{Abstract}: <B>BACKGROUND: </B>We determined whether plasma concentrations of ZO-1 proteins may be used a predictor of sepsis severity and 30-day mortality.<BR><B>METHODS: </B>A total of 143 patients with sepsis and 30 healthy controls were enrolled. Plasma ZO-1 proteins concentrations were measured. Various methods, including area under the curves (AUCs), Kaplan-Meier curve, Cox regression, net reclassification improvement (NRI) and integrated discrimination improvement (IDI), were carried out to determine the value of ZO-1 in predicting 30-day mortality.<BR><B>RESULTS: </B>Plasma ZO-1 concentrations in patients with sepsis and septic shock were significantly higher than those in healthy controls and were associated with the number of organ failures. ZO-1 concentrations also correlated with APACHE II or SOFA score and predicted 30-day mortality in sepsis patients with an AUC of 0.754. Multivariable regression analyses showed that a ZO-1 concentration ≥2.60 ng/ml remained a significant predictor of 30-day mortality in sepsis patients. Kaplan-Meier survival plots showed that patients with ZO-1 concentrations <2.60 ng/ml had a clear survival benefit. Adding ZO-1 to the SOFA score significantly improved its prognostic accuracy.<BR><B>CONCLUSIONS: </B>Plasma ZO-1 proteins appear to be a valuable prognostic biomarker for the severity of sepsis and a predictor of 30-day mortality for patients with sepsis.
