Recompensation of decompensated cirrhosis in a spectrum of metabolic-dysfunction-related steatotic liver disease, with PEth-corroborated alcohol abstinence and modification of cardiometabolic risk factors.

Treatment of AUD with sustained abstinence is the most effective strategy to prevent progression and improve long-term outcomes at any stage of ALD; ACG recommends brief screening with a tool such as AUDIT-C (strong, high), brief motivational interventions (strong, low), and integrated multidisciplinary care combining behavioral therapy and/or pharmacotherapy (strong, low). AUD pharmacotherapy recommendations are scoped specifically to COMPENSATED ALD and are not co-equal: baclofen is recommended as an option (strong recommendation, moderate evidence); acamprosate or naltrexone are only suggested as options (conditional, very low); gabapentin or topiramate are suggested as options (conditional, very low); disulfiram is suggested AGAINST along any spectrum of ALD (conditional, very low). For severe alcohol withdrawal, benzodiazepines are the treatment of choice but with explicitly cautious use and careful monitoring given their potential to precipitate or exacerbate hepatic encephalopathy (strong, moderate); AWS is managed per CIWA-Ar protocol, differentiating it from HE while acknowledging the two can coexist. For alcohol-associated hepatitis (AH), severity is stratified by MELD: MELD >20 defines severe AH, which carries high short-term mortality and should preferably be managed in hospital; MELD ≤20 defines moderate AH. In severe AH (MELD >20) ACG recommends corticosteroid therapy ONLY if there are no contraindications (strong, moderate); active infection (including untreated HBV infection), uncontrolled diabetes mellitus, gastrointestinal bleeding, and severe renal failure are contraindications to corticosteroid use, though corticosteroids can be started after adequate control or reversal of infection, renal failure, and gastrointestinal bleeding. Prednisolone is preferred over prednisone; both are dosed 40 mg/day for a total of 4 weeks, with IV methylprednisolone 32 mg/day as the alternative for patients unable to take oral medication; there is no evidence supporting rapid vs slow tapering after the 4-week course. Corticosteroid response is assessed by Lille score at day 7 OR day 4 (day-4 shown as accurate as day-7); among non-responders (Lille >0.45) corticosteroids should be discontinued. ACG recommends IV N-acetylcysteine as an adjuvant to corticosteroids in severe AH (strong, moderate), while explicitly noting that other society guidelines have not adopted this recommendation. ACG recommends AGAINST pentoxifylline (strong, moderate) and AGAINST universal prophylactic antibiotics in hospitalized severe AH (strong, moderate); data on G-CSF and microbiome-based therapies are insufficient. Nutrition: target 35 kcal/kg/day with 1.2-1.5 g/kg/day protein; patients consuming <21 kcal/kg/day should receive nutritional support, preferably oral/enteral, oral nutritional supplements first, escalating to enteral nutrition if caloric targets remain unmet (strong, moderate). Thiamine, vitamin B12 and zinc deficiencies are common in AH and should be supplemented. For severe AH unresponsive to medical management with high risk of death, early liver transplantation for highly selected patients should be considered according to regional and institutional protocols (conditional recommendation, low level of evidence); LT selection must not be based solely on an arbitrary duration of sobriety, and should rest on detailed psychosocial evaluation by a social worker and addiction specialist, optionally supported by tools such as SIPAT, HRAR, MAPS, HPSS or SALT. For severe AH with 4 or more organ failures, non-responsive to corticosteroids and ineligible for early LT, palliative care engagement is appropriate.
