In different people, antibodies with a particular specificity most often occur in the same class of immunoglobulins and have a similar heat amplitude, for example, anti-A, anti-B and anti-AB from the ABO system often belong to both IgM and IgG classes, they bind complement and have an extended thermal amplitude of up to 37C. In summary, awareness of possible complications after ABO-incompatible HSCT and early recognition and institution of appropriate measures are essential. The haemolytic transfusion reactions may have a different immunological origin than the reactions of antibodies in the recipients blood and the antigen present on the donors blood cells. In comparison extravascular haemolysis is called delayed haemolytic transfusion reaction and usually occurs 24h or days after the end of the transfusion. If negative results persist, the test should be repeated after a week and after 2 weeks, as in some patients, the antibodies may have been consumed to destroy transfused incompatible red blood cells. The recipients body immediately begins to destroy the donated red blood cells resulting in fever, pain, and sometimes severe complications such as kidney failure. A delayed hemolytic transfusion reaction occurs when the recipient develops antibodies to red blood cell antigens between 24 hours and 28 days after a transfusion. Primarily, calcineurin inhibitors and/or sirolimus should be reduced in dose or discontinued if alternative drugs for the prevention or treatment of GVHD can be administered (eg, steroids, mycophenolate mofetil). I think the LI part of TRALI refers to the fact that it sometimes presents like an ARDS type picture. The introduction of haemovigilance transfusiological surveillance systems has enabled the analysis of all fatal and severe transfusion reactions. The prevention of renal failure is aided by an early prevention of hypotension. Immune hemolytic transfusions reactions occur due to mismatch or incompatibility of Minor ABO-incompatible HSCT is characterized by the transfer of donor isohemagglutinins directed against the recipient's RBC antigens. In contrast to solid organ transplantation, donor-recipient ABO incompatibility is not an impediment for HSCT and occurs in 30%-50% of transplants.7,8 In major ABO-incompatible HSCT, the patient has preformed antibodies (ie, isohemagglutinins) against A and/or B antigens expressed on the donor's RBC. 0000007661 00000 n A new paradigm: diagnosis and management of HSCT-associated thrombotic microangiopathy as multi-system endothelial injury, Risk factors and severe outcome in thrombotic microangiopathy after allogeneic hematopoietic stem cell transplantation, Vascular endothelium as novel target of graft-versus-host disease, Thrombotic complications after haematopoietic stem cell transplantation: early and late effects, Diagnostic criteria for hematopoietic stem cell transplant-associated microangiopathy: results of a consensus process by an International Working Group, Thrombotic thrombocytopenic purpura-hemolytic uremic syndrome following allogeneic HPC transplantation: a diagnostic dilemma, Hematopoietic stem cell transplant-associated thrombotic microangiopathy: review of pharmacologic treatment options, Use of eculizumab in patients with allogeneic stem cell transplant-associated thrombotic microangiopathy: a study from the SFGM-TC, Transplant-associated microangiopathy (TAM) in recipients of allogeneic hematopoietic stem cell transplants, Drug-induced thrombotic microangiopathy: a systematic review of published reports, Acute graft-versus-host disease: a bench-to-bedside update, Thrombotic microangiopathy in blood and marrow transplant patients receiving tacrolimus or cyclosporine A, Management of autoimmune diseases after haematopoietic stem cell transplantation, Secondary autoimmune diseases occurring after HSCT for an autoimmune disease: a retrospective study of the EBMT Autoimmune Disease Working Party, New autoimmune diseases after cord blood transplantation: a retrospective study of EUROCORD and the Autoimmune Disease Working Party of the European Group for Blood and Marrow Transplantation, Autoimmune hemolytic anemia following allogeneic hematopoietic stem cell transplantation in adult patients, Autoimmune hematological diseases after allogeneic hematopoietic stem cell transplantation in children: an Italian multicenter experience, Autoimmune hemolytic anemia after allogeneic hematopoietic stem cell transplantation: analysis of 533 adult patients who underwent transplantation at King's College Hospital, Severe cold agglutinin disease caused by recurrent monomorphic Epstein-Barr virus (EBV)-associated post-transplant lymphoproliferative disorder (PTLD), clonally related to an EBV-negative plasmacytic hyperplasia in a pediatric multivisceral organ transplant recipient. Pyruvate kinase deficiency. Microangiopathic HA is characterized by the presence of anemia, low platelets, and schistocytes in a blood smear. Febrile nonhemolytic transfusion reactions (FNHTRs) are common, occurring with 13% of transfusions. In ABO incompatibility, in which anti-A, anti-B and anti-AB antibodies activate complement leading to intravascular haemolysis, a large amount of tumour necrosis factor- (TNF) and interleukins CXCL8 (IL-8) and CCL2 are released into the plasma (MCP-1) [19, 20, 21]. Hemolysis in DHTR can be severe, because both the transfused and autologous red blood cells may be destroyed (so-called bystander hemolysis); DHTR trailer Complement system abnormalities including regulatory defects and autoantibodies against factor H have been described, which suggests a possible role of complement in the disease process. Prompt recognition of an immune-mediated transfusion reaction is fundamental to improving patient outcome. The distribution of TRs (Figure 1) included 562 (71.8%) non-anti-RBC TRs and 221 (28.2%) anti-RBC TRs. TRALI can be delayed by a few hours. In addition, their degradation products (fibrinogen/fibrin degradation products (FDP)) resulting from the breakdown of fibrinogen and fibrin exhibit anticoagulant properties, inhibit platelet function, act as cytotoxic vascular endothelium and increase capillary permeability, further disrupting haemostasis mechanisms [26]. These reactions can occur acutely or in a delayed timeframe, while the sensitizing antibody may derive from the host or be passively acquired. If a haemolytic transfusion reaction is suspected, medical personnel should immediately stop transfusing a blood component. Attempts have been made to use high doses of intravenous immunoglobulins to prevent haemolytic reactions in patients who have been immunised for winter and for whom compatible red blood cells have not been selected [63]. Anti-A, anti-B and anti-AB antibodies are involved in causing an early intravascular transfusion reaction, and transfusion of incompatible blood in the ABO system poses a threat to the recipients life, especially when group A red blood cells are transfused to a patient with group O.Sixty-one (61%) of all haemolytic transfusion-related fatal reactions are associated with the ABO incompatibility [38, 39]. Proinflammatory cytokines affect blood coagulation and fibrinolysis, for example, TNF- and IL-1 increase TF expression and inhibit thrombomodulin (TM) expression on vascular endothelial cells [28]. In two countries, Sweden and Finland, which have implemented national identification systems, this frequency was 1 for 1986 samples [61]. Conflict-of-interest disclosure: Holbro has received research funding from CSL Behring and Novartis, and has consulted for Teva and Amgen; and Passweg declares no competing financial interests. When examining recipient red blood cells using a diagnostic reagent with a specificity corresponding to alloantibodies detected in the patient, mixed agglutination is observed, which indicates the presence of two blood cell populations in the patients circulation. Further studies to better understand the pathophysiology of TA-TMA are needed. However, there is a danger of bleeding. Search for other works by this author on: 2016 by The American Society of Hematology. Books > Donors are screened for alloantibodies. This phenomenon is called delayed serologic transfusion reaction (DSTR) and should be differentiated from delayed haemolytic transfusion reaction [9]. Historical research results indicate that the frequency of haemolytic transfusion reactions falls between 1:10,000 and 1:50,000 transfused blood components [3, 4]. Hematopoietic stem cell transplantation (HSCT) is a potentially curative and increasingly used treatment approach for different malignant and nonmalignant diseases, including entities associated with HA, such as chronic lymphocytic leukemia with autoimmune HA (AIHA), paroxysmal nocturnal hemoglobinuria, and sickle cell disease.1 HA can develop after HSCT; however, HSCT can still be considered for the treatment of severe, therapy-resistant AIHA. DHTR can be identified in these patients by the presence of antigen on the transfused red blood cells to which the antibodies may be directed. Table 6 presents the differential diagnosis of haemolytic transfusion reactions. Delayed reactions occur days to weeks after the transfusion and include delayed haemolytic transfusion reactions, transfusion-associated graft-versus-host disease, and post-transfusion purpura. WebFebrile Non-Hemolytic Transfusion Reaction (FNHTR): FeverOR chills and rigors occurring within 4 hours of transfusion.Signs and symptoms include fever (greater than or equal to38C/100.4F oral and a change of at least 1C/1.8F) frompre-transfusion value) or chills/rigors.Acute Hemolytic Transfusion Reaction (AHTR): Hemolysisoccurring within Haemoglobinemia is not diagnosed in the serum of these patients due to jaundice, often direct antiglobulin reaction (DTA) is positive and elevated bilirubin and LDH are found. In addition, every HSCT candidate, as well as the corresponding donor, can have additional conditions leading to HA (eg, glucose-6-phosphate dehydrogenase deficiency). It is known that a significant proportion of NO does not immediately bind to HbFe2+heme, instead it binds to cysteine, resulting in the formation of the S-nitrosothiol derivative Hb (SNO-Hb). Haemolytic post-transfusion reaction is caused by accelerated destruction of erythrocytes by immunological incompatibility between the donor and the recipient. It is mainly haemolysis that is responsible for the destruction of transfused donor blood cells by antibodies present in the recipient, but in rare cases, destruction may be caused in recipient blood cells by donor antibodies present in transfused plasma or platelet concentrate [1]. Particular attention should be paid to the patients circulation. Most data come from retrospective studies that do not include reactions not reported by clinicians. Our team is growing all the time, so were always on the lookout for smart people who want to help us reshape the world of scientific publishing. Therefore, discussion of immune and nonimmune causes of hemolysis follows the chronological order of transplantation, and management of blood group incompatibility is discussed before transplantation-associated thrombotic microangiopathy (TA-TMA) and this before post-transplant AIHA. Moreover, new drug developments for prophylaxis and therapy of GVHD will perhaps avoid drug-induced TMA. Table 8 presents changes in laboratory indicators in transfusion haemolytic reactions [56]. The results of these studies indicate a critical role of monocyte activation in the development of intravascular haemolytic transfusion reaction [15]. The most common reaction among the acute (approximately 30%) was haemolysis resulting from ABO incompatibility [5]. A and B antigens are highly immunogenic. Features of antibodies (specificity, class and heat amplitude) and antigens (density of antigenic sites and their distribution) against which the antibodies directed are interconnected. WebTransfusion Reactions Also known as AHTR (acute hemolytic transfusion reaction) DHTR (delayed hemolytic transfusion reaction) FNHTR (febrile non-hemolytic Hemolysis can be severe, even fatal, and persists until all the recipient RBCs are replaced by transfused or donor-derived RBCs. This phenomenon occurs in patients with sickle cell disease [44, 45, 46]. Intravascular haemolysis modulates blood pressure and local blood flow through changes in the metabolism of the physiological vasodilatornitric oxide (NO). To which extent the above-mentioned immunosuppressants are directly responsible for or sustain TA-TMA remains speculative. EdwardB. Flink; The Distinction of Hemolytic and Nonhemolytic Transfusion Reactions. The key pathogenetic phenomenon in DIC is excessive thrombin generation in the tissue factor (TF)-dependent pathway and activated factor VII (FVIIa-activated factor VII) [26]. Haemoglobin released from red blood cells also reacts nephrotoxically with nitric oxide (NO), damaging the epithelial cells of the renal tubules and the stroma that remains after their breakdown [33, 34]. Bidirectional ABO incompatibility: combination of both major and minor ABO incompatibilities. /Producer (Apache FOP Version 1.0) AH indicates acute hemolysis; AIHA, autoimmune hemolytic anemia; BM, bone marrow; CB, cord blood; CBC, complete blood count; CLL, chronic lymphocytic leukemia; CVID, common variable immunodeficiency; D, donor; DAT, direct antiglobulin test; DIC, diffuse intravascular coagulation; DIHA, drug-induced HA; LDH, lactate dehydrogenase; PBSC, periphereal blood stem cells; PLS, passenger lymphocyte syndrome; Plt, platelets; PNH, paroxysmal nocturnal hemoglobinuria; PRCA, pure red cell aplasia; PTLD, post-transplant lymphoproliferative disease; R, recipient; Rc, reticulocytes; SAA, severe aplastic anemia; and TMA, thrombotic microangiopathy. In all these cases, haemolysis takes place via the classical pathway of complement activation. The presence of fibrinogen degradation products from an absorbing haematoma can be interpreted as a DIC symptom. It is probably the result of direct stimulation of nociceptive nerves in perivascular tissue by bradykinin, which, in turn, is released during sudden activation of complement [37]. Disturbances deemed unrelated to transfusion were excluded. In case of relapse, isohemagglutinins produced from surviving recipient plasma cells can drive HA through destruction of donor RBCs. An acute hemolytic reaction occurs during or shortly after the transfusion (we give some products pretty quickly depending on the case). { 13 Less common signs and symptoms include flushing, lower back If positive results indicate alloantibodies are present, they should be identified. This varies depending on the graft source, as bone marrow contains more RBCs compared with peripheral blood progenitor cells (PBSCs) collected by apheresis and cord blood (CB). [62]. Antibodies capable of destroying transfused blood cells are called clinically relevant antibodies, and the transfusion reaction in the event of immunological incompatibility depends on: (1) specificity of antibodies; (2) thermal amplitude of the antibodies; (3) IgG classes and IgG subclasses; (4) number, density and spatial configuration of antigenic sites on red blood cells; (5) the ability of antibodies to activate the complement system; (6) plasma concentrations of antibodies and (7) volumes of transfused red blood cells. 0000001054 00000 n Catheterisation of the pulmonary artery helps to monitor the situation. Alloantibodies responsible for haemolysis, needle diameter too small, haematocrit of transfused red blood cells too high, an inappropriate method of freezing/thawing red blood cells, mechanical damage to blood cells, artificial valves, Drug-induced haemolysis of red blood cells. The C3b and C3d components bind with the red blood cell membrane and in many cases the complement cascade process ends. The underlying disease, drugs (particularly those used for conditioning and immunosuppressants), infections, graft-versus-host disease, and autoimmune diseases may all contribute to the clinical and laboratory picture of HA. Positive reactions with allogeneic blood cells are accompanied by positive auto control of the patients red blood cells. 5 0 obj It is a benign occurrence with symptoms that include fever but Febrile non-hemolytic transfusion reaction (FNHTR) Febrile non-hemolytic transfusion reactions are the most common reaction reported after a transfusion. FNHTR is characterized by fever or chills in the absence of hemolysis (breakdown of red blood cells) occurring in the patient during or up to 4 hours after a transfusion. In approximately 11% of cases, more than one antibody specificity is detected. [60] compared the sensitivity of DAT performed by technique using monospecific IgG antiglobulin, flow cytometry and antibody elution. Reduced haptoglobin levels usually occur in both types of haemolysis. stream They activate the complement system to the stage of binding of the C3b component, causing extravascular haemolysis. How do I approach ABO-incompatible hematopoietic progenitor cell transplantation? /Length 11 0 R In case of preformed alloantibodies (through transfusions or pregnancy) and a major RhD incompatibility, delayed HA may result.

Diagnosis of post-transplant AIHA has to be distinguished from disease relapse, graft failure, drug- and treatment-related toxicity, infection, and GVHD. %PDF-1.4 It should be noted that an increase in body temperature and white blood cell count, typical for DHTR, can be interpreted as a sign of infection. Lua antigens have uneven distribution on red blood cells and are weakly immunogenic. Ness etal. Anemia, reticulocytopenia, and a bone marrow lacking erythroid precursors are clues for the diagnosis of PRCA in the setting of major ABO-incompatible HSCT. The basic serological examination consists of direct antiglobulin testing (DAT); determination of blood group and RhD in donor and recipient; repetition of the serological compliance test. In contrast, the incidence for patients receiving a transfusion is estimated to be higher (about 1:5001:800 patients) because most recipients receive more than one blood unit. Infections, which occur frequently in HSCT recipients as a consequence of their disease, conditioning, and immunosuppression, may play an additional role in the pathogenesis of post-transplant ADs.42. In general, AD can affect every organ and occur alone or in combination.42 Autoimmune cytopenias after HSCT (including AIHA, immune thrombocytopenia, and immune neutropenia, or a combination of them) occur frequently.45-47 Incidence ranges from 1.3% to 4.4% and the risk factors for the development of AIHA are transplantation from an unrelated donor, development of chronic GVHD and a nonmalignant primary disease.45 Disease course is variable, ranging from spontaneous remissions to life-threatening and even fatal hemolysis.
