Newborn Screening for Hurler Syndrome Facilitates Early Transplant and Good Outcomes.

Background: Hematopoietic cell transplantation (HCT) is the standard of care treatment for children with Hurler syndrome (HS). This study describes the impact of newborn screening (NBS) on HCT outcomes for these patients.

Methods: Retrospective study of HS patients diagnosed through NBS and referred to Duke from 2017 to 2023.

In utero human cytomegalovirus infection expands NK-like FcγRIII+CD8+ T cells that mediate Fc antibody functions.

Human cytomegalovirus (HCMV) profoundly impacts host T and NK cells across the lifespan, yet how this common congenital infection modulates developing fetal immune cell compartments remains underexplored. Using cord blood from neonates with and without congenital HCMV (cCMV) infection, we identify an expansion of Fcγ receptor III-expressing (FcγRIII-expressing) CD8+ T cells following HCMV exposure in utero. Most FcγRIII+CD8+ T cells express the canonical αβ T cell receptor (TCR), but a proportion express noncanonical γδ TCR.

Mitigation of supply chain challenges in cell therapy manufacturing: perspectives from the cord blood alliance.

Cellular therapies rely on highly specialized supply chains that often depend on single source providers. Public cord blood banks (CBB) manufacturing the first cell therapy to be highly regulated by the FDA and related international agencies are a prime example of being subject to this phenomenon. In addition to banking unrelated donor cord blood units for transplantation, CBBs also source and characterize starting materials for supply to allogeneic cell therapy developers that often employ customized technologies offered by just a small number of manufacturers.

Impact of FDA's HCT/P ZIKV Recommendations on Cord Blood Unit Eligibility and Utilization in a Large Public Cord Blood Bank.

Background: Cord blood units (CBUs) that are ineligible for licensure due to incomplete compliance with FDA recommendations may be used for hematopoietic stem cell transplantation under urgent medical need and an Investigational Drug Application. The largest reason for CBU donor ineligibility is Zika virus (ZIKV) risk. The study's objective was to analyze the impact of current FDA recommendations for ZIKA risk on a large public cord blood bank and propose updated recommendations.
