Introduction:

Septic shock has been recognized worldwide as a cause of high incidence of mortality. The incorporation of new biomarkers makes it possible to obtain a rapid and accurate diagnosis.

Objective:

To evaluate the usefulness of the leukocyte/eosinophil ratio as a prognostic marker of septic shock.

Methods:

An investigation was carried out in two stages: in the first (the descriptive phase) the clinical and epidemiological characteristics and variations of the laboratory studies were detailed and in the second (the explanatory cohort phase), the predictive value of the leukocytes/eosinopenia biomarker in septic shock was estimated. The eosinophil count was performed and the arithmetic mean was obtained. Relative eosinopenia was considered with eosinophil values below the average.

Results:

The study showed that leukocytosis was 27.4 cells*mm3, hematocrit decreased in 32.2% and decreased platelet number (125.6 cells*mm3) prevail in septic shock. In addition, a decrease in eosinophils (18.5 cells/mcl), an increase in the leukocyte/eosinophil ratio (148.1) and worsening of SOFA (2.8) are reflected. The increase in the leukocyte/eosinophil ratio is correlated with the increase in C-reactive protein and procalcitonin.

Conclusions:

The correlation of leukocytosis and eosinopenia showed the usefulness of the leukocyte/eosinopenia index as a predictor of septic shock.
