Outcomes of lung transplantation for chronic obstructive pulmonary disease
Introduction
Chronic obstructive pulmonary disease is a progressive airway
disease that can progress to the terminal stage requiring oxygen supply. In this
period, lung volume reduction therapies and/or lung transplantation may be
considered. Morbidity and mortality risks due to transplant surgery and
posttransplant immunosuppressive therapy show the importance of selecting the
best candidates who will benefit from transplantation. In this context, BODE
index criteria serve as important markers. This study aimed to analyze the
outcomes of lung transplantation in patients with chronic obstructive
pulmonary disease and to identify variables that may affect post-transplant clinical
outcomes.
Materials and Methods
Lung transplants diagnosed with chronic obstructive
pulmonary disease performed in our center between March 2013 and January
2023 were included in the study. Demographic information and both pre-op
and post-op clinical data of the transplant patients were collected. The effect
of BODE index criteria and other pre-transplant clinical data on short- and
long-term outcomes after transplantation were investigated.
Results
During the study period, 34 lung transplants were performed for
chronic obstructive pulmonary disease. One patient died during the operation,
three patients received single transplants, and 30 received double transplants.
Post-operative primary graft dysfunction was more common in single transplant
recipients. The results were comparable between single and double transplants
in terms of post-transplant pulmonary function and the development of chronic
lung allograft dysfunction. BODE index criteria had no effect on early and late
post-operative clinical data, however intra-operative use of extracorporeal
membrane oxygenation, primary graft dysfunction, and prolonged extubation were
significantly higher in recipients younger than 60 years.
Conclusion
Our study suggests that prelisting demographic and clinical data
of chronic obstructive pulmonary disease patients had no significant effect on
post-operative outcomes, however, intra-operative ECMO use, prolonged
extubation, primary graft dysfunction (p< 0.05 for each) and chronic rejection
(p> 0.05) were more common in patients who are <60 years of age. These
data need to be confirmed by larger studies.
