Item Impact of Obesity on Pediatric Acute Recurrent and Chronic Pancreatitis(Wolters Kluwer, 2018-09) Uc, Aliye; Zimmerman, M. Bridget; Wilschanski, Michael; Werlin, Steven L.; Troendle, David; Shah, Uzma; Schwarzenberg, Sarah Jane; Rhee, Sue; Pohl, John F.; Perito, Emily R.; Palermo, Joseph J.; Ooi, Chee Y.; Liu, Quin; Lin, Tom K.; Morinville, Veronique D.; McFerron, Brian A.; Husain, Sohail Z.; Himes, Ryan; Heyman, Melvin B.; Gonska, Tanja; Giefer, Matthew J.; Gariepy, Cheryl E.; Freedman, Steven D.; Fishman, Douglas S.; Bellin, Melena D.; Barth, Bradley; Abu-El-Haija, Maisam; Lowe, Mark E.; Pediatrics, School of MedicineOBJECTIVE: 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.Item Pancreas Divisum in Pediatric Acute Recurrent and Chronic Pancreatitis: Report From INSPPIRE(Wolters Kluwer, 2019-07-01) Lin, Tom K.; Abu-El-Haija, Maisam; Nathan, Jaimie D.; Palermo, Joseph P.; Barth, Bradley; Bellin, Melena; Fishman, Douglas S.; Freedman, Steven D.; Gariepy, Cheryl E.; Giefer, Matthew J.; Gonska, Tanja; Heyman, Melvin B.; Himes, Ryan; Husain, Sohail Z.; Liu, Quin; Maqbool, Asim; Mascarenhas, Maria; McFerron, Brian; Morinville, Veronique D.; Ooi, Chee Y.; Perito, Emily; Pohl, John F.; Rhee, Sue; Schwarzenberg, Sarah Jane; Shah, Uzma; Troendle, David; Werlin, Steven L.; Wilschanski, Michael; Zimmerman, M. Bridget; Lowe, Mark E.; Uc, Aliye; Pediatrics, School of MedicineThe 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 χ2 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 (∼7%). 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.Item Risk Factors for Rapid Progression From Acute Recurrent to Chronic Pancreatitis in Children: Report From INSPPIRE(Wolters Kluwer, 2019-08-01) Liu, Quin Y.; Abu-El-Haija, Maisam; Husain, Sohail Z.; Barth, Bradley; Bellin, Melena; Fishman, Douglas S.; Freedman, Steven D.; Gariepy, Cheryl E.; Giefer, Matthew J.; Gonska, Tanja; Heyman, Melvin B.; Himes, Ryan; Lin, Tom K.; Maqbool, Asim; Mascarenhas, Maria; McFerron, Brian A.; Morinville, Veronique D.; Nathan, Jaimie D.; Ooi, Chee Y.; Perito, Emily R.; Pohl, John F.; Rhee, Sue; Schwarzenberg, Sarah J.; Shah, Uzma; Troendle, David; Werlin, Steven L.; Wilschanski, Michael; Zimmerman, M. Bridget; Lowe, Mark E.; Uc, Aliye; Pediatrics, School of MedicineObjective 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 (non-progression) probability distribution between groups. Cox proportional hazard regression models were fitted to obtain hazard ratio (with 95% CI) of progression for each risk variable. Results Of 442 children, 251 had ARP, 191 CP. The median time of progression from initial attack of AP to CP was 3.79 years. The progression was faster in those age ≥6 years at the first episode of AP compared to those age <6 years (median time to CP: 2.91 vs 4.92 years; p=0.01). Children with pathogenic PRSS1 variants progressed more rapidly to CP compared to children without PRSS1 variants (median time to CP: 2.52 vs 4.48 years; p=0.003). Within six years after the initial AP attack, cumulative proportion with exocrine pancreatic insufficiency (EPI) 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, EPI and diabetes. The progression to CP is faster in children who were ≥6 years at the first episode of AP or with pathogenic PRSS1 variants. The factors that impact the aggressive disease course in childhood warrant further investigation.
