The predictive value of MELDNa (model for end-stage liver disease-sodium) and mean platelet volume/platelet count for patients' 30-day mortality after liver transplantation.

Abstract

Aim of the studyTo investigate the disease-specific score and improve the existing scores to better determine the prognosis of patients after liver transplantation (LT). For this purpose, we evaluated the relationship of prognostic scores with 30-day mortality after LT. In addition, we planned to investigate whether the mean platelet volume/platelet count (MPR) would contribute to score improvement.Material and methodsA total of 178 adult patients admitted to the intensive care unit after LT in our hospital between 2011 and 2019 were retrospectively analyzed. Model for end-stage liver disease-sodium (MELDNa), Child-Turcotte-Pugh (CTP) score, and MPR values were compared in patients with and without 30-day mortality who underwent LT. Logistic regression analysis was performed to determine the predictive factors for mortality. A model was created with multivariate analysis.ResultsOur study included 135 (75.8%) male and 43 (24.2%) female patients. There was a significant difference in the postLT-MELDNa score in the evaluation between those with and without mortality (p < 0.001). Age, postLT-MELDNa and CTP score were found to be significant in terms of the prediction of 30-day mortality in the univariate analysis (p < 0.05). mean platelet volume (MPV) and MPR were not significant in univariate analysis. Multivariate analysis revealed a model in which age and postLT-MELDNa were significant.ConclusionsIn our study, postLT-MELDNa predicted 30-day mortality and was much more effective in predicting mortality when evaluated with age. The MELDNa score, which is currently used in the prognosis of candidates awaiting LT, may be useful for the prognosis of patients after LT in intensive care units.
