Filter by:This phase II trial studies how well early metabolic resuscitation therapy works in reducing multi-organ dysfunction in patients with septic shock. Early metabolic resuscitation is made of large doses of glucose, protein, and essential metabolic molecules that may help lower the effects of septic shock on the body. Giving patients early metabolic resuscitation in combination with standard of care may work better in reducing multi-organ dysfunction syndrome in patients with septic shock compared to standard of care alone.
Octreotide is used to decrease portal pressure of cirrhotic patients admitted for variceal bleeding. When patients are in haemorrhagic shock, the recommended drug to increase arterial pressure is norepinephrine. Microcirculatory effects of octreotide when it is added to noradrenaline has not been investigated yet. The aim of the study is to evaluate the effect of octreotide plus norepinephrine for patient with haemorrhagic shock after variceal bleeding.
The objective of this study is to assess the parathyroid hormone serum concentrations and kinetics in critically ill patients admitted to the intensive care unit due to multi-organ failure and undergoing citrate anticoagulation continuous renal replacement therapy.
The purpose of this study is to determine whether the combination therapy (vitamin C,thiamine and hydrocortisone) is effective in the treatment of septic shock.
Albumin is a key regulator of fluid distribution within the extracellular space and possesses several properties beyond its oncotic activity, including binding and transport of several endogenous molecules, anti-inflammatory and anti-oxidant actions, nitric oxide modulation, and buffer function. The accumulating evidence suggests that supplementation of albumin may provide survival advantages only when the insult is severe as in patients with septic shock. Prospective randomized trials on the possible impact of albumin replacement in these patients with septic shock are lacking. The aim of the study is to investigate whether the replacement with albumin and the maintenance of its serum levels at least at 30 g/l for 28 days improve survival in patients with septic shock compared to resuscitation and volume maintenance without albumin. In this prospective, multicenter, randomised trial, adult patients (≥18 years) with septic shock will be randomly assigned within a maximum of 24 hours after the onset of septic shock after obtaining informed consents to treatment or control groups. Patients assigned to the treatment group will receive a 60 g loading dose of human albumin 20% over 2-3 hours. Serum albumin levels will be maintained at least at 30 g/l in the ICU for a maximum of 28 days following randomization using 40-80 g human albumin 20% infusion. The control group will be treated according to the usual practice with crystalloids as the first choice for the resuscitation and maintenance phase of septic shock. The primary end point is 90 days mortality and secondary end points include 28-day, 60-day, ICU, and in-hospital mortality, organ dysfunction/failure, and length of ICU and hospital stay. In total 1412 patients need to be analyzed, 706 per group. Assuming a dropout rate of 15%, a total of 1662 patients need to be allocated.
Patients with septic shock would be screened. Following this, patients meeting the inclusion and exclusion criteria will be screened and randomized to the two treatment groups. Standard criteria will be considered to define refractoriness to fluids. In all patients, baseline endotoxin activity assay and blood and urine sample will be stored for looking at the effect of therapy on these factors. Septic shock would be defined as clinical construct of sepsis with persisting hypotension requiring vasopressors to maintain MAP>=65 mm of Hg and having a serum lactate >2 mmol/L despite adequate volume resuscitation. Patients assigned to the treatment arm and who do not already have access for dialysis will have a standard hemodialysis catheter inserted in one of the femoral veins by the physician. Hemoperfusion will be carried out for one session within 12 hours for all randomized patient using the adsorption columns for Jianfan Biotechnology Co., Zhuhai, China). The hemoperfusion apparatus will be connected in front of the hemodialyzer in series. The procedure would be done for 2 hours without use of heparin with use of normal saline for pipeline flushing. In patients who also require hemodialysis the dialysis would subsequently be continued. Subsequent sessions of therapy would be done for patients (if required).
To demonstrate that a strategy involving early first-line enteral nutrition is associated with improved preservation of gut mucosa integrity, as assessed based on the plasma citrulline level at H72, compared to a strategy involving early first-line parenteral nutrition

The aim of the work is to investigate the effect of using lidocaine in combination with low dose ketamine in induction of anesthesia for septic shock patients compared to normal dose of ketamine.
Sepsis is an acute pathology defined as an inappropriate response of the host to infection, resulting in the onset of organ failure (Quick SOFA ≥2, or SOFA ≥2). Septic shock is a sepsis associated with an elevation of lactate ≥ 2 mmol / l and an arterial hypotension requiring vasoactive drugs. Several studies highlighted that sepsis is associated with a plasma L-arginine deficiency. This deficiency induces a lower availability of L-arginine for multiple metabolic pathways including those involved in the synthesis of nitric oxide (NO) in the vascular endothelium via NO synthase. NO is the main endogenous vasodilator mediator, a lower synthesis induces a vascular and endothelial dysfunction that can promote the occurrence of an organic dysfunction during sepsis. Decrease in available NO was confirmed in patients with sepsis and appears correlated with severity. L-arginine deficiency can have multiple origins: - L-arginine deficiency resulting from a decrease in endogenous production from citrulline synthesized by the enterocytes. Such enterocyte dysfunction has been confirmed in patients with sepsis and is characterized biologically by elevated plasma levels of I-FABP (intestinal fatty acid binding protein - enterocyte-specific protein, cytolysis marker) and lower than that of citrulline (hypocitrullinemia, marker of lower activity). - L-arginine deficiency may also result from a catabolism increase via arginase activity increased. This ubiquitous enzyme, having 2 isoforms (Arg1 and Arg2), allows the synthesis of urea and ornithine from L-arginine. An increase in arginase activity would decrease the available reserves of L-arginine for NO synthesis. The objectives of this work is to evaluate, in patients with severe sepsis or septic shock, the prognostic value of the plasma arginase activity and the plasma expression of 2 isoforms Arg1 and Arg2, their kinetics, and the link between activity / expression of arginase and enterocyte dysfunction.
