    Abstract:
    BACKGROUND AND AIMS: Alcohol-related liver disease is a leading cause of liver-related mortality. The effect of alcohol abstinence on the natural history of alcohol-related cirrhosis across distinct stages of portal hypertension has not been thoroughly investigated. In this study, we assessed the clinical implications of abstinence in patients with alcohol-related cirrhosis and clinically significant portal hypertension. METHODS: Alcohol abstinence, hepatic decompensation, and mortality were assessed in patients with alcohol-related cirrhosis who underwent a baseline hepatic venous pressure gradient (HVPG) measurement and were diagnosed with clinically significant portal hypertension (HVPG ≥10 mm Hg). RESULTS: A total of 320 patients with alcohol-related cirrhosis (median age: 57 [interquartile range (IQR), 49.7-63.1] years; 75.6% male; 87.5% decompensated) and a median HVPG of 20 (IQR, 17-23) mm Hg were followed up for a median of 36 (IQR, 14-80) months. Overall, 241 (75.3%) patients remained abstinent, while 79 (24.7%) patients had active alcohol consumption. Alcohol abstinence was linked to a significantly reduced risk of hepatic decompensation (adjusted hazard ratio [aHR], 0.391; P < .001), as well as liver-related (aHR, 0.428; P < .001) and all-cause (aHR, 0.453; P < .001) mortality, after adjusting for baseline HVPG, MELD, and previous decompensation. Importantly, alcohol abstinence significantly reduced the cumulative incidence of hepatic decompensation in both groups with HVPG 10-19 mm Hg (P < .001) and HVPG ≥20 mm Hg (P = .002). The 3-year decompensation probability was 32.4% vs 60.0% in HVPG 10-19 mm Hg and 57.5% vs 82.6% in HVPG ≥20 mm Hg for abstinent patients vs active drinkers, respectively. CONCLUSIONS: Alcohol abstinence improves prognosis across all stages of portal hypertension in alcohol-related cirrhosis, including in patients who have already progressed to high-risk portal hypertension.
