Aim. 1: To test the efficacy of 6-month LGG compared to placebo in treating AUD: (1a) by lowering heavy drinking (1b) by reducing relapse episodes to minimal/absent incident level; (1c) by showing a significant positive effect on one or more of the underlying neurobehavioral domain, and (1d) by lowering a biochemical marker of alcohol intake.~Aim. 2: To test if 6-month LGG treatment compared to placebo will improve the symptoms and liver injury in AH: (2a) by significantly improving liver related tests (AST, ALT, AST:ALT, albumin, bilirubin and INR; K18M65 and K18M30) and clinical severity/prognostic markers (MELD, Maddrey); (2b) by substantially improving the overall health as assessed by the patient reported outcomes (Quality of Life [QOL] scale, and drinker inventory of consequences [DrInC]); and (2c) by lowering frequency and intensity of treatment/disease based adverse effects (AE).~Aim. 3: To evaluate the effects of LGG treatment compared to placebo on therapeutic-mechanistic markers of gut-brain axis and pro-inflammatory activity in patients with AUD and moderate AH: (3a) by identifying the blood biomarkers of gut-barrier dysfunction and endotoxemia, and inflammation; (3b) by determining the therapeutic targets of LGG involved in the gut-brain axis of AUD using LC-MS metabolomic fecal assays (candidate markers of gut-dysfunction associated neurotransmitters); and (3c) by validating the efficacy of LGG treatment vs. placebo to lower inflammation using an ex-vivo design.
To test the efficacy of 6-month LGG compared to placebo in treating Alcoholic Use Disorder (AUD) and liver injury in Alcoholic Hepatitis (AH). And to evaluate the effects of LGG treatment compared to placebo on therapeutic-mechanistic markers of the gut-brain axis and pro-inflammatory activity in patients with AUD and moderate AH
