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.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
