Item Association Between Transient Elastography and Controlled Attenuated Parameter and Liver Ultrasound in Children With Cystic Fibrosis(Wolters Kluwer, 2021-05-13) Ye, Wen; Leung, Daniel H.; Molleston, Jean P.; Ling, Simon C.; Murray, Karen F.; Nicholas, Jennifer L.; Huang, Suiyuan; Karmazyn, Boaz W.; Harned, Roger K.; Masand, Prakash; Alazraki, Adina L.; Navarro, Oscar M.; Otto, Randolph K.; Palermo, Joseph J.; Towbin, Alexander J.; Alonso, Estella M.; Karnsakul, Wikrom W.; Schwarzenberg, Sarah Jane; Seidel, Glenn F.; Siegel, Marilyn; Magee, John C.; Narkewicz, Michael R.; Freeman, A. 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 Baseline ultrasound and clinical correlates in children with cystic fibrosis.(Elsevier, 2015-10) Leung, Daniel H.; Ye, Wen; Molleston, Jean P.; Weymann, Alexander; Ling, Simon; Paranjape, Shruti M.; Romero, Rene; Schwarzenberg, Sara Jane; Palermo, Joseph; Alonso, Estella M.; Murray, Karen F.; Marshall, Bruce C.; Sherker, Averell H.; Siegel, Marilyn J.; Krishnamurthy, Rajesh; Harned, Roger; Karmazyn, Boaz; Magee, John C.; Narkewicz, Michael R.; Department of Pediatrics, IU School of MedicineObjective: To investigate the relationship between abdominal ultrasound (US) findings and demographic, historical and clinical features in children with CF. Study design: Children age 3-12 years with CF without known cirrhosis, were enrolled in a prospective, multi-center study of US to predict hepatic fibrosis. Consensus US patterns were assigned by 3 radiologists as normal, heterogeneous, homogeneous, or cirrhosis. Data were derived from direct collection and U.S. or Toronto CF registries. Chi-square or ANOVA were used to compare variables among US groups and between normal and abnormal. Logistic regression was used to study risk factors for having abnormal US. Results: Findings in 719 subjects were normal (n=590, 82.1%), heterogeneous (64, 8.9%), homogeneous (41, 5.7%), and cirrhosis (24, 3.3%). Cirrhosis (p=0.0004), homogeneous (p<0.0001) and heterogeneous (p=0.03) were older than normal. More males were heterogeneous (p=0.001). More heterogeneous (15.0%, p=0.009) and cirrhosis (25.0%, p=0.005) hadItem 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.

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 Steroid Therapy on Early Growth in Infants with Biliary Atresia: The Multicenter Steroids in Biliary Atresia Randomized Trial(Elsevier, 2018-11) Alonso, Estella M.; Ye, Wen; Hawthorne, Kieran; Venkat, Veena; Loomes, Kathleen M.; Mack, Cara L.; Hertel, Paula M.; Karpen, Saul J.; Kerkar, Nanda; Molleston, Jean P.; Murray, Karen F.; Romero, Rene; Rosenthal, Philip; Schwarz, Kathleen B.; Shneider, Benjamin L.; Suchy, Frederick J.; Turmelle, Yumirle P.; Wang, Kasper S.; Sherker, Averell H.; Sokol, Ronald J.; Bezerra, Jorge A.; Magee, John C.; Pediatrics, School of MedicineOBJECTIVE: To investigate the impact of corticosteroid therapy on the growth of participants in the Steroids in Biliary Atresia Randomized Trial (START) conducted through the Childhood Liver Disease Research Network. The primary analysis in START indicated that steroids did not have a beneficial effect on drainage in a cohort of infants with biliary atresia. We hypothesized that steroids would have a detrimental effect on growth in these infants. STUDY DESIGN: A total of 140 infants were enrolled in START, with 70 randomized to each treatment arm: steroid and placebo. Length, weight, and head circumference were obtained at baseline and follow-up visits to 24 months of age. RESULTS: Patients treated with steroids had significantly lower length and head circumference z scores during the first 3 months post-hepatoportoenterostomy (HPE), and significantly lower weight until 12 months. Growth trajectories in the steroid and placebo arms differed significantly for length (P < .0001), weight (P = .009), and head circumference (P < .0001) with the largest impact noted for those with successful HPE. Growth trajectory for head circumference was significantly lower in patients treated with steroids irrespective of HPE status, but recovered during the second 6 months of life. CONCLUSIONS: Steroid therapy following HPE in patients with biliary atresia is associated with impaired length, weight, and head circumference growth trajectories for at least 6 months post-HPE, especially impacting infants with successful bile drainage.Item Long-term follow-up and liver outcomes in children with cystic fibrosis and nodular liver on ultrasound in a multi-center study(Elsevier, 2023) Leung, Daniel H.; Ye, Wen; Schwarzenberg, Sarah J.; Freeman, A. Jay; Palermo, Joseph J.; Weymann, Alexander; Alonso, Estella M.; Karnsakul, Wikrom W.; Murray, Karen F.; Stoll, Janis M.; Huang, Suiyuan; Karmazyn, Boaz; Masand, Prakash; Magee, John C.; Alazraki, Adina L.; Towbin, Alexander J.; Nicholas, Jennifer L.; Green, Nicole; Otto, Randolph K.; Siegel, Marilyn J.; Ling, Simon C.; Navarro, Oscar M.; Harned, Roger K.; Narkewicz, Michael R.; Molleston, Jean P.; CFLD Research Network; Pediatrics, School of MedicineBackground: Nodular liver (NOD) in cystic fibrosis (CF) suggests advanced CF liver disease (aCFLD); little is known about progression of liver disease (LD) after detection of sonographic NOD. Methods: Clinical, laboratory, and ultrasound (US) data from Prediction by Ultrasound of the Risk of Hepatic Cirrhosis in CFLD Study participants with NOD at screening or follow-up were compared with normal (NL). Linear mixed effects models were used for risk factors for LD progression and Kaplan-Meier estimator for time-to-event. Results: 54 children with NOD (22 screening, 32 follow-up) and 112 NL were evaluated. Baseline (BL) and trajectory of forced expiratory volume, forced vital capacity, height/BMI z-scores were similar in NOD vs NL. Platelets were lower in NOD at BL (250 vs 331×103/microL; p < 0.001) and decreased by 8600/year vs 2500 in NL. Mean AST to Platelet Ratio Index (1.1 vs 0.4; p < 0.001), Fibrosis-4 Index (0.4 vs 0.2, p < 0.001), and spleen size z-score (SSZ) [1.5 vs 0.02; p < 0.001] were higher in NOD at BL; SSZ increased by 0.5 unit/year in NOD vs 0.1 unit/year in NL. Median liver stiffness (LSM) by transient elastography was higher in NOD (8.2 kPa, IQR 6-11.8) vs NL (5.3, 4.2-7, p < 0.0001). Over 6.3 years follow-up (1.3-10.3), 6 NOD had esophageal varices (cumulative incidence in 10 years: 20%; 95% CI: 0.0%, 40.0%), 2 had variceal bleeding, and 2 underwent liver transplantation; none had ascites or hepatic encephalopathy. No NL experienced liver-related events. Conclusions: NOD developed clinically evident portal hypertension faster than NL without worse growth or lung disease.Item Mutation Analysis and Disease Features at Presentation in a Multi-Center Cohort of Children With Monogenic Cholestasis(Wiley, 2021) Hertel, Paula M.; Bull, Laura N.; Thompson, Richard J.; Goodrich, Nathan P.; Ye, Wen; Magee, John C.; Squires, Robert H.; Bass, Lee M.; Heubi, James E.; Kim, Grace E.; Ranganathan, Sarangarajan; Schwarz, Kathleen B.; Bozic, Molly A.; Horslen, Simon P.; Clifton, Matthew S.; Turmelle, Yumirle P.; Suchy, Frederick J.; Superina, Riccardo A.; Wang, Kasper S.; Loomes, Kathleen M.; Kamath, Binita M.; Sokol, Ronald J.; Shneider, Benjamin L.; Childhood Liver Disease Research Network (ChiLDReN); Pediatrics, School of MedicineObjectives: To advance our understanding of monogenic forms of intrahepatic cholestasis. Methods: Analyses included participants with pathogenic biallelic mutations in adenosine triphosphate (ATP)-binding cassette subfamily B member 11 (ABCB11) (bile salt export pump; BSEP) or adenosine triphosphatase (ATPase) phospholipid transporting 8B1 (ATP8B1) (familial intrahepatic cholestasis; FIC1), or those with monoallelic or biallelic mutations in adenosine triphosphate (ATP)-binding cassette subfamily B member 4 (ABCB4) (multidrug resistance; MDR3), prospectively enrolled in the Longitudinal Study of Genetic Causes of Intrahepatic Cholestasis (LOGIC; NCT00571272) between November 2007 and December 2013. Summary statistics were calculated to describe baseline demographics, history, anthropometrics, laboratory values, and mutation data. Results: Ninety-eight participants with FIC1 (n = 26), BSEP (n = 53, including 8 with biallelic truncating mutations [severe] and 10 with p.E297G or p.D482G [mild]), or MDR3 (n = 19, including four monoallelic) deficiency were analyzed. Thirty-five had a surgical interruption of the enterohepatic circulation (sEHC), including 10 who underwent liver transplant (LT) after sEHC. Onset of symptoms occurred by age 2 years in most with FIC1 and BSEP deficiency, but was later and more variable for MDR3. Pruritus was nearly universal in FIC1 and BSEP deficiency. In participants with native liver, failure to thrive was common in FIC1 deficiency, high ALT was common in BSEP deficiency, and thrombocytopenia was common in MDR3 deficiency. sEHC was successful after more than 1 year in 7 of 19 participants with FIC1 and BSEP deficiency. History of LT was most common in BSEP deficiency. Of 102 mutations identified, 43 were not previously reported. Conclusions: In this cohort, BSEP deficiency appears to be correlated with a more severe disease course. Genotype-phenotype correlations in these diseases are not straightforward and will require the study of larger cohorts.Item Neurodevelopmental Outcome of Young Children with Biliary Atresia and Native Liver: Results from the ChiLDReN Study(Elsevier, 2018-05) Ng, Vicky L.; Sorensen, Lisa G.; Alonso, Estella M.; Fredericks, Emily M.; Ye, Wen; Moore, Jeff; Karpen, Saul J.; Shneider, Benjamin L.; Molleston, Jean P.; Bezerra, Jorge A.; Murray, Karen F.; Loomes, Kathleen M.; Rosenthal, Philip; Squires, Robert H.; Wang, Kasper; Arnon, Ronen; Schwarz, Kathleen B.; Turmelle, Yumirle P.; Haber, Barbara H.; Sherker, Averell H.; Magee, John C.; Sokol, Ronald J.; Pediatrics, School of MedicineOBJECTIVES: To assess neurodevelopmental outcomes among participants with biliary atresia with their native liver at ages 12 months (group 1) and 24 months (group 2), and to evaluate variables predictive of neurodevelopmental impairment. STUDY DESIGN: Participants enrolled in a prospective, longitudinal, multicenter study underwent neurodevelopmental testing with either the Bayley Scales of Infant Development, 2nd edition, or Bayley Scales of Infant and Toddler Development, 3rd edition. Scores (normative mean = 100 ± 15) were categorized as ≥100, 85-99, and <85 for χ2 analysis. Risk for neurodevelopmental impairment (defined as ≥1 score of <85 on the Bayley Scales of Infant Development, 2nd edition, or Bayley Scales of Infant and Toddler Development, 3rd edition, scales) was analyzed using logistic regression. RESULTS: There were 148 children who completed 217 Bayley Scales of Infant and Toddler Development, 3rd edition, examinations (group 1, n = 132; group 2, n = 85). Neurodevelopmental score distributions significantly shifted downward compared with test norms at 1 and 2 years of age. Multivariate analysis identified ascites (OR, 3.17; P = .01) and low length z-scores at time of testing (OR, 0.70; P < .04) as risk factors for physical/motor impairment; low weight z-score (OR, 0.57; P = .001) and ascites (OR, 2.89; P = .01) for mental/cognitive/language impairment at 1 year of age. An unsuccessful hepatoportoenterostomy was predictive of both physical/motor (OR, 4.88; P < .02) and mental/cognitive/language impairment (OR, 4.76; P = .02) at 2 years of age. CONCLUSION: Participants with biliary atresia surviving with native livers after hepatoportoenterostomy are at increased risk for neurodevelopmental delays at 12 and 24 months of age. Those with unsuccessful hepatoportoenterostomy are >4 times more likely to have neurodevelopmental impairment compared with those with successful hepatoportoenterostomy. Growth delays and/or complications indicating advanced liver disease should alert clinicians to the risk for neurodevelopmental delays, and expedite appropriate interventions.
