Acute pancreatitis in children: spectrum of disease and predictors of severity

Acute Pancreatitis in Children: It's Not Just a Simple Attack

Acute pancreatitis (AP) in children presents unique challenges distinct from adult manifestations, requiring specialized diagnostic and therapeutic approaches. Compared with adults, pediatric AP has lower mortality rates but still carries significant morbidity and potential long-term complications. This review examines current evidence on pediatric AP, highlighting recent advances in diagnosis, risk stratification, and management strategies. Current diagnostic approaches use serum lipase and amylase testing, along with various imaging modalities that have different diagnostic values. Recent research has identified promising biomarkers for predicting severe AP, including blood urea nitrogen, C-reactive protein, and specific cytokine signals. Emerging evidence suggests a role of gut microbiome dysbiosis in disease pathogenesis, opening new therapeutic possibilities targeting the gut-pancreas axis. Genetic factors, specifically pancreatitis risk genes, influence disease progression to recurrent and chronic pancreatitis. In this review, we summarize the consequences of an isolated AP episode in children. Our review highlights for the first time how AP can lead to significant long-term sequelae, including exocrine/nutritional deficiencies, endocrine pancreatic dysfunction, diabetes, recurrent pain, and decreased quality of life compared with healthy population controls. The goal of this review is to summarize advances in understanding of pediatric AP and to emphasize the importance of early recognition, appropriate risk stratification, and comprehensive follow-up after the first pediatric AP episode, while highlighting areas requiring future research to optimize patient outcomes.

Computed Tomography Assessment of Severity of Acute Pancreatitis in Bangladeshi Children

Purpose

Acute pancreatitis (AP) is common among children in Bangladesh. Its management depends mainly on risk stratification. This study aimed to assess the severity of pediatric AP using computed tomography (CT).

Methods

This cross-sectional, descriptive study was conducted in pediatric patients with AP at the Department of Pediatric Gastroenterology and Nutrition, BSMMU, Dhaka, Bangladesh.

Results

Altogether, 25 patients with AP were included, of whom 18 (mean age, 10.27±4.0 years) were diagnosed with mild AP, and 7 (mean age, 10.54±4.0 years) with severe AP. Abdominal pain was present in all the patients, and vomiting was present in 88% of the patients. Etiology was not determined. No significant differences in serum lipase, serum amylase, BUN, and CRP levels were observed between the mild and severe AP groups. Total and platelet counts as well as hemoglobin, hematocrit, serum creatinine, random blood sugar, and serum alanine aminotransferase levels (p>0.05) were significantly higher in the mild AP group than in the severe AP group (p=0.001). The sensitivity, specificity, positive predictive value, and negative predictive value of CT severity index (CTSI) were 71.4%, 72.2%, 50%, and 86.7%, respectively. In addition, significant differences in pancreatic appearance and necrosis were observed between the two groups on CT.

Conclusion

CT can be used to assess the severity of AP. In the present study, the CTSI effectively assessed the severity of AP in pediatric patients.

The Potential Role of Model for End-Stage Liver Disease (MELD)-Sodium Score in Predicting the Severity of Acute Pancreatitis

Background and aim Acute pancreatitis is a common inflammation of the pancreas which can be severe and even potentially mortal. High rates of mortality showed the importance of immediate identification of patients at high risk and led the clinicians to refer to various scoring systems. Our aim was to investigate a clinical predictive model using the Model for End-Stage Liver Disease-Sodium (MELD-sodium) scoring system, adapting it to acute pancreatitis patients referring to the systemic inflammatory nature of the disease and potential multi-organ failures in severe form. Methods Our multicenter study was designed retrospectively. The medical records were reviewed for the period of two years. Demographics, biochemical results, MELD-sodium scores and mortality rates were analysed. Results MELD-sodium score was found to be statistically correlated with both mortality and the severity of pancreatitis (p<0.001) and significant difference between both mild and severe (p<0.001), moderate and severe groups (p<0.001). Mortality was found to be significantly higher in patients with MELD-Na score when the cut-off value was accepted as '≥11'. Conclusion We found that MELD-sodium score was significantly associated with both severity of disease and mortality rates and also significantly effective between both mild/severe and moderate/severe groups which may be a guide for future multi-center reviews with larger patient and control groups, which can define the potential role of this non-invasive and easy-to-use predictive model in acute pancreatitis patients.

[Prevention and management of pegaspargase associated-toxicities (excluding coagulation abnormalities). Recommendations of the French Society of Children and Adolescent Cancers (Leukemia committee)]

Pegaspargase (Oncaspar®), a pegylated form of native Escherichia Coli-derived L-asparaginase is an essential component chemotherapy used in the treatment of acute lymphoblastic leukemia (ALL) in pediatric and adult patients. Its particular toxicity profile requires a specific management to improve safety and tolerability and optimize treatment outcome and therefore survival. Within the framework of workshops of practice harmonization of the French Society of Children and Adolescent Cancers, diagnostic and management of the most commonly occuring toxicities (excluding coagulation abnormalities) during Pegaspargase treatment were reviewed according to the analysis of published studies.

The course of acute pancreatitis in children and potential simple laboratory markers of severity - a single centre retrospective study

AIM

To evaluate the usefulness of routinely measured biochemical and complete blood count parameters as potential markers of the severity of pediatric acute pancreatitis.

METHODS

The retrospective study included children with acute pancreatitis hospitalised over a 3-year period. Demographic, clinical and laboratory data were collected.

RESULTS

55 patients were enrolled in the study. Mild acute pancreatitis was diagnosed in 45 children (82%), moderately severe in 7 (13%), and severe in 3 patients (5%). Together 10 children (18%) were categorized into a single severe group. Children with severe acute pancreatitis had higher white blood cell and platelet counts on admission as well as a C-reactive protein concentration after 48 hours. The C-reactive protein concentration after 48 hours (cut-off: 127,2 mg/l) and the white blood cell count on admission (cut-off: 13,5x10³ /μl) were found to be statistically significant markers in predicting the severity of the disease. The C-reactive protein concentration after 48 hours was demonstrated as an independent predictor.

CONCLUSION

Severe acute pancreatitis is observed in a quite significant percentage of children. The white blood cell count on admission and the C-reactive protein concentration after 48 hours (as an independent predictor) may be potential simple laboratory markers of the severity of the disease.

Acute Pancreatitis in Childhood: A 10-Year Experience From A Thai University Surgical Center

OBJECTIVES

This study aimed to describe etiology, management, and health outcomes of children developing acute pancreatitis at a tertiary Thailand pediatric surgery center.

METHODS

Medical case records of all index cases during 2006-2016 were analyzed and reported.

RESULTS

There were 42 male and 37 female patients, with a mean (standard deviation) age of 10.4 (4.5) years, included in the study. Medications were the commonest etiology for 39.3% of acute pancreatitis attacks, 11.4% for biliary tract disease cases, and 8% for postinterventional studies. In 30% of cases, no cause(s) was defined. Sixty-two patients (78.5%) had elevated serum lipase on hospital admission, whereas only 30.4% showed a raised amylase. Hospital stay was 15 days (interquartile range, 6-27 days). Two major complications in the series were pseudocysts (8.8%) and necrotizing pancreatitis (7.6%). Etiological factors and/or antibiotics were not directly linked to any specific complications. Seventeen children (22.8%) had 1 recurrent episode of acute pancreatitis documented. Mortality rate in index cases was 28%, with a higher percentage harboring a preexisting illness (34.4% vs 5.6%; P = 0.01) and in male than in female patients (41% vs 14%; P = 0.01).

CONCLUSIONS

Deaths from pediatric acute pancreatitis are more prevalent in male individuals and those with a preexisting illness. Targeted strategies aimed at "highest-risk" patients may potentially offset mortality.

Acute Pancreatitis and Recurrent Acute Pancreatitis in Children: A 10-Year Retrospective Study

Aim

To compare the clinical characteristics of acute pancreatitis (AP) and recurrent acute pancreatitis (ARP) in children.

Method

From January 2011 to January 2021, a total of 275 pediatric patients with AP admitted to a tertiary teaching hospital were enrolled.

Results

The median age of 275 children was 12.0 years. Among them, 55 cases were ARP. The leading causes of pediatric pancreatitis were biliary tract and virus infection. The percent of male in the AP group was higher than that in the ARP group. Viral infection in the AP group were higher than that in the ARP group, but anatomical abnormalities were lower than those in the ARP group. The incidence of pancreatic pseudocysts in the ARP group was higher than that in the AP group. The median interval time from AP to ARP was 3.0 months.

Conclusion

The main causes of pediatric pancreatitis were biliary tract and virus infection in the study. AP caused by virus infection seems to be less likely to develop into ARP. Female and anatomical abnormality are risks of ARP. Children with ARP are more likely to be complicated with pancreatic pseudocyst. There was no difference in ICU admission or mortality between AP and ARP.

Etiology and classification of acute pancreatitis in children admitted to ICU using the Pediatric Sequential Organ Failure Assessment (pSOFA) score

BACKGROUND

Pediatric acute pancreatitis (AP) is rare but increasing. Severe AP is associated with higher morbidity and mortality. However, there are no universally accepted prognostic criteria for AP.

METHODS

This retrospective study included children with AP admitted to an intensive care unit (ICU) of our tertiary pediatric center between January 2009 and December 2018. The severity of organ dysfunction in AP was assessed according to the modified Atlanta criteria using the Pediatric Sequential Organ Failure Assessment (pSOFA) and Computed Tomography Severity Index (CTSI).

RESULTS

Seventy acute episodes of AP were evaluated in 55 children with primary pancreatitis. In addition, secondary AP was diagnosed in 15 patients originally admitted to ICU for different indications. Mild AP [no organ dysfunction, normal computed tomography (CT) finding] was the most prevalent (64/85 episodes in 49 children), followed by moderate AP (15 children; pSOFA 2-9 points, CTSI 3-4 points on admission). Severe AP (pSOFA 4-17 points, CTSI 6-10 points) was diagnosed in 6 children with traumatic or secondary AP. The most frequent etiologies of primary AP episodes were idiopathic (39%) and biliary (31%). Children with idiopathic AP had frequent relapses and comorbidities. Hereditary AP was typically mild, but presented with high pancreatic enzyme levels and recurrence rates. Admission at ICU and an interval without enteral nutrition (EN) were relatively short in drug-induced AP and relatively long in secondary and traumatic AP. Endoscopic retrograde cholangiopancreatography (ERCP) was performed in 13 patients with biliary AP and in 4 patients with traumatic AP. No AP-related death was observed.

CONCLUSION

pSOFA score accurately reflects the severity and prognosis of AP in children.

C-reactive protein accurately predicts severity of acute pancreatitis in children

INTRODUCTION

Predicting severity of acute pancreatitis enables optimization of care, reducing morbidity and length of stay. Modified adult scoring systems have not been able to adequately predict severity in children.

METHODS

This was a retrospective study of children presenting with a first episode of acute pancreatitis from 2002 to 2020 in a single tertiary paediatric surgical centre. Serum markers including CRP at 48 h of admission were analysed. Promising biomarkers underwent ROC (Receiver Operating Curve) analysis, and these were compared to the modified Glasgow Pancreas Score. An AUC (Area Under Curve) > 0.90 was taken as an excellent predictor of severity.

RESULTS

Data of 59 children were analysed, median age 13 years. 22 patients (37%) had a severe episode. ROC analysis demonstrated CRP as the best predictor of severity giving an AUC of 0.92. Optimum cut off value for CRP was 107.5 mg/L (p < 0.0001) producing sensitivity of 91%, specificity of 84%. This was superior to the modified Glasgow Pancreas score, which produced a sensitivity of 36% and specificity of 100%.

CONCLUSION

We have shown that a CRP value of > 108 mg/L within 48 h of admission can be used to predict severity of acute pancreatitis in children with greater accuracy than current scoring systems.

Acute Pancreatitis and Prognosticating Its Severity in Young Adults: A Case Report

Acute pancreatitis develops into mild acute, moderately severe, and severe forms in multiple clinical scenarios. The severity assessment of pancreatitis relies on various scoring systems, including CT Severity Index (CTSI), Multiple Organ Dysfunction Syndrome (MODS), Acute Physiology and Chronic Health Evaluation II (APACHE-II), Bedside Index for Severity in Acute Pancreatitis (BISAP), Systemic Inflammatory Response Syndrome (SIRS), Multiple Organ System Score (MOSS), Glasgow score, and Ranson's Criteria (RC). This case report corresponds to a 20-year-old male with acute pancreatitis of unknown etiology. The RC scoring method produced two points, which could not prognosticate the possible severity of acute pancreatitis in the young patient. The hospital course included intubation with mechanical ventilation and ICU management. 

Matrix metalloproteinases and their inhibitors in pediatric severe acute pancreatitis

BACKGROUND

Acute pancreatitis (AP) is increasing in incidence in adult and pediatric patients. Identification of patients at high risk for progression to severe acute pancreatitis (SAP) is crucial, as it can lead to increased mortality and health system cost. Matrix metalloproteinases (MMPs) are endopeptidases which degrade extracellular matrix proteins and increase activity of pro-inflammatory cytokines. Tissue inhibitors of metalloproteinases (TIMPs) regulate MMP activity. Prior limited studies of MMPs and TIMPs have found some to be associated with development of SAP. The aim of this study was to further investigate the role of MMPs and TIMPs in detecting pediatric patients at risk for developing moderately severe AP or SAP.

METHODS

Plasma samples were prospectively collected for patients <21 years of age presenting with AP between November 2015 and October 2019, along with healthy controls. Bead-based multiplex assays were utilized to test levels of 12 MMPs and TIMPs.

RESULTS

Samples were collected from 7 subjects who developed SAP, 7 with moderately severe AP, 45 with mild AP and 44 healthy controls. MMP-9 (p = 0.04) and TIMP-1 (p = 0.01) levels were significantly higher in SAP patients. A multivariable logistic regression model using MMP-9 and TIMP-1 predicted SAP (AUROC 0.87, 95% CI 0.76-0.98).

CONCLUSION

We have demonstrated that MMP9 and TIMP1 levels are increased at AP presentation in pediatric patients who developed SAP during the course of illness. Further studies are needed to validate the use of MMPs and TIMPs as predictive tools for development of SAP in pediatric pancreatitis.

A Practical Approach to Management of Acute Pancreatitis: Similarities and Dissimilarities of Disease in Children and Adults

Acute pancreatitis (AP) is associated with significant morbidity and mortality, and it substantially contributes to the healthcare burden of gastrointestinal disease and quality of life in children and adults. AP across the lifespan is characterized by similarities and differences in epidemiology, diagnostic modality, etiologies, management, adverse events, long-term outcomes, and areas in greatest need of research. In this review, we touch on each of these shared and distinctive features of AP in children and adults, with an emphasis on recent advances in the conceptualization and management of AP.

Pediatric Acute Pancreatitis: Changes in Management and Disease Outcomes Over 16 Years

OBJECTIVE

To examine the changes over time of pediatric acute pancreatitis (AP) severity, management, and disease outcomes at our academic tertiary center.

METHODS

We reviewed 223 pediatric AP admissions (2002-2018) and used a time-to-event regression model to study changes over time. Disease outcomes were analyzed using a subgroup of 89 patients in whom only the AP event determined length of hospital stay and duration of opioid use.

RESULTS

There was an increase in mild, but not severe, AP episodes over the examined period. June 2014 was identified as a single cutoff point for change in AP management and disease outcomes independent of each other and of disease severity. Timing of initiating enteral nutrition decreased from 5 to 1.6 days (P < 0.0001) in the entire cohort and from 4.1 to 1.8 days in the subgroup (P = 0.0001) after June 2014. Length of hospitalization decreased from 6 to 3.3 days (P = 0.0008) and days of opioid use from 4.1 to 1.3 (P = 0.002) after June 2014.

CONCLUSIONS

Timing of initiating enteral nutrition has significantly reduced at our center after June 2014. In parallel, we observed a significant improvement in disease outcomes.

North American Society for Pediatric Gastroenterology, Hepatology and Nutrition and the Society for Pediatric Radiology Joint Position Paper on Noninvasive Imaging of Pediatric Pancreatitis: Literature Summary and Recommendations

ABSTRACT

The reported incidence of pediatric pancreatitis is increasing. Noninvasive imaging, including ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI), play important roles in the diagnosis, staging, follow-up, and management of pancreatitis in children. In this position paper, generated by members of the Pancreas Committee of the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) and the Abdominal Imaging Committee of The Society for Pediatric Radiology (SPR), we review the roles of noninvasive imaging in pediatric acute, acute recurrent, and chronic pancreatitis. We discuss available evidence related to noninvasive imaging, highlighting evidence specific to pediatric populations, and we make joint recommendations for use of noninvasive imaging. Further, we highlight the need for research to define the performance and role of noninvasive imaging in pediatric pancreatitis.

Undernutrition and Obesity Are Associated with Adverse Clinical Outcomes in Hospitalized Children and Adolescents with Acute Pancreatitis

Background: Adult studies demonstrated that extremes of nutritional status adversely impact clinical outcomes in acute pancreatitis (AP). With rising prevalence of undernutrition/obesity in children, we analyzed the effect of nutritional status on the clinical outcomes in children and adolescents with acute pancreatitis. Methodology: We analyzed the Kids' Inpatient Database (KID) between 2003 and 2016 to include all patients with a primary diagnosis of AP using specific International Classification of Diseases (ICD) codes. We classified into (1) undernutrition, (2) obesity and (3) control groups, based on ICD codes, and we compared severe acute pancreatitis and healthcare utilization (length of stay and hospitalization costs). Results: Total number of AP admissions was 39,805. The prevalence of severe AP was higher in the undernutrition and obesity groups than the control group (15.7% vs. 5.8% vs. 3.5% respectively, p < 0.001). Multivariate analyses demonstrated that undernutrition and obesity were associated with 2.5 and 1.6 times increased risk of severe AP, p < 0.001. Undernutrition was associated with an additional six days of hospitalization and almost $16,000 in hospitalization costs. Obesity was associated with an additional 0.5 day and almost $2000 in hospitalization costs, p < 0.001. Conclusion: Undernutrition and obesity were associated with greater severity of AP, as well as prolonged hospitalization stay and costs. It is imperative for treating clinicians to be aware of these high-risk groups to tailor management and strive for improved outcomes.

Who's at Risk? A Prognostic Model for Severity Prediction in Pediatric Acute Pancreatitis

OBJECTIVES

The aim of the study was to validate and optimize a severity prediction model for acute pancreatitis (AP) and to examine blood urea nitrogen (BUN) level changes from admission as a severity predictor.

STUDY DESIGN

Patients from 2 hospitals were included for the validation model (Children's Hospital of the King's Daughters and Children's National Hospital). Children's Hospital of the King's Daughters and Cincinnati Children's Hospital Medical Center data were used for analysis of BUN at 24 to 48 hours.

RESULTS

The validation cohort included 73 patients; 22 (30%) with either severe or moderately severe AP, combined into the all severe AP (SAP) group. Patients with SAP had higher BUN (P = 0.002) and lower albumin (P = 0.005). Admission BUN was confirmed as a significant predictor (P = 0.005) of SAP (area under the receiver operating characteristic [AUROC] 0.73, 95% confidence interval [CI] 0.60-0.86). Combining BUN (P = 0.005) and albumin (P = 0.004) resulted in better prediction for SAP (AUROC 0.83, 95% CI 0.72-0.94). A total of 176 AP patients were analyzed at 24-48 hours; 39 (22%) met criteria for SAP. Patients who developed SAP had a significantly higher BUN (P < 0.001) after 24 hours. Elevated BUN levels within 24 to 48 hours were independently predictive of developing SAP (AUROC: 0.76, 95% CI: 0.66-0.85). Patients who developed SAP had a significantly smaller percentage decrease in BUN from admission to 24 to 48 hours (P = 0.002).

CONCLUSION

We externally validated the prior model with admission BUN levels and further optimized it by incorporating albumin. We also found that persistent elevation of BUN is associated with development of SAP. Our model can be used to risk stratify patients with AP on admission and again at 24 to 48 hours.

Drug induced pancreatitis is the leading known cause of first attack acute pancreatitis in children

BACKGROUND/OBJECTIVES

Drug induced acute pancreatitis (DIAP) as one of the acute pancreatitis (AP) risks factors is a poorly understood entity. The aim of the current study was to compare the characteristics and course of DIAP cases in children presenting with a first attack of AP.

METHODS

Patients presenting with AP were included in a prospective database. We enrolled 165 AP patients that met criteria for inclusion. DIAP patients were included in that group if they were exposed to a drug known to be associated with AP and the rest were included in the non-drug induced-acute pancreatitis (non-DIAP) group.

RESULTS

DIAP was observed in 40/165 (24%) of cases, 24 cases had drug-induced as the sole risk factor, and 16 had DIAP with another risk factor(s). The two groups were similar in intravenous fluid and feeding managements, but ERCP was more commonly performed in the non- DIAP group, 14 (11%), vs 0% in the DIAP group, p = 0.02. Moderately severe [9 (23%) vs 11 (9%)] and severe AP [7 (18%) vs 6 (5%)] were more commonly associated with DIAP than non- DIAP, p = 0.001. DIAP was more commonly associated with ICU stay, 10 (25%), vs 12 (10%), p = 0.01, hospital stay was longer in DIAP median (IQR) of 6 (3.9-11) days vs 3.3 (2-5.7) days in non- DIAP, p = 0.001. The DIAP group had a significantly higher proportion of comorbidities (p < 0.0001).

CONCLUSIONS

DIAP is a leading risk factor for a first attack of AP in children and is associated with increased morbidity and severity of the pancreatitis course. DIAP warrants further investigation in future studies.

Acute pancreatitis in children: Updates in epidemiology, diagnosis and management

Acute pancreatitis (AP), manifesting as acute onset of abdominal pain, vomiting, and nausea, is increasingly being recognized in children secondary to increased awareness, more identifiable etiologies as well as advances in diagnostic capabilities, like imaging. Despite this increased awareness and ability for more frequent diagnoses, the natural history of AP remains poorly understood leading to gaps in approach and management, especially in children. Coupled with poor epidemiologic and management awareness, there remains a lack of understanding of the long term implications of severe acute pancreatitis (SAP). Hence, the role of the primary care clinician in the early diagnosis, and management, remains critical and may affect the need for consultation with pediatric sub-specialists like gastroenterologists. This review provides guidelines regarding epidemiology, diagnosis, and management strategies to address some of these gaps.

A single-center analysis of primary nephrotic syndrome with acute pancreatitis in children

Primary nephrotic syndrome (PNS) is one of the most common primary glomerular diseases in children. Patients complicated nephrotic syndrome with pancreatic lesions are rarely reported, and the clinical manifestations in children are atypical. This study has observed the incidence, clinical types, and prognosis of acute pancreatitis (AP) in children with primary nephrotic syndrome, and analyzed its related factors, early diagnosis, and treatment.Seven children with PNS and AP in Shanghai Children's Hospital from January 2015 to December 2017 were reviewed. The clinical data including age, height, weight, body mass index (BMI), diet, biliary tract disease, PNS durations, drugs, proteinuria, creatinine, glucose, glycated hemoglobin, amylase and lipase, albumin, cholesterol, triglyceride, ultrasound, computerized tomography (CT), renal pathology and estimated glomerular filtration rate (eGFR) were retrospectively analyzed. All patients were followed for >2 years.Ten in 589 patients with PNS were detected pancreatic lesions by abdominal ultrasound. Seven were diagnosed as AP, which the incidence was 1.2%. Only 1 of 7 patients had elevated serum amylase. Lesions of pancreas were found by ultrasound and/or enhanced CT. Four of 7 patients had been treated with tacrolimus. All patients with AP were improved after octreotide acetate injection and supportive treatment. Only 1 patient suffered recurrent AP during the relapse of PNS 10 months later.AP in children with PNS is not common, and the clinical manifestations are not typical. Abdominal ultrasound and enhanced CT are of high value in diagnosis. The adverse effects of tacrolimus should be concerned. Early diagnosis and timely treatment can be helpful for a prognosis.

Recent Advances in Diagnosis and Severity Assessment of Acute Pancreatitis

The incidence and prevalence of acute pancreatitis (AP) is increasing over time. The diagnosis of acute pancreatitis is established by revised Atlanta criteria (2012). Multiple criteria and scoring systems have been used for assessment of severity of AP. Majority of acute pancreatitis cases (80%) are mild, the challenge remains in early diagnosis, severity assessment and treatment of severe AP and its complications. Assessment of severity of AP is important part of management because line of treatment depends on aetiology and severity of acute pancreatitis. In this article a comprehensive review of recent advances in diagnosis and severity assessment of acute pancreatitis has been described.

Pancreatitis in pre-adolescent children: a 10 year experience in the pediatric emergency department

Background

The diagnosis of pediatric pancreatitis has been increasing over the last 15 years but the etiology of this is uncertain. The population of pre-adolescent patients with pancreatitis in the emergency department has not been specifically described. Our objective was to determine the characteristics of these patients to illuminate this population and disease in order to better identify them and avoid a delay in diagnosis and treatment.

Methods

This was a retrospective descriptive study of consecutive pediatric patients under the age of 13 years between 2006 and 2016 who presented to our pediatric emergency department with a diagnosis of atraumatic pancreatitis. Patient characteristics, lab and imaging results, identified etiology of pancreatitis, and recurrence rates were recorded and evaluated.

Results

There were 139 visits, of which 85 were for a first episode of acute pancreatitis, and 54 were patients with an episode of recurrent pancreatitis. The median age for all visits was 8 years (IQ range 5–11). Of the acute cases, 26% had uncertain or undetermined etiologies of which half were thought to likely be viral related; 20% had systemic inflammatory or autoimmune diseases; 19% were associated with medications, with the most common being valproic acid; 16% were cholelithiasis-related; and 15% were found to have a genetic, congenital or structural etiology. No patients had elevated triglycerides. Those with cholelithiasis and genetic or structural defects were found to have a higher recurrence rate than those with other etiologies. There were only four patients diagnosed with chronic pancreatitis.

Conclusions

The etiology of pancreatitis in pre-adolescent children has a different distribution than in adolescents and adults, with gallstone disease less frequent and concurrent contributing illness more common. Patients on pancreatitis-causing medications or with known genetic risk or structural pancreatic problems should be tested for pancreatitis if presenting with concerning symptoms. Hypertriglyceridemia and chronic pancreatitis with evidence of pancreatic exocrine insufficiency is uncommon in this population.

Spuriously raised serum amylase in a five-year-old girl: a note of caution in paediatric blood sampling

INTRODUCTION

Capillary (finger prick) blood sampling is commonplace in paediatric practice but this method is prone to produce spurious laboratory results.

CASE PRESENTATION

A five-year-old girl presented with abdominal pain, epigastric tenderness, tachycardia and reduced oxygen saturation. A venous blood sample haemolysed, and serum amylase on a finger prick sample was reported as 2831 units/L. The working diagnosis was acute pancreatitis and respiratory tract infection. A repeat amylase 9 h later was within the normal range. The patient was known to bite her fingers and the possibility of salivary contamination was considered. Serum isoenzyme analysis confirmed presence of high salivary amylase levels with no pancreatic amylase detected. A viral respiratory tract infection and buried gastrostomy bumper were eventually thought to account for the patient's presentation.

CONCLUSION

Increased awareness of the potential for salivary contamination of serum amylase in finger prick samples may prevent misdiagnoses of pancreatitis.

Clinical features of acute pancreatitis in people of different age groups: A retrospective analysis

BACKGROUND

Acute pancreatitis (AP) is one of the common causes of acute abdomen in clinical practice. In the past, patients with AP were mostly young adults. However, in recent years, with the growth and aging of our country's population, the incidence of AP in the elderly and children is also on the rise. The clinical manifestations of AP at different age groups are slightly different due to their physiological characteristics. The clinical manifestations of elderly and children are atypical, which can easily lead to misdiagnosis and missed diagnosis.

AIM

To analyze the clinical features of AP in people of different age groups.

METHODS

In this retrospective clinical trial, 1758 cases of AP were enrolled from January 2003 to June 2016, and they were divided into three groups according to age: <18, 18-60, and ≥ 60 years old. The general clinical data, etiology, severity of AP, complications, clinical course, prognosis, and biochemical criteria for AP were summarized in different age groups.

RESULTS

In the < 18 age group, the incidence of AP in male patients (53.8%) was slightly higher than that of females (46.2%); the proportion of mild AP (MAP) (78.5%) was higher than those the other two groups; and the rates of complications and mortality were significantly lower than those of the other two groups (P < 0.05). In the 18-60 age group, the incidence of AP in male patients (71.0%) was higher than that of the other two groups (P < 0.05); the incidence of alcoholic and hyperlipidemic pancreatitis (13.4%, 21.5%) was higher than that of the other two groups (P < 0.05); the incidence of pancreatic necrosis in this group of patients was the highest (23.4%); and the rates of peripancreatic exudation, pleural effusion, acute respiratory distress syndrome, and acute renal insufficiency (54.3%, 36.9%, 5.6%, and 6.5%, respectively) were significantly higher than those of the < 18 age group (P < 0.05). In the ≥ 60 age group, the incidence of AP in male patients (57.7%) was slightly higher than that in females (42.3%); the rate of nausea (58.2%) was significantly higher than those of the other two groups (P < 0.05); the incidence of biliary pancreatitis (61.2%) was the highest (P < 0.05); and the proportion of patients with moderately severe AP (43.5%) was higher than those of the other two groups (P < 0.05). The patients in the < 18 age group had the longest hospital stay (17.97 ± 12.14 d; P < 0.05). The proportion of patients staying in the intensive care unit and the mortality rate in the ≥ 60 age group were the highest (4.1% and 13.1%, respectively; P < 0.05). There was no difference in hospitalization cost among patients of different age groups (P > 0.05). There was no significant difference in peripheral blood leukocyte count among the three groups (P > 0.05). Mean C-reactive protein level in the < 18 age group was higher than those of the other two groups. Serum amylase was higher in the ≥ 60 age group than in the < 18 age group. Lipase (LPS) in the ≥ 60 age group was higher than those of the other two groups (P < 0.05), and mean LPS did not differ significantly between the18-60 and < 18 age groups (P > 0.05).

CONCLUSION

The incidence of alcoholic and hyperlipidemic pancreatitis is higher in middle-aged people. Elderly patients with AP are most prone to nausea, and the mortality rate is the highest. When young people have unexplained vomiting and bloating, AP should be suspected.

Pancreatitis in Children

Acute, acute recurrent, and chronic forms of pancreatitis have been increasingly diagnosed in children in the past 2 decades. Risk factors in the pediatric group are broad and appear to be strikingly different compared with the adult cohort. However, the disease burden and impact on quality of life are surprisingly similar in children and adults. This review summarizes the definitions, epidemiology, risk factors, diagnosis, and management of pediatric pancreatitis, identifies features that are unique to the childhood-onset disease, identifies gaps, and proposes recommendations for future opportunities.

Young Age Predicts Acute Pancreatitis Severity in Children

OBJECTIVES

The course and evolution of pediatric acute pancreatitis (AP) is poorly understood. Prognostication models in children perform poorly and lack consensus. We aimed to identify predictors of AP severity, and the risk for AP recurrence.

METHODS

We retrospectively studied all patients hospitalized with AP at a single tertiary center, between January 1995 and June 2016. Patient demographics and admission laboratory data were assessed for severity and recurrence prediction.

RESULTS

A total of 68 patients accounting for a total of 117 (15 moderate-severe) AP episodes were reviewed. Patients with moderate-severe disease were significantly younger (median [interquartile range (IQR)] of 8.3 [4.0-14.4] vs 13.8 [8.1-16.0] years, P = 0.02). Young age at presentation was associated with odds ratio of 3.8 (confidence interval [CI] 1.2-12.1) for children younger than 12 years and 5.8 (CI 1.6-21.4) for children younger than 6 years for developing moderate-severe disease.Further subanalysis of the 59 patients with first-time AP episodes, demonstrated younger age (median [IQR] of 5.3 [2.9-10.4] vs 12.0 [6.3-15.8] years, P = 0.03) and elevated white blood cell count (median [IQR] of 22.8 [11.8-31.3] vs 11.0 [8.1-14.6] 10/L, P < 0.01) of patients with moderate-severe disease, conferring a risk for moderate-severe disease with odds ratio of 7.5 (CI 1.5-38.2) for children younger than 6 years and 5.3 (CI 1.1-25.4) for patients with white blood cell count >15 × 10/L, respectively. Fourteen (23.7%) of 59 patients with first-time episodes had recurrent AP. Analysis of the data at the primary episode failed to identify predictors to indicate future recurrence.

CONCLUSIONS

In our cohort, only young age (<12 years) predicted AP severity. No parameters were identified to predict future development of AP recurrence.

Aging and Comorbidities in Acute Pancreatitis I: A Meta-Analysis and Systematic Review Based on 194,702 Patients

Background: Acute pancreatitis (AP) is one of the most common cause of hospitalization among gastrointestinal diseases worldwide. Although most of the cases are mild, approximately 10-20% of patients develop a severe course of disease with higher mortality rate. Scoring systems consider age as a risk factor of mortality and severity (BISAP; >60 years, JPN>70 years, RANSON; >55 years, APACHE II >45 years). If there is a correlation between aging and the clinical features of AP, how does age influence mortality and severity? Aim: This study aimed to systematically review the effects of aging on AP. Methods: A comprehensive systematic literature search was conducted in the Embase, Cochrane, and Pubmed databases. A meta-analysis was performed using the preferred reporting items for systematic review and meta-analysis statement (PRISMA). A total of 1,100 articles were found. After removing duplicates and articles containing insufficient or irrelevant data, 33 publications involving 194,702 AP patients were analyzed. Seven age categories were determined and several mathematical models, including conventional mathematical methods (linear regression), meta-analyses (random effect model and heterogeneity tests), meta-regression, funnel plot and Egger's test for publication bias were performed. Quality assessment was conducted using the modified Newcastle-Ottawa scale. The meta-analysis was registered in the PROSPERO database (CRD42017079253). Results: Aging greatly influences the outcome of AP. There was a low severe AP incidence in patients under 30 (1.6%); however, the incidence of severe AP showed a continuous, linear increase between 20 and 70 (0.193%/year) of up to 9.6%. The mortality rate was 0.9% in patients under 20 and demonstrated a continuous linear elevation until 59, however from this age the mortality rate started elevating with 9 times higher rate until the age of 70. The mortality rate between 20 and 59 grew 0.086%/year and 0.765%/year between 59 and 70. Overall, patients above 70 had a 19 times higher mortality rate than patients under 20. The mortality rate rising with age was confirmed by meta-regression (coefficient: 0.037 CI: 0.006-0.068, p = 0.022; adjusted r2: 13.8%), and severity also (coefficient: 0.035 CI: 0.019-0.052, p < 0.001; adjusted r2: 31.6%). Conclusion: Our analysis shows a likelihood of severe pancreatitis, as well as, pancreatitis-associated mortality is more common with advanced age. Importantly, the rapid elevation of mortality above the age of 59 suggests the involvement of additional deteriorating factors such as co-morbidity in elderly.

Blood Urea Nitrogen Elevation Is a Marker for Pediatric Severe Acute Pancreatitis

OBJECTIVE

The natural course of patients who develop acute pancreatitis (AP) can range from mild to severe acute pancreatitis (SAP). The aim of this study was to evaluate for early predictors of developing SAP during the first episode of AP in a prospective pediatric cohort.

METHODS

Clinical data were prospectively collected and subsequently analyzed for pediatric patients presenting with their first episode of AP between March 2013 and January 2017 to Cincinnati Children's Hospital Medical Center.

RESULTS

A total of 118 patients were included in the analysis, and 22 (18.6%) developed SAP. Patients who developed SAP had significantly higher values of blood urea nitrogen (BUN) (P = 0.007), magnesium (P = 0.04), glucose (P = 0.03), sodium (P = 0.03), and C-reactive protein (P = 0.02). A logistic regression model with BUN as a predictor of SAP was superior to any other combination of variables (area under the receiver operating characteristic curve, 0.75; 95% confidence interval, 0.61-0.89; sensitivity, 63%; specificity, 81%; positive predictive value, 43%; negative predictive value, 91%).

CONCLUSIONS

This study generated a predictive model using elevated BUN as a significant predictor of SAP. The findings are useful for early identification of pediatric patients at higher risk of developing SAP.

Validation of Lipase and Systemic Inflammatory Response Syndrome as Prognostic Indicators in Pediatric Acute Pancreatitis: A Retrospective Analysis

INTRODUCTION

Acute pancreatitis (AP) is understudied in the pediatric population despite increasing incidence. Although many cases are mild and resolve with supportive care, severe acute pancreatitis (SAP) can be associated with significant morbidity and mortality. There is a lack of pediatric-specific predictive tools to help stratify risk of SAP in children.

METHODS

A retrospective cohort study of patients with AP or recurrent AP at Cohen Children's Medical Center between 2011 and 2016 was performed. Lipase level and the presence of pediatric systemic inflammatory response syndrome (SIRS) on admission were examined as potential predictors of SAP and length of stay (LOS). A multivariate logistic regression or analysis of covariance was used to conduct the multivariate analysis.

RESULTS

Seventy-nine pediatric patients met inclusion criteria. Approximately 37% (29/79) had SIRS on admission, 22% (17/79) developed SAP, and there were no mortalities. In both the univariate and multivariate models, SIRS was a predictor of SAP. Mean (SD) LOS for patients with SIRS compared with without SIRS was 9.6 ± 8.3 compared with 6.3 ± 6.9 days (P < 0.05). The mean LOS of patients with one or more comorbidity (48%, 38/79) was 10.0 ± 9.5 compared with 5.2 ± 4.0 days (P < 0.01) for those patients without any comorbidities. Only the presence of comorbidities predicted length of time spent nil per os (NPO; P = 0.0022). Patients with comorbidities stayed an average of 5.6 ± 7.6 days NPO, whereas those without comorbidities spent 2.8 ± 2.4 days NPO. Lipase was not predictive of SAP, LOS, or length of time spent NPO.

CONCLUSIONS

These results support the use of SIRS as a simple screening tool on admission to identify children at risk for the development of SAP. The presence of any comorbidity was predictive of LOS and length of NPO in the multivariate model. This may reflect that comorbidities prolong pancreatitis or influence disposition planning.

Concordance of the Balthazar Grade and the Revised Atlanta Classification: Proposing a Modified Balthazar Grade to Predict the Severity of Acute Pancreatitis in Pediatric Population

OBJECTIVES

The aim of this study was to compare the concordance of the Balthazar grade and the revised Atlanta classification and then establish a modified radiological scoring system that would predict 3 degrees of severity of acute pancreatitis (AP) based on the latest Atlanta classification.

METHODS

A retrospective study enrolling pediatric inpatients with AP who had completed computed tomography was conducted between January 2006 and March 2018. The concordance of the 2 radiological scoring systems was assessed with κ statistic.

RESULTS

The Balthazar grade was unable to accurately predict the severity of AP compared with the revised Atlanta classification. However, a modified Balthazar grading system defining patents with Balthazar grades A to C as mild, grade D as moderately, and grade E as severe presented perfect agreement with the revised Atlanta classification across the enrolled population (κ, 0.85; 95% confidence interval, 0.73-0.97). The concordance of the modified Balthazar score and the revised Atlanta classification remained a perfect degree of agreement across repeated tests in 90 random samples (κ, 0.85; 95% confidence interval, 0.85-0.85).

CONCLUSIONS

The modified Balthazar grade demonstrated perfect agreement with the latest Atlanta classification for AP severity scoring. As such, the modified Balthazar grade can be used to predict 3 degrees of severity of AP.

Pancreatic disorders in children: New clues on the horizon

Pancreatic disorders in children represent a growing health problem in pediatric patients. In the past two decades, several advances have been made in the knowledge of pediatric pancreatic disorders, with better understanding of different etiologies and clinical manifestations of these disorders. Moreover, many efforts have been made in pancreatology, aiming to define guidelines in the management of pancreatitis in children, initially based on the available information in adults. A multidisciplinary and multicenter approach is necessary to better determine pancreatic disease pathways and treatment options in children.

Factors Associated With Length of Stay and 30-Day Revisits in Pediatric Acute Pancreatitis

OBJECTIVE

The objective of the study was to identify factors associated with length of stay (LOS) and 30-day hospital revisit for patients hospitalized with acute pancreatitis (AP).

METHOD

Multicenter, retrospective cohort study using the Pediatric Health Information System database. Multilevel linear and logistic regression was used to identify factors independently associated with the primary outcome variables of LOS and 30-day hospital revisit in children aged 1 and 18 years discharged with a primary discharge diagnosis of AP from participating hospitals between 2008 and 2013.

RESULTS

For the 7693 discharges, median LOS was 4 days (interquartile range 3-7 days) and 30-day revisit rate 17.6% (n = 1356). Discharges were primarily girls (55%), Caucasian (46%), and 6 years old or older (85%). On multilevel regression, factors independently associated with both longer LOS and higher revisit odds included malignant and gastrointestinal complex chronic conditions (CCCs) and total parenteral nutrition use while hospitalized. Male gender was associated with both lower LOS (adjusted length of stay = -0.6 days, 95% confidence interval [CI] = -0.8 to -0.4) and decreased revisit odds (aOR 0.85; 95% CI = 0.74 to 0.97). Hispanic ethnicity was associated with increased LOS (adjusted length of stay = +0.8 days, 95% CI = +0.5 to +1.1), but no change in revisit odds.

CONCLUSIONS

Certain demographic and clinical factors, including gender, ethnicity, and type of CCC, were independently associated with LOS and risk of 30-day hospital revisit for pediatric AP. Children with malignant and gastrointestinal CCCs who require total parenteral nutrition are at highest risk for both longer LOS and hospital revisit when admitted with AP. These patient populations may benefit from intensive care coordination when hospitalized for AP.

Utility of CT classifications to predict unfavorable outcomes in children with acute pancreatitis

BACKGROUND

Computed tomography (CT) is useful for the diagnosis of local complications in children with acute pancreatitis but its role as a prognostic tool remains controversial.

OBJECTIVE

To establish the correlation between the CT Severity Index and the Revised Atlanta Classification regarding unfavorable outcomes such as severe acute pancreatitis and need for Pediatric Special Care Unit attention in children with acute pancreatitis.

MATERIALS AND METHODS

We conducted a retrospective and concordance cohort study in which we obtained abdominal CT scans from 30 patients ages 0 to 18 years with acute pancreatitis. Two pediatric radiologists interpreted the results using the CT Severity Index and the Revised Atlanta Classification. The kappa coefficient was determined for each scale. The association among severe acute pancreatitis, need for admission to the Pediatric Special Care Unit and CT systems were established using chi-square or Mann-Whitney U tests. The best CT Severity Index value to predict the need for admission to the Pediatric Special Care Unit was estimated through a receiver operating characteristic (ROC) curve.

RESULTS

Mean CT Severity Index was 5.1±2.8 (mean ± standard deviation on a scale of 0 to 10) for the severe acute pancreatitis group vs. 3.8±2.7 for the mild acute pancreatitis group (P=0.230). The CT Severity Index for the children who were not hospitalized at the Pediatric Special Care Unit was 2.2±2.2 vs. 5.6±2.4 for the group hospitalized at the Pediatric Special Care Unit (P=0.001). Only parenchymal necrosis >30% was associated with severe acute pancreatitis (P=0.021). A CT Severity Index ≥3 has a sensitivity of 89% and specificity of 72% to predict need for admission to the Pediatric Special Care Unit. None of the Revised Atlanta Classification categories was associated with severe acute pancreatitis or admission to the Pediatric Special Care Unit.

CONCLUSION

A CT Severity Index ≥3 in children with acute pancreatitis who require CT assessment based on clinical criteria is associated with the need for admission to the Pediatric Special Care Unit. We found that pancreatic necrosis greater than 30% is the only tomographic parameter related to severe acute pancreatitis. New studies with a greater sample size are necessary to confirm this result.

Multivariate Model for the Prediction of Severity of Acute Pancreatitis in Children

This study aimed to develop a severity prediction system for pediatric patients with acute pancreatitis (AP) based on clinical and laboratory parameters recorded at disease onset. A retrospective cohort study including 130 patients with AP, aged 0 to 18 years, was conducted. Correlations between severe AP (SAP) and clinical and laboratory data were established. Parameters with a significant statistical correlation (P ≤ 0.05) were incorporated in logistic regression models, and receiver operating characteristic curves were generated. The best-performance cutoff points were calculated to propose a severity prediction score, for which sensitivity and specificity were determined. Thirty-eight cases (29.2%) were consistent with SAP. A value of ≥1 point yielded a sensitivity of 81.5% and specificity of 64.1% for SAP prediction, when using a score including blood urea nitrogen ≥12.5 mg/dL (1 point) or hemoglobin <13 mg/dL (1 point) as variables. The proposed severity score showed good performance in predicting SAP.

Acute Pancreatitis Admission Trends: A National Estimate through the Kids' Inpatient Database

OBJECTIVES

To evaluate national health care use and costs for pediatric acute pancreatitis.

STUDY DESIGN

The Kids' Inpatient Database for 2006, 2009, and 2012 was queried for patients with a principal diagnosis of acute pancreatitis. Cases were grouped by age: preschool (<5 years of age), school age (5-14 years of age), and adolescents (>14 years of age).

RESULTS

A total of 27 983 discharges for acute pancreatitis were found. The number of admissions increased with age: young n = 1279, middle n = 8012, and older n = 18 692. Duration of stay was highest in preschool children (median, 3.47 days; IQR, 2.01-7.35), compared with school age (median, 3.22 days; IQR, 1.81-5.63) and adolescents (median, 2.87 days; IQR, 1.61-4.81; P < .001). The median cost of hospitalization varied with age: $6726 for preschoolers, $5400 for school-aged children, and $5889 for adolescents (P < .001). Acute pancreatitis-associated diagnoses varied by age. The presence of gallstone pancreatitis, alcohol, and hypertriglyceridemia was more common among older children compared with younger children (P < .001). There was an increasing trend in acute pancreatitis, chronic pancreatitis, and obesity for the 2 older age groups (P < .001).

CONCLUSION

Admission of children for acute pancreatitis constitutes a significant healthcare burden, with a rising number of admissions with age. However, the cost and duration of stay per admission are highest in young children.

Etiology and clinical characteristics of pediatric acute pancreatitis in Saudi Arabia: a 20-year experience from a single tertiary center

Background

Cases of acute pancreatitis (AP) have increased among pediatric populations worldwide; however, the natural course of this condition in Saudi Arabia was unknown.

Aim

To report the characteristics as well as outcomes of pediatric AP.

Patients and methods

A retrospective chart review study was conducted to include acute pancreatitis in patients ≤ 19 years. The period was from 1994 until 2015. Demographic, clinical, laboratory, imaging and outcome data were collected and analyzed.

Results

50 patients (n = 26; 52% males vs. n = 24; 48% females) were included. The mean age at diagnosis was 11.6 years. The mean length of hospital stay was 10.5 days. 9 (18%) patients had a recurrence of AP and 4 (8%) had complications. Idiopathic AP was the most frequent etiology (n = 21; 42%), followed by cholelithiasis (n = 11; 22%). 2 patients (4%) had drug-induced AP, where one was taking isoniazid and the other had taken a large amount of erythromycin, amoxicillin and ibuprofen. 2 choledochal cysts complicated by AP (4%). Pancreaticobiliary diseases, as a complete entity, accounted for 34% (n = 17). Clinically, abdominal pain (n = 47; 94%) and vomiting (n = 38; 76%) were most commonly encountered. KUB was non-diagnostic in all patients. No patient died during their admission.

Conclusion

Although still relatively uncommon in Saudi Arabia, there are on average 2–3 cases of pediatric AP diagnosed annually in our institution. Idiopathic AP was the most common cause. Isoniazid and choledochal cysts are rare causes of AP and were reported in the study.

Accelerating the Drug Delivery Pipeline for Acute and Chronic Pancreatitis: Summary of the Working Group on Drug Development and Trials in Acute Pancreatitis at the National Institute of Diabetes and Digestive and Kidney Diseases Workshop

A workshop was sponsored by the National Institute of Diabetes and Digestive and Kidney Diseases to focus on research gaps and opportunities on drug development for pancreatitis. This conference was held on July 25, 2018, and structured into 3 working groups (WG): acute pancreatitis (AP) WG, recurrent AP WG, and chronic pancreatitis WG. This article reports the outcome of the work accomplished by the AP WG to provide the natural history, epidemiology, and current management of AP; inform about the role of preclinical models in therapy selection; and discuss clinical trial designs with clinical and patient-reported outcomes to test new therapies.

Management of Acute Pancreatitis in the Pediatric Population: A Clinical Report From the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition Pancreas Committee

BACKGROUND

Although the incidence of acute pancreatitis (AP) in children is increasing, management recommendations rely on adult published guidelines. Pediatric-specific recommendations are needed.

METHODS

The North American Society for Pediatric Gastroenterology, Hepatology and Nutrition Pancreas committee performed a MEDLINE review using several preselected key terms relating to management considerations in adult and pediatric AP. The literature was summarized, quality of evidence reviewed, and statements of recommendations developed. The authorship met to discuss the evidence, statements, and voted on recommendations. A consensus of at least 75% was required to approve a recommendation.

RESULTS

The diagnosis of pediatric AP should follow the published INternational Study Group of Pediatric Pancreatitis: In Search for a CuRE definitions (by meeting at least 2 out of 3 criteria: (1) abdominal pain compatible with AP, (2) serum amylase and/or lipase values ≥3 times upper limits of normal, (3) imaging findings consistent with AP). Adequate fluid resuscitation with crystalloid appears key especially within the first 24 hours. Analgesia may include opioid medications when opioid-sparing measures are inadequate. Pulmonary, cardiovascular, and renal status should be closely monitored particularly within the first 48 hours. Enteral nutrition should be started as early as tolerated, whether through oral, gastric, or jejunal route. Little evidence supports the use of prophylactic antibiotics, antioxidants, probiotics, and protease inhibitors. Esophago-gastro-duodenoscopy, endoscopic retrograde cholangiopancreatography, and endoscopic ultrasonography have limited roles in diagnosis and management. Children should be carefully followed for development of early or late complications and recurrent attacks of AP.

CONCLUSIONS

This clinical report represents the first English-language recommendations for the management of pediatric AP. Future aims should include prospective multicenter pediatric studies to further validate these recommendations and optimize care for children with AP.

Increased Burden of Pediatric Acute Pancreatitis on the Health Care System

OBJECTIVES

The incidence of pediatric acute pancreatitis (AP) increased over the past 2 decades and is estimated to be 3 to 13 per 100,000. The impact of rising AP incidence on health care costs is unknown. Our aim was to examine pediatric AP admissions and associated hospital costs in the United States between years 2004 and 2014.

METHODS

Acute pancreatitis admission and cost data were extracted from the Pediatric Health Information System. We determined AP admission and cost percentages each year, as well as the ratio of AP cost to admission percentages to estimate AP "burden." Length of stay, costs of hospitalization, and the effect of intensive care unit care on these estimates were examined.

RESULTS

Between 2004 and 2014, AP admission percentages increased (P = 0.002). Length of stay decreased over time (P < 0.0001) and was longer for those requiring intensive care unit care (P < 0.0001). Acute pancreatitis admissions cost per day significantly increased over time (P < 0.0001). Median AP cost percentage remained 1.2 to 1.7 times higher than AP admission percentage.

CONCLUSIONS

Acute pancreatitis admissions constitute an expensive burden on the health care system relative to the percentage of all admissions. If AP admissions continue to increase, the cost of AP admissions may pose a substantial financial health care burden.

What's unique about acute pancreatitis in children: risk factors, diagnosis and management

Pancreatitis in children is an appreciable problem that has become increasingly prevalent. This Review covers the principles related to the definitions, epidemiology, risk factors, diagnosis and management of acute pancreatitis in children and identifies features that are unique among children. Additionally, knowledge gaps related to management principles are identified.

Classification of Acute Pancreatitis in the Pediatric Population: Clinical Report From the NASPGHAN Pancreas Committee

INTRODUCTION

Acute pancreatitis (AP) is an emerging problem in pediatrics, with most cases resolving spontaneously. Approximately 10% to 30%, however, are believed to develop "severe acute pancreatitis" (SAP).

METHODS

This consensus statement on the classification of AP in pediatrics was developed through a working group that performed an evidence-based search for classification of AP in adult pancreatitis, definitions and criteria of systemic inflammatory response syndrome, and organ failure in pediatrics.

RESULTS AND DISCUSSION

Severity in pediatric AP is classified as mild, moderately severe, or severe. Mild AP is defined by AP without organ failure, local or systemic complications, and usually resolves in the first week. Moderately SAP is defined by the presence of transient organ failure that resolves in no >48 hours, or local complications or exacerbation of co-morbid disease. SAP is defined by persistent organ failure that lasts <48 hours. The presence of systemic inflammatory response syndrome is associated with increased risk for persistent organ dysfunction. Criteria to define organ failure must be pediatric- and age-based.

CONCLUSIONS

Classifying AP in pediatrics in a uniform fashion will help define outcomes and encourage the development of future studies in the field of pediatric pancreatitis.

Incidence and Clinical Associations of Childhood Acute Pancreatitis

OBJECTIVES

To establish the UK incidence and clinical associations of acute pancreatitis (AP) in children aged 0 to 14 years.

METHODS

Monthly surveillance of new cases of AP in children under 15 years of age through the British Pediatric Surveillance Unit conducted from April 2013 to April 2014 (inclusive) followed by 1-year administrative follow-up for all valid cases.

RESULTS

Ninety-four cases (48 boys) fulfilled the diagnostic criteria. The median age at diagnosis was 11.2 years (range 1.3-14.9). White children accounted for 61% of the cases compared with 28% from Asian and 5% from African ethnicities. Pakistani children accounted for 18 of 26 (69%) Asian patients and 19% of the total cohort. The incidence of AP in children in the United Kingdom was 0.78 per 100 000/year (95% confidence interval [CI] 0.62-0.96). The incidence in Pakistani children (4.55; 95% CI 2.60-7.39) was sevenfold greater than white children (0.63; 95% CI 0.47-0.83). Of the 94 cases, 35 (37%) were idiopathic; other associations were: drug therapy, 18 (19%); gallstones, 12 (13%); hereditary, 7 (7%); organic acidemias, 7 (7%); anatomic anomalies, 5 (5%); viral infections, 3 (3%); systemic diseases, 2 (2%); and trauma 1 (1%). The most common drug associations were asparaginase (28%), azathioprine (17%), and sodium valproate (17%).

CONCLUSIONS

Although still relatively uncommon in the United Kingdom, on average there is >1 case of childhood AP diagnosed every week. The associations of AP have changed significantly since the 1970-80s. Overrepresentation of Pakistani children is worthy of further investigation.

Acute Pancreatitis in Pediatric Patients: Demographics, Etiology, and Diagnostic Imaging

OBJECTIVE

The objective of this article is to provide updates on acute pancreatitis in children regarding the imaging findings, causes, and complications based on a review of the current studies in the pediatrics literature. We discuss the epidemiology of acute pancreatitis, the role of imaging and imaging findings in the diagnosis of acute pancreatitis, and the causes and complications of acute pancreatitis.

CONCLUSION

The incidence of acute pancreatitis is increasing in children. Imaging plays an important role in the diagnosis of acute pancreatitis because imaging findings can be used to establish the cause of acute pancreatitis, evaluate for complications of acute pancreatitis, and possibly predict the course of the disease.

Practice recommendations for the monitoring of renal function in pediatric non-renal organ transplant recipients

The management of non-renal pediatric solid organ transplant recipients has become complex over the last decade with innovations in immunosuppression and surgical techniques. Post-transplantation follow-up is essential to ensure that children have functioning allografts for as long as possible. CKD is highly prevalent in these patients, often under recognized, and has a profound impact on patient survival. These practice recommendations focus on the early detection and management of hypertension, proteinuria, and renal dysfunction in non-renal pediatric solid organ transplant recipients. We present seven practice recommendations. Renal function should be monitored regularly in organ transplant recipients, utilizing assessment of serum creatinine and cystatin C. GFR should be calculated using the new Schwartz formula. Transplant physicians should also monitor blood pressure using automated oscillometric devices and confirm repeated abnormal measures with manual blood pressure readings and ambulatory 24-h blood pressure monitoring. Proteinuria and microalbuminuria should also be assessed regularly. Referrals to a pediatric nephrologist should be made for non-renal organ transplant recipients with repeated blood pressures >95th percentile using the Fourth Task Force reference intervals, microalbumin/creatinine ratio >32.5 mg/g (3.7 mg/mmol) creatinine on repeated testing and/or GFR <90 mL/min/1.73 m(2) .
