- Abstract: BACKGROUND:Allogeneic hematopoietic stem cell transplantation is an effective and even the only way to cure various hematological diseases,but the short-term mortality rate is relatively high after transplantation. OBJECTIVE:To investigate the risk factors affecting the overall survival of patients with hematological diseases in the short term(within 100 days)after allogeneic hematopoietic stem cell transplantation,so as to reduce mortality and effectively prevent related risks in the short term(within 100 days)after allogeneic hematopoietic stem cell transplantation. METHODS:Clinical data of 585 patients with hematological diseases who underwent allogeneic hematopoietic stem cell transplantation at the Hematopoietic Stem Cell Transplantation Center of First Affiliated Hospital of Zhengzhou University from January 1,2018 to June 30,2021 were retrospectively analyzed.The risk factors that affected overall survival within 100 days after allogeneic hematopoietic stem cell transplantation were explored. RESULTS AND CONCLUSION:A total of 585 patients with hematologic diseases underwent allogeneic hematopoietic stem cell transplantation.92 patients died within 100 days after transplantation,with a mortality rate of 15.7%(92/585).The median age of death cases was 26.5 years old(1-56 years),and the median survival time of death cases was 48 days(0-97 days).Univariate analysis exhibited that age≥14 years old,acute graft-versus-host disease,grade IV acute graft-versus-host disease,bacterial bloodstream infection,as well as carbapenem-resistant organism bloodstream infection,were risk factors for overall survival within 100 days after allogeneic hematopoietic stem cell transplantation(P<0.05).Multivariate regression analysis showed that age≥14 years old,grades Ⅲ-Ⅳ acute graft-versus-host disease,bacterial bloodstream infection,and carbapenem-resistant organism bloodstream infections were independent risk factors for overall survival(within 100 days)in patients after allogeneic hematopoietic stem cell transplantation.Hazard ratios were 1.77(95%CI 1.047-2.991),7.926(95%CI 3.763-16.695),2.039(95%CI 1.117-3.722),and 3.389(95%CI 1.563-7.347),respectively.In conclusion,all-cause mortality rate after allogeneic hematopoietic stem cell transplantation is relatively high in the short term.A timely diagnosis and effective treatment of bacterial bloodstream infection and acute graft-versus-host disease are essential to improving allogeneic hematopoietic stem cell transplantation outcomes.
