between haematocrit and blood transfusion with a composite clinical outcome. Multivariable logistic regression models were fitted to study the probability of study outcomes as a function of haematocrit values and RBC transfusions after operation. Results Seventy-three patients qualified for inclusion. All study patients received blood transfusion within the first 48 hours after heart surgery. The median haematocrit was 44.3 (interquartile range [IQR] 42.5–46.2), and the median volume of RBC transfused was 28 mL/kg (IQR, 10–125) in the first 14 days after surgery. The overall in-hospital mortality rate was 13.6% (10 patients). A multivariable analysis adjusted for risk factors, including weight, prematurity, cardiopulmonary bypass and postoperative need for nitric oxide and dialysis, revealed no association between haematocrit values and RBC transfusion with the composite clinical outcome. Discussion We did not find an association between higher haematocrit values and increasing RBC transfusions with improved outcomes in infants with shunt-dependent pulmonary blood flow and univentricular physiology. The power of our study was small, which prevents any strong statement on this lack of association. Future multi-centre, randomised controlled trials are needed to investigate this topic in further

    Full Text Available Transfusion, just as any other medical intervention has both benefits and risks, which should be balanced for each patient so that the benefits outweigh the risks. Blood and its products are considered drugs and hence careful consideration of therapy is essential to minimize the potential adverse reactions. Moreover, alternative modes of treatment should be considered and final decision to transfuse should be based on individual patient evaluation. Reviews of blood transfusion practices have found that most surgical procedures do not require blood transfusion. This review is focused on the transfusion needs of the surgical patients.

    Full Text Available Abstract Background Malaria is an annual killer of over one million people globally and its essential co-morbidity is anaemia. Cord blood, because of its rich mix of foetal and adult haemoglobin, high platelet and WBC counts, hypo-antigenic nature, altered metabolic profile and high affinity for oxygen as well as its anti-malarial effect, is an ideal choice in malaria with anaemia, necessitating blood transfusion. Methods This paper presents an alternative protocol for fresh whole blood/packed cell transfusion from the hospital's biological waste resources, i.e., the placenta, after the birth of a healthy baby from a healthy mother. This collected blood was routinely transfused to patients admitted in our hospital with severe anaemia in the background of confirmed malaria. 94 units of placental umbilical cord whole blood were collected after lower uterine caesarean section (LUCS from consenting mothers (from 1st April 1999 to April 2005, and safely transfused to 39 informed, consenting patients (age varying from 8 to 72 years. The collected volume of cord blood from each placenta (Unit varied from 52 ml to 143 ml, with a mean packed cell volume of 48.9 ± 4.1 SD and a mean haemoglobin concentration of 16.4 Gm percent ± 1.6 Gm percent SD. The blood was immediately transfused after following the standard adult blood transfusion protocol of screening and cross-matching between the donor and the recipient. On occasion, the collected cord blood was preserved in the refrigerator, if no volunteer was readily available, and transfused within 72 hours of collection. Results Cord blood transfusion was tested on twenty two patients infected with Plasmodium falciparum and 17 patients with Plasmodium vivax. For inclusion in this study, the patient's plasma haemoglobin had to be 8 gm percent or less (the pre-transfusion haemoglobin in the malaria-infected patients in this series varied from 5.4 gm/dl to 7.9 gm/dl.

    No up-to-date overview of randomized controlled trials (RCTs) in red blood cell (RBC) transfusion exists. This systematic review examines the quantity and quality of the evidence for the clinical effects of RBC transfusion. One hundred forty-two eligible RCTs were identified through searches of The Cochrane Library (issue 4, 2009), MEDLINE (1950 to November 2009), EMBASE (1974 to November 2009), and other relevant sources. After data extraction and methodological quality assessment, trials were grouped by clinical specialty and type of RBC transfusion. Data analysis was predominantly descriptive. The 142 RCTs covered 11 specialties and 10 types of RBC transfusion. The number of included patients varied widely across the RCTs (median, 57; IQ range, 27-167). Most trials were single center comparing 2 parallel study arms. Overall, the reporting of methodological assessment was poor, although it improved markedly from 2001. Clinical areas with few trials are highlighted. Comparison with a study of RBC use in clinical practice highlighted a lack of correlation between the size of the evidence base for a given clinical specialty and the proportion of total RBC use by that clinical specialty. The gaps in the evidence base and the poor methodology of trials particularly in the past do not provide a strong evidence base for the use of RBC transfusions, but they indicate important targets for future research.

    Full Text Available There have been conflicting reports regarding the association of perioperative blood transfusion (PBT with oncologic outcomes including recurrence rates and survival outcomes in prostate cancer. We aimed to evaluate whether perioperative blood transfusion (PBT affects biochemical recurrence-free survival (BRFS, cancer-specific survival (CSS, and overall survival (OS following radical prostatectomy (RP for patients with prostate cancer.A total of 2,713 patients who underwent RP for clinically localized prostate cancer between 1993 and 2014 were retrospectively analyzed. We performed a comparative analysis based on receipt of transfusion (PBT group vs. no-PBT group and transfusion type (autologous PBT vs. allogeneic PBT. Univariate and multivariate Cox-proportional hazard regression analysis were performed to evaluate variables associated with BRFS, CSS, and OS. The Kaplan-Meier method was used to calculate survival estimates for BRFS, CSS, and OS, and log-rank test was used to conduct comparisons between the groups.The number of patients who received PBT was 440 (16.5%. Among these patients, 350 (79.5% received allogeneic transfusion and the other 90 (20.5% received autologous transfusion. In a multivariate analysis, allogeneic PBT was found to be statistically significant predictors of BRFS, CSS, and OS; conversely, autologous PBT was not. The Kaplan-Meier survival analysis showed significantly decreased 5-year BRFS (79.2% vs. 70.1%, log-rank, p = 0.001, CSS (98.5% vs. 96.7%, log-rank, p = 0.012, and OS (95.5% vs. 90.6%, log-rank, p < 0.001 in the allogeneic PBT group compared to the no-allogeneic PBT group. In the autologous PBT group, however, none of these were statistically significant compared to the no-autologous PBT group.We found that allogeneic PBT was significantly associated with decreased BRFS, CSS, and OS. This provides further support for the immunomodulation hypothesis for allogeneic PBT.

  5. A case of graft-versus-host disease following irradiated fresh blood transfusion

    International Nuclear Information System (INIS)

    We reported a case of a fatal graft-versus-host disease (GVHD) which developed in a 65-year-old, male patient which was considered to have been induced by irradiated fresh blood donated by his son after a coronary bypass surgery. Fresh blood was obtained from his relatives, and a 15 Gy irradiation was performed before transfusion. The diagnosis of acute GVHD was made by clinical symptoms and histological examinations of the skin and the bone marrow. He died of sepsis on the 19th post-operative day. The HLA typing of the lymphocytes, revealed that the patient had A 2, A 24, Bw 52, Bw 62, Cw 4, DR 2, and his son had A 24, Bw 52, DR 2. A 24 and Bw 52 were homogeneous making his son histocompatible with one of the patient's haplotype. This might well be attributable to the occurrence of GVHD in this case, meaning that 15 Gy irradiation was not sufficient for the prevention of this disease. (author)

  6. Impacts and concerns for vCJD in blood transfusion: current status.

    Science.gov (United States)

    MacGregor, I R; Prowse, C V

    2004-06-01

    The impact of vCJD upon blood transfusion practice hinges on its lymphoreticular involvement. B lymphocytes play a key supporting role for the capture and replication of infectivity by follicular dendritic cells of the lymphoid tissue in animal models of transmissible spongiform encephalopathies (TSE) and tonsils, spleen and appendix in man can harbour vCJD infectivity, a situation not seen with the other human TSEs. Leucodepletion of blood donations in the UK was implemented to reduce possible vCJD transmission and preliminary data suggests that white cell associated infectivity will be effectively removed although plasma infectivity will not. Blood screening assays are under development but none yet are ready for application. The conformation dependant immunoassay, based on differences in secondary and tertiary structure between normal and TSE-associated abnormal prion protein, has a sensitivity now approaching the best bioassay. Even so further development is needed to detect the fg/ml levels likely in the event that vCJD blood does contain abnormal prion, which is as yet unproven. Surrogate assays, such as for erythroid associated factor, may provide additional means of identifying donors harbouring vCJD. Validation of clearance of TSEs from pooled plasma products consistently demonstrates effective removal of the agents in downscaled systems and studies comparing vCJD, BSE and scrapie agents yield similar results. Many approaches to therapy are under investigation, in cell culture and animal models, targeted to normal or abnormal prion metabolism, including chemical and immunological interventions. Efficacy of quinacrine/chlorpromazine and pentosan polysulphate in a clinical setting, and agents yet to be used, will be more accurately known following recent agreement of clinical drug evaluation protocols.

    Full Text Available Background and Objective. The aim of this study was to determine factors associated with repeat blood donation. Methods. This was a cross-sectional study carried out among blood donors aged 18–65 years in northern Tanzania. The questionnaire was administered among 454 participants through the phone. Results. Of the 454 participants, the proportion of repeat donation was 63.9%. In the backward logistic regression analysis, the significant predictors were living in Arusha which had lower odds of repeat donation compared to those living in Kilimanjaro. Knowledge of time interval between donations increased odds of repeating donations. High intention increased odds of repeat donation compared to low intention. Altruistic score had minor effect on increasing odds of repeating donation. Conclusion. Repeat blood donation is affected by proximity of donating site, awareness of the blood donation interval, intention to donate, and experience on previous donation. We recommend continuous education concerning blood donors and donation among health workers and society as a whole; this will create awareness on motivational factors for repeat donations.

    Objective To analyze the relationship between hematimetric variation and the presence of clinical symptoms of hypoperfusion for indicating blood transfusion in patients undergoing total knee arthroplasty. Methods A retrospective analysis was conducted on data gathered from the medical files of 55 patients with a diagnosis of gonarthrosis, who underwent total knee arthroplasty at a hospital orthopedics and traumatology service between February 2011 and December 2012. The patients studied presented unilateral joint degeneration and fitted into the indications for surgical treatment. All the patients underwent a preoperative cardiological evaluation, presenting a pattern of ASA I–III and absence of blood dyscrasia, and preoperative hemoglobin measurements were made. However, no minimum hematimetric value was established for the surgical treatment; there were only clinical criteria for blood perfusion. Results Among the 55 patients, 35 were female and 20 were male, and the mean age was 68 years. Six patients underwent homologous blood transfusion, because of their clinical condition of tissue hypoperfusion, persistent hypotension, loss of consciousness, sweating and coercible vomiting. They presented postoperative hemoglobin of 7.5–8.8 g/dL. Conclusion For patients with falls in hemoglobin counts greater than 20% and values lower than 9 g/dL after the surgery, there is a possible need for blood transfusion, which should only be indicated when accompanied by major symptoms of tissue hypoperfusion.

    While β-thalassemia major (β-TM)-related physiological complications have been well established, less is known about implications for neuropsychological and cognitive function. The few existing studies have focused almost exclusively on children. We evaluated cognitive function in adult β-TM patients compared to healthy controls (study 1) and in β-TM patients before and after blood transfusion (study 2). Performance intelligence quotient (IQ) was evaluated with four subtests from the Wechsler Adult Intelligence Scale (WAIS-III). Attention functions were evaluated using the online continuous performance test (OCPT). The results of study 1 revealed poorer performance of β-TM patients on three of the four intelligence subtests, with significantly lower total performance IQ scores compared with controls. The percentage of participants with abnormal performance IQ (<85) was almost five times higher in the β-TM group (58%) than in the control group (12%). In study 2, significant differences were found in OCPT performance as a function of blood transfusion. Before transfusion, patients had higher rates of omission and commission errors, slower response times (RTs), and lower RT consistency than after transfusion. As β-TM patients' life expectancy is increasing, assessment and treatment of neurocognitive functions should become an integral part of appropriate follow-up to improve patients' quality of life.

    2009-10-01

    Full Text Available Transfusion related acute lung injury (TRALI is an uncommon but potentially fatal adverse reaction to transfusion of plasma containing blood components. We describe a case of 10-year-old male child with aplastic anemia, platelet count of 7800/΅l, B positive blood group who developed fever (39.2΀C, difficulty in breathing and cyanosis within 2 hrs after transfusion of a random platelet concentrate. Despite the best resuscitative efforts, the child died within next 24 hrs. The present case highlights the fact that TRALI should be kept as a differential diagnosis in all patients developing acute respiratory discomfort within 6 hrs of transfusion. Without a ′gold standard′ the diagnosis of TRALI relies on a high index of suspicion and on excluding other types of transfusion reactions. Notification to transfusion services is crucial to ensure that a proper investigation is carried out and at-risk donor and recipients can be identified, and risk reduction measures can be adopted.

    OBJECTIVE: To compare the effects of aprotinin on blood product use and postoperative complications in patients undergoing thoracic aortic surgery requiring deep hypothermic circulatory arrest. DESIGN: A retrospective study. SETTING: A university hospital. PARTICIPANTS: Nineteen patients who underwent elective or urgent thoracic aortic surgery. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The total number of units of packed red blood cells, fresh frozen plasma, and platelets was significantly less in the group that received aprotinin (p = 0.01, 0.04, and 0.01). The intraoperative transfusion of packed red blood cells and platelets, collection and retransfusion of cell saver, and postoperative transfusion of fresh frozen plasma were also significantly less in the aprotinin group (p = 0.01, 0.02, 0.01, and 0.05). No patient in either group sustained renal dysfunction or a myocardial infarction. Two patients who had not received aprotinin suffered from chronic postoperative seizures, and one patient who had received aprotinin sustained a perioperative stroke. CONCLUSIONS: Low-dose aprotinin administration significantly decreases blood product transfusion requirements in the setting of thoracic aortic surgery requiring deep hypothermic circulatory arrest, and it does not appear to be associated with renal or myocardial dysfunction.

  13. Effect of Massive Blood Transfusion on the Therapeutic Efficiency of Homogenic Bone Marrow in Acute Radiation Illness

    International Nuclear Information System (INIS)

    Simultaneously with bone-marrow transplantation, the authors replaced the blood of the lethally irradiated recipient animals with blood from the bone-marrow donor. From experiments on dogs and rabbits it became clear that replacing 86% of the recipient's blood with blood from the bone-marrow donor considerably reduces the therapeutic effect of bone-marrow transplantation. The authors consider that the main cause of the animals' early death in experiments combining bone-marrow transplantation and massive donor blood transfusions is a secondary syndrome resulting from the graft-versus-host reaction. This does not exclude the inverse possibility - that the development of a host-versus-graft reaction is due to the presence of a massive number of antigens of the donor blood in the blood of the recipient.

    1986-02-01

    Full Text Available The survival rate of 19 patients who underwent living-related kidney transplantation after donor-specific blood transfusions (DST was compared with that of 32 historical controls receiving transplants without DST. The graft survival rate of the DST group was 82% after two and three years. The graft survival rate of the DST group was significantly better than the 53% rate after two years obtained with the 32 historical controls (p less than 0.05. We tested sera from 16 DST-treated recipients to study the beneficial effect of DST on kidney allograft survival using the mixed lymphocyte culture (MLC serum inhibition test. The results demonstrated that MLC inhibitory factors were induced in the serum of the recipient after completion of DST. This inhibition of MLC was observed by treatment of responder lymphocytes with serum obtained three weeks after DST plus rabbit complement. The inhibitory effect was also specific for responder cells in anti-donor MLC. Regarding the correlation with rejection episodes, these MLC inhibitory factors were often observed in the non-rejection group (p less than 0.05. The data suggest that such factors may be anti-idiotypic antibodies and be associated with prolonged graft survival.

    Full Text Available Abstract OBJECTIVE To identify predictors of red blood cell transfusion (RBCT after cardiac surgery. METHOD A prospective cohort study performed with 323 adults after cardiac surgery, from April to December of 2013. A data collection instrument was constructed by the researchers containing factors associated with excessive bleeding after cardiac surgery, as found in the literature, for investigation in the immediate postoperative period. The relationship between risk factors and the outcome was assessed by univariate analysis and logistic regression. RESULTS The factors associated with RBCT in the immediate postoperative period included lower height and weight, decreased platelet count, lower hemoglobin level, higher prevalence of platelet count <150x10 3/mm3, lower volume of protamine, longer duration of anesthesia, higher prevalence of intraoperative RBCT, lower body temperature, higher heart rate and higher positive end-expiratory pressure. The independent predictor was weight <66.5Kg. CONCLUSION Factors associated with RBCT in the immediate postoperative period of cardiac surgery were found. The independent predictor was weight.

    In this work we present the application of a method for the identification of homologous blood transfusions using forensic genetic techniques based on DNA typing. Ex vivo mixtures of human blood samples - either whole blood or red blood cell concentrates - simulating homologous blood transfusions at different percentages of the donor were typed for a panel of 16 highly variable DNA short tandem repeats (STR). Tested samples included also mixtures, which gave false-negative results if assayed by the reference flow cytofluorimetric method, which is based on the recognition of target antigens located on the membrane of the red blood cell. The recognition of triplets and quadruplets at various loci gave information of the presence of cells belonging to different individuals, as it is the case for homologous blood transfusions. Specificity and sensitivity of the method were assessed in the validation study. The method proved to be unequivocally specific since it was able to recognize all single profiles of each individual, clearly discriminating them from mixtures. Sensitivity resulted as a consequence of the percentage of the donor aliquot in the total volume of the mixture. Although the source of DNA in a blood sample is represented only by nucleated white blood cells, the same procedure resulted effective also in detecting mixtures of red blood cell concentrates (RBCC) from leukodepletion procedure: DNA of the donor from the residual white blood cells resulted still detectable, even if with an expected loss of sensitivity. The proposed approach may contribute to reduce the risk of false-negative results, which may occur using the reference cytofluorimetric method. PMID:27175858

    The autofluorescence of blood components of healthy volunteers and cancer patients of different etiology were analyzed using a steady-state spectrofluorometer. A significant contrast between healthy and diseased blood could be established. Blood components of patients of gastric cancer, breast cancer and Hodgkin's lymphoma showed distinct and enhanced fluorescence band (around 630 nm) due to the porphyrin fluorophore. From the ratio fluorometry, a correlation to the stages of cancer could be also brought forth. We could indicate reasonably well the features of early stages and the growth rate of a few cancers and benign tumors.

    Full Text Available OBJECTIVES: Transfusion of allogeneic blood is still common in orthopedic surgery. This analysis evaluates from the perspective of a German hospital the potential cost savings of Epoetin alfa (EPO compared to predonated autologous blood transfusions or to a nobloodconservationstrategy (allogeneic blood transfusion strategyduring elective hip and knee replacement surgery. METHODS: Individual patients (N = 50,000 were simulated based on data from controlled trials, the German DRG institute (InEK and various publications and entered into a stochastic model (Monte-Carlo of three treatment arms: EPO, preoperative autologous donation and nobloodconservationstrategy. All three strategies lead to a different risk for an allogeneic blood transfusion. The model focused on the costs and events of the three different procedures. The costs were obtained from clinical trial databases, the German DRG system, patient records and medical publications: transfusion (allogeneic red blood cells: €320/unit and autologous red blood cells: €250/unit, pneumonia treatment (€5,000, and length of stay (€300/day. Probabilistic sensitivity analyses were performed to determine which factors had an influence on the model's clinical and cost outcomes. RESULTS: At acquisition costs of €200/40,000 IU EPO is cost saving compared to autologous blood donation, and cost-effective compared to a nobloodconservationstrategy. The results were most sensitive to the cost of EPO, blood units and hospital days. CONCLUSIONS: EPO might become an attractive blood conservation strategy for anemic patients at reasonable costs due to the reduction in allogeneic blood transfusions, in the modeled incidence of transfusion-associated pneumonia andthe prolongedlength of stay.

    2012-01-01

    Full Text Available Background: Deferring blood donors who admit to high-risk behavior on questioning are likely to eliminate those in window period for transfusion transmitted infections (TTI. However, many questions have been implemented in some countries as part of donor history questionnaire, based on precautionary principle and not on evidence, and can result in increased donor losses. This study aims to identify effective risk-directed questions having high predictive value, in local context which can form part of blood donor deferral policies. For this, a case control study in a hospital blood bank having donation services was carried out prospectively over a period of three years. Materials and Methods: Two hundred and twenty donors, who were repeatedly reactive for HBsAg, anti-HCV, anti-HIV with EIA, and syphilis with TPHA, were the cases. Eight hundred and eighty four controls were the donors who tested negative for all TTI test. All donors answered seven hepatitis risk directed questions and their responses and reactivity status for TTI were used for statistical analysis with SPSS ver. 15. Results: Positive predictive value for history of jaundice at any age for HBsAg was 20%, while PPV for history of surgery in previous six months for both HBsAg and anti-HCVHCV was also around 20%, based on pretest probability of 7%. The post-test probability for these questions was around 30%. Odds ratios with 95% CI did not reveal any significant association of hepatitis with any of seven questions. Donor losses after deferring on basis of two questions were 5.3% per year, while deferral rate after all seven questions was 20%. Conclusions: Donors should be permanently deferred if there is history of jaundice at any age, while deferral period after surgery should be one year. Other risk-directed questions should not be used to defer donors. Donor deferral policies should be evidence based and questions with proven efficacy should be made part of donor history

    2012-06-01

    Full Text Available Abstract Background Total hip and knee arthroplasties are two of the most commonly performed procedures in orthopedic surgery. Different blood-saving measures (BSMs are used to reduce the often-needed allogenic blood transfusions in these procedures. A recent large randomized controlled trial showed it is not cost effective to use the BSMs of erythropoietin and perioperative autologous blood salvage in elective primary hip and knee arthroplasties. Despite dissemination of these study results, medical professionals keep using these BSMs. To actually change practice, an implementation strategy is needed that is based on a good understanding of target groups and settings and the psychological constructs that predict behavior of medical professionals. However, detailed insight into these issuses is lacking. Therefore, this study aims to explore which groups of professionals should be targeted at which settings, as well as relevant barriers and facilitators that should be taken into acount in the strategy to implement evidence-based, cost-effective blood transfusion management and to de-implement BSMs. Methods The study consists of three phases. First, a questionnaire survey among all Dutch orthopedic hospital departments and independent treatment centers (n = 99 will be conducted to analyze current blood management practice. Second, semistructured interviews will be held among 10 orthopedic surgeons and 10 anesthesiologists to identify barriers and facilitators that are relevant for the uptake of cost-effective blood transfusion management. Interview questions will be based on the Theoretical Domains Interview framework. The interviews will be followed by a questionnaire survey among 800 medical professionals in orthopedics and anesthesiology (400 professionals per discipline in which the identified barriers and facilitators will be ranked by frequency and importance. Finally, an implementation strategy will be developed based on the results

    Full Text Available Removal of leucocytes from various blood products has been shown to minimize Febrile nonhemolytic transfusion reactions, HLA alloimmunization, platelet refractoriness in multitransfused patients and prevention of transmission of leukotropic viruses such as EBV and CMV. Rapidly growing size of hemato-oncological patients in our country requiring multiple transfusion of blood and components during the course of their management pose a great challenge to transfusion services to provide them red cell and platelet antigen matched products in alloimmunized subjects. Thus removal of leucocytes below a certain threshold, ≤ 5 x 10 6 in a blood component certainly helps in prevention of alloimmunization and associated risks in these patients. Currently the best Leucoreduction can be achieved with the help of 3rd and 4th generation leukofilters, both in laboratory and patient bed side, and state of the art apheresis devices. The present article briefly reviews the current literature for pros and cons of leucofilteration and its scope of implementation in the cost constrained settings.

    2014-07-01

    Transfusion-related acute lung injury (TRALI) is a serious clinical syndrome associated with the transfusion of plasmacontaining blood components. Recently, TRALI has come to be recognized as the leading cause of transfusion-related mortality. This complication typically presents as shortness of breath, hypoxemia, hypotension, fever, and non cardiogenic pulmonary edema, occurring within 6 h after transfusion. Although the mechanism of TRALI has not been exactly known, it has been associated with human leukocyte antigen antibodies and with biologically active mediators in stored cellular blood components. We, hereby, present a case of a patient with dengue fever who developed acute lung injury (ALI), presumably TRALI, after transfusion of platelet concentrates. He was treated with supportive measures and mechanical ventilation. Greater knowledge and increased awareness especially amongst the clinicians regarding TRALI is needed for prevention and treatment of this potentially severe complication of blood/component transfusion.

    The CD40 ligand (CD40L) is a transmembrane molecule of crucial interest in cell signaling in innate and adaptive immunity. It is expressed by a variety of cells, but mainly by activated T-lymphocytes and platelets. CD40L may be cleaved into a soluble form (sCD40L) that has a cytokine-like activity. Both forms bind to several receptors, including CD40. This interaction is necessary for the antigen specific immune response. Furthermore, CD40L and sCD40L are involved in inflammation and a panoply of immune related and vascular pathologies. Soluble CD40L is primarily produced by platelets after activation, degranulation and cleavage, which may present a problem for transfusion. Soluble CD40L is involved in adverse transfusion events including transfusion related acute lung injury (TRALI). Although platelet storage designed for transfusion occurs in sterile conditions, platelets are activated and release sCD40L without known agonists. Recently, proteomic studies identified signaling pathways activated in platelet concentrates. Soluble CD40L is a good candidate for platelet activation in an auto-amplification loop. In this review, we describe the immunomodulatory role of CD40L in physiological and pathological conditions. We will focus on the main signaling pathways activated by CD40L after binding to its different receptors. PMID:25479079

    Full Text Available Abstract Background Inadequate surgical hemostasis may lead to transfusion and/or other bleeding-related complications. This study examines the incidence and costs of bleeding-related complications and/or blood product transfusions occurring as a consequence of surgery in various inpatient surgical cohorts. Methods A retrospective analysis was conducted using Premier's Perspective™ hospital database. Patients who had an inpatient procedure within a specialty of interest (cardiac, vascular, non-cardiac thoracic, solid organ, general, reproductive organ, knee/hip replacement, or spinal surgery during 2006-2007 were identified. For each specialty, the rate of bleeding-related complications (including bleeding event, intervention to control for bleeding, and blood product transfusions was examined, and hospital costs and length of stay (LOS were compared between surgeries with and without bleeding-related complications. Incremental costs and ratios of average total hospital costs for patients with bleeding-related complications vs. those without complications were estimated using ordinary least squares (OLS regression, adjusting for demographics, hospital characteristics, and other baseline characteristics. Models using generalized estimating equations (GEE were also used to measure the impact of bleeding-related complications on costs while accounting for the effects related to the clustering of patients receiving care from the same hospitals. Results A total of 103,829 cardiac, 216,199 vascular, 142,562 non-cardiac thoracic, 45,687 solid organ, 362,512 general, 384,132 reproductive organ, 246,815 knee/hip replacement, and 107,187 spinal surgeries were identified. Overall, the rate of bleeding-related complications was 29.9% and ranged from 7.5% to 47.4% for reproductive organ and cardiac, respectively. Overall, incremental LOS associated with bleeding-related complications or transfusions (unadjusted for covariates was 6.0 days and ranged from 1

    Full Text Available BACKGROUND: Several irregular red blood cell alloantibodies, produced by alloimmunization of antigens in transfusions or pregnancies, have clinical importance because they cause hemolysis in the fetus and newborn and in transfused patients. OBJECTIVE: a prospective analysis of patients treated by the surgical and clinical emergency services of Hospital de Clínicas of the Universidade Federal do Triângulo Mineiro (HC/UFTM, Brazil was performed to correlate alloimmunization to clinical and epidemiological data. METHODS: Blood samples of 143 patients with initial negative antibody screening were collected at intervals for up to 15 months after the transfusion of packed red blood cells. Samples were submitted to irregular antibody testing and, when positive, to the identification and serial titration of alloantibodies. The Fisher Exact test and Odds Ratio were employed to compare proportions. RESULTS: Fifteen (10.49% patients produced antibodies within six months of transfusion. However, for 60% of these individuals, the titers decreased and disappeared by 15 months after transfusion. Anti-K antibodies and alloantibodies against antigens of the Rh system were the most common; the highest titer was 1:32 (anti-K. There was an evident correlation with the number of transfusions. CONCLUSIONS: Given the high incidence of clinically important red blood cell alloantibodies in patients transfused in surgical and clinical emergency services, we suggest that phenotyping and pre-transfusion compatibilization for C, c, E, e (Rh system and K (Kell system antigens should be extended to all patients with programmed surgeries or acute clinical events that do not need emergency transfusions.OBJETIVO: Vários aloanticorpos irregulares antieritrocitários, produzidos por sensibilizações a antígenos estranhos durante gestações ou transfusões, possuem importância clínica por provocarem hemólise no feto ou recém-nascido e/ou no receptor de sangue.

    Full Text Available Transfusion-related acute lung injury (TRALI is a complication following transfusion of blood products and is potentially a life-threatening adverse event of transfusion. The first case of fatal pulmonary edema following transfusion was reported in the 1950s. In recent time, TRALI has developed from an almost unknown transfusion reaction to the most common cause of transfusion related major morbidities and fatalities. A clinical definition of TRALI was established in 2004, based on acute respiratory distress which has temporal association with transfusion of blood components. In 2008 a distinction between classic and delayed syndrome was proposed. However, pathophysiology of TRALI still remains controversial. A number of different models were proposed to explain the pathogenesis. The two, presently most accepted models, are not mutually exclusive. The first is the antibody mediated model and the second is the two-event model.In this review article the definition of TRALI, patient predisposition, treatment, prevention and reporting guidelines are examined. The current knowledge on the topic TRALI is summarized.

    Full Text Available ABO and Rhesus (Rh blood group antigens are hereditary characters and are useful in population genetic studies, in resolving medico-legal issues and more importantly in compatibility test in blood transfusion practice. Data on frequency distribution of ABO and Rh-D in Niger-Delta region of Nigeria are not available; hence we made an attempt to retrospectively analyze the records on the blood donors, transfusion recipients and patients attending antenatal care or some other medical interventions. Over a twenty-year period between 1986 and 2005, a total of 160,431 blood samples were grouped for ABO and Rh-D at the blood bank of the University of Benin Teaching Hospital, Benin City, Nigeria. Blood group distribution among these samples showed phenotypes A, B, AB and O as 23.72%, 20.09%, 2.97% and 53.22%, respectively. The Rh-D negative phenotype was found among 6.01% of the samples tested.

    The impact of transfusing fresher vs older red blood cells (RBCs) on patient-important outcomes remains controversial. Two recently published large trials have provided new evidence. We summarized results of randomized trials evaluating the impact of the age of transfused RBCs. We searched MEDLINE, EMBASE, CINAHL, the Cochrane Database for Systematic Reviews, and Cochrane CENTRAL for randomized controlled trials enrolling patients who were transfused fresher vs older RBCs and reported outcomes of death, adverse events, and infection. Independently and in duplicate, reviewers determined eligibility, risk of bias, and abstracted data. We conducted random effects meta-analyses and rated certainty (quality or confidence) of evidence using the GRADE approach. Of 12 trials that enrolled 5229 participants, 6 compared fresher RBCs with older RBCs and 6 compared fresher RBCs with current standard practice. There was little or no impact of fresher vs older RBCs on mortality (relative risk [RR], 1.04; 95% confidence interval [CI], 0.94-1.14; P = .45; I(2) = 0%, moderate certainty evidence) or on adverse events (RR, 1.02; 95% CI, 0.91-1.14; P = .74; I(2) = 0%, low certainty evidence). Fresher RBCs appeared to increase the risk of nosocomial infection (RR, 1.09; 95% CI, 1.00-1.18; P = .04; I(2) = 0%, risk difference 4.3%, low certainty evidence). Current evidence provides moderate certainty that use of fresher RBCs does not influence mortality, and low certainty that it does not influence adverse events but could possibly increase infection rates. The existing evidence provides no support for changing practices toward fresher RBC transfusion. PMID:26626995

    Background: Febrile nonhemolytic transfusion reactions (FNHTRs) are relatively common complications associated with allogenic transfusion. White blood cells (WBCs or leukocytes) are considered to be an important cause of FNHTRs; the rate of WBC derived pro-inflammatory cytokines increase with storage due to active synthesis of cytokines by these cells. The removal of the WBCs before storage will prevent the accumulation of cytokines during storage that leads to a reduction in the number of FN...

    Introduction Blood transfusions remain a substantial source of HIV in SSA particularly among children and pregnant women. Aims and objectives: This aim of this retrospective study was to investigate the prevalence of p24 antigen among HIV antibody seronegative blood donors in Sokoto, North West Nigeria. Methods A total of 15,061 HIV antibody negative blood donors with mean age and age range (29.2 ± 8.18 and 18-50 years) were screened for p24 antigen between January 2010 to July 2013 using the Diapro Diagnostic immunoassay kit for P24 antigen (King Hawk Pharmaceuticals Beijing China). Results The overall prevalence of p24 antigen among the HIV antibody negative donors sample was 5.84%. The yearly prevalence was 9.79, 8.12, 2.7 and 2.84% respectively in 2010, 2011, 2012 and 2013. Of the total number of blood donor tested, 14,968 (99.38%) were males while 93 (0.62%) were females. The prevalence of P24 antigen was significantly higher among male blood donors 873 (5.8%) compared to females 7(0.05%), (p= 0.001). P24 positivity was significantly higher among blood group O blood donors compared to A, B and AB donors (494 (3.29%) compared to 184 (1.89%), 196 (1.30%) and 6 (0.04%)) respectively, p = 0.001). The prevalence of P24 antigen was significantly higher among Rhesus positive blood donors compared to Rhesus negative (807 (5.36%) versus 73 (0.48%), p =0.001). Conclusion Blood transfusion in Nigeria is associated with increased risk of HIV transmission. There is the urgent need to optimize the screening of blood donors in Nigeria by the inclusion of p24 antigen testing into the blood donor screening menu. The Nigerian government urgently need to adopt the WHO blood safety strategies to reduce the risk of transmission of HIV through blood transfusion. PMID:25419301

    Full Text Available Objective: Homologous blood transfusion after open heart surgery puts a tremendous load on the blood banks. This prospective randomized study evaluates the efficacy of infusing back residual cardiopulmonary bypass (CPB circuit i.e., pump blood as a means to reduce homologous transfusion after coronary artery bypass surgery (CABG and whether its use increases postoperative drainage. Materials and Methods: Sixty-seven consecutive patients who underwent elective CABGs under CPB were randomized into 2 groups: (1 cases where residual pump blood was used and (2 controls where residual pump blood was not used. Patients were monitored for hourly drainage on the day of surgery and the 1 st postoperative day and the requirements of homologous blood and its products. Data were matched regarding change in Hemoglobin, Packed Cell Volume and coagulation parameters till 1st postoperative day. All cases were followed up for three years. Results: There was a marginal reduction in bleeding pattern in the early postoperative period in the cases compared to controls. The requirement of homologous blood and its products were also reduced in the cases. Conclusions: The use of CPB circuit blood is safe in the immediate postoperative period. The requirement of homologous blood transfusion can come down if strict transfusion criteria are maintained.

    Background: Transfusion-associated hepatitis B viral infection continues to be a major problem in India even after adoption of mandatory screening for HBsAg by ELISA method. The high incidence of TAHBV is reported in patients receiving multiple transfusions.

    Objective: To study the seroprevalence of hepatitis B core antibody among healthy voluntary blood donors

    Subjects and Methods: The study was conducted in the department of Transfusion Medicine of a tertiary care referral hospital. A total of 12,232 volunteers after passing through the stringent criteria were selected for blood donation. Donor samples were tested for all mandatory transfusion transmissible infections and anti HBc IgM (Monolisa HBc IgM PLUS:BIO-RAD, France. Reactive results were confirmed by repeat testing in duplicate. Donor data was analyzed using SPSS software and Chi-square test was used to calculate the significance of difference between the groups.

    Results:A total of 12,232 healthy voluntary blood donors were recruited. Majority (93.4% were males. Median age of donor population was 26 years (range: 18-60 years. Eighty six (0.7% were positive for HBsAg, which comes under “low prevalence (<2% zone” as per WHO. On screening for HBcAg Ig M, 15 (0.1% were found to be positive and none were HBsAg reactive. There was no significance of difference in the mean age between reactive and non-reactive donors.

    Conclusion:Evaluating the usefulness of anti-HBc screening is critical. Anti HBcAg IgM screening may be included in routine screening of donors as it is an indicator of occult HBV during window period. The cost and the unnecessary wastage of the blood units when they are positive for anti HBsAg along with the core antibody need to be studied.

    This study focuses on the requirement of JWs to refuse medical blood transfusions. We identified a life-death cognitive dissonance among JWs, with the opposing cognitions of being willing to sacrifice life by religious standards, while being unwilling to do so. Using a theory that connects cognitive dissonance with the need to regulate difficult emotions to analyze our qualitative data material, we identified two sets of dissonance reduction strategies among the JWs. Set 1 was tied to the individual-group: selective focus on eternal life, a non-blood support and control system, and increased individualization of treatment choices. Set 2 was in the religion versus medicine intersection: denial of risk combined with optimism, perception of blood as dangerous, and use of medical language to underscore religious doctrine.

    Full Text Available Deep hypothermia, which is used during thoracic aortic surgery for neuroprotection, is associated with coagulation abnormalities in animal and in vitro models. However, there is a paucity of data regarding the impact of deep hypothermia duration on perioperative bleeding. The objective of the current study was to examine the relationship between the duration of deep hypothermia and perioperative bleeding. A retrospective review of 507 consecutive thoracic aortic surgery patients who had surgery with deep hypothermic circulatory arrest was performed. The degree of bleeding and coagulopathy was estimated using perioperative transfusion. Log linear modeling with Poisson regression was used to analyze the relationship between deep hypothermia duration and perioperative bleeding, while controlling for other preselected variables. There was a significant association between deep hypothermia duration and RBC transfusion (P = 0.001. There was no significant association between deep hypothermia duration and FFP and platelet transfusion (P = 0.18 and P = 0.06. The association between deep hypothermia duration and the amount of bleeding (RBC transfusion was dependent on total CPB time. In general, for shorter CPB times (approximately 120 to 180 minutes there was an upward sloping line or positive relationship between deep hypothermia duration and bleeding. However, for cases with longer CPB times (300 to 360 minutes, there was no such relationship. The relationship between deep hypothermia duration and perioperative bleeding is dependent on CPB time. For surgeries with short CPB times (120 to 180 minutes, prolonged deep hypothermia is associated with increased post-operative bleeding, as estimated by RBC transfusion. For cases with longer CPB times (300 to 360 minutes, there appears to be no relationship.

    Full Text Available Abstract Background In China, high prevalence of HBV and HCV parallels with the growing epidemic of syphilis and HIV in the general population poses a great threat to blood safety. This study investigated the prevalence of serologic markers for transfusion transmissible infections (TTIs among four Chinese blood centers. Methods We examined whole blood donations collected from January 2000 through December 2010 at four Chinese blood centers. Post-donation testing of TTIs (HIV, HBV, HCV and syphilis were conducted using two different enzyme-linked immunosorbent assay kits for each seromarker. The prevalence of serologic markers for TTIs (% was calculated and additional analysis was conducted to examine donor characteristics associated with positive TTIs serology. Results Of the 4,366,283 donations, 60% were from first-time donors and 40% were from repeated donors. The overall prevalence of HIV, HBsAg, HCV and syphilis was 0.08%, 0.86%, 0.51% and 0.47%, respectively. The prevalence profile of TTIs varied among different blood centers and appeared at relatively high levels. Overall, the prevalence of HBsAg and HCV demonstrated a decline trend among four blood centers, while the prevalence of HIV and syphilis displayed three different trends: constantly steady, continually increasing and declining among different centers. Conclusions This study reflects the risk of TTIs has been greatly reduced in China, but blood transfusion remains an ongoing risk factor for the spread of blood-borne infections, and further work and improvements are needed to strengthen both safety and availability of blood in China.

    Full Text Available Liver transplant procedures require the most blood components, despite the fact that blood use in liver transplantation has declined dramatically over the last decade. Liver transplant recipients present unique challenges, not only in terms of blood supply, but also requirements for specialized blood components, serologic problems, and immunologic effects of transfusion on both the allograft and the recipient. The cause of intraoperative blood loss in liver transplantation is multifactorial, due to both technical factors and poor coagulation control. This procedure carries the risk of massive blood loss, which requires massive transfusions and is associated with postoperative infections, reduced graft survival, multi-organ dysfunction, and higher risk of mortality. Efforts to reduce intraoperative bleeding leading to limitation of blood transfusions are desirable to improve results and also to control costs.

    Full Text Available Iatrogenous transmission of Trypanosoma cruziby blood transfusion was suggested as a potential risk by Pellegrino (1949. Seropositive blood donors in Mexico were first reported in 1978, however, limited information is available due to small sampling, the use of heterogeneous serologic assays, and geographically limited studies. A wide survey carried out in 18 out of the 32 states of Mexico, showed a national mean of 1.6% seropositive among 64,969 donors, ranging from 0.2 to 2.8%. In the present study, we have screened 43,048 voluntary blood donors in a period of five years at the Instituto Nacional de Cardiología I. Chávez, a concentration hospital located in Mexico city which serves mainly the metropolitan area and accepts from all over the country. Standardized ELISA and IIF were used to identify seropositive individuals in addition to hemoculture, PCR and standard 12 lead ECG tests that were applied to a group of seropositive patients (29/161. The result showed a seropositivity of 0.37% (161/43,048. From the group of seropositive individuals 40% (12/29 were potential carriers of T. cruzi at the donation time and 5/29 had subclinical ECG abnormalities. Parasitological tests performed in 70 erythrocyte and platelet fractions from seropositive units (70/161 showed negative results. Our findings strongly support T. cruzi screening in the transfusion medicine practice and identify subclinical heart disease among seropositive blood donors.

    This debate questions the donor's position within the transfusional framework. How are blood donation regulations initiated and implemented? Experts called upon this question insist on the necessity to better inform about such regulations so that they can be rapidly approved and in order to keep donors from adverse reactions linked to blood donations. How to make donors' rejections more tolerable? Contra-indications are a source of anxiety for the person whose blood sample is not accepted. While blood transfusion has never been safer in the past than it is today in wealthy countries, one should ask the question whether the donor is or not the victim of doubts still weighing down on this activity. Implementing the precautionary principle may indeed lead transfusion supervisors to take brutal decisions detrimental to the donor, seeming rather inspired by political or media pressures than calling on scientific or economic rigorous principles. What does the donor selection aim at in terms of prevention and public health? What about the renewal of donor associations' directors? Where are we at with the homosexual rejection trends? Such are the issues as those induced by the current debate. PMID:16959516

    The use of blood infusion in large amounts is increasing sharply. Increased knowledge of blood group antigens has alerted physicians to the possible hazards of hemolytic reactions to subgroups that must be eliminated by proper cross-matching techniques. Multiple transfusions of preserved blood often defeat their purpose in control of bleeding, for thrombocytopenia is enhanced. Careful selection of blood or preparations of plasma concentrates offer increased protection to the recipient.Plastic bag equipment increases the yield of viable platelets and keeps blood in usable condition for longer periods of storage. The use of multiple transfusions has complicated the selection of preserved blood to control pigment metabolism. PMID:13500210

    Full Text Available Resuscitation of a severely traumatised patient with the administration of crystalloids, or colloids along with blood products is a common transfusion practice in trauma patients. The determination of this review article is to update on current transfusion practices in trauma. A search of PubMed, Google Scholar, and bibliographies of published studies were conducted using a combination of key-words. Recent articles addressing the transfusion practises in trauma from 2000 to 2014 were identified and reviewed. Trauma induced consumption and dilution of clotting factors, acidosis and hypothermia in a severely injured patient commonly causes trauma-induced coagulopathy. Early infusion of blood products and early control of bleeding decreases trauma-induced coagulopathy. Hypothermia and dilutional coagulopathy are associated with infusion of large volumes of crystalloids. Hence, the predominant focus is on damage control resuscitation, which is a combination of permissive hypotension, haemorrhage control and haemostatic resuscitation. Massive transfusion protocols improve survival in severely injured patients. Early recognition that the patient will need massive blood transfusion will limit the use of crystalloids. Initially during resuscitation, fresh frozen plasma, packed red blood cells (PRBCs and platelets should be transfused in the ratio of 1:1:1 in severely injured patients. Fresh whole blood can be an alternative in patients who need a transfusion of 1:1:1 thawed plasma, PRBCs and platelets. Close monitoring of bleeding and point of care coagulation tests are employed, to allow goal-directed plasma, PRBCs and platelets transfusions, in order to decrease the risk of transfusion-related acute lung injury.

We conducted a systematic review and meta-analysis to investigate the relationship between PBT and the clinical outcomes of RC patients.We searched MEDLINE, EMBASE, the Cochrane library and BIOSIS previews to identify relevant literature for studies that focused on the relationship of PBT and outcomes of patients undergoing RC. A fixed or random effects model was used in this meta-analysis to calculate the pooled hazard ratio (HR with 95% confidence intervals (CIs.A total of 7080 patients in 6 studies matched the selection criteria. Aggregation of the data suggested that PBT in patients who underwent RC correlated with increased all-cause mortality, cancer-specific mortality and cancer recurrence. The combined HRs were 1.19 (n = 6 studies, 95% CI: 1.11-1.27, Z = 4.71, P<0.00001, 1.17 (n = 4 studies, 95% CI: 1.06-1.30, Z = 3.06, P = 0.002, 1.14 (n = 3 studies, 95% CI: 1.03-1.27, Z = 2.50, P = 0.01, respectively. The all-cause mortality associated with PBT did not vary by the characteristics of the study, including number of study participants, follow-up period and the median blood transfusion ratio of the study.Our data showed that PBT significantly increased the risks of all-cause mortality, cancer-specific mortality and cancer recurrence in patients undergoing RC for bladder cancer.

    Data collection can be enhanced with the use of computers. Care must be taken, however, to ensure that the data collected have a purpose and meet either the quality assessment needs or business functions of the transfusion service. Required data elements are frequently in several data repositories and must be merged to obtain needed information. Effective data collection may be hindered by several factors, including a lack of data elements in the computer systems, data retention limitations, and changes in the computer system or collection needs. Personal computers with commonly available spreadsheet and database management software are useful in preparing summarized reports. An ideal report is legibly printed on one side of a sheet of paper and includes graphs and charts that enhance data presentation and facilitate trend analysis. PMID:9124230

    Full Text Available Transfusion-related acute lung injury (TRALI is a common adverse effect of blood transfusion that is often underrecognised and underreported. We would like to report a case of TRALI after the replantation and transfusion of blood components in a male patient who had sustained a complete amputation of the right upper extremity. The level of amputation was just proximal to the humeral condyles. Replantation was performed 5 hours after the accident and 36 units of blood products were transfused intraoperatively. Subsequently, during the early postoperative period, TRALI was revealed. In this case report, the circumstances of this injury and preventive measures are discussed to understand and recognise this condition in order to reduce the morbidity and mortality of TRALI. It is important to distinguish TRALI from other causes of pulmonary oedema because early diagnosis and management are associated with a favourable outcome.

  12. HBV, HCV and HIV seroprevalence among blood donors in Istanbul, Turkey: how effective are the changes in the national blood transfusion policies?

    Full Text Available The national blood transfusion policies have been changed significantly in recent years in Turkey. The purpose of this study was to determine the prevalence of HBV, HCV, and HIV in blood donors at the Red Crescent Center in Istanbul and to evaluate the effect of changes in the national blood transfusion policies on the prevalence of these infections. The screening results of 72695 blood donations at the Red Crescent Center in Istanbul between January and December 2007 were evaluated retrospectively. HBsAg, anti-HCV, and anti-HIV-1/2 were screened by microparticle enzyme immunoassay (MEIA method. Samples found to be positive for anti-HIV 1/2 and anti-HCV were confirmed by Inno-Lia HCV Ab III and Inno-Lia HIV I/II Score, respectively. The seropositivity rates for HBsAg, anti-HCV, and anti-HIV-1/2 were determined as 1.76%, 0.07%, and 0.008%, respectively. Compared to the previously published data from Red Crescent Centers in Turkey, it was found that HBV and HCV seroprevalances decreased and HIV seroprevalance increased in recent years. In conclusion, we believe that the drop in HBV and HCV prevalence rates are likely multifactorial and may have resulted from more diligent donor questioning upon screening, a higher level of public awareness on viral hepatitis as well as the expansion of HBV vaccination coverage in Turkey. Another factor to contribute to the decreased prevalence of HCV stems from the use of more sensitive confirmation testing on all reactive results, thereby eliminating a fair amount of false positive cases. Despite similar transmission routes, the increase in HIV prevalence in contrast to HBV and HCV may be linked to the increase in AIDS cases in Turkey in recent years.

The prevalence of hepatitis B virus (HBV, hepatitis C virus (HCV, human immunodeficiency virus (HIV, and syphilis infections were expressed in percentages for the entire study group as well as groups by demographic characteristics and donation frequency, with differences analyzed using Fisher's exact or Chi-square test. Logistic regression was performed to identify the influencing factors of the detected results. RESULTS: 1,769 (2.67%, 95% CI 2.55-2.79% of the donated blood had serological evidence of infection with at least one pathogen and 44 (0.07%, 95% CI 0.05-0.09% showed evidence of multiple infections. The seroprevalence of HBV, HCV, HIV, and syphilis infections was 0.87% (95% CI 0.80-0.94%, 0.86% (95% CI 0.79-0.93%, 0.31% (95% CI 0.26-0.35%, and 0.70% (95% CI 0.64-0.76% respectively. Trend analysis for the prevalence of TTIs showed a significant increase from 2.44% to 3.71% (χ2 = 100.72, p = 0.00 over this 6-year period. The positive rates for TTIs varied along demographic lines. The top three risk factors in test-positive donors were identified as age, education level and donation frequency. The older age group and lower educated group were linked to a higher prevalence of TTIs. A decreasing prevalence was associated with an increasing frequency of blood donations (χ2 = 562.78, p = 0.00. CONCLUSIONS: Hepatitis B and C were found most, and often in conjunction with syphilis. These were the primary threats to blood safety. The high positivity rate and the increasing prevalence of TTIs among blood

  17. Degeneration and atrophy of the thymus of lethally irradiated dogs, rescued by transfusion of cryopreserved autologous blood leukocytes

    International Nuclear Information System (INIS)

    Dogs exposed to a fatal radiation dose of 12 Gy were rescued by transfusion of autologous blood leukocytes. A severe acute and long-lasting damage to the thymus was observed. The acute damage, as observed on the tenth day, consisted of a marked reduction in the number of lymphocytes, degeneration of Hassall's bodies, and hemorrhage. Long-term effects, observed several months after irradiation, were partial to total atrophy of the thymus. Regeneration, when it occurred, was limited to a few small isolated areas in which lymphopoiesis was supported by epithelial reticular cells. In contrast, the lymph nodes of all dogs had abundant cortical lymphopoiesis. The abundant hemopoiesis present in the marrow from the tenth day after irradiation until the end of the observation period should have provided sufficient circulating precursor cells to seed the thymus and regenerate the organ to the same extent as that observed in the other blood-forming organs. The impairment of lymphopoietic regeneration in the thymus seems to be due, therefore, to damage caused by irradiation on the specific stroma of the organ, which is not able to support such activity

    Blood components have been in use in clinical practice for many decades now. In spite of fairly clear guidelines regarding their use, inappropriate prescriptions for components are still rampant. We undertook this work to assess the appropriateness of fresh frozen plasma (FFP) transfusions in our hospital. A prospective audit of 504 transfusion orders for 1761 FFP units was conducted over a 6-month period which was followed by a re-audit of 294 FFP prescriptions for 961 units. In the initial audit, we identified 304 (60.3%) prescriptions which were inappropriate according to the British Committee for Standardization in Hematology (BCSH) guidelines. The re-audit performed after an educational campaign among clinicians showed a reduction in inappropriate requests by 26.6%. The specific areas of misuse were FFP transfusions in patients with hypoproteinaemic states (40.5%), anaemia (36.5%), bleeding without coagulation factor deficiency (10.2%) and volume depletion (9.2%). A significant 50.3% of requests in the initial audit and 38.4% in the re-audit were for single- or two-unit transfusions, which were subtherapeutic. FFP transfusions carry the same risks to the patients as any other blood component. Prescribers of these transfusions need to be aware of the clinical setting where their use is appropriate. Local hospital transfusion committees can play a vital role in overseeing transfusion practices to ensure optimal use of blood/component therapy. PMID:15180815

    2016-06-01

    Pathogen inactivation technologies represent a shift in blood safety from a reactive approach to a proactive protective strategy. Commercially available technologies demonstrate effective killing of most viruses, bacteria, and parasites and are capable of inactivating passenger leukocytes in blood products. The use of pathogen inactivation causes a decrease in the parameters of products that can be readily measured in laboratory assays but that do not seem to cause any alteration in hemostatic effect of plasma or platelet transfusions. Effort needs to be made to further develop these technologies so that the negative quality impact is ameliorated without reducing the pathogen inactivation effectiveness. PMID:27112999

    Therapeutic and diagnostic applications of nanomedicine are playing increasingly important roles in human health. Various types of synthetic nanoparticles, including liposomes, micelles, and other nanotherapeutic platforms and conjugates, are being engineered to encapsulate or carry drugs for treating diseases such as cancer, cardiovascular disorders, neurodegeneration, and inflammations. Nanocarriers are designed to increase the half-life of drugs, decrease their toxicity and, ideally, target pathological sites. Developing smart carriers with the capacity to deliver drugs specifically to the microenvironment of diseased cells with minimum systemic toxicity is the goal. Blood cells, and potentially also the liposome-like micro- and nano-vesicles they generate, may be regarded as ideally suited to perform such specific targeting with minimum immunogenic risks. Blood cell membranes are "decorated" with complex physiological receptors capable of targeting and communicating with other cells and tissues and delivering their content to the surrounding pathological microenvironment. Blood cells, such as erythrocytes, have been developed as permeable carriers to release drugs to diseased tissues or act as biofactory allowing enzymatic degradation of a pathological substrate. Interestingly, attempts are also being made to improve the targeting capacity of synthetic nanoparticles by "decorating" their surface with blood cell membrane receptor-like biochemical structures. Research is needed to further explore the benefits that blood cell-derived microvesicles, as a Trojan horse delivery systems, can bring to the arsenal of therapeutic micro- and nanotechnologies. This short review focuses on the therapeutic roles that red blood cells and platelets can play as smart drug-delivery systems, and highlights the benefits that blood transfusion expertise can bring to this exciting and novel biomedical engineering field.

    For many years, transfusion of allogeneic red blood cells, platelet concentrates, and plasma units has been part of the standard therapeutic arsenal used along the surgical and nonsurgical treatment of patients with malignancies. Although the benefits of these blood products are not a matter of debate in specific pathological conditions associated with life-threatening low blood cell counts or bleeding, increasing clinical evidence is nevertheless suggesting that deliberate transfusion of these blood components may actually lead to negative clinical outcomes by affecting patient's immune defense, stimulating tumor growth, tethering, and dissemination. Rigorous preclinical and clinical studies are needed to dimension the clinical relevance, benefits, and risks of transfusion of blood components in cancer patients and understand the amplitude of problems. There is also a need to consider validating preparation methods of blood components for so far ignored biological markers, such as microparticles and biological response modifiers. Meanwhile, blood component transfusions should be regarded as a personalized medicine, taking into careful consideration the status and specificities of the patient, rather than as a routine hospital procedure.

    In 9 dogs with severe hemorrhagic shock, the effect of hemocorrector "Lactoprotein" on the indices of coagulative hemostasis and rheologic blood properties was studied. It was established that in intravenous transfusion of lactoprotein at a dose of 10 ml/kg permitting to lead the animals out from the state of shock, the syndromes of disseminated intravascular coagulation and high viscosity of the blood were cupped off. However, by the end of 48 hours of observation, fibrinogen level in the blood of the animals increased sharply, while antithrombin-III concentration and hematocrit decreased. Together with recommendation to use lactoprotein in the complex of shock therapy at all the stages of medical evacuation, the conclusion about necessity to perform at the early postshock period the differential component hemo- and anticoagulative therapy has been made.

    Background Blood transfusion is considered a potential risk factor for transmission of life-threatening viral infections, including HIV, HCV and HBV infections. This study was performed to find out the prevalence and trends of these infections among blood donors in Southern Iran. Methods The blood donor data recorded in twelve regional blood transfusion centers from 2004 to 2014 were analyzed in an anonymous way with respect to the results of serological screening for HBV, HCV, and HIV infections. Overall, 293454 donors were screened for viral infections. Results Most of the donors were male, married, aged between 20–40 years, educated, and regular donors. The overall seroprevalence rates of HBV, HCV and HIV were 0.15%, 0.1% and 0.004%, respectively. The highest seroprevalence was found for HBV, followed by HCV and HIV. These infections were more prevalent in male, low educated and first time donors. The highest HCV seroprevalence was observed among donors aged 20 to 40 years, while HBV seroprevalence increased with age. The seroprevalence rates of HBV and HCV from 2004 to 2014 showed significant decreasing trends from 0.460% to 0.060% (P < 0.001) and 0.329% to 0.045% (P < 0.001), respectively. Whereas HIV infection had a slight but not significant decline from 0.0173% in 2004 to 0.0028% in 2014 (P = 0.087). Conclusions The decreasing trends of transfusion-transmissible viral infections in blood donations indicate that the attempts of IBTO were successful in improving the safety of the blood supply, since the prevalence rates of viral infections have been reduced to very low levels in blood donations over the years. However, still more effective techniques such as polymerase chain reaction (PCR) are needed to guarantee blood safety. PMID:27309959

    This study investigates a chain of HIV transmission events due to homosexual exposure and blood transfusion in China. The MiSeq platform, a next generation sequencing (NGS) system, was used to obtain genetic details of the HIV-1 env region (336 base pairs). Evolutionary analysis combined with epidemiologic evidence suggests a transmission chain from patient T3 to T2 through homosexual exposure and subsequently to T1 through blood transfusion. More importantly, a phylogenetic study suggested a likely genetic bottleneck for HIV in homosexual transmission from T3 to T2, while T1 inherited the majority of variants from T2. The result from the MiSeq platform is consistent with findings from the epidemiologic survey. The MiSeq platform is a powerful tool for tracing HIV transmissions and intrapersonal evolution.

  14. Evaluation of the effect of routine packed red blood cell transfusion in anemic cervix cancer patients treated with radical radiotherapy

    International Nuclear Information System (INIS)

    Purpose: It is well established that anemia predicts diminished radiocurability in cervix cancer. However, the therapeutic benefit of measures to correct the anemia remains controversial. The objective of this study was to determine the impact of routine transfusion in patients with hemoglobin level (hb-l) ≤11 g/dl. Methods and Materials: Since 1985, it has been departmental policy to attempt to correct hb-l ≤11 g/dl before and/or during radiotherapy by red blood cell transfusion (RBCT) in patients undergoing radical radiotherapy for primary cervix cancer. To assess the benefit of RBCT, the charts of 204 patients (FIGO: IB-IV) treated until 1997 were reviewed. Parameters analyzed for their impact on disease-specific survival (DSS), pelvic control (PC), and metastases-free survival (MFS) included pretreatment hb-l, treatment hb-l, stage, tumor size, and lymph node status. To determine any differences in outcome according to type of anemia, a separate analysis was performed, grouping patients by cause of anemia (tumor vs. other medical illness related). Results: Each of the parameters tested was significantly correlated with the end points studied in univariate analysis. Patients whose hb-l were corrected (18.5%) had an outcome that did not differ significantly from that of nontransfused patients, whereas DSS, PC, and MFS (all: p<0.001) were significantly decreased in nonresponders to RBCT. Subgroup analysis showed no impact of hb-l in patients with other medical illness-related anemia (n=12). In multivariate analysis treatment, but not pretreatment, hb-l remained predictive for DSS, PC, and MFS. Persistent anemia was associated with a significantly increased risk of death (relative risk: 2.1) and pelvic failure (relative risk: 2.4) compared with nontransfused patients. If only patients with tumor anemia were considered, the respective risks increased (2.7; 3.6). None of the patients with other causes of anemia recurred, whether or not their hb-l was maintained

Durante muito tempo a transfusão de hemácias era vista como tendo benefícios clínicos óbvios. Entretanto nos últimos anos a prática de transfusão sanguínea tem sido examinada de uma forma mais cautelosa, levando a investigações a respeito dos benefícios transfusionais, incluindo aqui o fato de os efeitos imunomoduladores relacionados à transfusão podem aumentar o risco de morbimortalidade dos pacientes. OBJETIVOS: Avaliar o efeito da transfusão de concentrado de hemácias e sua relação com a produção de citocinas inflamatórias e dano oxidativo em pacientes criticamente enfermos admitidos em uma unidade de terapia intensiva. MÉTODOS: Foram analisados durante 6 meses, no ano de 2008, pacientes internados na unidade de terapia intenvia que realizaram transfusão de concentrado de hemácias. Foram analisados os níveis séricos pré e pós transfusionais de interleucina-6 (IL-6, proteínas carboniladas e substâncias reativas ao ácido tiobarbitúrico (TBARS. RESULTADOS: Houve diminuição dos níveis séricos de IL-6 pós-transfusionais e um aumento significativo tanto para TBARS quanto para proteínas carboniladas. No entanto não houve significância estatística entre os níveis séricos de IL-6, TBARS antes e após transfusão de concentrado de hemácias e a taxa de mortalidade. Contudo ocorreu significância da relação dos níveis pós transfusionais de proteínas carboniladas e mortalidade.

    Although often a life-saving therapeutic maneuver, there is minimal data available that details the effects of intraoperative packed red blood cell transfusion (IOT) after microvascular free tissue transfer. The National Surgical Quality Improvement Program database was queried to identify all patients who underwent microvascular free tissue transfer between 2006 and 2010. Multivariate logistic regression models were used to determine the association between intraoperative transfusion and outcomes. Upon bivariate and multivariate analyses, IOT was significantly associated with higher rates of overall complications (odds ratio [OR], 2.02; 95% confidence interval [CI], 1.12-3.63), medical complications (OR, 3.35; 95% CI, 1.75-6.42), postoperative transfusion (OR, 6.02; 95% CI, 2.02-17.97), and reoperation (OR, 2.24; 95% CI, 1.24-4.04). IOT was not associated with either surgical complications or free flap loss. IOT significantly increases risk for adverse overall and medical complications. However, IOT was not associated with surgical complications or free flap loss. Transfusion practices in the operating room should be reevaluated to improve overall outcomes. PMID:24114710

The prevalence appeared to be higher in younger age group (17-30 yrs. Only 16.6% cases should be patients returned with results of the confirmatory tests for HIV and were found positive. CONCLUSION: Hepatitis-B and C sero-prevalence in our series of replacement donors appears high compared to most studies from neighboring countries and relatively low in comparison to earlier studies from Pakistan. Prevalence of HIV, however, appears low and turn out of HIV positive cases for confirmatory tests is low.

    Transfusion of blood products is a cornerstone in managing many critically ill children. Major improvements in blood product safety have not diminished the need for caution in transfusion practice. In this review, we aim to discuss the interplay between benefits and potential adverse effects of...... transfusion in critically ill children by including 65 papers, which were evaluated based on previously agreed selection criteria. Current practice on transfusing critically ill children is mainly founded on the basis of adult studies, common practices with cut-off values, and expert opinions, rather than...... evidence-based medicine. Paediatric patients have explicit physiological challenges and requirements to be addressed. Critically ill children often suffer from anaemia, have substantial iatrogenic blood loss with subsequent transfusions, and are at a higher risk of complications, often due to human errors...

    Full Text Available Abstract Background Platelet transfusion is universally employed in acute leukemia. Platelet concentrate supernatants contain high concentrations of biologic mediators that might impair immunity. We investigated whether washed platelet and red cell transfusions could improve clinical outcomes in adult patients with acute leukemia. Methods A pilot randomized trial of washed, leukoreduced ABO identical transfusions versus leukoreduced ABO identical transfusions was conducted in 43 adult patients with acute myeloid or lymphoid leukemia during 1991–94. Primary endpoints to be evaluated were platelet transfusion refractoriness, infectious and bleeding complications and overall survival. Results There were no significant differences in infectious or major bleeding complications and only one patient required HLA matched platelet transfusions. Minor bleeding was more frequent in the washed, leukoreduced arm of the study. Confirmed transfusion reactions were more frequent in the leukoreduced arm of the study. Overall survival was superior in the washed arm of the study (40% versus 22% at 5 years, but this difference was not statistically significant (p = 0.36. A planned subset analysis of those ≤50 years of age found that those in the washed, leukoreduced arm (n = 12 had a 75% survival at five years compared with 30% in the leukoreduced arm (n = 10 (p = 0.037 Conclusion This study provides the first evidence concerning the safety and efficacy of washed platelets, and also raises the possibility of improved survival. We speculate that transfusion of stored red cell and platelet supernatant may compromise treatment, particularly in younger patients with curable disease. Larger trials will be needed to assess this hypothesis.

    The purpose of this study was to evaluate the effectiveness of early treatment with erythropoietin (EPO) in two different treatment regimes (high vs. low dose) in comparison to the conventional treatment of packed red blood cell (PRBC) transfusions in the management of anaemia of prematurity in a country with limited resources. An open controlled trial was conducted on 93 preterm infants (7 days postnatal age, 900-1500 g birthweight). Patients were randomly assigned either to a low dose (250 IU/kg), a high dose (400 IU/kg), or a control group. EPO was administered subcutaneously three times a week and all infants received 6 mg/kg iron orally from study entry to endpoint of therapy. Haematological parameters were measured and compared. The success was defined as an absence of transfusions and a haematocrit that did not fall below 30 per cent during the time period that the infants were in the study. The three groups were statistically comparable at study entry with respect to gestational age, birthweight, Apgar scores, and haematological values. Over the period that the infants were in the study, 75 per cent of the low dose group and 71 per cent of the high dose group met the criteria for success compared with 40 per cent in the control group (p < 0.001). However, there was no significant difference in the number of transfusions when the low and high EPO dose groups (9.5 per cent) were combined and compared with the control group (26.7 per cent) p = 0.0587. It was concluded that in stable infants, 900-1500 g, where phlebotomy losses are minimized and stringent transfusion guidelines are adhered to, EPO does not significantly decrease the number of transfusions. A conservative approach in the management of anaemia of prematurity, is a viable alternative in areas with limited resources. PMID:12200985

    In this presented study, we have developed a photochemical model of cerebral in farction in rabbit with stable and reproducible infarct size and extent. This model is similar to the pathological changes in human cerebral infarction. Using this model, therapeutic effects and mechanisms of UOBT on brain ischemic injury were invetigated in rabbits following the photochemical infarcnon The results showed that UOBT could significantly reduce the mtarcted size, and improve the cerebral blood flow compared with the control animals treated with non-u-radiated ad non-oxygenated blood transfusion. These data suggest that the UOBT may have a therapeutic potential for clinical rehabilitation effect in stroke treatment

    Current recommendations vary with regard to the frequency of change of a red blood cell (RBC) administration set. A full review was undertaken to evaluate the recommendations for how often a RBC administration set should be changed while a patient is being transfused. Comprehensive searches of Medline, Embase, Cinahl, the Cochrane Library, handsearching of transfusion journals, guidelines and websites and contact with administration set manufacturers identified 32 relevant papers: 11 clinical updates; 11 guidelines; 5 manufacturer data sheets; 3 standards; 1 Department of Health report and 1 expert opinion. Recommendations varied widely across papers. There was no pattern in recommendation by paper type, date or country of origin. Recommendations were based on change of RBC administration set either after a given number of hours or number of RBC units. The recommendations varied widely and ranged from 4 to 48 h and from 'every unit' to 'several units'. The most frequent recommendations were change of RBC administration set after 12 h or 4 units. Methodological quality of the included papers is poor. There is no formal evidence base on which to support current recommendations or challenge the current British Committee for Standards in Haematology guideline. Targeted research aimed at establishing an evidence base may be warranted and would need to document other variables that can impact frequency of change, including type of filter, age of blood and duration of RBC transfusion.

    Full Text Available Background: Potential deleterious effects of red blood cell (RBC transfusions, especially from blood kept at length, have been ascribed to biochemical changes during storage, including those of nitric oxide (NO metabolism. Study methods and design: In this study, NO metabolites, nitrite and nitrate, were quantified in RBCs and whole blood with time of storage. Whole blood (WB, leukoreduced (LR, and non-leukoreduced (NLR components were obtained from healthy volunteer donors and stored in polyvinyl chloride bags for 42 days. Nitrite and nitrate were measured using reductive gas-phase chemiluminescence. Results: Nitrite concentrations initially decreased rapidly from about 150nmol/L, but stabilized at about 44nmol/L in room air for up to 42 days. Nitrate concentrations remained stable during storage at about 35µmol/L. Cells from bags maintained in an argon chamber showed decreased nitrite levels compared to those maintained in room air. Inhibition of enzymes implicated in the NO cycle did not alter nitrite levels. Conclusion: As erythrocytes may contribute to the control of blood flow and oxygen delivery through reduction of nitrite to NO under hypoxic conditions, the present findings provide insight into possible effects of blood transfusion. These measurements may explain some adverse effects of RBC transfusion and suggest ways of optimizing the preservation of stored blood.

    Full Text Available Background: The laboratory request form (LRF is a communication link between laboratories, requesting physicians and users of laboratory services. Inadequate information or errors arising from the process of filling out LRFs can significantly impact the quality of laboratory results and, ultimately, patient outcomes.Objective: We assessed routinely-submitted LRFs to determine the degree of correctness, completeness and consistency.Methods: LRFs submitted to the Department of Haematology (DH and Blood Transfusion Services (BTS of Aminu Kano Teaching Hospital in Kano, Nigeria, between October 2014 and December 2014, were evaluated for completion of all items on the forms. Performance in four quality indicator domains, including patient identifiers, test request details, laboratory details and physician details, was derived as a composite percentage.Results: Of the 2084 LRFs evaluated, 999 were from DH and 1085 from BTS. Overall, LRF completeness was 89.5% for DH and 81.2% for BTS. Information on patient name, patient location and laboratory number were 100% complete for DH, whereas only patient name was 100% complete for BTS. Incomplete information was mostly encountered on BTS forms for physician’s signature (60.8% and signature of laboratory receiver (63.5%. None of the DH and only 9.4% of BTS LRFs met all quality indicator indices.Conclusion: The level of completion of LRFs from these two departments was suboptimal. This underscores the need to review and redesign the LRF, improve on training and communication between laboratory and clinical staff and review specimen rejection practices.

    A 34-year-old woman with a diagnosis of hemophagocytic lymphohistocytosis (HLH) received a double umbilical cord blood transplantation following a myeloablative chemotherapy preparative regimen with busulfan and cyclophosphamide. HLH is a rare, potentially fatal hematologic disorder characterized by the overactivation of histocytes and T lymphocytes, leading to organ infiltration and acute illness. On day 25 post-transplantation, the patient required a platelet transfusion for a platelet count of 6,000 per ml (normal range = 150,000-450,000 per ml). The patient's blood type prior to the cord blood transplantation was B positive and, although both umbilical cord blood donors were O positive, the patient was still B positive per blood bank testing on that day. Although the recipient of an allogenic stem cell transplantation will eventually become the blood type of the donor, the time for this process to occur varies for each person. That process must be monitored by the blood bank for the purpose of cross-matching blood products to decrease hemolysis as much as possible. The patient was premedicated with the facility's standard for platelet transfusions: acetaminophen 650 mg and diphenhydramine 25 mg about 30 minutes prior to the platelet transfusion. PMID:24161631

    Full Text Available Aims: In this study we have evaluated the various adverse reactions related to transfusion occurring in our institution as a pilot institutional effort toward a hemovigilance program. This study will also help in understanding the problems faced by blood banks/Transfusion Medicine departments in implementing an effective hemovigilance program. Materials and Methods: All the adverse reactions related to transfusion of whole blood and its components in various clinical specialties were studied for a period of 1 year. Any transfusion-related adverse event was worked up in accordance with guidelines laid down by the Directorate General of Health Services (DGHS and departmental standard operating procedures. Results: During the study period from November 1, 2011 to October 31, 2012, 45812 components were issued [30939 WB/PRBC; 12704 fresh frozen plasma (FFP; 2169 platelets]. Risk estimation per 1000 units of red cells (WB/PRBC transfused was estimated to be: 0.8 for febrile nonhemolytic transfusion reaction (FNHTR, 0.7 for allergic reaction, 0.19 for acute hemolytic transfusion reaction (AcHTR, 0.002 for anaphylactoid reactions, 0.1 for bacterial sepsis, and 0.06 for hypervolemia and hypocalcemia. 0.09 is the risk for delayed transfusion reaction and 0.03 is the risk for transfusion-related acute lung injury (TRALI. Risk estimate per 1,000 units of platelets transfused was estimated to be 1.38 for FNHTR, 1.18 for allergic reaction, and 1 in case of bacterial sepsis. Risk estimation per 1,000 units of FFP was estimated to be 0.15 for FNHTR and 0.2 for allergic reactions. Conclusions: Factors such as clerical checks at various levels, improvement in blood storage conditions outside blood banks, leukodepletion, better inventory management, careful donor screening, bedside monitoring of transfusion, and documentation of adverse events may decrease transfusion-related adverse events. Better coordination between transfusion specialists and various clinical

The frequencies of ATRs and the associated symptoms, reported by the sentinel sites of the Ontario Transfusion Transmitted Injuries Surveillance System from 2008 to 2012, illustrate an overlap in presenting symptoms. Despite this complexity, the differential diagnosis of an ATR can be determined by considering predominant signs or symptoms, such as fever, dyspnea, rash, and/or hypotension, as these signs and symptoms guide further investigations and management. Reporting of ATRs locally and to hemovigilance systems enhances the safety of the blood supply. Challenges to the development of an international transfusion reaction reporting system are discussed, including the issue of jurisdiction and issues of standardization for definitions, investigations, and reporting requirements. This review discusses a symptom-guided approach to the differential diagnosis of ATRs, the evolution of hemovigilance systems, an overview of the current Canadian system, and proposes a best practice model for hemovigilance based on a World Health Organization patient safety framework.

    Critical bleeding (CB) requiring massive transfusion (MT) can occur in a variety of clinical contexts and is associated with substantial mortality and morbidity. In 2011, the Australian National Blood Authority (NBA) published patient blood management guidelines for CB and MT, which found limited high-quality evidence from which only 2 recommendations could be made. The aim of this systematic review (SR) was to update these guidelines and identify evidence gaps still to be addressed. A comprehensive search was performed for randomized controlled trials (RCTs) and SRs using MeSH index and free text terms in MEDLINE, the Cochrane Library (Issue 11, 2012), EMBASE, CINHAL, PUBMED, and the Transfusion Evidence Library up to July 15, 2014. The evidence was grouped according to 4 questions based on the original guideline relating to transfusion interventions: (1) effect of dose, timing, and ratio of red blood cells (RBCs) to component therapy on patient outcomes; (2) effect of RBC transfusion on patient outcomes; (3) effect of fresh frozen plasma, platelet, cryoprecipitate, fibrinogen concentrate, and prothrombin complex concentrate on patient outcomes; and (4) effect of recombinant activated factor VII (rFVIIa) on patient outcomes. From this search, 19 studies were identified: 6 RCTs and 13 SRs. Two of the RCTs were pilot/feasibility studies, 3 were investigating rFVIIa, and 1 compared restrictive versus liberal RBC transfusion in upper gastrointestinal hemorrhage. Overall, limited new evidence was identified and substantial evidence gaps remain, particularly with regard to the effect of component therapies, including ratio of RBC to component therapies, on patient outcomes. Clinical trials to address these questions are required. PMID:25716645

    A retrospective analysis was conducted on 20 D(-) liver transplant (LT) recipients transfused with D(+) RBCs perioperatively and screened for RBC antibodies between 2 and 6 months later. None developed anti-D detectable by the indirect antiglobulin test. Two patients produced weak anti-D that reacted only with papain-treated RBCs at 10 and 11 days without any sign of immune haemolysis. Antibodies became quickly undetectable. These data suggest an unusual pattern of alloimmunization in LT recipients with rapid, weak and transient antibody response and support the safety of transfusing D(+) RBCs in most of D(-) patients during LT surgery.

    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. Structurally, MPs have a bilayered phospholipid structure exposing coagulant-active phosphatidylserine and expressing various membrane receptors, and they serve as cell-to-cell shuttles for bioactive molecules such as lipids, growth factors, microRNAs, and mitochondria. It was established that ex vivo processing of blood into its components, involving centrifugation, processing by various apheresis procedures, leucoreduction, pathogen reduction, and finally storage in different media and different types of blood bags, can impact MP generation and content. This is mostly due to exposure of the collected blood to anticoagulant/storage media and due to shear stresses or activation, contact with artificial surfaces, or exposure to various leucocyte-removal filters and pathogen-reduction treatments. Such artificially generated MPs, which are added to the original pool of MPs collected from the donor, may exhibit specific functional characteristics, as MPs are not an inert element of blood components. Not surprisingly, MPs' roles and functionality are therefore increasingly seen to be fully relevant to the field of transfusion medicine, and as a parameter of blood safety that must be considered in haemovigilance programmes. Continual advancements in assessment methods of MPs and storage lesions are gradually leading to a better understanding of the impacts of

    Biochemical investigations on the regulatory mechanisms of red blood cell (RBC) and platelet (PLT) metabolism have fostered a century of advances in the field of transfusion medicine. Owing to these advances, storage of RBCs and PLT concentrates has become a lifesaving practice in clinical and military settings. There, however, remains room for improvement, especially with regard to the introduction of novel storage and/or rejuvenation solutions, alternative cell processing strategies (e.g., pathogen inactivation technologies), and quality testing (e.g., evaluation of novel containers with alternative plasticizers). Recent advancements in mass spectrometry-based metabolomics and systems biology, the bioinformatics integration of omics data, promise to speed up the design and testing of innovative storage strategies developed to improve the quality, safety, and effectiveness of blood products. Here we review the currently available metabolomics technologies and briefly describe the routine workflow for transfusion medicine-relevant studies. The goal is to provide transfusion medicine experts with adequate tools to navigate through the otherwise overwhelming amount of metabolomics data burgeoning in the field during the past few years. Descriptive metabolomics data have represented the first step omics researchers have taken into the field of transfusion medicine. However, to up the ante, clinical and omics experts will need to merge their expertise to investigate correlative and mechanistic relationships among metabolic variables and transfusion-relevant variables, such as 24-hour in vivo recovery for transfused RBCs. Integration with systems biology models will potentially allow for in silico prediction of metabolic phenotypes, thus streamlining the design and testing of alternative storage strategies and/or solutions.

    Delayed serological transfusion reaction (DSTR) is defined as absence of clinical signs of hemolysis and demonstration of new, clinically-significant antibodies against red blood cells after a transfusion, by either positive direct antiglobulin test or positive antibody screen with newly identified RBC alloantibody. Various delayed hemolytic transfusion reaction cases are reported after red cell transfusions. However, the incidence of DSTR after platelet transfusion due to non-Rh(D) antibodies is not much documented. We report here a case of DSTR due to anti-e Rh antibody in a multiply red cell alloimmunized female patient after single donor platelets transfusion. PMID:27408414

    Full Text Available Abstract Background Aprotinin has been shown to be effective in reducing peri-operative blood loss and the need for re-operation due to continued bleeding in cardiac surgery. The lysine analogues tranexamic acid (TXA and epsilon aminocaproic acid (EACA are cheaper, but it is not known if they are as effective as aprotinin. Methods Studies were identified by searching electronic databases and bibliographies of published articles. Data from head-to-head trials were pooled using a conventional (Cochrane meta-analytic approach and a Bayesian approach which estimated the posterior probability of TXA and EACA being equivalent to aprotinin; we used as a non-inferiority boundary a 20% increase in the rates of transfusion or re-operation because of bleeding. Results Peri-operative blood loss was significantly greater with TXA and EACA than with aprotinin: weighted mean differences were 106 mls (95% CI 37 to 227 mls and 185 mls (95% CI 134 to 235 mls respectively. The pooled relative risks (RR of receiving an allogeneic red blood cell (RBC transfusion with TXA and EACA, compared with aprotinin, were 1.08 (95% CI 0.88 to 1.32 and 1.14 (95% CI 0.84 to 1.55 respectively. The equivalent Bayesian posterior mean relative risks were 1.15 (95% Bayesian Credible Interval [BCI] 0.90 to 1.68 and 1.21 (95% BCI 0.79 to 1.82 respectively. For transfusion, using a 20% non-inferiority boundary, the posterior probabilities of TXA and EACA being non-inferior to aprotinin were 0.82 and 0.76 respectively. For re-operation the Cochrane RR for TXA vs. aprotinin was 0.98 (95% CI 0.51 to 1.88, compared with a posterior mean Bayesian RR of 0.63 (95% BCI 0.16 to 1.46. The posterior probability of TXA being non-inferior to aprotinin was 0.92, but this was sensitive to the inclusion of one small trial. Conclusion The available data are conflicting regarding the equivalence of lysine analogues and aprotinin in reducing peri-operative bleeding, transfusion and the need for re

    Full Text Available Lesão pulmonar aguda associada à transfusão (transfusion-related acute lung injury, TRALI é uma complicação clínica grave relacionada à transfusão de hemocomponentes que contêm plasma. Recentemente, TRALI foi considerada a principal causa de morte associada à transfusão nos Estados Unidos e Reino Unido. É manifestada tipicamente por dispnéia, hipoxemia, hipotensão, febre e edema pulmonar não cardiogênico, que ocorre durante ou dentro de 6 h, após completada a transfusão. Embora o exato mecanismo não tenha sido totalmente elucidado, postula-se que TRALI esteja associada à infusão de anticorpos contra antígenos leucocitários (classes I ou II ou aloantígenos específicos de neutrófilos e a mediadores biologicamente ativos presentes em componentes celulares estocados. A maioria dos doadores implicados em casos da TRALI são mulheres multíparas. TRALI, além de ser pouco diagnosticada, pode ainda ser confundida com outras situações de insuficiência respiratória aguda. Um melhor conhecimento sobre TRALI pode ser crucial na prevenção e tratamento desta severa complicação transfusional.Transfusion-related acute lung injury (TRALI is a serious clinical syndrome associated with the transfusion of plasma-containing blood components. Recently, TRALI has come to be recognized as the leading cause of transfusion-related death in the United States and United Kingdom. This complication typically presents as shortness of breath, hypoxemia, hypotension, fever and noncardiogeneic pulmonary edema, all occurring during or within 6 h after transfusion. Although the mechanism of TRALI has not been fully elucidated, it has been associated with human leukocyte antigen antibodies (class I, class II or neutrophil alloantigens and with biologically active mediators in stored cellular blood components. Most of the donors implicated in cases of TRALI are multiparous women. Rarely diagnosed, TRALI can be confused with other causes of acute

    Transfusion-dependent anemia is a common feature in a wide array of hematological disorders, including thalassemia, sickle cell disease, aplastic anemia, myelofibrosis, and myelo-dysplastic syndromes. In the absence of a physiological mechanism to excrete excess iron, chronic transfusions ultimately cause iron overload. Without correction, iron overload can lead to end-organ damage, resulting in cardiac, hepatic, and endocrine dysfunction/failure. Iron chelating agents are utilized to reduce iron overload, as they form a complex with iron, leading to its clearance. Iron chelation has been proven to decrease organ dysfunction and improve survival in certain transfusion-dependent anemias, such as β-thalassemia. Several chelating agents have been approved by the United States Food and Drug Administration for the treatment of iron overload, including deferoxamine, deferiprone, and deferasirox. A variety of factors have to be considered when choosing an iron chelator, including dosing schedule, route of administration, tolerability, and side effect profile. Deferasirox is an orally administered iron chelator with proven efficacy and safety in multiple hematological disorders. There are two formulations of deferasirox, a tablet for suspension, and a new tablet form. This paper is intended to provide an overview of iron overload, with a focus on deferasirox, and its recently approved formulation Jadenu® for the reduction of transfusional iron overload in hematological disorders.

    Full Text Available Background: Thoracic trauma occurred in 10% of the patients seen at US military treatment facilities in Iraq and Afghanistan and 52% of those patients were transfused. Among those transfused, 281 patients received warm fresh whole blood. A previous report documented improved survival with warm fresh whole blood in patients injured in combat without stratification by injury pattern. A later report described an increase in acute lung injuries after its administration. Survivorship and warm fresh whole blood have never been analyzed in a subpopulation at highest risk for lung injuries, such as patients with thoracic trauma. There may be a heterogeneous relationship between whole blood and survival based on likelihood of a concomitant pulmonary injury. In this report, the relationship between warm fresh whole blood and survivorship was analyzed among patients at highest risk for concomitant pulmonary injuries. Materials and Methods: Patients with thoracic trauma who received a transfusion were identified in the Joint Theater Trauma Registry. Gross mortality rates were compared between whole blood recipients and patients transfused with component therapy only. The association between each blood component and mortality was determined in a regression model. The overall mortality risk was compared between warm fresh whole blood recipients and non-recipients. Results: Patients transfused with warm fresh whole blood in addition to component therapy had a higher mortality rate than patients transfused only separated blood components (21.3% vs. 12.8%, P < 0.001. When controlling for covariates, transfusion of warm fresh whole blood in addition to component therapy was not associated with increased mortality risk compared with the transfusion of component therapy only (OR 1.247 [95% CI 0.760-2.048], P = 0.382. Conclusion: Patients with combat related thoracic trauma transfused with warm fresh whole blood were not at increased risk for mortality compared to

    Full Text Available Aim: This study was designed to analyze the incidence and spectrum of adverse effects of blood transfusion so as to initiate measures to minimize risks and improve overall transfusion safety in the institute. Materials and Methods: During the period from July 2002 to July 2003 all the adverse events related to transfusion of blood and blood components in various clinical specialties were recorded. They were analyzed and classified on the basis of their clinical features and laboratory tests. Attempt was also made to study the predisposing risk factors. Results: During the study period 56,503 blood and blood components were issued to 29,720 patients. A total of 105 adverse reactions due to transfusion were observed during the study period. A majority of the adverse reactions was observed in hemato-oncology patients 43% (n = 45 and in presensitized patient groups 63% (n = 66. FNHTR 41% (n = 43 and allergic reactions 34% (n = 36 were the most common of all types of adverse transfusion reactions, followed by AcHTR 8.56% (n = 9. Majority of these AcHTR were due to unmonitored storage of blood in the refrigerator of wards resulting in hemolysis due to thermal injury. Less frequently observed reactions were anaphylactoid reactions (n = 4, bacterial sepsis (n = 4, hypervolemia (n = 2, hypocalcemia (n = 2, TRALI (n = 1, DHTR (n = 1, and TAGvHD (n = 1. Conclusion: Analysis of transfusion-related adverse outcomes is essential for improving safety. Factors such as improvement of blood storage conditions outside the blood bank, improvement in cross-matching techniques, careful donor screening, adherence to good manufacturing practices while component preparation, bedside monitoring of transfusion, and documentation of adverse events will help in reducing transfusion-related morbidity and mortality.

    Background: Increased costs and mortality associated with inappropriate blood transfusions have led to investigations about blood request and blood transfusion techniques. We investigated the transfusion status in patients who underwent orthopedic surgery in Poursina Hospital (Rasht, Iran) to optimizing blood usage and determine if a scheduled transfusion program for every orthopedic surgery could improve blood transfusion management. Method: In this descriptive-prospective study, all orthopedic surgeries in Poursina Hospital, Rasht, between April to June 2013 were reviewed. All patient information was recorded, including: demographics, type of surgery, hemoglobin level, cross-match test, duration of surgery, and blood loss, and transfusion. Based on the one-way ANOVA and independent samples test analysis, cross-match to transfusion ratio and transfusion possibility, the transfusion index, and maximal surgical blood order schedule were calculated to determine blood transfusion status. Results: Among 872 selected orthopedic surgery candidates, 318 of them were cross-matched and among those, 114 patients received a blood transfusion. In this study, the cross-match to transfusion ratio was 6.4, transfusion possibility 36.47%, transfusion index 0.6, and maximal surgical blood order schedule 0.9. Conclusion: We found that blood ordering was moderately higher than the standard; so it is highly recommended to focus on the knowledge of evidence based on transfusion and standard guidelines for blood transfusion to avoid over-ordering.

    Clinical trials have provided guidance in developing triggers for transfusing in the hemodynamically stable patient. These studies have identified that improved outcomes can be obtained in the massively transfused patient when platelets and fresh frozen plasma are transfused with packed red blood cells. Studies that characterize the complications of transfusions, such as transfusion-related acute lung injury and poor cancer-related outcomes, are discussed. Emerging data that characterize the risk factors associated with transfusion-related acute lung injury and suggest metastasis and local recurrence occur at a higher rate in the transfused patient are discussed. Hematologic disorders commonly encountered by surgeons are discussed. PMID:25814112

    The administration of blood products is strictly regulated. Several weeks before the operation the preparation for transfusion begins with optimizing the patient's hematological and hemostaseological situation. In elective surgery blood group testing and antibody screening are performed soon after admission of the patient. The identification of the blood sample is important. Informed consent of the recipient has to be obtained. On the day before the operation a further blood sample is necessary for cross-matching if red blood cells are to be transfused. Usually blood products are issued for immediate administration. Before transfusion begins the blood product has to be checked, the identity of the patient must be controlled and in the case of red blood cell transfusions the AB0 bedside test has to be performed.

    Red blood cell (RBC) antibodies can persist for decades or decrease quickly to undetectable levels. Antibody persistence has not been systematically studied. Women whose children are treated with intrauterine transfusions (IUT) for haemolytic disease of the fetus (HDFN) often produce additional antibodies, which can be evoked by the intrauterine transfusion or by fetomaternal haemorrhage during the procedure. Factors associated with persistence of both the antibodies responsible for HDFN and additional antibodies were studied in 260 women whose children were treated with IUT between 1988 and 2008. They possessed 499 (205 anti-D and 294 non-D) antibodies after the last IUT. After a median follow-up of 8·7 years, all 260 antibodies primarily responsible for HDFN had persisted. Additional antibodies directed against antigens of the children persisted in 70·6%, and in 32·3% if they were not child-specific (P < 0·001). Antibodies induced by irradiated IUT persisted in only 7·1%. Multivariate analyses showed that non-HDFN antibody persistence was dependent on the antibody titre and specificity. In conclusion, persistence of antibodies mainly depends on antibody strength and specificity. Difference between fetal or non-fetal immunogens suggests maintenance of antigenic stimulation possibly by long-term fetomaternal chimerism. PMID:25244566

    Full Text Available Although increased prevalence of transfusion transmissible infections (TTI among "men who have sex with men" (MSM has been well documented, the exclusion of MSM as blood donors is contested. The aim of this systematic review is to find studies that describe the risk of TTI in MSM blood donors.We searched MEDLINE, Embase, The Cochrane Central Register of Controlled Trials, Cinahl, and Web of Science, and used GRADE for determining evidence quality. We included studies comparing MSM and non-MSM blood donors (or people eligible to give blood, living in areas most relevant for our Blood Service.Out of 18 987 articles, 14 observational studies were included. Two studies directly compared MSM with non-MSM donors showing that MSM donors have a statistically significant higher risk of HIV-1 infections. In one of these studies it was shown that this was related to recent (< 12 months MSM contact. In two additional studies no evidence was shown in favour of a certain deferral period for MSM. Ten studies, applying permanent deferral for MSM, compared infected versus non-infected donors. One study found that MSM is a statistically significant risk factor for HIV-1 infection in blood donors. For other TTI such as HBV or HCV, an increased risk of infection could not be demonstrated, because the precision of the results was affected by the low numbers of donors with MSM as risk factor, or because of risk of bias in the included studies. All studies included low level evidence, because of risk of bias and imprecision of the results.High-quality studies investigating the risk of TTI in MSM who donate blood are scarce. The available evidence suggests a link between MSM blood donors and HIV-1 infection, but is too limited to be able to unambiguously/clearly recommend a certain deferral policy.

    Historically, blood transfusion has been divised, enhanced and organized by physicians. The special status of blood led to ensure that collection of blood and its components were placed under the supervision of a physician. Throughout its history, blood transfusion organization in France has established an exclusive exercise of the collection of blood and its components entrusted to doctors, thus creating the concept of "medicine of donation". This view is changing, and programmed exercise of this activity by nurses led to question about this profession perimeter, its necessary evolution, and finally about the place of physicians in blood supply.

    Although multiple critical steps are taken to minimize the risk of infection from transfusion of blood or blood products in developed countries, this risk can never be entirely eliminated. In Canada, the risks of noninfectious transfusion reactions, such as transfusion-related acute lung injury and major allergic or anaphylactic reactions, are greater than that of infection. This updated practice point provides an overview of transfusion infection risks in Canada. Infectious agents, systemic ...

    The characterization of the human blood-associated viral community (also called blood virome) is essential for epidemiological surveillance and to anticipate new potential threats for blood transfusion safety. Currently, the risk of blood-borne agent transmission of well-known viruses (HBV, HCV, HIV and HTLV) can be considered as under control in high-resource countries. However, other viruses unknown or unsuspected may be transmitted to recipients by blood-derived products. This is particularly relevant considering that a significant proportion of transfused patients are immunocompromised and more frequently subjected to fatal outcomes. Several measures to prevent transfusion transmission of unknown viruses have been implemented including the exclusion of at-risk donors, leukocyte reduction of donor blood, and physicochemical treatment of the different blood components. However, up to now there is no universal method for pathogen inactivation, which would be applicable for all types of blood components and, equally effective for all viral families. In addition, among available inactivation procedures of viral genomes, some of them are recognized to be less effective on non-enveloped viruses, and inadequate to inactivate higher viral titers in plasma pools or derivatives. Given this, there is the need to implement new methodologies for the discovery of unknown viruses that may affect blood transfusion. Viral metagenomics combined with High Throughput Sequencing appears as a promising approach for the identification and global surveillance of new and/or unexpected viruses that could impair blood transfusion safety.

    Full Text Available Mark T Friedman,1 Peyman Bizargity,1 Sandra Gilmore,2 Arnold Friedman3 1Blood Bank and Transfusion Medicine Service, Department of Pathology, Mount Sinai St Luke's–Roosevelt Hospital Center, 2Patient Blood Management Program, Center for Blood Management and Bloodless Medicine and Surgery, Mount Sinai Beth Israel Medical Center, 3Department of Obstetrics, Gynecology, and Reproductive Science, Icahn School of Medicine at Mount Sinai, New York, NY, USA Abstract: Patients may have differing perceptions about blood transfusions based on their backgrounds, values, education levels, or cultural or religious beliefs, which may or may not be accurate. Unfortunately, despite the fact that transfusions are associated with a number of infectious and noninfectious risks, and in spite of the fact that there are ethical, accreditation, and regulatory requirements to provide information regarding transfusion risks, benefits, and alternatives to patients, transfusion consent remains inconsistently obtained. This can partly be attributed to the fact that clinicians may take on a paternalistic approach to transfusion decisions as well as to the fact that many clinicians have knowledge gaps in transfusion medicine that prevent them from obtaining transfusion consent adequately. As a result, unlike the case with other medical and surgical therapies, most patients are not included in the making of informed decisions regarding the need for transfusion versus alternative therapies, leading to many situations in which the transfusions provide little benefit to them. Recently however, a number of organizations, such as the American Association of Blood Banks and The Joint Commission in the US, have promoted multidisciplinary, evidence-based treatment strategies that aim to minimize the need for blood transfusion, the so-called patient blood management (PBM protocols. PBM strategies are expected to improve blood utilization through optimization of patients who may need

  10. Replacing the Transfusion of 1–2 Units of Blood with Plasma Expanders that Increase Oxygen Delivery Capacity: Evidence from Experimental Studies

    Full Text Available At least a third of the blood supply in the world is used to transfuse 1–2 units of packed red blood cells for each intervention and most clinical trials of blood substitutes have been carried out at this level of oxygen carrying capacity (OCC restoration. However, the increase of oxygenation achieved is marginal or none at all for molecular hemoglobin (Hb products, due to their lingering vasoactivity. This has provided the impetus for the development of “oxygen therapeutics” using Hb-based molecules that have high oxygen affinity and target delivery of oxygen to anoxic areas. However it is still unclear how these oxygen carriers counteract or mitigate the functional effects of anemia due to obstruction, vasoconstriction and under-perfusion. Indeed, they are administered as a low dosage/low volume therapeutic Hb (subsequently further diluted in the circulatory pool and hence induce extremely small OCC changes. Hyperviscous plasma expanders provide an alternative to oxygen therapeutics by increasing the oxygen delivery capacity (ODC; in anemia they induce supra-perfusion and increase tissue perfusion (flow by as much as 50%. Polyethylene glycol conjugate albumin (PEG-Alb accomplishes this by enhancing the shear thinning behavior of diluted blood, which increases microvascular endothelial shear stress, causes vasodilation and lowering peripheral vascular resistance thus facilitating cardiac function. Induction of supra-perfusion takes advantage of the fact that ODC is the product of OCC and blood flow and hence can be maintained by increasing either or both. Animal studies suggest that this approach may save a considerable fraction of the blood supply. It has an additional benefit of enhancing tissue clearance of toxic metabolites.

    Full Text Available Transfusion-related acute lung injury (TRALI is a serious clinical syndrome associated with the transfusion of plasma-containing blood components. The classic TRALI syndrome is characterized by the suddenly onset of respiratory failure within 2-6 hrs of the transfusion of a blood product, generally transient, resolves within 48-96 hrs spontaneously, and has a better prognosis. Nonetheless there is an expanded definition of TRALI syndrome up to 72 hrs, which is called delayed TRALI. The potential causes of TRALI can be explained by two distinct mechanism including the anti-leukocyte antibodies in donor plasma or in recipient plasma with the reverse mechanism, and biological response modifiers in susceptible individuals. This report highlights the succesful management of a classic TRALI case that was seen approximately two hours after the transfusion of a packed red blood cell and triggered with anti-HLA class II antibodies in the recipient with reverse mechanism accompanied by neutropenia together.

    Full Text Available The quality of platelet concentrates is an important option in transfusion therapy. pH and platelet indices have been found to be valuable parameters for monitoring the in vitro quality of platelet concentrates. Platelet activation which leads to loss of its functionality has been demonstrated by changes in those two parameters. The aim of the study was to evaluate the correlation between pH and mean platelet volume (MPV in platelet concentrates in order to examine the quality of platelet concentrate. 150 units of platelet concentrates were produced by platelet reach plasma (PRP, and stored for 5 days. Then MPV and pH were analyzed by automated hematological cell counter and Ph meter respectively. Regression analysis showed that there was a significant influence of pH changes on the changes in MPV. On the other hand, increase in pH lead to decrease in MPV. Storing platelet concentrates up to 5 days may stimulate platelet activity, enhancing its size and resulted in its destruction, so the remaining platelet are those with significantly lower MPV. Also platelet activation was those with an increase in pH. As a result measurements of MPV and pH have a great potential as quality markers of platelet concentrates.

    Introduction. There is limited data evaluating physician transfusion practices in patients with acute upper gastrointestinal bleeding (UGIB). Methods. A web-based survey was sent to 500 gastroenterologists and hepatologists across Canada. The survey included clinical vignettes where physicians were asked to choose transfusion thresholds. Results. The response rate was 41% (N = 203). The reported hemoglobin (Hgb) transfusion trigger differed by up to 50 g/L. Transfusions were more liberal in hemodynamically unstable patients compared to stable patients (mean Hgb of 86.7 g/L versus 71.0 g/L; p iron to patients with UGIB who are anemic upon discharge. Conclusions. The transfusion practices of gastroenterologists in the management of UGIB vary widely and more high-quality evidence is needed to help assess the efficacy and safety of selected transfusion thresholds in varying patients presenting with UGIB.

  20. TRALI - A Less Commonly Known Complication of Transfusion

    Directory of Open Access Journals (Sweden)

    2008-01-01

    Full Text Available Transfusion Related Acute Lung Injury (TRALI has been recently recognized as one of the serious risks associated with transfusion, presenting as respiratory distress during or after transfusion of blood products. The symptoms can be confused with other transfusion-related events such as anaphylaxis, haemolysis, or circulatory overload, or with non-transfusion-related co-morbidities such as cardiac failure. TRALI varies in severity, and mortality is not uncommon. TRALI is now the leading cause of transfusion-associated mortality, even though it is probably still under-diagnosed and under-reported due to lack of awareness of its entity.
