PURPOSE: The aim of this study was to identify specific laboratory indices to distinguish Epstein-Barr virus-associated hemophagocytic lymphohistiocytosis (EBV-HLH) in children. MATERIALS AND METHODS: In this prospective study, Th1/Th2 cytokines, including IL-2, IL-4, IL-6, IL-10, TNF-α, and IFN-γ, were analyzed in patients with EBV-HLH or sepsis at the onset of disease by flow cytometry. RESULTS: IL-10, IFN-γ, IL-10/IL-6, and IFN-γ/IL-6 were higher and IL-6 was lower in EBV-HLH patients compared to sepsis patient levels...

Mid-regional pro-adrenomedullin (MR-proADM) has been used as a marker of sepsis, but its dynamics and role in a burn injury setting has not been tested. In a prospective observational study, we included 42 consecutive patients with >15% TBSA. Daily blood specimens collected during the initial 20 days of treatment were submitted for laboratory analysis of MR-proADM and procalcitonin (PCT) via immunoluminometric sandwich assay (Kryptor, BRAHMS, Berlin, Germany). In patients with an absence of sepsis, an initial increase in MR-proADM and PCT levels was noted post burn injury, peaking on the second day post admission and thereafter demonstrated a continued decline in MR-proADM and PCT levels...

PURPOSE: The definitions of sepsis and septic shock have recently been revised in adults, but contemporary data are needed to inform similar approaches in children. METHODS: Multicenter cohort study including children <16 years admitted with sepsis or septic shock to ICUs in Australia and New Zealand in the period 2012-2015. We assessed septic shock criteria at ICU admission to define sepsis severity, using 30-day mortality as outcome. Through multivariable logistic regression, a pediatric sepsis score was derived using variables available within 60 min of ICU admission...

This paper describes the evolution of our understanding of the biological role played by synthetic and natural antimicrobial cationic peptides and by the highly basic nuclear histones as modulators of infection, postinfectious sequelae, trauma, and coagulation phenomena. The authors discuss the effects of the synthetic polymers of basic poly α amino acids, poly l-lysine, and poly l-arginine on blood coagulation, fibrinolysis, bacterial killing, and blood vessels; the properties of natural and synthetic antimicrobial cationic peptides as potential replacements or adjuncts to antibiotics; polycations as opsonizing agents promoting endocytosis/phagocytosis; polycations and muramidases as activators of autolytic wall enzymes in bacteria, causing bacteriolysis and tissue damage; and polycations and nuclear histones as potential virulence factors and as markers of sepsis, septic shock, disseminated intravasclar coagulopathy, acute lung injury, pancreatitis, trauma, and other additional clinical disorders...

Sepsis is a systemic host response to infection, and patients with sepsis are frequently handled in the intensive care unit. However, mortality related to sepsis remains high throughout the world. In addition, there have been no efficient prognostic biomarkers for sepsis to be employed in clinical practice. We therefore aimed to identify prognostic biomarkers for sepsis using the chemokine/cytokine array. This study included 143 patients with sepsis, who were divided into survivor and nonsurvivor groups according to their 28-day mortality status...

Muscle wasting is one of the main contributors to the worse outcomes in sepsis. Whether estrogen could alleviate muscle wasting induced by sepsis remains unclear. This study was designed to test the effect of estrogen on muscle wasting and its relationship with central alteration in sepsis. Thirty Sprague-Dawley rats were divided into 3 groups: control group, sepsis group, and estrogen treated sepsis group. Animals were intraperitoneally injected with lipopolysaccharide (10 mg/kg) or saline, followed by subcutaneous injection of 17β-estradiol (1 mg/kg) or saline...

Endothelial glycocalyx (EG) is disintegrated during sepsis. We showed (Am J Pathol, 2016) that this occurs very early in the course of sepsis and its prevention improves survival of mice with sepsis. Here, we sought to investigate the possibility to pharmacologically accelerate the restoration of disintegrated EG in sepsis. We used a soilage injection model to induce polymicrobial sepsis in C57/BL6 mice and measured total body EG. En face aortic preparations were used for staining for markers of EG and atomic force microscopy (AFM) was used to measure EG in vitro...

Many surface virulence factors of bacterial pathogens show mosaicism and confounding phylogenetic origin. The Streptococcus gordonii platelet-binding GspB protein, the Streptococcus sanguinis SrpA adhesin and the Streptococcus pneumoniae DiiA protein, share an imperfect 27-residue motif. Given the disparate domain architectures of these proteins and its association to invasive disease, this motif was named MiiA from Multiarchitecture invasion-involved motif A. MiiA is predicted to adopt a beta-sheet folding, probably related to the Ig-like fold, with a symmetrical positioning of two conserved aspartic residues...

BACKGROUND: A high percentage of critically ill polytrauma patients develop acute respiratory distress syndrome (ARDS), both because of the primary traumatic injuries and because of the secondary post-traumatic injuries. For adequate management of these patients, new complex evaluation and monitoring methods are needed, methods that could answer as many questions as possible regarding the pathophysiological changes associated with ARDS. Currently, a series of clinical and biochemical markers are being used which unfortunately do not respond to the needs of an intensive care clinician...

BACKGROUND: Sepsis induced acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are lifethreatening disorders. Acute Physiology and Chronic Health Evaluation (APACHE) scores and several plasma biological markers have been identified to predict the death or treatment outcome of sepsis induced ALI. Immune related microRNAs also have the potential as biomarkers to monitor this kind of disease. METHODS: A total of 44 patients with severe sepsis, 102 patients with sepsis, and 19 healthy volunteers were enrolled in this study...

BACKGROUND: Cell free DNA (cfDNA) was recently suggested as a new marker of sepsis and poor outcome in ICU patients. Procalcitonin has also been the focus of attention as an early marker for systemic inflammation and sepsis. METHODS: cfDNA, procalcitonin (PCT), C-reactive protein (CRP), and lactate levels were measured in 30 ICU patients with multiple trauma or after major surgery on the first day of admission and on 5th and 7th days for PCT, CRP, and lactate. cfDNA was measured by real-time PCR, PCT by ELISA, CRP immunoturbidimetrically, and lactate spectrophotometrically...

Despite sepsis being a life-threatening disease, targeted drugs that improve the therapy of affected patients are still lacking. Infants and adults differ in the maturity level of their immune system and this results in distinct reactions to Gram-negative bacteria. To study reactions of human immune cells in vivo, we used NOD scid gamma mice transplanted with human CD34(+) stem cells to engraft a functional human immune system. Human cells undergo differentiation and maturation in these mice after transplantation and, accordingly, animals were divided into two groups: 8-13 wk and 15-22 wk after transplantation...

OBJECTIVE: This study comparatively evaluated the value of dynamic procalcitonin (PCT) and presepsin measurements in assessing therapeutic efficacy and prognosis for patients with severe sepsis. METHODS: Patients with severe sepsis (n=109) were enrolled and divided into survival and non-survival groups based on 90-day survival. PCT and presepsin levels were evaluated on days 1, 3, 5, 7, and 12. Sequential organ failure assessment (SOFA) was calculated. RESULTS: PCT from day 5 onward was weakly to moderately positively correlated with SOFA, whereas presepsin from day 3 onward was positively correlated...
