HPA ,500 living with HIV (1.4/1000) 86,500 living with HIV (1.4/1000) 25% unaware 25% unaware 6,630 new cases – 54% heterosexual, 42% MSM Heterosexual cases - 63% Black Africans - 68% acquired abroad 6,630 new cases – 54% heterosexual, 42% MSM Heterosexual cases - 63% Black Africans - 68% acquired abroad
HIV and AIDS New Diagnoses and Deaths
*Sub-Saharan Africa represented the presumed geographical area of exposure for 422/551 cumulative number of heterosexually infected women in Scotland infected outwith Scotland

HIV positive children / adolescents in the UK Cumulative To date 1700 (<16y of age) 95% vertically infected 50% born abroad Currently 1000 in paediatric follow-up 80 newly diagnosed in % born abroad
HIV & pregnancy HIV & pregnancy …but don’t forget the non vertically acquired infection….
HIV & Pregnancy - UK Overall 2.2 /1000 pregnant women infected - London England Scotland 0.9 UK born women 0.46 Overall 2.2 /1000 pregnant women infected - London England Scotland 0.9 UK born women ,429 children born to HIV infected women in the UK (8%) infected 11,429 children born to HIV infected women in the UK (8%) infected 74 children diagnosed in UK in % born abroad 74 children diagnosed in UK in % born abroad
Universal antenatal screening – late 2002 in Scotland (Health Protection Scotland) Current Glasgow antenatal screening rate: 95% (HPS)
Interventions to Reduce Perinatal Transmission of HIV Intervention Tx rate None % Avoid Breast feeding % AZT mono Rx (076) 6 - 8% Pre labour CS + / - ART 2% Pre labour CS + AZT mono <2% Combo Rx (VL < 50) remains ~ 1% (Courtesy of Hermione Lyall)
? numbers of UK born children HIV infected children 772,000 infants born in the UK in ,230 had mothers with diagnosed HIV. -1% likely to be infected. - large majority diagnosed within a year 70–120 undiagnosed women probably gave birth. - 30% of their infants are likely to be infected - 40% of infected infants diagnosed within a year. - HIV-positive children can survive into their teens before developing symptoms - Two-thirds of HIV-positive infants in the UK are born to HIV- positive women who remain undiagnosed throughout pregnancy
HAART & prognosis in children Gibb, BMJ 2003
Infants : Direct effects on CNS Immature brain – presents as static/progressive encephalopathy Prevalence of HIV related CNS disease pre HAART 20-50% - classic triad of developmental delay (motor & speech), microcephaly, & motor deficit (spastic quadriplegia/diplegia or hypotonia) - more advanced disease – higher rates but CNS involvement in under 1’s can occur before significant immunosuppression - may be presenting feature of HIV (18% of AIDS presentations) -highest incident rate in first 2 years of life
Audit of perinatal HIV transmissions in England ( ) 3400 infants born to HIV infected mothers - 87 infected children - no transmissions from optimally managed mothers with UVL at delivery 30% - mothers diagnosed at/before delivery - 2 deaths and 20% c AIDS defining illness 70% - mothers undiagnosed (15% seroconversion) - 9 deaths and 60% c AIDS defining illness
Testing – the epidemiological indications infants and children whatever their age where the mother has HIV, or may have died of an HIV-associated condition infants born to mothers known to have HIV in pregnancy infants born to mothers who have refused an HIV test in pregnancy infants and children who are presented for fostering/adoption where there is any risk of blood-borne infections infants and children newly arrived in the UK from high- prevalence areas (they may be unaccompanied minors) infants and children with signs and symptoms consistent with an HIV diagnosis infants and children being screened for a congenital immunodeficiency
… a negative antenatal HIV test does not rule out a diagnosis of paediatric HIV………..
‘Don’t forget the children’ Consensus CHIVA, BHIVA and BASHH statement 2009 MISSION STATEMENT The HIV status of all the children of known HIV-positive adults in the UK should be known as a matter of clinical urgency
Recommendations for standards of care (2009) All adult HIV services, including statutory and voluntary, as well as NHS and social services, must have protocols and procedures in place to ensure that all children of HIV- positive parents are tested for HIV. All HIV units will need to perform a ‘look back’ exercise to establish the HIV status of any children whose HIV-positive parents attend that service. All new HIV-positive patients attending adult HIV services should have any children identified, tested and the information clearly documented. There need to be joint protocols in place between health and social care to manage those cases where parents initially refuse, in order that these cases may be dealt with sensitively and appropriately. A clear pathway of referral needs to be identified within the multidisciplinary team. All healthcare professionals have a duty to ensure the safety of children, so if the child is persistently being put at risk by not being tested then there is a clear threshold for referral to child safeguarding services.
Rosie The clinical indications for testing ……….
BHIVA 2008 – when to test Who to consider for HIV testing infants and children whatever their age where the mother has HIV, or may have died of an HIV-associated condition infants born to mothers known to have HIV in pregnancy infants born to mothers who have refused an HIV test in pregnancy infants and children who are presented for fostering/adoption where there is any risk of blood-borne infections infants and children newly arrived in the UK from high-prevalence areas (they may be unaccompanied minors) infants and children with signs and symptoms consistent with an HIV diagnosis infants and children being screened for a congenital immunodeficiency
How to test
Scenario: OPD Letter from adult services ‘Please see this well 14 y old whose mother presented with PCP 9 months ago and was diagnosed with HIV. Mother & son in UK for 1 year (asylum seekers). Mum very reluctant to have son tested and took a lot of persuasion to agree to referral……’
Question Why is mum reluctant to test??
Mother: reasons not to treat! Disclosure of her own diagnosis Fear of effect of positive result Son ‘well’
Question Is he well? Is the teenager competent to consent to testing? What stress is this teenager under i.e. can he handle a positive result?
Gillick competency/Fraser guidelines ‘parental right to determine whether their…child below the age of 16 will have medical treatment terminates if and when the child achieves a sufficient understanding and intelligence to enable him or her to understand fully what is proposed’ Lord Scarman – House of Lords judement Gillick v West Norfolk and Wisbech Area Health Authority (1985) Is child competent to make own decisions & understand the implications of those decisions?
Adolescent stressors! Teenage life! New migrant! Language Cultural Educational Migration related Addition of a HIV diagnosis!!!!!!!!!!!!!!!
Question If mum refuses to consent to test what does the ‘law’ say?
Parental rights ( Domestic law and European Convention) Medical confidentiality Right to life i.e. state should protect life Right to respect for private life and personal privacy To make their own decisions regarding their children’s medical treatment To enjoy intimate family life with a child To enjoy a child’s company
Adolescent / child’s rights Medical confidentiality Right to life i.e. state should protect life Right to respect for private life and personal privacy Children’s Act 1989 ‘best interests of the child’ ‘wherever possible children should be brought up and cared for within their own families’
Legal / ethical issues The welfare and safety of the child are paramount. Both parent and child have rights protected by UK law: e.g. confidentiality of medical information and the right to life. If an older child is deemed competent to consent on their own behalf to a test, they must be fully and appropriately informed of all relevant information prior to giving their consent. ‘work with the parents’ to negotiate the testing of children and find mutually acceptable ways forward, preserving the family unit wherever possible.
