Sepsis is a heterogeneous disease caused by an infection stimulus that triggers several complex local and systemic immuno-inflammatory reactions, which results in multiple organ dysfunction and significant morbidity and mortality. The diagnosis of sepsis is challenging because there is no gold standard for diagnosis. As a result, the clinical diagnosis of sepsis is ever changing to meet the clinical and research requirements. Moreover, although there are many novel biomarkers and screening tools for predicting the risk of sepsis, the diagnostic performance and effectiveness of these measures are less than satisfactory, and there is insufficient evidence to recommend clinical use of these new techniques...

Regardless of its etiology, once septic shock is established, survival rates drop by 7.6% for every hour antibiotic therapy is delayed. The early identification of the cause of infection and prognostic stratification of patients with sepsis are therefore important clinical priorities. Biomarkers are potentially valuable clinical tools in this context, but to date, no single biomarker has been shown to perform adequately. Hence, in an effort to discover novel diagnostic and prognostic markers in sepsis, new genomic approaches have been employed...

Plasma volume and red cell mass are key health markers used to monitor numerous disease states, such as heart failure, kidney disease or sepsis. Nevertheless, there is currently no practically applicable method to easily measure absolute plasma or red cell volumes in a clinical setting. Here, a novel marker for plasma volume and red cell mass was developed through analysis of the observed variability caused by plasma volume shifts in common biochemical measures, selected based on their propensity to present with low variations over time...

Sepsis-induced myocardial dysfunction represents a major cause of death in intensive care units. Dysregulated microRNAs (miR)-155 has been implicated in multiple cardiovascular diseases and miR-155 can be induced by lipopolysaccharide (LPS). However, the role of miR-155 in LPS-induced cardiac dysfunction is unclear. Septic cardiac dysfunction in mice was induced by intraperitoneal injection of LPS (5 mg/kg) and miR-155 was found to be significantly increased in heart challenged with LPS. Pharmacological inhibition of miR-155 using antagomiR improved cardiac function and suppressed cardiac apoptosis induced by LPS in mice as determined by echocardiography, terminal deoxynucleotidyl transferase nick-end labeling (TUNEL) assay, and Western blot for Bax and Bcl-2, while overexpression of miR-155 using agomiR had inverse effects...

As secondary complications remain a significant cause of morbidity and mortality amongst hospitalised trauma patients, the need to develop novel approaches by which to identify patients at risk of adverse outcome is becoming increasingly important. Centred on the idea that patients who experience "poor" outcome post trauma elicit a response to injury that is distinct from those who experience "good" outcome, tailored therapeutics is an emerging concept aimed at improving current treatment regimens by promoting patient-specific therapies...

BACKGROUND: Early onset sepsis (EOS) remains a major cause of mortality and morbidity in neonates, and traditional clinical markers effective for adults are less effective in these patients. This study aimed to assess the value of individual plasma biomarkers as well as biomarker combinations for predicting EOS in neonates. METHODS: This prospective study included 151 neonates with suspected EOS. Plasma levels of interleukin (IL)-27, IL-6, IL-8, tumor necrosis factor (TNF)-α, heat shock protein (HSP) 70, macrophage inflammatory protein (MIP)-1α, MIP-1β, granzyme B, and matrix metalloproteinase (MMP)-8 were measured through multiplex cytokine profiling and assessed along with C-reactive protein (CRP) and procalcitonin (PCT)...

BACKGROUND: Early onset sepsis (EOS) remains a major cause of morbidity and mortality in newborns; however, current diagnostic tools are inadequate. We evaluated the accuracy of a novel cytokine, interleukin (IL)-35, for the diagnosis of EOS in comparison with other infection markers. METHODS: One hundred fifty-seven neonates with suspected sepsis in the first 3days of life were enrolled in this perspective study. All enrolled patients were divided into infected group and unlikely infected group according to clinical data...

The triggering receptor expressed on myeloid cells (TREM)-1 is a member of the Ig-like immunoregulatory receptor family and a major amplifier of innate immune responses. TREM- 1 has been implicated in the development and perpetuation of a number of inflammatory disorders, and soluble TREM-1 levels are a clinically valuable diagnostic and prognostic biomarker in patients with sepsis and other types of acute and chronic inflammation-associated diseases, easily detectable in biological fluids. High TREM-1 expression in macrophages infiltrating human tumors and increased concentrations of soluble TREM-1 also correlate with aggressive tumor behavior and recurrence and are a relevant independent predictor of poor patient survival...

BACKGROUND: Community acquired pneumonia (CAP) is a high incidence disease resulting in about 260,000 hospital admissions per year in Germany, more than myocardial infarction or stroke. Worldwide, CAP is the most frequent infectious disease with high lethality ranging from 1.2 % in those 20-29 years old to over 10 % in patients older than 70 years, even in industrial nations. CAP poses numerous medical challenges, which the PROGRESS (Pneumonia Research Network on Genetic Resistance and Susceptibility for the Evolution of Severe Sepsis) network aims to tackle: Operationalization of disease severity throughout the course of disease, outcome prediction for hospitalized patients and prediction of transitions from uncomplicated CAP to severe CAP, and finally, to CAP with sepsis and organ failure as a life-threatening condition...

OBJECTIVE: The monitoring of septic shock induced immunosuppression has been proposed to identify patients that could benefit from specific immunoadjuvant therapies. Among potential biomarkers to monitor immunological status, functional testing remains the gold standard because it directly measures the capacity of a cell population to respond to an immune challenge. We investigated a new approach in intracellular staining for flow cytometry to measure TNF (iTNF) produced in vitro by monocytes in response to LPS...

Sepsis is defined as life-threatening organ dysfunction caused by dysregulated host responses to infection (Third International Consensus definition for Sepsis and septic shock). Despite decades of research, sepsis remains the leading cause of death in intensive care units. More than 40 clinical trials, most of which have targeted the sepsis-associated pro-inflammatory response, have failed. Thus, antibiotics and fluid resuscitation remain the mainstays of supportive care and there is intense need to discover and develop novel, targeted therapies to treat sepsis...

Sepsis is as life-threatening organ failure caused by a dysregulated host response to infection, with urgent onset, complex mechanism and high mortality. Its early diagnosis and treatment is particularly important. However, the sensitivity and specificity of current laboratory markers for the diagnosis of sepsis is not ideal. MicroRNAs represent a novel group of small RNA molecules that do not encode for proteins. MicroRNAs are synthesized in the cytoplasm and transferred to circulation primarily by micro-vesicles, and they are stable in circulation and can be rapidly detected...

Infections and sepsis are more common in cirrhotic than in the general population and constitute the commonest cause of sudden worsening and death. The diagnosis of systemic inflammatory syndrome and sepsis are challenging in cirrhotics due to an underlying a state of hyperdynamic circulation. Further, poor nutritional and bone marrow reserves lead to modest host immune response, the so called immunoparalysis state and the outcome of antibiotic therapy is suboptimal. In this review, a comprehensive description of current and emerging concepts in the pathogenesis and diagnosis of sepsis with importance to current and novel biomarkers for diagnosis of sepsis in cirrhosis is presented...

OBJECTIVE: The aim of this study was to describe current understanding of the local and systemic immune responses to surgery and their impact on clinical outcomes, predictive biomarkers, and potential treatment strategies. BACKGROUND: Patients undergoing major surgery are at risk of life-threatening inflammatory complications that include infection, the systemic inflammatory response syndrome (SIRS), or sepsis. Although improvements in surgical technique and peri-operative care have resulted in reduction in the rates of these complications, they remain high, especially in patients undergoing complex abdominal procedures...

Development of a dysregulated immune response discriminates sepsis from uncomplicated infection. Currently used biomarkers fail to describe simultaneously occurring pro- and anti-inflammatory responses potentially amenable to therapy. Marker candidates were screened by microarray and, after transfer to a platform allowing point-of-care testing, validated in a confirmation set of 246 medical and surgical patients. We identified up-regulated pathways reflecting innate effector mechanisms, while down-regulated pathways related to adaptive lymphocyte functions...
