Adolescents in CHIPS - Linking to CHIC: Young Persons (YP) Leaving CHIPS are Lost to Follow-Up - What to Do Next?

1. Adolescents in CHIPS - linking to CHIC Young Persons (YP) leaving CHIPS are lost to follow up - What to do next? Katja Doerholton behalf of CHIPS NSHPC HYPNET CHIC

2. Introduction to CHIPS & NSHPC • Surveillance of obstetric and paediatric HIV in the UK and Ireland through the National Study of HIV in Pregnancy and Childhood (NSHPC) • CHIPS is a multicentre cohort study of HIV infected children under care in 56 hospitals in the UK & Ireland • 85% children currently reported to the NSHPC are also in CHIPS follow up • Prospective data collected annually • Clinical progression, VL, CD4, growth, LDS, ART, side effects

3. Introduction to the UK Collaborative HIV Cohort Study (UK CHIC) • Collaboration of HIV clinics in the UK • Most London centres, excluding St. Thomas, St. George‘s & Newham • Outside London centres are Brighton & Edinburgh • Aims • To monitor changes in deaths and AIDS over time • Uptake & response to HAART • Laboratory toxicity data

4. Leaving Paediatric CareCHIPS Age group by year of follow up

5. 3% Scotland 0% N. Ireland 19% Rest of England 9% Ireland <1% Wales 69% London Distribution of ≥14 years of age in CHIPS Total n= 258

6. Leaving Paediatric Care • 1,043 children/YP in current CHIPS follow up • 50% of the cohort ≥10 years • 258 (25%) are ≥ 14 years • 114 have already been transferred to adult care since the start of CHIPS • 55 (48%) stayed at the same adult centre

7. Linking CHIPS CHIC • 114 YP transfered from CHIPS to adult care of which only 40% in current CHIC follows up • BUT! around 60% of YP are not matched and lost to follow up • CHIC data are more limited • no growth, no clinical LDS or clinical adverse event data available • Additional problem • Mobile population, YP move around the country as they grow up, i.e. travelling abroad, going to university/college

8. Teenagers with late presentation of vertically-acquired HIV infection in UK Rashida Ferrand, Katia Prime, Caroline Foster, Eva Jungman • CHIPS/NSHPC and HPA data • Describe 38 YP diagnosed ≥13 years • 30% developed AIDS • 60% required ART shortly after diagnosis • Delay in diagnosis • What impact has this on clinical outcome • STI and ongoing transmission NEED for AWARENESS of LATE PRESENTATION

9. YP cohortsUp and running projects • Swiss and Dutch YP are followed in the same adult database • BUT small numbers in both countries • US are developing a cohort of vertically infected YP • Very detailed studies on growth, drug related adverse events, aim of enroling 600 HIV+ YP • Mulago Hospital, Uganda • Follow up of YP with an already existing adolescent cohort

10. First „brainstorming“ between CHIPS/NSHPC CHIC HYPNET July 07 Conclusions from the first meeting • To continue follow up of this unique cohort with available clinical and treatment history • Need for rapid action and development of a YP cohort • CHIPS should take the lead

11. Aims of the YP cohort • Evaluate effects of perinatally acquired HIV in YP • Including growth, sexual maturation • Response and use of combination ART • Describe long term complications of HIV and ART including drug toxicity • Hyperlipidaemia and Lypodystrophy, Hyperglycaemia • Cardiovascular events/changes, Hypertension • Effects on bone metabolism (biochemistry, and other locally available data)

12. Aims of the YP cohort • Early talks about collaborations with other similar cohort studies • Africa, Europe and the US • Further collaborations with other non HIV cohort studies to help identify effect of HIV/ART

13. Next Step 2nd CHIPS/NSHPC CHIC HYPNET meeting • To discuss aims and data collection in more detail • Funding, application for grants etc. • Suggestions, ideas welcome!!!
