Introduction
• In 93% of 100 clinics dual HIV/HBV infection rate 310%
• Cases of acute HCV infection in HIV+ gay men
• Incidence of HCV infection high in HIV+ IDUs (83%)
• HIV causes HBV and HCV to progress more quickly
• People with co-infection have higher risk of liver
disease from ART but benefits of HIV treatment seem
to outweigh risks from additional liver-related sideeffects

What does the liver do?
•
•
•
•
•
Stores energy
Produces bile
Stores vitamins and minerals, including iron
Destroys and deals with poisons and drugs
Produces chemicals for most of the chemical
reactions in the body
• Repair damage and renew itself

Hepatitis B
• Routes of transmission
• Chronic infection – inversely proportionate to
age
• About 25% develop liver disease including
cirrhosis
• Treatment – lower levels of virus, not
everyone needs it but for many life-long
• All HBV patients screened for HIV and HDV
• Immunisation

Hepatitis B tests
•
•
•
•
•
•
08/04/2015
Hepatitis B surface antigen (HBsAg)
Hepatitis B core antibody (HBcAb)
Hepatitis B surface antibody (HBsAb)
Hepatitis B ‘e’ antigen (HBeAg)
Hepatitis B ‘e’ antibody (HBeAb)
HBV DNA

Hepatitis C
•
•
•
•
Virus mainly found in blood
Common risk factors
Liver disease usually takes many years
Many with chronic infection are
asymptomatic
• Genotypes
• Treatment – curative for many

HCV screening
• All HIV-infected pts should be screened for
HCV antibodies
• Repeat screening
– Annually
– Three monthly in MSM (minimum)
– Patients with abnormal LFTs
• Negative HCV antibody may be associated
with blunted immune response
• HCV RNA should be performed for some
individuals
08/04/2015

Case study 1
• 38yr old HIV+ gay man
• ART since 2002
• Nov 2011 abnormal LFTs – unable to do HCV
antibody
• Dec 2011 – HCV antibody neg – unable to do HCV
RNA
• Jan 2012 – HCV RNA 111
• Feb 2012 – HCV RNA 281
• March 2012 – HCV RNA 3548
• HCV genotype 1
• Previous samples – HCV RNA neg Aug 2011; pos
Nov 2011
• Acute or chronic infection – what treatment
approach?

Case study 2
•
•
•
•
•
•
•
•
Local outbreak of HIV among IDUs
29 yr old male former IDU
Known HCV genotype 3a
Previously attended RHH but lost to follow-up
2008 HIV neg
2010 Re-engaged after seen in outreach
Found to be HIV positive
Had HCV treatment for 48 weeks and EOT
response – awaiting SVR

Case study 2 - Treatment
• Cannot be sure if acute or chronic infection
• Discussed merits of treatment now or later
using triple therapy
• Consider change of ART regime – lessen
anaemia and reduce liver toxicity
• Going on holiday and wishes to defer HCV
treatment
• In meantime stabilise on new ART regime
