A Practical Guide to HIVonWorld AIDS Day Ria Daly ST3 GU/HIV Medicine
UK • Public knowledge of HIV in the UK is declining • Lack of understanding about HIV and it’s relevance in the UK • For people to respect and protect themselves and others, they need to understand the facts and reality of HIV in the UK. • International • “Universal Access and Human Rights” • Universal access to information, prevention and testing for people at risk of infection.
What should you know about HIV? • HIV – Current UK facts and figures • HAART – Overview of HAART and it’s impact • HIV testing • What the guidelines say • Who should be tested? • How do I test? • Where to turn when the result is positive • The Law and HIV

HPAHIV in the United Kingdom: 2009 Report 83,000 infected at the end of 2008 27% of people with HIV in the UK are unaware of their infection
Prevalence of previously undiagnosed HIV infection, UK: 2007 Unlinked anonymous prevalence monitoring
HPAHIV in the United Kingdom: 2009 Report 7,298 new diagnoses New diagnoses among MSM remained high in 2008
HPAHIV in the United Kingdom: 2009 Report • Four out of every five MSM probably acquired infection in the UK. • Heterosexually acquisition in the UK • 740 in 2004 → 1,130 in 2008. • Preliminary data for the first six months of 2009 1 in 5 MSM &1 in 10 heterosexuals newly diagnosed with HIV were likely to have acquired their infection within the last six months.
Why is early diagnosis important? • Late diagnosis • Increased morbidity and mortality • Impaired response to HAART • Increased cost to health services • 55% patients were diagnosed with a CD4 <350 at diagnosis in 2008, the threshold at which treatment is recommended to begin • 73% patients who died from HIV in 2008 had presented late • Many late presenters have been recently seen by health care professionals

Early Diagnosis to Prevent Transmission • Knowledge of HIV status is assoc with reduced risk behaviour • Estimated HIV related lifetime cost per diagnosed individual £280,000 to £360,000 • Modelling has suggested that in the US 50% of new infections occur from undiagnosed individuals • Preventing 3,550 HIV infections probably acquired in the UK, and subsequently diagnosed in 2008, would have saved over £1.1 billion in future HIV-related costs

HAART • Highly Active Antiretroviral Therapy • 1996 • Suppress Viral Load & Increase CD4 counts • Combination therapy • More effective, better tolerated, simplified dosing • Decreased mortality

Antiretroviral Therapy Cohort Collaboration Lancet 2008 • Life expectancy in high income countries • >43,000 treatment naïve patients initiated on cART • Decreased to 59.8% if CD4 <100cells/ul • Decreased to 66.4% if IVDU
HAART • Must be taken on time!

BASHH, BHIVA & BISGuidelines for HIV Testing 2008 Aims • Facilitate increase in HIV testing in ALL health care settings • Reduce the proportion of undiagnosed HIV • Benefit individual and public health • Encourage ‘normalisation’ of testing • Recognise the need for a newly diagnosed individual to be immediately linked to HIV treatment and care • Maintain confidentiality within any health care setting
Opportunistic screening 2 per 1,000 population recommended to expand HIV testing in the local population 43 English Local Authorities in 2008 Testing patients with ‘clinical indicator diseases’
Who should be tested? Opt Out’ for: • All patients attending GUM or sexual health clinics • All women attending antenatal services • All women attending termination of pregnancy services • All patients registering with drug dependency programmes reporting a history of injecting drug use • All patients diagnosed with Tuberculosis, Hepatitis B, Hepatitis C and Lymphoma
Any other patients presenting for healthcare where HIV enters the differential diagnosis including primary HIV infection • All individuals known to be from a high prevalence country • MSM • All men and women who report sexual contact with individuals from areas of high HIV prevalence, abroad or in the UK.
