Lung transplantation in children. Specific aspects

Area of Science:

• Pediatric pulmonology
• Thoracic surgery
• Transplantation medicine

Background:

• Lung transplantation is an established therapy for pediatric end-stage lung disease.
• Spain has performed 114 pediatric lung transplants since 1996, representing 3.9% of total transplants.
• Cystic fibrosis is the primary indication in adolescents (70-80%), while interstitial lung disease and pulmonary hypertension are common in infants.

Purpose of the Study:

• To review the outcomes and challenges of pediatric lung transplantation.
• To highlight the indications, methods, complications, and survival rates in children undergoing lung transplants.

Main Methods:

• Sequential double lung transplantation, often utilizing extracorporeal circulation, is the standard procedure.
• Monitoring and follow-up present unique challenges in pediatric patients, particularly infants, due to difficulties in assessing lung function and performing biopsies.
• Specific pediatric complications include post-transplant lymphoproliferative syndrome and increased severity of respiratory viral infections.

Main Results:

• Pediatric lung transplantation leads to significant improvements in quality of life, with 88% of children experiencing no activity limitations after 3 years.
• International Society for Heart & Lung Transplantation (ISHLT) registry data show 5-year survival at 54% and 10-year survival around 35%.

Conclusions:

• Lung transplantation is a crucial therapeutic option for pediatric end-stage lung disease, comparable to adult outcomes.
• Despite challenges in monitoring and specific complications, the procedure substantially enhances long-term quality of life for pediatric recipients.
