Prognosis of Children Undergoing Liver Transplantation: A 30-Year European Study.

OBJECTIVES: The European Liver Transplant Registry has been collecting data on virtually all pediatric liver transplant (PLT) procedures in Europe since 1968. We analyzed patient outcome over time and identified parameters associated with long-term patient outcome. METHODS: Participating centers and European organ-sharing organizations provided retrospective data to the European Liver Transplant Registry. To identify trends, data were grouped into consecutive time spans: era A: before 2000, era B: 2000 to 2009, and the current era, era C: since 2010. RESULTS: From June 1968 until December 2017, 16 641 PLT were performed on 14 515 children by 133 centers. The children <7 years of age represented 58% in era A, and 66% in the current era (P <.01). The main indications for PLT were congenital biliary diseases (44%) and metabolic diseases (18%). Patient survival at 5 years is currently 86% overall and 97% in children who survive the first year after PLT. The survival rate has improved from 74% in era A to 83% in era B and 85% in era C (P <.0001). Low-volume centers (<5 PLT/year) represented 75% of centers but performed only 19% of PLT and were associated with a decreased survival rate. In the current era, however, survival rates has become irrespective of volume. Infection is the leading cause of death (4.1%), followed by primary nonfunction of the graft (1.4%). CONCLUSIONS: PLT has become a highly successful medical treatment that should be considered for all children with end-stage liver disease. The main challenge for further improving the prognosis remains the early postoperative period.

Social Resources for Transplanted Children and Families in European Union Hospitals of ERN TransplantChild.

Social well-being is an intrinsic part of the current concept of health. In the context of chronic disease, there are many challenges we face in order to provide social well-being to patients and their families, even more if we talk about rare diseases. TransplantChild, a European Reference Network (ERN) in paediatric transplantation, works to improve the quality of life of transplanted children. It is not possible to improve the quality of life if the human and material resources are not available. With this study, we want to identify the economic aids, facilities, services, and financed products that are offered to families in different European centres. We also want to find out who provides these resources and the accessibility to them. We designed an ad hoc survey using the EU Survey software tool. The survey was sent to representatives of the 26 ERN members. In this article we present the results obtained in relation to two of the aspects analysed: long-term financial assistance and drugs, pharmaceuticals and medical devices. Some resources are equally available in all participating centres but there are significant differences in others, such as education aids or parapharmacy product financing. A local analysis of these differences is necessary to find feasible solutions for equal opportunities for all transplanted children in Europe. The experience of centres that already provide certain solutions successfully may facilitate the implementation of these solutions in other hospitals.

ABO Incompatible Liver Transplantation in Children: A 20 Year Experience from Centres in the TransplantChild European Reference Network.

An increasing number of AB0-incompatible (AB0i) liver transplantations (LT) are being undertaken internationally in recent years due to organ shortages and the need for urgent transplantation. The aim of our study was establish the value of ABOi LT from available retrospective results of AB0i pediatric liver transplantations performed in European reference centers now belonging to the TransplantChild, European Reference Network (ERN). Data from medical records were analyzed, including demographic data, diagnosis, urgency of transplantation, time on the waiting list, PELD/MELD score, desensitization procedures, immunosuppression, selected post-transplant complications, and patient and graft survival. A total of 142 patients (pts) with transplants between 1986 and 2018 in 8 European transplant centers were included in the study. The indications for liver transplantation were: cholestatic diseases in 62 pts, acute liver failure in 42 pts, and other conditions in the remaining 38 pts. Sixty-six patients received grafts from living donors, and seventy-six received grafts from deceased donors. Both patient and graft survival were significantly affected by deceased donor type, urgent transplantation, and the development of vascular complications. In the multivariate analysis, vascular complications had a negative impact on patient and graft survival, while a longer time from the first AB0i LT in the study showed better results, suggesting an international learning experience. In conclusion, we believe that AB0i LT in children is now a safe procedure that may be adopted more readily in children.

Current Practices on Diagnosis, Prevention and Treatment of Post-Transplant Lymphoproliferative Disorder in Pediatric Patients after Solid Organ Transplantation: Results of ERN TransplantChild Healthcare Working Group Survey.

(1) Background: Post-transplant lymphoproliferative disease (PTLD) is a significant complication of solid organ transplantation (SOT). However, there is lack of consensus in PTLD management. Our aim was to establish a present benchmark for comparison between international centers and between various organ transplant systems and modalities; (2) Methods: A cross-sectional questionnaire of relevant PTLD practices in pediatric transplantation was sent to multidisciplinary teams from 17 European center members of ERN TransplantChild to evaluate the centers' approach strategies for diagnosis and treatment and how current practices impact a cross-sectional series of PTLD cases; (3) Results: A total of 34 SOT programs from 13 European centers participated. The decision to start preemptive treatment and its guidance was based on both EBV viremia monitoring plus additional laboratory methods and clinical assessment (61%). Among treatment modalities the most common initial practice at diagnosis was to reduce the immunosuppression (61%). A total of 126 PTLD cases were reported during the period 2012-2016. According to their histopathological classification, monomorphic lesions were the most frequent (46%). Graft rejection after PTLD remission was 33%. Of the total cases diagnosed with PTLD, 88% survived; (4) Conclusions: There is still no consensus on prevention and treatment of PTLD, which implies the need to generate evidence. This might successively allow the development of clinical guidelines.

Hemocromatosis neonatal: tratamiento con inmunoglobulinas en la gestación / Neonatal haemochromatosis: treatment with immunoglobulins in pregnancy

La hemocromatosis neonatal (HN) es una enfermedad hepática grave neonatal con alta tasa demortalidad y recurrencia. Se postulaun origen a lo inmunitario, resultado de la presencia de un anticuerpo materno aún por determinar que interfiera con el metabolismo férrico fetal. En esta teoría se basa el tratamiento materno con inmunoglobulinas por vía intravenosa en gestaciones sucesivas. Describimos el caso de una paciente con un hijo anterior diagnosticado y fallecido por HN, que tratamos en la siguiente gestación con inmunoglobulinas por vía intravenosa. Es el primer caso descrito en España y demuestra el éxito de la terapia, tal como describe la literatura científica (AU)

Neonatal hemochromatosis is a severe neonatal liver disease with a high mortality and recurrence rate. In theory, it is a gestational alloimmune disease due to there being maternal antibodies against fetal hepatic metabolism. On the basis of this hypothesis, the administration of intravenous immunoglobulin has been reported as a succesful treatment during subsequent pregnancies. Here, we describe the first case of this treatment in Spain which confirms the data available in the literature (AU)

[Wilson's disease: forms of presentation in childhood]. / La enfermedad de Wilson: formas de presentación en la infancia.

Wilson's disease can manifest with symptoms of liver disease or neuropsychiatric disorders in children and adults. This autosomal recessive disorder is caused by a copper metabolism disorder due to a mutation in the ATP7B transporter. Excessive amounts of copper accumulate in the body due to inhibition of the release of copper into bile. Because effective treatment is available, recognizing this disease in presymptomatic or early stages, when it can be reversed, is highly important. Diagnosis is often easy but the available tests (measurement of ceruloplasmin, and blood, urinary and liver copper levels) can be misleading. There is no single test with 100% sensitivity in screening nor do any of the tests, when used alone, provide 100% specificity. Diagnosis is currently based on the combination of clinical findings and the results of laboratory tests. Genetic study, with a finding of mutations in the two alleles of the ATP7B gene, is still not a rapid and easily available alternative and the absence of these mutations does not rule out the possible presence of other mutations not yet described.

La enfermedad de Wilson: formas de presentación en la infancia / Wilson’s disease: forms of presentation in childhood

La enfermedad de Wilson puede manifestarse por síntomas de hepatopatía o trastornos neuropsiquiátricos, en niños y adultos. La causa es un trastorno en el metabolismo del cobre, por mutación en el transportador ATP7B, de herencia recesiva. Se produce una acumulación de cobre por la imposibilidad de eliminar el exceso mediante su excreción en la bilis. Hay un tratamiento eficaz, por lo que es de gran importancia reconocer la enfermedad preferiblemente en estadios tempranos de lesión o presintomáticos, susceptibles de ser completamente reversibles. El diagnóstico es fácil en muchos pacientes, pero las pruebas disponibles (ceruloplasmina, cobre en sangre, cupruria, cobre en tejido hepático) no siempre son inequívocas. No hay ninguna prueba que de forma aislada sea totalmente sensible para el cribado, y ninguna prueba es totalmente específica. La combinación de los hallazgos clínicos y las pruebas analíticas son actualmente la base para el diagnóstico. El estudio genético, con la demostración de mutaciones en los 2 alelos del gen ATP7B, todavía no es una alternativa accesible con rapidez, y la ausencia de las mutaciones ya identificadas no excluye la posibilidad de que el paciente tenga otras no descritas
