Cardiogenic shock is a condition of low cardiac output that represents the end of a progressive deterioration of cardiac function. The main cause is ischemic heart disease but there are several causes of non-ischemic nature including sepsis. Sepsis is characterized by a picture of organ dysfunction caused by an altered response of the body to an infection. Its most serious form is septic shock, defined as a picture of sepsis in which the underlying abnormalities in the cardiovascular system and cellular metabolism are such as to increase mortality. An organ failure correlates directly with the function of others and this interdependence is especially evident when a cardiovascular failure is established. 3 Cardiac dysfunction in sepsis can be defined as that of a syndrome characterized by low cardiac output not related to myocardial ischemia. The use of levosimendan in cardiogenic shock during sepsis was first described in a 2005 case report. Since then there have been small studies and other case reports that have shown improvements in right and left ventricular contractility, ventricular coupling, cardiopulmonary performance, global oxygen transport, renal and splanchnic perfusion when compared to dobutamine and placebo. Other beneficial effects of this drug have emerged, including an anti-inflammatory, antioxidant and antiapoptotic action with a possible protection from ischemia-reperfusion damage. The present study aims to evaluate the correct use of levosimendan, after the occurrence of cardiogenic shock on a low cardiac index has been ascertained, with the aim of weaning from inotropic drugs in infusion.
A randomized, prospective study comparing ProvayBlue® to standard care with multiple sympathomimetic vasopressors.
Septic syndromes are a major although largely under-recognized health care problem and represent the first cause of mortality in intensive care units (ICU). While it has long been known that sepsis deeply perturbs immune homeostasis by inducing a tremendous systemic inflammatory response, novel findings indicate that sepsis indeed initiates a more complex immune response that varies over time, with the concomitant occurrence of both pro- and anti-inflammatory mechanisms. As a resultant, after a short pro-inflammatory phase, septic patients enter a stage of protracted immunosuppression. This is illustrated in those patients by reactivation of dormant viruses (cytomegalovirus (CMV) or Herpes Simplex Virus (HSV)) or infections due to pathogens, including fungi, which are normally pathogenic solely in immunocompromised hosts. These alterations might be directly responsible for worsening outcome in patients who survived initial resuscitation as nearly all immune functions are deeply compromised. New promising therapeutic strategies are currently emerging from those recent findings such as adjunctive immunostimulation for the most immunosuppressed patients. The prerequisite for immunostimulation administration (Interferon gama (IFNg), Granulocyte Macrophage Colony Stimulating Factor (GM-CSF), interleukin 7 (IL-7)) however relies on clinicians' capacity to identify patients who could benefit the most from these immunoadjuvant therapies, as there is no clinical sign of immune dysfunctions. In this context, the main objectives of IMMUNOSEPSIS 4 study are: 1. to identify the best biomarkers for sepsis-induced immunosuppression 2. to evaluate ex vivo candidate treatments which could rejuvenate immune functions after septic shock
The incidence of sepsis (severe infection) has increased over the last four decades. Severe sepsis and septic shock are among the leading causes of death for patients admitted to critical care units with mortality ranging from 20-70% depending on totality of organ dysfunction. Outside of antibiotics and good bedside care, little has changed in the management of this life-threatening problem. Therapeutic plasma exchange (TPE) involves the separation of plasma from whole blood. The removed plasma is 'exchanged or replaced' with either IV fluids, albumin, blood products or a combination thereof. The primary objective of this study is to evaluate the safety of the TPE intervention protocol within 24 hours of study criteria being met. TPE is now a well-established program at the South Health Campus for neuro-muscular disorders. Since starting in May 2018, the investigators have performed over 150 runs making the SHC ICU one of the most experienced centers in Canada.
Septic shock is a major health problem, with several million cases annually worldwide and a mortality approaching 45%. Tachycardia is associated with excess mortality during septic shock. This pejorative effect could be related to the increase in cardiac metabolic demand, impaired cardiac diastolic function, and/or poorer tolerance of administered exogenous catecholamines. Recent studies suggest that controlling the heart rate with the use of beta blockers has beneficial effects on the morbidity and mortality of septic shock. However, the negative effects of beta-blockers on cardiac contractility and blood pressure complicate their use during septic shock, particularly because about one-half of patients exhibit a septic-associated systolic dysfunction, which often requires the use of inotropes. Ivabradine is a selective inhibitor of If channels in the sinoatrial node. It is a pure bradycardic agent with no deleterious effect on other aspects of cardiac function (contractility, conduction and repolarization) nor on blood pressure. Ivabradine can therefore alleviate sinus tachycardia without negative inotropic effects nor hypotension. Moreover, the improvement in diastolic function (ventricular filling) with ivabradine may increase stroke volume, even in case of severe impairment of systolic function. Controlling sinus tachycardia with ivabradine during septic shock would allow reducing cardiac metabolic demand (and potentially associated ischemic events) and improving the chronotropic tolerance of exogenous catecholamines. The effectiveness of ivabradine in controlling the heart rate was demonstrated in various clinical settings such as coronary artery disease, chronic heart failure and cardiogenic shock. Encouraging preliminary data are reported in critically ill patients.
This prospective randomized single center study investigates to what extent the removal of elevated cytokine levels by hemoadsorption has a positive effect on the treatment of patients in septic shock by stabilizing the circulatory situation.
Machine learning is a powerful method to create clinical decision support (CDS) tools, when training labels reflect the desired alert behavior. In our Phase I work for this project, we developed HindSight, an encoding software that was designed to examine discharged patients' electronic health records (EHRs), identify clinicians' sepsis treatment decisions and patient outcomes, and pass those labeled outcomes and treatment decisions to an online algorithm for retraining of our machine-learning-based CDS tool for real-time sepsis alert notification, InSight. HindSight improved the performance of InSight sepsis alerts in retrospective work. In this study, we propose to assess the clinical utility of HindSight by conducting a multicenter prospective randomized controlled trial (RCT) for more accurate sepsis alerts.
Sepsis is life-threatening organ dysfunction caused by a dysregulated host response to infection. It is the most expensive healthcare condition to treat in United States and has a mortality rate of nearly 30%. It is widely known that exaggerated inflammation and imbalance between sympathetic and parasympathetic arms of the autonomic nervous system (ANS) contribute to progression and adverse outcomes in sepsis. The role of unchecked inflammation and unregulated ANS as a potential treatment target is an important gap in our knowledge that should be explored. Cholinergic anti-inflammatory pathway (CAP) is an intricate network where the ANS senses inflammation by vagus nerve afferents and tries to regulate it by vagus nerve efferents to the reticuloendothelial system. The central hypothesis of this pilot clinical trial is that transcutaneous vagus nerve stimulation (TVNS) at tragus of the external ear can activate the CAP to suppress inflammation and improve autonomic imbalance as measured by inflammatory cytokine levels and heart rate variability (HRV) analysis. The investigators plan to randomize patients with septic shock into active and sham stimulation groups and study the effects of vagal stimulation on inflammatory cytokines, HRV and a clinical severity score of sepsis. Both groups will continue to receive the standard of care treatment for sepsis irrespective of group assignments. The investigators hypothesize that 4 hours of TVNS will suppress inflammatory markers and improve the balance between sympathetic and parasympathetic arms of ANS as measured by HRV, resulting in improved Sequential Organ Failure Assessment Score (SOFA). The preliminary data generated from this pilot study will lay the foundation for a larger clinical trial.
The pharmacokinetics of antimicrobials is profoundly modified in Intensive care unit (ICU) patients. To adapt the treatment, it is recommended to measure blood levels of antibiotics. Some antibiotics, such as amikacin, are easy to monitor, while for other molecules, such as piperacillin/tazobactam, the drug monitoring is more difficult to obtain. These two molecules have similar physicochemical characteristics (hydrophilicity) and therefore have closed pharmacokinetic properties. OPTIMA is a study aiming at criteria will be used to judge whether the pharmacokinetic (PK) parameters of amikacin are predictive of those of piperacillin and tazobactam.
