Background: Total pancreatectomy with islet autotransplantation (TPIAT) is a potentially curative treatment for patients with chronic pancreatitis (CP) refractory to medical and endoscopic therapies. Patients often receive the initial follow‐up medical care at the surgery‐performing center, but then may follow up closer to where they live. We sought to describe the characteristics and outcomes of pediatric patients who underwent TPIAT at a national surgical referral center and were subsequently followed at our regional subspecialty center, the Children's Hospital Colorado. Methods: We performed a retrospective analysis of baseline and outcomes data for the 10 pediatric patients who underwent TPIAT from 2007 to 2020 and received follow‐up care at our institution. Results: All patients had a diagnosis of CP, and nine of 10 patients had an identified underlying genetic risk factor. Insulin usage was common immediately following TPIAT, but at 1 year of follow‐up, five of nine patients (55.6%) were insulin‐independent and nine of nine had an HbA1c below 6.5%. For the four patients on insulin 1 year after TPIAT, total daily insulin dose ranged from 0.06 to 0.71 units/kg/day. All patients who underwent mixed meal tolerance testing had a robust peak C‐peptide response at 1 year. There were significant improvements in nausea, school/work absences, narcotic dependence, and pancreas‐related hospital admissions 1 year after TPIAT. Conclusions: Patients followed at our center had long‐term improvements with low‐insulin usage, detectable C‐peptide, and improved pancreatitis‐related outcomes after TPIAT. Pediatric patients who undergo TPIAT can be successfully co‐managed in conjunction with the original surgery‐performing center. [ABSTRACT FROM AUTHOR]

ObjectiveThe aim of the study was to determine whether clinical characteristics and management of pediatric acute recurrent pancreatitis (ARP) and chronic pancreatitis (CP) differ across INSPPIRE (INternational Study Group of Pediatric Pancreatitis: In Search for a cuRE) sites.Study designData were collected from INSPPIRE and analyzed per US regions and "non-US" sites. Between-group differences were compared by Pearson chi-square test. Differences in disease burden were compared by Kruskal-Wallis test.ResultsOut of the 479 subjects, 121 (25%) were enrolled in West, 151 (32%) Midwest, 45 Northeast (9%), 78 (16%) South, and 84 (18%) at non-US sites. Hispanic ethnicity was more common in South (P

OBJECTIVES:Adults with chronic pancreatitis (CP) have a high risk for developing pancreatogenic diabetes mellitus (DM), but little is known regarding potential risk factors for DM in children with acute recurrent pancreatitis (ARP) or CP. We compared demographic and clinical features of children with ARP or CP, with and without DM, in the INternational Study Group of Pediatric Pancreatitis: In Search of a CuRE (INSPPIRE) registry. METHODS:We reviewed the INSPPIRE database for the presence or absence of physician-diagnosed DM in 397 children, excluding those with total pancreatectomy with islet autotransplantation, enrolled from August 2012 to August 2017. Patient demographics, body mass index percentile, age at disease onset, disease risk factors, disease burden, and treatments were compared between children with DM (n = 24) and without DM (n = 373). RESULTS:24 children (6.0% of the cohort) had a diagnosis of DM. Five of 13 tested were positive for beta cell autoantibodies. The DM group was 4.2 years (95% CI 3.0, 5.4) older at first episode of acute pancreatitis, and tended to more often have hypertriglyceridemia (odds ratio (OR) 5.21 (1.33, 17.05)), coexisting autoimmune disease (OR 3.94 (0.88, 13.65)) or pancreatic atrophy (OR 3.64 (1.13, 11.59)). CONCLUSIONS:Pancreatic atrophy may be more common among children with DM, suggesting more advanced exocrine disease. However, data in this exploratory cohort also suggest increased autoimmunity and hypertriglyceridemia in children with DM, suggesting that risk factors for Type 1 and Type 2 DM respectively may play a role in mediating DM development in children with pancreatitis.

ObjectiveThe aim of the study was to determine the rate of progression from acute recurrent pancreatitis (ARP) to chronic pancreatitis (CP) in children and assess risk factors.Study designData were collected from the INternational Study group of Pediatric Pancreatitis: In search for a cuRE (INSPPIRE) cohort. Kaplan-Meier curves were constructed to calculate duration of progression from initial attack of acute pancreatitis (AP) to CP. Log-rank test was used to compare survival (nonprogression) probability distribution between groups. Cox proportional hazard regression models were fitted to obtain hazard ratio (with 95% confidence interval [CI]) of progression for each risk variable.ResultsOf 442 children, 251 had ARP and 191 had CP. The median time of progression from initial attack of AP to CP was 3.79 years. The progression was faster in those ages 6 years or older at the first episode of AP compared to those younger than 6 years (median time to CP: 2.91 vs 4.92 years; P = 0.01). Children with pathogenic PRSS1 variants progressed more rapidly to CP compared to children without PRSS1 variants (median time to CP: 2.52 vs 4.48 years; P = 0.003). Within 6 years after the initial AP attack, cumulative proportion with exocrine pancreatic insufficiency was 18.0% (95% CI: 12.4%, 25.6%); diabetes mellitus was 7.7% (95% CI: 4.2%, 14.1%).ConclusionsChildren with ARP rapidly progress to CP, exocrine pancreatic insufficiency, and diabetes. The progression to CP is faster in children who were 6 years or older at the first episode of AP or with pathogenic PRSS1 variants. The factors that affect the aggressive disease course in childhood warrant further investigation.

IntroductionPediatric acute pancreatitis (PAP) has an increasing incidence and is now estimated to be almost as common as in adults. Up to 30% of patients with PAP will develop moderate or severe disease course (M/SPAP), characterized by organ failure, local or systemic complications. There is still no consensus regarding on-admission severity prediction in these patients. Our aim was to conduct a systematic review and meta-analysis of available predictive score systems and parameters, and differences between on-admission parameters in mild and M/SPAP.MethodsWe conducted a systematic search on the 14th February, 2022 in MEDLINE, Embase and CENTRAL. We performed random-effects meta-analysis of on-admission differences between mild and M/SPAP in laboratory parameters, etiology, demographic factors, etc. calculating risk ratios (RR) or mean differences (MD) with 95% confidence intervals (CI) and created forest plots. For the meta-analysis of predictive score systems, we generated hierarchical summary receiver operating characteristic curves using a bivariate model. Chi-squared tests were performed and I2 values calculated to assess statistical heterogeneity.ResultsWe included 44 studies – mostly retrospective cohorts – in our review. Among predictive score systems examined by at least 5 studies, the modified Glasgow scale had the highest specificity (91.5% for values ≥3), and the Pediatric Acute Pancreatitis Severity score the highest sensitivity (63.1% for values ≥3). The performance of other proposed score systems and values were summarized. Traumatic (RR: 1.70 95% CI: 1.09–2.67) and drug–induced (RR: 1.33 95% CI: 0.98–1.87) etiologies were associated with a higher rate of M/SPAP, while anatomical (RR: 0.6195% CI: 0.38–0.96) and biliary (RR: 0.72 95% CI: 0.53–0.99) PAP tended to be less severe.DiscussionMany predictive score systems were proposed to assess the possibility of M/SPAP course. The most commonly used ones exhibit good specificity, but subpar sensitivity. Our systematic review provides a rigorous overview of predictive options assessed thus far, that can serve as a basis for future improvement of scores via the addition of parameters with a better observed sensitivity: e.g., lipase exceeding 7-times the upper threshold, hemoglobin, etc. The addition of etiological factors is another possibility, as they can herald a more severe disease course.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?RecordID=307271, PROSPERO, identifier: CRD42022307271.

Pancreatitis is an inflammatory pancreatic disease; common etiologies include infection, anatomic abnormalities, biliary, inborn errors of metabolism, trauma, and rarely malignancy. Primary mediastinal large B-cell lymphoma commonly presents in younger women with principally mediastinal involvement. We report the first documented case of a pediatric patient presenting with acute pancreatitis secondary to metastatic primary mediastinal large B-cell lymphoma. Since diagnosis, the patient underwent a combination of chemotherapy and immunotherapy treatments, and the tumor burden had decreased significantly. Malignancy is a rare documented presentation of acute pancreatitis in the pediatric population, and it should be included in a broad differential diagnosis., (© 2024 The Author(s).

Acute pancreatitis (AP) is emerging in pediatrics. A subset of children with AP progresses to acute recurrent pancreatitis (ARP) and chronic pancreatitis (CP). The role of extensive gene testing in the progression has not been investigated previously. We have followed children enrolled in the registry and at our center for progression to ARP and CP after the first attack. This study utilizes an extensive gene sequencing panel as a platform to evaluate the role of genetics in first attack AP, and the progression over time, from first attack to ARP and CP in children. Genes, with corresponding variants were involved in the 3 groups studied: AP, ARP and CP. We have shown that the presence of gene variants from the eight tested genes is enriched in the CP group compared to the AP and ARP groups. The presence of more than one gene was associated with CP (p = 0.01). SPINK1 mutation(s) was significantly associated with faster progression to ARP, (p = 0.04). Having a variant from CFTR, SPINK1 or PRSS1, was associated with the faster progression from AP to CP over time (p < 0.05). This study shows that genetics have a significant role in progression to ARP and CP from the first attack of pancreatitis. [ABSTRACT FROM AUTHOR]

Pancreatitis-Panniculitis-Polyarthritis (PPP) syndrome is rare and its physiopathology unclear. A 6-year old boy suffered of traumatic pancreatitis complicated by PPP syndrome. Extensive investigations demonstrated high levels of pancreatic lipase and fatty acids in the affected peripheral tissues. These findings support the sequence of peripheral lipolysis and fatty acid accumulation inducing tissue inflammation.

Pediatric Pancreatitis has gained a lot of attention in the last decade. Updates in medical management include new testing technologies in genetics, function testing and imaging modalities. Updates in surgical management have taken place as well, with total pancreatectomy islet auto transplantation reserved for a specific patient population that meets the clinical criteria. Multidisciplinary team management is needed for patients with chronic pancreatitis to ensure optimal outcomes. [ABSTRACT FROM AUTHOR]

Background Pediatric pancreatitis is an underdiagnosed disease with variable etiology. In the past 10–15 years the incidence of pediatric pancreatitis has increased, it is now 3.6–13.3 cases per 100,000 children. Up-to-date evidence based management guidelines are lacking for the pediatric pancreatitis. The European Pancreatic Club, in collaboration with the Hungarian Pancreatic Study Group organized a consensus guideline meeting on the diagnosis and management of pancreatitis in the pediatric population. Methods Pediatric Pancreatitis was divided into three main clinical categories: acute pancreatitis, acute recurrent pancreatitis and chronic pancreatitis. Fifteen relevant topics (acute pancreatitis: diagnosis; etiology; prognosis; imaging; complications; therapy; biliary tract management; acute recurrent pancreatitis: diagnosis; chronic pancreatitis: diagnosis, etiology, treatment, imaging, intervention, pain, complications; enzyme replacement) were defined. Ten experts from the USA and Europe reviewed and summarized the available literature. Evidence was classified according to the GRADE classification system. Results Within fifteen topics, forty-seven relevant clinical questions were defined. The draft of the updated guideline was presented and discussed at the consensus meeting held during the 49th Meeting of European Pancreatic Club, in Budapest, on July 1, 2017. Conclusions These evidence-based guidelines provides the current state of the art of the diagnosis and management of pediatric pancreatitis. [ABSTRACT FROM AUTHOR]

Background/Objectives Approximately 15–20% of pediatric patients with acute pancreatitis (AP) develop severe disease. Severity scoring tools were developed for adult patients, but have limitations when applied in children. We aimed to identify early predictors of severe acute pancreatitis (SAP) on hospital admission for early risk stratification of patients. Methods Retrospective review of AP admissions was conducted. The derivation cohort included cases at Cincinnati Children's Hospital Medical Center (CCHMC) between 2009 and 2013. Clinical data collected during the first 24 h of admission were analyzed and a predictive model was derived through statistical analysis. The performance of the model was evaluated in a validation cohort from 2 more institutions other than CCHMC. Results In the derivation cohort 19% of the 284 admissions were SAP. A generalized linear mixed effect model analysis revealed that lipase, albumin and white blood count (WBC) play a role in the development of SAP (area under the receiver operating curve (AUROC 0.76)). In the validation cohort of 165 AP cases, SAP ranged from 8 to 20% at the three institutions. Performance of the model in this cohort was comparable to the derivation model (AUROC 0.77). There were 369 encounters in the combined derivation and validation pool (AUROC 0.76). Conclusions The prognostic severity tool with 3 variables (lipase, albumin, and WBC) obtained within 24 h of admission can be applied to predict SAP in pediatric patients. [ABSTRACT FROM AUTHOR]

Background: There are unexpectedly large differences between the incidences of acute pancreatitis (AP) as indicated by different hospitals. Retrospective studies suggest that the reason behind this is the large differences that exist between the local managements of abdominal pain at emergency units. Unfortunately, no evidence-based medicine (EBM) guidelines are available to give proper instruction concerning the necessity of serum pancreatic enzyme measurement during abdominal pain. Summary: Pain in Early Phase of Pediatric Pancreatitis (PINEAPPLE) is an observational, multinational observational clinical trial to explore the route from the first sign of abdominal pain to the diagnosis of pancreatitis (PINEAPPLE trial). The PINEAPPLE-R subtrial is a retrospective review on the records of children (patients under 18) appearing at emergency units - a review of their clinical symptoms, results of imaging examinations and laboratory parameters. The PINEAPPLE-P subtrial is a prospective trial designed to develop a fast and simple EBM guideline that helps to evaluate (in a reliable and cost-efficient way) the necessity of pancreatic enzyme test and abdominal ultrasonography (or even computed tomography) when a child has abdominal pain. The trial has been registered at the ISRCTN registry and has received the relevant ethical approval. Key Message: The PINEAPPLE trial will help to recognize AP in children in a highly efficient manner. [ABSTRACT FROM AUTHOR]

Background: Single-centered studies show increased number of acute pancreatitis (AP) in children. Here, the Pediatric Section of the Hungarian Pancreatic Study Group introduces an international observational clinical trial (APPLE) to collect a critical mass of clinical data and biomedical research samples in a uniform prospective manner. Summary: The APPLE-R is for patients under 18 years of age with a history of pancreatitis. The study primarily provides information on possible genetic variants behind the disease and their impact on the prognosis. The APPLE-P is for patients under 18 years of age with a diagnosis of AP. Children with AP diagnosed based on the fulfillment of '2 out of 3' of the Atlanta criteria will be selected. This subtrial requests detailed information from the medical history, etiology, complains and symptoms, physical examinations, laboratory parameters, imaging, immediate therapy at admission and complications of the disease. The APPLE trial has been registered at the ISRCTN registry and has received the relevant ethical approval. The study is open for all pediatric centers throughout the world. Key Message: This is the first worldwide study tracking earlier (APPLE-R) and ongoing episodes (APPLE-P) of pancreatitis. [ABSTRACT FROM AUTHOR]

Pediatric pancreatitis describes a spectrum covering acute pancreatitis, acute recurrent pancreatitis, and chronic pancreatitis, each with varying clinical manifestations and risk factors requiring a tailored diagnostic approach. We emphasize management strategies based on age, risk factors, recurrence, and complications. A discussion of the role of therapeutic endoscopy is reviewed and highlights the growing role of endoscopic ultrasound and endoscopic retrograde cholangiopancreatography in children with pancreatitis. Particular diagnostic challenges in autoimmune pancreatitis are reviewed with an emphasis on differentiating this entity from alternate pancreaticobiliary pathologies. Finally, we explore a multidisciplinary approach to acute recurrent and chronic pancreatitis., (Copyright © 2021 Elsevier Inc. All rights reserved.)

Acute pancreatitis (AP) is a serious inflammatory disease with rising incidence both in the adult and pediatric populations. It has been shown that mitochondrial injury and energy depletion are the earliest intracellular events in the early phase of AP. Moreover, it has been revealed that restoration of intracellular ATP level restores cellular functions and defends the cells from death. We have recently shown in a systematic review and meta-analysis that early enteral feeding is beneficial in adults; however, no reviews are available concerning the effect of early enteral feeding in pediatric AP. In this minireview, our aim was to systematically analyse the literature on the treatment of acute pediatric pancreatitis. The preferred reporting items for systematic review (PRISMA-P) were followed, and the question was drafted based on participants, intervention, comparison and outcomes: P: patients under the age of twenty-one suffering from acute pancreatitis; I: early enteral nutrition (per os and nasogastric- or nasojejunal tube started within 48 h); C: nil per os therapy; O: length of hospitalization, need for treatment at an intensive care unit, development of severe AP, lung injury (including lung oedema and pleural effusion), white blood cell count and pain score on admission. Altogether, 632 articles (PubMed: 131; EMBASE: 501) were found. After detailed screening of eligible papers, five of them met inclusion criteria. Only retrospective clinical trials were available. Due to insufficient information from the authors, it was only possible to address length of hospitalization as an outcome of the study. Our mini-meta-analysis showed that early enteral nutrition significantly (SD = 0.806, P = 0.034) decreases length of hospitalization compared with nil per os diet in acute pediatric pancreatitis. In this minireview, we clearly show that early enteral nutrition, started within 24-48 h, is beneficial in acute pediatric pancreatitis. Prospective studies and better presentation of research are crucially needed to achieve a higher level of evidence., Competing Interests: Conflict-of-interest statement: All the authors disclaim any form of conflict of interest.

Background/objectives: Approximately 15-20% of pediatric patients with acute pancreatitis (AP) develop severe disease. Severity scoring tools were developed for adult patients, but have limitations when applied in children. We aimed to identify early predictors of severe acute pancreatitis (SAP) on hospital admission for early risk stratification of patients., Methods: Retrospective review of AP admissions was conducted.

Abstract: Ectopic pancreas is defined by the presence of abnormally situated pancreatic tissue that lacks contact with normal pancreas and possesses its own duct system and vascular supply. Ectopic pancreas in the gastrointestinal tract is not uncommon. Moreover, there are several reported cases of adult ectopic pancreatitis in the literature, but to date, only two cases of pediatric ectopic pancreatitis have been reported. We describe a 15-year-old female with acute right upper quadrant pain and elevated serum lipase and amylase, in whom the radiological diagnosis was mesenteric soft tissue mass with adjacent inflammatory changes. The surgical pathology diagnosis, however, was mesenteric ectopic pancreas complicated by pancreatitis. We advocate for ectopic pancreatitis to be considered in a pediatric patient with acute abdominal pain, laboratory findings consistent with pancreatitis, and imaging findings of a mesenteric mass and normal orthotopic pancreas.

Pediatric pancreatitis is a rare disease with variable etiology. In the past 10-15 years the incidence of pediatric pancreatitis has been increased. The management of pediatric pancreatitis requires up-to-date and evidence based management guidelines. The Hungarian Pancreatic Study Group proposed to prepare an evidence based guideline based on the available international guidelines and evidences. The preparatory and consultation task force appointed by the Hungarian Pancreatic Study Group translated and complemented and/or modified the international guidelines if it was necessary. In 8 clinical topics (diagnosis; etiology; prognosis; imaging; therapy; biliary tract management; complications; chronic pancreatitis) 50 relevant questions were defined. Evidence was classified according to the UpToDate(®) grading system. The draft of the guidelines was presented and discussed at the consensus meeting on September 12, 2014. All clinical statements were accepted with total (more than 95%) agreement. The present Hungarian Pancreatic Study Group guideline is the first evidence based pediatric pancreatitis guideline in Hungary. The present guideline is the first evidence-based pancreatic cancer guideline in Hungary that provides a solid ground for teaching purposes, offers quick reference for daily patient care in pediatric pancreatitis and guides financing options. The authors strongly believe that these guidelines will become a standard reference for pancreatic cancer treatment in Hungary.
