Outline
• Cirrhosis• Cirrhosis assessment• Cirrhosis care:
• Varices: bleed prophylaxis• Ascites care• Cirrhosis “health care maintenance”
• Transplantation• When to refer• Special circumstances
• PPH, HPS• HCC
Do you have cirrhosis?
• Clinical diagnosis• Platelets, albumin, bilirubin, INR• Imaging—usually CT or MRI
• Liver biopsy• Serum Marker Scores• Non-invasive ‘imaging’
Liver biopsy
• Percutaneous or transjugular• Same day procedure• 30% chance of pain• Mild/moderate bleed risk: 1/500• Severe bleed: 1:5000• Death: 1:10,000

Serum Marker Scores
Bedossa P, et al. Clin Liv Dis 2015
Performances: ROC’s in the 0.80 range for determining advanced fibrosis/cirrhosis
Non-invasive ‘imaging’ techniques
Fibroscan performance: ROC’s 0.87-0.98 for determining advanced fibrosis/cirrhosis
Transient Elastography
• Ultrasound transducer probe• On same axis as narrow vibration source
• Pulse vibration creates elastic shear• Probe reads vibration return or echo
• Stiffness of tissue increases velocity of return.

Liver biopsy
Transient Elastography
When to use these tests
• When the underlying diagnosis is clear and cirrhosis, yes/no is all that is needed.
• Staging for hepatitis C therapy• Monitoring patients on methotrexate• Older or frail patient population• Step-wise approach with liver biopsy as a back-up• Deciding on whether cirrhosis care testing is needed.
Cirrhosis: Clinical Severity
• MELD• MELD-Na• Childs-Pugh• Nutritional / functional status
MELD
• INR, total bilirubin, creatinine• Predicts 3 month mortality risk• Developed to predict survival after TIPS• ROC curve ~ 80%
Transplant referral?
MELD-Na: the importance of hyponatremia
• Deranged hemodynamics• Increased plasma renin/angiotensin• SIADH
• Decreased free water clearance• Hyponatremia
“In patients with liver disease, serum Na levels below 130 mEq/L must be regarded as serious and, if below 125, ominous.”
• Dame Sheila Sherlock, 1956
MELD-Na: the importance of hyponatremia
• Predictive of mortality beyond just MELD especially at MELD scores <20-22
• MELD-Na = MELD score + 1.59 (135 – serum Na).

Non-selective Beta Blockade• Agents (dose low and slow)
• Propranolol• Nadolol• Carvedilol
• Target • 25% fall in heart rate or• Highest tolerated dosing to get heart rate in the 60’s
• Stop the beta blocker• Refractory ascites• Spontaneous bacterial peritonitis• Hepatorenal syndrome.

Ascites Management
• Furosemide• 20-40 mg/d• Max: 160 mg/d
• Spironolactone• 100 mg/d• Max: 400 mg/d
• Large volume paracentesis• Over 3-5 liters give 8 g/L 25% albumin (25g/3 liters taken)• Give it for first 3-5 liters in the setting of renal insufficiency or hyponatremia
Runyon, BA. AALD Guidelines 2012
Ascites Management
• Dietary advice• Low Na diet: <2 g/d• Fluid restriction: 1.8-2.0 L/d free water
• How much fluid to withdraw a LVP: more art than science
• Spontaneous peritoneal peritonitis• Diagnostic tap recommend for any hospitalized cirrhotic with ascites• 1st choice: cefotaxime; 2nd : fluoroquinolone• Albumin must be given (1.5 g/kg day 1; 1.0 g/kg day 3)

• Index decompensatory event• Encephalopathy• Variceal bleed• Ascites
• Other
Exceptional cases: Referrals when MELD may be low

Hepatocellular Carcinoma• Milan criteria or “5-3-3” rule or TMN </=T2
• One tumor < 5 cm or…• Up to 3 tumors, but…• All < 3 cm.
Stage ScoreT1(one lesion < 2cm)
No upgrade
T2(over T1 but less than “5,3,3” Milan criteria)
22*
*Score increased every 90 days to reflect 10% increase in drop-out.
Hepatopulmonary Syndrome
• Hypoxia due to intra-pulmonary shunting
• Screening• Pulse oximetry—
• Diagnosis• Doppler echocardiogram with
bubble study• RA ABG• Rule out other causes for hypoxia
Rodriguez-Roisin R, Krowka MJ. NEJM 2008
Hepatopulmonary syndromeAllocation of exception points for hepatopulmonary syndrome.

Portopulmonary Syndrome
Diagnostic Criteria:MPAP > 35 mm HgPVR > 240 dynes/sec/cm(-5)Transpulmonary gradient > 12 mm Hg
Qualification for MELD of 22:FDA approved therapy results in the following:
MPAP < 35 mm Hg and PVR < 400 dynes/sec/cm-5Satisfactory right ventricular function exists (center-specific testing).
Liver-Lung Disorders: Bottom line
• If cirrhotic patient complains of shortness of breath, consider…• Pulse oximetry• Echocardiogram with Doppler and bubble study.
A few last notes “from the trenches”…
• No NSAIDs in cirrhotics• How to give lactulose• We don’t biopsy for HCC lesions much anymore.
Thanks for listening…
