ABSTRACT
Objective To evaluate the effect of pretransplant iron overload on the clinical efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with severe aplastic anemia (SAA). Methods Clinical data of 80 SAA recipients who underwent allo-HSCT for the first time were retrospectively analyzed. According to the incidence of iron overload, all recipients were divided into the iron overload group (n=20) and non-iron overload group (n=60). The engraftment rate, incidence of postoperative complications and clinical prognosis of the recipients afterallo-HSCT were statistically compared between two groups. The influencing factors of 2-year overall survival (OS) and 180 d transplantation related mortality (TRM) were analyzed by Cox proportional hazards regression model. Results The engraftment rate of neutrophils in the non-iron overload group was 98% (59/60), significantly higher than 75% (15/20) in the iron overload group (P < 0.05). The engraftment rate of platelet in the non-iron overload group was 90% (54/60), significantly higher than 65% (13/20) in the iron overload group (P < 0.05). The incidence rate of bloodstream infection in the non-iron overload group was 23% (14/60), remarkably lower than 40% (8/20) in the iron overload group (P < 0.05). The 180 d TRM of the recipients in the non-iron overload group was 17%, significantly lower than 45% in the iron overload group (P < 0.05). The 1- and 2-year OS of the recipients in the non-iron overload group were 82% and 80%, significantly higher than 50% and 44% in the iron overload group (both P < 0.05). Iron overload or not was an independent risk factor of the OS and TRM of the recipients (both P < 0.05). Conclusions Iron overload can affect the OS and TRM of SAA patients after allo-HSCT.
