- Abstract
Iron overload is considered a risk factor for mortality in patients with hematopoietic malignancies. Hepcidin is a key regulator of systemic iron balance. We previously reported dynamic changes of serum hepcidin-25 levels in patients with hematologic malignancies after allogeneic hematopoietic stem cell transplantation (allo-HSCT). In this study, we retrospectively analyzed the association of pretransplant hepcidin-25 levels with overall survival (OS), engraftment, and other clinical outcomes of allo-HSCT in patients with hematologic malignancies. A total of 166 patients were divided into two groups depending on their pretransplant serum hepcidin-25 levels; their median age was 49.5 years, and the median follow-up time was 46.8 months. At 3 years, the patients in the high-hepcidin group had a significantly lower OS than those in the low-hepcidin group (49.2 vs. 69.0%, respectively; P = 0.006). Multivariate analysis revealed that pretransplant serum hepcidin-25 level, sex, and disease status were independently associated with OS. The incidence of platelet engraftment was significantly lower in the high-hepcidin group than in the low-hepcidin group, whereas no significant differences were observed in neutrophil and reticulocyte engraftments between these groups. Hence, pretransplant serum hepcidin levels can be a marker for predicting delayed platelet recovery after allo-HSCT.
