Acute liver failure != chronic liver failure
Definition
AASLD definition = 1. coagulopathy 2. encephalopathy 3. <=26 weeks (not 8, not 6)
- Causes: Viral hepatitis (A rare B C rare D E (in pregnancy) EBV CMV Herpes VZV hemophagocytic syndrome). Alcohol (MDF>32 -> steroids, PTX). Acetaminophen. Amanita phylloides. Toxins. Autoimmune. Wilson. Ischemia. Rarely tumour/Budd-Chiari
- Presentation: Encephalopathy (ABC, intubate if PSE III, IV), jaundice, fever, hypotension, hypoglycemia, coma
- The only active management -> EtOH, autoimmune, herpes viruses, Amanita (silibylin!)
- Testing: CBC, lytes, Cr!, glc!, PT, INR, alb, LFTs, ->
- Virus (A IgM, B sAg sAb eAg cIgM, C Ab +- RNA, D Ab (?) delta factor test, E Ab.)
- EtOH/Acetaminophen levels
- ANA SMA SPEP/QI
- Ceruloplasmin. 24 h U Cu
- TOX
- EBV/CMV if indicated
- US + doppler
- CT
- Glucoscans
- ICU admit
- +- Bx
- King's College Criteria!!
- Acetaminophen -> pH<7.3 OR all of INR>6.5, Cr>300, PSE III +
- Non-acetaminophen -> INR > 6.5 OR 3 of INR>3.5, Bili > 300, Jaundice to coma > 7 d, non-viral cause, age <10 or >40
- Mx:
- Neurovitals -> follow for ICP
- Lactulose oral/NG 30 q2 or enema 300+700
- NAC! You are not giving enough NAC!!! 150 x 30 min, 50 x 4 h, 100 x 16 To all until *Acetaminophen level obtained
- Glucoscans +- glucose
- Limit fluids <500 cc/d
- Check CAMPi
- Mannitol/Hyperventilation
- No hepatotoxins/nephrotoxins/sedatives
- Consider Abx
- Tx WU -> Consults: ICU/Tx/Toxicology
- Survey for infection/sz
- Nutrition
- Pressors
- Transplant
- Wilson's -> support, DPA (nephrotoxicity, rash, SJ, membranous, PPT neurol), Trientine (PPT neurol), TMP, Zn 50 q 4. Low Cu diet (shellfish, peanuts, mmm chocolate), PLEX and MARS??
HRS
- 5 Major: >133 (1.5)/<40, Hepatic disease, No nephrotoxins/sepsis/obstruction, No proteinuria, No response to 1.5L
- 5 Minor: No hematuria, low Uo<500/d, U Na < 10, U Osm > S Osm, S Na < 130
- Mx: admit, NS, U lytes/osm, S osm/lytes/Cr, Abd US, CAMPi, GLC, LFTs/INR/Bili/Alb
- Midodrine 2.5 q8h -> 7.5 q 8h titrate to HR 90
- Octreotide 50/h
- Albumin 300 cc/d (SBP dose = 1.5 g/kg day 1, 1 g/kg day 3)
- Terlipressin (for article)
- PTX
- NAC
- MARS
- Transplant
