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

HIV-HCV Coinfection

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

HCV Is a Sexually Transmitted
Disease Among HIV-Infected MSM
• HIV-positive MSM
diagnosed with recent
HCV (N = 226) between
2000 and 2006
• NS5B sequences were
obtained
– Phylogenetic analysis
revealed 156 (78%)
sequences that formed
11 clusters

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.

Case 4
• 48-year-old man with HIV/HCV coinfection
– HIV is well controlled on DRV/r + TDF/FTC (first
regimen)
– HCV genotype 1A
– HCV RNA ~ 3.4 million IU/mL
– Liver biopsy: Stage 2 fibrosis
• The patient asked if he is a candidate for the
new HCV protease inhibitors
27
Question
Which of the following statements regarding firstgeneration HCV NS3/4A protease inhibitors is
NOT correct?
A. Drug-drug interactions with antiretroviral
agents may occur
B. HCV variants resistant to these agents may
be selected during therapy
C. Ribavirin need not be administered in
combination with these potent agents
D. Anemia is a potential side effect
28
Protease Inhibitor + Peg-IFN + RBV
• Boceprevir 800 mg po tid + peg-IFN + RBV
– Start with peg-IFN/RBV x 4 weeks “lead-in”
– Add BOC for 24 or 44 weeks, depending on
HCV RNA response at treatment week 8
– AEs due to BOC: anemia, dysguesia
– Resistant variants selected with treatment failure
(same variants as telaprevir)
– Drug-drug interactions likely
– No data in HIV/HCV
BOC = boceprevir.

Boceprevir: Metabolism and DrugDrug Interactions
• Substrate of aldoketoreductase  primary pathway
• Substrate of CYP3A4/5
– Coadministration of EFV (CYP3A4/5 inducer)
decreased BOC mean exposure 19% to 44% and
increased efavirenz mean exposure 11% to 20%
– No RTV boost
• Strong CYP3A4 inhibitor without evidence of
induction
‒ BOC  Midazolam AUC markedly increased
• Substrate for the efflux inhibitor P-glycoprotein (P-gp)
• No drug-drug interactions with tenofovir
AUC = area under the curve.
Kasserra C et al. CROI 2011. Abstract 118.
31
Protease Inhibitor + Peg-IFN + RBV
• Telaprevir 750 mg po tid + peg-IFN + RBV
– Start with TVR + peg-IFN/RBV  stop TVR
after 12 weeks
– Total duration of therapy of 24 or 48 weeks depending
on HCV RNA response at treatment week 4
– AEs due to TVR: anemia, rash
– Resistant variants selected with treatment failure
(same variants as boceprevir)
– Drug-drug interactions likely
– Limited data in HIV/HCV

Asian-Pacific guidelines
• Preferred regimen
– Tenofovir* 300 mg/day
– Entecavir* 0.5 mg/day (wild-type HBV); 1 mg/day
(lamivudine-resistant HBV)
– Peg-IFN alfa
*In HIV+ persons, both tenofovir and entecavir
must be used with a fully suppressive
antiretroviral regimen.

• 63-year-old man with chronic HBV, HIV disease,
hypertension, and type 2 DM
– Fully suppressed HIV on regimen of
EFV/TDF/FTC
– Serum creatinine has increased; his nephrologist
recommends modifying TDF to lower dose
– HBV DNA detectable, 950 U/mL

Role of Entecavir in HIV/HBV
Coinfection
• ETV should be reserved for the patient in whom
TDF is contraindicated
– Less effective for lamivudine-resistant HBV
compared to wild-type due to cross-resistance
– Use with fully-suppressive ART regimen
• Limited data in combination with TDF
– No HBV cross-resistance between TDF
and ETV
60
Summary
• Hepatitis C
– Screen all persons; repeat annually if
seronegative
– Evaluate all HCV-antibody-positive persons
– Consider HCV treatment with peg-IFN/RBV or
telaprevir + peg-IFN/RBV
• Hepatitis B
– Screen all persons; vaccinate if seronegative
– Evaluate and screen all HBsAg-positive persons
– Treat both HIV and HBV with fully suppressive
ART with TDF + FTC or TDF + 3TC
