摘　　要：Iron is a double-edged sword!Despite being essential for numerous physiological processes of the body,a dysregulated iron metabolism can result in tissue da-mage,exaggerated inflammatory response,and increased susceptibility to infection with certain pathogens that thrive in iron-rich environment.During sepsis,there is an alteration of iron metabolism,leading to increased transport and uptake into cells.This increase in labile iron may cause oxidative damage and cellular injury(ferroptosis)which progresses as the disease worsens.Critically ill patients are often complicated with systemic inflammation which may contribute to multiple organ dysfunction syndrome or sepsis,a common cause of mortality in intensive care unit.Originally,ferritin was known to play an important role in the hematopoietic system for its iron storage capacity.Recently,its role has emerged as a predictor of poor prognosis in chronic inflammation and critical illnesses.Apart from predicting the disease outcome,serum ferritin can poten-tially reflect disease activity as well.
