BACKGROUND The deletion of three adjacent nucleotides in an exon may cause the lack of a single amino acid, while the protein sequence remains otherwise unchanged. Only one such in-frame deletion is known in the two RH genes, represented by the RHCE allele ceBP expressing a "very weak e antigen." STUDY DESIGN AND METHODS Blood donor samples were(More)
BACKGROUND The GERMS Group initiated a prospective multicenter study to assess prevalence and nature of bacterial contamination of pooled buffy-coat platelet concentrates (PPCs) and apheresis platelet concentrates (APCs) by routine screening with a bacterial culture system. STUDY DESIGN AND METHODS In nine centers overall, 52,243 platelet (PLT)(More)
BACKGROUND A fully automated single-tube assay with tubes (BD TruCOUNT, BD Biosciences) for absolute counting of residual cells in freshly prepared plasma by flow cytometry was developed (BD Plasma Count). STUDY DESIGN AND METHODS The nucleic acid dye thiazole orange stains white blood cells (WBCs). The monoclonal antibodies anti-CD41a-peridinin(More)
De novo donor-specific HLA antibodies (DSA) after renal transplantation are known to be correlated with poor graft outcome and the development of acute and chronic rejection. Currently, data for the influence of de novo DSA in patient cohorts including only living-donor renal transplantations (LDRT) are limited. A consecutive cohort of 88 LDRT was tested(More)
This presentation shows our experiences with the preoperative autologous blood donation existing since 1987, 246 patients of the cardiothoracic surgery participated in this program. The preoperative concentration of hemoglobin was above 12g/dl 76.8% of the patients despite the frequent donations, 36.5% of the participants could be transfused with their own(More)
BACKGROUND Weak D expression is caused by a large number of RHD alleles. Increasingly recommendations for D+ or D- transfusions are based on polymerase chain reaction (PCR) identification of certain RHD alleles. Possible sources of error are rare D variants that are inadvertently carrying known polymorphisms of frequent weak D types. STUDY DESIGN AND(More)
INTRODUCTION Different transfusion ratio concepts of packed red blood cells (pRBCs), fresh frozen plasma (FFP) and platelets (PLTs) have been implemented in trauma care, but the optimal ratios are still discussed. In this study the hemostatic potential of two predefined ratios was assessed by using an in vitro thrombelastometric approach. Furthermore, age(More)
One of the major tasks of histocompatibility and immunogenetics laboratories is the pretransplant determination of unacceptable antigen mismatches (UAM) in kidney transplant recipients. In this procedure, human leucocyte antigen (HLA) specificities are defined against which the patient has circulating alloantibodies that are expected to harm the(More)
OBJECTIVES To analyse which fibrinogen source may improve coagulation using an in vitro 33% dilutional coagulopathy model. BACKGROUND Uncritical volume resuscitation in the context of trauma haemorrhage contributes to the iatrogenic arm of the acute trauma-induced coagulopathy through dilution and depletion of coagulation factors, with fibrinogen reaching(More)
This study presents our preoperative autologous blood donation programme that is in use since 1987. 246 patients of cardiothoracic surgery participated in this program. 77% of all patients had preoperative concentrations of haemoglobin above 12g/dl despite frequent donations. 36.5% of patients were transfused exclusively with their own blood products.(More)
