BACKGROUND: The accumulated evidence suggests that macrophage migration inhibitory factor (MIF) plays a key role not only in acute and chronic inflammatory diseases but also in cardiovascular disease. The cardiac dysfunction is related to lipopolysaccharide (LPS) in sepsis. AIM: This study was designed to examine whether MIF mediates LPS-induced cardiac dysfunction and address the mechanisms. METHODS: Echocardiography, immunohistochemical analysis, cell shortening/relengthening and intracellular Ca2+ fluorescence evaluation were performed in whole hearts and isolated cardiomyocytes from C57 and MIF knockout mice treated with or without LPS...

Diagnosing bacterial infection in the unwell or febrile child is a common challenge faced by all paediatricians. Despite the advent of novel molecular techniques, there is ongoing need for diagnostic assays with adequate performance and turnaround time to facilitate safe clinical decision-making when bacterial sepsis is suspected, such as whether to commence empirical treatment with antibiotics. Procalcitonin is an established marker of infection that has a potential role in the diagnosis and exclusion of serious or invasive bacterial infection in neonates and children...

BACKGROUND: Decreased apolipoprotein A-I (apoA-I) and high-density lipoprotein cholesterol (HDL-C) are common in inflammation and sepsis. No study with a large sample size has been performed to investigate the prognostic value of apoA-I or HDL-C in infective endocarditis (IE). OBJECTIVE: The present study aimed to explore the prognostic value of apoA-I and HDL-C for adverse outcomes in IE patients. METHODS: Patients with a definite diagnosis of IE between January 2009 and July 2015 were enrolled and divided into 3 groups according to their apoA-I tertiles at admission...

The presence of pre-existing malignancy in murine hosts results in increased immune dysregulation and risk of mortality following a septic insult. Based on the known systemic immunologic changes that occur in cancer hosts, we hypothesized that the presence of pre-existing malignancy would result in phenotypic and functional changes in CD4+ T cell responses following sepsis. In order to conduct a non-biased, unsupervised analysis of phenotypic differences between CD4+ T cell compartments, cohorts of mice were injected with LLC1 tumor cells and tumors were allowed to grow for 3 weeks...

BACKGROUND: Perinatal asphyxia (PA) occurs in about 2 to 10 per 1000 live full-term births. Although neonatal epileptic seizures are observed in up to 60% of cases, PA may mimic or subtend other conditions. Hypoxia related brain injury is particularly relevant, as it may have permanent effects on neuropsychomotor development. Antepartum obstetric conditions, may, in turn, lead to hypoxic-ischemic damage to the fetus and the newborn, often underlying PA. Herein, a case of PA that hid and triggered signs and symptoms of Glutaric Aciduria type I (GA-I), is reported...

BACKGROUND: High levels of circulating GLP-1 are associated with severity of sepsis in critically ill non-diabetic patients. Whether type 2 diabetes (T2D) patients display different activation of the endogenous GLP-1 system during sepsis and whether it is affected by diabetes related metabolic parameters is not known. METHODS: Serum levels of GLP-1 (total and active forms) and its inhibitor enzyme sDPP-4 were determined by ELISA on admission and after 2-4 days in 37 sepsis patients with (n=13) and without T2D (n=24) and compared to normal healthy controls (n=25)...

Herein a label-free immunosensor based on electrolyte-gated organic field-effect transistor (EGOFET) was developed for the detection of procalcitonin (PCT), a sepsis marker. Antibodies specific to PCT were immobilized on the poly-3-hexylthiophene (P3HT) organic semiconductor surface through direct physical adsorption followed by a post-treatment with bovine serum albumin (BSA) which served as the blocking agent to prevent non-specific adsorption. Antibodies together with BSA (forming the whole biorecognition layer) served to selectively capture the procalcitonin target analyte...

Sepsis is a systemic response to infection that can result in acute hepatic and splenic damage. Ziziphus spina-christi (L.) is a wild tree used as a medicinal plant by ancient Egyptians. However, little is known about the mechanism underlying its effects on sepsis. The current study investigated the protective effects of a Z. spina-christi leaf extract (ZSCLE) on liver and spleen damage in a male C57BL/6 mouse model of sepsis, induced by cecal ligation and puncture (CLP). Prior to CLP, ZSCLE was administered daily for five consecutive days via oral gavage at doses of 100, 200, or 300 mg/kg...

OBJECTIVE: Neonatal sepsis is a major cause of mortality in the developing countries. However, with current severity scores and laboratory parameters, predicting outcomes of neonatal sepsis is a serious challenge. Red cell distribution width (RDW) is a readily available pragmatic means to predict outcomes of various comorbidities in adults and children, without causing any additional blood loss. However, its utility in neonates remains unexplored. Hence, the objective of the present study was to evaluate the association of RDW with neonatal sepsis and its role as a predictive marker for mortality...

Systemic inflammation is emerging as a significant driver of cognitive decline in the aged and vulnerable brain. In sepsis survivors animals low-grade brain inflammation occurs, suggesting that sepsis is able to induce in microglia a primed-like state. The purpose of this study is to analyze the role of sepsis-induced brain inflammation in the progression of the physiological process of brain aging. Wistar rats 2month-old were subjected to sepsis and 60 and 90days after were submitted to the new object recognition test and brain was removed to the determination of cytokines, myeloperoxidase (MPO) activity, amyloid-beta peptide (Aβ) and immunohistochemistry markers of microglial activation...

Serum soluble interleukin-2 receptor (sIL-2r) is an important disease marker in hemophagocytic lymphohistiocytosis (HLH), but there are no published data on its diagnostic value in adults. We conducted a single-center retrospective study of 78 consecutive adults who had sIL-2r measured for suspected HLH. Serum sIL-2r levels were measured by enzyme-linked immunosorbent assay (adult reference range, 241-846 U/mL). There were 38 patients with HLH and 40 with a non-HLH diagnosis (such as sepsis, liver disease, histiocyte disorders, autoimmune disease, leukemia, or lymphoma)...

Alarming increase of death due to S. aureus sepsis demands newer treatment strategies. Enhancement of antibiotic resistant S. aureus strains caused increased mortality. Only antibiotic treatment for Staphylococcal sepsis has been found insufficient to improve outcomes. In the innate immune response, phagocytosis mediated killing of pathogen and further triggering of intracellular signaling cascades by the PRRs culminates in the release of a variety of pro inflammatory cytokines, which orchestrate together in the early host response to infection...
