From S Naggie, MD, at New York, NY: March 23, 2016, IAS-USA.
Learning Objectives
After attending this presentation, participants will be able to:
 List the options for assessing liver fibrosis
 Describe the AASLD/IDSA Guideline recommendations
for management and treatment of HCV Infection
 Describe the drug interactions with antiretrovirals and
HCV direct acting antivirals (DAAs)
 Describe treatment plans for difficult to treat patients,
including those with cirrhosis and NS5A drug resistanceassociated viral variants

Staging of Liver Disease:
Liver Biopsy
• Gold standard
• Invasive
- Morbidity (3/1,000)
- Mortality (1/10,000)
• Observer variability
• Sampling error
• Costly

Alternatives to Liver Biopsy
►Noninvasive approaches
– Serum markers
• Standard laboratory tests: APRI (<0.3,>2), FIB-4 (>3.25)
• Commercial assays (FibroSure) (>0.8)
– Radiographic tests
• Elastography
►Limitations
– Ability to distinguish F1 versus F2, etc.
• Better to differentiate advanced versus early fibrosis
– Serologies impacted by inflammation
– Indeterminate outcomes common

Radiographic Assessments
Newer Methods
► Ultrasound, CT, MRI
– Conventional studies are unhelpful in assessment of fibrosis
unless patient has decompensated cirrhosis
► Elastography
► Transient elastography
– Methodology
• Ultrasonic transducer sends a vibration wave into the liver
• Elastic shear wave propagates through the liver
• Velocity of wave correlates with tissue stiffness
– Test characteristics
• Mean AUROC for the diagnosis of:
– Severe fibrosis: 0.89 (95% CI, 0.88-0.91)
– Cirrhosis: 0.94 (95% CI, 0.93-0.95)

►Baseline viral load can predict decrease
risk of relapse
►Real World Cohorts
– TRIO – 242/254 (95%)
CON
►Baseline viral load is not the
only predictor and has poor
accuracy
►Real World Cohorts
– VA – greater failure for 8 weeks
in black veterans
– TARGET – 150/154 (97%)
– GECCO – 175/191 (92%)
– Only ~40% of TARGET eligible
