About
Vivianna Totis is a transfusion medicine specialist whose research focuses on the immunogenetics of platelet compatibility, particularly in multi-ethnic patient populations. Her key work addresses the critical challenge of Human Platelet Antigen (HPA) alloimmunization—a serious complication in patients requiring frequent platelet transfusions. Her most cited study, conducted at a transfusion center in Northeastern Italy, systematically typed blood donors of diverse geographical origins to determine HPA allele frequencies. This research provides essential data for managing alloimmunized patients in increasingly globalized healthcare settings, where donor-recipient ethnic mismatches heighten transfusion risks. By mapping HPA distributions across populations, Totis’s work directly informs safer platelet matching protocols for refractory patients. While her citation count reflects the niche but vital nature of her field, her contributions are foundational for transfusion services adapting to demographic shifts. Her study remains a practical reference for blood banks seeking to reduce alloimmunization rates through donor pool diversification—a quiet but impactful achievement in precision transfusion medicine.
