Aim: To examine and characterize post-transplant eosinophilic gastrointestinal disorders (PTEGID) and post-transplant lymphoproliferative disorder (PTLD) in pediatric liver transplant recipients., Methods: This is a single center retrospective study of all liver transplant recipients aged 0-18 years from 1999 to 2019 who received tacrolimus as their primary immunosuppressant. Demographic data and clinical/laboratory data including PTEGID, PTLD, liver transplant types, Epstein-Barr virus status, and blood eosinophil count were reviewed. Analysis was done with logistic regression and Mann-Whitney U test., Results: Ninety-eight pediatric liver transplant recipients were included with median age at transplantation of 3.3 years (IQR: 1.1-9.3). The major indication for transplantation was biliary atresia, 51 (52%) cases. Eight (8%) children had PTLD and 14 (14%) had PTEGID. Receiving liver transplantation at an age of ≤1 year was associated with developing PTEGID (OR = 11.9, 95% CI = 3.5-45.6, p < 0.001). Additionally, eosinophilic count of ≥500/μL was associated with having PTLD (OR = 10.7, 95% CI = 1.8-206.0, p = 0.030) as well as having at least one liver rejection (OR = 2.8, 95% CI = 1.2-7.0, p = 0.024). The frequency of food-induced anaphylaxis significantly increased post-transplantation (p = 0.023)., Conclusions: PTEGID and PTLD are common in this cohort and are associated with certain risk factors that help screen children to improve recipient survival. Further studies are needed to evaluate the clinical benefits of these findings., (Copyright © 2021 Elsevier B.V. All rights reserved.)

Hepatitis E virus (HEV) is an emerging cause of viral hepatitis among immunocompromised individuals in developed countries. Yet the diagnosis of HEV infection in the United States remains challenging, because of the variable sensitivity and specificity of currently available tests, and the lack of a US Food and Drug Administration-approved test. We report a case of multiple discordant HEV serology results in a pediatric liver transplant recipient with idiopathic hepatitis, and review the challenges to diagnosis of HEV infection in the United States., (© 2015 John Wiley & Sons A/S.

An 18-month-old female status post-orthotopic liver transplant for biliary atresia presented nine months after transplant with severe diarrhea and intolerance of feeds. She was found to have a PLE as evidenced by a low serum albumin and a persistent elevation of fecal A1AT. Investigation eventually revealed that the cause of the PLE was a stricture at the anastomosis site between the hepatic vein and inferior cava, supported by resolution of the PLE after venoplasty of the stricture. The patient has subsequently required several repeat venoplasties for recurrence of her symptoms correlating with recurrence of the stricture. This is a very rare presentation of hepatic venous outflow obstruction. Moreover, normal duplex ultrasound imaging of liver vasculature and her unusual presentation led to a delay in her diagnosis highlighting the need for an increased index of suspicion., (© 2012 John Wiley & Sons A/S.)

Little data concerning hospital charges and long-term outcomes of LDLT in North American children according to transplant indications have been published. To compare outcomes of patient and graft survival and healthcare charges for LDLT for those with BA vs. other diagnoses (non-BA). A retrospective review of 52 children receiving 53 LDLT (38 BA and 14 non-BA) from 1992 to 2010 at our institution was performed. One-, five-, and 10-yr patient and graft survival data were comparable to national figures reported to UNOS. Average one-yr charges for recipients and donors were $242 849 for BA patients and $183 614 for non-BA (p = 0.074). BA patients were 1.23 ± 1.20 yr of age vs. 4.25 ± 5.02 for non-BA, p = 0.045. Examination of the total population of patients who were alive in 2010 in five chronological groupings showed that the crude five-yr survival rates were 1992-1995: 9/11 (82%); 1995-1997: 6/10 (60%); 1997-1999: 8/10 (80%); 1999-2001: 9/10 (90%); and 2001-2003: 7/7 (100%). Thus, examination of the clinical and financial data together over the entire period of the transplant program suggests that the dramatic improvement in patient survival was accomplished without a dramatic increase in indexed charges. All 53 donors survived, and only 10% had complications requiring hospitalization. LDLT in children results in excellent outcomes for patients and donors. Ways to lower costs and maximize graft outcome should be investigated., (© 2012 John Wiley & Sons A/S.)
