A best evidence topic (BET) in cardiac surgery was written according to a structured protocol. The question addressed was whether ABO-incompatible (ABO-I) heart transplant recipients have a similar survival rate as an ABO-compatible (ABO-C) transplant in the pediatric population <1 year of age. Altogether more than 112 papers were found using the reported search, of which 10 represented the bes...

In this study we analyzed the complete genomic sequences, except intron 1, and 2 regulatory regions of 6 common (ABO*A101, ABO*A201, ABO*B101, ABO*O01, ABO*O02, and ABO*O03) and 18 rare ABO alleles, 3 of which were new. This was done by phylogenetic analysis and correlating sequence data with the ABO phenotypes. The study revealed multiple polymorphisms in noncoding regions. The intron-based ph...

AIM To evaluate the differences in outcomes between ABO-incompatible (ABO-I) liver transplantation (LT) and ABO-compatible (ABO-C) LT. METHODS A systematic review and meta-analysis were performed by searching eligible articles published before No-vember 28, 2016 on MEDLINE (PubMed), EMBASE, and Cochrane databases. The primary endpoints were graft survival, patient survival, and ABO-I-related ...

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...

The ABO blood group is the most important blood group system in transfusion medicine and organ transplantation. To date, more than 160 ABO alleles have been identified by molecular investigation. Almost all ABO genotyping studies have been performed in blood donors and families and for investigation of ABO subgroups detected serologically. The aim of the present study was to perform ABO genotyp...

BACKGROUND: The ABO blood groups result from DNA sequence variations, predominantly single nucleotide and insertion/deletion polymorphisms (SNPs and indels), in the ABO gene encoding a glycosyltransferase. The ABO blood groups A(1), A(2), B and O predominantly result from the wild type allele A1 and the major gene variants that are characterized by four diallelic markers (261G>del, 802G>A, 803G...

ABO is the most clinically important blood group system in transfusion and transplantation medicine. The popular ABO genotyping methods, such as the sequencing of exons 6 and 7 and sequence-specific primer (SSP)-PCR, often lead to ambiguous typing results. Long PCR-sequencing method was designed to analyze two regulatory regions (promoter and CBF/NF-Y enhancer regions) and all genomic sequences...

BACKGROUND Amerindian admixture is an important parameter to consider in epidemiological studies in American countries, to make a proper selection of cases and controls. AIM To compare Amerindian admixture estimates obtained using ABO*A and ABO*O blood group alleles and ancestral identity markers (AIMs) in the mixed Chilean population. SUBJECTS AND METHODS Amerindian admixture rates were de...

ABO histo-blood group antigens have been postulated to modify pathogen spread through the action of natural antibodies and complement. The antigens are generated by a polymorphic glycosyltransferase encoded by 2 dominant active and a recessive inactive allele. In this study we investigated whether ABO sugars are incorporated into the envelope of HIV-1 virions. HIV vectors derived from cells exp...
