Blood transfusions and adverse acute events: a retrospective study from 214 transfusion-dependent pediatric patients comparing transfused blood components by apheresis or by whole blood.

Introduction: Blood transfusion is a lifesaving procedure for patients affected by hematological diseases or hemorrhage risk.

Aim: This retrospective study was aimed to evaluate clinical safety of pediatric transfusions by comparing the frequency of adverse events caused by apheretic blood components vs whole blood.

Methods: From 2011 to 2015, 214 patients (blood malignancy patients, n = 144 and thalassemic patients, n = 70) received 12 531 units of blood components.

Erythrocyte genotyping for transfusion-dependent patients at the Azienda Universitaria Policlinico of Naples.

Background And Objectives: Although minor erythrocyte antigens are not considered clinically significant in sporadic transfusions, they may be relevant for multi-transfusion patients. When serological assay is not conceivable, molecular genotyping allows predicting the red blood cell phenotype, extending the typing until minor blood groups. The aim of this study was to evaluate the utility of blood group genotyping and compare the molecular typing of erythrocyte antigens with the established serological methods.
