BACKGROUND & AIMS: Wedge hepatic vein pressure (WHVP) accurately estimates portal pressure (PP) in alcohol- or viral hepatitis-related cirrhosis. Whether this also holds true in cirrhosis caused by non-alcoholic steatohepatitis (NASH) is unknown. We aimed to evaluate the agreement between WHVP and PP in patients with NASH cirrhosis in comparison to patients with alcohol- or HCV-related cirrhosis.
METHODS: All consecutive patients with NASH cirrhosis treated with a transjugular intrahepatic portosystemic shunt (TIPS) in 3 European centres were included (NASH group; n = 40) and matched with 2 controls (1 with alcohol-related and 1 with HCV-related cirrhosis) treated with TIPS contemporaneously (control group; n = 80). Agreement was assessed by Pearson's correlation (R), intra-class correlation coefficient (ICC), and Bland-Altman method. Disagreement between WHVP and PP occurred when both pressures differed by >10% of PP value. A binary logistic regression analysis was performed to identify factors associated with this disagreement.
RESULTS: Correlation between WHVP and PP was excellent in the control group (R 0.92; p <0.001; ICC 0.96; p <0.001) and moderate in the NASH group (R 0.61; p <0.001; ICC 0.74; p <0.001). Disagreement between WHVP and PP was more frequent in the NASH group (37.5% vs. 14%; p = 0.003) and was mainly because of PP underestimation. In uni- and multivariate analyses, only NASH aetiology was associated with disagreement between WHVP and PP (odds ratio 4.03; 95% CI 1.60-10.15; p = 0.003).
CONCLUSIONS: In patients with decompensated NASH cirrhosis, WHVP does not estimate PP as accurately as in patients with alcohol- or HCV-related cirrhosis, mainly because of PP underestimation. Further studies aimed to assess this agreement in patients with compensated NASH cirrhosis are needed.
LAY SUMMARY: Portal pressure is usually assessed by measuring wedge hepatic vein pressure because of solid evidence demonstrating their excellent agreement in alcohol- and viral hepatitis-related cirrhosis. Our results show that in patients with decompensated cirrhosis caused by non-alcoholic steatohepatitis, wedge hepatic vein pressure estimates portal pressure with less accuracy than in patients with other aetiologies of cirrhosis, mainly because of portal pressure underestimation.
