ABSTRACT
Ukraine’s healthcare system has shown remarkable resilience in continuing newborn screening (NBS), beyond the challenges of war. Amid the conflict, a Ukrainian newborn screened positive for an extremely rare severe combined immunodeficiency (SCID)-purine nucleoside phosphorylase (PNP) deficiency. Ukraine successfully carried out NBS on a neonatal dried blood spot (DBS) by real-time PCR, which showed remarkably reduced T-cell receptor and kappa-deleting recombination excision circles (TREC/KREC). Retesting was delayed due to communication difficulties with the family. Whole exome sequencing on a new DBS confirmed the diagnosis. The newborn was a candidate for allogeneic hematopoietic stem cell transplantation (HSCT), the only curative treatment. HSCT is a complex procedure still ongoing in Ukraine despite the conflict. However, due to the psychosocial strain, the family sought medical support in Germany, where HSCT was performed successfully at 6 months. As part of a collaborative initiative with Italy, PNP biomarkers were quantified on the same DBSs using tandem mass spectrometry, according to the protocols established for SCID NBS in Tuscany, serving as a proof of concept of its diagnostic performance. This case highlights the importance of sustaining preventive and life-saving healthcare services, and reflects the key role of international partnerships in upholding the right to healthcare in times of crisis.
