Filter by:Microparticules (MPs) result from plasma cell membrane remodeling and shedding after cell stimulation or apoptosis. MPs are know recognized as a pool of bioactive messengers with merging role in pathophysiology of immune and cardiovascular diseases. MPs have been characterized during septic shock and may contribute to dissemination of pro-inflammatory and procoagulant mediators. This a prospective observational study of circulating MPs and blood coagulation in septic shock patients admitted in medical intensive care units (ICUs) of four tertiary hospitals at baseline (D1, D2, D3, D4, D7).
The main goals of this study are to provide a cognitive, neurological, brain morphological, and serological profile of sepsis survivors in order to make long-term prognosis of recovery and estimate the need for rehabilitation measures in order to help patients reintegrate into normal daily life.
The purpose of this study, in mechanically ventilated septic shock patients, is to determine whether a fluid loading strategy based on parameters derived from the transpulmonary thermodilution technique may lead to more ventilator free days compared to a fluid loading strategy based on the surviving sepsis guidelines.
BACKGROUND: Echocardiography can provide evaluation of right or left ventricular dysfunction and volume status during resuscitation of patients with sepsis and septic shock and guide intravenous vasopressor and fluid therapy. While there are numerous echocardiographic studies regarding cardiac function and volume status in patients with established shock, there are none that describe these during the early resuscitation of septic shock. The study objective is to correlate echocardiographic findings with clinical parameters and net fluid balance measured during the early resuscitation of critically ill patients with sepsis and septic shock. Aim 1) correlate echocardiographic findings of cardiac function with physiologic markers in the early hours of resuscitation Aim 2) correlate cardiac function and fluid status with clinical outcomes Aim 3) evaluate the change in cardiac function over time in patients with sepsis and septic shock Aim 4) evaluate long term clinical outcomes for patients with sepsis and septic shock.
The investigators hypothesis is that for ICU patients with shock, the use of the vasoactive drugs phenylephrine and vasopressin will reduce tachydysrhythmias when compared to norepinephrine and epinephrine. To investigate this hypothesis, the investigators are conducting a randomized double blind controlled trial comparing phenylephrine and vasopressin vs. norepinephrine and epinephrine in ICU patients with shock that is not responsive to IV fluids. All patients admitted to the adult intensive care units at the University of Chicago will be screened for eligibility.
Beta adrenergic system, over-activated in septic shock patients, is a key modulator of the inflammatory response. Experimental works demonstrated that Esmolol, an highly selective beta-1 blocker, reduces heart rate and regulates the inflammatory response. A recent mono centric, double blind, randomized clinical work in septic shock patients has shown that Esmolol administration is safe and reduces effectively heart rate. However there are only sparse data on 1) regional and micro-circulation, 2) inflammation modulation in human resuscitated septic shock patients treated by esmolol.
To observe the effect of early goal directed therapy (EGDT) on hepatic perfusion in patients with septic shock. Hypothesis: Hepatic perfusion did not improved after EGDT in patients with septic shock.
Record the renal resistive index and hemodynamic parameters ( record the cardiac output and stroke volume if the patient's next to kin agree to undertake a PiCCO monitoring ) before and after resuscitation for severe sepsis or septic shock patients, to determine whether the changes of resistive index or hemodynamic parameters, especially the cardiac output can be a better parameter to predict AKI
Septic shock remains a significant clinical problem associated with high rates of mortality among neutropenic patient despite antimicrobial therapy and supportive care. Recently, mesenchymal stromal cells (MSC) have demonstrated remarkable potential effect in sepsis. MSC treatment significantly reduced mortality in septic mice receiving appropriate antimicrobial therapy. MSCs reduced systemic inflammatory cytokine levels in mice, down-regulated of inflammation and inflammation-related genes (such as interleukin-10, interleukin-6). Bacterial clearance was greater in MSC-treated mice. Thus, MSCs have beneficial effects on experimental sepsis and suggest that MSСs-therapy may be an effective adjunctive treatment to reduce sepsis-related mortality. The safety of MSCs is proved by Graft-versus-host disease treatment MSCs in patients after bone marrow transplantation. This study hypothesis is that MSCs reduce organ dysfunction/injury, systemic inflammation and mortality in patients with septic shock and severe neutropenia. The main goal of the study is to evaluate the impact of MSCs therapy on organ dysfunction/injury, systemic inflammation and 28-day mortality in patients with septic shock and severe neutropenia. All patients will be randomized in two groups: control group (standard treatment of septic shock) and MSCs-group (standard treatment of septic shock + MSCs infusion of 1-2 millions/kg/ day).
The purpose of this study is to compare the tendency of plasma concentration and clearance of procalcitonin in the first 24 and 48 hours of management of patients with severe sepsis and septic shock with another marker of early prognosis represented by 48 hours delta sofa.
