Spleen Stiffness Measurements Predict the Risk of Hepatic Decompensation After Direct-Acting Antivirals in HCV Cirrhotic Patients.

Abstract

Little evidence is available regarding the risk of hepatic decompensation (HD) after direct-acting antivirals (DAAs) in patients with advanced chronic liver disease. Our aim was to assess the risk of decompensation and the prognostic role of noninvasive tests, such as liver (LSM) and spleen (SSM) stiffness measurements, in the prediction of decompensation after sustained virologic response (SVR) by DAAs. A cohort study involving 146 cirrhotic patients treated with DAAs in our tertiary center with LSM and SSM available both before and six months after treatment (SVR24). A historical cohort of 92 consecutive cirrhotic patients with active HCV was used as a control group. A propensity score inverse probability weighting method was used to account for differences between the groups. Time-dependent models for the prediction of decompensation were applied to account for changes in noninvasive tests after therapy. The decompensation incidence in the DAA cohort was 7.07 (4.56-10.96) per 100 person-years (PYs), which was significantly lower than in the active HCV cohort. The DAA therapy was an independent protective factor for HD development (SHR: 0.071, 95 %-CI: 0.015-0.332). SSM ≥ 54 kPa was independently associated with decompensation despite SVR achievement (SHR: 4.169, 95 %-CI: 1.050-16.559), alongside with a history of decompensation (SHR: 7.956, 95 %-CI: 2.556-24.762). SSM reduction < 10 % also predicted the risk of decompensation after SVR24. The risk of decompensation was markedly reduced after DAA therapy, but it was not eliminated. Paired SSM values stratified the risk of decompensation after SVR better than other noninvasive tests.
