ABO antibody titres: a multisite comparative study of equivalency and reproducibility for automated solid-phase and haemagglutination titration, and manual dilution with gel column agglutination technology.

Background: ABO antibody titres are important in many clinical decisions; however, much variability is observed in titre results. For reliable and reproducible titre results, automated ABO titration methods have been developed. In this 10-site study, we evaluated the equivalency of the automated ABO titration assays on the Galileo NEO, a fully automated blood bank analyzer (Immucor, Inc.

Impact of Covid-19 epidemic on the activities of a blood centre, transfusion support for infected patients and clinical outcomes.

Objectives: We evaluated how the Severe Acute Respiratory disease from Coronavirus 2 (SARS-CoV-2) epidemic impacted transfusion services, transfusion support required by Covid-19 patients and their clinical outcome.

Background: In Italy, the first confirmed case of SARS-CoV-2 infection was registered on 21 February 2020. As of 20 April, about 250 000 cases were registered, 1143 of which were in the province of Pescara.

Development of the Platelet Efficacy Score (PEscore) to predict the efficacy of platelet transfusion in oncohematologic patients.

Background: Despite the prophylactic use of platelet transfusion, hemorrhagic complications still represent an important cause of morbidity and mortality in patients with hematologic malignancies. Patient-related factors and characteristics of the transfused product can affect transfusion efficacy.

Study Design And Methods: The aim of this study was to develop and validate the Platelet Efficacy Score (PEscore), based on patient and product characteristics, to predict the likelihood of a satisfactory platelet transfusion (absolute increment ≥10.

Survey of current practice for monitoring and management of platelet refractoriness in Italy.

Platelet transfusion failure is a common phenomenon affecting from 7% to 34% of haematology-oncology patients. Monitoring the efficacy of platelet transfusion through the evaluation of a post-transfusion platelet count and clinical response represent an important guide for subsequent transfusions and for the detection of refractoriness. The aim of this survey was to investigate physicians' attitudes and practices regarding the monitoring of platelet response and the management of platelet refractoriness.

Bacterial contamination of platelets and septic transfusions: review of the literature and discussion on recent patents about biofilm treatment.

In spite of the improvements in transfusion safety occurred in the last decades, platelet septic transfusions still represent a cause for concern. Microbial screening of blood products cannot ensure transfusion sterility, so that pathogen inactivation methods and a timely management of infectious events actually play the most relevant role. Biofilm production has been associated to several human illnesses; also, it promotes bacterial adherence to platelet bags and colonization of recipient's catheter after transfusion.
