Adolescence & HIV – aiming for a successful transition to adult services Dr Conor DohertyRHSC Glasgow
Clinician parent child Parent Clinician Older child Clinician Adolescent Talking to adolescents Confidentiality, honesty, clarity Listen, engage, respect Non judgemental Encourage to ask questions Don’t overload, patronise and don’t assume poor understanding
Clinician - the optimal regimen - minimise s.e.’s & maximise adherence Adolescent - family dynamics - sex, drugs & alcohol - risk taking behaviour - peer group conformity What does my diagnosis mean to me? - isolation - race, ethnicity - language - migration - parental illness / bereavement - transition to ‘adult care’ - education & future plans ‘The agenda’
The transition – ‘a guided educational & therapeutic process’ • Epidemiology – identifying the clinical issues • Cases – challenges, successes, failures • Service provision and guidanceCHIVA www.chiva.org.ukCHIPS www.chipscohort.ac.ukHYPNET www.hypnet.org.uk
↑ no of adolescents ↑ age of perinatally infected cohort ↑ duration of drug exposure ↑ survival ↓ vertical transmission ↓threshold for HAART
(HYPNET/CHIVA) 2228 young people (16-24) accessing HIV care in UK (2007) - 48% heterosexual – mainly black African - 48% MSM (x2 since 1998) 654 perinatally infected> 10 y old (up to 2007) - 93% of those diagnosed with HIV <16y old are in CHIPs cohort Globally - 40% of 2.8 million new infections in 2008 in the 16-24 y old age grp(UNAIDS) HIV prevalence in 10 y in S Africa to increase from 2.1% to 3.3% by 2020(Ferrand 2009) - 38% of children requiring HAART had access to treatment in 2008(UNAIDS) Epidemiology
In clinic - the issues • Communication / education / empowerment • Medication - adherence within a teenage lifestyle - simplification of regimens - long term health & minimising complications due to HAART • Identifying the stresses • Alcohol, drugs and sex • future plans and transition of care
Newly presenting adolescentJudd et al: HIV medicine 2009 • 42 presented >13 y old (median 14 y (13-20y)) • 95% Black African and 86% born in Africa • 50% symptomatic (29% AIDS at diagnosis) & 47% as a result of screening • Median CD4 210/μl(0-689)
14 y old – newly arrived from sub-Saharan Africa Presented to adolescent services for screening Mother reluctant to screen and reluctant to disclose result Disclosure 5 months after presentation and just prior to starting HAART – relationship with mother deteriorated CD count 235 – declined treatment Regimen commenced 1 year after diagnosis Totally virally suppressed for 1 year/CD4 590 The stresses - relationship with mum & honesty around diagnosis - ? Imminent forced repatriation & all the other teenager stresses Current situation - refusal to attend clinic - taking HAART - ad hoc clinical care - refusing peer support - monosyllabic and angry ?? How to plan transition Case 1 : age 17y
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 judementGillick v West Norfolk and Wisbech Area Health Authority (1985) Is child competent to make own decisions & understand the implications of those decisions?
Case 2: 12 y old • Diagnosed aged 5/12 with PCP • Mother : 22y, single, little family support, just started HAART herself, alcohol and mental health concerns, poor clinic attendance, poor parenting skills

Teenagers and risk taking!! • >25% of teenagers are sexually active before 16y old • The younger the adolescent the less likely to use a condom • UK – highest rate of teenage pregnancy in Western Europe • 50% of all STI’s occur in the 16-24 y old • 4% of 11 year olds said they had used drugs in the last year, compared with 29% of 15 year olds in 2008 (www.ic.nhs.uk) • Drinking increases with age: 14% of 12–13s, 33% of 14–15s and 62% of 16–17s have drunk alcohol in the last week (ias.org.uk)
Treatment guidance : PENTA 2009 Clinical CDC stage B or C WHO stage 3 or 4 CD4 <350 cells / μl Virological >100,000 copies / ml Response to treatment (both naive & experienced) poorer than in young children or adults (COHERE 2008)

Long term morbidity • Neurocognitive - Children (3-7y) with CDC Class C↓ neurocognitive development (Smilth 2006) - Adolescents with CDC Class C ↑ prev of neurocognitive & psychiatric morbidity(Wood 2009) - School age children - normal IQ but ↓ executive functioning and processing speed (Koekkoek 2008)* caveat – complex aetiology of neurocognitive dysfunction and adequate control of cofounders? functional translation of neurocognitive deficits • Psychiatric↑ prev of morbidity in HIV positive adolescents (Mellins 2009)
Long term morbidity • Cardiovascular - interplay of host, viral and ART factor often not evident in adolescence. - hypercholesterolaemia, hypertriglyceridaemia & insulin resistance (Hazra 2010) - lipoatrophy/dystrophy & body image - ↑ arterial wall stiffness (carotid PWV) (Charakida 2009) - DAD/SMART studies in adults linking recent ABC to MI’s • Renal - pre HAART 10-15% of African American children had HIVAN - 22% of children had persistent laboratory renal abnm assoc with Black ethnicity, older age, tenofovir (Andiman 2009) - CHIPS cohort : Hypophosphataemia uncommon (4%), prolonged TDF use, generally reversible with TDF withdrawal (Judd 2010)
UK experience - the CHIPS data(Foster at al: AIDS patient care & STDs 2009) • 654 perinatally infected> 10 y old (up to 2007) • 79% Black African (57% born abroad) • Median age/duration UK/Eire 1 / 11y Abroad 8 / 5y • 25% AIDS defining illness • 10 deaths during adolescence Treatment – at last follow-up • 64% on ART (78% <400 copies / median CD4 554) • 18% off (previously received ART) • 18% ART naïve • 47% triple class experienced • 166 with resistance genotypes: 52 / 12 % had dual/triple class mutations • 12% severely immunocompromised (CD4 < 200) • 103 (16%) transferred to adult services at median age of 17y? toxicity data? growth/puberty/fertility/neurological/neurocognitive outcomes

Glasgow Adolescent clinic • Based at RHSC • After school • From age 11 onwards (after disclosure) • Review without parent • Review with adult consultant (GUM) • Separate consultation with sexual health advisor Encourage adolescent to take responsibility to understand & enable reasoned decisions to successfully transition to adult care
Conclusions • ‘transition’ - planned, purposeful and patient – centred - medical, psychological • Adolescents have specific service requirements & need dedicated service models • Long term morbidity of HIV/HAART • Current lack of well controlled research studies
