A 46-year-old obese woman presents with a 6-hour history of moderate pain in the RUQ that began after eating dinner. The severity of the pain gradually increased before reaching a constant over the last few hours. She has had previous episodes of similar pain for which she has not sought medical advice. When asked about stool patterns, she noted that her stools have been a pale gray lately. Her vital signs are normal. Her physical exam is noted for tenderness to palpation in the right upper quadrant with no guarding or rebound tenderness.How is her condition related to bilirubin metabolism?
- A.
She has an obstruction in her biliary tract causing a lack of conjugated bilirubin in the intestine.
- B.
She has an excess of urobilinogen due to bile duct obstruction
- C.
She has a lack of albumin, causing decreased transport of conjugated bilirubin
- D.
She has hyperactive bile ducts due to her obesity
- E.
She has gallstones blocking her bile ducts, leading to excess unconjugated bilirubin entering the intestine
Correct Answer
A. She has an obstruction in her biliary tract causing a lack of conjugated bilirubin in the intestine.Explanation
The vignette describes cholelithiasis (gallstones), which can cause the pale color stools because it prevents the conjugated bilirubin from getting into the intestine and being converted to urobilinogen.

- D.
23 year old male with mononucleosis acquired during a late night rendezvous in Ft. Lauderdale
Correct Answer
D. 23 year old male with mononucleosis acquired during a late night rendezvous in Ft. LauderdaleExplanation
The answer is D because I was going for hypersplenism caused by Mono. This was listed under the Unconjugated Bilirubin side of the chart in Dr. Cohen's lecture. The hypersplenism leads to increased production of bilirubin, which can't be cleared in the excess quantity.

A 3 week old male is seen by a neonatologist because of severe jaundice that appeared at birth and has been worsening since. He is the first born child of a healthy Jewish couple. His mother's pregnancy and delivery were uneventful. On PE he is average height and weight for his age, and in no acute distress. He has marked jaundice and slight hepatomegaly. Lab tests show markedly elevated bilirubin of 15 mg/dL and a very low fecal urobilinogen. Phenobarbital treatment is initiated, but is ultimately unsuccessful. The child dies at 6 months of age after showing signs of delayed development.What is the most likely diagnosis?
- A.
Dubin-Johnson syndrome
- B.
Gilbert syndrome
- C.
Criglar-Najjar Type 1
- D.
Criglar-Najjar Type 2
- E.
Rotor syndrome
Correct Answer
C. Criglar-Najjar Type 1Explanation
The severity of the symptoms and TB levels beginning at birth is suggestive for C-N. Because of the lack of response to Phenobarbital and the later development of kernicterus, it is likely C-N Type 1.

A 56 year old male with a history of mild, controlled Ulcerative Colitis presents with complaints of fatigue and upper abdominal pain. When asked he recalls an itching sensation on the palms and soles, and loose, pale stools, but denies fever. Physical examination is unremarkable. Which of the following sets of lab values would you expect to see in this patient?
- A.
AST 40, ALT 40, Alk Phos 50
- B.
AST 100, ALT 100, Alk Phos 500
- C.
AST 1000, ALT 1000, Alk Phos 150
- D.
AST 1000, ALT 1000, Alk Phos 500
- E.
AST 10000, ALT 10000, Alk Phos 50000
Correct Answer
B. AST 100, ALT 100, Alk Phos 500Explanation
This vignette is suggesting PSC as the origin of his symptoms, but it is also clearly showing cholestatic symptoms rather than hepatocellular. So you would expect the Alk Phos to be 3-10X normal and the ALT/AST to be 1-8X normal (from Dr. Cohen's Bilirubin lecture). Hepatocellular would be more like choice C with ALT/AST 8-20x normal and Alk Phos 1-3X normal.

An 18-year-old woman presents with bilateral tremor of the hands. She is a senior in high school and during the year her grades have plummeted to the point that she is failing. She says her memory is now poor, and she has trouble focusing on tasks. Her behavior has changed in the past 6 months in that she has frequent episodes of depression, separated by episodes of bizarre behavior, including shoplifting and excessive drinking. Her parents and other authorities have begun to suspect her of using street drugs, which she denies. Her handwriting has become very sloppy. Her parents have noted slight slurring of her speech. Physical exam reveals upper extremity tremor, mild dystonia of the upper extremities, and mild incoordination involving her hands. She is found to have elevated serum aminotransferase enzymes (AST 150 units/L, ALT 175 units/L) an elevated serum bilirubin (77.0 micromol/L(4.5 mg/dL) and Coombs negative hemolytic anemia.Which of the following would be most likely to be seen on physical exam?
- A.
Splenomegaly
- B.
Kaiser-Fleicher rings
- C.
Jaundice
- D.
Ascites
- E.
Peripheral edema
Correct Answer
B. Kaiser-Fleicher ringsExplanation
The vignette is describing Wilson's disease. K-F rings are seen in 99% of neurologically symptomatic Wilson's disease (according to epocrates). You could see jaundice or ascites with Wilson's, but it is rare. Splenomegaly and edema could also be seen with cirrhosis associated with Wilson's but again are less likely.

A 50 year old Caucasian male presents to his PCP with symptoms of chronic fatigue, weakness, lethargy, and apathy. Upon physical exam he has hepatomegaly and dark appearing skin. Lab results reveal a hemoglobin A1C of 9.5% and elevated ALT and AST. X ray shows narrowing of joint spaces. Which of the following is most accurate about the pathogenesis of his condition?
- A.
He has elevated Hepcidin levels
- B.
He has decreased Ferroportin function
- C.
He probably has an elevated Transferrin saturation level
- D.
His serum Ferritin level is likely decreased
- E.
Liver biopsy will show iron deposition in Kupffer cells
Correct Answer
C. He probably has an elevated Transferrin saturation levelExplanation
He has hereditary hemochromatosis. His hepcidin would be decreased in the setting of this disease. His Ferroportin function would be elevated because of the lack of hepcidin to hold it in check. He will have an elevated Transferrin, as that is the "earliest phenotypic manifestion of HFE-related HH." Serum ferritin would also be increased. Liver biopsy would show iron within the hepatocytes, but sparing the Kuppfer cells.

Non-selective B-blockers are an effective treatment for portal HTN because they cause mesenteric atreriolar vasodilation, thus lowering the portal pressure
- D.
Octreotide can be used to manage active variceal hemorrhage because it decreases portal pressure by decreasing glucagon release, thus decreasing portal inflow
- E.
Cirrhosis leads to decreased portal 'in' flow by constricting mesenteric arteries
- F.
All of the above
Correct Answer
D. Octreotide can be used to manage active variceal hemorrhage because it decreases portal pressure by decreasing glucagon release, thus decreasing portal inflowExplanation
D is correct, and all the others are flipped around.

Which of the following is a mechanism proposed for how ammonia causes hepatic encephalopathy?
- A.
Increases glycogen concentration in astrocytes
- B.
Enhances synaptic transmission
- C.
Enhances glial-neuronal signaling
- D.
Modulates cell signaling via GABA and Glutamate
- E.

Correct Answer
D. Modulates cell signaling via GABA and GlutamateExplanation
Decreases glycogen in astrocytes
Interferes with glial-neuronal communication and synaptic transmission
It does modulate cell signaling via GABA and Glutamate
Not all pts with HE have high serum NH4+, which is the main problem with the ammonia hypothesis

Autoimmune hepatitis
- B.
PBC
- C.
PSC
- D.
Chronic Hepatitis B
- E.
Chronic Hepatitis C

Which of the following diseases is correctly matched up with the type of hyperbilirubinemia that it causes?
- A.
Hemolytic anemia: Unconjugated hyperbilirubinemia
- B.
Gilbert syndrome: Direct hyperbilirubinemia
- C.
Cholestasis: Unconjugated hyperbilirubinemia
- D.
Crigler-Najjar: Conjugated hyperbilirubinemia
- E.
None of the above
Correct Answer
A. Hemolytic anemia: Unconjugated hyperbilirubinemiaExplanation
A: Hemolytic anemia overloads the liver's capacity to conjugate bilirubin, leading to excess unconjugate
B: GB syndrome is a deficiency of UDP-Gluc which results in a lack of conjugated BR, and hence an Indirect HyperBRemia
C: Cholestasis doesn't affect conjugation, so it would be high direct BR
D: C-N is basically a more severe Gilbert. There is almost no conjugation happening, hence it would be unconjugated BR.

A 14-year-old boy is seen in the outpatient clinic with persistent jaundice. His mother reports that jaundice has been noted since early infancy and has never completely cleared up. Some blood tests were done at that time and they were told that, apart from jaundice levels being high, the rest of the test results were all within normal limits. He was followed up for a year and then discharged as he remained well with no symptoms. His eyes have always looked slightly yellow and he has always passed dark-colored urine. The boy's mother reports that he had a chest infection recently and that since then his jaundice has looked a lot worse. He is otherwise completely asymptomatic. Physical exam is unremarkable apart from obvious icterus. Liver biopsy is normal. Lab shows Total bilirubin of 3, direct bilirubin 2.2 . What is the most likely diagnosis?
- A.
Crigler-Najjar syndrome Type 1
- B.
Crigler-Najjar syndrome Type 2
- C.
Gilbert syndrome
- D.
Dubin-Johnson syndrome
- E.
Rotor syndrome
Correct Answer
E. Rotor syndromeExplanation
This is Rotor syndrome. The elevated conjugated bilirubin should rule out A, B, and C. Between D-J and Rotor, since there is nothing on the liver biopsy, it is Rotor. D-J would have the "black liver" appearance. Rotor is usually clinically mild like this, with jaundice that is persistent but can intensify with acute illness.
