    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

    Transfusion-related acute lung injury is the most common cause of serious morbidity and mortality associated with the transfusion of plasma-containing blood components. The syndrome can be confused with other causes of acute respiratory failure. Herein, we describe a 71-year-old man who was transfused with fresh frozen plasma due to prolonged INR, and died of what was considered as transfusion-related acute lung injury, despite treatment.

    Full Text Available Abstract Background To report a case of disseminated fusariosis with endogenous endophthalmitis in a patient with acute lymphoblastic leukemia. Transfusion-associated immune modulation secondary to platelet transfusion could play an important role in the pathophysiology of this case. Case Presentation A 9 year-old male with acute lymphoblastic leukemia complicated by pancytopenia and disseminated Intravascular coagulation was given platelet transfusion. He developed disseminated fusariosis and was referred to the ophthalmology team for right endogenous endophthalmitis. The infection was controlled with aggressive systemic and intravitreal antifungals. Conclusion Patients with acute lymphoblastic leukemia are predisposed to endogenous fungal endophthalmitis. Transfusion-associated immune modulation may further increase host susceptibility to such opportunistic infections.

    Platelet transfusion has been a vital therapeutic approach in patients with hematologic malignancies for close to half a century. Randomized trials show that prophylactic platelet transfusions mitigate bleeding in patients with acute myeloid leukemia. However, even with prophylactic transfusions, as many as 75% of patients, experience hemorrhage. While platelet transfusion efficacy is modest, questions and concerns have arisen about the risks of platelet transfusion therapy. The acknowledged serious risks of platelet transfusion include viral transmission, bacterial sepsis, and acute lung injury. Less serious adverse effects include allergic and non-hemolytic febrile reactions. Rare hemolytic reactions have occurred due to a common policy of transfusing without regard to ABO type. In the last decade or so, new concerns have arisen; platelet-derived lipids are implicated in transfusion-related acute lung injury after transfusion. With the recognition that platelets are immune cells came the discoveries that supernatant IL-6, IL-27 sCD40L, and OX40L are closely linked to febrile reactions and sCD40L with acute lung injury. Platelet transfusions are pro-inflammatory, and may be pro-thrombotic. Anti-A and anti-B can bind to incompatible recipient or donor platelets and soluble antigens, impair hemostasis and thus increase bleeding. Finally, stored platelet supernatants contain biological mediators such as VEGF and TGF-β1 that may compromise the host versus tumor response. This is particularly of concern in patients receiving many platelet transfusions, as for acute leukemia. New evidence suggests that removing stored supernatant will improve clinical outcomes. This new view of platelets as pro-inflammatory and immunomodulatory agents suggests that innovative approaches to improving platelet storage and pre-transfusion manipulations to reduce toxicity could substantially improve the efficacy and safety of this long-employed therapy.

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.

    A 39-year-old man with cholangiocarcinoma presented with fever and abdominal pain. He was hypotensive, jaundiced and had right upper quadrant tenderness. Laboratory testing showed a leucocytosis, elevated liver function tests, total bilirubin and International Normalised Ratio (INR). Given the concern for cholangitis, the patient was given antibiotics and three units of fresh frozen plasma (FFP) before biliary drain placement. After drain placement, and within 3 h of receiving blood products, the patient became tachypnoeic and hypoxic with a chest X-ray revealing new bilateral airspace disease. The rapid development of respiratory distress was determined to most likely be transfusion-related acute lung injury (TRALI). He rapidly progressed to intubation and required 100% FiO2, high positive-end expiratory pressure (PEEP) and intermittent-prone ventilation for 48 h but eventually recovered and was extubated. TRALI is an under-recognised aetiology for respiratory distress in the critically ill. Adopting a conservative transfusion strategy may prevent TRALI.

    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.

    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.

    We report a case of two consecutive episodes of acute hemolytic transfusion reactions (HTRs) due to multiple alloantibodies in a 34-yr-old man who suffered from avascular necrosis of left femoral head. He received five units of packed red blood cells (RBCs) during surgery. Then the transfusion of packed RBCs was required nine days after the surgery because of the unexplained drop in hemoglobin level. The transfusion of the first two units resulted in fever and brown-colored urine, but he received the transfusion of another packed RBCs the next day. He experienced even more severe symptoms during the transfusion of the first unit. We performed antibody screening test, and it showed positive results. Multiple alloantibodies including anti-E, anti-c and anti-Jkb were detected by antibody identification study. Acute HTRs due to multiple alloantibodies were diagnosed, and the supportive cares were done for 6 days. We suggest the antibody screening test should be included in the panel of pretransfusion tests for safer transfusion, and it is particularly mandatory for the patients with multiple transfusions, pregnant women, and preoperative patients.

    Full Text Available A 16-year-old woman with craniofacial injury developed severe acute respiratory failure under the primary reconstructive surgical procedure requiring several units of blood and plasma. A transfusion related acute lung injury (TRALI was suspected and supportive treatment was initiated. Because of the severity of symptoms, acute extracorporeal membrane oxygenation (ECMO was planned. During preparation for ECMO, a single intravenous dose, 1 g of tranexamic acid, was administered and a remarkable improvement was observed shortly thereafter. The patient was placed on ECMO for 16 hours. The further course was uncomplicated and the patient was discharged from ICU on the 6th day after admission fully and she recovered. A clinical improvement was observed in a timely fashion following the administration of tranexamic acid. The handling of a suspected TRALI and potential benefit from administration of tranexamic acid are discussed in this case report.

    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 aim of this study was to investigate which approach for serological testing of multiparous donors might be feasible and effective to reduce the risk of transfusion-related acute lung injury (TRALI). TRALI is a serious adverse event of blood transfusion. Antibodies to granulocytes and human leucocyte antigens (HLAs) are frequently detected in sera of implicated donors. These donors are often multiparous women. A general deferral of female plasma or screening strategies for leucocyte antibodies has been proposed to increase blood safety. A prospective study was initiated in 2003. Until 2006, serum samples from all female donors reporting three or more pregnancies (n = 229) were screened for the presence of antibodies against granulocytes and HLAs by immunofluorescence and agglutination tests as well as by a commercial HLA enzyme immunoassay. In total, 40% of all multiparous women were reactive in one of the assays. Twenty-nine percent of the reactive sera contained antibodies to granulocytes but not to HLAs. During the observation period, three TRALI reactions occurred in our hospital, two of which would have been prevented if the screening program had been extended to all previously pregnant donors. We conclude from these data that, not unexpectedly, the number of previous pregnancies is not a reliable indicator for the likelihood of inducing TRALI. More importantly, screening strategies for antibodies that might induce TRALI should probably not be reduced to HLA antibody screening. This finding awaits further research. PMID:19140817

    Transfusion related acute lung injury (TRALI) has become a major reported cause of severe transfusion reactions and mortality. Over the past four years significant changes have been taken in Canada in order both to improve the recognition of the risk and to decrease its incidence. An international meeting was held in April of 2004 entitled "Towards an Understanding of TRALI". As a result of the analysis and recommendations from this meeting, the Canadian Blood Services established an ongoing review committee and established a laboratory diagnostic facility to identify at risk donors and recipients. A system has been developed to identify implicated donors and exclude them from the blood donor pool. Other steps have been taken to exclude potentially high risk donors, such as previously pregnant females, from the plasma and platelet donor pool. A considerable amount of education also has been offered to clinical services in the country. This paper summarizes the definitions, categorizations of implicated donors, and the ongoing precautionary activities related to plasma products. Noted within the article are the methods used for locating and selecting data. These were primarily based on the international TRALI conference in 2004, and from ongoing discussions and information provided by the Canadian Blood Services TRALI Review Committee. No ethics referral or approval was requested, and a summary is included in the article. PMID:20041083

    Full Text Available In stage V twin–twin transfusion syndrome (TTTS, up to 50% of surviving twins die or experience permanent disabilities, likely due to acute intertwin hemorrhage resulting in sudden severe anemia of the survivor. Although fetal middle cerebral artery (MCA Doppler studies demonstrate strong correlation with fetal hemoglobin values, acute hemorrhagic events are more difficult to diagnose, and optimal timing of delivery of the survivor poses an obstetric dilemma. We report a case of newly diagnosed stage V TTTS at 28 weeks gestation, complicated by acute severe anemia diagnosed by significantly abnormal fetal MCA Doppler studies. The anemic twin was urgently delivered and is doing well without significant sequelae.

    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.

    Full Text Available BACKGROUND: Blood transfusion is imperative when treating certain patients; however, it is not risk free. In addition to the possible transmission of contagious infectious diseases, incidents can occur immediately after transfusion and at a later time. AIMS: This study aimed to examine the immediate transfusion incidents reported in a regional blood bank in the state of Minas Gerais between December 2006 and December 2009. A retrospective quantitative epidemiological study was conducted. Data were obtained from 202 transfusion incident reports of 42 health institutions served by the blood bank. Data processing and analysis were carried out using the Statistical Package for the Social Sciences (SPSS software. RESULTS: The rate of immediate transfusion incidents reported in the period was 0.24%; febrile non-hemolytic reactions were the most common type of incident (56.4%. The most frequent clinical manifestations listed in transfusion incident reports were chills (26.9% and fever (21.6%. There was a statistically significant association (p-value < 0.05 between the infusion of platelet concentrates and febrile non-hemolytic reactions and between fresh frozen plasma and febrile non-hemolytic reaction. The majority (73.3% of transfused patients who suffered immediate transfusion incidents had already been transfused and 36.5% of the cases had previous transfusion incident reports. CONCLUSIONS: Data from the present study corroborate the implementation of new professional training programs aimed at blood transfusion surveillance. These measures should emphasize prevention, identification and reporting of immediate transfusion incidents aiming to increase blood transfusion quality and safety.

    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.

  9. Concerted action of sphingomyelinase and non-hemolytic enterotoxin in pathogenic Bacillus cereus.

    Full Text Available Bacillus cereus causes food poisoning and serious non-gastrointestinal-tract infections. Non-hemolytic enterotoxin (Nhe, which is present in most B. cereus strains, is considered to be one of the main virulence factors. However, a B. cereus ΔnheBC mutant strain lacking Nhe is still cytotoxic to intestinal epithelial cells. In a screen for additional cytotoxic factors using an in vitro model for polarized colon epithelial cells we identified B. cereus sphingomyelinase (SMase as a strong inducer of epithelial cell death. Using single and double deletion mutants of sph, the gene encoding for SMase, and nheBC in B. cereus we demonstrated that SMase is an important factor for B. cereus cytotoxicity in vitro and pathogenicity in vivo. SMase substantially complemented Nhe induced cytotoxicity in vitro. In addition, SMase but not Nhe contributed significantly to the mortality rate of larvae in vivo in the insect model Galleria mellonella. Our study suggests that the role of B. cereus SMase as a secreted virulence factor for in vivo pathogenesis has been underestimated and that Nhe and SMase complement each other significantly to cause full B. cereus virulence hence disease formation.

    2007-06-01

    Full Text Available Haemodilution is a technique used to reduce perioperative homologous blood transfusions. Haemodilution is a poorly investigated technique in veterinary medicine. This article reviews haemodilution as a potential technique to reduce perioperative homologous blood transfusions. The history of haemodilution is briefly reviewed followed by the mathematical basis to haemodilution. The issue of critical oxygen delivery and its implications for haemodilution are discussed. The effects of haemodilution on the patient, including the effects on oxygen transport, blood flow and coagulation are discussed as well as the use of colloids, fluids and blood components in haemodilution. The success and failure of haemodilution in human clinical trials and experimental evidence is discussed. Some guidelines are given for the use of haemodilution in small animal patients in the perioperative setting. It appears in all likelihood that haemodilution has a limited application in cats and other small patients. Haemodilution is most beneficial when the initial haematocrit is high, a low haemodiluted haematocrit is achieved, the patients circulating volume is large and a large amount of blood was lost. It is important to avoid haemoconcentration during surgery as this increases red blood cell loss. Haemodilution is not a substitute for poor surgical technique and inadequate haemostasis intra-operatively. Intravascular volume should be maintained throughout the procedure.

  14. Transfusion practices in trauma

    2014-01-01

    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.

    Full Text Available Background: Despite strict clinical measures, there are distinct steps in transfusion process which require acute attention.The nurse is responsible for insuring that the right unit is administered to the right patient. Knowledge of risks is essential toadminister and monitor transfusions safely.Aim: This study summarizes the available data concerning transfusion adverse events and provides theoretical and technicalaspects for improving transfusion practice.Methodology: A systematic review in PubMed, MedLine and MDConsult database was conducted. The research limitsincluded English texts, referring to transfusion risks and technological means aiming at transfusion safety.Results: Blood transfusion is a medical intervention that saves lives and improves the quality of life. The regulations forensuring the availability and assuring the quality of the blood component cannot avoid transfusion errors, placing patients atrisk. Most frequent errors are attributed to practitioners involved in the clinical transfusion process. Based on reports toSerious Hazards of Transfusion (SHOT the risk of transfusion error is estimated at 1:16,500. Over the last years severalcommittees have recommended guidance for enhancing the safety of blood ordering and administration. Moreover, newtechnology like barcode on patient wristband manages to improve the performance in each step.Conclusion: Safe transfusion process depends on a series of linked processes and nurses should take specific measuresreferring to pre- and post-transfusion stage. Technological innovations could help patients in need of transfusion therapy.

    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 : To evaluate the efficacy of clofibrate in reducing total serum bilirubin levels in late pre-term neonates with non-hemolytic jaundice. Design and Setting : Double-blind, placebo-controlled, randomized trial; tertiary level neonatal unit. Materials and Methods : A randomized controlled study was carried out in the neonatal ward of Children′s Hospital, Tabriz, Iran, over a 1-year period. Sixty-eight healthy late pre-term infants readmitted with non-hemolytic hyperbilirubinemia were randomized to receive phototherapy and clofibrate (n= 35 or phototherapy and placebo (n= 33. Statistical Analysis Used : Chi-square test and independent sample ′t′ test. Results : There were no significant differences in the weight, gender, modes of delivery and age of neonates between the two groups. Similarly the mean total serum bilirubin (TSB level at the time of admission was not significantly different between the two groups [mean± SD: 19.72 ± 1.79 (95% confidence interval: 19.12-20.54 mg/dL vs. 20.05 ± 2.82 (95% confidence interval, 19.54-22.04 mg/dL, P= 0.57]. The mean TSB 48 hours after phototherapy [mean± SD: 8.06± 1.34 (95% confidence interval: 7.94-10.18 mg/dL vs.10.94 ± 2.87 (95% confidence interval: 9.92-12.16 mg/dL, P= 0.02] and the mean duration of phototherapy [mean± SD: 64.32 ± 12.48 (95% confidence interval: 60-81.6 hours vs. 87.84 ± 29.76 (95% confidence interval: 79.2-108 hours, P< 0.001] were significantly lower in the clofibrate-treated group. Conclusions : Clofibrate is an effective adjunctive drug in neonatal hyperbilirubinemia, which results in decreased TSB level and reduced duration of phototherapy in late pre-term newborns.

    Non-hemolytic transfusion reactions (NHTR) occur in up to 30% of patients receiving platelet transfusions. Premedication with acetaminophen and diphenhydramine is a common strategy to prevent NHTR, but its efficacy has not been studied. In this prospective trial, transfusions in patients receiving pre-storage leukocyte-reduced single-donor apheresis platelets (SDP) were randomized to premedication with either acetaminophen 650 mg PO and diphenhydramine 25 mg IV, or placebo. Fifty-one patients received 98 transfusions. Thirteen patients had 15 NHTR: 15.4% (8/52) in the treatment arm and 15.2% (7/46) in the placebo arm. Premedication prior to transfusion of pre-storage leukocyte reduced SDP does not significantly lower the incidence of NHTR as compared to placebo. PMID:12111764

    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.

    Background Relapse remains an obstacle to successful allogeneic haematopoietic stem cell transplantation (alIo-HSCT) for patients with acute leukaemia and no standard treatment is available. We assessed fludarabine and cytarabine with transfusion of donor haematopoietic stem cell in treating the relapse of acute leukaemia after alIo-HSCT.Methods Seven patients, median age 34 years, with relapse of acute leukaemia after alIo-HSCT received combination chemotherapy of fludarabine with cytarabine for 5 days. Five patients suffered from acute myeloid leukaemia (2 refractory) and 2 refractory acute lymphoblastic leukaemia. After the transplantation, the median relapse time was 110 days (range,38-185 days). Two days after chemotherapy, 5 patients received infusion of donor's peripheral blood stem cells, mobilized by granulocyte colony stimulating factor. No prophylactic agents of graft versus host diseases were administered.Results Six patients achieved haematopoietic reconstitution. DNA sequence analysis at day 30 after treatment identified all as full donor chimera type. The median observation time was 189 days. After the treatment, the median time for neutrophilic granulocyte value ≥0.5x109/L and for platelet value >20x109/L were 13 days (range, 10-18 days) and 15 days (range, 11-24 days), respectively. Graft versus host disease occurred in 2 patients (acute) and 3 (chronic). Five patients suffered from pulmonary fungal infection (2 died), 3 haemorrhagic cystitis and 2 cytomegalovirus viraemia. The other patients died of leukaemia related deaths. Three patients with chronic graft versus host disease who had received donor peripheral blood stem cells reinfusion have survived for 375 days, 232 days and 195 days, respectively.Conclusions Fludarabine with cytarabine plus the donor haematopoietic stem cell should be considered as an effective therapeutic regimen for relapse of acute leukaemia after alIo-HSCT.

  3. Antibody Binding Studies Reveal Conformational Flexibility of the Bacillus cereus Non-Hemolytic Enterotoxin (Nhe) A-Component

    2016-01-01

    The non-hemolytic enterotoxin complex (Nhe) is supposed to be the main virulence factor of B. cereus causing a diarrheal outcome of food poisoning. This tripartite toxin consists of the single components NheA, -B and -C all of them being necessary for maximum toxicity. In the past, research activities aiming to elucidate the mode-of-action of Nhe were mostly focused on the B- and C-component. In this study the generation of novel monoclonal antibodies (mAb) and their thorough characterization enabled the determination of key features for NheA. By the means of immunoaffinity chromatography it could be shown that NheA does not interact with -B and -C in solution. Additionally, the establishment of a highly sensitive sandwich-EIA now enables the detection of NheA in B. cereus supernatants down to 20 pg ml-1.Peptide-based epitope mapping in combination with partially deleted recombinant NheA fragments allowed the allocation of the binding regions for the three mAbs under study. Furthermore, by different EIA set-ups the conformational flexibility of NheA could be shown. For two of the antibodies under study different mechanisms of NheA neutralization were proven. Due to prevention of complete pore formation by one of the antibodies, NheA could be detected in an intermediate stage of the tripartite complex on the cell surface. Taken together, the results obtained in the present study allow a refinement of the mode-of-action for the Nhe toxin-complex. PMID:27768742

    Sharma, Sanjeev; Sharma, Poonam; Tyler, Lisa N

    2011-03-15

    Red blood cell transfusions are used to treat hemorrhage and to improve oxygen delivery to tissues. Transfusion of red blood cells should be based on the patient's clinical condition. Indications for transfusion include symptomatic anemia (causing shortness of breath, dizziness, congestive heart failure, and decreased exercise tolerance), acute sickle cell crisis, and acute blood loss of more than 30 percent of blood volume. Fresh frozen plasma infusion can be used for reversal of anticoagulant effects. Platelet transfusion is indicated to prevent hemorrhage in patients with thrombocytopenia or platelet function defects. Cryoprecipitate is used in cases of hypofibrinogenemia, which most often occurs in the setting of massive hemorrhage or consumptive coagulopathy. Transfusion-related infections are less common than noninfectious complications. All noninfectious complications of transfusion are classified as noninfectious serious hazards of transfusion. Acute complications occur within minutes to 24 hours of the transfusion, whereas delayed complications may develop days, months, or even years later.

  9. 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.

    AIM: To study effect of operation-synchronizing transfusion of apoptotic spleen cells from donor rats on acute rejection of recipient rats after liver transplantation.METHODS: Two of Wistar rats were chosen randomly for normal liver pathology control and ten of SD rats chosen randomly for liver function control as blank group (no operation). The rest of Wistar and SD rats were divided into four groups: control group (only liver transplantation),Dex group (donors receiving intraperitoneal injection of dexamethasone), SpC group (recipients receiving infusion of spleen cells of donors), Dex-SpC group (recipients receiving infusion of apoptotic spleen cells of donors),with each group except blank group, containing 10 SD rats and 10 Wistar rats, respectively. Wistar rats received liver transplantation from SD rats, in the meantime they received infusion of spleen cells of donors, which were induced by an intraperitoneal injection of dexamethasone The serum alanine transaminase (ALT), total bilirubin (T bili), liver pathological changes and survival time were analysed. Statistical analysis was carried out using SPSS 10.0 for Windows. Differences of the parametric data of ALT in means were examined by one-way ANOVA.Differences of ALT between two groups were examined by LSD. Differences of the nonparametric data of T bili in means and scores of pathology classification for acute rejection were examined by Kruskal-Willis H test. The correlations between ALT and T bili were analysed by Bivariate. Kaplan-Meier curves were used to demonstrate survival distribution. The log-rank test was used to compare the survival data.RESULTS: There were significant differences in ALT of the five groups (F= 23.164 P= 0.000), and ALT in DexSpC group was significantly higher than that in blank control, control, Dex, and SpC groups (P = 0.000), and ALT in SpC group was significantly higher than that in blank control (P = 0.000), control (P = 0.004), and Dex groups (P = 0.02).

    2014-01-01

    Full Text Available Therapy for acute leukemia in Jehovah’s Witnesses patients is very challenging because of their refusal to accept blood transfusions, a fundamental supportive therapy for this disease. These patients are often denied treatment for fear of treatment-related death. We present the first Jehovah’s Witness patient with acute myeloid leukemia (AML treated successfully with azacitidine. After achieving complete remission (CR with one course of azacitidine therapy, the patient received conventional postremission chemotherapy and remained in CR. In the case of patients who accept blood transfusions, there are reports indicating the treatment of AML patients with azacitidine. In these reports, azacitidine therapy was less toxic, including hematoxicity, compared with conventional chemotherapy. The CR rate in azacitidine-treated patients was inadequate; however, some characteristics could be useful in predicting azacitidine responders. The present case is useful for treating Jehovah’s Witnesses patients with AML and provides a clue for anti-AML therapy requiring minimum blood transfusions.

    Full Text Available The prevalence of fatal hemolytic transfusion reactions (HTRs is approximately 1:200000 per unit. Acute HTRs occur during or within 24 h after administration of a blood product. Transfusion of incompatible red blood cells (RBCs, and, more rarely, of a large volume of incompatible plasma usually are the causative agents. Delayed HTRs are caused by a secondary immune response to an antigen on the donor’s RBCs. Different mechanisms lead to intra- and extravascular hemolysis, such as complete complement activation, phagocytosis of RBCs covered with C3b by macrophages after incomplete complement activation, or destruction of RBCs covered only with IgG by direct cell to cell contact with K cells. The clinical consequences of HTRs are triggered via several pathophysiological pathways. Formation of anaphylatoxins, release of cytokines causing a systemic inflammatory response syndrome, activation of the kinin system, the intrinsic clotting cascade and fibrinolysis result in hypotension, disseminated intravascular coagulation, diffuse bleeding, and disruption of microcirculation leading to renal failure and shock. In this review, the symptoms of HTR are introduced, laboratory investigations and treatment are described, and some recommendations for prevention are given.

    Full Text Available Alloimmunisation following red cell transfusion is a complication in patients with chronic diseases requiring multiple transfusions. The aim of this study was to determine the frequency of alloimmunisation, to identify involved alloantibodies, to establish risk factors and to quantify the alloimmunisation risk in patients with acute disorders who received red cell transfusion at the Instituto Dr. José Frota from January 1999 to January 2001. Of the 5,690 recipients who received 16,547 units of red blood cells, 4,025 were men and 1,665 were women. Recipients with previous alloimmunisation or with time of hospital stay less than one week were excluded (n = 501. Red cell alloantibodies were detected in 120 recipients (2.1%: 60 men (1.49% and 60 women (3.60%. Alloimmunisation was 2.4 fold more frequent in women and 93.33% of the women were pregnant prevously. The average number of units transfused in the alloimmunised recipients was 4.68: 4.97 units in men and 4.40 units in women. In non-alloimmunised recipients the average was 2.87 units and the risk of alloimmunisation was 0.83%: 0.59% in men and 1.44% in women. The most frequent allo-antibodies were: anti-E (18.25% and anti-D (16.06% from a total of 137 allo-antibodies detected. The median time for detection of allo-antibodies was 20.88 days. The risk of alloimmunisation detected was high considering the average number of units transfused. The age of recipients and the longer life expectancy increase the probability of further transfusion requirements in this group. Our findings point out the necessity of modifications in the current medical transfusion support indication, including in patients with acute disorders in order to prevent alloimmunisation.A aloimunização eritrocitária após transfusão de concentrado de hemácias é uma complicação em pacientes com doenças crônicas que necessitam de transfusões de repetição.

    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.

  4. Formation of small transmembrane pores: An intermediate stage on the way to Bacillus cereus non-hemolytic enterotoxin (Nhe) full pores in the absence of NheA.

    2016-01-15

    The non-hemolytic enterotoxin (Nhe) of Bacillus cereus is a three-partite toxin formed of the components NheA, -B and -C. Pore formation and subsequent lysis of target cells caused by Nhe is an orchestrated process comprising three steps: (i) formation of NheB/C oligomers in solution, (ii) attachment of the oligomers to the cell membrane, (iii) binding of NheA to the oligomers. The present study aimed to characterize the properties of the NheB/C complex and the fate of the target cell upon binding. An enzyme immunoassay allowing kinetic measurements and surface plasmon resonance revealed the fast and high affinity formation of the NheB/C oligomers. The benefit of these complexes is a more stable cell binding as well as stronger and earlier cytotoxic effect. High molecular mass hetero-oligomers (620 kDa) probably consisting of one NheC and up to 15 NheB were detected by size-exclusion chromatography and on native PAGE immunoblots. Due to the NheBC application the morphology and membrane permeability of Vero cells is partly disturbed. Formation of stable transmembrane channels with a conductance of about 870 pS and a diameter of about 2 nm due to the application of NheBC could be demonstrated in lipid bilayer experiments. Thus, the NheBC complex itself has a tendency to increase the membrane permeability prior to the emergence of full pores containing also NheA.

    2016-05-01

    Full Text Available BACKGROUND Indications for transfusion include symptomatic anaemia, haemolytic anaemia, haematological malignancy, acute sickle cell crisis, and acute blood loss of more than 30 percent of blood volume, sepsis, etc. Fresh frozen plasma infusion can be used for reversal of anticoagulant effects. Platelet transfusion is indicated to prevent haemorrhage in patients with thrombocytopenia or platelet function defects. Cryoprecipitate is used in cases of hyperfibrinogenaemia, which most often occurs in the setting of massive haemorrhage or consumptive coagulopathy, factor VIII deficiency and Von Willebrand disease as an alternate to specific component therapy. Transfusion-related infections are less common than non-infectious complications. All non-infectious complications of transfusion are classified as non-infectious serious hazards of transfusion. Acute complications occur within minutes to 24 hours of the transfusion, whereas delayed complications may develop days, months or even years later. Blood transfusion can be a lifesaving procedure, but it has risks, including infectious and non-infectious complications. There is debate in the medical literature concerning the appropriate use of blood and blood products. Clinical trials investigating their use suggest that waiting to transfuse at lower haemoglobin levels is beneficial. This study will consider the indications for transfusion of blood and blood products, and will discuss common non-infectious complications associated with transfusion. Requirement of blood and blood component transfusions in children admitted in a tertiary care hospital and its related complications. OBJECTIVE To evaluate the pattern of transfusion requirement in children admitted in a tertiary care hospital and the frequency of transfusion related complications.

    Autologous blood transfusion techniques are the principal means of reducing allogeneic blood exposure. Those techniques were developed in order to prevent the risk of contamination by viruses, mainly HVB, HCV and HIV. However that risk has become so small that all studies show an exorbitant cost/efficiency ratio. Autologous blood transfusion would therefore be of no interest in terms of public health but a recent experimental study suggested a possible transmission of the BSE agent through blood. Until the matter is settled, the precaution principle means we should prefer alternative techniques to allogeneic blood whenever possible, hence a renewed interest in autologous transfusion.

    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

    Although perioperative autologous blood transfusions are associated with few side effects, transfusion reactions can occur and can be life-threatening. We report the occurrence of postoperative laryngospasm in a patient who underwent spinal anesthesia for hip surgery. The laryngospasm could not be attributed to any cause other than the autologous blood transfusion and recurred when the transfusion was restarted. Laryngospasm was successfully treated both times with positive pressure ventilation. Autologous transfusions can trigger febrile nonhemolytic transfusion reactions, which may result in airway compromise.

    2016-04-01

    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.

    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

    It is common knowledge that for modern medicine transfusion therapy represents a precious resource and an often mandatory option. It is equally known that autohemotransfusion (or autologous transfusion) provides further advantages: certainty of blood availability when necessary, absence of transfusion reactions, elimination of the risk of infections that is still associated with the traditional homologous transfusions. In its most widespread application, autotransfusion provides for the donation of one or more units of autologous blood, mostly before elective surgery. Even in obstetrics the practice of autologous blood donation with the aim of autotransfusion is finding increasing employment. However, there are still controversial aspects and the need is pointed out for more authoritative verifications as refers to the alleged innocuity to the fetus of acute maternal blood loss. The present study was performed to contribute personal experience to a better definition of the possible interactions between autologous blood donation during pregnancy and unborn child welfare. To this end, 80 term pregnant women underwent fetal heart rate electronic monitoring before, during and after the donation of one unit of autologous blood. Both during and after the phlebotomy there were no cardiotocographic signs of fetal hypo-oxygenation. Even the non stress tests performed at a distance of 24 hours and those that were periodically repeated afterwards were normal, confirming the safety of autologous predonation during pregnancy. However, the authors think that in obstetrics it is still premature to consider the experimental phase of autotransfusion as definitively exhausted. PMID:7936387

    Granulocyte rich buffy coats were transfused to infected neutropenic patients when leukapheresis donors were not available. Efficacy of transfusions was evaluated from data supplied by hospitals administering them. Buffy coats separated from ACD blood contained a mean of 4.9 X 10(8) granulocytes. Fifty-seven patients received a course consisting of a mean of 3.8 transfusions. Of these, 27 received a mean of 17.5 units per transfusion and had a survival rate of 44.4%, which was not significantly different from the 50.0% found in 30 who received a mean of 11.1 units per transfusion. No significant difference in survival rate was found between 31 patients with acute leukemia and 26 with other disorders or 38 patients with positive and 19 with negative cultures. Finally, no significant difference in survival rate was noted between patients who received a course of greater than or equal to four transfusions or less than or equal to three transfusions in any of the above groups. Survival rates were less than those generally reported following similar courses of leukapheresis units. Buffy coat transfusions consisting of a mean of approximately 17.5 units as produced during this study have therefore been shown to be not generally beneficial. The increased survival seen in some studies utilizing leukapheresis products may relate in part to the larger number of granulocytes they contained. Greater benefit from buffy coat transfusions might result if the number of granulocytes infused were increased. Evaluation of possible efficacy associated with transfusions of increased numbers of buffy coat units further enriched with granulocytes may be justified when leukapheresis donors are not available.

    Full Text Available Transfusion associated circulatory overload (TACO is an established, but grossly under diagnosed and underreported complication of blood transfusion. We present the case of a 46-year-old diabetic and hypertensive patient admitted to our hospital for recurrent episodes of urinary retention. Over initial 3 days of the admission, the patient received multiple units of packed red blood cells (RBC and fresh frozen plasma, uneventfully. However, the patient developed signs and symptoms suggestive of TACO with only small amount of the 4 th unit of RBC. The patient had to be shifted to the Intensive Care Unit for further management of this complication. Etiology of TACO is more complex than a mere circulatory overload and is still not completely understood. TACO leads to a prolonged hospital stay and morbidity in the patients developing this complication. TACO thus needs to be suspected in patients at risk for this complication.

    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

    to determine the best approach to detect autologous blood transfusions. Twenty-nine subjects were transfused with either one (n=8) or three (n=21) bags of autologous blood. Hemoglobin concentration ([Hb]), percentage of reticulocytes (%ret) and hemoglobin mass (Hbmass) were measured 1 day before reinfusion...... and six times after reinfusion. The sensitivity and specificity of a novel marker, Hbmr (based on Hbmass and %ret), was evaluated together with [Hb], Hbmass and OFF-hr by different passport methods. Our novel Hbmr marker showed superior sensitivity in detecting the highest dosage of transfused blood......, with OFF-hr showing equal or superior sensitivities at lower dosages. Hbmr and OFF-hr showed superior but equal sensitivities from 1 to 4 weeks after transfusion compared with [Hb] and Hbmass, with Hbmass being the only tenable prospect to detect acute transfusions. Because autologous blood transfusions...

    Backgrounds/Aims Although perioperative therapies have improved greatly, pancreatectomies still often need blood transfusions. However, the morbidity from blood transfusions, the poor prognosis of blood transfused patients, high cost, and decreasing supply of blood products is accelerating transfusion-free (TF) surgery in the patients who have pacreatectomies. The aim of this study was to assess the feasibility of TF pancreatectomies for patients who are Jehovah's Witness. Methods We investigated the possibility of TF pancreatectomies for the Jehovah's Witness patients undergoing pancreatectomies between January 2007 and Februay 2014. There were 4 cases of Whipple's operation, 4 of pylorus-preserving pancreaticoduodenectomy, 2 of radical antegrade modular pancreatosplenectomy and 1 of laparoscopic distal pancreatectomy. All were performed by one surgeon. Results Most of the TF pancreatecomies patients received perioperative blood augmentation and intraoperative acute normovolemic hemodilution (ANH). They received no blood transfusions at any time during their hospitalization, and pre- and intra-operative data and outcomes were acceptably favorable. Conclusions To the best of our knowledge, this report is the first successful consecutive pancreatectomy program for Jehovah's Witness not involving blood transfusion. TF pancreatectomy can be performed successfully in selected Jehovah's Witness. Postoperative prognosis and outcomes should be confirmed in follow up studies.

    2008-01-01

    The Mayo Clinic, in Rochester, Minnesota, recently set forth a directive to develop a Mayo Emergency Incident Command System (MEICS) plan to respond to major disasters. The MEICS plan that was developed interfaces with national response plans to ensure effective communication and coordination between our institution and local, state, and federal agencies to establish a common language and communication structure. The MEICS plan addresses multiple aspects of dealing with resource needs during a crisis, including the need for blood and transfusion medicine services. The MEICS plan was developed to supplement our current local emergency preparedness procedures and provide a mechanism for responding to the escalating severity of an emergency to deal with situations of a magnitude that is outside the normal experience. A plan was developed to interface the existing Transfusion Medicine disaster plan standard operating procedures (SOP) with the institutional and Department of Laboratory Medicine (DLMP) MEICS plans. The first step in developing this interface was defining MEICS. Other major steps were defining the chain of command, developing a method for visually indicating who is "in charge," planning communication, defining the actions to be taken, assessing resource needs, developing flowcharts and updating SOPs, and developing a blood rationing team to deal with anticipated blood shortages. Several key features of the interface and updated disaster plan that were developed are calling trees for response personnel, plans for relocating leadership to alternative command centers, and action sheets to assist with resource assessment. The action sheets also provide documentation of key actions by response personnel.

    Full Text Available Abstract Background Payments for red blood cell (RBC transfusions are separate from US Medicare bundled payments for dialysis-related services and medications. Our objective was to examine the economic burden for payers when chronic dialysis patients receive outpatient RBC transfusions. Methods Using Truven Health MarketScan® data (1/1/02-10/31/10 in this retrospective micro-costing economic analysis, we analyzed data from chronic dialysis patients who underwent at least 1 outpatient RBC transfusion who had at least 6 months of continuous enrollment prior to initial dialysis claim and at least 30 days post-transfusion follow-up. A conceptual model of transfusion-associated resource use based on current literature was employed to estimate outpatient RBC transfusion payments. Total payments per RBC transfusion episode included screening/monitoring (within 3 days, blood acquisition/administration (within 2 days, and associated complications (within 3 days for acute events; up to 45 days for chronic events. Results A total of 3283 patient transfusion episodes were included; 56.4% were men and 40.9% had Medicare supplemental insurance. Mean (standard deviation [SD] age was 60.9 (15.0 years, and mean Charlson comorbidity index was 4.3 (2.5. During a mean (SD follow-up of 495 (474 days, patients had a mean of 2.2 (3.8 outpatient RBC transfusion episodes. Mean/median (SD total payment per RBC transfusion episode was $854/$427 ($2,060 with 72.1% attributable to blood acquisition and administration payments. Complication payments ranged from mean (SD $213 ($168 for delayed hemolytic transfusion reaction to $19,466 ($15,424 for congestive heart failure. Conclusions Payments for outpatient RBC transfusion episodes were driven by blood acquisition and administration payments. While infrequent, transfusion complications increased payments substantially when they occurred.

    We report a patient with fulminant Lassa fever who responded dramatically to a 2.5-litre exchange transfusion of whole blood. On admission he was semicomatose with facial oedema and oral haemorrhage; his platelets showed markedly depressed aggregation to ADP; and his plasma inhibited the aggregation responses of normal platelets in vitro. Exchange transfusion resulted in rapid clinical improvement, recovery of platelet function, and disappearance of platelet-inhibitory activity in plasma. The patient died 2 weeks later from an acute encephalopathy. His initial response was sufficiently impressive to suggest that further evaluation of this therapeutic approach is justified in selected patients with overwhelming Lassa virus infection.

    This case of platelet transfusion in palliative care illustrates a common dilemma in transfusion medicine: approval of the use of a scarce, yet potentially life-saving, resource. As in this case, these decisions often involve seriously ill patients with acute needs and evolving goals of care. The use of resources to treat the patient at hand must be balanced against maintaining adequate resources to treat future patients. In this setting, the ethical principles of beneficence and social justice are in conflict. PMID:27550559

    2015-01-01

    Although red blood cells(RBCs) transfusion is sometimes associated with adverse reactions,anemia could also lead to increased morbidity and mortality in highrisk patients. For these reasons,the definition of perioperative strategies that aims to detect and treat preoperative anemia,prevent excessive blood loss,and define "optimal" transfusion algorithms is crucial. Although the treatment with preoperative iron and erythropoietin has been recommended in some specific conditions,several controversies exist regarding the benefit-to-risk balance associated with these treatments. Further studies are needed to better define the indications,dosage,and route of administration for preoperative iron with or without erythropoietin supplementation. Although restrictive transfusion strategies in patients undergoing cardiac surgery have been shown to effectively reduce the incidence and the amount of RBCs transfusion without increase in side effects,some high-risk patients(e.g.,symptomatic acute coronary syndrome) could benefit from higher hemoglobin concentrations. Despite all efforts made last decade,a significant amount of work remains to be done to improve hemoglobin optimization and transfusion strategies in patients undergoing cardiac surgery.

    Transfusion-transmitted infections remain among the most-feared complications of allogeneic blood transfusion. Thanks to several strategies including donor screening and deferral, blood testing and pathogen inactivation, their risks have reached all-time low levels, particularly in developed nations. Nonetheless, new and emerging infections remain a threat that is likely to exacerbate in the coming years with continued globalization and climate change. More effective strategies of pathogen inactivation and more vigilant horizon screening are hoped to abate the risk. Additionally, allogeneic transfusion has repeatedly been shown to be associated with worsening of outcomes in patients, including the documented increased risk of infections (often nosocomial) in recipients of transfusions. The underlying mechanism is likely to be related to immunosuppressive effects of allogeneic blood, iron content, and bacterial contamination. This issue is best addressed by more judicious and evidence-based use of allogeneic blood components to ensure the potential benefits outweigh the risks. PMID:26959944

    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.

    The ability of Bacillus cereus to cause foodborne toxicoinfections leads to increasing concerns regarding consumer protection. For the diarrhea-associated enterotoxins, the assessment of the non-hemolytic enterotoxin B (NheB) titer determined by a sandwich enzyme immunoassay (EIA) correlates best with in vitro cytotoxicity. In general, the regulation of enterotoxin expression of B. cereus is a coordinately-regulated process influenced by environmental, and probably also by host factors. As long as these factors are not completely understood, the currently-applied diagnostic procedures are based on indirect approaches to assess the potential virulence of an isolate. To date, sandwich EIA results serve as a surrogate marker to categorize isolates as either potentially low or highly toxic. Here, we report on a single amino acid exchange in the NheB sequence leading to an underestimation of the cytotoxic potential in a limited number of strains. During the screening of a large panel of B. cereus isolates, six showed uncommon features with low sandwich EIA titers despite high cytotoxicity. Sequence analysis revealed the point-mutation (Glu)151(Asp) in the potential binding region of the capture antibody. Application of this antibody also results in low titers in an indirect EIA format and shows variable detection intensities in Western-immunoblots. A commercially-available assay based on a lateral flow device detects all strains correctly as NheB producers in a qualitative manner. In conclusion, isolates showing low NheB titers should additionally be assayed in an indirect EIA or for their in vitro cytotoxicity to ensure a correct classification as either low or highly toxic.

    The report covers four cases presenting simultaneous indications for digitalisation and exchange transfusions. Intravenous administration of digoxin was followed: 1. by monitoring of the behaviour of the plasma digoxin level; 2. by determination of the total amount of glycoside eliminated by the blood exchange. Particular attention was paid to the effect of the delay between injection and exchange transfusion on the amount of digoxin eliminated. All four cases showed moderate falls in plasma levels. The amounts of digoxin eliminated by exchange transfusion were in reverse relationship to the delay between administration of digoxin and the blood exchange. At no time did the eliminated fraction exceed 5% of the total amount present in the body. PMID:837948

In the first 48 hours of ventilating patients with acute lung injury (ALI/acute respiratory distress syndrome (ARDS, a multipronged approach including packed red blood cell (PRBC transfusion is undertaken to maintain oxygen delivery. Hypothesis. We hypothesized children with ALI/ARDS transfused within 48 hours of initiating mechanical ventilation would have worse outcome. The course of 34 transfused patients was retrospectively compared to 45 nontransfused control patients admitted to the PICU at Helen DeVos Children’s Hospital between January 1st 2008 and December 31st 2009. Results. Mean hemoglobin (Hb prior to transfusion was 8.2 g/dl compared to 10.1 g/dl in control. P/F ratio decreased from 135.4±7.5 to 116.5±8.8 in transfused but increased from 148.0±8.0 to 190.4±17.8 (P<0.001 in control. OI increased in the transfused from 11.7±0.9 to 18.7±1.6 but not in control. Ventilator days in the transfused were 15.6±1.7 versus 9.5±0.6 days in control (P<0.001. There was a trend towards higher rates of MODS in transfused patients; 29.4% versus 17.7%, odds ratio 1.92, 95% CI; 0.6–5.6 Fisher exact P<0.282. Conclusion. This study suggests that early transfusions of patients with ALI/ARDS were associated with increased ventilatory needs.

    Full Text Available The beta-globin gene mutation in sickle cell anemia results in anemia and repeated bouts of vascular occlusion. The cumulative effect of these vasocclusive events is progressive damage to many organs including the kidneys, lungs, and brain. The transfusion of red blood cells (RBC can ameliorate many of these complications, but can be associated with both acute and chronic complications, including iron overload. The objective of the Best Practices in Transfusion Medicine for Patients with Sickle Cell Disease (SCD Conference was to review the available published evidence and clinical experience surrounding the use of RBC transfusions for sickle cell disease by a panel of experts. The expert panel developed explicit clinical guidelines for the use of RBC in SCD patients. The panel also made recommendations for further research.  A set of guidelines were produced for dissemination to pertinent stakeholders. If implemented, these clinical pathways have the potential to optimize the use of red blood cell transfusions in SCD.

    2010-12-01

    Full Text Available Abstract Background Primary postpartum haemorrhage is an obstetrical emergency often causing acute anaemia that may require immediate red blood cell (RBC transfusion. This anaemia results in symptoms such as fatigue, which may have major impact on the health-related quality of life. RBC transfusion is generally thought to alleviate these undesirable effects although it may cause transfusion reactions. Moreover, the postpartum haemoglobin level seems to influence fatigue only for a short period of time. At present, there are no strict transfusion criteria for this specific indication, resulting in a wide variation in postpartum policy of RBC transfusion in the Netherlands. Methods/Design The WOMB trial is a multicentre randomised non-inferiority trial. Women with acute anaemia due to postpartum haemorrhage, 12-24 hours after delivery and not initially treated with RBC transfusion, are eligible for randomisation. Patients with severe physical complaints are excluded. Patients are randomised for either RBC transfusion or expectant management. Health related quality of life (HRQoL will be assessed at inclusion, at three days and one, three and six weeks postpartum with three validated measures (Multi-dimensional Fatigue Inventory, ShortForm-36, EuroQol-5D.

Our aim was to determine if transfusions with IPF-rich solutions, during autologous peripheral blood stem cell transplantation, reduce the occurrence of bleeding and hemorrhagic complications.Patients and methods: Transfusions were administered to 40 children, affected with hematological pathologies, who underwent autologous peripheral hematopoietic progenitor cell transplantation. There were two groups of 20 patients, one group treated with IPF-poor and the other with IPF-rich solutions. In the two groups, the conditioning regimen was the same for the same pathology (hematological pathologies: 14 acute lymphoblastic leukemia; twelve acute myelocytic leukemia; four non-Hodgkin's lymphoma; two Hodgkin's lymphoma; eight solid tumors. A new automated analyzer was used to quantify the IPF: the XE2100 (Sysmex, Kobe, Japan blood cell counter with upgraded software.Results: The 20 patients who received solutions with a high percentage of IPF (3%–9% of total number of infused platelets required fewer transfusions than the 20 patients who received transfusions with a low percentage of IPF (0%–1% of total number of infused platelets: 83 versus 129 (mean of number of transfusions 4.15 versus 6.45 and a significant difference was found between the two groups by using the Mann–Whitney test (P < 0.001. The prophylactic transfusions decreased from three to two per week.

    The transmission of parasitic organisms through transfusion is relatively rare. Of the major transfusion-transmitted diseases, malaria is a major cause of TTIP in tropical countries whereas babesiosis and Chagas' disease pose the greatest threat to donors in the USA In both cases, this is due to the increased number of potentially infected donors. There are no reliable serologic tests available to screen donors for any of these organisms and the focus for prevention remains on adherence to donor screening guidelines that address travel history and previous infection with the etiologic agent. One goal is the development of tests that are able to screen for and identify donors potentially infectious for parasitic infections without causing the deferral of a large number of non-infectious donors or significantly increasing costs. Ideally, methods to inactivate the infectious organism will provide an element of added safety to the blood supply. PMID:20859503

    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

    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

    Full Text Available Studies in relation to blood conservation and responses to transfusion are scarce for ruminants. We evaluated the clinical manifestations of sheep that received a single homologous transfusion of whole blood, focusing on transfusion reactions. Eighteen adult sheep were subjected to a single phlebotomy to withdraw 40% of the total blood volume, which was placed into CPDA-1 bags and then divided into G0, animals that received fresh blood, and G15 and G35, animals that received blood stored for 15 or 35 days, respectively. Clinical observations were recorded throughout the transfusion, whereas heart rate, respiratory rate, and rectal temperature were assessed at the following times: 24 hours after phlebotomy and before transfusion; 30 minutes, six, twelve, 24, 48, 72, and 96 hours and eight and 16 days after transfusion. All groups presented transfusion reactions, among which hyperthermia was the most frequent (50% of animals. Tachycardia occurred most frequently in the G35 animals (50% of them. During transfusion G35 animals presented more clinical manifestation (P<0.05. Transfusion of fresh or stored total blood improved the blood volume, but transfusion reactions occurred, demonstrating that a single transfusion of fresh or stored blood can cause inflammatory and febrile nonhemolytic transfusion reactions in sheep.

    2016-07-01

    Because testing of donors for Babesia microti has become available, it is important to determine the kinds of patients who should receive B microti-tested blood. We searched PubMed, AABB abstracts, and FDA Web site to identify all cases of transfusion-transmitted babesiosis (TTB). Cases were analyzed for underlying medical condition, age, presence of spleen, and reason for transfusion in relation to 5 classes of recipient outcome severity. Sixty-seven reports included 256 transfusion cases where donor tested positive for B microti, 165 of which resulted in TTB. Sixty recipients did not develop disease or become test positive, and test results were not known for 31 more. The 165 cases of TTB involved hematologic (19%), neonate (10%), cardiovascular (8%), and gastrointestinal (6%) patients. Thirty-two (19%) of the 165 infected patients died with death attributed to babesiosis in 25 of the cases. Nine (5%) were asymptomatic, 27 (16%) were symptomatic but had uncomplicated disease, and 16 (10%) had complicated disease. The severity of disease was mixed among many disease categories. Patients >65 years of age included the largest number of recipients (59/165, 36%) and deaths (11/32, 34%), although deaths occurred in other age groups as well. TTB cases were predominantly due to red cells (133 of 140 specified units), with red blood cell units processed in a variety of ways and at all storage duration. TTB with complicated babesiosis and/or death occurred in patients of all age groups and with a variety of underlying medical conditions. PMID:27260107

    Full Text Available Abstract Background Patients suffering from intracerebral haemorrhage have a poor prognosis, especially if they are using antiplatelet therapy. Currently, no effective acute treatment option for intracerebral haemorrhage exists. Limiting the early growth of intracerebral haemorrhage volume which continues the first hours after admission seems a promising strategy. Because intracerebral haemorrhage patients who are on antiplatelet therapy have been shown to be particularly at risk of early haematoma growth, platelet transfusion may have a beneficial effect. Methods/Design The primary objective is to investigate whether platelet transfusion improves outcome in intracerebral haemorrhage patients who are on antiplatelet treatment. The PATCH study is a prospective, randomised, multi-centre study with open treatment and blind endpoint evaluation. Patients will be randomised to receive platelet transfusion within six hours or standard care. The primary endpoint is functional health after three months. The main secondary endpoints are safety of platelet transfusion and the occurrence of haematoma growth. To detect an absolute poor outcome reduction of 20%, a total of 190 patients will be included. Discussion To our knowledge this is the first randomised controlled trial of platelet transfusion for an acute haemorrhagic disease.

    Normal pregnancies depend on successful implantation of the placenta in the uterus. The trophoblast which forms the ultimate interface between the fetal and maternal tissue seems to lack the foreign (allo) antigens (namely HLA/TLX) required to induce immunological rejection reactions in the mother. It was previously believed that the trophoblast expressed paternal allo antigens and that successful pregnancies were dependent on so called 'kind' (non-cytotoxic or non-complement binding) blocking antibodies in order to protect the fetal unit from maternal cytotoxic T-cells and -antibodies. Blocking antibodies attached to paternal antigens on the trophoblast were assumed to prevent maternal cytotoxic T cell and cytotoxic antibodies from recognising the trophoblast as foreign tissue. On this assumption it was reasoned that transfusions of paternal HLA-expressing lymphocytes would increase maternal antipaternal HLA (TLX) blocking antibodies and thus be beneficial to women who experienced multiple miscarriages. There is, however, no scientific evidence for a specific immune response after lymphocyte transfusions that fulfil this function. Immunological tests, as for example mixed lymphocyte culture (MLC), on peripheral blood lymphocytes do not seem to reflect the local immune state in the uterus, either in the pregnant or the non-pregnant state. Since the trophoblast forms the ultimate interface between fetal and maternal tissue, its structure, secretions, and interaction with the decidua must be of definite importance for implantation of the blastocyst and growth of the embryo.

    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.

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

    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

When viewed using a prismatic lens of history, recurrent themes regarding adverse HT sequelae separate and become apparent. These can be broadly classified into three categories: infectious, noninfectious, and administrative/logistical.

    Stout, Lynn

    Within Scottish hospitals transfusion education is mandatory for all staff involved in the process of transfusion. Currently two modes of delivery exist, face-to-face and e-learning. The researcher,a transfusion practitioner, wished to evaluate the perceptions of registered nurses within her local children's hospital to the transfusion education available. The aim of the evaluation was to ascertain whether there were perceived benefits, whether expectations were met and whether nurses perceived that there were any barriers to undertaking the education. Both quantitative and qualitative data were obtained by means of a questionnaire; all registered nurses in the hospital were invited to participate. The study indicates a high level of compliance with mandatory transfusion education and suggests both satisfaction and perceived benefits with transfusion education among those who responded. Some barriers were highlighted, but it was noted that these were not exclusive to transfusion education and in the current challenging environment with conflicting priorities on time, resolution may be complex.

    Jr(a) is a high-prevalence antigen. The rare Jr(a-) individuals can form anti-Jr(a) after exposure to the Jr(a) antigen through transfusion or pregnancy. The clinical significance of anti-Jr(a) is not well established. This study reports a case of a 31-year-old woman with a previously identified anti-Jr(a) who required massive transfusion of RBCs after developing life-threatening postpartum disseminated intravascular coagulopathy. Despite the emergent transfusion of 15 units of Jr(a) untested RBCs, she did not develop laboratory or clinical evidence of acute hemolysis. The patient's anti-Jr(a) had a pretransfusion titer of 4 and a monocyte monolayer assay (MMA) reactivity of 68.5% (reactivity > 5% is considered capable of shortening the survival of incompatible RBCs). The titer increased fourfold to 64 and the MMA reactivity was 72.5% on Day 10 posttransfusion. Review of laboratory data showed evidence of a mild delayed hemolytic transfusion reaction by Day 10 posttransfusion. Despite rare reports of hemolytic transfusion reactions due to anti-Jr(a) in the literature, most cases, including this one, report that this antibody is clinically insignificant or causes only mild delayed hemolysis. Clinicians should be advised to balance the risks of withholding transfusion with the small chance of significant hemolysis after transfusion of Jr(a+) RBCs in the presence of anti-Jr(a).

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

    While platelets are primary mediators of hemostasis, there is emerging evidence to show that they may also mediate pathologic thrombogenesis. Little data are available on risks and benefits associated with platelet transfusions in thrombotic thrombocytopenic purpura (TTP), heparin-induced thrombocytopenia (HIT) and immune thrombocytopenic purpura (ITP). This study utilized the Nationwide Inpatient Sample to evaluate the current in-hospital platelet transfusion practices and their association with arterial/venous thrombosis, acute myocardial infarction (AMI), stroke, and in-hospital mortality over 5 years (2007-2011). Age and gender-adjusted odds ratios (adjOR) associated with platelet transfusions were calculated. There were 10 624 hospitalizations with TTP; 6332 with HIT and 79 980 with ITP. Platelet transfusions were reported in 10.1% TTP, 7.1% HIT, and 25.8% ITP admissions. Platelet transfusions in TTP were associated with higher odds of arterial thrombosis (adjOR = 5.8, 95%CI = 1.3-26.6), AMI (adjOR = 2.0, 95%CI = 1.2-3.3) and mortality (adjOR = 2.0,95%CI = 1.3-3.0), but not venous thrombosis. Platelet transfusions in HIT were associated with higher odds of arterial thrombosis (adjOR = 3.4, 95%CI = 1.2-9.5) and mortality (adjOR = 5.2, 95%CI = 2.6-10.5) but not venous thrombosis. Except for AMI, all relationships remained significant after adjusting for clinical severity and acuity. No associations were significant for ITP. Platelet transfusions are associated with higher odds of arterial thrombosis and mortality among TTP and HIT 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

    Clinical blood transfusion is one of the most important supportive therapy for patients with tumor. The blood transfusion has dual effects for patients with tumor. First, blood transfusion can rectify anemia and improve oxygen saturation, accelerate oxidation and necrosis for tumor cells; the second, blood transfusion can induce immunosuppression, tumor recurrence and postoperative infection for tumor patients. Filtering white blood cells (WBC) before blood transfusion can decrease the incidence of the adverse reactions. The rational perioperative autotransfusion for patients with tumors is focus to which the world medical sciences pay close attention. In this article, the support effect of blood transfusion for treatment of tumor patients, blood transfusion and immunosuppression, blood transfusion and postoperative infection and relapse of tumor patients, depleted leukocyte blood transfusion and autologous transfusion of tumor patients are reviewed.

  19. Transfusion of blood and blood component therapy for postpartum haemorrhage at a tertiary referral center

    International Nuclear Information System (INIS)

    Objective: To determine the practice of transfusion of blood and blood products in cases of postpartum haemorrhage, at a tertiary referral center. Methods: A retrospective study was conducted where medical records were reviewed for women, who either delivered or were admitted in labour suite with diagnosis of postpartum haemorrhage. The study period extended from Jan 2008 to Oct 2009. During a period of 22 months, records were reviewed for transfusion of blood and blood products in above group of women. Data were analyzed for descriptive statistics. Results: During the study period, a total of 4744 patients were admitted in the labour suite. A total of 113 (2.36%) women were diagnosed with Post partum haemorrhage. Uterine atony was the commonest cause of PPH, followed by genital tract trauma. A total of 81(71%) women received transfusion of blood and blood components (1.6%). The mean blood loss was 1088 ml (+- 584ml). Transfusion of blood and blood component therapy was significantly more in women who underwent caesarean section, compared to those women who delivered vaginally. There was one case of acute tubular necrosis due to PPH, and seven maternal deaths. The mean hospital stay was of +- 3 days. Conclusion: In this hospital based study, the prevalence of PPH was 2.36 +- %, and the rate of transfusion of blood and blood products was 1.6%.

    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.

    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.

    In France since 2002, the single-donor transfusion protocol, using four pediatric units from the same adult donor's packed red blood cells (PRBCs) in multiply transfused newborns, is recommended in preterm neonates to reduce the risks of infection and alloimmunization. This protocol is controversial, however, because it causes the transfusion of stored blood, which could have adverse consequences. Before the new recommendations of the French Haute Autorité de santé (National authority for health) in 2015, we conducted a national practice survey in 63 neonatal intensive care units (NICU) and a retrospective study of the characteristics of 103 children transfused within our unit, to better target beneficiaries. The practice survey showed that 30 % of French NICUs no longer used the protocol in 2014, due to logistical or financial problems, or concerns about the transfusion of stored blood. The practices were heterogeneous. Few NICUs used a written protocol. In our NICU, the use of single-donor protocol involved the use of units stored for more than 20 days in half of the cases beginning with the third unit used. Six-term newborns were mainly transfused once, which does not seem to warrant the single-donor transfusion protocol. The use of this protocol caused the loss of 50 % of the manufactured units, which go unused. In multivariate analysis, two factors were predictive of multiple transfusion within our population of 95 premature neonates undergoing transfusion: low-term and a high Clinical Risk Index for Babies (CRIB) score. The risk of multiple transfusions would be reduced by about 15 % for each additional week of gestation and approximately 16 % per point within the CRIB score. These variables integrated into a statistical model predict the risk of multiplying transfusions. According to the ROC curve, a calculated risk higher than 50 % is the appropriate cut-off value to transfuse with the single-donor transfusion protocol. This would limit its

    This study provides data on National Blood Service (NBS) red blood cell (RBC, n = 9142), platelet (PLT, n = 4232) and fresh frozen plasma (FFP, n = 3584) recipients independently sampled by monthly quota from 29 representative hospitals over 12 months in 2001-2002. Hospitals were stratified by size according to total yearly RBC issues. Transfusion indications were chosen from diagnostic and procedural codes, and recipients grouped into Epidemiology and Survival of Transfusion Recipients Case-mix Groups (E-CMGs). The main E-CMGs were digestive [19% of RBC recipients; including 5% gastrointestinal (GI) bleeds and 3% colorectal surgery], musculoskeletal (15%; 12% hip and knee replacement), haematology (13%) and obstetrics and gynaecology (10%). Renal failure, fractured neck of femur, cardiac artery by-pass grafting (CABG) and paediatrics, each accounted for 3-4% recipients. FFP recipients: the main E-CMGs were digestive (21% of FFP recipients; including 7% GI bleeds and 3% colorectal surgery), hepatobiliary (15%; 7% liver disease and 2% liver transplant), cardiac (12%) and paediatrics (9%) The renal, paediatrics, vascular and haematology E-CMGs each had 6-7% of recipients. PLT recipients: the main E-CMGs were haematology (27% of PLT recipients; including 9% lymphoma and 8% acute leukaemia), cardiac (17%), paediatrics (13%), hepatobiliary (10%) and digestive (9%). Back-weighting gave national estimates of 433 000 RBC, 57 500 FFP and 41 500 PLT recipients/year in England and North Wales, median age 69, 64 and 59 years, respectively. Digestive and hepatobiliary indications emerged as the top reason for transfusion in RBC and FFP recipients, and was also a frequent indication in PLT recipients.

    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).

    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

    The representation of blood transfusion and donation of blood in the comic strip has never been studied. The comic strip, which is a relatively recent art, emerged in the 19th century before becoming a mass medium during the 20th century. We have sought, by calling on collectors and using the resources of Internet, comic strips devoted, wholly or in part, to the themes of transfusion and blood donation. We present some of them here in chronologic order, indicating the title, country of origin, year of publication, and names of authors. The theme of the superhero using transfusion to transmit his virtues or his powers is repeated throughout the 20th century in North American comic strips. More recently, comic strips have been conceived from the outset with a promotional aim. They perpetuate positive images and are directed toward a young readership, wielding humor to reduce the fear of venipuncture. Few comic strips denounce the abuse of the commercialization of products derived from the human body. The image of transfusion and blood donation given by the comic strips is not to be underestimated because their readership is primarily children, some of whom will become blood donors. Furthermore, if some readers are transfused during their lives, the impact of a memory more or less conscious of these childhood readings may resurface, both in hopes and in fears.

  14. Diagnosis of Beta-thalassaemia major in previously transfused patients

    International Nuclear Information System (INIS)

    Objective: The study was conducted to evaluate the effects of blood transfusion(s) on the haematological picture of beta-thalassaemia major. Results: Out of the 280 patients 109 (39%) had received one or more blood transfusions (cases). The remaining 171 patients who did not receive any transfusion served as controls. The mean MCV, MCH and Hb-F in cases were significantly higher than in the controls (p4 transfusions (17%) (p=0.016). In the occasionally transfused patients Hb-F level was directly related to the time since last transfusion. In 44/109 (40%) transfused patients (Hb-F>30%) the diagnosis of thalassaemia was not difficult. In 54/109 (50%) patients (Hb-:5-30%) the diagnosis was aided by parent's study, while PCR for thalassaemia mutation was required in 11/109 (10%) patients (Hb-F <5%). Conclusion: In most transfused patients of thalassaemia major MCV and MCH were significantly higher while Hb-F was lower than in the un-transfused patients. There was a linear correlation between Hb-F level and time since last transfusion in the occasionally transfused patients. However, the reduction in Hb-F level was more marked and sustained in multipally transfused patients. Parent's study and PCR are useful aids in establishing the correct diagnosis in these patients.

    Full Text Available To determine the role of blood transfusion protocols on retinopathy of prematurity (ROP, a prospective cohort study on 57 premature infants under 1501 grams birth weight was performed. Fourteen day-old infants were divided into two groups randomly. Infants in group 1 (n=27 received packed red blood cell transfusion only if specific medical signs were met and their hematocrit level was under 30%. Infants in group 2 (n=30 received blood transfusion to maintain their hematocrit level > 40% regardless of their signs. All infants had an eye examination by indirect ophthalmoscopy from 28 to 40 days of life for detecting ROP. We did not find any significant difference in ROP incidence between both groups.

    Full Text Available Cancer patients are commonly transfused with blood products immediately before, during or after major surgery. Blood loss and haemodilution are the most common causes of red blood cells (RBCs administration and coagulopathies are the indications for the infusion of fresh-frozen plasma (FFP, cryoprecipitates and platelets. Transfusion-related immune modulation is a complication associated with the administration of blood products. A decreased immune surveillance as a consequence of blood transfusions has been linked to cancer recurrence and progression. Moreover, soluble factors present in packed RBCs, platelets and FFP can directly stimulate tumour growth and spread. Two meta-analyses suggest that the administration of blood products is associated with shorter recurrence-free survival and overall survival after colorectal cancer surgery. More studies are needed to show such association in different cancer patient populations.

    Full Text Available Platelet transfusions have contributed to the revolutionary modern treatment of hypoproliferative thrombocytopenia. Despite the long-term application of platelet transfusion in therapeutics, all aspects of their optimal use (i.e., in cases of ABO and/or Rh (D incompatibility have not been definitively determined yet. We reviewed the available data on transfusion practices and outcome in ABO and RhD incompatibility and platelet refractoriness due to anti-human leukocyte antigen (HLA antibodies. Transfusion of platelets with major ABO-incompatibility is related to reduced posttransfusion platelet (PLT count increments, compared to ABO-identical and minor, but still are equally effective in preventing clinical bleeding. ABO-minor incompatible transfusions pose the risk of an acute hemolytic reaction of the recipient that is not always related to high anti-A, B donor titers. ABO-identical PLT transfusion seems to be the most effective and safest therapeutic strategy. Exclusive ABO-identical platelet transfusion policy could be feasible, but alternative approaches could facilitate platelet inventory management. Transfusion of platelets from RhD positive donors to RhD negative patients is considered to be effective and safe though is associated with low rate of anti-D alloimmunization due to contaminating red blood cells. The prevention of D alloimmunization is recommended only for women of childbearing age. HLA alloimmunization is a major cause of platelet refractoriness. Managing patients with refractoriness with cross-matched or HLA-matched platelets is the current practice although data are still lacking for the efficacy of this practice in terms of clinical outcome. Leukoreduction contributes to the reduction of both HLA and anti-D alloimmunization.

    Transfusion medicine has become a large and complex specialty. Although there are now systematic reviews covering many aspects of transfusion, these span a large number of clinical areas and are published across more than a hundred different medical journals, making it difficult for transfusion medicine practitioners and researchers to keep abreast of the current high-level evidence. In response to this problem, NHS Blood and Transplant's Systematic Review Initiative (SRI) has produced a comprehensive overview of systematic reviews in transfusion medicine. A systematic search (to December 2009) and screening procedure were followed by the appraisal of systematic reviews according to predefined inclusion criteria. The 340 eligible systematic reviews were mapped to 10 transfusion intervention groups and 14 topic groups within clinical medicine. Trends in the systematic review literature were examined and gaps in the literature described. The spread of systematic reviews across clinical areas was found to be very uneven, with some areas underreviewed and others with multiple systematic reviews on the same topic, making the identification of the best evidence for current transfusion practice a continuing challenge. References and links to all systematic reviews included in this overview can be freely accessed via the SRI's new online database, the Transfusion Evidence Library (www.transfusionguidelines.org).

    Evidence suggests that perioperative allogeneic blood transfusion increases the risk of infectious complications after major surgery and of cancer recurrence after curative operation. This has been attributed to immunosuppression. Several authors have suggested that filtered whole blood and/or red...... cell concentrate, or leucocyte- and buffy coat-reduced red cells in artificial medium or their own plasma, may reduce postoperative immunosuppression. It was also anticipated that the use of autologous blood might minimize the risk of perioperative transfusion, but studies have unexpectedly shown...

    Platelets perform a vital role in hemostasis and their role in inflammation is becoming increasingly evident. Blood transfusion is the most common procedure performed in hospitals and platelet transfusions comprise a significant proportion. Over the past few decades, retrospective studies and randomized clinical trials have demonstrated that blood transfusion is more harmful than previously thought and is associated with numerous complications, such as transfusion-associated lung injury, transfusion-associated cardiac overload, transfusion-associated immune modulation, and infectious diseases such as human immunodeficiency virus, hepatitis C virus, and hepatitis B virus. Recent data suggest an association between platelet transfusion and thrombosis. This review will highlight the mechanistic issues that may be relevant to the epidemiologic associations of platelet transfusion with thrombosis and mortality in critically ill patients.

    Objective To explore the efficay of low-dose decitabine combined with fractional allogeneic hematopoietic stem cell transfusion( micro transplantation) for treatment of elderly patients with acute myeloid leukemia transformed from myelodysplastic syndrome ( MDS-AML) .Methods Two patients diagnosed as MDS-AML were treated with chemotherapy regimen of low-dose decitabine or decitabine combined with CAG(cytosine arabinoside+aclacinomycin) and micro transplantation.The donors were children of patients with human leukocyte antigen semi-matched.Peripheral blood stem cells from the donors were mobilized with granulocyte colony-stimulating factor and then collected. Patients transfused PBSC about 36 hours after the chemotherapy finished.The disease status,platelet levels,survival timeand side effects were observed.Re sults Two cases did not achieve complete response.The survival times of Case 1 and Case 2 were 2 months and 4 months respectively. The platelet level in Case 1 increased remarkably after treatment,and reached to the maximal level of 59 ×109/L.No platelet transfusion was observed in Case 1.In Case 2,the interval of platelet transfusion was prolonged,and the patient was gradually independent on platelet transfusions. No graft-versus-host disease occurred in the two patients.Conclusion For elderly patients with MDS-AML,low-dose decitabine combined with micro transplantation can not cure the disease,but can prolong the survival time,increase the level of platelet and improve the quality of life.%目的 观察小剂量地西他滨联合异基因造血干细胞分次输注(微移植)治疗老年骨髓增生异常综合征转急性髓性白血病( MDS-AML)的疗效. 方法 对2例确诊为MDS-AML患者分别予小剂量地西他滨或地西他滨联合CAG方案(阿糖胞苷+阿克拉霉素)化疗加微移植治疗,供者为人类白细胞抗原半相合的患者子女,采集重组人粒细胞集落刺激因子动员后的供者外周血

    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 Yen-Michael S Hsu,1 Thorsten Haas,2 Melissa M Cushing1 1Department of Pathology and Laboratory Medicine, Weill Cornell Medical College, New York, NY, USA; 2Department of Anesthesia, University Children's Hospital Zurich, Zurich, Switzerland Abstract: Massive transfusion protocols (MTPs are established to provide rapid blood replacement in a setting of severe hemorrhage. Early optimal blood transfusion is essential to sustain organ perfusion and oxygenation. There are many variables to consider when establishing an MTP, and studies have prospectively evaluated different scenarios and patient populations to establish the best practices to attain improved patient outcomes. The establishment and utilization of an optimal MTP is challenging given the ever-changing patient status during resuscitation efforts. Much of the MTP literature comes from the trauma population, due to the fact that massive hemorrhage is the leading cause of preventable trauma-related death. As we come to further understand the positive and negative clinical impacts of transfusion-related factors, massive transfusion practice can be further refined. This article will first discuss specific MTPs targeting different patient populations and current relevant international guidelines. Then, we will examine a wide selection of therapeutic products to support MTPs, including newly available products and the most suitable of the traditional products. Lastly, we will discuss the best design for an MTP, including ratio-based MTPs and MTPs based on the use of point-of-care coagulation diagnostic tools.

    Djoudi, R

    2013-05-01

    The use of therapeutic plasma has increased in France by more than 40% since 2002. This growth may be explained by the improvement in transfusion safety, the diminution of the risk of transmission of pathogens and the regained confidence of the physicians in blood products. Therapeutic plasma also benefits from additional procedures to reduce infectious (securisation) or immunological risks (selection of blood donors). Its application in massive transfusions has undergone a significant evolution over the last few years. A proactive attitude favouring early and important use of plasma on the basis of pre-established protocols is advocated henceforth. The prescription of therapeutic plasma for other indications must be guided by the results of biological tests and an evaluation of the haemorrhagic risk. Despite regular updating of the guidelines for good transfusion practice, plasma is still sometimes prescribed for prophylactic purposes in situations where the biological and/or clinical criteria do not justify it. Moreover, it is not recommended to use fresh frozen plasma in cases of deficiency of coagulation factors if the specific concentrates are available as intravenous fluids. Complementary clinical studies will be necessary to evaluate, in certain indications, the real benefits of the transfusion of plasma and the interest of replacing it by concentrates of coagulant factors (fibrinogen, prothrombin complex).

    Full Text Available This prospective longitudinal study investigated the progression of haematological changes in 32 transfused and 54 non-transfused dogs naturally infected with Babesia rossi over the 1st 6 days following diagnosis and treatment. The effect of patient age on the results of complete blood counts was determined. Haematology data were analysed at presentation and at 24 hours, 3 days and 6 days after presentation. Dogs were treated with diminazene aceturate at diagnosis and a blood transfusion was given if deemed clinically required. Mildly to moderately regenerative normocytic normochromic anaemia was observed in all dogs throughout the study period. Transfused dogs more often had an inflammatory leukogram at presentation and at 24 hours, than dogs that were not transfused. In dogs with a left shift, a concurrent normal or decreased segmented neutrophil count was found more commonly than neutrophilia. Severe thrombocytopenia that resolved within a week was common. Blood transfusion alleviated the anaemia, but had no significant effect on white blood cell or platelet responses. Blood cell responses were not significantly influenced by age. In conclusion, the red blood cell and white blood cell responses were less than expected in dogs with babesiosis, given the degree of anaemia and inflammation present. The magnitude of thrombocytopenia and rapid return of the platelet count to normal suggested a possible immune-mediated mechanism for the thrombocytopenia.

    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.

    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.

    2005-01-01

    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.

  1. Blood transfusion: patient identification and empowerment.

    Stout, Lynn; Joseph, Sundari

    Positive patient identification is pivotal to several steps of the transfusion process; it is integral to ensuring that the correct blood is given to the correct patient. If patient misidentification occurs, this has potentially fatal consequences for patients. Historically patient involvement in healthcare has focused on clinical decision making, where the patient, having been provided with medical information, is encouraged to become involved in the decisions related to their individualised treatment. This article explores the aspects of patient contribution to patient safety relating to positive patient identification in transfusion. When involving patients in their care, however, clinicians must recognise the diversity of patients and the capacity of the patient to be involved. It must not be assumed that all patients will be willing or indeed able to participate. Additionally, clinicians' attitudes to patient involvement in patient safety can determine whether cultural change is successful.

    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

    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 In general, the risk of transfusion-transmitted infections has been greatly reduced today. However, blood-borne bacterial and parasitic infections and emerging infections transmitted through transfusion are an area of increasing concern. Implementation of stringent donor eligibility criteria, improved donor screening and more sophisticated as well as sensitive methods of antibody, antigen and viral genome detection, have virtually eliminated transfusion transmitted infection in developed countries. In developing countries like India, the risk of transfusion-transmitted infections is still considerable. A comprehensive MEDLINE search and review of relevant transfusion medicine literature were carried out and the data extracted and studied with particular reference to emerging pathogens transmitted through blood transfusion and posing a huge threat.

We hypothesized that a higher transfusion threshold would improve ambulation after hip revision...... received RBC. CONCLUSIONS: A Hb transfusion threshold of 8.9 g/dL was associated with a statistically significantly faster TUG after hip revision surgery compared to a threshold of 7.3 g/dL but the clinical importance is questionable and the groups did not differ in Hb at the time of testing....

    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 Aims: In the present study acute leukemic children were studied to determine the incidence and principal site of infection, correlation with absolute neutrophil count, causative organisms and to standardize the initial empirical anti microbial therapy. Materials and methods: A total 40 children in the age group 6 month to 12 year with acute leukemia relapse were included in this study. A total 82 infectious episodes including 61 febrile episodes were investigated for infectious etiology. Results: We found that the frequency of infections increased significantly with the degree of immunocompromisation specially neutropenia (ANC < 500/cmm. The skin and soft tissue was the commonest site of infection (26.83%, followed by respiratory tract (21.95%. Staphylococcus nonhemolytic coagulase-negative (34%, followed by Klebsiella (17% were the most common organisms isolated from blood. Staphylococcus non-hemolytic coagulase-negative was also the commonest isolate (26% from other sites of infection. Most strains were sensitive to Cloxacillin, cephalosporin and aminoglycosides. Conclusion: For the treatment of febrile episodes, empirical use of beta-lactamase resistant penicillin e.g. Cloxacillin or cephalosporin combined with an aminoglycosides with a broad spectrum antifungal like fluconazole in selective cases at the first sign of infection is recommended.

    Lung function abnormalities occur in children with sickle cell disease (SCD) and may be associated with elevated pulmonary blood volume. To investigate that association, we determined whether blood transfusion in SCD children acutely increased pulmonary capillary blood volume (PCBV) and increased respiratory system resistance (Rrs5). Measurements of Rrs5 and spirometry were made before and after blood transfusion in 18 children, median age 14.2 (6.6-18.5) years. Diffusing capacity for carbon monoxide and nitric oxide were assessed to calculate the PCBV. Post transfusion, the median Rrs5 had increased from 127.4 to 141.3% predicted (pvolume from 39.7 to 64.1 ml/m2 (pvolume in one second (p=0.0056) and vital capacity (p=0.0008) decreased. The increase in Rrs5 correlated with the increase in PCBV (r=0.50, p=0.0493). Increased pulmonary capillary blood volume may at least partially explain the lung function abnormalities in SCD children.

    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

    Full Text Available The Transfusion Medicine Service (TMS covers diverse clinical and laboratory-based services that must be delivered with accuracy, efficiency and reliability. TMS oversight is shared by multiple regulatory agencies that cover product manufacturing and validation standards geared toward patient safety. These demands present significant informatics challenges. Over the past few decades, TMS information systems have improved to better handle blood product manufacturing, inventory, delivery, tracking and documentation. Audit trails and access to electronic databases have greatly facilitated product traceability and biovigilance efforts. Modern blood bank computing has enabled novel applications such as the electronic crossmatch, kiosk-based blood product delivery systems, and self-administered computerized blood donor interview and eligibility determination. With increasing use of barcoding technology, there has been a marked improvement in patient and specimen identification. Moreover, the emergence of national and international labeling standards such as ISBT 128 have facilitated the availability, movement and tracking of blood products across national and international boundaries. TMS has only recently begun to leverage the electronic medical record to address quality issues in transfusion practice and promote standardized documentation within institutions. With improved technology, future growth is expected in blood bank automation and product labeling with applications such as radio frequency identification devices. This article reviews several of these key informatics issues relevant to the contemporary practice of TMS.

    Hepatitis E virus (HEV) is a non-enveloped RNA virus transmitted by the fecal-oral route. Autochthonous hepatitis E occurring in developed countries is caused by genotypes 3 and 4 and is a zoonotic infection. Humans are infected mostly after ingestion of undercooked meat from infected animals. Most HEV 3 and 4 infections are clinically inapparent. However, genotype 3 (HEV 3) can lead to chronic hepatitis in immuno-compromised patients such as organ-transplant recipients and patients with haematological malignancies. In Europe, HEV 3 is implicated in transfusion-transmitted HEV infection. In France, as observed in several European countries, prevalence of HEV RNA and specific IgG antibodies are high indicating that viral circulation is important. The systematic HEV NAT screening of blood donations used for preparation of solvent detergent plasma indicate that 1 to 2218 donation is infected by HEV RNA. The need or implementation's impacts of safety measures to prevent HEV transmission by blood transfusion are under reflexion by French's health authorities. The HEV NAT screening is the only available tool of prevention. Alternative strategies are under investigation including individual or mini pool NAT testing all or part of blood donations.

    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

    In this review the different mechanisms of aging and frailty such as DNA defects due to impaired DNA repair, inflammatory processes, disturbances of oxidative phosphorylation are discussed together with mechanisms of cell repair. Components of blood plasma, such as the growth-differentiation protein GDF11, were shown to enhance neurogenesis and to improve the vasculature in the animal cortex and to rejuvenate muscle tissue. Advances in laboratory assays allow to identify plasma proteins that may affect tissue regeneration. This new knowledge from animal research might affect transfusion practice in geriatric patients in the future. Provided it can be translated and confirmed in human research, blood products might no longer be considered only as oxygen carriers or drugs to improve hemostasis. In the present time blood transfusion (RBCs, plasma or platelets) should be directed by differentiated guidelines considering not only cut-off values of hemoglobin, platelet count or coagulation but also old age-specific biologic variation, comorbidities and the clinical context e.g. of bleeding.

    In Tanzania, children with malaria-associated anaemia are frequently given blood transfusions, and donor blood is not screened for hepatitis C virus (HCV) infection. To determine the seroprevalence of HCV infection in Tanzanian children previously transfused with blood, 184 children (92 transfused, 92 not transfused) aged between 15 and 59 months matched for age and sex were screened for HCV antibodies by the particle agglutination test using Serodia anti-HCV (Fujirebio Inc., Japan). The overall prevalence of HCV infection was 7.1% (13/184). HCV seropositivity was 5.4% (5/92) among children with a history of blood transfusion and 8.6% (8/92) among the non-transfused. There was no significant difference in the prevalence of HCV infection between transfused and non-transfused children. None of the factors investigated, such as gender, the nutrition and HIV serostatus of the children and the marital and education status of their mothers, was associated with HCV seropositivity. Further studies are recommended to identify the factors associated with HCV infection in Tanzanian children.

    1996-10-01

    This article reports the details of delayed hemolytic transfusion reactions in four patients with sickle cell disease. These cases demonstrate the characteristics of the reactions, the significant risks involved, and the principles useful in diagnosis and treatment. Patients with sickle cell disease are at particular risk for delayed hemolytic transfusion reactions because they may be transfused at intervals over many years; they frequently form alloantibodies because of antigenic differences from the donor population; and they may receive emergency care in different hospitals where transfusion records are not available. In addition, exchange transfusions, which are often used for patients with sickle cell disease and which were given in three of these cases, raise the risks through increased exposure to foreign erythrocyte antigens and through an increased volume of erythrocytes susceptible to hemolysis. It was concluded that the hazards of these transfusion reactions justify preventive measures, such as extended erythrocyte phenotyping of patients with sickle cell disease and extended phenotypic matching of transfused cells.

    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.

    Thalassaemia intermedia includes thalassaemias with clinical severity intermediate between asymptomatic thalassaemia minor and transfusion dependent thalassaemia major. By definition patients of thalassaemia intermedia maintain a haemoglobin level of 7-10 g/dl and do not, or only occasionally, require blood transfusion. An eight-year-old girl who was a known case of thalassaemia intermedia and had been occasionally transfused presented with fever, pain and swelling over the wrists, ankles and above the right knee joint. Radiographs showed medullary widening, cortical thinning and; multiple, recent and old, partially healed fractures of metadiaphseal regions of long bones. Her fractures have been immobilized by means of back slabs. In view of her recurrent fractures and growth retardation we advised a regular transfusion-chelation regimen to our patient to suppress her ineffective dyserythropoiesis. The treatment is expected to prevent further bone fragility and fractures, as well as improve her life quality. PMID:22125999

    Full Text Available Barbara Hauck-Dlimi, Susanne Achenbach, Julian Strobel, Reinhold Eckstein, Robert Zimmermann Department of Transfusion Medicine and Haemostaseology, University Hospital Erlangen, Erlangen, Germany Abstract: Transfusion of blood components, transplantations, and exchange of blood between mother and child during pregnancy or at birth can lead to alloimmunization. Because of its clinical relevance, this review brings into focus alloimmunization against red blood cells, human platelet antigens, human leukocyte antigens, and human neutrophil antigens. In principle, an individual is able to develop antibodies after exposure to a nonautogenous antigen, but these cells actually induce alloimmunization only for a minority of patients. An individual producing alloantibodies after having contact with foreign antigens depends on various factors, such as genetic predisposition, underlying diseases, the patient's immune status, and clinical immune modulation. When alloimmunization has occurred, it could lead to problems for future transfusions or transplantations. Keywords: transfusion, alloimmunization, prevention

    2014-01-01

    BACKGROUND: Blood transfusions are frequently given to patients with septic shock. However, the benefits and harms of different hemoglobin thresholds for transfusion have not been established. METHODS: In this multicenter, parallel-group trial, we randomly assigned patients in the intensive care...... unit (ICU) who had septic shock and a hemoglobin concentration of 9 g per deciliter or less to receive 1 unit of leukoreduced red cells when the hemoglobin level was 7 g per deciliter or less (lower threshold) or when the level was 9 g per deciliter or less (higher threshold) during the ICU stay...... were similar in the two intervention groups. CONCLUSIONS: Among patients with septic shock, mortality at 90 days and rates of ischemic events and use of life support were similar among those assigned to blood transfusion at a higher hemoglobin threshold and those assigned to blood transfusion...

  10. Cardiac iron across different transfusion-dependent diseases

    OpenAIRE

    Wood, John C.

    2008-01-01

    Iron overload occurs in patients who require regular blood transfusions to correct genetic and acquired anaemias, such as β-thalassaemia major, sickle cell disease, and myelodysplastic syndromes. Although iron overload causes damage in many organs, accumulation of cardiac iron is a leading cause of death in transfused patients with β-thalassaemia major. The symptoms of cardiac iron overload will occur long after the first cardiac iron accumulation, at a point when treatment is more complex th...

  15. Improved survival of newborns receiving leukocyte transfusions for sepsis

    International Nuclear Information System (INIS)

    To determine the role of polymorphonuclear (PMN) leukocyte transfusions in neonates with sepsis, 23 consecutive newborns were prospectively randomly selected during an 18-month period in a treatment plan to receive polymorphonuclear leukocyte transfusions with supportive care or supportive care alone. Thirteen neonates received transfusions every 12 hours for a total of five transfusions. Each transfusion consisting of 15 mL/kg of polymorphonuclear leukocytes was subjected to 1,500 rads of radiation. The polymorphonuclear leukocytes were obtained by continuous-flow centrifugation leukapheresis and contained 0.5 to 1.0 X 10(9) granulocytes per 15 mL with less than 10% lymphocytes. Positive findings on blood cultures were obtained in 14/23 patients and seven were randomly selected for each treatment group. Absolute granulocyte counts were less than 1,500/microL in 13 patients but tibial bone marrow examinations revealed that the neutrophil supply pool was depleted in only three patients. The survival was significantly greater in the treatment group compared with the group that did not receive transfusions

    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.

    Objective:Blood transfusion saves lives but may also increase the risk of injury.The objective of this review was to evaluate the possible adverse effects related to transfusion of red blood cell (RBC) concentrates stored for prolonged periods.Data Sources:The data used in this review were mainly from PubMed articles published in English up to February 2015.Study Selection:Clinical and basic research articles were selected according to their relevance to this topic.Results:The ex vivo changes to RBC that occur during storage are collectively called storage lesion.It is still inconclusive if transfusion of RBC with storage lesion has clinical relevance.Multiple ongoing prospective randomized controlled trials are aimed to clarify this clinical issue.It was observed that the adverse events related to stored RBC transfusion were prominent in certain patient populations,including trauma,critical care,pediatric,and cardiac surgery patients,which leads to the investigation of underlying mechanisms.It is demonstrated that free hemoglobin toxicity,decreasing of nitric oxide bioavailability,and free iron-induced increasing of inflammation may play an important role in this process.Conclusion:It is still unclear whether transfusion of older RBC has adverse effects,and if so,which factors determine such clinical effects.However,considering the magnitude of transfusion and the widespread medical significance,potential preventive strategies should be considered,especially for the susceptible recipients.

    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

    2010-01-01

    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

    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 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.

    Full Text Available Background: Despite progress made in the prevention of transfusion-transmitted infections (TTI over the last few years, they continue to be a problem in many parts of the world, particularly in multitransfused patients.Objectives: The aim of this study was to estimate the prevalence of hepatitis B virus (HBV, hepatitis C virus (HCV, and to evaluate the screening and vaccination program among our cohort of multitransfused children from Qena, Upper Egypt.Patients and Methods: One-hundred children suffering from diseases requiring repeated blood transfusions were included in the study. They were classified into group 1, which included 67 children with thalassemia, and group 2, which included 33 children with hemophilia. Screening for hepatitis B surface antigen, hepatitis B surface antibody, hepatitis B core antibody and antibody to HCV was done using a second-generation enzyme-linked immunosorbent assay technique.Results: Only 12% of all patients were either acutely or chronically infected with HBV. 46% were immune due to previous vaccination, whereas 39% of patients were not protected from HBV infection. HCV antibodies were positive in 45% of cases. Seventy-eight patients had a complete hepatitis B vaccination in the form of three doses as documented by birth certificate. Thirty-six patients mentioned history suggestive of hepatitis. The prevalence of the studied hepatitis markers was similar in both the thalassemia and hemophilia groups of children.Conclusions: Transfusion-transmitted hepatitis is still a major problem for multitransfused children in Egypt. More effort is required to reduce the infection rate through proper screening of blood and blood products, strict emphasis on receiving the vaccine, regular follow-up for those children with a hepatitis B antibody titer, and providing booster doses for those in need.

    Full Text Available Background: ABO incompatibility hemolytic disease of the newborn is a common cause of clinical jaundice and causes two-thirds of the hemolytic disease in newborns. This study was undertaken to determine the frequency of ABO incompatibility hemolytic disease and its complications in newborns undergoing exchange transfusion.Methods: This prospective and descriptive study was performed in jaundiced newborn infants during a three-year period. Inclusion criteria were: maternal blood type O, newborn blood type A or B, rising indirect hyperbilirubinemia in the first two days of life, positive immunohematologic test for newborns and exchange transfusion. Exclusion criteria were: incomplete information, other accompanying diseases that induce hyperbilirubinemia. All newborn infants received phototherapy before and after exchange transfusion. We did not use intravenous immunoglobulin, hemoxygenase inhibitor drugs and blood products before exchange transfusion.Results: Double-volume exchange transfusion via umbilical cord catheter was performed in 96 patients, 19 (20% of whom suffered from ABO incompatibility. Of these 19 newborns, two-thirds (13 were preterm infants. The minimum level of serum bilirubin was 10 mg/dl and the maximum serum bilirubin level was 35 mg/dl. In six patients (32% serum bilirubin levels were >25mg/dl. The most common blood group was type A for newborns. Immunohematologic tests were positive in 84% of the mothers. ABO incompatibility hemolytic disease was the fourth and second most common reasons for blood exchange transfusion in preterm and term infants, respectively. Laboratory complications were more common than clinical complications. The etiology of 48% of the alloimmunization and 42% of the hemolytic disease in these newborns was ABO incompatibility.Conclusions: Mothers with blood group O and newborns with blood group A or B with positive immunohematologic tests in first hours of life are at high risk for hemolytic disease

    2003-01-01

    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.

    The bacterial transfusion risk is currently the greatest infectious risk of blood transfusion. We report the case of a child with postchemotherapy febrile neutropenia who presented septic shock following platelet transfusion contaminated with Citrobacter koseri. The life-threatening development could have been avoided by strict compliance with good clinical practice. The stability of mortality rates due to adverse effects of bacterial proliferation during platelet transfusions in France since 1994 calls for optimization of all preventive measures throughout the transfusion chain and perfect knowledge of transfusion rules by medical staff and care givers.

    Full Text Available Abstract Background The Leiden University Medical Center (LUMC is the Dutch national referral centre for pregnancies complicated by haemolytic disease of the fetus and newborn (HDFN caused by maternal alloimmunization. Yearly, 20-25 affected fetuses with severe anaemia are transfused with intra-uterine blood transfusions (IUT. Mothers of whom their fetus has undergone IUT for HDFN are considered high responders with regard to red blood cell (RBC antibody formation. Most study groups report high perinatal survival, resulting in a shift in attention towards short- and long-term outcome in surviving children. Methods/Design We set up a large long-term observational follow-up study (LOTUS study, in cooperation with the Sanquin Blood Supply Foundation and the LUMC departments of Obstetrics, Neonatology and ImmunoHematology & Bloodtransfusion. The first part of this study addresses several putative mechanisms associated with blood group alloimmunization in these mothers. The second part of this study determines the incidence of long-term neurodevelopment impairment (NDI and associated risk factors in children treated with IUT. All women and their life offspring who have been treated with IUT for HDFN in the LUMC from 1987-2008 are invited to participate and after consent, blood or saliva samples are taken. RBC and HLA antigen profile and antibodies are determined by serologic or molecular techniques. Microchimerism populations are tested by real time polymerase chain reaction (RT PCR. All children are tested for their neurological, cognitive and psychosocial development using standardised tests and questionnaires. The primary outcome is neurodevelopmental impairment (NDI, a composite outcome defined as any of the following: cerebral palsy, cognitive or psychomotor development Discussion The LOTUS study includes the largest cohort of IUT patients ever studied and is the first to investigate post-IUT long-term effects in both mother and child.

    Frequent blood transfusions can lead to iron overload which may result in several endocrine complications especially in the absence of adequate chelation therapy. The objectives of this study are to determine the prevalence of endocrine complications in transfusion dependent thalassaemia patients and the correlation of endocrine complications with the degree of iron chelation. This retrospective study looked at cases of adult patients with transfusion dependent thalassaemia treated in the Haematology Unit, Penang Hospital. Of the 25 transfusion dependent thalassaemia patients, there were 10 male and 15 female patients respectively with almost equal number of Malay and Chinese patients (13 and 12 patients respectively). Short stature was seen in 36.0% of our patients. In our cohort, 12 patients had delayed puberty (male 70.0% and female 33.3%). Prevalence of osteoporosis was 36.0%. Hypogonadism was noted in 40.0% of males and 46.7% of females. 53.4% of the female population had menstrual abnormalities with prevalence of primary and secondary amenorrhoea at 26.7% each. The prevalence of other endocrinopathies was much lower: 8.0% had diabetes mellitus and only one patient had hypocortisolism. Iron chelation appeared insufficient in our study population. The high frequency of endocrine complications noted in our study supports the rationale for regular follow-up of transfusion dependent thalassaemic patients to ensure early detection and timely treatment of associated complications.

    2010-12-01

    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 Transfusion transmitted infections are major problem associated with blood transfusion. Accurate estimates of risk of TTIs are essential for monitoring the safety of blood supply and evaluating the efficacy of currently employed screening procedures. The present study was carried out to assess the percentage of voluntary donors and replacement donors and to find out prevalence and changing trends of various TTIs blood donors in recent years. A study was carried out on blood units of voluntary and replacement donors which were collected from January 2008 to December 2012. On screening of 180,371 replacement units, seropositivity of transfusion transmitted disease in replacement donors was 0.15% in HIV, 1.67% in hepatitis B surface antigen, 0.49% in hepatitis C virus, 0.01% in VDRL, and 0.009% in malaria. Of 11,977 voluntary units, seropositivity of transfusion transmitted disease in voluntary donors was 0.08% in HIV, 0.24% in hepatitis B surface antigen, 0.001% in hepatitis C virus, 0.008% in VDRL (sexually transmitted disease, and 0.01% in malaria. From results it has been concluded that prevalence of transfusion transmitted infection (HIV, HBV, HCV, VDRL, and malaria was more in replacement donors in comparison to voluntary donors. Extensive donor selection and screening procedures will help in improving the blood safety.

    Stored platelets undergo biochemical, structural and functional changes that lead to decreased efficacy and safety of platelet transfusions. Not only do platelets acquire markers of activation during storage, but they also fail to respond normally to agonists post-storage. We hypothesized that resveratrol, a cardioprotective antioxidant, could act as a novel platelet storage additive to safely prevent unwanted platelet activation during storage, while simultaneously preserving normal haemostatic function. Human platelets treated with resveratrol and stored for 5 d released less thromboxane B2 and prostaglandin E2 compared to control platelets. Resveratrol preserved the ability of platelets to aggregate, spread and respond to thrombin, suggesting an improved ability to activate post-storage. Utilizing an in vitro model of transfusion and thromboelastography, clot strength was improved with resveratrol treatment compared to conventionally stored platelets. The mechanism of resveratrol's beneficial actions on stored platelets was partly mediated through decreased platelet apoptosis in storage, resulting in a longer half-life following transfusion. Lastly, an in vivo mouse model of transfusion demonstrated that stored platelets are prothrombotic and that resveratrol delayed vessel occlusion time to a level similar to transfusion with fresh platelets. We show resveratrol has a dual ability to reduce unwanted platelet activation during storage, while preserving critical haemostatic function. PMID:26683619

    Full Text Available Despite major advances in Brazilian blood transfusion therapy with a growing number of scientific publications, an increased number of repeat donors and a decline in serological ineligibility, a lack of conformity in the application of pre-transfusion tests that may compromise transfusion safety is still observed at transfusion agencies in the fringes of the blood transfusion therapy system. Additionally, although high rates of platelet transfusion refractoriness and significant rates of alloimmunization have been demonstrated in the international literature, few Brazilian centers have been concerned with the study of platelet alloimmunization and even fewer centers have evaluated the efficacy of platelet concentrate transfusion. As more than one million Brazilians, including many repeat blood donors, are listed in the National Bone Marrow Donor Registry (Redome, why not grant transfusion therapy services access to the HLA typing of these blood and marrow donors after obtaining their consent? And why not make use of the Redome data to evaluate the HLA compatibility of donors for alloimmunized patients who are candidates for bone marrow transfusion and who have already been typed? These measures, together with the identification of ABO and HPA antigens, will permit a complete assessment of platelet immunology, will guarantee the transfusion safety of this blood component, and will put Brazil at the same level as the so-called developed countries in terms of transfusion medicine.

    Late presentation and ineffective phototherapy account for excessive rates of avoidable exchange transfusions (ETs) in many low- and middle-income countries. Several system-based constraints sometimes limit the ability to provide timely ETs for all infants at risk of kernicterus, thus necessitating a treatment triage to optimize available resources. This article proposes a practical priority-setting model for term and near-term infants requiring ET after the first 48 h of life. The proposed model combines plasma/serum bilirubin estimation, clinical signs of acute bilirubin encephalopathy and neurotoxicity risk factors for predicting the risk of kernicterus based on available evidence in the literature.

    Results: Out 50 patients of thalassemia major, 4 patients (8% developed red cell alloantibodies respectively. The red cell alloantibodies were against Rh, Kidd, Kell, Duffy, Lewis, MNS and P system. Results of this study (P value >0.05 indicate low frequency of RBCs alloimmunization. Conclusions: Low alloimmunization rate implies that there is homogeneity of red cell antigens in blood donors and recipients. RBCs alloantibody formation was not influenced by gender, age at start of transfusions and number of packed cells received. Already alloimmunized patients get benefits from leucodepleted packed cells. Specific recommendation given on routine pre-transfusion antibody screening to ensure safer transfusion.

    2016-01-01

    This article examines medical discourse surrounding the first animal-to-human blood transfusion performed in 1667 by the French physician Jean-Baptiste Denis. During this period, new physiologies interacted with Galenic medicine in various social milieus that shaped discourse over the body. Although the practice of transfusion was based in contemporary theories of circulation, the therapeutic rationale for transfusion largely appealed to Galenic humouralism. This case reveals how social and intellectual contexts engendered an eclectic corporality, which integrated contemporary natural philosophy within a framework of medical Galenism. Medical discourse from this episode suggests a pluralistic conception of the body--a body that was broadly humoural but included accretions from new physiologies. PMID:27344904

    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.

    The centenary of the start of the First World War has stirred considerable interest in the political, social, military and human factors of the time and how they interacted to produce and sustain the material and human destruction in the 4 years of the war and beyond. Medical practice may appear distant and static and perhaps seems to have been somewhat ineffectual in the face of so much trauma and in the light of the enormous advances in medicine and surgery over the last century. However, this is an illusion of time and of course medical, surgical and psychiatric knowledge and procedures were developing rapidly at the time and the war years accelerated implementation of many important advances. Transfusion practice lay at the heart of resuscitation, and although direct transfusion from donor to recipient was still used, Geoffrey Keynes from Britain, Oswald Robertson from America and his namesake Lawrence Bruce Robertson from Canada, developed methods for indirect transfusion from donor to recipient by storing blood in bottles and also blood-banking that laid the foundation of modern transfusion medicine. This review explores the historical setting behind the development of blood transfusion up to the start of the First World War and on how they progressed during the war and afterwards. A fresh look may renew interest in how a novel medical speciality responded to the needs of war and of post-war society.

    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.

    This study was purposed to explore the suitable ratio between fresh frozen plasma and erythrocyte by retrospective analysis of coagulation in patients with massive blood transfusion. The clinical data of 151 cases with massive blood transfusion from January 2011 to January 2013 were analyzed retrospectively. According to coagulation, patients were divided into coagulation normal group (138 cases) and coagulation dysfunction group (13 cases). Based on the ratio of 1:1 of fresh frozen plasma and erythrocyte, the patients were divided into high plasma group(2:1), medium plasma group (1:1) and low plasma (transfusion. The results showed that prothrombin time (PT), activated partial thromboplastin time (APTT) and thrombin time (TT) were prolonged, fibrinogen (FIB) level decreased significantly (all P transfusion 24 h; the high plasma and the medium plasma group of coagulation normal group had no significant changes in coagulation (P > 0.05); prothrombin time, activated partial thromboplastin time, thrombin time and fibrinogen level in the medium plasma and low plasma subgroup of coagulation dysfunction group after massive transfusion was still in abnormal levels (P > 0.05), coagulation function in high plasma subgroup was improved significantly (P transfusion, the ratio between fresh frozen plasma and erythrocyte is recommended to be 2:1 in patients of coagulation dysfunction in order to improve the patient's coagulation function and to reduce the incidence of adverse event, the ratio of fresh frozen plasma to erythrocyte is recommended to be 1:1 in patients with normal coagulation so as to reduce the dilutional coagulopathy and hypervolemia of blood.

    2002-06-01

    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.

    Full Text Available Introduction: Red cell allo- and auto-immunization is a well recognized problem in multi-transfused thalassemic patients. We conducted this study on 301 multi-transfused thalassemic patients under the Thalassemia Transfusion Programme of Advanced Pediatric Centre of PGIMER. Aims and Objectives: The study was designed to determine the frequency of alloimmunization and autoimmunization in multi-transfused thalassemic patients and to establish the specificity of alloantibody to red cell antigens, if alloimmunization is detected. Materials and Methods: The antibody screening was performed by the conventional tube technique using commercially available three cell screening panel (Diamed Switzerland by saline, low ionic strength solution (LISS and albumin indirect antiglobulin test (IAT. Samples with alloantibodies were then tested with red cell identification panel to determine the alloantibody specificity. Autoantibody screening was performed by direct antiglobulin test (DAT during pre-transfusion testing. Results: Of the 301 patients, 52 (17.28% were found to have antibodies (-allo and –autoantibodies. A total of 11 red cell alloantibodies were detected in 10 patients and the specificities were anti-Kell in 6(54.5%, anti-D in 2(18.2%, anti-c in 1(9.1% and a combination of anti-E (9.1% and anti-Jkb in 1 (9.1% patients. DAT was positive in 48 (15.9% patients. The frequency of autoantibody was significantly higher in alloimmunized group as compared to non-alloimmunized group (60% V/s 14.4%. Also, the pre-transfusion hemoglobin was significantly lower in the immunized group (8.5 gm/dl V/s 9.0 gm/dl; p=0.03 than the non-immunized group. Conclusion: Based on these observations, we suggest antigen typing of all thalassemia major patients for ABO, Rh and Kell antigens before initiating transfusion therapy. Also, screening for allo- and auto-antibodies at regular intervals should be done prior to each transfusion.

    Transfusion-transmitted infections including hepatitis B virus (HBV) have been a major concern in transfusion medicine. Implementation of HBV nucleic acid testing (NAT) has revealed occult HBV infection (OBI) in blood donors. In the mid-1980s, hepatitis B core antibody (HBc) testing was introduced to screen blood donors in HBV non-endemic countries to prevent transmission of non-A and non-B hepatitis.

    Full Text Available Babesiosis, a common disease of animals, can infect humans via vector “tick bite”, particularly in endemic areas. The recent reports of fatal cases in Hepatitis C and postliver transplant patients resulting from transfusion of contaminated blood should alert the medical profession regarding this emerging dilemma in endemic as well as nonendemic areas and the need for accurate blood screening for transfusion. Here, we illustrate different stages of the parasite lifecycle, progression of babesiosis in animal model, some aspects of pathologic outcomes, ongoing therapeutic modalities, and a feasible Acridine Orange fluorescent methodology for the diagnostic evaluation of blood samples.

    Full Text Available Background: Serological safety is an integral part of overall safety for blood banks. Emphasis is on the use of routinue Red Blood Cell (RBC antibody screen test, at set time intervals, to reduce risks related to alloantibodies. Also emphasis is on importance of issuing antigen negative blood to alloantibody positive patients. Effect of using leucodepleted blood on the rate of alloimmunization is highlighted. The concept of provision of phenotypically matched blood is suggested. Materials and Methods: Antibody screen test is important to select appropriate blood for transfusion. Repeat antibody screen testing, except if time interval between the earlier and subsequent transfusion was less than 72 hours, followed by antibody identification, if required, was performed in patients being treated with repeat multiple blood transfusions. Between February 2008 and June 2009, repeat samples of 306 multi-transfused patients were analyzed. Search for irregular antibodies and reading of results was conducted using RBC panels (three-cell panel of Column Agglutination Technology (CAT and two cell panel of the Solid Phase Red Cell Adherence Technology (SPRCAT. Specificities of antibodies were investigated using appropriate panels, 11 cell panel of CAT and 16 cell panel of SPRCA. These technologies, detecting agglutination in columns and reactions in solid phase, evaluate the attachment of irregular incomplete antibody to antigen in the first phase of immunological reaction more directly and hence improve the reading of agglutination. Three to four log leuco reduced red blood cells were transfused to patients in the study using blood collection bags with integral filters. Results: Alloimmunization rate of 4.24% was detected from 306 multiply transfused patients tested and followed up. The Transfusion therapy may become significantly complicated. Conclusion: Red cell antibody screening and identification and subsequent issue of antigen negative blood have a

  6. Toward a patient-based paradigm for blood transfusion

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

  7. The use of big data in transfusion medicine.

    'Big data' refers to the huge quantities of digital information now available that describe much of human activity. The science of data management and analysis is rapidly developing to enable organisations to convert data into useful information and knowledge. Electronic health records and new developments in Pathology Informatics now support the collection of 'big laboratory and clinical data', and these digital innovations are now being applied to transfusion medicine. To use big data effectively, we must address concerns about confidentiality and the need for a change in culture and practice, remove barriers to adopting common operating systems and data standards and ensure the safe and secure storage of sensitive personal information. In the UK, the aim is to formulate a single set of data and standards for communicating test results and so enable pathology data to contribute to national datasets. In transfusion, big data has been used for benchmarking, detection of transfusion-related complications, determining patterns of blood use and definition of blood order schedules for surgery. More generally, rapidly available information can monitor compliance with key performance indicators for patient blood management and inventory management leading to better patient care and reduced use of blood. The challenges of enabling reliable systems and analysis of big data and securing funding in the restrictive financial climate are formidable, but not insurmountable. The promise is that digital information will soon improve the implementation of best practice in transfusion medicine and patient blood management globally.

    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.

    A fatal case of transfusion-associated graft-versus-host disease developed in a premature infant after receiving several blood products, including nonirradiated white blood cells. Transfusion-associated graft-versus-host disease can be prevented. Irradiation of blood products is the least controversial and most effective method. Treatment was unsuccessful in most reported cases of transfusion-associated graft-versus-host disease. Therefore irradiation of blood products before transfusing to patients susceptible to transfusion-associated graft-versus-host disease is strongly recommended

    Full Text Available Platelet transfusion has been a vital therapeutic approach in patients with hematologic malignancies for close to half a century. Randomized trials show that prophylactic platelet transfusions mitigate bleeding in patients with acute myeloid leukemia. However, even with prophylactic transfusions, as many as 75% of patients experience hemorrhage. While platelet transfusion efficacy is modest, questions and concerns have arisen about the risks of platelet transfusion therapy. The acknowledged serious risks of platelet transfusion include viral transmission, bacterial sepsis, and acute lung injury. Less serious adverse effects include allergic and non-hemolytic febrile reactions. Rare hemolytic reactions have occurred due to a common policy of transfusing without regard to ABO type. In the last decade or so, new concerns have arisen; platelet derived lipids are implicated in transfusion related acute lung injury after transfusion. With the recognition that platelets are immune cells came the discoveries that supernatant IL-6, IL-27 sCD40L, and OX40L are closely linked to febrile reactions and sCD40L with acute lung injury. Platelet transfusions are pro-inflammatory, and may be pro-thrombotic. Anti-A and anti-B can bind to incompatible recipient or donor platelets and soluble antigens, impair hemostasis and thus increase bleeding. Finally, stored platelet supernatants contain biological mediators such as VEGF and TGF-β1 that may compromise the host versus tumor response. This is particularly of concern in patients receiving many platelet transfusions, as for acute leukemia. New evidence suggests that removing stored supernatant will improve clinical outcomes.This new view of platelets as pro-inflammatory and immunomodulatory agents suggests that innovative approaches to improving platelet storage and pre-transfusion manipulations to reduce toxicity could substantially improve the efficacy and safety of this long employed therapy.

    This study was purposed to explore whether the blood transfusion of surgical patients can increase the severity of postoperative infection by a retrospective analysis of patients with postoperative infection in Chinese PLA General Hospital. By using a software "clinical transfusion database" developed by our department, 150 infected surgical cases were retrieved and divided into deep infection group and superficial infection group according to the infected location. These two groups were compared in term of the patient's age, duration of hospitalization, red blood cell transfusion volume, none-red cell transfusion volume, transfusion frequency and average transfusion volume. The results showed that red blood cell transfusion volume or none-red cells transfusion volume of patients with superficial infection was 4.50 (0 - 59) U or 2.95 (0 - 119.6) U, and that of deep infection was 9.00 (0 - 153) U and 8.05 (0 - 136.6) U, the differences was significant (P transfusion frequency showed the most significant difference, median in the patients with superficial infection was about 2 (1 - 31) times, less than the deep infection group about 4 (1 - 49) times (P transfusion volume. It is concluded that perioperative blood transfusion volume and frequency of surgical patients seems to display a positive correlation with the degree of postoperative infection.

    Full Text Available Transfusions are a cause of significant patient morbidity as well as expense. Anesthesia literature has examined controlled intraoperative hypotension as a means for reducing blood loss and transfusions. Our hypothesis is that inversely increased blood pressure post-operatively would then lead to increased blood loss and transfusions.We examined 105 consecutive patients who underwent TKA. We found a significant odds ratio of 1.123 for pre-operative hematocrit. For post-operative blood pressure, we calculated an insignificant odds ratio of 1.007, proving no relationship between post-operative blood pressure and transfusions.This is the first study to examine increased post-operative blood pressure's contribution to transfusion rates. Although we confirmed that low pre-operative hematocrit contributes to increased transfusions, we did not find a relationship between post-operative blood pressure and transfusions.

    Full Text Available Twin-twin transfusion syndrome is a serious complication of monozygotic, monochorionic, diamniotic twins resulting from transplacental vascular communications. In this syndrome blood is thought to be shunted from one twin - donor,who develops anaemia,growth retardation and oligoamnios, to the other twin - recipient,who becomes plethoric,macrosomic and develops polyhydroamnios. The incidence of twin-twin transfusion syndrome ranges from 5-15% of all twin pregnancies. If this condition develops in the second trimester, it is usually associated with spontaneous abortion and death of one or both fetuses before viability. Developing the syndrome in the third trimester has better perinatal outcome. Mortality rates ranging from 56%-100%, depending on gestational age and severity of the syndrome. The ultrasound criterias for diagnosis, in this study,were the presence of twins of the same sex with discordant growth, with oligohydroamnios in one twin sac and polyhydroamnios in the other one, one placenta and thin membrane between twins. The present study shows clinical course of 14 cases and value of Doppler ultrasound to analyze the usefulness of umbilical artery blood flow velocimetry for predicting the risk of twin-twin transfusion syndrome. 14 twin pregnancies with twin-twin transfusion syndrome were diagnosed during the last four years period and prospectivelly followed. 9 cases were diagnosed before the completion od 28 weeks of gestation.The mean gestational age was 21,6_+4,2 weeks at diagnosis and 23,2+_3,6 weeks at delivery. 5 cases were diagnosed after 28 weeks of gestation.

    The safety of blood transfusion depends on a country's laws, decrees and/or regulations concerning the collection, production and use of blood and blood derivatives. It also needs governmental enforcement of those instruments, as well as trained health professionals to obtain blood and produce blood derivatives, following total quality control procedures both at collection and production, and use. By 1998, all Latin American countries had laws, decrees and/or regulations that governed the production and use of blood, with the exception of El Salvador and Nicaragua. During the past six decades, economic need in Latin America has promoted migration to urban areas. Consequently, at present time, more than 60% of the population live in cities, which increases the probability of finding blood infected by Trypanosoma cruzi among donors. Unless all the blood from infected donors is discarded, the possibility of transmitting infection by transfusion remains. Moreover, infection by T. cruzi through transfusion is a potential problem in developed countries, now that tens of thousands of individuals from Latin America have migrated to the United States, Canada, western Europe, Australia and Japan. When donors are not screened for T. cruzi, the risk of transfusing infected blood is greater at higher prevalence rates of infection in the donor population; it also increases with the number of transfusions received by the recipient. In 1993, Bolivia presented the highest risk of receiving infected blood and becoming infected with T. cruzi; this country was followed by Colombia, El Salvador and Paraguay. As the coverage of HIV screening became almost universal, the probability of receiving blood infected by HIV and becoming infected was low in all countries. In the case of hepatitis B (HVB), the highest probability of infection was in Bolivia, Nicaragua and Guatemala. This probability was even greater for Hepatitis C (HVC), given the low coverage of donor screening in all countries

    A 53-year-old white man had fever, malaise, and dyspnea on exertion. His chest roentgenogram was normal, but pulmonary function tests showed impaired diffusion capacity and a gallium scan showed marked uptake in the lungs. Results of an open-lung biopsy documented Pneumocystis carinii pneumonia. Immunologic test results were consistent with the acquired immunodeficiency syndrome. The patient denied having homosexual contact or using intravenous drugs. Twenty-nine months before the diagnosis of pneumocystis pneumonia was made, the patient had had 16 transfusions of whole blood, platelets, and fresh-frozen plasma during coronary artery bypass surgery at another medical center. This patient is not a member of any currently recognized high-risk group and is believed to have contracted the acquired immunodeficiency syndrome from blood and blood-product transfusions.

    This article examines the association between blood transfusions in developing countries and the transmission of HIV/AIDS. The safety of a blood transfusion in a developing country depends upon the hospital, the city, and the country. It is possible to have a safe supply of donor blood even in countries with a 5-10% prevalence of HIV/AIDS. The maintenance of a high-quality blood supply is dependent upon blood volunteers, government funding of blood services, adequate supervision of commercial blood supplies, and professionals who collect, test, and supply safe blood. A World Health Organization (WHO) paper on Accelerated Strategies to reduce the risk of transmission of HIV by blood transfusion (1989) sets forth three recommendations: 1) the promotion of voluntary, unpaid for blood donations from low risk groups; 2) the determination of HIV screening policies at a national level using single, rapid, and reliable tests with proper quality assurance; and 3) the establishment of national advisory committees. Safe donors in low-risk groups are easily recruited in countries with acceptance of blood donations, known safe blood donations, and concentration of AIDS among identifiable high risk groups. The WHO paper on Minimum Targets for Blood Transfusion Services (1989) gives recommendations regarding long-term problems with donor recruitment. Donor selection must be consistent and reliable. Payment should not accompany donations at any point. Political, religious, and cultural leaders should be enlisted for public support. Recipients should receive a limited supply of blood. The selection of inappropriate tests for HIV are the cause of most false reactions. There is a need to define a simple blood-banking package that specifies equipment, consumables, data-handling capacity, and human skills needed for setting up and maintaining working banks in major hospital centers that provide pediatric, obstetric, and surgical services.

    The H-deficient phenotypes found in Chinese so far, have all been secretors of soluble blood group substances in saliva. The corresponding isoagglutinin activity (e.g. anti-B in OB(Hm) persons) has been found to be weak in all cases. To determine the clinical significance of these weak isoagglutinins 51Cr red cell survival tests were performed on three OB(Hm) individuals transfused with small volumes (4 ml) of groups B and O RBC. Rapid destruction of most of the RBC occurred whether or not the isoagglutinins of the OB(Hm) individuals were indirect antiglobulin test (IAGT) reactive. When a larger volume (54 ml packed RBC) of group B cells (weakly incompatible by IAGT) was transfused to another OB(Hm) individual with IAGT active anti-HI, the survival of the transfused RBC was 93% at 24 h, with 30% of the RBC remaining in the circulation at 28 d in contrast to 76% as would be expected if the survival was normal. Therefore when whole units of blood of normal ABO blood groups, compatible by IAGT, are transfused, the survival is expected to be almost normal. These weak isoagglutinins may not be very clinically significant and we suggest that when para-Bombay blood is not available, the compatibility testing for OA(Hm) persons should be performed with group A and group O packed RBC; OB(Hm) with group B and group O packed RBC: OAB(Hm) with groups A, B, AB and O packed RBC. For cross matching, the indirect antiglobulin test by a prewarmed technique should be used.

    This article examines the association between blood transfusions in developing countries and the transmission of HIV/AIDS. The safety of a blood transfusion in a developing country depends upon the hospital, the city, and the country. It is possible to have a safe supply of donor blood even in countries with a 5-10% prevalence of HIV/AIDS. The maintenance of a high-quality blood supply is dependent upon blood volunteers, government funding of blood services, adequate supervision of commercial blood supplies, and professionals who collect, test, and supply safe blood. A World Health Organization (WHO) paper on Accelerated Strategies to reduce the risk of transmission of HIV by blood transfusion (1989) sets forth three recommendations: 1) the promotion of voluntary, unpaid for blood donations from low risk groups; 2) the determination of HIV screening policies at a national level using single, rapid, and reliable tests with proper quality assurance; and 3) the establishment of national advisory committees. Safe donors in low-risk groups are easily recruited in countries with acceptance of blood donations, known safe blood donations, and concentration of AIDS among identifiable high risk groups. The WHO paper on Minimum Targets for Blood Transfusion Services (1989) gives recommendations regarding long-term problems with donor recruitment. Donor selection must be consistent and reliable. Payment should not accompany donations at any point. Political, religious, and cultural leaders should be enlisted for public support. Recipients should receive a limited supply of blood. The selection of inappropriate tests for HIV are the cause of most false reactions. There is a need to define a simple blood-banking package that specifies equipment, consumables, data-handling capacity, and human skills needed for setting up and maintaining working banks in major hospital centers that provide pediatric, obstetric, and surgical services.

    Full Text Available Introduction. Red blood cell antibodies may cause a positive result of pre-transfusion blood compatibility testing (crossmatch test. It can be a problem to provide suitable blood units for patients with clinically significant antibodies to high-frequency antigens as well as for those with multiple alloantibody specificities. This study was aimed at identifying transfused patients in the population of South-Backa who had developed clinically significant red blood cell alloantibodies. Material and methods. We analyzed the records of crossmatch results and antibody screening performed at the Blood Transfusion Institute of Vojvodina during 2012. Results. 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.

    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.

    Limiting blood transfusion in cardiac operations is a well-meaning goal of perioperative care. Potential benefits include decreasing morbidity and limiting procedural costs. It is difficult to identify transfusion as the cause of adverse outcomes. The need for transfusion may identify a sicker patient population at greater risk for a worse outcome that may or may not be related to the transfusion. We reviewed the indications for and adverse effects of blood transfusion in patients undergoing cardiac procedures to provide a balanced approach to management of blood resources in this population. We reviewed current literature, including systematic reviews and practice guidelines, to synthesize a practice management plan in patients having cardiac operations. Several prospective randomized studies and large population cohort studies compared a postoperative restrictive transfusion policy to a more liberal policy and found very little difference in outcomes but decreased costs with a restrictive policy. Evidence-based practice guidelines and implementation standards provide robust intervention plans that can limit harmful effects of transfusion and provide safe and effective procedure outcomes. A restrictive transfusion policy seems to be safe and effective but does not necessarily provide better outcome in most patient cohorts. The implications of these findings suggest that many discretionary transfusions could be avoided. A subset of high-risk patients could undoubtedly benefit from a more liberal transfusion policy, but the definition of high risk is ill defined. PMID:27532302

    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.

    Necrotizing enterocolitis (NEC) is a disease primarily of prematurity characterized by partial or entire gut necrosis and is associated with significant mortality and morbidity. Recent studies report that approximately 25% to 35% of very low-birth-weight infants less than 1500 g receiving packed red blood cell transfusions develop temporally associated NEC, known as transfusion-related NEC (TR-NEC). Although there are many known risk factors for NEC, this article focuses on 3 contributing factors: packed red blood cell transfusions, enteral feedings, and gastrointestinal immaturity. Previous data suggest that these factors may interact to affect neonatal intestinal tissue oxygenation, which may lead to tissue ischemia, resulting in intestinal injury. This article presents a conceptual framework that combines current theoretical perspectives for TR-NEC, and reviews previous research examining related variables and how their interaction may increase the risk for TR-NEC development. In addition, incorporation of the proposed framework to guide future research and nursing care in this area is discussed.

    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.

    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.

We will focus on corollary benefits with the use of HemaClear®, a self-contained, sterile, exsanguinating auto-transfusion tourniquet. This discussion will demonstrate that the use of auto-transfusion tourniquets is a practical evidence-based approach in fluid resuscitation: it shortens the duration of shock after hemorrhage and trauma compared with conventional tourniquets. Emphasis is placed on the use of the HemaClear® as an alternative fluid resuscitation tool which is more efficient in the battlefield, pre-hospital and in-hospital settings.Keywords: auto-transfusion tourniquet, field exsanguination, hemorrhagic shock, tourniquet, perfusion requirement, HemaClear® ATT

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

    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.

    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.

    Platelet concentrates account for near 10% of all labile blood components but are responsible for more than 25% of the reported adverse events. Besides factors related to patients themselves, who may be particularly at risk of side effects because of their underlying illness, there are aspects of platelet collection and storage that predispose to adverse events. Platelets for transfusion are strongly activated by collection through disposal equipment, which can stress the cells, and by preservation at 22 °C with rotation or rocking, which likewise leads to platelet activation, perhaps more so than storage at 4 °C. Lastly, platelets constitutively possess a very large number of bioactive components that may elicit pro-inflammatory reactions when infused into a patient. This review aims to describe approaches that may be crucial to minimising side effects while optimising safety and quality. We suggest that platelet transfusion is complex, in part because of the complexity of the "material" itself: platelets are highly versatile cells and the transfusion process adds a myriad of variables that present many challenges for preserving basal platelet function and preventing dysfunctional activation of the platelets. The review also presents information showing--after years of exhaustive haemovigilance--that whole blood buffy coat pooled platelet components are extremely safe compared to the gold standard (i.e. apheresis platelet components), both in terms of acquired infections and of immunological/inflammatory hazards.

    AIM: To explore the biological behaviors of hepatic oval cells after transfused into the circulation of experimental animals.METHODS: Oval cells from male SD rat were transfused into the circulation of a female rat which were treated by a 2-AAF/CCl4 program, through caudal vein. Sex-determining gene sry which located on Y chromosome was examined by PCR and in situ hybridization technique in liver, kidney and spleen of the experimental animals, respectively.RESULTS: The results of the cell-transplant experiment showed that the srygene was detectable only in the liver but not in spleen and kidney of the experimental rats, and no signals could be detected in the control animals. It can be also morphologically proved that some exogenous cells had migrated into the parenchyma of the liver and settled there.CONCLUSION: The result means that there are exogenous cells located in the liver of the experimental animal and the localization is specific to the liver. This indicates that some "signal molecules" must exist in the circulation of the rats treated by 2-AAF/CCl4. These "signal molecules" might play an important role in specific localization and differentiation of transfused oval cells.

  8. Recombinant human erythropoietin and blood transfusion in low-birth weight preterm infants under restrictive transfusion guidelines

    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)

    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.

    Interpretation & conclusion: Platelet transfusion was required in children with severe dengue infection in the form of significant spontaneous bleed, shock and severe thrombocytopenia. Bleeding should not be considered only indicator to transfuse platelets as it occurred in children even with normal platelet counts. The community and treating physicians should be educated regarding the judicious transfusion of platelets. Unnecessary and empirical use of platelets should be completely avoided especially during an epidemic when there is scarcity in its availability.

    The current definition of massive transfusion is replacement of 5 U of packed red blood cells in 3 hours because of uncontrolled hemorrhage or replacement of the entire blood volume within a 24-hour period. The prompt activation of a transfusion protocol can quickly restore hemodynamic stability. Effective teamwork and communication is critical for a favorable patient outcome. This case study demonstrates the effectiveness of using a massive transfusion protocol in an outpatient setting. PMID:26137761

  17. Post-operative auto-transfusion in total hip or knee arthroplasty: a meta-analysis of randomized controlled trials.

    Zhao Haien

    Full Text Available BACKGROUND: Total hip or knee arthroplasty is an elective procedure that is usually accompanied by substantial blood loss, which may lead to acute anemia. As a result, almost half of total joint arthroplasty patients receive allogeneic blood transfusions (ABT. Many studies have shown that post-operative auto-transfusion (PAT significantly reduces the need for ABT, but other studies have questioned the efficacy of this method. METHODS: The protocol for this trial and supporting CONSORT checklist are available as supporting information; see Checklist S1. To evaluate the efficacy of PAT, we conducted a Cochrane systematic review that combined all available data from randomized controlled trials. Data from the six included trials were pooled for analysis. We then calculated relative risks with 95% confidence intervals (CIs for dichotomous outcomes and mean differences with 95% CIs for continuous outcomes. FINDINGS AND CONCLUSION: To our knowledge, this is the first meta-analysis to compare the clinical results between PAT and a control in joint replacement patients. This meta-analysis has proven that the use of a PAT reinfusion system reduced significantly the demand for ABT, the number of patients who require ABT and the cost of hospitalization after total knee and hip arthroplasty. This study, together with other previously published data, suggests that PAT drains are beneficial. Larger, sufficiently powered studies are necessary to evaluate the presumed reduction in the incidence of infection as well as DVT after joint arthroplasty with the use of PAT.

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%. Six (4% women died; mortality was due to renal failure in 3/6 (50% and disseminated intravascular coagulopathy in 3/6 (50%. These deaths were due to delays and difficulty in securing blood for transfusion, while those who got transfused on time were salvaged with minimal morbidity, 21/151 (14%, or with no morbidity, 130/151 (86%. Conclusion: Excessive blood loss and anemia still

    Bombay phenotype is extremely rare in Caucasian with an incidence of 1 in 250,000. When individuals with the Bombay phenotype need blood transfusion, they can receive only autologous blood or blood from another Bombay blood group. Transfusing blood group O red cells to them can cause a fatal hemolytic transfusion reaction. In this study, we report a case with the rare Bombay blood group that was misdiagnosed as the O blood group and developed a hemolytic transfusion reaction. This highlights the importance of both forward and reverse typing in ABO blood grouping and standard cross-matching and performing standard pretransfusion laboratory tests in hospital blood banks.

    Transfusion medicine training in Canada is currently undergoing a transformation from a time- and process-based curriculum to a competency-based medical education framework. Transfusion medicine is the first accredited postgraduate medical education training program in Canada to adopt a purely competency-based curriculum. It is serving as an example for a number of other postgraduate medical training programs undergoing a similar transition. The purpose of this review is to highlight the elements of competency-based medical education, describe its application to transfusion medicine training, and report on the development and implementation of the new transfusion medicine curriculum in Canada.

    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

    Full Text Available Background: Due to lack of correct blood grouping practices, the rare Bombay Oh phenotype may be missed, subjecting patients to the risk of severe hemolytic transfusion reaction. In the absence of blood donor registry, transfusion management of patients needing immediate surgery is a challenge. This study presents detection of rare Bombay Oh phenotype patients and their management by acute peri-operative acute normovolemic hemodilution (ANH in a hospital from central India. Materials and Methods: Blood grouping of patients and blood donors with a standard tube method was carried out and samples identified as rare Bombay phenotype were confirmed by saliva inhibition test. Surgical management of cases needing transfusion was done by ANH, as per the British Committee for Standards in Hematology guidelines. Results: The incidence of Bombay phenotype was 0.002% or 1 in 51,924 in the study. Amongst three cases (patients identified as Bombay phenotype, one was Bombay Oh, Rh negative. Two cases were missed in the first instance and one case actually did not require transfusion. In the absence of a blood donor registry for Bombay phenotype, the cases needing transfusion were successfully managed with ANH in the operation theatre. Conclusion: A simple test like blood grouping should be done with serious intention with incorporation of both forward and reverse grouping, so that no patient receives wrong blood leading to fatal hemolysis due to transfusion. ANH is a cost-effective transfusion option for suitable patients. Appropriate clinical decision making, use of strategies to decrease peri-operative blood losses and cost-effective country based planning could be more widely applied to improve clinical transfusion practice.

    Transfusion-transmitted cytomegalovirus (TT-CMV) is often asymptomatic, but certain patient populations, such as very low birth weight neonates, fetuses requiring intrauterine transfusion, pregnant women, patients with primary immunodeficiencies, transplant recipients, and patients receiving chemotherapy or transplantation for malignant disease, may be at risk of life-threatening CMV infection. It is unclear whether leukoreduction of cellular blood components is sufficient to reduce TT-CMV or whether CMV serological testing adds additional benefit to leukoreduction. The AABB CMV Prevention Work Group commissioned a systematic review to address these issues and subsequently develop clinical practice guidelines. However, the data were of poor quality, and no studies of significant size have been performed for over a decade. Rather than creating guidelines of questionable utility, the Work Group (with approval of the AABB Board of Directors) voted to prepare this Committee Report. There is wide variation in practices of using leukoreduced components alone or combining CMV-serology and leukoreduction to prevent TT-CMV for at-risk patients. Other approaches may also be feasible to prevent TT-CMV, including plasma nucleic acid testing, pathogen inactivation, and patient blood management programs to reduce the frequency of inappropriate transfusions. It is unlikely that future large-scale clinical trials will be performed to determine whether leukoreduction, CMV-serology, or a combination of both is superior. Consequently, alternative strategies including pragmatic randomized controlled trials, registries, and collaborations for electronic data merging, nontraditional approaches to inform evidence, or development of a systematic approach to inform expert opinion may help to address the issue of CMV-safe blood components.

    The main lesions of the skull and hand, observed in a group of hypertransfused β-thalassaemic patients, are compared with a control group of low-transfused patients. Bony abnormalities reflect the relationship between proliferating bone marrow and bone cortex, and hypertransfusion therapy will prevent development of lesions only if established early in life. If this is done, the diploe in the skull may become normal, overgrowth of facial bones is moderate, pneumatisation of the paranasal sinuses is not completely prevented, and the 'hair-brush' pattern may disappear completely. A normal appearance of the hand in adequately treated patients differentiates between prepubertal patients and adults. (orig.)

    2007-01-01

    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

  13. 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)

    2016-05-01

    Several clinical guidelines for the management of infants with severe neonatal hyperbilirubinemia recommend immediate exchange transfusion (ET) when the risk or presence of acute bilirubin encephalopathy is established in order to prevent chronic bilirubin encephalopathy or kernicterus. However, the literature is sparse concerning the interval between the time the decision for ET is made and the actual initiation of ET, especially in low- and middle-income countries (LMICs) with significant resource constraints but high rates of ET. This paper explores the various stages and potential delays during this interval in complying with the requirement for immediate ET for the affected infants, based on the available evidence from LMICs. The vital role of intensive phototherapy, efficient laboratory and logistical support, and clinical expertise for ET are highlighted. The challenges in securing informed parental consent, especially on religious grounds, and meeting the financial burden of this emergency procedure to facilitate timely ET are examined. Secondary delays arising from post-treatment bilirubin rebound with intensive phototherapy or ET are also discussed. These potential delays can compromise the effectiveness of ET and should provide additional impetus to curtail avoidable ET in LMICs. PMID:27170928

    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.

    ISO/IEC 18000-3 mode 1 standard 13.56 MHz RFID tags have been accepted by the International Society for Blood Transfusion (ISBT) and the United States Food and Drug Administration (FDA) as data carriers to integrate with and augment ISBT 128 barcode data carried on blood products. The use of 13.56 MHz RFID carrying ISBT 128 data structures allows the global deployment and use of RFID, supporting both international transfer of blood and international disaster relief. The deployment in process at the BloodCenter of Wisconsin and testing at the University of Iowa Health Center is the first FDA-permitted implementation of RFID throughout in all phases of blood banking, donation through transfusion. RFID technology and equipment selection will be discussed along with FDA-required RF safety testing; integration with the blood enterprise computing system and required RFID tag performance. Tag design and survivability is an issue due to blood bag centrifugation and irradiation. Deployment issues will be discussed. Use of RFID results in significant return on investment over the use of barcodes in the blood center operations through labor savings and error reduction.

  17. Role of the blood transfusion service in tissue banking.

    1996-01-01

    Tissue transplantation and banking are rapidly growing services throughout the world reflecting the widening availability of transplantable cadaver tissue and the mounting clinical indications particularly in orthopaedic, plastic and cardiovascular surgery. In the US tissue banking is more established, yet continues to show a rapid growth profile. In the UK it is currently organised in a variety of different ways and by a number of different organisations. The risks of disease transmission by tissue transplantation are similar to those for blood transfusion and the majority of tissues are grafted during procedures that are not life saving. The danger of disease transmission has resulted in the introduction of legislation in the US which allows the FDA to inspect tissue banks and to recall and destroy tissues. In the UK, there is currently no regulation or inspection of tissue banks to demonstrate that donor selection, tissue processing and tracking are conducted to acceptable standards. Blood transfusion services in the UK, US, New Zealand, Australia and possibly other countries have extended their roles to include organ and tissue donation to varying degrees, with the collection, processing and distribution of bone and tendon allografts most commonly undertaken. They have readily available special capabilities and experience with an established infrastructure, compliant with Good Manufacturing Practice, placing them in an ideal position to provide this service safely and cost-effectively.

  18. C-reactive (CRP) protein in transfusion dependent thalassaemic patients

    International Nuclear Information System (INIS)

    In thalassaemic patients iron overload, secondary to blood transfusion, results toxic effects by producing reactive radicals. Iron overload can be studied using serum ferritin level which has a direct correlation with the body's iron status. While oxidative damage can be studied using biomarker of inflammation like hsC-reactive proteins. Blood samples of 55 thalassaemic patients (39 males, 16 females) were collected from Fatmid Foundation (Hyderabad). The samples were analyzed for CBC, serum ferritin level and hsC-reactive proteins. High mean serum ferritin levels was found in all the patients regardless of the frequency of blood transfusion (4774.2135+-3143.3040 mu g/L), indicating the iron overload. High mean hsC-reactive protein was found (2.5151+-1.3712) with a positive correlation with ferritin (r= 0.8371198, p= 0.0000) and platelets (r= 0.43293443, p=0.000962175). C-reactive proteins serve as biomarker of various inflammatory conditions, progression of cardiovascular diseases and as indicator of morbidity and mortality. High C-reactive proteins in these patients indicate ongoing iron overload toxicity related damage in these patients. The estimation of hsC-reactive proteins and other biomarkers of inflammation and oxidation may help in better management of these patients. (author)

    Twin-twin transfusion syndrome (TTTS) is a severe complication of monozygotic (identical) twin fetuses sharing one single (monochorionic) placenta. TTTS is caused by a net inter-twin transfusion of blood through placental anastomoses, from one twin (the donor) to the other (the recipient), which link the two feto-placental circulations. Currently, the only reliable method to measure the net inter-twin transfusion clinically is when incomplete laser therapy of TTTS occurs and one of the twins becomes anemic and requires an intra-uterine transfusion of adult red blood cells. Then, differences between adult hemoglobin concentrations measured during the transfusion and at birth relate not only to the net inter-twin transfusion but also to the finite lifetime of the adult red blood cells. We have analyzed this situation, derived the differential equations of adult hemoglobin in the donor and recipient twins, given the solutions and given expressions relating the net inter-twin flow with clinically measured parameters. We have included single and multiple intra-uterine transfusions. In conclusion, because incomplete laser therapy occurs frequently, and some cases require an intra-uterine transfusion, this method may allow collecting a wealth of net inter-twin flow data from clinicians involved in laser therapy of TTTS. To aid to the widespread use of this method, we have presented the equations as clearly as possible in tables for easy use by others. (note)

    Background and objectives Blood transfusion is a lifesaving therapy for patients with hemoglobinopathies. However, the need of frequent transfusion carries the risk of transmitting hepatitis B and C infections which are intermediately prevalent in Syria. Despite screening blood donations with sensitive methods, the risk of transmission is still present when infectious blood is donated within the window period. This study aimed to investigate the incidence of HBV and HCV seropositivity, and its association with multiple transfusions among Syrian hemoglobinopathies patients. Materials and Methods HBsAg, anti-HBc, anti-HBs and anti-HCV were tested for 159 Syrian multi-transfused patients by Enzyme-Linked Immunosorbent Assay (ELISA). Results Thirty-nine of 159 (24.5%) multi-transfused patients were HBsAg/anti-HBc or anti-HCV positive, 26 (16%) of which never visited the dentist, and they either tested postsurgically negative for HBsAg and anti-HCV or never underwent a surgical procedure. On the contrary of anti-HCV seropositivity, HBsAg/anti-HBc seropositivity was significantly associated with the number of blood transfusions, number of blood units and age (P < 0.001). Conclusion About one-sixth of our patients most likely acquired HBV/HCV infection via blood transfusion. Administering HBV vaccine, ensuring the immune status, and monitoring hepatitis markers might considerably minimize the incidence of viral hepatitis among multi-transfused patients. PMID:27648209

    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.

    International Nuclear Information System (INIS)

    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 sequestrated int this organ, (b) splenic radioactive uptake increases with its post-transfusion reductin in size. (author)

    Introduction Dengue affects more than 50 million people per year and is one of the most common causes of severe thrombocytopaenia. Thrombocytopaenia is a common complication of dengue and other viral fevers apart from malaria, typhoid, leptospirosis, leukaemia and megaloblastic anaemia. A platelet count of homeopathic therapy, recipients of packed red cells on the same day of platelet transfusion and recipients of multiple platelet transfusions within 24 hours were excluded from the study. Results The median post transfusion platelet increments (PPI) and corrected count increments (CCI) at 4hour post transfusion were 25,000/μL (5,000-80,000/μL) and 18,000/μL (range 8,000/μL- 47,500/μL) respectively among the responders. Median PPI and CCI at 24 hours were 45,000/μL and 28,863/μL among the responders. The median CCI at 4 hour post transfusion among the non-responders was 850/μL and at 24hours was 1,425/μL. At 24 hours responders showed significantly higher PPI as compared to non responders. The average platelets transfused were 4units in case of responders and 8 units in case of non-responders. Conclusion ABO identical and compatible pooled platelet transfusions were more successful in increasing the post transfusion platelet counts as compared to ABO incompatible pooled platelets.

  7. Arterio-venous flow between monochorionic twins determined during intra-uterine transfusion

    International Nuclear Information System (INIS)

    Twin-twin transfusion syndrome (TTTS) is a severe complication of monozygotic (identical) twin fetuses sharing one single (monochorionic) placenta. TTTS is caused by a net inter-twin transfusion of blood through placental anastomoses, from one twin (the donor) to the other (the recipient), which link the two feto-placental circulations. Currently, the only reliable method to measure the net inter-twin transfusion clinically is when incomplete laser therapy of TTTS occurs and one of the twins becomes anemic and requires an intra-uterine transfusion of adult red blood cells. Then, differences between adult hemoglobin concentrations measured during the transfusion and at birth relate not only to the net inter-twin transfusion but also to the finite lifetime of the adult red blood cells. We have analyzed this situation, derived the differential equations of adult hemoglobin in the donor and recipient twins, given the solutions and given expressions relating the net inter-twin flow with clinically measured parameters. We have included single and multiple intra-uterine transfusions. In conclusion, because incomplete laser therapy occurs frequently, and some cases require an intra-uterine transfusion, this method may allow collecting a wealth of net inter-twin flow data from clinicians involved in laser therapy of TTTS. To aid to the widespread use of this method, we have presented the equations as clearly as possible in tables for easy use by others. (note)

    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

    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.

    The reported frequency of D alloimmunization in D- recipients after transfusion of D+ platelets varies. This study was designed to determine the frequency of D alloimmunization, previously reported to be an average of 5 ± 2%. A primary anti-D immune response was defined as the detection of anti-D ≥ 28 d following the first D+ platelet transfusion. Data were collected on 485 D- recipients of D+ platelets in 11 centres between 2010 and 2012. Their median age was 60 (range 2-100) years. Diagnoses included: haematological (203/485, 42%), oncological (64/485, 13%) and other diseases (218/485, 45%). Only 7/485 (1·44%; 95% CI 0·58-2·97%) recipients had a primary anti-D response after a median serological follow-up of 77 d (range: 28-2111). There were no statistically significant differences between the primary anti-D formers and the other patients, in terms of gender, age, receipt of immunosuppressive therapy, proportion of patients with haematological/oncological diseases, transfusion of whole blood-derived or apheresis platelets or both, and total number of transfused platelet products. This is the largest study with the longest follow-up of D alloimmunization following D+ platelet transfusion. The low frequency of D alloimmunization should be considered when deciding whether to administer Rh Immune Globulin to D- males and D- females without childbearing potential after transfusion of D+ platelets.

    Twin-twin transfusion syndrome (TTTS) is a severe complication of monozygotic (identical) twins, which share one single monochorionic placenta. It is caused by placental anastomoses which link the two fetoplacental circulations of the twins and allow a chronic net inter-twin transfusion to develop between the fetuses. Clinical presentation of TTTS manifestations has been classified into five different stages. In this paper, we used our computational model of TTTS and examined the possible differences between chronic and rapidly increasing inter-twin transfusion in the simulated TTTS staging sequence. Our results suggest that rapid alterations in the net inter-twin transfusion, e.g. due to thrombosis of placental anastomoses, may produce a different staging sequence than in TTTS caused by chronic inter-twin transfusion. These results may aid an improved knowledge of TTTS pathophysiology under conditions of a rapidly changing cardiovascular function, and contribute to the planning of optimal intervention under such circumstances.

    1999-07-01

    Full Text Available Blood transfusion therapy is often under-utilised in feline practice in South Africa. However, it is a technique that can be safely and effectively introduced in practice. Cats have naturally occurring allo-antibodies against the blood type that they lack, which makes blood typing, or alternatively cross-matching, essential before transfusions. Feline blood donors must be carefully selected, be disease free and should be sedated before blood collection. The preferred anticoagulant for feline blood collection is citrate-phosphatedextrose-adenine. Blood can either be administered intravenously or into the medullary cavity, with the transfusion rate depending on the cat's hydration status and cardiac function. Transfusion reactions can be immediate or delayed and they are classified as immunological or non-immunological. Indications, methods and techniques to do feline blood transfusions in a safe and economical way are highlighted.

    Summary Background This paper describes the transmission of hepatitis A virus (HAV) to two blood recipients from a healthy donor that later presented to the blood bank with jaundice. Methods The RNA of HAV was detected by qualitative nested reverse transcription polymerase chain reaction (nested RT-PCR) and quantified by real-time RT-PCR. HAV RNA samples were genotyped by direct sequencing of PCR products. A sequence from a fragment of 168 bp from the VP1/2A HAV region was used to construct a phylogenetic tree. Case Report A 31-year-old male donor accepted for donation of a whole blood unit returned to the blood bank with clinical jaundice 20 days after donation. His serological and NAT tests were negative for HBV and HCV. Serological tests for HAV IgM and IgG were negative on donation sample but positive on follow-up sample, confirming donor's HAV acute infection. Both recipients of red blood cells (R1) and platelet concentrate (R2) from the same implicated donation were HAV IgM-negative and IgG-positive. Qualitative PCR was positive on samples from all three individuals and phylogenetic analysis of viruses proved HAV transmission to the two recipients of blood products. HAV viral load on donor follow-up sample and the platelet recipient was 1.3 and 1.5 × 103 IU/ml, respectively. The RBC recipient, also infected by HCV, was undergoing bone marrow transplantation and died from fulminant hepatitis, 26 days after the implicated HAV transfusion. Conclusion The blood donor, a garbage collector, spontaneously returned to the blood bank when developing jaundice. This highlights the importance of donor education to immediately report to blood banks of any signs and symptoms related to infectious disease developed after blood donation. The fact that one immunocompromised patient with HCV infection died from fulminant hepatitis after receiving a HAV-contaminated platelet transfusion underpins the importance of a HAV vaccination program for these group of patients.

    Full Text Available Background. Various studies have raised concern of worse outcomes in patients receiving blood transfusions perioperatively compared to those who do not. In this study we attempted to determine the proportion of perioperative complications in the orthopedic population attributable to the use of a blood transfusion. Methods. Data from 400 hospitals in the United States were used to identify patients undergoing total hip or knee arthroplasty (THA and TKA from 2006 to 2010. Patient and health care demographics, as well as comorbidities and perioperative outcomes were compared. Multivariable logistic regression models were fitted to determine associations between transfusion, age, and comorbidities and various perioperative outcomes. Population attributable fraction (PAF was determined to measure the proportion of outcome attributable to transfusion and other risk factors. Results. Of 530,089 patients, 18.93% received a blood transfusion during their hospitalization. Patients requiring blood transfusion were significantly older and showed a higher comorbidity burden. In addition, these patients had significantly higher rates of major complications and a longer length of hospitalization. The logistic regression models showed that transfused patients were more likely to have adverse health outcomes than nontransfused patients. However, patients who were older or had preexisting diseases carried a higher risk than use of a transfusion for these outcomes. The need for a blood transfusion explained 9.51% (95% CI 9.12–9.90 of all major complications. Conclusions. Advanced age and high comorbidity may be responsible for a higher proportion of adverse outcomes in THA and TKA patients than blood transfusions.

    Introduction: The hospital blood bank (HBB) need to timely provide adequate amounts of blood and blood products for surgeries. For various surgical programs are performed assessments of the average number of blood doses needed for surgery. By using two types of requisitions BT/AB (blood type/antibody) and BT/AB/MT (blood type/antibody/match test) for pretransfusion immunohaematological testing in General Hospital “Prim. Dr. Abdulah Nakas” is achieved more rational consumption of blood and blood derivatives and financial savings through reduced number of matching tests (MT). Goal: To determine the total amount of pre-operative requisitions (BT/AB and BT/AB/MT) for blood and blood products at surgical departments of the General Hospital “Prim. Dr. Abdulah Nakas” in the period from June 1, 2014 – December 31, 2014 and analyze the consumption/return of blood in reserve in relation to the surgical disciplines, the total number of savings in MT. Conduct assessments MSBOS (Maximum Surgical Blood Ordering Schedule). Results: The total amount of preoperative requisitions for blood and blood products in surgical wards was 927 requests from which 623 demands or 67.2% is tested by BT/MT, while 304 or 32.8% was tested by BT/AB/MT. Transfused in total was 617 units of blood and blood products, 275 units were not transfused. Probability of transfusions for surgery was 51.3, the highest in the case of surgical intensive care 70.4 and the lowest for the department of general surgery 37.2%. Assessment of indicators of efficient resource management indicates they are the best at the delivery ward 0.89, while a total for surgical wards is 0.69. In total for surgery on the average were required 2.1 units of blood. By using two types of requisitions for pretransfusion immunohaematological testing (BT/AB and CG/AB/MT) is achieved more rational use of MT. In 623 requests for BT/AB only 61 MT were performed. Average of blood units issued in accordance with these requirements is 0

    Full Text Available Jose Mauro Kutner,1 Mariza Mota,1 Fabiana Conti,1 Lilian Castilho1,2 1Hemotherapy and Cell Therapy Department, Hospital Israelita Albert Einstein, São Paulo, SP, Brazil; 2Hemocentro Unicamp, Campinas, SP, Brazil Abstract: Blood transfusions are life sustaining in chronically transfused patients. 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.

    Introduction. Transfusion Transmitted Infections (TTIs) continue to be a major risk in transfusions in many parts of the world. The transfusion-dependent β-thalassaemia patients are particularly at risk of acquiring TTIs. The current study was undertaken to estimate the prevalence of TTIs in transfusion-dependent β-thalassaemia patients. Material and Methods. A cross-sectional study of 1253 multitransfused thalassaemia major patients was conducted in five different centres of Islamabad, Rawalpindi, and Karachi. The study subjects were screened for HIV, HCV, and HBV. The screening was performed at two centres: Department of Pathology, Shaheed Zulfiqar Ali Bhutto (SZAB) Medical University, and Blood Transfusion Services, Jinnah Postgraduate Medical Centre, from July to December 2015. The confirmatory screening was performed by Chemiluminescent Immunoassay (CLIA). Results. Out of the 1253 multiple transfused patients, 317 (25.3%) were infected with TTIs. HCV was positive in 273 cases (21.7%), HBV in 38 cases (3.0%), and HIV in 6 cases (0.5%). Conclusion. HCV was the leading TTI in multitransfused thalassaemia major patients in the study. Presence of HIV in thalassaemia patients is a recent disturbing development in Pakistan. Improved regulation of blood banks including use of internationally or nationally evaluated kits will bring down the incidence of TTIs in transfusion-dependent β-thalassaemia patients. More stringent behavioral and serological pretransfusion screening of blood for TTIs must be implemented in blood banks. PMID:27559490

    There is concern at the National Heart, Lung, and Blood Institute (NHLBI) and among transfusion medicine specialists regarding the small number of investigators and studies in the field of pediatric transfusion medicine (PTM). Accordingly, the objective of this article is to provide a snapshot of the clinical and translational PTM research considered to be of high priority by pediatricians, neonatologists, and transfusion medicine specialists. Included is a targeted review of three research areas of importance: (i) transfusion strategies, (ii) short- and long-term clinical consequences, and (iii) transfusion-transmitted infectious diseases. The recommendations by PTM and transfusion medicine specialists represent opportunities and innovative strategies to execute translational research, observational studies, and clinical trials of high relevance to PTM. With the explosion of new biomedical knowledge and increasingly sophisticated methodologies over the past decade, this is an exciting time to consider transfusion medicine as a paradigm for addressing questions related to fields such as cell biology, immunology, neurodevelopment, outcomes research, and many others. Increased awareness of PTM as an important, fertile field and the promotion of accompanying opportunities will help establish PTM as a viable career option and advance basic and clinical investigation to improve the health and wellbeing of children.

    Transfusion support is a key enabler to the response to mass casualty events (MCEs). Transfusion demand and capability planning should be an integrated part of the medical planning process for emergency system preparedness. Historical reviews have recently supported demand planning for MCEs and mass gatherings; however, computer modeling offers greater insights for resource management. The challenge remains balancing demand and supply especially the demand for universal components such as group O red blood cells. The current prehospital and hospital capability has benefited from investment in the management of massive hemorrhage. The management of massive hemorrhage should address both hemorrhage control and hemostatic support. Labile blood components cannot be stockpiled and a large surge in demand is a challenge for transfusion providers. The use of blood components may need to be triaged and demand managed. Two contrasting models of transfusion planning for MCEs are described. Both illustrate an integrated approach to preparedness where blood transfusion services work closely with health care providers and the donor community. Preparedness includes appropriate stock management and resupply from other centers. However, the introduction of alternative transfusion products, transfusion triage, and the greater use of an emergency donor panel to provide whole blood may permit greater resilience.

    Full Text Available Introduction: The appropriate use of blood and blood products means the transfusion of safe blood products only to treat a condition leading to significant morbidity or mortality, which cannot be prevented or managed effectively by other means. The safety and effectiveness of transfusion depend on the appropriate clinical use of blood and blood products. This study was conducted to review the practice of fresh frozen plasma usage (FFP for transfusion, based on the coagulation profile, requested by various departments in the Hospital Universiti Sains Malaysia (HUSM. Methodology: A retrospective review of blood bank records and coagulation profile results of the patients given FFP from October to December 2006, in Hospital USM was undertaken. The criteria set by the College of American Pathologists in 1994, were used as the guidelines. Results: One thousand six hundred and ninety-eight units of FFP were used during this study period. Only 806 (47.47% FFP units were deemed appropriate. 20.38% were based on studies without any coagulation tests prior to transfusion and 21.13% were transfused for mild prolongation of coagulation test results. About 6.41% requested FFP in the setting of normal coagulation results. Conclusion: Our results showed that a significant proportion of the FFP transfusion was not guided by the coagulation profile. We recommend that a continuous education on FFP transfusion may help to guide the appropriate request for FFP.

    The ability of the calcium antagonists, cinnarizine and flunarizine, to enhance the radiosensitisation produced by the administration of an erythrocyte transfusion to anaemic, RIF-1 or SCCVII/St tumour bearing mice was determined. Erythrocyte transfusion alone increased radiation cell killing 10-fold in the RIF-1 tumour when given 0-4 h before X-rays. In contrast, the SCCVII/St showed only a 4-fold increase in sensitivity, apparent when erythrocytes were given 2-6 h before irradiation. The administration of 50 mg kg-1 cinnarizine or flunarizine to anaemic mice followed by erythrocyte transfusion 0 h before X-rays produced the same level of cell survival for both tumours, a 20-fold increase in cell killing for cinnarizine, and a 30-40-fold effect for flunarizine, even though at this time interval, the erythrocyte transfusion alone did not sensitise the SCCVII/St tumour to X-rays. Further investigations indicated, however, that the erythrocyte transfusion was necessary to achieve the sensitisation with the calcium antagonists, since giving flunarizine to anaemic mice alone only achieved a 4-fold increase in radiation cell killing. In addition, flunarizine given with erythrocyte transfusion 4 h before X-rays, in SCCVII/St, the optimal time for radiosensitisation in this tumour, did not further increase the level of cell killing achieved by flunarizine plus erythrocyte transfusion 0 h before X-rays.

    Full Text Available Background: The development of anti-red blood cell antibodies (both allo-and autoantibodies remains a major problem in thalassemia major patients. We studied the frequency of red blood cell (RBC alloimmunization and autoimmunization among thalassemia patients who received regular transfusions at our center and analyzed the factors, which may be responsible for development of these antibodies. Materials and Methods: The study was carried out on 319 multiply transfused patients with β-thalassemia major registered with thalassemia clinic at our institute. Clinical and transfusion records of all the patients were examined for age of patients, age at initiation of transfusion therapy, total number of blood units transfused, transfusion interval, status of splenectomy or other interventions. Alloantibody screening and identification was done using three cell and 11 cell panel (Diapanel, Bio-rad, Switzerland respectively. To detect autoantibodies, autocontrol was carried out using polyspecific coombs (IgG + C3d gel cards. Results: Eighteen patients out of total 319 patients (5.64% developed alloantibodies and 90 (28.2% developed autoantibodies. Nine out of 18 patients with alloantibodies also had autoantibodies. Age at first transfusion was significantly higher in alloimmunized than non-immunized patients (P = 0.042. Out of 23 alloantibodies, 52.17% belonged to Rh blood group system (Anti-E = 17%, Anti D = 13%, Anti-C = 13%, Anti-C w = 9%, 35% belonged to Kell blood group system, 9% of Kidd and 4% of Xg blood group system. Conclusion: Alloimmunization was detected in 5.64% of multitransfused thalassemia patients. Rh and Kell blood group system antibodies accounted for more than 80% of alloantibodies. This study re-emphasizes the need for RBC antigen typing before first transfusion and issue of antigen matched blood (at least for Rh and Kell antigen. Early institution of transfusion therapy after diagnosis is another means of decreasing

    Full Text Available Abstract Background Anemic syndrome is a frequent problem in intensive care units. The most probable etiology is the suppression of the erythropoietin response due to the direct effects of cytokines, as well as frequent blood sampling. Transfusions are not free of complications, therefore transfusion reactions are estimated to occur in 2% of the total packed red blood cells (pRBCs transfused. In the past several years, several trials had tried to compare the restrictive with the more liberal use of transfusions, and they were found to be equally effective. Nosocomial pneumonia is the most common nosocomial infection in intensive care units; the prevalence is 47% with an attributive mortality of 33%. There are multiple risk factors for the development of nosocomial pneumonia. Colonization of the upper airways is the most important pathophysiological factor but there are other factors implicated like, sedation techniques, inappropriate use of antibiotics and recumbent positioning. A secondary analysis of the CRIT study describes transfusion therapy and its practices in the United States. They found that transfusion practice is an independent risk factor for the development of nosocomial pneumonia. Methods This is a multicenter, prospective cohort study in different intensive care units in Colombia. A total of 474 patients were selected who had more than 48 hours of mechanical ventilation. The primary objective is to try to demonstrate the hypothetical relationship between the use of transfusions and nosocomial pneumonia. Secondly, we will try to determine which other factors are implicated in the development of pneumonia in intensive care units and describe the incidence of pneumonia and transfusion practices. Discussion Ventilator associated pneumonia is a primary problem in the intensive care unit, multiple factors have been associated with its presence in this study we try to explore the possible association between pneumonia and transfusion

    Full Text Available Purpose: There are multiple reported risk factors and a wide range of reported blood transfusion rates for total shoulder arthroplasty (TSA. 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. Level of Evidence: Level II, retrospective cohort study, prognostic study.

  19. 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.

    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.

  1. 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 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

    2011-12-01

    Dengue fever (DF) has several hematological manifestations including thrombocytopenia and increased bleeding risk. Prophylactic platelet transfusion-in the absence of major bleeding-is utilized in DF with thrombocytopenia with the intention of preventing hemorrhagic complications. However, prophylactic platelet transfusion in DF is neither standardized nor supported by clinical evidence. We conclude that risks, costs and poor resource utilization associated with prophylactic platelet transfusion in DF far outweigh any potential hematological benefit, and as such, should not constitute routine clinical practice.

    We report a case series of acute arsenic poisoning of 2 siblings, a 4-month-old male infant and his 2-year-old sister. Each child ingested solubilized inorganic arsenic from an outdated pesticide that was misidentified as spring water. The 4-month-old child ingested a dose of arsenic that was lethal despite extraordinary attempts at arsenic removal, including chelation therapy, extracorporeal membrane oxygenation, exchange transfusion, and hemodialysis. The 2-year-old fared well with conventional therapy. PMID:15995066

    Directory of Open Access Journals (Sweden)

    Xi Zhang

    Full Text Available BACKGROUND: Factors affecting the efficacy of platelet and red blood cell (RBC transfusion in patients undergoing hematopoietic stem cell transplantation (HSCT have not been studied extensively. We aimed to evaluate platelet and RBC transfusion efficacy by measuring the platelet corrected count increment and the hemoglobin increment, respectively, 24 h after transfusion in 105 patients who received HSCT. METHODOLOGY/PRINCIPAL FINDINGS: Using retrospective analysis, we studied whether factors, including gender, time of transplantation, the compatibility of ABO group between HSC donors and recipients, and autologous or allogenic transplantation, influence the efficacy of blood component transfusion. We found that the infection rate of HSCT patients positively correlated with the transfusion amount, and the length of stay in the laminar flow room was associated with transfusion. We found that platelet transfusion performed during HSCT showed significantly better efficacy than that performed before HSCT. The effect of platelet transfusion in auto-transplantation was significantly better than that in allo-transplantation. The efficacy of RBC transfusion during HSCT was significantly lower than that performed before HSCT. The efficacy of RBC transfusion in auto-transplantation was significantly higher than that in allo-transplantation. Allo-transplantation patients who received HSCs from compatible ABO groups showed significantly higher efficacy during both platelet and RBC transfusion. CONCLUSIONS: We conclude that the efficacy of platelet and RBC transfusions does not correlate with the gender of patients, while it significantly correlates with the time of transplantation, type of transplantation, and ABO compatibility between HSC donors and recipients. During HSCT, the infection rate of patients positively correlates with the transfusion amount of RBCs and platelets. The total volume of RBC units transfused positively correlates with the length of

  7. Ethico-legal aspects of hospital-based blood transfusion practice; implications of professional negligence to medical practitioners: a review

    Orkuma J.A

    2014-12-01

    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.

    Admission red cell distribution width (aRDW) has been shown to predict mortality in trauma patients by an unclear mechanism. It has been speculated that aRDW is a marker of chronic health status, but elevated RDW may also reflect recent hemorrhage. We hypothesized that aRDW is a predictor of major hemorrhage in trauma patients. Shock trauma patients at a Level I trauma center over 6.5 years were evaluated. Patients were stratified by aRDW quintile (Q1: less than 13%, Q2: 13.1 to 13.5%, Q3: 13.6 to 14.0%, Q4: 14.1 to 14.9%, Q5: 15.0% or greater). Massive transfusion (MT) was defined as 10 or more packed red blood cells in the first 24 hours. From multiple logistic regression, odds ratios with 95 per cent confidence intervals (CIs) were determined to evaluate the association between aRDW quintile and MT. Three thousand nine hundred ninety-four met study criteria. Overall MT incidence was 10 per cent and in-hospital mortality was 17 per cent. MT and mortality increased in a stepwise fashion by aRDW quintile (P < 0.0001). From logistic regression, a threefold increased odds of MT was associated with aRDW Q4 (CI, 1.81 to 4.92), and a 3.5-fold increased odds of MT was associated with aRDW Q5 (CI, 2.70 to 5.83). aRDW independently predicted MT, suggesting that elevated aRDW is an indicator of major hemorrhage in trauma patients. The association between aRDW and mortality in trauma patients may be explained by acute hemorrhage rather than chronic health status.

    The objectives of this study were to evaluate the cost-effectiveness and budget impact of octaplasLG(®) compared with fresh-frozen plasma (FFP) in all patients receiving a transfusion in Canada. A decision analytic framework was used to model acute and long-term complications that could follow plasma transfusion. Over a life time horizon, the cost with octaplasLG(®) were CA$612.91, which is CA$303.14 less than those with FFP. OctaplasLG(®) resulted in 0.021 quality adjusted life years (QALYs) gained in comparison with FFP. Because of higher efficacy and lower costs, octaplasLG(®) is expected to be the dominant treatment option over FFP in Canada.

    Magnetic resonance (MR) marrow signal in the axial and appendicular skeleton of 13 transfusion-dependent and chelated pediatric patients with sickle cell anemia (SSD) was compared with marrow signal in six non-transfusion-dependent patients with SSD. Hepatic, pancreatic, and renal MR signal were also evaluated. Indication for hypertransfusion therapy was primarily prior history of stroke. Transfusion-dependent patients had evidence of iron deposition throughout the imaged marrow and the liver, despite deferoxamine chelation therapy. Non-transfusion-dependent patients did not demonstrate grossly apparent signs of iron overload. Red marrow restoration was present in the spine, pelvis, and long bones and, in some patients, within the epiphyses. Marrow edema secondary to vaso-occlusive crises was evident in the metaphyses and diaphyses of long bones in areas of both red and fatty marrow and was best seen using fat-saturated T2-weighted imaging techniques.

    2006-01-01

    Blood transfusion is developing rapidly in the European Union. Though a compromise between technocrats, lobbies and blood transfusion professionals, the new specific EU directive (2002/98/EC) was a major step forward. In the future, blood transfusion in the EU must be centered on medical, scientific and social criteria, within a sound ethical and non commercial framework. Attention must be paid to the needs of patients and blood donors alike. The EuroNet-TMS survey is highly informative in this respect. National transfusion systems are extremely heterogeneous, ranging from public services to profit-oriented organizations. The approach to donors varies from one country and culture to another Some member states prescribe 2.5 times more blood products than others. Likewise, prevention and haemovigilance strategies are highly variable, with no attempt at harmonization.

    Clarifying the existing evidence base is crucial to improve the effectiveness of transfusion practice. The UK Systematic Review Initiative has been pursuing this objective primarily through writing systematic reviews on important topics in transfusion medicine. Here, we describe our progress for the past 5 years. We are the only research group that identifies transfusion medicine randomized controlled trials (RCTs) for the Cochrane Central Register of Controlled Trials, and to date, we have contributed 3002 RCT citations. The article considers future challenges including the need for wider involvement from the transfusion medicine community in the process of maintaining and updating systematic reviews and the identification and prioritization of topics for further clinical research including clinical trials. Collaboration between international and local research groups is important if these challenges are to be met. PMID:19320853

    We have investigated the effect of using tranexamic acid (TXA) during peri-acetabular osteotomy (PAO) on peri-operative blood loss and blood transfusion requirements. In addition we analysed whether the use of TXA was associated with an increased risk of venous thromboembolism (VTE) following this procedure. A consecutive series of 96 PAOs, performed by a single surgeon, were reviewed. A total of 48 patients received TXA and 48 did not. The TXA group received a continuous infusion of TXA at a rate of 10 mg/kg/h. The primary outcome measure was the requirement for blood transfusion. Secondary outcomes included total blood loss, the decrease in the level of haemoglobin in the blood, the length of hospital stay, and the complications of this treatment. The mean rate of transfusion was significantly lower in the TXA group (62.5% vs 12.5%, p transfusion after PAO significantly, without adverse effects such as an increased rate of VTE.

    Intermediate beta-thalassemia has a broad spectrum of sequelae and affected subjects may require occasional blood transfusions over their lifetime to correct anemia. Iron overload in intermediate beta-thalassemia results from a paradoxical intestinal absorption, iron release from macrophages and hepatocytes, and sporadic transfusions. Pathological iron accumulation in parenchyma is caused by chronic exposure to non-transferrin bound iron in plasma. The iron scavenger and transport protein transferrin is a potential treatment being studied for correction of anemia. However, transferrin may also function to prevent or reduce iron loading of tissues when exposure to non-transferrin bound iron increases. Here we evaluate the effects of apotransferrin administration on tissue iron loading and early tissue pathology in non-transfused and transfused Hbb(th3/+) mice. Mice with the Hbb(th3/+) phenotype have mild to moderate anemia and consistent tissue iron accumulation in the spleen, liver, kidneys and myocardium. Chronic apotransferrin administration resulted in normalization of the anemia. Furthermore, it normalized tissue iron content in the liver, kidney and heart and attenuated early tissue changes in non-transfused Hbb(th3/+) mice. Apotransferrin treatment was also found to attenuate transfusion-mediated increases in plasma non-transferrin bound iron and associated excess tissue iron loading. These therapeutic effects were associated with normalization of transferrin saturation and suppressed plasma non-transferrin bound iron. Apotransferrin treatment modulated a fundamental iron regulatory pathway, as evidenced by decreased erythroid Fam132b gene (erythroferrone) expression, increased liver hepcidin gene expression and plasma hepcidin-25 levels and consequently reduced intestinal ferroportin-1 in apotransferrin-treated thalassemic mice.

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

    We assessed regional differences in potentially discretionary [coronary artery bypass (CABG) surgery. Regional variation in overall RBC rates remained after risk adjustment, perhaps due to differences in regional practice environments. Objective A number of established regional quality improvement collaboratives have partnered to assess and improve care across their regions under the umbrella of the “Cardiac Surgery Quality IMPROVEment (IMPROVE) Network”. The first effort of the IMPROVE Network has been to assess regional differences in potentially discretionary [coronary artery bypass (CABG) surgery across 56 medical centers in four IMPROVE Network regions between January 2008 and June 2012. Each center submitted the most recent 200 patients who received 0, 1, or 2 units of RBC transfusion during the index admission. Patient and disease characteristics, intra-operative practices, and percentage of cases receiving RBC transfusions were collected. Region-specific transfusion rates were calculated, after adjusting for pre- and intra-operative factors among region-specific centers. Results There were small, but significant, differences in patient case mix across regions. RBC transfusions of 1 or 2 units occurred among 25.2% (2,826/11,200) of CABG procedures. Significant variation in use and number of RBCs existed across regions [None: 74.8% (min:max 70.0%, 84.1%), 1 unit: 9.7% (5.1%, 11.8%), 2 units: 15.5% (9.1%, 18.2%)], p<0.001. Variation in overall transfusion rates remained after adjustment (9.1% – 31.7%, p<0.001). Conclusions Delivery of small volumes of RBC transfusions was common, yet varied across geographic regions. These data suggest that differences in regional practice environments, including transfusion triggers and anemia management, may contribute to variability in RBC transfusion rates. PMID:25227699

  14. Improving decision making for massive transfusions in a resource poor setting: a preliminary study in Kenya.

    Directory of Open Access Journals (Sweden)

    Elisabeth D Riviello

    Full Text Available The reality of finite resources has a real-world impact on a patient's ability to receive life-saving care in resource-poor settings. Blood for transfusion is an example of a scarce resource. Very few studies have looked at predictors of survival in patients requiring massive transfusion. We used data from a rural hospital in Kenya to develop a prediction model of survival among patients receiving massive transfusion.Patients who received five or more units of whole blood within 48 hours between 2004 and 2010 were identified from a blood registry in a rural hospital in Kenya. Presenting characteristics and in-hospital survival were collected from charts. Using stepwise selection, a logistic model was developed to predict who would survive with massive transfusion versus those who would die despite transfusion. An ROC curve was created from this model to quantify its predictive power.Ninety-five patients with data available met inclusion criteria, and 74% survived to discharge. The number of units transfused was not a predictor of mortality, and no threshold for futility could be identified. Preliminary results suggest that initial blood pressure, lack of comorbidities, and indication for transfusion are the most important predictors of survival. The ROC curve derived from our model demonstrates an area under the curve (AUC equal to 0.757, with optimism of 0.023 based on a bootstrap validation.This study provides a framework for making prioritization decisions for the use of whole blood in the setting of massive bleeding. Our analysis demonstrated an overall survival rate for patients receiving massive transfusion that was higher than clinical perception. Our analysis also produced a preliminary model to predict survival in patients with massive bleeding. Prediction analyses can contribute to more efficient prioritization decisions; these decisions must also include other considerations such as equity, acceptability, affordability and

    This study was aimed to explore the correlation of hemogram changes during pregnancy of healthy women with postpartum blood transfusion. The outpatient and inpatient information of expectant lying-in women in our hospitals was collected, the route blood test, lever and kidney function and blood coagulation function tests were performed from the 4th to the 10th month of pregnancy. The pregnant women without underlying diseases and non-elderly pregnant women with single fetus were selected as the subjects of study. They were divided into postpartum blood transfusion group and non-blood transfusion group. The white blood cell (WBC) count, hemoglobin (Hb) level, platelet (Plt) count, plateletocrit (PCT), mean platelet volume (MPV), platelet distribution width (PDW) were compared in 2 groups. The results showed that 68 cases out of 450 expectant lying-in women received blood transfusion, among them 30 cases with complete data of puerperal transfusion were taken as blood transfusion group, the 28 cases of non transfusion puerperal as control group. There was no significant difference of hemogram changes between the two groups. However, there was a slight decline in Plt count and Hb level of late pregnant women. What is more, there was no correlation between Plt count change and the PCT, MPV and PDW. It is concluded that the changes of hemogram during pregnancy has no correlation with postpartum hemorrhage and blood transfusion in healthy pregnant women, the Plt count and Hb level of pregnant women slightly decline. Nevertheless, PCT, MPV and PDW are within the normal range.

    Perioperative acute kidney injury (AKI) is not uncommon and is associated with considerable morbidity and mortality. Recently, several definition systems for AKI were proposed, incorporating both small changes of serum creatinine and urinary output reduction as diagnostic criteria. Novel biomarkers are under investigation as fast and accurate predictors of AKI. Several special considerations regarding the risk of AKI are of note in the surgical patient. Co-morbidities are important risk factors for AKI. The surgery in itself, especially emergency and major surgery in the critically ill, is associated with a high incidence of AKI. Certain types of surgeries, such as cardiac and transplantation surgeries, require special attention because they carry higher risk of AKI. Nephrotoxic drugs, contrast dye, and diuretics are commonly used in the perioperative period and are responsible for a significant amount of in-hospital AKI. Before surgery, the anaesthetist is required to identify patients at risk of AKI, optimize anaemia, and treat hypovolaemia. During surgery, normovolaemia is of utmost importance. Additionally, the surgical and anaesthesia team is advised to use measures to reduce blood loss and avoid unnecessary blood transfusion. Hypotension should be avoided because even short periods of mean arterial pressure patients. Urine output can be reduced significantly during surgery and is unrelated to perioperative renal function. Thus, fluids should not be given in excess for the sole purpose of avoiding or treating oliguria. Use of hydroxyethyl starch needs to be reconsidered. Recent evidence indicates a beneficial effect of administering low-chloride solutions. PMID:26658199

    Full Text Available This paper, based on relevant literature articles and the authors' clinical experience, presents a goal-oriented respiratory management for critically ill patients with acute respiratory distress syndrome (ARDS that can help improve clinicians' ability to care for these patients. Early recognition of ARDS modified risk factors and avoidance of aggravating factors during hospital stay such as nonprotective mechanical ventilation, multiple blood products transfusions, positive fluid balance, ventilator-associated pneumonia, and gastric aspiration can help decrease its incidence. An early extensive clinical, laboratory, and imaging evaluation of “at risk patients” allows a correct diagnosis of ARDS, assessment of comorbidities, and calculation of prognostic indices, so that a careful treatment can be planned. Rapid administration of antibiotics and resuscitative measures in case of sepsis and septic shock associated with protective ventilatory strategies and early short-term paralysis associated with differential ventilatory techniques (recruitment maneuvers with adequate positive end-expiratory pressure titration, prone position, and new extracorporeal membrane oxygenation techniques in severe ARDS can help improve its prognosis. Revaluation of ARDS patients on the third day of evolution (Sequential Organ Failure Assessment (SOFA, biomarkers and response to infection therapy allows changes in the initial treatment plans and can help decrease ARDS mortality.

    Full Text Available Background: Leukemia is the second most malignant tumor in children. The chemotherapy induced anemia(CIA and hemorrhage are the most popular side-effects due to the myelosuppression of chemotherapy. So far,multitransfusion is still the timely and effective measure in curing these complications. The acquisition of HIV infection and subsequent development of AIDS by component transfusion from donors at risk is well known,and prognosis of HIV infection is particularly severe in patients with leukemia.Case Presentation: We report two leukemic cases that were infected with HIV through transfusion. The first patient was totally transfused with 16 U RBC, 20 U platelets and 820 ml fresh frozen plasma, and later test showed that his first used FFP carried the HIV. For the second 2 U RBC, 5 U platelets and 1500 ml fresh frozenplasma were transfused to her. Late test of her used blood products showed that the fourth RBC carried the HIV. Both results were confirmed by the local Center for Disease Control (CDC. They were not transfused before the diagnosis of leukemia. Their parents were healthy with negative HIV-Ab Conclusion: Since the two leukemic patients suffered transfusion-associated HIV with poor prognosis, we must take more efforts to utilize blood products judiciously, manage blood donors, test blood samples etiologically, shorten HIV testing "window periods" and develop preventive vaccination against HIV to reduce the incidence as low as possible.

    The need for red cell transfusions is reduced but not eliminated by recombinant human erythropoietin (rhEPO) in very low birthweight (VLBW) infants. To detect factors associated with the decision to transfuse VLBW infants during rhEPO treatment and to explain rhEPO 'non-responders', the subgroup of those 120 VLBW infants who were treated with rhEPO 750 IU/kg per week in the second European Multicentre rhEPO Trial was evaluated. Sixty (50%) infants received at least one transfusion during erythropoietin treatment. Transfusion was frequent in infants with extremely low birthweight (79% for 750-999 g), low gestational age (70% for or = 1 ml/kg per day). The prognostic variables birthweight, initial haematocrit, and gestational age were found to be most predictive for transfusion. To improve rhEPO response in VLBW infants, there is a need to minimise diagnostic blood loss, to prevent iron deficiency, and to develop rational criteria for transfusion in preterm infants.

    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.

    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

    Full Text Available Background: Thalassemia is a collection of genetic impairments in beta and alpha genes causing various states of anemia. Severe types of the disease need lifelong transfusions, leading to oxidant-antioxidant disturbance due to massive iron deposits. Aims: The aim of this study was to assess the antioxidant enzyme Superoxide Dismutase (SOD and ferritin levels of thalassemia major patients in a peripheral health facility. Materials and Methods: Two hundred and nine probands were recruited and performed laboratory experiments for SOD and Ferritin levels. Chelation administration and clinical score were taken from interviewing the family and from medical report data. Results: The study showed that SOD intensity was lower (162.41 u/ml compared to the normal cutoff point (P = 0.001, while the mean of Ferritin levels was ten times over the normal value (4226,67 ng/dl. Observations also reported that chelation medicine was not administrated properly. Conclusions: The data indicates that thalassemic patients have oxidant-antioxidant uproar due to oxidative stress. Monitored chelating administration, selective antioxidant, and a well-balanced diet may prevent oxidative injury.

    Ultraviolet (UV)-B irradiation abolishes lymphocyte functions (the ability to respond and to stimulate) in mixed lymphocyte culture (MLC). This effect may have practical application in the prevention or reduction of transfusion-induced alloimmunization against HLA class I antigens. To study this, platelet concentrates (PCs) were obtained with a cell separator, suspended in autologous plasma in a final volume of 400 mL, and transferred into a large (22 X 30 cm) cell culture bag. This plastic showed a good transmittance of UV-B rays at 310 nm (54%). PCs were placed between two quartz plates (surface of irradiation = 25 X 37 cm), and the two sides were irradiated simultaneously. Energy delivered to the surface of the plastic bag was automatically monitored. The ability to respond (in MLC and to phytohemagglutinin) and to stimulate allogeneic lymphocytes was completely abolished with energy of 0.75 J per cm2 (irradiation time less than 3 min). The temperature increase during irradiation was negligible. Platelet aggregation (collagen, adrenalin, ADP, arachidonic acid, ristocetin) was not impaired if UV-B energy was below 3 J per cm2. Recovery and survival of autologous 111In-labeled platelets were studied in four volunteers; no differences were found between UV-B-treated (1.5 J/cm2) platelets and untreated platelets. These results show that a large-scale clinical trial using UV-B-irradiated PCs to prevent HLA alloimmunization is feasible.

    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

    One hundred and thirty-nine couples referred because of recurrent abortions with no obvious cause were assessed for genetic similarity using the HLA major histocompatibility system. Comparison with 103 fertile control couples demonstrated that a much higher proportion of couples in the abortion group shared two or more HLA antigens. Using this criterion, 44 wives out of the 139 couples referred, when compared with a child-bearing group, appeared to share a greater than expected number of histocompatibility antigens and were therefore considered suitable for treatment. Twenty-eight wives have received treatment with white cell infusions from erythrocyte-compatible donors and so far they have delivered 17 babies plus 2 second babies. Another 3 wives are pregnant beyond their previous dates for abortions (1 first and 2 second pregnancies). There have been 5 failures (4 first pregnancy and 1 second pregnancy); one of these was treated a second time and has now successfully delivered. Seven couples are awaiting conception. Of the patients who have become pregnant, 81.5% have had successful deliveries. No adverse transfusion reactions have been observed. PMID:4020795

    Routine assessment of body iron load in patients with acute leukemia is usually done by serum ferritin (SF) assay; however, its sensitivity is impaired by different conditions including inflammation and malignancy. To estimate, using MRI, the extent of liver iron overload in children with acute leukemia and receiving blood transfusions, and to examine the association between the degree of hepatic iron overload and clinical parameters including SF and the transfusion iron load (TIL). A total of 25 MRI measurements of the liver were performed in 15 children with acute leukemia (mean age 9.75 years) using gradient-echo sequences. Signal intensity ratios between the liver and the vertebral muscle (L/M ratio) were calculated and compared with SF-levels. TIL was estimated from the cumulative blood volume received, assuming an amount of 200 mg iron per transfused red blood cell unit. Statistical analysis revealed good correlation between the L/M SI ratio and TIL (r = -0.67, P = 0.002, 95% confidence interval CI = -0.83 to -0.34) in patients with acute leukemia as well as between L/M SI ratio and SF (r = -0.76, P = 0.0003, 95% CI = -0.89 to -0.52). SF may reliably reflect liver iron stores as a routine marker in patients suffering from acute leukemia. (orig.)

    Full Text Available Background: This study was designed to determine the prevalence and assess the risk factors responsible for platelet transfusion refractoriness in hemato-oncological patients. Materials and Methods: The study included 30 patients. Twelve were clinically diagnosed as aplastic anemia and the 18 were of acute myeloid leukemia. A prospective 3 months follow-up was planned to monitor the response of platelet transfusion therapy, based on their posttransfusion corrected count increment at 1 st and 24 th h. Based on the observations, patients were categorized into refractory and nonrefractory groups. Common nonimmunological causes such as fever, sepsis, bleeding, disseminated intravascular coagulation, chemotherapy, splenomegaly, ABO mismatch, and antithymocyte globulin therapy were monitored. Among the immunological causes, presence of antihuman leukocyte antigen (HLA class I antibodies and platelet glycoprotein antibodies in patient′s serum were monitored. Results: During the study period, 17 (56.66% patients did not show desired platelet count increment. Transfusion requirements of refractory group for both red cell and platelet product were significantly higher (P < 0.05 in comparison to nonrefractory group. Among immunological causes, anti HLA class I antibodies (P < 0.013, antihuman platelet antigen-5b antibodies (P < 0.033 were significantly associated with refractoriness. Among nonimmunological causes, bleeding (P < 0.019, odd ratio 8.7, fever (P < 0.08, odd ratio 5.2, and infection (P < 0.07, odd ratio 5.4 were found to associated with refractoriness. Conclusion: Platelet refractoriness should be suspected in multitransfused patients not showing expected increment in platelet counts and thoroughly investigated to frame further guidelines in order to ensure proper management of these kind of patients.

    The issue of the clinical appropriateness of blood transfusion has become a focus of transfusion medicine worldwide. In China, irrational uses of blood have often been reported in recent years. However, to date there lacks a systematic review of the rational uses of blood. This study aimed to determine the clinical appropriateness of blood transfusion in China. We searched PubMed, Web of Science, the Cochrane Library, China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database, WanFang Database, and Chinese BioMedical Literature Database, and the retrieval cut-off date was June 31, 2015. SPSS 17.0 and MetaAnalyst 3.13 were employed as the statistics tools in this review. A pooled rate of clinical inappropriateness of transfusion was analyzed by DerSimonian-Laird method. In this study, a total of 39 observational studies were included, which related to 75,132 cases of blood transfusion. According to the meta-analysis results, the overall incidence of clinical inappropriateness of transfusion in China was estimated to be 37.3% (95% confidence interval [CI] [32.1, 42.8]). The subgroup analyses revealed that the pooled rates of clinical inappropriateness of transfusion of plasma, red blood cells (RBCs), cryoprecipitate, and platelets were 56.3% (95% CI [45.8, 66.2]), 30.9% (95% CI [27.1, 35.0]), 25.2% (95% CI [13.2, 42.7]), and 14.1% (95% CI [8.8, 21.9]), respectively. However, the pooled incidence of inappropriateness of transfusion in operative departments was 47.5% (95% CI [36.8, 58.3]), which was significantly higher than that in nonoperative departments, 25.8% (95% CI [18.7, 34.4], P  0.05). In conclusion, China has suffered from a disadvantage in the clinical appropriateness of blood transfusion, especially in plasma and RBC use. In future, comprehensive measures should be implemented in order to improve the clinical appropriateness of blood transfusion.

    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

    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

    Full Text Available Acute panmyelosis with myelofibrosis (APMF is a rare, fatal hematological neoplasm that is characterized by the acute onset of cytopenias and fibrosis in the bone marrow in the absence of splenomegaly or fibrosis-related morphological changes in the RBCs. We present the case of a 59-year-old female who presented with a two-month history of anemia, leucopenia and a normal platelet count. The marrow was heavily fibrotic, and no aspirate material could be obtained; the biopsy showed extensive infiltration with small to medium size megakaryocytes, dysplastic changes in the erythroid compartment, and left shift in the myeloid cells. The patient was treated for four months with anabolic steroids (Danazol, growth factors and received regular blood transfusions. At 4 months after diagnosis, the patient was started on Lenalidomide, 10 mg/day for a 21-d-course along with growth factor support. At 6 months after treatment, the patient was transfusion-independent, had normalized blood counts, and, at 32 months on continuous lenalidomide treatment, her needs for growth factor support have been minimized. Repeat bone marrow biopsies showed a patchy distribution of fibrosis with areas of normal cellularity and morphology. To our knowledge, this is the first case for a medication that could reverse the fatal outcome of APMF.

    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.

    George, Paul E; Vidal, Julio; Garcia, Patricia J

    2016-01-01

    Background Peru experienced a crisis in its blood collection and supply system in the mid-2000s, as contaminated blood led to several transfusion-transmitted infections (TTI), occurring in the backdrop of extremely low voluntary donation rates and a national blood supply shortage. Thus, the Peruvian Ministry of Health (MINSA) implemented a national investigation on the safety and quality of the Peruvian blood collection/transfusion network. Methods Every Peruvian blood bank was evaluated by MINSA from 2007–2008. These evaluations consisted of an update of the national registry of blood banks and visits to each blood bank from MINSA oversight teams. Information was collected on the condition of the blood bank personnel, equipment, supplies, and practices. Further, previously-collected blood at each blood bank was randomly selected and screened for TTI-causing pathogens. Results Uncovered in this investigation was a fragmented, under-equipped, and poorly-staffed blood collection and transfusion network, consisting of 241 independent blood banks and resulting in suboptimal allocation of resources. Further, blood with evidence of TTI-causing pathogens (including Hepatitis B, Hepatitis C, and syphilis) and set for transfusion was discovered at three separate blood banks as part of the random screening process. Conclusion Using the successful reorganizations of national blood supply systems in other Latin American countries as examples, Peru would be well-served to form large, high-volume, regional blood collection and transfusion centers, responsible for blood collection and screening for the entire country. The small, separate blood banks would then be transformed into a network of blood transfusion centers, not responsible for blood collection. This reorganization would allow Peru to better utilize its resources, standardize the blood collection and transfusion process, and increase voluntary donation, resulting in a safer, more abundant national blood product.

    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.

  15. Almonte's great train disaster: Shaping nurses' roles and the civilian use of blood transfusion.

    Science.gov (United States)

    2004-01-01

    Blood transfusion was initially a small-scale, labour-intensive therapy administered by physicians. Through the first decades of the 20th century, transfusion comprised a "last resort" measure used and tested primarily in the context of war. Media accounts of the Almonte train disaster on the night of 27 December 1942 linked survival to the newly established blood bank located 42 km east in Ottawa, Ontario. This event did not constitute a "first time" occurrence or a "great discovery" in the history of blood. But it did illustrate in a very visible and public manner that blood transfusion technology was now readily available for use in general hospitals and civilian populations. Canada had an infrastructure for the collection, processing, storage, and transportation of blood products, and for the recruitment of blood donors by the mid-1940s. As the need for blood declined toward the end of World War II, transfusion became a technology in need of application. The extension of transfusion to civilian populations, however, would require a ready source of labour-increased numbers of health care workers who were available continuously with the necessary knowledge and skills to assume the responsibility. Nurses were well situated for this technological role by a convergence of scientific, economic, labour, gender, professional, and educational influences that both facilitated and constrained blood transfusion as a nursing competency. This paper examines how the expanded use of one medical technology shaped related roles for nurses. Transfusion ultimately influenced nurses' work and the composition of the workforce as the first medical act "delegated" to nurses in Ontario (1947), setting a precedent for the delegation of further technologies over the next four decades.

    Little is known about the impact of posttransplant blood transfusion on the sensitization of anti-HLA antibodies and the formation of donor-specific antibodies (DSAs). The aims of our study were to determine the 1-year incidence of DSAs (assessed using a solid-phase assay) and antibody-mediated rejection (AMR) in kidney transplant patients who had or had not received a blood transfusion during the first year after transplantation. Included were 390 non-HLA-sensitized patients who had received an ABO-compatible kidney transplant and had not previously or simultaneously received a nonkidney transplant. Overall, 64% of patients received a red blood cell transfusion within the first year after transplantation, most within the first month. The overall 1-year incidence of DSAs was significantly higher in patients that had undergone transfusion (7.2% vs. 0.7% in patients with no transfusion, p transfusion group (n = 15, 6%) compared with the nontransfusion group (n = 2, 1.4%; p = 0.04). Blood transfusion was an independent predictive factor for de novo DSA formation but not for AMR. Patients who had a transfusion and developed DSAs were more often treated with cyclosporin A (n = 10, 55.5%) rather than tacrolimus (n = 45, 19.4%; p = 0.0001). In conclusion, early posttransplant blood transfusion may increase immunological risk, especially in underimmunosuppressed patients.

    Laboratory testing prior to blood transfusion outside of regular hours in many hospitals and clinics is frequently conducted by technicians without sufficient experience in such testing work. To obtain consistent test results regardless of the degree of laboratory experience with blood transfusion testing, the number of facilities introducing automated equipment for testing prior to blood transfusion is increasing. Our hospital's blood transfusion department introduced fully automated test equipment in October of 2010 for use when blood transfusions are conducted outside of regular hours. However, excessive dependence on automated testing can lead to an inability to do manual blood typing or cross-match testing when necessitated by breakdowns in the automated test equipment, in the case of abnormal specimen reactions, or other such case. In addition, even outside of normal working hours there are more than a few instances in which transfusion must take place based on urgent communications from clinical staff, with the need for prompt and flexible timing of blood transfusion test and delivery of blood products. To address this situation, in 2010 we began training after-hours laboratory personnel in blood transfusion testing to provide practice using test tubes manually and to achieve greater understanding of blood transfusion test work (especially in cases of critical blood loss). Results of the training and difficulties in its implementation for such after-hours laboratory personnel at our hospital are presented and discussed in this paper. [Original

  19. Risk perception and its role in attitudes toward blood transfusion: a qualitative systematic review.

    Ngo, Ly Thi; Bruhn, Roberta; Custer, Brian

    2013-04-01

    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

    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.

    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

    Safety concerns combined with the greatly increased costs and difficulties of maintaining the blood supply are major considerations for transfusion services. Previous local surveys demonstrated that hospital blood use at our hospital could be improved. Excessive cross-matching, unnecessary transfusion and high return rates of unused blood were commonplace. Transfusion practice was audited over a 3-month period. An education package with guidelines for transfusion was delivered to all clinician groups within the hospital, over the following 9 months. The audit was repeated exactly 1 year later at the same time period. During the second audit, inpatient hospital numbers increased by 1.02% (from n = 7262 to n = 7336) but no differences in length of stay, cardiovascular morbidity or mortality were demonstrated. Twenty percent (n = 254, 2002; n = 316, 2001) fewer patients received blood, and the number of red cell packs used reduced by 19% (from n = 1093 to n = 880). Total number of patients transfused reduced from 4.4% to 3.5% which, as an absolute difference, is a reduction of 0.9% (CI 0.3-1.5, P = 0.006). The audit, guideline and education package had a major impact on red cell use within the hospital with no adverse effects. Blood use can be improved by the implementation of a suitable education package and guideline. If it is possible to replicate the results of this education programme nationwide, the effect on blood use, with subsequent savings and enhanced patient safety could be significant.

  3. 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.

  4. Changes in electrolytes and blood gas after transfusion of irradiated MAP

    International Nuclear Information System (INIS)

    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.

    There has been little blood safety research in sub-Saharan Africa, often consisting of local efforts whose findings had limited impact The "Francophone Africa Transfusion Research Network" was created in May 2007 with the objective of developing common evidence-based blood safety policies that may be adapted to each country's situation. The Group's activities to date have focused mainly on obtaining epidemiological and laboratory data on blood transfusion and on suggesting blood safety strategies, particularly in the field of TTIs. To carry out such research activities, the group works closely with the National Blood Transfusion Services (NBTS), the Regional Blood Transfusion Services (RBTS), the hospital blood banks (HBB) and collection stations. For the first 5years, four research priorities were identified: (i) descriptive studies of the characteristics of francophone African blood donors and blood centers; (ii) estimation of the residual risk of transfusion-transmitted major viral infections; (iii) an analysis of blood donor deferral strategies; and (iv) a description of TTI screening strategies and an external quality assurance system (EQAS) project. During this period, seven projects have been implemented at the national level and published and five multicenter studies were conducted and published. The present review reports the main observations and recommendations from those studies that could improve blood safety statute in Africa.

    Twin-twin transfusion syndrome (TTTS) is a severe complication of monozygotic (identical) twins, which share one single monochorionic placenta. It is caused by placental anastomoses which link the two fetoplacental circulations of the twins and allow a chronic net inter-twin transfusion to develop between the fetuses. Clinical presentation of TTTS manifestations has been classified into five different stages. In this paper, we used our computational model of TTTS and examined the possible differences between chronic and rapidly increasing inter-twin transfusion in the simulated TTTS staging sequence. Our results suggest that rapid alterations in the net inter-twin transfusion, e.g. due to thrombosis of placental anastomoses, may produce a different staging sequence than in TTTS caused by chronic inter-twin transfusion. These results may aid an improved knowledge of TTTS pathophysiology under conditions of a rapidly changing cardiovascular function, and contribute to the planning of optimal intervention under such circumstances.

    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.

    BACKGROUND: Although mechanisms for detection of short-term complications after blood transfusions are well developed, complications with delayed onset, notably transmission of chronic diseases such as cancer, have been difficult to assess. Our aim was to investigate the possible risk of cancer...... transmission from blood donors to recipients through blood transfusion. METHODS: We did a register-based retrospective cohort study of cancer incidence among patients who received blood from donors deemed to have a subclinical cancer at the time of donation. These precancerous donors were diagnosed......, and essentially complete, population and health-care registers. The risk of cancer in exposed recipients relative to that in recipients who received blood from non-cancerous donors was estimated with multivariate Poisson regression, adjusting for potential confounding factors. FINDINGS: Of the 354 094 transfusion...

    When gas flows in a compact porous medium at low speed, it has a slippage effect which is caused by molecular collisions of gas with the solid skeleton. Using the gas transfusion slippage effect for researching coal bed transfusion, a mathematical model of the coal bed was established which considered the slippage effect. The experiment indicates that the higher the surrounding pressure, the more marked is the slippage effect. At the same condition of axial pressure and surrounding pressure, with an increase of the hole pressure, the coal permeability become higher and then lower. The coal body effective stress and the permeability curve also has the same change tendency. Thus the conclusion can be drawn that the transfusion of the gas in the coal bed generally has a slippage effect. 5 refs., 3 figs.

    To mitigate medical risks in remote environments, the authors have implemented an innovative integrated medical support solution for bleeding management on board ships since 2013. Fresh whole blood transfusion (FWBT) and lyophilised plasma were put in place to address life threatening haemorrhages in maritime operations in the Arctic and Antarctica. The authors are illustrating the bleeding risks with an actual case occurring in Antarctica prior to the implementation of these procedures. They are presenting the different steps involved in the complex process of FWBT, from blood donors' qualifications to actual transfusions. The pros and cons of blood transfusion in extreme remote environment are discussed, including the training of health care professionals, equipment requirements, legal and ethical issues, decision making in complex blood group matching, medical benefits and risks.

    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.

    Full Text Available MicroRNAs (miRNAs are small non-coding RNAs that regulate various biological processes. Cell-free miRNAs measured in blood plasma have emerged as specific and sensitive markers of physiological processes and disease. In this study, we investigated whether circulating miRNAs can serve as biomarkers for the detection of autologous blood transfusion, a major doping technique that is still undetectable. Plasma miRNA levels were analyzed using high-throughput quantitative real-time PCR. Plasma samples were obtained before and at several time points after autologous blood transfusion (blood bag storage time 42 days in 10 healthy subjects and 10 controls without transfusion. Other serum markers of erythropoiesis were determined in the same samples. Our results revealed a distinct change in the pattern of circulating miRNAs. Ten miRNAs were upregulated in transfusion samples compared with control samples. Among these, miR-30b, miR-30c, and miR-26b increased significantly and showed a 3.9-, 4.0-, and 3.0-fold change, respectively. The origin of these miRNAs was related to pulmonary and liver tissues. Erythropoietin (EPO concentration decreased after blood reinfusion. A combination of miRNAs and EPO measurement in a mathematical model enhanced the efficiency of autologous transfusion detection through miRNA analysis. Therefore, our results lay the foundation for the development of miRNAs as novel blood-based biomarkers to detect autologous transfusion.

    The administration of blood products is a common, resource-intensive, and potentially problem-prone area that may place patients at elevated risk in the clinical setting. Much of the emphasis in transfusion safety has been targeted toward quality control measures in laboratory settings where blood products are prepared for administration as well as in automation of certain laboratory processes. In contrast, the process of transfusing blood in the clinical setting (ie, at the point of care) has essentially remained unchanged over the past several decades. Many of the currently available methods for improving the quality and safety of blood transfusions in the clinical setting rely on informal process descriptions, such as flow charts and medical algorithms, to describe medical processes. These informal descriptions, although useful in presenting an overview of standard processes, can be ambiguous or incomplete. For example, they often describe only the standard process and leave out how to handle possible failures or exceptions. One alternative to these informal descriptions is to use formal process definitions, which can serve as the basis for a variety of analyses because these formal definitions offer precision in the representation of all possible ways that a process can be carried out in both standard and exceptional situations. Formal process definitions have not previously been used to describe and improve medical processes. The use of such formal definitions to prospectively identify potential error and improve the transfusion process has not previously been reported. The purpose of this article is to introduce the concept of formally defining processes and to describe how formal definitions of blood transfusion processes can be used to detect and correct transfusion process errors in ways not currently possible using existing quality improvement methods.

    Hemoglobinopathies are significant health problems in Iraq, including its Northern Kurdistan region. One of the essential components of management of these disorders is regular lifelong blood transfusions. The latter is associated with several complications including red cell alloimmunization. No study has looked at the frequency of alloimmunization and its associations in the country. To address the latter issue, 401 multi transfused patients [311 with β-thalassemia (β-thal) syndrome and 90 with sickle cell disease], registered at a large thalassemia care center in Iraqi Kurdistan had their records reviewed, and their sera tested for atypical antibodies using screening and extended red cell panels. Red cell alloimmunization was detected in 18 patients (4.5%) with a total of 20 alloantibodies, while no autoantibodies were detected. The most frequent alloantibody was anti-E, followed by anti-D, anti-K, anti-C(w), anti-C, anti-c and anti-Le(a). Ethnicity was an important predictor of alloimmunization, while age at start of transfusion (>2 vs. ≤2 years) (p = 0.005), Rhesus D (RhD) negative status (p = 0.0017) and history of previous transfusion reactions (p = 0.007) showed a statistically significant higher rate of alloimmunization. However, patients' age, gender, number of units transfused, underlying diagnosis and splenectomy were not significantly associated with alloimmunization. Based on our observations, measures to reduce alloimmunization rates may include extended matching for Rhesus and Kell antigens and early initiation of blood transfusions. PMID:26327166

    Full Text Available Objectives: Regular blood transfusions are essential for patients with thalassaemia major. However, infections with hepatotropic viruses remain a major concern. The objective of this study was to evaluate the prevalence and characteristics of hepatitis C viral (HCV infection among patients with homozygous beta thalassaemia in a single centre in Oman. Methods: A retrospective chart review of 200 patients treated at the Thalassemia Unit of Sultan Qaboos University Hospital (SQUH in Muscat, Oman, between August 1991 and December 2011 was performed. Relevant demographic and clinical characteristics were collected, including age, gender, HCV status and the presence of endocrinopathies. Results: A total of 81 patients (41% were found to be anti-HCV-antibody (anti-HCV-positive. HCV ribonucleic acid tests were performed on 65 anti-HCV-positive patients and were positive among 33 (51%; the remaining 16 patients died before these tests were available. Anti-HCV-positive patients were significantly older than anti-HCV-negative patients (P <0.001 and were more likely to be diabetic than anti-HCV-negative patients (27% versus 8%; P <0.001. A total of 100 patients had been transfused before they were transferred to SQUH in 1991; of these, 70 (70% were anti-HCV-positive. Only 11 (11.5% of the 96 patients who were seronegative in 1991, or who were transfused later, became seropositive. Conclusion: It is likely that the high prevalence of HCV among multi-transfused thalassaemic patients in Oman is due to blood transfusions dating from before the implementation of HCV screening in 1991 as the risk of HCVassociated transfusions has significantly reduced since then. Additionally, results showed that anti-HCV-positive patients were more likely to be diabetic than anti-HCV-negative patients.

    Full Text Available Introduction: Errors in the process of pretransfusion testing for blood transfusion can occur at any stage from collection of the sample to administration of the blood component. The present study was conducted to analyze the errors that threaten patients′ transfusion safety and actual harm/serious adverse events that occurred to the patients due to these errors. Materials and Methods: The prospective study was conducted in the Department Of Transfusion Medicine, Shri Maharaja Gulab Singh Hospital, Government Medical College, Jammu, India from January 2014 to December 2014 for a period of 1 year. Errors were defined as any deviation from established policies and standard operating procedures. A near-miss event was defined as those errors, which did not reach the patient. Location and time of occurrence of the events/errors were also noted. Results: A total of 32,672 requisitions for the transfusion of blood and blood components were received for typing and cross-matching. Out of these, 26,683 products were issued to the various clinical departments. A total of 2,229 errors were detected over a period of 1 year. Near-miss events constituted 53% of the errors and actual harmful events due to errors occurred in 0.26% of the patients. Sample labeling errors were 2.4%, inappropriate request for blood components 2%, and information on requisition forms not matching with that on the sample 1.5% of all the requisitions received were the most frequent errors in clinical services. In transfusion services, the most common event was accepting sample in error with the frequency of 0.5% of all requisitions. ABO incompatible hemolytic reactions were the most frequent harmful event with the frequency of 2.2/10,000 transfusions. Conclusion: Sample labeling, inappropriate request, and sample received in error were the most frequent high-risk errors.

    Full Text Available Background and Objectives. There is no data analyzing the outcome of blood transfusions and oral iron therapy in patients with kidneys failure in sub-Saharan Africa. 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. For patients undergoing regular transfusion we recommend routine serum ferritin measurement and yearly measurement of LIC.

    Full Text Available Introduction & Objective: Cellular blood products such as whole blood, packed RBC and platelet concentrate may contain a large number of donor leukocytes. These transfused cells are responsible for several transfusion reactions which include febrile reactions, platelet refractoriness due to alloimmunization and some cell associated virus transmission, especially cytomegalovirus. Advances in biotechnology resulted in production of filters capable of depleting residual leukocytes below the threshold receded to prevent these complications. The aim of this study was to determine the efficacy of prestorage and poststorage leukocyte reduction filters.Materials & Methods: In this experimental study 140 leukocyte filters used in patients with major thalassemia with age range of 1 to 18 years old were studied. They received packed RBC with pre storage or post storage filtration in pediatric hematology clinic of Be’sat hospital, Hamadan,Iran. In addition to filter efficiency, some transfusion reactions such as hypotension, urticaria, flushing, fever and chills were analyzed with chi-square and independent t-test.Results: Calculated efficiencies of pre storage and post storage filtration were 99.70%±69% and 92.74%±12.47% respectively, which is statistically significant (P=0.000. Fever, chills, urticaria and flushing which are some transfusion reactions, were not seen in any patients received filtrated packed RBC. No transfusion complication except hypotension (which was seen in 14 patients in both groups was seen. Maximum remained leukocyte in pre storage packed RBC was 20/mm3 and 524/mm3 in post storage blood.Conclusion: According to the calculated standard deviation, pre storage leukocyte filters are superior to post storage filters, and so post storage filtration is not a reliable method to reduce remaining white blood cells in transfused blood.
