Study Description
Brief 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 we monitor individuals with HIV infection. The results may also assist in the design of future studies for the treatment of diseases associated with ageing.


Condition or disease
HIV Positive Ageing

Detailed Description:

Multicentre, prospective, observational study over 3 years.

Our study will describe the impact of advancing age on the experience of living with HIV in England and Ireland. To address this we will establish cohorts of HIV-positive people aged >50 and <50 years as well as demographically matched HIV-negative people aged >50 years.

  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.

Groups and Cohorts

Group/Cohort
HIV positive over 50 years of age

All study subjects will undergo a whole body DEXA scan (dual energy X-ray absorptiometry). at the beginning and end of the study.

Blood sample collections for the determination of the plasma concentrations of tenofovir and the third agent (i.e. a non-nucleoside reverse transcriptase, protease, entry or integrase inhibitor) in the patient's regimen will be drawn

HIV positive under the age of 50

All study subjects will undergo a whole body DEXA scan (dual energy X-ray absorptiometry). at the beginning and end of the study.

Blood sample collections for the determination of the plasma concentrations of tenofovir and the third agent (i.e. a non-nucleoside reverse transcriptase, protease, entry or integrase inhibitor) in the patient's regimen will be drawn

HIV negative over the age of 50
All study subjects will undergo a whole body DEXA scan (dual energy X-ray absorptiometry). at the beginning and end of the study.


Outcome Measures

Primary Outcome Measures :
  1. clinical manifestations of ageing [ Time Frame: after 2 years ]
    To analyse the incidence and outcomes of co-morbidities in older-HIV-positive people and their relationship with demographic/clinical factors.Comparison of three groups HIV+ve >50, HIV+<50 and HIV-ve >50. White or black african - analysis of demographic details and co-morbidity details collected at each visit.


Secondary Outcome Measures :
  1. variations of anti-retroviral medication associated with age. [ Time Frame: after 2 years ]
    Comparison of two groups HIV+ve >50 and HIV+ <50 measurement of blood concentrations of HIV medications

  2. to assess the potential impact of age on drug efficacy, drug-drug interactions and co-morbidities. [ Time Frame: two years ]
    Comparison of three groups HIV+ve >50, HIV+<50 and HIV-ve >50. Drug related side effects collected at each visit and also Co-morbidity details collected at each visit.


Other Outcome Measures:
  1. To contribute to the development and implementation of evidence-based recommendations for the clinical monitoring of older HIV-positive patients. [ Time Frame: after 2 years ]
    Comparison of co-morbidities in relation to age in the three groups: HIV+ve >50, HIV+ve <50 and HIV -ve >50.


Biospecimen Retention:   Samples With DNA
Blood for storage Blood (serum and plasma,) and urine samples will be collected at visits 1 and 3 stored for subsequent projects of the potential pathogenic mechanisms underlying age-related diseases. This will include assessment of vitamin-D and PTH and probably DNA analysis.
