Material economic hardship is associated with adverse 1-year outcomes after pediatric liver transplantation: Prospective cohort results from the multi-center SOCIAL-Tx study.

Pediatric liver transplant outcomes exhibit disparities, necessitating identification of modifiable risk factors to develop targeted interventions. We characterized associations between household material economic hardship (e.g.

Pushing the Limits of In Situ Split Liver Procurement to Overcome Donor Distance and Graft Size Challenges for 8-Week-Old Pediatric Recipient.

Background: Pediatric liver transplantation for small recipients presents significant challenges, particularly in securing suitably sized donor organs. This case report illustrates the feasibility of performing an in situ split procurement in an 18.5-kg toddler, the smallest recorded case in the OPTN database to date, for a critically ill 8-week-old infant recipient.

Optimizing pediatric liver transplantation: Evaluating the impact of donor age and graft type on patient survival outcome.

Background: We examined the combined effects of donor age and graft type on pediatric liver transplantation outcomes with an aim to offer insights into the strategic utilization of these donor and graft options.

Methods: A retrospective analysis was conducted using a national database on 0-2-year-old (N = 2714) and 3-17-year-old (N = 2263) pediatric recipients. These recipients were categorized based on donor age (≥40 vs <40 years) and graft type.

Anti-spike antibody durability after SARS-CoV-2 vaccination in adolescent solid organ transplant recipients.

Background: Adolescent solid organ transplant recipients (aSOTRs) who received three doses of the COVID-19 mRNA vaccine experience high seroconversion rates and antibody persistence for up to 3 months. Long-term antibody durability beyond this timeframe following three doses of the SARS-CoV-2 mRNA vaccine remains unknown. We describe antibody responses 6 months following the third vaccine dose (D3) of the BNT162b2 mRNA vaccination among aSOTRs.

Caregivers' and providers' perspectives of social and medical care after pediatric liver transplant: Results from the multicenter SOCIAL-Tx study.

Disparities exist in pediatric liver transplant (LT). We characterized barriers and facilitators to providing transplant and social care within pediatric LT clinics. This was a multicenter qualitative study.

Considerations for liver transplantation in deoxyguanosine kinase deficiency: A case series and review of the literature.

Background: Deoxyguanosine kinase (DGUOK) deficiency is a rare mitochondrial disorder characterized by early onset liver failure and varying degrees of neurologic dysfunction. Patients typically present during infancy with progressive hepatic dysfunction leading to liver failure, which can precede neurologic deterioration. Outcomes posttransplantation are historically worse than average and the role of liver transplantation remains controversial.

Omicron Infections in Vaccinated Pediatric Solid Organ Transplant Recipients.

SARS-CoV-2 infection during the Omicron period was frequent amongst a cohort of vaccinated pediatric solid organ transplant recipients (pSOTRs) despite robust anti-receptor-binding domain (anti-RBD) antibody response, suggesting poor neutralizing capacity against Omicron subvariants. Breakthrough infections among pSOTRs were overall limited in severity.

Caregiver Perceptions of Social Risk Screening in Pediatric Liver Transplantation: From the Multicenter SOCIAL-Tx Study.

Background: The social determinants of health contribute to adverse post-liver transplant outcomes. Identifying unmet social risks may enable transplant teams to improve long-term outcomes for at-risk children. However, providers may feel uncomfortable asking about household-level social risks in the posttransplant period because they might make their patients/families uncomfortable.

Association of state Medicaid expansion policies with pediatric liver transplant outcomes.

Children from minoritized/socioeconomically deprived backgrounds suffer disproportionately high rates of uninsurance and graft failure/death after liver transplant. Medicaid expansion was developed to expand access to public insurance. Our objective was to characterize the impact of Medicaid expansion policies on long-term graft/patient survival after pediatric liver transplantation.

Resolution of Pruritus in a Child With Alagille Syndrome Treated With Maralixibat for Seven Years: Durable Response and Discontinuation of Other Medications.

Intractable pruritus is one of the most prominent and debilitating features of Alagille syndrome. Maralixibat is the first US Food and Drug Administration-approved drug for the treatment of cholestatic pruritus in children with Alagille syndrome aged 3 months and older. Clinical trials of maralixibat have reported follow-up to 4 years and reported a ≥1-pt reduction using the Itch-Reported Outcome (Observer) (ItchRO[Obs]) instrument (0-4 scale), as this decrease was previously defined as a clinically meaningful improvement in pruritus; participants in clinical trials were expected to be maintained on stable doses of antipruritic agents.

Clinical spectrum and genetic causes of mitochondrial hepatopathy phenotype in children.

Background: Alterations in both mitochondrial DNA (mtDNA) and nuclear DNA genes affect mitochondria function, causing a range of liver-based conditions termed mitochondrial hepatopathies (MH), which are subcategorized as mtDNA depletion, RNA translation, mtDNA deletion, and enzymatic disorders. We aim to enhance the understanding of pathogenesis and natural history of MH.

Methods: We analyzed data from patients with MH phenotypes to identify genetic causes, characterize the spectrum of clinical presentation, and determine outcomes.

An ethical analysis of obesity as a contraindication to pediatric liver transplant candidacy.

Childhood obesity is becoming more prevalent in the United States (US) and worldwide, including among children in need of a liver transplant. Unlike with heart and kidney failure, end-stage liver disease (ESLD) is unique in that no widely available medical technology can re-create the life-sustaining function of a failing liver. Therefore, delaying a life-saving liver transplant for weight loss, for example, is much harder, if not impossible for many pediatric patients, especially those with acute liver failure.

Fractionated plasma N-glycan profiling of novel cohort of ATP6AP1-CDG subjects identifies phenotypic association.

ATP6AP1-CDG is an X-linked disorder typically characterized by hepatopathy, immunodeficiency, and an abnormal type II transferrin glycosylation pattern. Here, we present 11 new patients and clinical updates with biochemical characterization on one previously reported patient. We also document intrafamilial phenotypic variability and atypical presentations, expanding the symptomatology of ATP6AP1-CDG to include dystonia, hepatocellular carcinoma, and lysosomal abnormalities on hepatic histology.

Feasibility of using a patient-reported outcome measure into clinical practice following pediatric liver transplantation: The Starzl Network experience.

Background: Patient-reported outcome measures (PROMs) are not routinely used in clinical care by pediatric liver transplant (LT) teams. The Starzl Network for Excellence in Pediatric Transplantation (SNEPT) assessed feasibility of using a disease-specific Quality of Life (QoL) questionnaire in the ambulatory setting at 10 SNEPT sites.

Methods: A mixed methods feasibility project assessing administration processes, barriers, and user experiences with the Pediatric Liver Transplant Quality of Life (PeLTQL) tool.

Serum biomarkers correlated with liver stiffness assessed in a multicenter study of pediatric cholestatic liver disease.

Background And Aims: Detailed investigation of the biological pathways leading to hepatic fibrosis and identification of liver fibrosis biomarkers may facilitate early interventions for pediatric cholestasis.

Approach And Results: A targeted enzyme-linked immunosorbent assay-based panel of nine biomarkers (lysyl oxidase, tissue inhibitor matrix metalloproteinase (MMP) 1, connective tissue growth factor [CTGF], IL-8, endoglin, periostin, Mac-2-binding protein, MMP-3, and MMP-7) was examined in children with biliary atresia (BA; n = 187), alpha-1 antitrypsin deficiency (A1AT; n = 78), and Alagille syndrome (ALGS; n = 65) and correlated with liver stiffness (LSM) and biochemical measures of liver disease. Median age and LSM were 9 years and 9.
