Abstract
BACKGROUND:
The optimal level of serum ferritin (s-ft) for anemia control and good survival in hemodialysis (HD) patients remains unclear. A 10-year survey was performed to clarify the appropriate quantities of s-ft and investigate the relationships among s-ft,
transferrin saturation (TSAT), and mortality in HD patients.
METHODS:
HD outpatients (n = 125) treated with erythropoiesis-stimulating agents (ESA) were followed for 10 years. The ESA and low-dose iron supplement dosages were adjusted to maintain the hemoglobin (Hb) at 10-11 g/dl, according to Japanese guidelines. The
Kaplan-Meier method, log-rank tests, and the Cox proportional hazards model were used for performing the statistical analyses. The interactions among the Hb, s-ft, and TSAT were analyzed using a multiple linear regression model. Patients with TSAT ≥20%
were classified according to the s-ft cutoff values: group 1 (s-ft <30 ng/ml); group 2 (s-ft 30-80 ng/ml); group 3 (s-ft >80 ng/ml); TSAT <20% was a predictor of poor outcome.
RESULTS:
The survival rate in group 2 was significantly higher than that in other groups (p = 0.013), and the Cox proportional hazards model analysis showed a good effect of low levels of s-ft on patients' survival. The multiple linear regression model showed a
strong effect of s-ft on the Hb (log [s-ft], β-coefficient -0.45: 95% confidence interval -0.65 to -0.26, p < 0.001).
CONCLUSION:
This study revealed that low levels of s-ft have a beneficial effect on the outcome of HD patients receiving ESA. Thus, the optimal s-ft level might be lower than that established previously for these patients.
