Pathogenesis of HE
Number of theories had been proposed for
the development of Hepatic Encephalopathy
 Ammonia Hypothesis
 Most popular
 GABA Hypothesis
 False Neurotransmitter Hypothesis
Causes of Hyperammonemia
Hyperammonemia
HE
• GI bleeding
• Azotemia
• High protein intake
• Constipation
• Bleeding into tissue
• Infection, sepsis
• Catabolism/
muscle atrophy
• Azotemia
• Lack of scavenger cells
• Portocaval anastomoses
• Metabolic insufficiency
• Acidosis
• Diuretics

What is the grade of hepatic
encephalopathy?
a. Grade 1
b. Grade 2
c. Grade 3
d. Grade 4
Grade 0
Clinically normal mental status but minimal changes in memory,
concentration, intellectual function, and coordination
Grade 1
Mild confusion, euphoria, or depression; decreased attention;
slowing of ability to perform mental tasks; irritability; and
disordered sleep pattern, such as inverted sleep cycle
Grade 2
Drowsiness, lethargy, gross deficits in ability to perform mental
tasks, obvious personality changes, inappropriate behavior, and
intermittent disorientation, usually about time
Grade 3
Somnolent but can be aroused, unable to perform mental tasks,
disorientation about time and place, marked confusion, amnesia,
occasional fits of rage, present but incomprehensible speech
Grade 4
Coma with or without response to painful stimuli.
Grading of symptoms (West
Haven scale)
What is the initial step in the
management of hepatic encephalopathy?
a. empty bowels of nitrogen-containing substances by
giving lactulose
b. Administer non-absorbable antibiotics e.g.
metronidazole or rifaximin
c. Administer intravenous BCAAs
d. Identify precipitating factor
e. all of the above
Glucagon-Insulin therapy
Artificial liver support system
e.g. plasma exchange,
hemofilitration, hemodialysis
Identify precipitating factor
e.g. hemorrhage, large protein meal, infection
electrolyte imbalance, sedatives
Qualifying and quantifying protein intake
First step
Second step
Third step
Empty bowels of nitrogen-
containing materials
lactulose (per os and/or enema)
BCAA- enriched Amino acid
infusion
Management of HE
Goals for the treatment of Overt HE
(OHE)
Acute episode of of HE 1. Treatment of precipitating
factors
2. Improvement in mental status
3. Evaluation for liver transplant
Out-patient management after
an episode of HE
1. Prevention of recurrent episodes
of HE
2. Improvement of daily
functioning
3. Evaluation for liver transplant
Bajaj, JS et al, Aliment Pharmacol Ther.2010;31(5): 537-547.
Management of Acute OHE
• Overall management consists of properly identifying
OHE
• Severity
• Treating potential precipitating factors
• Specific treatment interventions
• Leading precipitating factors:
• GI bleeding
• Sepsis
• Dehydration (diuretics, diarrhea or vomiting)
Bajaj, JS et al, Aliment Pharmacol Ther.2010;31(5): 537-547.
Specific treatment interventions
Specific
intervention
Mechanism of Action Dose Comments
1. Nonabsorbable
disaccharides (e.g.
Lactulose, Lactitol)
1. Laxative
2. Interfere with the
mucosal uptake
of glutamine
therefore reduces
the synthesis and
absorption of NH3
15-30 cc 2x daily
to induce 2-3
bowel
motions/day

2. Non-absorbable
antibiotics

metaanalysis
Out-patient treatment after an
episode of HE
• Prevention of recurrent episodes is key to
normalization of daily functioning
• Lactulose(1)
• Sharma et al showed that it significantly reduced
recurrent HE episodes compared with placebo
• Rifaximin(2)
• A recent trial by Bass et al, showed that Rifaximin
(550mg BID) with Lactulose was more effective
than Lactulose alone in the prevention of HE
episodes in patients with >2 or more HE episodes
in the past 6 months

2. Bass NM, et al. J Hepatol 2009;50(S1): 539.
Other Out-patient treatment options
after an episode of HE
• Zinc repletion (zinc sulfate and zinc acetate, oral
dose of 600 mg)
• Bromocriptine (oral dose of 15-60 mg daily)
• Sodium benzoate (oral dose of 5g twice daily)
• L-ornithine L aspartate (LOLA)
(oral dose of 6 g thrice daily)
• Vegetable-based protein
• BCAA-enriched diet
Prakash, R et al. Nat.Rev. Gastroenterol. Hepatol , 2010, 515-525
BCAAs supplementation after an
episode of HE
• RCT, 4 tertiary care hospitals
• Population: 116 cirrhotic patients with a previous
episode of HE
• Intervention: All patients received a standard diet of
35 kcal/kg/day and 0.7g CHON/kg/day and a
supplement of 30g of BCAA (BCAA group) or
Maltodextrin (MDX group) for 56 weeks
• Outcome: actuarial risk of remaining free of HE
Les I, et al. American J of Gastroenterol june 2011;106: 1081-1088
BCAAs supplementation after an
episode of HE
• Results:
• Actuarial risk of remaining free of HE did not
differ between groups
(BCAA= 47% vs MDX= 34%, p=0.274)
• BCAA group exhibited better outcome on
neuropsychological tests
• BCAA group had an increase in mid-arm muscle
circumference
Les I, et al. American J of Gastroenterol june 2011;106: 1081-1088
Going back to the case…
• Patient was admitted to ICU and was given the
following medications:
• Lactulose 30 cc to induce 2-3 BM/day
• Rifaximin 550 mg BID
• IV BCAA later shifted to oral BCAA
• Vasopressin analogue for control variceal
bleeding
• He was subsequently transferred to regular room on
the 5th HD and subsequently discharged on the 8th
HD improved and stable.
In the interim …
• JM is being managed at home with his usual
medications. He has fair appetite.
• Pertinent PE:
• Grossly hyposthenic, slightly icteric
• BMI: 18 kg/m2
• Grade 2 bidepal edema
• (+) ascites
In the interim …
• Pertinent laboratory tests:
• WBC: 3.5, Hgb: 10
• Lymphocytes: 20
• Albumin: 2.2
• TB: 3.0
Do you think he has protein-calorie
malnutrition?
• a. Yes
