    2009-01-01

    Allogeneic blood transfusion (ABT) is frequently used as the first therapeutic option for the treatment of acute anaemia in patients with inflammatory bowel disease (IBD), especially when it developed due to gastrointestinal or perioperative blood loss, but is not risk-free. Adverse effects of ABT include, but are not limited to, acute hemolytic reaction (wrong blood or wrong patient), febrile non-hemolytic transfusional reaction, bacterial contamination, transfusion-related acute lung injury...

  2. Platelet Vascular Endothelial Growth Factor is a Potential Mediator of Transfusion-Related Acute Lung Injury

    Maloney, James P.; Ambruso, Daniel R.; Norbert F. Voelkel; Silliman, Christopher C

    2014-01-01

    Objective The occurrence of non-hemolytic transfusion reactions is highest with platelet and plasma administration. Some of these reactions are characterized by endothelial leak, especially transfusion related acute lung injury (TRALI). Elevated concentrations of inflammatory mediators secreted by contaminating leukocytes during blood product storage may contribute to such reactions, but platelet-secreted mediators may also contribute. We hypothesized that platelet storage leads to accumulati...

  3. Acute pain transfusion reaction.

    2013-11-01

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

    2009-01-01

    Transfusion-related acute lung injury (TRALI) is a complication following transfusion of blood products and is potentially a life-threatening adverse event of transfusion. The first case of fatal pulmonary edema following transfusion was reported in the 1950s. In recent time, TRALI has developed from an almost unknown transfusion reaction to the most common cause of transfusion related major morbidities and fatalities. A clinical definition of TRALI was established in 2004, based on acute res...

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

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

    Transfusion-related acute lung injury (TRALI) is related to the transfusion of blood components. Typically, it is a clinical syndrome, characterized by the sudden onset of dyspnea, hypoxemia and bilateral non-cardiogenic pulmonary edema. A 83-year-old female patient with a history of AML developed TRALI after receiving 6 units of platelets. TRALI symptoms was started 10 min later the transfusion. AML is a risky group for TRALI. While giving transfusion to the risky groups of TRALI one must be...

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

    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.

    Transfusion-related acute lung injury (TRALI) was introduced in 1983 to describe a clinical syndrome seen within 6 h of a plasma-containing blood products transfusion. TRALI is a rare transfusion complication; however, the FDA has suggested that TRALI is the leading cause of transfusion-related mortality. Understanding the pathogenesis of TRALI will facilitate adopting preventive strategies, such as deferring high plasma volume female product donors. This review outlines the clinical features, pathogenesis, treatment, and prevention of TRALI. PMID:25844126

It is caused by cross reaction between donor antibodies and host leucocytes or between donor leucocytes with host antibodies. TRALI usually presents as an Acute Lung Injury (ALI resulting in pulmonary congestion and edema, often leading to Acute Respiratory Distress Syndrome (ARDS. We report a case of TRALI in a patient who underwent laparotomy for ruptured corpus luteal cyst requiring blood transfusion. She presented with acute pulmonary edema about an hour after commencing a blood transfusion .This was managed conservatively with oxygen, steroids and diuretics. Patient improved rapidly and later discharged without any residual complications.

    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.

    Transfusion-related acute lung injury (TRALI) is the leading cause of transfusion-related mortality. Clinically, TRALI presents as acute lung injury (ALI) (characterized by dyspnea and hypoxemia, with bilateral pulmonary infiltrates) within 6 hours after transfusion of one or more blood products. The pathophysiology of TRALI is incompletely understood, but in part is due to transfusion of certain anti-leukocyte antibodies, or possibly other bioactive substances, into susceptible recipients.

    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.

  8. A suspected case of transfusion-related acute lung injury

    Lulu Sherif

    2011-01-01

    Full Text Available Transfusion-related acute lung injury (TRALI is a rare but serious complication of blood transfusion. We present a suspected case of TRALI in a 39-year-old female patient who underwent total abdominal hysterectomy under uneventful general anesthesia. The patient developed acute desaturation due to noncardiogenic pulmonary edema while receiving compatible blood transfusion on the second postoperative day. As her symptoms were refractory to supportive treatment, she was mechanically ventilated for 3 days and successfully extubated on the fourth day. By exclusion, a clinical diagnosis of TRALI was made. The treatment for TRALI requires discontinuing transfusion and giving respiratory and cardiovascular support. Most cases show clinical improvement in first few hours and resolve completely within 96 h.

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

    2016-05-01

    Transfusion-related acute lung injury (TRALI) may be induced by plasma, platelet concentrates and red blood cell concentrates. The mechanism leading to TRALI is thought to involve two steps. The priming step consists of previous inflammatory pathological conditions or external factors attracting leukocytes to lung vessels and creating conditions favorable for the second step, in which anti-HLA or anti-HNA antibodies or biologically active lipids, usually in transfused blood products, stress leukocytes and inflame lung epithelia. Platelets may be involved in the pathogenesis of TRALI because of their secretory potential and capacity to interact with other immune cells. There is no drug based-prophylaxis, but transfusion strategies are used to mitigate the risk of TRALI. PMID:26855042

    2015-01-01

    Transfusion-related acute lung injury (TRALI) is a life-threatening intervention that develops within 6 hours of transfusion of one or more units of blood, and is an important cause of morbidity and mortality resulting from transfusion. It is necessary to dismiss other causes of acute lung injury (ALI), like sepsis, acute cardiogenic edema, acute respiratory distress syndrome (ARDS) or bacterial infection. There are two mechanisms that lead to the development of this syndrome: immune-mediated and no immune- mediated TRALI. A common theme among the experimental TRALI models is the central importance of neutrophils in mediating the early immune response, and lung vascular injury. Central clinical symptoms are dyspnea, tachypnea, tachycardia, cyanosis and pulmonary secretions, altogether with other hemodynamic alterations, such as hypotension and fever. Complementary to these clinical findings, long-term validated animal models for TRALI should allow the determination of the cellular targets for TRALI-inducing alloantibodies as well as delineation of the underlying pathogenic molecular mechanisms, and key molecular mediators of the pathology. Diagnostic criteria have been established and preventive measures have been implemented. These actions have contributed to the reduction in the overallnumber of fatalities. However, TRALI still remains a clinical problem. Any complication suspected of TRALI should immediately be reported. PMID:26312100

    Transfusion-related acute lung injury (TRALI) is the most common serious side effect of blood transfusion. TRALI could be caused by donor leukocyte antibodies, present primarily in female and transfused donors (Chapters 1 and 2). In The Netherlands this led to the exclusion of female and transfused donors from the donation of plasma for transfusion from 1st October 2006. In this thesis we aimed to quantitatively estimate the expected effect of the implementation of this measure. Chapters 5 th...

    Current notions in immunology hold that not only pathogen-mediated tissue injury but any injury activates the innate immune system. In principle, this evolutionarily highly conserved, rapid first-line defense system responds to pathogen-induced injury with the creation of infectious inflammation, and non-pathogen-induced tissue injury with ‘sterile’ tissue inflammation. In this review, evidence has been collected in support of the notion that the transfusion-related acute lung injury induces ...

    Full Text Available We report the case of a 26-year-old female who underwent emergency caesarean section at a private hospital and was referred to the Government Maternity Hospital (GMH, Tiruapti for bleeding per vaginum 4 hours after delivery. She had received one unit of whole blood transfusion outside. Later, whole blood, platelets (n= 1 unit and fresh frozen plasma (n= 2 units were transfused over a period of 6 hours at GMH, Tirupati. Two hours there after, she complained of sudden breathlessness with cough. On examination, bilateral basal crepitations and wheezing were noted. Fall in oxygen saturation by pulse oximetry, hypotension, tachypnoea and mild fever were also noted. Chest radiograph showed bilateral frontal opacities. Possibility of transfusion-related acute lung injury (TRALI was considered. Supportive treatment included supplemental oxygen through oxygen mask followed by assisted mechanical ventilation and the patient improved. The present case highlights the importance of transfusion related adverse events so as to facilitate prompt recognition and appropriate treatment at the right time.

    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.

    Transfusion-related acute lung injury (TRALI) is a serious adverse reaction of transfusion, and presents as hypoxemia and non-cardiogenic pulmonary edema within 6 hours of transfusion. A 14-year-old primigravida woman at 34 weeks of gestation presented with upper abdominal pain without dyspnea. Because she showed the syndrome of HELLP (hemolysis, elevated liver enzymes, and low platelet count), an emergency cesarean section delivery was performed, and blood was transfused. In the case of such...

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

    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.

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

    Transfusion-related acute lung injury (TRALI) is the major cause of transfusion related morbidity and mortality, world wide. Efforts to reduce or eliminate this serious complication of blood transfusion are hampered by an incomplete understanding of its pathogenesis. Currently, TRALI is thought to be mediated by donor alloantibodies directed against host leukocytes or the result of two distinct clinical events. For both proposed mechanisms the neutrophil (PMN) is the key effector cell. This p...

    Transfusion-related acute lung injury (TRALI) is a serious adverse reaction of transfusion, and presents as hypoxemia and non-cardiogenic pulmonary edema within 6 hours of transfusion. A 14-year-old primigravida woman at 34 weeks of gestation presented with upper abdominal pain without dyspnea. Because she showed the syndrome of HELLP (hemolysis, elevated liver enzymes, and low platelet count), an emergency cesarean section delivery was performed, and blood was transfused. In the case of such patients, clinicians should closely observe the patient's condition at least during the 6 hours while the patient receives blood transfusion, and should suspect TRALI if the patient complains of respiratory symptoms such as dyspnea. Furthermore, echocardiography should be performed to distinguish between the different types of transfusion-related adverse reactions. PMID:26885326

    Blood transfusion is sometimes a necessary procedure during or following coronary artery bypass graft (CABG) surgery. However, transfusion-related acute lung injury (TRALI)/possible TRALI is a rare and fatal complication and characterized by acute hypoxemia and non-cardiogenic pulmonary edema that occurs within 6 hours following a transfusion. Anti-leukocyte antibodies or, possibly, other bioactive substances cause inflammation and capillary endothelial destruction in susceptible recipients' lungs. Prompt diagnosis and mechanical ventilatory support are important. A successful treatment of two male patients following CABG surgery, compatible with TRALI/possible TRALI, is presented here.

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

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

    Transfusion-related acute lung injury (TRALI) is a serious adverse transfusion reaction that is presented as acute hypoxemia and non-cardiogenic pulmonary edema, which develops during or within 6 hr of transfusion. Major pathogenesis of TRALI is known to be related with anti-HLA class I, anti-HLA class II, or anti-HNA in donor's plasma. However, anti-HLA or anti-HNA in recipient against transfused donor's leukocyte antigens also cause TRALI in minor pathogenesis and which comprises about 10% ...

    Transfusion-related acute lung injury (TRALI) is the most common cause of transfusion-related mortality. To explore the pathogenesis of TRALI, we developed an in vivo mouse model based on the passive transfusion of an MHC class I (MHC I) mAb (H2Kd) to mice with the cognate antigen. Transfusion of the MHC I mAb to BALB/c mice produced acute lung injury with increased excess lung water, increased lung vascular and lung epithelial permeability to protein, and decreased alveolar fluid clearance. ...

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.

    2014-10-01

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

    Transfusion-related acute lung injury (TRALI) is a serious clinical syndrome associated with the transfusion of plasma-containing blood components. The classic TRALI syndrome is characterized by the suddenly onset of respiratory failure within 2-6 hrs of the transfusion of a blood product, generally transient, resolves within 48-96 hrs spontaneously, and has a better prognosis. Nonetheless there is an expanded definition of TRALI syndrome up to 72 hrs, which is called delayed TRALI. The poten...

  12. Antibody-mediated transfusion-related acute lung injury; from discovery to prevention.

    Peters, Anna L; Van Stein, Danielle; Vlaar, Alexander P J

    2015-09-01

    Transfusion-related acute lung injury (TRALI), a syndrome of respiratory distress caused by blood transfusion, is the leading cause of transfusion-related mortality. The majority of TRALI cases have been related to passive infusion of human leucocyte antigen (HLA) and human neutrophil antigen (HNA) antibodies in donor blood. In vitro, ex vivo and in vivo animal models have provided insight in TRALI pathogenesis. The various classes of antibodies implicated in TRALI appear to have different pathophysiological mechanisms for the induction of TRALI involving endothelial cells, neutrophils, monocytes and, as very recently has been discovered, lymphocytes. The HLA and HNA-antibodies are found mainly in blood from multiparous women as they have become sensitized during pregnancy. The incidence of TRALI has decreased rapidly following the introduction of a male-only strategy for plasma donation. This review focuses on pre-clinical and clinical studies investigating the pathophysiology of antibody-mediated TRALI. PMID:25921271

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.

    Pathogen reduction technology (PRT) has been developed in an effort to make the blood supply safer, but there is controversy as to whether it may induce structural or functional changes to platelets that could lead to acute lung injury after transfusion. In this study, we used a commercial PRT system to treat human platelets that were then transfused into immunodeficient mice, and the development of acute lung injury was determined. P-selectin expression was higher in the Mirasol PRT-treated ...

  18. Pathogenesis of non-antibody mediated transfusion-related acute lung injury from bench to bedside.

    Peters, Anna L; van Hezel, Maike E; Juffermans, Nicole P; Vlaar, Alexander P J

    2015-01-01

    Transfusion-related acute lung injury (TRALI) is a major cause of transfusion-related mortality. Causative factors are divided in antibody mediated TRALI and non-antibody mediated TRALI. Antibody mediated TRALI is caused by passive transfusion of cognate antibodies and non-antibody mediated TRALI is caused by transfusion of aged cellular blood products. This review focuses on mechanisms in non-antibody mediated TRALI which includes soluble mediators accumulating during storage of red blood cells (RBCs) and platelets (PLTs), as well as changes in morphology and function of aged PLTs and RBCs. These mediators cause TRALI in two-hit animal models and have been implicated in TRALI onset in clinical studies. Pre-clinical studies show a clear relation between TRALI and increased storage time of cellular blood products. Observational clinical studies however report conflicting data. Knowledge of pathophysiological mechanisms of TRALI is necessary to improve storage conditions of blood products, develop prevention strategies and develop a therapy for TRALI. PMID:25277811

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

    Pathogen reduction technology (PRT) has been developed in an effort to make the blood supply safer, but there is controversy as to whether it may induce structural or functional changes to platelets that could lead to acute lung injury after transfusion. In this study, we used a commercial PRT system to treat human platelets that were then transfused into immunodeficient mice, and the development of acute lung injury was determined. P-selectin expression was higher in the Mirasol PRT-treated platelets compared to control platelets on storage day 5, but not storage day 1. Transfusion of control vs. Mirasol PRT-treated platelets (day 5 of storage, 109 platelets per mouse) into NOD/SCID mice did not result in lung injury, however transfusion of storage day 5 platelets treated with thrombin receptor-activating peptide increased both extravascular lung water and lung vascular permeability. Transfusion of day 1 platelets did not produce lung injury in any group, and LPS priming 24 hours before transfusion had no effect on lung injury. In a model of transfusion-related acute lung injury, NOD/SCID mice were susceptible to acute lung injury when challenged with H-2Kd monoclonal antibody vs. isotype control antibody. Using lung intravital microscopy, we did not detect a difference in the dynamic retention of platelets in the lung circulation in control vs. Mirasol PRT-treated groups. In conclusion, Mirasol PRT produced an increase in P-selectin expression that is storage-dependent, but transfusion of human platelets treated with Mirasol PRT into immunodeficient mice did not result in greater platelet retention in the lungs or the development of acute lung injury.

    Transfusion-related acute lung injury (TRALI) is a syndrome of respiratory distress triggered by blood transfusions and is the leading cause of transfusion-related mortality. TRALI has primarily been attributed to passive infusion of HLA and/or human neutrophil antigen antibodies present in transfused blood products, and predisposing factors such as inflammation are known to be important for TRALI initiation. Because the acute-phase protein C-reactive protein (CRP) is highly upregulated during infections and inflammation and can also enhance antibody-mediated responses such as in vitro phagocytosis, respiratory burst, and in vivo thrombocytopenia, we investigated whether CRP affects murine antibody-mediated TRALI induced by the anti-major histocompatibility complex antibody 34-1-2s. We found that BALB/c mice injected with 34-1-2s or CRP alone were resistant to TRALI, however mice injected with 34-1-2s together with CRP had significantly enhanced lung damage and pulmonary edema. Mechanistically, 34-1-2s injection with CRP resulted in a significant synergistic increase in plasma levels of the neutrophil chemoattractant macrophage inflammatory protein-2 (MIP-2) and pulmonary neutrophil accumulation. Importantly, murine MIP-2 is the functional homolog of human interleukin-8, a known risk factor for human TRALI. These results suggest that elevated in vivo CRP levels, like those observed during infections, may significantly predispose recipients to antibody-mediated TRALI reactions and support the notion that modulating CRP levels is an effective therapeutic strategy to reduce TRALI severity.

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

    Full Text Available Acute transfusion reactions have been found to occur during or within 24 hours of transfusion. The aim of this work is to describe the main characteristics of acute reactions reported in a Brazilian transfusion service. A preprinted report form was used to evaluate the age and sex of the transfusion recipients, blood component requested, medical specialty involved and transfusion-related signs and symptoms, transfusionists performed a direct observation during the transfusion and in a period of four hours following transfusion. Data were prospectively collected for 90 days from 30 hospitals and health facilities supplied by the the Service of Hematology and Hemotherapy of São José dos Campos. Acute reactions were recognized as febrile nonhemolytic, allergic, fluid overload, transfusion-related acute lung injury (TRALI, anaphylatic and metabolic reactions. In a total of 8,378 transfusions, 46 acute reactions were recorded (5.5 per 1000 units transfused, 28 febrile nonhemolytic, 12 allergic, 5 anaphylatic and 1 fluid overload. TRALI and metabolic reactions were not detected. The majority (27 was associated with RBCs followed by PLTs 11, FFP 6 and partial units 2. The median age of the recipients was 43 years (3 months to 83 years, 23 males and 23 females. Overall, 12 (26.1% events were recorded in oncology, 12 (26.1% in medicine and 7 in intensive care unit departments. This study provides baseline acute transfusion reaction information for a specific period of time in a Brazilian transfusion service.As reações transfusionais agudas ocorrem durante ou em um período de até 24 horas após a transfusão de hemocomponentes.

    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.

  7. Transfusion Related Acute Lung Injury: A severe case triggered with anti-HLA class II antibodies in the recipient

    2012-04-01

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

    2008-12-01

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

    2008-07-01

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

    2011-12-01

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

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

    2016-09-01

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

    Full Text Available El término TRALI (transfusion related acute lung injury "lesión pulmonar aguda producida por transfusión" fue acuñado en 1985. Es un síndrome clínico relativamente raro, que puede constituir una amenza para la vida y que se caracteriza por insuficiencia respiratoria aguda y edema pulmonar no cardiogénico durante o después de una transfusión de productos hemáticos. Aunque su verdadera incidencia es desconocida se le ha atribuido un caso por cada 5.000 transfusiones de cualquier producto hemático y ha sido la causa más frecuente de muerte relacionada con la transfusión durante 3 años en Estados Unidos. Se han propuesto 2 etiologías. La primera es un episodio mediado por anticuerpos debido a la transfusión de anticuerpos contra el antígeno leucocitario o anticuerpos antigranulocito a pacientes cuyos leucocitos presentan antígenos afines. La segunda es un modelo en el que se precisan 2 eventos: el primero está relacionado con el cuadro clínico del receptor (sepsis, trauma, etc. que produce activación endotelial y secuestro de neutrófilos, y el segundo es la transfusión de sustancias con capacidad de modificar la respuesta biológica que activa los leucocitos adheridos que produce daño endotelial y aumento de permeabilidad capilar. El tratamiento es de soporte en función de la gravedad del cuadro clínico, y la prevención se centra en 3 estrategias: selección de donantes, actuación sobre el almacenamiento de los productos hemáticos y evitar las transfusiones innecesarias.The term Transfusion-Related Acute Lung Injury (TRALI was coined in 1985.

    Transfusion-related acute lung injury (TRALI) is known to be the leading cause of transfusion-related mortality. A nearly fatal case of postoperative TRALI, successfully managed with extracorporeal membrane oxygenation (ECMO), is reported. The patient was a 70-year-old woman for whom laparoscopic nephrectomy was planned. She received several units of packed red blood cells and fresh-frozen plasma (FFP) intraoperatively due to massive bleeding. At the end of the operation, her PaO2/FIO2 ratio was 504, and she was extubated. Shortly after extubation, she developed severe hypoxemia. A chest X-ray showed bilateral infiltrates without cardiac enlargement. After entering the ICU, her respiratory condition deteriorated rapidly despite treatment with noninvasive positive pressure ventilation followed by re-intubation 8 hours after the operation. Even with very high positive pressure ventilation above 35 mmHg, her oxygenation decreased to PaO2 39.9 mmHg (FIO2 1.0). As a lifesaving measure, venovenous ECMO was started 15 hours after the operation. The pulmonary infiltration improved significantly over the next 5 days. Anti-HLA antibodies were detected in the FFP donor serum, that was transfused at the time of extubation. Now that TRALI is thought to be reversible, ECMO might be useful for even what was previously fatal hypoxemia. PMID:26689071

    2010-01-01

    El término TRALI (transfusion related acute lung injury "lesión pulmonar aguda producida por transfusión") fue acuñado en 1985. Es un síndrome clínico relativamente raro, que puede constituir una amenza para la vida y que se caracteriza por insuficiencia respiratoria aguda y edema pulmonar no cardiogénico durante o después de una transfusión de productos hemáticos. Aunque su verdadera incidencia es desconocida se le ha atribuido un caso por cada 5.000 transfusiones de cualquier producto hemát...

    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 o...

  4. 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.

    As screening for transfusion-associated infections has improved, non-infectious complications of transfusion now cause the majority of morbidity and mortality associated with transfusion in the United States. For example, transfusion-related acute lung injury, transfusion-associated circulatory overload, and hemolytic transfusion-reactions are the first, second, and third leading causes of death from transfusion respectively. These complications and others are reviewed here and several contro...

  10. Transfusion practices in trauma

    V Trichur Ramakrishnan

    2014-01-01

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

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

  12. Red cell transfusion and the immune system.

    Hart, S; Cserti-Gazdewich, C M; McCluskey, S A

    2015-01-01

    Understanding the complex immunological consequences of red cell transfusion is essential if we are to use this valuable resource wisely and safely. The decision to transfuse red cells should be made after serious considerations of the associated risks and benefits. Immunological risks of transfusion include major incompatibility reactions and transfusion-related acute lung injury, while other immunological insults such as transfusion-related immunomodulation are relatively underappreciated. Red cell transfusions should be acknowledged as immunological exposures, with consequences weighed against expected benefits. This article reviews immunological consequences and the emerging evidence that may inform risk-benefit considerations in clinical practice. PMID:25440393

    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. PMID:21325598

    Handa, Makoto

    2015-10-01

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

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

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

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

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

    Matignon, M; Bonnefoy, F; Lang, P; Grimbert, P

    2011-04-01

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

Aims : To evaluate the efficacy of clofibrate in reducing total serum bilirubin levels in late pre-term neonates with non-hemolytic jaundice. Design and Setting : Double-blind, placebo-controlled, randomized trial; tertiary level neonatal unit. Materials and Methods : A randomized controlled study was carried out in the neonatal ward of Children′s Hospital, Tabriz, Iran, over a 1-year period. Sixty-eight healthy late pre-term infants readmitted with non-hemolytic hyperbilirubinemia were randomized to receive phototherapy and clofibrate (n= 35 or phototherapy and placebo (n= 33. Statistical Analysis Used : Chi-square test and independent sample ′t′ test. Results : There were no significant differences in the weight, gender, modes of delivery and age of neonates between the two groups. Similarly the mean total serum bilirubin (TSB level at the time of admission was not significantly different between the two groups [mean± SD: 19.72 ± 1.79 (95% confidence interval: 19.12-20.54 mg/dL vs. 20.05 ± 2.82 (95% confidence interval, 19.54-22.04 mg/dL, P= 0.57].

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

    2015-11-01

    Transfusion-related acute lung injury (TRALI) is the leading cause of transfusion-associated morbidity and mortality. Activated platelets have important roles in TRALI and CD62P was identified to be an important indicator of platelet activation. However, the precise roles of CD62P in TRALI have remained elusive. The present study assessed CD62P accumulation during storage of apheresis platelet concentrates (A‑Plts) and established a mouse model of TRALI to further investigate the roles of CD62P in TRALI. The results showed that the CD62P concentration in A‑Plts was increased with the storage time. Mice were treated with monoclonal major histocompatibility complex (MHC)‑1 antibody to induce TRALI. The murine model of TRALI was successfully established as evidenced by pulmonary oedema, accompanied by decreased clearance of bronchoalveolar lavage fluid (BALF), increased pulmonary and systemic inflammation, elevated lung myeloperoxidase (MPO) activity as well as increased pulmonary and systemic coagulation in the TRALI group compared with those in the control group. To further determine the role of CD62P in TRALI, mice were treated with anti‑CD62P antibody to knockdown CD62P in vivo. It was found that pulmonary oedema, BALF clearance, pulmonary and systemic inflammation, MPO activity as well as pulmonary and systemic coagulation were decreased in the TRALI + anti‑CD62P antibody group compared with those in the TRALI + isotype antibody group. The present study supported the notion that CD62P is involved in mediating TRALI and may provide an important molecular basis for enhancing the clinical safety and effectiveness of platelet transfusion.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: Após sua descrição há mais de 20 anos, a TRALI - transfusion related acute lung injury - tornou-se, nos Estados Unidos e na Inglaterra, a principal causa de morbidade e mortalidade relacionada com transfusão sanguínea. Por não existirem dados confiáveis com relação à sua epidemiologia no Brasil, seu diagnóstico é difícil, pois seu quadro clínico é variado e não há dados laboratoriais específicos. Sendo assim, os relatos de casos tornam-se importantes. É o primeiro relato dessa reação transfusional, neste situação cirúrgica, indexado na base de dados LILACS. RELATO DO CASO: Paciente do sexo feminino, 36 anos, submetida à mastectomia com reconstrução microcirúrgica de mama sob anestesia geral. Logo após o término da transfusão de concentrado de hemácias, na sala de recuperação pós-anestésica, evoluiu com insuficiência respiratória, não necessitando reintubação traqueal. Foi realizado tratamento de suporte em unidade de terapia intensiva após serem descartadas outras hipóteses diagnósticas. Evoluiu bem, recebendo alta hospitalar no quarto dia de pós-operatório, sem seqüelas. CONCLUSÕES: Ressalta-se a importância da realização criteriosa de transfusão sanguínea, pois, apesar da transmissão de doenças ser rara, a ocorrência de TRALI é muito freqüente, contudo subestimada pela diversidade de hipóteses diagnósticas. Por isso é salutar o conhecimento e divulgação dessa doença, sobretudo em nosso meio.JUSTIFICATIVAS Y OBJETIVOS: Después de su descripción hace más de 20 años, la TRALI - Transfusion Related Acute Lung Injury se convirtió, en los Estados Unidos de América y en Inglaterra, en la principal causa de morbidez y mortalidad relacionada con la transfusión sanguínea.

  10. Current understanding of allergic transfusion reactions: incidence, pathogenesis, laboratory tests, prevention and treatment

    Hirayama, Fumiya

    2012-01-01

    Non-haemolytic transfusion reactions are the most common type of transfusion reaction and include transfusion-related acute lung injury, transfusion-associated circulatory overload, allergic reactions, febrile reactions, post-transfusion purpura and graft-versus- host disease. Although life-threatening anaphylaxis occurs rarely, allergic reactions occur most frequently. If possible, even mild transfusion reactions should be avoided because they add to patients' existing suffering. During the ...

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

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

  12. TRALI - A Less Commonly Known Complication of Transfusion

    Pradeep Bhatia

    2008-01-01

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

    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).

    TR Nijamin

    Full Text Available La enfermedad injerto vs hospedero (EICH es un proceso inmunológico, desencadenado por linfocitos T de un donante inmunocompetente, que reaccionan contra los tejidos de un receptor inmunocomprometido. Esto origina daño multiorgánico severo en el agente receptor. Las manifestaciones cutáneas son un signo clínico relevante en períodos tempranos. La EICH postranfusional (EICH-PT es una entidad poco frecuente y con alta tasa de mortalidad, que se observa en pacientes luego de transfusiones con hemoderivados no irradiados. Los corticoides son el pilar fundamental del tratamiento, una vez instalado el cuadro. La prevención con leucorreducción e irradiación de los componentes sanguíneos, constituye el sustento primordial para evitar su desarrollo. Presentamos un paciente de 5 años de edad, con un diagnóstico de leucemia linfoblástica aguda de alto riesgo, de múltiples transfusiones de glóbulos rojos sin tratamiento radiante previo, a quien se le realiza el diagnóstico dermatológico e histopatológico de EICH aguda postransfusional.Graft vs host disease (GVHD is a process triggered by immune T cells, that react immunocompetent donor tissue against a recipient immunocompromised. This causes severe multiorgan damage in the receiving agent. Cutaneous manifestations are an important clinical sign in early periods. Postranfusional GVHD (GVHD-PT is a rare entity with high mortality rate, observed in patients after transfusion with blood products not previously irradiated. Corticosteroids are the mainstay of treatment after installation of the box, however prevention with leukoreduction and irradiation of blood components remains the mainstay to prevent its development. We present a patient 5 years of age, diagnosed with acute lymphoblastic leukemia at high risk with a history of multiple transfusions of red blood cells without prior radiation treatment, who is performed dermatological and histopathological diagnosis posttransfusion acute GVHD.

  18. Management of Patients with Sickle Cell Disease Using Transfusion Therapy: Guidelines and Complications.

    Chou, Stella T; Fasano, Ross M

    2016-06-01

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

    2013-01-01

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

  4. Post-transfusion red cell alloimmunisation in patients with acute disorders and medical emergencies Aloimunização após transfusão de concentrado de hemácias em pacientes atendidos em um serviço de emergência

    Francisco W. R. Santos

    2007-12-01

    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.

    2011-01-01

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

    2008-03-01

    Full Text Available La injuria pulmonar aguda asociada a transfusión (TRALI es un evento poco frecuente, especialmente raro en la práctica obstétrica. Sin embargo, hoy en día es la principal causa de muerte asociada a dicho procedimiento. Su mortalidad es alrededor del 6%. Desde el 2004 se definieron los criterios diagnósticos de TRALI que deben ser tenidos en cuenta para su identificación y tratamientos tempranos. Se presenta el caso de una gestante con 30 semanas de embarazo, hospitalizada con diagnóstico de infección urinaria, a quien se le transfundió una unidad de glóbulos rojos después de evaluar un resultado de hemoglobina de 6,7 g/dl, una hora después presentó síndrome de dificultad respiratoria aguda severa que requirió ventilación mecánica por cuatro días. El resultado materno y perinatal fue óptimo con resolución completa del evento respiratorio. Se considera relevante reportar el caso para motivar la notificación de esta complicación, pues se desconoce la influencia del embarazo sobre ella. Además, se le debe informar al banco de sangre para fortalecer el sistema de hemovigilancia.Transfusion-related acute lung injury (TRALI is an uncommon complication, especially in obstetrics. The mortality rate for this event is around 6% and has now become the leading cause of transfusion-related death. TRALI diagnosis criteria have been well established since 2004 and they must be considered for its early identification and treatment. We report a case of a 30-week pregnant woman who suffered a urinary tract infection. She received a blood transfusion with one unit of red blood cells due to having 6.7 gr/dl having 6.7 gr/dl haemoglobin. One hour later she developed an acute respiratory distress syndrome and required four days’ mechanical ventilation. Maternal and neonatal outcome were optimal, leading to complete resolution of respiratory symptoms. This case should be shared to motivate reporting this kind of complication because the

    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 lo...

  10. Ensemble learning approaches to predicting complications of blood transfusion.

    Murphree, Dennis; Ngufor, Che; Upadhyaya, Sudhindra; Madde, Nagesh; Clifford, Leanne; Kor, Daryl J; Pathak, Jyotishman

    2015-08-01

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

  11. Red Blood Cell Transfusion Strategies in Adult and Pediatric Patients with Malignancy.

    Roubinian, Nareg; Carson, Jeffrey L

    2016-06-01

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

  12. A review of the application of autologous blood transfusion.

    Zhou, J

    2016-01-01

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

  16. Microbes and blood transfusion

    Narayan S

    2001-01-01

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

  17. Metabolomics in transfusion medicine.

    Nemkov, Travis; Hansen, Kirk C; Dumont, Larry J; D'Alessandro, Angelo

    2016-04-01

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

  18. Problems of multiple transfusions.

    GARDNER, F H

    1958-02-01

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

  19. Transfusion of granulocyte rich buffy coats to neutropenic patients.

    Reiss, R F; Pindyck, J; Waldman, A A; Raju, M; Kulpa, J

    1982-01-01

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

  20. [Autologous transfusion in obstetrics and fetal safety].

    Rech, F; Patella, A; Cecchi, A; Ippolito, M; Indraccolo, S R

    1994-06-01

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

  4. Thrombelastography Guides Transfusion Strategy

    Bay Nielsen, Henning

    2009-01-01

    During surgery for an abdominal aortic aneurysm, coagulation may be impaired and the use of thrombelastography (TEG) is described in six patients with a perioperative blood loss of 3L. During surgery blood products were infused but not platelets. When the patients were admitted to the intensive care unit, the TEG report demonstrated a lowered MA value indicating impaired function of platelets. The use of TEG may guide transfusion strategy.

  5. Pulmonary insults due to transfusions, radiation, and hyperoxia

    Pulmonary insults caused by transfusion, radiation, and hyperoxia share many clinical features with insults caused by serious pulmonary infections. The major objective in evaluating these patients is to establish the diagnosis with as much certainty as possible. Unfortunately, there are no clinical aspects or laboratory tests that are pathognomonic for these diseases; therefore, it is often necessary to rely on a knowledge of those features which help to distinguish these disorders from infectious etiologies. For example, patients suffering from transfusion-related acute lung injury (TRALI) experience onset of insult within 6 hours of a transfusion and have the presence of leukoagglutinins in their serum. Patients with radiation injuries frequently have roentgenographic infiltrates that conform to the ports of radiation. Despite extensive animal and human studies, factors distinguishing hyperoxic injury from infectious disorders remain poorly defined. These clinical features and others are reviewed to identify the essential components in the diagnosis of TRALI, acute radiation pneumonitis, and hyperoxic pneumonitis. 84 references

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

    2014-06-01

    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

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

  11. Exchange transfusion of a patient with fulminant Lassa fever.

    Cummins, D.; Bennett, D.; Machin, S. J.

    1991-01-01

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

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

  17. Blood transfusion practices in cardiac anaesthesia

    Hanumantha Rao Mangu

    2014-01-01

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

  18. Hemoglobin optimization and transfusion strategies in patients undergoing cardiac surgery

    Mahdi; Najafi; David; Faraoni

    2015-01-01

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

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

    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.

    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 Glu151Asp 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.

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

    Ted Wun

    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.

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

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

  15. Transfusion-transmitted parasitic infections.

    Singh, Gagandeep; Sehgal, Rakesh

    2010-07-01

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

    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-...

  18. Blood transfusion economics in Greece.

    Kyriopoulos, J E; Michail-Merianou, V; Gitona, M

    1995-01-01

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

    Full Text Available Donor specific transfusion (DST is proclaimed to improve graft survival in living related kidney transplantation (LRTx. The aim of the present study was to estimate the influence of DST on LRTx graft function, acute rejection rate (AR and survival in the early and late post transplant period. Fifty-five LRTx patients (grafted in the same year, and matched for recipients' and donor's age, sex were included into the study. Ninety pts received DST: 4 patients were excluded from further evaluation (3 developed positive cross match reaction and one patients received cadaver graft and 15 patients subsequently underwent LRTx from their respective blood donors (group 1. Their outcome was compared with 15 patients who had never been transfused before (group 2 and 25 random transfused patients (group 3. Besides similar patients' and donors' sex and age, kidney transplantations were performed in the same period. Graft functions were followed-up 6-60 months after LRTx. DST protocol consists of 3x150 ml potentially related donor's fresh whole blood at 2-week intervals (DST1, DST2, DST3 with 3 days azathioprine administration (2 mg/kg bw, one day before to one day after DST administration. Donor specific citotoxic antibodies were determined before DST1, at the day of DST2, DST3 and 14 and 28 days after DST3. All patients were grafted at least one month after the DST3. Immunosuppressive protocol consisted of three drugs. There is no difference in HLA mismatches, MLC answer, and pretransplant panel reactive antibodies level between groups. One patient from group 2 lost their graft in the first postTx month (acute tubular necrosis. A better graft function was preserved in patients from groups 1 and 3 than group 2 in the observed periods. Number of patients with acute rejection was unsignificantly different: 5/15 from group 1,12/25 from group 3 but 8/10 patients from group 2. However, the acute rejection rate was lower in patients from group 1. One and five

  3. Transfusion-Transmitted Babesia microti.

    Fang, Deanna C; McCullough, Jeffrey

    2016-07-01

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

  5. Patch: platelet transfusion in cerebral haemorrhage: study protocol for a multicentre, randomised, controlled trial

    Dijkgraaf Marcel G

    2010-03-01

    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.

    2015-10-01

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

  7. Recurrent abortions and lymphocyte transfusions.

    Bjercke, S

    1994-05-01

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

  8. [Blood transfusion: the challenges for tomorrow?].

    Folléa, Gilles; Garraud, Olivier; Tiberghien, Pierre

    2015-02-01

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

Unfortunately, despite the fact that transfusions are associated with a number of infectious and noninfectious risks, and in spite of the fact that there are ethical, accreditation, and regulatory requirements to provide information regarding transfusion risks, benefits, and alternatives to patients, transfusion consent remains inconsistently obtained. This can partly be attributed to the fact that clinicians may take on a paternalistic approach to transfusion decisions as well as to the fact that many clinicians have knowledge gaps in transfusion medicine that prevent them from obtaining transfusion consent adequately. As a result, unlike the case with other medical and surgical therapies, most patients are not included in the making of informed decisions regarding the need for transfusion versus alternative therapies, leading to many situations in which the transfusions provide little benefit to them. Recently however, a number of organizations, such as the American Association of Blood Banks and The Joint Commission in the US, have promoted multidisciplinary, evidence-based treatment strategies that aim to minimize the need for blood transfusion, the so-called patient blood management (PBM protocols. PBM strategies are expected to improve blood utilization through optimization of patients who may need

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.

  13. Adverse blood transfusion outcomes: establishing causation.

    2011-04-01

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

    2015-01-01

    Despite the advances in platelet component preparation and transfusion support over the years, platelet products remain a limited resource due to their short (5 day) shelf life, and therefore their optimal use in the non-bleeding thrombocytopenic patient continue to draw much attention. There have been a number of national and international guidelines for platelet transfusion therapy in patients with hematologic diseases, some within the last 1-2 years that have incorporated key randomized controlled trials (RCTs) which address issues, such as the optimal platelet dose, the most appropriate threshold for prophylactic platelet transfusions, and whether prophylactic platelet transfusions are superior to therapeutic-only platelet transfusion practices for the prevention life-threatening bleeding in patients with hypoproliferative thrombocytopenia. This review highlights key RCTs and recent systematic reviews focused on optimal platelet transfusion therapy in adult and pediatric patients with hypoproliferative thrombocytopenia secondary to chemotherapy or hematopoietic stem cell transplant (HSCT), discuss how recent innovations in platelet component processing may affect transfusion efficiency, and introduce renewed concepts on adjuvant therapies to prevent bleeding in the hypoproliferative thrombocytopenic patient.

  16. Nurses' perceptions of transfusion training: an evaluation.

    Stout, Lynn

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

  17. Transfusion regimens in thalassemia intermedia

    Z. Karakas

    2011-12-01

    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

    P. Van der Linden

    2007-07-01

    Full Text Available The adequacy of a hemoglobin concentration in a given clinical situation depends on whether a sufficient amount of oxygen is carried to the tissues to meet metabolic requirements. Therefore, the decision to transfuse a given patient cannot be based only on the hemoglobin level. Rather, rigid adherence to an arbitrarily predefined transfusion threshold will result in the over-transfusion of some patients, but also in the under-transfusion of others. A better knowledge of the physiologic responses developed during acute isovolemic anemia and the clinical factors that can limit the ability of the organism to maintain adequate tissue oxygenation in these situations, will allow the clinician to better define the transfusion trigger for each patient. This paper reviews the physiological and clinical factors of acute isovolemic anemia and presents the therapeutic options available.

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

    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 ...

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

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

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

  6. Blood transfusion practices in obstetric anaesthesia

    Ashok Jadon

    2014-01-01

    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.

  7. Blood transfusion practices in liver transplantation

    M N Chidananda Swamy

    2014-01-01

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

  8. [Correct preparation of a transfusion: Part 1].

    Strobel, E; Henschler, R

    2014-09-01

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

    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).

  13. [Single-donor protocol: Transfusion practices and multiple transfusion risk factors in neonatal intensive care unit].

    Dollat, C; Pierron, C; Keslick, A; Billoir, E; François, A; Jarreau, P-H

    2016-09-01

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

  14. Red Kidney: Kidney Transplant From a Deceased Donor Who Received Massive Blood Transfusion During Cardiopulmonary Bypass.

    Bell, Richard; Hanif, Faisal; Prasad, Padmini; Ahmad, Niaz

    2016-06-01

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

  15. A case of transfusion independence in a patient with myelodysplastic syndrome using deferasirox, sustained for two years after stopping therapy

    2015-01-01

    Patients with myelodysplastic syndrome (mds) experience clinical complications related to progressive marrow failure and have an increased risk of developing acute myeloid leukemia. Frequent red blood cell transfusion can lead to clinical iron overload and is associated with decreased survival in mds patients. Iron chelation therapy reduces markers of iron overload and prevents end-organ damage.

  16. Facility-based constraints to exchange transfusions for neonatal hyperbilirubinemia in resource-limited settings

    Mabogunje, Cecilia A.; Olaifa, Sarah M; Olusanya, Bolajoko O

    2016-01-01

    Several clinical guidelines for the management of infants with severe neonatal hyperbilirubinemia recommend immediate exchange transfusion (ET) when the risk or presence of acute bilirubin encephalopathy is established in order to prevent chronic bilirubin encephalopathy or kernicterus. However, the literature is sparse concerning the interval between the time the decision for ET is made and the actual initiation of ET, especially in low- and middle-income countries (LMICs) with significant r...

    Anemia and resultant red blood cell transfusion may be associated with adverse long-term clinical outcomes. To investigate the mechanism(s) responsible, we profiled inflammatory biomarkers and circulating levels of the bioactive lysophospholipid mediator sphingosine-1-phosphate (S1P) in control and anemic mice with or without LPS-induced systemic inflammation. Acute anemia or lipopolysaccharide (LPS) challenge alone triggered an increase of circulating levels of the inflammatory markers IL-6 ...

    ABSTRACT A man was accidentally immersed in hot acidic trivalent chromium sulphate solution but none was swallowed. The clinical course was dominated by burns, intravascular haemolysis, and acute renal failure. Blood concentrations of chromium were measured during treatment and tissue concentrations were measured at death. Exchange transfusion reduced blood chromium concentrations by two-thirds. The total quantities of chromium absorbed and removed by various routes were calculated. In-vitro ...

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

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

    Full Text Available 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.

    2003-10-01

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

  3. Where are the systematic reviews in transfusion medicine? A study of the transfusion evidence base.

    Dorée, Carolyn; Stanworth, Simon; Brunskill, Susan J; Hopewell, Sally; Hyde, Chris J; Murphy, Mike F

    2010-10-01

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

    2016-03-01

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

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

    2009-01-01

    Full Text Available Background: Thalassemia is a common hemoglobin disorder in Iran and one of the major public health problems. Although blood transfusions are lifesavers for thalassemia patients, they may be associated with some complications especially erythrocyte alloimmunization. The purpose of this study was to investigate the prevalence of red blood cell alloantibodies and to determine types of these antibodies among multiple-transfused thalassemic patients. Materials and Methods: A total of 313 thalassemia patients in the northeast of Iran, who received regular blood transfusion, were included in this study. Screening of antibodies was performed on fresh serum of all patients and then antibodies were identified in patients′ serum that had positive antibody screening test using a panel of recognized blood group antigens. Results: We identified 12 alloantibodies in 9 patients (2.87% that all were against Rhesus (Rh blood group antigens (D, C, E. Three patients developed 2 antibodies, and others had one antibody. The most common alloantibodies were Anti-D (88.88% and followed by Anti-C and Anti-E. Higher frequency of alloimmunization was observed in female, Rh negative and splenectomized patients. Conclusion: This study showed that evaluation of the packed cells for Rh (C, E from the start of transfusion can be helpful in decreasing the rate of alloantibody synthesis.

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

  17. Transfusion practice in orthotopic liver transplantation

    Devi Allanki

    2009-01-01

    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.

    2011-04-01

    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.

  19. Anemia and Blood Transfusions in Critically Ill Patients

    2012-01-01

    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.

  20. 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. 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.

  2. Bar code technology improves positive patient identification and transfusion safety.

    Sandler, S G; Langeberg, A; Dohnalek, L

    2005-01-01

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

    Patients undergoing pancreaticoduodenectomy (PD) often require transfusion. However, transfusion-related complications and decreased blood donation in Korea encourage the development of new treatment strategies for PD patients. Although transfusion-free (TF) operation is thought to be beneficial, results supporting its beneficial effects are lacking. The aim of our study was to demonstrate the impact on PD patients of a TF program. From December 2003 to April 2013, 80 consecutive patients with periampullary lesions underwent PD performed. These patients were divided into two groups as follows: 39 PD patients in the "before TF program" (Group 1) and 41 PD patients in the "after TF program" (Group 2). Among patients in Group 2, patients who agreed with the TF program were enrolled and proceed with the TF program prospectively. Participants in the TF program had perioperative blood augmentation and intraoperative acute normovolemic hemodilution. The perioperative data were compared with the two groups. The mean preoperative hemoglobin, operative times, and operative blood loss showed no significance between two groups. The mean postoperative hemoglobin was lower in Group 2 (11.7 g/dL vs 10.9 g/dL, P = 0.038). The mean amount of blood transfusion was significantly lower in Group 2. (950.8 mL vs 124.9 mL, P = 0.009). The TF program considerably decreases the amount of perioperative blood transfusion. The overall perioperative course and complication rate in the TF group were not inferior to those in the non-TF group. The TF program appears safe and should be considered in PD patients.

  4. Perioperative neonatal and paediatric blood transfusion

    Avnish Bharadwaj

    2014-01-01

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

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

    2013-01-01

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

  13. Blood transfusion safety: a new philosophy.

    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.

    1989-01-01

    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...... receiving transfusion (age, sex, B-hemoglobin, S-albumin, type and duration of surgery, etc.), which confirmed thata more pronounced reduction in postoperative skin test response was found in transfused patients (-55% vs -31%, p less than 0.0001). Seventeen of the 33 patients treated with perioperative...... 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...

  1. Alloimmunization screening after transfusion of red blood cells in a prospective study Pesquisa de aloimunização após transfusão de concentrados de hemácias em um estudo prospectivo

    Vitor Mendonça Alves

    2012-01-01

    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.

  3. Transfusion of fresh frozen plasma in non-bleeding ICU patients -TOPIC TRIAL: study protocol for a randomized controlled trial

    Müller Marcella CA

    2011-12-01

    Full Text Available Abstract Background Fresh frozen plasma (FFP is an effective therapy to correct for a deficiency of multiple coagulation factors during bleeding. In past years, use of FFP has increased, in particular in patients on the Intensive Care Unit (ICU, and has expanded to include prophylactic use in patients with a coagulopathy prior to undergoing an invasive procedure. Retrospective studies suggest that prophylactic use of FFP does not prevent bleeding, but carries the risk of transfusion-related morbidity. However, up to 50% of FFP is administered to non-bleeding ICU patients. With the aim to investigate whether prophylactic FFP transfusions to critically ill patients can be safely omitted, a multi-center randomized clinical trial is conducted in ICU patients with a coagulopathy undergoing an invasive procedure. Methods A non-inferiority, prospective, multicenter randomized open-label, blinded end point evaluation (PROBE trial. In the intervention group, a prophylactic transfusion of FFP prior to an invasive procedure is omitted compared to transfusion of a fixed dose of 12 ml/kg in the control group. Primary outcome measure is relevant bleeding. Secondary outcome measures are minor bleeding, correction of International Normalized Ratio, onset of acute lung injury, length of ventilation days and length of Intensive Care Unit stay. Discussion The Transfusion of Fresh Frozen Plasma in non-bleeding ICU patients (TOPIC trial is the first multi-center randomized controlled trial powered to investigate whether it is safe to withhold FFP transfusion to coagulopathic critically ill patients undergoing an invasive procedure.

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

    Schneider, William H

    2013-01-01

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

  8. Transfusion interventions in critical bleeding requiring massive transfusion: a systematic review.

    2015-04-01

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

  9. Contemporary issues in transfusion medicine informatics

    Gaurav Sharma

    2011-01-01

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

  10. Total quality management in blood transfusion.

    Smit-Sibinga, C T

    2000-01-01

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

  1. REDUCCIÓN DE TRANSFUSIONES ALOGÉNICAS EN CIRUGÍA CARDÍACA EMPLEANDO UN PROGRAMA DE AHORRO DE SANGRE / The reduction of allogeneic blood transfusions in cardiac surgery using a blood saving program

    Altinay Padrón Bulit

    2009-09-01

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

  2. Autologous blood transfusion in patients undergoing hip replacement surgery

    Tešić Ivana

    2014-01-01

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

    2016-01-01

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

    2015-09-01

    Full Text Available BACKGROUND: Alloimmunization is one of the major concern in the management of patients who required repeated blood transfusion as a lifesaving treatment . The knowledge of incidence of such alloantibodies is essential for selecting appropriate red blood cells for transfusion . AIMS: This study was carried out to get the frequency and type of unexpected red cell antibodies in the multi - transfused patient at a tertiary level government hospital in South Gujarat . MATERIALS AND METHODS: This prospective study was carried out in 200 patients who required multiple blood transfusions . The antibody screening was done with 3 & 11 commercial cell screening & identification panel by column agglutination technique (Matrix Gel System & Matrix Erygen AS - ID, Tulip Diagnostics, India at saline & anti - human globulin phase . RESULTS: The overall prevalence of alloimmunization was 7 . 0% . The majority of these had a single alloantibody (11 cases, 84 . 62% whereas the remaining 2 cases (15 . 38% had multiple antibodies . The anti - c and anti - D antibodies comprised the most common alloantibody (27 % each both followed by, anti - N (20%, anti - C (13%, anti - e & anti - M (7% antibodies . Gender & number of blood units were found to be risk factors of alloimmunization in transfused patients . In our study we found females (79% are more prone to alloimmunization . Those who were transfused more than 2 units have higher frequency of alloimmunization . The highest incidence of alloimmunization was observed in obstetrics and sickle cell patients . CONCLUSIONS: The majority of alloantibodies detected in the current study were clinically significant and of mainly belonging to Rh blood group system . Thus pre - transfusion antibody screening on patients’ samples prior to cross - match needs to be initiated in India and we can at - least provide corresponding Rh antigen negative blood to ensure safe transfusion practice

  17. Improved survival of newborns receiving leukocyte transfusions for sepsis

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

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

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

    2010-01-01

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

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

    Orthotopic liver transplantation (OLT) is the treatment of choice for patients with acute or chronic end-stage liver disease, irresectable primary liver tumor, and metabolic disorders. Historically, OLT has been associated with considerable blood loss and the need for transfusions. However, over the years there has been reduction is need for blood products. The aim of this article was to compare two distinct eras for perioperative blood transfusion rate among patients undergoing OLT; Era I, 200 transplantations in 188 patients, and Era II, 355 transplantations in 339 patients. The donor mean age was 33.70 (Era I) versus 35.34 (Era II). Cause of death in both eras was traumatic brain injury followed by cerebral vascular accident. Organ recipient data showed a mean age of 48.87 (Era I) versus 46.49 (Era II). During Era I patients with Child B (56.8%) prevailed, followed by Child C (35.4%) and Child A (7.8%). In Era II also patients with Child B (53.1%) prevailed, followed by Child C (39.6%) and Child A (7.3%). The prevalence of hepatocellular carcinoma (HCC) during Era I was 9% (18) and in Era II 20% (71). The use of blood products in the perioperative period: was as follows packed red blood cells 1.76 (Era I) versus 0.57 (Era II) units; fresh frozen plasma 1.89 (Era I) versus 0.49 (Era II) units; platelets 2.16 (Era I) versus 0.28 (Era II) units; and cryoprecipitate 0.08 (Era I) versus 0.03 (Era II) units. OLT using the piggyback technique was performed with a transfusion rate below <30%, and it reduced blood loss and prevented severe hemodynamic instability. PMID:24182806

  4. Effects of blood transfusion on exercise capacity in thalassemia major patients.

    Daniela Benedetto

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

    2012-04-01

    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.

    Khatami S.F

    2007-09-01

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

  7. Exchange transfusion for severe malaria: A comparison of red cell exchange with whole blood exchange

    Udani S

    2003-01-01

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

    One of the largest therapeutic problem during the continuous treatment of the patients with Hemophilia A and B, are viral infections as Hepatitis B and C, and HIV, and the other infective diseases, which can be transmitted by the transfusion of blood products. The aim of this study is to analyze the complications of the hemophiliacs in Kosovo which have been treated with fresh frozen plasma, cryoprecipitate and concentrated products of FVIII and FIX. We have tested 75 patients with hemophilia A or B and there were used enzyme immunoassay test-Elisa method for the following: anti-HCV, HBsAg, HIV and TPHA.The serological data showed that HCV infection was positive in 29 cases or 38,7%, whereas infection with HBV and HIV were present in a smaller percentage of the patients (2,7% HBV and 1,4% for HIV). HCV infection was present only in 9,5% of the cases of the age group under 18 years. Infected hemophiliacs with one or two infective agents were found in 34,7%, respectively 4%. Infection with T. pallidum was present at none of the examined patients with hemophilia. HCV infection was higher in severe forms of hemophilia B (44,4%), compared with severe form of hemophilia A (30%).Based on our results, despite the infrequent application of FVIII and FIX concentrates, and other anti hemophilic preparations used in treating hemophilia patients, the number of infected hemophiliacs with blood-transmittable infectious agents was substantially high, especially with hepatitis C virus.

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

    Sailliol, A; Ausset, S; Peytel, E

    2010-12-01

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

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

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

    Purpose. Onset of transfusion-related acute lung injury (TRALI) is suggested to be a threshold-event. Data is lacking on the relation between titer of antibodies infused and onset of TRALI. We determined whether onset of TRALI is dependent on the titer of MHC-I antibodies infused in a combined model of ventilator-induced lung injury and antibody-induced TRALl. Methods. BALB/c mice were ventilated for five hours with low (7.5 ml/kg) or high (15 ml/kg) tidal volume. After three hours of MV, TRA...

  14. Role of RBCs alloimmunization in multiple transfused thalassaemia patients

    Amita Sagar Patel

    2016-03-01

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

    2000-01-01

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

    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.

    Full Text Available Viral hepatitis is an important public health threat for millions of people all over the world. Recently, some hepatitis viruses are detected. Hepatitis TT virus (TTV is an unenveloped virus with a single-stranded, circular DNA genome of 3,818-3,853 nucleotides (nt that infects humans and non-human primates (1. Recent reports indicate that TTV can be transmitted via blood/blood products (2. There are some previous reports on the prevalence of TTV-DNA among blood donors. The purpose of this study was to summarize the prevalence of TTV-DNA among transfusion-dependent thalassemia patients in the previous reports.This study was designed as a descriptive retrospective study. A literature review on the papers concerning the prevalence of TTV-DNA among transfusion-dependent thalassemia patients was performed. The author performed the literature review to find the report of the prevalence of TTV-DNA from database of the published works cited in the Index Medicus and Science Citation Index. The published works till August 2004 were reviewed. The reports without complete data, those not focusing on the transfusion-dependent thalassemia patients and those in a language other than English, were excluded and 4 literatures (3-6 were finally recruited. Of 290 documented transfusion-dependent thalassemia patients, there were 147 cases with TTV-DNA positivity. The summative percentage for TTV-DNA positivity was 50.7%. There is no significant association between the ethnicity of the donors and the TTV-DNA positivity (P>0.05. According to this study, the HGV infection seems to show no preference for a special ethnicity, implying the global importance of this hepatitis virus infection. The prevalence of TTV in multi-transfused thalassemics is more than that of blood donors (7, 8, implying the higher risk among the patients receiving blood transfusions.

  18. Transfusions of blood and blood products and viral infections

    Marta Wróblewska

    2002-06-01

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

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

  20. Occult hepatitis B virus infection and blood transfusion

    Seo, Dong Hee; Whang, Dong Hee; Song, Eun Young; Han, Kyou Sup

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

    Ali T Taher; Viprakasit, Vip; Khaled M. Musallam; Cappellini, M. Domenica

    2013-01-01

    Despite receiving no or only occasional blood transfusions, patients with non-transfusion-dependent thalassemia (NTDT) have increased intestinal iron absorption and can accumulate iron to levels comparable with transfusion-dependent patients. This iron accumulation occurs more slowly in NTDT patients compared to transfusion-dependent thalassemia patients, and complications do not arise until later in life. It remains crucial for these patients' health to monitor and appropriately treat their ...

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

  19. Impact of Transfusion on Cancer Growth and Outcome.

    Goubran, Hadi A; Elemary, Mohamed; Radosevich, Miryana; Seghatchian, Jerard; El-Ekiaby, Magdy; Burnouf, Thierry

    2016-01-01

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

  20. The use of big data in transfusion medicine.

    Pendry, K

    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. PMID:26178303

  1. Erythrocyte transfusion and calcium channel blockers: Effects on tumor radiosensitivity

    One approach to overcoming the radioresistance often associated with anemia is to give an erythrocyte transfusion prior to irradiation. When 0.5 ml packed erythrocytes were injected I.V. into anemic RIF-1 or SCCVII/St tumor bearing mice, just prior to X-rays, and tumor response was measured by an in vivo/in vitro survival assay, there was a 10-fold increase in cell killing in the RIF-1 tumor, compared to only a 4-fold increase for SCCVII/St. The differences in response to the treatments described may be related in part to the variation in normal hypoxic fraction, between the RIF-1 (20%) tumors. Calcium channel blockers have been shown to reduce the hypoxic fraction in some mouse tumors. Such compounds may therefore enhance the radiosensitivity produced by erythrocyte transfusion. One compound, cinnarizine, gave only a small enhancement of the radiation response in the RIF-1 tumor, compared to that for erythrocyte transfusion alone. Since the SCVII/St tumor has a greater hypoxic fraction, cinnarizine may give a greater enhancement of erythrocyte transfusion sensitization to X-rays than is observed in RIF-1 tumors. Additional results are presented and discussed with reference to adaptation to these treatments and the importance of the tumor hypoxic fractions

    Full Text Available Aim : The study was designed to find out the incidence of thrombocytopenia in leptospirosis and to correlate thrombocytopenia with other parameters like renal failure, hepatic failure and bleeding manifestation like adult respiratory distress syndrome and to assess the role of platelet transfusion. Materials and Methods : 50 cases of leptospirosis during the month of July and August 2005 were retrospectively analyzed. Criteria for selection were Lepto Tek Dri - dot test positive cases of the clinically suspected cases of Leptospirosis. Degree of thrombocytopenia was categorized as severe, moderate and mild. Presence of thrombocytopenia was clinically correlated with parameters like renal dysfunction, hepatic dysfunction and hemorrhagic manifestations (mainly ARDS. Role of platelet transfusion was assessed with reference to presence and degree of thrombcytopenia and hemorrhagic manifestations. Results : Out of total 50 patients 26 were male and 24 were females. Major bleeding manifestation in the form of ARDS was seen in 15 (30% of patients. 28 (56% patients had thrombocytopenia and 22 (44% patients had normal platelet counts. Total number of patients with renal dysfunction was 24 (48%. Only four (18.18% patients with normal platelet counts had renal dysfunction while 20 (71.42% patients with thrombocytopenia had renal dysfunction. Only two (9.09% patients with normal platelet counts and 48 (46.42% patients with thrombocytopenia had hepatorenal dysfunction. Total number of patients with ARDS was 15 (30%.

    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.

  4. Fulminant transfusion-associated graft-versus-host disease in a premature infant

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

  6. Platelet transfusion—the new immunology of an old therapy

    Moritz eStolla

    2015-02-01

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

    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.

    2015-01-01

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

    2003-01-01

    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.

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

    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.

    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.

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

    Full Text Available Introduction. Red blood cell antibodies may cause a positive result of pre-transfusion blood compatibility testing (crossmatch test. It can be a problem to provide suitable blood units for patients with clinically significant antibodies to high-frequency antigens as well as for those with multiple alloantibody specificities. This study was aimed at identifying transfused patients in the population of South-Backa who had developed clinically significant red blood cell alloantibodies. Material and methods. We analyzed the records of crossmatch results and antibody screening performed at the Blood Transfusion Institute of Vojvodina during 2012. Results. Antibodies were found in 103 patients: A 63 patients with single antibodies: 1 16 with antibodies of unknown specificity (3 autoantibodies, 13 alloantibodies; 2 39 with clinically significant antibodies (23 from Rh system (2 anti-C, 2 anti-D, 12 anti-E, 7 anti-c, 4 anti-K, 3 anti-Fya, 7 anti-Jka, 2 anti-S; 3 8 with usually not significant antibodies (6 anti-M, 1 anti-A1, 1 anti- Cw; B 40 patients developed multiple antibodies: 1 all patients had at least one clinically significant antibody from various blood group system (44 Rh, 13 Kell, 7 Kidd, 7 MNSs (S, s; 2 3 patients had usually not significant antibodies (1 Lewis, 2 Lutheran; 3 3 patients occasionally had clinically significant antibody (3 anti- Yta; 4 3 patients had antibodies of unknown specificity (2 autoantibodies, 1alloantibody. Antibodies detected in the majority of patients (65-63.1% had a specificity of Rh and/or the Kell system. Conclusions. The main goal of pre-transfusion blood compatibility testing is to detect clinically significant antibodies. The provision of antigen negative blood units for those patients is a special challenge for blood establishments. Database with a sufficient number of typed blood donors can help to resolve this problem.

    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 calves developed diarrhoea during the study and four were humanely euthanased due to progressive clinical deterioration. None of the calves in the CG showed signs of disease or died during the study. The dose of IgG used in this trial effectively provided an adequate sIgG concentration in 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.

    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.

    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.

  6. Thromboelastography-guided transfusion Therapy in the trauma patient.

    Brazzel, Charice

    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.

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

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

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

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

    Rajtar, Małgorzata

    2013-12-01

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

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

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

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

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

    2010-01-01

    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.

  3. Detection of rare blood group, Bombay (Oh phenotype patients and management by acute normovolemic hemodilution

    Manisha Shrivastava

    2015-01-01

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

Objectives: The aim of this study was to evaluate the practice of obstetric blood transfusion, the mean decision-transfusion interval, and the outcome in parturients who had blood transfusions. Methods: This was a prospective descriptive study conducted at the Federal Teaching Hospital, Abakaliki, South-East Nigeria, between 1st January, 2012 and 31st December, 2012. Statistical analysis was done using SPSS version 15.0 for Windows. Results: Out of 151 parturients who received blood transfusion, 141/151 (97.4% were knowledgeable about blood transfusion, while only 10/151 (2.6% had no knowledge of it. The hospital was the source of information for 120/151 (80.8% of the participants. Blood transfusion rate was 7.04% of all parturients. The mean decision-transfusion interval was 12.0 ± 4.3 hours. All participants were transfused with either whole blood or sedimented cells. The mean number of blood units transfused was 1.77 ± 0.93 units. The indications for transfusion were: anemia, 109/151 (72.2%; shock, 13/151 (8.6%; postpartum hemorrhage, 23/151 (15.2%; antepartum hemorrhage, 6 (4%. Six (4% women died; mortality was due to renal failure in 3/6 (50% and disseminated intravascular coagulopathy in 3/6 (50%. These deaths were due to delays and difficulty in securing blood for transfusion, while those who got transfused on time were salvaged with minimal morbidity, 21/151 (14%, or with no morbidity, 130/151 (86%. Conclusion: Excessive blood loss and anemia still

    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.

    2008-01-01

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

    Limited data exist on platelet transfusion during postpartum haemorrhage. We retrospectively analysed a consecutive cohort from a single centre of 347 women with moderate or severe postpartum haemorrhage, transfused according to national guidelines. Twelve (3%) women required a platelet transfusion. There were no differences between women who did and did not receive platelets with respect to age, mode of initiation of labour or mode of delivery. Women receiving a platelet transfusion had a lower median (IQR [range]) platelet count at study entry than women who did not receive platelets before haemorrhage (135 (97-175 [26-259])×10(9) .l(-1) vs 224 (186-274 [91-1006])×10(9) .l(-1) ), respectively), and at diagnosis of postpartum haemorrhage (median 114 (78-153 [58-238])×10(9) .l(-1) vs 193 (155-243 [78-762])×10(9) .l(-1) respectively). Six women were thrombocytopenic pre-delivery. The cause of haemorrhage that was associated with the highest rate of platelet transfusion was placental abruption, with three of 14 women being transfused. If antenatal thrombocytopenia or consumptive coagulopathy were not present, platelets were only required for haemorrhage > 5000 ml. Early formulaic platelet transfusion would have resulted in many women receiving platelets unnecessarily. Using current guidelines, the need for platelet transfusion is uncommon without antenatal thrombocytopenia, consumptive coagulopathy or haemorrhage > 5000 ml. We found no evidence to support early fixed-ratio platelet transfusion. PMID:27062151

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

  13. The radiographic appearances following adequate transfusion in β-thalassaemia

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

    2016-06-01

    This review addresses the physiology of monochorionic diamniotic (MC/DA) twins and the potential for twin-twin transfusion syndrome (TTTS). It focuses on the underlying cardiovascular pathophysiology of TTTS and the cardiovascular impact of TTTS for both the recipient and the donor twin. It explains the principles for assessment and monitoring of these cardiovascular changes and how these may be used to guide pregnancy management. Finally, it describes the effect of treatment on the altered hemodynamics and how this can influence pregnancy and perinatal management, as well as longer-term follow-up. PMID:27087122

  16. Effect of perioperative autologous versus allogeneic blood transfusion on the immune system in gastric cancer patients

    2007-01-01

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

  17. Asthma is a risk factor for acute chest syndrome and cerebral vascular accidents in children with sickle cell disease

    2005-01-01

    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.

  18. Facility-based constraints to exchange transfusions for neonatal hyperbilirubinemia in resource-limited settings.

    Mabogunje, Cecilia A; Olaifa, Sarah M; Olusanya, Bolajoko O

    2016-05-01

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

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

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

    2015-01-01

    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.

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

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

  4. Applying radio-frequency identification (RFID) technology in transfusion medicine.

    Hohberger, Clive; Davis, Rodeina; Briggs, Lynne; Gutierrez, Alfonso; Veeramani, Dhamaraj

    2012-05-01

    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. PMID:22079476

  8. Improvement in fresh frozen plasma transfusion practice: results of an outcome audit.

    Kakkar, N; Kaur, R; Dhanoa, J

    2004-06-01

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

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

    2002-09-01

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

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

The serological and clinical course suggests immunisation to passively transferred antigens without hepatitis....

  19. Feline transfusion practice in South Africa : current status and practical solutions : continuing education

    T. Dippenaar

    1999-07-01

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

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

  3. Impact of red blood cell transfusion on global and regional measures of oxygenation.

    Roberson, Russell S; Bennett-Guerrero, Elliott

    2012-01-01

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

    Myelodysplastic syndromes (MDS) are oligoclonal hematopoietic disorders characterized by peripheral cytopenias with anemias being the most prevalent feature. The majority of patients will depend on regular transfusions of packed red blood cells (PRBC) during the course of the disease. Particularly patients with MDS and low risk for transformation into acute myeloid leukemia and low risk of early death will receive PRBC transfusions on a regular basis, which puts them at high risk for transfusional iron overload. Transfusion dependence has been associated with negative impact on organ function and reduced life expectancy. Recently, several retrospective but also some prospective studies have indicated, that transfusion dependent patients with MDS might benefit from consequent iron chelation with regard to morbidity and mortality. However, low treatment adherence due to adverse events mainly gastrointestinal in nature is an important obstacle in achieving sufficient iron chelation in MDS patients. Here, we will summarize and discuss the existing data on Deferasirox in low risk MDS published so far and provide recommendations for optimal management of gastrointestinal adverse events during iron chelation aiming at improving treatment compliance and, hence, sufficiently removing excess iron from the patients.

Despite the good neurodevelopment, children classified at risk should be monitored for development throughout childhood.

  9. Basics of fluid and blood transfusion therapy in paediatric surgical patients

    Virendra K Arya

    2012-01-01

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

    2012-10-01

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

    Full Text Available Jose Mauro Kutner,1 Mariza Mota,1 Fabiana Conti,1 Lilian Castilho1,2 1Hemotherapy and Cell Therapy Department, Hospital Israelita Albert Einstein, São Paulo, SP, Brazil; 2Hemocentro Unicamp, Campinas, SP, Brazil Abstract: Blood transfusions are life sustaining in chronically transfused patients. However, certain complications, such as alloimmunization to red blood cells, can create challenges in the management of those patients. Routine phenotyping of blood recipients and the use of phenotype-matched blood units for transfusion have been useful to lower the occurrence of red cell alloantibodies in chronically transfused individuals. Nevertheless, extensive phenotyping is expensive, laborious, and cannot be performed in certain situations. The molecular understanding of blood groups has enabled the design of assays that may be used to better guide matched red blood cell transfusions. This review summarizes key findings related to red cell alloimmunization, the already identified and potential future benefits of blood group genotyping, and how molecular typing is being incorporated in the blood bank's routine to improve clinical and long-term outcomes in chronically transfused patients. Keywords: blood group genotyping, chronically transfused patients, platelet genotyping, RBC alloimmunization

    2016-01-01

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

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

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

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

    2016-01-01

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

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

  18. Ventilator associated pneumonia and transfusion, is there really an association? (the NAVTRA study

    Gonzalez Marco

    2006-07-01

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

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

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

    2005-07-01

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

  2. Survival and haematological recovery of children with severe malaria transfused in accordance to WHO guidelines in Kilifi, Kenya

    Idro Richard

    2008-12-01

    Full Text Available Abstract Background Severe anaemia requiring emergency blood transfusion is a common complication of malaria in children. To ensure access for urgent blood transfusion, the World Health Organization has developed clear guidelines with haemoglobin thresholds prevent unwarranted transfusion,. Few studies have reported outcome and haematological recovery of children with severe malaria where transfusion practice complies with WHO recommendations. Methods A prospective observational study of survivors of severe and complicated malaria transfused in accordance with WHO guidelines. Children were invited for review at one month post-discharge. Non-attendees were traced in the community to ascertain survival. Results Outcome was assessed in 213 survivors. Those transfused were younger, had a higher base deficit, mean lactate levels and a higher prevalence of respiratory distress. As expected mean admission haemoglobin (Hb was significantly lower amongst transfused [5.0 g/dL SD: 1.9] compared to non-transfused children [8.3 g/dL SD: 1.7] (p Conclusion This data supports the policy of rational use of blood transfusion, as proposed in the WHO guidelines, for children with anaemia in areas where access to emergency transfusion is not guaranteed. We have provided empirical data indicating that transfusion does not influence superior recovery in haemoglobin concentrations and therefore cannot be justified on this basis alone. This may help resolve the disparity between international policy and current clinical practice. Effective anti-malarial treatment at discharge may prevent reoccurrence of anaemia.

  3. Blood transfusion in cardiac surgery: Does the choice of anesthesia or type of surgery matter?

    Nešković Vojislava

    2013-01-01

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

  4. MRI Measurements of Iron Load in Transfusion-Dependent Patients: Implementation, Challenges, and Pitfalls.

    Quinn, Charles T; St Pierre, Tim G

    2016-05-01

    Magnetic resonance imaging (MRI) has played a key role in studies of iron overload in transfusion-dependent patients, providing insights into the relations among liver and cardiac iron loading, iron chelator dose, and morbidity. Currently, there is rapid uptake of these methods into routine clinical practice as part of the management strategy for iron overload in regularly transfused patients. Given the manifold methods of data acquisition and analysis, there are several potential pitfalls that may result in inappropriate decision making. Herein, we review the challenges of establishing suitable MRI techniques for tissue iron measurement in regularly transfused patients. PMID:26713769

  5. When less is more: can we abandon prophylactic platelet transfusion in Dengue fever?

    Kurukularatne, Changa; Dimatatac, Frederico; Teo, Diana Lt; Lye, David C; Leo, Yee Sin

    2011-12-01

    Dengue fever (DF) has several hematological manifestations including thrombocytopenia and increased bleeding risk. Prophylactic platelet transfusion-in the absence of major bleeding-is utilized in DF with thrombocytopenia with the intention of preventing hemorrhagic complications. However, prophylactic platelet transfusion in DF is neither standardized nor supported by clinical evidence. We conclude that risks, costs and poor resource utilization associated with prophylactic platelet transfusion in DF far outweigh any potential hematological benefit, and as such, should not constitute routine clinical practice. PMID:22294065

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

    Orkuma J.A

    2014-12-01

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

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

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

    2009-01-01

    BACKGROUND: Perioperative anemia leads to increased morbidity and mortality and potentially inhibits rehabilitation after hip fracture surgery. As such, the optimum transfusion threshold after hip fracture surgery is unknown. PATIENTS AND METHODS: A total of 120 elderly, cognitively intact hip...... fracture patients admitted from their own home were randomly assigned to receive transfusion at a hemoglobin threshold of 10.0 g per dL (liberal) versus 8.0 g per dL (restrictive) in the entire perioperative period. Patients were treated according to a well-defined multimodal rehabilitation program....... Primary outcome was postoperative functional mobility measured with the cumulated ambulation score (CAS). RESULTS: Patients in the liberal group received transfusions more frequently than those in the restrictive group (44 patients vs. 22 patients; p < 0.01) and received more transfusions during...

  13. MR marrow signs of iron overload in transfusion-dependent patients with sickle cell disease

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

  16. Brazilian Thalassemia Association protocol for iron chelation therapy in patients under regular transfusion

    Monica Pinheiro de Almeida Verissimo

    2013-01-01

    Full Text Available In the absence of an iron chelating agent, patients with beta-thalassemia on regular transfusions present complications of transfusion-related iron overload. Without iron chelation therapy, heart disease is the major cause of death; however, hepatic and endocrine complications also occur. Currently there are three iron chelating agents available for continuous use in patients with thalassemia on regular transfusions (desferrioxamine, deferiprone, and deferasirox providing good results in reducing cardiac, hepatic and endocrine toxicity. These practice guidelines, prepared by the Scientific Committee of Associação Brasileira de Thalassemia (ABRASTA, presents a review of the literature regarding iron overload assessment (by imaging and laboratory exams and the role of T2* magnetic resonance imaging (MRI to control iron overload and iron chelation therapy, with evidence-based recommendations for each clinical situation. Based on this review, the authors propose an iron chelation protocol for patients with thalassemia under regular transfusions.

  17. Rhesus Negative Woman Transfused With Rhesus Positive Blood: Subsequent Normal Pregnancy Without Anti D production.

    Maya, E T; Buntugu, K A; Pobee, F; Srofenyoh, E K

    2015-03-01

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

    2009-04-01

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

  3. Glucose-6-Phosphate Dehydrogenase-Deficiency in Transfusion Medicine: The Unknown Risks

    Francis, Richard O.; Jhang, Jeffrey S.; Pham, Huy P.; Hod, Eldad A.; Zimring, James C; Spitalnik, Steven L.

    2013-01-01

    The hallmark of glucose-6-phosphate dehydrogenase (G6PD) deficiency is red blood cell (RBC) destruction in response to oxidative stress. Patients requiring RBC transfusions may simultaneously receive oxidative medications or have concurrent infections, both of which can induce hemolysis in G6PD-deficient RBCs. Although it is not routine practice to screen healthy blood donors for G6PD deficiency, case reports identified transfusion of G6PD-deficient RBCs as causing hemolysis and other adverse...

    2013-01-01

    Background Preoperative donation of autologous blood has been widely used to minimize the potential risk of allogeneic transfusions in total knee arthroplasty. A previous study from our center revealed that preoperative autologous donation reduces the allogeneic blood exposure for anemic patients but has no effect for non-anemic patients. Questions/Purposes The current study investigates the impact of a targeted blood donation protocol on overall transfusion rates and the incidence of allogen...

  12. Transfusion related morbidity in premature babies: Possible mechanisms and implications for practice

    Collard, Keith James

    2014-01-01

    Many premature babies, especially those with a low birth weight are given multiple transfusions during their first few weeks of life. The major serious complications of prematurity include bronchopulmonary dysplasia, with lesser incidences of retinopathy of prematurity, intraventricular haemorrhage, and necrotising enterocolitis. Many studies have shown correlations between the receipt of blood transfusions and the development of these conditions, but little is known of the underlying pathoph...

  13. Prevalence and specificities of red cell alloantibodies in transfusion-dependent beta thalassemia patients in Yazd

    Vaziri, M.; JavadzadehShahshahani, H; Moghaddam, M.; Taghvaee, N

    2015-01-01

    Background Multiple transfusions in thalassemia patients may lead to antibody production against blood group antigens and hemolytic transfusion reaction might occur. In this study, antibody screening test was performed by tube and gel methods to determine the prevalence and specificity of alloantibodies in thalassemia patients. Materials and Methods In this cross-sectional study, overall of 100 thalassemia patients from Yazd thalassemia clinic were recruited from July to September 2013. Two b...

    Red blood cell alloimmunization is a common complication among the transfusion recipients. In Malaysia, multiple ethnicity causes genetic heterogeneity among the population which in turn can cause a wide variation of antibody. The objective of this study was to analyse the red cell alloantibody detected during the pre-transfusion testing. This was a cross-sectional study done in the blood bank of Universiti Kebangsaan Malaysia Medical Centre during the period of January–December 2010. The dat...

  15. IMPACT OF RED BLOOD CELL TRANSFUSION ON GLOBAL AND REGIONAL MEASURES OF OXYGENATION

    Roberson, Russell S.; Bennett-Guerrero, Elliott

    2012-01-01

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

    2015-01-01

    Background and study objectives Blood transfusion is central in the prevention and treatment of certain chronic complications of sickle cell disease. It is indispensible in correcting anaemias as well as in the practice of exchange blood transfusion. These gains are largely limited by formation of allo-antibodies. Several studies demonstrated varying frequencies of allo-immunization in various patient groups. The effect of the racial differences between the donor and recipient pool, which has...

  18. Granulocyte transfusions in recovery of neutropenic rats from induced E. coli toxicemia.

    Popovic, V; Schaffer, R; Popovic, P

    1977-05-01

    Rats made transiently neutropenic by intra-arterial administration of vinblastine (3 mg/kg) and infected with E. coli (6.02+/-0.45 X 10(8), per animal) have a mortality rate of 90% within 48 h post infection. Multiple transfusions of large numbers of granulocytes (harvested from Deca-Durabolin treated donor rats) protected the neutropenic animals from sepsis. Out of a group of 11 rats, 10 recovered completely after repeated granulocyte transfusions. PMID:326570
