Status of 18 pediatric cases of COVID-19 post-liver transplantation.

We describe our experience with COVID-19 after pediatric liver transplantation (LT). In this study, we analyzed 18 of 196 children who contracted COVID-19 after LT during outpatient follow-up at our department. The severity of COVID-19 was mild in all cases, and all cases were cured without sequelae. COVID-19 after LT in children may have a high risk of severe disease. However, the disease is relatively mild and may be cured.Copyright © 2022 The Japan Society of Hepatology.

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. Iterative processes sought stakeholder feedback across four phases (Pilot, Extended Pilot, Development of a Mobile App PeLTQL version, and Pilot App use). RESULTS: A total of 149 patient-parent dyads completed the PeLTQL during LT clinic follow-up. Clinicians, parents, and patients evaluated and reported on feasibility of operationalization. Only two of 10 SNEPT sites continued PeLTQL administration after the initial two pilot phases. Reasons include limited clinical time and available personnel aggravated by the COVID-19 pandemic. In response, a mobile application version of the PeLTQL was initiated. Providing PeLTQL responses electronically was "very easy" or "easy" as reported by 96% (22/23) parents. CONCLUSIONS: Administration of a PROM into post-pediatric LT clinical care was feasible, but ongoing utilization stalled. Use of a mobile app towards facilitating completion of the PeLTQL outside of clinic hours may address the time and work-flow barriers identified.

Successful pediatric liver transplantation case with a positive SARS-CoV-2 test at the time of transplant.

AIM: We report a successful liver transplantation (LT) in a child with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. CASE PRESENTATION: A 3-year-old female patient with decompensated cirrhosis due to Alagille syndrome underwent a split LT with a left lateral segment graft. She had a history of SARS-CoV-2 infection 4 months before LT. She was exposed to SARS-CoV-2 after the decision for organ acceptance. We repeatedly confirmed the negative SARS-CoV-2 test by polymerase chain reaction (PCR) before LT. Liver transplantation was carried out in the negative pressure operational theater with full airborne, droplet, and contact precautions as the patient was considered to be within the incubation period of SARS-CoV-2. The SARS-CoV-2 PCR test became positive in the nasopharyngeal swab specimen at the operation. Remdesivir, the antiviral treatment, was held off due to potential hepatotoxicity and no exacerbation of COVID-19. She received tacrolimus and low-dose steroids per protocol. She remained SARS-CoV-2 positive on postoperative days (PODs) 1, 2, and 5. The presence of antibodies for SARS-CoV-2 at LT was confirmed later. On POD 53, she was discharged without any symptomatic infection. CONCLUSION: This case demonstrated that a positive SARS-CoV-2 result was not an absolute contraindication for a life-saving LT. Liver transplantation could be safely performed in a pediatric patient with asymptomatic COVID-19 and S-immunoglobulin G antibodies for SARS-CoV-2.

A new chapter in an evolving pandemic: Successful pediatric liver transplantation with SARS-CoV-2+ donors.

BACKGROUND: Amid a viral pandemic with poorly understood transmissibility and pathogenicity in the pediatric patient, we report the first pediatric liver transplants utilizing allografts from SARS-CoV-2+ donors. METHODS: We describe the outcomes of two pediatric liver transplant recipients who received organs from SARS-CoV-2 nucleic acid test-positive (NAT+) donors. Data were obtained through the respective electronic medical record system and UNet DonorNet platform. RESULTS: The first donor was a 3-year-old boy succumbing to head trauma. One of four nasopharyngeal (NP) swabs and 1 of 3 bronchoalveolar lavage (BAL) NAT tests demonstrated SARS-CoV-2 infection before organ procurement. The second donor was a 16-month-old boy with cardiopulmonary arrest of unknown etiology. Three NAT tests (2 NP swab/1 BAL) prior to procurement failed to detect SARS-CoV-2. The diagnosis was made when the medical examiner repeated 2 NP swab NATs and an archive plasma NAT, all positive for SARS-CoV-2. Both 2-year-old recipients continue to do well 8 months post-transplant, with excellent graft function and no evidence of SARS-CoV-2 transmission. CONCLUSIONS: This is the first report to describe successful pediatric liver transplantation from SARS-CoV-2+ donors. These data reinforce the adult transplant experience and support the judicious use of SARS-CoV-2+ donors for liver transplantation in children. With SARS-CoV-2 becoming endemic, the concern for donor-derived viral transmission must now be weighed against the realized benefit of life-saving transplantation in the pediatric population as we continue to work toward donor pool maximization.

Impact of COVID-19 Infection on Children and Adolescents after Liver Transplantation in a Latin American Reference Center.

BACKGROUND: The COVID-19 infection has received the attention of the scientific community due to its respiratory manifestations and association with evolution to severe acute respiratory syndrome (SARS-CoV-2). There are few studies characterizing SARS-CoV-2 in pediatric immunocompromised patients, such as liver transplanted patients. The aim of this study was to analyze the outcomes of the largest cohort of pediatric liver transplant recipients (PLTR) from a single center in Brazil who were infected with COVID-19 during the pandemic. METHODS: Cross-sectional study. PRIMARY OUTCOMES: COVID-19 severity. The Cox regression method was used to determine independent predictors associated with the outcomes. Patients were divided into two groups according to the severity of COVID-19 disease: moderate-severe COVID and asymptomatic-mild COVID. RESULTS: Patients categorized as having moderate-severe COVID-19 were younger (12.6 months vs. 82.1 months, p = 0.03), had a higher prevalence of transplantation from a deceased donor (50% vs. 4.3%, p = 0.02), and had a higher prevalence of COVID infection within 6 months after liver transplantation (LT) (75% vs. 5.7%, p = 0.002). The independent predictor of COVID-19 severity identified in the multivariate analysis was COVID-19 infection <6 months after LT (HR = 0.001, 95% CI = 0.001-0.67, p = 0.03). CONCLUSION: The time interval of less than 6 months between COVID-19 infection and LT was the only predictor of disease severity in pediatric patients who underwent liver transplantation.

Decreased access to pediatric liver transplantation during the COVID-19 pandemic.

BACKGROUND: The COVID-19 pandemic has affected all aspects of the US healthcare system, including liver transplantation. The objective of this study was to understand national changes to pediatric liver transplantation during COVID-19. METHODS: Using SRTR data, we compared waitlist additions, removals, and liver transplantations for pre-COVID-19 (March-November 2016-2019), early COVID-19 (March-May 2020), and late COVID-19 (June-November 2020). RESULTS: Waitlist additions decreased by 25% during early COVID-19 (41.3/month vs. 55.4/month, p < .001) with black candidates most affected (p = .04). Children spent longer on the waitlist during early COVID-19 compared to pre-COVID-19 (140 vs. 96 days, p < .001). There was a 38% decrease in liver transplantations during early COVID-19 (IRR 0.62, 95% CI 0.49-0.78), recovering to pre-pandemic rates during late COVID-19 (IRR 1.03, NS), and no change in percentage of living and deceased donors. White children had a 30% decrease in overall liver transplantation but no change in living donor liver transplantation (IRR 0.7, 95% CI 0.50-0.95; IRR 0.96, NS), while non-white children had a 44% decrease in overall liver transplantation (IRR 0.56, 95% CI 0.40-0.77) and 81% decrease in living donor liver transplantation (IRR 0.19, 95% CI 0.02-0.76). CONCLUSIONS: The COVID-19 pandemic decreased access to pediatric liver transplantation, particularly in its early stage. There were no regional differences in liver transplantation during COVID-19 despite the increased national sharing of organs. While pediatric liver transplantation has resumed pre-pandemic levels, ongoing racial disparities must be addressed.

Liver transplant in a recently COVID-19 positive child with hepatoblastoma.

We describe the successful pediatric liver transplant for unresectable hepatoblastoma in a 4-year-old male with COVID-19 prior to transplant. The first negative NP swab was documented 1 month after initial diagnosis, when SARS-CoV-2 antibodies were also detected. The patient was actively listed for liver transplant after completing four blocks of a SIOPEL-4 based regimen due to his PRETEXT IV disease which remained unresectable. Following three additional negative NP swabs and resolution of symptoms for 4 weeks, he underwent a whole-organ pediatric liver transplant. COVID-19 positivity determined via NP swab SARS-CoV-2 real-time RT-PCR (Hologic Aptima SARS-CoV-2 RT-PCR assay). IgG and IgM total SARS- CoV-2 antibodies detected by Ortho Clinical Diagnostics VITROS® Immunodiagnostics Products Anti-SARS-CoV-2 Test. Patient received standard prednisone and tacrolimus-based immunosuppression without induction therapy following transplant. Post-transplant course was remarkable for neutropenia and thrombocytopenia, with discharge home on post-transplant day #11. Surveillance tests have remained negative with persistent SARS-CoV-2 IgG antibodies at 6 weeks after transplant. We describe one of the earliest, if not the first case of liver transplant following recent recovery from COVID-19 in a pediatric patient with a lethal malignant liver tumor. A better understanding of how to balance the risk profile of transplant in the setting of COVID-19 with disease progression if transplant is not performed is needed. We followed existing ASTS guidelines to document clearance of the viral infection and resolution of symptoms before transplant. This case highlights that pediatric liver transplantation can be safely performed upon clearance of COVID-19.

Awareness and concerns about novel coronavirus disease 2019 (COVID-19) among parents of pediatric liver transplant recipients.

OBJECTIVES: Pediatric transplant recipients may be at increased risk of developing serious infections due to COVID-19. We undertook a web-based survey among parents of post-liver transplant pediatric patients to assess knowledge and concerns regarding COVID-19 pandemic and impact of social media on them. METHODS: This cross-sectional online survey was conducted between March 21 and March 26, 2020. A 19-item questionnaire was sent to 172 parents of post-liver transplant children. RESULTS: 106 (62%) of parents responded. Median time since transplant was 31 (12-52) months. The majority of parents had good understanding regarding symptomatology and routes of transmission. Only 27% were aware of feco-oral transmission, and 34% knew about gastrointestinal symptoms of COVID-19. 100% of parents understood concept of social distancing, and 70% knew that asymptomatic individuals can transmit the virus. Television followed by newspapers was the main source of their information, though over 40% claim to regularly receive information through social media. 87% would consult their doctor if the child had flu-like symptoms rather than modify immunosuppression or try alternative medications. Parental concerns mainly revolved around early recognition of symptoms, queries on unconventional treatments circulating over social media, and supply of medications during the lockdown period. CONCLUSIONS: The majority of parents had basic understanding of COVID-19 pandemic. Social media appeared to be an important source of information. Results from this survey helped us in modifying patient care protocols to ensure continuity of care while maintaining social distancing.
