RESUMEN
INTRODUCTION: Among children who suffer from acute recurrent pancreatitis (ARP) or chronic pancreatitis (CP), acute pancreatitis (AP) episodes are painful, often require hospitalization, and contribute to disease complications and progression. Despite this recognition, there are currently no interventions to prevent AP episodes. In this retrospective cohort study, we assessed the impact of pancreatic enzyme therapy (PERT) use on clinical outcomes among children with pancreatic-sufficient ARP or CP. METHODS: Children with pancreatic-sufficient ARP or CP in the INSPPIRE-2 cohort were included. Clinical outcomes were compared for those receiving vs not receiving PERT, as well as frequency of AP before and after PERT. Logistic regression was used to study the association between development of AP episodes after starting PERT and response predictors. RESULTS: Among 356 pancreatic-sufficient participants, 270 (76%) had ARP, and 60 (17%) received PERT. Among those on PERT, 42% did not have a subsequent AP episode, during a mean 2.1 years of follow-up. Children with a SPINK1 mutation ( P = 0.005) and those with ARP (compared with CP, P = 0.008) were less likely to have an AP episode after starting PERT. After initiation of PERT, the mean AP annual incidence rate decreased from 3.14 down to 0.71 ( P < 0.001). DISCUSSION: In a retrospective analysis, use of PERT was associated with a reduction in the incidence rate of AP among children with pancreatic-sufficient ARP or CP. These results support the need for a clinical trial to evaluate the efficacy of PERT to improve clinical outcomes among children with ARP or CP.
RESUMEN
OBJECTIVES: Drug-associated acute pancreatitis (DAP) studies typically focus on single acute pancreatitis (AP) cases. We aimed to analyze the (1) characteristics, (2) co-risk factors, and (3) reliability of the Naranjo scoring system for DAP using INSPPIRE-2 (the INternational Study group of Pediatric Pancreatitis: In search for a cuRE-2) cohort study of acute recurrent pancreatitis (ARP) and chronic pancreatitis (CP) in children. METHODS: Data were obtained from ARP group with ≥1 episode of DAP and CP group with medication exposure ± DAP. Physicians could report multiple risk factors. Pancreatitis associated with Medication (Med) (ARP+CP) was compared to Non-Medication cases, and ARP-Med vs CP-Med groups. Naranjo score was calculated for each DAP episode. RESULTS: Of 726 children, 392 had ARP and 334 had CP; 51 children (39 ARP and 12 CP) had ≥1 AP associated with a medication; 61% had ≥1 AP without concurrent medication exposure. The Med group had other risk factors present (where tested): 10 of 35 (28.6%) genetic, 1 of 48 (2.1%) autoimmune pancreatitis, 13 of 51 (25.5%) immune-mediated conditions, 11 of 50 (22.0%) obstructive/anatomic, and 28 of 51 (54.9%) systemic risk factors. In Med group, 24 of 51 (47%) had involvement of >1 medication, simultaneously or over different AP episodes. There were 20 ARP and 4 CP cases in "probable" category and 19 ARP and 7 CP in "possible" category by Naranjo scores. CONCLUSIONS: Medications were involved in 51 of 726 (7%) of ARP or CP patients in INSPPIRE-2 cohort; other pancreatitis risk factors were present in most, suggesting a potential additive role of different risks. The Naranjo scoring system failed to identify any cases as "definitive," raising questions about its reliability for DAP.

OBJECTIVES: The objective of this study is to investigate risk factors and disease burden in pediatric acute recurrent pancreatitis (ARP) and chronic pancreatitis (CP). METHODS: Data were obtained from INternational Study group of Pediatric Pancreatitis: In search for a cuRE-2 (INSPPIRE-2), the largest multi-center prospective cohort study in pediatric patients with ARP or CP. RESULTS: Of 689 children, 365 had ARP (53%), 324 had CP (47%). CP was more commonly associated with female sex, younger age at first acute pancreatitis (AP) attack, Asian race, family history of CP, lower BMI%, genetic and obstructive factors, PRSS1 mutations and pancreas divisum. CFTR mutations, toxic-metabolic factors, medication use, hypertriglyceridemia, Crohn disease were more common in children with ARP. Constant or frequent abdominal pain, emergency room (ER) visits, hospitalizations, medical, endoscopic or surgical therapies were significantly more common in CP, episodic pain in ARP. A total of 33.1% of children with CP had exocrine pancreatic insufficiency (EPI), 8.7% had diabetes mellitus. Compared to boys, girls were more likely to report pain impacting socialization and school, medical therapies, cholecystectomy, but no increased opioid use. There was no difference in race, ethnicity, age at first AP episode, age at CP diagnosis, duration of disease, risk factors, prevalence of EPI or diabetes between boys and girls. Multivariate analysis revealed that family history of CP, constant pain, obstructive risk factors were predictors of CP. CONCLUSIONS: Children with family history of CP, constant pain, or obstructive risk factors should raise suspicion for CP.

OBJECTIVES: Abdominal pain, emergency department visits, and hospitalizations impact lives of children with acute recurrent pancreatitis (ARP) and chronic pancreatitis (CP). Data on health-related quality of life (HRQOL) in this population, however, remains limited. We aimed to evaluate HRQOL in children with ARP or CP; and test biopsychosocial risk factors associated with low HRQOL. METHODS: Data were acquired from the INternational Study Group of Pediatric Pancreatitis: In search for a cuRE registry. Baseline demographic and clinical questionnaires, the Child Health Questionnaire (measures HRQOL) and Child Behavior Checklist (measures emotional and behavioral functioning) were completed at enrollment. RESULTS: The sample included 368 children (54.3% girls, mean ageâ=â12.7years, standard deviation [SD]â=â3.3); 65.2% had ARP and 34.8% with CP. Low physical HRQOL (Mâ=â38.5, SDâ=â16.0) was demonstrated while psychosocial HRQOL (Mâ=â49.5, SDâ=â10.2) was in the normative range. Multivariate regression analysis revealed that clinical levels of emotional and behavioral problems (Bâ=â-10.28, Pâ <â0.001), episodic and constant abdominal pain (Bâ=â04.66, Pâ=â0.03; Bâ=â-13.25, Pâ<â0.001) were associated with low physical HRQOL, after accounting for ARP/CP status, age, sex, exocrine, and endocrine disease (F [9, 271]â=â8.34, Pâ<â0.001). Borderline and clinical levels of emotional and behavioral problems (Bâ=â-10.18, Pâ<â0.001; Bâ=â-15.98, Pâ<â0.001), and constant pain (Bâ=â-4.46, Pâ<â0.001) were associated with low psychosocial HRQOL (F [9, 271]â=â17.18, Pâ<â0.001). CONCLUSIONS: Findings highlight the importance of assessing HRQOL and treating pain and psychosocial problems in this vulnerable group of children.

BACKGROUND. Imaging findings represent key criteria for diagnosing chronic pancreatitis in children. Understanding radiologists' agreement for imaging findings is critical to standardizing and optimizing diagnostic criteria. OBJECTIVE. The purpose of this study is to evaluate the interobserver agreement among experienced pediatric radiologists for subjective, quantitative, and semiquantitative imaging findings of chronic pancreatitis in children. METHODS. In this retrospective study, CT or MRI examinations performed in children with chronic pancreatitis were submitted by six sites participating in the INSPPIRE (International Study Group of Pediatric Pancreatitis: In Search for a Cure) Consortium. One pediatric radiologist from each of the six sites reviewed examinations; three of the radiologists independently reviewed all CT examinations, and the other three radiologists independently reviewed all MRI examinations. Reviewers recorded 13 categoric imaging findings of chronic pancreatitis and measured pancreas thickness and pancreatic duct diameter. Agreement was assessed using kappa coefficients for the categoric variables and intraclass correlation coefficients (ICCs) for the continuous variables. RESULTS. A total of 76 CT and 80 MRI examinations performed in 110 children (65 girls and 45 boys; mean age, 11.3 ± 4.6 [SD] years) were reviewed. For CT, kappa coefficients for categoric findings ranged from -0.01 to 0.81, with relatively high kappa coefficients noted for parenchymal calcifications (κ = 0.81), main pancreatic duct dilatation (κ = 0.63), and atrophy (κ = 0.52). ICCs for parenchymal thickness measurements ranged from 0.57 in the pancreas head to 0.80 in the body and tail. The ICC for duct diameter was 0.85. For MRI, kappa coefficients for categoric findings ranged from -0.01 to 0.74, with relatively high kappa coefficients noted for main duct irregularity (κ = 0.74), side branch dilatation (κ = 0.70), number of dilated side branches (κ = 0.65), and main duct dilatation (κ = 0.64); kappa coefficient for atrophy was 0.52. ICCs for parenchymal thickness measurements ranged from 0.53 for the neck and body individually to 0.68 in the tail. ICC for duct diameter was 0.77. CONCLUSION. Interobserver agreement was fair to moderate for most CT and MRI findings of chronic pancreatitis in children. CLINICAL IMPACT. This study highlights challenges for the imaging diagnosis of pediatric chronic pancreatitis. Standardized and/or objective criteria are needed given the importance of imaging in diagnosis.

OBJECTIVES: Inadequate bowel preparation (IBP) for colonoscopy leads to missed diagnosis, longer anesthesia time, higher chance of complications and increased costs. Adult studies have demonstrated that patient characteristics such as male gender and obesity are associated with IBP. Little is known about factors affecting bowel preparation in children. Our aim was to determine factors associated with IBP in children. METHODS: We prospectively enrolled children undergoing outpatient colonoscopy. Quality of bowel preparation was assessed using Boston Bowel Preparation Scale (BBPS) score (range 0-9). Data collected included patient demographics, indication, and type of insurance. Patients were divided into two groups based on BBPS score-adequate (BBPS score > 5) and inadequate (BBPS score < 5) and groups were compared using Student t-test and chi-square test. Possible predictors were analyzed using multivariate logistic regression models. RESULTS: A total of 334 children were prospectively enrolled of whom 321 were studied further (age range 2-18âyears; mean age 12.4âyears; 60.4% female; 85.9% Caucasian). The mean BBPS score was 6.8 (standard deviation of ±2). IBP was reported in 12.8% (41/321). Multivariable logistic regression analysis did not show statistical differences between the groups in studied patient factors including age, gender, obesity, race, insurance type, and indication for colonoscopy. CONCLUSION: Contrary to several adult studies, the results of our prospective study did not show any relationship between examined patient factors and IBP in children. Interestingly, IBP was less prevalent in our pediatric study compared to published adult data (12.8% vs 20-40%).

Autoimmune pancreatitis (AIP) is a chronic inflammatory condition rarely reported in children. In 2018, to standardize the approach to AIP, INternational Study Group of Pediatric Pancreatitis: In search for a cuRE (INSPPIRE) defined AIP, outlined the clinical course, and developed diagnostic and therapeutic recommendations. We performed a retrospective review of cases at our institution from January 1, 2016, to June 1, 2019, and compared their presentations with the INSPPIRE guidelines. Our patients showed variable laboratory, radiographic, and histologic findings, highlighting the difficulty in diagnosing AIP. Histologic samples were obtained in our patients due to diagnostic uncertainty, which ultimately confirmed the diagnosis. One patient was diagnosed with autoimmune hepatitis coexistent with AIP, which has not been previously described in the pediatric population. Exocrine and endocrine complications of AIP were also noted. In all cases, symptoms improved following treatment, and decompression of the common bile duct was seen on repeat imaging.
RESUMEN
OBJECTIVE: The 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 DESIGN: Data 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. RESULTS: Out 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 (Pâ<â0.0001); white race in Northeast (Pâ=â0.009). CP was less common and time from diagnosis of first acute pancreatitis to CP was longer in children at non-US sites (Pâ=â0.0002 and Pâ=â0.011, respectively). Genetic mutations were most common among all groups; PRSS1 variants predominated in Midwest (Pâ=â0.002). Gallstones were more frequent in South (Pâ=â0.002). Endoscopic retrograde cholangiopancreatography (ERCP) and computed tomography (CT) imaging were more commonly utilized in United States compared with non-United States (Pâ<â0.0001), but there were no differences in the use of MRI/MRCP. Disease burden was highest in the West and Midwest, possibly as total pancreatectomy and islet autotransplantation (TPIAT) referral sites were located in these regions. All therapies were less commonly administered in non-US sites (Pâ<â0.0001). CONCLUSIONS: This is the first study to describe geographical variations in the INSPPIRE cohort, which possibly reflect variations in practice and referral patterns. The underlying reason behind the lower frequency of CP and fewer treatments in non-United States sites need to be further explored.

INTRODUCTION: Abdominal pain is common and is associated with high disease burden and health care costs in pediatric acute recurrent and chronic pancreatitis (ARP/CP). Despite the strong central component of pain in ARP/CP and the efficacy of psychological therapies for other centralized pain syndromes, no studies have evaluated psychological pain interventions in children with ARP/CP. The current trial seeks to 1) evaluate the efficacy of a psychological pain intervention for pediatric ARP/CP, and 2) examine baseline patient-specific genetic, clinical, and psychosocial characteristics that may predict or moderate treatment response. METHODS: This single-blinded randomized placebo-controlled multicenter trial aims to enroll 260 youth (ages 10-18) with ARP/CP and their parents from twenty-one INSPPIRE (INternational Study Group of Pediatric Pancreatitis: In search for a cuRE) centers. Participants will be randomly assigned to either a web-based cognitive behavioral pain management intervention (Web-based Management of Adolescent Pain Chronic Pancreatitis; WebMAP; N = 130) or to a web-based pain education program (WebED; N = 130). Assessments will be completed at baseline (T1), immediately after completion of the intervention (T2) and at 6 months post-intervention (T3). The primary study outcome is abdominal pain severity. Secondary outcomes include pain-related disability, pain interference, health-related quality of life, emotional distress, impact of pain, opioid use, and healthcare utilization. CONCLUSIONS: This is the first clinical trial to evaluate the efficacy of a psychological pain intervention for children with CP for reduction of abdominal pain and improvement of health-related quality of life. Findings will inform delivery of web-based pain management and potentially identify patient-specific biological and psychosocial factors associated with favorable response to therapy. Clinical Trial Registration #: NCT03707431.

OBJECTIVES: The aim of the study was to understand the association of frequent opioid use with disease phenotype and pain pattern and burden in children and adolescents with acute recurrent (ARP) or chronic pancreatitis (CP). METHODS: Cross-sectional study of children <19 years with ARP or CP, at enrollment into the INSPPIRE cohort. We categorized patients as opioid "frequent use" (daily/weekly) or "nonfrequent use" (monthly or less, or no opioids), based on patient and parent self-report. RESULTS: Of 427 children with ARP or CP, 17% reported frequent opioid use. More children with CP (65%) reported frequent opioid use than with ARP (41%, Pâ=â0.0002). In multivariate analysis, frequent opioid use was associated with older age at diagnosis (odds ratio [OR] 1.67 per 5 years, 95% confidence interval [CI] 1.13-2.47, Pâ=â0.01), exocrine insufficiency (OR 2.44, 95% CI 1.13-5.24, Pâ=â0.02), constant/severe pain (OR 4.14, 95% CI 2.06-8.34, Pâ<â0.0001), and higher average pain impact score across all 6 functional domains (OR 1.62 per 1-point increase, 95% CI 1.28-2.06, Pâ<â0.0001). Children with frequent opioid use also reported more missed school days, hospitalizations, and emergency room visits in the past year than children with no frequent use (Pâ<â0.0002 for each). Participants in the US West and Midwest accounted for 83% of frequent opioid users but only 56% of the total cohort. CONCLUSIONS: In children with CP or ARP, frequent opioid use is associated with constant pain, more healthcare use, and higher levels of pain interference with functioning. Longitudinal and prospective research is needed to identify risk factors for frequent opioid use and to evaluate nonopioid interventions for reducing pain and disability in these children.

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 for 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, BMI percentile, age at disease onset, disease risk factors, disease burden, and treatments were compared between children with DM (nâ=â24) and without DM (nâ=â373). RESULTS: Twenty-four children (6% 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% confidence interval (CI) 3-5.4] 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)]. CONCLUSION: 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.

OBJECTIVE: The 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 DESIGN: Data 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. RESULTS: Of 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; Pâ=â0.01). 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; Pâ=â0.003). 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%). CONCLUSIONS: Children 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.

OBJECTIVES: The aim of the present study was to investigate the natural history of chronic pancreatitis (CP); patients in the North American Pancreatitis Study2 (NAPS2, adults) and INternational Study group of Pediatric Pancreatitis: In search for a cuRE (INSPPIRE, pediatric) were compared. METHODS: Demographics, risk factors, disease duration, management and outcomes of 224 children and 1063 adults were compared using appropriate statistical tests for categorical and continuous variables. RESULTS: Alcohol was a risk in 53% of adults and 1% of children (Pâ<â0.0001); tobacco in 50% of adults and 7% of children (Pâ<â0.0001). Obstructive factors were more common in children (29% vs 19% in adults, Pâ=â0.001). Genetic risk factors were found more often in children. Exocrine pancreatic insufficiency was similar (children 26% vs adult 33%, Pâ=â0.107). Diabetes was more common in adults than children (36% vs 4% respectively, Pâ<â0.0001). Median emergency room visits, hospitalizations, and missed days of work/school were similar across the cohorts. As a secondary analysis, NAPS2 subjects with childhood onset (NAPS2-CO) were compared with INSPPIRE subjects. These 2 cohorts were more similar than the total INSPPIRE and NAPS2 cohorts, including for genetic risk factors. The only risk factor significantly more common in the NAPS2-CO cohort compared with the INSPPIRE cohort was alcohol (9% NAPS2-CO vs 1% INSPPIRE cohorts, Pâ=â0.011). CONCLUSIONS: Despite disparity in age of onset, children and adults with CP exhibit similarity in demographics, CP treatment, and pain. Differences between groups in radiographic findings and diabetes prevalence may be related to differences in risk factors associated with disease and length of time of CP.

INTRODUCTION: The significance of pancreas divisum (PD) as a risk factor for pancreatitis is controversial. We analyzed the characteristics of children with PD associated with acute recurrent or chronic pancreatitis to better understand its impact. PATIENTS AND METHODS: We compared children with or without PD in the well-phenotyped INSPPIRE (INternational Study group of Pediatric Pancreatitis: In search for a cuRE) cohort. Differences were analyzed using 2-sample t test or Wilcoxon rank sum test for continuous variables, Pearson χ or Fisher exact test for categorical variables. RESULTS: PD was found in 52 of 359 (14.5%) subjects, a higher prevalence than the general population (â¼7%). Females more commonly had PD (71% vs. 55%; P=0.02). Children with PD did not have a higher incidence of mutations in SPINK1, CFTR, CTRC compared with children with no PD. Children with PD were less likely to have PRSS1 mutations (10% vs. 34%; P<0.01) or a family history of pancreatitis (P<0.05), and more likely to have hypertriglyceridemia (11% vs. 3%; P=0.03). Children with PD underwent significantly more endoscopic procedures and pancreatic sphincterotomy. Patients with PD had fewer attacks of acute pancreatitis (P=0.03) and were less likely to develop exocrine pancreatic insufficiency (P=0.01). Therapeutic endoscopic retrograde cholangiopancreatography was considered most helpful if pancreatic duct was impacted with stones (83% helpful). CONCLUSIONS: PD is likely a risk factor for acute recurrent pancreatitis and chronic pancreatitis in children that appears to act independently of genetic risk factors. Patients with PD and stones obstructing the pancreatic duct benefit most from therapeutic endoscopic retrograde cholangiopancreatography.

We created the INternational Study Group of Pediatric Pancreatitis: In Search for a CuRE (INSPPIRE 2) cohort to study the risk factors, natural history, and outcomes of pediatric acute recurrent pancreatitis and chronic pancreatitis (CP). Patient and physician questionnaires collect information on demographics, clinical history, family and social history, and disease outcomes. Health-related quality of life, depression, and anxiety are measured using validated questionnaires. Information entered on paper questionnaires is transferred into a database managed by Consortium for the Study of Chronic Pancreatitis, Diabetes, and Pancreatic Cancer's Coordinating and Data Management Center. Biosamples are collected for DNA isolation and analysis of most common pancreatitis-associated genes.Twenty-two sites (18 in the United States, 2 in Canada, and 1 each in Israel and Australia) are participating in the INSPPIRE 2 study. These sites have enrolled 211 subjects into the INSPPIRE 2 database toward our goal to recruit more than 800 patients in 2 years. The INSPPIRE 2 cohort study is an extension of the INSPPIRE cohort study with a larger and more diverse patient population. Our goals have expanded to include evaluating risk factors for CP, its sequelae, and psychosocial factors associated with pediatric acute recurrent pancreatitis and CP.

OBJECTIVE: The aim of this study was to assess the impact of obesity on pediatric acute recurrent pancreatitis or chronic pancreatitis (CP). METHODS: We determined body mass index (BMI) status at enrollment in INSPPIRE (INternational Study group of Pediatric Pancreatitis: In search for a cuRE) cohort using CDC criteria for pediatric-specific BMI percentiles. We used the Cochran-Armitage test to assess trends and the Jonckheere-Terpstra test to determine associations. RESULTS: Of 446 subjects (acute recurrent pancreatitis, n = 241; CP, n = 205), 22 were underweight, 258 normal weight, 75 overweight, and 91 were obese. The BMI groups were similar in sex, race, and age at presentation. Hypertriglyceridemia was more common in overweight or obese. Obese children were less likely to have CP and more likely to have acute inflammation on imaging. Compared with children with normal weight, obese or overweight children were older at first acute pancreatitis episode and diagnosed with CP at an older age. Obese or overweight children were less likely to undergo medical or endoscopic treatment, develop exocrine pancreatic insufficiency, and require total pancreatectomy with islet autotransplantation. Diabetes was similar among all groups. CONCLUSIONS: Obesity or overweight seems to delay the initial acute pancreatitis episode and diagnosis of CP compared with normal weight or underweight. The impact of obesity on pediatric CP progression and severity deserves further study.

OBJECTIVES: Patients with inflammatory bowel disease (IBD) often receive immunosuppressive therapy, which may make them vulnerable to infections such as hepatitis B. We hypothesized that hepatitis B virus titers are low in the vaccinated pediatric population with IBD. The aims of our study were to identify the incidence of lower titers of hepatitis B surface antibody (HBsAb) and determine which patient factors may be associated with lower HBsAb titers. METHODS: Patients with diagnosis of IBD, ages 5 to 18 years, were prospectively enrolled. Patients were confirmed to have had a full series of hepatitis B vaccination. Quantitative serum HBsAb titers were measured and logistic regression analysis with independent variables of age, sex, race, disease phenotype, surgery, medications and a dependent variable of adequate HBsAb titers (> 10âmIU/mL) was performed. RESULTS: Of the 116 patients enrolled, 57 were boys and 59 were girls. 75 patients had a diagnosis of Crohn disease; 32 had a diagnosis of ulcerative colitis; and 9 patients had been diagnosed as having indeterminate colitis. At the time of the study, 15 patients were taking corticosteroid, 66 on an immunomodulator, and 53 on a biologic. Sixty percent of patients in the 5- to 10-year age group had protective titers versus 22% to 27% in the older groups, Pâ=â0.04. Only 28% of the 116 patients had HBsAb titers of >10mâIU/mL. Twenty percent of the patients taking corticosteroids, 27% taking immunomodulators, and 24% taking biologics were found to be seroimmune. CONCLUSIONS: Nearly two-thirds of pediatric patients with IBD have low titers against hepatitis B virus. Titers were highest in the younger patients. No patient-specific variable, such as the use of immunosuppressants, appeared to influence these low titers.

OBJECTIVES: Asynchronous learning, using Web-based instruction, is developing a growing role in medical education. Restrictions on resident work hours continue to require restructuring of formal educational activities in many programs. The objectives of this curriculum development project was to determine whether using blended learning with case-based online modules supplemented by faculty-facilitated case discussion was effective and well received. METHODS: The pediatric gastroenterology curriculum, completed during a 4-week subspecialty rotation, consists of 8 case-based online modules and four 1-hour didactic sessions. The curriculum was pilot tested using a 1-group, pretest/posttest design as well as a survey to assess both knowledge acquisition and learner satisfaction. Resident evaluations of the rotation were examined during a 4-year pre- and postimplementation period. RESULTS: Twenty-one learners participated in pilot testing of the curriculum. After completing the curriculum, there was a significant improvement in post-test medical knowledge scores (pretest 73%, posttest 92%, P < 0.001). The satisfaction survey showed that learners were highly satisfied with the course format, and this teaching method was actually preferred to more traditional methods of teaching. Pilot learners reported increased comfort in caring for patients with gastrointestinal complaints. Evaluations of the gastroenterology rotation improved significantly across multiple domains in the years after implementation of the curriculum. CONCLUSIONS: This curriculum, which uses online teaching reinforced by faculty-facilitated case discussion, was both effective and well received by learners. The implementation of this curriculum appears to have had sustained beneficial effects on the learning environment beyond the simple acquisition of medical knowledge.
