Yang L, He C, Wang W. Association between neutrophil to high-density lipoprotein cholesterol ratio and disease severity in patients with acute biliary pancreatitis. Ann Med 2024; 56:2315225. [PMID: 38335727 PMCID: PMC10860409 DOI: 10.1080/07853890.2024.2315225] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Accepted: 02/02/2024] [Indexed: 02/12/2024] Open
Abstract
BACKGROUND The neutrophil to high-density lipoprotein cholesterol ratio (NHR) is independently associated with the severity of various diseases. However, its association with acute biliary pancreatitis (ABP) remains unknown. METHODS This study included 1335 eligible patients diagnosed with ABP from April 2016 to December 2022. Patients were divided into low- and high-NHR level groups using an optimal cut-off value determined utilizing Youden's index. Multivariate logistic regression analysis was used to investigate the correlation between NHR and ABP severity. Multivariate analysis-based limited restricted cubic spline (RCS) method was used to evaluate the nonlinear relationship between NHR and the risk of developing moderate or severe ABP. RESULTS In this study, multivariate logistic regression analysis indicated an independent association between NHR and ABP severity (p < .001). The RCS analysis showed a linear correlation between NHR and the risk of developing moderate or severe ABP (P for non-linearity > 0.05), and increased NHR was found to be independently associated with a more severe form of the disease. CONCLUSIONS Our study suggests that NHR is a simple and practical independent indicator of disease severity, serving as a potential novel predictor for patients with ABP.

Risk of pancreatitis and pancreatic carcinoma for anti-diabetic medications: findings from real-world safety data analysis and systematic review and meta-analysis of randomized controlled trials. Expert Opin Drug Saf 2024; 23:731-742. [PMID: 37986140 DOI: 10.1080/14740338.2023.2284992] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Accepted: 08/25/2023] [Indexed: 11/22/2023]
Abstract
BACKGROUND The existing evidence from pre- and post-marketing studies is conflicting on the risk of pancreatic events for anti-diabetic medications. RESEARCH DESIGN AND METHODS A retrospective case/non-case study was conducted by using spontaneous reports on pancreatic events for anti-diabetic medications from the FDA Adverse Event Reporting System (FAERS) and VigiBase. Proportional Reporting Ratio (PRR), Reporting Odds Ratio (ROR), and Information Component (IC) were calculated by a disproportionality analysis. Furthermore, PubMed, Google Scholar, Scopus, and ClinicalTrials.gov were systematically searched for randomized controlled trials (RCTs) on anti-diabetic drugs with pancreatic outcomes. RESULTS The FAERS data analysis found strong signals on incretin mimetics causing pancreatic events, with sitagliptin having the highest risk [PRR = 24.2, lower bound (LB) ROR = 24.4, IC025 = 4.4 for pancreatitis, and PRR = 15.4, LB ROR = 14.9, IC025 = 3.8 for pancreatic carcinoma]. Empagliflozin was the most pancreatitis-risk sodium-glucose co-transporter-2 inhibitor [PRR = 4.0, LB ROR = 3.5, IC025 = 1.8]. VigiBase reiterated these findings and identified some new signals for novel anti-diabetics. Meta-analysis revealed that the incidence of pancreatitis and pancreatic carcinoma with anti-diabetic medications was insignificant. However, compared to the placebo/active comparator, gliptins had a higher risk of acute pancreatitis (OR 1.44; 95% CI 1.03, 2.01; P = 0.03). CONCLUSION Evidence from the post-marketing safety data analysis identified a strong association between incretin mimetics and pancreatic events. Fewer events in RCTs may justify insignificant meta-analysis results.

Abstract
INTRODUCTION The objective of this study is to evaluate the role of minimally invasive surgery for the management of necrotising pancreatitis in acute settings and to propose tailor-made approaches to deal with various locations of pancreatic necrosis. PATIENTS AND METHODS Three hundred and thirteen patients underwent laparoscopic management of necrotising pancreatitis in this study period from January 2010 to June 2021, out of which 122 patients underwent minimally invasive necrosectomy for acute necrotising pancreatitis. The remaining 191 patients underwent laparoscopic internal drainage in the form of cystogastrostomy/cystojejunostomy for walled-off pancreatic necrosis. RESULTS Mean body mass index was 26.45 ± 3.78 kg/sqm. Mean operating time was 56.40 ± 20.48 min and mean blood loss was 120 ± 31.45 mL. Ten patients required reoperation (6 underwent open procedure and 4 underwent laparoscopic redo necrosectomy). Six patients died of multi-organ failure. The mean duration of return of bowel function was 5 ± 1.8 days. The mean length of hospital stay after surgery was 10.19 ± 7.09 days. There were no major wound-related complications. CONCLUSION A minimally invasive approach to pancreatic necrosectomy is safe and feasible with good outcomes in centres with advanced laparoscopic expertise. It requires not only careful case selection but also proper timing and the ideal route of access to achieve optimal outcomes.

Abstract
Severe gallstone pancreatitis (GSP) refractory to maximum conservative therapy has wide clinical variations, and its pathophysiology remains controversial. This Editorial aimed to investigate the pathophysiology of severe disease based on Opie’s theories of obstruction, the common channel, and duodenal reflux and describe its types. Severe GSP might be a hybrid disease with pathology polarized between acute cholangitis with mild pancreatitis (biliary type) and necrotizing pancreatitis uncomplicated with biliary tract disease (pancreatic type), in which hepatobiliary and pancreatic lesion severity is inversely related to the presence or absence of impacted ampullary stones. Severe GSP is caused by stones that are persistently impacted at the ampulla with biliopancreatic obstruction (biliary type), and probably, stones that are either temporarily lodged at the duodenal orifice or passed into the duodenum, thereby permitting reflux of bile or possible duodenal contents into the pancreas (pancreas type). When the status of the stones and the presence or absence of impacted ampullary stones with biliopancreatic obstruction are determined, the clinical course and outcome can be predicted. Gallstones represent the main cause of acute pancreatitis globally, and clinicians are expected to encounter GSP more often. Awareness of the etiology and pathogenesis of severe disease is mandatory.

Abstract
Introduction Intrapancreatic activation of trypsinogen caused by alcohol or high-fat intake and the subsequent autodigestion of the pancreas tissues by trypsin are indispensable events in the development of acute pancreatitis. In addition to this trypsin-centered paradigm, recent studies provide evidence that innate immune responses triggered by translocation of intestinal bacteria to the pancreas due to intestinal barrier dysfunction underlie the immunopathogenesis of acute pancreatitis. Although severe acute pancreatitis is often associated with pancreatic colonization by fungi, the molecular mechanisms linking fungus-induced immune responses to the development of severe acute pancreatitis are poorly understood. Leucine-rich repeat kinase 2 (LRRK2) is a multifunctional protein that mediates innate immune responses to fungi and bacteria. Mutations in Lrrk2 is a risk factor for Parkinson's disease and Crohn's disease, both of which are driven by innate immune responses to gut organisms. Discussion In this Minireview article, we discuss how activation of LRRK2 by the recognition of fungi induces severe acute pancreatitis.

Abstract
BACKGROUND Acute necrotizing pancreatitis is still related to high morbidity and mortality rates. Minimal-invasive treatment options, such as endoscopic necrosectomy, may decrease peri-interventional morbidity and mortality. This study aims to compare the initial operative with endoscopic treatment on long-term parameters, such as endocrine and exocrine functionality, as well as mortality and recurrence rates. METHODS We included 114 patients, of whom 69 were treated with initial endoscopy and 45 by initial surgery. Both groups were further assessed for peri-interventional and long-term parameters. RESULTS In the post-interventional phase, patients in the group of initial surgical treatment (IST) showed significantly higher rates of renal insufficiency (p < 0.001) and dependency on invasive ventilation (p < 0.001). The in-house mortality was higher in the surgical group, with 22% vs. 10.1% in the group of patients following initial endoscopic treatment (IET; p = 0.077). In long-term follow-up, the overall mortality was 45% for IST and 31.3% for IET (p = 0.156). The overall in-hospital stay and intensive care unit (ICU) stay were significantly shorter after IET (p < 0.001). In long-term follow-up, the prevalence of endocrine insufficiency was 50% after IST and 61.7% after IET (p = 0.281). 57.1% of the patients following IST and 16.4% of the patients following IET had persistent exocrine insufficiency at that point (p = < 0.001). 8.9% of the IET and 27.6% of the IST patients showed recurrence of acute pancreatitis (p = 0.023) in the long-term phase. CONCLUSION In our cohort, an endoscopic step-up approach led to a reduced in-hospital stay and peri-interventional morbidity. The endocrine function appeared comparable in both groups, whereas the exocrine insufficiency seemed to recover in the endoscopic group in the long-term phase. These findings advocate for a preference for endoscopic treatment of acute necrotizing pancreatitis whenever feasible.

Abstract
OBJECTIVE Phosphate is crucial for cellular repair after injury and may be important in recovery following acute pancreatitis (AP). This study aimed to evaluate the association between hypophosphatemia and severity of AP. METHODS Patients admitted with AP between 2014-2018 were identified and their records were retrospectively reviewed. Pancreatitis severity was defined using the modified Atlanta Criteria. Hypophosphatemia was defined as phosphate <2 mg/dL and was assessed at three time points: within one day, within two days, at any time during admission. The proportion of patients who developed severe AP was compared between patients with and without hypophosphatemia. RESULTS Of 312 patients, 30.1% (n = 94) developed severe AP. Hypophosphatemia occurred in 25.0% overall, within one day in 19.7%, and within two days in 20.0%. A higher proportion of patients with hypophosphatemia developed severe AP (overall: 47.4% vs. 24.4%, P < 0.001; one day: 47.4% vs. 23.9%, P = 0.004; two days: 42.9% vs. 24.5%, P = 0.01). Patients with hypophosphatemia within one day were also more likely to have ICU admission ( P < 0.001) and longer length of stay ( P < 0.001). CONCLUSIONS Early hypophosphatemia during an admission for AP was associated with increased AP severity, ICU admission, and longer length of stay.

Abstract
Translocation of gut bacteria into the pancreas promotes the development of severe acute pancreatitis (SAP). Recent clinical studies have also highlighted the association between fungal infections and SAP. The sensing of gut bacteria by pattern recognition receptors promotes the development of SAP via the production of proinflammatory cytokines; however, the mechanism by which gut fungi mediate SAP remains largely unknown. Leucine-rich repeat kinase 2 (LRRK2) is a multifunctional protein that regulates innate immunity against fungi via Dectin-1 activation. Here, we investigated the role of LRRK2 in SAP development and observed that administration of LRRK2 inhibitors attenuated SAP development. The degree of SAP was greater in Lrrk2 transgenic (Tg) mice than in control mice and was accompanied by an increased production of nuclear factor-kappaB-dependent proinflammatory cytokines. Ablation of the fungal mycobiome by anti-fungal drugs inhibited SAP development in Lrrk2 Tg mice, whereas the degree of SAP was comparable in Lrrk2 Tg mice with or without gut sterilization by a broad range of antibiotics. Pancreatic mononuclear cells from Lrrk2 Tg mice produced large amounts of IL-6 and TNF-α upon stimulation with Dectin-1 ligands, and inhibition of the Dectin-1 pathway by a spleen tyrosine kinase inhibitor protected Lrrk2 Tg mice from SAP. These data indicate that LRRK2 activation is involved in the development of SAP through proinflammatory cytokine responses upon fungal exposure.

Abstract
Acute pancreatitis (AP) is one of the most common acute abdominal conditions, and its incidence has been increasing for years. Approximately 15-20% of patients develop severe AP (SAP), which is complicated by critical inflammatory injury and intestinal dysfunction. AP-associated inflammation can lead to the gut barrier and function damage, causing dysbacteriosis and facilitating intestinal microbiota migration. Pancreatic exocrine deficiency and decreased levels of antimicrobial peptides in AP can also lead to abnormal growth of intestinal bacteria. Meanwhile, intestinal microbiota migration influences the pancreatic microenvironment and affects the severity of AP, which, in turn, exacerbates the systemic inflammatory response. Thus, the interaction between the gut microbiota (GM) and the inflammatory response may be a key pathogenic feature of SAP. Treating either of these factors or breaking their interaction may offer some benefits for SAP treatment. In this review, we discuss the mechanisms of interaction of the GM and inflammation in AP and factors that can deteriorate or even cure both, including some traditional Chinese medicine treatments, to provide new methods for studying AP pathogenesis and developing therapies.

Abstract
Acute pancreatitis due to antipsychotic treatment is a rare but serious complication. Risperidone is among the rarest atypical antipsychotics associated with acute pancreatitis. Here, we report the case of acute pancreatitis developing 2 years after the use of Risperidone in a young man with schizophrenia. The mechanism and the time of occurrence in this case are at odds with what is generally reported in the literature.

Abstract
BACKGROUND Reactive thrombocytosis occurs secondary to systemic infections, inflammatory, and other conditions. The relationship between thrombocytosis and acute pancreatitis (AP) in inflammatory diseases is uncertain. This study aimed to evaluate the clinical significance of thrombocytosis in AP patients during hospitalization. METHODS Subjects within 48 h of AP onset were consecutively enrolled over 6 years. Platelet counts of ≥ 450,000/µL were defined as thrombocytosis, < 100,000/µL as thrombocytopenia, and other counts as normal. We compared clinical characteristics, including the rate of severe AP (SAP) assessed by the Japanese Severity Score; blood markers, including hematologic and inflammatory factors and pancreatic enzymes during hospitalization; and pancreatic complications and outcomes in the three groups. RESULTS A total of 108 patients were enrolled. Although, SAP was more common in patients with thrombocytosis and thrombocytopenia (87.9% and 100%, respectively), the differences in lymphocytes and C-reactive protein, lactase dehydrogenase, and antithrombin levels, which are factors of the systemic inflammatory response, and the mean platelet volume, an indicator of platelet activation, were observed among patients with thrombocytosis and thrombocytopenia during hospitalization. Regarding pancreatic complications and outcomes, patients with thrombocytosis and thrombocytopenia had higher acute necrotic collection (ANC), pancreatic necrosis, intestinal paralysis, respiratory dysfunction, and pancreatic-related infection levels than patients with normal platelet levels. The relationship between pancreatic complications and thrombocytosis was assessed by multivariate logistic regression; the odds ratios for development of ANC, pancreatic necrosis and pancreatic-related infections were 7.360, 3.735 and 9.815, respectively. CONCLUSIONS Thrombocytosis during hospitalization for AP suggests development of local pancreatic complications and pancreatic-related infections.

Abstract
Antiseizure medications can cause serious adverse reactions and have deleterious drug interactions that often complicate the clinical management of patients. When the US Food and Drug Administration (FDA) wants to alert healthcare providers and patients about the risk of potentially serious or fatal drug reactions, the FDA requires the manufacturers of these medications to format these warnings within a "black-box" border, and prominently display this box on the first section of the package insert; such warnings are called "black-box warnings (BBWs)". The BBW is a way for the FDA to urge physicians to evaluate patients more rigorously and carefully weigh the risks and benefits, before prescribing medication that has the potential to cause serious adverse reactions, and to formulate a plan for close monitoring during therapy. The FDA BBW provides the extra layer of safety but many healthcare providers fail to comply with these warnings. Currently, there are 26 FDA-approved antiseizure medications in the US market, 38% of which have received BBWs, and most of the antiseizure medications with BBWs are older-generation drugs. Some antiseizure medications have multiple BBWs; for example, valproic acid has three BBWs including hepatotoxicity, fetal risk, and pancreatitis, carbamazepine has BBWs of serious skin and hematological reactions, and felbamate also has two BBWs including hepatic failure and aplastic anemia. The purpose of this review is to provide insight into each BBW received by antiseizure medications and discuss the FDA recommendations for evaluating the drug benefit/risk, and for monitoring parameters before the initiation of and during treatment.

Abstract
In recent years, studies have attempted to understand the immune cells and mechanisms underlying the pathogenesis of chronic pancreatitis (CP) by constructing a model of CP. Based on these studies, the innate immune response is a key factor in disease pathogenesis and inflammation severity. Novel mechanisms of crosstalk between immune and non-immune pancreatic cells, such as pancreatic stellate cells (PSC), have also been explored. Immune cells, immune responses, and signaling pathways in CP are important factors in the development and progression of pancreatitis. Based on these mechanisms, targeted therapy may provide a feasible scheme to stop or reverse the progression of the disease in the future and provide a new direction for the treatment of CP. This review summarizes the recent advances in research on immune mechanisms in CP and the new advances in treatment based on these mechanisms.

Abstract
BACKGROUND Visceral adipose tissue (VAT) is related to SAP prognosis. As a depot of VAT, mesenteric adipose tissue (MAT) resides between pancreas and gut, which might affect SAP and the secondary intestinal injury. AIMS To investigate the changes of MAT in SAP. METHODS 24 SD rats were randomly divided into four groups. 18 rats in SAP group were euthanized in time gradients (6 h, 24 h, and 48 h after modeling) and the others in control group. Blood samples and tissues of pancreas, gut, and MAT were taken for analysis. RESULTS Compared to the control group, SAP rats appeared MAT inflammation, presenting higher mRNA expression of TNF-α and IL-6 and lower IL-10, and histological changes after 6 h of modeling, which became worse over time. Flow cytometry showed that B lymphocytes increased in MAT after 24 h of SAP modeling and lasted up to 48 h, earlier than the changes of T lymphocytes and macrophages. The intestinal barrier integrity was damaged after 6 h of modeling, presenting lower mRNA and protein expression of ZO-1 and occludin, higher serum levels of LPS and DAO, with pathological changes, which gradually aggravated after 24 h and 48 h. SAP rats had higher serum levels of inflammatory indicators and revealed histological inflammation of pancreas, the severity of which increased with the passage of modeling time. CONCLUSION MAT appeared inflammation in early-stage SAP, and became worse over time, with the same trend as the intestinal barrier injury and the severity of pancreatitis. B lymphocytes infiltrated early in MAT, which might promote the MAT inflammation.

Abstract
Aims: To demonstrate feasibility and efficacy of simultaneous intraoperative cholangiogram (IOC) and antegrade biliary stenting (ABS) with laparoscopic cholecystectomy (LC) compared with preoperative biliary investigation and delayed LC in acute gallstone pancreatitis (AGP). Methods: A retrospective case-control study was performed comparing patients who had a simultaneous IOC ± ABS with LC at index admission with those who had delayed LC in the treatment of AGP. 74 patients were included in this study from January 2016 to October 2018. All patients who underwent LC for AGP were included in a prospective database with 1 year follow-up. Results: 30 (40.5%) patients underwent simultaneous IOC ± ABS with LC, 11 of these required ABS insertion. 2 (6.7%) patients also underwent magnetic resonance cholangiopancreatography (MRCP). No patients underwent endoscopic retrograde cholangiopancreatography (ERCP). No patients were readmitted with AGP or symptomatic gallbladder. Mean length of total hospital admission was 10.1 days. 44 (59.5%) patients underwent delayed LC. Of this cohort, 7 (15.9%) patients underwent ERCP and 19 (43.2%) underwent MRCP. In total, there were 19 (43.2%) readmissions in this group with pancreatitis or symptomatic gallbladder. Mean length of total hospital admission was 13 days. Conclusions: In our pilot study we demonstrated that performing simultaneous IOC ± ABS with LC is a feasible option in the secondary care setting. Using this surgical technique, we have demonstrated a reduction in readmissions with AGP and symptomatic gallbladder while also reducing the number of CBD investigations required. Using simultaneous IOC ± ABS with LC reduced the mean total length of stay in hospital.

Abstract
BACKGROUND Current guidelines recommend cholecystectomy during the index admission for gallstone pancreatitis, and a growing body of evidence indicates that patients benefit from cholecystectomy within the first 48 h of admission. We examined the impact of hospital characteristics on adherence to these data-driven practices. METHODS We queried the National Inpatient Sample for patients admitted for gallstone pancreatitis between October 2015 and December 2018. Patients who underwent same-admission cholecystectomy were identified by procedure codes. Cholecystectomies within the first two days were classified as early cholecystectomies. Multivariable logistic regression was used to determine the association between hospital characteristics and adherence to these practices. RESULTS Of 163,390 admissions for gallstone pancreatitis, only 90,790 (55.6%) underwent cholecystectomy before discharge. Mean time from admission to cholecystectomy was 2.9 days; 27.0% of patients (44,005) underwent early cholecystectomy. Odds of same-admission cholecystectomy were highest in large hospitals (OR 1.21, 95% CI 1.13-1.28), urban teaching centers (OR 1.33, 95% CI 1.21-1.46), and the South (OR 1.70, 95% CI 1.57-1.83). Odds of early cholecystectomy did not vary with hospital size, urban-rural status, or teaching status but were highest in the West (OR 1.98, 95% CI 1.80-2.18). CONCLUSION Best-practice adherence for cholecystectomy in gallstone pancreatitis remains low despite an abundance of evidence and clinical practice guidelines. Active interventions are needed to improve delivery of surgical care for this patient population. Implementation efforts should focus on small hospitals, rural areas, and health systems in the Northeast region.

Abstract
Hypercalcaemia-induced pancreatitis is a rare and often overlooked phenomena. Despite hyperparathyroidism being a common cause of hypercalcaemia, the association between pancreatitis and hyperparathyroidism remains controversial and is often overlooked. Patients may however suffer serious complications when diagnosis and treatment of hyperparathyroidism are delayed due to insufficient awareness. We present a man in his 40s who was admitted with progressive epigastric pain due to pancreatitis. Blood tests showed elevated serum calcium levels, which led to extensive investigation. Further workups led to the diagnosis of primary hyperparathyroidism due to three parathyroid adenomas. The patient underwent minimally invasive parathyroidectomy, which was followed by an uncomplicated recovery and normal serum calcium levels.

Abstract
Acute pancreatitis is a common emergent disorder, a significant population of which develops the life-threatening condition, called severe acute pancreatitis (SAP). It is generally accepted that bacterial infection is associated with the development and persistence of SAP. In addition to bacterial infection, recent clinical studies disclosed a high incidence of fungal infection in patients with SAP. Moreover, SAP patients with fungal infection exhibit a higher mortality rate than those without infection. Although these clinical studies support pathogenic roles played by fungal infection in SAP, beneficial effects of prophylactic anti-fungal therapy on SAP have not been proved. Here we summarize recent clinical findings as to the relationship between fungal infection and the development of SAP. In addition, we discuss molecular mechanisms accounting for the development of SAP in the presence of fungal infection.

Abstract
Background: Immediate or delayed catheter drainage of infected pancreatic necrosis remains a subject of debate. The present study aimed to evaluate the optimum timing for drainage in patients with infected necrotizing pancreatitis. Methods: A prospective, observational study was undertaken at the Department of Surgery, Liaquat University of Medical & Health Sciences (LUMHS), between 1st March 2018 and 6th July 2020. All patients 18 years or older presenting with acute pancreatitis (AP) in whom necrotizing pancreatitis was confirmed or suspected were enrolled in the study. The exclusion criteria included prior intervention for necrotizing pancreatitis. Those who were diagnosed with infected necrotizing pancreatitis were labeled as Group A and Group B. Group A patients underwent immediate catheter drainage (within 24 h of admission) while Group B patients underwent delayed drainage (after 24 h). Clinical outcome variables including complication rate, mortality, length of hospital, and intensive care unit (ICU) stay were collected in a predefined pro forma. Results: One hundred and thirty patients were enrolled in the study. There were 65 patients in each group. The present study revealed no significant differences in patient outcomes in the immediate drainage group vs. the postponed drainage group. Overall, the mortality rate was 15.38% in Group A while the mortality rate was a little lower in Group B, i.e. 10.77% (p=0.44). The acute onset multiple organ failure was lower in Group A as compared to Group B, however, the difference was statistically insignificant (p=0.08). The rate of wound infection rate was 10.77% and 15.38% in Group A and Group B, respectively (p=0.61). Conclusion: In the present study, we failed to find any significant difference between the immediate and postponed drainage group in terms of patient outcome. As per current findings, the timing of drainage did not impact the prognosis of patients with necrotizing pancreatitis.

Abstract
Impaired intestinal barrier function and gut microbiota dysbiosis are believed to be related to exacerbation of acute pancreatitis (AP). As a bacterial cell wall peptidoglycan component, diaminopimelic acid (DAP) is a specific ligand of NOD1 that regulates the NOD1/RIP2/NF-kB signaling pathway. Here, we investigated the role of DAP in the crosstalk between the gut microbiota and pancreas during the occurrence of AP. Upregulation of NOD1/RIP2/NF-kB and elevated serum DAP levels were found in severe AP (SAP) model rats. The accumulation of DAP in SAP patients corroborated its ability to serve as an indicator of disease severity. Subsequently, SAP rats were treated with oral administration of the traditional Chinese medicine Qingyi Keli (QYKL) as well as neomycin, which can widely eliminate DAP-containing bacteria. Both QYKL and neomycin intervention ameliorated intestinal and pancreatic damage and systemic inflammation in SAP rats. Through 16S rDNA sequencing, we found that QYKL could rehabilitate the gut microbiota structure and selectively inhibit the overgrowth of enteric bacteria, such as Helicobacter and Lactobacillus, in SAP rats without affecting some protective strains, including Romboutsia and Allobaculum. Interestingly, we demonstrated that the decrease in serum DAP was accompanied by suppression of the NOD1/RIP2/NF-kB signaling pathway in both the intestine and pancreas of the two intervention groups. Taken together, these results suggested that the gut microbiota-DAP-NOD1/RIP2 signaling pathway might play a critical role in the progression of AP and that SAP could be alleviated via intervention in the signaling pathway. Our work provides new potential early warning indicators of SAP and targets for intervention.

Abstract
BACKGROUND The majority of cases of idiopathic acute pancreatitis (IAP) are thought to result from occult biliary disease. A growing body of evidence suggests that cholecystectomy for IAP reduces the risk of recurrence by up to two thirds. This study examined nationwide uptake and disparities in adoption of cholecystectomy for IAP. METHODS The National Inpatient Sample was queried to identify admissions for IAP between October 2015 and December 2018. Patients who underwent cholecystectomy before discharge and those that did not were compared using Wald χ2 tests for categorical variables and Student's t test for continuous variables. Patient- and hospital-level predictors of cholecystectomy were identified using weighted multivariable logistic regression. RESULTS Of 62,305 estimated admissions for IAP, only 665 (1.1%) underwent cholecystectomy before discharge. Female sex, initiation of total parenteral nutrition (TPN), insurance status, and hospital type were associated with cholecystectomy on univariable analysis. On multivariable analysis, Hispanic patients (odds ration [OR] 1.60, 95% confidence interval [CI] 1.01-2.56), patients on TPN (OR 2.70, 95% CI 1.17-6.24), and those with private insurance (OR 2.18, 95% CI 1.48-3.21 versus Medicare/Medicaid) were more likely to receive operations. Small hospitals and hospitals in rural areas were least likely to perform empiric cholecystectomies. CONCLUSION Despite increasing evidence supporting cholecystectomy after IAP, the practice remains rare in the United States. Educational efforts and active implementation efforts are needed to promote adoption. Particular attention should be focused on small, rural centers and those that disproportionately care for uninsured patients and patients with public insurance.

Abstract
OBJECTIVES Basic science studies suggest that opioids aggravate disease severity and outcomes in acute pancreatitis. We sought to determine the association of opioid use and opioid type with the clinical course and outcome of acute pancreatitis. METHODS In this retrospective single-center observational study, we included all adult patients admitted with acute pancreatitis between 2008 and 2021. Patients were classified into 3 groups based on analgesia type: morphine, noonmorphine opioid, and nonopioid. RESULTS We included 2308 patients. Of the patients, 343 (14.9%) were treated with morphine, 733 (31.8%) were treated with nonmorphine opioids, and 1232 (53.4%) patients were in the nonopioid group. The incidence of 30-day mortality did not differ significantly between study groups: 3.9%, 2.9%, and 4.4% in the nonopioid, nonmorphine-opioid, and morphine groups, respectively ( P = 0.366).In multivariate analysis, the composite end point consisting of 30-day mortality, invasive ventilation, emergent abdominal surgery, and need for vasopressors was significantly more likely to occur in the morphine group than in the nonopioid group (adjusted odds ratio, 1.69; 95% confidence interval, 1.1-2.598; P = 0.01). CONCLUSIONS Mortality among acute pancreatitis patients did not differ significantly between patients receiving morphine, nonmorphine opioids, and nonopioids. However, morphine treatment was associated with higher rates of some serious adverse events.

A novel resveratrol analog upregulates sirtuin 1 and inhibits inflammatory cell infiltration in acute pancreatitis. Acta Pharmacol Sin 2022; 43:1264-1273. [PMID: 34363008 PMCID: PMC9061839 DOI: 10.1038/s41401-021-00744-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2021] [Accepted: 07/12/2021] [Indexed: 01/05/2023] Open
Abstract
Acute pancreatitis (AP), an inflammatory disorder of the pancreas, is a complicated disease without specific drug therapy. (R)-4,6-dimethoxy-3-(4-methoxy phenyl)-2,3-dihydro-1H-indanone [(R)-TML104] is a synthesized analog of the natural product resveratrol sesquiterpenes (±) -isopaucifloral F. This study aimed to investigate the effect and underlying mechanism of (R)-TML104 on AP. The experimental AP model was induced by caerulein hyperstimulation in BALB/c mice. (R)-TML104 markedly attenuated caerulein-induced AP, as evidenced by decreased pancreatic edema, serum amylase levels, serum lipase levels, and pancreatic myeloperoxidase activity. In addition, (R)-TML104 significantly inhibited the expression of pancreatic chemokines C-C motif chemokine ligand 2 and macrophage inflammatory protein-2 and the infiltration of neutrophils and macrophages. Mechanistically, (R)-TML104 activated AMP-activated protein kinase and induced sirtuin 1 (SIRT1) expression. (R)-TML104 treatment markedly induced the SIRT1-signal transducer and activator of transcription 3 (STAT3) interaction and reduced acetylation of STAT3, thus inhibiting the inflammatory response mediated by the interleukin 6-STAT3 pathway. The effect of (R)-TML104 on SIRT1-STAT3 interaction was reversed by treatment with a SIRT1 inhibitor selisistat (EX527). Together, our findings indicate that (R)-TML104 alleviates experimental pancreatitis by reducing the infiltration of inflammatory cells through modulating SIRT1.

Abstract
Pancreatitis occurs in two forms defined by its chronicity. Acute pancreatitis (AP) occurs suddenly and only lasts for several days. Consequently, most patients with AP recover without permanent damage to the pancreas, and about 20% of patients with AP have severe disease. In contrast, chronic pancreatitis (CP) is a long-lasting inflammation that causes permanent damage to pancreatic tissue; consequently, this form is marked by the emergence of persistent endocrine and exocrine pancreatic insufficiency. Despite these differences, AP and CP share central mechanisms of disease: in both forms, inflammation is initiated and/or sustained by the intrapancreatic activation of pancreatic digestive enzymes followed by the autodigestion of pancreatic tissues. In addition, in both forms enzymatic damage is accompanied by changes in intestinal permeability and entry of commensal organisms into the pancreas where they elicit innate immune responses that ultimately dominate and define pancreatic inflammation. In the murine models of AP and CP described here, both of these elements of pancreatitis pathogenesis are taken into account. Thus, in one approach mice are administered high doses of cerulein, a cholecystokinin analog with the ability at this dose to induce excessive activation of the cholecystokinin receptor expressed in pancreatic acinar cells and the release of active trypsin that causes both direct and indirect acinar damages due to entry of commensal organisms and stimulation of innate immune responses. In a second approach mice are administered low doses of cerulein, which causes little or no damage to the pancreas unless given along with nucleotide-binding oligomerization domain 1 (NOD1) ligand, which in the presence of low-dose cerulein administration induces a pathologic innate immune response mediated by NOD1. These approaches are adopted to produce AP when cerulein or cerulein plus NOD1 ligand is applied only once or to produce CP when a similar regimen is applied multiple times. © 2022 Wiley Periodicals LLC.

Abstract
Asparaginase, a critical component of current pediatric acute leukemia treatment protocols, is associated with a number of serious side effects, one of which is pancreatitis. Pancreatitis can result in significant morbidity and mortality from necrosis, pseudocyst formation, hemorrhage, systemic inflammation, intestinal perforation, and sepsis. Another rare complication of pancreatitis is posterior reversible encephalopathy syndrome, likely mediated by systemic inflammation secondary to pancreatic autodigestion and proinflammatory cytokine-mediated vascular endothelial damage. Here, we review this association in the literature and report 2 pediatric patients with leukemia who developed posterior reversible encephalopathy syndrome in the setting of asparaginase-associated pancreatitis.

Abstract
PURPOSE The purpose of this study was to identify attenuation threshold value on computed tomography (CT) that allowed discriminating between interstitial edematous pancreatitis (IEP) and necrotizing pancreatitis (NP) in patients with acute pancreatitis during the first week of the disease and evaluate interobserver reproducibility for the diagnosis of acute pancreatitis category. MATERIALS AND METHODS Patients with acute pancreatitis who underwent CT examination of the abdomen between March 2015 and December 2019 were retrospectively included. Actual diagnosis of IEP or NP was based on final clinical report, follow-up evaluation, and complications. Six regions of interest were manually placed in the pancreatic gland and peripancreatic fat, and differences in CT attenuation values before contrast injection and during the portal venous phase of enhancement were computed. Performance in the diagnosis of AP category was evaluated using receiver operating characteristic analysis. Interobserver agreement was estimated by the intraclass correlation coefficient (ICC) and Bland Altman analysis was used to estimate reproducibility between pairs of observers. RESULTS Sixty-six patients with NP (46 men, 20 women; mean age, 55 ± 17 [SD] years; age range: 20-89 years) and 70 patients with IEP (39 men, 31 women; mean age, 54 ± 18 [SD] years; age range: 21-87 years) were included. An enhancement value less than 30 Hounsfield units (HU) in the pancreatic gland during the portal phase compared to non-contrast phase, yielded 90.9% sensitivity (60/66; 95% CI: 81.3-96.6), 94.3% specificity (66/70; 95% CI: 86.0-98.4) and an area under curve of 0.958 (95% CI: 0.919-0.996) for the diagnosis of NP versus IEP. Interobserver reproducibility for pancreas enhancement was good using Bland Altman plot and ICC was excellent for pancreatic gland analysis (ICC 0.978; 95% CI: 0.961-0.988) but poor or moderate (ICC ≤0.634) regarding peripancreatic fat necrosis. CONCLUSION By using a pancreas enhancement threshold value of 30 HU, CT is accurate and reproducible for the diagnosis of NP during the first week of the disease.

Abstract
Pancreatitis is a fatal disease associated with significant mortality and morbidity. At present, no specific treatment is available for pancreatitis and the patients are mainly treated with supportive medication. The need for specific antipancreatitic chemotherapy is an urgent medical obligation. In the current study, protective effects of the methanolic extract of the Ligustrum vulgare berries were investigated in the rat model of acute pancreatitis. Acute pancreatitis (AP) was induced in the male Sprague-Dawley (SD) rats by cerulein injection. Fruit extract of L. vulgare L extract was prepared using the methanol. Treatment effects of L. vulgare were evaluated in AP rats. Serum levels of lipase, amylase, proinflamatory cytokines (TNF-α, IL-6, TL-1β), lipid peroxidase (LPO), myeloperoxidase (MPO) were determined. Histological changes in the pancreas were assessed. L. vulgare treatment prevented the increase in serum amylase and lipase levels, reduced the disease progression in pancreas, and reduced the serum levels of tumour necrosis factor (TNF)-α, interleukin (IL)-6, and IL-1β in AP rats. Moreover, L. vulgare significantly suppressed pancreatic edema, inhibited oxidative damage (MPO activity and SOD activity), and inhibited the expression of NF-κB/p65 and activation (phosphorylation) of the inhibitor of NF-κB (IκBα) and p38 MAPKs. Histological examinations showed that L. vulgare significantly reduced the inflammatory and fibrotic changes. The results indicated the potent pancreato-protective effects of L. vulgare in AP.

Activation of TLR4 induces severe acute pancreatitis-associated spleen injury via ROS-disrupted mitophagy pathway. Mol Immunol 2021; 142:63-75.

Abstract
Severe acute pancreatitis (SAP) is complicated by systemic inflammatory response syndrome and multiple organ dysfunction, the disease will eventually result in death in almost half of the case. The spleen, as the largest immune organ adjacent to the pancreas, is prone to damage in SAP, thereby aggravating the damage of other organs and increasing mortality. However, to date, the research on the mechanism and treatment of spleen injury caused by SAP is still in its infancy. Herein, we investigated the mechanism of spleen injury, and explored the application potential of tuftsin for relieving spleen damage in SAP mice. Firstly, SAP mice model was constructed via the retrograde infusion of 3.5 % sodium taurocholate into the biliopancreatic duct. Then, we proved that the up-regulation of Toll-like receptor 4 (TLR4) in spleen would lead to the accumulation of reactive oxygen species (ROS) and mitochondrial dysfunction under SAP conditions. The splenic ROS and mitochondrial dysfunction could be improved by N-acetylcysteine (NAC) treatment or knocking out TLR4 in SAP mice. Meanwhile, we found that NAC treatment could also improve the autophagy of spleen tissue, suggesting that splenic ROS may affect impaired autophagy, causing the accumulation of damaged mitochondria, aggravating spleen damage. Furthermore, we verified the mechanism of spleen injury is caused by splenic ROS affecting PI3K/p-AKT/mTOR pathway-mediated autophagy. In addition, we detected the spleen injury caused by SAP could decrease the concentration of tuftsin in the serum of mice. Whereas, exogenous supplementation of tuftsin ameliorated the pathological damage, ROS accumulation, impaired autophagy, inflammation expression and apoptosis in damaged spleen. In summary, we verified the new mechanism of SAP-caused spleen damage that TLR4-induced ROS provoked mitophagy impairment and mitochondrial dysfunction in spleen via PI3K/p-AKT mTOR signaling, and the application potential of tuftsin in treating spleen injury, which might expand novel ideas and methods for the treatment of pancreatitis.

Abstract
Pancreatitis is known to be painful in humans and companion animals. However, the extent of pain in experimental mouse models of acute pancreatitis is unknown. Consequently, the severity classification of acute pancreatitis in mice is controversially discussed and standardized pain management is missing. In this study, we investigated acute Cerulein-induced pancreatitis with pain-specific and well-being orientated parameters to detect its impact on mice. Male C57BL/6J male mice were injected with Cerulein; animals that received saline injections served as control group. The animals were observed for weight change and water intake. To assess pain, behaviors like stretch-and-press and reduced rearing, the Mouse Grimace Scale, and von Frey hypersensitivity were assessed. Fecal corticosterone metabolites and burrowing behavior were assessed to detect changes in the animal’s well-being. Pancreatitis severity was evaluated with amylase and lipase in the blood and pancreas histology. To investigate whether different analgesics can alleviate signs of pain, and if they influence pancreas inflammation, animals received Buprenorphine, Paracetamol in combination with Tramadol, or Metamizole in the drinking water. The calculated intake of these analgesics via drinking reached values stated to be efficient for pain alleviation. While pancreatitis did not seem to be painful, we detected acute pain from Cerulein injections that could not be alleviated by analgesics. The number of inflammatory cells in the pancreas did not differ with the analgesic administered. In conclusion: (1) Cerulein injections appear to be acutely painful but pain could not be alleviated by the tested analgesics, (2) acute pancreatitis induced by our protocol did not induce obvious signs of pain, (3) analgesic substances had no detectable influence on inflammation. Nevertheless, protocols inducing more severe or even chronic pancreatitis might evoke more pain and analgesic treatment might become imperative. Considering our results, we recommend the use of Buprenorphine via drinking water in these protocols. Further studies to search for efficient analgesics that can alleviate the acute pain induced by Cerulein injections are needed.

Abstract
Purpose Acute pancreatitis (AP) is an inflammatory disease. AP starts with sterile inflammation and is often complicated with critical local or systemic infection or sepsis in severe cases. Septic AP activates peptidyl arginine deiminase (PAD) and citrullinates histone H3 (CitH3), leading to neutrophil extracellular trap (NET) formation. Investigating the role of NETs and underlying mechanisms in septic AP may facilitate developing diagnostic and therapeutic approaches. In this study, we sought to identify the expression of CitH3 in septic AP patients and to analyze the correlation of CitH3 concentration with NET components as well as clinical outcomes. Methods Seventy AP patients with or without sepsis (40 septic cases, 30 nonseptic cases) and 30 healthy volunteers were recruited in this study. Concentration of NET components (CitH3 and double-strain DNA) and key enzymes (PAD2/4) were measured. Clinical and laboratory characteristics of patients were recorded and analyzed. Results Levels of CitH3 were elevated significantly in septic AP patients compared with those in nonseptic AP and healthy volunteers. The area under the curve (AUC, 95% confidence interval) for diagnosing septic AP was 0.93 (0.86–1.003), and the cutoff was 43.05 pg/ml. Among septic AP cases (n = 40), the concentration of CitH3 was significantly increased in those who did not survive or were admitted to the intensive care unit, when compared with that in those who survived or did not require intensive care unit. Association analysis revealed that CitH3 concentration was positively correlated with PAD2, PAD4, dsDNA concentration, and Sequential Organ Failure Assessment scores. Conclusion CitH3 concentration increased in septic AP patients and was closely correlated with disease severity and clinical outcomes. CitH3 may potentially be a diagnostic and prognostic biomarker of septic AP.

Abstract
INTRODUCTION Acute Pancreatitis is a common disease, diagnosed in about 3% of cases presenting with abdominal pain. Severe disease with multiple systemic complications develops in 10-20% of the cases which require intensive care in specialized centres. Harmless acute pancreatitis score is a simple and economical score predicting the non-severe course of disease within 30 minutes of admission. The aim of our study was to find the prevalence of harmless (harmless acute pancreatitis) among cases of acute pancreatitis in a tertiary care centre. METHODS A descriptive cross-sectional study was conducted after obtaining the ethical approval (Reference no. 344/2076/77). The study was carried out from September 2019 to February 2020 taking 50 patients with the first attack of acute pancreatitis. Convenient sampling was done. Harmless acute pancreatitis score prediction of severe disease and final outcome as severe or non-severe was noted with predefined severity criteria. Data were entered in Microsoft Excel and Statistical Package for the Social Sciences and results represented in tables and charts. Point estimate at 95% was done and frequency and percentage were calculated. RESULTS Out of 50 patients with first attack of acute pancreatitis, using the harmless acute pancreatitis score, the prevalence of harmless acute pancreatitis was 22 (56%) (44.45-67.5 at 90% Confidence Interval). CONCLUSIONS The harmless acute pancreatitis score is an easy, less expensive, quick and promising early scoring system for prediction of non-severe courses of acute pancreatitis. The prevalence of harmless (harmless acute pancreatitis) among cases of acute pancreatitis was found to be similar to other studies.

Abstract
Acute lung injury (ALI), or its more severe form, acute respiratory distress syndrome (ARDS), is a disease with high mortality and is a serious challenge facing the World Health Organization because there is no specific treatment. The excessive and prolonged immune response is the hallmark of this disorder, so modulating and regulating inflammation plays an important role in its prevention and treatment. Resolvin D1 (RvD1) as a specialized pro-resolving mediator has the potential to suppress the expression of inflammatory cytokines and to facilitate the production of antioxidant proteins by stimulating lipoxin A4 receptor/formyl peptide receptor 2 (ALX/FPR2). These changes limit the invasion of immune cells into the lung tissue, inhibit coagulation, and enhance cell protection against oxidative stress (OS). In particular, this biomolecule reduces the generation of reactive oxygen species (ROS) by blocking the activation of inflammatory transcription factors, especially nuclear factor-κB (NF-κB), and accelerating the synthesis of antioxidant compounds such as heme oxygenase 1 (HO-1) and superoxide dismutase (SOD). Therefore, the destruction and dysfunction of important cell components such as cytoplasmic membrane, mitochondria, Na+/k + adenosine triphosphatase (ATPase) and proteins involved in the phagocytic activity of scavenger macrophages are attenuated. Numerous studies on the effect of RvD1 over inflammation using animal models revealed that Rvs have both anti-inflammatory and pro-resolving capabilities and therefore, might have potential therapeutic value in treating ALI. Here, we review the current knowledge on the classification, biosynthesis, receptors, mechanisms of action, and role of Rvs in ALI/ARDS.

Abstract
Acute pancreatitis (AP) is an inflammatory disease of the pancreas. The severity is classified as mild (MAP), moderately severe (MSAP), or severe (SAP). In patients with SAP, organ dysfunction can occur in the early stage of the disease course, accompanied by secondary infection, with a mortality rate of 36%-50%. In the late stage SAP, infection-related complications caused by pancreatic necrotic tissue and peripancreatic effusion are the main causes of death in patients. Dysbacteriosis of intestinal microflora, barrier dysfunction of intestinal mucosa, and translocation of enteric bacteria are considered to be the main causes of infection of pancreatic necrotic tissue and peripancreatic effusion. During the past few years, increasing attention has been paid to the metabolic activities of intestinal microflora in SAP, which plays an important role in the metabolic activities of the human body. This review is aimed at bringing together the most recent findings and advances regarding the gut microbial community and associated gut microbial community metabolites and illustrating the role of these metabolites in disease progression in severe acute pancreatitis. We hope that this review will provide new ideas and schemes for the treatment of SAP in the clinical settings.

Abstract
Background Assessment of the biliary origin of acute pancreatitis (AP) is crucial because it affects patient treatment to avoid recurrence. Although CT is systematically performed to determine severity in AP, its usefulness in assessing AP biliary origin has not been evaluated. Purpose To assess abdominal CT features associated with acute biliary pancreatitis (ABP) and to evaluate the predictive value of a combination of CT and clinical data for determining a biliary origin in a first episode of AP. Materials and Methods From December 2014 to May 2019, all consecutive patients who presented with a first episode of AP and with at least 6 months of follow-up were retrospectively reviewed. Evidence of gallstones was mandatory for a clinical diagnosis of ABP. Abdominal CT images were reviewed by two abdominal radiologists. Univariable and multivariable statistical analyses were performed, and a nomogram was constructed on the basis of the combination of clinical and CT features. This nomogram was validated in a further independent internal cohort of patients. Results A total of 271 patients (mean age ± standard deviation, 56 years ± 20; 160 men) were evaluated. Of these, 170 (63%) had ABP. At multivariable analysis, age (odds ratio [OR], 1.06; 95% CI: 1.03, 1.09; P < .001), alanine aminotransferase level (OR, 1.00; 95% CI: 1.00, 1.01; P = .009), gallbladder gallstone (OR, 15.59; 95% CI: 4.61, 68.62; P < .001), choledochal ring sign (OR, 5.73; 95% CI: 2.11, 17.05; P < .001), liver spontaneous attenuation (OR, 1.07; 95% CI: 1.04, 1.11; P < .001), and duodenal thickening (OR, 0.17; 95% CI: 0.03, 0.61; P = .01) were independently associated with ABP. The matching nomogram combining both clinical and CT features displayed an area under the curve of 0.94 (95% CI: 0.91, 0.97) in the study sample (n = 271) and 0.91 (95% CI: 0.84, 0.99) in the validation cohort (n = 51). Conclusion Abdominal CT provided useful features for diagnosis of acute biliary pancreatitis (ABP). Combining CT and clinical features in a nomogram showed good diagnostic performance for early diagnosis of ABP. © RSNA, 2021 Online supplemental material is available for this article.

Inflammatory capacity of exosomes released in the early stages of acute pancreatitis predicts the severity of the disease. J Pathol 2021; 256:83-92.

Abstract
As acute pancreatitis progresses to the severe form, a life-threatening systemic inflammation is triggered. Although the mechanisms involved in this process are not yet well understood, it has been proposed that circulating exosomes may be involved in the progression of inflammation from the pancreas to distant organs. Here, the inflammatory capacity and protein profile of plasma exosomes obtained during the first 24 h of hospitalization of patients diagnosed with acute pancreatitis were characterized and compared with the final severity of the disease. We found that the final severity of the disease strongly correlates with the inflammatory capacity of exosomes in the early stages of acute pancreatitis. Exosomes isolated from patients with mild pancreatitis had no effect on macrophages, while exosomes isolated from patients with severe pancreatitis triggered NFκB activation, TNFα and IL1β expression, and free radical generation. To delve deeper into the mechanism involved, we performed a proteomic analysis of the different exosomes that allowed us to identify different groups of proteins whose concentration was also correlated with the clinical classification of pancreatitis. In particular, an increase in the amount of S100A8 and S100A9 carried by exosomes of severe pancreatitis suggests that the mechanism of action of exosomes is mediated by the effect of these proteins on NADPH oxidase. This enzyme is activated by S100A8/S100A9, thus generating free radicals and promoting an inflammatory response. Along these lines, we observed that inhibition of this enzyme abolished all the pro-inflammatory effects of exosomes from severe pancreatitis. All this suggests that the systemic effects, and therefore the final severity of acute pancreatitis, are determined by the content of circulating exosomes generated in the early hours of the process. © 2021 The Authors.

Abstract
Management of early nutrition plays an important role in the treatment of acute pancreatitis patients, but the sample sizes of randomized control trials that have compared enteral and parental nutrition were small. From the data of Diagnostic Procedure Combination, we identified patients who had been diagnosed with acute pancreatitis and discharged from the hospital between 2014 and 2015. We compared the length of hospital stay and hospital mortality among patients with acute pancreatitis that was managed with and without enteral nutrition within 7 days from hospitalization. The results showed a significant decrease in the in-hospital mortality rate of 56% (odds ratio 0.444, 95% confidence interval [CI] 0.358 - 0.551, P < 0.001) and length of hospital stay by 8.6 days (95% CI -9.05 - -8.13, P < 0.001) when enteral nutrition was administered within 7 days. According to multivariate analysis, early enteral nutrition was independently associated with in-hospital mortality rate and length of hospitalization. Enteral nutrition is an important management method for the treatment of acute pancreatitis patients.

Abstract
The gut microbiome is a complex microbial community, recognized for its potential role in physiology, health, and disease. The available evidence supports the role of gut dysbiosis in pancreatic disorders, including acute pancreatitis (AP). In AP, the presence of gut barrier damage resulting in increased mucosal permeability may lead to translocation of intestinal bacteria, necrosis of pancreatic and peripancreatic tissue, and infection, often accompanied by multiple organ dysfunction syndrome. Preserving gut microbial homeostasis may reduce the systemic effects of AP. A growing body of evidence suggests the possible involvement of the gut microbiome in various pancreatic diseases, including AP. This review discusses the possible role of the gut microbiome in AP. It highlights AP treatment and supplementation with prebiotics, synbiotics, and probiotics to maintain gastrointestinal microbial balance and effectively reduce hospitalization, morbidity and mortality in an early phase. It also addresses novel therapeutic areas in the gut microbiome, personalized treatment, and provides a roadmap of human microbial contributions to AP that have potential clinical benefit.

Abstract
Pancreatic diseases such as pancreatitis, type 1 diabetes and pancreatic cancer impose substantial health-care costs and contribute to marked morbidity and mortality. Recent studies have suggested a link between gut microbiota dysbiosis and pancreatic diseases; however, the potential roles and mechanisms of action of gut microbiota in pancreatic diseases remain to be fully elucidated. In this review, we summarize the evidence that supports relationship between alterations of gut microbiota and development of pancreatic diseases, and discuss the potential molecular mechanisms of gut microbiota dysbiosis in the pathogenesis of pancreatic diseases. We also propose current strategies toward gut microbiota to advance a developing research field that has clinical potential to reduce the cost of pancreatic diseases.

Abstract
Severe acute pancreatitis (SAP) is a severe acute abdominal disease. Recent evidence shows that intestinal homeostasis is essential for the management of acute pancreatitis. Chitosan oligosaccharides (COS) possess antioxidant activity that are effective in treating various inflammatory diseases. In this study we explored the potential therapeutic effects of COS on SAP and underlying mechanisms. Mice were treated with COS (200 mg·kg-1·d-1, po) for 4 weeks, then SAP was induced in the mice by intraperitoneal injection of caerulein. We found that COS administration significantly alleviated the severity of SAP: the serum amylase and lipase levels as well as pancreatic myeloperoxidase activity were significantly reduced. COS administration suppressed the production of proinflammatory cytokines (TNF-α, IL-1β, CXCL2 and MCP1) in the pancreas and ileums. Moreover, COS administration decreased pancreatic inflammatory infiltration and oxidative stress in SAP mice, accompanied by activated Nrf2/HO-1 and inhibited TLR4/NF-κB and MAPK pathways. We further demonstrated that COS administration restored SAP-associated ileal damage and barrier dysfunction. In addition, gut microbiome analyses revealed that the beneficial effect of COS administration was associated with its ability to improve the pancreatitis-associated gut microbiota dysbiosis; in particular, probiotics Akkermansia were markedly increased, while pathogenic bacteria Escherichia-Shigella and Enterococcus were almost eliminated. The study demonstrates that COS administration remarkably attenuates SAP by reducing oxidative stress and restoring intestinal homeostasis, suggesting that COS might be a promising prebiotic agent for the treatment of SAP.

Abstract
A wild adult male giant panda that was rescued from a nature reserve in Sichuan Province, China, has died. The panda had been in poor physical condition: it was wheezing and had increased serum amylase. A pathological examination was performed in order to determine the cause of death. Gross examination revealed 1380 mL of yellowish fluid in the abdominal cavity, 356 nematodes in the digestive tract and one filling the pancreatic duct, contractions and variably-sized dark purple areas in the spleen, a collapsed right lung and consolidation of the left lung. Acute pancreatitis was confirmed histopathologically via edema, focal necrosis and hemorrhage with inflammatory cell infiltration. Other major histopathological changes included serous-hemorrhagic pneumonia, lymphocytic necrosis and depletion in the spleen, and degeneration and necrosis of renal tubular epithelial cells. The nematodes were identified as Baylisascaris schroederi via molecular assays. In conclusion, the cause of death of the giant panda was determined to be multiple organ dysfunction syndrome caused by baylisascariasis-induced acute pancreatitis. To our knowledge, this is the first report of fatal baylisascariasis-induced acute pancreatitis in the giant panda.

Wu Q, Wang J, Qin M, Yang H, Liang Z, Tang G. Accuracy of conventional and novel scoring systems in predicting severity and outcomes of acute pancreatitis: a retrospective study. Lipids Health Dis 2021; 20:41. [PMID: 33906658 PMCID: PMC8080352 DOI: 10.1186/s12944-021-01470-4] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2021] [Accepted: 04/20/2021] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Recently, several novel scoring systems have been developed to evaluate the severity and outcomes of acute pancreatitis. This study aimed to compare the effectiveness of novel and conventional scoring systems in predicting the severity and outcomes of acute pancreatitis. METHODS Patients treated between January 2003 and August 2020 were reviewed. The Ranson score (RS), Glasgow score (GS), bedside index of severity in acute pancreatitis (BISAP), pancreatic activity scoring system (PASS), and Chinese simple scoring system (CSSS) were determined within 48 h after admission. Multivariate logistic regression was used for severity, mortality, and organ failure prediction. Optimum cutoffs were identified using receiver operating characteristic curve analysis. RESULTS A total of 1848 patients were included. The areas under the curve (AUCs) of RS, GS, BISAP, PASS, and CSSS for severity prediction were 0.861, 0.865, 0.829, 0.778, and 0.816, respectively. The corresponding AUCs for mortality prediction were 0.693, 0.736, 0.789, 0.858, and 0.759. The corresponding AUCs for acute respiratory distress syndrome prediction were 0.745, 0.784, 0.834, 0.936, and 0.820. Finally, the corresponding AUCs for acute renal failure prediction were 0.707, 0.734, 0.781, 0.868, and 0.816. CONCLUSIONS RS and GS predicted severity better than they predicted mortality and organ failure, while PASS predicted mortality and organ failure better. BISAP and CSSS performed equally well in severity and outcome predictions.

[PMID: 33866269 DOI: 10.1016/j.ajem.2021.04.026] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2021] [Revised: 03/31/2021] [Accepted: 04/10/2021] [Indexed: 12/12/2022] Open
Abstract
INTRODUCTION Computed tomography (CT) is often ordered for patients in whom the diagnosis of acute pancreatitis (AP) has already been established via elevated lipase levels and typical abdominal pain. We investigated whether early CT imaging performed in the ED altered the diagnosis or management. METHODS A retrospective chart review was performed on patients presenting to a large, academic ED between the years 2013-2015 with AP who received CT imaging. Relevant history, laboratory, imaging data, and hospital course were abstracted from the medical record and analyzed by three independent reviewers, with 100% agreement among reviewers on 30 randomly selected cases. The primary outcome was whether the CT led to a change in diagnosis or management above and beyond the ultrasound. Univariate and multivariate analyses were performed to determine association between predictor variables and outcomes. RESULTS The electronic health record query yielded 458 patients. Of those, 174 met the American College of Gastroenterology criteria for AP and were included in the study. 145 patients (83%) had abdominal CT during their hospital course, 125 (86%) of which were performed in the ED. Of these 145 patients, 57 (39%) had imaging evidence of AP. 107 patients had abdominal ultrasound (US) during their hospital course. Of 84 patients who had both CT and US, 31 (37%) patients were diagnosed with gallstones by US versus 19 (23%) by CT. Biliary dilation/obstruction was diagnosed by US in 5 (6%) patients versus 4 (5%) by CT. CT led to the correct diagnosis or change in management in 21 (14.5%) patients. CONCLUSION Early CT may alter the diagnosis or management in up to 15% of patients presenting to the ED with AP, especially older patients with prior episodes of pancreatitis and biliary interventions, however abdominal US may be a more sensitive screening study for biliary etiologies and thereby better direct further management.

Abstract
Pancreatitis is a common gastrointestinal disease with no effective therapeutic options, particularly for cases of severe acute and chronic pancreatitis (CP). Mesenchymal stromal cells (MSCs) are multipotent cells with diverse biological properties, including directional migration, paracrine, immunosuppressive, and antiinflammatory effects, which are considered an ideal candidate cell type for repairing tissue damage caused by various pathogenies. Several researchers have reported significant therapeutic efficacy of MSCs in animal models of acute and CP. However, the specific underlying mechanisms are yet to be clarified and clinical application of MSCs as pancreatitis therapy has rarely been reported. This review mainly focuses on the potential and challenges in clinical application of MSCs for treatment of acute and CP, along with discussion of the underlying molecular mechanisms.

Abstract
Acute pancreatitis (AP) is an inflammatory process of the pancreas. It is a relatively common cause of acute upper abdominal pain and is potentially associated with high morbidity and mortality. Underlying hypercalcemia as a cause of AP is very rare. We present a case of a hypercalcemia-induced acute pancreatitis with an underlying parathyroid adenoma in an 81-year-old woman with no previous symptoms of hypercalcemia. The parathyroid adenoma was semi-urgently surgically resected with normalization of calcium-levels. This case report summarizes the causes of acute pancreatitis and hypercalcemia and its management.

Abstract
Method Repeated caerulein injection was used to induce AP and chronic pancreatitis (CP) models in mice. The histopathological and serological changes were examined for evaluating the severity of the AP model, and flow cytometry was used for detecting macrophage phagocytosis and phenotype. Meanwhile, clodronate liposomes were used for macrophage depletion in mice. Finally, the CP model was adopted to further observe the protective effect of MaR1. Result MaR1 administration manifested the improved histopathological changes and the lower serum levels of amylase and lipase. However, MaR1 played no protective role in the pancreatic acinar cell line in vitro. It obviously reduced the macrophage infiltration in the injured pancreas, especially M1-type macrophages. After macrophage clearance, MaR1 showed no further protection in vivo. This study also demonstrated that MaR1 could alleviate fibrosis to limit AP progression in the CP model. Conclusion Our data suggests that MaR1 was a therapeutic and preventive target for AP in mice, likely operating through its effects on decreased macrophage infiltration and phenotype switch.
