BACKGROUND: Detection of an eventful course in the early days of sepsis treatment is clinically relevant. The white blood cell count (WBCC) and C-reactive protein (CRP) are used in daily practice to monitor the intensity of the inflammatory response associated with sepsis. It is not entirely clear which of the two might better discriminate the outcomes of patients with sepsis.

METHODS: 30-day mortality was assessed in a cohort of patients who were hospitalized with sepsis in the departments of Internal Medicine in a tertiary medical center. Admission and 72-hour time points were analyzed to discriminate between patients with increased versus decreased 30 days mortality risk.

RESULTS: The study included 195 patients. Higher 72h CRP, WBCC, neutrophil counts and neutrophils to lymphocyte ratio were associated with increased mortality (p<0.02). Baseline WBCC and CRP failed to discriminate between patients who died and those who survived (AUC=0.551, 0.479). In multivariate analysis of the 72h tests, higher WBCC count (OR= 1.12, 95%CI 1.05-1.20, p=0.001), was associated with increased mortality whereas CRP was not (OR=1.004, 95%CI 0.998-1.01, p=0.146).

CONCLUSION: Patients who presented a 72-hour leukocyte descent had a better outcome and in this regard, WBCC was superior to 72-hour CRP in predicting 30 days mortality.
