Abstract

Objective: To evaluate the use of serum levels of the immunological biomarker presepsin, in patients diagnosed with bacterial sepsis, who could or could not progress to septic shock.

Materials and methods: An analytical, cross-sectional study was carried out with a sample of 125 individuals with bacterial sepsis, 74 women and 51 men between 22 and 90 years of age, determining the serum concentrations of presepsin, by immunoassay, using the method enzyme-linked immunoassay. For data collection, medical records and forms were used to collect the information.

Results: Of the total number of septic patients, 64% (n=32) of women and 36% (n=18) of men progressed to shock; while, by socioeconomic strata, it was evidenced that in the lower stratum, it was where there was the most progress. The sensitivity and specificity of presepsin progressing to shock were 97.9% and 64.4%, respectively. Serum concentrations of presepsin were found to be significantly higher in patients with septic shock (n=50) compared with septic patients without shock (n=75), mean ± SD: 32.7 ± 19.9 ng /mL vs 12.9 ± 7.4 ng/mL, respectively (p < 0.0001).

Conclusion: The serum levels of presepsin demonstrated high sensitivity and high statistical association, both in sepsis and in the progress of septic shock, therefore, its use in septic patients may be feasible.
