| Abstract | Background: Predicting complications after liver transplantation (LT) remains challenging. We propose incorporating the De Ritis ratio (DRR), a widely known parameter of liver dysfunction, into current or future scoring models to predict early allograft dysfunction (EAD) and mortality after LT. Methods: A retrospective chart review was conducted on 132 adults receiving a deceased donor LT from April 2015 to March 2020 and their matching donors. Donor variables, postoperative liver function, and DRR were correlated with the occurrence of EAD, post-transplant complications expressed by the Clavien-Dindo score, and 30-day mortality as outcome variables. Results: Early allograft dysfunction was observed in 26.5% of patients and 7.6% of patients who died within 30 days after transplant. Recipients were more likely to experience EAD when receiving grafts from donation after circulatory death (P = .04), donor risk index (DRI) >2 (P = .006), ischemic injury at time-zero biopsy (P = .02), longer secondary warm ischemia time (P < .05), or higher Clavien-Dindo scores (IIIb-V; P < .001). The DRI, total bilirubin, and DRR on postoperative day 5 yielded significant associations with the primary outcomes and were used to develop the Gala-Lopez score using a weighted scoring model. This accurately predicted EAD, high Clavien-Dindo, and 30-day mortality in 75%, 81%, and 64% of patients. Conclusion: Including recipient and donor variables in predictive models, and for the first time DRR, as a constituent, should be regarded to predict EAD, severe complications, and 30-day mortality post-LT. Further studies will be required to validate the present findings and their applicability when using normothermic regional and machine perfusion technologies. |
