(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.

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.

The prevalence of multidrug-resistant Gram-negative infections, particularly carbapenem-resistant strains, has become a significant global health concern. Ceftazidime–avibactam (CZA) has emerged as a promising treatment option. However, data on its efficacy and safety in children are scarce, necessitating further investigation. We conducted a descriptive case series at a tertiary hospital in Spain from February 2019 to January 2022. Pediatric patients (<16 years) treated with CZA for confirmed or suspected multidrug-resistant Gram-negative infections were included. The clinical and microbiological characteristics, treatment approaches, and outcomes were examined. Eighteen children received CZA treatment. All had complex chronic conditions, with the most frequent underlying main diseases being liver transplantation (n = 8) and biliary atresia (n = 4). The predominant type of infection for which they received CZA was intra-abdominal infection caused or suspected to be caused by OXA-48-producing Klebsiella pneumoniae. CZA was generally well tolerated. Within the first month of starting CZA therapy, two patients died, with one case directly linked to the infection’s fatal outcome. Some patients needed repeated courses of therapy due to recurrent infections, yet no resistance development was noted. In summary, the use of CZA showed effectiveness and safety, while the lack of resistance development highlights CZA’s potential as a primary treatment option against OXA-48-producing infections.

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.

La incidencia de los tumores hepáticos durante la infancia es baja. De entre los tumores benignos, el más frecuente es el hemangioma, mientras que el hepatoblastoma y el hepatocarcinoma son los tumores malignos más frecuentes. En la mayoría de los casos, se va a detectar el tumor tras una ecografía, bien tras palpación de una hepatomegalia o bien en el contexto de un examen rutinario. El hemangioma presenta un ciclo natural de crecimiento y posterior involución, por lo que el tratamiento solo está indicado en aquellos casos sintomáticos. En los casos de un hepatoblastoma o hepatocarcinoma, la curación de la enfermedad pasa por la resección completa del tumor y tratamiento con quimioterapia adyuvante. La supervivencia de los niños con tumores hepáticos, especialmente en el caso del hepatoblastoma, ha mejorado significativamente tras la introducción de pautas de quimioterapia efectivas y definición de estrategias quirúrgicas, incluyendo el trasplante hepático, apropiadas en cada caso.
