[Prognostic factors in pediatric liver transplantation. Multivariate analysis].

Area of Science:

• Pediatric Surgery
• Hepatology
• Transplantation Immunology

Context:

• Pediatric liver transplantation (PLT) is a complex procedure with varying outcomes.
• Understanding risk factors is crucial for improving graft and patient survival rates.
• This study analyzes a large cohort of PLT over 15 years to identify key predictors of success.

Purpose:

• To identify independent risk factors associated with graft and patient survival in pediatric liver transplants.
• To analyze the impact of pretransplant status, surgical techniques, and donor conditions on PLT outcomes.
• To determine predictors for graft loss and patient mortality in a pediatric liver transplant cohort.

Summary:

• Multivariate analysis identified UNOS 1 status, recipient age under 3 years, transplantation for autoimmune hepatitis, and transplant era as independent predictors of graft loss.
• Independent factors influencing patient survival included receiving more than one graft, recipient age under 3 years, and transplant era.
• Graft survival was influenced by 11 variables, while patient survival was impacted by recipient age, transplant for autoimmune hepatitis, and transplant era.

Impact:

• Liver transplantation in very young children (<3 years) is associated with a significantly increased risk of graft loss and mortality.
• Hospital experience and expertise in pediatric liver transplantation are critical for improving patient and graft survival, especially in high-risk populations.
• These findings can inform clinical decision-making and resource allocation to optimize outcomes for pediatric liver transplant recipients.
