Mira Klein: Lung Transplantation after ex vivo lung perfusion

  1. 1. Lung transplantation after ex vivo lung perfusion: Is the quality of reconditioned donor organs as good as the standard ones? 16TH EUROPEAN CONFERENCE ON PERFUSION EDUCATION AND TRAINING IN BARCELONA 1 OCTOBER 2016 MIRA KLEIN, HIRSLANDEN ZURICH, KALAIDOS UNIVERSITY MARIANNE SCHÄRLI, KALAIDOS UNIVERSITY Mira Klein 16th ECoPEaT, Barcelona, 1 October 2016 1
  2. 2. DISCLOSURE OF CONFLICT OF INTEREST THERE IS NO CONFLICT OF INTEREST! Mira Klein 16th ECoPEaT, Barcelona, 1 October 2016 2
  3. 3. Mira Klein 3 INTRODUCTION •  Lung transplantation (LTX) the only chance for long-term survival for patients with end-stage lung diseases •  Only 15 – 30 % of available donor lungs are suitable for transplantation (van Raemdonck et al., 2009) •  To expand the usage of suitable organs, ex vivo lung perfusion (EVLP) has been established for marginal donor lungs •  Three different protocols used worldwide: «Toronto», «Lund», «Organ- Care-System» •  Equipment, perfusate composition, perfusion and ventilation strategy 16th ECoPEaT, Barcelona, 1 October 2016
  4. 4. Mira Klein 16th ECoPEaT, Barcelona, 1 October 2016 4 RESEARCH QUESTION «Has a pre-treatment of donor lungs with ex vivo lung perfusion an impact on the early clinical outcome after lung transplantation compared to lungs conventionally transplanted?»
  5. 5. Mira Klein 5 LUNG TRANSPLANTATION – STANDARD CRITERIA (ISHLT INTERNATIONAL SOCIETY OF HEART AND LUNG TRANSPLANTATION) •  Donor age < 55 years •  < 20 pack-years smoking history •  Matching size donor/recipient •  PF ratio (paO2 / FiO2) > 300 mmHg (40 kPa) •  Absence of infection •  Absence of purulent bronchial secretion •  Compatibility of blood groups •  No history of chest trauma •  No history of cardio-pulmonary surgery 16th ECoPEaT, Barcelona, 1 October 2016
  6. 6. Mira Klein 6 LUNG TRANSPLANTATION – STANDARD PROCEDURE – COLD STORAGE •  After explantation: Cold flush ante- and retrograde 60 ml/kg donor weight •  Extracellular solution (contains dextran 40, sodium, potassium, glucose – Perfadex®; Vitrolife, Gothenburg, Sweden) •  Cold storage for transport, 4 – 8 °C •  Inflation to 50% of total capacity with FiO2 50% •  Ischemic time < 6 h (< 8 h) •  Relative risk for 1-year-mortality increasing after 4.5 h (Christie, Edwards & Kucheryavaya; 2010) 16th ECoPEaT, Barcelona, 1 October 2016
  7. 7. Mira Klein 16th ECoPEaT, Barcelona, 1 October 2016 7 EX VIVO LUNG PERFUSION - GOALS •  Increase number of usable donor lungs by reconditioning and reassessing marginal organs primarily rejected for transplantation •  Safe usage of doubtful donor lungs •  Decrease mortality on the waiting lists
  8. 8. Mira Klein 8 EX VIVO LUNG PERFUSION - STRATEGY •  Simulation of physiologic in vivo situation •  Ventilation and perfusion of the normothermic lung •  Recruitment of atelectasis •  Reconditioning under physiologic circumstances •  Reassessment of organ function •  Bronchoscopic clearence •  Removal of pulmonary thrombus •  Improvement of microvascular circulation •  Recovering by preservation of normal metabolism 16th ECoPEaT, Barcelona, 1 October 2016
  9. 9. Mira Klein 9 EX VIVO LUNG PERFUSION - CONCEPT •  Reconditioning: Perfusion with oxygenated Steen Solution® (XVIVO Perfusion, Sweden) and ventilation •  After reaching normothermia reassessment of organ function •  During reassessment perfusion with a deoxygenated solution (oxygenator is «ventilated» with gas-mixture of 93% CO2 and 7% N2) to imitate venous blood composition in the pulmonary artery •  FiO2 100% and pO2 > 40 kPa (300 mmHg) or FiO2 21% and pO2 > 13 kPa (98 mmHg) and pCO2 < 6 kPa (45 mmHg) lungs will be accepted to be transplantable •  Conservation of lungs until transplantation 16th ECoPEaT, Barcelona, 1 October 2016
  10. 10. Mira Klein 10 MATERIALS AND METHODS •  Systematic literature review; selection of 11 clinical trails (2009 – 2015) •  Identification of two compareable groups: Standard procedure (StLTX) and LTX after EVLP (EVLP-LTX) •  Analysis of early clinical outcomes after Lung Transplantation •  Parameters: Postoperative ventilation hours (MV), postoperative length of ICU (LOS-ICU) and hospital stay (LOS-HOS), postoperative 30-day/1-year survival •  Interviews with four experts to validate findings from literature research 16th ECoPEaT, Barcelona, 1 October 2016
  11. 11. Mira Klein 1116th ECoPEaT, Barcelona, 1 October 2016
  12. 12. No significant differences could be found between the two groups (EVLP-LTX and StLTX) Mira Klein 12 RESULTS AND FINDINGS 16th ECoPEaT, Barcelona, 1 October 2016
  13. 13. Mira Klein 13 DISCUSSION •  EVLP offers a reliable tool to expand donor pool for lung transplantation •  Safety and reliability of the procedure were shown in different studies •  But… The procedure is expensive, demands time and requires a number of specialized staff •  Usability depends on the location of transplantation center, social and health systems of the country •  No significant differences between the three used EVLP-protocols could be found •  All procedures are comparable to the standard protocol •  Experts confirm the findings of literature •  Individual motivation for choosing a protocol 16th ECoPEaT, Barcelona, 1 October 2016
  14. 14. Mira Klein 16th ECoPEaT, Barcelona, 1 October 2016 14 CONCLUSION •  Treatment of donor lungs with EVLP has no negative impact on the early postoperative outcome after lung transplantation. •  The number of available and useable donor lungs increased after implementation of EVLP.
