ABSTRACT
BACKGROUND:
Sepsis is a life-threatening condition characterized by a dysregulation of the host response to infection that can lead to acute lung injury (ALI) and multiple organ dysfunction syndrome (MODS). Interleukin 6 (IL-6) is a pro-inflammatory cytokine that plays a crucial role in the pathogenesis of sepsis and its complications.AIM:
To investigate the relationship among plasma IL-6 levels, risk of ALI, and disease severity in critically ill patients with sepsis.METHODS:
This prospective and observational study was conducted in the intensive care unit of a tertiary care hospital between January 2021 and December 2022. A total of 83 septic patients were enrolled. Plasma IL-6 levels were measured upon admission using an enzyme-linked immunosorbent assay. The development of ALI and MODS was monitored during hospitalization. Disease severity was evaluated by Acute Physiology and Chronic Health Evaluation II (APACHE II) and Sequential Organ Failure Assessment (SOFA) scores.RESULTS:
Among the 83 patients with sepsis, 38 (45.8%) developed ALI and 29 (34.9%) developed MODS. Plasma IL-6 levels were significantly higher in patients who developed ALI than in those without ALI (median 125.6 pg/mL vs 48.3 pg/mL; P < 0.001). Similarly, patients with MODS had higher IL-6 levels than those without MODS (median 142.9 pg/mL vs 58.7 pg/mL; P < 0.001). Plasma IL-6 levels were strongly and positively correlated with APACHE II (r = 0.72; P < 0.001) and SOFA scores (r = 0.68; P < 0.001).CONCLUSION:
Elevated plasma IL-6 levels in critically ill patients with sepsis were associated with an increased risk of ALI and MODS. Higher IL-6 levels were correlated with greater disease severity, as reflected by higher APACHE II and SOFA scores. These findings suggest that IL-6 may serve as a biomarker for predicting the development of ALI and disease severity in patients with sepsis.
