Abstract:

BACKGROUNDS: Antiviral therapy (AVT) may improve liver histology in patients with advanced viral hepatitis but its effect on portal pressure remains unknown.

AIM: This study was aimed to evaluate the influence of antiviral therapy (AVT) on hepatic venous pressure gradient (HVPG) in hepatitis C virus infected patients with portal hypertension.

METHODS: Twenty compensated patients with chronic hepatitis C, fibrosis stage 3 or 4 and HVPG > 5 mmHg received PEG-IFN α2b plus ribavirin. Every patient underwent liver biopsy and portal pressure measurements before and immediately after AT. Biopsies were evaluated according to METAVIR score.

RESULTS: HVPG significantly dropped in all but one treated patient, with a mean (SD) reduction of 28.2 (12)%[13.8 (5.6) Vs. 10.2 (3.8) mmHg, p = 0.005]. The percentage of HVPG decrease was significantly greater in patients who achieved a virological end of treatment response [26.2 (12.5)% Vs. 12.7 (8.5)%, p = 0.05] and in those with a decrease of at least 2 points in the grade of inflammation [35.7 (4.5)% Vs. 22.1 (9.5)%, p = 0.015]. Nine out of 11 patients with baseline HVPG ≥ 12 mmHg showed a decrease greater than 20% (3/11) or under the 12 mmHg threshold (6/11).

CONCLUSIONS: AVT reduces HVPG in compensated patients with advanced hepatitis C (fibrosis stage 3 or 4) and portal hypertension.
