NCT04888286

Brief Summary

Retrospective observational multicentric, spontaneous non-interventional non-pharmacological Italian study. The primary objective is analysis of Anti-HLA antibodies and DSAs searching and monitoring activities in haematological adult and paediatric patients undergoing allo-HSCT from January 2014 to June 2017. This study will evaluate approximately 1000 subjects (with competitive enrolment) from GITMO investigational centers.

Outcome Measures

Primary Outcomes (3)

  • Analysis of the monitoring practice of DSAs

    The variables that will be collected are: Type of transplant in which the search for DSAs is carried out, Laboratory methods used, Positivity cut-off used, Donor selection criteria if DSAs present, Desensitization protocol employed

    6 months from allogeneic hematopoietic stem cell transplantation

  • Role of DSAs on neutrophils and platelets engraftment

    Time to reach an absolute neutrophil count \> 0.5 109/L from day of HSCT. Neutrophil recovery end-point will be defined as the first of 3 consecutive days with an absolute neutrophil count \> 0.5 x109/L. Time engraftment of platelet count will be defined as PTLS \>20.9 x 109/L without transfusion requirements for at least 5 days.

    28 days from allogeneic hematopoietic stem cell transplantation

  • Graft failure

    graft failure is defined as peripheral blood ANC \< 0.5 × 109/L by after allogeneic hematopoietic stem cell transplantation without evidence of relapse

    28 days from allogeneic hematopoietic stem cell transplantation

Study Arms (1)

patients who underwent mismatched allogeneic transplantation

Pediatric and adult patients who underwent mismatched allogeneic transplantation, from January 2014 to June 2017.
