Neurocognitive function in perinatally HIV- infected young people and HIV-negative siblings in England Kate Sturgeon, Ali Judd, Aimie Nunn, Diane Melvin, Caroline Foster, Alan Winston, Marthe Le Prevost, Di Gibb, Alejandro Arenas-Pinto On behalf of the Adolescents and Adults Living with Perinatal HIV (AALPHI) Steering Committee

Background Perinatally HIV-infected children perform less well than controls on general cognitive tests, processing speed and visual/spatial tasks Few neurocognitive studies in young people –most are in younger children as part of trials –many do not have appropriate control groups –most are not longitudinal and so cannot assess change Unclear of effect of background/ upbringing compared to HIV and ART exposure

AALPHI Aims 5 key domains: Neurocognitive Cardiac Metabolic Sexual and reproductive health Anthropometry and bone composition

AALPHI Inclusion criteria HIV-infected cases (PHIV+) n= years Able to give informed consent/assent Living in the UK for over 6 months Willing to give a blood sample Able to speak and understand English Willing to be followed up annually for duration of the study HIV negative controls (PHIV-) n= years Able to give informed consent/assent Awareness of HIV in the family Living in the same household as case or have an HIV positive parent, sibling, friend or partner Living in the UK for over six months Able to speak and understand English Willing to have an HIV test Willing to be followed up annually for duration of the study

Methods Participants: –295 PHIV+ aged yrs, all had UK paediatric care –90 HIV- aged yrs, half are siblings of PHIV+ Baseline: 12 tests across 6 neurocognitive domains –Executive function –Speed of info. processing –Attention/ working memory –Speed of Learning –Visual Memory –Fine motor skills

Neurocognitive Tests Interview 1 DomainNeurocognitive Test Executive functionCogstate groton maze Color Trails 2 Speed of information processingCogstate detection task Color Trails 1 Attention/working memory Cogstate Identification WAIS-IV coding Speed of learningCogstate One Card Learning International Shopping List Visual memoryCogstate International shopping list delayed One back test Fine motor skillsGrooved pegboard

Analysis z-scores calculated using normative manufacturer data for each test and averaged per cognitive domain –z-score > 0 = above average function compared to norms –z-score < 0 = below average function compared to norms NPZ-6 = mean z-score across all 6 domains Predictors of NPZ-6 using linear regression –A priori: age, sex, ethnic, born outside UK, AIDS (CDC-C) –Psychosocial: death of parents, fostered/adopted, current education/employ, who living with, whether parent in work –Alcohol, smoking and drugs, anxiety/depression (HADS) –PHIV+ only: year 1 st presented, nadir & current CD4, cumulative yrs VL<400c/ml, age starting ART, current ART status, current EFV use

Discussion PHIV+ & HIV- scored worse than population norms –CogState norms are largely Australian caucasian males PHIV+ CDC C had the poorest performance –many presented with AIDS and started ART after PHIV+ with no CDC C scored similarly to HIV- overall Other differences were due to non-HIV factors: –Most black African participants were born in Africa before cART was available and from many different countries; varying age at entry to UK & degree of cultural adjustment –Death of both parents, and depression, also associated with poorer scores Impact on day-to-day life needs further investigation

Anxiety and depression in AALPHI Measured using the Hospital Anxiety and Depression Scale (HADS) In a multivariable model adjusted for UK norms (YP aged 25-29)*: –No difference in scores between PHIV+ and HIV- or UK norms *Breeman - QualLifeRes 2015;24:39108 ) AnxietyDepression Increased anxiety (lower z scores) : -Death of both parents -Reported ever thinking life not worth living Increased depression: -Death of one or both parents Lower anxiety (higher z score): -Higher self-esteem (Rosenburg) -Higher quality of life (PedsQL) Lower depression: -Female sex -Higher self-esteem -Higher quality of life
