Preconditioning Modified-Easix as a Predictor of Prognosis in Allogeneic Hematopoietic Stem Cell Transplant Recipients

AbstractAllogeneic hematopoietic stem cell transplantation (alloHCT) is associated with severe complications, most of which share a common physiopathological background characterized by endothelial dysfunction. A novel risk assessment model, endothelial activation and stress index (EASIX), has been introduced as a predictor of endothelial activation. This retrospective study was performed to evaluate the predictive impact of EASIX/modified-EASIX (mEASIX) on transplant outcome. Medical records of 398 alloHCT recipients [median age: 43(17 –71) years; M/F: 243/155] were examined. EASIX/mEASIX were calculated at specific time points before and after transplantation. EASIX/mEASIX were significantly associated with transplant complications including engraftment syndrome, sinusoidal obstruction syndrome, febrile neutropenia and transpla nt associated thrombotic microangiopathy. The probability of overall survival was significantly higher in low-preconditioning mEASIX (day -7) group (37% vs 25.2%;p = 0.008; HR: 2.057; 95% CI: 1.208–3.504). The probabilities of day30 mortality (2.9% vs 19.4%;p = 0.017; HR: 7.028; 95% CI: 1.418–34.836), day100 mortality (9% vs 33%;p = 0.004; HR: 4.469; 95% CI: 1.619–12.336) and non relapse mortality (44.8% vs 61.4%;p = 0.005; HR: 2.551; 95% CI: 1.318–4.941) were lower in low-preconditioning mEASIX (day -7) group. This retrospective cohort analysis demonstrates the significant impact of EASIX/mEASIX on transplant complications ...
