Predict Sepsis; the Predictive Value of Bedside Measures in the Ambulance

SepsisSepsis Syndrome2 more

Sepsis is a condition with a high mortality. Septic patients are frequently difficult to identify because of their non-specific presentations. There is also a low sensitivity of clinical judgment among health care personnel, and of existing screening tools, which are in turn typically based on vital parameters. Despite prior research, no unique sepsis biomarker has been identified so far. There is a need for new strategies to identify sepsis which do not rely on vital parameters and traditional laboratory blood tests alone. The hypothesis of the investigators is that a combination of clinical variables measurable in the ambulance can be used to predict sepsis. The aim of the current study is to determine the predictive value of keywords related to symptom presentation, vital parameters and point-of-care (POC) blood tests, alone and in combination, with respect to the outcome sepsis. The study is performed in the Stockholm ambulance setting from April 2017. A total of 956 adult non-trauma patients will be included.

The Efficacy of High-flow Nasal Cannula Oxygen Therapy in Sepsis Patients

High Flow Nasal CannulaSepsis Syndrome

Sepsis is a heterogeneous syndrome that is caused by the host imbalance immune response. At 1991, the American College of Chest Physicians/Society of Critical Care Medicine Consensus Conference developed a definition of sepsis. After more than 20 years, it was gradually developed in 2016 to the third edition of the guidelines for sepsis(Sepsis-3). Sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. According to the National Health Insurance claims database of Taiwan, The incidence rate was 772.1/100,000 persons in 2012. From 2002 to 2012, the incidence of sepsis increased by 18.7%. The mortality of severe sepsis was 17.9%. However, has increased to 33% when developed to septic shock. Even in foreign studies, the intensive care unit mortality rate can reach 40%. Although sepsis was defined in 1991, after these years, the treatment of sepsis is still a goal that must be worked hard. According to Sepsis-3, must first use the qSOFA (quick Sepsis Related Organ Failure Assessment) to assess whether the patient's blood pressure, respiratory rate, and state of consciousness meet more than two criteria, which is sepsis. If the SOFA score (Sequential Organ Failure Assessment) is further evaluated, with at least two of the following symptoms, including poor oxygenation in the lungs, hypotension or use of a vasopressor, thrombocytopenia, conscious change (Glasgow Coma Scale), bilirubin increase and creatinine rise or oligouria. If the patient must use a vasopressor to maintain a mean arterial pressure (MAP) of 65 mmHg and serum lactate more than 18 mg/dL, it is Septic shock. In clinical assessment, qSOFA (rapid sepsis-associated organ failure assessment) can also be used to assess blood pressure, respiratory rate, and state of consciousness to confirmed sepsis. According to the above assessment conditions, patients with sepsis are highly prone to respiratory failure during the disease process. In recent trials, about 40% to 85% of patients with sepsis must be need endotracheal intubation, showing the high intubation rate. Patients after intubation may cause lung injury due to improper ventilator settings (Ventilator-induced lung injury, VILI). And 10% to 25% will be combined with pneumonia caused by the ventilator (ventilator-associated pneumonia, VAP). Mortality can reach 20% to 33%. So if we can reduce septic patient's intubation rate then we can reduce the complication caused by the ventilator. A high flow nasal cannula (HFNC) is a relatively new device for respiratory support. Patients received high-flow conditioned oxygen therapy through a nasal prong. A number of physiological effects have been described with HFNC: pharyngeal dead space washout, a positive expiratory pressure to reduce work of breathing, improve breathing synchronization. These benefits can reduce the intubation rate. The benefit of the HFNC in septic patients is not very clear. By this prospective study to investigate the septic patients who have been admitted to the intensive care unit. The study method is to ask the patient whether they agree to participate in the trial after the patient is transferred to the intensive care unit. The patient will randomly assign the subjects to the general oxygen therapy and the HFNC group after signing the subject consent form. This study aimed to determine whether high-flow oxygen therapy immediately would reduce the need for intubation compared with standard oxygen therapy in sepsis patients.

Towards a High-fat Feeding Intervention Study: Identification of Markers for Inflammation and Organ...

Systemic Inflammatory Response SyndromeSepsis

Patients undergoing major surgery, trauma or burns are prone to develop an exacerbated inflammatory response, which is potentially lethal to the individual. Recently, the researchers' group showed in a rodent model of hemorrhagic shock that high-fat feeding administered before shock attenuates inflammation and reduces intestinal and hepatic damage. In the mechanism that underlies this protective effect, the release of cholecystokinin in gut wall and activation of efferent vagus bundles are crucial events. Before investigating the effect of high-fat nutrition in clinical setting, suitable markers of inflammation and organ damage need to be selected. In this study, blood will be collected in patients undergoing different types of operations. Consequently several markers for inflammation and organ damage will be determined. Hence, suitable parameters for a future high-fat intervention study will be selected.

Prediction of Inflammatory Response and Hypotensive Syndrome After Cardiac Surgery by Preoperative...

Systemic Inflammatory Response Syndrome (SIRS)Postoperative Vasodilation Syndrome3 more

The purpose of this study is to find a preoperative biomarker before cardiac surgery with cardiopulmonary bypass related to severe postoperative inflammatory response and circulatory complications. The investigators hypothesize that an increase of the preoperative stimulation of vasopressinergic system (in response to acute or chronic conditions) could lead to a microcirculatory dysfunction and favor the occurrence of vasodilatation during and after CPB and increase the symptoms of an inflammatory response after CPB. By defining a high risk population, a targeted strategy of monitoring and early or preventive treatment could improve postoperative prognosis.

Mitochondrial DNA as a Biomarker of Sepsis Severity

Sepsis SyndromeSepsis3 more

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.

Procalcitonin (PCT) as a Diagnostic Marker of Bacterial Infection in the Patients Admitted for Fever...

Systemic Inflammatory Response SyndromeFever

Levels of PCT (a marker of bacterial infection) are highest during sepsis: in fact, PCT is normally produced by the C cells in the thyroid gland. PCT was initially studied by Assicot1 for distinguishing between bacterial meningitis and viral meningitis. The CALC-I gene codes for PCT. In the absence of infection, the extrathyroid mRNA expression of the CALC-I gene is repressed, and expression is restricted to neuroendocrine thyroid and pulmonary cells. Infection induces the ubiquitous expression of the CALC-I gene. PCT is not transformed into calcitonin in parenchymatous tissues. In a context of sepsis, the whole body acts as a neuroendocrine gland. Sepsis upregulates PCT mRNA expression much more than that of other cytokines. PCT is used in critical care departments as a diagnostic marker, a guide to treatment (antibiotics are withdrawn if the level falls) and a prognostic marker. There are few data on the diagnostic use of PCT in an internal medicine department. The available studies yielded contradictory results and only one prospective study has been performed . The objective was to study PCT in non-infectious, inflammatory pathologies and to establish whether PCT could distinguish infections from other inflammatory pathologies in patients in an internal medicine department. In a ROC curve analysis, a PCT threshold of 0.35 µmol/l gave the greatest specificity (88%) and sensitivity (72%). Other studies have been performed but featured small sample sizes and a retrospective design. Of the various studies performed in internal medicine departments, none included patients presenting with a suspected bacterial infection (according to the clinician's interpretation) and lacking information on their bacterial status. In fact, these diagnoses are a core component of hospitalisation in internal medicine departments for fever or inflammatory syndrome. The investigators intend to include all patients, including those lacking information on their microbiological status).

Endothelial Microparticles as a Biomarker for Diagnosis and Prognosis in Early Sepsis

Systemic Inflammatory Response Syndrome

Sepsis is a major global health problem, leading to substantial morbidity and mortality despite medical care. The initial diagnosis of sepsis is a clinical challenge, as it is based on nonspecific systemic criteria. Excessive endothelial activation is a cardinal feature of sepsis and contributes to microvascular leak, edema, circulatory shock and organ failure. Activated endothelial cells shed endothelial microparticles (EMPs) which can be measured in plasma and are found at low levels in healthy subjects. Elevated EMPs have been reported in sepsis, but whether their effect is beneficial or deleterious is unclear. In this context, we hypothesize that circulating EMP levels can be assessed as a biomarker differentiating sepsis from non-sepsis critical illness. This may also suggest that EMP levels correlate with 30-day mortality. We propose to measure circulating EMPs at ICU admission in subjects with suspected sepsis. Final diagnoses will be adjudicated using standard criteria and 30-day mortality ascertained. Subjects determined not to have sepsis will serve as the control group. EMP levels will be correlated with diagnosis to ascertain the utility of EMP levels as a diagnostic biomarker for sepsis. For those subjects with proven sepsis, EMP levels will be correlated to 30-day mortality to assess EMP level as a prognostic marker in sepsis.
