Summary

The purpose of this study is to identify medical conditions that may cause particular problems to individuals receiving care for HIV infection over the age of 50. In addition, as the effects and potentially the side effects, of HIV medication may change with age, this study will also investigate the association between age and differing effects of antiretroviral therapies such as treatment outcomes, side effects and the levels of drugs in blood. Results from this study may inform future HIV treatment guidelines on how individuals with HIV infection are monitored. The results may also assist in the design of future studies for the treatment of diseases associated with ageing.

Detailed description

Multicentre, prospective, observational study over 3 years. The study will describe the impact of advancing age on the experience of living with HIV in England and Ireland. To address this cohorts of HIV-positive people aged \>50 and \<50 years (as well as demographically matched HIV-negative people aged \>50 years) will be established. 1. To analyse the incidence and outcomes of co-morbidities in older-HIV-positive people and their relationship with demographic/clinical factors. 2. To evaluate associations between antiretroviral drug concentrations and age, and to assess the potential impact of age on drug efficacy, drug-drug interactions and co-morbidities. 3. To contribute to the development and implementation of evidence-based recommendations for the clinical monitoring of older HIV-positive patients. 2000 will be recruited in all either white or black african individuals (self reported) 1000 will be Over 50 years of age and HIV positive, 500 will be under the age of 50 and will be HIV positive and 500 will be over the age of 50 and be HIV negative.
