Sepsis outcomes are heavily dependent on the development of septic organ injury, but no interventions exist to interrupt or reverse this process. MicroRNA-223 (miR-223) is known to be involved in both inflammatory gene regulation and host-pathogen interactions key to the pathogenesis of sepsis. The goal of this study was to determine the role of miR-223 as a mediator of septic kidney injury. Using miR-223 knockout mice and multiple models of experimental sepsis, we found that miR-223 differentially influences acute kidney injury (AKI) based on the model used...

BACKGROUND: Culture negative neutrocytic ascites is a variant of spontaneous bacterial peritonitis. But there are conflicting reports regarding the mortality associated with culture negativeneutrocytic ascites. Therefore we aim to determine the predictors of mortality associated with culture negativeneutrocytic ascites in a larger sample population. METHODS: We analysed 170 patients consecutively admitted to intensive care unit with diagnosis of culture negative neutrocytic ascites...

BACKGROUND: Endotoxins contribute to systemic inflammatory response and microcirculatory dysfunctions under conditions of sepsis. Polymyxin B hemoperfusion (PMX-HP) is used to remove circulating endotoxins and improve clinical outcomes. This study aims to investigate the effect of PMX-HP on microcirculation in septic pigs. MATERIALS AND METHODS: By using a septic pig model, we tested the hypothesis that PMX-HP can correct intestinal microcirculation, tissue oxygenation saturation, and histopathologic alterations...

A previous study found that an AAAG-rich Oligodeoxynucleotide (ODN), designated as MS19, could lessen the acute lung inflammatory injury (ALII) in mice infected by influenza viruses. Bioinformatics analysis found that MS19 is consensus with the binding site of interferon regulatory factor 5 (IRF5) in the regulatory elements of pro-inflammatory genes. This study established a septic peritonitis model in Institute of Cancer Research (ICR) mice infected with Escherichia coli (E. coli), and found that MS19 prolonged the survival of the mice and down-regulated the expression of inducible nitric oxide synthase (iNOS), interleukin-6 (IL-6), and tumor necrosis factor α (TNF-α)...

Aloe, a polyphenolic anthranoid-containing Aloe vera leaves, is a Chinese medicine and a popular dietary supplement worldwide. In in vivo situations, polyphenolic anthranoids are extensively broken down into glucuronides and sulfate metabolites by the gut and the liver. The anti-inflammatory potential of aloe metabolites has not been examined. The aim of this study was to investigate the anti-inflammatory effects of aloe metabolites from in vitro (lipopolysaccharides (LPS)-activated RAW264.7 macrophages) and ex vivo (LPS-activated peritoneal macrophages) to in vivo (LPS-induced septic mice)...

BACKGROUND: Open abdomen with vacuum assisted closure (VAC) is an alternate method to primary abdominal closure (PAC) in select situations for the management of severe surgical abdominal sepsis or septic shock. Peritoneal cytokines may potentially correlate with deranged physiology and help stratify severity of sepsis. The primary objective of the study was to identify if cytokines can differentiate between patients who underwent PAC or VAC at primary source control laparotomy (SCL). METHODS: Prospective case series including patients with severe abdominal sepsis/septic shock requiring urgent SCL...

Depression of heart-rate variability (HRV) in conditions of systemic inflammation has been shown in both patients and experimental animal models and HRV has been suggested as an early indicator of sepsis. The sensitivity of HRV-derived parameters to the severity of sepsis, however, remains unclear. In this study we modified the clinically relevant porcine model of peritonitis-induced sepsis in order to avoid the development of organ failure and to test the sensitivity of HRV to such non-severe conditions. In 11 anesthetized, mechanically ventilated and instrumented domestic pigs of both sexes, sepsis was induced by fecal peritonitis...

INTRODUCTION: Negative pressure wound therapy (NPWT) is widely used in the treatment of open abdomen (OA). The use of dynamic fascial sutures (DFS) increases the rate of successful delayed closure by reducing fascial lateralization. We recently published a prospective controlled trial including 87 patients undergoing abdominal surgery for secondary peritonitis between 2007 and 2012. Patients were treated with NPWT and DFS for approximation of fascial edges. The present study represents a follow-up assessment of these patients 5-9 years after OA treatment with NPWT and DFS...

BACKGROUND: Weekly administration of solvent-based paclitaxel is one of the standard second-line chemotherapy regimens for advanced gastric cancer. Nanoparticle albumin-bound paclitaxel (nab-paclitaxel) was developed to improve the solubility of paclitaxel and does not need premedication to avoid infusion-related reactions associated with solvent-based paclitaxel. Additionally, higher doses of nab-paclitaxel can be administered over a shorter infusion time and at higher drug concentrations compared with solvent-based paclitaxel...

Corylin is a main compound isolated from Psoralea corylifolia L. (Fabaceae). A variety of pharmacological effects such as antioxidant, anti-proliferation, and anti-inflammatory properties of corylin have been reported. Nevertheless, the effect of corylin in microbial infection and sepsis remains unclear. In the present study, we investigated the anti-inflammatory effects of corylin. Our experimental results demonstrated that corylin inhibited the production of TNF-α, IL-6 and NO by both LPS-activated RAW 264...

BACKGROUND: Sepsis is a major cause of mortality in Intensive Care Units. Anesthetic dose isoflurane and 100% oxygen were proved to be beneficial in sepsis; however, their application in septic patients is limited because long-term hyperoxia may induce oxygen toxicity and anesthetic dose isoflurane has potential adverse consequences. This study was scheduled to find the optimal combination of isoflurane and oxygen in protecting experimental sepsis and its mechanisms. METHODS: The effects of combined therapy with isoflurane and oxygen on lung injury and sepsis were determined in animal models of sepsis induced by cecal ligation and puncture (CLP) or intraperitoneal injection of lipopolysaccharide (LPS) or zymosan...

Derangements of microvascular blood flow distribution might contribute to disturbing oxygen extraction by peripheral tissues. We evaluated the dynamic relationships between the mesenteric oxygen extraction ratio (mes-ERO2) and the heterogeneity of microvascular blood flow at the gut and sublingual mucosa, during the development and resuscitation of septic shock in a swine model of fecal peritonitis. Jejunal-villi and sublingual microcirculation were evaluated using a portable intravital-microscopy technique...

Background. Previous studies assessing various cytokines in the critically ill/injured have been uninformative in terms of translating to clinical care management. Animal abdominal sepsis work suggests that enhanced intraperitoneal (IP) clearance of Damage-Associated Molecular Patterns (DAMPs) improves outcome. Thus measuring the responses of DAMPs offers alternate potential insights and a representative DAMP, High Mobility Group Box-1 protein (HMGB-1), was considered. While IP biomediators are being recognized in critical illness/trauma, HMGB-1 behaviour has not been examined in open abdomen (OA) management...

Septic peritonitis is a relatively common condition in the veterinary intensive care unit, with a classically high mortality rate. Early enteral nutrition (EEN) in critically ill humans can lead to improved outcome. This study was performed to determine the safety of early postoperative feeding in canine septic peritonitis. In this retrospective case series, 56 dogs were identified. Sixteen dogs received EEN, defined as nutrition within 24 hr of surgery; 27 received late enteral nutrition (LEN) defined as nutrition more than 24 hours following surgery; and 13 dogs had no enteral nutrition in hospital (NEN)...

Recently, a serial of studies have demonstrated that lipid mediators derived from Omega-3 fatty acid docosahexaenoic acid have pro-resolving or anti-inflammatory effects in many inflammatory diseases. Here, we sought to evaluate whether Protectin DX (PDX, an isomer of Protecin D1), a newly identified lipid mediator, could protect mice against sepsis and explore the underling mechanism. Animal model of sepsis was established by cecum ligation and puncture (CLP). We found that PDX increased overall survival rate within eight days and attenuated multiple organ injury in septic mice...

INTRODUCTION: Prostatic abscess is a rare but relatively serious infectious disease; its association with spontaneous rupture is extremely unusual. PRESENTATION OF CASE: We present a case of peritonitis secondary to a rupture of prostatic abscess in a 87-year-old man. The diagnosis was made on computed tomography. Emergency laparotomy, transrectal ultrasonography guided aspiration of the residual abscess and antibiotics permitted a full recovery. DISCUSSION: Delay in diagnosis of prostatic abscess can have grave sequelae, including spontaneous rupture into the urethra, perineum, bladder or rectum and the development of septic shock...

BACKGROUND: The management of a septic peritonitis open abdomen is a serious problem for clinicians. Open surgery is associated with several complications such as bleeding and perforation of the bowel. CASE PRESENTATION: The authors report a case of a 59-years-old female who underwent a sigmoid resection with an latero-terminal (L-T) anastomosis for the perforation of a diverticulum. After a few days the patients developed a new widespread peritonitis. At the emergency re-laparotomy, surgeons found dehiscence of the posterior wall of the anastomosis with fecal contamination...
