Pretransplant serum ferritin level may be a?predictive marker for outcomes in patients having undergone allogeneic hematopoietic stem cell transplantation.

摘要

Iron overload increases the risk of infections, veno-occlusive disease and hepatic dysfunction in post-transplant period. Our objective was to investigate the association of pre-transplant ferritin levels with complications and survival after allogeneic hematopoietic stem cell transplantation (alloHSCT).We retrospectively analysed 84 patients' data who had undergone allogeneic HSCT into two groups: patients with a?serum ferritin level≥1000ng/ml, and patients with <1000?ng/ml at the time of HSCT.Cox-regression analysis showed that pre-transplant serum ferritin levels were significantly higher in patients who had at least one infectious event compared with those who had no any infectious event in the post-transplant 100 days (p<0.023). Overall survival (OS) and disease-free survival (DFS) rates were significantly higher in patients with a?time-to-tx interval 12 months (p=0.002 and p=0.008 respectively). A?higher risk of death was observed in high-ferritin group (hazard ratio=2.27, CI:1.01-5.09, p=0.023 for OS and hazard ratio=2.49, CI:1.12-5.53 p=0.039 for DFS). No significant effect on OS and DFS among groups was observed for variables conditioning regimen, gender and diagnosis. Acute GVHD was more common in patients with a?ferritin level ≥1000 ng /mL, but this was not statistically significant (p>0.05). There was no statistical significance in both groups (ferritin≥1000ng /mL and ferritin0.05). Platelet and neutrophil engaftment day was not found statistically significant compared with both groups (p=0.273 and p=0.882, respectively).Pre-transplant ferritin levels may predict poor outcomes in patients who had undergone allogeneic hematopoietic stem cell transplantation.
