(40 cards)
Chronic hepatitis characterized by circulating autoantibodies (not thought to be part of the pathophysiology) & high levels of serum globulin concentrations
autoimmune hepatitis
Treatment for autoimmune hepatitis
corticosteroids. azathioprine 2nd line
Genetic disease due to autosomal recessive gene HFE. Most common single gene disorder
hemachromatosis
Increased iron load leads to eventual cirrhosis, cardiomyopathy, DM, and hypogonadism
hemochromatosis
When do symptoms of hemochromatosis usually present?
age 40 or when iron stores reach 15-40g
Classic presentation of hemochromatosis
cutaneous hyperpigmentation w/ diabetes & cirrhosis
Gold standard for confirmation of hemochromatosis in addition to elevated serum transferrin saturation and elevated serum ferritin
liver biopsy
The mainstay of treatment for hemochromatosis is phlebotomy. What lifestyle modifications should a patient also make?
avoid red meat, Fe vitamins, ETOH, and the handling/eating of raw seafood. Get Hep A&B vaccines
Autosomal recessive disease that affects copper metabolism. Organ damage due to copper build up in the liver and brain

Can occur within hours of a large alcohol binge & if continues to drink can progress. May have tender hepatomegaly. Transaminases mildly elevated. Can also occur in obese individuals and pregnancy
fatty liver
Physical exam may reveal spider angiomas, palmar erythema, gynecomastia, parotid enlargement, testicular atrophy, ascites, encephalopathy
fatty liver
Distinguishing feature of transaminases associated with fatty liver disease that is rarely seen in other forms of liver disease
AST: ALT ratio usually greater than 2:0
Histology finding associated with fatty liver disease
Mallory bodies
Treatment of fatty liver disease
alcohol cessation, glucocorticosteroids for severe cases, possible liver transplant
Most common cause of liver failure in the US
drug induced liver injury (DILI)
Common group of drugs that induce asymptomatic elevations in liver enzymes without causing disease
statins
Most common drugs implicated in DILI in US
acetaminophen and antibiotics
Treatment for acetaminophen overdose
Activated charcoal if ingested within 2-3 hours. N-acetylcysteine for severe overdose
T/F All patients with liver tenderness and jaundice secondary to acetaminophen should received N-acetylcysteine
true
General signs of viral hepatitis on exam
jaundice, RUQ pain, hepatomegaly
Viral hepatitis where there is no chronic infection and no documentation of maternal-fetal transmission
hepatitis A
