Insights

Lung transplantation using controlled donation after circulatory death (cDCD) donors shows comparable short-term survival and primary graft dysfunction to donation after brain death (DBD) donors. Long-term outcomes and airway complications warrant further investigation.

Area of Science:

  • Cardiovascular Sciences
  • Transplantation Medicine
  • Pulmonary Medicine

Background:

  • Rising demand for lung allografts has renewed interest in donation after circulatory death (DCD) donors for lung transplantation (LT).
  • Clinical outcomes following DCD lung transplantation have demonstrated satisfactory results.
  • This systematic review analyzes outcomes of LT using controlled DCD (cDCD) versus donation after brain death (DBD) donors.

Purpose of the Study:

  • To systematically review and analyze published data on lung transplantation outcomes comparing cDCD and DBD donors.
  • To evaluate the efficacy and safety of lung allografts from cDCD donors.

Main Methods:

  • A comprehensive literature search was conducted in Cochrane Database of Systematic Reviews, PubMed, and Web of Science.
  • Relevant articles were independently assessed by two authors, with quality evaluation using NIH protocols.
  • Pooled Odds Ratios and mean differences were calculated using random-effect models to analyze outcomes.

Main Results:

  • Nine studies involving 2973 patients (403 cDCD, 2570 DBD) were included.
  • No significant differences were observed in 1-year survival (OR=1.00) or primary graft dysfunction (PGD) (OR=1.03) between cDCD and DBD groups.
  • Higher rates of airway complications (OR=2.07) and lower rates of chronic lung allograft dysfunction (CLAD) (OR=0.57) and 5-year survival (OR=0.57) were noted with cDCD, requiring further research.

Conclusions:

  • Lung transplantation from cDCD donors yields comparable 1-year survival, PGD, and 1-year freedom from CLAD to DBD donors.
  • While airway complications and long-term survival showed associations with cDCD, these findings require additional investigation.
  • cDCD donors represent a viable option for lung transplantation, though specific complications need monitoring.
