Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is the best curative treatment modality for many malignant hematologic disorders. In the absence of a matched related donor, matched unrelated donors (MUDs) and haploidentical donors are the most important stem cell sources. In this registry-based retrospective study, we compared the outcomes of allo-HSCTs from 10/10 MUDs with antithymocyte globulin (ATG)-based regimens (n = 7050) vs haploidentical transplants (Haplo-Tx) using posttransplant cyclophosphamide (PT-CY Haplo; n = 487) in adult patients with hematologic malignancies between 2010 and 2020.

Objectives: This study aimed to assess the validity of external quality assessment (EQA) laboratory results across various cultural and environmental contexts and to identify potential improvement areas.

Methods: The International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) Task Force on Global Laboratory Quality (TF-GLQ) conducted a 2-year study (2022 and 2023) in which EQA materials, related software and online training was provided by a commercial vendor to 100 laboratories in ten IFCC member society countries. The results were analysed on a monthly basis by the TF-GLQ, to show the number of submissions per country, tests per lab, acceptability rates, random failures and to get a measure of which analytes performed poorly.

Article Synopsis
  • MICA polymorphisms are linked to higher rates of acute GvHD and poor outcomes in patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT), with MICB's role still being unclear.
  • Researchers analyzed a large cohort for MICB polymorphisms, assessing how MICB matching affects outcomes after unrelated HSCT, finding that 69.2% were 10/10 HLA matched.
  • In the 9/10 HLA matched group, MICB mismatches led to worse disease-free survival and relapse-free survival, while MICA mismatches did not significantly impact outcomes, suggesting MICB typing might aid in donor selection among 9/10 matched donors.
