Abstract
Hinokitiol is a natural bio-active tropolone derivative with promising antioxidant and anti-inflammatory properties. This study was conducted to evaluate the ameliorative effects of hinokitiol against acute pancreatitis induced by cerulein. Mice were pre-treated with hinokitiol intraperitoneally for 7 days (50 and 100 mg/kg), and on the final day of study, cerulein (6 × 50 μg/kg) was injected every hour for six times. Six hours after the last dose of cerulein, blood was collected from the mice through retro-orbital plexus for biochemical analysis. After blood collection, mice were euthanized and the pancreas was harvested for studying effects on oxidative stress, pro-inflammatory cytokines, immunohistochemistry and histopathology of tissue sections. Hinokitiol treatment significantly reduced edema of the pancreas and reduced the plasma levels of lipase and amylase in mice with cerulein-induced acute pancreatitis. It also attenuated the oxidative and nitrosative stress related damage as evident from the reduced malondialdehyde (MDA) and nitrite levels, which were significantly increased in the mice with acute pancreatitis. Furthermore, hinokitiol administration significantly reduced the pancreatitis-evoked decrease in the activity of catalase, glutathione (GSH) and superoxide dismutase (SOD) in the pancreatic tissue. Pre-treatment with hinokitiol significantly reduced the elevated levels of pro-inflammatory cytokines like interleukin-6 (IL-6), interleukin-1β (IL-1β), tumor necrosis factor-alpha (TNF-α) as well as increased the levels of anti-inflammatory cytokine interleukin-10 (IL-10) in the pancreatic tissue of mice with acute pancreatitis. The immunohistochemical expression of nuclear factor kappa light chain enhancer of activated B cells (NF-κB), cyclooxygenase (COX-2) and TNF-α were significantly decreased by hinokitiol in mice with cerulein-induced acute pancreatitis. In conclusion, the results of the present study demonstrate that hinokitiol has significant potential to prevent cerulein-induced acute pancreatitis.

Abstract
Heart failure is associated with decreased tissue perfusion and increased venous congestion that may result in organ dysfunction. This dysfunction has been investigated extensively for many organs, but data regarding pancreatic (exocrine) dysfunction are scarce. In the present review we will discuss the available data on the mechanisms of pancreatic damage, how heart failure can lead to exocrine dysfunction, and its clinical consequences. We will show that heart failure causes significant impairment of pancreatic exocrine function, particularly in the elderly, which may exacerbate the clinical syndrome of heart failure. In addition, pancreatic exocrine insufficiency may lead to further deterioration of cardiovascular disease and heart failure, thus constituting a true vicious circle. We aim to provide insight into the pathophysiological mechanisms that constitute this reciprocal relation. Finally, novel treatment options for pancreatic dysfunction in heart failure are discussed.

Tricetin Reduces Inflammation and Acinar Cell Injury in Cerulein-Induced Acute Pancreatitis: The Role of Oxidative Stress-Induced DNA Damage Signaling. Biomedicines 2022; 10:biomedicines10061371. [PMID: 35740393 PMCID: PMC9219693 DOI: 10.3390/biomedicines10061371] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2022] [Revised: 06/06/2022] [Accepted: 06/07/2022] [Indexed: 12/29/2022] Open
Abstract
Acute pancreatitis (AP) poses a worldwide challenge due to the growing incidence and its potentially life-threatening course and complications. Specific targeted therapies are not available, prompting the identification of new pathways and novel therapeutic approaches. Flavonoids comprise several groups of biologically active compounds with wide-ranging effects. The flavone compound, tricetin (TCT), has not yet been investigated in detail but sporadic reports indicate diverse biological activities. In the current study, we evaluated the potential protective effects of TCT in AP. TCT (30 μM) protected isolated primary murine acinar cells from the cytotoxic effects of cerulein, a cholecystokinin analog peptide. The protective effects of TCT were observed in a general viability assay (calcein ester hydrolysis), in an apoptosis assay (caspase activity), and in necrosis assays (propidium iodide uptake and lactate dehydrogenase release). The effects of TCT were not related to its potential antioxidant effects, as TCT did not protect against H2O2-induced acinar cell death despite possessing radical scavenging activity. Cerulein-induced expression of IL1β, IL6, and matrix metalloproteinase 2 and activation of nuclear factor-κB (NFκB) were reduced by 30 μM TCT. In vivo experiments confirmed the protective effect of TCT in a mouse model of cerulein-induced AP. TCT suppressed edema formation and apoptosis in the pancreas and reduced lipase and amylase levels in the serum. Moreover, TCT inhibited interleukin-1β (IL1β), interleukin-6 (IL6), and tumor necrosis factor-α (TNFα) expression in the pancreas and reduced the activation of the oxidative DNA damage sensor enzyme poly(ADP-ribose) polymerase-1 (PARP-1). Our data indicate that TCT can be a potential treatment option for AP.

Abstract
This study investigated the patient outcomes, incidence, and predisposing factors of elevated pancreatic enzyme levels after OHCA. We conducted a retrospective cohort study of patients treated with targeted temperature management (TTM) after out-of-hospital cardiac arrest (OHCA). Elevation of pancreatic enzyme levels was defined as serum amylase or lipase levels that were at least three times the upper limit of normal. The factors associated with elevated pancreatic enzyme levels and their association with neurologic outcomes and mortality 28 days after OHCA were analyzed. Among the 355 patients, 166 (46.8%) patients developed elevated pancreatic enzyme levels. In the multivariable analysis (odds ratio, 95% confidence interval), initial shockable rhythm (0.62, 0.39−0.98, p = 0.04), time from collapse to return of spontaneous circulation (1.02, 1.01−1.04, p < 0.001), and history of coronary artery disease (1.7, 1.01−2.87, p = 0.046) were associated with elevated pancreatic enzyme levels. After adjusting for confounding factors, elevated pancreatic enzyme levels were associated with neurologic outcomes (5.44, 3.35−8.83, p < 0.001) and mortality (3.74, 2.39−5.86, p < 0.001). Increased pancreatic enzyme levels are common in patients treated with TTM after OHCA and are associated with unfavorable neurologic outcomes and mortality at 28 days after OHCA.

Abstract
Although coronavirus disease 2019 (COVID-19)-related major health consequences involve the lungs, a growing body of evidence indicates that COVID-19 is not inert to the pancreas either. This review presents a summary of the molecular mechanisms involved in the development of pancreatic dysfunction during the course of COVID-19, the comparison of the effects of non-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on pancreatic function, and a summary of how drugs used in COVID-19 treatment may affect this organ. It appears that diabetes is not only a condition that predisposes a patient to suffer from more severe COVID-19, but it may also develop as a consequence of infection with this virus. Some SARS-CoV-2 inpatients experience acute pancreatitis due to direct infection of the tissue with the virus or due to systemic multiple organ dysfunction syndrome (MODS) accompanied by elevated levels of amylase and lipase. There are also reports that reveal a relationship between the development and treatment of pancreatic cancer and SARS-CoV-2 infection. It has been postulated that evaluation of pancreatic function should be increased in post-COVID-19 patients, both adults and children.

Abstract
A 78-year-old man presented to our hospital with a history of 10kg weight loss within 6 months previously, and general fatigue and fever for 2 and 1 months, respectively. On hospitalization, the patient was diagnosed with polyarteritis nodosa after multiple microaneurysms were observed in the liver, kidney, pancreas, and mesenteries. He achieved remission with the administration of 1,000mg methylprednisolone for 3 days, followed by prednisolone (55mg/day). Steroids were successfully tapered with no re-elevation in inflammation. Two months after the administration of steroids, the patient complained of acute abdominal pain, and developed severe acute pancreatitis. During treatment for pancreatitis, the patient died due to septic shock and disseminated intravascular coagulation. An autopsy revealed necrotizing vasculitis in the intrapancreatic arteries and ischemia of the downstream arterioles resulting in acute pancreatitis.

Association of Platelets and White Blood Cells Subtypes with Trauma Patients' Mortality Outcome in the Intensive Care Unit. Healthcare (Basel) 2021; 9:healthcare9080942.

Abstract
Background: White blood cell (WBC) subtypes have been suggested to reflect patients’ immune-inflammatory status. Furthermore, the derived ratio of platelets and WBC subtypes, including monocyte-to-lymphocyte ratio (MLR), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR), is proposed to be associated with patient outcome. Therefore, this study aimed to identify the association of platelets and white blood cells subtypes with the mortality outcome of trauma patients in the intensive care unit (ICU). Method: The medical information from 2854 adult trauma patients admitted to the ICU between 1 January 2009 and 31 December 2019 were retrospectively retrieved from the Trauma Registry System and classified into two groups: the survivors group (n = 2524) and the death group (n = 330). The levels of monocytes, neutrophils, lymphocytes, platelets, and blood-drawn laboratory data detected upon patient arrival to the emergency room and the derived MLR, NLR, and PLR were calculated. Multivariate logistic regression analysis was used to determine the independent effects of univariate predictive variables on mortality occurrence. Result: The results revealed the patients who died had significantly lower platelet counts (175,842 ± 61,713 vs. 206,890 ± 69,006/μL, p < 0.001) but higher levels of lymphocytes (2458 ± 1940 vs. 1971 ± 1453/μL, p < 0.001) than the surviving patients. However, monocyte and neutrophil levels were not significantly different between the death and survivor groups. Moreover, dead patients had a significantly lower PLR than survivors (124.3 ± 110.3 vs. 150.6 ± 106.5, p < 0.001). However, there was no significant difference in MLR or NLR between the dead patients and the survivors. Multivariate logistic regression revealed that male gender, old age, pre-existing hypertension, coronary artery disease and end-stage renal disease, lower Glasgow Coma Scale (GCS), higher Injury Severity Score (ISS), higher level of lymphocytes and lower level of red blood cells and platelets, longer activated partial thromboplastin time (aPTT), and lower level of PLR were independent risk factors associated with higher odds of trauma patient mortality outcome in the ICU. Conclusion: This study revealed that a higher lymphocyte count, lower platelet count, and a lower PLR were associated with higher risk of death in ICU trauma patients.

Abstract
In acute pancreatitis (AP), pancreatic damage leads to local vascular injury, manifesting as endothelial damage and activation, increased vascular permeability, leukocyte rolling, sticking and transmigration to pancreatic tissue as well as activation of coagulation. Previous studies have shown that pretreatment with heparin or acenocoumarol inhibits the development of AP. The aim of the present study was to check the impact of pretreatment with warfarin, an oral vitamin K antagonist, on the development of ischemia/reperfusion-induced AP in rats. AP was induced by pancreatic ischemia followed by reperfusion of the gland. Warfarin (90, 180 or 270 µg/kg/dose) or vehicle were administered intragastrically once a day for 7 days before induction of AP. The effect of warfarin on the severity of AP was assessed 6 h after pancreatic reperfusion. The assessment included histological, functional, and biochemical analyses. Pretreatment with warfarin given at a dose of 90 or 180 µg/kg/dose increased the international normalized ratio and reduced morphological signs of pancreatic damage such as pancreatic edema, vacuolization of acinar cells, necrosis and the number of hemorrhages. These effects were accompanied by an improvement of pancreatic blood flow and a decrease in serum level amylase, lipase, pro-inflammatory interleukin-1β and plasma level of D-dimer. In contrast, pretreatment with warfarin given at a dose of 270 µg/kg/dose led to an increase in severity of pancreatic damage and biochemical indicators of AP. In addition, this dose of warfarin resulted in deaths in some animals. Pretreatment with low doses of warfarin inhibits the development of AP induced by pancreatic ischemia followed by reperfusion.

J Food Biochem 2019; 44:e13130. [PMID: 31851766 DOI: 10.1111/jfbc.13130] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2019] [Revised: 11/27/2019] [Accepted: 11/28/2019] [Indexed: 12/13/2022]
Abstract
In this study, the aim was to examine the potential protective effects of Myrtus communis subsp. communis leaf ethanol extract (MC) treatment against acute pancreatitis (AP) in rats. Thirty-two rats were grouped as the saline-pretreated control (C), MC-pretreated control (MC), saline-pretreated AP (AP), and MC-pretreated AP (MC + AP) groups. To induce AP, cerulein was administered (50 µg/kg) two times. The rats were given MC for 14 days before cerulein injection. Six hours after the final cerulein injection, the rats were sacrificed. Pancreatic damage was associated with an increase in the serum activity of lipase and amylase, the pancreatic activity of myeloperoxidase, and the pancreatic level of malondialdehyde, interleukin-1β, and interleukin-6. AP also led to a decrease in the pancreatic level of anti-inflammatory interleukin-10 and glutathione. Pretreatment with MC before the induction of AP significantly reduced the pancreatic damage observed during the histological examination as well as reversed the biochemical changes evoked by AP. PRACTICAL APPLICATIONS: Acute pancreatitis is characterized by high mortality (average about 5%; severe cases may reach about 30%). The current treatment for acute pancreatitis is mainly symptomatic. The introduction of herbal drugs may lead to the development of a new strategy in the treatment of this disease. This study revealed that MC reduced pancreatic injury by decreasing pro-inflammatory cytokines, increasing antioxidant capacity and anti-inflammatory cytokine, IL-10. To the authors' knowledge, this research is the first report showing that MC inhibits the development of AP. This observation suggests that MC may be useful in the prevention and the treatment of AP in clinical settings.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) has a poor prognosis, which is mainly due to late diagnosis and profound resistance to treatment. The latter is to a large extent attributed to the tumor stroma that is exceedingly prominent in PDAC and engages in complex interactions with the cancer cells. Hence, relevant preclinical models of PDAC should also include the tumor stroma. We herein describe the establishment and functional validation of an ex vivo organotypic culture of human PDAC that is based on precision-cut tissue slices from surgical specimens and reproducibly recapitulates the complex cellular and acellular composition of PDAC, including its microenvironment. The cancer cells, tumor microenvironment and interspersed remnants of nonneoplastic pancreas contained in these 350 µm thick slices maintained their structural integrity, phenotypic characteristics and functional activity when in culture for at least 4 days. In particular, tumor cell proliferation persisted and the grade of differentiation and morphological phenotype remained unaltered. Cultured tissue slices were metabolically active and responsive to rapamycin, an mTOR inhibitor. This culture system is to date the closest surrogate to the parent carcinoma and harbors great potential as a drug sensitivity testing system for the personalized treatment of PDAC.

Abstract
Elevated serum pancreatic enzymes have been described among patients with small bowel obstruction (SBO) initially misdiagnosed as having pancreatitis. We studied whether serum lipase elevation carries prognostic value in patients with SBO. Patients with SBO and at least one serum lipase level measured were included. Demographic, laboratory, and imaging information, as well as need for surgery or intensive care unit and mortality, were evaluated. Of 344 patients, 38 (11%) had elevated serum lipase levels. Patients with radiographic diagnosis of pancreatitis were excluded. Patients with elevated lipase had significantly higher levels of creatinine and lactic acid levels, length of stay, need for intensive care monitoring, and death than patients with normal lipase levels. The need for surgical intervention was not significantly different between the two groups. Logistic regression analysis showed elevated serum lipase and serum creatinine >1.5 mg/dL as predictors for mortality. We conclude that, in SBO, elevated serum lipase is a risk factor for higher serum creatinine and lactate, use of intensive care unit, and mortality. The strength of this association justifies studying it prospectively.

Abstract
AIM Coagulation disorders may develop in association with severe acute pancreatitis (AP). Plasma thrombin-antithrombin III complex (TAT) levels are one of the principal markers of coagulation disorder. The purpose of this study was to evaluate TAT and other hemostatic parameters in patients with AP and to examine whether or not these parameters indicate the severity of AP. METHOD Forty-six patients with AP (14 severe, 32 non-severe) and a 30-member healthy control group were recruited. The severity of AP was determined using the revised Atlanta classification. ELISA was used to measure patients' plasma TAT levels. RESULTS The TAT levels of AP patients at presentation were higher than those of the control group (p = 0.005). The plasma TAT levels of patients with severe AP were also significantly higher than those of patients with non-severe AP (p = 0.05) and of the control group (p < 0.001). The general accuracy, sensitivity and specificity of TAT levels in predicting the severity of AP were 77.4, 77.8, and 77.3% respectively. CONCLUSION The coagulation cascade was activated in the AP patients in our study, and this was shown to become more pronounced as severity of the disease increased. Plasma TAT levels at the time of presentation in patients with AP can be used as a marker for predicting the severity of the disease.

Abstract
Ghrelin was shown to exhibit protective and therapeutic effect in the gut. Aim of the study was to investigate the role of sensory nerves (SN) in the protective effect of ghrelin in acute pancreatitis (AP). Studies were performed on male Wistar rats or isolated pancreatic acinar cells. After capsaicin deactivation of sensory nerves (CDSN) or treatment with saline, rats were pretreated intraperitoneally with ghrelin or saline. In those rats, AP was induced by cerulein or pancreases were used for isolation of pancreatic acinar cells. Pancreatic acinar cells were incubated in cerulein-free or cerulein containing solution. In rats with intact SN, pretreatment with ghrelin led to a reversal of the cerulein-induced increase in pancreatic weight, plasma activity of lipase and plasma concentration of tumor necrosis factor-α (TNF-α). These effects were associated with an increase in plasma interleukin-4 concentration and reduction in histological signs of pancreatic damage. CDSN tended to increase the severity of AP and abolished the protective effect of ghrelin. Exposure of pancreatic acinar cells to cerulein led to increase in cellular expression of mRNA for TNF-α and cellular synthesis of this cytokine. Pretreatment with ghrelin reduced this alteration, but this effect was only observed in acinar cells obtained from rats with intact SN. Moreover, CDSN inhibited the cerulein- and ghrelin-induced increase in gene expression and synthesis of heat shock protein 70 (HSP70) in those cells. Ghrelin exhibits the protective effect in cerulein-induced AP on the organ and pancreatic acinar cell level. Sensory nerves ablation abolishes this effect.

Abstract
Histones are intra-nuclear cationic proteins that are present in all eukaryotic cells and are highly conserved across species. Within the nucleus, they provide structural stability to chromatin and regulate gene expression. Histone may be released into the extracellular space in three forms: freely, as a DNA-bound nucleosome or as part of neutrophil extracellular traps, and all three can be detected in serum after significant cellular death such as sepsis, trauma, ischaemia/reperfusion injury and autoimmune disease. Once in the extracellular space, histones act as damage-associated molecular pattern proteins, activating the immune system and causing further cytotoxicity. They interact with Toll-like receptors (TLRs), complement and the phospholipids of cell membranes inducing endothelial and epithelial cytotoxicity, TLR2/TLR4/TLR9 activation and pro-inflammatory cytokine/chemokine release via MyD88, NFκB and NLRP3 inflammasome-dependent pathways. Drugs that block the release of histone, neutralise circulating histone or block histone signal transduction provide significant protection from mortality in animal models of acute organ injury but warrant further research to inform future clinical applications.

Abstract
Intravascular activation of coagulation is observed in acute pancreatitis and is related to the severity of this inflammation. The aim of our study was to evaluate the impact of acenocoumarol therapy on the course of acute pancreatitis induced in male rats by pancreatic ischemia followed by reperfusion. Acenocoumarol at a dose of 50, 100, or 150 µg/kg/dose was administered intragastrically once a day, starting the first dose 24 h after the initiation of pancreatic reperfusion. Results: Histological examination showed that treatment with acenocoumarol reduces pancreatic edema, necrosis, and hemorrhages in rats with pancreatitis. Moreover, the administration of acenocoumarol decreased pancreatic inflammatory infiltration and vacuolization of pancreatic acinar cells. These findings were accompanied with a reduction in the serum activity of lipase and amylase, concentration of interleukin-1β, and plasma d-Dimer concentration. Moreover, the administration of acenocoumarol improved pancreatic blood flow and pancreatic DNA synthesis. Acenocoumarol given at a dose of 150 µg/kg/dose was the most effective in the treatment of early phase acute pancreatitis. However later, acenocoumarol given at the highest dose failed to exhibit any therapeutic effect; whereas lower doses of acenocoumarol were still effective in the treatment of acute pancreatitis. Conclusion: Treatment with acenocoumarol accelerates the recovery of ischemia/reperfusion-induced acute pancreatitis in rats.

Abstract
Acute pancreatitis (AP) is an inflammatory disease with varied severity, ranging from mild local inflammation to severe systemic involvement resulting in substantial mortality. Early pathologic events in AP, both local and systemic, are associated with vascular derangements, including endothelial activation and injury, dysregulation of vasomotor tone, increased vascular permeability, increased leukocyte migration to tissues, and activation of coagulation. The purpose of the review was to summarize current evidence regarding the interplay between inflammation, coagulation and endothelial dysfunction in the early phase of AP. Practical aspects were emphasized: (1) we summarized available data on diagnostic usefulness of the markers of endothelial dysfunction and activated coagulation in early prediction of severe AP; (2) we reviewed in detail the results of experimental studies and clinical trials targeting coagulation-inflammation interactions in severe AP. Among laboratory tests, d-dimer and angiopoietin-2 measurements seem the most useful in early prediction of severe AP. Although most clinical trials evaluating anticoagulants in treatment of severe AP did not show benefits, they also did not show significantly increased bleeding risk. Promising results of human trials were published for low molecular weight heparin treatment. Several anticoagulants that proved beneficial in animal experiments are thus worth testing in patients.

Abstract
Coagulation is recognized as a key player in inflammatory and autoimmune diseases. The aim of the current research was to examine the effect of pretreatment with acenocoumarol on the development of acute pancreatitis (AP) evoked by cerulein. Methods: AP was induced in rats by cerulein administered intraperitoneally. Acenocoumarol (50, 100 or 150 µg/kg/dose/day) or saline were given once daily for seven days before AP induction. Results: In rats with AP, pretreatment with acenocoumarol administered at the dose of 50 or 100 µg/kg/dose/day improved pancreatic histology, reducing the degree of edema and inflammatory infiltration, and vacuolization of acinar cells. Moreover, pretreatment with acenocoumarol given at the dose of 50 or 100 µg/kg/dose/day reduced the AP-evoked increase in pancreatic weight, serum activity of amylase and lipase, and serum concentration of pro-inflammatory interleukin-1β, as well as ameliorated pancreatic DNA synthesis and pancreatic blood flow. In contrast, acenocoumarol given at the dose of 150 μg/kg/dose did not exhibit any protective effect against cerulein-induced pancreatitis. Conclusion: Low doses of acenocoumarol, given before induction of AP by cerulein, inhibit the development of that inflammation.

Abstract
OBJECTIVES Ischemic tissue injury contributes to significant morbidity and mortality and is implicated in a range of pathologic conditions, including but not limited to myocardial infarction, ischemic stroke, and acute kidney injury. The associated reperfusion phase is responsible for the activation of the innate and adaptive immune system, further accentuating inflammation. Adenosine triphosphate molecule has been implicated in various ischemic conditions, including stroke and myocardial infarction. STUDY SELECTION Adenosine triphosphate is a well-defined intracellular energy transfer and is commonly referred to as the body's "energy currency." However, Laboratory studies have demonstrated that extracellular adenosine triphosphate has the ability to initiate inflammation and is therefore referred to as a damage-associated molecular pattern. Purinergic receptors-dependent signaling, proinflammatory cytokine release, increased Ca influx into cells, and subsequent apoptosis have been shown to form a common underlying extracellular adenosine triphosphate molecular mechanism in ischemic organ injury. CONCLUSIONS In this review, we aim to discuss the molecular mechanisms behind adenosine triphosphate-mediated ischemic tissue injury and evaluate the role of extracellular adenosine triphosphate in ischemic injury in specific organs, in order to provide a greater understanding of the pathophysiology of this complex process. We also appraise potential future therapeutic strategies to limit damage in various organs, including the heart, brain, kidneys, and lungs.

Abstract
UNLABELLED Obestatin, as ghrelin, has been originally extracted from the stomach, which remains its major source. Previous studies have shown that administration of obestatin exhibits protective and healing-promoting effects in several organs, including the stomach and kidney. In pancreas, pretreatment with obestatin inhibits the development of cerulein-induced acute pancreatitis and promotes survival of pancreatic beta cells and human islets. The aim of the present study was to check the universality of protective effect of obestatin in the pancreas. For this reason we investigated the influence of obestatin administration on the development of ischemia/reperfusion-induced pancreatitis. Acute pancreatitis was induced by pancreatic ischemia followed by reperfusion of the gland. Obestatin (4, 8 or 16 nmol/kg/dose) was administered intraperitoneally twice: 0.5h before exposure to ischemia, and 3h after the first injection. The effect of obestatin on the course of necrotizing pancreatitis was assessed after 6-h reperfusion, and included histological, functional, and biochemical analyses. Treatment with obestatin reduced morphological signs of pancreatic damage including edema, vacuolization of acinar cells, hemorrhages, acinar necrosis, and leukocyte infiltration of the gland. These effects were accompanied by an improvement of pancreatic DNA synthesis and superoxide dismutase activity, and a decrease in serum level of lipase and pro-inflammatory interleukin-1β. Moreover pretreatment with obestatin reduced myeloperoxidase activity and malondialdehyde concentration in pancreatic tissue of rats with acute pancreatitis. CONCLUSIONS Administration of obestatin inhibits the development of ischemia/reperfusion-induced acute pancreatitis. This observation, taken together with previous findings that obestatin protects the pancreas against cerulein-induced pancreatitis, indicates that protective effect of obestatin in the pancreas is universal and independent of the primary cause of acute pancreatitis.

[PMID: 25586363 PMCID: PMC4858084 DOI: 10.1111/jvim.12521] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2014] [Revised: 10/15/2014] [Accepted: 11/11/2014] [Indexed: 11/27/2022] Open
Abstract
BACKGROUND Chronic mitral valvular insufficiency (CMVI) in dogs is very common and might cause clinical signs of congestion and poor tissue perfusion. HYPOTHESIS Poor tissue perfusion from CMVI causes pancreatitis in dogs, as indicated by serum pancreatic lipase concentrations. ANIMALS Sixty-two client-owned dogs consisting of 40 dogs with different stages of heart failure from CMVI and 22 age-matched healthy dogs, based on full cardiac exam and routine laboratory tests. METHODS Prospective, controlled, observational study. Serum canine pancreatic lipase immunoreactivity (cPLI) concentrations were determined by quantitative cPLI test in healthy and CMVI groups. RESULTS Serum cPLI concentrations were 54.0 μg/L (IQR: 38.0-78.8 μg/L) in control, 55.0 μg/L (IQR: 38.3-88.8 μg/L) in ISACHC I, 115.0 μg/L (IQR: 45.0-179.0 μg/L) in ISACHC II and 223.0 μg/L (IQR: 119.5-817.5 μg/L) in ISACHC III. Close correlation to serum cPLI concentration was found in the left atrial to aorta (LA/Ao) ratio (r = 0.597; P = .000) and the severity of heart failure (r = 0.530; P = .000). CONCLUSIONS AND CLINICAL IMPORTANCE This study found CMVI is associated with pancreatic injury in congestive heart failure caused by CMVI. Therefore, periodic monitoring on cPLI could be useful in monitoring dogs in heart failure.

Abstract
BACKGROUND Pancreatic damage in critically ill patients is associated with the progressive failure of multiple organs, but little is known about its clinical characteristics. At present, no guidelines are available for the diagnosis and management of pancreatic damage. This study was undertaken to analyze the clinical and pathologic characteristics of pancreatic necrosis in critically ill children, and to find some biological markers of pancreatic damage or pancreatic necrosis. METHODS We retrospectively reviewed the clinical data, laboratory results, and autopsy findings of 25 children, who were admitted to Hunan Children's Hospital, China from 2003 to 2009, and died of multiple organ failure. The autopsy revealed pancreatic necrosis in 5 children, in whom sectional or gross autopsy was performed. RESULTS The 5 children had acute onset and a fever. Two children had abdominal pain and 2 had abdominal bulging, flatulence and gastrointestinal bleeding. Four children had abnormal liver function, characterized by decreased albumin and 3 children had elevated level of C-reactive protein (CRP). B-ultrasonography revealed abnormal acoustic image of the pancreas in all children, and autopsy confirmed pancreatic necrosis, which may be associated with the damage of the adrenal gland, liver, lung, heart, spleen, kidney, intestine, thymus, mediastinal and mesenteric lymph nodes and other organs. Children 1 and 2 died of acute hemorrhagic necrotizing pancreatitis (AHNP); children 3-5 died of multiple organ dysfunction syndrome (MODS) due to pancreatic necrosis. CONCLUSION Pancreatic damage or pancreatic necrosis in critically ill children is characterized by acute onset, severity, short course, multiple organ damage or failure. It may be asymptomatic in early stage, and easy to be ignored.

Abstract
OBJECTIVE To determine the influence of allopurinol and nimesulide in the protection of the pancreas from acute ischemia-reperfusion (I/R) injury. MATERIALS AND METHODS A total of 30 rabbits were divided into 3 groups, group A: acute I/R only; group B: allopurinol (30 mg/kg) was administered intravenously 10 minutes before ischemia; group C: nimesulide (50 mg/kg) was given intraperitoneally 20 minutes before ischemia. Neopterin and superoxide dismutase (SOD) levels were examined. Pancreatic biopsies were obtained for electron microscopy study. RESULTS The mean neopterin concentrations in group A are 3.56 ± 3.41, 7.74 ± 3.59, and 8.94 ± 2.86 ng/mL, respectively, in the stabilization, ischemia, and reperfusion phases; group B: 3.40 ± 3.03, 7.45 ± 8.89, and 10.64 ± 7.47 ng/mL; and group C: 3.41 ± 2.71, 5.67 ± 2.76, and 4.34 ± 2.87 ng/mL. The mean SOD concentrations in group A are 4.25 ± 1.79, 4.48 ± 1.60, and 5.57 ± 1.15 ng/mL; group B: 4.32 ± 0.81, 5.08 ± 1.10, and 4.45 ± 1.31 ng/mL; and group C: 4.10 ± 0.99, 5.23 ± 1.60, and 3.72 ± 1.30 ng/mL. Histopathology showed the least deterioration in group C. CONCLUSION Nimesulide is more efficient than allopurinol in protecting pancreas from acute I/R injury.

Abstract
PURPOSE The aim of this study was to assess renal or abdominal visceral complications after open aortic surgery (OAS) requiring supra-renal aortic cross clamping (SRACC). METHODS We retrospectively reviewed the medical records of 66 patients who underwent SRACC. Among them, 17 followed supra-celiac aortic cross clamping (SCACC) procedure, 42 supra-renal, and 7 inter-renal aorta. Postoperative renal, hepatic or pancreatic complications were investigated by reviewing levels of serum creatinine and hepatic and pancreatic enzymes. Preoperative clinical and operative variables were analyzed to determine risk factors for postoperative renal insufficiency (PORI). RESULTS Indications for SRACC were 25 juxta-renal aortic occlusion and 41 aortic aneurysms (24 juxta-renal, 12 supra-renal and 5 type IV thoraco-abdominal). The mean duration of renal ischemic time (RIT) was 30.1 ± 22.2 minutes (range, 3 to 120 minutes). PORI developed in 21% of patients, including four patients requiring hemodialysis (HD). However, chronic HD was required for only one patient (1.5%) who had preoperative renal insufficiency. RIT ≥ 25 minutes and SCACC were significant risk factors for PORI development by univariate analysis, but not by multivariate analysis. Serum pancreatic and hepatic enzyme was elevated in 41% and 53% of the 17 patients who underwent SCACC, respectively. CONCLUSION Though postoperative renal or abdominal visceral complications developed often after SRACC, we found that most of those complications resolved spontaneously unless there was preexisting renal disease or the aortic clamping time was exceptionally long.

Abstract
Acute pancreatitis and thrombotic microangiopathy is an established association: but which is the cause, which is the consequence? Thanks to two case reports and a literature review, we put to light an unequivocal link. Indeed, thrombotic microangiopathy may be responsible for ischemic pancreatitis. On the other hand, acute pancreatitis, whatever its cause, may trigger thrombotic microangiopathy. In either case, an anti-ADAMTS-13 antibody can be detected: its research is mandatory.

Abstract
BACKGROUND Hyperamylasemia can be observed anecdotally during the course of severe sepsis or septic shock. This study aimed to investigate the possibility of pancreatic involvement in patients with septic shock using serum pancreatic enzyme determinations and imaging techniques in 21 consecutive patients with septic shock and 21 healthy subjects as controls. METHODS The serum activity of pancreatic amylase and lipase was assayed initially in all subjects and 24 and 48 hours after the initial observation in the 21 patients with septic shock. All patients also underwent radiological examination to detect pancreatic abnormalities. RESULTS The serum activity of pancreatic amylase was significantly higher in the 21 patients with septic shock than in the 21 control subjects during the study period, while the serum activity of lipase was similar to that of the control subjects. Amylase and lipase serum activity did not significantly changed throughout the study period in the 21 patients with septic shock. None of the patients with pancreatic hyperenzymemia had clinical signs or morphological alterations compatible with acute pancreatitis. CONCLUSION The presence of pancreatic hyperenzymemia in septic shock patients is not a biochemical manifestation of acute pancreatic damage, and the management of these patients should be dependent on the clinical situation and not merely the biochemical results.

Abstract
Elevated levels of serum pancreatic enzymes are frequently observed in hemodialysis (HD) patients. The complex hemodynamic, biochemical, and physiological alterations in uremia were speculated to cause excessive release of pancreatic enzymes beyond decreased renal clearance. However, hemodynamic factors are seldom explored in this aspect. We performed the study to evaluate the association between intradialytic hemodynamic change and elevated serum pancreatic amylase (SPA). Eighty-three prevalent HD patients without any clinical evidence of acute pancreatitis underwent pre-HD and post-HD blood sampling for serum pancreatic enzyme levels. Demographic, biochemical, and hematological data were collected from patient record review. Hemodialysis information including intradialytic blood pressure changes and ultrafiltration (UF) amount were collected and averaged for 1 month before the blood sampling day. Patients with elevated SPA during the HD session had greater mean systolic blood pressure and mean arterial pressure reduction, greater UF volume, greater pre-HD blood urea nitrogen and serum creatinine, higher serum phosphorus, lower pre-HD serum total CO2, and lower left ventricle ejection fraction (LVEF). Using multivariate linear and logistic regression analysis, the independent predictors of elevated SPA were determined to be mean arterial pressure reduction during HD, mean UF amount, pre-HD serum total CO2, and LVEF. Greater blood pressure reduction during HD, greater UF volume, lower pre-HD serum total CO2, and lower LVEF were significantly associated with elevated SPA during HD. This suggests that hemodynamic factors contribute to elevated serum pancreatic enzymes in HD patients.

Abstract
BACKGROUND Intraluminal pancreatic enzymes have been shown in animal models to be associated with multiple organ failure after hemorrhagic shock, independent of pancreatitis. The translocation of these enzymes into the circulation may serve as a marker of hemorrhagic shock-induced gut ischemia in critically injured trauma patients. We hypothesized that serum amylase and lipase would be significantly elevated in patients presenting in hemorrhagic shock and in those who develop organ failure. METHODS : Review of a prospective database at a level-1 trauma center from 2000 to 2005. Two thousand seven hundred eleven critically injured trauma patients without pancreatic injuries were evaluated for shock (systolic pressure <90 mm Hg in the emergency department), massive transfusion (10 units of packed red blood cells within the first 24 hours), and organ failure (standard criteria for acute pulmonary, cardiovascular, renal, and hepatic system failure were used). Serum levels >2 times the upper limit of normal for amylase (30-130 U/L) and lipase (7-60 U/L) were defined as elevated. Univariate analyses were performed with the Pearson's chi, and binary logistic regression was used to determine significant risk factors for organ failure. Results with a p value <0.05 were considered significant and are reported. RESULTS : Patients with elevated amylase (n = 481, 18%) were more likely to present in shock (16% vs. 8%), require massive transfusion (19% vs. 9%), develop organ failure (34% vs. 16%), and die (23% vs. 13%). Patients with elevated lipase (n = 288, 11%) were more likely to require massive transfusion (18% vs. 10%) and develop organ failure (43% vs. 16%). Independent predictors of organ failure were age (odds ratio [OR] = 1.016), Injury Severity Score (OR = 1.02), massive transfusion (OR = 3.1), elevated amylase (OR = 1.9), and elevated lipase (OR = 3.2). Elevated amylase was also an independent predictor of mortality (OR = 1.3). CONCLUSIONS : Serum levels of pancreatic enzymes are elevated in patients who present in shock or require a massive transfusion and are independent predictors of organ failure. Whether these elevations are caused by ischemic pancreatitis or the translocation of intraluminal enteric pancreatic enzymes is uncertain and future studies are needed. Trauma patients with elevated pancreatic enzymes in the absence of a pancreatic injury have an increased risk of morbidity and mortality.

Abstract
BACKGROUND Oxidants (and their generator, xanthine oxidase [XO]) play a role in inducing acute lung injury (ALI) expressed both structurally and functionally. Such damage has recently been demonstrated in the presence of pancreas ischemia-reperfusion (IR). We now investigated whether methylene blue (MB), a clinically used coloring agent and antioxidant in itself, protected the lung exposed to pancreas IR. MATERIALS AND METHODS Isolated pancreata (eight replicates/group) were (1) continuously perfused (controls), (2) made ischemic (IR-0) for 40 min and reperfused without treatment, (3) organs procured from allopurinol-treated rats made ischemic and reperfused with allopurinol, and (4) made ischemic and treated upon reperfusion with three different doses of MB contained in the perfusate. All perfusate solutions were directed into the isolated lungs' circulation whereby they were perfused for 60 min. RESULTS Pancreas injury was documented in all IR organs by abnormally high reperfusion pressure, wet-to-dry ratio, amylase and lipase concentrations, and abnormal XO activity and reduced glutathione in the circulation. Lungs paired with IR-0 pancreata developed approximately 60% increase in ventilatory plateau pressure and final PO(2)/FiO(2) decrease by 35%. Their weight during reperfusion and bronchoalveolar lavage (BAL) volume and contents increased 1.5-2.5 times the normal values; XO and reduced glutathione values were abnormal both in the BAL and in the lung tissues. Lungs exposed to IR effluents containing allopurinol or 68 microM MB were minimally damaged, whereas perfusion solutions containing 42 or 128 microM MB were ineffective in preventing lung injury. CONCLUSIONS Ex vivo pancreas IR-induced ALI is preventable by MB, although at a narrow dose range.

Abstract
Oxidants and their generator, xanthine oxidase (XO), play a major role in the damaging of the structural and functional integrity of the lung. Such damage has been recently demonstrated in the presence of pancreas ischemia-reperfusion (IR). We investigated whether mannitol, a clinically used agent and antioxidant, prevented lung damage after pancreas IR. Rats (n = 48) were anesthetized, after which each pancreas was isolated and perfused (controls), or made ischemic (IR) for 40 min, or made ischemic and treated upon reperfusion with four different doses of mannitol administered in the perfusate (8 replicates/group). Ischemia was followed by in-series 15-min pancreas plus normal isolated lung reperfusion. Isolated lungs were subsequently perfused for 45 min with the 15-min accumulated effluents. Pancreas injury occurred in all IR organs as demonstrated by abnormal reperfusion pressure, the wet-to-dry ratio, amylase and lipase leakage into the circulation, and XO activity and reduced glutathione (GSH) pool in the tissues. Pulmonary plateau pressure increased by 80%, and final PO(2)/FiO(2) decreased by 28% in the IR-untreated paired lungs. Bronchoalveolar lavage volume increased by 50% and 2- to 8-fold increase in their contained XO and GSH were recorded as well. The above indices of injury in lungs perfused with 0.77 mM mannitol were the least detected, compared with negligible efficacy of other (0.55 < 0.22 < 1.1 mM) dosages. Amylase and lipase did not contribute to lung injury. Ex vivo acute pancreatitis induces acute lung injury via oxidants/antioxidants imbalance, which is preventable by mannitol.

Abstract
PURPOSE OF REVIEW To learn about the prevalence, pathophysiology, and treatment of exocrine pancreatic involvement in critically ill patients. RECENT FINDINGS Elevations in the levels of pancreatic enzymes are observed in up to 80% of intensive care patients. Most of these patients do not develop clinically relevant pancreatitis. However, elevations in enzyme levels do represent pancreatic damage with a risk of complications. Different factors have been discussed, which may contribute to pancreatic damage in critically ill patients. These include splanchnic hypoperfusion during shock or major surgery, bacterial translocation, elevated triglyceride levels, development of biliary sluge, and biliary pancreatitis, as well as several drugs. Imaging procedures and inflammatory markers help to identify relevant disease. Several therapeutic options have been discussed recently with a focus on early enteral nutrition. SUMMARY Pancreatic damage is frequently observed in critically ill patients. Although in most of these patients, this is without major clinical consequences, some patients develop relevant pancreatitis, which contributes to morbidity and mortality. Risk factors have been identified and therapeutic strategies have been changed.

Abstract
Thrombotic thrombocytopenic purpura (TTP) is a severe multisystemic microvascular disease defined by the association of hemolytic anemia, thrombocytopenia, acute renal failure, fever, and neurological disorders. The pathophysiology has recently been elucidated by the discovery of a von Willebrand factor-cleaving protease (ADAMTS13) deficiency involved in platelet aggregation and ischemia. The association between TTP and acute pancreatitis (AP) has rarely been reported, described either as a cause or a consequence. The role of ADAMTS13 during AP is still unknown. We describe the case of a 41-year-old woman who developed a TTP, with decreased ADAMTS13 activity, associated with severe AP. Published cases of thrombotic microangiopathy associated with AP are reviewed. The pathophysiology, management, prognostic factors, and rationale for treatment are discussed. AP should be sought in patients with TTP presenting with abdominal pain. On the other hand, TTP should be considered in patients with AP and thrombocytopenia.

Abstract
BACKGROUND The aim of this study was to investigate pancreatic injury after 45 min of thoracoabdominal aortic occlusion in a porcine model. METHODS Twenty-four pigs were used. Six pigs underwent sham operation and 18 intravascular balloon thoracoabdominal aortic occlusions for 45 min. The animals were randomly killed at 12, 48 and 120 h after reperfusion. After killing, all pancreata were examined macroscopically for any signs of acute pancreatitis, whereas gland specimens were harvested for histological study to evaluate pancreatic injury (haematoxylin and eosin staining) and acinar cell apoptosis (Terminal deoxynucleotidyl transferase mediated dUTP Nick-End Labelling staining). RESULTS Pancreatic injury severity score was mildly increased in terms of oedematous features at 12 h after reperfusion, but normalized to sham levels by the second day and thereafter. Necrotic injury was not statistically significant at any time point. Acinar cell apoptotic index was mildly increased at 12 and 48 h, but showed a tendency to decrease towards sham levels by the fifth day. One animal developed acute pancreatitis. CONCLUSION Acute pancreatitis is unlikely to occur after 45 min of thoracoabdominal aortic occlusion. However, an early, mild oedematous and apoptotic injury that occurs subclinically seems to be a constant event. This injury might have clinical significance when combined with pre-existent pancreatic pathologies.

Abstract
BACKGROUND Acute pancreatitis can lead to increased pulmonary vascular permeability and respiratory failure. Oxidants (and their generator, xanthine oxidase (XO)) play an important role in injuring the structural integrity of the pulmonary epithelium and endothelium, but their importance in the induction of acute lung injury following pancreas ischaemia-reperfusion (IR) has not been defined. MATERIALS AND METHODS Rats (n = 48) received a regular or a tungsten (oxidoreductase inhibitor)-enriched diet for 14 days. Their isolated pancreases were then either perfused (controls) or made ischaemic (IR) for 40 min (12 replicates/group). This was followed by in-series pancreas plus normal isolated lung reperfusion for 15 min. Lungs only were subsequently perfused with the 15-min accumulated pancreas effluents for 45 min. RESULTS Injury was induced in all IR pancreases as expressed by reperfusion pressure, wet-to-dry ratio and amylase and lipase concentrations. Tissue XO activity was high and reduced glutathione pool was low in the tungsten-free IR pancreases. Pulmonary plateau pressure increased by 46% and final PO(2)/FiO(2) decreased by 24%. Capillary pressure and weight rose two- to fourfold in lungs paired with IR non-treated pancreases. Twofold increases in bronchoalveolar lavage volume and contents, including XO, were also recorded in this group of lungs. Lungs exposed to tungsten-treated ischaemic pancreas effluents were minimally damaged and tissue XO content was low compared to controls. CONCLUSIONS Ex-vivo acute pancreatitis induces acute lung injury via oxidants/antioxidants misbalance, which may be prevented by attenuating pancreas oxidative stress.

Abstract
OBJECTIVE There is a paucity of data regarding gastrointestinal (GI) complications after descending thoracic and thoracoabdominal aortic (DTA/TAA) surgical repairs. We examined our 14-year experience with these repairs to determine the incidence, outcomes, and risk factors for postoperative GI complications. METHODS Between February 1991 and February 2005, we repaired 1,159 DTA/TAA. Data were prospectively collected. The mean patient age was 68 years and 36% were women. Complications were classified as biliary disease, hepatic dysfunction, pancreatitis, GI bleeding, peptic ulcer disease, bowel ischemia, and ileus. Risk factors for the occurrence of GI complications were ascertained by univariate and multivariable analysis. RESULTS Of the 1,159 patients, 81 had 109 GI complications, for a 7% incidence. The mortality associated with GI complications was 39.5% compared with 13.5% (P < .0001) in patients without GI complications. The incidences of complications were bowel ischemia, 2.5% with 62% mortality; biliary disease, 0.3% with 75% mortality; hepatic dysfunction, 1.6% with 38% mortality; acute pancreatitis, 0.3% with 20% mortality; GI bleeding, 1.5% with 29% mortality; peptic ulcer disease, 0.9% with 30% mortality; and ileus, 2.2% with 26% mortality. Postoperative biliary disease (odds ratio [OR], 16.58; P = .001), hepatic dysfunction (OR, 3.58; P = .006), and bowel ischemia (OR, 10.03; P = .0001) were significantly associated with an increased postoperative mortality. Risk factors for the occurrence of GI complications were visceral involvement of the aortic repair (TAA extent II, III, and IV) (OR, 2.08; P = .002) and low preoperative glomerular filtration rate (OR, .98; P = .0002). CONCLUSION Biliary disease, hepatic dysfunction, and bowel ischemia after DTA/TAA surgical repairs were associated with an increased mortality. Visceral involvement and preoperative renal insufficiency were risk factors for the occurrence of GI complications.

Abstract
The effects of R-102444 ((2R, 4R)-4-lauroyloxy-2-[2-[2-[2-(3-methoxy)phenyl]ethyl]phenoxy]ethyl-1-methylpyrrolidine hydrochloride) and its active metabolite R-96544 ((2R, 4R)-2-[2-[2-[2-(3-methoxy)phenyl]ethyl]phenoxy]ethyl-4-hydroxy-1-methylpyrrolidine hydrochloride), potent and selective 5-hydroxytryptamine 2A (5-HT2A) receptor antagonists, on development of pancreatitis were investigated in experimental models of acute and chronic pancreatitis. Rat acute pancreatitis was induced by caerulein (20 microg/kg) intraperitoneal injection and by pancreatic duct ligation. In both the models, serum amylase and lipase activities were markedly increased. R-102444 dose-dependently reduced these enzyme activities at a dose range of 10 to 100 mg/kg (p.o.) for the caerulein model and 0.3 to 10 mg/kg (p.o.) for the ligation model. In a mouse model of acute pancreatitis induced by a choline-deficient, ethionine (0.5%)-supplemented diet, subcutaneous administration of R-96544 (10-100 mg/kg, bid) reduced serum amylase activity. Histological analysis showed that R-96544 dose-dependently attenuated pancreatic necrosis, inflammation and vacuolization. The effect of R-102444 was further examined in male Wistar Bonn/Kobori rats (4-9 months of age) which spontaneously show pancreatic fibrosis and parenchymal destruction compatible with human chronic pancreatitis. In Wistar Bonn/Kobori rats (from 3 to 9 months of age) fed a diet containing 0.017% and 0.17% of R-102444, pancreatic weight, pancreatic protein and amylase content were higher compared to those in non-treated pancreatitis control rats. Histological analysis showed that R-102444 suppressed parenchymal destruction and replacement with adipose tissue, indicating inhibition of pancreatic atrophy. These results clearly indicate that R-102444 and R-96544 inhibit the progression of acute and chronic pancreatitis and support the contention of possible involvement of 5-HT2A receptors in the progression of experimental pancreatitis.

Abstract
AIM: To observe the expressions of early growth response factor-1 (Egr-1) and tissue factor (TF) in rats with cerulein-induced acute pancreatitis and to explore its significance.
METHODS: A large dose of cerulein was used to create the experimental acute pancreatitis model in rats. The changes of Egr-1 mRNA and protein in rats were observed during 30 min to 4 h after the treatment and immunohistochemical method was used to observe the localized expression of Egr-1 in tissues. In addition to the mRNA expression of Egr-1 target gene, TF was also observed. A blank control group, and a bombesin-administered group were used for comparison.
RESULTS: After the stimulation of a large dose of cerulein, the rats showed typical inflammatory changes of acute pancreatitis. Thirty minutes after the stimulation, the mRNA expression of Egr-1 in the pancreatic tissue reached its peak and then declined, while the expression of Egr-1 protein reached its peak 2 h after the stimulation. Histologically, 2 h after the stimulation, almost all pancreatic acinar cells had the expression of Egr-1 protein, which was focused in the nuclei. The mRNA expression of TF occurred 1 h after the stimulation and gradually increased within 4 h. However, a large dose of bombesin only stimulated the pancreatic tissue to produce a little mRNA expression of Egr-1 and no mRNA expression of Egr-1 protein and TF.
CONCLUSION: Egr-1 as a pro-inflammatory transcription factor may play an important role in the pathogenesis of acute pancreatitis by modulating the expression of TF.

Abstract
STUDY OBJECTIVES To examine the incidence, risk factors, and sequelae associated with asymptomatic hyperlipasemia in the ICU. SETTING Medical and surgical ICUs. PATIENTS Two hundred forty-five adult critically ill patients admitted to an ICU for > 72 h with a diagnosis other than pancreatitis were studied prospectively. MEASUREMENTS Serum amylase and lipase were measured on ICU admission and every third day until normalized. Clinical parameters including the incidence of ileus, the ability to tolerate enteral feeds, and the results of radiologic studies were also recorded. RESULTS Hyperlipasemia was present in 40% of patients (peak, 1,183 +/- 175 U/L; range, 209 to 8,620 U/L) [mean +/- SEM]. Increased multiple-organ dysfunction scores, hypotension, anemia, mechanical ventilation (MV), bacteremia, elevated liver function test results, and elevated creatinine and triglyceride levels were all associated with increased lipase levels. In multivariate analysis, hypotension, anemia, elevated serum bilirubin, and MV were independently associated with higher lipase levels. Although mortality was not different, ICU length of stay and the duration of MV were significantly greater in patients with increased lipase levels (p < 0.05). Fifty patients underwent imaging studies. Pancreatitis was confirmed in 11 patients. The mean peak lipase value was significantly increased in patients with a positive study finding as compared to those with negative findings: 2,231 +/- 715 U/L and 900 +/- 234 U/L, respectively (p < 0.01). Enteral feedings, when initiated, were tolerated in 94% of patients with increased lipase levels and 97% of patients with normal lipase levels. CONCLUSIONS Elevated serum lipase levels are frequently encountered in critically ill patients. In the majority of these patients, enteral feedings are well tolerated and there are minimal clinical sequelae. Extremely high lipase levels may be associated with radiologic evidence of pancreatitis. Hypoperfusion and inflammatory processes associated with multiple-organ failure appear to be contribute to these increases.

Abstract
Edema formation is the first manifestation of acute pancreatitis. Microcirculatory derangements like leukocyte-endothelial cell interaction and perfusion failure result in enhancement of microvascular permeability to large molecules playing a pivotal role in the progression of the acutely altered pancreatic tissue. Due to the lack of suitable methods the crucial mechanisms of enhanced permeability in vivo are not very well investigated. Sprague-Dawley rats were randomly assigned to three groups: (a) sham operated animals with normal pancreas, (b) the pancreatitis group induced by 60 min temporary occlusion of the arterial supply followed by reperfusion and (c) the histamine group in which the pancreas was superfused with 10(-5)M histamine. The pharmacokinetics of tetramethylrhodamine-labelled BSA in the intravital microscopic images of a capillary network of the pancreas were densitometrically quantified over 20 min. From these data the effective microvascular permeability was calculated taking also into account morphology of microvessels, elimination rate of the tracer from the intravascular space and capillary microhematocrit. In addition macromolecular leakage of gold-labelled BSA was investigated by electron microscopy. Microvascular permeability was 0.10 +/- 0.02 x 10(-7) cm/s, 0.49 +/- 0.04 x 10(-7) cm/s and 1.21 +/- 0.29 x 10(-7) cm/s for control, ischemia and histamine group, respectively (P < 0.05 ischemia, histamine vs. control and ischemia vs. histamine). Electron microscopy revealed albumin extravasation in the last two groups. We established a technique allowing to quantify microvascular permeability in pancreatic tissue by dynamic intravital microscopy being independent of the investigator. This technique enabling accurate pathophysiologic characterisation in terms of edema formation can form the basis for evaluating in the future novel treatment strategies directed against acute pancreatitis.

Abstract
OBJECTIVES Ischemia-reperfusion injury can be involved in the pathophysiology of acute necrotizing pancreatitis. The aim of our study was to determine the production of cytokines, tumor necrosis factor (TNF) and interleukin-6 (IL-6), the activation of the inducible nitric oxide synthase (iNOS), and the development of apoptosis during this pathologic process. METHODS Acute pancreatitis was produced in male Wistar rats by injection of 200 microL of 6% taurocholic acid into the main pancreatic duct in combination with the temporary (15 minutes) occlusion of the inferior splenic artery. Six and 24 hours later, the histologic damage was evaluated, and serum amylase, TNF, IL-6 levels, and iNOS and apoptotic activity from pancreatic and pulmonary tissues were determined. RESULTS Twenty-four hours after the induction of pancreatitis, the mortality rate was 63%. During this period, the serum TNF and IL-6 levels were permanently high (50 +/- 12 and 58 +/- 10 U/mL and 7083 +/- 1610 and 6790 +/- 850 U/mL after 6 and 24 hours, respectively). The iNOS activity showed an increasing tendency in the pancreas, and a decrease following an initial increase in the lung (from 4.2 +/- 0.6 to 5 +/- 0.4 and from 6.8 +/- 0.6 to 3.8 +/- 0.5 pmol/min/mg protein after 6 and 24 hours, respectively). Histologic examination confirmed severe necrotizing pancreatitis. In the pancreas, the apoptotic activity increased significantly (from 4 +/- 4 to 27 +/- 5/mm at 6 and 24 hours), while in the lungs, following an initial increase it declined during the course of necrotizing pancreatitis (from 49 +/- 4 to 11 +/- 6/mm at 6 and 24 hours). CONCLUSION Our results indicate that intraductal taurocholic acid and ischemia-reperfusion provokes severe acute necrotizing pancreatitis with a high mortality rate and leads to systemic inflammatory reaction, which appears to be the consequence of the activation of the cytokine cascade and iNOS. The degree of NO overproduction by iNOS corresponds with the apoptotic process in the pancreas and the lung.

Abstract
In various organs, including heart, kidneys, brain, liver and stomach, preconditioning by brief exposure to ischemia protects the organ against damage evoked by subsequent severe ischemia. This study has been undertaken to check whether two brief ischemic periods protect the pancreas against severe ischemia/reperfusion-induced pancreatitis and, if so, what is the role of sensory and vagal nerves in this phenomenon. In male Wistar rats, the ischemic preconditioning of the pancreas was performed by clamping of celiac artery (2 x 5 min with 5 min interval). Thirty minutes after preconditioning or sham operation, the ischemia/reperfusion-induced pancreatitis was evoked by clamping of inferior splenic artery for 30 min using microvascular clips, followed by 1 h reperfusion. Sensory nerves ablation was induced 10 days before final experiments by capsaicin. Truncal vagotomy was performed 1 week before the experiment. Exposure to regular 30-min pancreatic ischemia followed by 1 h reperfusion led to the development of acute hemorrhagic pancreatitis. Ischemic preconditioning, applied prior to induction of pancreatitis, caused the reduction in plasma lipase, plasma interleukin-1beta and histological signs of pancreatic damage, as well as attenuated the reduction in pancreatic blood flow and DNA synthesis. Ablation of sensory nerves by capsaicin caused an aggravation of ischemia/reperfusion-induced pancreatic damage and attenuated a protective effect of ischemic preconditioning. Noxious effect of sensory nerves ablation on the pancreas was accompanied by the reduction in pancreatic blood flow and an increase in plasma interleukin-1beta. Similar but less pronounced deleterious effect on the pancreas was observed after vagotomy. We conclude that: (1) pancreatic ischemic preconditioning reduces the severity of ischemia/reperfusion-induced pancreatitis; (2) this effect seems to be related, at least in part, to the improvement of pancreatic blood flow and the reduction in the release of proinflammatory interleukin-1beta; (3) sensory and vagal nerves are involved in protective effect of ischemic preconditioning against pancreatic damage.

Abstract
BACKGROUND Reperfusion injury contributes to early organ malfunction after transplantation. The aim of this study was to characterize the ischemia-reperfusion injury after pancreas transplantation and to evaluate the effect of monoclonal antibody therapy against ICAM-1. METHODS Twenty-five heterotopic pancreas transplantations were performed in syngenic rats in a no-touch technique. Microcirculation and leukocyte-endothelial interaction in the grafts were evaluated by intravital microscopy at 1 hour (I), 6 hours (II), 12 hours (III), and 24 hours (IV) after reperfusion, and 12 hours after reperfusion (V) in the therapeutic group. In (V) antibodies against ICAM-1 were applied as bolus at reperfusion and continuously for 6 hours. Next to intravital microscopy, histologic scores, myeloperoxidase levels, and ICAM-1 expression were determined. RESULTS Microcirculation was significantly reduced in capillaries and postcapillary venules in the time course after reperfusion (capillary: 0.96 +/- 0.08 mm/s [I] to 0.45 +/- 0.07 mm/s [IV] [P <.01]) and was improved significantly by therapy with ICAM-1 antibodies (0.98 +/- 0.06 mm/s, (P <.01). Leukocyte-endothelial interaction significantly increased 6 hours after reperfusion (II) (P <.01). These changes were paralleled by an increased endothelial expression of ICAM-1 in immunohistochemistry. Histologic evaluation showed increased inflammation at 12 hours after reperfusion (P <.01), which could be diminished by the administration of ICAM-1 antibodies (P <.05). CONCLUSION Increased endothelial expression of ICAM-1 after pancreas transplantation is positively correlated with microcirculatory impairment. Important steps of pancreatic inflammation take place approximately 6 hours after reperfusion. Prophylactic application of monoclonal antibodies against ICAM-1 reduces reperfusion injury and successfully prevents the occurrence of graft pancreatitis.

Abstract
Thrombotic thrombocytopenic purpura (TTP) is a rare clinical entity. It is a multi-systemic disorder characterized by a clinical pentad of thrombocytopenia, microangiopathic hemolytic anemia, diffuse and nonfocal neurologic symptoms, decreased renal function, and fever. Abdominal pain is an uncommon presenting symptom for TTP. Pancreatitis may occur from TTP or, in a few cases, may trigger TTP. The clinical diagnosis of TTP is generally difficult because there are many varied clinical presentations and the full expression of the pentad may be prolonged. However, once the diagnosis is suspected or confirmed, immediate plasmapherseis with plasma exchange must be performed to reduce the severe morbidity from neurologic disability.

Abstract
INTRODUCTION Capillary perfusion failure of the pancreatic microcirculation is characteristic in the pathogenesis of acute pancreatitis and ischemia-reperfusion damage after pancreas transplantation. Up to now, no logistic suitable method for analyzing pancreatic capillary perfusion during operations in humans has been established without the use of fluorescent dyes. AIM To compare the well-established technique of intravital epifluorescence microscopy with the novel noninvasive method of orthogonal polarization spectral (OPS) imaging for measurement of the pancreatic functional capillary density. METHODOLOGY In eight anesthetized rats, six identical capillary regions of interest per animal were measured by both methods, and the results were compared. RESULTS Absolute values from the capillary perfusion data were not significantly different between the two methods (fluorescence microscopy: 394 +/- 44 cm/cm2; OPS imaging: 385 +/- 45 cm/cm2). Correlation parameters were significant, and Bland-Altman analyses showed good agreement with a mean difference (bias) between the two methods of 6.9 cm/cm2, indicating that slightly smaller values are measured with OPS imaging. CONCLUSION OPS imaging is a valid noninvasive method that analyzes the pancreatic microcirculation as accurately as the established intravital microscopy technique and therefore could be useful for clinical research and diagnosis during transplantation and operations.

Abstract
INTRODUCTION Microcirculatory disturbances caused by ischemia-reperfusion injury (IRI) are the crucial hallmarks of pancreatitis following pancreas transplantation. AIMS To develop a novel rodent model of normothermic in situ ischemia of a pancreatic tail-segment that simulates the clinical situation of pancreas transplantation by flushing the organ via an inserted microcatheter and thus enables selective treatment of the organ via this access. METHODOLOGY Four experimental groups were investigated (n = 7 Wistar rats/group): sham animals without ischemia and dissection of the pancreas; control animals with dissection of a pancreatic tail segment pedunculated on the splenic vessels and flushing od this segment with saline via a microcatheter; and two groups of animals treated like controls with a pancreatic ischemia time of 1 hour or 2 hours. With use of intravital epifluorescence microscopy, the microcirculatory damage was characterized by investigation of functional capillary density (FCD) and leukocyte adherence in postcapillary venules (LAV) before ischemia and during a reperfusion time of 2 hours. Dry:wet ratio determinations, light microscopy, and electron microscopic investigations were performed to characterize the histologic organ damage. RESULTS FCD decreased significantly (p < 0.05) 2 hours after reperfusion in the groups of 1-hour (-29.21%) and 2-hour ischemia (-42.73%), in comparison with baseline values. LAV increased significantly (p < 0.05), 4.3- and 5.8-fold, after 1-hour and 2-hour ischemia during the observation time. The histologic damage was similar to posttransplantation pancreatitis in humans 1 hour after reperfusion. In sham and control animals these alterations were not significant. CONCLUSIONS The rodent in situ model of pancreatic IRI showed standardized microcirculatory damage dependent on the ischemia time. Offering the possibility of selective treatment by the direct artery access to the ischemic pancreatic area, the model enables investigations of questions related to human pancreas transplantation.

Abstract
INTRODUCTION Acute pancreatitis after surgical treatment of non ruptured aneurysm of abdominal aorta is a rare complication, considered to be due to pancreatic ischemia or peroperative trauma of pancreas. The aim of this study is to describe 4 new cases of this complication and to discuss its etiology. PATIENTS AND METHODS From January 1995 to November 2000, 365 patients underwent elective surgery for a non ruptured abdominal aorta aneurysm. Four (1.1%) men, aged 66 to 79 years and operated for an aneurysm which diameter ranged from 60 to 77 mm, developed postoperative acute pancreatitis. The abdominal approach was a midline incision in 3 cases and a retroperitoneal lombotomy in one case. Superior pole of the aneurysm always adjoined or involved the right renal artery. The aortic clamping was supra-renal in 3 cases and celiac in one case. Diagnosis of acute pancreatitis was established at days 2, 4, 12, and 23 after surgery on abdominal computed tomography in 3 cases and at reoperation in one case. RESULTS Three patients died, including 2 from early multiple organ failure and one peroperatively during surgical attempt to treat a prostheto-digestive fistula. One patient was alive and asymptomatic with a 2-years follow-up. CONCLUSION Acute pancreatitis is a rare and serious complication after surgical treatment of abdominal aorta aneurysm. Its diagnosis is often delayed. The main etiological factor of this complication could be trauma of pancreas during supra-renal clamping through a midline incision.

Abstract
Hepatocyte growth factor (HGF) overexpression was reported in experimental and clinical acute pancreatitis. These observations prompted us to determine the effect of HGF administration on the development of caerulein-induced pancreatitis in rats. Acute pancreatitis was induced by s.c. infusion of caerulein (10 microg/kg/h) for 5 h. HGF was administrated twice (30 min before caerulein or saline infusion and 3 h later) at the doses: 0.4, 2, 10 or 50 microg/kg s.c. Immediately after cessation of caerulein or saline infusion, the pancreatic blood flow, plasma amylase and lipase activity, plasma cytokines concentration, cell proliferation, and morphological signs of pancreatitis were examined. Caerulein administration induced acute edematous pancreatitis manifested by 41% decrease in DNA synthesis, 53% inhibition of pancreatic blood flow, a significant increase in plasma amylase and lipase activity, plasma interleukin-1beta and interleukin-6 concentration, as well as, the development of the histological signs of pancreatic damage (edema, leukocyte infiltration, and vacuolization). Administration of HGF without induction of pancreatitis increased plasma interleukin-10. Treatment with HGF, during induction of pancreatitis, increased plasma interleukin-10 and attenuated the pancreatic damage, what was manifested by histological improvement of pancreatic integrity, the partial reversion of the drop in DNA synthesis and pancreatic blood flow, and the reduction in pancreatitis evoked increase in plasma amylase, lipase, and interleukin-1beta and interleukin-6 levels. HGF administrated at the dose 2 microg/kg exhibited a similar beneficial effect as administration of HGF at the doses 10 or 50 microg/kg. Treatment with HGF at the dose 0.4 microg/kg was less effective. We conclude that: (1) administration of HGF attenuates pancreatic damage in caerulein-induced pancreatitis; (2) this effect seems to be related to the increase in production of interleukin-10, the reduction in release of interleukin-1beta and interleukin-6, and the improvement of pancreatic blood flow.
