Item Analysis of INSPPIRE-2 Cohort: Risk Factors and Disease Burden in Children with Acute Recurrent or Chronic Pancreatitis(Wiley, 2022-11) Uc, Aliye; Cress, Gretchen A.; Wang, Fuchenchu; Abu-El-Haija, Maisam; Ellery, Kate M.; Fishman, Douglas S.; Gariepy, Cheryl E.; Gonska, Tanja; Lin, Tom K.; Liu, Quin Y.; Mehta, Megha; Maqbool, Asim; McFerron, Brian A.; Morinville, Veronique D.; Ooi, Chee Y.; Perito, Emily R.; Schwarzenberg, Sarah Jane; Sellers, Zachary M.; Serrano, Jose; Shah, Uzma; Troendle, David M.; Wilschanski, Michael; Zheng, Yuhua; Yuan, Ying; Lowe, Mark E.; Consortium for the Study of Chronic Pancreatitis, Diabetes and Pancreatic Cancer; Pediatrics, School of MedicineObjectives: 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 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. 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 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.Item Analysis of INSPPIRE-2 Cohort: Risk Factors and Disease Burden in Children with Acute Recurrent or Chronic Pancreatitis(Wiley, 2022) Uc, Aliye; Cress, Gretchen A.; Wang, Fuchenchu; Abu-El-Haija, Maisam; Ellery, Kate M.; Fishman, Douglas S.; Gariepy, Cheryl E.; Gonska, Tanja; Lin, Tom K.; Liu, Quin Y.; Mehta, Megha; Maqbool, Asim; McFerron, Brian A.; Morinville, Veronique D.; Ooi, Chee Y.; Perito, Emily R.; Schwarzenberg, Sarah Jane; Sellers, Zachary M.; Serrano, Jose; Shah, Uzma; Troendle, David M.; Wilschanski, Michael; Zheng, Yuhua; Yuan, Ying; Lowe, Mark E.; Pediatrics, School of MedicineObjectives: The objective of this study is to investigate risk factors and disease burden in pediatric acute recurrent pancreatitis (ARP) and chronic pancreatitis (CP).

Jay; Pediatrics, School of MedicineMethods to identify children with cystic fibrosis (CF) at risk for development of advanced liver disease are lacking. We aim to determine the association between liver stiffness measurement (LSM) by vibration-controlled transient elastography (VCTE) with research ultrasound (US) patterns and conventional hepatic markers as a potential means to follow liver disease progression in children with CF. ELASTIC (Longitudinal Assessment of Transient Elastography in CF) is a nested cohort of 141 patients, ages 7-21, enrolled in the Prediction by US of Risk of Hepatic Cirrhosis in CF (PUSH) Study. We studied the association between LSM with research-grade US patterns (normal [NL], heterogeneous [HTG], homogeneous [HMG], or nodular [NOD]) and conventional hepatic markers. In a subgroup (n = 79), the association between controlled attenuation parameter (CAP) and US pattern was explored. Among 133 subjects undergoing VCTE, NOD participants (n = 26) had a significantly higher median (interquartile range) LSM of 9.1 kPa (6.3, 15.8) versus NL (n = 72, 5.1 kPa [4.2, 7.0]; P < 0.0001), HMG (n = 17, 5.9 kPa [5.2, 7.8]; P = 0.0013), and HTG (n = 18, 6.1 kPa [4.7, 7.0]; P = 0.0008) participants. HMG participants (n = 14) had a significantly higher mean CAP (SD) (270.5 dB/m [61.1]) compared with NL (n = 40, 218.8 dB/m [46.5]; P = 0.0027), HTG (n = 10, 218.1 dB/m [60.7]; P = 0.044), and NOD (n = 15, 222.7 dB/m [56.4]; P = 0.041) participants. LSM had a negative correlation with platelet count (rs = − 0.28, P = 0.0071) and positive correlation with aspartate aminotransferase-to-platelet ratio index (rs = 0.38, P = 0.0002), Fibrosis-4 index (rs = 0.36, P = 0.0007), gamma-glutamyltransferase (GGT; rs = 0.35, P = 0.0017), GGT-to-platelet ratio (rs = 0.35, P = 0.003), and US spleen size z-score (rs = 0.27, P = 0.0073). Conclusion: VCTE is associated with US patterns and conventional markers in patients with liver disease with CF.Item Clinical and Practice Variations in Pediatric Acute Recurrent or Chronic Pancreatitis: Report From the INSPPIRE Study(Wolters Kluwer, 2020-07) Dike, Chinenye R.; Zimmerman, Bridget; Zheng, Yuhua; Wilschanski, Michael; Werlin, Steven L.; Troendle, David; Shah, Uzma; Schwarzenberg, Sarah Jane; Pohl, John; Perito, Emily R.; Ooi, Chee Y.; Nathan, Jaimie D.; Morinville, Veronique D.; McFerron, Brian; Mascarenhas, Maria; Maqbool, Asim; Liu, Quin; Lin, Tom K.; Husain, Sohail Z.; Heyman, Melvin B.; Gonska, Tanja; Giefer, Matthew J.; Gariepy, Cheryl E.; Fishman, Douglas S.; Bellin, Melena; Barth, Bradley; Abu-El-Haija, Maisam; Lowe, Mark E.; Uc, Aliye; Pediatrics, School of MedicineObjective: 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 (P < 0.0001); white race in Northeast (P = 0.009). CP was less common and time from diagnosis of first acute pancreatitis to CP was longer in children at non-US sites (P = 0.0002 and P = 0.011, respectively). Genetic mutations were most common among all groups; PRSS1 variants predominated in Midwest (P = 0.002). Gallstones were more frequent in South (P = 0.002). Endoscopic retrograde cholangiopancreatography (ERCP) and computed tomography (CT) imaging were more commonly utilized in United States compared with non-United States (P < 0.0001), 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 (P < 0.0001). 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.Item Health-related Quality of Life in a Prospective Study of Ultrasound to Detect Cystic Fibrosis-related Liver Disease in Children(Wiley, 2022) Schwarzenberg, Sarah Jane; Palermo, Joseph J.; Ye, Wen; Huang, Suiyuan; Magee, John C.; Alazraki, Adina; Freeman, A. Jay; Harned, Roger; Karmazyn, Boaz; Karnsakul, Wikrom; Leung, Daniel H.; Ling, Simon C.; Masand, Prakash; Molleston, Jean P.; Murray, Karen F.; Navarro, Oscar M.; Nicholas, Jennifer L.; Otto, Randolph K.; Paranjape, Shruti M.; Siegel, Marilyn J.; Stoll, Janis; Towbin, Alexander J.; Narkewicz, Michael R.; Alonso, Estella M.; CFLD NET; Pediatrics, School of MedicineObjectives: Cystic fibrosis liver disease (CFLD) begins early in life. Symptoms may be vague, mild, or nonexistent. Progressive liver injury may be associated with decrements in patient health before liver disease is clinically apparent. We examined Health-Related Quality of Life (HRQOL) in children enrolled in a multi-center study of CFLD to determine the impact of early CFLD on general and disease-specific QOL. Methods: Ultrasound (US) patterns of normal (NL), heterogeneous (HTG), homogeneous (HMG), or nodular (NOD) were assigned in a prospective manner to predict those at risk for advanced CFLD. Parents were informed of results. We assessed parent/child-reported (age ≥5 years) HRQOL by PedsQL 4.0 Generic Core and CF Questionnaire-revised (CFQ-R) prior to US and annually. HRQOL scores were compared by US pattern at baseline (prior to US), between baseline and 1 year and at 5 years. Multivariate analysis of variance (MANOVA) with Hotelling-Lawley trace tested for differences among US groups. Results: Prior to US, among 515 participants and their parents there was no evidence that HTG or NOD US was associated with reduced PedsQL/CFQ-R at baseline. Parents of NOD reported no change in PedsQL/CFQ-R over the next year. Child-report PedsQL/CFQ-R (95 NL, 20 NOD) showed improvement between baseline and year 5 for many scales, including Physical Function. Parents of HMG children reported improved CFQ-R scores related to weight. Conclusions: Early undiagnosed or pre-symptomatic liver disease had no impact on generic or disease-specific HRQoL, and HRQoL was remarkably stable in children with CF regardless of liver involvement.Item Health-related Quality of Life in a Prospective Study of Ultrasound to Detect Cystic Fibrosis-related Liver Disease in Children(Wiley, 2022-09-06) Schwarzenberg, Sarah Jane; Palermo, Joseph J.; Ye, Wen; Huang, Suiyuan; Magee, John C.; Alazraki, Adina; Freeman, A.

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 age = 12.7years, standard deviation [SD] = 3.3); 65.2% had ARP and 34.8% with CP. Low physical HRQOL (M = 38.5, SD = 16.0) was demonstrated while psychosocial HRQOL (M = 49.5, SD = 10.2) was in the normative range. Multivariate regression analysis revealed that clinical levels of emotional and behavioral problems (B = -10.28, P < 0.001), episodic and constant abdominal pain (B = 04.66, P = 0.03; B = -13.25, P < 0.001) were associated with low physical HRQOL, after accounting for ARP/CP status, age, sex, exocrine, and endocrine disease (F [9, 271] = 8.34, P < 0.001). Borderline and clinical levels of emotional and behavioral problems (B = -10.18, P < 0.001; B = -15.98, P < 0.001), and constant pain (B = -4.46, P < 0.001) were associated with low psychosocial HRQOL (F [9, 271] = 17.18, P < 0.001). Conclusions: Findings highlight the importance of assessing HRQOL and treating pain and psychosocial problems in this vulnerable group of children.Item Heterogeneous liver on research ultrasound identifies children with cystic fibrosis at high risk of advanced liver disease(Elsevier, 2023) Siegel, Marilyn J.; Leung, Daniel H.; Molleston, Jean P.; Ye, Wen; Paranjape, Shruti M.; Freeman, A. Jay; Palermo, Joseph J.; Stoll, Janis; Masand, Prakash; Karmazyn, Boaz; Harned, Roger; Ling, Simon C.; Navarro, Oscar M.; Karnsakul, Wikrom; Alazraki, Adina; Schwarzenberg, Sarah Jane; Towbin, Alex J.; Alonso, Estella M.; Nicholas, Jennifer L.; Green, Nicole; Otto, Randolph K.; Magee, John C.; Narkewicz, Michael R.; CFLD Network; Pediatrics, School of MedicineBackground: This study examines whether heterogeneous (HTG) pattern on liver ultrasound (US) identifies children at risk for advanced cystic fibrosis liver disease (aCFLD). Methods: Prospective 6-year multicenter case-controlled cohort study. Children with pancreatic insufficient cystic fibrosis (CF) aged 3-12 years without known cirrhosis underwent screening US. Participants with HTG were matched (by age, Pseudomonas infection status and center) 1:2 with participants with normal (NL) US pattern. Clinical status and laboratory data were obtained annually and US bi-annually for 6 years. Primary endpoint was development of nodular (NOD) US pattern consistent with aCFLD. Results: 722 participants underwent screening US, with 65 HTG and 592 NL. Final cohort included 55 HTG and 116 NL with ≥ 1 follow-up US. ALT, AST, GGTP, FIB-4, GPR and APRI were higher, and platelets were lower in HTG compared to NL. HTG had a 9.5-fold increased incidence (95% confidence interval [CI]:3.4, 26.7, p<0.0001, 32.7% vs 3.4%) of NOD versus NL. HTG had a sensitivity of 82% and specificity of 75% for subsequent NOD. Negative predictive value of a NL US for subsequent NOD was 96%. Multivariate logistic prediction model that included baseline US, age, and log(GPR) improved the C-index to 0.90 compared to only baseline US (C-index 0.78). Based on survival analysis, 50% of HTG develop NOD after 8 years. Conclusions: Research US finding of HTG identifies children with CF with a 30-50% risk for aCFLD. A score based on US pattern, age and GPR may refine the identification of individuals at high risk for aCFLD.Item Heterogeneous Liver on Research Ultrasound Identifies Children with Cystic Fibrosis at High Risk of Advanced Liver Disease: Interim Results of a Prospective Observational Case-Controlled Study(Elsevier, 2020-04) Siegel, Marilyn J.; Freeman, A. Jay; Ye, Wen; Palermo, Joseph J.; Molleston, Jean P.; Paranjape, Shruti M.; Stoll, Janis; Leung, Daniel; Masand, Prakash; Karmazyn, Boaz; Harned, Roger; Ling, Simon C.; Navarro, Oscar M.; Karnsakul, Wikrom; Alazraki, Adina; Schwarzenberg, Sarah Jane; Seidel, F. Glen; Towbin, Alex; Alonso, Estella M.; Nicholas, Jennifer L.; Murray, Karen F.; Otto, Randolph K.; Sherker, Averell H.; Magee, John C.; Narkewicz, Michael R.; Pediatrics, School of MedicineObjective: To assess if a heterogeneous pattern on research liver ultrasound examination can identify children at risk for advanced cystic fibrosis (CF) liver disease. Study design: Planned 4-year interim analysis of a 9-year multicenter, case-controlled cohort study (Prospective Study of Ultrasound to Predict Hepatic Cirrhosis in CF). Children with pancreatic insufficient CF aged 3-12 years without known cirrhosis, Burkholderia species infection, or short bowel syndrome underwent a screening research ultrasound examination. Participants with a heterogeneous liver ultrasound pattern were matched (by age, Pseudomonas infection status, and center) 1:2 with participants with a normal pattern. Clinical status and laboratory data were obtained annually and research ultrasound examinations biannually. The primary end point was the development of a nodular research ultrasound pattern, a surrogate for advanced CF liver disease. Results: There were 722 participants who underwent screening research ultrasound examination, of which 65 were heterogeneous liver ultrasound pattern and 592 normal liver ultrasound pattern. The final cohort included 55 participants with a heterogeneous liver ultrasound pattern and 116 participants with a normal liver ultrasound pattern. All participants with at least 1 follow-up research ultrasound were included. There were no differences in age or sex between groups at entry. Alanine aminotransferase (42 ± 22 U/L vs 32 ± 19 U/L; P = .0033), gamma glutamyl transpeptidase (36 ± 34 U/L vs 15 ± 8 U/L; P < .001), and aspartate aminotransferase to platelet ratio index (0.7 ± 0.5 vs 0.4 ± 0.2; P < .0001) were higher in participants with a heterogeneous liver ultrasound pattern compared with participants with a normal liver ultrasound pattern. Participants with a heterogeneous liver ultrasound pattern had a 9.1-fold increased incidence (95% CI, 2.7-30.8; P = .0004) of nodular pattern vs a normal liver ultrasound pattern (23% in heterogeneous liver ultrasound pattern vs 2.6% in normal liver ultrasound pattern). Conclusions: Research liver ultrasound examinations can identify children with CF at increased risk for developing advanced CF liver disease.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.
