Delta neutrophil index versus lactate clearance: Early markers for outcome prediction in septic shock patients

Is lactate clearance impaired in septic shock?

In a recent article in Critical Care, Tapia and colleagues evaluated the relationship between exogenous lactate clearance and liver perfusion in a short-term model of endotoxemic shock [1]. The authors concluded that the very low portal-hepatic vein lactate gradient was indicative of the inability of the liver to metabolize the increased lactate load. Although we believe that the authors addres...

Early lactate clearance is associated with improved outcome in severe sepsis and septic shock.

OBJECTIVE Serial lactate concentrations can be used to examine disease severity in the intensive care unit. This study examines the clinical utility of the lactate clearance before intensive care unit admission (during the most proximal period of disease presentation) as an indicator of outcome in severe sepsis and septic shock. We hypothesize that a high lactate clearance in 6 hrs is associate...

Pentraxin-3, procalcitonin and lactate as prognostic markers in patients with sepsis and septic shock

The purpose of this study was to confirm the prognostic value of pentraxin-3 (PTX3), procalcitonin (PCT) and lactate in patients with severe infections requiring ICU management and to develop and validate a model to enhance mortality prediction by combining severity scores with biomarkers. We included 141 patients with the diagnosis of sepsis/septic shock. The levels of PTX3, PCT and lactate we...

Cellular and Molecular Markers of Outcome in Septic Shock

Reversal of neutrophil-to-lymphocyte count ratio in early versus late death from septic shock

INTRODUCTION Septic shock is one of the most frequent causes of admission to the intensive care unit (ICU) and is associated with a poor prognosis. Early and late death in septic shock should be distinguished because they may involve different underlying mechanisms. In various conditions, the neutrophil-to-lymphocyte count ratio (NLCR) has been described as an easily measurable parameter to exp...
