Severe Alcoholic Hepatitis
Fresh hep.* prefix dossier; manifest is batch23 scaffold (no AH-specific workup adapter; uses sbp_workup + hepatic_encephalopathy + hepatorenal_syndrome). Severity gates: Maddrey DF >=32 (PMID 352788) OR MELD >=21 (Crabb 2020 PMID 31314133); both embedded in regimen rationale since no calc.maddrey/calc.lille registry entries exist. STOPAH 2015 (PMID 25901427) - prednisolone trend; pentoxifylline NEGATIVE - explicitly NOT recommended. Lille day-7 score (PMID 17518367) drives steroid continuation vs early transplant decision; non-responders go to Mathurin 2011 (PMID 22070476) early TX pathway. PREDNISOLONE not prednisone (no hepatic conversion needed in failing liver). NAC adjunct per Nguyen-Khac 2011 (rationale only; not separately PMID-anchored here). Sibling differentiation vs cirrhosis + ALF explicit.
