Abstract
Background Predicting severe acute pancreatitis (AP) in the early clinical stage is important for low morbidity and mortality. Delta neutrophil index (DNI) is used to detect infection and inflammation, but no previous studies have evaluated the usefulness of DNI as an early predictor of progression to severe AP (SAP). Methods The medical records of patients who were diagnosed with AP at the emergency department (ED) of Wonju Severance Christian Hospital from January 2012 to August 2016 were retrospectively reviewed. The initial DNI obtained in the ED was compared with other inflammatory markers to predict SAP. Multivariate logistic regression was used for statistical analysis. Results Of the 209 cases included in the analysis, 13 were classified as SAP. Compared to the DNI of the mild to moderately SAP group, that in the SAP group was considerably higher. The DNI showed a positive correlation with the Atlanta classification and bedside index of severity in AP. Using multivariate logistic regression analysis, DNI was an independent predictor of early SAP detection (odds ratio 1.122, 95% CI 1.045-1.205, p = 0.001). Among the biomarkers, DNI had the highest predictive value for SAP. Conclusions The DNI measured in the ED at presentation is a potentially useful adjunctive marker to predict SAP.

Plasma mtDNA Analysis Aids in Predicting Pancreatic Necrosis in Acute Pancreatitis Patients: A Pilot Study. Dig Dis Sci 2018; 63:2975-2982. [PMID: 30094625 DOI: 10.1007/s10620-018-5227-9] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/22/2018] [Accepted: 07/26/2018] [Indexed: 12/12/2022]
Abstract
BACKGROUND Specific plasma biomarkers in predicting pancreatic necrosis (PNec) are needed in treating acute pancreatitis (AP). AIMS To investigate the prognostic value of plasma mitochondrial DNA fragments (mtDNA) in patient with AP for PNec. METHODS AP patients with symptoms onset within 72 h were prospectively enrolled from June 2015 through June 2017 and were assessed for PNec using contrast-enhanced CT scan. Plasma mtDNA concentration (specific mitochondrial gene ND1) was measured using qRT-PCR. RESULTS Of the 74 AP patients included, significant higher median level of plasma mtDNA was found in severe AP patients than in mild AP patients and healthy controls, but not in moderately severe AP patients. Patients with PNec had higher level of plasma mtDNA than those without PNec (774.2 [IQR 397.6-2205.0] vs. 169.5 [IQR 73.6-683.4] pg/ml, P < 0.05). The area under the receiver operator characteristic curve (ROC-AUC) of mtDNA for predicting PNec was higher than that of CRP (0.813 [95% CI 0.705-0.895] vs. 0.678 [95% CI 0.558-0.783]). Using a cutoff value of 302.5 pg/ml, the sensitivity and specificity for diagnosing PNec were 90.9 and 68.3%, respectively. Finally, plasma mtDNA levels decreased significantly after continuous renal replacement therapy (717.7 [IQR 307.00-1370.00] vs. 237.5 [IQR 117.20-464.80] pg/ml, P < 0.01). CONCLUSIONS Elevated plasma mtDNA content in AP patients may be used as a more accurate early predictor of PNec in contrast to traditional CRP.

Abstract
BACKGROUND & AIMS The Food and Drug Administration approved eluxadoline for the treatment of diarrhea-predominant irritable bowel syndrome despite cases of pancreatitis in early stage trials. We investigated the frequency of pancreatitis attributed to eluxadoline in postmarketing surveillance. METHODS We extracted reports on eluxadoline submitted to the Federal Adverse Event Reporting System from January through September 2016. We collected data on patient age and sex, event date, reporting entity (consumer, physician, pharmacist, legal worker, or other), medications, dosages, presumed role in the event (coinciding, primary, or secondary suspect), treatment indication, and outcome (death, life threatening, hospitalization, disability, or other).We compared data for eluxadoline with data from antidiarrheals, oxycodone, and rifaximin using the κ2 test, Kruskal-Wallis rank test, and analysis of variance; findings with P < .05 were considered statistically significant. RESULTS Pancreatitis accounted for 16.4% of the 597 reports of adverse events linked to eluxadoline; 53 cases required hospitalization. Pancreatitis was listed as treatment complication of other agents in significantly lower proportions of cases (loperamide, 0.3%; diphenoxylate, 0.4%; oxycodone, 0.2%; rifaximin, 0.5%), with 75% of these submissions not considering the agent as causal. CONCLUSIONS In an analysis of reports on eluxadoline submitted to the Federal Adverse Event Reporting System, we confirmed a previously reported risk of pancreatitis associated with eluxadoline. The need for hospitalization in at least half of these instances and a recent report of 2 fatalities should prompt reassessments of the agent's risk-benefit ratio.

Abstract
AIM To determine the prevalence, characteristics and clinical course of pancreatic cystic neoplasms (PCNs) in liver transplantation (LT) recipients.
METHODS We retrospectively studied consecutive patients who underwent LT between January 1998 to April 2016. Clinical and laboratory data were obtained from patient medical records. Imaging findings on computed tomography and magnetic resonance cholangiopancreatography were reviewed by two radiologists.
RESULTS During the study period, 872 patients underwent cadaveric LT. Pancreatic cysts were identified in 53/872 (6.1%) and 31/53 (58.5%) were PCNs [28 intraductal papillary mucinous neoplasm (IPMN), 2 mucinous cystic neoplasm (MCN), 1 serous cystadenoma]. Patients with PCNs exhibited less male predominance (55% vs 73%, P = 0.03) compared to patients without pancreatic cysts. Thirteen patients (42%) were diagnosed with PCN pre-LT while 18 patients (58%) developed PCN post-LT. The median size of PCNs was 13mm [interquartile range (IQR) 10-20 mm]. All IPMNs were side-branch type. Most PCNs were found in the head and body of pancreas (37% each), followed by the tail (25%). Five patients underwent further evaluation with endoscopic ultrasound. Progress imaging was performed on 81% of patients. PCNs remained stable in size and number in all but 2 patients. During a median follow up of 39 mo (IQR 26-58 mo), the 2 (6%) patients with MCN underwent pancreatectomy. No PCN patient developed pancreatic adenocarcinoma, while 5 died from illnesses unrelated to the PCN. Among patients without PCN, 1/841 (0.1%) developed pancreatic adenocarcinoma.
CONCLUSION The prevalence of PCNs in LT recipients was similar to the general population (3.6%, 31/872). Side-branch IPMNs do not appear to have accelerated malignant potential in post-LT patients, indicating the current surveillance guidelines are applicable to this group.

Abstract
There is a great need for early verification of the severity of acute pancreatitis (AP). The early stage of pathogenesis of AP is characterized by endothelial dysfunction which could be determined by wavelet analysis of skin temperature (WAST) technique. The aim is to investigate whether the dysregulation of microvascular tone caused by endothelial dysfunction and detected by WAST can be a significant indicator in early differential diagnosis of AP severity. The WAST performed in the frequency range of 0.0095-0.02 Hz during the contralateral cold test. Forty nine patients with AP aged 19-65 participated in this study. The control group included 12 healthy volunteers aged 20-65. Dysregulation of vascular tone during the contralateral cold test was observed in all patients with AP. The basal amplitudes of skin temperature oscillations in patients with AP were much lower than in healthy volunteers and progressively decreased as the disease severity increased. In patients with mild and moderate AP only the vasodilator component is destroyed, but vasoconstriction still operates. In patients with severe AP both mechanisms of endothelial vascular tone regulation are destroyed. Patients with AP have abnormal microvascular reactions related to the endothelial mechanism of vascular tone regulation. Based on the initial values of amplitudes and the indices of vasoconstriction and postcold vasodilatation, the WAST method makes it possible to evaluate two related but different characteristics of the endothelial dysfunction in patients with AP on admission which can be a significant indicator in early differential diagnosis of AP severity.

Abstract
BACKGROUND In recent years, a step-up approach based on minimally invasive techniques was recommended by latest guidelines as initial invasive treatment for infected pancreatic necrosis (IPN). In this study, we aimed to describe a novel step-up approach for treating IPN consisting of four steps including negative pressure irrigation (NPI) and endoscopic necrosectomy (ED) as a bridge between percutaneous catheter drainage (PCD) and open necrosectomy METHODS: A retrospective review of a prospectively collected internal database of patients with a diagnosis of IPN between Jan, 2012 to Dec, 2012 at a single institution was performed. All patients underwent the same drainage strategy including four steps: PCD, NPI, ED and open necrosectomy. The demographic characteristics and clinical outcomes of study patients were analyzed. RESULTS A total of 71 consecutive patients (48 males and 23 females) were included in the analysis. No significant procedure-related complication was observed and the overall mortality was +21.1 % (15 of 71 patients). Seven different strategies like PCD+ NPI, PCD+NPI+ED, PCD+open necrosectomy, etcetera, were applied in study patients and a half of them received PCD alone. In general, each patient underwent a median of 2 drainage procedures and the median total drainage duration was 11 days (interquartile range, 6-21days). CONCLUSIONS This four-step approach is effective in treating IPN and adds no extra risk to patients when compared with other latest step-up strategies. The two novel techniques (NPI and ED) could offer distinct clinical benefits without posing unanticipated risks inherent to the procedures.

Abstract
This is a case report of endoscopic ultrasound guided transmural drainage of a large infected pancreatic necrosis. The infected necrosis was treated by placement of a fully covered metal stent with subsequent endoscopic necrosectomy to remove solid debris. The case is notable for the fact that the patient developed infection of a long-standing and previously stable area of walled-off pancreatic necrosis 2 years after it formed. We believe this is the longest time ever reported between necrotizing pancreatitis and the development of infected pancreatic necrosis.

Abstract
Knowledge about acute pancreatitis has increased recently in both the medical and veterinary fields. Despite this expansion of knowledge, there are very few studies on treatment interventions in naturally occurring disease in dogs. As a result, treatment recommendations are largely extrapolated from experimental rodent models or general critical care principles. General treatment principles involve replacing fluid losses, maintaining hydrostatic pressure, controlling nausea and providing pain relief. Specific interventions recently advocated in human medicine include the use of neurokinin-1 antagonists for analgesia and early interventional feeding. The premise for early feeding is to improve the health of the intestinal tract, as unhealthy enterocytes are thought to perpetuate systemic inflammation. The evidence for early interventional feeding is not supported by robust clinical trials to date, but in humans there is evidence that it reduces hospitalisation time and in dogs it is well tolerated. This article summarises the major areas of management of acute pancreatitis in dogs and examines the level of evidence for each recommendation.

Abstract
BACKGROUND AND OBJECTIVES Chinese herbal drug Da-Cheng-Qi decoction (DCQD) has been widely used for decades to treat acute pancreatitis (AP). Previous trials are mostly designed to state the potential mechanisms of the therapeutic effects rather than to detect its whole effect on metabolism. This study aimed to investigate the efficacy of DCQD on metabolism in AP. METHODS Twenty-two male adult Sprague-Dawley rats were randomized into three groups. AP was induced by retrograde ductal infusion of 3.5% sodium taurocholate solution in DCQD and AP group, while 0.9% saline solution was used in sham operation (SO) group. Blood samples were obtained 12 h after drug administration and a 600 MHz superconducting Nuclear Magnetic Resonance (NMR) spectrometer was used to detected plasma metabolites. Principal Components Analysis (PCA) and Partial Least Squares-Discriminant Analysis after Orthogonal Signal Correction (OSC-PLS-DA) were applied to analyze the Longitudinal Eddy-delay (LED) and Carr-Purcell-Meiboom-Gill (CPMG) spectra. RESULTS Differences in concentrations of metabolites among the three groups were detected by OSC-PLS-DA of 1HNMR spectra (both LED and CPMG). Compared with SO group, DCQD group had higher levels of plasma glycerol, glutamic acid, low density lipoprotein (LDL), saturated fatty acid (FA) and lower levels of alanine and glutamine, while the metabolic changes were reversed in the AP group. CONCLUSIONS Our results demonstrated that DCQD was capable of altering the changed concentrations of metabolites in rats with AP and 1HNMR-based metabolomic approach provided a new methodological cue for systematically investigating the efficacies and mechanisms of DCQD in treating AP.

Abstract
Critical acute pancreatitis (CAP) has recently emerged as the most ominous severity category of acute pancreatitis (AP). As such there have been no studies specifically designed to evaluate predictors of CAP. In this study, we aimed to evaluate the accuracy of 4 parameters (Acute Physiology and Chronic Health Evaluation [APACHE] II score, C-reactive protein [CRP], D-dimer, and intra-abdominal pressure [IAP]) for predicting CAP early after hospital admission. During the study period, data on patients with AP were prospectively collected and D-dimer, CRP, and IAP levels were measured using standard methods at admission whereas the APACHE II score was calculated within 24 hours of hospital admission. The receiver-operating characteristic (ROC) curve analysis was applied and the likelihood ratios were calculated to evaluate the predictive accuracy. A total of 173 consecutive patients were included in the analysis and 47 (27%) of them developed CAP. The overall hospital mortality was 11% (19 of 173). APACHE II score ≥11 and IAP ≥13 mm Hg showed significantly better overall predictive accuracy than D-dimer and CRP (area under the ROC curve-0.94 and 0.92 vs. 0.815 and 0.667, correspondingly). The positive likelihood ratio of APACHE II score is excellent (9.9) but of IAP is moderate (4.2). The latter can be improved by adding CRP (5.8). In conclusion, of the parameters studied, APACHE II score and IAP are the best available predictors of CAP within 24 hours of hospital admission. Given that APACHE II score is rather cumbersome, the combination of IAP and CRP appears to be the most practical way to predict critical course of AP early after hospital admission.

Abstract
Modeling visceral pain requires an appreciation of the underlying neurobiology of visceral sensation, including characteristics of visceral pain that distinguish it from pain arising from other tissues, the unique sensory innervation of visceral organs, the functional basis of visceral pain, and the concept of viscero-somatic and viscero-visceral convergence. Further, stimuli that are noxious when applied to the viscera are different than stimuli noxious to skin, muscle, and joints, thus informing model development and assessment. Visceral pain remains an important and understudied area of pain research and basic science knowledge and mechanisms acquired using animal models can translate into approaches that can be applied to the study and development of future therapeutics.

Abstract
Acute pancreatitis is a known post-operative complication, commonly after abdominal surgery rather than total knee arthroplasty. When complications occur, post total knee arthroplasty, they tend to be cardiovascular and neurological events, rarely involving the gastrointestinal system. Therefore, when gastrointestinal complications occur, especially if they present with atypical symptoms, this tends to result in a delay in diagnosis. We present a case of acute pancreatitis post simultaneous bilateral total knee arthroplasty in a patient with risk factors like alcoholism and hypercholesterolaemia. Its atypical presentation of only persistent tachycardia, without abdominal pain, was misleading and the resultant delay in treatment dangerous. Therefore, it is important to consider acute pancreatitis as a differential diagnosis in a patient with persistent tachycardia post total knee arthroplasty, especially if he has risk factors for the condition.

Abstract
PURPOSE OF REVIEW Enteral nutrition has emerged as one of the most effective treatments in the early management of patients with acute pancreatitis. The original rationale for nutrition in acute pancreatitis, dating back to the mid-20th century, was to provide full nutritional requirements but avoid stimulating exocrine pancreatic secretion. The purpose of this article is to review the recent clinical studies of enteral nutrition in acute pancreatitis to revise the rationale and develop a contemporary conceptual framework for nutritional management of this disease. RECENT FINDINGS Several recent randomized controlled trials dispel the outdated concept of 'pancreatic rest', which equates with gut neglect, and offer 'gut rousing' as a preferred concept. The new concept postulates that gastrointestinal (dys)function has a discernible impact on the outcomes of patients with acute pancreatitis. Further, timely administration of appropriate intraluminal modalities prevents or mitigates the gastrointestinal dysfunction. SUMMARY Nutritional management in acute pancreatitis should aim primarily at maintaining the gastrointestinal function. Providing full nutritional requirements and avoiding pancreatic exocrine stimulation should be considered as secondary aims.

Abstract
BACKGROUND Surgical decompression is widely considered as an important treatment in patients with severe acute pancreatitis (SAP) and abdominal compartment syndrome (ACS). Until now, the indication and optimal time of decompression remain unknown, and no experimental data exist, although extremely high mortality has been repeatedly reported in these patients. The aim of this study was to evaluate the effects of three different time points for decompression in a 24-hour lasting porcine model. METHODS Following baseline registrations, 32 animals were divided into four groups (8 animals each group) as follows: one SAP-alone group and three SAP + ACS groups, which received decompression at 6, 9, and 12 hours. We used a N2 pneumoperitoneum to increase the intra-abdominal pressure to 25 mm Hg and retrograde intra-ductal infusion of sodium taurocholate to induce SAP. Global hemodynamic profiles, urine output, systemic oxygenation, and serum biochemical parameters of the animals were studied. At the end of the experiment, histologic examination of the intestine and lung was performed. RESULTS The survival time of the 12-hour group was significantly shortened (p = 0.037 vs. 9 hours and p = 0.008 vs. 6 hours). In SAP + ACS animals, decompression at 6 hours restored systemic hemodynamics, oxygen-derived parameters, organ function, and inflammatory intensity to a level comparable with that of the SAP-alone group. In contrast, animals in the 9 hours and 12 hours developed more severe hemodynamic and organ dysfunction. The histopathologic analyses also revealed higher grade injury of the intestine and lung in animals receiving delayed decompression. CONCLUSION Well-timed decompression in a porcine model of SAP incorporating 25-mm Hg intra-abdominal hypertension/ACS was associated with significantly reduced mortality, improved systemic hemodynamics and organ function, as well as alleviated histologic injury and inflammatory intensity. According to our results and previous reports, both too early and too late decompression should be avoided owing to significant morbidity for the former and unfavorable outcomes for the latter.

Abstract
Acute lung injury (ALI) is an inflammatory disease with a high mortality rate. Although typically seen in individuals with sepsis, ALI is also a major complication in severe acute pancreatitis (SAP). The pathophysiology of SAP-associated ALI is poorly understood, but elevated serum levels of IL-6 is a reliable marker for disease severity. Here, we used a mouse model of acute pancreatitis-associated (AP-associated) ALI to determine the role of IL-6 in ALI lethality. Il6-deficient mice had a lower death rate compared with wild-type mice with AP, while mice injected with IL-6 were more likely to develop lethal ALI. We found that inflammation-associated NF-κB induced myeloid cell secretion of IL-6, and the effects of secreted IL-6 were mediated by complexation with soluble IL-6 receptor, a process known as trans-signaling. IL-6 trans-signaling stimulated phosphorylation of STAT3 and production of the neutrophil attractant CXCL1 in pancreatic acinar cells. Examination of human samples revealed expression of IL-6 in combination with soluble IL-6 receptor was a reliable predictor of ALI in SAP. These results demonstrate that IL-6 trans-signaling is an essential mediator of ALI in SAP across species and suggest that therapeutic inhibition of IL-6 may prevent SAP-associated ALI.

Abstract
OBJECTIVE Several international guidelines concerning the treatment of acute pancreatitis has been published during the last decades. However, Scandinavian guidelines are still lacking. The aim of the present study is to identify current treatment strategies for acute pancreatitis in Sweden and to evaluate if there is a need for improvement and the role of guidelines. MATERIAL AND METHODS A questionnaire was e-mailed to the surgical departments at all Swedish hospitals (n = 58) managing patients with acute pancreatitis. Comparisons were made both between university and non-university hospitals, and between hospitals with more versus less than 150,000 persons in the primary catchment population. RESULTS Fifty-one hospitals responded (88%). In median, 65 (12-200) patients with acute pancreatitis are treated yearly at each hospital. Of 51 hospitals, 18 perform a severity classification, with APACHE II being the most commonly used. A majority are of the opinion that a scoring system is not better than the judgment of a senior consultant. In severe acute pancreatitis, 29/48 routinely administer antibiotics, 29/48 use enteral nutrition, and 25/49 have a standardized follow-up plan. The majority considered administration of intravenous fluids as the most important treatment in severe acute pancreatitis. After mild gallstone-induced acute pancreatitis, the corresponding response was cholecystectomy, especially at larger hospitals (p = 0.002). Of 47, 42 are interested in developing a Scandinavian quality register. CONCLUSIONS The results from this first Swedish national survey provide an insight into current traditions of treatment of acute pancreatitis and points, for example, at the lack of early severity stratification. A majority of hospitals are interested in developing a quality register in acute pancreatitis.

Abstract
OBJECTIVE Hypertonic saline (HTS) solution resuscitation has been used in a variety of clinical settings. The aim of this study was to assess the effect of HTS resuscitation on hemodynamics, systemic oxygenation, and organ damage in a porcine model of severe acute pancreatitis. METHODS Eighteen anesthetized and mechanically ventilated pigs were divided into 3 groups: HTS group, lactated Ringer solution (LR) group, and sham-operated group. Severe acute pancreatitis was induced in the first 2 groups by injecting 5% sodium taurocholate into the pancreatic duct, and the investigation period was 12 hours. Hemodynamic parameters, urine output, oxygenation parameters, and serum parameters were recorded consecutively. Finally, histologic examinations of the kidney, intestine, pancreas, and lung were performed. RESULTS In the HTS group, cardiac output decreased less significantly compared with the LR group. Furthermore, aspartate aminotransferase, creatinine, and lactate levels increased significantly in all animals with severe acute pancreatitis, but the increasing tendency was slower in the HTS group. Nevertheless, the histopathologic analysis revealed similar injuries of the kidney, intestine, pancreas, and lung between the HTS and LR groups. CONCLUSIONS Early administration of HTS generally improves hemodynamics and peripheral oxygenation. Despite these normalized parameters, organ damage could not be diminished to a significant degree during observation.

Abstract
Acute pancreatitis (AP) is a common and potentially lethal acute inflammatory process. Although the majority of patients have a mild episode of AP, 10%-20% develop a severe acute pancreatitis (SAP) and suffer systemic inflammatory response syndrome (SIRS) and/or pancreatic necrosis. The main aim of this article is to review the set of events, first localized in the pancreas, that lead to pancreatic inflammation and to the spread to other organs contributing to multiorganic shock. The early pathogenic mechanisms in SAP are not completely understood but both premature activation of enzymes inside the pancreas, related to an impaired cytosolic Ca2+ homeostasis, as well as release of pancreatic enzymes into the bloodstream are considered important events in the onset of pancreatitis disease. Moreover, afferent fibers within the pancreas release neurotransmitters in response to tissue damage. The vasodilator effects of these neurotransmitters and the activation of pro-inflammatory substances play a crucial role in amplifying the inflammatory response, which leads to systemic manifestation of AP. Damage extension to other organs leads to SIRS, which is usually associated with cardiocirculatory physiology impairment and a hypotensive state. Hypotension is a risk factor for death and is associated with a significant hyporesponsiveness to vasoconstrictors. This indicates that stabilization of the patient, once this pathological situation has been established, would be a very difficult task. Therefore, it seems particularly necessary to understand the pathological mechanisms involved in the first phases of AP to avoid damage beyond the pancreas. Moreover, efforts must also be directed to identify those patients who are at risk of developing SAP.
