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 Presentation and Outcomes of Infants With Idiopathic Cholestasis: A Multicenter Prospective Study(Wolters Kluwer, 2021-10-01) Hertel, Paula M.; Hawthorne, Kieran; Kim, Sehee; Finegold, Milton J.; Shneider, Benjamin L.; Squires, James E.; Gupta, Nitika A.; Bull, Laura N.; Murray, Karen F.; Kerkar, Nanda; Ng, Vicky L.; Molleston, Jean P.; Bezerra, Jorge A.; Loomes, Kathleen M.; Taylor, Sarah A.; Schwarz, Kathleen B.; Turmelle, Yumirle P.; Rosenthal, Philip; Magee, John C.; Sokol, Ronald J.; Pediatrics, School of MedicineObjectives: The aim of the study was to determine the frequency and natural history of infantile idiopathic cholestasis (IC) in a large, prospective, multicenter cohort of infants. Methods: We studied 94 cholestatic infants enrolled up to 6 months of age in the NIDDK ChiLDReN (Childhood Liver Disease Research Network) "PROBE" protocol with a final diagnosis of IC; they were followed up to 30 months of age. Results: Male sex (66/94; 70%), preterm birth (22/90 with data; 24% born at < 37 weeks' gestational age), and low birth weight (25/89; 28% born at <2500 g) were frequent, with no significant differences between outcomes. Clinical outcomes included death (n = 1), liver transplant (n = 1), biochemical resolution (total bilirubin [TB] ≤1 mg/dL and ALT < 35 U/L; n = 51), partial resolution (TB > 1 mg/dL and/or ALT > 35 U/L; n = 7), and exited healthy (resolved disease per study site report but without documented biochemical resolution; n = 34). Biochemical resolution occurred at median of 9 months of age. GGT was <100 U/L at baseline in 34 of 83 participants (41%). Conclusions: Frequency of IC and of death or liver transplant was less common in this cohort than in previously published cohorts, likely because of recent discovery and diagnosis of genetic etiologies of severe/persistent cholestasis that previously were labeled as idiopathic. Preterm birth and other factors associated with increased vulnerability in neonates are relatively frequent and may contribute to IC. Overall outcome in IC is excellent. Low/normal GGT was common, possibly indicating a role for variants in genes associated with low-GGT cholestasis-this warrants further study.
