Slide 9 of 33 Alternatives to liver biopsy Alternative approaches – Serum markers Standard laboratory tests: APRI, FIB-4 Commercial assays – Radiographic tests Elastography Limitations – Ability to distinguish F1 versus F2, etc Better to differentiate advanced versus early – Serologies impacted by inflammation – Indeterminate outcomes common Lin ZH.

Slide 10 of 33 Recommendations AASLD/IDSA/IAS–USA Guidance – An assessment of the degree of hepatic fibrosis, using noninvasive testing or liver biopsy, is recommended. Ongoing assessment of liver disease is recommended for persons in whom therapy is deferred.
Treatment
Slide 12 of 33 Who needs treatment? AASLD/IDSA/IAS–USA Guidance – Treatment is recommended for patients with chronic HCV infection. Treatment is assigned the highest priority for those patients with advanced fibrosis (Metavir F3), those with compensated cirrhosis (Metavir F4), liver transplant recipients, and patients with severe extrahepatic hepatitis C.

Decompensated Cirrhosis

Slide 33 of 33 Summary All patients with HCV need an assessment of fibrosis – Patients with advanced fibrosis or cirrhosis should be prioritized for treatment HCV treatment is safe and effective in patients with compensated cirrhosis – Sofosbuvir and ribavirin are effective for genotype 2/3 – Multiple interferon-free regimens have been developed for genotype 1 – Adverse events are generally mild with interferon-free regimens – Interferon-free regimens are well tolerated by patients with decompensated cirrhosis, and the long-term effectiveness is under investigation
