BACKGROUND/OBJECTIVE: Prothymosin alpha (proTα) is a ubiquitous polypeptide first isolated by Haritos in 1984, whose role still remains partly elusive. We know that proTα acts both, intracellularly, as an anti-apoptotic and proliferation mediator, and extracellularly, as a biologic response modifier mediating immune responses similarly to molecules termed "alarmins". Our research team pioneered the elucidation of the mechanisms underlying the observed activities of proTα. RESULTS: We were the first to demonstrate that proTα levels increase during normal and abnormal cell proliferation...

A nanochannel-based electrochemical biosensor has been demonstrated for rapid and multiplexed detection of a panel of three biomarkers associated with rapid detection of sepsis. The label-free biosensor detected procalcitonin (PCT), lipoteichoic acid (LTA), and lipopolysaccharide (LPS) from human whole blood. The biosensor comprises a nanoporous nylon membrane integrated onto a microelectrode sensor platform for nanoconfinement effects. Charge perturbations due to biomarker binding are recorded as impedance changes using electrochemical impedance spectroscopy...

Disseminated intravascular coagulation (DIC) is a major pathophysiological mechanism of sepsis and greatly increases the risk of death in septic patients. Disseminated intravascular coagulation is a complex physiological phenomenon that involves inappropriate activation of coagulation, inflammation, and endothelial processes. The purpose of this study was to analyze the levels of inflammatory cytokines in the plasma of patients with DIC in order to compare the measured levels with those from healthy individuals, draw correlations, and provide a basis for further biomarker panel development...

OBJECTIVE: Methods containing only clinical information fail to meet the needs of prediction of acute lung injury (ALI) because of the relatively low positive predictive value. This study aimed to investigate the feasibility of using biomarkers as predictors of ALI in populations with severe sepsis/septic shock and to explore difference among biomarkers after adjustment for potential confounders. METHODS: Serum specimens were collected from patients with severe sepsis/septic shock (n = 172) presented to the emergency department...

Sepsis remains a challenging clinical problem requiring prompt diagnosis and optimal clinical management if the continuing high mortality is to be contained. In this brief review I consider four specific questions that are the subject of ongoing controversy. First, whether the new 'Sepsis-3' definitions will be helpful, in particular in improving diagnosis, or whether the rapid move towards precision medicine will make the definition redundant. Second, should we routinely use combinations of antibiotics for the empiric treatment of sepsis...

The aim of the study was to evaluate the usefulness of presepsin as a diagnostic marker of sepsis in intensive care unit (ICU) patients. Presepsin was measured by a rapid method based on a chemiluminescent enzyme immunoassay (PATHFAST). The clinical usefulness of presepsin to diagnose sepsis and septic shock was studied and compared with procalcitonin, C-reactive protein and total leucocytic count. This study was conducted on 53 individuals divided into 3 groups. Group I included 28 adult ICU patients with at least two diagnostic criteria for systemic inflammatory response syndrome (SIRS) as patient group, Group IIa 15 patients admitted to ICU for any medical cause but with no evidence of infection were enrolled as patient control group and further 10 apparently healthy subjects as healthy control group...

Presepsin has recently been described as biomarker of sepsis. The aim of this study was to investigate the diagnostic accuracy of presepsin in diagnosing neonatal sepsis and discriminating sepsis from non-infectious systemic inflammatory response syndrome (SIRS). The study included 70 full term neonates divided into three groups: 1) Sepsis group (22 patients with clinically suspected sepsis and positive blood cultures) 2) Non-infectious SIRS group (28 patients with clinically suspected sepsis and persistently negative blood cultures) 3) Control group (20 healthy neonates without any clinical signs of infection)...

Septicemia is a growing problem within the United States (US), which increases mortality and the cost of care. Procalcitonin is a pro-inflammatory marker that could be useful in the diagnosis of infection. In the past, procalcitonin levels have been evaluated to diagnose sepsis or guide antibiotic therapy, but it was not determined if it would differentiate between sepsis and other causes of inflammation. Studies reviewed here showed procalcitonin to be a useful biomarker as an indication of bacterial infection...

Sepsis causes multiple organs failures and eventually death. Changes in blood constituents due to sepsis lead to alterations in hemorheological properties, and cell adhesiveness. In this study, a new microfluidic system is proposed to measure temporal variations in biophysical properties of blood after injecting lipopolysaccharide (LPS) into a rat extracorporeal model under ex vivo condition. To measure blood viscosity, the interfacial line between blood and a reference fluid is formed in a Y-shaped channel...

BACKGROUND: Pneumonia is among the most common acute complications after stroke and is associated with poor long-term outcome. Biomarkers may help identifying stroke patients at high risk for developing stroke-associated pneumonia (SAP) and to guide early treatment. AIMS: This trial investigated whether procalcitonin (PCT) ultrasensitive (PCTus)-guided antibiotic treatment of SAP can improve functional outcome after stroke. METHODS: In this international, multicenter, randomized, controlled clinical trial with blinded assessment of outcomes, patients with severe ischemic stroke in the middle cerebral artery territory were randomly assigned within 40 h after symptom onset to PCTus-based antibiotic therapy guidance in addition to stroke unit care or standard stroke unit care alone...

PURPOSE: Intensive care unit (ICU)-acquired infections (IAI) result in increased hospital and ICU stay, costs and mortality. To date, no biomarker has shown sufficient evidence and ease of application in clinical routine for the identification of patients at risk of IAI. We evaluated the association of the systemic mRNA expression of two host response biomarkers, CD74 and IL10, with IAI occurrence in a large cohort of ICU patients. METHODS: ICU patients were prospectively enrolled in a multicenter cohort study...

Zinc is an essential trace element for both pathogens and hosts. Hypozincemia is a well known phenomenon in sepsis patients and represents the innate immune systems attempt to deprive pathogens of zinc. However little is known about course, restitution and prognostic value of serum zinc levels in sepsis patients. We performed a prospective observational single-center study set in a tertiary care university hospital intensive care unit. Serum zinc levels were singularly measured of healthy controls and sequentially of surgical sepsis patients and surgical patients over a 8-day period...
