  • Of the estimated 6,840 (95% confidence intervals 6,600-7,050) persons newly diagnosed with HIV in the UK in 2007, an estimated 56% (3,860 [3,700-4,000]) acquired their infection heterosexually and an estimated 38% (2,630 [2,500-2,750]) were men who have sex with men (MSM). In recent years there has been a decline of new HIV diagnoses in HIV-infected heterosexuals from sub-Saharan Africa who were probably infected in their country of origin. In contrast, there was no evidence of a fall in the current high rate of HIV transmission among MSM within the United Kingdom, which has remained at epidemic level.
  • Among MSM newly diagnosed in 2006, 83% probably acquired their infection in the UK. Among white MSM this percentage was 84% compared to 74% among MSM of all other ethnic groups. There is evidence that MSM born abroad are also at risk of acquiring HIV infection within the UK. Among heterosexuals, 17% probably acquired their infection in the UK. A greater percentage of heterosexuals of white ethnicity probably acquired their infection in the UK (50%) compared to those of black African ethnicity (8%) and those among other ethnic groups (30%). Migration is a major cause of late diagnosed and reduce access to testing and treatment in many countries, including the UK Following earlier steep increases in UK, there is a levelling off in diagnoses among black-African individuals largely due to changes in immigration Small but important increases in number of heterosexually acquired infections acquired in the UK, particularly among black-African individuals HIV prevalence in UK amongst black-African populations greatly exceeds that amongst other ethnicity groups.
  • There have been 2 major NHS reorganisations since the Sexual Strategy in England Shifting the Balance of Power (abolition of health authorities) And Changes in commissioning to Patient-led NHS (2006) Our health, our care, our say (2006) – deliver of care in partnership Changes in commissioning (2006) offer the opportunity to have more specialist care support for commissioning but consequent changes in personnel and population configuration may present challenges to local service development Practice based commissioning should facilitate patient pathways and closer working between acute and community based services. Our health, our care, our say (2006) – provides an opportunity for innovative methods for providing services to tackle hepatitis and HIV
  • Since the National Strategy for Sexual Health (England) in 2001, we have seen increase testing of HIV offered to all GUM attendees as part of STI screen, o ver 700 000 screens in 2007 with a High uptake >80% Additionally there is since 1999 routine HIV testing in the antenatal setting with >85% uptake TB clinics- routine in most clinics across London Up to 20% co-infection rates among BA TB patients
  • There were 35,242 individuals reported to SOPHID in 2004 with both a CD4 count and level of ARV reported (88% of a total 40,000 reported). 14% of these – almost 5,000 – had CD4 counts less than 200 *Click* Of those 5,000 individuals, 19% - almost 1000 (950) – were not receiving ARV.

      • Syphilis
      • LGV
      • HCV (new)
    • 2. Data linking exercises

  • In-depth Analyses Enhanced Syphilis Surveillance among MSM
    • HIV positivity associated with
      • Being non white
      • Born outside UK
      • Presenting later
      • Greater number of sexual contacts
      • Diagnosed in London
      • Meeting sexual contacts in Sauna and on the Internet
      • Being older – peak in 40-44 and 45-49
  • SNAHC pilot S urveillance of N ewly A cquired hepatitis C in MSM
    • Objectives
    • To assess the burden of disease, behavioural and other risk factors
    • To develop information systems for public health actions
    Crude HCV incidence in HIV+ MSM, London and Brighton , 2002- June 2006 Surveillance Case definition Definite Case: Documented anti-HCV sero-conversion HCV antibody positive and has a documented negative HCV antibody within the previous 36 months. Probable Case HCV RNA positive AND HCV antibody negative or equivocal

  • Linking Exercises TB HCV Pneumococcal
  • TB co-infections
  • Incidence of Invasive Pneumococcal Disease in HIV-diagnosed individuals England and Wales: 1996-2005 Source SOPHID & EPS incidence estimate of 141/100,000, 10 times higher than background adult population
  • Changes since 2001
    • Major NHS reorganisations since Strategy
      • Shifting the Balance of Power (abolition of health authorities)
      • Changes in commissioning to Patient-led NHS (2006)
      • Our health, our care, our say (2006) – deliver of care in partnership
    • Changes in the Epidemiology of HIV, TB, HCV
      • Increased STI among MSM, black Caribbean communities
      • Increased HIV/TB in black Africans linked to late diagnosis
  • Review of Sexual Health Strategy, MedFash for the SHIAG July 2008
    • Prioritising sexual health as a key public health issue and sustaining high level leadership at local, regional, and national level
    • Designated accountability, active performance management at PCT and SHA level
    • Delivering modern sexual health services (increasing the level and quality of services, networks and improving workforce planning and training)
    • Incorporating sexual health and long-term care for people with HIV
    • Building strategic partnerships (treatment, public health, community sector), more integrated cross- government approach
    • Commissioning for improved sexual health, including investing more in prevention, and dissemination of evidence that works
  • Improving our response to HIV co-infections
      • We need to better address needs of MSM, Black communities and IDUs
      • Improved surveillance and monitor tools
      • Better commissioning of services & prevention interventions
      • Better integrate health services to improve early diagnosis, treatment and ongoing care
        • Eg: New HIV testing guidelines (Sept 2008)
    Resources for positive HIV MSM, THT
  • Better integration of services Sexual Health & HIV Screens in GUM clinics, UK
  • Improving Surveillance
      • 1. Improve & integrate enhanced surveillance systems
        • shift from disease focus to at risk populations
        • standardising surveillance tools across system
        • better collection of behavioural information
      • 2. Develop key indicators for monitoring infection, treatment and care, and prevention efforts, for example
        • % late diagnosed
        • % not on ARV <200 ?<350
        • % of STI patients screened for HIV
        • % positive MSM tested for HCV
  • Proportion of late diagnosed in London Percentage of patients diagnosed with CD4<200 by PCT of residence >45% (4) 40-45% (6) 35-40% (8) 30-35% (6) 25-30% (6) <25% (1)
  • Proportion of HIV-infected persons not on ARV by CD4 category: UK, 2006 CD4 cell count category 31% 19% 31% Proportion not on ARV Annual survey of HIV-infected persons accessing care n = 5,144 2,407 18% 30% 31% 11,595 4,983 29,165 9,894
  • Conclusions
      • Co-infections are a significant problem among HIV infected individuals
      • We can do more to reduce co-infection in affected populations (screening and earlier testing, integrated care, targeted health promotion intervention)
      • We can improve our surveillance and develop key indicators to monitor our progress
      • We welcome the opportunity of an international collaboration to share best practice, lessons learnt and innovative approaches to reducing co-infections
