Abstract
OBJECTIVES: Extended donors (EDs) are safely used to increase the donor pool in lung transplantation (LT), but their influence in critically ill patients (extended recipients [ERs]) remains controversial. We compared LT outcomes matching optimal donors (ODs) or EDs with optimal recipients (ORs) or ERs. METHODS: Three hundred and sixty-five LTs were reviewed. ED criteria: age >55, PaO2/FiO2 < 350 mmHg, pulmonary infiltrates/purulent secretions and ischaemic times >6 h (single LT [SLT]) and >9 h (double LT [DLT]). ER criteria: pulmonary fibrosis or pulmonary hypertension, pretransplant intubation, age >60 years and bypass >2 h. Four groups were created: Group 1 (OD/OR), Group 2 (OD/ER), Group 3 (ED/OR) and Group 4 (ED/ER). Thirty-day mortality, primary graft dysfunction (PGD), onset of bronchiolitis obliterans syndrome (BOS), long-term survival and other transplant outcomes were compared between OD and ED, OR and ER and among the four groups of study. RESULTS: There were 151 SLTs and 214 DLTs. Donors: OD (n = 229) vs ED (n = 136); PGD 8 vs 10% (P = 0.43); 30-day mortality 19 vs 20% (P = 0.53) and survival (1, 5, 10 and 15 years) 67, 47, 34, 26 vs 69, 53, 46 and 29% (P = 0.33). Recipients: OR (n = 182) vs ER (n = 183); PGD 7 vs 10% (P = 0.10); 30-day mortality 15 vs 23% (P = 0.04) and survival (1, 5, 10 and 15 years): 73, 57, 46, 30 vs 61, 42, 29 and 23% (P = 0.002). Four donor/recipient (D/R) groups: Group 1 (n = 122), Group 2 (n = 106), Group 3 (n = 61), Group 4 (n = 76); PGD 10, 6, 3 and 16% (P = 0.05); 30-day mortality 13, 26, 19 and 20%, respectively (P = 0.13); survival (1, 5, 10 and 15 years) 74, 55, 44 and 35% (Group 1), 55, 39, 22 and 16% (Group 2), 70, 59, 48 and 26% (Group 3) and 68, 47, 37 and 22% (Group 4) (P = 0.004). No differences in the onset of BOS were observed among the four study groups. CONCLUSIONS: LT in critically ill recipients is associated with poor early and long-term outcomes, irrespective of the quality of the donor and length of ischaemic times.
