Item Extrahepatic anomalies in infants with biliary atresia: results of a large prospective North American multicenter study(Wiley, 2013-11) Schwarz, Kathleen B.; Haber, Barbara H.; Rosenthal, Philip; Mack, Cara L; Moore, Jeffrey; Bove, Kevin E.; Bezerra, Jorge A.; Karpen, Saul J.; Kerkar, Nanda; Shneider, Benjamin L.; Turmelle, Yumirle P.; Whitington, Peter F.; Molleston, Jean P.; Murray, Karen F.; Ng, Vicky L.; Romero, René; Wang, Kasper S.; Sokol, Ronald J.; Magee, John C.; Pediatrics, School of MedicineBackground and aims The etiology of biliary atresia (BA) is unknown. Given that patterns of anomalies might provide etiopathogenetic clues, we utilized data from the North American Childhood Liver Disease Research and Education Network to analyze patterns of anomalies in infants with BA. Methods Two hundred eighty-nine infants who were enrolled into the prospective database prior to surgery at any of 15 centers participating were evaluated. Results Group 1 was non-syndromic, isolated BA (without major malformations) (n = 242, 84 %), Group 2 was BA and at least one malformation considered major as defined by the National Birth Defects Prevention Study but without laterality defects (n = 17, 6%). Group 3 was syndromic, with laterality defects (n = 30, 10%). In the population as a whole, anomalies (either major or minor) were most prevalent in the cardiovascular (16%) and gastrointestinal (14%) systems. Group 3 patients accounted for the majority of subjects with cardiac, gastrointestinal and splenic anomalies. Group 2 subjects also frequently displayed cardiovascular (71%) and gastrointestinal (24 %) anomalies; interestingly this group had genitourinary anomalies more frequently (47%) compared to Group 3 subjects (10%). Conclusions This study identified a group of BA (Group 2) that differed from the classical syndromic and non-syndromic groups and that was defined by multiple malformations without laterality defects. Careful phenotyping of the patterns of anomalies may be critical to the interpretation of both genetic and environmental risk factors associated with BA, allowing new insight into pathogenesis and/or outcome.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.
