Brief Summary:
The aim of the current study is to evaluate suPAR - guided medical intervention, consisting of early antibiotic administration at the emergency room for presumed infection and sepsis and evaluate the impact of this intervention to the patients' final outcome. Since the traditionally used biomarkers (PCT, CRP) and scores (SOFA score) for early recognition of severity of infection fail to achieve maximum accuracy in all cases, suPAR levels are assessed as a probably better prognostic rule for early recognition of severe infections. The primary study endpoint will be the comparative efficacy of the early suPAR-guided administration of antibiotics versus standard practice on 28-day mortality.
Detailed Description:
Sepsis is among the leading causes of death worldwide. It is well-perceived that early recognition of sepsis is the mainstay of treatment. Recently it has been proposed that the quick sequential organ fialure assessment (qSOFA) score can be used as a screening tool in the emergency department (ED) to triage patients with high-risk of death; patients scoring positive at least two of the three signs of qSOFA are at a high-risk for death. However, this is challenged since it may be the case that the risk of death is high even among patients with only one sign of qSOFA.
Soluble urokinase plasminogen activator receptor (suPAR), the soluble form of the membrane bound receptor (uPAR), is a recently known glycoprotein involved in inflammation. uPAR is expressed on various immune cells (neutrophils, lymphocytes, monocytes, macrophages) and is cleaved from their surface after an inflammatory stimuli to enhance chemotaxis and cell migration. Increased suPAR blood levels mirror the degree of activation of the immune system by different antigenic stimuli including diverse neoplastic and infectious agents and other inflammation-mediated diseases. SuPAR levels generally correlate to the severity of the disease.
It has been shown that suPAR blood levels have low diagnostic value (cannot discriminate between bacterial, viral or parasitic infection, Gram (+) or Gram (-) bacteraemia. However, they present superior prognostic value as compared with single parameters of inflammation and organ dysfunction (like C-reactive protein (CRP) and procalcitonin (PCT) in critically ill patients, and suPAR's prognostic value of death is even more enhanced when combined to other biomarkers and physiological scores (e.g. Acute Physiology and Chronic Health Evaluation-APACHE II).
Why choose suPAR as biomarker at emergency basis? Because, in contrast to many pro-inflammatory cytokines, suPAR exhibits favorable properties due to its high stability in serum samples and limited circadian changes in plasma concentrations. It also constitutes a serum/plasma biomarker that is easily performed on-site and provides information within one hour after sampling21, 22.
Unpublished data of the Hellenic Sepsis Study Group (HSSG) suggest that among patients with at least one sign of the qSOFA score, those with suPAR greater than 12 ng/ml are at a substantial risk for death with mortality exceeding 30%. To this end, patients with suspicion for an infection and with qSOFA 1 and suPAR greater than 12 ng/ml constitute a group of patients requiring early intervention.
The aim of the current study is to evaluate suPAR - guided medical intervention, consisting of early antibiotics' administration at the emergency room for presumed infection and sepsis and evaluate the impact of this intervention to the patients' final outcome.
