OBJECTIVE The impact of endogenous immunoglobulin isotypes on the prognosis of patients with severe sepsis has not been sufficiently explored. The aim of this study was to evaluate the association between immunoglobulin levels in plasma and survival in patients with this condition. DESIGN AND PATIENTS A prospective multicentre cohort study was conducted.(More)
INTRODUCTION Host immunity should play a principal role in determining both the outcome and recovery of patients with sepsis that originated from a microbial infection. Quantification of the levels of key elements of the immune response could have a prognostic value in this disease. METHODS In an attempt to evaluate the quantitative changes in the status(More)
OBJECTIVES Although there is general agreement on the characteristic features of the acute respiratory distress syndrome, we lack a scoring system that predicts acute respiratory distress syndrome outcome with high probability. Our objective was to develop an outcome score that clinicians could easily calculate at the bedside to predict the risk of death of(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)
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)
OBJECTIVE We analyze the most suitable time to perform tracheostomy in neurocritically ill patients. We compare morbimortality and use of resources between those patients in which tracheostomy was done early (<or= 9 days) and those in which it was perform later (>9 days), in a selected group of patients. MATERIAL AND METHODS We made an observational(More)
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)
Plasma immunoglobulin concentrations are acutely altered in critically ill patients with sepsis. However, the association between immunoglobulin levels on the day of sepsis diagnosis and subsequent mortality is inconsistent. Systematic review of studies that report immunoglobulin measurements and mortality among adults with sepsis managed in a critical care(More)
PURPOSE There is increasing evidence on the relationship between endogenously produced immunoglobulins and the clinical outcome in septic shock (SS). MATERIALS AND METHODS Levels of immunoglobulin G (IgG) subclasses, immunoglobulin A (IgA), immunoglobulin M (IgM), and immunoglobulin E were measured in plasma from 42 patients with SS and in 36 patients(More)
