Indications for pediatric lung transplantation in 2025: A new era.

The year 2025 marks an important landmark: almost 40 years since the first pediatric lung transplant (LTX), over 3-5 years since the availability of elexacaftor/tezacaftor/ivacaftor in several countries, and 5-10 years since striking shifts were reported in the diagnoses that accounted for pediatric LTX. We review historic indications for pediatric LTX, highlighting shifts in these over time, and analyze data from the ISHLT International Thoracic Organ Transplant Registry, United Network of Organ Sharing, Canadian Cystic Fibrosis (CF) Registry, and other databases up to the present day. Currently, pediatric CF-related LTX cases are at record lows in many countries.

Post-operative management of children after lung transplantation.

Post-operative care for children and adolescents who undergo lung transplantation is a challenge because of the potential for numerous complications during this period, which can considerably impact the short- and long-term outcomes. The immediate post-operative phase is particularly critical, and complications are frequent; therefore, knowledge, early recognition, and appropriate treatment of these complications are imperative and can only be achieved through close collaboration between a wide range of medical specialties. The aim of this review is to provide an abbreviated overview of the optimal post-operative management of children in an intensive care unit, as well as to describe frequently occurring complications and their treatment.

Beyond Borders: International Immunosuppression Practices in Pediatric Lung Transplantation.

Introduction: Current recommendations for lung transplantation immunosuppression do not explicitly target children, and many pharmacotherapies used in pediatrics are extrapolated from adults.

Methods: Data were collected from an anonymous survey distributed to International Pediatric Lung Transplant Collaborative (IPLTC) members from November 2023 to February 2024. Eligible participants included pediatric lung transplant physicians, pharmacists, or others with expertise in their lung transplant center's protocols.

Outcomes of lung transplantation in cystic fibrosis.

Purpose Of Review: Lung transplantation (LTX) has transformed care for people with cystic fibrosis (pwCF) suffering from advanced cystic fibrosis lung disease (ACFLD), and it has evolved into an accepted therapy for patients with ACFLD across all ages. We review cystic fibrosis as a major indication for LTX, particularly highlighting outcomes including survival, a changing landscape over time, and factors affecting sequelae following LTX in cystic fibrosis.

Recent Findings: Although some populations such as those undergoing lung retransplantation exhibit inferior posttransplant outcomes, LTX for pwCF provides an excellent long-term survival that has significantly improved over time, likely due to specialized cystic fibrosis center care and recognition of common comorbidities in pwCF post-LTX.

Worldwide organ allocation systems for pediatric lung transplantation.

Pediatric lung transplantation (LTX) remains limited by the scarcity of small donor lungs, particularly in less populated parts of the world. Optimal organ allocation, including the prioritization and ranking of pediatric LTX candidates, and the appropriate matching of pediatric donors to recipients have been crucial elements in improving pediatric LTX outcomes. We aimed to elucidate the various pediatric lung allocation practices worldwide.

Monitoring practices of chronic lung allograft dysfunction in pediatric lung transplantation.

Introduction: Chronic lung allograft dysfunction (CLAD) continues to negatively impact the survival of pediatric lung transplant (LTx) recipients. Current consensus guidelines are adult-focused. We sought to examine CLAD detection and monitoring practices at pediatric LTx programs.

The changing landscape of pediatric lung transplantation.

There has been a shift over decades in the diagnostic indications for lung transplantation in children; in particular, there has been a reduction in the proportion of pediatric cystic fibrosis (CF) patients undergoing lung transplantation early in life, and more transplants occurring in other diagnostic groups. Here, we examine trends in pediatric lung transplantation with regards to indications by analyzing data from the United Network of Organ Sharing, the International Society for Heart and Lung Transplantation Thoracic Transplant Registry, and other sources. Over the past two years, there has been a precipitous decline in both the number of transplants due to CF and the proportion of CF cases relative to the total number of transplants, likely not solely due to the COVID-19 pandemic.

Alterations in the immune phenotype of thymectomized children and the development of atopic disorders after heart transplantation.

Background: Atopic disorders are more common in children after heart transplant (HTx). We hypothesized that HTx at an early age and thymus excision (TE) affect development of T and B cells, especially regulatory T cells (Tregs), which help maintain tolerance.

Methods: In this single-center study including 24 patients transplanted between 2013 and 2018, we investigated lymphocyte patterns in relation to these factors using flow cytometry.

Bilateral leg swelling as the presenting symptom of Löfgren syndrome in a paediatric patient: a rare presentation of a rare paediatric disease.

A 17-year-old previously healthy man presented with a 4-week history of progressive bilateral leg swelling with discomfort and erythema, but no signs of arthritis or erythema nodosum. An incidental finding of a query pulmonary nodule on chest X-ray prompted chest CT for further evaluation, revealing bilateral hilar and mediastinal lymphadenopathy. The patient then underwent endobronchial ultrasound and transbronchial needle aspiration biopsies of mediastinal lymph nodes.

Rare broncho-pulmonary arterial fistula in a healthy 9-year-old girl.

A 9-year-old previously well girl presented with multiple episodes of large volume haemoptysis and right sided consolidation. She continued to have haemoptysis despite intravenous antibiotics. CT chest suggested a right mainstem endobronchial lesion; this was not seen on bronchoscopy where an extensive blood clot was removed.

Comparison of a handheld turbine spirometer to conventional spirometry in children with cystic fibrosis.

Background: In pediatric cystic fibrosis (CF) ambulatory care, handheld spirometry in individual clinic rooms would improve patient flow and potentially reduce patient-to-patient contact. A validation study was conducted to examine the accuracy of an entirely handheld turbine spirometer vs a standard laboratory device in pediatric CF patients.

Methods: Spirometric data were obtained from 76 CF patients aged less than 18 years in the ambulatory setting using the Micro Loop Spirometer (CareFusion) and compared to same-day data from conventional laboratory spirometry.

Allergies and autoimmune disorders in children after heart transplantation.

Pediatric heart transplantation requires lifelong immune suppression and may require thymectomy, both of which alter T-cell repertoires. We hypothesized that atopic and autoimmune diseases are more common in pediatric heart transplant patients than the general population, and that transplantation in early childhood increases the risk of development or worsening of atopic or autoimmune disease. A cross-sectional single-center study including 21 heart transplant patients aged ≤18 years was conducted.

Focus on pediatric intentional trauma.

Background: Based on our previous study, pediatric intentional trauma injuries with Injury Severity Scores (ISS) ≥ 12 were more commonly observed in the urban than the rural setting (15.2% vs. 5.
