Background

The optimal dosing strategy for intravenous iron (IV) in hemodialysis (HD) patients with iron deficiency anemia remains uncertain. While high-dose IV iron is commonly used, concerns exist regarding its potential risks. This systematic review and meta-analysis aims to assess the efficacy and safety of high-dose IV iron in this population.

Methods

PubMed, Embase and Cochrane databases were searched for randomized controlled trials (RCTs) comparing high-dose with low-dose IV iron or no iron in HD patients with iron deficiency anemia. Risk ratios (RR) and mean differences (MD) with 95% confidence intervals (CI) were pooled across studies. Heterogeneity was assessed using I2 statistics.

Results

This analysis included five RCTs involving 2,614 patients, of whom 1,326 (50.7%) received high-dose IV iron. Mean follow-up ranged from 1.5 to 25.2 months. There was no significant difference between groups in the change from baseline in hemoglobin (MD 0.15 g/dL; 95% CI –0.26 to 0.57; p=0.47) or ferritin levels (SMD 0.98; 95% CI 0.71 to 1.26; p<0.001). In contrast, transferrin saturation was significantly increased in the high-dose IV iron group compared with control (MD 5.02 %; 95% CI 3.17 to 6.87; p<0.001). No statistically significant differences were observed between groups for cardiac adverse events (p=0.064), cardiovascular mortality (p=0.440), vascular disorders (p=0.487), or infections (p=0.948).

Conclusion

High-dose IV iron demonstrated a safety profile comparable to that of low-dose or no IV iron and was associated with significant increases in transferrin saturation, despite no improvements in hemoglobin or ferritin levels.
