A Mushroom Meal Two Days Ago - Hepatology clinical simulation case. A 54-year-old man brought by EMS 48 hours after ingesting a wild mushroom stew....
Age: 54 • Gender: Male • Setting: Emergency Triage
Clinical Presentation & History
A 54-year-old man brought by EMS 48 hours after ingesting a wild mushroom stew. Initial violent vomiting and profuse watery diarrhea appeared to resolve overnight, but today he has worsening fatigue, persistent right upper quadrant discomfort, dark urine, and clay-colored stools. Family states the rest of the family only had small portions and are asymptomatic. Foraged wild mushrooms (mushrooms the family identified online as 'chicken of the woods') in a wooded area two days ago. Cooked in a stew with the family of four. Patient consumed the largest portion. Past medical history: hypertension on lisinopril. No liver disease. Drinks 4-6 beers on weekends.
Acute Resuscitation Milestones & Priorities
Clinical phases and key interventions encountered in this emergency module:
Amanita phalloides poisoning classically presents with a biphasic course: violent GI symptoms 6-24h after ingestion, an apparent recovery 24-48h, then fulminant hepatic failure 48-96h. The 'silent interval' is the diagnostic trap.
Silibinin (Legalon SIL) blocks hepatocyte alpha-amanitin uptake via OATP1B3 inhibition and is the only agent shown to reduce mortality in the hepatotoxic phase. Combined with IV N-acetylcysteine and multi-dose activated charcoal, it forms the modern antidote triad.
King's College Criteria for Amanita-induced fulminant hepatic failure: INR >6.5 OR (INR >3.5 with grade ≥3 encephalopathy). Listing under Status 1A is the definitive intervention; early activation of the transplant center before meeting criteria improves survival.
