III,IV, and VIII - not effected by liver disease

89
Q

Gold standard to diagnose portal hypertension

A

Insert catheter to get pressure

90
Q

ABCDE of portal hypertension

A

Ascites
Bleeding
Caput Medusae
Diminished liver function
Enlarged spleen

91
Q

Hepatorenal syndrome

A

Liver failure leads to kidney failure - portal hypertension causes poor perfusion of kidneys

92
Q

Hepatic encephalopathy

A

Due to ammonia buildup - ammonia can’t be made to urea

93
Q

3 enzymes that assess for hepatic tissue damage

A

AST, ALT, LDH
ALT is the most specific to the liver

94
Q

Elevated aminotranseferases indicating acute liver trauma

A

8-25x normal range
AST>ALT (ratio over two - chronic alcohol, under two non-alcoholic)
ALT>AST - Acute Liver Trauma

95
Q

2 Liver enxymes to measure obstruction of the billiary tre

A

Alkaline phosphatase (4x elevation is cholestasis) AND Gamma-glutamyl transpeptidase
BOTH is indicative of obstruction
Also 5’-nucleotidase specific to the liver

96
Q

Tests of hpatic synthetic function

A

Albumin levels
If other LFTs are normal consider malnutrition
PT time
See above note

97
Q

Autoimmune hepatitis

A

Insidious onset to sudden attack presentation
Precipitated by viral illness, pregnancy, drug exposure
May have a history of autoimmune - Positive ANA, pANCA, anti-SLA
Liver biopsy for diagnosis

98
Q

Treatment for autoimmune hepatitis

A

Prednisone long term
Azathioprine - second line
Liver transplant if they fail therapy

99
Q

Drugs that can induce hepatitis

A

Acetominophe
Isoniazid
Tetracyclines

100
Q

Labs and treatment for drug induced hepatitis

A

ALT > AST
May require a liver transplant

101
Q

Acetominophen toxic doses for kids and adults

A

Adults - 4g (4000mg)
Kids - 80mg/kg

102
Q

Stage one of acetominophen induced hepatitis

A

.5-24 hours - N/V, diaphoresis, pallor lethargy w/ normal labs

103
Q

Stage two of acetominophen induced hepatitis

A

24-72 hours
Symptoms resolve but labs get worse
RUQ pain
PT and billirubin elevated

104
Q

Stage three of acetominophen induced hepatitis

A

72-96
Jaundice, confusion
Elevated enzymes
Many die

105
Q

Stage 4 of acetominopheni induced hepatitis

A

4 days to 2 weeks
Recovery
May have AKI
Symptoms and lab values begin to normalize

106
Q

Diagnosis and treatment for acetominphen induced hepatitis

A

Measure acetominophen level with the blood
N-acetylcysteine (activated charcoal) if possible within 1-2 hours of ingestion - give if we don’t know when they took it

107
Q

RiskFactors for Alcoholic liver disease

A

2 drinks per day for men, 1 per day for women
Fatty liver to alcoholic hepatitis to cirrhosis
50g daily for 10 years is the threshold
Often an incidental finding of labs in the fatty liver stage

108
Q

ALT AST ratio of alcoholic liver disease

A

2:1 or greater AST to ALT ratio

109
Q

Treatment for alcoholic liver disease

A

Abstinence from alcohol
Folic acid, zinc, thiamine
Prednisone for about a month

110
Q

Glasgow alcoholic hepatitis score

A

Greater than 9 is an indication for steroid treatment

111
Q

Non-alcoholic steatohepatitis

A

Fatty liver w/o alcohol us
Can still lead to cirrhosis
Fatty liver is without inflammation
RUQ discomfort - vague symptoms
Biopsy to diagnose

112
Q

Treatment for non-alcoholic fatty liver disease- 5

A

Lifestyle modification
Hepatitis vaccines
Vitamin E, Thiazolidenediones, Metformin
