Abstract

Background: To evaluate the prognostic value of endotoxin activity assay (EAA) in adult patients with suspected or proven severe sepsis after cardiac surgery

Methods: Blood samples taken from 81 patients immediately after the diagnosis of severe sepsis were tested with the EAA. Patients were divided into 3 groups: low (<0.4, n = 20), moderate (0.4-0.59, n = 35) and high (≥0.6, n = 26) EAA levels.

Results: Gram-negative bacteraemia was found in 19/55 (35%) of cases with ЕАА <0.6 and in 11/26 (42%) of cases with higher ЕАА, p = 0.67. Mortality at 28 days in Groups 1, 2 and 3 was 20%, 43% and 54%, respectively. Patients with an EAA higher than 0.65 had a higher 28-day mortality than those with lower EAA values (18/26 - 69% vs. 19/55 - 34.5%; p = 0.0072). ROC analysis for the prediction of 28-day mortality revealed an AUC for APACHE II scores, EAA and PCT of 0.81, 0.73 and 0.66, respectively.

Conclusions: EАА might be useful for recognising patients who have an increased risk of mortality due to severe sepsis.
