Cardiovascular Effects of Norepinephrine
Septic ShockPrevious studies of our team reported the improvement of myocardial contractility both on hemodynamic parameters (by transpulmonary thermodilution) and morphological (by transthoracic echocardiography: TTE), during the early phase of septic shock (during the first 4 hours management of septic shock). However, one can wonder about the effect of NAD on myocardial cardiac ouput and contractility beyond the early phase of septic shock, more precisely beyond the first 24 hours. Indeed, while it continues to act on the "stressed" blood volume and the diastolic left ventricular perfusion by increasing the diastolic arterial pressure (DAP), it has been reported in old studies that beyond the early phase, the sensitivity of the β1-adrenergic receptors is altered due to the phenomenon of internalization of these receptors, leading to a reduction of the myocardial response to catecholamines. The investigators can then wonder whether norepinephrine still exerts a positive effect on myocardial contractility via the increase in DAP, despite an alteration of the β1-adrenergic pathway. To answer this question, the investigators proposed to evaluate the effects of norepinephrine by TTE on cardiac contractility after the initial phase.
Effectiveness of Anisodamine Hydrobromide Combined With Heparin for the Treatment of Critically...
Septic ShockThe study aimed to investigate the effectiveness of anisodamine hydrobromide combined with heparin in the treatment of septic shock, in the hope that the therapy will provide alternatives to the treatment of septic shock.
Safety and Feasibility of Metformin for Sepsis Induced AKI
SepsisSeptic Shock2 moreAcute kidney injury (AKI) is an independent risk factor for death that affects 10-15% of hospitalized patients and more than 50% of patients admitted to the intensive care unit. Sepsis is the most frequent cause of AKI, affecting 48 million people worldwide every year, and accounting for approximately 11 million of annual global deaths. Despite these figures, there are no known therapies to prevent or reverse septic AKI; hence this study aims to establish the safety and feasibility of the implementation of metformin in the treatment of AKI in patients with sepsis. This study is the first critical step to inform the design of a future, full-scale efficacy randomized clinical trial.

Umbilical Mesenchymal Stromal Cells as Cellular Immunotherapy for Septic Shock
Septic ShockSepsis5 moreSeptic 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 (MSCs) 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 MSCs in patients with septic shock. The Cellular Immunotherapy for Septic Shock Phase I (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 (UC-CISS II) at several Canadian academic centres which will evaluate intermediate measures of clinical efficacy (primary outcome), as well as biomarkers, safety, clinical outcome measures, and a health economic analysis (secondary outcomes).

Iron Metabolism Disorders in Patients With Sepsis or Septic Shock.
Iron-deficiencyIron Deficiency Anemia3 moreAnemia is a common health problem. Depending on a geographical region, anemia affects even 50% of population. Among patients admitted to the intensive care unit (ICU) anemia may affect as much as 66% of patients. Moreover, many patients develop anemia during the ICU stay. In general population the most common cause of anemia is iron deficiency (ID). The investigators lack information on the incidence of ID and anemia of inflammation (AI) with absolute ID (mixed type of anemia: AI + IDA) or functional ID (AI) in patients with sepsis or septic shock hospitalised in the ICU. Therefore, the aim of the study is to improve diagnosis of iron deficiency (ID) and anemia of inflammation (AI) with absolute ID (AI + IDA) or functional ID (AI) in patients with sepsis or septic shock. ID have negative effects on the body and is associated with impaired production of proteins responsible for transport of oxygen in the blood (hemoglobin) and oxygen storage (myoglobin), and impaired immune function. Development of anemia is associated with well documented complications: organ hypoxia, myocardial infarction, stroke, infection. Replenishment of iron at this early stage may potentially prevent IDA. It is advantageous to replenish iron stores in order to avoid these complications, especially in patients with sepsis or septic shock. In IDA red blood cell transfusion is not recommended as it leads to other numerous complications. Therefore the patients presenting with laboratory results suggesting ID will receive divided doses od parenteral iron. Monitoring of iron replenishment will be based on a new laboratory parameter- reticulocyte hemoglobin equivalent.
