In the century since the discovery of the ABO blood groups, numerous associations between ABO groups and disease have been noted. However, the selection pressures defining the ABO distributions remain uncertain. We review published information on Plasmodium falciparum infection and ABO blood groups. DNA sequence information dates the emergence and development of the group O allele to a period o...
ABO incompatibility is commonly observed in stem cell transplantation and its impact in this setting has been extensively investigated. HLA-mismatched unrelated donors (MMURD) are often used as an alternative stem cell source but are associated with increased transplant related complications. Whether ABO incompatibility affects outcome in MMURD transplantation for acute myeloid leukemia (AML) p...
SUMMARY Many modern therapies depend on platelet (PLT) transfusion support. PLTs have a 4- to 7-day shelf life and are frequently in short supply. In order to optimize the inventory PLTs are often transfused to adults without regard for ABO compatibility. Hemolytic reactions are infrequent despite the presence of 'high titer' anti-A and anti-B antibodies in some of the units. Despite the low ri...
Platelet concentrates from ABO-identical donors are the components of choice for transfusions. Since platelet inventories are generally insufficient and because there is usually a higher frequency of group O donors, perfect matches are not always possible and therefore ABO-incompatible platelet transfusions are an accepted practice when ABO-identical platelets are unavailable.1 However, an acut...
Pre-transfusion testing is performed to ensure the normal survival of transfused red blood cell products i.e. to prevent hemolytic transfusion reaction via immune-mediated mechanism [1]. The serological part of pre-transfusion testing includes; ABO group and Rh (D) type, antibody screening and crossmatching [2]. Antibody screening is included to detect unexpected antibody and was first introduc...
We aimed to determine the role of exchange transfusion related complications, treatment, and etiology as well as subgroup incompatibility in patients subject to ET (exchange transfusion) due to newborn jaundice. 82 patients hospitalized due to newborn jaundice and exposed to exchange transfusion between August 2007 and August 2011 were retrospectively studied. Before ET mean total serum bilirub...
ABO blood group, except its direct clinical implications for transfusion and organ transplantation, is generally accepted as an effect factor for coronary heart disease, but the associations between ABO blood group and congenital heart disease (CHD) are not coherent by previous reports. In this study, we evaluated the the potential relationship between ABO blood group and CHD risk. In 39,042 co...
OBJECTIVE To assess the efficacy of managing pregnancies complicated by anti-Kell isoimmunization using the methods developed for evaluating anti-Rh-D isoimmunization. METHODS We reviewed 156 anti-Kell-positive pregnancies seen from 1959 to 1995, which were managed with serial maternal titers, amniotic fluid deltaOD450 determination, and funipuncture. Data on maternal titers, paternal phenoty...
