Abstract

Sepsis is a life-threatening condition caused by a dysregulated response of the body in response to an infection that harms its tissues and organs. Interleukin-6 (IL-6) is a significant component of the inflammatory response as part of the pathogenesis of sepsis. It aids in the development of Acute lung injury and, subsequently, multiple organ dysfunction syndrome. This letter probes into the correlation between plasma IL-6 levels and the risk of developing acute lung injury and multiple organ dysfunction syndrome in critically ill patients with sepsis. While it shows promising results, limitations like its observational study design, a limited sample size, a single center involvement, single-time-point measurement, and a lack of a control group restrain its cogency. The study is a big step in identifying IL-6 as a biomarker to improve patient care.

Keywords: Sepsis; Acute lung injury; Multiple organ dysfunction syndrome; Interleukin-6; Biomarker; Critical illness

Core Tip: The study explores the association of interleukin-6 levels with the risk of developing acute lung injury and multiple organ dysfunction syndrome in critically ill sepsis patients. It underscores its potential as a valuable biomarker for prognosis and guiding treatment in intensive care settings. However, limitations like an observational study design, a limited sample size, a single center involvement, single-time-point measurement, and no control group should be considered in further research.
