HIV-HCV Co-Infection
Case
45 yo HIV-HCV male Risk Factor- IDU- still active Used ETOH in the past now the occasional
bender
HIV- Atripla x 6 years Episodes of treatment interruption but when on
ARVs, rarely misses
CD4- 450 HIV RNA- <40
Case
Likely HCV-infected in early 20’s Genotype 1 HCV RNA 7.8 x 105IU/mL Received Peg-IFN / RBV in 2007 but interrupted
after 6 weeks for poor tolerance and a ‘bender’ (RNA declined by about 2 logs at week 4)
Bx in 2006 suggested stage 2 fibrosis but poor
quality and during a period of excess alcohol use
No Fibroscan performed but APRI 1.8
Case
Patient is a daily MJ users and frequently takes
‘liver cleansing’ remedies
Has a longstanding PPI prescription which he
uses PRN for GERD
Case
Patient wants therapy now…. Key questions:
What are the DAA treatment options? What are the DDI concerns? What is the best fibrosis assessment modality? What about re-infection risk? Are HCV treatment outcomes really as good in HIV-
HCV co-infection as they are in HCV mono-infection?
Canadian HIV/Hepatitis C Management and Treatment Guidelines CIHR CANADIAN HIV TRIALS NETWORK (CTN)
- Similar mx in HIV-HCV as HCV mono-infection
- Anticipated SVR rates in HIV-HCV co-infection
are similar to HCV mono-infection with interferon- free, DAA regimens
- Carefully evaluate for DDIs before and during
treatment
- Select ARVs in anticipation of subsequent HCV
DAA treatment
- Discuss harm reduction strategies in those at risk
for HCV exposure
- Active injection drug use
- MSM
Key Co‐Infection Regimens
- Sofosbuvir + daclatasvir
(ALLY‐2) (N=203)1
- Grazoprevir + elbasvir

Impact of DAA Regimens on Co-Infection Guidelines
Priority shifts from early HIV treatment to early HCV treatment Fewer contraindications for HCV treatment Target populations for HCV antiviral tx is expanded Issues related to DDI reduced Benefits for Patient-Health Care Team relationship Increased network of HCV treaters
Barriers
Concentration of Barriers to Engagement and
Treatment Success
Socioeconomic Mental Health Substance Abuse Stigma Diverse populations within the HIV community
