ABSTRACT
ABSTRACT Introduction:
Allogeneic Hematopoietic Stem Cell Transplantation (allo-HSCT) patients are exposed to acute and chronic nephrotoxic events (drugs, hypotension, infections, and microangiopathy). The need for hemodialysis (HD) may be associated with high mortality rates. However, the risk factors and clinical impact of HD are poorly understood.Aim:
To analyze survival and risk factors associated with HD in allo-HSCT Patients andmethods:
single-center cohort study 185 (34 HD cases versus 151 controls) consecutive adult allo-HSCT patients from 2007-2019. We performed univariate statistical analysis, then logistic regression and competing risk regression were used to multivariate analysis. Survival was analyzed by Kaplan-Meier and Cox proportional-hazards models.Results:
The one-year HD cumulative incidence was 17.6%. Univariate analysis revealed that HD was significantly associated with male gender, age (p 0.056), haploidentical donor, grade II-IV acute GVHD, polymyxin B, amikacin, cidofovir, microangiopathy, septic shock (norepinephrine use) and steroid exposure. The median days of glycopeptides exposure (teicoplanin/vancomycin) was 16 (HD) versus 10 (no HD) (p 0.088). In multivariate analysis, we found norepinephrine (hazard ratio, HR3.3; 95% confidence interval, 95%CI1.2-8.9; p 0.024), cidofovir drug (HR11.0; 95%CI4.6 - 26.0; p < 0.001), haploidentical HSCT (HR1.94; 95%CI0.81-4.65; p 0.14) and Age (HR1.01; 95%CI 0.99-1.03; p 0.18). The HD group had higher mortality rate (HR6.68; 95% CI 4.1-10.9; p < 0.001).Conclusion:
HD was associated with decreased survival in allo-HSCT. Carefully use of nephrotoxic drugs and improving immune reconstitution could reduce severe infections (shock) and patients requiring cidofovir, which taken together may result in lower rates of HD, therefore improving survival.Palavras-chave
