Role of iron in the treatment of sepsis

Iron is an important microelement in human and microbial life activities. During the pathophysiological process of sepsis, iron metabolism changes and the body undergoes a series of changes to fight microbial infection. Meanwhile, alterations in iron metabolism during sepsis lead to the development of some diseases, such as transfusion-induced siderosis and anemia. In recent years, several studies have demonstrated the use of iron-chelating agents to fight microbial infections, and new antimicrobial agents have been developed using "Trojan horse" and siderophores immunity. In addition, the use of iron-based nanomaterials as drug delivery systems for gene delivery may be applied to the treatment of sepsis in the future. In this review, we describe the pathophysiological changes in the development and course of sepsis, focusing on the potential of iron in the treatment of sepsis.
