Assessment of Fluid Responsiveness in Septic Shock Patients, Can End-tidal co2 Measurement Help?...

Septic ShockHypovolemia1 more

Fluid therapy is important in patients with sepsis and septic shock. There are many invasive and non-invasive methods to assess fluid responsiveness in patients. The specificities and sensitivities of these methods are highly variable. The reason for our study was to determine end-tidal co2 and fluid responsiveness in septic shock patients. The aim of the study was to evaluate the fluid response using the End-tidal CO2 difference in septic shock patients receiving intubated mechanical ventilation support.

Diastolic Dysfunction in Septic Shock and Cardiomyopathy Genetic Variants

Diastolic DysfunctionSeptic Shock1 more

Sepsis is a life-threatening infection with increasing incidence, and its spectrum of disease can involve cardiac dysfunction, which further adds to mortality. Although cardiac involvement in sepsis has been classically attributed to systolic dysfunction, diastolic dysfunction is increasingly diagnosed due to new echocardiographic techniques and the conceptual evolution of diastolic dysfunction. Combining systolic and diastolic dysfunction assessment could lead to a better diagnosis of septic cardiac dysfunction. Furthermore, earlier forms of septic cardiac dysfunction could be more promptly recognized by measuring novel and less used parameters of diastolic dysfunction. We hypothesize that left atrium (LA) strain and isovolumetric relaxation time (IVRT) derived intervals could be new and earlier predictors of diastolic dysfunction in septic patients with a potential impact on clinical presentation and prognosis and that rare genetic variation associated with inherited cardiomyopathies could underline the risk and severity of sepsis-related myocardial dysfunction with potential impact on diagnosis and prognosis.

Nasal and Gut Microbiota Combined Clinical Events Predicts the Prognosis of Septic Patients

SepsisSeptic Shock

In this prospective, multicentered , diagnostic trial, nasal and fecal specimens will collected from patients with sepsis in two critical care units(ICU) at the enrollment day ,the third, seventh, and fourteen days after enrollment or until ICU discharge (whatever come first). Total DNA from the nasal and fecal specimens will be extracted, amplified, and sequenced to determined the characteristics of gut microbiota and nasal microbiota. Finally, the characteristics of gut microbiota and nasal microbiota combined clinical information will be used to construct a prediction model to predict the prognosis of sepsis.

Simplified Assessment of Left Ventricular Systolic Function in Septic Shock Patients

Left Ventricular Systolic DysfunctionSeptic Shock

The assessment of left ventricular systolic function is based on the measurement of left ventricular ejection function (LVEF) by the Simpson biplane method. More recently, left ventricular global longitudinal strain (GLS) has been developed to detect abnormalities of cardiac contractility in patients with preserved myocardial contractility. However, both tools are not always easy to collect in practice. This is why other ultrasound parameters have been proposed in the literature as a substitute for LVEF and GLS such as the Doppler tissue imaging (DTI)-derived mitral annular systolic peak S-wave velocity (S'), the mitral annular plane systolic excursion (MAPSE) and the longitudinal wall fractional shortening index (LWFS). The purpose of this project is to propose an algorithm using simple parameters (S' wave, lateral MAPSE, septal MAPSE, mean MAPSE and LWFS) to predict LVEF and GLS in order to diagnose patients with impaired systolic function and preserved ejection.

Role and Mechanisms of Lipid and Lipoprotein Dysregulation in Sepsis

SepsisShock1 more

Lipids and lipoproteins (cholesterol and lipid metabolites) are present in sepsis and are highly biologically active regulators of inflammation, but currently the changes in lipid and lipoprotein homeostasis during sepsis are not well understood. This project will investigate the changes in lipid and lipoprotein function, oxidation, metabolites, and changes in gene expression to further our understanding of dysregulated lipid and lipoprotein metabolism in sepsis. We will analyze a bank of samples and make associations with important clinical outcomes (early death, chronic critical illness and sepsis recidivism) as supported by our published work, and will confirm our findings in a small prospective cohort of sepsis patients.

Assessment of Microcirculatory Dysfunction in Septic Shock Patients by OCTA

Septic Shock

Purpose and rationale: Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection. Sepsis and septic shock are major public health problems killing one in every three patients. Microcirculatory dysfunction is frequent in septic shock. The duration and severity of this dysfunction have a prognostic impact by being associated with organ failure and mortality. Our study purposes to demonstrate the feasibility of optical coherence tomography angiography (OCTA) to improve assessment of microcirculatory dysfunction by showing that retinal and choroidal microcirculatory changes with prognostic impact are present during septic shock. Primary objective: To characterize the alterations of retinal and choroidal microcirculation in septic shock. We will test the hypothesis that retinal and/or choroidal microcirculation shows dysfunctional changes (lower vascular density, lower percentage of perfused small vessel, lower blood flow index and higher vascular heterogeneity) in septic shock patients. Secondary objective: To test the prognostic value of retinal and choroidal microcirculatory dysfunction in septic shock. We will test the hypothesis that higher magnitude and persistence of retinal and/or choroidal microcirculatory dysfunction beyond the successful macro-hemodynamic resuscitation are independent predictors of organ failure and mortality in septic shock patients. Study type: Two sequential observational studies. Study design: A cross-sectional case-control study followed by a prospective cohort study with a 90-days longitudinal follow-up period. Study population: 165 septic shock patients and 30 healthy controls. Study duration: 90 days from enrolment to final follow-up assessment. One to two years of enrolment.

Impact of Metabolite Supplementation to Restore Mitochondrial Dysfunction During Septic Shock: a...

Septic ShockMultiple Organ Failure

Septic shock is defined as a subset of sepsis with severe metabolism alterations, leading to organ failure. Septic shock is associated with a high mortality, around 40% according to the SEPSIS 3 definition. Metabolic alterations are responsible for lactic acidosis, and results in mitochondrial dysfunction. This study aims at evaluate the impact of exogenous metabolites on restoring mitochondrial function in septic shock patients with lactate acidosis. Mitochondrial metabolism (quantitative analysis, mitochondrial function) in intact Peripheral Blood Mononuclear Cells (PBMC) will be isolate and analyse from patients at the early phase of septic shock (admission), at day 2 and 4. Participant's medical history will be recorded: renal and liver metabolism, severity scores and outcomes and the need for supportive care in the intensive care unit (ICU) until 28 days after admission. Furthermore, the investigators will evaluate wether selected metabolites added to the cell culture medium may improve mitochondrial metabolism.
