Living Donor Liver Transplantation During the COVID-19 Pandemic: an Evolving Challenge.

backgroundMaintaining standards of living donor liver transplantation (LDLT) can be a challenge during the corona virus disease 2019 (COVID-19) pandemic. Center-specific protocols have been developed and transplant societies propose limiting elective LDLT. We have looked at outcomes of LDLT during the pandemic in an exclusively LDLT center.

methodsPatients were grouped into pre-COVID (January 2019-February 2020) (n = 162) and COVID (March 2020-January 2021) (n = 53) cohorts. We looked at patient characteristics, 30-day morbidity, and mortality. Outcomes were also assessed in donors and recipients who underwent surgery after recovery from COVID-19.

resultsThe average number of transplants reduced from 11.5/month to 4.8/month. Fewer patients with MELD > 20 underwent LDLT in the COVID cohort (41.3% versus 24.5%, P = 0.03). Out of nine patients with a positive pretransplant COVID-19 PCR, there were 2 (22.3%) deaths on the waiting list. Seven patients underwent LT after recovery from COVID-19 with one 30-day mortality due to biliary sepsis. Three donors with positive COVID-19 PCR underwent uneventful donation after testing negative for COVID-19. No significant difference in 30-day survival was observed in the pre-COVID and COVID cohorts (93.2% versus 90.6%) (P = 0.3). Out of two recipients who developed COVID-19 pneumonia within 30 days after LT, there was one mortality. The 1-year survival for the entire cohort with a MELD cutoff of 20 was 90% and 84% (P = 0.2).

conclusionDespite comparable outcomes, fewer sick patients might undergo LDLT during the pandemic. Individuals recovered from COVID-19 might be safely considered for donation or transplantation.
