These features are suggestive of iron overload. Hemodialysis patients with transfusional iron overload may be treated with weekly intravenous (IV) deferoxamine mesylate during the dialysis treatment. This usually results in significant improvements in liver enzymes. At concentrations greater than 500 mug/dL (90 mumol/L) coma or the combination of leukocytosis and an increased anion gap are commonly observed in iron posioning. Sole reliance on observations of vomiting, diarrhea, leukocytosis and hyperglycemia may not be useful as screening tests to detect patients with iron poisoning. The absence of all these signs or symptoms is likely to be associated with serum concentrations less than 500 mug/dL
