Introduction
• In 93% of 100 clinics dual HIV/HBV infection rate 3 10% • 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 side effects 25/04/2020 2
Cirrhosis

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 25/04/2020 4

Liver tests
• Diagnostic blood tests • Liver function tests • Ultrasound scan • Liver biopsy sometimes 5

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 25/04/2020 7
Hepatitis B - epidemiology
25/04/2020 8
Hepatitis B tests
• 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
25/04/2020 9
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 25/04/2020 10
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 25/04/2020 11
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?
25/04/2020 12
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 25/04/2020 13
When to start treatment
CD4 cells/μL >500 ≤500 HBV requiring Rx HBV not requiring Rx Start ART in some patients (2C) (Include tenofovir and emtricitabine) Defer ART Start ART (1B) (Include tenofovir and emtricitabine) Start ART (1B) (Include tenofovir and emtricitabine) HCV with immediate plan to start HCV Rx Defer ART HCV with no immediate plan to start HCV Rx Defer ART 350 –500 Start ART after HCV treatment commenced (1C) <350 Start ART before HCV treatment (1B). Discuss with HIV and viral hepatitis specialist Start ART (1C)

Response rates to HCV therapy
SVR rates
Overall
HCV Monoinfection
56-61%
HIV/HCV Co-infection
27-40% Genotype 1 42-44% 14-38% Genotype 2 and 3 25/04/2020 70-82% Up to 73% 15
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 25/04/2020 16

Summary
• All HIV + persons should be screened for HBV and HCV, and visa versa • Offer HAV/HBV immunisation to non-immune individuals • ‘Cure’ rates in HIV/HCV co-infection promising • Newer HCV drugs in development • HCV treatment response guided • Side-effects well managed with support of MDT 25/04/2020 18
