The relative decrease in factor D correlates with the relative increase of soluble C5b-9 by intravenous iron in hemodialysis patients. (A) Plasma levels of factor D were determined in 32 hemodialysis (HD) patients during two consecutive dialysis sessions, one with intravenous iron (Iron), and one without (No iron). During each dialysis session, factor D levels were determined at baseline and after 4 h. Data are presented as mean and SEM. (B) The correlation between the relative change of sC5b-9 and factor D between the two HD sessions. Correlations were evaluated using the Spearman rank correlation coefficient and paired sample t-test was used to compare values before and after iron infusion. P < 0.05 were considered to be statistically significant (**P < 0.01).
