Iron Metabolism in the Recovery Phase of Critical Illness with a Focus on Sepsis.
Study Goal
The researchers aimed to review current knowledge about iron-related biomarkers in critical illness, particularly sepsis, and provide criteria for iron supplementation during the recovery phase.
Results Summary
The study highlights that iron deficiency in critically ill patients, especially during recovery, can lead to adverse outcomes like cognitive dysfunction and fatigue, emphasizing the need for timely treatment. However, iron supplementation during the acute phase is discouraged due to risks of increased microbial iron availability and oxidative stress.

Iron is an essential nutrient for humans and microbes, such as bacteria. Iron deficiency commonly occurs in critically ill patients, but supplementary iron therapy is not considered during the acute phase of critical illness since it increases iron availability for invading microbes and oxidative stress. However, persistent iron deficiency in the recovery phase is harmful and has potential adverse outcomes such as cognitive dysfunction, fatigue, and cardiopulmonary dysfunction. Therefore, it is important to treat iron deficiency quickly and efficiently. This article reviews current knowledge about iron-related biomarkers in critical illness with a focus on patients with sepsis, and provides possible criteria to guide decision-making for iron supplementation in the recovery phase of those patients.
