Therapeutic options to treat progression of end-stage liver disease (ESLD) or improve long-term survival after liver transplantation remain scarce. We investigated the impact of coffee consumption under these conditions.
We recorded coffee consumption habits of 379 patients with ESLD awaiting liver transplantation and 260 patients after liver transplantation. Survival was analyzed based on coffee intake.
195 patients with ESLD consumed coffee on a daily basis, while 184 patients did not. Actuarial survival was impaired (p = 0.041) in non-coffee drinkers (40.4 ± 4.3 months, 95% CI: 32.0-48.9) compared to coffee drinkers (54.9 ± 5.5 months, 95% CI: 44.0-65.7). In subgroup analysis, the survival of patients with alcoholic liver disease (ALD; p = 0.020) and primary sclerosing cholangitis (PSC; p = 0.017) was increased with coffee intake, while unaffected in patients with chronic viral hepatitis (p = 0.517) or other liver disease entities (p = 0.652). Multivariate analysis showed that coffee consumption of PSC and ALD patients retained as an independent risk factor (OR: 1.94; 95% CI: 1.15-3.28; p = 0.013) along with MELD-Score (OR: 1.13; 95% CI: 1.09-1.17; p = 0.000). Following liver transplantation, long-term survival was longer in coffee drinkers (coffee: 61.8 ± 2.0 months, 95% CI: 57.9-65.8) than non-drinkers (52.3 ± 3.5 months, 95% CI: 45.4-59.3; p = 0.001).
Coffee consumption delayed disease progression in ALD and PSC patients with ESLD and increased long-term survival after liver transplantation. We conclude that regular coffee intake might be recommended for these patients.
