The aim of this study was to evaluate the incidence, etiology, predictors and survival impact of early AKI in the post-allogeneic HSCT setting. Patients and methodsWe performed a retrospective single center study that included 155 allogeneic transplant procedures from June 2017 through September 2019. ResultsAKI was observed in 50 patients (32%). In multivariate analysis, age (OR 31.55, 95% CI [3.42; 290.80], p=0.002), evidence of disease at the time of transplant (OR 2.54, 95% CI [1.12; 5.75], p=0.025), cytomegalovirus reactivation (OR 5.77, 95% CI [2.43; 13.72], p<0.001) and hospital stay >35 days (OR 2.66, 95% CI [1.08; 6.52], p=0.033) were independent predictors for AKI. Increasing age (HR 1.02, 95% CI [1.00; 1.04], p=0.029), increasing length of hospital stay (HR 1.02, 95% CI [1.01; 1.03], p=0.002), matched unrelated reduced intensity conditioning HSCT (HR 1.91, 95% CI [1.10; 3.33], p=0.022), occurrence of grade III/IV acute graft-versus-host disease (HR 2.41, 95% CI [1.15; 5.03], p=0.019) and need for mechanical ventilation (HR 3.49, 95% CI [1.54; 7.92], p=0.003) predicted an inferior survival in multivariate analysis. Early AKI from any etiology was not related to worse survival. ConclusionPatients submitted to HSCT are at an increased risk for AKI, which etiology is often multifactorial. Due to AKI incidence, specialized nephrologist consultation as part of the multidisciplinary team might be of benefit. ER -
