Core Tip
Core tip: Iron is an essential element for many biological functions. Its deficiency or overload is associated with poor outcomes in many settings. Few data are available in patients undergoing liver transplantation, and more specifically on infection related deaths. Our study is the first to describe in a large number of patients, the impact or iron metabolism imbalance on mortality after liver transplantation. Our results show that both iron deficiency and overload are significantly associated with increased mortality. Further we show that transferrin saturation higher than 75% is associated with mortality.
