BACKGROUND: Septic shock-induced disseminated intravascular coagulation is responsible for increased occurrence of multiple organ dysfunction and mortality. Immunothrombosis-induced coagulopathy may contribute to hypercoagulability. We aimed at determining whether recombinant human thrombomodulin (rhTM) could control exaggerated immunothrombosis by studying procoagulant responses, fibrinolysis activity borne by microvesicles (MVs) and NETosis in septic shock. METHODS: In a septic shock model after a cecal ligation and puncture-induced peritonitis (H0), rats were treated with rhTM or a placebo at H18, resuscitated and monitored during 4 h...

Abortion is a global problem. Maternal mortality and morbidity is still high due to uncontrolled abortion mainly induced abortion which may turn to septic abortion. A total of 50 cases of septic abortion cases admitted in Dhaka Medical College Hospital were included in this study. This cross sectional study was designed to find out the clinical presentation and outcome of septic abortion from January 2010 to January 2011. Out of 50 cases of septic abortion admitted where 44(88%) were induced abortion. Majority of the cases were parous (2-3 parity 32%; 4-6 parity 38%; and 6+ parity 4%) and housewives 42(84%), living with their husbands 49(98%), hailing from urban, semi urban and urban slums...

The colon ascendens stent peritonitis (CASP) surgery creates a leakage of intestinal contents, resulting in polymicrobial sepsis associated with a high risk for postoperative multiple organ failure and death in surgical patients. To evaluate the effects of CASP on multiple organs, we analyzed the systemic metabolic consequences in liver, kidney, lung and heart of rats after CASP by employing a combination of metabolomics, clinical chemistry and biological assays. We found that CASP surgery after 18 h caused significant elevations of lipid, amino acids, acetate, choline, PC and GPC in rat liver together with significant depletion of glucose and glycogen...

The inflammasome is a multiprotein signaling complex that mediates inflammatory innate immune responses through caspase 1 activation and subsequent IL-1β secretion. Nonetheless, its aberrant activation often leads to inflammatory diseases. Therefore, targeting the inflammasome holds promise for the treatment of inflammation-related diseases. Our study showed that a hot-water extract of Sanguisorba officinalis (HSO) effectively suppressed inflammasome activation triggered by ATP, nigericin, microbial pathogens, and dsDNA in bone marrow-derived macrophages (BMDMs)...

Cereblon (CRBN) has a pleiotropic role in important cellular processes and is a potential therapeutic target in several diseases, including mental retardation, cancer, and metabolic disorders. The role of CRBN in polymicrobial sepsis induced by cecal ligation and puncture (CLP) was investigated using CRBN-deficient (KO) mice. Survival following CLP was significantly higher in KO mice compared to wild-type (WT) controls (50% vs 0% at day 6 after CLP). The improved survival of KO mice was accompanied by reduced peripheral blood bacterial load and lung injury...

INTRODUCTION: Sepsis-induced myopathy and critical illness myopathy are common causes of muscle weakness in intensive care patients. This study investigated the effect of different mean arterial blood pressure (MAP) levels on muscle membrane properties following experimental sepsis. METHODS: Sepsis was induced with faecal peritonitis in 12 out of 18 anesthetized and mechanically ventilated pigs. Seven were treated with a high (75-85 mm Hg) and 5 with a low (≥60 mm Hg) MAP target for resuscitation...

Sepsis continues to be a major healthcare issue with one of the highest mortality rates in intensive care units. Toll-like receptors are pattern recognition receptors that are intricately involved in the pathogenesis of sepsis. TLR3 is a major receptor for double-stranded RNA and is largely associated with immunity to viral infection. In this study, we examined the role of TLR3 priming in the immunopathology of sepsis using cecal-ligation and puncture (CLP) model of sepsis in mice. Mice injected with vehicle or poly(I:C) were subjected to sham or CLP surgery and various parameters of sepsis, including mortality, inflammation, and bacterial clearance were assessed...

BACKGROUND: Peritoneal dialysis (PD) for acute kidney injury (AKI) of newborns has been performed safely. AKI occurs in 8 to 24% of extremely low birth weight (ELBW) infants. Although PD has only been used occasionally in ELBW infants, prognosis is poor for ELBW infants with AKI. Several reports have described successful PD in these infants, but no guideline-based evidence concerning indications for renal replacement therapy in ELBW infants are currently available. Here, we report on our experience with PD in an ELBW infant with AKI resulting from septic shock...

Tight junctions (TJs) are a critical component in maintaining the intestinal mucosal barrier function and gastrointestinal health of animals. Gut barrier dysfunction contributes to the initiation and development of sepsis which induces an uncontrollable systemic inflammatory response and gives rise to life‑threatening clinical conditions. Excretory‑secretary antigens from Trichimella spiralis (T. spiralis) have been reported to protect from sepsis in a mouse model, however the mechanism remains to be elucidated...

Sepsis is an infection-induced systemic inflammatory syndrome and a major cause of death for critically ill patients. Here, we examined whether the absence of Sprouty-related EVH1-domain-containing protein 2 (Spred2), a negative regulator of the Ras/Raf/ERK/MAPK pathway, influences host defense against polymicrobial sepsis (PMS) induced by cecal ligation and puncture (CLP). Compared to wild-type mice, Spred2(-/-) mice exhibited higher survival rates with increased level of leukocyte infiltration and local chemokine production and reduced plasma and peritoneal bacterial loads after CLP...

The emphysematous cystitis is a rare condition characterized by the presence of air in the wall and/or the bladder lumen. The clinical expression of this cystitis is variable. Some patients complain of abdominal pain or urinary symptoms. Other may present only pneumaturia or be totally asymptomatic. This condition is considered as potentially severe since it can lead to an emphysematous pyelonephritis with septicemia and septic shock. Peritonitis may also occur in case of necrosis and perforation of the bladder wall...

The host injury involved in multiorgan system failure during severe inflammation is mediated, in part, by massive infiltration and sequestration of hyperactive neutrophils in the visceral organ. A recombinant form of human activated protein C (rhAPC) has shown cytoprotective and anti-inflammatory functions in some clinical and animal studies, but the direct mechanism is not fully understood. Recently, we reported that, during endotoxemia and severe polymicrobial peritonitis, integrin VLA-3 (CD49c/CD29) is specifically upregulated on hyperinflammatory neutrophils and that targeting the VLA-3(high) neutrophil subpopulation improved survival in mice...
