An antigenic mismatch between donor and recipient blood. Antibodies present in the recipient's serum may be directed against antigens in the donor product. Such a mismatch may result in a transfusion reaction in which, for example, donor blood is hemolyzed. (From Saunders Dictionary & Encyclopedia of Laboratory Medicine and Technology, 1984).
The major human blood type system which depends on the presence or absence of two antigens A and B. Type O occurs when neither A nor B is present and AB when both are present. A and B are genetic factors that determine the presence of enzymes for the synthesis of certain glycoproteins mainly in the red cell membrane.
A test to detect non-agglutinating ANTIBODIES against ERYTHROCYTES by use of anti-antibodies (the Coombs' reagent.) The direct test is applied to freshly drawn blood to detect antibody bound to circulating red cells. The indirect test is applied to serum to detect the presence of antibodies that can bind to red blood cells.
Yellow discoloration of the SKIN; MUCOUS MEMBRANE; and SCLERA in the NEWBORN. It is a sign of NEONATAL HYPERBILIRUBINEMIA. Most cases are transient self-limiting (PHYSIOLOGICAL NEONATAL JAUNDICE) occurring in the first week of life, but some can be a sign of pathological disorders, particularly LIVER DISEASES.
Sets of cell surface antigens located on BLOOD CELLS. They are usually membrane GLYCOPROTEINS or GLYCOLIPIDS that are antigenically distinguished by their carbohydrate moieties.
Erythrocyte isoantigens of the Rh (Rhesus) blood group system, the most complex of all human blood groups. The major antigen Rh or D is the most common cause of erythroblastosis fetalis.

Serious hazards of transfusion (SHOT) initiative: analysis of the first two annual reports. (1/234)

OBJECTIVE: To receive and collate reports of death or major complications of transfusion of blood or components. DESIGN: Haematologists were invited confidentially to report deaths and major complications after blood transfusion during October 1996 to September 1998. SETTING: Hospitals in United Kingdom and Ireland. SUBJECTS: Patients who died or experienced serious complications, as defined below, associated with transfusion of red cells, platelets, fresh frozen plasma, or cryoprecipitate. MAIN OUTCOME MEASURES: Death, "wrong" blood transfused to patient, acute and delayed transfusion reactions, transfusion related acute lung injury, transfusion associated graft versus host disease, post-transfusion purpura, and infection transmitted by transfusion. Circumstances relating to these cases and relative frequency of complications. RESULTS: Over 24 months, 366 cases were reported, of which 191 (52%) were "wrong blood to patient" episodes. Analysis of these revealed multiple errors of identification, often beginning when blood was collected from the blood bank. There were 22 deaths from all causes, including three from ABO incompatibility. There were 12 infections: four bacterial (one fatal), seven viral, and one fatal case of malaria. During the second 12 months, 164/424 hospitals (39%) submitted a "nil to report" return. CONCLUSIONS: Transfusion is now extremely safe, but vigilance is needed to ensure correct identification of blood and patient. Staff education should include awareness of ABO incompatibility and bacterial contamination as causes of life threatening reactions to blood.  (+info)

ABO blood group antigens on human plasma von Willebrand factor after ABO-mismatched bone marrow transplantation. (2/234)

von Willebrand factor (vWF) is synthesized exclusively by endothelial cells and megakaryocytes, and stored in the intracellular granules or constitutively secreted into plasma. ABO blood group antigens are covalently associated with asparagine-linked sugar chains of plasma vWF. The effect of ABO-mismatched bone marrow transplantation (BMT) or blood stem cell transplantation (BSCT) on the expression of ABO blood group antigens on the vWF was examined to obtain information on the origin of these antigens. In ABO-mismatched (HLA-matched) groups, 8 cases of BMT and 4 cases of BSCT were examined. In all cases, the ABO blood groups on red blood cells were gradually converted to the donor's type within 80 to 90 days after the transplantation. The blood group antigens on the vWF were consistent with the recipient's blood group for the period monitored by enzyme-linked immunosorbent assay (ELISA). When vWF was isolated from normal platelets and examined for the blood group antigens using ELISA or immunoblotting, it showed few antigens. However, vWF extracted from veins expressed blood group antigens. These findings indicate that platelet (megakaryocyte)-derived vWF does not contain blood group antigens and that these antigens may be specifically associated with vWF synthesized in endothelial cells and secreted into plasma. Furthermore, it is possible that the persistence of the recipient's blood group antigens on plasma glycoproteins such as vWF, independent of the donor-derived erythrocytes, after ABO-mismatched stem cell transplantation, may influence the immunological system in the production of anti-blood group antibodies resulting in the establishment of immunological tolerance in the recipient plasma.  (+info)

Perinatal risk factors for childhood type 1 diabetes in Europe. The EURODIAB Substudy 2 Study Group. (3/234)

OBJECTIVE: To explore whether perinatal factors are associated with the development of childhood type 1 diabetes. RESEARCH DESIGN AND METHODS: We studied hospital records from 892 cases of childhood type 1 diabetes compared with 2,291 population-based control subjects in seven study centers in Europe. RESULTS: In a pooled analysis incorporating stratification by center, we confirmed the previous findings that older maternal age, maternal preeclampsia, neonatal respiratory disease, and jaundice caused by blood group incompatibility are significant risk factors for type 1 diabetes, whereas being a firstborn child, having a low birth weight, or having a short birth length were protective. Cesarean section delivery and neonatal infectious diseases were not significantly associated with the risk of type 1 diabetes in this study. The strongest association was found for blood group incompatibility (AB0 and Rh factor) with an odds ratio (OR) of 2.96 (95% CI 1.88-4.65). AB0 incompatibility (OR = 3.92) was a more common and also a stronger risk factor than Rh incompatibility (OR = 1.62). The effect of AB0 blood group incompatibility was independent of treatment effects in logistical regression analysis. CONCLUSIONS: Different perinatal events are associated with an increased risk of type 1 diabetes. The effect of maternal-child blood group incompatibility is strong and indicates a true effect that must be further explored.  (+info)

Noninvasive diagnosis by Doppler ultrasonography of fetal anemia due to maternal red-cell alloimmunization. Collaborative Group for Doppler Assessment of the Blood Velocity in Anemic Fetuses. (4/234)

BACKGROUND: Invasive techniques such as amniocentesis and cordocentesis are used for diagnosis and treatment in fetuses at risk for anemia due to maternal red-cell alloimmunization. The purpose of our study was to determine the value of noninvasive measurements of the velocity of blood flow in the fetal middle cerebral artery for the diagnosis of fetal anemia. METHODS: We measured the hemoglobin concentration in blood obtained by cordocentesis and also the peak velocity of systolic blood flow in the middle cerebral artery in 111 fetuses at risk for anemia due to maternal red-cell alloimmunization. Peak systolic velocity was measured by Doppler velocimetry. To identify the fetuses with anemia, the hemoglobin values of those at risk were compared with the values in 265 normal fetuses. RESULTS: Fetal hemoglobin concentrations increased with increasing gestational age in the 265 normal fetuses. Among the 111 fetuses at risk for anemia, 41 fetuses did not have anemia; 35 had mild anemia; 4 had moderate anemia; and 31, including 12 with hydrops, had severe anemia. The sensitivity of an increased peak velocity of systolic blood flow in the middle cerebral artery for the prediction of moderate or severe anemia was 100 percent either in the presence or in the absence of hydrops (95 percent confidence interval, 86 to 100 percent for the 23 fetuses without hydrops), with a false positive rate of 12 percent. CONCLUSIONS: In fetuses without hydrops that are at risk because of maternal red-cell alloimmunization, moderate and severe anemia can be detected noninvasively by Doppler ultrasonography on the basis of an increase in the peak velocity of systolic blood flow in the middle cerebral artery.  (+info)

Anti-A isoagglutinin as a risk factor for the development of pure red cell aplasia after major ABO-incompatible allogeneic bone marrow transplantation. (5/234)

Delayed erythropoiesis and pure red cell aplasia (PRCA) have been reported after major ABO-incompatible BMT. We attempted to find risk factors for the development of PRCA in 27 patients who underwent major ABO-incompatible BMT. In all patients, the donor marrow was depleted of RBCs before infusion. In 22 patients, isoagglutinins were determined until they disappeared. In eight (29.6%) out of 27 patients, bone marrow examination following BMT showed the findings of PRCA. We analyzed various clinico-pathologic risk factors and isoagglutinin type was the only significant risk factor. Patients with anti-A isoagglutinins against donor RBC developed PRCA more frequently than patients with anti-B (8/17 vs 0/9). Median days to the disappearance of isoagglutinins tended to be longer in patients with PRCA (PRCA vsnon-PRCA, 200 vs 66 days) and in cases with anti-A isoagglutinins (anti-A vsanti-B, 160 vs 51 days). Times to disappearance of isoagglutinins correlated with times to reticulocytes over 1% and initial appearance of donor type RBC (R2 = 0.708 and 0.711). In conclusion, RBC engraftment following major ABO-incompatible BMT was dependent on the disappearance of isoagglutinins against donor RBC, and anti-A isoagglutinin was a risk factor for the development of PRCA after major ABO-incompatible allogeneic BMT. Bone Marrow Transplantation (2000) 25, 179-184.  (+info)

Relative sensitivity of direct antiglobulin test, antibody's elution and flow cytometry in the serologic diagnosis of immune hemolytic transfusion reactions. (6/234)

BACKGROUND AND OBJECTIVE: Current immunohematology practice dictates that serologic diagnosis of immune hemolytic transfusion reactions (IHTR) is based on the finding of a positive post-transfusion direct antiglobulin test (DAT). However, since DAT may fail to detect antibody-coated cells when they constitute a minor population amid a large number of non-sensitized ones, we investigated whether antibody detection in eluates or by flow cytometry is more sensitive than DAT in this context. DESIGN AND METHODS: Ten samples of red blood cells sensitized with allo- or autoantibodies were diluted in non-sensitized red blood cells to final concentrations ranging from 10% to 0.1%. DAT, antibody detection in eluates, and immunofluorescence by flow cytometry were performed on each mixture. RESULTS: DAT failed to detect sensitized cells in all but two cases in that only the 10% dilution yielded a positive DAT. Antibody detection in eluates and by flow cytometry was able to detect up to 1% sensitized cells in most cases. INTERPRETATION AND CONCLUSIONS: Antibody detection in eluates and by flow cytometry is more sensitive than DAT for detecting minor populations of IgG-coated cells. These techniques should be included in the routine investigation of suspected cases of IHTR.  (+info)

Bone marrow transplantation from alternative donors for thalassemia: HLA-phenotypically identical relative and HLA-nonidentical sibling or parent transplants. (7/234)

Twenty-nine patients with thalassemia and a median age of 6 years (range 1.1-33 years) were given a BMT from an alternative donor. Six of the 29 donors were HLA-phenotypically identical and two were mismatched relatives, 13 were mismatched siblings and eight were mismatched parents. Six patients received no antigen (relatives), 15 patients one antigen, five patients two antigen and three patients three antigen disparate grafts. Twenty-three patients were in class 2 or class 3, whereas six patients were in class 1. Thirteen patients were given BUCY, nine patients BUCY plus ALG, six patients BUCY plus TBI or TLI and one patient BUCY with prior cytoreductive-immunosuppressive treatment as conditioning. As GVHD prophylaxis four patients received MTX, 22 CsA + MTX + methylprednisolone (MP) and three patients CsA + MP. Thirteen of 29 patients (44.8%) had sustained engraftment. The probability of graft failure or rejection was 55%. There were no significant differences between antigen disparities and graft failure. The incidence of grade II-IV acute GVHD was 47.3% and chronic GVHD was 37.5%. The incidence of acute GVHD was higher in patients receiving one or two antigen disparate in the GVHD direction grafts (vs no antigen) (P EQ 0.04; odds ratio 10.8; 95% CI 1.5-115). The probability of overall and event-free survival was 65% and 21%, respectively, with median follow-up of 7.5 years (range 0.6-17 years) for surviving patients. The degree of HLA disparity between patient and donor did not have a significant effect on survival. The incidence of nonhematologic toxicity was low. Transplant-related mortality was 34%. GVHD (acute or chronic) was a major contributing cause of death (50%) followed by infections (30%). We conclude that at present, due to high graft failure and GVHD rates, BMT from alternative donors should be restricted to patients who have poor life expectancies because they cannot receive adequate conventional treatment or because of alloimmunization to minor blood antigens.  (+info)

Acceptance of an ABO-incompatible mismatched (AB(+) to O(+)) liver allograft with the use of daclizumab and mycophenolate mofetil. (8/234)

Liver allograft survival rates of 50% to 60% are reported in blood group A, group B, group O (ABO)-incompatible mismatched grafts even when aggressive immunosuppressive protocols, including plasmapheresis, OKT(3), cyclophosphamide, cyclosporine, prostaglandin E(1), and steroids, are used. A 59-year-old woman, blood type O(+), required emergency retransplantation posttransplantation day 2 because of primary nonfunction of the liver allograft. A blood type AB(+) allograft was used. Induction immunosuppressive therapy included tacrolimus, mycophenolate mofetil, OKT(3) (muromonab-CD(3)), steroids, and prostaglandin E(1). In addition, plasmapheresis was performed daily for 9 days. OKT(3) and prostaglandin E(1) were also discontinued postoperative day 9. Biopsy-proven acute cellular rejection was diagnosed postoperative day 12 and was treated with double-dose OKT(3) (10 mg) for another 6 days. On the day OKT(3) was discontinued, daclizumab, 60 mg, was administered intravenously. This dose was repeated every 2 weeks for a total of 5 doses. At 1-year follow-up, the patient is doing very well with normal liver function. We are unaware of previous reports of the use of daclizumab and mycophenolate mofetil as part of an immunosuppressive protocol aimed to induce acceptance of ABO-incompatible mismatched liver allografts. Based on our experience with this case, it seems that mycophenolate mofetil is an adequate replacement for cyclophosphamide. We also believe daclizumab provided adequate protection at a critical time. Further experience with both these drugs is required to establish their role in ABO-incompatible mismatched liver allografts.  (+info)

Blood group incompatibility refers to a situation where the blood type of a donor and a recipient are not compatible, leading to an immune response and destruction of the donated red blood cells. This is because the recipient's immune system recognizes the donor's red blood cells as foreign due to the presence of incompatible antigens on their surface.

The most common type of blood group incompatibility occurs between individuals with different ABO blood types, such as when a person with type O blood receives type A, B, or AB blood. This can lead to agglutination and hemolysis of the donated red blood cells, causing potentially life-threatening complications such as hemolytic transfusion reaction.

Another type of blood group incompatibility occurs between Rh-negative mothers and their Rh-positive fetuses. If a mother's immune system is exposed to her fetus's Rh-positive red blood cells during pregnancy or childbirth, she may develop antibodies against them. This can lead to hemolytic disease of the newborn if the mother becomes pregnant with another Rh-positive fetus in the future.

To prevent these complications, it is essential to ensure that donated blood is compatible with the recipient's blood type before transfusion and that appropriate measures are taken during pregnancy and childbirth to prevent sensitization of Rh-negative mothers to Rh-positive red blood cells.

The ABO blood-group system is a classification system used in blood transfusion medicine to determine the compatibility of donated blood with a recipient's blood. It is based on the presence or absence of two antigens, A and B, on the surface of red blood cells (RBCs), as well as the corresponding antibodies present in the plasma.

There are four main blood types in the ABO system:

1. Type A: These individuals have A antigens on their RBCs and anti-B antibodies in their plasma.
2. Type B: They have B antigens on their RBCs and anti-A antibodies in their plasma.
3. Type AB: They have both A and B antigens on their RBCs but no natural antibodies against either A or B antigens.
4. Type O: They do not have any A or B antigens on their RBCs, but they have both anti-A and anti-B antibodies in their plasma.

Transfusing blood from a donor with incompatible ABO antigens can lead to an immune response, causing the destruction of donated RBCs and potentially life-threatening complications such as acute hemolytic transfusion reaction. Therefore, it is crucial to match the ABO blood type between donors and recipients before performing a blood transfusion.

The Coombs test is a laboratory procedure used to detect the presence of antibodies on the surface of red blood cells (RBCs). It is named after the scientist, Robin Coombs, who developed the test. There are two types of Coombs tests: direct and indirect.

1. Direct Coombs Test (DCT): This test is used to detect the presence of antibodies directly attached to the surface of RBCs. It is often used to diagnose hemolytic anemia, a condition in which RBCs are destroyed prematurely, leading to anemia. A positive DCT indicates that the patient's RBCs have been coated with antibodies, which can occur due to various reasons such as autoimmune disorders, blood transfusion reactions, or drug-induced immune hemolysis.
2. Indirect Coombs Test (ICT): This test is used to detect the presence of antibodies in the patient's serum that can agglutinate (clump) foreign RBCs. It is commonly used before blood transfusions or during pregnancy to determine if the patient has antibodies against the RBCs of a potential donor or fetus, respectively. A positive ICT indicates that the patient's serum contains antibodies capable of binding to and agglutinating foreign RBCs.

In summary, the Coombs test is a crucial diagnostic tool in identifying various hemolytic disorders and ensuring safe blood transfusions by detecting the presence of harmful antibodies against RBCs.

Neonatal jaundice is a medical condition characterized by the yellowing of a newborn baby's skin and eyes due to an excess of bilirubin in the blood. Bilirubin is a yellowish substance produced by the normal breakdown of red blood cells, which are then processed by the liver and excreted through the bile. In neonatal jaundice, the liver is not yet fully developed and cannot process bilirubin quickly enough, leading to its accumulation in the body.

Neonatal jaundice typically appears within the first 2-4 days of life and can range from mild to severe. Mild cases may resolve on their own without treatment, while more severe cases may require medical intervention such as phototherapy or a blood transfusion. Risk factors for neonatal jaundice include prematurity, bruising during birth, blood type incompatibility between mother and baby, and certain genetic disorders.

It is important to monitor newborns closely for signs of jaundice and seek medical attention if concerned, as untreated neonatal jaundice can lead to serious complications such as brain damage or hearing loss.

Blood group antigens are molecular markers found on the surface of red blood cells (RBCs) and sometimes other types of cells in the body. These antigens are proteins, carbohydrates, or glycoproteins that can stimulate an immune response when foreign antigens are introduced into the body.

There are several different blood group systems, but the most well-known is the ABO system, which includes A, B, AB, and O blood groups. The antigens in this system are called ABO antigens. Individuals with type A blood have A antigens on their RBCs, those with type B blood have B antigens, those with type AB blood have both A and B antigens, and those with type O blood have neither A nor B antigens.

Another important blood group system is the Rh system, which includes the D antigen. Individuals who have this antigen are considered Rh-positive, while those who do not have it are considered Rh-negative.

Blood group antigens can cause complications during blood transfusions and pregnancy if there is a mismatch between the donor's or fetus's antigens and the recipient's antibodies. For example, if a person with type A blood receives type B blood, their anti-B antibodies will attack the foreign B antigens on the donated RBCs, causing a potentially life-threatening transfusion reaction. Similarly, if an Rh-negative woman becomes pregnant with an Rh-positive fetus, her immune system may produce anti-D antibodies that can cross the placenta and attack the fetal RBCs, leading to hemolytic disease of the newborn.

It is important for medical professionals to determine a patient's blood group before performing a transfusion or pregnancy-related procedures to avoid these complications.

The Rh-Hr blood group system is a complex system of antigens found on the surface of red blood cells (RBCs), which is separate from the more well-known ABO blood group system. The term "Rh" refers to the Rhesus monkey, as these antigens were first discovered in rhesus macaques.

The Rh system consists of several antigens, but the most important ones are the D antigen (also known as the Rh factor) and the hr/Hr antigens. The D antigen is the one that determines whether a person's blood is Rh-positive or Rh-negative. If the D antigen is present, the blood is Rh-positive; if it is absent, the blood is Rh-negative.

The hr/Hr antigens are less well known but can still cause problems in blood transfusions and pregnancy. The Hr antigen is relatively rare, found in only about 1% of the population, while the hr antigen is more common.

When a person with Rh-negative blood is exposed to Rh-positive blood (for example, through a transfusion or during pregnancy), their immune system may produce antibodies against the D antigen. This can cause problems if they later receive a transfusion with Rh-positive blood or if they become pregnant with an Rh-positive fetus.

The Rh-Hr blood group system is important in blood transfusions and obstetrics, as it can help ensure that patients receive compatible blood and prevent complications during pregnancy.
