Background: We aimed to investigate the role of angiopoietin (Angpt) as a predictive biomarker for sepsis by evaluating associations between plasma Angpt and various inflammatory cytokines and mortality in critically ill patients with sepsis. Methods: This study was a retrospective cohort study of the prospectively collected samples and clinical data of 145 patients with sepsis who were admitted to the medical intensive care unit (ICU) of a 2000-bed university tertiary referral hospital in South Korea. We collected plasma within 24 h of medical ICU admission, and several biomarkers (Angpt-1 and -2, Tie2, vascular endothelial growth factor, interleukin (IL)-1β, IL-10, IL-18, IL-6, interferon gamma-induced protein-10, and tumor necrosis factor-α) were measured using a Human Magnetic Luminex Screening Assay kit. Results: Plasma Angpt-2 was correlated with IL-6 (rs = 0.555) and tumor necrosis factor-α (rs = 0.559). Plasma Angpt-2 (rs = 0.530) and Angpt-2/1 (rs = 0.562) were correlated with the Sequential Organ Failure Assessment (SOFA) score. The area under the curve (AUC) for the 28-day mortality prediction for the plasma Angpt-2/1 ratio was 0.736; AUCs for the Acute Physiology and Chronic Health Evaluation II (APACHE II) and SOFA scores were 0.659 and 0.745, respectively. Using multivariate Cox proportional hazard regression analysis for 28-day mortality, we found that acute respiratory distress syndrome (hazard ratio (HR) = 2.235, 95% CI = 1.163-4.296,p = 0.016), APACHE II score (HR = 1.127, 95% CI = 1.037-1.224,p = 0.005), and Angpt-2/1 > 3.2 (HR = 2.522, 95% CI = 1.205-5.278,p = 0.014) were risk factors for 28-day mortality. Conclusions: Plasma Angpt-2 was related to cytokines, but Angpt-2/1 ratio was a good predictor of 28-day mortality in patients with sepsis.
