Proposed study on HIV and ageing As HIV mortality rates have dropped, an increasing proportion of individuals are living with HIV to older ages As HIV mortality rates have dropped, an increasing proportion of individuals are living with HIV to older ages Around 15% of individuals accessing HIV care in England and Wales in 2007 were aged >50 years Around 15% of individuals accessing HIV care in England and Wales in 2007 were aged >50 years There is a need to adapt the management of those living with HIV so that their clinical needs continue to be met There is a need to adapt the management of those living with HIV so that their clinical needs continue to be met However, virtually nothing is known about the likely health care needs of older HIV-positive persons However, virtually nothing is known about the likely health care needs of older HIV-positive persons
Study objective To create a nested, cohort of individuals aged >50 years, attending sites within the UK CHIC study and Dublin HIV cohort to address questions relating to several issues: - Uptake and outcomes of HAART in older individuals - ARV pharmacokinetics - Cardiovascular disease - Bone disease - CNS complications - Musculoskeletal manifestations - Women and the menopause - Sexual behaviour - Social and economic factors - CMV infection in compromising immunity during ageing - Resource utilisation
Proposed methods Nested cohort study within UK CHIC and Dublin HIV Cohort Cases: HIV-positive men and women aged >50 years from participating UK CHIC clinics/Dublin cohort
Proposed methods Nested cohort study within UK CHIC and Dublin HIV Cohort Cases: HIV-positive men and women aged >50 years from participating UK CHIC clinics/Dublin cohort Control group 1: HIV-positive men and women in three age groups (20-30, and years) attending participating clinics
Proposed methods Nested cohort study within UK CHIC and Dublin HIV Cohort Cases: HIV-positive men and women aged >50 years from participating UK CHIC clinics/Dublin cohort Control group 1: HIV-positive men and women in three age groups (20-30, and years) attending participating clinics Control group 2: Age-, sex-, ethnicity- and risk-group matched HIV-negative persons (identified from similar clinical settings)
