X. Medical imaging:
Ultrasound of the abdomen was obtained. The liver had a heterogeneous echotexture, but did
not appear nodular. No focal liver lesions. The hepatic and portal veins appeared patent by
2
Doppler. Large amount of ascites noted. Gallbladder is normal. Spleen is absent. Kidneys are of
normal size and echogenicity, no hydronephrosis.
XI. Follow up
Visit A- Initial intervention
The patient underwent an 8.1 L paracentesis with albumin replacement. Ascitic fluid analysis
revealed an ascitic fluid protein of 1.0, albumin < 1.0, WBC 35. Ibuprofen was stopped, she
received diet counseling for a 2 gram Na restricted diet. Spironolactone 100 mg daily and
furosemide 40 mg daily were started.
Visit B- Two months follow up
She presents for follow up 2 months later. She has been abstinent of alcohol. Ascites is
controlled on diuretics. The following laboratory tests are obtained on follow up.

Visit C- One month later
RF continued to be well until about 1 month after her follow up visit when she started developing
leg swelling, followed by increased abdominal distention and confusion progressing over 5 days
prior to presentation. She is brought to the ED by her husband who reported that she has not
been drinking alcohol and has been taking all of her medication as instructed. She has not had
fever or chills. No cough or shortness of breath or headache. No urinary symptoms. She has
been complaining of a mild abdominal discomfort and nausea and has a reduced oral intake
over the past 48 hours.
Vitals BP110/65, Pulse 88, RR 14, Temp 99.2
She is icteric, has a distended abdomen with flank dullness, +2 LE edema, she opens her eyes
when her name is called. She responds to questions with an incomprehensible mumbling. Milk
maid sign is positive.

Issues for contemplation
A. Initial Presentation
 Discuss the finding of a distended abdomen on exam in our patient and the
diagnostic accuracy of physical exam maneuvers in identifying ascites as a
cause of abdominal distention.
 What other physical exam findings would you look for that would help you with
the differential diagnosis?
 What is your assessment of the patient’s alcohol intake? What other elements of
history would you like to obtain to ascertain whether the patient has signs of
alcohol dependence?
 Discuss the abnormalities in liver associated enzymes, markers of liver synthetic
function, and CBC on presentation in our patient and how this helps you in
formulating a differential diagnosis for the cause of her symptoms.
 Discuss the finding of a low Ferritin level on initial evaluation.
 What was the significance of a positive hepatitis C antibody? What are the
sensitivity and specificity of this finding in detecting a chronic hepatitis C
infection?
 What are the risk factors for chronic hepatitis C? Who should be screened for this
infection in the general population?
 What is the likely mode of transmission of HCV to our patient?
 What are the factors associated with a severe liver injury due to hepatitis C?
 Discuss the clinical significance of a positive ANA and elevated IgG fraction in
our patient.
 Are there additional tests that you like to obtain at the time of the initial evaluation
of our patient?
 Are there additional management interventions that you would recommend after
initial evaluation?
B. Hepatitis C management
 What is the current standard of care in treatment of hepatitis C infection and
the expected outcome of treatment in the general population of infected
patients?
 What are the potential adverse effects of the standard of care treatment?
4

What are the risks and benefits of HCV treatment in the case of our patient at
initial presentation and at the time of the first follow up visit.
C. Presentation to the ED
 What is your interpretation of the patient’s history and physical exam findings at
presentation to the ED?
 What is your interpretation of her laboratory tests on presentation?
 What is your differential diagnosis for this acute illness? Are there findings on her
initial evaluation and testing that suggest that she is a risk for a specific
complication?
 What would you initial steps in management be?
 Assuming that, after an initial diagnostic evaluation and treatment, three days
after the initial presentation, her mental status is improved, bilirubin is reduced to
4.0 and INR to 1.7, but Creatinine continues to rise and is now 3.6. She is
making about 80 cc of urine per day. How would you evaluate the renal further?
What are the next steps in management?
 What is her long term prognosis, and how does this affect your management
decisions?
