Abstract: BACKGROUND: Endotoxaemia is commonly seen in cirrhotic patients with ascites and this may be associated with increased portal pressure. AIM: To investigate the effect of intestinal decontamination on liver haemodynamics in alcohol-related cirrhotic patients with ascites. METHODS: We included 30 patients. At day 0, systemic and splanchnic circulation endotoxin levels were determined and HVPG measurement performed. Patients received rifaximin (1200 mg/day) for 28 days. At day 29, systemic and splanchnic circulation endotoxin levels were determined and HVPG measurement performed again. RESULTS: Median (range) plasma endotoxin levels decreased significantly after rifaximin administration both in systemic [1.45(0-3.1) vs. 0.7(0-2.7), P < 0.0001] and splanchnic circulation [1.8(0-3.4) vs. 0.8(0-2.1), P < 0.0001]. Meanwhile, the difference seen in endotoxin levels between the splanchnic and systemic circulation at day 0 (P = 0.001) was not noted at day 29 (P = 0.137). HVPG measurement was possible in 28 patients. Median (range) HVPG values were 18 mmHg (12.7-26.3) on day 0 vs. 14.7 mmHg (7-20) on day 29 (P < 0.0001). HVPG decreased after rifaximin in 23, remained stable in two and increased in three patients. CONCLUSION: Hepatic venous pressure gradient values decreased significantly after intestinal decontamination with rifaximin in patients with alcohol-related decompensated cirrhosis and this might have been achieved through significant reduction of plasma endotoxin levels.
