ObjectivesThe survival benefit of lung transplantation (LTx) for cystic fibrosis (CF) patients is well demonstrated. We aim to compare children and adult CF recipients to assess whether there are differences in survival and clinical outcomes, and to identify risk factors for mortality.MethodsA retrospective analysis of 442 consecutive LTx performed at our institution in a 20-year period was conducted. CF patients were distributed into two groups: children (age <18 years) and adults (age ≥18 years). Donor and recipient general demographic data, perioperative and postoperative factors including 30-day mortality, survival, primary graft dysfunction (PGD), complications, acute rejection (AR) and chronic lung allograft dysfunction (CLAD) were analysed and compared between groups. Univariable, Kaplan-Meier and Cox regression analyses were performed.ResultsThe study group included 120 consecutive CF patients: 50 children (13 ± 3 years) and 70 adults (25 ± 6 years) undergoing 111 bilateral, 4 lobar, 4 combined and 1 unilateral LTx. Comparative analysis (children versus adults): survival (overall; 5, 10 and 15 years) 57, 45, 35% vs 67, 55, 43% (P = 0.32); survival (1-year survivors; 5, 10 and 15 years): 75, 64, 46% vs 90, 75, 59% (P = 0.09); 30-day mortality: 14 vs 16% (P = 0.27); urgent LTx: 32 vs 17% (P = 0.04); use of cardiopulmonary bypass (CPB): 56 vs 28% (P = 0.002); intensive care unit stay: 20 ± 19 vs 10 ± 9 days (P = 0.006); AR episodes (n): 1.4 ± 0.7 vs 1.2 ± 0.8 (P = 0.004). Incidence of PGD and freedom from CLAD did not differ between groups. Predictors of mortality were: use of CPB (HR 3.12; 95% CI 1.33-7.35; P < 0.01), post-transplant diabetes mellitus (HR 2.49; 95% CI 1.13-5.43; P = 0.02) and pneumonia episodes within the first month post-transplant (HR 2.82; 95% CI 1.27-6.29; P = 0.01).ConclusionPaediatric CF patients usually present with poorer pre-transplant status, require CPB more frequently and have a higher incidence of post-LTx diabetes and infections. This might explain the trend towards a better long-term survival observed in adult CF patients.© The Author 2015.
