Background
HIV accelerates the natural course of hepatitis particularly
with declining CD4 counts1
Liver disease associated with HCV infection has become
a leading cause of morbidity and mortality among
HIV-infected patients

Mechanism of the effect of HIV on the
progression of hepatitis C
HIV may increase HCV replication and fibrogenesis via TGF 11.
Enhanced intrahepatic inflammatory cytokine response could be
the main cause of accelerated progression2.
Increases in profibrogenic cytokine expression and secretion,
generation of enhanced oxidative stress, and increases in
hepaotcyte apoptosis which may be further augmented in the
presence of increased microbial translocation in the setting of
HIV.
Impaired IL-2 secretion of CD4+ T cells resulting in an ineffective
stimulation of anti-fibrotic NK cell function4.
Altered levels of matrix metalloproteinases; HIV-associated gut
depletion of CD45

ART and SVR to HCV therapy are associated with slower
liver fibrosis progression in HIV-HCV-coinfected patients:
study from the ANRS CO 13 HEPAVIH cohort.
Methods:
HIV-HCV-coinfected adults enrolled in the ANRS CO 13
HEPAVIH cohort, for whom two results of LS, evaluated over
24 months, were available.
Results:
In multivariate linear and logistic analyses, excessive alcohol
intake ( coefficient 6.8; P=0.0006) and high HCV viral load
(OR 1.7, 95% CI 1.1, 2.5; P=0.01) were independently
associated with an increase in LS, whereas time on
ART>114.5 months (OR 0.5, 95% CI 0.3, 0.9; P=0.03) and
achievement of sustained virological response (OR 0.1, 95%
CI 0.01, 0.9; P=0.04) were independently associated with no
increase in LS.

The changing pattern of glomerular disease in HIV
and hepatitis C co-infected patients in the era of
HAART1
ART is associated with lower post-IFN HCV-RNA
levels; that change is linked to reduced hepatic
interferon stimulating gene (ISG) expression; these
data support recommendations to provide ART
prior to IFN-based treatment of HCV

Effects of ART on the liver in HIV/HCVcoinfected patients: Conclusions
The short- and mid-term effects of ART on the
progression of HCV-related liver disease largely
outweigh the potential risks for long-term toxicity.
This supports an earlier starting of ART in patients with
HIV/HCV-coinfection.
However, surveillance of possible new side effects, as
well as of changes in the natural history of hepatitis C
infection in patients on HAART is required.
SVR does not only decrease liver disease associated
morbidity and mortality but also overall survival and this
for all fibrosis stages
