TRANSPLANTATION TIMELINE 1963 - Dr. James Hardy single lung tx in male patient, 58 y.o., life sentence in prison, with bronchogenic CA and severe BPCO � immunosuppression: AZA, prednisone, cobalt irradiation � survived 18 days (renal failure; an autopsy showed no evidence of rejection) www.eurotransplant.org early 2000's: double lung transplant more common

… IL POLMONE E’ DIVERSO ! maggiore rischio di danno da riperfusione (ampia area endoteliale) ! contatto con l’ambiente esterno ! ridotti meccanismi di difesa: organo denervato � no riflesso tussigeno http://www.ctstransplant.org

CONTROINDICAZIONI INDICAZIONI

INDICAZIONI a chronic, end-stage lung disease who meet all the following general criteria: 1. High (>50%) risk of death from lung disease within 2 years if lung transplantation is not performed. 2. High (>80%) likelihood of surviving at least 90 days after lung transplantation. 3. High (>80%) likelihood of 5-year post-transplant survival from a general medical perspective provided that there is adequate graft function J Heart Lung Transplant 2015 Jan;34(1):1-15.

CONTROINDICAZIONI ABSOLUTE CONTRAINDICATIONS • malignancy within prior 2 years • another major organ failure (heart, liver, kidney) • chronic infection with highly virulent and/or resistant microbes that are poorly controlled pre-transplant • substance abuse or dependence (alcohol, tobacco, marijuana, ...) • no compliance / psychiatric conditions associated with the inability to cooperate • acute medical instability (acute sepsis, myocardial infarction, liver failure, ...) • uncorrectable bleeding diathesis • BMI ≥ 35 • absence of an adequate social support system

RELATIVE CONTRAINDICATIONS • age >65 years • mechanical support (mechanical ventilation and/or ECLS), but... • chronic colonization or infection with highly resistant or highly virulent bacteria, fungi, and certain strains of mycobacteria � hepatitis B and/or C, HIV+ � Burkholderia cenocepacia, Burkholderia gladioli � multi-drug-resistant Mycobacterium abscessus • other medical conditions with not end-stage organ damage (diabetes mellitus, systemic hypertension, epilepsy, UP, GERD) � should be optimally treated before transplantation • BMI 30-34 or <17 • severe, symptomatic osteoporosis • extensive prior chest surgery with lung resection

MANAGEMENT OF THE WAITING LIST “…It is imperative that all wait-listed patients be regularly evaluated...ensuring that candidate selection is not simply a one-time static determination but rather a continuous process. “ REMOVAL FROM THE WAITING LIST either temporarily or permanently NEGATIVE DEVELOPMENT Development of any of the above-discussed absolute or relative contraindications: changes in weight or rehabilitation status, renal failure, demonstrable medical non-compliance, or patient ambivalence toward transplantation Patients bridged by mechanical ventilation and/or ECLS, who more frequently develop changes in clinical status that would preclude the likelihood of an acceptable transplant outcome. POSITIVE DEVELOPMENTS Response to medical therapy ( > APH) Improvement in quality of life status that would alter the risk/benefit equation away from transplantation at the current time should prompt a reevaluation of a patient’s transplant candidacy Weill et al, J. Heart Lung Transplant. 2015; 34: 1–15.

SPECIAL TRANSPLANT CIRCUMSTANCES Lung retransplantation • Of the 55.795 reported adult lung transplants that were performed through June 2015: 2.187 (3.9%) had a first retransplantation and 86 (0.2%) had a second retransplantation. • BILATERAL >> SINGLE TX Ipsilateral single-lung retransplantation has been associated with a higher acute risk of death compared with contralateral single-lung retransplantation • patients who are >2 years out from initial transplantation fare better than patients retransplanted earlier.

KEY POINTS • il trapianto polmonare è diventato un mezzo efficace e affidabile per migliorare la sopravvivenza e la qualità della vita in pazienti accuratamente selezionati con malattia polmonare end-stage • Il successo attuale nel trapianto è attribuito ad un timing corretto di rinvio ed inserimento in lista d’attesa, alla presenza di un team multidisciplinare, al miglioramento della gestione dei donatori e all’attento follow-up dei trapiantati
