Hemolytic disease of the newborn due to ABO incompatibility was first observed by Halbrecht in 1944. This entity has a spectrum ranging from minimal hemolysis requiring no therapy, as is the case in most instances, to severe hemolytic disease requiring aggressive management including exchange transfusion in a small percentage of cases. An extreme degree of hemolytic disease of the newborn due t...

SANDLER (1970) suggested that mutation, abnormal oocyte (abo:2-38), may influence the function of the ribosomal RNA cistrons. We have examined the abo mutation and its interaction with the ribosomal D N A of Drosophila melanogaster. We observed that the expression of the abo phenotype is unstable under the appropriate conditions, a behavior which paralleled changes in the phenotypic expression ...

BACKGROUND Living-kidney transplantation is increasing because of the scarcity of kidneys from deceased donors and the increasing numbers of patients on waiting lists for a kidney transplant. Living-kidney transplantation is now associated with increased long-term patient- and allograft-survival rates. OBJECTIVES The purpose of this retrospective study was to identify, in a cohort of 44 ABO-i...

BACKGROUND AND AIMS ABO encodes a glycosyltranferase which determines the major human histo-blood group. The FUT2 fucosyltransferase allows expression of ABO antigens on the gastrointestinal mucosa and in bodily secretions (secretor phenotype). A nonsense allele in FUT2 represents a susceptibility variant for Crohn's disease, and both the secretor and ABO blood group status affect the compositi...

BACKGROUND & OBJECTIVES Literature reports several studies on ABO groups and malaria but a study with an adequate sample size and controls is not available. ABO groups are genetically controlled, hence, large sample size and comparison with population frequency is essential. To determine whether malaria infection with variable severity has correlation with ABO groups. STUDY DESIGN & METHODS B...

OBJECTIVE To analyze the frequency of and odds for and against HIV infection based on ABO blood type in a large sample of blood donors. BACKGROUND Coevolution between pathogens and hosts may explain the ABO system of polymorphisms. HIV-infected cells add ABO(H) blood group antigens to the viral envelope. Naturally occurring antibodies against ABO(H) antigens that are present in normal human s...

The independent genomic inheritance of the human leukocyte antigen (HLA) and the ABO-blood group system allows for HLA-matched hematopoietic progenitor cell transplantation (HCT) to occur in donors who are not matched for ABO blood groups. In fact, nearly one-half of all HCT will involve recipient-donor ABO incompatibility. This places the recipient at increased risk for acute and delayed hemol...

INTRODUCTION ABO blood group compatibility between donors and recipients of heart transplants is required to reduce the risk of hyperacute rejection. Ideally, ABO-identical cardiac grafts should be used but transplantating using ABO compatible types allows reduced waiting times among recipients with rarer types without a significant increase in hyperacute rejection. However, previous reports ha...

To elucidate clinical trial efficacy, safety, and dosing practices of AbobotulinumtoxinA (ABO) treatment in adult patients with lower limb spasticity.A systematic literature review was performed to identify randomized controlled trials of ABO in the treatment of adult lower limb spasticity.Of the 295 records identified, 6 primary publications evaluated ABO for the management of lower limb spast...

Cell surface ABO(H) antigenicity of superficial bladder tumours was assessed by the indirect immunoperoxidase test in 49 patients. Good correlation was obtained between surface antigenicity of tumours and the results of urine cytology. Malignant cells were detected cytologically in 22(56%) of cases with ABO(H) antigen negative tumours which are known to behave more aggressively than ABO(H) anti...
