Transjugular Intrahepatic Portosystemic Shunt does not affect the efficacy and safety of direct-acting antivirals in patients with advanced cirrhosis: A real-life, case-control study

Abstract

Background: Transjugular Intrahepatic Portosystemic Shunt (TIPS) is a well-established treatment for complications of portal hypertension.

Aims: To analyze the impact of TIPS on virologic response and safety profile in patients treated with direct-acting antivirals (DAAs).

Methods: We analyzed data from HCV-positive cirrhotic patients treated with DAAs. Twenty-one patients with previous TIPS placement were compared with 42 matched subjects without TIPS. Logistic regression was used to identify predictors of hepatic function worsening and adverse events.

Results: No differences were found between the two groups in particular regarding sustained virologic response (92.5 and 97.6% in TIPS vs no-TIPS, p = 0.559). Model for End-stage Liver Disease (MELD) of both TIPS and no-TIPS groups declined from baseline to week 24 of follow-up (from 12.5 ± 3.5 to 10.8 ± 3.4 and from 11.1 ± 3.5 to 10.3 ± 3.4, p = 0.044 and 0.025). There were no differences in adverse event rates. At univariate analysis, age was associated with MELD increase from baseline to week 24 (OR 1.111, 95% CI 1.019-1.211, p = 0.017), and patients with higher baseline MELD developed serious adverse events more frequently (OR 0.815, 95% CI 0.658-1.010, p = 0.062). Patients with or without TIPS did not show differences in transplant-free survival.

Conclusion: TIPS placement does not affect virologic response and clinical outcome of patients receiving DAAs.
