Combination of Model for End-Stage Liver Disease (MELD) and Sarcopenia predicts mortality after transjugular intrahepatic portosystemic shunt (TIPS).

UNLABELLED TIPS is the most effective treatment for portal hypertension. Patient selection remains important to achieving optimal post-TIPS outcomes. The study evaluates 1-year mortality factors in cirrhotic patients receiving TIPS. METHODS 87 cirrhotic patients received a TIPS between 2015 - 2021. Predictors of 1-year and overall mortality were assessed by estimating cumulative incidence functions and Grey's test to adjust for liver transplantation as a risk competing with mortality. Variables with p < 0.05 were checked for collinearity and included in the multivariate Cox proportional hazards model. Model discrimination was evaluated by calculating the area under the ROC curve. RESULTS 87 patients were included (68% men; 22% ≥70 years). ALD was the primary cirrhosis cause. Most patients were Child-Pugh class B, MELD-Na score was 13.6 ± 6.0 points. The most frequent indication for TIPS was bleeding (51.7%), followed by refractory ascites (42.5%). The variables positively associated with mortality in univariate analysis were ascites, clinically overt sarcopenia and MELD-Na score, while ongoing nutritional supplementation improved survival. In the multivariate analysis, only clinically overt sarcopenia and MELD-Na score remained independently associated with mortality. A MELD-Na/sarcopenia model demonstrated a good discrimination, AUROC: 0.86 (95% CI 0.77 - 0.95). CONCLUSION MELD-Na score, and sarcopenia were significantly associated with 1-year survival in cirrhotic patients who received TIPS.
