Clinical evaluation of Sepsis-1 and Sepsis-3 in infective endocarditis

Abstract

BackgroundSepsis is associated with poor survival outcomes in patients with infective endocarditis (IE). However, the prognostic value of the Sepsis-1 and Sepsis-3 criteria of sepsis for IE patients is unclear. MethodsA total of 1354 patients with IE was enrolled and classified into the sepsis and non-sepsis groups according to the Sepsis-1 and Sepsis-3. Multivariate regression analysis was performed to test the predictive performances of the Sepsis-1 and Sepsis-3 in assessing the risk of mortality in patients with IE. ResultsSepsis was diagnosed in 347 (25.6%) patients according to the Sepsis-1 and 496 (36.6%) patients with the Sepsis-3. The in-hospital mortality rate was 11.5% in the Sepsis-1 group and 14.3% in the Sepsis-3 group. Kaplan-Meier survival curve analysis showed that both Sepsis-1 (Log-rank = 17.2, p < 0.001) and Sepsis-3 (Log-rank = 94.3, p < 0.001) were significantly associated with 6-month mortality. Multivariate regression analysis demonstrated that the Sepsis-3 was independently associated with the in-hospital mortality (odds ratio = 2.89, 95% CI 1.68–4.97, p < 0.001) and the 6-month mortality (hazard ratio = 3.24, 95% CI 2.08–5.04, p < 0.001). ConclusionsSepsis-3 shows better predictive performance than Sepsis-1 criteria in assessing the risk of mortality in patients with IE.
