Astaxanthin Inhibits Interleukin-6 Expression in Cerulein/Resistin-Stimulated Pancreatic Acinar Cells. Mediators Inflamm 2021; 2021:5587297.

Abstract
Acute pancreatitis is a common clinical condition with increasing the proinflammatory mediators, including interleukin-6 (IL-6). Obesity is a negative prognostic factor in acute pancreatitis. Obese patients with acute pancreatitis have a higher systemic inflammatory response rate. Levels of serum resistin, an adipocytokine secreted by fat tissues, increase with obesity. Cerulein, a cholecystokinin analog, induces calcium (Ca2+) overload, oxidative stress, and IL-6 expression in pancreatic acinar cells, which are hallmarks of acute pancreatitis. A recent study showed that resistin aggravates the expression of inflammatory cytokines in cerulein-stimulated pancreatic acinar cells. We aimed to investigate whether resistin amplifies cerulein-induced IL-6 expression and whether astaxanthin (ASX), an antioxidant carotenoid with anti-inflammatory properties, inhibits ceruelin/resistin-induced IL-6 expression in pancreatic acinar AR42J cells. We found that resistin enhanced intracellular Ca2+ levels, NADPH oxidase activity, intracellular reactive oxygen species (ROS) production, NF-κB activity, and IL-6 expression in cerulein-stimulated AR42J cells, which were inhibited by ASX in a dose-dependent manner. The calcium chelator BAPTA-AM inhibited cerulein/resistin-induced NADPH oxidase activation and ROS production. Antioxidant N-acetyl cysteine (NAC) and ML171, a specific NADPH oxidase 1 inhibitor, suppressed cerulein/resistin-induced ROS production, NF-κB activation, and IL-6 expression. In conclusion, ASX inhibits IL-6 expression, by reducing Ca2+ overload, NADPH oxidase-mediated ROS production, and NF-κB activity in cerulein/resistin-stimulated pancreatic acinar cells. Consumption of ASX-rich foods could be beneficial for preventing or delaying the incidence of obesity-associated acute pancreatitis.

Abstract
Objective To investigate the correlation between the level of glucose in serum and the development of acute pancreatitis (AP). Methods Data of 153 AP cases were collected, in which there were 130 patients with mild AP (MAP), 4 with moderate-severe AP (MSAP) and 19 with severe AP (SAP). At the time of admission, following indexes of patients were recorded: glucose, APACHE II score, TNF-α and C-reaction protein (CRP). Results At the time of admission, the levels of glucose in serum and APACHE II scores in the MSAP and SAP groups were significantly higher than those in the MAP group, but after treatment, the level of glucose in serum was recovered in 95.8% of the patients in the MAP group, while this digit in the SAP group remained to be 68.4%; in the SAP group, the levels of TNF-α and CRP in patients with sustained hypertension were significantly higher than those with non-persistent hypertension; in terms of the length of stay in hospital, the SAP group was shorter than that in the non-treatment group, and the difference had statistical significance (p < 0.05). Moreover, we found that the level of glucose in serum was positively correlated with the APACHE II scores, TNF-α and CRP. Conclusion Glucose level in serum can be used as one of the indicators for evaluating the severity and development of AP in clinical practice.

Abstract
Growing scientific evidence has unveiled increased incidences of obesity in domestic animals and its influence on a plethora of associated disorders. Leptin, an adipokine regulating body fat mass, represents a key molecule in obesity, able to modulate immune responses and foster chronic inflammatory response in peripheral tissues. High levels of cytokines and inflammatory markers suggest an association between inflammatory state and obesity in dogs, highlighting the parallelism with humans. Canine obesity is a relevant disease always accompanied with several health conditions such as inflammation, immune-dysregulation, insulin resistance, pancreatitis, orthopaedic disorders, cardiovascular disease, and neoplasia. However, leptin involvement in many disease processes in veterinary medicine is poorly understood. Moreover, hyperleptinemia as well as leptin resistance occur with cardiac dysfunction as a consequence of altered cardiac mitochondrial metabolism in obese dogs. Similarly, leptin dysregulation seems to be involved in the pancreatitis pathophysiology. This review aims to examine literature concerning leptin and immunological status in obese dogs, in particular for the aspects related to obesity-associated diseases.

Abstract
Objecives To compare the clinical outcome of patients with extrapancreatic necrosis (EXPN) alone with that of acute interstitial pancreatitis (AIP), pancreatic parenchymal necrosis (PPN) alone, and combined PPN and EXPN. Background There are only a few studies in the literature in which EXPN has been recently recognized as a subtype of acute necrotizing pancreatitis (ANP), with a better prognosis. Methods We analyzed clinical data and outcome variables of 411 consecutive acute pancreatitis (AP) patients between January 2012 and December 2014. Contrast‐enhanced computed tomography (CECT) images of each patient were reviewed and characterized as AIP or ANP. Patients with ANP were divided into EXPN alone, PPN alone, and combined PPN and EXPN. Outcome variables were then compared between these groups. Results Of the 411 patients, 74 (18%) had AIP, and 337 (82%) had ANP. Patients with EXPN alone (n = 40; 11.8%) had similar outcomes as patients with PPN alone (n = 12; 3.5%); however, their outcome was worse than that of patients with AIP, with a higher frequency of persistent organ failure (POF), need for percutaneous catheter drainage (PCD), and longer length of hospitalization (LOH). Patients with combined PPN and EXPN (n = 285; 84.7%) had the worst clinical course, with higher frequency of POF, infected necrosis, intervention requirement, and longer LOH. Conclusion Patients with combined PPN and EXPN have a severe disease course with the worst clinical outcomes; patients with AIP patients have the most benign course, while patients with EXPN alone stand between the two extremes of disease course with an intermediate grade of severity.

Abstract
BACKGROUND Adipose tissue is an endocrine organ that plays a critical role in immunity and metabolism by virtue of a large number of hormones and cytokines, collectively termed adipokines. Dysregulation of adipokines has been linked to the pathogenesis of multiple diseases, but some questions have arisen concerning the value of adipokines in critical illness setting. The objective of this review was to evaluate the associations between blood adipokines and critical illness outcomes. METHODS PubMed, CINAHL, Scopus, and the Cochrane Library databases were searched from inception through July 2016 without language restriction. Studies reporting the associations of adipokines, leptin, adiponectin, resistin, and/or visfatin with critical illness outcomes mortality, organ dysfunction, and/or inflammation were included. RESULTS A total of 38 articles were selected according to the inclusion/exclusion criteria of the study. Significant alterations of circulating adipokines have been reported in critically ill patients, some of which were indicative of patient outcomes. The associations of leptin and adiponectin with critical illness outcomes were not conclusive in that blood levels of both adipokines did not always correlate with the illness severity scores or risks of organ failure and mortality. By contrast, studies consistently reported striking increase of blood resistin and visfatin, independently of the critical illness etiology. More interestingly, increased levels of these adipokines were systematically associated with severe inflammation, and high incidence of organ failure and mortality. CONCLUSIONS There is strong evidence to indicate that increased levels of blood resistin and visfatin are associated with poor outcomes of critically ill patients, including higher inflammation, and greater risk of organ dysfunction and mortality. LEVEL OF EVIDENCE Systematic review, level III.

Abstract
BACKGROUND To investigate the accuracy of resistin, leptin and adiponectin levels in predicting persistent organ failure in patients with acute pancreatitis (AP). METHODS Data from 90 consecutive patients admitted to our hospital for AP were retrospectively collected from an ongoing prospective cohort study. The levels of adiponectin, leptin and resistin were measured and compared between patients with and without persistent organ failure. The accuracy of the adipokines in predicting persistent organ failure were compared with the patients' Acute Physiology and Chronic Health Evaluation II (APACHE-II) score, and were separately investigated in overweight and non-overweight groups. RESULTS Persistent organ failure occurred in 26.7% of the patients. The levels of resistin were significantly increased in AP patients with persistent organ failure, in both the overweight and the non-overweight subgroups. Resistin and APACHE-II score predicted persistent organ failure with comparable areas under the curve (AUC) of 0.72 and 0.75, respectively (p = 0.66). Resistin demonstrated similar accuracy with the APACHE-II score in predicting persistent organ failure in the overweight (0.69 vs. 0.66, p = 0.82) and non-overweight (0.76 vs. 0.87, p = 0.39) subgroups. There was no correlation between adiponectin and persistent organ failure, but a weak correlation between leptin and persistent organ failure was demonstrated. CONCLUSIONS Resistin and leptin levels, rather than adiponectin, correlate with persistent organ failure in patients with AP.

Abstract
Background Recent data shows that patients with severe acute pancreatic might benefit from early intensive therapy, enteral nutrition and timely transfer to specialized centers. The early prophylactic use of antibiotics in AP remains controversial. The role and need for new markers in stratification of acute pancreatitis is also uncertain. This study aims to evaluate the prognostic usefulness of adipokines in prediction of the severity and outcome of acute pancreatitis (AP). Methods Prospective study was conducted in four clinical centers. The diagnosis and severity assessment of AP was established according to the revised 2012 Atlanta classification. Adipokines, IL-6 and CRP levels were measured at admission and on 3rd day of hospital stay and compared with the control group. The predictive accuracy of each marker was measured by area under the receiver operating curve. Results Forty healthy controls and 102 patients were enrolled in to the study. Twenty seven (26.5 %) patients had mild, 55 (53.9 %) - moderate and 20 (19.6 %) - severe AP. Only resistin (cut-off value 13.7 ng/ml) and IL-6 (cut-off value 473.4 pg/ml) were reliable early markers of SAP. IL-6 with cut-off value of 157.0 pg/ml was a predictor of necrosis. The peripancreatic necrosis volume of 112.5 ml was a marker of SAP and 433.0 ml cut-off value could be used to predict the need of interventions. Conclusions The prognostic value of adipokines in AP is limited. Only admission resistin levels could serve as an early predictor for SAP. The Lithuanian Regional Ethics Committee approved the study protocol (permission No. L-12-02/1/2/3/4) and all the patients and the control group provided written informed consent.

Abstract
Acute pancreatitis is of two morphologic types: interstitial edematous pancreatitis that is not associated with any tissue necrosis and necrotizing pancreatitis wherein the pancreatic parenchyma with or without varying amount of extra-pancreatic tissue/fat undergoes necrosis. Necrotizing pancreatitis has a worse outcome compared with interstitial pancreatitis because of increased severity related to a heightened systemic response and cytokine storm associated with tissue necrosis. Increasingly, an entity of extra-pancreatic necrosis (EPN) alone, wherein the pancreatic parenchyma is normal on an enhanced computed tomographic scan but the peri-pancreatic tissues undergo necrosis, is being recognized. Available data suggest that the outcomes in patients with EPN alone are between the excellent prognosis of patients with interstitial and adverse prognosis of patients with necrotizing pancreatitis. The extent of EPN also seems to determine the outcome. This review summarizes the currently available literature on this entity and various radiological scores that have been suggested to determine the presence and stage of EPN.

Abstract
BACKGROUND Resistin level is high in patients with severe acute pancreatitis (SAP), and resistin is expected to be a new marker for evaluating the severity of acute pancreatitis. OBJECTIVE To explore the influence of integrated traditional Chinese and Western medicine therapy on serum resistin levels in SAP patients. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS Twenty-eight SAP patients meeting inclusion criteria from Department of Integrated Traditional Chinese and Western Medicine, West China Hospital, Sichuan University were included, and the patients were randomly divided into treatment group and placebo group. There were 13 patients in the treatment group and 15 patients in the placebo group. Patients in the treatment group were given traditional Chinese herbal medicine in addition to the conventional treatment. Patients in the placebo group were given placebo in addition to the conventional treatment. MAIN OUTCOME MEASURES The serum resistin levels on admission, and days 1, 3, 5, and 7 after the admission were detected. RESULTS The serum resistin levels on admission in all the patients were higher than normal level, and there was no significant difference between the two groups (P>0.05). On days 1, 3, 5, and 7 after admission, the resistin levels in the treatment group were (3.29 + or - 1.66) microg/L, (3.71 + or - 1.05) microg/L, (3.08 + or - 1.47) microg/L and (3.62 + or - 1.67) microg/L, and in the control group (5.16 + or - 1.93) microg/L, (5.07 + or - 1.53) microg/L, (4.88 + or - 1.47) microg/L and (5.12 + or - 1.48) microg/L, respectively. The resistin levels were lower in the treatment group than in the control group (P<0.05). CONCLUSION Serum resistin level in SAP patients can be decreased by integrated traditional Chinese medicine and Western medicine therapy.

Abstract
Acute pancreatitis (AP) is an inflammatory disorder of the exocrine pancreas frequently associated with metabolic causes, contributing factors, or consequences, including hypertriglyceridemia, obesity, and disorders of intermediary metabolism, respectively. To date, there is no specific therapy for this disease. Future optimal therapy should correct both inflammatory and metabolic components of the disease. Peroxisome proliferator-activated receptors (PPARs) are lipid-sensing nuclear receptors that control inflammatory and metabolic pathways via ligand-dependent and ligand-independent mechanisms. There are 3 known subtypes, PPAR-α, PPAR-β/δ, and PPAR-γ, which are differentially expressed in various tissues. The PPARs interact closely with other transcription factors such as nuclear factor κB and signal tranducers and activators of transcription that have pivotal roles in the pathobiology of AP. In this comprehensive review, we summarize the role of PPARs in AP, highlighting important in vitro and in vivo experimental findings. Finally, we propose future research directions as well as potential translational use of PPAR agonists in the treatment of AP.

Abstract
The mechanism behind the beneficial effects of enteral nutrition (EN) for patients with acute pancreatitis (AP) is largely unknown. Adipokines, as mediators of metabolism and inflammation, may be a possible mechanism. The study aimed to investigate the effect of EN on adipokines early in the course of AP. Patients with AP were randomised to EN or nil-by-mouth (NBM). Blood samples were taken on the first 4 d of admission and adipokine concentrations for adiponectin, leptin, omentin, resistin and visfatin were determined by ELISA assays. A linear mixed model analysis was run to determine differences in adipokine concentrations between the two study groups. A total of thirty-two patients were included in the study. Omentin concentrations were significantly higher in patients who received EN compared with NBM across the first 4 d of admission (mean difference: 11·6 (95 % CI 1·0, 22·3) ng/ml; P = 0·033). Leptin concentrations were significantly higher in patients who received EN compared with NBM after adjusting for age, sex and BMI (mean difference: 2·3 (95 % CI 0·1, 4·5) ng/ml; P = 0·037). No significant difference in adiponectin, resistin or visfatin concentrations were observed between the two study groups. EN significantly increases omentin and leptin concentrations in AP. Future research should be directed towards understanding whether these adipokines are responsible for the therapeutic benefits of EN.

Abstract
The aim of the present study was to detect the expression of resistin in rats with acute pancreatitis (AP) and investigate its significance in the pathogenesis of AP. In total, 40 Sprague-Dawley rats were randomly divided into four groups (n=10), including the normal control, sham-operated, acute edematous pancreatitis (AEP) and acute necrotizing pancreatitis (ANP) groups. Following the establishment of animal models, the levels of serum resistin, C-reactive protein (CRP), tumor necrosis factor-α (TNF-α) and interleukin (IL)-1β were measured using ELISA. Resistin expression in the pancreatic tissues was detected using an immunohistochemical method. In addition, the mRNA expression of resistin in the pancreatic tissues was analyzed with quantitative polymerase chain reaction. The levels of serum amylase, serum resistin, TNF-α, IL-1β and CRP were all significantly higher in the AEP and ANP groups when compared with the control and sham-operated groups (P<0.01), as were the pancreas/body weight ratios and pathological scores of the pancreas. These increases were more significant in the ANP group than in the AEP group (P<0.05). The mRNA expression levels of resistin in the pancreatic tissues were markedly higher in the AEP and ANP groups when compared with the control and sham-operated groups (P<0.01), particularly in the pancreatic tissues of the ANP group, which exhibited notably higher levels compared with the AEP group. The serum resistin level was found to positively correlate with the serum levels of CRP, TNF-α and IL-1β, and the pathological scores of the pancreatic tissues. In conclusion, the results indicated that resistin may be associated with the occurrence and development of AP; thus, the protein may be a valuable indicator for assessing the severity of AP.

The potential role of BMI, plasma leptin, nesfatin-1 and ghrelin levels in the early detection of pancreatic necrosis and severe acute pancreatitis: a prospective cohort study. Int J Surg 2014; 12:1310-3. [PMID: 25448651 DOI: 10.1016/j.ijsu.2014.10.040] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2014] [Revised: 07/29/2014] [Accepted: 10/29/2014] [Indexed: 10/24/2022]
Abstract
BACKGROUND Early prediction of disease severity in acute pancreatitis (AP) is crucial. The aim of this study was to investigate the body-mass index (BMI), plasma leptin, nesfatin-1 and ghrelin levels as potential markers predicting peripancreatic necrosis and severity in acute pancreatitis. METHODS In the study period, 97 consecutive patients with AP were prospectively analysed. Severe AP was defined according to the Atlanta Criteria. BMI was also calculated. To measure plasma Leptin, Nesfatin-1 and Ghrelin concentrations, the blood samples were obtained from patients within 24 hours of admission. RESULTS Out of 97 patients, 92(70 females, 22 males) were considered eligible for analysis. Of the 92 patients, 30 patients (32.6%) were assessed as severe pancreatitis. BMI and leptin levels were significantly higher in patients with severe pancreatitis. The pooled sensitivity and specificity of BMI as a predictor for the development of pancreatic necrosis were 0.90(95%CI = 0.56-0.99) and 0.70(95%CI = 0.58-0.79), respectively; with an overall area under curve value of 0.78.The pooled sensitivity and specificity of leptin levels as a predictor for development of pancreatic necrosis were 1(95%CI = 0.69-1) and 0.73(95%CI = 0.62-0.82),respectively; with an overall area under curve value of 0.82.Nesfatin-1 and ghrelin levels showed no significant difference in patients with mild pancreatitis (6.97 ± 0.84 ng/ml and 2.3(1.0-9.9);respectively) and severe pancreatitis (6.74 ± 0.65 ng/ml and 2.0(1.9-9.9); respectively) (p = 0.1923 and 0.8531;respectively). CONCLUSION BMI and plasma leptin levels both were correlated with the severity of pancreatitis. Leptin levels showed better area under the curve, sensitivity and specificity values compared to BMI in prediction of pancreatic necrosis.Nesfatin-1 and ghrelin levels were not found to be predictors of the severity of disease.

Abstract
Background Limited information is available about the role of adipokines in the development and progression of acute pancreatitis (AP) in dogs. Objectives To determine whether the circulating concentrations of adipokines differed between healthy dogs and dogs with AP, and whether the circulating concentrations differed between AP survivors and AP nonsurvivors. Animals Twenty‐eight healthy dogs and 25 client‐owned dogs with AP. Methods Prospective observational cohort study of 25 client‐owned dogs with newly diagnosed AP and 28 otherwise healthy dogs with similar body condition scores. The serum concentrations of leptin, adiponectin, resistin, visfatin, interleukin (IL)‐1β, IL‐6, IL‐10, IL‐18, and tumor necrosis factor (TNF)‐α were measured. Results The serum concentrations of leptin (P = .0021), resistin (P = .0010), visfatin (P < .0001), IL‐1β (P < .0001), IL‐6 (P = .0002), IL‐10 (P < .0001), and IL‐18 (P < .0001) were significantly higher in dogs with AP than healthy dogs, whereas the adiponectin concentration (P = .0011) was significantly lower. There were significant differences in the serum concentrations of leptin (P = .028) and adiponectin (P = .046) in survivors and nonsurvivors. After the disappearance of clinical signs, the concentrations of resistin (P = .037) and IL‐1β (P = .027) decreased significantly, whereas the serum concentrations of leptin (P > .999), adiponectin (P = .11), visfatin (P = .83), IL‐6 (P = .82), IL‐10 (P = .82), IL‐18 (P = .56), and TNF‐α (P = .94) did not differ significantly. Conclusion and Clinical Importance This study showed that dysregulation of adipokines might be involved in the pathogenesis of AP. In addition, leptin and adiponectin are likely to be associated with mortality rate in AP.

Abstract
AbstractTo evaluate the effectiveness of serum levels of resistin and CD14 expression in monocytes, and high-sensitivity C-reactive protein (hsCRP) in early stages of acute pancreatitis and correct prediction of the severity of acute pancreatitis (AP) using scoring systems. The study involved 10 (29.41%) male and 24 (70.59%) female patients (total n=34) followed for AP diagnosis at the Department of General Surgery, Ataturk University Medical School between July 2008 and September 2009. In all the patients, Ranson and APACHE II scores, serum resistin, hsCRP, and monocyte CD14 expression levels were determined. The patients were divided into two groups as mild and severe AP groups. A control group was formed and the intergroup comparisons were made. Values ≥ 3 based on the Ranson scoring scale and values ≥ 8 in APACHE II scoring scale were considered to indicate severe AP. Evaluations were based on the values obtained on the 1st and 7th days for serum resistin and hsCRP levels and monocyte CD 14 expression. In 17 (50%) patients, severe AP was determined. No statistically significant differences were found between the mean serum resistin levels of AP groups, while the difference for the same parameter between the mild and severe AP groups and the control group was statistically significant. In the severe AP group, the mean 1st day and 7th day serum hsCRP levels were statistically significantly higher. The CD14 expression in monocytes was similar in all the groups. Serum hsCRP concentrations and Ranson and APACHE II scores and serum resistin and hsCRP concentrations on the 1st day were positively correlated. Serum hsCRP measurement is effective in determining the severity of acute pancreatitis. Serum resistin measurement may be a useful early marker in determining the inflammatory response in AP. However, CD14 expression in monocytes was not found to be a useful marker in the diagnosis and prediction of the disease severity in AP patients.

[PMID: 23236237 PMCID: PMC3516219 DOI: 10.3748/wjg.v18.i45.6620] [Citation(s) in RCA: 30] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/10/2012] [Revised: 09/18/2012] [Accepted: 09/22/2012] [Indexed: 02/06/2023] Open
Abstract
AIM: To analyze the prognostic value of adipokines in predicting the course, complications and fatal outcome of acute pancreatitis (AP).
METHODS: We performed the search of PubMed database and the systemic analysis of the literature for both experimental and human studies on prognostic value of adipokines in AP for period 2002-2012. Only the papers that described the use of adipokines for prediction of severity and/or complications of AP were selected for further analysis. Each article had to contain information about the levels of measured adipokines, diagnosis and verification of AP, to specify presence of pancreatic necrosis, organ dysfunction and/or mortality rates. From the very beginning, study was carried out adhering to the PRISMA checklist and flowchart for systemic reviews. To assess quality of all included human studies, the Quality Assessment of Diagnostic Accuracy Studies tool was used. Because of the high heterogeneity between the studies, it was decided to refrain from the statistical processing or meta-analysis of the available data.
RESULTS: Nine human and three experimental studies were included into review. In experimental studies significant differences between leptin concentrations at 24 and 48 h in control, acute edematous and acute necrotizing pancreatitis groups were found (P = 0.027 and P < 0.001). In human studies significant differences between leptin and resitin concentrations in control and acute pancreatitis groups were found. 1-3 d serum adiponectin threshold of 4.5 μg/mL correctly classified the severity of 81% of patients with AP. This threshold yielded a sensitivity of 70%, specificity 85%, positive predictive value 64%, negative predictive value88% (area under curve 0.75). Resistin and visfatin concentrations differ significantly between mild and severe acute pancreatitis groups, they correlate with severity of disease, need for interventions and outcome. Both adipokines are good markers for parapancreatic necrosis and the cut-off values of 11.9 ng/mL and 1.8 ng/mL respectively predict the high ranges of radiological scores. However, the review revealed that all nine human studies with adipokines are very different in terms of methodology and objectives, so it is difficult to generalize their results. It seems that concentrations of the leptin and resistin increases significantly in patients with acute pancreatitis compared with controls. Serum levels of adiponectin, visfatin and especially resitin (positive correlation with Acute Physiology and Chronic Health Evaluation II, Ranson and C-reactive protein) are significantly different in mild acute pancreatitis and severe acute pancreatitis patients, so, they can serve as a markers for the disease severity prediction. Resistin and visfatin can also be used for pancreatic and parapancreatic necrosis prediction, interventions needs and possible, outcome.
CONCLUSION: High levels of adipokines could allow for prediction of a severe disease course and outcome even in small pancreatic lesions on computed tomography scans.

Abstract
OBJECTIVES Obesity markedly increases the risk of severe acute pancreatitis (AP). Several adipokines have been ascribed a role as a predictor of clinical severity in AP. Therefore, the aim of this study was to investigate a possible relationship between leptin and adiponectin and mild biliary AP. METHODS We included 24 consecutive patients with mild biliary AP and 24 consecutive healthy age- and sex-matched controls. Clinical severity was classified by the Ranson score. ELISA was used to assess leptin and adiponectin levels on admission and in remission. Complete blood cell counts and other laboratory tests were also performed at baseline and in remission. RESULTS Leptin, adiponectin, insulin and HOMA-IR measurements showed no difference in pancreatitis patients both on admission and in remission compared to the control group. No difference was found in leptin, insulin or HOMA-IR levels in the course of pancreatitis. However, adiponectin levels were higher in remission compared to admission. CONCLUSIONS Increased adiponectin levels in remission may be an indication of improvement in this condition. Further studies are needed to determine whether adiponectin provides protection from AP.

Abstract
BACKGROUND Obesity plays an important role in acute pancreatitis. Assuming that the volume of visceral adipose tissue (VAT) directly influences the severity of acute pancreatitis, we investigated the relationship between VAT and acute pancreatitis. METHODS Data were collected consecutively from 124 patients who were diagnosed with acute pancreatitis. Body mass index (BMI) was calculated from the database. Computed tomography was performed in all patients, and VAT, subcutaneous adipose tissue (SAT), and waist circumference (WC) were measured at the level of the intervertebral disk between L2 and L3. Atlanta criteria were adopted to define severe acute pancreatitis. Clinical courses were investigated, and the Ranson and acute physiology and chronic health evaluation II (APACHE II) scores were calculated for all patients. RESULTS Forty-eight patients had severe acute pancreatitis (38.7%), and 76 were mild cases. BMI, VAT, SAT, and WC were correlated with the severity of acute pancreatitis in a univariate analysis, but only VAT had a strong correlation with severe acute pancreatitis in the multivariate analysis. In a trend analysis, not only severity but also the presence of pseudocysts (local complication) and prognostic factors (Ranson and APACHE II scores) were significantly related to VAT volume. In particular, the presence of a pancreatic pseudocyst was strongly related to VAT volume (p < 0.001). CONCLUSION In acute pancreatitis, peripancreatic VAT has a stronger correlation with severe acute pancreatitis than BMI or WC. VAT volume is strongly correlated with the formation of a pseudocyst and with systemic inflammatory response syndrome in patients with acute pancreatitis and high VAT volume may lead to severe acute pancreatitis.

Abstract
INTRODUCTION Obesity is an independent risk factor for severe acute pancreatitis, though the mechanisms underlying this association are unknown. The powerful anti-inflammatory adipokine adiponectin is decreased in obesity. We recently showed that the severity of pancreatitis in obese mice is inversely related to circulating adiponectin levels, and therefore hypothesized that adiponectin upregulation would attenuate the severity of pancreatitis in obese mice. METHODS Forty congenitally obese mice were studied. Seven days prior to study, 20 mice received a single tail vein injection of adenovirus expressing recombinant murine adiponectin (APN; 2 × 10⁸ plaque forming unit (pfu)), and the remainder received a control adenoviral vector expressing β-galactosidase (β-gal; 2 × 10⁸ pfu). Half of the mice in each group had pancreatitis induced by cerulein injection (50 mcg/kg IP hourly for 6 h). The other half received saline on the same schedule. Serum APN concentration and pancreatic tissue concentrations of interleukin (IL)-6, IL-1β, and MCP-1 were measured by ELISA. Histologic pancreatitis score was calculated based on the degree of inflammation (0-4), edema (0-4), and vacuolization (0-4). Data were analyzed by ANOVA and Tukey's tests; p < 0.05 was considered significant. RESULTS No difference in body weight was observed between groups. Serum APN was significantly upregulated in the APN group compared with the β-gal group. Pancreatic tissue concentration of IL-6 was significantly decreased in the APN group compared with the β-gal group. No change either in pancreatic tissue concentration of IL-1β and MCP-1 or in the severity of histologic pancreatitis were observed. CONCLUSION Adiponectin upregulation modulates the pancreatic cytokine milieu but does not attenuate pancreatitis in this model of mild acute pancreatitis.

Abstract
OBJECTIVES Adipocytes of peripancreatic and intrapancreatic adipose tissue secret adipocytokines such as leptin, adiponectin, and resistin. For resistin, a role as an early predictor of peripancreatic necrosis and clinical severity in acute pancreatitis has been reported. It was the aim of this study to investigate whether the adipocytokine visfatin is able to serve as an early marker predicting peripancreatic necrosis and clinical severity. METHODS A total of 50 patients (20 females and 30 males) with acute pancreatitis were included in this noninterventional, prospective, and monocentric cohort study on diagnostic accuracy. Clinical severity was classified by the Ranson score and APACHE-II (Acute Physiology and Chronic Health Evaluation II) score. Pancreatic and peripancreatic necrosis were quantified by the computed tomography-based Balthazar score, the Schroeder score, and the pancreatic necrosis score. Visfatin was measured at admission and daily for 10 days by enzyme-linked immunosorbent assay (ELISA). RESULTS Visfatin values were significantly and positively correlated with clinical severity (APACHE-II score and Ranson score) and with clinical end points such as death and need for interventions. Admission visfatin levels were significantly elevated in patients with higher pancreatic and extrapancreatic necrosis scores. It was shown by receiver operator characteristics that admission visfatin concentration provides a positive predictive value of 93.3% in predicting the extent of peripancreatic necrosis (area under the curve (AUC): 0.89, P<0.001, sensitivity: 93.3%, specificity: 81.8%, likelihood ratio: 5.1, post-test probability: 93%) by using a cutoff value of 1.8 ng/ml. CONCLUSIONS Admission visfatin concentration serves as an early predictive marker of peripancreatic necrosis and clinical severity in acute pancreatitis. Visfatin may have potential for clinical use as a new and diagnostic serum marker.

Abstract
OBJECTIVES Peripancreatic necrosis determines clinical severity in acute pancreatitis. Early markers predicting peripancreatic necrosis and clinical severity are lacking. Because adipocytes of peripancreatic adipose tissue secret highly active adipocytokines, the aim of the study was to investigate whether adipocytokines are able to serve as early markers predicting peripancreatic necrosis and clinical severity. METHODS A total of 50 patients (20 women, 30 men) with acute pancreatitis were included in this noninterventional, prospective, and monocentric cohort study on diagnostic accuracy. Clinical severity was classified by the Ranson score and the APACHE (Acute Physiology And Chronic Health Evaluation) II score. Pancreatic and peripancreatic necrosis were quantified by using the computed tomography-based Balthazar score, the Schroeder score, and the pancreatic necrosis score. Adiponectin, leptin, and resistin were measured at admission and daily for at least 10 days by enzyme-linked immunosorbent assay. RESULTS In contrast to admission C-reactive protein values, admission resistin values were significantly correlated with clinical severity and even with clinical end points such as death and need for interventions. Admission resistin levels were significantly elevated in patients with higher pancreatic and extrapancreatic necrosis scores. It was shown by receiver-operator characteristics that admission resistin concentration provides a positive predictive value of 89% in predicting the extent of peripancreatic necrosis (area under the curve, 0.8; P=0.002; sensitivity, 80%; specificity, 70%) by using a cutoff value of 11.9 ng/ml. CONCLUSIONS Admission resistin concentration serves as an early predictive marker of peripancreatic necrosis and clinical severity in acute pancreatitis. Resistin may have potential for clinical use as a new and diagnostic serum marker.

Usefulness of assessing circulating levels of resistin, ghrelin, and IL-18 in alcoholic acute pancreatitis. Dig Dis Sci 2010; 55:2982-7.

Abstract
OBJECTIVES Acute pancreatitis (AP) is a severe inflammatory disease with high mortality and morbidity rates. We have previously demonstrated that resistin may represent an early marker of inflammation in AP. It was also revealed that ghrelin may have anti-inflammatory potential. However, the role of adipohormones in AP-resistin and ghrelin as well as the proinflammatory cytokine interleukin (IL)-18-has not yet been fully elucidated. METHODS The study group comprised 32 patients with alcoholic AP and 30 controls matched for age, sex, and body mass index (BMI). In all cases AP was classified as grade C according to Balthazar's computed tomography (CT) score and as severe (3 points) according to Ranson's criteria. Serum levels of resistin, ghrelin, and IL-18 were measured on first, third, and fifth day of hospitalization by enzyme-linked immunosorbent assay (ELISA). RESULTS On first day of hospitalization the mean serum resistin concentration in AP patients was significantly higher than in controls (P < 0.05) and further increased on third and fifth day of hospitalization (17.4 ± 4.23 ng/ml and 25.8 ± 8.14 ng/ml, respectively). On first day of hospitalization the mean serum IL-18 concentration in AP patients was significantly higher than in controls (P < 0.05), on third day its level further increased, and on fifth day it decreased to a level similar to that observed on admission. The serum ghrelin concentrations on first, third, and fifth day of hospitalization were comparable, and significantly higher than in controls (P < 0.01). Significant correlation between C-reactive protein (CRP) and resistin levels (r = 0.43; P < 0.05) and between CRP and IL-18 (r = 0.58; P <0.05) on day of admission was found. CONCLUSIONS Serum concentration of IL-18 and resistin may contribute to inflammatory response and may be useful as an early marker of inflammation in AP. We also suspect that ghrelin affects the course of AP and plays an important role in inflammatory response.

Abstract
BACKGROUND Resistin and visfatin, hormones produced by adipose tissue, have pro-inflammatory potential; however, their role in acute pancreatitis (AP) has been investigated only rarely. METHODS The study group comprised 32 patients with alcoholic AP and 30 controls. In all cases AP was classified as C according to Balthazar's CT score and as severe according to Ranson's criteria. The serum level of visfatin, resistin, and interleukin(IL)-8 immunoassays were measured by ELISA on admission and on the third and fifth day of hospitalization. RESULTS On the admission day serum resistin and IL-8 concentrations in AP patients were significantly higher than in controls and they further increased on the third and fifth day of hospitalization. On the admission day serum visfatin levels in AP patients were significantly higher than in controls and further increased on the third day of hospitalization. On the fifth day the levels decreased; however, they were still higher than on admission. The correlation between visfatin and resistin as well as between C-reactive protein and visfatin, resistin and IL-8 levels has been found. CONCLUSION In the course of AP, visfatin and resistin levels increase in parallel with C-reactive protein. We speculate that those parameters may provide an additional tool for the prognosis and monitoring of AP. and IAP.

Abstract
OBJECTIVES Obesity markedly increases the risk of severe acute pancreatitis (SAP), possibly through the action of adipokines. We tested the hypothesis that serum adiponectin, the primary anti-inflammatory adipokine, is associated with functional polymorphisms in the adiponectin gene (ADIPOQ) and inversely associated with SAP. METHODS Severe AP was defined as the presence of remote organ failure. ADIPOQ polymorphisms rs2241766T>G and rs1501299G>T were evaluated by DNA sequencing. Serum samples were assayed using a Luminex assay (Luminex, Austin, Tex). RESULTS One hundred thirty-three patients with AP and 94 healthy controls were ascertained. Adiponectin levels were measured in 60 patients with early serum samples (27 patients with mild AP and 33 patients with SAP). Adiponectin levels from days 1 to 3 were inversely correlated with body mass index (BMI) (rho = -0.49; P = 0.002) and were significantly lower for patients with SAP (median, 3.74 microg/mL) than those with mild AP (6.58 microg/mL; P = 0.02). Neither ADIPOQ polymorphism affected susceptibility to or severity of AP. A receiver operating characteristics curve using adiponectin levels as the severity predictor provided an area under the curve of 0.75. CONCLUSIONS Serum adiponectin levels in patients with AP are inversely correlated with BMI and organ dysfunction. Further studies are needed to determine whether adiponectin is a marker of low BMI or if it provides significant protection from SAP.

Abstract
BACKGROUND Visceral adipose tissues secret a variety of adipokines; however, it is not known whether they are present in the peritoneal fluid. It was the aim of this study to investigate peritoneal fluid concentrations of novel (cartonectin, omentin) and classical adipokines (leptin, adiponectin, resistin, visfatin) in patients with ascites. MATERIAL AND METHODS Ninety-six patients (71 men and 25 women) undergoing paracentesis were included. Of these, 76 suffered from liver cirrhosis. Adipokines were measured by enzyme-linked immunosorbent assay or Western blot. RESULTS Each adipokine was detected in ascites with a broad range. Serum-ascites ratios (SAR) correlated with clinical and laboratory parameters. The main variables influencing peritoneal fluid adipokine concentrations were body mass index (BMI), local inflammation, systemic inflammation and serum adipokine concentrations. Resistin was significantly higher in patients with peritonitis and showed a positive correlation with peripheral leucocytes (white blood cell count). Leptin was correlated with the underlying disease. Visfatin correlated with peripheral white blood cell and C-reactive protein levels. Omentin expression was correlated with ascitic leucocyte count, ascitic albumin concentration and low albumin SAR. BMI was correlated positively with ascitic leptin levels and cartonectin protein levels. CONCLUSIONS Peritoneal fluid adipokine concentrations are characterized by individual SARs, depend on the presence of peritonitis, and correlate with underlying disease, BMI and systemic inflammation. The data open a new field of research on the role of the peritoneum and visceral adipokines in gastrointestinal diseases.

Abstract
BACKGROUND Resistin is an adipokine, which displays proinflammatory properties. Thus, it is likely that resistin can influence the course of chronic pancreatitis, and/or that chronic pancreatitis may affect the serum resistin concentration. GOALS The aim of the present study was to determine the serum resistin concentration in patients with chronic pancreatitis and to analyze the relationship between serum resistin concentration and serum concentrations of leptin (proinflammatory adipokine) and adiponectin (anti-inflammatory adipokine). STUDY A total of 23 male, nondiabetic patients with chronic pancreatitis of alcoholic origin and 16 healthy subjects were examined. Fasting blood samples were collected from patients in both groups. Serum resistin concentration was assayed by enzyme-linked immunosorbent assay. Serum adiponectin, leptin, and insulin concentrations were determined by radioimmunoassay. RESULTS Serum resistin concentration was significantly higher in patients with chronic pancreatitis as compared with control subjects. In contrast, patients with chronic pancreatitis had lower serum leptin and insulin concentrations than healthy subjects. There were no statistically significant differences in serum adiponectin concentration between patients with pancreatitis and healthy subjects. CONCLUSIONS The results presented in this paper indicate that chronic pancreatitis in human is associated with the increase in serum resistin concentration and with the decrease in serum leptin and insulin concentrations. It can be supposed that resistin, by stimulation of tumor necrosis factor-alpha synthesis in blood mononuclear cells and in macrophages, increases the concentration of tumor necrosis factor-alpha, which in turn activates stellate cells. Activated stellate cells can produce collagen, eventually resulting in the development of pancreatic fibrosis.

Abstract
Obesity is associated with increased severity of acute pancreatitis (AP). The cytokines IL-18 and IL-12 are elevated in patients with AP, and IL-18 levels are high in obesity. We aimed to develop a pathologically relevant model to study obesity-associated severe AP. Lean WT and obese leptin-deficient ob/ob mice received two injections of IL-12 plus IL-18. Survival, pancreatic inflammation, and biochemical markers of AP were measured. Dosing with IL-12 plus IL-18 induced 100% lethality in ob/ob mice; no lethality was observed in WT mice. Disruption of pancreatic exocrine tissue and acinar cell death as well as serum amylase and lipase levels were significantly higher in ob/ob than in WT mice. Edematous AP developed in WT mice, whereas obese ob/ob mice developed necrotizing AP. Adipose tissue necrosis and saponification were present in cytokine-injected ob/ob but not in WT mice. Severe hypocalcemia and elevated acute-phase response developed in ob/ob mice. The cytokine combination induced high levels of regenerating protein 1 and pancreatitis-associated protein expression in the pancreas of WT but not of ob/ob mice. To differentiate the contribution of obesity to that of leptin deficiency, mice received short- and long-term leptin replacement therapy. Short-term leptin reconstitution in the absence of major weight loss did not protect ob/ob mice, whereas leptin deficiency in the absence of obesity resulted in a significant reduction in the severity of the pancreatitis. In conclusion, we developed a pathologically relevant model of AP in which obesity per se is associated with increased severity.
