BACKGROUND
Acute pancreatitis during pregnancy can have negative effects on both the mother and the fetus. The primary aim of this study is to evaluate the trends, maternal and fetal outcomes, and associated comorbidities of acute pancreatitis during pregnancy using data from the USA National Inpatient Sample (NIS) database.
METHODS
This study is a retrospective analysis of hospital discharge records from the NIS database from 2009 to 2019.
RESULTS
Delivery patients with acute pancreatitis faced a higher risk of maternal mortality (AOR 91.02, 95% CI 28.47-291.06), postpartum hemorrhage (AOR 1.59, 95% CI 1.02-2.49), and hypertensive complications (defined as preeclampsia, eclampsia, or HELLP syndrome) (AOR 3.42, 95% CI 2.56-4.56) compared to those without acute pancreatitis. Moreover, we saw an increased incidence of preterm labor (AOR 3.94, 95% CI 3.02-5.12) and fetal death (AOR 3.12, 95% CI 1.76-5.53). Rates of fetal restriction and large fetal size were comparable. Additionally, the acute pancreatitis group showed higher rates of acute kidney injury (4.2% vs. 0.06%; AOR, 31.02, 95% CI 12.50-76.98), severe sepsis (0.8% vs. 0.01%; AOR, 34.49, 95% CI 7.67-155.14), and respiratory failure (2.4% vs. 0.06%; AOR, 20.77, 95% CI (8.55-50.41). There were no significant differences in maternal and perinatal outcomes in biliary pancreatitis after the intervention compared to conservative treatment.
CONCLUSION
Acute pancreatitis during pregnancy can have negative effects on both the mother and fetus. Treatment for biliary pancreatitis does not affect maternal and fetal outcomes. An interdisciplinary approach is essential to ensure optimal outcomes for mothers and their offspring in these cases.

Pharmaceutical Biology Dec 2023Qingyi granules can be used to effectively treat patients with severe acute pancreatitis (SAP).
CONTEXT
Qingyi granules can be used to effectively treat patients with severe acute pancreatitis (SAP).
OBJECTIVE
To elucidate the role of gut microbiota-mediated metabolism in the therapeutic effects of Qingyi granules.
MATERIALS AND METHODS
Sprague-Dawley rats were grouped into the sham operation, SAP model, Qingyi granule intervention (Q, 1.8 g/kg) and emodin intervention (E, 50 mg/kg) groups and observed for 24 h. H&E staining and ELISA were used for histopathological analysis and serum enzyme and cytokine assays. 16S rDNA sequencing and UHPLC-HRMS were used for gut microbiota analysis and untargeted metabolomics.
RESULTS
In SAP rats, Qingyi granules decreased the pancreatic pathological score (Q, 7.4 ± 1.14; SAP, 11.6 ± 1.14, < 0.01); serum amylase (Q, 121.2 ± 6.7; SAP, 144.3 ± 8.86, < 0.05), lipase (Q, 566 ± 20.34; SAP, 656.7 ± 29.32, < 0.01), and diamineoxidase (Q, 492.8 ± 26.08; SAP, 566.1 ± 26.83, < 0.05) activities; and IL-1β (Q, 29.48 ± 0.88; SAP, 36.17 ± 1.88, < 0.01), IL-6 (Q, 112.2 ± 3.57; SAP, 128.9 ± 9.09, < 0.05) and TNF-α (Q, 215.3 ± 8.67; SAP, 266.4 ± 28.03, < 0.05) levels. SAP induced and overgrowth and suppressed and growth and caused aberrations in bacterial metabolites, which were partly reversed by Qingyi granules.
DISCUSSION AND CONCLUSIONS
Qingyi granules can modulate the gut microbiota and metabolic abnormalities to ameliorate SAP. Multi-omics approaches allow systematic study of the pharmacological mechanisms of compound prescriptions for critical illnesses.

Review
Pancreatitis is an inflammatory disease, which is triggered by adverse events in acinar cells of the pancreas. After the initial injury, infiltration of neutrophils in pancreas is observed. In the initial stages of pancreatitis, the inflammation is sterile. It has been shown that the presence of neutrophils at the injury site can modulate the disease. Their depletion in experimental animal models of the acute pancreatitis has been shown to be protective. But information on mechanism of contribution to inflammation by neutrophils at the injury site is not clear. Once at injury site, activated neutrophils release azurophilic granules containing proteolytic enzymes and generate hypochlorous acid which is a strong microbicidal agent. Additionally, emerging evidence shows that neutrophil extracellular traps (NETs) are formed which consist of decondensed DNA decorated with histones, proteases and granular and cytosolic proteins. NETs are considered mechanical traps for microbes, but there is preliminary evidence to indicate that NETs, which constitute a special mechanism of the neutrophil defence system, play an adverse role in pancreatitis by contributing to the pancreatic inflammation and distant organ injury. This review presents the overall current information about neutrophils and their role including NETs in acute pancreatitis (AP). It also highlights current gaps in knowledge which should be explored to fully elucidate the role of neutrophils in AP and for therapeutic gains.

Meta-Analysis
BACKGROUND
Scoring systems for severe acute pancreatitis (SAP) prediction should be used in conjunction with pre-test probability to establish post-test probability of SAP, but data of this kind are lacking.
OBJECTIVE
To investigate the predictive value of commonly employed scoring systems and their usefulness in modifying the pre-test probability of SAP.
METHODS
Following PRISMA statement and MOOSE checklists after PROSPERO registration, PubMed was searched from inception until September 2022. Retrospective, prospective, cross-sectional studies or clinical trials on patients with acute pancreatitis defined as Revised Atlanta Criteria, reporting rate of SAP and using at least one score among Bedside Index for Severity in Acute Pancreatitis (BISAP), Acute Physiology and Chronic Health Examination (APACHE)-II, RANSON, and Systemic Inflammatory Response Syndrome (SIRS) with their sensitivity and specificity were included. Random effects model meta-analyses were performed. Pre-test probability and likelihood ratio (LR) were combined to estimate post-test probability on Fagan nomograms. Pooled severity rate was used as pre-test probability of SAP and pooled sensitivity and specificity to calculate LR and generate post-test probability. A priori hypotheses for heterogeneity were developed and sensitivity analyses planned.
RESULTS
43 studies yielding 14,116 acute pancreatitis patients were included: 42 with BISAP, 30 with APACHE-II, 27 with Ranson, 8 with SIRS. Pooled pre-test probability of SAP ranged 16.6%-25.3%. The post-test probability of SAP with positive/negative score was 47%/6% for BISAP, 43%/5% for APACHE-II, 48%/5% for Ranson, 40%/12% for SIRS. In 18 studies comparing BISAP, APACHE-II, and Ranson in 6740 patients with pooled pre-test probability of SAP of 18.7%, post-test probability when scores were positive was 48% for BISAP, 46% for APACHE-II, 50% for Ranson. When scores were negative, post-test probability dropped to 7% for BISAP, 6% for Ranson, 5% for APACHE-II. Quality, design, and country of origin of the studies did not explain the observed high heterogeneity.
CONCLUSIONS
The most commonly used scoring systems to predict SAP perform poorly and do not aid in decision-making.

Meta-Analysis Review
The risk of recurrent pancreatitis after first episode of acute pancreatitis in relation to etiology and severity of disease: A systematic review, meta-analysis and meta-regression analysis.
BACKGROUND AND AIM
The study aims to determine and quantify the stratified risk of recurrent pancreatitis (RP) after the first episode of acute pancreatitis in relation to etiology and severity of disease.
METHODS
A systematic review and meta-analysis in compliance with PRISMA statement standards was conducted. A search of electronic information sources was conducted to identify all studies investigating the risk of RP after the first episode of acute pancreatitis. Proportion meta-analysis models using random effects were constructed to calculate the weighted summary risks of RP. Meta-regression was performed to evaluate the effect of different variables on the pooled outcomes.
RESULTS
Analysis of 57,815 patients from 42 studies showed that the risk of RP after first episode was 19.8% (95% confidence interval [CI] 17.5-22.1%). The risk of RP was 11.9% (10.2-13.5%) after gallstone pancreatitis, 28.7% (23.5-33.9%) after alcohol-induced pancreatitis, 30.3% (15.5-45.0%) after hyperlipidemia-induced pancreatitis, 38.1% (28.9-47.3%) after autoimmune pancreatitis, 15.1% (11.6-18.6%) after idiopathic pancreatitis, 22.0% (16.9-27.1%) after mild pancreatitis, 23.9% (12.9-34.8%) after moderate pancreatitis, 21.6% (14.6-28.7%) after severe pancreatitis, and 6.6% (4.1-9.2%) after cholecystectomy following gallstone pancreatitis. Meta-regression confirmed that the results were not affected by the year of study (P = 0.541), sample size (P = 0.064), length of follow-up (P = 0.348), and age of patients (P = 0.138) in the included studies.
CONCLUSIONS
The risk of RP after the first episode of acute pancreatitis seems to be affected by the etiology of pancreatitis but not the severity of disease. The risks seem to be higher in patients with autoimmune pancreatitis, hyperlipidemia-induced pancreatitis, and alcohol-induced pancreatitis and lower in patients with gallstone pancreatitis and idiopathic pancreatitis.

BACKGROUND
Splanchnic vein thrombosis (SVT) is a well-recognised though little-studied complication in acute pancreatitis (AP). SVT risk factors, its clinical consequences and the role of anticoagulation (AC) therapy is scarce.
AIMS
To evaluate the incidence and natural history of SVT in AP.
METHODS
Post hoc analysis of a prospective multicentre cohort study involving 23 hospitals in Spain. AP complications were identified by computer tomography, and patients with SVT were re-evaluated after two years.
RESULTS
A total of 1655 patients with AP were included. The overall incidence of SVT was 3.6%. SVT was significantly associated with male gender, younger age and alcoholic aetiology. Every local complication increased SVT incidence, and this risk rose gradually with larger extension and infection of necrosis. These patients had a longer hospital stay and underwent a greater number of invasive treatments, regardless of AP severity. Forty-six patients with SVT were followed up. SVT resolution rate was 54.5% in the AC group and 30.8% in the non-AC group with lower thrombotic complications in the SVT resolution group (83.3% vs 22.7%; p<0.001). No AC-related adverse events occurred.
CONCLUSION
This study identifies the risk factors and negative clinical impact of SVT in AP. Our results justify future trials to demonstrate the role of AC in this clinical scenario.

BACKGROUND
Immune checkpoint inhibitor-induced pancreatic injury (ICI-PI) ranges from asymptomatic hyperlipasemia to symptomatic acute pancreatitis (AP). The proportion of pancreatic injury while receiving ICIs that is attributable to therapy remains unclear. We evaluated the etiology of hyperlipasemia in patients receiving ICIs, and the clinical characteristics, management, and outcomes of ICI-PI.
PATIENTS AND METHODS
We assessed 6,450 consecutive adult patients with cancer who received ICI doses between 2011 and 2019, 364 of whom had at least 1 instance of elevated serum lipase after ICI initiation and were included in our trial. Primary outcomes were the development of ICI-PI and ICI-induced acute pancreatitis (ICI-AP).
RESULTS
Pancreatic injury was attributable to ICI use in 105 individuals (29% of those with hyperlipasemia; 1.6% overall). Of 27 patients with ICI-AP, 4 (15%) presented asymptomatically with hyperlipasemia and pancreatic inflammation on imaging. In multivariable regression, the presence of other immune-related adverse events was positively associated with ICI-AP (≥2 events: odds ratio, 5.43; 95% CI, 1.47-26.03). Compared with patients with other ICI-PI, those with ICI-AP more frequently required steroids (74% vs 4%), intravenous fluids (85% vs 10%), hospitalization (89% vs 9%), and permanent cessation of ICIs due to pancreatic injury (70% vs 3%), and less frequently continued therapy uninterrupted (0% vs 40%) (P<.01 for all). Of the 105 patients, 3 (3%) developed exocrine insufficiency and 9 (9%) developed endocrine insufficiency, which were concentrated among those with ICI-AP.
CONCLUSIONS
A minority of occurrences of pancreatitis and hyperlipasemia in patients receiving ICIs are due to these therapies, supporting NCCN recommendations to exclude alternative etiologies. Because a notable proportion of patients with ICI-AP were asymptomatic but warranted treatment per current guidelines, abdominal imaging is diagnostically valuable in those with significant hyperlipasemia. Patients with ICI-AP should be monitored for exocrine pancreatic insufficiency. Many with hyperlipasemia who do not meet the criteria for AP can continue therapy uninterrupted.

Observational Study
OBJECTIVE
The existing literature on the combination of acute pancreatitis (AP) and COVID-19 is scarce. The objective of our study is to compare the clinical outcomes and occurrence of long COVID syndrome in AP patients with and without COVID-19, while investigating the potential impact of COVID-19 on the severity, mortality rate, and long COVID syndrome in these patients.
METHODS
This retrospective, observational study was conducted at a single center. It included patients aged 18 years and above who were diagnosed with AP during the pandemic. Patients were categorized into two groups based on the results of RT-qPCR testing: the SARS-CoV-2-positive group and the SARS-CoV-2-negative group. The study aimed to compare the severity of AP, mortality rate, and occurrence of long COVID syndrome between these two groups.
RESULT
A retrospective review was conducted on 122 patients diagnosed with acute pancreatitis between December 1, 2022, and January 31, 2023. Out of these patients, 100 were included in the study. The analysis revealed no significant differences in mortality rate, severity, and sequelae between AP patients with COVID-19 and those without COVID-19 (p > 0.005). However, a statistically significant difference was observed in the occurrence of long COVID syndrome, specifically in the presence of cough (p = 0.04).
CONCLUSION
This study demonstrates that the presence of COVID-19 in patients with pancreatitis does not lead to an increase in the mortality and severity rate of pancreatitis.

Acute pancreatitis (AP) is an inflammatory disease of the pancreas. Iron is an essential element for life and is involved in many metabolic processes. Ferroptosis is a type of regulated cell death that is triggered by iron and oxidative stress. A well-established mouse AP model was adopted to study the role of iron and ferroptosis in the pathogenesis of pancreatitis. Mice were injected with cerulein to induce AP, and pancreatic tissue samples were analyzed to determine the pathology, cell death, iron deposition, expression of iron transporters, and lipid peroxidation. The role of iron was studied by giving mice extra iron or iron chelator. In vitro studies with acinar cells with ferroptosis activator and inhibitor were also performed to assess the inflammatory response. Iron was found accumulated in the pancreatic tissue of mice who suffered cerulein-induced pancreatitis. Cell death and lipid peroxidation increased in these tissues and could be further modulated by iron dextran or iron chelator. Mice given Hemin through gavage had reduced levels of GSH in pancreatic tissue and increased inflammatory response. Studies with acinar cells showed increased levels of lipid peroxidation and ferroptosis-specific mitochondrial damage when treated with ferroptosis inducer and inflammatory cytokines.

Review
Pancreatic fluid collections (PFCs) typically develop as local complications of acute pancreatitis and complicate the clinical course of patients with acute pancreatitis and potentially fatal clinical outcomes. Interventions are required in cases of symptomatic walled-off necrosis (WON) (matured PFCs with necrosis) and pancreatic pseudocysts (matured PFCs without necrosis). In the management of necrotizing pancreatitis and WON, endoscopic ultrasound-guided transluminal drainage combined with on-demand endoscopic necrosectomy (i.e. the step-up approach) is increasingly used as a less invasive treatment modality compared with a surgical or percutaneous approach. Through the substantial research efforts and development of specific devices and stents (e.g. lumen-apposing metal stents), endoscopic techniques of PFC management have been standardized to some extent. However, there has been no consensus about timing of carrying out each treatment step; for instance, it is uncertain when direct endoscopic necrosectomy should be initiated and finished and when a plastic or metal stent should be removed following clinical treatment success. Despite emerging evidence for the effectiveness of noninterventional supportive treatment (e.g. antibiotics, nutritional support, irrigation of the cavity), there has been only limited data on the timing of starting and stopping the treatment. Large studies are required to optimize the timing of those treatment options and improve clinical outcomes of patients with PFCs. In this review, we summarize the current available evidence on the indications and timing of interventional and supportive treatment modalities for this patient population and discussed clinical unmet needs that should be addressed in future research.
