Objective In this study we retrospectively evaluated impact of donor history and extent of smoking on mid-term outcome after LTx.
Methods Between 01.2007 and 09.2012, 237 LTx were performed in our institution (5 patients were excluded due to unknown donor smoking history). Patients were divided in 3 groups receiving lungs from: 123 (53%) non-smoking donors (NS), 68 (29%) smoking donors – <20 pack years (S) and 41 (18%) heavy smokers – >20 pack years (HS). Donor and recipient demographics as well as perioperative data and mid-term outcome were compared.
Results There were no statistically significant differences in: donor cause of death; percentage of: DCD, abnormal CXR and bronchoscopy, Ex Vivo Lung Perfusion (EVLP); donor duration of mechanical ventilation (MV); last pre-retrieval PaO2/FiO2 ratio and total ischemic time. Donors from HS group were significantly older (p<0.001). Preoperative recipient demographics and diagnosis distribution were also comparable. Parameters of early postoperative outcome are presented in Table 1.
|Outcomes after transplantation||NS||S||HS||p value|
|PaO2/FiO2 ratio 24 hours (mmHg)||348.9±109.6||328.3±108.5||344.9±105.5||0.466|
|PaO2/FiO2 ratio 48 hours (mmHg)||351.4±112.4||352.8±123.6||346.1±95.4||0.956|
|PaO2/FiO2 ratio 72 hours (mmHg)||348.0±120.4||341.4±114.4||364.0±109.1||0.652|
|Duration of mechanical ventilation (hours)||35(14;198)||50(23;474)||34(10;96)||0.136|
|Intensive care unit stay (days)||5(3;19)||11(3;26)||6(3;19)||0.133|
|Hospital stay (days)||34(21;51)||33(23;59)||39(27;56)||0.322|
There were no statistically significant differences in prevalence of bronchiolitis obliterans syndrome (p=0.616) as well as BOS free survival (p=0.898). 1 and 3 years survival estimate was also comparable: NS vs. S vs. HS – 77.7% vs. 90.8% vs. 94.9% and 68.7% vs. 82.1% vs. 68.2% (log rang p=0.151).
Conclusions History and extent of donor smoking do not adversely affect LTx mid-term outcome. However, long term observation is necessary.
