BACKGROUND A new protocol for ABO-incompatible kidney transplantation has recently been introduced. We report here on the joint experience of the implementation in Stockholm and Uppsala, Sweden and Freiburg, Germany. METHODS The new protocol utilizes antigen-specific immunoadsorption to remove existing ABO-antibodies, rituximab, and intravenous immunoglobulin to prevent the rebound of antibod...
Since the cloning in 1990 of complementary DNA corresponding to messenger RNA transcribed at the blood group ABO locus, polymorphisms and phenotypegenotype correlations have been reported by several investigators. Exons 6 and 7, constituting 77% of the gene, have been analyzed previously in samples with variant phenotypes but for many subgroups the molecular basis remains unknown. This study an...
Background Multiple studies have failed to reveal an effective method for preventing the recurrence of primary sclerosing cholangitis (PSC) after liver transplantation (LTx). A national study conducted in Japan revealed several risk factors for the recurrence after living donor LTx (LDLTx); however, recipients of ABO-blood type incompatible (ABO-I) LTx were excluded from the previous analysis. ...
SUMMARY: BACKGROUND: The gene locus for the ABO blood group system encodes a glycosyltransferase. Alterations in the DNA sequence are associated with the blood groups and the expression levels of antigens on red blood cells. A number of ABO alleles have been described as the molecular basis of weak A or B antigens. PATIENTS AND METHODS: Here, we describe a novel variant B allele in a blood dono...
مقدمه: امروزه بیمارستان ها، منابع قابل توجهی را به منظور جلب همکاری چند جانبه گروه ها و بخش های مختلف بیمارستانی در قالب کمیته ها برای فراهم آوردن زمینه های بهبود عملکرد صرف می نمایند. این مطالعه با هدف مقایسه استانداردهای کمیته های بیمارستانی در دو برنامه ملی ارزشیابی و اعتباربخشی ایران انجام شد. روش پژوهش:این پژوهش از نوع مطالعات توصیفی - تطبیقی می باشد. برای گردآوری داده ها با استفاده از است...
Background: ABO incompatibility is the most common cause of immune hemolytic disease of the newborn (HDN) and in most cases is not dangerous. The present study aimed to determine the prevalence of ABO-HDN and its effects on neonatal blood parameters in a population of patients referred to some training hospitals in Iran. Materials and methods: In This cross-sectional study, All newborns (a tot...
in most of history books 4th a.h. has been introduced a sadifferent kind of islamic civilization, because of having a lot of well known person that can astonish researchers. there were a lot of people who migrated to basre and learned arabic and literature from ebne doraid. sinse knowing words is very important and it’s source other knowledges and it shows his greatpart in growing science and c...
For human embryonic stem cells (hESCs) to be used clinically, it is imperative that immune responses evoked by hESCs and their derivates after transplantation should be prevented. Human leukocyte antigens (HLA) and ABO blood group antigens are important histocompatibility factors in graft rejection. HLA matching between recipient and unrelated donors, in particular, is important in improving ou...
Introduction ABO hemolytic disease of the newborn is most common cause of neonatal jaundice; previous studies have shown a poor correlation between serologic tests and clinical course in affected infants. The aim of this study was to identify the value of direct and indirect Coombs’ immunohematological tests, to identify the incidence of hemolytic disease in newborns (ABO-HDN). Methods : This ...
CONTEXT Hemolytic transfusion reactions due to platelet transfusions containing ABO-incompatible plasma (ie, group O platelets into a non-group O patient) have been reported in the literature. However, limited data describe the extent to which transfusion services manage such platelet transfusions or the methods used to limit the risk of such reactions. OBJECTIVE To determine transfusion serv...
