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.
Severe sepsis leads a high morbidity and mortality by causing organ damage at distance. The treatment relies on early antibiotic therapy and hemodynamic resuscitation. Hypothesis: high flow nasal cannula (HFNC) could reduce work of breathing and improve the outcome of patients with severe sepsis and peripheral perfusion. Objective: the aim of this study is to evaluate the efficacy of HFNC for improving sixty-day survival in patients with severe sepsis. Design: multicenter parallel-group randomized clinical trial. Method: 592 adult patients with a diagnosis of severe sepsis in the first 12 hours of admission in the Emergency Room will be randomly assigned to an experimental or control group. In the experimental group, HFNC will be administered until the resolution of sepsis or until required mechanical ventilation, either invasive or non-invasive. In the Control group, conventional oxygen will be administered, if required. Sixty-day survival will be the primary outcome. The study is powered to demonstrate an improvement in survival from 70% in control group up to 80% in the HFNC group. The secondary outcomes will be reducing the need for vital support (mechanical ventilation, dialysis, vasoactive drugs) and physiological (acidosis, clearance of lactate, SvO2 and SOFA). Statistical analysis: Kaplan-Meier curves and Cox proportional hazard models will be calculated for all-cause sixty-day survival. If the results are conclusive, they will have immediate application in medical practice.
Sepsis remains a major cause of death in developed countries. A better understanding of the mechanisms involved in the regulation of inflammatory and immune response of patients with severe sepsis is an important step that could open the way for new therapeutic approaches.
Purpose/Objectives: Severe sepsis and septic shock are a common cause of new onset atrial fibrillation (NOAF) in the intensive care unit. Development of NOAF in this setting can prolong length of stay and increase mortality. Amiodarone is the most commonly used agent used in this setting to control rate and rhythm. However, limited data exist detailing appropriate dosing in this setting. The primary objective of this study is to evaluate two amiodarone dosing strategies, a full loading dose versus a partial loading dose, in patients with new-onset atrial fibrillation (AF) due to severe sepsis or septic shock to assess the mean heart rate every 6 hours after initiation of amiodarone infusion to day 7 or death. Research Design/Plan: Consecutive patients admitted to the medical or cardiac intensive care unit at University Hospital with NOAF in the setting of severe sepsis or septic shock will be screened for study inclusion. Data will be collected and stored using Microsoft Excel or Access and analyzed with JMP 12.0 and SPSS. Methods: Patients aged 18 years or older who develop new-onset atrial fibrillation in the setting of severe sepsis or septic shock and in whom the medical team deems appropriate to initiate amiodarone therapy in will be considered for study inclusion. Patients will receive intravenous (IV) and oral (PO) amiodarone, as per the standard of care. Patients will be randomized to a certain quantitative loading dose strategy; either a full loading dose (≥ 5g IV or ≥10g PO +/- 20%) or a partial loading dose (<4g IV or < 8g PO). Clinical Relevance: With intensive care unit length of stay (ICU LOS) and mortality being twice as high in NOAF with sepsis as compared to septic patients without NOAF, the investigators ultimately aim to identify a management strategy that may minimize this morbidity and mortality while also minimizing exposure to a drug that may cause serious adverse effects.
The purpose of this study is to determine whether BMS-936559 is safe and has the desired pharmacologic activity in patients who have severe sepsis.
To validate the use of the Heparin Binding Protein (HBP) concentration to assist in the evaluation of patients admitting to the emergency department with suspected infection.
Despite early goal-directed maintenance of normal macrocirculation, the reduction of 60-day mortality of patients with severe sepsis and septic shock remained unsatisfied (56.9% to 44.3%). One of the major causes of high mortality is microcirculatory dysfunction. Delayed diagnosis and treatment of microcirculatory dysfunction may cause tissue hypoperfusion and resulted in multiple organ dysfunction and death. Dexmedetomidine is a highly selective α2-adrenoreceptor agonist which exhibits sedative and analgesic effects. Recent studies suggest that dexmedetomidine also has anti-coagulation and anti-inflammatory effects, and it can reduce the mortality of endotoxemic rats and patients with severe sepsis. The investigators will conduct two animal studies and one clinical trial to investigate the effect of dexmedetomidine on microcirculatory dysfunction and organ injury in rat with endotoxemia and patients with severe sepsis and septic shock. Sixty patients with severe sepsis and septic shock will be enrolled and randomized to control group or dexmedetomidine group. In the control group, the patients will be treated according to the clinical practice guideline. If sedation is required, non-dexmedetomidine sedative agents will be used. In the dexmedetomidine group, the patients will be treated according to the clinical practice guideline, and they will also receive continuous infusion of dexmedetomidine (infusion rate ranged from 0.1 to 0.7 mcg/kg/h) for 24 hours as needed. The sublingual microcirculation, serum level of Endocan, NGAL(Neutrophil Gelatinase-Associated Lipocalin), and BNP(B-type natriuretic peptide) will be examined at preset time points up to 24 hours. The vital signs, hemodynamic parameters, and survival of 28-day and 90-day will be recorded and analyzed.
Endotoxin is the major mediator of gram-negative bacteria which cause the systemic inflammation and result in microcirculatory dysfunction, and it leads to multiple organ dysfunction and death in patients with severe sepsis and septic shock. The goal of this study is to measure the endotoxin activity of patients with severe sepsis and septic shock at certain time points, and furthermore, to compare the difference of endotoxin activity among different pathogens, infection source, and antibiotics. The study will enroll severe sepsis and septic shock patients. The endotoxin activity will be measured at certain time points according to the protocol.
The epidemiology of this study aims and outcome of patients with septic shock in the intensive care unit (or versatile) of the North-East region in france as well as the modalities of care.
Rationale : Electric muscle stimulation reduced critical-illness related weakness in patients with severe sepsis and septic shock. But optimal protocol of the stimulation in unknown. Hypothesis: Focal muscle contraction may improved the muscle power and have systemic anti-inflammatory via cytokine secretion . The difference of electricity used in upper limb or lower limb stimulation may lead to different effect. Study design: Stratified randomized parallel control study, comparing Biceps, Quadriceps electric muscle stimulation vs. non-stimulation group. Participant: adult patients with severe sepsis and acute respiratory failure requiring mechanical ventilation. Intervention: daily stimulation of bilateral Biceps or Quadriceps by programmed electric devices 32 minutes, 5 days/week Outcome: 1. Primary outcome: Ventilator-dependent days 2. Secondary outcome: change of hand drip muscle power/interleukin-1b/interleukin-6/interleukin-8/TNF-alpha
