ObjectivesTo investigate whether stress hyperglycemia affects the production of the main pro- and anti-inflammatory cytokines and the 28-day hospital mortality in patients with severe sepsis.MethodsThe study included 62 patients with severe sepsis, divided in three groups according to their glycemic profile within 24h after admission: patients with stress hyperglycemia (group SH, n=16), diabetes mellitus type II (group DM, n=27), and normal glucose levels (group NG, n=19). The serum levels of the cytokines TNF-alpha, IL-6, IL-10 and TGFbeta-1 were measured within 24h after admission.ResultsA higher percentage of septic patients with stress hyperglycemia died compared to diabetic patients (43.7 vs. 14.8%) and group NG (43.7 vs. 5.2%). Group SH had higher SOFA score and levels of IL-6 and IL-10 than group DM and group NG. It also had higher levels of TNF-alpha than group DM but not group NG. There was no difference in the levels of TGFbeta-1 among the three groups. Non-survivors had higher levels of IL-10, no difference was detected for IL-6, TNF-alpha, IL-10/TNF-alpha ratio and TGFbeta-1. Interleukin-10 values, mean fasting glucose values and age were found as prognostic factors associated with outcome.ConclusionsStress hyperglycemia is associated with increased cytokine production and an adverse clinical outcome in patients with severe sepsis.
