A real-life evaluation of two platelet cross-matching programmes for the treatment of patients refractory to platelet transfusions.

Background And Objectives: Strategies for overcoming alloimmune refractoriness to random donor platelets are based on the use of compatible platelets selected from large panels of HLA-typed donors or cross-matching (XM). The aim of this study was to review the effectiveness of a platelet XM programme for treating refractory haematological patients at Milan's Policlinico Hospital (PHM) 2002-2014 and Spedali Civili in Brescia (SCB) 2013-2016.

Materials And Methods: A commercially available solid-phase antibody detection system was used for platelet antibody detection and XM.

Strategies for the transfusion of subjects with complex red cell immunisation: the Bank of rare blood donors of the Region of Lombardy.

Introduction: Selecting units of rare blood for transfusion to patients with complex immunisation is one of the most critical processes of a Transfusion Centre. In January 2005 the 'Rare Blood Components Bank - Reference Centre of the Region of Lombardy' w as established with the following goals: 1) identifying regional rare blood donors; 2) creating a regional registry of rare donors; 3) organising a regional bank of liquid and frozen rare blood units; 4) setting up a regional Immunohaematology Reference Laboratory (IRL) to type donors and resolve complex cases.

Methods: The key elements in establishing the Bank were periodic meetings organised by the directors and representatives of the regional Departments of Transfusion Medicine and Haematology (DTMH) and the institution of three working groups (informatics, regulations, finance).
