Damage-associated molecular patterns (DAMP) trigger innate immune response and exacerbate inflammation to combat infection and cellular damage. Identifying DAMPs and revealing their functions are thus of crucial importance. Here we report that two molecules, N-myc and STAT interactor (NMI) and interferon-induced protein 35 (IFP35) act as DAMPs and are released by activated macrophages during lipopolysaccharide-induced septic shock or acetaminophen-induced liver injury. We show that extracellular NMI and IFP35 activate macrophages to release proinflammatory cytokines by activating nuclear factor-κB through the Toll-like receptor 4 pathway...

Critically ill patients typically present with hyperglycemia. Treatment with conventional insulin therapy (targeting 144-180 mg/dl) improves patient survival; however, intensive insulin therapy (IIT) targeting normal blood glucose levels (81-108 mg/dl) increases the incidence of moderate and severe hypoglycemia, and increases mortality. Septic patients are especially prone to IIT-induced hypoglycemia, but the mechanism remains unknown. Here, we show that codelivery of insulin with otherwise sublethal doses of LPS induced hypoglycemic shock in mice within 1-2 h...

BACKGROUND: Although generally asymptomatic, severe Chlamydia trachomatis (C. trachomatis) infections have been documented. C. trachomatis has been associated with both myocarditis and sepsis. CASE: A 19-year-old female with type 1 diabetes mellitus developed sudden-onset mental status change and shock after resolution of diabetic ketoacidosis. Abdominal and pelvic imaging demonstrated uterine and adnexal inflammation, and pelvic exam confirmed a diagnosis of pelvic inflammatory disease...

Objective: To investigate the prognostic value of highly sensitive cardiac Troponin T (hs-cTn T) for sepsis in critically ill patients. Methods: Patients estimated to stay in the ICU of Fuxing Hospital for more than 24h were enrolled at from March 2014 to December 2014. Serum hs-cTn T was tested within two hours. Univariate and multivariate linear regression analyses were used to determine the association of variables with the hs-cTn T. Multivariable logistic regression analysis was used to evaluate the risk factors of 28-day mortality...

OBJECTIVE: To determine whether the coding strategies used to identify severe sepsis in administrative data sets could identify cases with comparable case mix, hospitalization characteristics, and outcomes as a cohort of children diagnosed with severe sepsis using strict clinical criteria. METHODS: We performed a retrospective cohort study using data from 2005 to 2011 from the New York and Florida State Inpatient Databases, available from the US Healthcare Cost and Utilization Project...

BACKGROUND: Thrombocytopenia is a common feature of sepsis and may involve various mechanisms often related to the inflammatory response. This study aimed at evaluating factors associated with thrombocytopenia during human septic shock. In particular, we used a multiplex analysis to assess the role of endogenous sepsis mediators. METHODS: Prospective, observational study. Thrombocytopenia was defined as an absolute platelet count <100 G/L or a 50% relative decrease in platelet count during the first week of septic shock...

Objective: The purpose of this study was to determine whether an electronic health record-based sepsis alert system could improve quality of care and clinical outcomes for patients with sepsis. Materials and Methods: We performed a patient-level interrupted time series study of emergency department patients with severe sepsis or septic shock between January 2013 and April 2015. The intervention, introduced in February 2014, was a system of interruptive sepsis alerts triggered by abnormal vital signs or laboratory results...

PURPOSE: The third Consensus Definitions for Sepsis and Septic Shock (Sepsis-3) defined sepsis as an organ dysfunction consequent to infection. A SOFA score ≥2 identifies sepsis. In this study, PCT and MR-proADM were evaluated along with SOFA and qSOFA scores in patients with sepsis or septic shock. METHODS: One hundred and nine septic patients and 50 patients with non-infectious disease admitted at the Department of Internal Medicine and General Surgery of the University Hospital Campus Bio-Medico of Rome were enrolled...

PURPOSE OF REVIEW: We reviewed the recent advances in the initial approach to resuscitation of sepsis and septic shock patients. RECENT FINDINGS: Sepsis and septic shock are life-threatening emergencies. Two key interventions in the first hour include timely antibiotic therapy and resuscitation. Before any laboratory results, the need for resuscitation is considered if a patient with suspected infection has low blood pressure (BP) or impaired peripheral circulation found at clinical examination...

Background: Predicting antimicrobial resistance in gram-negative bacteria (GNB) could balance the need for administering appropriate empiric antibiotics while also minimizing the use of clinically unwarranted broad-spectrum agents. Our objective was to develop a practical prediction rule able to identify patients with GNB infection at low risk for resistance to piperacillin-tazobactam (PT), cefepime (CE), and meropenem (ME). Methods: The study included adult patients with sepsis or septic shock due to bloodstream infections caused by GNB admitted between 2008 and 2015 from Barnes-Jewish Hospital...

Postoperative infections are one of the most common complications in general surgery, and while rates have reduced with the routine administration of perioperative antibiotics, around 5% of patients undergoing a surgical procedure will develop an infective complication.(1) The Gram-positive, obligate anaerobe, Clostridium perfringens, is a well-known pathogen that forms part of both the environmental and gastrointestinal flora.(2) While more commonly associated with food poisoning, anaerobic cellulitis and traumatic gas gangrene, rare cases of spontaneous non-traumatic gas gangrene of abdominal viscera have also been recorded...

BACKGROUND: Sepsis is one of the leading causes of death in the UK. AIMS: The aims of this study were to identify the rate of inactive antimicrobial therapy (AMT) in the ICU and whether inactive AMT had an effect on in hospital mortality, ICU mortality, 90-day mortality and length of hospital stay. Additionally, we wanted to identify risk factors for receiving inactive AMT. METHODS: This was a retrospective observational study conducted at Glasgow Royal Infirmary ICU between January 2010 and December 2013, with 12,000 blood cultures taken over this time period, of which n=127 were deemed clinically significant...

BACKGROUND: Sepsis and septic shock are common presentations of infective endocarditis (IE), but little is known about clinical characteristics in this group of patients, use of surgical treatment, and their associations with outcome. We sought to determine the influence of cardiac surgery (CS) on the outcome of patients with IE in different stages of sepsis severity. METHODS: Two hundred ninety four patients with definite IE native or prosthetic valve IE admitted between 2000 and 2011...

AIM: The aim of this study was to investigate the effects of different vasopressors on the cerebral vasculature during experimental human endotoxemia and sepsis. We used the critical closing pressure (CrCP) as a measure of cerebral vascular tone. METHODS: We performed a prospective pilot study, at the intensive care department (ICU) of a tertiary care university hospital in the Netherlands, in 40 healthy male subjects during experimental human endotoxemia (administration of bacterial lipopolysaccharide [LPS]) and in 10 patients with severe sepsis or septic shock...

PURPOSE: The study purpose was to define changes in coagulation across the sepsis spectrum using rotational thromboelastometry (ROTEM). METHODS: Sepsis patients were recruited on admission to the Emergency Department and Intensive Care Units of a large teaching hospital in Wales. ROTEM markers of clot development and fibrinolysis were determined, as well as standard coagulation markers. A healthy control group matched for age and gender was also recruited (n=44)...

ETHNOPHARMACOLOGICAL RELEVANCE: Xuebijing injection (XBJ), a Chinese herbal medicine containing extracts from 5 herbs, is frequently used as an add-on with standard therapies to treat sepsis or septic shock with fewer side effects in China. Nonetheless, its mechanism of action on septic shock remains to be unveiled. We explored the differential effects of XBJ on subtypes of CD4+ T cell differentiation and septic shock protection in a murine model to understand the contribution of XBJ to regulation of the inflammation-immune axis function...
