Hepatic iron content and the risk of Staphylococcus aureus bacteremia
in liver transplant recipients. [Journal Article]
Prog Transplant 2007 Dec; 17(4):332-6.

Iron is a critical nutrient source and contributes to staphylococcal
pathogenesis. We assessed the role of hepatic explant iron overload as
a risk factor for Staphylococcus aureus bacteremia in liver transplant
recipients. Seven of 13 cases with S aureus bacteremia (53.8%) had
hepatic explant iron concentrations that exceeded normal limits (grade

and hepatocellular carcinoma as underlying liver disease (P = .04),
but not hepatic explant iron concentration, correlated with a higher
risk of S aureus bacteremia after transplantation. However,
noncarriers (patients without S aureus nasal carriage) who developed S
aureus bacteremia were more likely to have high hepatic iron content;
4 of 7 (57%) noncarriers with high-grade iron content developed S
aureus bacteremia but no noncarriers with low-grade iron content did
(P = .07). All noncarriers who became infected had high iron content
(grade > or = 2) of the hepatic explant. A readily quantifiable
assessment of hepatic iron at the time of transplantation can
potentially identify patients without carriage who may be at risk for
early S aureus bacteremia.
