Skeletal Muscle and Platelet Mitochondrial Dysfunction During Sepsis
Severe SepsisSeptic ShockThe primary aim of the study is to demonstrate that mitochondrial dysfunction occurs in both skeletal muscle and circulating platelets of severely septic and septic shock ICU-admitted patients. Secondary aims are to clarify the pathogenesis and the clinical relevance of mitochondrial damage during sepsis.
Benefit of SeptiFast Multiplex PCR in the Etiologic Diagnosis and Therapeutic Approach for Onco-hematology...
Hematologic DiseasesSepsisA SpetiFast multiplex PCR kit has recently been placed on the market witch can evidence the DNA of 90% of micro-organisms (bacteria and fungus) implicated in sepsis. However, the clinical impact of being able to detect the DNA of these various agents is unknown. We propose to assess the benefit to patient care of the SeptiFast multiples PCR by answering three questions : 1/in patients with septic immunosuppression, does this kit evidence etiologic agents not revealed by classical methods? 2/Does the use of PCR results permit different diagnostic hypotheses to be considered? 3/Does having the SeptiFast results entail changes to the therapeutic plan?
Defects in Opsonophagocytosis in Premature Infants
PrematurityNeonatal SepsisThe purpose of the study is to characterize innate immune function of premature infants, and identify defects that may be responsible for the development of bacterial sepsis.
Inflammatory Cytokine Quantification in Infants
SepsisCongenital Diaphragmatic Hernia1 moreThis study proposes to quantify inflammatory cytokine profiles in three neonatal disease states, namely, neonatal sepsis, infants with a congenital diaphragmatic hernia defect, and infants suffering cardiopulmonary failure significant enough to require heart/lung bypass treatment with extracorporeal membrane oxygenation (ECMO).
Time Course of Procalcitonin and C Reactive Protein in Septic Patients Under Treatment With Corticosteroids...
SepsisA systemic treatment with corticosteroids has been advocated for various bacterial infectious diseases. Since the production of CRP is down-regulated by corticosteroids, a smaller increase or a more rapid decrease of this acute phase protein will: suggest attenuated systemic inflammation, but does not necessarily reflect adequate therapy of the infection. For several reasons (good diagnostic tool for sepsis, induction not decreased by immunosuppressive therapy), procalcitonin could be a better marker for activity of sepsis in patients under corticosteroids. As this issue has not yet been examined the investigators will prospectively study the time-course of PTC and CRP in a well-defined septic patient group, that in adjunction to antibiotic therapy also received systemic corticosteroid treatment and compare it to a similar group without corticosteroid treatment.
Heparin Binding Protein as a Prognostic Biomarker of Sepsis Severity
SepsisHBPthe aim of the study is to correlate between the severity of sepsis and serum heparin binding protein in the patients admitted to ICU with sepsis., and detect its value as a prognostic biomarker in sepsis
Electroencephalographic Patterns of Septic Patients and Its Correlation With Cognitive Outcomes...
SepsisThe investigators evaluated the electroencephalographic pattern by the Sinek and Young scales during ICU stay and its correlation with cognitive impairment determined by the Montreal Cognitive Assessment (MOCA) in septic patients after 3 months of ICU discharge..
Peripherel Perfusion Index to Predict Sepsis in Very Low Birth Weight Infants
VLBW - Very Low Birth Weight InfantTo explore the predictive value of peripheral perfusion index in late onset sepsis of very low birth weight infants , obtain the threshold by observing the perfusion index of very low birth-weight infants within one month after birth, this value can be used as a threshold to predict late onset sepsis in very low birth weight infants.
Dynamic Changes of Tim-3 on Monocytes and Soluble Tim-3 in Patients With Sepsis
SepsisSevere Sepsis1 moreIn this study, the investigators will dynamically detect the expression of an immune regulator- T cell Ig and mucin domain protein 3 (Tim-3) in patient with sepsis.
Early PREdiction of Severe Sepsis I (ExPRES-Sepsis I) Study
SepsisBetween 6 and 16% of patients presenting to hospital emergency departments have infections, with half of these having signs of systemic inflammation (known as 'sepsis'). A second issue is that, at time of presentation, it can be difficult to determine who has inflammation as a result of infection and who does not. Some of the patients with infections will deteriorate to organ failure ('severe sepsis') including failure of the heart and blood vessels to maintain normal blood pressure ('septic shock'). Septic shock as arguably the most dangerous form of severe sepsis is associated with a significant mortality, which can be reduced by early intervention. However identifying those patients who are at high risk of deteriorating to septic shock can be difficult on initial presentation to hospital, and thus these patients risk being 'triaged' to an inappropriate level of care and/or missing the crucial early interventions which can modify mortality. Equally failure to identify which patients have underlying infections can lead to potential inappropriate targeting of antibiotics. Existing clinical and laboratory tests are often unable to accurately identify those patients with infection, and those who are likely to deteriorate to severe sepsis and septic shock. Investigators in this group have recently identified several signatures of immune system activation which predict those patients who are likely to deteriorate, and which patients with suspected infection subsequently have this confirmed. Such tests would have major benefits for the management of patients with early suspected infection and sepsis if they can be translated into a test usable in everyday clinical practice. This study aims to determine the prevalence of these markers in a cohort of patients admitted with suspected sepsis, and their predictive ability for developing established septic shock. From this investigators aim to derive an optimal test, to be tested in a validation cohort (ExPRES-Sepsis II) which will be suitable for everyday clinical practice, and thus take the next step towards developing a market-ready test. Study hypothesis is: Measurement of markers of immune activation will allow i) Risk stratification for deterioration into severe sepsis ii) Risk stratification for death amongst patients presenting with sepsis iii) Identification of patients with confirmed sepsis
