    Transfusion-related acute lung injury (TRALI) refers to a clinical syndrome of acute lung injury that occurs in a temporal relationship with the transfusion of blood products. Because of the difficulty in making its diagnosis, TRALI is often underreported. Three not necessarily mutually exclusive hypotheses have been described to explain its etiogenesis: antibody mediated, non-antibody mediated, and two hit mechanisms. Treatment is primarily supportive and includes supplemental oxygen. Diuretics are generally not indicated, as hypovolemia should be avoided. Compared with many other forms of acute lung injury, including the acute respiratory distress syndrome, TRALI is generally transient, reverses spontaneously, and carries a better prognosis. A variety of prevention strategies have been proposed, ranging from restrictive transfusion strategies to using plasma derived only from males.

    Respiratory complications of blood transfusion have several possible causes. Transfusion-Associated Circulatory Overload (TACO) is often the first mentioned. Transfusion-Related Acute Lung Injury (TRALI), better defined since the consensus conference of Toronto in 2004, is rarely mentioned. French incidence is low. Non-hemolytic febrile reactions, allergies, infections and pulmonary embolism are also reported. The objective of this work was to determine the statistical importance of the different respiratory complications of blood transfusion. This work was conducted retrospectively on transfusion accidents in six health centers in Champagne-Ardenne, reported to Hemovigilance between 2000 and 2009 and having respiratory symptoms. The analysis of data was conducted by an expert committee. Eighty-three cases of respiratory complications are found (316,864 blood products). We have counted 26 TACO, 12 TRALI (only 6 cases were identified in the original investigation of Hemovigilance), 18 non-hemolytic febrile reactions, 16 cases of allergies, 5 transfusions transmitted bacterial infections and 2 pulmonary embolisms. Six new TRALI were diagnosed previously labeled TACO for 2 of them, allergy and infection in 2 other cases and diagnosis considered unknown for the last 2. Our study found an incidence of TRALI 2 times higher than that reported previously. Interpretation of the data by a multidisciplinary committee amended 20% of diagnoses. This study shows the imperfections of our system for reporting accidents of blood transfusion when a single observer analyses the medical records.

    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.

    Von Willebrand disease (vWD) is the most common inherited bleeding disorder based on an autosomal abnormality of von Willebrand factor. Transfusion is a lifesaving medical intervention among patients with bleeding disorders. Patients with vWD are exposed to Transfuse Related Acute Lung Injury (TRALI) when they become recipients of multiple blood products and repeated transfusions. TRALI is a non-hemolytic transfusion reaction induced by infusions of intravenous immunoglobulin, platelets (suspended in plasma), whole blood, cryoprecipitates, and fresh frozen plasma (FFP). We report a 14 years old white girl, with a history of type 1 von Willebrand disease (vWd), recipient of 2 units' fresh-frozen plasma (FFP) and 1 unit whole blood transfusion who developed an acute respiratory distress with severe hypoxemia and bilateral pulmonary infiltrate on chest X-ray within 3 hours of the whole blood transfusion, completely reversible after mechanical ventilation. Concluding, patients with vWd who received recurrent transfusions have an increased risk of TRALI. Physicians must be familiar with it as a cause of white lung X-ray pattern.

    Approximately one person in 5,000 will experience an episode of transfusion-related acute lung injury (TRALI) in conjunction with the transfusion of whole blood or blood components. Its hallmarks include hypoxemia, dyspnea, fever, hypotension, and bilateral pulmonary edema (noncardiogenic). The mortality for reported cases is 16.3%. The incidence and mortality may be even higher than estimated because of under-recognition and under-reporting. Although TRALI was identified as a clinical entity in the 1980s, a lack of consensus regarding a definition was present until 2004. An exact cause has yet to be identified; however, there are two theories regarding the etiology: the "antibody" and the "two-hit" theories. These theories involve both donor and recipient factors. Further education and research are needed to assist in the development of strategies for the prevention and treatment of TRALI.

    Transfusion-related acute lung injury (TRALI) is a severe life-threatening complication of blood transfusion, characterized by acute lung injury developing within 2-6 h of transfusion. However, TRALI is difficult to diagnose, and the initial report or suspicion of TRALI depends on close collaboration between clinical departments and transfusion centres. A total of 17 adverse post-transfusion reactions were reported to the Blood Centre of the University Hospital Ostrava as suspected TRALI between 2005 and 2010. We report two cases of serious TRALI with different pathogenetic mechanisms.

    Full Text Available Transfusion associated circulatory overload (TACO and transfusion related acute lung injury (TRALI are two dissimilar pathological conditions associated with transfusion of blood products where the time course of the events and clinical presentation overlap leading to uncertainty in establishing the diagnosis and initiating the treatment, which otherwise differs. We encountered a case where a patient of post-partum hemorrhage developed TACO in the immediate post-operative period due to aggressive resuscitative attempts with blood products. The patient′s condition was appropriately diagnosed and was managed according to the clinical scenario, and the condition abated. Subsequently, on the third post-operative day the patient again required blood product transfusions following which the patient developed TRALI, the diagnosis of which was also established and adequate treatment strategy was undertaken.

    Three children are described in whom pre-transfusion samples were HIV-seronegative and post-transfusional samples, obtained within 1 week after transfusion, were HIV-seropositive. Two of them developed a transient fever within 1 week of receiving the blood transfusion, and a transient generalized skin eruption which lasted for about 2 weeks. All three developed persistent generalized lymphadenopathy. One child developed a lumbar herpes zoster 7 months after transfusion. IgM Western blots demonstrated the presence of antibodies to protein bands p17, p24 and p55 in all three children. These three case reports suggest that children who receive a seropositive blood transfusion are at high risk for developing acute manifestations of HIV infection.

    Full Text Available Abstract Introduction Transfusion-related acute lung injury is emerging as a common cause of transfusion-related adverse events. However, awareness about this entity in the medical fraternity is low and it, consequently, remains a very under-reported and often an under-diagnosed complication of transfusion therapy. Case presentation We report a case of a 46-year old woman who developed acute respiratory and hemodynamic instability following a single unit blood transfusion in the postoperative period. Investigation results were non-specific and a diagnosis of transfusion-related acute lung injury was made after excluding other possible causes of acute lung injury. She responded to symptomatic management with ventilatory and vasopressor support and recovered completely over the next 72 hours. Conclusion The diagnosis of transfusion-related acute lung injury relies on excluding other causes of acute pulmonary edema following transfusion, such as sepsis, volume overload, and cardiogenic pulmonary edema. All plasma containing blood products have been implicated in transfusion-related acute lung injury, with the majority being linked to whole blood, packed red blood cells, platelets, and fresh-frozen plasma. The pathogenesis of transfusion-related acute lung injury may be explained by a "two-hit" hypothesis, involving priming of the inflammatory machinery and then activation of this primed mechanism. Treatment is supportive, with prognosis being substantially better than for most other causes of acute lung injury.

    Transfusion-related acute lung injury (TRALI) is a life-threatening complication of transfusion. Greater understanding of the pathophysiology of this syndrome has much improved during the last two decades. Plasma-containing components from female donors with leucocyte antibodies were responsible for the majority of TRALI fatalities before mitigation strategies were implemented. Over the past 15 years, measures to mitigate risk for TRALI have been implemented worldwide and they continued to evolve with time. The AABB requires that all plasma containing components and whole blood for transfusion must be collected from men, women who have not been pregnant, or women who have tested negative for human leucocyte antigen antibodies. Although the incidence of TRALI has decreased following the institution of TRALI mitigation strategies, TRALI is still the most common cause of transfusion-associated death in the United States. In this review, we focus on TRALI risk mitigation strategies. We describe the measures taken by blood collection facilities to reduce the risk of TRALI in the United States, Canada and European countries. We also review the literature for the effectiveness of these measures. © 2017 International Society of Blood Transfusion.

    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.

    Full Text Available Lesão pulmonar aguda associada à transfusão (transfusion-related acute lung injury, TRALI é uma complicação clínica grave relacionada à transfusão de hemocomponentes que contêm plasma. Recentemente, TRALI foi considerada a principal causa de morte associada à transfusão nos Estados Unidos e Reino Unido. É manifestada tipicamente por dispnéia, hipoxemia, hipotensão, febre e edema pulmonar não cardiogênico, que ocorre durante ou dentro de 6 h, após completada a transfusão. Embora o exato mecanismo não tenha sido totalmente elucidado, postula-se que TRALI esteja associada à infusão de anticorpos contra antígenos leucocitários (classes I ou II ou aloantígenos específicos de neutrófilos e a mediadores biologicamente ativos presentes em componentes celulares estocados. A maioria dos doadores implicados em casos da TRALI são mulheres multíparas. TRALI, além de ser pouco diagnosticada, pode ainda ser confundida com outras situações de insuficiência respiratória aguda. Um melhor conhecimento sobre TRALI pode ser crucial na prevenção e tratamento desta severa complicação transfusional.Transfusion-related acute lung injury (TRALI is a serious clinical syndrome associated with the transfusion of plasma-containing blood components.

This complication typically presents as shortness of breath, hypoxemia, hypotension, fever and noncardiogeneic pulmonary edema, all occurring during or within 6 h after transfusion. Although the mechanism of TRALI has not been fully elucidated, it has been associated with human leukocyte antigen antibodies (class I, class II or neutrophil alloantigens and with biologically active mediators in stored cellular blood components. Most of the donors implicated in cases of TRALI are multiparous women. Rarely diagnosed, TRALI can be confused with other causes of acute

    Transfusion is an irreversible event which carries potential benefits as well as risk to the recipient. The objective of this study was to analyse all reported transfusion reactions of the year 2008 in the Blood Bank Unit of Universiti Kebangsaan Malaysia Medical Centre (UKMMC). This is a retrospective study that was carried out by retrieving data from the laboratory information system. A total of 27842 transfusions were documented and the total reported transfusion reactions were 149. The incidence of transfusion reaction was 1 in 187 of all transfusions (0.54%); in which 69 (0.25%) were allergic in nature and 61 (0.22%) were febrile non-haemolytic transfusion reactions (FNHTR). Hypotensive reactions were identified in 6 (0.02%) patients. There were 9 (0.03%) cases reported with haemoglobinuria where no serological evidence of haemolytic transfusion reaction (HTR) was found. One HTR (0.003%) was identified and this was due to an error in patient identification in the ward. Other specified reactions like transfusion-related acute lung injury (TRALI), bacterial infections, Graft verses host disease (GVHD) were not reported. The highest frequency of the reactions occurred in the red cell transfusions which accounted for 111 cases. In conclusion, the incidences of transfusion reactions are low when compared to those reported by other centres.

    Full Text Available Rhesus (Rh mediated hemolytic transfusion reactions (HTR are usually immunoglobulin G mediated and delayed onset. Rh antibodies being the cause of acute HTR (AHTR and intravascular hemolysis are still under debate. We report here a case of a 53-year-old male who developed AHTR due to "anti-c" antibodies within 3 h of blood transfusion, precipitating fatal acute liver failure in a patient with hepatitis C related chronic liver disease. This case emphasizes the need of inclusion of antibody screening in routine pretransfusion testing as well as a critical role of transfusion medicine specialists for early diagnosis and minimizing transfusion-related morbidity and mortality.

    A 10-year-old male with acute leukemia presented with post-chemotherapy anemia. During red cell transfusion, he developed hemoglobinuria. Transfusion reaction workup was negative. Drug-induced immune hemolytic anemia was suspected because of positive direct antiglobulin test, negative eluate, and microspherocytes on smear pre- and post-transfusion. Drug studies using the indirect antiglobulin test were strongly positive with trimethoprim and trimethoprim-sulfamethoxazole but negative with sulfamethoxazole. The patient recovered after discontinuing the drug, with no recurrence in 2 years. Other causes of anemia should be considered in patients with worse-than-expected anemia after chemotherapy. Furthermore, hemolysis during transfusion is not always a transfusion reaction.

    The management model based on risk prevention has become a major influence in shaping policies for transfusion safety. There are approximately sixty interactions between the health worker and the patient during the transfusion process,representing the number of times where you have the opportunity to make a mistake.We present an analysis of the weaknesses of the National Blood System, with particular attention to the haemovigilance donor and patient. The proposals include the implementation of the National Blood containing the need to establish from the National Blood Safety, significant changes in the regulatory framework and the internal regulations of the Ministry of Health, the CNTS and COFEPRIS. Is required to promote and coordinate the collection of accurate information from the committees of transfusion medicine, which will be accompanied by an initial diagnosis from the National Survey of Blood. Requires notice to other forms of funding to ensure the viability of the projects operating blood bank. Finally, as a strategic resource, the blood is of public, so access should not be restricted.

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.

    Full Text Available A 46 year old man was transfused ten units of packed red blood cells during subtotal colectomy after intraoperative point-of-care testing values demonstrated hemoglobin values less than seven grams per deciliter (g/dL. A post-operative hemoglobin analyzed in a standard hematologic laboratory revealed a hemoglobin value of 27.8 g/dL. He underwent emergent red blood cell depletion therapy which decreased his hemoglobin to 7.5 g/dL. The physiologic consequences of iatrogenic polycythemia caused by massive transfusion during major abdominal surgery must take into account the fluid shifts that interplay between the osmotic load, viscosity of blood, and postoperative third spacing of fluid. Treatment of acute iatrogenic polycythemia can be effectively accomplished by red blood cell depletion therapy. However, fluid shifts caused by massive transfusion followed by rapid red cell depletion produce a unique physiologic state that is without a well-described algorithm for management.

    Recommendations concerning the management of hemoglobin levels and hematocrit in patients on extracorporeal membrane oxygenation (ECMO) still advise maintenance of a normal hematocrit. In contrast, current transfusion guidelines for critically ill patients support restrictive transfusion practice. We report on a series of patients receiving venovenous ECMO (vvECMO) for acute respiratory distress syndrome (ARDS) treated according to the restrictive transfusion regimen recommended for critically ill patients. We retrospectively analyzed 18 patients receiving vvECMO due to severe ARDS. Hemoglobin concentrations were kept between 7 and 9 g/dL with a transfusion trigger at 7 g/dL or when physiological transfusion triggers were apparent. We assessed baseline data, hospital mortality, time on ECMO, hemoglobin levels, hematocrit, quantities of packed red blood cells received, and lactate concentrations and compared survivors and nonsurvivors. The overall mortality of all patients on vvECMO was 38.9%. Mean hemoglobin concentration over all patients and ECMO days was 8.30 ± 0.51 g/dL, and hematocrit was 0.25 ± 0.01, with no difference between survivors and nonsurvivors. Mean numbers of given PRBCs showed a trend towards higher quantities in the group of nonsurvivors, but the difference was not significant (1.97 ± 1.47 vs. 0.96 ± 0.76 units; P = 0.07). Mean lactate clearance from the first to the third day was 45.4 ± 28.3%, with no significant difference between survivors and nonsurvivors (P = 0.19). In our cohort of patients treated with ECMO due to severe ARDS, the application of a restrictive transfusion protocol did not result in an increased mortality. Safety and feasibility of the application of a restrictive transfusion protocol in patients on ECMO must further be evaluated in randomized controlled trials.

    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.

    The accumulation of non-polar lipids arachidonic acid, 5-hydroxyeicosatetraenoic acid (HETE), 12-HETE and 15-HETE during storage of transfusion products may play a role in the onset of transfusion-related acute lung injury (TRALI), a syndrome of respiratory distress after transfusion. We investigated non-polar lipid accumulation in red blood cells (RBCs) stored for 42 days, plasma stored for 7 days at either 4 or 20°C and platelet (PLT) transfusion products stored for 7 days. Furthermore, we investigated whether transfusion of RBCs with increased levels of non-polar lipids induces TRALI in a 'two-hit' human volunteer model. All products were produced following Dutch Blood Bank protocols and are according to European standards. Non-polar lipids were measured with high-performance liquid chromotography followed by mass spectrometry. All non-polar lipids increased in RBCs after 21 days of storage compared to baseline. The non-polar lipid concentration in plasma increased significantly, and the increase was even more pronounced in products stored at 20°C. In platelets, baseline levels of 5-HETE and 15-HETE were higher than in RBCs or plasma. However, the non-polar lipids did not change significantly during storage of PLT products. Infusion of RBCs with increased levels of non-polar lipids did not induce TRALI in LPS-primed human volunteers. We conclude that non-polar lipids accumulate in RBC and plasma transfusion products and that accumulation is temperature dependent. Accumulation of non-polar lipids does not appear to explain the onset of TRALI (Dutch Trial Register - NTR4455). © 2016 International Society of Blood Transfusion.

Acute lung injury (ALI recurred 31 days after the first ALI episode. Both ALI episodes occurred 48 hours after transfusion. Laboratory examinations revealed the presence of various antileukocyte antibodies including antiplatelet antibody in the recipient's serum but not in the donors' serum. The authors speculate that antiplatelet antibodies can have an inhibitory effect in the recipient, which can modulate the bona fide procedure of ALI and lead to a delay in the onset of ALI. This case illustrates the crucial role of a recipient's platelets in the development of TRALI.Keywords: delayed TRALI syndrome, recurrence, anti-platelet antibody

    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.

    A patient with B+ sickle cell disease received 3 units of red blood cells (RBCs) from two O+ donors and developed fever and hypotension after the first unit, consistent with an acute transfusion reaction (ATR). Anti-B titers in plasma from each O+ donor were markedly elevated and nondiscriminatory. In order to evaluate the potential for the transfused units to produce complement-mediated hemolysis of B+ RBCs, hemolytic complement testing was performed. Plasma from each donor was diluted in veronal buffer and incubated with B+ RBCs, and free hemoglobin was measured by spectrophotometer in the complement hemolysis using human erythrocytes (CHUHE) assay. Peptide inhibitor of complement C1 (PIC1) was used to confirm antibody-initiated complement pathway activation. A 96-fold difference (p = 0.014) in hemolysis was measured between plasma samples from the two O+ donors using the CHUHE assay. The extremely high degree of hemolysis produced by the one plasma was inhibited by PIC1 in a dose-dependent manner. These results indicate that hemolytic complement testing with the CHUHE assay can be used to assess the risk of antibody-initiated, complement-mediated hemolysis from a transfusion beyond what can be achieved with antibody titers alone. © 2016 AABB.

  14. The approach taken to reducing the risk of transfusion related acute lung injury in Canada

    2008-01-01

    Full Text Available 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.

    Acute upper gastrointestinal bleeding (AUGIB) is the commonest reason for hospitalization with hemorrhage in the UK and the leading indication for transfusion of red blood cells (RBCs). Observational studies suggest an association between more liberal RBC transfusion and adverse patient outcomes, and a recent randomised trial reported increased further bleeding and mortality with a liberal transfusion policy. TRIGGER (Transfusion in Gastrointestinal Bleeding) is a pragmatic, cluster randomized trial which aims to evaluate the feasibility and safety of implementing a restrictive versus liberal RBC transfusion policy in adult patients admitted with AUGIB. The trial will take place in 6 UK hospitals, and each centre will be randomly allocated to a transfusion policy. Clinicians throughout each hospital will manage all eligible patients according to the transfusion policy for the 6-month trial recruitment period. In the restrictive centers, patients become eligible for RBC transfusion when their hemoglobin is bleeding, mortality, thromboembolic events, and infections. Quality of life will be measured using the EuroQol EQ-5D at day 28, and the costs associated with hospitalization for AUGIB in the UK will be estimated. Consent will be sought from participants or their representatives according to patient capacity for use of routine hospital data and day 28 follow up. The study has ethical approval for conduct in England and Scotland. Results will be analysed according to a pre-defined statistical analysis plan and disseminated in peer reviewed publications to relevant stakeholders. The results of this study will inform the feasibility and design of a phase III randomized trial. PMID:23706959

    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.

    2014-01-01

    Full Text Available Background and Aim: Autoimmune hemolytic anemia (AIHA is characterized by the production of autoantibodies directed against red cell antigens. Most patients of AIHA arrive in the emergency or out-patient department (OPD with severe anemia requiring urgent blood transfusion. Here we share our experience of managing these patients with incompatible blood transfusions and suggest the minimal test required to assure patient safety. Materials and Methods: A total of 14 patients admitted with severe anemia, diagnosed with AIHA and requiring blood transfusion urgently were included in the study. A series of immunohematological investigations were performed to confirm the diagnosis and issue "best match" packed red blood cells (PRBC to these patients. Results: A total of 167 PRBC units were crossmatched for 14 patients of which 46 units (28% were found to be best match ones and 26 (56.5% of these units were transfused. A mean turn around time of 222 min was observed in issuing the ′best match′ blood. Severe hemolysis was observed in all patients with a median hemoglobin increment of 0.88 g/dl after each unit PRBC transfusion. Conclusion: Decision to transfuse in AIHA should be based on the clinical condition of the patient. No critical patient should be denied blood transfusion due to serological incompatibility. Minimum investigations such as direct antiglobulin test (DAT, antibody screening and autocontrol should be performed to ensure transfusion safety in patients. All transfusion services should be capable of issuing "best match" PRBCs in AIHA.

    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.

    Transfusion thresholds for acute upper gastrointestinal bleeding are controversial. So far, only three small, underpowered studies and one single-centre trial have been done. Findings from the single-centre trial showed reduced mortality with restrictive red blood cell (RBC) transfusion. We aimed to assess whether a multicentre, cluster randomised trial is a feasible method to substantiate or refute this finding. In this pragmatic, open-label, cluster randomised feasibility trial, done in six university hospitals in the UK, we enrolled all patients aged 18 years or older with new presentations of acute upper gastrointestinal bleeding, irrespective of comorbidity, except for exsanguinating haemorrhage. We randomly assigned hospitals (1:1) with a computer-generated randomisation sequence (random permuted block size of 6, without stratification or matching) to either a restrictive (transfusion when haemoglobin concentration fell below 80 g/L) or liberal (transfusion when haemoglobin concentration fell below 100 g/L) RBC transfusion policy. Neither patients nor investigators were masked to treatment allocation. Feasibility outcomes were recruitment rate, protocol adherence, haemoglobin concentration, RBC exposure, selection bias, and information to guide design and economic evaluation of the phase 3 trial. Main exploratory clinical outcomes were further bleeding and mortality at day 28. We did analyses on all enrolled patients for whom an outcome was available. This trial is registered, ISRCTN85757829 and NCT02105532. Between Sept 3, 2012, and March 1, 2013, we enrolled 936 patients across six hospitals (403 patients in three hospitals with a restrictive policy and 533 patients in three hospitals with a liberal policy). Recruitment rate was significantly higher for the liberal than for the restrictive policy (62% vs 55%; p=0·04). Despite some baseline imbalances, Rockall and Blatchford risk scores were identical between policies. Protocol adherence was 96% (SD 10) in

    Objective:To study the expression of TLR4 and CD40 in activated macrophage surface after transfusion-related acute lung injury in rats. Methods:SD rats were selected as experimental animals, lipopolysaccharide and plasma were transfused in turn, animal models with transfusion-related acute lung injury (TRALI) were established, lung tissue was collected to detect wet to dry weight ratio as well as mRNA expression levels of TLR4, NF-κB, CD40, TNF-α, IL-1β, MIP-2 and GRP78, serum was collected to detect TNF-α, IL-1βand MIP-2 contents, and macrophages in peripheral blood were collected to detect mRNA expression levels of TLR4, NF-κB and CD40. Results:Lung tissue wet to dry weight ratio of TRALI group was significantly higher than that of Sham group;mRNA expression levels of TLR4, NF-κB and CD40 in macrophages of TRALI group were significantly higher than those of Sham group;mRNA expression levels of TLR4, NF-κB, CD40, TNF-α, IL-1β, MIP-2 and GRP78 in lung tissue of TRALI group were significantly higher than those of Sham group;serum TNF-α, IL-1βand MIP-2 contents of TRALI group were significantly higher than those of Sham group;SOD and GSH contents in lung tissue of TRALI group were lower than those of Sham group, and contents of MDA and 8-OhdG were higher than those of Sham group. Conclusion:Expression levels of TLR4 and CD40 in activated macrophage surface significantly increase after transfusion-related acute lung injury in rats, which will cause lung injury through inflammatory response, oxidative stress response, endoplasmic reticulum stress and others aspects.

    Transfusion of blood products can be life saving when used appropriately. It carries however at the same time a potential for morbidity and mortality, depending on the patient, the product or the setting. Numerous strategies have been elaborated to minimize these risks, and in recent years, transfusion has no longer been regarded as essential for the management of a wide range of diseases. Uncomplicated surgeries in well-prepared patients can now be conducted without the use of transfusions. Questions about transfusion safety and shortage have led to extensive research on alternatives to blood transfusion, ranging from non-pharmacological to pharmacological solutions. Restrictive transfusion therapies, preoperative autologous blood donations, perioperative red cell salvage, acute normovolaemic haemodilution techniques or patient blood management are potential solutions where prothrombin complex or fibrinogen concentrates, synthetic anti-fibrinolytic agents, desmopressin, rFVIIa, or erythropoiesis stimulating agents may play a complementary pharmacologic role.

    Full Text Available OBJECTIVE: Brazilian legislation has recently suggested the use of the qualitative hemolysin test instead of isohemagglutinin titers as prophylaxis for acute hemolysis related to plasma-incompatible platelet transfusions. The efficacy of this test in preventing hemolytic reactions has never been evaluated while isohemagglutinin titers have been extensively studied. The main objective of this study was to evaluate the correlation between the results of these two tests. The impact of each type of prophylaxis on the platelet inventory management and the ability of the qualitative hemolysin test to prevent red cell sensitization after the transfusion of incompatible units were also studied.METHODS: A total of 246 donor blood samples were evaluated using both isohemagglutinin titers and the qualitative hemolysin test, and the results were statistically compared. Subsequently, 600 platelet units were tested using the hemolysin assay and the percentage of units unsuitable for transfusion was compared to historical data using isohemagglutinin titers (cut-off: 100. Moreover, ten patients who received units with minor ABO incompatibilities that were negative for hemolysis according to the qualitative hemolysin test were evaluated regarding the development of hemolysis and red cell sensitization (anti-A or anti-B.RESULTS: Isohemagglutinin titration and the results of qualitative hemolysin test did not correlate. The routine implementation of the qualitative hemolysin test significantly increased the percentage of platelet units found unsuitable for transfusions (15-65%; p-value <0.001. Furthermore the qualitative hemolysin test did not prevent red blood cell sensitization in a small exploratory analysis.CONCLUSION: Qualitative hemolysin test results do not correlate to those of isohemagglutinin titers and its implementation as the prophylaxis of choice for hemolysis associated with plasma-incompatible platelet transfusions lacks clinical support of safety

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

    Viktoria M Doll

    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.

    2012-01-01

    Transfusion-related acute lung injury (TRALI) is a severe form of pulmonary insufficiency induced by transfusion. TRALI is the leading cause of transfusion-related death, and is caused by the infusion of either anti-leukocyte antibodies in plasma containing blood products or neutrophil priming substances that accumulate during storage of cellular blood products. Among these neutrophil priming substances are bioactive lipids, such as lyso-phosphatidylcholines (lysoPCs) and arachidonic acid, soluble CD40L (sCD40L) and possibly other, as yet unidentified substances. The accumulation of these substances during cellular blood product storage and their role in the induction of "non-immune mediated" TRALI pathogenesis are highly relevant for the current debate of the use of longer vs. shorter stored blood products. In this review, the accumulation of these different substances during storage, as well as their mode of action in inducing TRALI are discussed. In addition, different improvements in current blood banking procedures to prevent TRALI due to these non-immune mediators will be proposed.

    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.

    Full Text Available Preparation of this publication was motivated by a desire to present contemporary authors look at one of the most important branches of critical care medicine - transfusion therapy and related complications, such as transfusion-related lung injury (TRALI. The article describes the causes, pathogenesis, diagnosis and therapy of TRALI patients in critical condition. In this article attention is paid to the diagnosis of TRALI, associated with transfusion of blood components, modern diagnosis criteria. The authors describe the clinical symptoms, treatment schema and propose prevention protocol of TRALI. In order to determine the incidence of TRALI in medical practice transfusion therapy data in 1900 patients was analyzed. The development of this complication was found in 12 patients, 5 patients had «possible TRALI», which is comparable with the literature data. In 5 patients and 11 donors at a laboratory study anti-leukocyte antibodies were found. The important role of prevention, based on the immune mechanisms of the pathogenesis of TRALI is marked.

    1989-06-01

    An experimental model to simulate acutely raised intracranial pressure due to a rapidly expanding intracranial space-occupying lesion was used to produce neurogenic shock. Forty-one rats in neurogenic shock (defined as a mean systemic arterial pressure (SAP) of less than 60 mm Hg) were subjected to various treatments to increase the mean SAP to a level of more than 80 mm Hg. The control group with neurogenic shock received no treatment, and the six treatment groups received infusions of: whole blood, packed cells, plasma, normal saline, dopamine, or a combination of dopamine and saline. Detrimental effects were observed after transfusion of packed cells or whole blood, which caused further deterioration of mean SAP. Although dopamine or the combination of dopamine and saline were both effective (p = 0.0001) for reversing hypotension, the combination was the most effective. If this rat paradigm correlates with human disease, these results indicate that, in the absence of hypovolemia, neurogenic shock due to acute intracranial hypertension should be treated with a combined transfusion of dopamine and normal saline, but not blood since the latter could have a detrimental effect.

    Platelet transfusion after acute spontaneous primary intracerebral haemorrhage in people taking antiplatelet therapy might reduce death or dependence by reducing the extent of the haemorrhage. We aimed to investigate whether platelet transfusion with standard care, compared with standard care alone, reduced death or dependence after intracerebral haemorrhage associated with antiplatelet therapy use. We did this multicentre, open-label, masked-endpoint, randomised trial at 60 hospitals in the Netherlands, UK, and France. We enrolled adults within 6 h of supratentorial intracerebral haemorrhage symptom onset if they had used antiplatelet therapy for at least 7 days beforehand and had a Glasgow Coma Scale score of at least 8. With use of a secure web-based system that concealed allocation and used biased coin randomisation, study collaborators randomly assigned participants (1:1; stratified by hospital and type of antiplatelet therapy) to receive either standard care or standard care with platelet transfusion within 90 min of diagnostic brain imaging. Participants and local investigators giving interventions were not masked to treatment allocation, but allocation was concealed from outcome assessors and investigators analysing data. The primary outcome was shift towards death or dependence rated on the modified Rankin Scale (mRS) at 3 months, and analysed by ordinal logistic regression, adjusted for stratification variables and the Intracerebral Haemorrhage Score. The primary analysis was done in the intention-to-treat population and safety analyses were done in the intention-to-treat and as-treated populations. This trial is registered with the Netherlands Trial Register, number NTR1303, and is now closed. Between Feb 4, 2009, and Oct 8, 2015, 41 sites enrolled 190 participants. 97 participants were randomly assigned to platelet transfusion and 93 to standard care. The odds of death or dependence at 3 months were higher in the platelet transfusion group than in the

    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.

    Transfusion-related acute lung injury (TRALI) is the leading cause of transfusion-related morbidity and mortality. Both antibodies and bioactive lipids that have accumulated during storage of blood have been implicated in TRALI pathogenesis. In a single-center, nested, case-control study, patients were prospectively observed for onset of TRALI according to the consensus definition. Of 668 patients, 16 patients (2.4%) developed TRALI. Patient-related risk factors for onset of TRALI were age and time on the cardiopulmonary bypass. Transfusion-related risk factors were total amount of blood products (odds ratio [OR] = 1.2; 95% confidence interval [CI], 1.03-1.44), number of red blood cells stored more than 14 days (OR = 1.6; 95% CI, 1.04-2.37), total amount of plasma (OR = 1.2; 95% CI, 1.03-1.44), presence of antibodies in donor plasma (OR = 8.8; 95% CI, 1.8-44), and total amount of transfused bioactive lipids (OR = 1.0; 95% CI, 1.00-1.07). When adjusted for patient risk factors, only the presence of antibodies in the associated blood products remained a risk factor for TRALI (OR = 14.2; 95% CI, 1.5-132). In-hospital mortality of TRALI was 13% compared with 0% and 3% in transfused and nontransfused patients, respectively (P < .05). In conclusion, the incidence of TRALI is high in cardiac surgery patients and associated with adverse outcome. Our results suggest that cardiac surgery patients may benefit from exclusion of blood products containing HLA/HNA antibodies.

    Serious adverse effects of transfusion may be immunologically or non-immunologically mediated. Currently, bacterial contamination of blood products, particularly platelets, is one of the most significant causes of transfusion-related morbidity and mortality. Septic transfusion reactions can present with clinical symptoms similar to immune-mediated hemolytic transfusion reactions and transfusion-related acute lung injury. Extremely high fever and/or gastrointestinal symptoms, in a transfusion recipient, may be indicative of sepsis. The diagnosis is based upon culturing the same organism from both the patient and the transfused blood component. Numerous organisms have been implicated as the cause of septic transfusion reactions. Due to different storage conditions, gram negative organisms are more often isolated from red blood cell components; gram positive organisms are more often isolated from platelets. Prevention of septic transfusion reactions is primarily dependent on an adequate donor history and meticulous preparation of the donor phlebotomy site. Visual inspection of blood components prior to transfusion is also vital to preventing these reactions. Several methods of detection of bacterial contamination and inactivation of pathogens are currently under active investigation.

    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.

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

    Märtlbauer, E.

    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

    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.

    To investigate the color difference between two placental shares in monochorionic placentas with acute peripartum twin-twin transfusion syndrome (TTTS) and twin anemia-polycythemia sequence (TAPS). We evaluated all digital pictures of TAPS, acute peripartum TTTS and a control group of uncomplicated monochorionic placentas examined at our center. We determined the color intensity of the individual placental share on the maternal side of each monochorionic placenta using an image-processing program and calculated the color difference ratio (CDR). Digital pictures of 5 acute peripartum TTTS, 25 TAPS and 54 control group placentas were included in this study. The median CDR in acute peripartum TTTS was significantly lower compared to TAPS placentas, 1.20 (inter-quartile range (IQR) 1.05-1.20) and 2.50 (IQR 1.85-3.34), respectively (p < 0.01), and was comparable to the control group (CDR 1.11, IQR 1.05-1.22). TAPS placentas have a higher CDR compared to acute peripartum TTTS placentas. Examining color difference on the maternal side of the placenta might help distinguish between acute peripartum TTTS and TAPS. Copyright © 2017 Elsevier Ltd. All rights reserved.

    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.

    Blood loss and bleeding complications may often be observed in critically ill patients on renal replacement therapies (RRT). Here we investigate procedural (i.e. RRT-related) and non-procedural blood loss as well as transfusion requirements in regard to the chosen mode of dialysis (i.e. intermittent haemodialysis [IHD] versus continuous veno-venous haemofiltration [CVVH]). Two hundred and fifty-two patients (122 CVVH, 159 male; aged 61.5±13.9 years) with dialysis-dependent acute renal failure were analysed in a sub-analysis of the prospective randomised controlled clinical trial-CONVINT-comparing IHD and CVVH. Bleeding complications including severity of bleeding and RRT-related blood loss were assessed. We observed that 3.6% of patients died related to severe bleeding episodes (between group P=0.94). Major all-cause bleeding complications were observed in 23% IHD versus 26% of CVVH group patients (P=0.95). Under CVVH, the rate of RRT-related blood loss events (57.4% versus 30.4%, P=0.01) and mean total blood volume lost was increased (222.3±291.9 versus 112.5±222.7 ml per patient, P dialysis-dependent acute renal failure in this regard.

  11. Possible mechanisms underlying development of transfusion-related acute lung injury: roles of anti-major histocompatibility complex class II DR antibody.

    2003-06-01

    Anti-major histocompatibility complex (anti-MHC) antibodies (Abs) and antipolymorphonuclear neutrophil (anti-PMN) Abs are generally considered as the main causes of the development of transfusion-related acute lung injury (TRALI), which is one of the most severe and sometimes lethal side effects of transfusion. These Abs are postulated to activate recipient's leucocytes, resulting in the release of soluble factors such as reactive oxygen species and detrimental cytokines and chemokines. The harmful effects on the lung tissues and resident leucocytes of these malignant factors are suspected to be profoundly involved in TRALI reactions. Several reports have indicated the principle effect of biologically active lipids on the pathogenesis of TRALI. However, the precise mechanisms of TRALI development remain unclear. To resolve this issue, we have been investigating cytokines that induce continuous inflammation of the lungs, specifically focusing on the cytokines derived from activated PMNs. We observed that the granulocyte-macrophage colony-stimulating factor (GM-CSF) markedly enhances the expression of MHC class II DR in PMNs. Moreover, MHC class II DR-expressing PMNs were also proved to express a high-affinity receptor for immunoglobulin E (IgE) (FcepsilonRI) and to produce tumour necrosis factor-alpha, interferon-gamma and interleukin-18 following a challenge with an anti-MHC class II DR monoclonal Ab (MoAb) or anti-DR antiserum. It is strongly suggested that amongst various inflammatory mediators, at least these three cytokines may contribute to the duration of inflammatory reactions in the lungs. Furthermore, FcepsilonRI expression, in GM-CSF-treated PMNs, suggests the involvement of PMNs in IgE-mediated immune reactions.

    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).

    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.

  18. Hemolytic Transfusion Reactions

    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.

    Patients with gastrointestinal bleeding often require large volume blood transfusion. Among the various side effects of blood transfusion, the increase of potassium levels is a serious one which is often overlooked. We report a case of severe hyperkalemia in a patient with gastric bleeding after large volume transfusion of packed red blood cells. The patient had hyperkalemia at baseline associated with his receiving medication as well as acute renal failure following hypovolemia. The baseline hyperkalemia was further aggravated after massive transfusions of packed red blood cells in a short period of time. The associated pathogenetic mechanisms resulting in the increase of potassium levels are presented. A number of risk factors which increase the risk of hyperkalemia after blood transfusion are discussed. Moreover, appropriate management strategies for the prevention of blood transfusion associated hyperkalemia are also presented. Physicians should always keep in mind the possibility of hyperkalemia in cases of blood transfusion. PMID:28101452

    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.

    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.

    Recently there have been a number of studies and presentations on the importance of providing a placental transfusion to the newborn. Early cord clamping is an avoidable, unphysiologic intervention that prevents the natural process of placental transfusion. However, placental transfusion, although simple in concept, is affected by multiple factors, is not always straightforward to implement, and can be performed using different methods, making this basic procedure important to discuss. Here, we review three placental transfusion techniques: delayed cord clamping, intact umbilical cord milking and cut-umbilical cord milking, and the evidence in term and preterm newborns supporting this practice. We will also review several factors that influence placental transfusion, and discuss perceived risks versus benefits of this procedure. Finally, we will provide key straightforward concepts and implementation strategies to ensure that placental-to-newborn transfusion can become routine practice at any institution. PMID:27654493

    Frequent allergic reactions following transfusion are observed. Usually, they are benign but sometimes we observe severe allergic reactions. Adverse reactions may be brought about by least two mechanisms. First, immediate-type hypersensibility reactions due to IgE. Secondly, anaphylactic-type reactions due to interaction between transfused IgA and class specific anti IgA in the recipient's plasma. They are characterized by their severest form (anaphylactic shock). The frequency of severe reactions following the transfusion blood plasma is very low. These transfusion reactions are complement-mediated and kinins-mediated. Prevention of allergic reactions is necessary among blood donors and recipients.

    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. METHODS Children of various age groups presenting with clinical profile like symptomatic anaemia, haemolytic anaemia, haematological malignancy, acute sickle cell

    Transfusion-related acute lung injury (TRALI) is a form of posttransfusion acute pulmonary insufficiency that has been linked to the infusion of biologic response modifiers (BRMs), including antileukocyte antibodies and lipids. Soluble CD40 ligand (sCD40L) is a platelet-derived proinflammatory mediator that accumulates during platelet storage. We hypothesized that human polymorpho-nuclear leukocytes (PMNs) express CD40, CD40 ligation rapidly primes PMNs, and sCD40L induces PMN-mediated cytotoxicity of human pulmonary microvascular endothelial cells (HMVECs). Levels of sCD40L were measured in blood components and in platelet concentrates (PCs) implicated in TRALI or control PCs that did not elicit a transfusion reaction. All blood components contained higher levels of sCD40L than fresh plasma, with apheresis PCs evidencing the highest concentration of sCD40L followed by PCs from whole blood, whole blood, and packed red blood cells (PRBCs). PCs implicated in TRALI reactions contained significantly higher sCD40L levels than control PCs. PMNs express functional CD40 on the plasma membrane, and recombinant sCD40L (10 ng/mL-1 μg/mL) rapidly (5 minutes) primed the PMN oxidase. Soluble CD40L promoted PMN-mediated cytotoxicity of HMVECs as the second event in a 2-event in vitro model of TRALI. We concluded that sCD40L, which accumulates during blood component storage, has the capacity to activate adherent PMNs, causing endothelial damage and possibly TRALI in predisposed patients.

    Introduction Acquired haemophilia is a rare autoimmune disorder caused by autoantibodies directed in the majority of the cases against clotting factor VIII. This disorder is characterised by the sudden onset of bleeding that not rarely may be life-threatening and need transfusion support. Most reports on this condition describe the need for blood transfusions during the acute, haemorrhagic phase, but the number of transfused red cell units is often unknown. Patients and methods In the last 5 years, 14 patients with acquired haemophilia A were identified in the transfusion and haemophilia centres of Verona and Castelfranco Veneto. The transfusion support for these 14 patients was analyzed in this retrospective survey. Results The 14 patients required a total of 183 red cell units. The average transfusion requirement was 13 red cells units/patient, with a range from 0 to 38 units. Conclusions Eleven of the 14 patients studied needed strong transfusion support to enable any further management of the haemorrhages, as well as for eradication treatment of the autoantibodies to factor VIII. A relevant part of the management of haemorrhagic symptoms as well as the first choice for any further treatment (bleeding or the cure of the underlying disease) is transfusion of red blood cells.

    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.

  20. Alloimmune refractoriness to platelet transfusions.

    Science.gov (United States)

    Sandler, S G

    1997-11-01

    Patients who are transfused on multiple occasions with red cells or platelets may develop platelet-reactive alloantibodies and experience decreased clinical responsiveness to platelet transfusion. This situation, conventionally described as "refractoriness to platelet transfusions," is defined by an unsatisfactory low post-transfusion platelet count increment. If antibodies to HLAs are detected, improved clinical outcomes may result from transfusions of HLA-matched or donor-recipient cross-matched platelets. Because refractoriness is an expected, frequently occurring phenomenon, prevention of HLA alloimmunization is an important management strategy. Prevention strategies include efforts to decrease the number of transfusions, filtration of cellular components to reduce the number of HLA-bearing leukocytes, or pretransfusion ultraviolet B irradiation of cellular components to decrease their immunogenicity. Other investigational approaches include reducing the expression of HLAs on transfused platelets, inducing a transient reticuloendothelial system blockade by infusions of specialized immunoglobulin products, or transfusing semisynthetic platelet substitutes (thromboerythrocytes, thrombospheres) or modified platelets (infusible platelet membranes, lyophilized platelets).

    Care of the patient with massive bleeding involves more than aggressive surgery and infusion of large amounts of blood products. The proper management of massive transfusions-whether they are in trauma patients or other bleeding patients-requires coordination of the personnel in the surgical suite or the emergency department, the blood bank, and laboratory.

    We estimated rates for common plasma-associated transfusion reactions and compared reported rates for various plasma types. We performed a systematic review and meta-analysis of peer-reviewed articles that reported plasma transfusion reaction rates. Random-effects pooled rates were calculated and compared between plasma types. Meta-regression was used to compare various plasma types with regard to their reported plasma transfusion reaction rates. Forty-eight studies reported transfusion reaction rates for fresh-frozen plasma (FFP; mixed-sex and male-only), amotosalen INTERCEPT FFP, methylene blue-treated FFP, and solvent/detergent-treated pooled plasma. Random-effects pooled average rates for FFP were: allergic reactions, 92/10(5) units transfused (95% confidence interval [CI], 46-184/10(5) units transfused); febrile nonhemolytic transfusion reactions (FNHTRs), 12/10(5) units transfused (95% CI, 7-22/10(5) units transfused); transfusion-associated circulatory overload (TACO), 6/10(5) units transfused (95% CI, 1-30/10(5) units transfused); transfusion-related acute lung injury (TRALI), 1.8/10(5) units transfused (95% CI, 1.2-2.7/10(5) units transfused); and anaphylactic reactions, 0.8/10(5) units transfused (95% CI, 0-45.7/10(5) units transfused). Risk differences between plasma types were not significant for allergic reactions, TACO, or anaphylactic reactions. Methylene blue-treated FFP led to fewer FNHTRs than FFP (risk difference = -15.3 FNHTRs/10(5) units transfused; 95% CI, -24.7 to -7.1 reactions/10(5) units transfused); and male-only FFP led to fewer cases of TRALI than mixed-sex FFP (risk difference = -0.74 TRALI/10(5) units transfused; 95% CI, -2.42 to -0.42 injuries/10(5) units transfused). Meta-regression demonstrates that the rate of FNHTRs is lower for methylene blue-treated compared with FFP, and the rate of TRALI is lower for male-only than for mixed-sex FFP; whereas no significant differences are observed between plasma types for allergic

    level lower than 10 g/dL was found in 33% on admission in the ICU. A total of 348 RBC units were transfused in 86 patients (36.5%. The mean pretransfusion hemoglobin level was 7.7 ± 1.1 g/dL. Transfused-patients had significantly higher SOFA score (7.9 ± 4.6 vs 5.6 ± 3.8, p < 0.05, respectively, days on mechanical ventilation (10.7 ± 8.2 vs 7.2 ± 6.4, p < 0.05 and days on vasoactive drugs (6.7 ± 6.4 vs 4.2 ± 4.0, p < 0.05 than non-transfused patients despite similar APACHE II scores (15.2 ± 8.1 vs 14.2 ± 8.1, NS. Transfused patients had higher mortality rate (43.5% than non-transfused patients (36.3% (RR 0.60-1.15, NS. Only one patient (0.28% had febrile non-hemolytic transfusion and urticarial reactions. CONCLUSIONS: Anemia is common in critically ill patients.It seems from the present study that transfusion practices in Brazil have had a more restrictive approach with a lower limit "transfusion trigger".

    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.

    Transfusion medicine research has traditionally employed quantitative methods to answer clinical research questions. Increasingly, qualitative research methods are being used in the field to address a wide variety of research questions in areas such as blood donation, transfusion practices and policy development. This article describes the key characteristics, methodologies and methods of qualitative research and draws on examples to show how qualitative research approaches have been applied in the field of transfusion medicine. It is hoped that this overview will inform and encourage the application of qualitative research in the field of transfusion medicine.

  16. Red blood cell transfusion in preterm neonates: current perspectives

    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

    Severe transfusion reactions occur much less often than minor reactions, but it is difficult to discriminate clinically between impending severe reactions and minor reactions. Therefore, whenever a reaction occurs, the transfusion should be discontinued and a laboratory workup initiated to rule out an acute hemolytic transfusion reaction. At a minimum, a direct antiglobulin (Coombs') test should be performed, and specimens obtained before and after transfusion should be assayed for hemoglobinemia and hemoglobinuria. If the product transfused included red blood cells, then typing and crossmatching should be repeated on a posttransfusion blood specimen. Routine premedication with antipyretics is not recommended, since they may mask early signs and symptoms of more severe reactions and their efficacy is questionable. Recent insights into the mechanisms of transfusion reactions have suggested interventions that may help minimize or prevent potentially serious sequelae.

    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.

    Red blood cells (RBCs) units are the most requested transfusion product worldwide. Indications for transfusion include symptomatic anaemia, acute sickle cell crisis, and acute blood loss of more than 30% of the blood volume, with the aim of restoring tissue oxygen delivery. However, stored RBCs from donors are not a qualitative equal product, and, in many ways, this is a matter of concern in the transfusion practice. Besides donor-to-donor variation, the storage time influences the RBC unit at the qualitative level, as RBCs age in the storage bag and are exposed to the so-called storage lesion. Several studies have shown that the storage lesion leads to post-transfusion enhanced clearance, plasma transferrin saturation, nitric oxide scavenging and/or immunomodulation with potential unwanted transfusion-related clinical outcomes, such as acute lung injury or higher mortality rate. While, to date, several studies have claimed the risk or deleterious effects of “old” vs “young” RBC transfusion regimes, it is still a matter of debate, and consideration should be taken of the clinical context. Transfusion-dependent patients may benefit from transfusion with “young” RBC units, as it assures longer inter-transfusion periods, while transfusion with “old” RBC units is not itself harmful. Unbiased Omics approaches are being applied to the characterisation of RBC through storage, to better understand the (patho)physiological role of microparticles (MPs) that are found naturally, and also on stored RBC units. Perhaps RBC storage time is not an accurate surrogate for RBC quality and there is a need to establish which parameters do indeed reflect optimal efficacy and safety. A better Omics characterisation of components of “young” and “old” RBC units, including MPs, donor and recipient, might lead to the development of new therapies, including the use of engineered RBCs or MPs as cell-based drug delivering tools, or cost-effective personalised transfusion

    Post-transfusion reactions with dyspnoea (PTR) are major causes of morbidity and death after blood transfusion. Transfusion-related acute lung injury (TRALI) and transfusion-associated circulatory overload (TACO) are most dangerous, while transfusion-associated dyspnoea (TAD) is a milder respiratory distress. We investigated blood components for immune and non-immune factors implicated in PTR. We analysed 464 blood components (RBCs, PLTs, L-PLTs, FFP) transfused to 271 patients with PTR. Blood components were evaluated for 1/antileucocyte antibodies, 2/cytokines: IL-1β, IL-6, IL-8, TNF-α, sCD40L, 3/lysophosphatidylcholines (LysoPCs), 4/microparticles (MPs) shed from plateletes (PMPs), erythrocytes (EMPs) and leucocytes (LMPs). Anti-HLA class I/II antibodies or granulocyte-reactive anti-HLA antibodies were detected in 18.2% of blood components (RBC and FFP) transfused to TRALI and in 0.5% of FFP transfused to TAD cases. Cytokines and LysoPCs concentrations in blood components transfused to PTR patients did not exceed those in blood components transfused to patients with no PTR. Only EMPs percentage in RBCs transfused to patients with TRALI was significantly higher (P Blood Transfusion.

    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.

    2016-03-01

    Massive transfusion practices were transformed during the 1970s without solid evidence supporting the use of component therapy. A manual literature search was performed for all references to the lethal triad, acute or early coagulopathy of trauma, fresh whole blood, and component transfusion therapy in massive trauma, and damage control resuscitation. Data from recent wars suggest traditional component therapy causes a nonhemostatic resuscitation worsening the propagation of the lethal triad hastening death. These same studies also indicate the advantage of fresh whole blood over component therapy even when administered in a 1:1:1 replacement ratio.

    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.

    Full Text Available Graham R Serjeant Sickle Cell Trust (Jamaica, Kingston, Jamaica Abstract: Homozygous sickle cell (SS disease is associated with rapid red cell destruction and a tendency to block flow in blood vessels. The bone marrow expansion needed to compensate for the rapid red cell destruction increases metabolic demands and folate requirements but also renders the bone marrow prone to suppression by renal impairment and infections especially those with human parvovirus B19. The abnormal red cells also tend to block blood vessels impairing flow in the bone marrow (dactylitis, bone pain crisis, hip necrosis, the spleen (acute splenic sequestration, chronic hypersplenism, loss of the normal filtering system rendering patients prone to overwhelming septicemia, the lungs (pulmonary embolism, acute chest syndrome, and the brain (ischemic stroke, hemorrhage. Transfusion plays a role in addressing all of these pathologies. During the acute lowering of hemoglobin due to acute splenic sequestration and aplastic crisis and the persistent lowering of hemoglobin due to chronic hypersplenism and chronic renal failure, top-up transfusions may help in maintaining oxygen delivery and symptomatic relief. Addressing vaso-occlusion is more complex but best documented in preventing recurrent stroke and primary stroke following detection of cerebral vessel stenosis by transcranial Doppler. Although top-up transfusions have minimal side effects, potentially serious complications arise from chronic transfusion, and there are many unanswered questions on the duration of such therapy and the natural history of the underlying complications. These issues are addressed with the knowledge currently available. Keywords: sickle hemoglobin, HbS, transfusion, oxygen affinity, anemia, vaso-occlusion

    Transfusion-transmitted Chagas' disease has been recognized since 1952. Until recently, no cases were reported outside of Latin America. However, emigration during the past 20 years expanded its transfusional geographic borders to North America. Trypanosoma cruzi-infected donors usually are asymptomatic, often for a lifetime. This situation complicates donor screening, particularly in regions where blood bank personnel are not familiar with the risk factors and natural history of this transfusion-transmitted infection. This review addresses the main aspects of epidemiology, risks of infection, clinical symptoms in donors and recipients, preventive measures, and blood donor screening to prevent transfusion-transmitted Chagas' disease.

    The cost and risks of red blood cell (RBC) transfusions, along with evidence of overuse, suggest that improving transfusion practices is a key opportunity for health systems to improve both the quality and value of patient care. Previous work, which included a BestPractice Advisory (BPA), was adapted in a quality improvement project designed to reduce both exposure to unnecessary blood products and costs. A prospective, pre-post study was conducted at an academic medical center with a diverse patient population. All noninfant inpatients without gastrointestinal bleeding who were not within 12 hours of surgical procedures were included. The interventions were education, a BPA, and other enhancements to the computerized provider order entry system. The percentage of multiunit (≥ 2 units) RBC transfusions decreased from 59.9% to 41.7% during the intervention period and to 19.7% postintervention (p < 0.0001). The percentage of inpatient RBC transfusion units administered for hemoglobin (Hb) ≥ 7 g/dL declined from 72.3% to 57.8% during the intervention period and to 38.0% for the postintervention period (p < 0.0001). The overall rate of inpatient RBC transfusion (units administered per 1,000 patient-days without exclusions) decreased from 89.8 to 78.1 during the intervention period and to 72.7 during the postintervention period (p <0.0001). The estimated annual cost savings was $1,050,750. The interventions reduced multiunit transfusions (by 67.1%) and transfusions for Hb ≥ 7 g/dL (by 47.4%). The improvement in the overall transfusion rate (19.0%) was less marked, limited by better baseline performance relative to other centers. Copyright © 2017 The Joint Commission.

    of modern trauma care are targeted to the early correction of acute traumatic coagulopathy. The aim of this study was to identify a clinically relevant definition of trauma massive transfusion based on clinical outcomes. We also examined whether the concept was useful in that early prediction of massive...... transfusion requirements could allow early activation of blood bank protocols. METHODS : Datasets on trauma admissions over a 1 or 2-year period were obtained from the trauma registries of five large trauma research networks. A fractional polynomial was used to model the transfusion-associated probability...... moderate performance. The area under the receiver operating characteristic curve was 0.81, with specificity of only 50% at a sensitivity of 90% for the prediction of 10 or more PRBC units. Performance varied widely at different trauma centers, with specificity varying from 48% to 91%. CONCLUSIONS...

    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.

    Benchmarking is as a structured continuous collaborative process in which comparisons for selected indicators are used to identify factors that, when implemented, will improve transfusion practices. This study aimed to identify transfusion medicine studies reporting on benchmarking, summarize the benchmarking approaches used, and identify important considerations to move the concept of benchmarking forward in the field of transfusion medicine. A systematic review of published literature was performed to identify transfusion medicine-related studies that compared at least 2 separate institutions or regions with the intention of benchmarking focusing on 4 areas: blood utilization, safety, operational aspects, and blood donation. Forty-five studies were included: blood utilization (n = 35), safety (n = 5), operational aspects of transfusion medicine (n = 5), and blood donation (n = 0). Based on predefined criteria, 7 publications were classified as benchmarking, 2 as trending, and 36 as single-event studies. Three models of benchmarking are described: (1) a regional benchmarking program that collects and links relevant data from existing electronic sources, (2) a sentinel site model where data from a limited number of sites are collected, and (3) an institutional-initiated model where a site identifies indicators of interest and approaches other institutions. Benchmarking approaches are needed in the field of transfusion medicine. Major challenges include defining best practices and developing cost-effective methods of data collection. For those interested in initiating a benchmarking program, the sentinel site model may be most effective and sustainable as a starting point, although the regional model would be the ideal goal.

    Blood component transfusion may be required in association with emergency and chronic disease to improve hemodynamics and tissue oxygenation. Due to the risk of microbial transfection from donor to recipient, the blood is undergoing vigorous testing to improve safety. It is well known, however......, that blood component transfusion may lead to certain acute side effects with a frequency of 0.5-2% depending on the specific component transfused. In addition, homologous blood component transfusion seems to be associated with increased frequency of bacterial infectious complication after operation...... in a variety of diseases. If patients have been operated on for malignant diseases, emerging evidence has accumulated that suggests a combination of blood component transfusion, postoperative bacterial infectious complications and subsequent poor longterm survival even in patients who have been curatively...

    Blood passport has been suggested as an indirect tool to detect various kinds of blood manipulations. Autologous blood transfusions are currently undetectable, and the objective of this study was to examine the sensitivities of different blood markers and blood passport approaches in order 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 can be an acute practice with blood withdrawal and reinfusion within a few days, Hbmass seems to be the only option for revealing this practice. © 2009 John Wiley & Sons A/S.

    A blood transfusion is an acute intervention, used to address life- and health-threatening conditions on a short-term basis. Packed red blood cells are most often used for blood transfusion. Sometimes blood is transfused after prolonged storage but there is continuing debate as to whether transfusion of 'older' blood is as beneficial as transfusion of 'fresher' blood. To assess the clinical benefits and harms of prolonged storage of packed red blood cells, in comparison with fresh, on recipients of blood transfusion. We ran the search on 1st May 2014. We searched the Cochrane Injuries Group Specialized Register, Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library), MEDLINE (OvidSP), Embase (OvidSP), CINAHL (EBSCO Host) and two other databases. We also searched clinical trials registers and screened reference lists of the retrieved publications and reviews. We updated this search in June 2015 but these results have not yet been incorporated. Randomised clinical trials including participants assessed as requiring red blood cell transfusion were eligible for inclusion. Prolonged storage was defined as red blood cells stored for ≥ 21 days in a blood bank. We did not apply limits regarding the duration of follow-up, or country where the study took place. We excluded trials where patients received a combination of short- and long-stored blood products, and also trials without a clear definition of prolonged storage. We independently performed study selection, risk of bias assessment and data extraction by at least two review authors. The major outcomes were death from any cause, transfusion-related acute lung injury, and adverse events. We estimated relative risk for dichotomous outcomes. We measured statistical heterogeneity using I(2). We used a random-effects model to synthesise the findings. We identified three randomised clinical trials, involving a total of 120 participants, comparing packed red blood cells with ≥ 21 days storage

    Non-transfusion-dependent thalassemias include a variety of phenotypes that, unlike patients with beta (β)-thalassemia major, do not require regular transfusion therapy for survival. The most commonly investigated forms are β-thalassemia intermedia, hemoglobin E/β-thalassemia, and α-thalassemia intermedia (hemoglobin H disease). However, transfusion-independence in such patients is not without side effects. Ineffective erythropoiesis and peripheral hemolysis, the hallmarks of disease process, lead to a variety of subsequent pathophysiologies including iron overload and hypercoagulability that ultimately lead to a number of serious clinical morbidities. Thus, prompt and accurate diagnosis of non-transfusion-dependent thalassemia is essential to ensure early intervention. Although several management options are currently available, the need to develop more novel therapeutics is justified by recent advances in our understanding of the mechanisms of disease. Such efforts require wide international collaboration, especially since non-transfusion-dependent thalassemias are no longer bound to low- and middle-income countries but have spread to large multiethnic cities in Europe and the Americas due to continued migration.

    Results: A total of 411 pediatric and 433 surgical patients received 594 and 745 transfusions respectively during the study period. Of these, TRs were observed in 69 (11.6% children and 63 (8.4% surgical patients. Majority of reactions in children (48, 69.5% and surgical patients (51, 80.9% were acute, developing within 24 h of transfusion. TRs were observed with packed cells (13.2%, cryoprecipitate (10%, platelet concentrate (14.3% and fresh frozen plasma (1.3% in pediatric patients and with packed cells (7.2%, whole blood (25% and platelet concentrate (62.5% in surgical patients. Most common TRs included febrile nonhemolytic TRs (FNHTRs and allergic reactions. Reactions were more frequent in patients with a previous history of transfusion or those receiving more than one transfusion and in children, when transfusion was initiated after 30 min of issue of blood component. Majority of reactions were managed with symptomatic treatment, were nonserious, moderately severe, probably preventable and probably associated with the suspect blood component in both populations. Conclusion: Transfusion reactions in children and surgical patients are commonly observed with cellular blood components. Majority of reactions are acute and nonserious. FNHTRs and allergic reactions are the most common transfusion reactions. Risk of transfusion reactions is more in patients receiving multiple transfusions.

    Full Text Available Sepsis is a clinical syndrome characterised by systemic inflammation due to infection. There is a spectrum with severity ranging from sepsis to severe sepsis and septic shock. Even with optimal treatment, mortality due to severe sepsis or septic shock is significant and poses a challenge to management. Antibiotics, source control, resuscitation with fluids, vasopressor and inotropic agents are the main-stay of treatment for septic shock. These may be supplemented with transfusion of red blood cells and or blood products, in the case of anaemia to sustain sufficient oxygen delivery [1] or to manage associated haematological issues. Transfusion in sepsis has always been a debatable issue, especially in relation to choice of the fluid and the role of blood or blood product transfusion.

    Full Text Available Introduction. 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.

    Complications after blood components still constitute an important clinical problem and serve as limitation of liberal-transfusion strategy. The aim of the study was to present the 5-year incidence of early blood transfusions complications and to assess their relation to the type of the transfused blood components. 58,505 transfusions of blood components performed in the years 2006-2010 were retrospectively analyzed. Data concerning the amount of the transfused blood components and the numbers of adverse transfusion reactions reported to the Regional Blood Donation and Treatment Center (RBDTC) was collected. 95 adverse transfusion reactions were reportedto RBDTC 0.16% of alldonations (95/58 505) - 58 after PRBC transfusions, 28 after platelet concentrate transfusions and 9 after FFP transfusion. Febrile nonhemolytic and allergic reactions constitute respectively 36.8% and 30.5% of all complications. Nonhemolyticand allergic reactions are the most common complications of blood components transfusion and they are more common after platelet concentrate transfusions in comparison to PRBC and FFP donations.

  10. Best practices for transfusion for patients with sickle cell disease

    2010-01-01

    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.

  11. Transfusion-associated circulatory overload in adult, medical emergency patients with perspectives on early warning practice: a single-centre, clinical study.

    Transfusion-associated circulatory overload is characterised by acute respiratory distress, tachycardia, increased blood pressure, acute pulmonary oedema and/or evidence of positive fluid balance occurring within 6 hours after transfusion. Transfusion-associated circulatory overload is a serious, underreported reaction, which makes this iatrogenic condition difficult to prevent. We present an audit of patients admitted to a medical emergency unit, aiming to investigate: (i) the incidence of transfusion-associated circulatory overload; and (ii) whether cases were reported to the haemovigilance system. The clinical implications are discussed within the frame of the Early Warning Score. We conducted a retrospective audit of electronic hospital medical records of patients receiving blood transfusion in a single medical emergency unit. Patients were admitted during a 6-month period and data on symptoms and vital signs were extracted from the records. Of 4,353 consecutively admitted patients, 156 patients were transfused with a total of 411 blood components. The audit identified five cases of transfusion-associated circulatory overload (incidence 3.2%) and four cases of transfusion-associated dyspnoea. Vital signs and changes in dyspnoea and blood pressure were registered within the frame of the Early Warning Score, and one case was documented as being transfusion-related in the medical record. No cases were reported to the haemovigilance system. The incidence of transfusion-associated circulatory overload in acute emergency patients was similar to that in other clinical studies. Lack of recognition and reporting was marked, even though changes in vital signs were monitored in the context of the Early Warning Score. This study points to a missing link in the transfusion chain, namely recognising the vital signs of circulatory overload during or shortly after transfusion as being a serious adverse transfusion reaction.

    The aim of the study was to document transfusion practices in a cross section of general intensive care units (ICUs) in Israel and to determine whether current guidelines are being applied. This prospective study was performed in 5 general ICUs in Israel over a 3-month period. Red cell transfusion data collected on consecutive patients included the trigger, units transfused per transfusion event, and indications, categorized either to treat a specified condition for which transfusions may be beneficial (acute hemorrhage, acute myocardial ischemia, or severe sepsis) or to treat a low hemoglobin concentration. Of the 238 patients studied, 50% received at least one red blood cell transfusion. The main indication for transfusion (43.7%, or 162/368 U transfused) was to treat a low hemoglobin concentration, in the absence of one of the specified conditions. Total red cell use was 3.0 ± 2.9 U per admission, and patients received a mean of 1.2 ± 0.4 U per transfusion event. The transfusion trigger for the whole group was 7.9 ± 1.1 g/dL. This did not differ significantly between the indications apart from a significantly higher trigger for patients with acute myocardial ischemia (8.8 ± 0.9 g/dL). In addition, patients with a history of heart disease had a higher trigger irrespective of the primary indication for transfusion and received significantly more units per transfusion event. Patients receiving a transfusion had significantly longer ICU stay and hospital mortality. Our study showed that evidence-practice gaps continue to exist, and it appears that physician behavior is mainly driven by the absolute level of hemoglobin. Educational interventions focused on these factors are required to limit the widespread and often unnecessary use of this scarce and potentially harmful resource. Copyright © 2011 Elsevier Inc.

    Pre-operative red blood cell (RBC) transfusions are often recommended for patients with sickle cell disease (SCD) who require elective surgery under general anesthesia. However, definitive randomized studies demonstrating the benefit of transfusions in this setting have not been conducted. In particular, the merits of transfusion prior to minor or low-risk surgical procedures in children with SCD have not been demonstrated. We hypothesized that children with sickle cell anemia (Hb SS) who have minor elective surgical procedures develop few complications even without pre-operative transfusion. We accessed our Comprehensive Sickle Cell Program's Database to identify all such procedures performed during a 13-year period. Medical records were reviewed to characterize the surgical procedure, the use of transfusions, and perioperative complications. Twenty-eight children with Hb SS had a total of 38 minor surgical procedures. No perioperative transfusions were given in 34 of the cases (85%). Five of these 34 surgeries (15%) were associated with minor post-operative complications (fever or transient pain). No post-operative acute chest syndrome was encountered. Minor or low-risk elective surgical procedures in children with Hb SS may not routinely require pre-operative transfusion. A randomized clinical trial to compare transfusion with no transfusion for minor surgical procedures is needed.

  15. Transfusion-transmitted parasitic infections

    Full Text Available 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.

    Much of the recent work in transfusion practice has shifted to focus on the patient, after efforts over previous decades to ensure the quality and safety of blood products. After the commencement of hemovigilance and transfusion practice improvement programs, the introduction of transfusion practitioners (TP) into health care services and blood centers has continued to increase worldwide. Since this relatively new role was introduced, much work of the TP has focused on patient and staff education, adverse events, transfusion governance, and monitoring of transfusion practices within organizations. The complex nature of the transfusion process makes the TP an integral link in the transfusion chain. Together with hospital transfusion teams and committees, the TP works collaboratively to facilitate the transfusion change management programs and initiatives. Recently, the TP role has evolved to include an emphasis on patient blood management and, to some extent, is shaped by national standards and regulations. These established roles of the TP, together with the ever-changing field of transfusion medicine, provide new opportunities and challenges for a role that is continuing to evolve worldwide.

    2015-02-01

    Each year, more than three millions of blood components are transfused to more than five hundred thousand patients in France. The optimal use of blood components requires that physicians prescribing blood components master the clinical indications of red blood cells concentrates, platelet concentrates and fresh frozen plasma. In addition, physicians in charge of blood component prescription should provide adequate pre- and post-transfusion information to their patients. Compliance of blood components administration in patients with safety guidelines contributes as well to their optimal use. In addition, for each blood component transfused, a proper evaluation of its safety and its efficacy should be done. Finally, a regular evaluation of transfusion practice in hospital services were blood components are used, through audits made in cooperation with their blood component provider, either blood transfusion centre or the hospital blood bank, enables to appreciate the level of compliance with safety and clinical guidelines, and more globally how the transfusion process is mastered.

    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.

    Sickle cell disease (SCD) patients are at increased risk of red blood cell (RBC) alloimmunization. Recipient inflammatory state at time of transfusion has been shown to regulate alloimmunization in murine models, but evidence is lacking in SCD patients. We retrospectively studied a cohort of alloimmunized SCD patients to determine the influence of pro-inflammatory SCD-related complications at time of transfusion on alloimmunization. For each transfusion, the presence of pro-inflammatory state, degree of RBC antigen matching, unit age, storage solution and alloantibody detection date were ascertained. Transfusion-associated pro-inflammatory events were compared between transfusions resulting and not resulting in new alloantibodies. Univariate analysis and multivariate logistic regression were performed. Fifty-two patients received 3166 pre-storage leuco-reduced transfusions of which 128 resulted in alloantibodies. Transfusions during inflammatory events were associated with increased alloantibody risk on univariate and multivariate analysis; acute chest syndrome and vaso-occlusive crisis showed strongest associations with alloimmunization. Increased antigen matching demonstrated a protective effect on alloimmunization (univariate and multivariate analysis). Although an association was seen between citrate-phosphate-dextrose (adenine) stored units and alloimmunization on univariate analysis, no effect was found on multivariate analysis. Identifying recipient pro-inflammatory states at time of transfusion that promote alloimmunization can impact RBC unit selection decisions for SCD patients at risk for alloimmunization.

  2. Pathophysiology of hemolytic transfusion reactions.

    2005-07-01

    Hemolytic transfusion reactions (HTR) are systemic reactions provoked by immunologic red blood cell (RBC) incompatibility. Clinical and experimental observations of such reactions indicate that they proceed through phases of humoral immune reaction, activation of phagocytes, productions of cytokine mediators, and wide-ranging cellular responses. HTR have many features in common with the systemic inflammatory response syndrome (SIRS). Knowledge of the pathophysiologic mechanisms in HTR suggest that newer biological agents that target complement intermediates or proinflammatory cytokines may be effective agents in the treatment of severe HTRs.

    Neonatal hemochromatosis is a rare congenital disorder of the liver associated to a poor prognosis. Liver transplantation is often required, since no effective medical treatment has been found. Despite mounting evidence of an alloimmune etiology of this condition, exchange transfusion has never been proposed as a specific treatment for neonatal hemochromatosis. Here we describe two siblings affected by neonatal hemochromatosis. The first, a female, died at 18 days of severe coagulopathy and acute renal failure, diagnosed as affected by neonatal hemochromatosis only when the second sibling was suspected as being affected by the same disease. The second child showed a rapidly worsening coagulopathy which was treated with two exchange transfusions, followed by rapid clinical and laboratory improvement, before reaching a definite diagnosis of neonatal hemochromatosis. He is healthy at present after a follow-up of 12 months. Although exchange transfusion has never been considered as treatment for neonatal hemochromatosis, this case suggests that it could be a feasible treatment option for children affected by this disease, as for other alloimmune conditions.

    Abstract The mortality rate caused by organophosphate (OP) poisoning is still high, even the standard treatment such as atropine and oxime improves a lot. To search for alternative therapies, this study was aimed to investigate the effects of packed red blood cell (RBC) transfusion in acute OP poisoning, and compare the therapeutic effects of RBCs at different storage times. Patients diagnosed with OP poisoning were included in this prospective study. Fresh RBCs (packed RBCs stored less than 10 days) and longer-storage RBCs (stored more than 10 days but less than 35 days) were randomly transfused or not into OP poisoning patients. Cholinesterase (ChE) levels in blood, atropine usage and durations, pralidoxime durations were measured. We found that both fresh and longer-storage RBCs (200–400 mL) significantly increased blood ChE levels 6 hours after transfusion, shortened the duration for ChE recovery and length of hospital stay, and reduced the usage of atropine and pralidoxime. In addition, fresh RBCs demonstrated stronger therapeutic effects than longer-storage RBCs. Packed RBCs might be an alternative approach in patients with OP poisoning, especially during early stages.

    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.

    As transfusion is a commonly identified overused intervention, there is a clear gap between evidence-based and clinical practice. To close this gap, there is not only a need for increased transfusion medicine educational opportunities but for those using structured and proven instructional methods. Kern and colleagues have defined important steps to be considered in curricular design: general needs assessment; targeted needs assessment; goals and objectives; educational strategies; implementation; and evaluation and feedback. We use this framework to examine the current state of transfusion medicine educational initiatives for the non-transfusion medicine physician. © 2017 International Society of Blood Transfusion.

    Jehovah's Witness refuse blood transfusion, but they accept organ transplantation, albumin, immunoglobulin, vaccines and clotting factors. We present 3 kidney transplants in Jehovah's Witness patients (two male and one female) without blood transfusion, with a mean age of 31.33 years and a mean body mass index of 20.99 kg/m(2). All patients underwent pretransplant peritoneal dialysis for an average of 52.3 months. Two transplants came from living donors and one from a deceased donor with a cold ischemia of 23 hours. The donors were two females and one male, with a mean age of 34.33 years. All patients received pretransplant erythropoietin and iron dextran and an intraoperative cell saver was used. Hemoglobin, hematocrit, red blood cells and serum creatinine levels, as well as the glomerular filtration at 24 months postransplant were stable. All patients received induction with basiliximab and initial immunosuppression with calcineurin inhibitors. One of the patients had a perirenal hematoma as a complication, which required a surgery 20 days post-transplant. At 5, 26 and 36 months postransplant the three patients are alive and with functional grafts. It is possible to perform kidney transplantation without transfusion in Jehovah's Witness, obtaining an acceptable global survival without acute rejection.

    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.

    Obstetricians and Gynecologists care for many patients with conditions potentially requiring blood transfusions. Cesarean section and hysterectomy are the two surgeries performed most frequently and both have the potential for blood loss requiring transfusion. Other examples include postpartum hemorrhage, placenta previa, and ruptured ectopic pregnancy. Obstetricians and gynecologists need to become knowledgeable about the ever-changing aspects of blood transfusion and apply it in their clinical practice. This review intends to update obstetricians and gynecologists and other health care professionals about the basic as well as the latest technologies of blood transfusion. The different types of blood components are discussed including their preparation, indications, risks, and benefits. The complications of blood transfusion and their management are reviewed, including infections, noninfectious, and immunological etiologies. HIV and hepatitis are explored, these being the most serious infectious risks of transfusion. Autologous blood transfusion, an underutilized option, is examined. Hemodilution and intraoperative blood salvage, other techniques for using the patient's own blood, are discussed. Finally, synthetic agents such as erythropoietin, granulocyte colony-stimulating factors, factors, desmopressin acetate, gonadotropin-releasing hormone agonists, and new products are introduced as potential replacements to blood transfusion in the future.

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

    Full Text Available Çiğdem Akalın Akkök,1,21Department of Immunology and Transfusion Medicine, Oslo University Hospital, Ullevaal, Oslo, Norway; 2Department of Clinical Immunology and Transfusion Medicine, Lund University Hospital, Lund, Sweden Abstract: Allogeneic hematopoietic stem cell transplantation (AHSCT is an intention-to-cure treatment strategy in several malignancies and nonmalignancies. The number of patients receiving AHSCT is increasing due to new indications, and more elderly patients with comorbidities are included in the protocols. Survival of the patients undergoing AHSCT has improved owing to better patient care, including optimization of transfusion support, which has a major contribution. However, transfusion can also be hazardous. Increasing awareness about transfusion and finding the balance between avoiding unnecessary transfusions and transfusing the correct component when needed are the key issues. Myeloablative conditioning results in pancytopenia, and the patients are prone to infections, anemia, and bleeding both before and after transplantation. Until red cell and platelet engraftment, the patients are usually transfusion dependent needing red cell and/or platelet components. Physicians dealing with AHSCT patients should be well informed about the attributes of the blood components they order. Knowledge about transfusion indications, triggers, and how to prevent and manage eventual transfusion complications is also required. The clinical picture can be challenging, and transplantation/treatment-related toxicity/complications can sometimes be difficult to distinguish from a transfusion complication, especially if the latter one took place, for instance, several days or weeks ago. ABO compatibility between the patient and the donor is not a prerequisite when choosing human leukocyte antigen-matched hematopoietic stem cell donor. Consequently, ABO incompatibility exists in ~40% of the cases and brings some immunohematological issues

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. Using the HT care map as a frame of reference along with its associated rites, we examine the contemporary spectrum of HT adverse events and concerns, and some approaches as to how these may be addressed from bedside and laboratory medicine biovigilance perspectives enhancing patient care and blood transfusion safety. Although our vantage point is from an academic community hospital venue, the issues and concerns identified are germane to many if not all transfusion-medicine practice environments. Included among the subjects we explore are patient/specimen identification issues, blood-management initiatives, unrecognized and/or unreported suspected transfusion reactions, transfusion-associated adverse pulmonary sequelae (including transfusion-related acute lung injury and transfusion-associated circulatory overload, expanded applications of electronic health records and issues regarding their “meaningful use” and interinstitutional “digital compatibilities”, biovigilance integration of electronic data networks within and between health care entities, and anticipated workforce contractions secondary to projected declines in the availability of qualified laboratory professionals.

    The National Blood Policy of India, 2002, advocates the disclosure of results of transfusion transmitted infections (TTI) to blood donors. However, in the absence of well-defined notification processes, and in order to avoid serious consequences resulting from unguided disclosure, blood bank personnel discard blood that is TTI-positive. We report on a survey of 105 voluntary blood donors in Kerala. Only two out of three participants had filled the donor form in the last year. Only half were aware that the blood bank was supposed to inform them if they tested positive for TTI. Fifty-seven per cent of donors wanted to be informed every time they donated blood, irrespective of a positive or negative result.

    Full Text Available Thalassemia intermedia (TI is a heterogeneous disease, in terms of both clinical manifestations and underlying molecular defects. Some TI patients are asymptomatic until adult life, whereas others are symptomatic from early childhood. In contrast with patients with Thalassemia major (TM, the severity of anemia is less and the patients do not require transfusions during at least the first few years of life. Many patients with TI, especially older ones, have been exposed to the multiple long-term effects of chronic anemia and tissue hypoxia and their compensatory reactions, including enhanced erythropoiesis and increased iron absorption. Bone marrow expansion and extramedullary hematopoiesis lead to bone deformities and liver and spleen enlargement. Therapeutic strategies in TI are not clear and different criteria are used to decide the initiation of transfusion and chelation therapy, modulation of fetal hemoglobin production, and hematopoietic stem cell transplantation on an individual basis. The clinical picture of well-treated TM patients with regular transfusionchelation therapy is better from TI patients who have not received adequate transfusion therapy. There is a significant role of early blood transfusion to prevent and treat complications commonly associated with TI, such as extramedullary erythropoiesis and bone deformities, autoimmune hemolytic anemia, leg ulcers, gallstones, pseudoxantoma elasticum, hyperuricosuria, gout and pulmonary hypertension, which are rarely seen in thalassemia major. Nowadays, indications of transfusion in patients with TI are chronic anemia (Hb < 7 g/dL, bone deformities, growth failure, extramedullary erythropoiesis, heart failure, pregnancy and preparation for surgical procedures. Conclusion: Adequate (regular or tailored transfusion therapy is an important treatment modality for increasing the quality of life in patients with thalassemia intermedia during childhood. 就临床表象和潜在的分子缺

This was achieved both by scientific advances and policy decisions regulating and supervising the activity, as well as by the quality system, which we recall that affects the entire organizational structure, responsibilities, procedures, processes and resources in place to achieve quality management. So, an effective quality system provides a framework within which activities are established, performed in a quality-focused way and continuously monitored to improve outcomes.

    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).

    Blood doping in sports has been a hot topic of present. Longitudinal follow up of hematological parameters in different endurance sports, during the 1990s and early 2000s, has provided considerable suspicions about extensive blood manipulation, with performance enhancing effects. Recent doping revelations in the media also prove that blood doping is not an anticipated myth but it is, in fact, real. Erythropoiesis stimulating agents and autologous blood transfusions are used in synergy with substantial effect on the maximum oxygen uptake and delivery to muscles. Whilst both methods of blood manipulation represent a potential health hazard, in the context of an elevated hematocrit, nevertheless despite a number of suspicious deaths amongst athletes, this has not yet been fully documented. A reliable test for detection of recombinant human erythropoietin was implemented in 2000, but this is probably circumvented by microdose regimens. The Athlete's Biological Passport represents the progeny of the idea of an indirect approach based on long term monitoring of hematological parameters, thus making it possible to detect autologous blood doping and erythropoietin use after the substance is excreted. Nevertheless with advances in anti-doping measures it is possible that the levels of excretion of substances used can be masked. Clearly more sensitive and specific diagnostic tools and research/development in these areas of major concern are warranted, which, combined with changes in the athlete's attitude, will help in reaching the vision of fair play.

  5. PREVENTIVE MEASURES FOR THE IMPROVEMENT OF THE SAFETY OF BLOOD TRANSFUSION AND VIRTUAL TRANSFUSION LABORATORY

    Full Text Available Background. Even though blood transfusion is a relatively safe form of therapy, because of the eventual administrative errors in the transfusion chain between the blood donor and the recipient of blood, transfusion errors still occur. Therefore, it is imperative to ensure an utmost extent of safety and reliability of all transfusion related procedures. The safety of blood transfusion can be improved by preventive actions, i.e. implementation of the total quality management concept, haemovigilance and virtual transfusion laboratory. In the resulting system, the information web, robotics, computer sciences and communication technologies ensure safe and reliable identification of the patients, blood donors, corresponding test samples and blood products. Apart form this; the modern technologies enable the automation of laboratory testing, the integrity of laboratory results and enable an optimal use of blood.Conclusions. For an improved transfusion safety in Slovenia, adoption of corresponding prevention as well as haemovigilance is necessary. Identification errors can be prevented by implementation of the wristbands systems with the code bars for the tagging of the patient and his biological samples, whereas the administrative errors in the blood bank and transfusion laboratory can be prevented by implementation of information systems and automation.We assume that the virtual transfusion laboratory will become an integral part of the new Slovenian transfusion web and will speed up, unify and simplify today’s methods of ordering and administering blood products. To the attending physician, it will enable the choice of optimal transfusion therapy schedule and at the same time, it will enable the supervision of individual orders, deviations and indications, all of which is needed in order to analyse and improve the quality and the costs of the treatment. These services represent the first obligatory step for the modernisation of the transfusion

    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.

    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.

    2007-01-01

    BACKGROUND: Blood transfusions may influence the recipients' cancer risks both through transmission of biologic agents and by modulation of the immune system. However, cancer occurrence in transfusion recipients remains poorly characterized. METHODS: We used computerized files from Scandinavian...... blood banks to identify a cohort of 888,843 cancer-free recipients transfused after 1968. The recipients were followed from first registered transfusion until the date of death, emigration, cancer diagnosis, or December 31, 2002, whichever came first. Relative risks were expressed as ratios...... of the observed to the expected numbers of cancers, that is, standardized incidence ratios (SIRs), using incidence rates for the general Danish and Swedish populations as a reference. All statistical tests were two-sided. RESULTS: During 5,652,918 person-years of follow-up, 80,990 cancers occurred...

    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.

    Red blood cell and component transfusions are a frequent and widely accepted accompaniment of surgical procedures. Although the risk of specific disease transmission via allogeneic blood transfusions (ABT) is very low, the occurrence of transfusion related immune modulation (TRIM) still remains a ubiquitous concern. Recent studies have shown that ABT are linked to increased morbidity and mortality across various specialties, with negative outcomes directly correlated to number of transfusions. Blood conservation methods are therefore necessary to reduce ABT. Acute normo-volemic hemodilution (ANH) along with pre-operative blood augmentation and intraoperative cell salvage are blood conservation techniques utilized in tertiary and even quaternary (transplantation) surgery in Jehovah's Witnesses with excellent outcomes. The many hematologic complications such as anemia, thrombocytopenia and coagulopathies that occur with liver transplantation present a significant barrier when trying to avoid ABT. Despite this, living donor liver transplantation (LDLT) has been successfully performed in a transfusion-free environment, providing valuable insight into the possibilities of limiting ABT and its associated risks in all patients.

    2009-06-01

    Conclusion: Both criteria of PRBC transfusion had similar clinical outcomes, although liberal transfusion resulted in a greater amount of blood transfused and a low reticulocyte count at 30 days of age. We suggest restrictive criteria for minimizing the overall amount of transfusion to less than 30 mL may be a better way of preventing CLD in VLBW infants.

    Full Text Available Hemolytic transfusion reactions represent one of the most common causes of transfusion-related mortality. Although many factors influence hemolytic transfusion reactions, complement activation represents one of the most common features associated with fatality. In this paper we will focus on the role of complement in initiating and regulating hemolytic transfusion reactions and will discuss potential strategies aimed at mitigating or favorably modulating complement during incompatible red blood cell transfusions.

    A microcapillary method utilizing phthalate esters or an ultracentrifuge method are both capable of separating autologous from homologous erythrocytes in polytransfused patients. The microcapillary technique which is readily adaptable to blood bank laboratories provides a previously unavailable method for defining blood group antigen typings in transfused patients. Such typings are of vital importance in the laboratory evaluation of transfused patients with multiple or weak blood group antibodies.

    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).

    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.

    2016-12-01

    The changing focus of transfusion medicine (TM) toward the hospital rather than the blood center and the involvement of TM specialists in a wide range of patient blood management and other specialist activities in the hospital, rather than just blood bank activities, means that the training of the transfusion specialists of the future should be under constant review. We provide overviews of the current training programs of the Accreditation Council for Graduate Medical Education in the United States and the Joint Royal Colleges of Physicians Training Board in the United Kingdom, along with specific descriptions of our own training programs at Stanford and Oxford. The numbers of TM fellows in training annually in the United States and of those who attempt to attain board certification have increased substantially over the last 20 years, despite the profound reduction in blood utilization since 2009. These trends reflect increasing job and career opportunities in new activities, such as patient blood management at hospital-based transfusion services. This trend has been seen to a lesser extent in the United Kingdom, although the focus of TM is similarly switching to hospital-based transfusion services. Based on current trends, transfusion medicine is a growing and robust specialty in the United States but perhaps less so in the United Kingdom, increasingly with hospital-centered job opportunities for improving blood utilization and clinical outcomes. Establishing pediatric TM training programs and improving research training are further opportunities for training TM specialists. © 2016 AABB.

  20. Blood transfusion safety: a new philosophy.

    Science.gov (United States)

    Franklin, I M

    2012-12-01

    Blood transfusion safety has had a chequered history, and there are current and future challenges. Internationally, there is no clear consensus for many aspects of the provision of safe blood, although pan-national legislation does provide a baseline framework in the European Union. Costs are rising, and new safety measures can appear expensive, especially when tested against some other medical interventions, such as cancer treatment and vaccination programmes. In this article, it is proposed that a comprehensive approach is taken to the issue of blood transfusion safety that considers all aspects of the process rather than considering only new measures. The need for an agreed level of safety for specified and unknown risks is also suggested. The importance of providing care and support for those inadvertently injured as a result of transfusion problems is also made. Given that the current blood safety decision process often uses a utilitarian principle for decision making--through the calculation of Quality Adjusted Life Years--an alternative philosophy is proposed. A social contract for blood safety, based on the principles of 'justice as fairness' developed by John Rawls, is recommended as a means of providing an agreed level of safety, containing costs and providing support for any adverse outcomes. © 2012 The Author.

    The study's objective was to assess the cost-effectiveness of preoperative transfusion compared with no preoperative transfusion in patients with sickle cell disease undergoing low- or medium-risk surgery. Seventy patients with sickle cell disease (HbSS/Sß(0) thal genotypes) undergoing elective surgery participated in a multicentre randomised trial, Transfusion Alternatives Preoperatively in Sickle Cell Disease (TAPS). Here, a cost-effectiveness analysis based on evidence from that trial is presented. A decision-analytic model is used to incorporate long-term consequences of transfusions and acute chest syndrome. Costs and health benefits, expressed as quality-adjusted life years (QALYs), are reported from the 'within-trial' analysis and for the decision-analytic model. The probability of cost-effectiveness for each form of management is calculated taking into account the small sample size and other sources of uncertainty. In the range of scenarios considered in the analysis, preoperative transfusion was more effective, with the mean improvement in QALYs ranging from 0.018 to 0.206 per patient, and also less costly in all but one scenario, with the mean cost difference ranging from -£813 to £26. All scenarios suggested preoperative transfusion had a probability of cost-effectiveness >0.79 at a cost-effectiveness threshold of £20 000 per QALY.

  4. Blood transfusion practices in cancer surgery

    Directory of Open Access Journals (Sweden)

    Juan P Cata

    2014-01-01

    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.

  5. Current trends in platelet transfusions practice: The role of ABO-RhD and human leukocyte antigen incompatibility

    Directory of Open Access Journals (Sweden)

    Serena Valsami

    2015-01-01

    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.

    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.

    Allergic transfusion reactions (ATRs) are a spectrum of hypersensitivity reactions that are the most common adverse reaction to platelets and plasma, occurring in up to 2% of transfusions. Despite the ubiquity of these reactions, little is known about their mechanism. In a small subset of severe reactions, specific antibody has been implicated as causal, although this mechanism does not explain all ATRs. Evidence suggests that donor, product, and recipient factors are involved, and it is possible that many ATRs are multifactorial. Further understanding of the mechanisms of ATRs is necessary so that rationally designed and cost-effective prevention measures can be developed.

    We examined possible associations between different red blood cell (RBC) transfusion strategies, overall quality of life (OQoL), and recovery of activities of daily living (ADL) in operated frail elderly hip fracture patients, and the possibility that OQoL was related to ADL recovery. A prospective, assessor-blinded, randomized controlled trial was carried out among 157 elderly residents (≥65 years) from nursing homes and sheltered housing facilities with Mini-Mental State Examination scores ≥5 points. Patients were assigned to either a restrictive RBC transfusion strategy [hemoglobin (Hb) < 9.7 g/dL, 6 mmol/L] or a liberal strategy (Hb < 11.3 g/dL, 7 mmol/L) during the first 30 days after surgery. An interview-based questionnaire, the depression list (DL) assessing OQoL, and the modified Barthel Index (MBI) assessing ADL performance, were conducted on day 30 and 1 year after hip fracture surgery. Sum-scores of DL, MBI, and their changes from day 30 until 1 year (expressing recovery) were compared between RBC transfusion groups. Possible associations between changes of DL and MBI sum-scores were tested for across total patient population. There was no association between OQoL and RBC transfusion strategies on day 30 or at 1 year. The DL sum-score changes were similar for both groups, (ie, 1.06 points) [95% confidence interval (CI) -0.62, 2.76)] P = .21. The MBI sum-scores increased at 1 year following the liberal transfusion strategy (ie, by 6.86 points) (95% CI 0.41, 13.3) P = .03. Recoveries of OQoL and ADL were associated: β = -0.06 (95% CI -0.11, -0.01) P = .02. According to our Hb threshold criteria, OQoL and RBC transfusion strategies for frail elderly hip fracture patients are not associated. However, for survivors with less severe dementia, ADL recovery after 1 year is greater following a liberal transfusion strategy than a restrictive strategy. OQoL progress and ADL recovery were associated. Copyright © 2015 AMDA – The

    Surgery, after hematology, is the biggest consumer of homologous platelet concentrates. Platelet transfusion is indicated to prevent or control bleeding associated with deficiencies in platelet number or function. In surgery, general patterns (in function of pre-surgery platelet count) can be adopted in most of the indications for platelets. In emergency situations, and in some particular cases (related to the patient, the type of operation, etc.), the transfusion procedure depends on the team's experience, the results of the available clinical and biological tests, and the drugs. Strict monitoring is required during the transfusion procedure. The efficacy of the transfusion must be controlled 1 h and 24 hours after the transfusion, and a number of factors must be assessed, namely the immunological impact of the transfusion (on red blood cells, leukocytes and platelets) and the occurrence of infectious diseases transmitted via transfusion. In addition, for a possible future transfusion, a strategy must be proposed.

    A retrospective review was performed of all shoulder arthroplasties with patients grouped on the basis of transfusion protocol time period. Group 1 had transfusions if postoperative hematocrit was multivariate analysis of significant bivariate factors were performed. Protocol change decreased transfusion rates from 16% (group 1, 153 arthroplasties) to 8% (group 2, 149 arthroplasties). Reverse shoulder arthroplasty (RTSA) transfusion rate decreased dramatically (from 24% to 5%). Transfusion rates after total shoulder arthroplasty (TSA) were low (4%) and after revision arthroplasty were high (21% + 27%) in both groups. Age, gender, heart disease, preoperative hematocrit, diagnosis, and estimated blood loss (EBL) were risk factors on bivariate analysis. Failed arthroplasty and fracture diagnoses carried high transfusion rates (25% + 28%). Logistic regression showed that low preoperative hematocrit, increased EBL, revision arthroplasty, and heart disease were transfusion risk factors. Protocol based on symptomatic anemia results in low transfusion rates after primary TSA and RTSA.

    In Sickle Cell Anemia (SCA) patient blood transfusions are an important part of treatment for stroke and its prevention. However, blood transfusions can also lead to complications such as Reversible Posterior Leukoencephalopathy Syndrome (RPLS). This brief report highlights two cases of SCA who developed such neurological complications after a blood transfusion. RLPS should be considered as the cause of neurologic finding in patients with SCA and hypertension following a blood transfusion.

    Full Text Available Extracorporeal membrane oxygenation (ECMO is frequently associated with bleeding and coagulopathy complications, which may lead to the need for transfusion of multiple blood products. However, blood transfusions are known to increase morbidity and mortality, as well as hospital cost, in critically ill patients. In current practice, patients on ECMO receive a transfusion, on average, of 1-5 packed red blood cells (RBCs/day, with platelet transfusion accounting for the largest portion of transfusion volume. Generally, adult patients require more transfusions than neonates or children, and patients receiving venovenous ECMO for respiratory failure tend to need smaller transfusion volumes compared to those receiving venoarterial ECMO for cardiac failure. Observation studies have reported that a higher transfusion volume was associated with increased mortality. To date, the evidence for transfusion in patients undergoing ECMO is limited; most knowledge on transfusion strategies was extrapolated from studies in critically ill patients. However, current data support a restrictive blood transfusion strategy for ECMO patients, and a low transfusion trigger seems to be safe and reasonable.

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

    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.

    HIV transmission in transfused blood is a high risk in Nigeria. Although official government policy directs that all blood be screened for HIV, and that all blood donation should be voluntary, there is no legal enforcement of quality of the blood supply, and at least 85% of blood is estimated to be sold by professional donors. About 75% of blood banks are based in hospitals, mostly in major cities and teaching centers. The rest of the blood banks are unregulated small commercial operations without quality control or standard refrigerators. In small health facilities it is usual to infuse 1 unit at a time, suggesting that indications for transfusion are not emergencies, but rather anemias that could be corrected with nutritional replacement. These blood units are usually donated on request by families, but more often by professional donors managed by agents. People have misconceptions about the hazards of donating blood, such as the fear that donation will bewitch, poison them, or turn them into criminals, or that it is immoral. Blood donors who may be HIV positive are rarely traceable for counseling, since they often change their names and addresses. The Nigerian government is now deliberating in committee about forming a National Blood Transfusion Service, though the efforts of the Nigerian Society of Haematology and Blood Transfusion.

    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).

    The problems that exist in our country in the security of the transfusion chain affect every step in the recruitment, donor selection, and aseptic collection, screening tests, production of blood components, storage, transportation and transfusion to recipient. Some of which can lead to fatal cases or moving slowly because of the fragmentation of our health system.With the principles of ethics, we must move towards a unified national blood system overcoming the conflicts of interest that affect the impact on administrative certifications; decrease the irrational use of resources, optimize costs and achieve a transfusion medicine security system and haemovigilance of the at the hospital. There has to be some regional blood banks well-coordinated in health institutions, with central management systems of quality and more specialized procedures,the latter can be achieved with more than 150 public blood banks, transforming them into positions of blood collection of voluntary donation of repetition.

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.

    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.

    Conclusions: Thalassemia is a chronic transfusion dependent disease complicated by the effects of iron overload on various organs leading to increased morbidity and mortality. The risk of transmission of TTI in thalassemia increases with time as number of transfusions increase. Use of advanced technology in blood screening, voluntary donations, donor selection, asepsis during blood transfusion should be used to curtail the transmission.

    patients who under go red blood cell transfusion are several: acute loss of blood after trauma, gastrointestinal hemorrhage, surgery amongst others. Currently, few studies are available regarding the use of blood components in patients at intensive care unit. Although blood transfusions are frequent in intensive care unit, the optimized criteria for handling are not clearly defined, with no available guidelines. OBJECTIVES: To analyze the clinical indications of the use of the red blood cell in the intensive care unit. METHODS: The clinical history of the patients admitted in the intensive care unit were analyzed, revisiting which had have red blood cell transfusion in the period between January 1st 2005 and December 31 2005. The study was accepted by the Research Ethics Committee - Comitê de Ética em Pesquisa (CEP - of the University of South of Santa Catarina (UNISUL. RESULTS: The transfusion rate was 19,33, and the majority of the patients were of the male gender. Their age prevalence was of 60 years old or older. The mortality rate among patients who under went red blood cell transfusion died was of 38,22%. The transfusions criterias were low serum hemoglobin (78% and the hemoglobin pre - transfusion was 8,11 g/dL. CONCLUSIONS: Politrauma and sepsis/sepsis chock were the pre diagnosis criteria. A low hemoglobin level is the main clinical criteria with average hemoglobin pre - transfusion was 8,11 g/dL.

In this paper, the one-year period prevalence rate (1-YPPR) of transfusion of red cells (RBC) is presented. Transfusion data, demographic data...... was 9.2/1000 citizens. Most of the transfused patients had a main diagnosis of neoplasm (22% of recipients), diseases of the circulatory system (15%), the digestive system (15%), injuries (13%) and diseases of the blood (8%). Age standardization reversed the relation between sex specific 1-YPPRs...

    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.

    Red blood cell transfusions can be life-saving for neonates with severe anemia or active hemorrhage. However, risks of transfusions exist and should always be weighed against potential benefits. At least two transfusion risks are unique to very low birth weight neonates. The first is an association between transfusions given in the first days after birth and the subsequent occurrence of a grade 3 or 4 intraventricular hemorrhage. The second is an association between "late" RBC transfusions and the subsequent occurrence of necrotizing enterocolitis. Much remains to be discovered about the pathogenesis of these two outcomes. Moreover, work is needed to clearly establish whether transfusions are causatively-associated with these outcomes or are co-variables. This review will provide basic data establishing these associations and propose mechanistic explanations.

  19. Effect of blood transfusions on canine renal allograft survival

    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.

    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.

    To assess the impact of safety measures, we compared reporting rates of transfusion-related reactions before and after the implementation of six measures in 1999, 2004, 2006, 2008 and 2009. Reporting rates of transfusion-transmitted bacterial infection (TTBI), viral infection (TTVI) and immune-mediated transfusion-related acute lung injury (TRALI) were calculated on the basis of confirmed annual reports and distributed blood components. The introduction of HCV NAT testing caused a significant reduction of HCV reporting rate from 1:0.6 to 1:83.16 million administered blood components (p blood components, p = 0.422). On the basis of haemovigilance data, a significant benefit could be demonstrated for four of six implemented safety measures.

  2. Thrombotic thrombocytopenic purpura secondary to ABO group incompatible blood transfusion in a patient after cardiac surgery

    Full Text Available The triggers of secondary thrombotic thrombopcytopenic purpura (TTP include drug toxicity, radiation and high-dose chemotherapy, angioinvasive infections, surgery and acute graft versus host disease. TTP secondary to surgery have been reported in a number of cases. Most of the cases have been occurred after open heart surgery. Extensive endothelial damage is held responsible as the initiating mechanism in postoperative TTP cases. However, there is no report of secondary TTP describing development owing to ABO incompatible blood transfusion. Here, we describe a patient who developed TTP after transfusion of ABO incompatible blood during hospitalization for bypass surgery. We also propose a hypothesis which may account for the possible underlying mechanism.

    There are no clear criteria for administration of blood to premature infants. In the past, indications for transfusion have included tachypnea, tachycardia, poor weight gain, apnea, bradycardia, pallor, lethargy, decreased activity, or poor feeding. Some have suggested that erythropoietin levels may also be useful in determining the need for transfusion. Data were studied from 11 premature infants with birth weights less than 1500 g collected throughout 469 hospital days. During that period the infants received a total of 37 blood transfusions. No overall relationship was found between hematocrit of 19% to 64% and heart rate, respiratory rate, or the occurrence of bradycardia; ie, these variables proved to be clinically unreliable as indicators of hematocrit. Furthermore, no predictable effect of transfusion could be identified on heart rate, respiratory rate, or on the incidence of apnea or bradycardia. It was anticipated that frequent episodes of apnea or bradycardia might increase serum erythropoietin concentration. To the contrary, more frequent bradycardia was associated with the low erythropoietin levels because those infants tended to receive transfusions for "symptomatic" anemia. The data are consistent with the concept that "anemia of prematurity" is not predictably associated with symptoms classically attributed to anemia. Possible reasons for this are that the premature infant has a different inherent response to anemia; that it is inappropriate to extrapolate symptoms of severe acute anemia to persons with mild or moderate chronic anemia; or, most likely, that other determinants of heart rate, respiratory rate, and apnea/bradycardia are of more importance than mild or moderate anemia.

    Dengue fever has emerged as a global public health problem in the recent decades. The clinical spectrum of the disease ranges from dengue fever to dengue hemorrhagic fever and dengue shock syndrome. The disease is characterized by increased capillary permeability, thrombocytopenia and coagulopathy. Thrombocytopenia with hemorrhagic manifestations warrants platelet transfusions. There is lack of evidence-based guidelines for transfusion support in patients with dengue fever. This contributes to inappropriate use of blood components and blood centers constantly face the challenge of inventory management during dengue outbreaks. The current review is aimed to highlight the role of platelets and other blood components in the management of dengue. The review was performed after searching relevant published literature in PubMed, Science Direct, Google scholar and various text books and journal articles.

  7. Blood transfusion: patient identification and empowerment.

    Science.gov (United States)

    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.

  8. Comparing the usage of autologous blood transfusion with homologous blood transfusion in spine surgery

    Full Text Available Autologous Blood Transfusion (ABT is the safest type of blood transfusion for the operator and the patient. The preoperative donation technique had already been reduced the homologous blood requirements successfully. Homologous Blood Transfusion (HBT brings more risks in complications such as transmission of diseases, anaphylactic reactions, haemolitic reactions etc. This was a parallel study, comparing one group receiving ABT and a second group receiving HBT where in both groups were performed spine surgery. The parameter used was the hemoglobin(Hb and hematocrit(Ht content preoperatively (after donation of ABT and after transfusion, total days in hospitalization after surgery. Another purpose of this study was also to achieve understandings in using ABT by considering the total patients who finally required additional HBT. There were 74 patients with diagnosis of spine fracture, tuberculous spondylitis, scoliosis, spinal stenosis and spondylolisthesis. In the ABT group the average age was 33,9 ± 14 years old and the HBT group was 29,1 ± 11,5 years old. Both groups consisted of 21 males and 16 females. Body weight of the ABT group was 55,3 ± 11,1 kg and the HBT group 52,8 ± 9,7 kg. Amount of donations preoperatively in ABT was 798,6 ± 170 cc. There were 12 patients (32,4% where the donated blood amount preoperatively did not match up the requests. There were eight patients (21,6% in the ABT group that required additional HBT of about 550 cc. Three patients (8,1% of the ABT group received transfusion that did not match the indications (blood loss < 15% of the total blood volume. The Hb and Ht content preoperatively (after donation of the ABT group significantly was less than the HBT group (p= 0,001. Hb content after transfusion in the ABT group was not significantly less than the HBT group (p = 0,30. Hospitalization days after surgery were significantly higher in the HBT group (p = 0,000. In conclusions : there was 21,6% of the ABT group

    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.

  10. [The precaution principle and blood transfusion].

    2000-06-01

    Because of the HIV and HCV virus transmission by transfusion during the eighties, there has been a retrospective reflection about the non-application of the precautionary principle, which has appeared only recently in the medical world. Since it was difficult to identify the real cause of the above-cited transmission in France, mainly because of the bad selection of blood donors, we feel we are justified in applying this precautionary principle more and more, in a monopolistic way, for biological security reasons. As a result, the biological research is not limited to looking for a 'degree zero' risk. Whether it concerns the 'PCR', the research of a new potential virus, the excessive fear regarding the transfusion of the new ESB agent, the worry caused by the blood donors who lived in the British Isles, the need for security based upon the precautionary principle is increasing endlessly. It is, however, more reasonable to consider that the precautionary principle should be essence incite a multi-disciplinary reflection involving biological sciences as well as social sciences. The precautionary principle would not make sense if it were not questioned for bad estimations, its harmful influences or its opportunistic use. Transfusion security, which is so important as a goal and as a principle, cannot appeal to the precautionary principle all the time, since the excessive use of this principle would lead to the paradox of not being able to identify the issues anymore.

    2016-03-01

    Patients with non-transfusion-dependent thalassemia (NTDT) experience a wide array of clinical complications despite their independence from frequent, regular red blood cell (RBC) transfusions. According to the current understanding of NTDT, these clinical complications stem from the interaction of multiple pathophysiological factors: ineffective erythropoiesis, iron overload, and hypercoagulability. The state of chronic anemia and hypoxia-resulting from ineffective erythropoiesis and hemolysis-leads to the expansion of the erythroid marrow and extramedullary hematopoiesis. The chronic ineffective erythropoiesis also triggers increased intestinal iron absorption and deposition in the liver and endocrine glands despite the lack of transfusional iron load. Patients with NTDT also have a higher incidence of thromboembolic disease, pulmonary hypertension, and silent cerebral ischemia. The treatment of NTDT relies on occasional or more frequent blood transfusions for certain indications (severe infection, pregnancy, and surgery), iron chelation therapy, splenectomy, and hydroxyurea. Splenectomy is no longer routinely performed in all patients with NTDT in light of its association with increased risk of NTDT-related complications. This review focuses on the clinical morbidities associated with NTDT, summarizes the mainstays of treatment, and sheds light on future therapeutic directions in the field. © 2016 New York Academy of Sciences.

  14. Effect of blood transfusions on canine renal allograft survival

    1982-04-01

    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. Futhermore, no improvement in graft survival has been found after a peroperative transfuson 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 of 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.

    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.

    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.

    Neurosurgical procedures can be complicated by significant blood losses that have the potential to decrease tissue perfusion to critical brain tissue. Red blood cell transfusion is used in a variety of capacities both inside, and outside, of the operating room to prevent untoward neurologic damage. However, evidence-based guidelines concerning thresholds and indications for transfusion in neurosurgery remain limited. Consequently, transfusion practices in neurosurgical patients are highly variable and based on institutional experiences. Recently, a paradigm shift has occurred in neurocritical intensive care units, whereby restrictive transfusion is increasingly favored over liberal transfusion but the ideal strategy remains in clinical equipoise. The authors of this study perform a systematic review of the literature with the objective of capturing the changing landscape of blood transfusion indications in neurosurgical patients.

    The influence of perioperative blood transfusion on postoperative depression of cell-mediated immunity (CMI) and the effect of ranitidine on transfusion-induced changes in postoperative CMI were investigated. CMI was assessed preoperatively and postoperatively by skin testing with seven common...... ranitidine, 50 mg intravenously every 6 hours for 72 hours, received perioperative blood transfusion. Eleven of these patients could be matched to 11 transfused patients not receiving perioperative ranitidine. Ranitidine prevented postoperative reduction in skin test response (+6% vs -55%, p less than 0.......0001). It is concluded that perioperative transfusion with whole blood amplifies the postoperative impairment in delayed hypersensitivity and that transfusion-induced postoperative impairment in delayed hypersensitivity may be prevented by perioperative ranitidine treatment....

  20. Thrombocytopenia, bleeding, and use of platelet transfusions in sick neonates.

    Science.gov (United States)

    Stanworth, Simon J

    2012-01-01

    Survival rates for infants born prematurely have improved significantly, in part due to better supportive care such as RBC transfusion. The role of platelet transfusions in neonates is more controversial. Neonatal thrombocytopenia is common in premature infants. The primary causal factors are intrauterine growth restriction/maternal hypertension, in which the infant presents with thrombocytopenia soon after birth, and sepsis/necrotizing enterocolitis, which are the common morbidities associated with thrombocytopenia in neonates > 72 hours of age. There is no evidence of a relationship between platelet count and occurrence of major hemorrhage, and cardiorespiratory problems are considered the main etiological factors in the development of intraventricular and periventricular hemorrhage in the neonatal period. Platelet transfusions are used commonly as prophylaxis in premature neonates with thrombocytopenia. However, there is widespread variation in the pretransfusion thresholds for platelet count and evidence of marked disparities in platelet transfusion practice between hospitals and countries. Platelet transfusions are biological agents and as such are associated with risks. Unlike other patient groups, specifically patients with hematological malignancies, there have been no recent clinical trials undertaken comparing different thresholds for platelet transfusion in premature neonates. Therefore, there is no evidence base with which to inform safe and effective practice for prophylactic platelet transfusions. There is a need for randomized controlled trials to define the optimal use of platelet transfusions in premature neonates, who at present are transfused heavily with platelets.

    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.

    Among the immediate transfusion reactions caused by the utilization of blood products, those suggesting immuno-allergic mechanisms posed problems for frequency, gravity, laboratory diagnosis and safety. We report here the Lille Hospital's experience over a four-year period concerning these manifestations after platelet concentrate transfusion. Eight hundred and fifty-two immediate transfusion reactions have been declared, of which 230 were allergic, which appeared in 181 patients (27%). Among the most frequent clinical signs, rash was often described (158 cases: 68.7%); less frequent were respiratory problems such as dyspnea (34 cases: 14.8%) and hypotensive reactions (18 cases: 7.8%). Seven patients presented severe reactions (3%). Twenty percent of them presented multiple allergic reactions and in 43.2%, the recurrence was more serious than the initial problem in spite of preventive medication; the use of washed blood components was necessary. The age of platelet concentrates does not appear to play a part in provoking these events (67% of platelet concentrates had been collected within four days). These allergic transfusion reactions posed problems for those who prescribe medication, because they are frequent, sometimes serious, can recur and at present, the proposed medication prevention is not always efficient.

The quality of the evidence was very low to moderate across different outcomes according to GRADE methodology. This was due to the trials being at a high risk of bias due to lack of blinding, indirectness and imprecise outcome estimates. Red cell transfusions versus standard care Children with no previous long-term transfusions Long-term transfusions probably reduce the incidence of clinical stroke in children with a higher risk of stroke (abnormal transcranial doppler velocities or previous history of silent cerebral infarct), risk ratio 0.12 (95% confidence interval 0.03 to 0.49) (two trials, 326 participants), moderate quality evidence. Long-term transfusions may: reduce the incidence of other sickle cell disease-related complications (acute chest syndrome, risk ratio 0.24 (95% confidence interval 0.12 to 0.48)) (two trials, 326 participants); increase quality of life (difference estimate -0.54, 95% confidence interval -0.92 to -0.17) (one trial, 166 participants); but make little or no difference to IQ scores (least square mean: 1.7, standard error 95% confidence interval -1.1 to 4.4) (one trial, 166 participants), low quality evidence.

    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.

    The hemoglobin threshold at which postoperative red-cell transfusion is warranted is controversial. We conducted a randomized trial to determine whether a higher threshold for blood transfusion would improve recovery in patients who had undergone surgery for hip fracture. We enrolled 2016 patients who were 50 years of age or older, who had either a history of or risk factors for cardiovascular disease, and whose hemoglobin level was below 10 g per deciliter after hip-fracture surgery. We randomly assigned patients to a liberal transfusion strategy (a hemoglobin threshold of 10 g per deciliter) or a restrictive transfusion strategy (symptoms of anemia or at physician discretion for a hemoglobin level of <8 g per deciliter). The primary outcome was death or an inability to walk across a room without human assistance on 60-day follow-up. A median of 2 units of red cells were transfused in the liberal-strategy group and none in the restrictive-strategy group. The rates of the primary outcome were 35.2% in the liberal-strategy group and 34.7% in the restrictive-strategy group (odds ratio in the liberal-strategy group, 1.01; 95% confidence interval [CI], 0.84 to 1.22), for an absolute risk difference of 0.5 percentage points (95% CI, -3.7 to 4.7). The rates of in-hospital acute coronary syndrome or death were 4.3% and 5.2%, respectively (absolute risk difference, -0.9%; 99% CI, -3.3 to 1.6), and rates of death on 60-day follow-up were 7.6% and 6.6%, respectively (absolute risk difference, 1.0%; 99% CI, -1.9 to 4.0). The rates of other complications were similar in the two groups. A liberal transfusion strategy, as compared with a restrictive strategy, did not reduce rates of death or inability to walk independently on 60-day follow-up or reduce in-hospital morbidity in elderly patients at high cardiovascular risk.

    Severe anemia, defined as a hemoglobin level of less than 5.0 g/dL, affects millions of children worldwide. The brain has a high basal demand for oxygen and is especially vulnerable to hypoxemia. Previous studies have documented neurocognitive impairment in children with severe anemia. Data on cerebral tissue oxygenation in children with severe anemia and their response to blood transfusion are limited. To measure hemoglobin saturation in cerebral tissue (cerebral tissue oxygen saturation [tSo2]) before, during, and after blood transfusion in a cohort of children presenting to hospital with severe anemia. This was a prospective, observational cohort study conducted from February 2013 through May 2015 and analyzed in July 2015 at a university hospital pediatric acute care facility in Kampala, Uganda, of 128 children, ages 6 to 60 months who were enrolled in a larger clinical trial, with a presenting hemoglobin level of less than 5.0 g/dL and a blood lactate level greater than 5mM. Most children had either malaria or sickle cell disease. Red blood cell (RBC) transfusion given as 10 mL/kg over 120 minutes. Clinical and laboratory characteristics of children with pretransfusion cerebral tSo2 levels less than 65%, 65% to 75%, and greater than 75%. Change in cerebral tSo2 as a result of transfusion. Of 128 children included in the study, oximetry results in 8 cases were excluded owing to motion artifacts; thus, 120 were included in this analysis. Cerebral tSo2 values prior to transfusion ranged from 34% to 87% (median, 72%; interquartile range [IQR], 65%-76%). Eighty-one children (67%) demonstrated an initial cerebral tSo2 level (≤75%) corresponding to an oxygen extraction ratio greater than 0.36. Patients with sickle cell disease (n = 17) and malaria (n = 15) contributed in nearly equal numbers to the subgroup with an initial cerebral tSo2 (children failed to achieve a tSo2 level greater than 75%.

    @@ One of the most vexing problems in AIHA is handling the acute situation where all blood is incompatible and the patient has severe,worsening anemia.Since the panagglutinin in the patient's serum typically reacts with all donor red cells,crossmatching donor blood is a difficult and time consuming process and probably of little benefit.The most pressing problem in a patient with previous pregnancies or transfusions is detecting alloantibody which may be hidden by the autoantibody.Sophisticated immunohematology laboratories can use a combination of procedures including differential adsorption and warm autoadsorption to identify underlying alloantibodies.

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

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

    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. Copyright © 2015 Elsevier Inc. All rights reserved.

    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.

DESIGN: Prospective study. SETTING: Heart Institute (Instituto do Coração, Hospital das Clínicas, Faculdade de Medicina, Universidade de São Paulo, Brazil. PARTICIPANTS: Twelve patients after cardiac surgery who received massive transfusion replacement; six of them evolved to a fatal outcome within the three-day postoperative follow-up. MEASUREMENTS AND MAIN RESULTS: The non-survivors group (n=6 presented high lactate levels and low P50 levels, when compared to the survivors group (p<0.05. Both groups presented an increase in oxygen consumption and O2 extraction, and there were no significant differences between them regarding these parameters. The 2,3 DPG levels were slightly reduced in both groups. CONCLUSIONS: This study shows that patients who are massively transfused following cardiovascular surgery present cell oxygenation disturbances probably as a result of O2 transport inadequacy.

    Over the past decade, there have been several studies and reviews on the importance of providing a placental transfusion to the newborn. Allowing a placental transfusion to occur by delaying the clamping of the umbilical cord is an extremely effective method of enhancing arterial oxygen content, increasing cardiac output, and improving oxygen delivery. However, premature and term newborns who require resuscitation have impaired transitional hemodynamics and may warrant different methods to actively provide a placental transfusion while still allowing for resuscitation. In this review, we will provide evidence for providing a placental transfusion in these circumstances and methods for implementation. Several factors including cord clamping time, uterine contractions, umbilical blood flow, respirations, and gravity play an important role in determining placental transfusion volumes. Finally, while many practitioners agree that a placental transfusion is beneficial, it is not always straightforward to implement and can be performed using different methods, making this basic procedure important to discuss. We will review three placental transfusion techniques: delayed cord clamping, intact umbilical cord milking, and cut-umbilical cord milking. We will also review resuscitation with an intact cord and the evidence in term and preterm newborns supporting this practice. We will discuss perceived risks versus benefits of these procedures. Finally, we will provide key straightforward concepts and implementation strategies to ensure that placental-to-newborn transfusion can become routine practice at any institution. PMID:28180126

    The Scottish National Blood Transfusion Service (SNBTS) originated in Edinburgh in the 1920's by dentist Jack Copland. Since that time the scope of Transfusion Medicine has broadened significantly to accommodate advances in technologies such as cell isolation, culture and manipulation. Many transfusion services, including SNBTS, now provide expertise both in the traditional field of blood transfusion and the newer, wider field of human cell (including 'adult' and embryonic stem cells) and tissue procurement and culture - in all the new science of "regenerative medicine". This paper describes the importance of Intellectual Property in the provision of Transfusion Medicine today and provides guidance on the management of Intellectual Property so that advances in the field have the best chance of successful translation into clinical practice.

    The objectives of this initiative were to produce nationally tested audit tools, to influence the content of national guidelines, and to enable performance indicators to be set for the clinical transfusion process. Audit tools were developed for blood transfusion practice through a collaboration between Royal Colleges and specialist Societies with an interest in blood transfusion. National audits were carried out involving 50 hospitals in the first audit and 23 of the same hospitals in the second. Over 20% of participating hospitals did not have Hospital Transfusion Committees. Most hospitals had written policies for the taking of blood samples for grouping and compatibility testing. Formal training for the phlebotomists and nurses who took blood samples was almost universal, but only one-third gave training to doctors. The audits of transfusion practice demonstrated considerable variation in the performance of standard procedures in relation to the administration of blood, and little change in practice between the two audits. The first two objectives have been met in that audit tools were developed and published, and information from the first audits was used in the development of national guidelines for the administration of blood. A significant shortfall in the systems for monitoring and delivering transfusions is present in many hospitals. This justifies pursuing the third objective but this will require a new initiative. The type of analysis and the method used for the presentation of audit data developed in this study may be useful for setting performance indicators for the clinical transfusion process.

    Background There are limited published data on the characteristics of blood transfusion recipients in sub-Saharan Africa. This study describes the demographic characteristics of blood transfusion recipients and patterns of blood and blood component use in Zimbabwe. Materials and methods Data on the characteristics of the blood transfusion recipients (age, sex, blood group), blood components received (type, quantity), discharge diagnoses and outcomes following transfusion (discharge status, duration of stay in hospital), were retrospectively collected from four major hospitals for the period from January 1, 2012 to December 31, 2012. Diagnoses were grouped into broad categories according to the disease headings of the International Classification of Diseases (ICD-10). Surgical procedures were grouped into broad categories according to organ system using ICD-9. Results Most of the 1,793 transfusion recipients studied were female (63.2%) and in the reproductive age group, i.e. 15–49 years (65.3%). The median age of the recipients was 33 years (range, 0–93). The majority of these recipients (n=1,642; 91.6%) received a red blood cell transfusion. The majority of the patients were diagnosed with conditions related to pregnancy and childbirth (22.3%), and diseases of blood and blood-forming organs (17.7%). The median time spent in hospital was 8 days (range, 0–214) and in-hospital mortality was 15.4%. Discussion Our sample of blood transfusion recipients were fairly young and most of them received red blood cell transfusions. The majority of patients in the reproductive age group received blood transfusions for pregnancy and childbirth-related diagnoses. PMID:26192782

    2011-01-01

    The phrase "patient safety" represents freedom from accidental or preventable harm due to events occurring in the healthcare setting. Practitioners aim to reduce, if not prevent, medical errors and adverse outcomes. Yet studies performed from many perspectives show that medical error constitutes a serious worldwide problem. Transfusion medicine, with its interdisciplinary intricacies and the danger of fatal outcomes, serves as an exemplar of lessons learned. Opportunity for error in complex systems is vast, and although errors are traditionally blamed on humans, they are often set up by preexisting factors. Transfusion has inherent hazards such as clinical vulnerabilities (eg, contracting an infectious agent or experiencing a transfusion reaction), but there also exists the possibility of hazards associated with process errors. Sample collection errors, or preanalytic errors, may occur when samples are drawn from donors during blood donation, as well as when drawn from patients prior to transfusion-related testing, and account for approximately one-third of events in transfusion. Errors in the analytic phase of the transfusion chain, slips and errors in the laboratory, comprise close to one-third of patient safety-related transfusion events. As many as 40% of mistransfusions are due to errors in the postanalytic phase: often failures in the final check of the right blood and the right patient at the bedside. Bar-code labels, radiofrequency identification tags, and even palm vein-scanning technology are increasingly being utilized in patient identification. The last phase of transfusion, careful monitoring of the recipient for adverse signs or symptoms, when performed diligently can help prevent or manage a potentially fatal reaction caused by an earlier process error or an unavoidable physiologic condition. Ways in which we can and do deal with potential hazards of transfusion are discussed, including a method of hazard reduction termed inherently safer design

    Blood products are commonly transfused for patients with nonvariceal upper gastrointestinal bleeding (NVUGIB). While concerns exist about further bleeding and mortality in subsets of patients receiving red blood cell (RBC) transfusion, the impact of non-RBC blood products has not previously been systematically investigated. The aim of the study was to investigate the associations between blood products transfusion, further bleeding, and mortality after acute NVUGIB. A retrospective cohort study examined further bleeding and 30-day and 1-year mortality in adult patients who underwent gastroscopy for suspected acute NVUGIB between 2008 and 2010 in three tertiary hospitals in Western Australia. Survival analysis was performed. A total of 2228 adults (63% male) with 2360 hospital admissions for NVUGIB met the inclusion criteria. Median age at presentation was 70 years (range, 19-99 years). Thirty-day mortality was 4.9% and 1-year mortality was 13.9%. Transfusion of 4 or more units of RBCs was associated with greater than 10 times the odds of further bleeding in patients with a hemoglobin level of more than 90 g/L (odds ratio, 11.9; 95% confidence interval [CI], 3.1-45.7; p ≤ 0.001), but was not associated with mortality. Administration of 5 or more units of fresh-frozen plasma (FFP) was associated with increased 30-day (hazard ratio, 2.8; 95% CI, 1.3-5.9; p = 0.008) and 1-year (hazard ratio, 2.6; 95% CI, 1.3-5.0; p = 0.005) mortality after adjusting for coagulopathy, comorbidity, Rockall score, and other covariates. In this large, multicenter study of NVUGIB, RBC transfusion was associated with further bleeding but not mortality, while FFP transfusion was associated with increased mortality in a subset of patients. © 2015 AABB.

    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

    Sepsis is one of the major causes of death worldwide, and is the host response to infection which renders our organs malfunctioning. Insufficient tissue perfusion and oxygen delivery have been implicated in the pathogenesis of sepsis-related organ dysfunction, making transfusion of packed red blood cells (pRBCs) a reasonable treatment modality. However, clinical trials have generated controversial results. Even the notion that transfused pRBCs increase the oxygen-carrying capacity of blood has been challenged. Meanwhile, during sepsis, the ability of our tissues to utilize oxygen may also be reduced, and the increased blood concentrations of lactate may be the results of strong inflammation and excessive catecholamine release, rather than impaired cell respiration. Leukodepleted pRBCs more consistently demonstrated improvement in microcirculation, and the increase in blood viscosity brought about by pRBC transfusion helps maintain functional capillary density. A restrictive strategy of pRBC transfusion is recommended in treating septic patients.

    Endoscopic laser ablation of placental vessels is now the preferred treatment for severe feto-fetal transfusion syndrome in twin gestations, and has been well-documented in triplet gestations as well. Stage IV feto-fetal transfusion syndrome was diagnosed at 20.3 weeks of gestation between two of a set of monochorionic, tetramniotic quadruplets. Endoscopic laser ablation occurred at 20.4 weeks. Feto-fetal transfusion recurred at 22 weeks between the initial donor and the two previously unaffected fetuses. Delivery occurred at 24.9 weeks. The donor and one of the corecipients died shortly after birth. The sole survivor was doing well. Treatment of feto-fetal transfusion syndrome in higher-order gestations is challenging because of the increased pregnancy risks, the difficult angioarchitecture and the risk of recurrence.

    The field of transfusion medicine is on the threshold of a paradigm shift, as the technology for genotyping of red blood cell antigens, including US FDA-approved arrays, is now moving into standard practice. Access to cost-efficient, high-resolution genotyping has the potential to increase the quality of care by decreasing the risk for alloimmunization and incompatible transfusions in individuals on long-term blood transfusion protocols, including patient groups with hemoglobinopathies and other chronic diseases. Current and future applications of molecular methods in transfusion medicine and blood banking are discussed, with emphasis on indications for genotyping in various clinical scenarios. Furthermore, limitations of the current gold standard methodology and serology, as well as of contemporary molecular methodology, are examined.

    Abstract Based on the mechanism of pathophysiology, thalassemia major or transfusion-dependent thalassemia patients may have an increased risk of developing organic erectile dysfunction resulting from hypogonadism. However, there have been few studies investigating the association between erectile dysfunction and transfusion-naive thalassemia populations. We constructed a population-based cohort study to elucidate the association between transfusion-naive thalassemia populations and organic erectile dysfunction This nationwide population-based cohort study involved analyzing data from 1998 to 2010 obtained from the Taiwanese National Health Insurance Research Database, with a follow-up period extending to the end of 2011. We identified men with transfusion-naive thalassemia and selected a comparison cohort that was frequency-matched with these according to age, and year of diagnosis thalassemia at a ratio of 1 thalassemia man to 4 control men. We analyzed the risks for transfusion-naive thalassemia men and organic erectile dysfunction by using Cox proportional hazards regression models. In this study, 588 transfusion-naive thalassemia men and 2337 controls were included. Total 12 patients were identified within the thalassaemia group and 10 within the control group. The overall risks for developing organic erectile dysfunction were 4.56-fold in patients with transfusion-naive thalassemia men compared with the comparison cohort after we adjusted for age and comorbidities. Our long-term cohort study results showed that in transfusion-naive thalassemia men, there was a higher risk for the development of organic erectile dysfunction, particularly in those patients with comorbidities.

    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.

    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

    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

    The aim of this study was to develop two novel risk prediction scores for transfusion and bleeding that would be used to inform treatment decisions, quality assurance, and clinical trial design in cardiac surgery. Clinical data prospectively collected from 26 UK cardiac surgical centres and a single European centre were used to develop two risk prediction models: one for any red blood cell (RBC) transfusion, and the other for large volume blood transfusion (≥4 RBC units; LVBT), an index of severe blood loss. 'Complete case' data were available for 24 749 patients. Multiple imputation was used for missing covariate data (typically data set containing 39 970 patients. Risk models were developed in the complete case data set, with internal validation using leave-one-centre-out cross-validation. The final selected models were fitted to the imputed data set. Final risk scores were then compared with the performance of three existing scores: the Transfusion Risk and Clinical Knowledge score (TRACK), the Transfusion Risk Understanding Scoring Tool (TRUST), and the Papworth Bleeding Risk Score (BRiSc). The area under the receiver operating characteristic curve (AUC) was 0.77 (95% confidence interval 0.77-0.77) for the any RBC transfusion score and AUC 0.80 (0.79-0.80) for the LVBT score in the imputed data set. The LVBT model also showed excellent discrimination (Hosmer-Lemeshow P=0.32). In the imputed data set, the AUCs for the TRACK and TRUST scores for any RBC transfusion were 0.71 and 0.71, respectively, and for LVBT the AUC for the BRiSc score was 0.69. Two new risk scores for any RBC transfusion or LVBT among cardiac surgery patients have excellent discrimination, and could inform clinical decision making. © The Author 2015.

    Chronic graft versus host disease (GVHD) is a less frequently seen disease that occurs post solid organ or bone marrow transplantation. Chronic GVHD occurring post blood transfusion is an even more uncommon disease. It can present either as a lichenoid disease or as a sclerodermatous disease involving multiple systems. In this article, we report a case of chronic graft versus host reaction occurring in skin secondary to blood 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.

    The act to transfuse is a prescription following basic rules similar to drug prescriptions. If harm happens, potentially linked with this prescription, the harm's responsibility is borne by the physician, the paramedics, the care organization but by the supplier laboratory too. The setting of good practice rules consistent with science data at the time when the act is performed, the respect of the patient's rights and the quality of supplied products will be assessed during the expertise. Under restorative responsibility, it is necessary to previously establish a direct and certain causation between the litigious act and the harm to enforce the vicarious liability. Nowadays, legal precedents grant a larger protection to more and more numerous victims, enhancing the field of the fault with the appeal to assumption of fault. At the same time, the lawmaker himself promulgated objective conditions of compensation for many categories of victims of medical risk from which transfused people are part. The law of March the 4th of 2002 went one step closer devoting a new foundation of compensation: national solidarity.

  9. Platelet transfusion in chemotherapy patients: comparison of the effect of intravenous infusion pumps versus gravity transfusion.

    Platelet concentrates are given to patients suffering with severe thrombocytopenia usually by a gravity transfusion procedure. Increasing patient numbers that are in need of this treatment increase the pressure on hospital staff and space. In order to combat time issues, the use of medical devices such as intravenous infusion pumps are thought to be beneficial for time and simultaneously for safety in transfusion practices. By using infusion pumps, platelet concentrates can be transfused in less time and provide accurate volume measurements. Manufacturers of infusion pumps claim that these devices are safe to be used for blood products including platelet concentrates. However, published studies were performed on older models and newer devices are on the market now. The purpose of this study is to evaluate infusion pumps, which are claimed to be suitable for blood products and to investigate the impact the pumps had on platelets. Furthermore, the study revealed if the intravenous infusion pumps are safe to be used for platelet transfusion as claimed by manufacturers. A simulated transfusion was performed using the Carefusion Alaris GP Plus volumetric pump and Fresenius Kabi Volumat Agilia infusion pump. Samples were taken from expired platelet concentrates before and after passage through the pump. All samples were investigated for full blood count that included platelet count, mean platelet volume (MPV), platelet distribution width (PDW) and a plateletcrit (PCT). The samples were then centrifuged to achieve platelet-poor plasma and then tested for lactate dehydrogenase (LDH). A power calculation performed on the statistical power analysis program G*power indicated a requirement of 82 samples for a power of 80%. Statistical analysis was performed with the IBM SPSS statistic software. A paired sample t-test was used to calculate mean, standard deviation and P values for the infusion pumps used. The Wilcoxon Signed Rank Test was used to evaluate results that had a non

    In-utero transfusion is now well under control and improves the survival of foetuses monitored for fetal anemia with a survival rate of more than 80 %. The aim was to evaluate short-term neonatal outcome after fetal severe anemia managed by intrauterine transfusions. We did a retrospective study of all neonates born after management of severe fetal anemia (n = 93) between January 1999 and January 2013 in our regional center. The two main causes of anemia were maternal red blood cell alloimmunization (N = 81, 87 %) and Parvovirus B19 infection (N = 10, 10.8 %). In the alloimmunization group, phototherapy was implemented in 85.2 % of cases with a maximum level of bilirubin of 114.4 ± 60.7 (mg/dl). Transfusion and exchange transfusion were, respectively, required in 51.9 % and in 34.6 % of cases. One neonate presented a convulsive episode, and we observed three neonatal deaths. In the parvovirus group, none of the child had anemia at birth and no management was necessary. Contemporary management of Rhesus disease is associated with encouraging neonatal outcomes. In case of Parvovirus infection, no specific management is necessary at. But, in all cases of fetal anemia, children should be followed up with particular attention to neurologic development. • In-utero transfusion is now well under control and improves the survival of fetuses monitored for fetal anemia. • Limited studies are available on the effect of IUT on postnatal outcome in infants with a history of fetal anemia. What is New: • Contemporary management of severe Rhesus disease is associated with encouraging neonatal outcomes. • The majority of infants can be managed with phototherapy and a limited number of top-up transfusions and exchange transfusions. In case of Parvovirus infection, the short-term neonatal outcome is excellent.

    Over the past few decades, transfusion medicine and haemotherapy have evolved into complex medical disciplines comprising a broad field of subspecialties such as immunohaematology, blood component production, haemapheresis and haemostaseology. Transfusion medicine is thus an important qualification at the interfaces of analytical laboratory medicine, pharmaceutical production and clinical disciplines such as internal medicine, anaesthesiology or surgery. Physicians specialising in transfusion medicine are valuable and competent partners for these related disciplines when it comes to safe, effective and tailored haemotherapy. Why has transfusion medicine become so complex? On the one hand, one can discern problems such as infectious diseases like the HIV disaster in the past century, resulting in guidelines, directives and laws such as the transfusion law in Germany. Thereby, we now enjoy the highest level of blood product safety ever regarding viral transmission thanks to the broad implementation of PCR testing. On the other hand, there are numerous positive reasons for the increasing complexity of transfusion medicine: Modern medical therapies like stem cell transplantation, cellular therapy, transplantation of solid organs, regenerative medicine and surgery cannot exist without a safe supply of blood products and high quality standard as well as special blood products and laboratory services provided by blood banks and transfusion medicine specialists. Good laboratory practice (GLP), good manufacturing practice (GMP), quality management systems and quality control on the pharmaceutical manufacturer's level are only few examples of the standards in today's blood banking. European directives in the field of blood products, stem cell preparations and tissue have led to higher uniform quality standards for biological preparations in a unified Europe, which is the desired outcome, but which also increases the complexity of this field. In contrast, directives 93/16/EEC

    While engaged in the repair of a zinc furnace, 4 workers were accidentally exposed to arsenious hydride (AsH3) fumes. Acute intravascular haemolysis developed within a few hours. On admission, the patients immediately underwent exsanguino-transfusion; 8.2 to 10.2 l of blood were exchanged through a continuous perfusion pump at the rate of 1 l/hour. Two patients resumed diuresis during transfusion, but the other two required repeated haemodialysis. Between the 10th and 30th days, while renal function was gradually returning to normal, mildly megaloblastic anaemia developed. This was followed during the 3rd month by clinical and electric signs of polyneuritis of the lower and upper limbs, which subsequently regressed. Regular measurements of arsenic levels in the blood and urine were performed between and during exsanguino-transfusion and haemodialysis.

    Full Text Available Background: Blood transfusion as a part health services should be provided under appropriate indications and in a safe manner. In Indonesia, blood collection is run by the Blood Transfusion Unit of Indonesian Red Cross, where the blood is screened, processed into blood components, and finally distributed to hospitals. The purpose of this study was to describe the profile of blood transfusion requests from hospitals that do not have blood bank facility to the Bandung Blood Transfusion Unit, Indonesian Red Cross. Methods: A descriptive study was carried out using secondary data from Bandung Blood Transfusion Unit Indonesian Red Cross (UTD PMI Bandung. All blood request forms from hospitals during 2011 were collected and analyzed. Variables in this study were the amount of blood units, blood components, blood type, and indications of blood transfusion. Results: The number of blood units requested by hospitals were 35,841 units. The most blood units requested was in August 2011. The blood component requested was the packed red cell (61.1%, whole blood (17.4%, thrombocyte concentrate (10.6%, and fresh frozen plasma (7%. The total percentage of O, A, B and AB blood types were 36.1%, 28.6%, 27.5%, and 7.9% respectively. The most frequent indication for transfusion was anemia (61.7%, followed by surgery and other causes of bleeding. Conclusions: The total blood units requested by hospitals vary each month. The most blood component requested is Packed Red Cell and the type of blood is O blood type. The most frequent indication is anemia.

    In a patient with sickle cell disease receiving chronic transfusion, exacerbation of anemia with reticulocytopenia must prompt consideration of a delayed hemolytic transfusion reaction with hyperhemolysis, as further transfusion may worsen this condition; definitive diagnosis is sometimes difficult. Anemia evolving during parvovirus B19-induced erythroid hypoplasia (transient aplastic crisis) should be attenuated in chronic transfusion patients due to superior survival of transfused over endogenous red blood cells. A 16-year-old with sickle cell disease receiving chronic transfusion of modified intensity (goal to maintain hemoglobin Sanemia with reticulocytopenia was later shown to have had transient aplastic crisis.

    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 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.

    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.

    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.

  19. The use of big data in transfusion medicine.

    2015-06-01

    '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. © 2015 British Blood Transfusion Society.

  20. Anti-Kpa-induced severe delayed hemolytic transfusion reaction.

    Koshy, R; Patel, B; Harrison, J S

    2009-01-01

    Kpa is a low-frequency antigen occurring in less than 2 percent of the Caucasian population. Mild to moderate delayed hemolytic transfusion reactions (DHTR) and hemolytic disease of the fetus and newborn attributable to anti-Kpa have been reported. Severe overt DHTR has not been reported with anti-Kpa. A case of a severe DHTR attributed to anti-Kpa after multiple RBC transfusions is being reported. A 52-year-old Caucasian woman received multiple units of RBCs for a lower gastrointestinal bleed. She was referred to our institution for hepatic and renal failure, which was supported by laboratory findings of peak LDH, bilirubin, BUN, and creatinine elevations. Hemoglobin had dropped on Day 10 after transfusion. The DAT and antibody screen (ABS) were negative. Initial workup and subsequent ABS were negative. Anti-Kpa was identified when an additional RBC panel was tested. One of the RBC units transfused was incompatible by antihuman globulin (AHG) crossmatch with the patient's plasma and typed positive for Kpa. DHTR was confirmed after extensive workup. The patient responded to supportive therapy and experienced an uneventful recovery. DHTR may not be considered when DAT and ABS are negative. However, correlation of recent transfusion with signs and symptoms should alert the clinician to entertain and investigate a DHTR that should include the AHG crossmatch of all implicated RBC units. The severity of the reaction also raises concerns as to when and what antigen specificity should be considered for inclusion in the antibody screening cells.

    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.

    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.

    - Plasma transfusion guidelines support patient care and safety, management of product wastage, and compliance; yet, there is little information across multiple institutions about use of and adherence to plasma transfusion guidelines. - To survey multiple institutions regarding their plasma transfusion guidelines and compliance, plasma wastage rates, and incidence of transfusion reactions associated with plasma transfusion. - The College of American Pathologists Q-Probes model was used to collect data from 89 participating institutions. Each site was asked to provide data relevant to its most recent 40 adult patient plasma transfusion episodes, and complete a questionnaire regarding plasma transfusion guidelines, utilization and wastage of plasma, and transfusion reactions related to plasma transfusion. - The participating institutions reported a total of 3383 evaluable plasma transfusion episodes with transfusion of 9060 units of plasma. Compliance with institution-specific guidelines was seen in 3018 events (89%). Pretransfusion and posttransfusion coagulation testing was done in 3281 (97%) and 3043 (90%) of these episodes, respectively. Inappropriate criteria were noted for more than 100 transfusion episodes. Thirty-two plasma transfusion episodes (1%) were associated with a transfusion reaction. Serious and fatal reactions were reported. Median plasma wastage rate for the year preceding the study was 4.5%. - Most participating institutions are compliant with plasma transfusion guidelines based on published references, supported by appropriate testing. With transfusions for indications that lack evidence of efficacy and incidence of transfusion reactions, there is an ongoing role for transfusion service leaders to continue to update and monitor plasma transfusion practices.

    BACKGROUND: Blood transfusion may reduce survival after curative surgery for solid tumors. This may be related to extracellular content of cancer growth factors present in transfusion components. Vascular endothelial growth factor (VEGF) is a potent stimulator of angiogenesis in solid tumors....... The potential content of VEGF in various blood components for transfusion was evaluated. STUDY DESIGN AND METHODS: Soluble VEGF (sVEGF, isotype 165) was determined by an enzyme-linked immunosorbent assay (EIA) in serum and plasma samples and in lysed cells from healthy volunteers. Subsequently, total content...... of platelet-derived soluble plasminogen activator inhibitor type 1 (sPAI-1) was determined by an EIA in the same samples. Finally, the extracellular accumulation of sVEGF was determined in nonfiltered WB and SAGM blood during storage for 35 days and in BCP pools during storage for 7 days. RESULTS...

    Compartment syndrome is a serious condition characterized by raised intracompartmental pressure, which develops following trauma. Well leg compartment syndrome (WLCS) is a term reserved for compartment syndrome in a nontraumatic setting, usually resulting from prolonged lithotomy position during surgery. In literature, 8 cases have been reported regarding well leg compartment syndrome in a supine position and bilateral symmetrical involvement was observed in only 2 cases. In WLCS etiology, lengthy surgery, lengthy hypotension, and extremity malpositioning have been held responsible but one of the factors with a role in the etiology may have been the tissue oedema and impaired microcirculation formed from the effect of vasoactive mediators expressed into the circulation associated with the massive blood transfusion. The case is presented here regarding symmetrical lower extremity compartment syndrome after surgery in which massive transfusion was made for gross haemorrhage from an abdominal injury. In conclusion, blood transfusion applied at the required time is life-saving but potential risks must always be considered.

    2014-12-01

    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.

    Plasma transfusions are given to patients with coagulopathy, either prophylactically, before an invasive procedure; or therapeutically, in the presence of active bleeding; and as an exchange fluid in therapeutic plasma exchange for disorders such as thrombotic thrombocytopenic purpura. There is consensus that many prophylactic plasma transfusions are non-efficacious, and the misdiagnosis of thrombotic thrombocytopenic purpura results in unnecessary therapeutic plasma exchange. Beginning in 2001, programs to reduce plasma transfusion in the three major teaching hospitals in Rhode Island were initiated. The programs evolved through the establishment of guidelines, education for key prescribers of plasma, screening of plasma prescriptions, and engagement of individual prescribing physicians for out-of-guidelines prescriptions with modification or cancellation. Establishment of an in-house ADAMTS13 (ADAM metallopeptidase with thrombospondin type 1, motif 13) assay in 2013 was used to prevent therapeutic plasma exchange in patients with non-thrombotic thrombocytopenic purpura microangiopathy. Transfusion service data were gathered at the hospital level regarding blood component use, hospital data for discharges, inpatient mortality, and mean case-mix index, and, at the state level, for units of plasma shipped from the community blood center to in-state hospitals. Between 2006 and 2016, a reduction in plasma use from 11,805 to 2677 units (a 77% decrease) was observed in the three hospitals and was mirrored in the state as a whole. This decline was not associated with any increase in red blood cell transfusion. Inpatient mortality either declined or was unchanged. An active program focused on education and interdiction can achieve a large decrease in plasma transfusions without evidence of patient harm. © 2017 AABB.

    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.

    Beta-thalassemia major is a chronic disorder of blood, having an extensive impact on the affected child. It involves lifelong therapeutic regime, with repeated blood transfusions. With improved life expectancy, due to improved medical management psychosocial aspects of thalassemia are gaining importance. To assess the behavioral problems in multi-transfused thalassemic children and psychosocial factors affecting them. The study was conducted in a tertiary care level hospital and research institute catering mainly to a population of low socioeconomic status. The study was a cross-sectional study involving 50 multi-transfused thalassemic children of age 5-10 years. Fifty multi-transfused thalassemic children, aged 5-10 years, not suffering from any other major medical illness, were included. Child Behavior Check List (Achenbach) (CBCL) was used to collect data from each parent regarding the child's behavior. Parental Attitude Scale (Rangaswamy 1989) was applied. Descriptive statistical analysis was used with analysis of variance (ANOVA) and Student's t test to find the significance of data. The CBCL total scores were high in 32% patients, indicating the presence of behavioral problems. Higher CBCL scores were found in children of older age group, those with poor school performance, whose mothers' education was more than eighth standard, had history of death of thalassemic relative in family, greater duration of diagnosed illness, poor pre-transfusion hemoglobin level, and who had longer periods of school absenteeism. Behavioral problems are common in multi-transfused thalassemic children. Early diagnosis and intervention of behavioral problems in these children would make them cope with thalassemia better.

    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.

    2005-01-01

    Full Text Available In Canada and other countries, many steps are taken to minimize the risk of infection through the transfusion of blood or blood products (1. However, the infection risk can never be zero because these are biological products that are taken from living donors who are never 'germ free' (2. This is in contrast to drugs that can be manufactured de novo under sterile conditions in a laboratory. The present note provides an update on transfusion infection risks in Canada. It replaces the 2004 note (3 and may be helpful to practitioners in discussions with patients and parents toward obtaining informed consent before blood or blood product administration.

    2013-01-01

    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

    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.

    An inquiry amongst blood transfusion services served to establish at 19 the number of known transfusion associated HIV infections in Switzerland. In 12 cases the transfusion of an anti-HIV positive blood unit could be proven retrospectively, while in 7 cases an HIV-infected blood donor could not be found but the association of the infection with blood transfusion is highly probable by exclusion of other risk factors. All these infections occurred before introduction of anti-HIV screening in Switzerland in November 1985. After this date no new transfusion associated HIV infections have been reported. It is estimated that there are fewer than 170 transfusion associated HIV infections in Switzerland. The probability of infection with AIDS by blood transfusion is less than 1:500,000. Blood transfusion today appears to be as safe as before the emergence of the AIDS epidemic.

    A serologic study of Chagas disease was performed in 110 patients submitted to chronic hemodialisis and blood transfusions. Immunofluorescence antibody testing (IgG and IgM) was positive in 6 out of 62 patients receiving multiple blood transfusions (9.7%), but negative in all 48 subjects without transfusions. Thus, repeated blood transfusion is a significant risk for T cruzi infection in chronic hemodialized patients.

    Life-long red blood transfusion remains the main treatment for severe thalassemia. The development of hemolytic alloantibodies and erythrocyte autoantibodies complicated transfusion therapy in thalassemia patients. The frequency causes and prevention of this phenomenon among 80 transfused thalassemia patients were evaluated in Ali Asghar Children's Hospital during 1998-2004 in a cross-sectional study. In our study the mean age at the initiation of transfusion was 1.7 years (SD = 1.94) an...

    The transfusion-related respiratory complications, transfusion-related acute lung injury (TRALI) and transfusion-associated circulatory overload (TACO), are leading causes of transfusion-related morbidity and mortality. At present, there are no effective preventive strategies with red blood cell (RBC) transfusion. Although mechanisms remain incompletely defined, soluble biological response modifiers (BRMs) within the RBC storage solution may play an important role. Point-of-care (POC) washing of allogeneic RBCs may remove these BRMs, thereby mitigating their impact on post-transfusion respiratory complications. This is a multicenter randomised clinical trial of standard allogeneic versus washed allogeneic RBC transfusion for adult patients undergoing cardiac surgery testing the hypothesis that POC RBC washing is feasible, safe, and efficacious and will reduce recipient immune and physiologic responses associated with transfusion-related respiratory complications. Relevant clinical outcomes will also be assessed. This investigation will enrol 170 patients at two hospitals in the USA. Simon's two-stage design will be used to assess the feasibility of POC RBC washing. The primary safety outcomes will be assessed using Wilcoxon Rank-Sum tests for continuous variables and Pearson chi-square test for categorical variables. Standard mixed modelling practices will be employed to test for changes in biomarkers of lung injury following transfusion. Linear regression will assess relationships between randomised group and post-transfusion physiologic measures. Safety oversight will be conducted under the direction of an independent Data and Safety Monitoring Board (DSMB). Approval of the protocol was obtained by the DSMB as well as the institutional review boards at each institution prior to enrolling the first study participant. This study aims to provide important information regarding the feasibility of POC washing of allogeneic RBCs and its potential impact on ameliorating

    Essentials Anti-activated factor X (Anti-Xa) monitoring is more precise than activated partial thromboplastin (aPTT). 20 804 hospitalized cardiovascular patients monitored with Anti-Xa or aPTT were analyzed. Adjusted transfusion rates were significantly lower for patients monitored with Anti-Xa. Adoption of Anti-Xa protocols could reduce transfusions among cardiovascular patients in the US. Background Anticoagulant activated factor X protein (Anti-Xa) has been shown to be a more precise monitoring tool than activated partial thromboplastin time (aPTT) for patients receiving unfractionated heparin (UFH) anticoagulation therapy. Objectives To compare red blood cell (RBC) transfusions between patients receiving UFH who are monitored with Anti-Xa and those monitored with aPTT. Patients/Methods A retrospective cohort study was conducted on patients diagnosed with acute coronary syndrome (ACS) (N = 14 822), diagnosed with ischemic stroke (STK) (N = 1568) or with a principal diagnosis of venous thromboembolism (VTE) (N = 4414) in the MedAssets data from January 2009 to December 2013. Anti-Xa and aPTT groups were identified from hospital billing details, with both brand and generic name as search criteria. Propensity score techniques were used to match Anti-Xa cases to aPTT controls. RBC transfusions were identified from hospital billing data. Multivariable logistic regression was used to identify significant drivers of transfusions. Results Anti-Xa patients had fewer RBC transfusions than aPTT patients in the ACS population (difference 17.5%; 95% confidence interval [CI] 16.4-18.7%), the STK population (difference 8.2%; 95% CI 4.4-11.9%), and the VTE population (difference 4.7%; 95% CI 3.3-6.1%). After controlling for patient age and gender, diagnostic risks (e.g. anemia, renal insufficiency, and trauma), and invasive procedures (e.g. cardiac catheterization, hemodialysis, and coronary artery bypass graft), Anti-Xa patients were less likely to have a transfusion while

Some workers have reported improved survival when adjunct exchange blood transfusion is included in the treatment modality while others opine against it. This review is an effort to address and critically appraise current evidence for the treatment mode for severe malaria. The literature was searched with a specified search strategy to identify reports of children who underwent exchange transfusion for severe malaria. Total 23 children who underwent exchange transfusion for severe falciparum malaria published by 9 authors were identified. Age ranged from 5 months to 16 years with a mean age of 6.4 years. The average preprocedure parasite index (PI) was 41.4% (95confidence interval [CI]; 31.2-51.4). The average blood volume exchanged was 118.6% (95% CI; 94.7-143) of the circulating blood volume.

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

    Storing packed red blood cells (pRBCs) increases the potassium concentration. This effect is characterized in citrate phosphate dextrose/citrate phosphate dextrose adenine units but not published for Adsol (AS-5) units. The change in whole-blood potassium concentration in pediatric patients during routine transfusion is also poorly characterized. In this study, pediatric patients undergoing transfusion had pre- and posttransfusion whole-blood potassium measurements. The pRBC unit transfused and the unit's segment were sampled, with potassium concentration measured. In addition, potassium concentration in AS-5 units was measured over 42 days of storage. Unit extracellular potassium increased in AS-5 units after day 7 at 0.83 mmol/L/d. The mean change in patient potassium concentration was 0.08 mmol/L (range, -0.5 to 0.5 mmol/L). No correlation with unit age or unit potassium concentration was identified with change in patient whole-blood potassium concentration. The lack of clinical effect on patient potassium does not support the use of "fresh" pRBC units with routine pediatric transfusion.

    Full Text Available The thalassemias are a group of inherited disorders of hemoglobin synthesis characterized by various degrees of defective production of the α- or β-globin chains of adult hemoglobin A. Non-transfusion- dependent thalassemia (NTDT includes a group of thalassemia patients who do not require regular RBC transfusions for survival, but may require occasional transfusions due to infection or pregnancy or may require more regular transfusions later in life due to splenomegaly or other complications. Due to the rising phenomenon of global migration, this previously well-localized entity is currently spreading more and more worldwide reaching Northern America and Northern Europe. The clinical picture of NTDT is governed by the severity of the ineffective erythropoiesis and the chronic hemolytic anemia, which, in turn, lead to iron overload, hypercoagulability, and an array of clinical complications involving almost every organ system. Patients with NTDT suffer from complications that are distinct from those encountered in patients with transfusion- dependent thalassemia (TDT in addition to the complications shared by both TDT and NTDT. As a consequence, patients with NTDT deserve a care specifically tailored to their needs. In the care of patients with NTDT, aiming at a standardized yet personalized care is not an easy task especially that NTDT patients lie on a heterogeneous spectrum with a wide variability in their clinical presentation and response to therapy. Therefore, guidelines emerge as a necessity to answer the specific needs of NTDT patients and the clinicians caring for them. In this article, we summarize the complications most commonly associated with NTDT and the recommendations of the guidelines for the management of patients with NTDT, based on the best available evidence.

    2015-09-01

    Babesiosis is a potentially life-threatening zoonotic disease that is endemic to the northeastern United States and increasing in prevalence worldwide. Transmitted by the same Ixodes tick responsible for Lyme disease, the intraerythrocytic parasite Babesia causes a wide range of clinical presentations--from asymptomatic carriage to a fulminant course with rapid deterioration. Symptoms typically present 1 to 6 weeks after inoculation, with the gradual onset of fatigue, malaise, weakness, and intermittent or sustained fever as high as 40.9°C. Severe cases are associated with parasitemia greater than 4%, alkaline phosphatase greater than 125 U/L, and white blood cell counts greater than 5×10(9)/L. Definitive diagnosis is made by microscopic examination of thin blood smears, polymerase chain reaction, and indirect immunofluorescent antibody testing. The increasing frequency of babesiosis paired with a lack of blood-donor screening assays poses a serious threat to the safety of the US blood supply. Although babesiosis is responsible for 3.6% of transfusion-related deaths, the Food and Drug Administration has yet to approve mandatory screening for the parasite in donated blood. Historically, transfusion-transmitted babesiosis has been thought to be isolated to the immunocompromised patient population. However, a recent case of transfusion-transmitted babesiosis in an immunocompetent patient following total hip arthroplasty is the first reported in the literature and may represent a growing risk to a far greater segment of the population than previously thought. This article summarizes the current state of transfusion-transmitted babesiosis and the detrimental impact of this infection on blood transfusion safety. Copyright 2015, SLACK Incorporated.

    To review the pathophysiology of anemia, as well as transfusion-related complications and indications for red blood cell (RBC) transfusion, in critically ill children. Although allogeneic blood has become increasingly safer from infectious agents, mounting evidence indicates that RBC transfusions are associated with complications and unfavorable outcomes. As a result, there has been growing interest and efforts to limit RBC transfusion, and indications are being revisited and revamped. Although a so-called restrictive RBC transfusion strategy has been shown to improve morbidity and mortality in critically ill adults, there have been relatively few studies on RBC transfusion performed in critically ill children. Published literature on transfusion medicine and outcomes of RBC transfusion. STUDY SELECTION, DATA EXTRACTION, AND SYNTHESIS: After a brief overview of physiology of oxygen transportation, anemia compensation, and current transfusion guidelines based on available literature, risks and outcomes of transfusion in general and in critically ill children are summarized in conjunction with studies investigating the safety of restrictive transfusion strategies in this patient population. The available evidence does not support the extensive use of RBC transfusions in general or critically ill patients. Transfusions are still associated with risks, and although their benefits are established in limited situations, the associated negative outcomes in many more patients must be closely addressed. Given the frequency of anemia and its proven negative outcomes, transfusion decisions in the critically ill children should be based on individual patient's characteristics rather than generalized triggers, with consideration of potential risks and benefits, and available blood conservation strategies that can reduce transfusion needs.

    Background: Blood loss and replacement is still a controversial issue in major orthopaedic surgery. Allogenic blood transfusion may cause legal problems and concerns regarding the transmission of transfusion-related diseases. Cellsaver Systems (CSS) were developed as an alternative to allogenic transfusion but CSS transfusion may cause coagulation, infection and haemodynamic instability. Aims: Our aim was to analyse the efficiency and cost analysis of a cell saver auto-transfusion system in the total knee arthroplasty procedure. Study Design: Retrospective comparative study. Methods: Those patients who were operated on by unilateral, cemented total knee arthroplasty (TKA) were retrospectively evaluated. Group 1 included 37 patients who were treated using the cell saver system, and Group 2 involved 39 patients who were treated by allogenic blood transfusion. The groups were compared in terms of preoperative haemoglobin and haematocrit levels, blood loss and transfusion amount, whether allogenic transfusion was made, degree of deformity, body mass index and cost. Results: No significant results could be obtained in the statistical comparisons made in terms of the demographic properties, deformity properties, preoperative laboratory values, transfusion amount and length of hospital stay of the groups. Average blood loss was calculated to be less in Group 1 (p<0.05) and cost was higher in Group 1 (p<0.05). Conclusion: Cell saver systems do not decrease the amount of allogenic blood transfusion and costs more. Therefore, the routine usage of the auto-transfusion systems is a controversial issue. Cell saver system usage does not affect allogenic blood transfusion incidence or allogenic blood transfusion volume. It was found that preoperative haemoglobin and body mass index rates may affect allogenic blood transfusion. Therefore, it is foreseen that auto-transfusion systems could be useful in patients with low haemoglobin level and body mass index. PMID:25207187

  17. The use of fresh whole blood transfusions by the SOF medic for hemostatic resuscitation in the austere environment.

    The leading cause of death on the battlefield is uncontrolled hemorrhage. Non-compressible (truncal) hemorrhage is the cause over two thirds of these deaths. This makes truncal hemorrhage the leading cause of potentially survivable death on the battlefield. Over one third of the casualties who arrive at the emergency department (ED) or combat surgical hospital (CSH) in need of a blood transfusion are already suffering from acute traumatic coagulopathy which is associated with an 80% mortality. Early aggressive treatment and prevention of this coagulopathy through hemostatic resuscitation has been shown to increase survival. Hemostatic resuscitation involves the very early use of blood and blood products as primary resuscitation fluids to both treat intrinsic acute traumatic coagulopathy and prevent the development of dilutional coagulopathy. Few, if any, of the products used in hemostatic resuscitation are currently available to the Special Operations Forces (SOF) medic. Warm fresh whole blood transfusions could be a powerful tool for the SOF medic to use in order to begin hemostatic resuscitation in the field.

    Allogeneic blood transfusion during liver resection for malignancies has been associated with an increased incidence of different types of complications:infectious complications,tumor recurrence,decreased survival.Even if there is clear evidence of transfusion-induced immunosuppression,it is difficult to demonstrate that transfusion is the only determinant factor that decisively affects the outcome.In any case there are several motivations to reduce the practice of blood transfusion.The advantages and drawbacks of different transfusion alternatives are reviewed here,emphasizing that surgeons and anesthetists who practice in centers with a high volume of liver resections,should be familiar with all the possible alternatives.

    An accidental transfusion of hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) positive whole blood was given to a 19-yr-old male, bleeding after tonsillectomy. Serum obtained from the patient before the transfusion revealed no hepatitis B antigens or antibodies. After...... the transfusion the patient became HBsAg-positive, cleared this antigen and developed antibodies to both HBsAg and HBeAg. The transfusion blood was positive for total antibody and IgM antibody to hepatitis B core antigen (HBcAg). The patient's blood became positive for these antibodies after the transfusion...

    Thirty-seven fetuses with severe rhesus isoimmunization with a gestational age of less than 30 week underwent 92 intravascular transfusions. Of these, 77 were intracardiac, 13 umbilical vein and two umbilical artery transfusions. Procedure related complications occurred at eight (10%) intracardiac and at two (14%) umbilical cord transfusions. Reversal of hydrops was observed in 10 of 16 fetuses. The perinatal mortality among transfusion treated fetuses was 8/37 (21%). It is concluded that intravascular, intrauterine transfusion leads to improved results among fetuses with early onset of hydrops. Problems concerning indications and technique are discussed.

    Acute, nonvariceal upper gastrointestinal bleeding (UGIB) is a common medical emergency encountered worldwide. Despite medical and technological advances, it remains associated with significant morbidity and mortality. Rapid patient assessment and management are paramount. When indicated, upper endoscopy in patients presenting with acute UGIB is effective for both diagnosis of the bleeding site and provision of endoscopic hemostasis. Endoscopic hemostasis significantly reduces rebleeding rates, blood transfusion requirements, length of hospital stay, surgery, and mortality. Furthermore, early upper endoscopy, defined as being performed within 24 h of patient presentation, improves patient outcomes. A structured approach to the patient with acute UGIB that includes early hemodynamic resuscitation and stabilization, preendoscopic risk stratification using validated instruments, pharmacologic and endoscopic intervention, and postendoscopy therapy is important to optimize patient outcome and assure efficient use of medical resources.

    To compare the outcome of upper gastrointestinal bleeding (UGIB) between patients receiving restrictive and liberal transfusion. PubMed, EMBASE, and Cochrane Library databases were employed to identify all relevant randomized controlled trials regarding the outcome of UGIB after restrictive or liberal transfusion. Primary outcomes were death and rebleeding. Secondary outcomes were length of hospitalization, amount of blood transfused, and hematocrit and hemoglobin at discharge or after expansion. Overall, 4 papers were included in this meta-analysis. The incidence of death was significantly lower in patients receiving restrictive transfusion than those receiving liberal transfusion (OR: 0.52, 95%CI: 0.31-0.87, P = 0.01). The incidence of rebleeding was lower in patients receiving restrictive transfusion than those receiving liberal transfusion, but this difference did not reach any statistical significance (OR: 0.26, 95%CI: 0.03-2.10, P = 0.21). Compared with those receiving liberal transfusion, patients receiving restrictive transfusion had a significantly shorter length of hospitalization (standard mean difference: -0.17, 95%CI: -0.30--0.04, P = 0.009) and a significantly smaller amount of blood transfused (standard mean difference: -0.74, 95%CI: -1.15--0.32, P = 0.0005) with a lower hematocrit and hemoglobin level at discharge or after expansion. Restrictive transfusion should be employed in patients with UGIB.

    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 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.

    Full Text Available Life-long red blood transfusion remains the main treatment for severe thalassemia. The development of hemolytic alloantibodies and erythrocyte autoantibodies complicated transfusion therapy in thalassemia patients. The frequency causes and prevention of this phenomenon among 80 transfused thalassemia patients were evaluated in Ali Asghar Children's Hospital during 1998-2004 in a cross-sectional study. In our study the mean age at the initiation of transfusion was 1.7 years (SD = 1.94 and mean interval of transfusion 33.73 day (SD = 20.74. Autoimmunization in 15 patients was positive and 8 patients had hemolytic reaction in transfusion. Our data show that alloimmunization to minor erythrocyte antigens and erythrocyte autoimmunization of significant clinical variables, are frequent findings in transfused thalassemia patients. However data suggest that prevalence of immunization in our patients is less than other Asian countries.

    Full Text Available Acute spontaneous subdural hematoma in a patient of multiple myeloma receiving chemotherapy is an unknown event, needing an urgent neurosurgical management. We report this patient who presented with progressive neurological deterioration and a low platelet count. She was successfully managed by craniotomy and evacuation of subdural hematoma with intraoperative transfusion of platelets. The acute spontaneous subdural hematoma in her was probably related to the bleeding diathesis due to thrombocytopenia associated with chemotherapy.

    Schmuñis, G A

    1999-01-01

    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

    India has the highest prevalence of severe acute malnutrition (SAM). Severe anemia is one of the comorbidities responsible for increased mortality in severely malnourished children, yet it has not received the attention it should. The aim of the present study was to determine the prevalence and type of anemia and to evaluate the possible etiologies for severe anemia, in these children. A cross-sectional study of patients with SAM in a tertiary care hospital in northern India over a period of 12 mo from Sept. 1, 2010 to Aug. 31, 2011 was conducted. We observed the prevalence of severe anemia (hemoglobin anemia, number of patients requiring blood transfusion, hematologic profile of mothers, nature of feeding, duration of exclusive breastfeeding, and the demographic profile of these patients. Included in the study were 131 cases of SAM. The age group varied between 6 and to 59 mo. Of patients with SAM, 67.3% had severe anemia; 13.8% had moderate anemia. Of these patients, 25% required packed red blood cell transfusion. The most common type of anemia was microcytic (38.6%) followed by megaloblastic (30.5%). A high incidence of severe anemia in SAM with a large proportion (25%) requiring blood transfusion is a pointer toward nutritional anemia being a very common comorbidity of SAM requiring hospital admission. Because megaloblastic anemia closely followed microcytic anemia, supplementation with vitamin B12 in addition to iron and folic acid would be recommended. Copyright © 2014 Elsevier Inc.

  14. Post-transfusion purpura in an African-American man due to human platelet antigen-5b alloantibody: a case report

    Directory of Open Access Journals (Sweden)

    Lynce Filipa

    2012-12-01

    Full Text Available Abstract Introduction Post-transfusion purpura is a rare immunohematological disorder characterized by severe thrombocytopenia following transfusion of blood components and induced by an alloantibody against a donor platelet antigen. It occurs primarily in women sensitized by pregnancy and is most commonly caused by anti-human platelet antigen-1a antibodies. Here, we describe what we believe to be the first documented case of an African-American man who developed post-transfusion purpura due to an anti-human platelet antigen-5b alloantibody after receiving multiple blood products. Case presentation A 68-year-old African-American man initially admitted with atrial flutter was started on anticoagulation treatment, which was complicated by severe hematemesis. On days 4 and 5 of hospitalization, he received six units of packed red blood cells, and on days 4, 13 and 14 he received plasma. His platelet count began to drop on day 25 and on day 32 reached a nadir of 7 × 109/L. His platelet count increased after receiving intravenous immune globulin. An antibody with reactivity to human platelet antigen-5b was detected by a solid-phase enzyme-linked immunoassay. Our patient was homozygous for human platelet antigen-5a. Conclusion This case emphasizes the importance of including post-transfusion purpura in the differential diagnosis for both men and women with acute onset of thrombocytopenia following transfusion of blood products. The prompt recognition of this entity is crucial for initiation of the appropriate management.

    This study assessed the cost-effectiveness of Octaplas™ versus fresh frozen plasma (FFP) in patients receiving plasma transfusions in the United States (US). Acute and long-term complications of plasma transfusions were modelled in a decision tree followed by a Markov model, using a healthcare payer perspective. Over a lifetime time horizon, patients receiving Octaplas™ accumulate slightly more life years (0.00613 [95% uncertainty interval (95%UI): 0.00166-0.01561]) and quality-adjusted life years (QALY) (0.023 [95%UI: 0.012-0.044]) at lower cost compared with those treated with FFP. Octaplas™ demonstrated to be the dominant treatment option over FFP (95%UI: Dominant-US$ 15,764/QALY).

    The case of a 55-year-old man who attempted suicide by ingesting blue (10% after 29 hours).To remove the toxin, and because of the anuric acute renal failure, the patient received renal replacement therapy. Despite these therapeutic measures, the patient developed hemolytic anemia and disseminated intravascular coagulation, which were treated with red blood cell transfusion and intermittent hemodialysis. These interventions led to the improvement of his condition and the patient eventually fully recovered. Patient gave written informed consent.This is the third known case of chlorite poisoning that has been reported. Based upon this case, we suggest the management of sodium chlorite poisoning to comprise the early administration of methylene blue, in addition to renal replacement therapy and transfusion of red blood cells.

    2012-04-01

    Inherited hemoglobin-related disorders, which include the structural variants (hemoglobin S, C, and E) and the alpha (α)- and beta (β)-thalassemias, affect more than 300,000 children annually, particularly in malaria-endemic regions stretching from sub-Saharan Africa and the Mediterranean to Southeast Asia. Screening for carriers of these traits is important to provide prenatal genetic counseling and to accurately estimate the true prevalence and public health burden of these disorders. The clinical course of thalassemias, which affect nearly 70,000 children annually, is highly variable depending on the mixture of inherited alleles. The primary forms of non-transfusion-dependent thalassemia include β-thalassemia intermedia, hemoglobin E β-thalassemia, and hemoglobin H disease. Early clinical recognition of these disorders is essential to prevent affected children from being mistakenly placed on life-long transfusion therapy. Copyright © 2012 Elsevier Ltd.

    2000-09-16

    We have shown that it is possible to transmit bovine spongiform encephalopathy (BSE) to a sheep by transfusion with whole blood taken from another sheep during the symptom-free phase of an experimental BSE infection. BSE and variant Creutzfeldt-Jakob disease (vCJD) In human beings are caused by the same infectious agent, and the sheep-BSE experimental model has a similar pathogenesis to that of human vCJD. Although UK blood transfusions are leucodepleted--a possible protective measure against any risk from blood transmission--this report suggests that blood donated by symptom-free vCJD-infected human beings may represent a risk of spread of vCJD infection among the human population of the UK.

    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.

    Immunoglobulin transfusion is employed in the management of the failure of passive transfer (FPT). The aim of this study was to investigate the dose of immunoglobulin G (IgG) needed to reach a protective concentration (>10 g/L) in colostrum-deprived dairy calves. Twenty-eight Holstein Friesian newborn male calves were randomly assigned to either a control group (CG) or a treatment group (PG). Calves in the CG received 4 L of high quality colostrum within 12 h of birth. Calves in the PG received 62.7 ± 3.1 g of IgG IV in 2.6 ± 0.3 L of plasma within 6 h after birth. Serum immunoglobulin G (sIgG) and serum total protein (sTP) concentrations were assayed before and after (24 h, 72 h and 1 week after birth) plasma transfusion or colostrum ingestion. Serum (s) IgG and sTP concentrations increased in both groups throughout the period of observation. Mean sIgG and sTP concentrations after colostrum ingestion or plasma transfusion were higher in the CG than in the PG (P colostrum-deprived calves (>10 g/L). Calves in the CG had significantly lower morbidity and mortality rates compared to those in the PG, suggesting that plasma transfusion alone is ineffective in providing complete protection against neonatal disease.

    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.

    After a 4-year period in clinical practice the autologous transfusion concept Ulm (ATU) has proved its value. The effort and expense involved are entirely justified by obvious medical advantages. The patients' active involvement in the therapeutic procedure is a remarkable aspect of positive motivation. Furthermore, the medical staff is positively motivated, too, in spite of the obvious additional load to their daily routine work.

    Background and Study Objectives Transfusions are the primary therapy for thalassemia but have significant cumulative risks. In 2004, the Centers for Disease Control and Prevention (CDC) established a national blood safety monitoring program for thalassemia. The purpose of this report is to summarize the patient population as well as previous non-immune and immune transfusion complications at the time of enrollment into the program. A focus on factors associated with allo- and auto-immunization in chronically transfused patients and a description of blood product preparation and transfusion practices at the participating institutions are included. Study Design and Methods The CDC Thalassemia Blood Safety Network is a consortium of thalassemia centers, longitudinally following patients to determine transfusion-related complications. Enrollment occurred from 2004 through 2012 and annual data collection is ongoing. Demographic data, transfusion history, and previous transfusion and non-transfusion complications were summarized for patients enrolled between 2004 and 2011. Logistic analyses of factors associated with allo- and auto-immunization were developed. Summary statistics of infections reported at the time of enrollment were also calculated. Results The race/ethnicity of the 407 thalassemia patients enrolled in the Network was predominantly Asian or Caucasian and 27% were immigrants. The average age was 22.3 years ± 13.2 and patients received an average total number of 149 ± 103.4 units of red blood cells. Iron-induced multi-organ dysfunction was common despite chelation. At study entry, 86 patients had previously been exposed to possible transfusion-associated pathogens, including Hepatitis-C (61), Hepatitis B (20), Hepatitis A (3), Parvovirus (9), HIV (4), malaria (1), staphylococcus aureus (1) and babesia (1). As 27% of the population was born outside of the United States (India, Pakistan, Thailand, China, Vietnam and Iran accounting for 57%), the source of

    AIM: To evaluate the significance of autologous blood transfusion (AT) in reducing homologous blood trans-fusion (HT) in surgery for hepatocellular carcinoma (HCC).METHODS: The proportion of patients who received HT was compared between two groups determined by the time of AT introduction; period A (1991-1994, n = 93) and period B (1995-2000, n = 201). Multivariate logistic regression analysis was performed in order to identify independent significant predictors of the need for HT. We also investigated the impact of AT and HT on long-term postoperative outcome after curative sur-gery for HCC.RESULTS: The proportion of patients with HT was significantly lower in period B than period A (18.9% vs 60.2%, P < 0.0001). Multivariate logistic regression analysis identified AT administration as a significant independent predictor of the need for HT (P < 0.0001). Disease-free survival in patients with AT was com-parable to that without any transfusion. Multivariate analysis identified HT administration as an independent significant factor for poorer disease-free survival (P = 0.0380).CONCLUSION: AT administration significantly de-creased the need for HT. Considering the postoperative survival disadvantage of HT, AT administration could improve the long-term outcome of HCC patients.

    Blood is donated either as whole blood, with subsequent component processing, or through the use of apheresis devices that extract one or more components and return the rest of the donation to the donor. Blood component therapy supplanted whole blood transfusion in industrialized countries in the middle of the twentieth century and remains the standard of care for the majority of patients receiving a transfusion. Traditionally, blood has been processed into three main blood products: red blood cell concentrates; platelet concentrates; and transfusable plasma. Ensuring that these products are of high quality and that they deliver their intended benefits to patients throughout their shelf-life is a complex task. Further complexity has been added with the development of products stored under nonstandard conditions or subjected to additional manufacturing steps (e.g., cryopreserved platelets, irradiated red cells, and lyophilized plasma). Here we review established and emerging methodologies for assessing blood product quality and address controversies and uncertainties in this thriving and active field of investigation.

    2013-04-01

    This article presents thromboelastography (TEG) as an important assay to incorporate into anesthesia practice for development of evidence-based therapy of trauma patients receiving blood transfusions. The leading cause of death worldwide results from trauma. Hemorrhage is responsible for 30% to 40% of trauma mortality and accounts for almost 50% of the deaths occurring in the initial 24 hours following the traumatic incident. On admission, 25% to 35% of trauma patients present with coagulopathy, which is associated with a sevenfold increase in morbidity and mortality. The literature supports that routine plasma-based routine coagulation tests, such as prothrombin time, activated partial thromboplastin time, and international normalized ratio, are inadequate for monitoring coagulopathy and guided transfusion therapy in trauma patients. A potential solution is incorporating the use of the TEG assay into the care of trauma patients to render evidence-based therapy for patients requiring massive blood transfusions. Analysis with TEG provides a complete picture of hemostasis, which is far superior to isolated, static conventional tests. The result is a fast, well-designed, and precise diagnosis enabling more cost-effective treatment, improved clinical outcome, accurate use of blood products, and pharmaceutical therapies at the point of care.

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

    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.

    Platelet production rates were studied in hypoxic, red blood cell (RBC) transfused, and normal mice. In addition, platelet depletion was induced in some of the mice by injection of rabbit anti-mouse platelet serum (RAMPS) to stimulate platelet production. Hypoxia alone caused an increase in haematocrit and platelet count at 1 to 3 d, followed by a decrease in platelet counts to below normal values at 6 to 7 d. On the other hand, RBC transfusion caused increased haematocrit and decreased platelet count of mice at 1 to 4 d, with a return of platelet counts to normal by 5 to 6 d. Normal mice and mice transfused with RBC responded to platelet depletion with rebound-thrombocytosis with maximum platelet production 3 to 5 d later and elevated platelet counts on day 5 to 6. However, platelet production in platelet-depleted mice exposed to hypoxia was less marked, and platelet counts did not reach normal levels. The data are consistent with the hypothesis that hypoxia causes thrombocytopenia by stem cell competition between erythroid and megakaryocytic cell lines and/or inhibition of thrombopoietin production.

    A survey has been made of the results of 12 months' VDRL screening in a blood transfusion service. Positive VDRL tests were found on 318 of the 73 350 blood donations collected during 1974. Thirty-four tests confirming specific treponemal infection were found in 24 donors. A battery of confirmatory tests showed the remaining 284 positive VDRL reactions from 235 donors to be biological false positive (BFP) results, and, of these, one-third were considered entirely negative by the reference laboratory. BFP reactions were commoner in female donors than in males, and a higher incidence than expected was observed in younger female donors and older male donors. A marked seasonal incidence was noted, 65% of all BFP tests from the transfusion service being found in the four colder months of May to August. Although some differences exist between the group as a whole and the 36 donors (15.3%) found to have BFP results on more than one occasion during the year, there is little evidence from these studies to suggest that regular blood donation per se is a contributing factor to the finding of a BFP result in VDRL screening. It is probable that the population tested regularly by the blood transfusion service reflects a small but representative sample of the community as a whole.

    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.

  1. Bilaterally Symmetrical Lower Extremity Compartment Syndrome following Massive Transfusion

    Full Text Available Compartment syndrome is a serious condition characterized by raised intracompartmental pressure, which develops following trauma. Well leg compartment syndrome (WLCS is a term reserved for compartment syndrome in a nontraumatic setting, usually resulting from prolonged lithotomy position during surgery. In literature, 8 cases have been reported regarding well leg compartment syndrome in a supine position and bilateral symmetrical involvement was observed in only 2 cases. In WLCS etiology, lengthy surgery, lengthy hypotension, and extremity malpositioning have been held responsible but one of the factors with a role in the etiology may have been the tissue oedema and impaired microcirculation formed from the effect of vasoactive mediators expressed into the circulation associated with the massive blood transfusion. The case is presented here regarding symmetrical lower extremity compartment syndrome after surgery in which massive transfusion was made for gross haemorrhage from an abdominal injury. In conclusion, blood transfusion applied at the required time is life-saving but potential risks must always be considered.

    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.

  3. Transfusion in transplant patients: the good, the bad, and the ugly.

    Several transfusion-related complications have particular relevance to the transplant setting. Transfusions reportedly improve solid organ graft survival, especially when the donor and recipient share at least one HLA-DR antigen. Whereas the mechanism for this effect is unclear, less favorable "immunomodulating" effects of transfusion may increase postoperative infections and shorten survival time and disease-free intervals in patients with a variety of malignancies who are undergoing surgery. The contribution of the different components of the blood transfusion to these outcomes remains speculative. Directed donations, especially from relatives and in the setting of a recipient who is immunosuppressed, may give rise to a severe but under-appreciated immunologic consequence of transfusion: graft-versus-host disease. Although still rarely reported, transfusional graft-versus-host disease is almost invariably fatal. This complication is entirely avoidable if the transfused blood product is appropriately gamma-irradiated. Infectious complications remain the most feared consequence of transfusion; the cytomegalovirus, the human immunodeficiency virus, and hepatitis B and C may run a more fulminant course in transplant patients who are immunosuppressed. Red cell substitutes, hematopoietic growth factors, and autologous transfusion are among the strategies for preventing complications of blood transfusion. With the advent of cyclosporine and more potent and specific immunosuppressive therapies, the desirability of preoperative transfusion for organ grafts warrants reevaluation.

    Transfusions are the primary therapy for thalassemia but have significant cumulative risks. In 2004, the Centers for Disease Control and Prevention (CDC) established a national blood safety monitoring program for thalassemia. This report summarizes the population and their previous nonimmune and immune transfusion complications. The CDC Thalassemia Blood Safety Network is a consortium of centers longitudinally following patients. Enrollment occurred from 2004 through 2012. Demographics, transfusion history, infectious exposures, and transfusion and nontransfusion complications were summarized. Logistic regression analyses of factors associated with allo- and autoimmunization were employed. The race/ethnicity of these 407 thalassemia patients was predominantly Asian or Caucasian. The mean ± SD age was 22.3 ± 13.2 years and patients had received a mean ± SD total number of 149 ± 103.4 units of red blood cells (RBCs). Multiorgan dysfunction was common despite chelation. Twenty-four percent of transfused patients had previous exposure to possible transfusion-associated pathogens including one case of babesia. As 27% were immigrants, the infection source cannot be unequivocally linked to transfusion. Transfusion reactions occurred in 48%, including allergic, febrile, and hemolytic; 19% were alloimmunized. Common antigens were E, Kell, and C. Years of transfusion was the strongest predictor of alloimmunization. Autoantibodies occurred in 6.5% and were associated with alloimmunization (p thalassemia. New pathogens were noted. National guidelines for RBC phenotyping and preparation are needed to decrease transfusion-related morbidity. © 2013 American Association of Blood Banks.

    2009-01-01

    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.

    Incidence of acute kidney injury (AKI) in adult trauma patients is 18% with 70% requiring renal replacement therapy. It is a challenge to treat AKI with coagulopathy since there are no defined transfusion triggers for these patients. We report a case wherein a polytrauma patient developed AKI for which he/she was dialysed and subsequently had an intracerebral bleed. There is a need to develop guidelines to transfusion triggers in AKI patients keeping vigilance on fluid overload, hyperkalemia and uraemia-induced platelet dysfunction. PMID:25885629

Materials and Methods: Basal serum concentrations of FSH, LH, and T and semen parameters were evaluated before and 7 days after PCTx in 18 young adults with transfusion-dependent SCD, aged 20.7 ± 2.88 years. They had full pubertal development (Tanner′s stage 5, and capacity to ejaculate. They were regularly transfused since early childhood. Chelation therapy was started early during the first 2 years of life using desferrioxamine and was replaced by deferasirox for the last 4-5 years. Ten patients were on TTx and eight were on ETx regimen. Results: PCTx significantly increased hemoglobin (Hb from 8.5 ± 1.17 g/dl to 10.5 ± 0.4 g/dl, T from 12.3 ± 1.24 nmol/L to 14.23 ± 1.22 nmol/L and gonadotropins′ concentrations. Sperm parameters improved significantly after PCTx including: total sperm count from 87.4 ± 24.6 million/ml to 146.2 ± 51.25 million/ml, total progressive sperm motility (TPM from 40.8 ± 11.1 million/ml to 93.4 ± 38.3 million/ml, rapid progressive sperm motility (RPM progressive motility from 29.26 ± 8.75 million/ml to 67.4 ± 29 million/ml. After PCTx the total sperm count, TPM and RPM were significantly better in the ETx group versus the TTx group. Before and after PCTx, T concentrations were correlated significantly with sperm total count, volume, TPM and RPM (r = 0.53, 0.55, 0.42, and 0.38, respectively, P < 0.01. Hb concentrations were correlated significantly with sperm count, TPM, RPM, and % of sperms with normal morphology (r = 0.60, 0.69, 0.66, and 0.86, respectively, P < 0.001. Conclusion: Our study suggests that in males with SCD blood transfusion is associated

    To investigate the potential additive effects of blood transfusion and sepsis on colon cancer disease-specific survival, cardiovascular disease-specific survival, and overall survival after colon cancer surgery. Perioperative blood transfusions are associated with infectious complications and increased risk of cancer recurrence through systemic inflammatory effects. Furthermore, recent studies have suggested an association among sepsis, subsequent systemic inflammation, and adverse cardiovascular outcomes. However, no study has investigated the association among transfusion, sepsis, and disease-specific survival in postoperative patients. The New York State Cancer Registry and Statewide Planning and Research Cooperative System were queried for stage I to III colon cancer resections from 2004 to 2011. Propensity-adjusted survival analyses assessed the association of perioperative allogeneic blood transfusion, sepsis, and 5-year colon cancer disease-specific survival, cardiovascular disease-specific survival, and overall survival. Among 24,230 patients, 29% received a transfusion and 4% developed sepsis. After risk adjustment, transfusion and sepsis were associated with worse colon cancer disease-specific survival [(+)transfusion: hazard ratio (HR) 1.19, 95% confidence interval (CI) 1.09-1.30; (+)sepsis: HR 1.84, 95% CI 1.44-2.35; (+)transfusion/(+)sepsis: HR 2.27, 95% CI 1.87-2.76], cardiovascular disease-specific survival [(+)transfusion: HR 1.18, 95% CI 1.04-1.33; (+)sepsis: HR 1.63, 95% CI 1.14-2.31; (+)transfusion/(+)sepsis: HR 2.04, 95% CI 1.58-2.63], and overall survival [(+)transfusion: HR 1.21, 95% CI 1.14-1.29; (+)sepsis: HR 1.76, 95% CI 1.48-2.09; (+)transfusion/(+)sepsis: HR 2.36, 95% CI 2.07-2.68] relative to (-)transfusion/(-)sepsis. Additional analyses suggested an additive effect with those who both received a blood transfusion and developed sepsis having even worse survival. Perioperative blood transfusions are associated with shorter survival

    Full Text Available We report a case of transient hyperkalemia during hysterectomy after cesarean section, due to preoperatively undiagnosed placenta accreta that caused unforeseen massive hemorrhage and required rapid red cell transfusion. Hyperkalemia-induced by rapid red cell transfusion is a well-known severe complication of transfusion; however, in patients with sudden massive hemorrhage, rapid red cell transfusion is necessary to save their life. In such cases, it is extremely important to monitor serum potassium levels. For an emergency situation, a system should be developed to ensure sufficient preparation for immediate transfusion and laboratory tests. Furthermore, sufficient stock of preparations to treat hyperkalemia, such as calcium preparations, diuretics, glucose, and insulin is required. Moreover, a transfusion filter that absorbs potassium has been developed and is now available for clinical use in Japan. The filter is easy to use and beneficial, and should be prepared when it is available.

    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.

  13. Real-time blood cross-matching sensor for intelligent management of transfusion safety.

    Blood transfusion errors are not uncommon. In some cases the error is fatal. This is primarily due to lack of an automated system at the point of application and over-reliance on bar-coding and paperwork to catch these critical errors. In emergency situations, human errors contribute to transfusion and transplantation of incompatible blood types and organs resulting in rejection and possible fatality. We present a sensing concept that will monitor blood compatibility between the patient and the transfusion bag before allowing the valve to open for transfusion to take place. This will eliminate all transfusion errors and provide 100% safe transfusions automatically. The operating principle of the sensor is based on the light scattering characteristics of dilute blood and the effect of agglutination on scattering. The device proposed is an optical system based on spectrophotometric methods. The device configuration, and results from several tests with combinations of known blood samples will be presented.

  14. Consequences of Transfusing Blood Components in Patients With Trauma: A Conceptual Model.

    Jones, Allison R; Frazier, Susan K

    2017-04-01

    Transfusion of blood components is often required in resuscitation of patients with major trauma. Packed red blood cells and platelets break down and undergo chemical changes during storage (known as the storage lesion) that lead to an inflammatory response once the blood components are transfused to patients. Although some evidence supports a detrimental association between transfusion and a patient's outcome, the mechanisms connecting transfusion of stored components to outcomes remain unclear. The purpose of this review is to provide critical care nurses with a conceptual model to facilitate understanding of the relationship between the storage lesion and patients' outcomes after trauma; outcomes related to trauma, hemorrhage, and blood component transfusion are grouped according to those occurring in the short-term (≤30 days) and the long-term (>30 days). Complete understanding of these clinical implications is critical for practitioners in evaluating and treating patients given transfusions after traumatic injury.

    Perioperative patient optimization can minimize the need for blood transfusions in patients undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA). The purpose of this study was to determine predictors and complications of transfusions. This retrospective review analyzed 1795 patients who underwent primary THA and TKA at our institution between January 2011 and December 2012. Of the 1573 patients ultimately included the rates of transfusion were 9.27% in TKA and 26.6% in THA. Significant predictors for transfusion include: preoperative hemoglobin, age, female gender, body mass index, creatinine, TKA, operating room time, operative blood loss, and intra-operative fluids. The DVT rate was comparable, but deep surgical site infection rate among transfused patients was 2.4% compared to 0.5% in non-transfused patients (P = 0.0065).

    The need for physicians and technical consultants specialized in transfusion medicine is urgent in China, as there are 20 000 hospitals and 500 blood centers in need of staff with this expertise. The progress made in transfusion medicine as a specialty has been relatively slow in China. Current Chinese medical education and service systems have not developed transfusion medicine as a stand-alone medical specialty. Most physicians receive only minimal training in transfusion medicine in medical school. This training is usually integrated into surgical training and addresses the most common technologies. In 2008, a 5-year bachelor's diploma program in transfusion medicine was established as an undergraduate specialty in Southern Medical University, Guangzhou, China. This article intends to summarize the 8 years of experience educating undergraduates in the specialty of transfusion medicine.

    Blood transfusion services have achieved newer heights in the last decade, with developments in cellular techniques, component separation, and integration of molecular methods. However, the system of recording and reporting of the adverse events related to blood transfusion is developing countries like India is grossly inadequate and voluntary in nature. This study was undertaken to analyze the retrospective data on adverse events related to blood transfusions in our hospital. This retrospective study was done to examine all the transfusion related adverse events reported in a Regional Blood Bank Transfusion Centre of North India over a period of 9 years. Adverse transfusion events related to whole blood, red cell concentrates (RCCs), and all other components were analyzed and classified on the basis of their clinical features and laboratory tests. Average rate of transfusion reactions with the components was also assessed. Categorical variables were analyzed using the Chi-square test. P < 0.05 was taken to indicate a significant difference. During this period, a total of 1,60,973 blood/blood component units were issued by our blood bank to various departments of the hospital and 314 immediate transfusion events were reported. The rate of immediate transfusion reactions during the study was 0.19%. Average transfusion reaction rate with RCC was 0.25% with febrile nonhemolytic reactions being the most common type of adverse event (37.2%). Awareness should be increased among clinicians to correctly prevent, identify, and report transfusion-related adverse events. These measures should be implemented to increase blood transfusion quality and safety.

  19. Role of platelet transfusion in children with bleeding in dengue fever

    2015-01-01

    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.

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

    Directory of Open Access Journals (Sweden)

    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.

    Full Text Available 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.

    Critically ill patients frequently receive plasma transfusion under the assumptions that abnormal coagulation test results confer increased risk of bleeding and that plasma transfusion will decrease this risk. However, the effect of prophylactic plasma transfusion remains poorly understood. The objective of this study was to determine the relationship between prophylactic plasma transfusion and bleeding complications in critically ill patients. This is a retrospective cohort study of adults admitted to the intensive care unit (ICU) at a single academic institution between January 1, 2009 and December 31, 2013. Inclusion criteria included age ≥18 years and an international normalized ratio measured during ICU admission. Multivariable propensity-matched analyses were used to evaluate associations between prophylactic plasma transfusion and outcomes of interest with a primary outcome of red blood cell transfusion in the ensuing 24 hours and secondary outcomes of hospital- and ICU-free days and mortality within 30 days of ICU discharge. A total of 27,561 patients were included in the investigation with 2472 (9.0%) receiving plasma therapy and 1105 (44.7%) for which plasma transfusion was prophylactic in nature. In multivariable propensity-matched analyses, patients receiving plasma had higher rates of red blood cell transfusion (odds ratio: 4.3 [95% confidence interval: 3.3-5.7], P plasma in the critically ill was not associated with improved clinical outcomes. Further investigation examining the utility of plasma transfusion in this population is warranted.

    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.

    Very-low-birthweight infants are among the most heavily transfused patients. The objective of this study was to verify if the introduction of a strict guideline would reduce the need for red blood cell transfusions in the first 4 weeks of life in these neonates. This was a multicentre prospective study of two cohorts of very-low-birthweight infants transfused in accordance with the recommendations of a neonatologist (Phase 1) or according to previously published guidelines (Phase 2). In the first 28 days of life, 102 patients (68.5%) in Phase 1 and 117 (59.7%) in Phase 2 were transfused. The number of transfusions was 1.9 +/- 2.0 in Phase 1 and 1.4 +/- 1.6 in Phase 2 (P = 0.01). After adjusting for gestational age, blood loss and the presence of respiratory distress syndrome, the strict guideline reduced the number of transfusions in 17.6% (IC 95%-30.5% to -2.6%). The strict guideline was effective in reducing erythrocyte transfusions in very-low-birthweight infants.

    A National Register of transfusion-transmitted infections was opened by the French Society of Blood Transfusion on 1 October, 1986. Out of 54 initially reported cases of HIV-infection, allegedly transmitted by blood components, further investigation could be completed in 33 cases. The transfusional origin of contamination was considered as established or probable in 28/33 cases, either because a potentially infectious unit was identified among those transfused to the recipient (23/28), or because the recipient was known to be seronegative before transfusion (5/28), or both (10/28). In 5/33 cases transfusion was considered as presumably responsible for contamination because no other risk factor was found in the recipient. Among the 33 documented cases of HIV-transmission by screened blood, 29 (88%) occurred between 1985 and 1987, and four (12%) during 1988. Out of 19 implicated donors later found seropositive, 16 belonged to a high-risk group for HIV-infection. The majority of HIV-infections occurred as a consequence of blood donation in the window period between contamination and the appearance of detectable antibodies in the donor's serum (11/19). In three instances, however, human and operational errors led to the release of seropositive units. We conclude that the main value of this Register is to provide a potential trend-indicator of transfusion-related infectious risks, to allow objective documentation of reported cases and to contribute to the improvement of blood transfusion practice.

    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. 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. 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. 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.

    Full Text Available Legal issues play a vital role in providing a framework for the Indian blood transfusion service (BTS, while ethical issues pave the way for quality. Despite licensing of all blood banks, failure to revamp the Drugs and Cosmetic Act (D and C Act is impeding quality. Newer techniques like chemiluminescence or nucleic acid testing (NAT find no mention in the D and C Act. Specialised products like pooled platelet concentrates or modified whole blood, therapeutic procedures like erythropheresis, plasma exchange, stem cell collection and processing technologies like leukoreduction and irradiation are not a part of the D and C Act. A highly fragmented BTS comprising of over 2500 blood banks, coupled with a slow and tedious process of dual licensing (state and centre is a hindrance to smooth functioning of blood banks. Small size of blood banks compromises blood safety. New blood banks are opened in India by hospitals to meet requirements of insurance providers or by medical colleges as this a Medical Council of India (MCI requirement. Hospital based blood banks opt for replacement donation as they are barred by law from holding camps. Demand for fresh blood, lack of components, and lack of guidelines for safe transfusion leads to continued abuse of blood. Differential pricing of blood components is difficult to explain scientifically or ethically. Accreditation of blood banks along with establishment of regional testing centres could pave the way to blood safety. National Aids Control Organisation (NACO and National Blood Transfusion Council (NBTC deserve a more proactive role in the licensing process. The Food and Drug Administration (FDA needs to clarify that procedures or tests meant for enhancement of blood safety are not illegal.

    It is not uncommon in transfusion practice to see blood/components with abnormal colored plasma. The present study was conducted to identify and determine the etiology of blood and/or blood components showing altered color. The present study was conducted in the Department of Transfusion Medicine, Government Medical College and Hospital, Chandigarh over a period of seven months. All the blood units/components having an abnormal appearance were segregated as: 1. Green discoloration. 2. Yellow discoloration. 3. Bright cherry red color. 4. Lipemic plasma. The donor's history was carefully evaluated and relevant investigations were done depending on discoloration. Seventeen units out of 7370 (0.23%) donations showed discoloration. In 3 units the plasma was green, 5 units were yellow, in 3 units PRBC/WB unit was bright cherry red and in the remaining 6 units the plasma was lipemic. Total bilirubin of all the 5 donors with yellowish plasma ranged from 1.6 to 2.3mg/dl. The hemoglobin and hematocrit of two out of three donors with cherry red discoloration of PRBC/WB was low. All the donors with lipemic plasma gave history of intake of fatty meal prior to donating blood. The existing rules prohibit issue of blood and blood components if the plasma is abnormal in color. Our study showed that many of the discolored units could have been safely transfused but further larger studies are required to confirm the safety of recipients receiving such units.

    Full Text Available Aims: The aim of this study was to assess ocular changes in thalassemia patients who have received multiple transfusions and chelate binding therapy in order to avoid iron accumulation. Settings and Design: A cross-sectional study. Subjects and Methods: A total of 54 thalassemia major patients were selected as case group, and 54 age- and sex-matched healthy subjects were regarded as a control group. Ocular examination included visual acuity, refraction testing, slit lamp examination, funduscopy, tonometry, perimetry, tear break-up time test, and color vision testing were performed for all the participants. We computed the frequency and duration of blood transfusion, the mean serum ferritin level, pretransfusion hemoglobin concentration, and type, duration, and daily dose of chelation therapy for thalassemia patients based on their records. Statistical Analysis Used: All data analysis was performed using SPSS, version 19. Results: All the thalassemic patients were asymptomatic, but abnormal ocular findings (dry eye (33.3%, cataract (10.2%, retinal pigment epithelium degeneration (16.7%, color vision deficiency (3.7%, and visual field defects (33.7% were seen in 68.5% of thalassemic group. The prevalence of ocular abnormalities in normal group was 19.4%, which was significantly lower than that in thalassemia patients (P = 0.000. No significant correlation was found between ocular abnormalities and mean serum ferritin level (P = 0.627 and mean hemoglobin concentration (P = 0.143. Correlation of number of blood transfusion with the presence of ocular abnormalities was found to be statistically significant (P = 0.005. Conclusions: As life expectancy for beta-thalassemia patients extends, regular ophthalmological evaluation to detect early changes in their ocular system is recommended.

    Early recognition and treatment of trauma patients requiring massive transfusion (MT) has been shown to reduce mortality. While many risk factors predicting MT have been demonstrated, there is no universally accepted method or algorithm to identify these patients. We hypothesised that even among experienced trauma surgeons, the clinical gestalt of identifying patients who will require MT is unreliable. Transfusion and mortality outcomes after trauma were observed at 10 U.S. Level-1 trauma centres in patients who survived ≥ 30 min after admission and received ≥ 1 unit of RBC within 6h of arrival. Subjects who received ≥ 10 units within 24h of admission were classified as MT patients. Trauma surgeons were asked the clinical gestalt question "Is the patient likely to be massively transfused?" 10 min after the patients arrival. The performance of clinical gestalt to predict MT was assessed using chi-square tests and ROC analysis to compare gestalt to previously described scoring systems. Of the 1245 patients enrolled, 966 met inclusion criteria and 221 (23%) patients received MT. 415 (43%) were predicted to have a MT and 551(57%) were predicted to not have MT. Patients predicted to have MT were younger, more often sustained penetrating trauma, had higher ISS scores, higher heart rates, and lower systolic blood pressures (all pGestalt sensitivity was 65.6% and specificity was 63.8%. PPV and NPV were 34.9% and 86.2% respectively. Data from this large multicenter trial demonstrates that predicting the need for MT continues to be a challenge. Because of the increased mortality associated with delayed therapy, a more reliable algorithm is needed to identify and treat these severely injured patients earlier. Copyright © 2015 Elsevier Ltd.

    Full Text Available The provision of health services should be carried attached to the scientific and ethical principles of medicine. The negative to accept blood transfusion by Jehovah's Witnesses, when indicated, determines a conflict and a challenge for physicians. We discuss concepts related to this complex situation, including: Freedom of religion and belief, patients’ rights, regulatory framework that applies to providers of health services and medical rights. Which should be taken into account in these situations to make an informed decision from the legal and ethical point of view.

    A transfusion-associated hepatitis A outbreak was found in the first time in Hungary. The outbreak involved five cases. Parenteral transmission of hepatitis A is rare, but may occur during viraemia. Direct sequencing of nested PCR products was performed, and all the examined samples were identical in the VP1/2A region of the hepatitis A virus genome. HAV sequences found in recent years were compared and phylogenetic analysis showed that the strain which caused these cases is the same as that had spread in Hungary recently causing several hepatitis A outbreaks throughout the country.

    The risk of hepatitis B virus (HBV) transmission by transfusion is higher than that of other blood-borne viruses. In France, before the introduction of HBV nucleic acid testing (NAT) in 2010, blood donations were tested for hepatitis B surface antigen (HBsAg) and antibodies against hepatitis B core antigen, and the residual risk of HBV transfusion related to preseroconversion acute phase was estimated at 0.54 per million donations. The additional value of the implementation of a highly sensitive HBV NAT to prevent such transmissions is discussed. Two lookback investigations based on HBV seroconversion of repeat donors were performed. Donors and recipients were followed up in multiple samples that were tested for HBV serologic and molecular markers. The recipients have shown posttransfusion HBsAg seroconversion. The archived samples from the implicated donations were positive for HBV DNA at extremely low viral load in both cases. HBV isolates from donors and recipients of each case were organized in the same cluster with 100% identities into Genotypes A2 and B4, respectively. One recipient spontaneously recovered from infection while the second was successfully treated. The present cases highlight the importance of introducing highly sensitive HBV NAT to prevent transmission. Moreover, the lookback studies based on appropriate molecular and serologic investigations of patients transfused with previous donations from newly identified HBV-infected repeat donors offer the opportunity to treat a recently infected recipient. © 2012 American Association of Blood Banks.

    This study was aimed to analyze the serological characteristics, efficacy and safety of incompatible RBC transfusion in patients with autoimmune hemolytic anemia (AIHA). The patients with idiopathic or secondary AIHA were analyzed retrospectively, then the serological characteristics and the incidence of adverse transfusion reactions were investigated, and the efficacy and safety of incompatible RBC transfusion were evaluated according to the different autoantibody type and infused different RBC components. The results showed that out of 61 cases of AIHA, 21 cases were idiopathic, and 40 cases were secondary. 8 cases (13.1%) had IgM cold autoantibody, 50 cases (82.0%) had IgG warm autoantibody, and 3 cases (4.9%) had IgM and IgG autoantibodies simultaneously. There were 18 cases (29.5%) combined with alloantibodies. After the exclusion of alloantibodies interference, 113 incompatible RBC transfusions were performed for 36 patients with AIHA, total efficiency rate, total partial efficiency rate and total inefficiency rate were 56.6%, 15.1% and 28.3%, respectively. Incompatible RBC transfusions were divided into non-washed RBC group and washed RBC group. The efficiency rate, partial efficiency rate and inefficiency rate in non-washed RBC group were 57.6%, 13.0% and 29.4%, respectively. The efficiency rate, partial efficiency rate and inefficiency rate in washed RBC group were 53.6%, 21.4% and 25.0%, respectively. There was no significant difference of transfusion efficacy (P > 0.05) in two groups. Incompatible RBC transfusions were also divided into IgM cold autoantibody group and IgG warm autoantibody group. The efficiency rate, partial efficiency rate and inefficiency rate in IgM cold autoantibody group were 46.2%, 30.8% and 29.4%, respectively. The efficiency rate, partial efficiency rate and inefficiency rate in IgG warm autoantibody group were 56.7%, 13.4% and 29.9%, respectively.

    To examine outcomes in patients who receive small amounts of intraoperative blood transfusion. Longitudinal, uncontrolled observational study evaluating results of intraoperative transfusion in patients entered into the American College of Surgeons National Surgical Quality Improvement Program database. We made propensity-matched comparisons between patients who received and did not receive intraoperative transfusion to minimize confounding when estimating the effect of intraoperative transfusion on postoperative outcomes. We queried the American College of Surgeons National Surgical Quality Improvement Program database for patients undergoing operations between January 1, 2005, and December 31, 2009. A large sample of surgical patients from 173 hospitals throughout the United States. Operative mortality and serious perioperative morbidity (≥1 of 20 complications). After exclusions, 941,496 operations were analyzed in patients from 173 hospitals. Most patients (893,205 patients [94.9%]) did not receive intraoperative transfusions. Patients who received intraoperative infusion of 1 unit of packed red blood cells (15,186 patients [1.6%]) had higher unadjusted rates of mortality and more serious morbidity. These rates further increased with intraoperative transfusion of more than 1 unit of packed red blood cells in a dose-dependent manner. After propensity matching to adjust for multiple preoperative risks, transfusion of a single unit of packed red blood cells increased the multivariate risk of mortality, wound problems, pulmonary complications, postoperative renal dysfunction, systemic sepsis, composite morbidity, and postoperative length of stay compared with propensity-matched patients who did not receive intraoperative transfusion. There is a dose-dependent adverse effect of intraoperative blood transfusion. It is likely that a small, possibly discretionary amount of intraoperative transfusion leads to increased mortality, morbidity, and resource use

    Treating the precipitating factors of delirium is the mainstay of the prevention and treatment of delirium. We aim to investigate the role of anemia and blood transfusion within the multicomponent prevention and treatment strategy of delirium. Systematic review. We included cohort studies or Randomized Controlled Trials (RCTs) that considered blood transfusion as treatment for delirium or risk factor, and had delirium as outcome. Hospitalized patients above 55 years old. We searched MEDLINE from 1946 through November 2014. Quality assessment and data extraction were performed systematically. We included 23 studies (n = 29,471). The majority of the studies (n = 22) had a limited quality and for one study quality was uncertain. Two studies evaluated the association between transfusion strategy and postoperative delirium and found no association. Twenty-one studies investigated blood transfusion as a risk factor for delirium. In four of the 21 studies it could be assumed that delirium occurred after transfusion. One of these studies stated that transfusion was a significant risk factor for subsequent delirium (odds ratio (OR) = 3.68, 95% confidence interval (CI) = 1.32-10.94). The other three studies found no association between transfusion and delirium. In the remaining 17 studies, it was not clear whether delirium occurred before or after transfusion, so no conclusion could be drawn on the role of transfusion in delirium development. The majority of the included studies was not suited to answer the research question properly as the time course of the beginning of delirium as to transfusion was lacking. Our review shows that there is no good quality evidence available for blood transfusion to be a risk factor for delirium or to be a preventive or treatment option. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

    'Starry sky' liver is one of the most common sonographic patterns in diffuse liver disease. It is characterized by clearly identified portal venules due to diminished parenchymal echogenicity. In advanced cases of twin-to-twin transfusion syndrome (TTTS), volume overload is considered the key factor in the pathogenesis of cardiac dysfunction of the recipient twin. When right-sided failure occurs, the liver might show signs of edema and, as in acute hepatitis, the appearance of starry sky might develop. We present a case in which the sonographic appearance of starry sky liver, along with right-sided cardiac failure (tricuspid regurgitation), were the first signs of TTTS in monochorionic twins at 20 weeks. A short time later, at 21 weeks, other signs of overload and signs of worsening heart failure were noted, as the typical triphasic waves in the inferior vena cava were replaced by a biphasic flow profile. Twin 2 at that time had relative oligohydramnios. A few days later, relative polyhydramnios and edema of the placental domain of the recipient twin were also noted. To the best of our knowledge, this is the first case report describing this hepatic sonographic pattern as an early sonographic sign of TTTS.

    Full Text Available Dengue viruses (DENV 1–4 are a risk to transfusion safety, with several transfusion-transmitted (TT cases reported globally. DENV 1–4 are endemic in over 100 countries, with seasonal outbreaks occurring in northeastern Australia. To mitigate TT-DENV risk in Australia, fresh blood components are not manufactured from donors returning from any area (domestic/overseas with known dengue transmission. Alternatively, TT-DENV risk may be mitigated using an appropriate blood donor screening assay. We aimed to determine the rate of dengue infection in donors during dengue outbreaks in Australia. Plasma samples were collected from blood donors during local dengue outbreaks. All samples were tested for the presence of DENV RNA and selected samples were tested for DENV antigen (nonstructural protein 1, NS1 with two assays. No donors residing in high risk areas had detectable levels of DENV RNA or NS1 and no cases of DENV viremia were detected in blood donors residing in areas of Australia experiencing DENV outbreaks. Definitive conclusions could not be drawn from this study; however, the lack of detection of DENV RNA or antigen in donations suggests that the current risk of TT-DENV is low and maintaining the fresh component restriction for “at-risk” donors is appropriate.

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

    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.

    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.

  7. Transfusion practice in major obstetric haemorrhage: lessons from trauma.

    2012-01-01

    The management of massive haemorrhage with blood products is changing as evidence arrives from civilian and military trauma. Rapid early replacement of coagulation factors and platelets is now becoming central to improving outcome, usually given in higher ratios with respect to red cell units than previously recommended and using empiric transfusion based on clinical rather than laboratory parameters. The management of three cases of major obstetric haemorrhage based on these principles is presented. Packed red blood cells, fresh frozen plasma, platelets and cryoprecipitate were transfused in the ratios 5:2:2:1, 4.5:1:1:1 and 4.5:2:1:1. Each patient had acceptable full blood count and coagulation results after surgery and all made an uneventful recovery. These outcomes support the opinion that major obstetric haemorrhage can be managed in a similar fashion to blood loss in trauma. Recommendations from the Association of Anaesthetists of Great Britain and Ireland, and the UK National Patient Safety Agency should be considered during major obstetric haemorrhage.

  8. Transfusion Strategy: Impact of Haemodynamics and the Challenge of Haemodilution

    2014-01-01

    Full Text Available Blood transfusion is associated with increased morbidity and mortality and numerous reports have emphasised the need for reduction. Following this there is increased attention to the concept of patient blood management. However, bleeding is relatively common following cardiac surgery and is further enhanced by the continued antiplatelet therapy policy. Another important issue is that cardiopulmonary bypass leads to haemodilution and a potential blood loss. The basic role of blood is oxygen transport to the organs. The determining factors of oxygen delivery are cardiac output, haemoglobin, and saturation. If oxygen delivery/consumption is out of balance, the compensation mechanisms are simple, as a decrease in one factor results in an increase in one or two other factors. Patients with coexisting cardiac diseases may be of particular risk, but studies indicate that patients with coexisting cardiac diseases tolerate moderate anaemia and may even benefit from a restrictive transfusion regimen. Further it has been shown that patients with reduced left ventricular function are able to compensate with increased cardiac output in response to bleeding and haemodilution if normovolaemia is maintained. In conclusion the evidence supports that each institution establishes its own patient blood management strategy to both conserve blood products and maximise outcome.

    Full Text Available Babesiosis is a tick born zoonosis caused by red blood cell parasites of the genus Babesia. It is caused predominantly by B. microti and B. divergens, microti being more common in the US. The parasites are transmitted by Ixodes tick to their host but infection can also spread by blood transfusion and perinatally. Clinical manifestations vary from subclinical infection to fulminating disease depending upon the immune status of the patient. About half of patients, hospitalized with babesiosis, develop complication with fatality rates of 6 to 9% which increase up to 21% among those with immunosuppression. A case of 58-year-old previously healthy man, infected by B. microti, was reported on 2000 who presented with severe disease characterized by severe anemia, DIC, and renal and respiratory failure. First case of overwhelming septic shock without respiratory involvement due to babesiosis in a healthy patient with an intact spleen was published in a case report on 2011. Since our patient here is an immunocompetent healthy male with intact spleen presenting with severe babesiosis requiring exchange transfusion, this presentation of Babesia is rare and warrants further study.

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

    Full Text Available Abstract Background Asthma and sickle cell disease are common conditions that both may result in pulmonary complications. We hypothesized that children with sickle cell disease with concomitant asthma have an increased incidence of vaso-occlusive crises that are complicated by episodes of acute chest syndrome. Methods A 5-year retrospective chart analysis was performed investigating 48 children ages 3–18 years with asthma and sickle cell disease and 48 children with sickle cell disease alone. Children were matched for age, gender, and type of sickle cell defect. Hospital admissions were recorded for acute chest syndrome, cerebral vascular accident, vaso-occlusive pain crises, and blood transfusions (total, exchange and chronic. Mann-Whitney test and Chi square analysis were used to assess differences between the groups. Results Children with sickle cell disease and asthma had significantly more episodes of acute chest syndrome (p = 0.03 and cerebral vascular accidents (p = 0.05 compared to children with sickle cell disease without asthma. As expected, these children received more total blood transfusions (p = 0.01 and chronic transfusions (p = 0.04. Admissions for vasoocclusive pain crises and exchange transfusions were not statistically different between cases and controls. SS disease is more severe than SC disease. Conclusions Children with concomitant asthma and sickle cell disease have increased episodes of acute chest syndrome, cerebral vascular accidents and the need for blood transfusions. Whether aggressive asthma therapy can reduce these complications in this subset of children is unknown and requires further studies.

    Blood transfusion has health-related, economical and safety implications. In order to optimise the transfusion chain, comprehensive research data are needed. The Dutch Transfusion Data warehouse (DTD) project aims to establish a data warehouse where data from donors and transfusion recipients are linked. This paper describes the design of the data warehouse, challenges and illustrative applications. Quantitative data on blood donors (eg, age, blood group, antibodies) and products (type of product, processing, storage time) are obtained from the national blood bank. These are linked to data on the transfusion recipients (eg, transfusions administered, patient diagnosis, surgical procedures, laboratory parameters), which are extracted from hospital electronic health records. Expected scientific contributions are illustrated for 4 applications: determine risk factors, predict blood use, benchmark blood use and optimise process efficiency. For each application, examples of research questions are given and analyses planned. The DTD project aims to build a national, continuously updated transfusion data warehouse. These data have a wide range of applications, on the donor/production side, recipient studies on blood usage and benchmarking and donor-recipient studies, which ultimately can contribute to the efficiency and safety of blood transfusion.

    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)

    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.
