OBJECTIVES Immunological dysregulation is now recognised as a major pathogenic event in sepsis. Stimulation of immune response and immuno-modulation are emerging approaches for the treatment of this disease. Defining the underlying immunological alterations in sepsis is important for the design of future therapies with immuno-modulatory drugs. METHODS(More)
OBJECTIVES Sepsis is characterised by the frequent presence of organ failure and marked immunologic alterations. We studied the association between the extent of organ failure and the transcriptomic response of septic patients. METHODS Gene expression profiles in the blood of 74 surgical patients with sepsis were compared with those of 30 surgical(More)
Polynuclear neutrophils can play dual roles in sepsis: on the one hand they mediate major antimicrobial activities and on the other hand they can contribute to the development of multiple organ failure [1]. Nonetheless, in spite of the importance of these cells in sepsis, the influence of the circulating neutrophil count (CNC) on the prognosis of septic(More)
OBJECTIVES To quantify immunological dysfunction in surgical patients with presence/absence of sepsis using a droplet digital polymerase chain reaction (ddPCR) transcriptomic analysis. The study also aims to evaluate this approach for improving identification of sepsis in these patients. BACKGROUND Immune dysregulation is a central event in sepsis.(More)
INTRODUCTION The risk of mortality in cardiac surgery is generally evaluated using preoperative risk-scale models. However, intraoperative factors may change the risk factors of patients, and the organism functionality parameters determined upon ICU admittance could therefore be more relevant in deciding operative mortality. The goals of this study were to(More)
PURPOSE Acute kidney injury (AKI) is a frequent complication after cardiac surgery and is associated with increased mortality. The aim was to design a nondialytic AKI score in patients with previously normal renal function undergoing cardiac surgery. METHODS Data were collected on 909 patients who underwent cardiac surgery with cardiopulmonary bypass(More)

PURPOSE We intended to assess how acute kidney injuy impacts on procalcitonin levels in cardiac surgery patients, with or without infection, and whether procalcitonin might be used as a biomarker of infection in acute kidney injuy. MATERIAL AND METHODS A case-control study was designed which included patients that had had cardiac surgery between January(More)
BACKGROUND Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection, being the primary cause of death from infection, especially if not recognized and treated promptly. The aim of this study was to analyze whether IL-6 rs1800795 polymorphism is associated with septic shock-related death in European white patients(More)
Introduction: A hallmark of sepsis is early onset microvascular dysfunction. However, the mechanism responsible for maldistribution of capillary blood flow is not understood. Evidence suggests red blood cells (RBC) can sense local oxygen (O2) conditions and signal the vasculature, via adenosine triphosphate (ATP), to increase capillary flow. We hypothesized(More)
