Clinical Perspectives and Best Practices in the Management of HIVInfected Patients With Hepatitis Coinfection Educational Objectives • Describe clinical considerations that require assessment in HIV-infected individuals with hepatitis coinfection • Assess the impact of HIV/hepatitis coinfection on hepatic function and on treatment-related adverse events • Describe evidence-based recommendations for the management of HIV-infected individuals who have coinfection with hepatitis B or C 2 HIV-HCV Coinfection 3 Case 1 • 60-year-old man with long-standing HIV disease – ART with undetectable HIV RNA ~ 10 years • Laboratory testing was performed following a routine office visit – – – – ALT = 1390 U/L (was 26 U/L 3 months ago) HCV EIA + (was negative ~ 5 years ago) HCV RNA = 1.3 million IU/mL HCV genotype 1A ART = antiretroviral therapy; ALT = alanine aminotransferase; EIA = enzyme immunoassay. 4 Question In which of the following scenarios is screening with HCV RNA indicated? A. Patient with normal ALT and negative HCV EIA B. Patient with new elevation in ALT to 3 x ULN and negative HCV EIA C. Patient with CD4 cell count ~ 25/mm3, elevated ALT, and negative HCV EIA D. Patient with newly diagnosed HIV and no prior HCV testing E. B and C 5 HCV Coinfection Is Detected in About One-Third of HIV-Infected Patients Prevalence Is Highest Among IDUs Prevalence (%) 100 85 80 N = 1955 60 45 40 14 20 10 0 IDU Heterosexual Male Entire Contact Homosexual Cohort Contact IDU = injection drug user.

Reprinted with permission. © 2009. 7 Acute Hepatitis C in HIV-Infected Patients Should Be Routinely Treated • 53 HIV-infected persons with acute HCV infection – 28 genotype 4; 14 genotype 1; 7 genotype 3 • Better outcomes were achieved with early treatment with peg-IFN + RBV – Spontaneous clearance occurred in ~ 16.5% – Treatment-induced clearance (sustained virologic response) occurred in ~ 82.1% (32/39) peg-IFN = peginterferon; RBV = ribavirin. Piroth L et al. Hepatology. 2010;52:1915-1921. 8 HCV in HIV-Infected Patients • Universal screening (independent of risk behaviors) – IDU and blood exposure > sexual transmission – Screen with HCV EIA; consider HCV RNA screening in unique situations (eg, acute disease) – If EIA negative, re-screen annually with EIA • Repeat testing with high-risk exposure and/or increase in serum ALT 9 Case 2 • 58-year-old African-American woman with wellcontrolled HIV disease (EFV/TDF/FTC) • HCV acquired via IDU ~ 41 years prior (inactive for many years) – ALT level ranges from 45 to 75 U/L – No symptoms 10 Question Which of the following assessments should be routinely performed on all HIV-infected persons who are HCV EIA positive? A. Hepatitis A antibody total B. HCV RIBA C. HCV RNA, quantitative assay D. GGT E. A and C RIBA = recombinant immunoblot assay. 11 Evaluation of HCV in Persons With HIV Infection • Confirm chronic infection with HCV RNA testing (quantitative assay) – No role for qualitative RNA assay or RIBA • HCV genotype • Assess liver function: platelet count, total bilirubin, INR, creatinine • Fibrosis staging to assess “need” for therapy – Liver histology – Serum marker – Transient elastography INR = international normalized ratio. 12 Effect of HIV on HCV Natural History HCV Infection Chronic HIV/HCV Coinfected Less Spontaneous Clearance More Chronic More Cirrhosis Cirrhosis More ESLD, HCC ESLD, HCC ESLD = end-stage liver disease; HCC = hepatocellular carcinoma. 13 Cirrhosis (%) Impact of HIV on Liver Disease Progression With Chronic HCV 0 5 10 15 20 25 30 Years Thein H-H et al.
