Total gut permeability (primarily colon permeability) was significantly increased in patients with alcohol use disorders. (a) The 24-hour urinary lactulose (% excretion of oral dose) per group. There was no statistical difference between groups (P value = 0.26). (b) The 24-hour urinary sucralose (% excretion of oral dose) per group. There was statistical difference between groups (F = 5.3, P value < 0.01). (c) The ratio of 24-hour urinary sucralose/24-hour urinary lactulose (% excretion of oral dose) per group. There was statistical difference between groups (F = 10.2, P value < 0.01).
