Active clinical trials for "Shock, Septic"

The objective of this project is to determine if in patients admitted to the hospital with septic shock (population), does treatment with a bundle including hydrocortisone, thiamine, and ascorbic acid improve in-hospital or 28-day mortality (primary outcomes) or surrogate markers of illness severity including: (1) ICU or hospital length-of-stay, (2) duration of invasive mechanical ventilation, (3) duration of vasopressor administration, (4) incidence and severity of ICU delirium, and (5) illness severity (secondary outcomes).

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).

Septic shock is a devastating condition often observed in ICU. It is characterized by pro-inflammatory and immune responses, organ failures, high incidence of AKI and lethality. Fluid resuscitation is pivotal as supportive therapy. At present, there are no effective therapies to improve survival of such clinical condition, often characterized by a mortality as high as 40% during the first 90 days from diagnosis. This project proposes a large 2-by-2 factorial randomized clinical trial testing the efficacy of albumin and the low- chloride balanced crystalloid solutions (either Ringer Lactate, Ringer Acetate, or Crystalsol - BAL) in septic shock. The investigators have recently concluded a multicenter, randomized trial, the ALBIOS trial, in which, in a post-hoc analysis, albumin, in addition to crystalloids, reduced 90-day mortality in patients with septic shock, as compared to crystalloids alone (Caironi P et al, 2014). Crystalloids with supra-physiological chloride content may deteriorate renal perfusion, increasing the risk of acute kidney injury (AKI) and mortality.

Septic shock is associated with substantial burden in terms of both mortality and morbidity for survivors of this illness. Pre-clinical sepsis studies suggest that mesenchymal stem (stromal) cells may modulate inflammation, enhance pathogen clearance and tissue repair and reduce death. Our team has completed a Phase I dose escalation and safety clinical trial that evaluated mesenchymal stem cells (MSCs) in patients with septic shock. The Cellular Immunotherapy for Septic Shock (CISS) trial established that MSCs appear safe and that a randomized controlled trial (RCT) is feasible. Based on these data, the investigators have planned a phase II RCT (CISS2) at several Canadian academic centres which will evaluate safety, signals for clinical efficacy, and continue to examine potential mechanisms of action and biological effects of MSCs in septic shock.

Proprotein convertase subtilisin kexin 9 (PCSK9) inhibitors increase LDL receptors by decreasing its degradation. In sepsis the pathogenic substances, endotoxin, lipoteichoic acid, phospholipomannan are the main cause of the ongoing inflammation that causes the severe damage and outcome. these substances are removed from the blood by the LDL receptors. By administering PCSK9 inhibitors to patients with sepsis/septic shock this inflammatory response can be stopped and by doing so improve the patients outcome.

The investigators preliminary study showed that dexmedetomidine might improve microcirculation in septic shock patients. To test this effect, the investigators will conduct double-blinded study.

The investigators will conduct a prospective, single-center, randomized, double-blinded, controlled study to investigate the effect of early goal directed sedation on microcirculation in early septic shock patients.

The aim of this study is to investigate the effects milrinon and levosimandan on n heart function in septic cardiomyopathy and how norepinephrine affects the left and right ventricular function in patients with septick shock using pulmonary artery catheter, conventional and strain echocardiography.

Early goal directed therapy (EGDT) is an effective treatment for patients with septic shock, which is widely used in clinic. Fluid resuscitation can significantly reduce the mortality of patients with septic shock and improve the prognosis of patients with EGDT. However, in recent years, the standard of EGDT to determine the existence of the target of septic shock. Some studies have shown that there may be a manifestation of the deficiency of kidney and liver and other organs such as kidney, liver and other organs in the recovery of EGDT. Therefore, this experiment is to explore the brain perfusion and metabolism of the EGDT when the target is reached.The aim of this study was to investigate the effects of EGDT as a guide to the cerebral perfusion and metabolism in order to provide clinical evidence for the treatment of fluid resuscitation in patients with septic shock.

Reducing tissue hypoxia is the ultimate goal of severe sepsis and septic shock therapy.Venoarterial PCO2 difference /arteriovenous O2 content difference ratio (△PCO2/Ca-vO2) is considered to be a good indicator of global anaerobic metabolism.The purpose of this study was to compare the efficacy of △PCO2/Ca-vO2 and central venous oxygen saturation (ScvO2) in the treatment of severe sepsis and septic shock.
