Inclusion of sarcopenia improves the prognostic value of MELD score in patients after transjugular intrahepatic portosystemic shunt.

Abstract

ObjectiveTo explore the predictive value of model for end-stage liver disease (MELD)-Sarcopenia score for survival of cirrhotic patients after transjugular intrahepatic portosystemic shunt (TIPS) placement.Methods289 patients who underwent TIPS between February 2016 and December 2020 were included, they were divided into the sarcopenia group (n = 138) and non-sarcopenia group (n = 151) according to whether they were complicated with sarcopenia. Kaplan–Meier curve was used to analyze and compare the prognosis of the above two groups and multivariate Cox regression analysis was used to identify the independent prognostic factors. The performance of different predictive models was compared using C-index.ResultsDuring the follow-up, Kaplan–Meier analyses indicated that cumulative survival was significantly lower in sarcopenia group than that in non-sarcopenia group [74.6% vs. 92.7%, HR, 0.24 (95% confidence interval (CI), 0.12–0.46), Log-rank P < 0.001]. After multivariate Cox analysis, age [HR, 1.040 (95% CI, 1.015–1.065), P = 0.002], sarcopenia [HR, 3.948 (95% CI, 1.989–7.838), P < 0.001], albumin [HR, 0.945 (95% CI, 0.897–0.997), P = 0.037], and MELD score [HR, 1.156 (95% CI, 1.097–1.217), P < 0.001] were identified as the independent risk factors for mortality after TIPS. The C-indexes of MELD-Sarcopenia, Child-Pugh, MELD, MELD-Na, and the Freiburg index of post-TIPS survival (FIPS) scores were 0.782, 0.688, 0.719, 0.734, and 0.770, respectively.ConclusionSarcopenia is independently correlated with post-TIPS mortality, and MELD-Sarcopenia score showed the best performance in predicting post-TIPS mortality than the traditional predictive models.
