Infectious etiologies are rare cause of acute pancreatitis (AP). We sought to investigate the frequency of viral-attributed AP (VIAP) and describe its natural course and clinical features. Comprehensive review of PubMed and EMBASE in English until December 31, 2019, was performed. AP diagnosis and severity were defined per the Revised Atlanta Classification. Viral infections were diagnosed by serology and/or histology. A diagnosis of viral infection, with a concurrent AP diagnosis, a temporal resolution of both entities, and the attempt to exclude the most common etiologies of AP defined VIAP. Two independent reviewers reviewed eligible publications. Bias risk was assessed with the Murad tool. A total of 209 cases identified in 128 publications met inclusion criteria. Mean age was 38.9 ± 1.28 years. Male-to-female ratio was 2.2:1, and 28% of patients were immunocompromised. Viral hepatitis (A, B, C, D and E) was the most common virus and accounted for 34.4% of cases, followed by coxsackie and echoviruses (14.8%), hemorrhagic fever viruses (12.4%), CMV (12.0%), VZV (10.5%), mumps and measles (3.8%), primary HIV infection (3.8%), HSV (1.9%), EBV (1.9%), and the remainder of cases (2.9%) attributed to adenovirus, influenza H1N1, and multiple viruses. Severity of AP was: 43.1% mild, 11.7% moderately severe, 32.4% severe. Death occurred in 42 (20.1%) patients. A significant portion of VIAP patients were immunocompromised (28.0%) and accounted for 71.4% of mortality cases. Mortality was higher than that reported for AP from other etiologies in the literature.

OBJECTIVES
Hypercalcemia of malignancy confers a poor prognosis. This systematic review evaluated published cases of hypercalcemia of malignancy presenting with acute pancreatitis (AP), in terms of clinical presentation and outcomes.
METHODS
A comprehensive review of PubMed and Embase until March 18, 2020, was conducted. Studies were included if they reported on patients with hypercalcemia of malignancy and AP with attempts to exclude other etiologies of hypercalcemia and AP. Two independent reviewers selected and appraised studies using the Murad tool.
RESULTS
Thirty-seven cases were identified. Mean (standard deviation) age was 44.8 (2.46) years. Mean (standard deviation) presenting corrected calcium was 14.5 (0.46) mg/dL. Parathyroid carcinoma (21.6%) and multiple myeloma (21.6%) were the most common malignancies. Cases were classified as severe (37.8%), mild (21.6%), and moderately severe (18.9%), whereas 21.6% did not report severity. Necrotizing pancreatitis developed in 21.6% of cases. Most cases were treated with intravenous hydration and bisphosphonates or calcitonin/calcitonin analogues. Mortality was 32.4% during the same presentation of AP. Among mortality cases, 10 of 12 had severe AP, and 5 of 12 had necrotizing pancreatitis. Degree of hypercalcemia did not influence mortality.
CONCLUSION
Acute pancreatitis associated with hypercalcemia of malignancy is rare. One in 3 patients with this presentation may not survive AP.

Review
Acute pancreatitis is an acute inflammatory process of the pancreas with high prevalence and varying degrees of severity that can be potentially life-threatening. Much is still unknown about which mechanisms determine the course and severity of acute pancreatitis. The primary objective of this review is to identify the potential association between circulating lymphocytes and the severity of acute pancreatitis. A systematic search was performed in Medline, Web of Science, Cochrane Central Register of Controlled Trials and ClinicalTrails.gov. The authors independently did the selection process as well as data extraction that was recorded into a flow diagram following the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P). Our initial search identified 27,783 studies which were narrowed down to 13 by applying strict inclusion and exclusion algorithms. The consistent findings across the studies indicated that peripheral blood lymphocytes are related to acute pancreatitis severity.

Review
Long-term medication with valproic acid has been associated with acute pancreatitis. The purpose of this report is to gain insight into the features of this pancreatitis. A preregistered literature search (CRD42023438294) was performed on the National Library of Medicine, Excerpta Medica, Web of Science, and Google Scholar. Patients with alcohol abuse disorder, gallstone disease, hypertriglyceridemia or hypercalcemia, patients with acute valproic acid intoxication, and patients with a pre-existing pancreatitis were excluded. For the final analysis, we retained 73 reports published between 1979 and 2023, which described 125 subjects (83 children and 42 adults predominantly affected by an epilepsy) with an acute pancreatitis related to valproic acid. The diagnosis was made 11 (3.0-24) months (median and interquartile range) after starting valproic acid. One hundred and five cases (84%) recovered and twenty (16%) died. Sex, age, dosage or circulating level of valproic acid, latency time, prevalence of intellectual disability, and antiepileptic co-medication were similar in cases with and without a lethal outcome. Nineteen subjects were rechallenged with valproic acid after recovery: sixteen (84%) cases developed a further episode of pancreatitis. In conclusion, pancreatitis associated with valproic acid presents at any time during treatment and has a high fatality rate.

Review
OBJECTIVES
Cannabis is the most frequently consumed illicit drug in the world, with higher prevalence under the age of 35 years. Cannabis was first reported as a possible cause of acute pancreatitis (AP) in 2004. The aim of this systematic review is to examine cannabis use as an etiology of AP.
METHODS
A search using PubMed/Medline, Embase, Scopus, and Cochrane was performed without language or year limitations to May 1, 2016. Search terms were "Cannabis" and "Acute Pancreatitis" with all permutations. The search yielded 239 results. Acute pancreatitis was defined by meeting 2 of 3 Revised Atlanta Classification criteria. Cannabis-induced AP was defined by preceding use of cannabis and exclusion of common causes of AP when reported. Sixteen papers met inclusion criteria dating from 2004 to 2016.
RESULTS
There were 26 cases of cannabis-induced AP (23/26 men; 24/26 under the age of 35 y). Acute pancreatitis correlated with increased cannabis use in 18 patients. Recurrent AP related temporally to cannabis use was reported in 15 of 26. There are 13 reports of no further AP episodes after cannabis cessation.
CONCLUSIONS
Cannabis is a possible risk factor for AP and recurrent AP, occurring primarily in young patients under the age of 35 years. Toxicology screens should be considered in all patients with idiopathic AP.

Review
INTRODUCTION
Acute pancreatitis (AP) is a common clinical pancreatic disease. Patients with different severity levels have different clinical outcomes. With the advantages of algorithms, machine learning (ML) has gradually emerged in the field of disease prediction, assisting doctors in decision-making.
METHODS
A systematic review was conducted using the PubMed, Web of Science, Scopus, and Embase databases, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Publication time was limited from inception to 29 May 2021. Studies that have used ML to establish predictive tools for AP were eligible for inclusion. Quality assessment of the included studies was conducted in accordance with the IJMEDI checklist.
RESULTS
In this systematic review, 24 of 2,913 articles, with a total of 8,327 patients and 47 models, were included. The studies could be divided into five categories: 10 studies (42%) reported severity prediction; 10 studies (42%), complication prediction; 3 studies (13%), mortality prediction; 2 studies (8%), recurrence prediction; and 2 studies (8%), surgery timing prediction. ML showed great accuracy in several prediction tasks. However, most of the included studies were retrospective in nature, conducted at a single centre, based on database data, and lacked external validation. According to the IJMEDI checklist and our scoring criteria, two studies were considered to be of high quality. Most studies had an obvious bias in the quality of data preparation, validation, and deployment dimensions.
CONCLUSION
In the prediction tasks for AP, ML has shown great potential in assisting decision-making. However, the existing studies still have some deficiencies in the process of model construction. Future studies need to optimize the deficiencies and further evaluate the comparability of the ML systems and model performance, so as to consequently develop high-quality ML-based models that can be used in clinical practice.

Review
There is increasing literature mentioning severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection (COVID-19 infection) causing acute pancreatitis (AP). It is hypothesized that SARS-Cov-2 causes pancreatic injury either by direct cytotoxic effect of the virus on pancreatic cells through the angiotensin-converting enzyme 2 (ACE2) receptors - the main receptors for the virus located on pancreatic cells - or by the cytokine storm that results from COVID-19 infection or a component of both. Many viruses are related to AP including mumps, coxsackievirus, cytomegalovirus (CMV), Epstein-Barr virus (EBV), and as data evolves SARS-CoV-2 virus may be one of them as well. We conducted a systematic literature review to explore the current literature and provide an overview of the evidence of AP in COVID-19 infection. We studied the presence of AP in patients with SARS-CoV-2 infection and calculated the time of diagnosis of SARS-CoV-2 infection with respect to the time of diagnosis of AP. We also studied the age, gender, clinical manifestations, time of onset of symptoms, laboratory values, imaging findings, mortality, length of stay, comorbidities, need for Intensive Care Unit (ICU) care, and excluded any other common causes of AP. We included 40 articles comprising 46 patients. All patients had a positive SARS-CoV-2 polymerase chain reaction (PCR) test and all patients had AP as per Atlanta's criteria. The most common clinical presentation was abdominal pain in 29 (63.0%). Edematous pancreas was the most common Computed Tomography Abdomen Pelvis (CTAP) scan finding in these patients (35 patients). Seventeen (37%) patients required ICU admission and six (13%) patients died. Our study provides an important overview of the available data on AP in COVID-19 patients and concludes that AP is an important complication in COVID-19 infection and should be considered as an important differential in patients with COVID-19 infection who complain of abdominal pain.

Meta-Analysis Review
OBJECTIVES
This study systematically explores the prevalence of pancreatic exocrine insufficiency (PEI) after acute pancreatitis in different subgroups of etiology (biliary/alcoholic/other), disease severity and follow-up time (<12, 12-36 and > 36 months after index admission).
METHODS
PubMed and EMBASE databases were searched, 32 studies were included in this study level meta-analysis.
RESULTS
In a total of 1495 patients with acute pancreatitis, tested at a mean of 36 months after index admission, the pooled prevalence of PEI was 27.1% (95%-confidence interval [CI]: 20.3%-35.1%). Patients from seven studies (n = 194) underwent direct tests with pooled prevalence of 41.7% [18.5%-69.2%]. Patients from 26 studies (n = 1305) underwent indirect tests with pooled prevalence of 24.4% [18.3%-31.8%]. In subgroup analyses on patients that underwent fecal elastase-1 tests, PEI occurred more often in alcoholic pancreatitis (22.7% [16.6%-30.1%]) than in biliary pancreatitis (10.2% [6.2%-16.4%]) or other etiology (13.4% [7.7%-22.4%]; P = 0.02). Pooled prevalence of PEI after mild and severe pancreatitis was 19.4% [8.6%-38.2%] and 33.4% [22.6%-46.3%] respectively in studies using fecal elaste-1 tests (P = 0.049). Similar results were seen in patients without (18.9% [9.3%-34.6%]) and with necrotizing pancreatitis (32.0% [18.2%-49.8%]; P = 0.053). Over time, the prevalence of PEI decreased in patients who underwent the fecal elastase-1 test and increased in patients who underwent the fecal fat analysis.
CONCLUSIONS
After acute pancreatitis, a quarter of all patients develop PEI during follow-up. Alcoholic etiology and severe and necrotizing pancreatitis are associated with higher risk of PEI. The prevalence of PEI may change as time of follow-up increases.

OBJECTIVE
In up to 20% of patients, the aetiology of acute pancreatitis (AP) remains elusive and is thus called idiopathic. On more detailed review these cases can often be explained through biliary disease and are amenable to treatment. Findings range from biliary sludge to microlithiasis but their definitions remain fluid and controversial.
DESIGN
A systematic literature review (1682 reports, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines) analysed definitions of biliary sludge and microlithiasis, followed by an online international expert survey (30 endoscopic ultrasound/hepatobiliary and pancreatic experts; 36 items) which led to definitions of both. These were consented by Delphi voting and clinically evaluated in a retrospective cohort of patients with presumed biliary pancreatitis.
RESULTS
In 13% of original articles and 19.2% of reviews, microlithiasis and biliary sludge were used synonymously. In the survey, 41.7% of experts described the term 'sludge' and 'microlithiasis' as identical findings. As a consequence, three definitions were proposed, agreed on and confirmed by voting to distinctly discriminate between biliary sludge (hyperechoic material without acoustic shadowing) and microlithiasis (echorich calculi of ≤5 mm with acoustic shadowing) as opposed to larger biliary stones, both for location in gallbladder and bile ducts. In an initial attempt to investigate the clinical relevance in a retrospective analysis in 177 confirmed cases in our hospital, there was no difference in severity of AP if caused by sludge, microlithiasis or stones.
CONCLUSION
We propose a consensus definition for the localisation, ultrasound morphology and diameter of biliary sludge and microlithiasis as distinct entities. Interestingly, severity of biliary AP was not dependent on the size of concrements warranting prospective randomised studies which treatment options are adequate to prevent recurrence.

Review
BACKGROUND
Inflammatory bowel disease (IBD) is a chronic inflammatory immune-mediated disorder of the gut with frequent extra-intestinal complications. Pancreatic involvement in IBD is not uncommon and comprises a heterogeneous group of conditions, including acute pancreatitis (AP), chronic pancreatitis (CP), autoimmune pancreatitis (AIP) and pancreatic exocrine insufficiency (PEI); however, data on such an association remain sparse and heterogeneous.
METHOD
PubMed/MEDLINE and EMBASE databases were searched for studies investigating pancreatic involvement in patients with IBD.
RESULTS
Four thousand one hundred and twenty-one records were identified and 547 screened; finally, 124 studies were included in the review. AP is the most frequent pancreatic manifestation in IBD; the majority of AP cases in IBD are due to gallstones and drugs but cases of idiopathic AP are increasingly reported. AIP is a rare disease, but a strong association with IBD has been demonstrated, especially for type 2 and ulcerative colitis. The pathogenetic link between IBD and AIP remains unclear, but an immune-mediated pathway seems plausible. An association between CP and PEI with IBD has also been suggested, but data are to date scarce and conflicting.
CONCLUSION
This is the first systematic review of the association between IBD and pancreatic diseases. Gallstones and drugs should be considered the most probable causes of AP in IBD, with type 2 AIP also being possible.
