Abstract

Background/Aims: Intravenous iron infusion is the accepted way of supplementation of that compound in uremic patients. The aim of the study was to evaluate whether this treatment affects intraperitoneal homeostasis in patients on peritoneal dialysis. Methods: Blood and peritoneal dialysate samples were collected from 10 patients treated with continuous ambulatory peritoneal dialysis who were given 100 mg iron sucrose (IS) intravenously. Systemic and peritoneal permeability as well as transperitoneal transport were studied. The effect of spent dialysate was tested in vitro on human peritoneal mesothelial cells (MCs). Results: Dialysate total iron was increased (+19%, p < 0.01) during intravenous infusion of IS. Immediately after infusion the concentration of 8-OHdG was increased in plasma (+10%, p < 0.01) and in dialysate (+5%, p < 0.05). IS infusion caused a transient decrease in peritoneal permeability to protein (-42%, p < 0.05) and glucose (-30%, p < 0.01) and a reduction in dialysate cell count (-58%, p < 0.05). During the exchange dialysate hyaluronan was increased by 27% (p < 0.01). Spent dialysate, tested ex vivo on cultured MC, induced oxidative stress (+39%, p < 0.01), slowed their proliferation (-20%, p < 0.01), and stimulated MCP-1 synthesis (+46%, p < 0.01). Iron content in MCs exposed to dialysate obtained after IS infusion was increased by 32% (p < 0.01). Conclusion: Intravenous infusion of IS causes oxidative stress and inflammation within peritoneal MCs which may impair viability of the peritoneum.
