DAT should be performed, although it can be negative in case of rapid clearance of isohemagglutinin-loaded recipient RBCs. Depending on the specificity, alloantibodies responsible for the delayed transfusion reaction activate in characteristic tests, for example, antibodies from the Rh system react in an enzymatic test, often also in anti-globulin testing. Features of late hemolytic transfusion reaction and time of their occurrence [21]. Positive reactions with allogeneic blood cells are accompanied by positive auto control of the patients red blood cells. Laboratory testsmainly serologicalare crucial for the diagnosis of an early haemolytic reaction. Autoimmune hemolytic anemia. Transfusion reactions (TRs) occurring during inpatient admissions (excluding emergency room and outpatient visits) from 1/1/2010-31/12/2015 were included. 0000001590 00000 n Then intravascular haemolysis coincides with visible haemoglobinuria [40, 41]. The reaction is most severe in the case of antigens A and B, because their number is estimated at about 5 105 per cell [12, 13]. Positive DAT with anti-IgG and anti-C3d reagents may persist for several months [9]. Post-transplant AIHA is often therapy resistant and associated with decreased survival. The C5b-8 complexes create holes in the cell membrane that increase when exposed to the C9 component. There are several causes. Clinically significant differences between the above mechanisms of red blood cells destruction are based on the time of onset of haemolysis and the destruction rate of red blood cells. Complement activation appears to be the most important determining factor in these cases. By Osaro Erhabor, Tosan Erhabor, Teddy Charles Adias By Vivian Gonzaga, Bruna Policiquio, Cristiane Wences By Vernica Valdivieso-Gmez, Javier Garrancho-Prez, IntechOpen Limited Laboratory tests show anaemia, increased LDH and bilirubin, decreased haptoglobin and higher white blood cell counts in post-transfusion haemolytic reactions. Although infrequent, non-immune transfusion reactions, including haemolysis, transfusion-associated sepsis, and circulatory overload, should be considered in the differential diagnosis. 0000002464 00000 n This concentration may be responsible for causing a haemolytic reaction [50]. Specificity of selected antibodies associated with haemolytic transfusion reactions. startxref CLL indicates chronic lymphocytic leukemia; CVID, common variable immunodeficiency syndrome; G6PD, glucose-6-phosphate dehydrogenase; GVHD, graft-versus-host disease; PNH, paroxysmal nocturnal hemoglobinuria; and SAA, severe aplastic anemia. While interpreting the obtained test results, it should be kept in mind that haemolysis or shortening the survival time of red blood cells can be caused by non-immunological factors, for example, adding hypotonic fluids to red blood cells, inefficient heating or freezing devices, etc. ?:0FBx$ !i@H[EE1PLV6QP>U(j WebHemolytic disease of the newborn (also known as HDN or erythroblastosis fetalis) Rh D hemolytic disease of the newborn (also known as Rh disease) ABO hemolytic disease of the newborn (the direct Coombs test may only be weakly positive) Anti-Kell hemolytic disease of the newborn Rh c hemolytic disease of the newborn EdwardB. Flink; The Distinction of Hemolytic and Nonhemolytic Transfusion Reactions. 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]. Post-reaction LOS was longer by a median of 5 or 7 days for NH-DSTR versus non-anti-RBC TRs and other anti-RBC TRs respectively. The evaluation of haptoglobin and free hemoglobin in serum and urine can be helpful. Table 5 presents features of delayed haemolytic transfusion reaction and the time of their occurrence. Acute reactions occur within 24 hours of transfusion and include acute haemolytic, febrile non-haemolytic, allergic, and transfusion-related acute lung injury (TRALI). However, in those with non-hemolytic delayed serologic transfusion reactions (NH-DSTRs), the threat applies more towards the future rather than the present time. Low concentration cytokines include IL-1, IL-6 and TNF-. A report issued by the Quebec Haemovigilance System covering 5 years of observation described 47 ABO incompatibility reactions, 55 cases of acute haemolytic transfusion reaction and 91 cases of delayed transfusion reaction in reference to 7059 all reported transfusion reactions. Minor ABO-incompatible HSCT is characterized by the transfer of donor isohemagglutinins directed against the recipient's RBC antigens. The presence of fibrinogen degradation products from an absorbing haematoma can be interpreted as a DIC symptom. These errors are the most common cause of ABO incompatible transfusions, threatening the patients life. 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]. By Osaro Erhabor, Tosan Erhabor, Teddy Charles Adias and Iwueke Ikechukwu Polycarp. Since IL-1 and IL-6 affect proliferation and differentiation of -lymphocytes, the synthesis of these two cytokines enhances the synthesis of allo- and autoantibodies, which are often involved in the formation of delayed haemolytic transfusion reaction [1, 24, 25]. To understand that hemolytic anemia (HA) is frequent after hematopoietic stem cell transplantation (HSCT), To discuss different etiologies of HA during and after allogeneic HSCT, To know how to approach and investigate HA in this situation for an accurate diagnosis, To know the prophylactic measures to reduce the extent of hemolysis in case of ABO-incompatible HSCT and to know currently available therapeutic options, To know the special transfusion requirements of patients before, during, and after HSCT, implying a close collaboration between clinicians, transplant physicians, and transfusion services. Features of antibodies (specificity, class and heat amplitude) and antigens (density of antigenic sites and their distribution) against which the antibodies directed are interconnected. DAF regulates C3a-converting activity. Blood clots that form in the renal arterioles cause cortical kidney attacks. Table 8 presents changes in laboratory indicators in transfusion haemolytic reactions [56]. found that, using current laboratory methods, 25% of red blood cell antibodies become indeterminate on average after about 10months from production [43]. Anemia, reticulocytopenia, and a bone marrow lacking erythroid precursors are clues for the diagnosis of PRCA in the setting of major ABO-incompatible HSCT. However, transfusion requirement in acute AIHA can be a medical emergency and must not be delayed as RBC transfusions can be lifesaving. We also refer to other sources.2-4 Drug-induced HA should always be considered, especially due to antimicrobial agents (eg, dapsone, penicillins, and cephalosporins) and immunosuppressants [calcineurin-inhibitors and sirolimus, which are the most frequently used drugs for graft-versus-host disease (GVHD) prophylaxis].5 Hemolysis due to passive transfer of antibodies from a high-titer type O blood product and hemolytic transfusion reactions (acute and delayed) following transfusion errors or due to non-ABO-RBC alloantibodies need to be excluded. Hematopoietic stem cell transplantation (HSCT) is unique because it is performed across the ABO blood group barrier. A negative DAT result does not exclude haemolysis, it may mean that the transfused blood cells have been destroyed by alloantibodies or the method used is not very sensitive. The number of reported cases of delayed haemolytic transfusion reaction was higher than in 2016, but comparable with previous years [6]. 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. 0000007661 00000 n We follow the timeline of the transplantation process and discuss investigations, differential diagnosis, and prophylactic measures including graft processing to avoid hemolysis in case of ABO incompatibility. They are destroyed by the complement system, although they did not participate directly in the antigen-antibody reaction. Diagnosis of post-transplant AIHA has to be distinguished from disease relapse, graft failure, drug- and treatment-related toxicity, infection, and GVHD. A panel of standard cells should contain clinically important antigens in a homozygous form to detect the presence of weak antibodies. The distribution of TRs (Figure 1) included 562 (71.8%) non-anti-RBC TRs and 221 (28.2%) anti-RBC TRs. The occurrence and severity of individual clinical symptoms can vary widely and are often non-specific [1, 8]. In case of immune-mediated hemolysis, a direct antiglobulin test (DAT), elution (also against a non-O RBC panel in case of ABO incompatibility), isohemagglutinin titration, and absorption techniques are required. Various malignant and nonmalignant diseases are associated with immune-mediated or nonimmune hemolysis. Delayed haemolytic transfusion reactions are well tolerated by most patients. Detection of a specific antigen on the donors blood cells is the confirmation that the detected alloantibodies were responsible for the haemolytic transfusion reaction. Outcomes included length of stay (LOS), interval between TR recognition and discharge, severity of TR (as per the International Society of Blood Transfusion grading system), and death. In rare cases, the result of transfusion alloimmunity in DHTR may be the production of autoantibodies (warm IgG autoantibodies or cold autoagglutinins). [60] compared the sensitivity of DAT performed by technique using monospecific IgG antiglobulin, flow cytometry and antibody elution. It enforces the introduction of procedures eliminating further errors. Intravascular haemolysis is characterised by the destruction of red blood cells at a rate of about 200ml of transfused cells within 1h of transfusion. This is defined as a combination of both major and minor ABO incompatibilities along with the risk of their consequences, and thus clinicians have to be aware of all the above-described complications. In contrast, extravascular haemolysis is less dramatic, with a rate of destruction of red blood cells of approximately 0.25ml/h/1kg of recipients body weight. Alloantibody testing should be performed in the intermediate antiglobulin test (IAT) and enzyme test. 0000004992 00000 n ??accessibility.screen-reader.external-link_en_US?? A and B antigens are highly immunogenic. FNHTR manifests as fever and/or chills without 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]. One of them was the use of improved techniques for detecting clinically relevant alloantibodies, which reduce the number of haemolytic transfusion reactions observed in blood recipients. Udani etal. Hemolysis during and after HSCT can occur at different time points, ie, even weeks or months after transplantation, and may have several causes (Figure 1). Monitoring for clinical and laboratory signs of hemolysis is mandatory and in case of massive hemolysis frequent hemoglobin measurements should be performed. However, they are listed in Table 1. Thus, in large clinical centres, where severely ill patients are treated, more of these events are recorded [4]. Suggested transfusion guidelines for patients undergoing ABO-incompatible HSCT6,8. Bidirectional ABO incompatibility: combination of both major and minor ABO incompatibilities. Usually, plasma alloantibodies are detectable at 47days after the transfusion and reach maximum activity between 10 and 15days after the transfusion. Delayed red cell engraftment due to host anti-donor isohemagglutinins may occur. We thank Andreas Buser and Jrg Halter for critically reviewing the manuscript. As opposed to other reviews of HAs, most often structured according to the pathophysiology of the hemolysis (ie, immune vs nonimmune), in this review, we have followed the timeline of the transplantation process and have discussed the investigation, differential diagnosis, and management at the time points during transplantation when HA most commonly occur. Acute haemolytic transfusion reactions are most often the result of clerical error. In comparison extravascular haemolysis is called delayed haemolytic transfusion reaction and usually occurs 24h or days after the end of the transfusion. CXCL8 primarily activates neutrophils, which leads to the accumulation of leukocytes in the lung vessels of small diameter and damage to the endothelium of blood vessels and their higher permeability [1, 12]. However, in those with non-hemolytic delayed serologic transfusion reactions (NH-DSTRs), the threat applies more towards the future rather than the present time. In addition, hypertension and proteinuria can be the early signs of TA-TMA, although these manifestations are encountered frequently in patients after HSCT.26,27,34,35 Soluble membrane attack complex (sC5b-9) may be elevated and is associated with a poor prognosis.30 Diagnosis can be confirmed by renal biopsy, which shows typical histologic findings, although there is little correlation between clinical and pathologic diagnosis. For this purpose, specific polymerase chain reaction from bone marrow specimens is considered to be a standard. The increase in cytokine release may also be due to the interaction of Fc R1 receptors with IgG molecules associated with red blood cells. Thus, clinical relevant and serious acute hemolytic reactions immediately after graft infusion are rare. How do I approach ABO-incompatible hematopoietic progenitor cell transplantation? Additional fluid and diuretic therapy are usually not necessary.
