Background

Ferric pyrophosphate citrate injection (FPC-IV) is an iron replacement product to maintain hemoglobin by intravenous infusion (IV) over 3 to 4 hours. Some hemodialysis (HD) centers cannot use HD system syringe pumps for drug administration. We investigated the use of a spring-driven syringe pump to infuse FPC IV into the pre-or post dialyzer blood lines.

Methods

An open-label, study was conducted in 12 HD patients at 6 treatments. FPC-IV (6.75mg Fe/4.5 mL) was drawn up into 20 mL syringes. The syringe was attached to a flow-restrictor tubing 2 mL/hr (nominal rate) and then attached to the the pre-Dialyzer blood line port or to the venous drip chamber. The syringe was placed in the chamber of the FreedomEdge® Pump (FP) and the pump activated. Blood for serum iron (sFe) and transferrin saturation (TSAT) was collected pre-hemodialysis and immediately post infusion.

Results

FP Delivery of FPC took an average of 134 ± 31.7 minutes (Range 71 to 195 min). The mean increment in sFe pre- to post infusion was 202 ± 73.7 µg/dL. The pump set up, including loading the syringe, took an average of 109 ± 42.7 sec (Range: 48 to 251 sec.). The incremental sFe in this study is compared to the dialysate and IV FPC infusions over 3 hours in Figure 1. The sFe was rapidly cleared with no increase in pre-dialysis sFe. FPC-IV was well tolerated with no reported adverse events.

Conclusion

The results of this study demonstrate that FPC-IV can be safely administered as a continuous infusion using a spring-driven pump (FP) over 71 to 195 minutes. The increment in sFe is slightly greater than the 3 or 4-hour FPC infusions due to the shorter administration time. A spring-driven infusion pump to administer FPC IV is well-tolerated and a suitable alternative to use of the Hemodialysis machine syringe pump.
