Filter by:Sepsis and severe malaria together contribute to an estimated 13 million deaths annually, a great burden of which is in low-income countries. Optimal fluid management is critical yet remains one of the most challenging clinical care elements as volume overload precipitates pulmonary edema and volume restriction may exacerbate acute kidney injury. These complications of sepsis and severe malaria significantly increase mortality, particularly in resource-limited settings lacking mechanical ventilation and renal replacement therapy. Point-of-care ultrasound and passive leg raise testing are two easily implementable, safe and non-invasive clinical bedside fluid assessment tools that could be applied towards developing a fluid management algorithm in low resource settings. Similarly, simple tissue perfusion measures can facilitate understanding of precise indications or contraindication to fluid and vasopressor therapy. However, the performance of these tools has yet to be confirmed in these settings. Accurate assessment of pulmonary tolerance and fluid responsive patients could aid to tailor vasopressor and fluid therapy to the patient condition and disease phase, thus preventing or detecting iatrogenic pulmonary edema and other pulmonary complications. As there is currently limited evidence supporting fluid management recommendations for severe malaria and sepsis in low-resource settings, the potential application of these management tools could optimize supportive therapy and improve outcomes in these populations. The main activity proposed is a prospective, observational study of patients with sepsis and severe malaria to describe the relationship between fluid therapy and vasopressor therapy against measures of tissue perfusion and pulmonary congestion in adult patients with severe malaria or severe sepsis. In addition, the study will assess the performance of simple bedside clinical tools assessing fluid responsiveness, pulmonary congestion and peripheral tissue perfusion. The data from this observational study will facilitate the preparation of a follow-up study to test a clinical algorithm to guide individualized fluid and vasopressor administration.
The purpose of this study is to confirm the clinical validity and the performance of the Monocyte Width Distribution (MDW) parameter to detect the development of sepsis in a prospective study of Emergency Department (ED) adults who have blood draw including Complete Blood Count with differential (CBC-DIFF) ordered upon presentation in a Spanish & French hospital and to verify cut-off for Tri-potassium ethylenediaminetetraacetic acid (K3EDTA).
The prevalence and mortality of sepsis in Turkey is not know at large. Turkish Society of Intensive Care Medicine, Sepsis Study Group conducted a multi-centre,point prevalence survey to determine the prevalence, causative micro-organisms and outcome of sepsis in Turkish ICUs.
Post extubation respiratory failure occur in 30% of extubated patients. More than 50% of them required reintubation. Noninvasive positive pressure ventilation (NIV) had been reported as an effective tool to prevent post extubation respiratory failure. Recently, high flow oxygen nasal cannula (HFNC) had been successfully used to prevent post extubation respiratory failure and prevent reintubation in comparable with NIV among post cardiothoracic surgery and high risk for reintubated patients. There was no information about HFNC versus NIV in prevention of reintubation among severe sepsis or septic shock patients.
In this prospective study, the ability of a machine learning algorithm to predict sepsis and influence clinical outcomes, will be investigated at Cabell Huntington Hospital (CHH).
IV fluid resuscitation has long been recognized to be an important treatment for patients with severe sepsis and septic shock. While under-resuscitation is known to increase morbidity and mortality, contemporary data suggests that overly aggressive fluid resuscitation may also be harmful. Currently, following an initial IVF resuscitation of 30 ml/kg, there is no standard of care and a lack of evidence to support a fluid restrictive or more liberal strategy. The investigators seek to determine if a fluid restrictive strategy reduces morbidity and mortality among patients with severe sepsis and septic shock.
Mitochondria are organelles (a specialized subunit of a cell) responsible for providing cells with energy. For reasons not yet understood, mitochondria will release their DNA into blood in response to cellular injury or cell death. With a simple blood draw, investigators can measure the amount of mitochondrial DNA in a patient's blood. The investigators' hypothesis, is that mitochondrial DNA can be used as a surrogate marker of cellular injury to predict patient outcomes. The investigators intend to test their hypothesis by measuring mitochondrial DNA in adult patients presenting to the Emergency Department with sepsis (a life-threatening condition due to an infection) and observing their hospital course.
Severe sepsis is a common condition with high mortality and morbidity. A previous meta-analysis has demonstrated the safety of glutamine supplementation with suggestion of mortality and morbidity benefits in critically ill patients. But there is lack of evidence to recommend the use of intravenous glutamine supplementation in this population group. A randomized controlled trial which is adequately powered will resolve this issue and can be included in future international nutrition guidelines for the critically ill. This pilot study is done prior to a proposed local multi-center study to investigate the effects of glutamine supplementation.
Nociceptin is a protein found in the body, with a number of functions in the central nervous system, blood vessels and the gut. There is evidence that it may have a role in controlling the immune response to infection, and may act as a link between the brain and immune system. In infection, or after surgery, there is an increase in nociceptin, and subjects greater elevations of nociceptin have a poorer outcome. There is evidence that cells of the immune system may produce nociceptin, although it is not yet known which cells are capable of producing it, and what "switches on" production. This study aims to determine 1. Which cells of the immune system can produce nociceptin 2. If there is a difference in the ability to produce nociceptin between healthy volunteers and patients with severe infections
Sepsis represents a serious public health issue characterized by a complex inflammatory response. In addition to their hemostatic role, platelets display inflammatory functions by secreting a variety of immunomodulatory factors and interacting with circulating immune cells. The investigators postulate that, in severe sepsis, platelets become activated and release amounts of different soluble inflammatory molecules that contribute to sepsis-associated inflammation. First, the investigators propose to assess whether severe sepsis impairs the ability of platelets to release soluble CD40L (sCD40L), an powerful platelet-derived immunomodulatory molecule, in ICU patients with S. aureus documented infection, ICU patients with documented infection involving other bacterial species, compared to ICU patients with inflammation of noninfectious origin and healthy blood donors. Then, the investigators wish to assess whether the bacterial species affects the release of platelet sCD40L and by an extensive screening of platelet soluble factors, the investigators propose to set up profiles of inflammatory molecules associated with the type of infection. Finally, the investigators will analyze platelets' activation state and their association with circulating immune, according to the type of infection. Therefore, this project is expected to assess to which extent the platelet inflammatory function is super-activated in severe sepsis and to identify new platelet-related biomarkers of sepsis.
