Although advances in medical care have significantly improved sepsis survival, sepsis remains the leading cause of death in the ICU. This is likely due to a lack of complete understanding of the pathophysiologic mechanisms that lead to dysfunctional immunity. Neutrophil derived microparticles (NDMPs) have been shown to be the predominant microparticle present at infectious and inflamed foci in human models, however their effect on the immune response to inflammation and infection is sepsis has not been fully elucidated...

Decreased levels of endogenous hydrogen sulfide (H2S) contribute to atherosclerosis, whereas equivocal data are available on H2S effects during sepsis. Moreover, H2S improved glucose utilization in anaesthetized, ventilated, hypothermic mice, but normothermia and/or sepsis blunted this effect. The metabolic effects of H2S in large animals are controversial. Therefore, we investigated the effects of the H2S donor GYY4137 during resuscitated, fecal peritonitis-induced septic shock in swine with genetically and diet-induced coronary artery disease (CAD)...

Background Gastric rupture is a rare, life-threatening condition during pregnancy. Case study We present three cases of gastric perforation during pregnancy and the puerperium. The first patient presented with gastric perforation 4 days following an uncomplicated cesarean delivery for obstetric indications. She initially complained of epigastric pain; however, those symptoms resolved. She later demonstrated worsening abdominal distension, intra-abdominal free fluid, and signs of peritonitis. At laparotomy, an ascariasis-associated gastric rupture was diagnosed...

Critical illness can be associated with transient alterations in circulating thyroid hormones concentration indicating Non-Thyroidal Illness (NTI). NTI is well described in humans; literature concerning its occurrence and prognostic significance in dogs remains limited. The aim of this retrospective study was to assess the occurrence of NTI in a population of dogs with Systemic Inflammatory Response Syndrome (SIRS), and to investigate its association with disease severity (Apple Fast Score). A total of 41 SIRS dogs (acute pancreatitis n=10; parvovirus n=22; septic peritonitis n=9) were included, and divided according to SIRS origin (non-septic SIRS: acute pancreatitis; septic-SIRS: parvovirus and septic peritonitis) and final outcome (survivors, n=37; non-survivors, n=4)...

Steroid receptor coactivator 3 (SRC-3) is a transcriptional coactivator that interacts with nuclear receptors and some other transcription factors to enhance their effects on target gene transcription. We reported previously that SRC-3-deficient (SRC-3(-/-)) mice are extremely susceptible to Escherichia coli-induced septic peritonitis as a result of uncontrolled inflammation and a defect in bacterial clearance. In this study, we observed significant upregulation of SRC-3 in colonic epithelial cells in response to Citrobacter rodentium infection...

RATIONALE: Heterogeneity in the septic response has hindered efforts to understand pathophysiology and develop targeted therapies. Source of infection, with different causative organisms and temporal changes, might influence this heterogeneity. OBJECTIVES: To investigate individual and temporal variation in the transcriptomic response to sepsis due to fecal peritonitis, and to compare with community acquired pneumonia. METHODS: We performed genome-wide gene expression profiling in peripheral blood leukocytes for adult patients admitted to intensive care with sepsis due to fecal peritonitis (n=117) or community acquired pneumonia (n=126), and non-septic controls (n=10)...

BACKGROUND: Splenic abscesses are rare entities; reports are commonly described in immunocompromised patients (72%) as: hematologic diseases, diabetes, endocarditis, acquired immunodeficiency syndrome, transplant patients and subjects who had abdominal trauma or splenic infarction. The main and most serious complication is the abscess rupture into the peritoneal cavity or adjacent organs (stomach or colon), which determines hemodynamic instability or septic state. CLINICAL CASE: Fifty-year-old man, who was admitted at Emergency Room due eight days' progressive, oppressive, and current pain; intensity 4/10, irradiated at hemi-back, which was higher intensity during the standing and decreased at supine position...

BACKGROUND: Sepsis and the ensuing immune dysfunction continue to be major contributors to neonatal morbidity and mortality. Neonatal sepsis also is associated with profound immune dysfunction. We have recently identified a role for a family of coinhibitory molecules that are altered in murine sepsis and in critically ill adult patients, which may be a target for development of novel therapies. There is, however, a paucity of data pertaining to the role of coinhibitory checkpoint proteins in the control and modulation of neonatal sepsis...

Sepsis continues to result in high morbidity and mortality. General anesthesia is often administered to septic patients, but the impacts of general anesthesia on host defense are not well understood. General anesthesia can be given by volatile and intravenous anesthetics. Our previous in vitro study showed that volatile anesthetic isoflurane directly inhibits leukocyte function-associated antigen-1 (LFA-1) and macrophage-1 antigen (Mac-1), critical adhesion molecules on leukocytes. Thus, the role of isoflurane exposure on in vivo LFA-1 and Mac-1 function was examined using polymicrobial abdominal sepsis model in mice...

BACKGROUND: Sepsis remains a leading cause of death in most intensive care units. Many deaths in sepsis are due to nosocomial infections in patients who have entered the immunosuppressive phase of the disorder. One cause of immunosuppression in sepsis is T-cell exhaustion mediated by programmed cell death-1 (PD-1) interaction with its ligand (PD-L1). Studies demonstrated that blocking the interaction of PD-1 with PD-L1 with knockout mice or inhibitory antibodies reversed T-cell dysfunction and improved sepsis survival...

BACKGROUND: The etiology of renal dysfunction in sepsis is currently attributed to altered perfusion, microcirculatory abnormalities and cellular alterations. To clarify these mechanisms, we characterized the changes in renal perfusion and cortex metabolism in a large animal model of sepsis. METHODS: We studied 12 adult female sheep randomized to peritonitis-induced sepsis (n = 8) or to sham procedure (n = 4). A flow probe was positioned around the renal artery to measure renal blood flow (RBF)...

Sepsis is accompanied by the initial activation of proinflammatory pathways and long-lasting immunosuppression that appears to contribute to late-occurring mortality. Although high-mobility group box 1 (HMGB1) is involved in many aspects of inflammation, its role in sepsis-induced immune suppression remains unclear. In this study, we examined HMGB1's contribution to neutrophil NADPH oxidase activity dysfunction and associated neutrophil-dependent bacterial clearance in mice subjected to sepsis and in patients who survive septic shock...
