Filter by:Less than ten years after their intial description, the comprehension of Innate Lymphoid Cells (ILCs) biology is rapidly improving. They can be classified into four subgroups (ILCs 1, 2, 3 and NK cells) on the basis of their cytokine production and transcription factor expression. They seem to be players in infectious diseases in animals but their role in human anti-bacterial defense remains unknown. In this prospective work, the investigators will compare ILCs phenotyping in ICU patients managed for a septic shock, comparing them to ICU patients without any infectious disease on their inclusion. The investigators will also make a large immune mapping in all patients, to place ILCs in the global immune depressed state observed in septic patients.
the investigators will include 120 patients with a diagnosis of septic shock in accordance with the definition given by the 2001 expert consensus. Two groups of patients are likely to participate in this study: Patient hospitalized in intensive care for a septic shock = Primary patient + patient who develops, the waning of his hospitalization in intensive care for another reason, a septic shock = Secondary patient. Haemodynamic monitoring by transpulmonary thermodilution allow a patient's close monitoring during the initial phase supported. The clinical and biological data, demographic and the severity scores are collected for each patient during the first three days of stay. To predict the unfavorable evolution of the patients, a measure of the SOFA score at the input (J0) and third day (J2) is performed. the investigators analyzed mortality at day 28 in patients with increased P₍ᵥ₋ₐ₎CO₂ and those with increasing of organ failure. This research will be conducted according to good clinical practice. An information will be distributed to patients.
The aim of this project is to constitute a prospective cohort of all the patients presenting to the adult emergencies of the University Hospital Centre (CHU) of Rennes for a septic syndrome of community origin.
Background: Central Venous catheter insertion technique and indwelling time are major risk factors for CVC colonisation. Colonisation occurs through microbial migration and biofilm formation along the catheter insertion tract. This study set out to determine the prevalence and associated factors for central venous catheter colonisation among critically ill patient. No data exists in this clinical setting addressing this topic. Methods: The study population included 100 participants with central venous catheters in situ for at least 24 hours. Catheter tip (distal 5-cm segment) and blood cultures (10mls peripheral blood) were obtained at the time of catheter removal.
In this prospective clinical study, the investigators compare the outcome and clinical course of consecutive septic participants treated with intravenous vitamin C, hydrocortisone, and thiamine (treatment group) with a control group treated in the investigators' ICU. The primary outcome is hospital survival. A propensity score is generated to adjust the primary outcome.There is 70 participants in each group.
Septic shock is responsible in 20% of cases of acute adrenal insufficiency and in 50% of cases of chronic 'slow' adrenal insufficiency. Given the unpredictable nature of the response to the ACTH stimulation test, it is recommended to systematically start steroid replacement therapy with hydrocortisone hemisuccinate (HCHS) in patients in septic shock who do not respond to fluid resuscitation and who continue to suffer from haemodynamic instability despite increasing doses of noradrenaline. The interest of this corticosteroid therapy lies in its ability to reduce the duration of treatment with catecholamines, though the results are conflicting with regard to an eventual benefit for mortality. Steroid replacement therapy may be deleterious. It may increase the risk of sepsis and secondary septic shock. It is also implicated in critical-illness polyneuropathy and blood glucose dysregulation. Today, there is no way to identify a population of patients who respond to corticosteroid therapy. From a pathophysiological viewpoint, HCHS, as well as its glucocorticoid effects, may also exert mineralocorticoid effects able to compensate for the impaired renin angiotensin aldosterone system (RAAS), which is responsible for the refractory aspects of septic shock. This hyperreninism-hypoaldosteronism is found with a prevalence of around 50% of cases and is defined by a plasma aldosterone/ plasma renin ratio < 2. It is associated with natriuresis >30 mmol/l. We hypothesise that natriuresis > 30 mmol/l will make it possible to identify patients who respond to steroid replacement therapy in terms of catecholamine use.
This translational study will assess the association between septic cardiomyopathy (measured via left ventricular global longitudinal strain) and (a) inflammatory cytokine profiles, and (b) the behavior of cardiomyocytes derived from inducible pluripotent stem cells.
The aim of this work is to compare two protocols (ketamine-midazolam versus fentanyl-midazolam) for induction of anesthesia in patients with septic shock aiming to find the most safe protocol with regards to hemodynamic status of patients
The prevalence and mortality of sepsis in Turkey is not know at large. Turkish Society of Intensive Care Medicine, Sepsis Study Group conducted a multi-centre,point prevalence survey to determine the prevalence, causative micro-organisms and outcome of sepsis in Turkish ICUs.
Post extubation respiratory failure occur in 30% of extubated patients. More than 50% of them required reintubation. Noninvasive positive pressure ventilation (NIV) had been reported as an effective tool to prevent post extubation respiratory failure. Recently, high flow oxygen nasal cannula (HFNC) had been successfully used to prevent post extubation respiratory failure and prevent reintubation in comparable with NIV among post cardiothoracic surgery and high risk for reintubated patients. There was no information about HFNC versus NIV in prevention of reintubation among severe sepsis or septic shock patients.
