Abstract
BACKGROUND Severe complicated intra-abdominal sepsis (SCIAS) has an increasing incidence with mortality rates over 80% in some settings. Mortality typically results from disruption of the gastrointestinal tract, progressive and self-perpetuating bio-mediator generation, systemic inflammation, and multiple organ failure. A further therapeutic option may be open abdomen (OA) management with negative peritoneal pressure therapy (NPPT) to remove inflammatory ascites and attenuate the systemic damage from SCIAS, although there are definite risks of leaving the abdomen open whenever it might possibly be closed. This potential therapeutic paradigm is the rationale being assessed in the Closed Or Open after Laparotomy (COOL trial) ( https://clinicaltrials.gov/ct2/show/NCT03163095 ). Initially, the COOL trial received Industry sponsorship; however, this funding mandated the use of a specific trademarked and expensive NPPT device in half of the patients allocated to the intervention (open) arm. In August 2022, the 3 M/Acelity Corporation without consultation but within the terms of the contract canceled the financial support of the trial. Although creating financial difficulty, there is now no restriction on specific NPPT devices and removing a cost-prohibitive intervention creates an opportunity to expand the COOL trial to a truly global basis. This document describes the evolution of the COOL trial, with a focus on future opportunities for global growth of the study. METHODS The COOL trial is the largest prospective randomized controlled trial examining the random allocation of SCIAS patients intra-operatively to either formal closure of the fascia or the use of the OA with an application of an NPPT dressing. Patients are eligible if they have free uncontained intraperitoneal contamination and physiologic derangements exemplified by septic shock OR severely adverse predicted clinical outcomes. The primary outcome is intended to definitively inform global practice by conclusively evaluating 90-day survival. Initial recruitment has been lower than hoped but satisfactory, and the COOL steering committee and trial investigators intend with increased global support to continue enrollment until recruitment ensures a definitive answer. DISCUSSION OA is mandated in many cases of SCIAS such as the risk of abdominal compartment syndrome associated with closure, or a planned second look as for example part of "damage control"; however, improved source control (locally and systemically) is the most uncertain indication for an OA. The COOL trial seeks to expand potential sites and proceed with the evaluation of NPPT agnostic to device, to properly examine the hypothesis that this treatment attenuates systemic damage and improves survival. This approach will not affect internal validity and should improve the external validity of any observed results of the intervention.

Abstract
Bacterial peritonitis is a severe disease that diagnosis remains challenging for clinicians. Measuring biomarkers might be a rapid diagnostic method. The objective of this study was to analyze and evaluate the dynamic changes in HIF-1α concentration in serum exosomes during bacterial peritonitis. The pre-clinical application value of serum exosomal HIF-1α was evaluated via imipenem and cilastatin sodium (ICS) intervention in the bacterial peritonitis model. The new colorimetric method to quantitate dynamic expression changes of HIF-1α in serum exosomes during bacterial peritonitis was established by our team via using the gold seed-coated with aptamer-functionalized Au @ Au core-shell peroxidase mimic. The typical inflammatory cytokines of bacterial peritonitis were also measured. Following intramuscular administration with ICS, In-Vivo Xtreme imaging system was used to visualize abdominal infection extent. Meanwhile, HIF-1α concentration in rat serum exosomes and pro-inflammatory factors levels in serum were detected. The serum typical inflammatory cytokines levels were elevated in GFP-labelled E.coli induced bacterial peritonitis. The serum exosomal HIF-1α levels clearly increased at 12 h, reached the peak during 24-48 h, and then gradually decreased at 72 h. Following intramuscular administration with ICS, the abdominal infection extent, HIF-1α concentration in serum exosomes, and the serum pro-inflammatory factors levels were reduced at 24 h in GFP-labelled E. coli induced bacterial peritonitis model. The serum exosomal HIF-1α can be used as a biomarker in the early stage of bacterial peritonitis, which might provide the basic research in the pre-clinical for further predicting and monitoring the pathological process of bacterial peritonitis.

Abstract
BACKGROUND It is still a matter of debate what the best management of peritonitis is following eliminating the source of infection. This particularly concerns the amplitude of local and systemic inflammatory response as well as bacterial clearence at the infectious site. AIM To investigate the effects of vacuum-assisted closure (VAC) vs. relaparotomy on demand (ROD) onto the i) severity and course of disease, ii) surgical outcome, iii) intraperitoneal bacterial load as well as iv) local and systemic inflammatory and immune response in postoperative secondary peritonitis. METHODS Over a defined time period, all consecutive patients of the reporting surgical department with a secondary peritonitis (assessed by Mannheim's Peritonitis Index [MPI] and APPACHE II score) were enrolled in this systematic unicenter clinical prospective observational pilot study reflecting daily surgical practice and as a contribution to internal quality assurance. Patients were subclassified into VAC or ROD group according to surgeon's individual decision at the time point of primary surgical intervention with the intent to sanitize the source of infection. Early postoperative result was assessed by 30-d and in-hospital mortality. Bacterial load was characterized by microbiological culture of intraperitoneal fluid collection obtained on postoperative days (POD) 0 (primary surgical intervention), 1, 4, 7, 10, 13 and following description of the microbial spectrum including semiquantitative assessment of bacterial load. Local and systemic inflammatory and immune response was determined by ELISA-based analysis of CrP, PCT and the representative cytokines such as TNF-α, IL-1β, IL-6, IL-8, and IL-10 of serum and peritoneal fluid samples. RESULTS Over a 26-months investigation period, 18 patients (sex ratio, male:female=9:9) were eligible for study criteria: n=8 were enrolled in the VAC (m:f=4:4) and n=10 in the ROD group (m:f=5:5). With regard to early postoperative results represented by mortality, there is no significant difference between both patients groups. Despite the relatively low number of cases enrolled in this study, a trend for more severe findings associated with the VAC group could be detected based on MPI score. There was also a trend of higher APACHE II scores in the VAC group from the 7th POD on and, in addition, patients of this group had a longer hospital stay. For patients with persisting infection, there were no relevant differences comparing VAC therapy and ROD. Cytokines released, in particular, at the beginning of the inflammation cascade with proinflammatory characteristics, showed higher values within the peritoneal fluid whereas CrP and PCT were found to be higher within the serum samples. Summary & Conclusion: Comparing data of various local and systemic inflammatory and immune parameters, there were only a few correlations. This may indicate a compartimentation of the inflammatory process within the abdominal cavity. Based on the observed inter-individual variation of this pilot study data, the clinically applicable benefit appears questionable. In this context, a reliable effect of VAC therapy onto reduction of bacterial burden within the abdominal cavity could not clearly be detected.

Abstract
Background Severe complicated intra-abdominal sepsis (SCIAS) has an increasing incidence with mortality rates over 80% in some settings. Mortality typically results from disruption of the gastrointestinal tract, progressive and self-perpetuating bio-mediator generation, systemic inflammation, and multiple organ failure. Principles of treatment include early antibiotic administration and operative source control. A further therapeutic option may be open abdomen (OA) management with active negative peritoneal pressure therapy (ANPPT) to remove inflammatory ascites and ameliorate the systemic damage from SCIAS. Although there is now a biologic rationale for such an intervention as well as non-standardized and erratic clinical utilization, this remains a novel therapy with potential side effects and clinical equipoise. Methods The Closed Or Open after Laparotomy (COOL) study will constitute a prospective randomized controlled trial that will randomly allocate eligible surgical patients intra-operatively to either formal closure of the fascia or use of the OA with application of an ANPTT dressing. Patients will be eligible if they have free uncontained intra-peritoneal contamination and physiologic derangements exemplified by septic shock OR a Predisposition-Infection-Response-Organ Dysfunction Score ≥ 3 or a World-Society-of-Emergency-Surgery-Sepsis-Severity-Score ≥ 8. The primary outcome will be 90-day survival. Secondary outcomes will be logistical, physiologic, safety, bio-mediators, microbiological, quality of life, and health-care costs. Secondary outcomes will include days free of ICU, ventilation, renal replacement therapy, and hospital at 30 days from the index laparotomy. Physiologic secondary outcomes will include changes in intensive care unit illness severity scores after laparotomy. Bio-mediator outcomes for participating centers will involve measurement of interleukin (IL)-6 and IL-10, procalcitonin, activated protein C (APC), high-mobility group box protein-1, complement factors, and mitochondrial DNA. Economic outcomes will comprise standard costing for utilization of health-care resources. Discussion Although facial closure after SCIAS is considered the current standard of care, many reports are suggesting that OA management may improve outcomes in these patients. This trial will be powered to demonstrate a mortality difference in this highly lethal and morbid condition to ensure critically ill patients are receiving the best care possible and not being harmed by inappropriate therapies based on opinion only.

CRITICAL CARE : THE OFFICIAL JOURNAL OF THE CRITICAL CARE FORUM 2015; 19:373. [PMID: 26502877 PMCID: PMC4623902 DOI: 10.1186/s13054-015-1093-4] [Citation(s) in RCA: 40] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/04/2015] [Accepted: 10/07/2015] [Indexed: 12/16/2022]
Abstract
Introduction Inflammatory and protein mediators (cytokine, chemokine, acute phase proteins) play an important, but still not completely understood, role in the morbidity and mortality of intra-abdominal sepsis/injury. We therefore systematically reviewed preclinical and clinical studies of mediators in intra-abdominal sepsis/injury in order to evaluate their ability to: (1) function as diagnostic/prognostic biomarkers; (2) serve as therapeutic targets; and (3) illuminate the pathogenesis mechanisms of sepsis or injury-related organ dysfunction. Methods We searched MEDLINE, PubMed, EMBASE and the Cochrane Library. Two investigators independently reviewed all identified abstracts and selected articles for full-text review. We included original studies assessing mediators in intra-abdominal sepsis/injury. Results Among 2437 citations, we selected 182 studies in the scoping review, including 79 preclinical and 103 clinical studies. Serum procalcitonin and C-reactive protein appear to be useful to rule out infection or monitor therapy; however, the diagnostic and prognostic value of mediators for complications/outcomes of sepsis or injury remains to be established. Peritoneal mediator levels are substantially higher than systemic levels after intra-abdominal infection/trauma. Common limitations of current studies included small sample sizes and lack of uniformity in study design and outcome measures. To date, targeted therapies against mediators remain experimental. Conclusions Whereas preclinical data suggests mediators play a critical role in intra-abdominal sepsis or injury, there is no consensus on the clinical use of mediators in diagnosing or managing intra-abdominal sepsis or injury. Measurement of peritoneal mediators should be further investigated as a more sensitive determinant of intra-abdominal inflammatory response. High-quality clinical trials are needed to better understand the role of inflammatory mediators.

Abstract
BACKGROUND As strategies in acute care surgery focus on damage control to restore physiology, intensivists spanning all disciplines care for an increasing number of patients requiring massive transfusion, temporary abdominal closures, and their sequelae. OBJECTIVE To equip the nonsurgical intensivist with evidence-based management principles for patients with an open abdomen after damage control surgery. DATA SOURCE Search of PubMed database and manual review of bibliographies from selected articles. DATA SYNTHESIS AND CONCLUSIONS Temporary abdominal closure improves outcomes in patients with abdominal compartment syndrome, hemorrhagic shock, and intra-abdominal sepsis but creates new challenges with electrolyte derangement, hypovolemia, malnutrition, enteric fistulas, and loss of abdominal wall domain. Intensive care of such patients mandates attention to resuscitation, sepsis control, and expedient abdominal closure.

Abstract
Although sepsis is a systemic process, the pathophysiological cascade of events may vary from region to region. Abdominal sepsis represents the host’s systemic inflammatory response to bacterial peritonitis. It is associated with significant morbidity and mortality rates, and is the second most common cause of sepsis-related mortality in the intensive care unit. The review focuses on sepsis in the specific setting of severe peritonitis.

Abstract
BACKGROUND Anastomotic dehiscence is the most severe complication of colorectal surgery and its incidence increases in the presence of infection. It has been reported that immune factors or the activity of matrix metalloproteinases (MMP) may mediate the loss of anastomotic strength in the first postoperative days. In this study, we investigated the effects of abdominal sepsis on the MMP and interleukin (IL) gene expression in left colonic anastomoses in rats. MATERIALS AND METHODS Forty rats were divided into two groups of 20 animals according to the presence (group S) or absence (group N) of sepsis induction by cecal ligation and perforation during left colonic anastomosis. Each group was divided into subgroups for euthanasia on the third (N3 and S3) or seventh (N7 and S7) postoperative day (POD). A colonic segment containing anastomosis was removed for analysis of the expression of MMP1a, MMP8, MMP13, IL1β, IL6, IL10, TNFα, and IFNγ genes. RESULTS The anastomoses with abdominal sepsis showed increased MMP1a gene expression and decreased MMP8 gene expression both on the third and seventh POD. There was no change in the expression of MMP13. There was an increase in the expression of IL10 only on the third POD and a negative modulation of IL1β, IFNγ, and IL6 genes on both periods. The TNFα gene expression was negatively modulated on the third POD and became not modulated on the seventh POD. CONCLUSION Abdominal sepsis induced a specific inflammatory pattern with increased MMP1a and IL10 gene expression and negative modulation of MMP8, IL1β, IFNγ, and TNFα gene expression in left colonic anastomoses in rats.

Abstract
Our earlier results demonstrated that clinically relevant concentrations of unconjugated bilirubin (UCB) possessed immunotoxic effects. Whole-body irradiation (WBI) with 1 to 6 Gy leads to acute radiation syndrome, immunosuppression, and makes the host susceptible to infection. Since hyperbilirubinemia has been shown to be associated with several types of cancer, the present studies were undertaken to evaluate the radiomodifying effects of UCB in radiation-exposed mice having elevated levels of UCB. Pretreatment of splenic lymphocytes with UCB (1-50 μM at UCB/BSA ratio <1) augmented radiation-induced DNA strand breaks, MMP loss, calcium release, and apoptosis. Combination treatment of mice with UCB (50mg/kg bw) followed by WBI (2 Gy) 0.5h later, resulted in significantly increased splenic atrophy, bone marrow aplasia, decreased counts of peritoneal exudate cells, and different splenocyte subsets such as CD3+ T, CD4+ T, CD8+ T, CD19+ B, and CD14+ macrophages as compared to either UCB or WBI treatment. Hematological studies showed that WBI-induced lymphopenia, thrombocytopenia, and neutropenia were further aggravated in the combination treatment group. UCB pretreatment of mice potentiated WBI-induced apoptosis and decreased WBI-induced loss of functional response of various immune cells leading to augmentation of immunosuppression and infection susceptibility caused by WBI. In an acute bacterial peritonitis model, UCB pretreatment of mice significantly increased WBI-induced proinflammatory cytokines, nitric oxide, and peritoneal bacterial load resulting in increased infection and death. Studies using the pharmacological inhibitor of p38MAPK demonstrated the involvement of p38MAPK activation in the inflammatory cascade of peritonitis. These findings should prove useful in understanding the potential risk to hyperbilirubinemic patients during radiotherapy and victims of acute radiation exposure in the course of radiation accidents.

Abstract
BACKGROUND Management of the open abdomen is an increasingly common part of surgical practice. The purpose of this review is to examine the scientific background for the use of temporary abdominal closure (TAC) in the open abdomen as a way to modulate the local and systemic inflammatory response, with an emphasis on decompression after abdominal compartment syndrome (ACS). METHODS A review of the relevant English language literature was conducted. Priority was placed on articles published within the last 5 years. RESULTS/CONCLUSION Recent data from our group and others have begun to lay the foundation for the concept of TAC as a method to modulate the local and/or systemic inflammatory response in patients with an open abdomen resulting from ACS.

Peritoneal fluid: a potential mechanism of systemic neutrophil priming in experimental intra-abdominal sepsis. Am J Surg 2011; 203:211-6.

Abstract
BACKGROUND Recent studies suggest that peritoneal fluid (PF) may be an important mediator of inflammation. The aim of this study was to test the hypothesis that PF may drive systemic inflammation in intra-abdominal sepsis by representing a priming agent for neutrophils. METHODS PF was collected 12 hours after the initiation of intra-abdominal sepsis in swine. Naive human neutrophils were primed with PF before treatment with N-formyl-Met-Leu-Phe or phorbol 12-myristate 13-acetate to elucidate receptor-dependent and receptor-independent mechanisms of neutrophil activation. Flow cytometry was used to quantify neutrophil surface adhesion marker expression of integrins and selectins and superoxide anion production. Additionally, proinflammatory cytokines were quantified in PF. RESULTS PF primed neutrophils via receptor-dependent and receptor-independent mechanisms. There were significant increases in the proinflammatory cytokines interleukin-6 and tumor necrosis factor-α in PF correlating with the development of intra-abdominal sepsis. CONCLUSIONS PF represents a priming agent for naive polymorphonuclear cells in intra-abdominal sepsis. This may be secondary to increased levels of proinflammatory cytokines. Strategies to reduce the amount of PF may decrease the systemic inflammatory response by reducing a priming agent for neutrophils.

Abstract
BACKGROUND There is a need for diagnostic biomarkers that can rapidly differentiate dogs with sepsis from dogs with noninfectious forms of systemic inflammatory response syndrome (NSIRS). OBJECTIVES To compare serum NT-pCNP concentrations among dogs with various forms of sepsis, NSIRS, and healthy controls and to evaluate the use of serum NT-pCNP for the diagnosis of various forms of sepsis in dogs. ANIMALS One hundred and twelve dogs including 63 critically ill dogs (sepsis n = 29; NSIRS n = 34) and 49 healthy control dogs. METHODS Prospective clinical investigation. Serum samples were collected for NT-pCNP measurement from dogs with sepsis or NSIRS within 24 hours of intensive care unit admission or at the time of presentation for healthy dogs. Dogs with sepsis were subclassified based on the anatomic region of infection. Serum NT-pCNP concentrations were compared among sepsis, NSIRS and healthy groups as well as among sepsis subgroups. The area under the curve (AUC), sensitivity, and specificity for identifying dogs with sepsis were determined. RESULTS Using a cut-off value of 10.1 pmol/L, AUC, sensitivity, and specificity of NT-pCNP for differentiating dogs with sepsis from dogs with NSIRS or healthy control dogs were 0.71 (95% CI, 0.58-0.85), 65.5% (45.7-82.1%), and 89.2% (80.4-94.9%), respectively. Serum NT-pCNP had poor sensitivity for peritoneal sources of sepsis; AUC [0.92 (0.81-1.0)], sensitivity [94% (71-100%)], and specificity [89% (80-95%)] improved when these dogs were excluded. Serum NT-pCNP concentration was not associated with survival in the sepsis group. CONCLUSIONS AND CLINICAL IMPORTANCE Serum NT-pCNP is a promising diagnostic biomarker for sepsis but is a poor indicator of septic peritonitis.

Peritoneal cytokines predict mortality after surgical treatment of secondary peritonitis in the rat. J Am Coll Surg 2010; 211:263-70.

Abstract
BACKGROUND The study aimed to analyze if peritoneal cytokine levels can predict survival in an experimental model for peritonitis. Early identification of patients most at risk for adverse outcomes would facilitate the decision for aggressive therapy in order to maximally exploit their chance for survival. STUDY DESIGN Peritonitis was induced by intraperitoneal injection of a feces/bacteria mixture in 175 rats. Surgical debridement was performed after 1 hour. Abdominal fluid samples were taken after 24 and 72 hours for the measurement of interleukin (IL)-6, IL-10, and tumor necrosis factor (TNF)-alpha. Surviving animals were sacrificed after 5 days and correlations between cytokine levels and survival were analyzed. RESULTS Altogether, 60 animals died prematurely, 12 before the first sampling of cytokines. So, 48 nonsurvivors and 115 survivors were analyzed. Peritoneal cytokine levels were much higher (p < 0.0001) in nonsurvivors than in survivors. At 24 hours there were strong correlations between cytokine levels, especially between IL-6 and IL-10 (r = 0.93). Peritoneal cytokines at 24 hours also discriminated between animals dying within the next 24 hours and those dying later. A strongly (p < 0.0001) increased mortality was observed if IL-6, IL-10, or TNF-alpha levels exceeded 2, 1, or 0.2 ng/mL, respectively. Receiver operating characteristic curves were promising for all 3, but IL-10 showed the best characteristics, with an area under the curve of 0.94 and 67% sensitivity at 95% specificity, obtained at a cut-off value of 1.26 ng/mL. CONCLUSIONS These data should generate renewed interest to examine the peritoneal cytokines as early markers for adverse outcomes in patients with secondary peritonitis. Possibly, combinations of peritoneal cytokines with other markers can lead to much needed, reliable early prediction of disease severity.

Abstract
BACKGROUND We sought to determine the effect of peritoneal fluid from a novel animal model of abdominal compartment syndrome (ACS) on the proinflammatory status of polymorphonuclear leukocytes (PMNs) and monocytes. We hypothesize that peritoneal fluid is a potential priming and/or activating agent for PMNs/monocytes. METHODS ACS was induced in female Yorkshire swine, and peritoneal fluid was collected at the time of decompressive laparotomy. Naïve PMNs/monocytes were primed and/or activated with peritoneal fluid, phosphatidylcholine (PAF) plus peritoneal fluid, peritoneal fluid plus n-formyl-met-leu-phe (fMLP), and peritoneal fluid plus phorbol 12-myristate 13-acetate (PMA). Activation was determined by surface marker expression of integrins (CD11b an CD18) and selectins (CD62L). Additionally, proinflammatory cytokines in peritoneal fluid were analyzed. RESULTS Peritoneal fluid did not activate PMNs but increased CD11b expression on monocytes. When used as a primer for fMLP- or PMA-induced activation, peritoneal fluid significantly increased CD11b and CD18 expression on PMNs and monocytes. Peritoneal fluid collected at 6 and 12 h post decompressive laparotomy had similar effects. Interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) levels were increased in peritoneal fluid. CONCLUSION Peritoneal fluid represents a primer for PMNs/monocytes and seems to act through receptor-dependent and receptor-independent pathways. Strategies to reduce the amount of peritoneal fluid may decrease the locoregional and systemic inflammatory response by reducing priming and activation of neutrophils/monocytes.

Abstract
Secondary peritonitis continues to cause high morbidity and mortality despite improvements in medical and surgical therapy. This review combines data from published literature, focusing on molecular patterns of inflammation in pathophysiology and prognosis during peritonitis. Orchestration of the innate immune response is essential. To clear the microbial infection, activation and attraction of leukocytes are essential and beneficial, just like the expression of inflammatory cytokines. Exaggeration of these inflammatory systems leads to tissue damage and organ failure. Nonsurvivors have increased proinflammation, complement activation, coagulation, and chemotaxis. In these patients, anti-inflammatory systems are decreased in blood and lungs, whereas the abdominal compartment shows decreased neutrophil activation and decreased or stationary chemokine and cytokine levels. A later down-regulation of proinflammatory mediators with concomitant overexpression of anti-inflammatory mediators leads to immunoparalysis and failure to clear residual bacterial load, resulting in the occurrence of superimposed infections. Thus, in patients with adverse outcome, the inflammatory reaction is no longer contained within the abdomen, and the inflammatory response has shifted to other compartments. For the understanding of the host response to secondary peritonitis, it is essential to realize that the defense systems presumably are expressed differently and, in part, autonomously in different compartments.

Abstract
BACKGROUND Optimal therapy of secondary peritonitis frequently results in the formation of residual abscesses, which bear a substantial mortality and morbidity. This study aims to prove that fibrinolytic therapy with recombinant tissue plasminogen activator (rtPA) can reduce abscess formation after surgical treatment of secondary peritonitis in a rat model, without causing unwanted side effects. MATERIALS AND METHODS Male Wistar rats received an intra-abdominal injection with a suspension of sterile feces, 10(5) cfu Escherichia coli and 10(4) cfu Bacteroides fragilis. Surgical debridement was performed 1 h after inoculation. Animals were randomized into four groups (n = 14 each). Three groups received human rtPA at 1 h (rtPA1); 1 h and 6 h (rtPA2); and 1, 6, and 24 h (rtPA3), respectively. Each dose contained 1.25 mg rtPA. Controls received saline only. Animals were killed after 5 days. RESULTS rtPA treatment reduced abscess formation in surviving animals, depending on number of doses given. Animals in group rtPA3 had no abscesses in contrast to 88% of the controls (mean 3.6 +/- 2.7 abscesses per rat; p < 0.05). In the rtPA1 and rtPA2 group, frequency of abscess formation was 58 and 33%, respectively. Mortality, course of body weight, and bacteremia were not affected by rtPA and neither were peritoneal cell counts and levels of TNF-alpha, IL-1beta, IL-6 and IL-10. No bleeding complications were observed. CONCLUSION rtPA reduces intra-abdominal abscess formation after surgical treatment of generalized peritonitis without increasing mortality or affecting the local inflammatory response.

Abstract
Intra-abdominal abscesses are a potential source of recurrent or residual infection after surgical intervention for secondary peritonitis. The development of therapies requires a model which combines low mortality with the formation of persisting abscesses and which is also suitable to study the local inflammatory response. Male Wistar rats were injected intraperitoneally with a mixture of sterile rat faeces, increasing doses of E. coli (10(4)-10(8) cfu/ml) and a fixed dose of B. Fragilis (10(4) cfu/ml). After one h a laparotomy was performed and the peritoneal cavity was debrided. Blood samples were taken under anaesthesia after 6 and 24 h. Abdominal fluid samples were collected (by laparotomy) after 24 and 72 h. The rats were killed after 5 days and the abdomen was inspected for abscesses. Mortality was 90% in the two groups with the highest doses of E. coli and 30% in those with the two lowest doses. In the latter groups all surviving rats but one showed intraabdominal abscesses and bacteremia was encountered frequently, especially after 24 h in the 10(5) cfu E. coli group. The groups receiving 10(4)-10(6) cfu E. coli showed similar plasma IL-6 concentrations after 6 h which were lowered significantly after 24 h. No circulating TNF-alpha was found. Considerable concentrations of TNF-alpha, IL-6, IL-1beta, and IL-10, were found in the peritoneal fluid after 24 h but no differences were observed between the contro groups and those receiving 10(4)-10(6) cfu E. coli. At 72 h cytokine levels were reduced significantly and remained the highest in the animals dosed with 10(6) cfu E. coli. The present model is suitable to study the mechanisms involved in, and prevention of, intra-abdominal abscess formation after surgical treatment of generalized peritonitis.

Abstract
BACKGROUND This study examines the influence of surgical management (elimination of the infectious focus and abdominal lavage) on survival and the inflammatory response in the various compartments of the body: local (abdomen), systemic (blood) and distant organ (lungs). MATERIALS AND METHODS Peritonitis was established in mice by cecal ligation and puncture (CLP). After 24 h, a group was made in which the infected cecum was resected and the abdominal cavity was lavaged (RES), and another group that received no surgical resection (NoRES). Survival was examined over a period of 96 h. Mice were sacrificed at 24 (sham and CLP), 48 and 72 h after CLP to measure inflammatory parameters. RESULTS Survival was significantly lower is NoRES compared to sham and RES (p = 0.006, p = 0.014, respectively). Intraperitoneal parameters were improved in the RES group compared to sham but results were not significantly different between groups. In plasma, levels of interleukin-6 (IL-6) were decreased in RES (p = 0.048). Accordingly, anti-inflammatory IL-10 in plasma was increased in this group (p = 0.031). In the lung, keratinocyte-derived chemokine (KC) and myeloperoxidase (MPO) was reduced indicating decreased granulocytes accumulation in the lung in the RES group (p = 0.012 and p = 0.004, respectively). CONCLUSIONS In experimental secondary peritonitis surgical management improves survival and attenuates the inflammatory response predominantly in the extra-abdominal compartments. This illustrates the importance of surgery in prevention of multiple organ failure and denotes the compartmentalized character of the inflammatory response. This polymicrobial model with implicated surgical intervention reflects the clinical situation and may be more appropriate to test therapeutic interventions than a model involving only CLP.

Abstract
Gram-negative sepsis due to fecal peritonitis is a hazardous disease with a high percentage having a lethal course. The inflammatory effects are induced by endotoxin release. We performed this study to evaluate the potential of direct intraperitoneal application of an endotoxin inhibitor in a laparoscopic peritonitis model in rats. The human feces specimen was prepared, and a standard fecal specimen (0.5 ml/kg b.w.) was applied via minilaparotomy. The rats were randomized to two studies. First, rats were randomized to three groups to define the survival time: (1) rats without further manipulation; (2) rats with laparoscopic lavage using NaCl; (3) rats with laparoscopic lavage using endotoxin inhibitor. Second, rats underwent the same procedure used in the first part of the study and an additional group with only NaCl lavage without peritonitis was randomized. To evaluate the immunologic or biochemical effects, animals were killed at a standard time of 20 hours until the postmortem examination was established. Interleukins 6 and 10 (IL-6, IL-10), malondialdehyde, and protein carbonyl group levels in plasma and particularly in peritoneal fluid were assayed. The first part of the experiment showed significantly increased survival after endotoxin inhibitor lavage. In the second part, administration of endotoxin inhibitor intraperitoneally caused a significant reduction of IL-6 in the peritoneal fluid, in contrast to that in the other groups. Laparoscopic application of endotoxin inhibitor intraperitoneally thus produced a beneficial effect on survival and reduction of IL-6 in peritoneal fluid. Hence, it is possible to influence the inflammation cascade by causing intraperitoneal endotoxin inhibition.

Abstract
Neutrophil migration to an infectious focus is essential for control and resolution of infection. Early studies demonstrated that the failure of such migration is observed in lethal sepsis induced by cecal ligation and puncture (L-CLP), whereas intense neutrophil migration is seen in sublethal CLP (SL-CLP). In this study, we found that inhibition of synthesis of prostaglandins or leukotriene B4 (LTB4) did not modify the failure of neutrophil migration or the survival rate of L-CLP mice. In addition, pretreatment of L-CLP mice with a platelet activating factor (PAF) receptor antagonist (UK74505), despite not interfering with the failure process, significantly increased (33%) the survival rate of the animals. Inhibitors of prostaglandin synthesis (indomethacin and meloxican) and UK74505 did not modify the neutrophil migration observed in SL-CLP. On the other hand, the blockade of LTB4 synthesis (MK886, a 5-lipoxygenase-activating protein inhibitor) or of its receptors (CP-105,696) resulted in reduced neutrophil migration to the peritoneal cavity in SL-CLP mice (62% and 60%, respectively), a consequent increase in the number of bacteria in the inflammatory focus, and a reduced survival rate of the animals (43% and 38%, respectively). Both SL-CLP and L-CLP animals presented significant levels of LTB4 in the peritoneal exudate (3- and 8-fold higher than sham group, respectively) and these were reduced by the pretreatment of mice with LTB4 inhibitors. In conclusion, our results suggest that LTB4, but not prostaglandins or PAF, is an important chemoattractant involved in neutrophil recruitment to infection sites in SL-CLP, a crucial event in confining the invading pathogens to a restricted area. However, in circumstances in which the infection turns to a lethal sepsis, LTB4 is not involved in the observed failure of neutrophil migration to the infectious focus.

Abstract
The murine D-galactosamine (D-gal) model of tumor necrosis factor alpha (TNF-alpha) hypersensitization was used as an initial tool to investigate the potential contribution of TNF-alpha to lethal intraperitoneal (i.p.) infection with Enterococcus faecalis. D-gal sensitized mice to lethal E. faecalis infection, whereas dexamethasone and neutralizing anti-TNF-alpha antibody protected D-gal-treated, E. faecalis-infected mice, implicating TNF-alpha in the lethal response to E. faecalis infection in D-gal-treated mice. Circulating TNF-alpha was undetectable for at least 8 h following i.p. E. faecalis infection, although low peritoneal levels of TNF-alpha were detected within 3 h, suggesting that localized TNF-alpha production contributed to the lethal response to E. faecalis infection in D-gal-treated mice. Although i.p. E. faecalis infection failed to induce a detectable systemic TNF-alpha response, circulating Interleukin-6 (IL-6) was detected within 3 h of infection. IL-6 was also detected in the peritoneum within an hour of infection, prior to the appearance of peritoneal TNF-alpha. In striking contrast to in vivo results, E. faecalis induced a potent and rapid TNF-alpha response from both mouse peritoneal macrophages and the RAW 264.7 cell line in vitro. This led us to hypothesize that TNF-alpha production in response to E. faecalis infection is suppressed by IL-6 in vivo. In vitro experiments demonstrated a statistically significant, but modest, inhibitory effect of IL-6 on TNF-alpha production by RAW cells stimulated with E. faecalis. Collectively, these data indicate that acute, lethal E. faecalis infection appears to induce an unusual cytokine response that differs in character from that previously described for most other gram-positive and gram-negative bacteria.

Abstract
A significant reduction of the pan T lymphocytes as well as CD4+ and CD8 subsets of cells in the gut mucosa of the septic rats has previously been demonstrated. In contrast, the populations of major histocompatibility complex (MHC) class II-positive cells and macrophages increased. The aim of this study was to evaluate if the immunomodulator Linomide influenced the immune cell distribution in the small intestinal mucosa in sepsis and, furthermore, if these changes coincide with changes in the concentration of tumor necrosis factor-alpha (TNF-alpha) in plasma or ascites. Polymicrobial sepsis was induced in rats by cecal ligation and puncture (CLP). Three different experimental groups were used: CLP, Linomide p.o. + CLP, and Linomide i.p.+ CLP, with adequate controls. Specimens were taken from the small bowel for immunohistologic staining and grading of mucosal injury. The following monoclonal antibodies were used: W3/25, OX8, R73, OX6, and ED1. All slides were examined by one "blinded" examiner. Mucosal injury was graded from 0 to 5. The immunostained tissues were also analyzed by an automatic color-based image system. All controls had a normal appearance of the mucosa (grade 0-1), whereas the septic animals had a median grade of III (II-IV) mucosal injury. Linomide i.p. + CLP decreased mucosal damage to median I (0-IV, P < 0.05). Linomide had no effects on the immune cell distribution in controls. In CLP rats, a significant reduction in both CD4+ and CD8+ T lymphocytes as well as an increased number of macrophages and MHC class II-positive cells was seen in the villi as compared with sham-operated controls (P < 0.05). Linomide attenuated these changes for CD8+ and T lymphocytes and macrophages. Sepsis caused increased concentrations of TNF-alpha in portal blood and ascites 3 h from CLP induction. This increase was attenuated by Linomide.

Abstract
1. Sepsis induced by S. aureus was used to investigate whether neutrophil migration failure to infectious focus correlates with lethality in Gram-positive bacteria-induced sepsis in mice. 2. By contrast with the sub-lethal (SL-group), the lethal (L-group) intraperitoneal inoculum of S. aureus caused failure of neutrophil migration (92% reduction), high CFU in the exudate, bacteremia and impairment of in vitro neutrophil chemotactic activity. 3. Pre-treatments of L-group with adequate doses of aminoguanidine prevented the neutrophil migration failure and improved the survival of the animals (pre-treated: 43%; untreated: 0% survival). Thus, the impairment of neutrophil migration in the L-group appears to be mediated by nitric oxide (NO). 4. The injection of S. aureus SL-inoculum in iNOS deficient (-/-) or aminoguanidine-treated wild-type mice (pre- and post-treatment), which did not present neutrophil migration failure, paradoxically caused severe peritonitis and high mortality. This fact is explainable by the lack of NO dependent microbicidal activity in migrated neutrophils. 5. In conclusion, although the NO microbicidal mechanism is active in neutrophils, the failure of their migration to the infectious focus may be responsible for the severity and outcome of sepsis.

Abstract
We developed two models of sepsis with different degrees of severity, sublethal and lethal sepsis, induced by cecal ligation and puncture. Lethal sepsis induced by cecal ligation and puncture (L-CLP) resulted in failure of neutrophil migration to the infection site and high mortality. Treatment of septic animals with aminoguanidine (AG), a nitric oxide (NO) synthase inhibitor, precluded the failure of neutrophil migration and protected the animals from death. However, cytokine-induced NO synthase (iNOS)-deficient (iNOS(-/-)) mice subjected to L-CLP did not present neutrophil migration failure, but 100% lethality occurred. iNOS(-/-) mice subjected to sublethal sepsis induced by cecal ligation and puncture (SL-CLP) also suffered high mortality despite the occurrence of neutrophil migration. This apparent paradox could be explained by the lack of microbicidal activity in neutrophils of iNOS(-/-) mice present at the infection site due to their inability to produce NO. Notably, SL- and L-CLP iNOS(-/-) mice showed high bacterial numbers in exudates. The inhibition of neutrophil migration by NO is due to inhibition of a neutrophil/endothelium adhesion mechanism, since a reduction in leukocyte rolling, adhesion, and emigration was observed in L-CLP wild-type mice. These responses were prevented by AG treatment and were not observed in the iNOS(-/-) L-CLP group. There was no significant change in L-selectin expression in neutrophils from L-CLP mice. Thus, it seems that the decrease in leukocyte rolling is due to a defect in the expression of adhesion molecules on endothelial surfaces mediated by iNOS-derived NO. In conclusion, the results indicate that despite the importance of NO in neutrophil microbicidal activity, its generation in severe sepsis reduces neutrophil migration by inhibiting leukocyte rolling and their firm adhesion to the endothelium, in effect impairing the migration of leukocytes and consequently their fundamental role in host cell defense mechanisms.

Abstract
BACKGROUND Tumor necrosis factor alpha (TNF-alpha) has been shown to decrease collagen synthesis and increase collagenase activity leading to impaired wound healing. Our hypothesis was that immediate postoperative feeding would decrease TNF-alpha, therefore increasing anastomotic healing in a peritonitis model. METHODS Twelve Sprague-Dawley rats underwent cecal ligation and puncture to induce peritonitis. Six hours after induction of peritonitis an ileocecectomy and ileocolostomy was performed. Group 1 animals (n = 6) had immediate access to food and water, whereas group 2 (n = 6) had free access to water only. At 48 hours, weight loss, nitrogen loss, anastamotic bursting strength (ABS), TNF-alpha, interleukin-6 (IL-6), and IL-10 were measured. RESULTS Weight loss was similar in the two groups. Group 1 rats had a significantly lower mean TNF-alpha level (17.3 +/- 10 versus 17.3 +/- 10 mcg/Dl, P = 0.05). ABS was also significantly higher in group 1 rats when compared with group 2 rats (81 +/- 34 versus 39 +/- 13 mm HG, P = 0.03). CONCLUSIONS These data suggest that immediate postoperative feeding results in a beneficial change in the cytokine profile.

Abstract
The peritoneal cavity contains resident and migratory cell populations, which play crucial roles in the local defensive response against bacterial invasion. Although mononuclear phagocytes predominate in the peritoneal cavity of healthy subjects, recent attention has been focused on mesothelial and dendritic cells. Kinetic analysis of inflammatory mediators has derived from experimental models of peritonitis, but advances in the understanding of the roles of molecules such as lipocortins, PAF, leukotriene B4, PPAR gamma agonists, and chemokines has also been made. Little is known about the peritoneal response to physical trauma in the context of the abdominal compartment syndrome. Studies on the cellular and molecular pathology of intra-abdominal abscesses, peritoneal sclerosis, and other less frequent clinical entities (e.g., tertiary peritonitis) are needed. Biological therapy may contribute to improved clinical management of such diseases.
