Iron deficiency is common and when oral treatment is not sufficient intravenous application is indicated. Hypersensitivity to intravenous iron nanomedicines is rare but does occur and little is known about the underlying mechanism but complement activation has been suggested. This is a purely exploratory study as it is not yet known whether in vitro complement activation can be stimulated by titration with iron preparations. These data will provide first empirical evidence of whether and to what extent complement activation occurs in this population.

Complement activation
The primary outcome, complement activation, will be measured by the respective concentrations of the complement compounds sC5b9, C4d, C3a and C5a (ng/ml), and CP, LP and AP (%) 30 minutes after titration of two concentrations (100 ng/ml and 500 ng/ml) of Ferinject and Venofer into serum probes. That is for each subject, four serum probes will be analysed (100 ng/ml Ferinject, 500 ng/ml Ferinject, 100 ng/ml Venofer and 500 ng/ml Venofer).
