Brief summary
this study consists of the study of markers of skin, muscular, neurocognitive and bone aging in HIV infected adults and to compare the frequency of these signs to the general population of same gender and age.
Detailed description
Nowadays, the elevated frequency of cancers as well as cardiovascular, neurocognitive and bone diseases seems to denote a process of accelerated aging in the treated HIV-infected population of western countries, who are 40 to 50 years old in median. Markers of age-related alterations should be compared to the distribution among the general population whenever possible, to disentangle the effect of HIV and "normal" ageing or ageing due to other conditions. Common mechanisms should be better understood, more specifically those related to the impact of tobacco, antiretroviral treatments, and nutritional components. For markers of skin, muscle, neurocognitive function and bone ageing, the distribution of the general population is available and, in addition, alteration of these markers might have common mechanisms, such as insufficiency in 25 hydroxy vitamin D or nutritional parameters. Therefore, a joint study of these three organs seems particularly relevant. This aim is to study markers of skin, muscular, neurocognitive and bone aging in HIV infected adults and to compare the frequency of these signs to the general population of same gender and age.
Interventions
PROCEDUREDXA (dual-energy x-ray absorptiometric) measurement
DXA, evaluation of muscular function and muscle strength; neurocognitive tests; non invasive analysis of mechanical skin properties; food frequency questionnaire; laboratory assessment (25 hydroxy vitamin D, calcium/phosphate metabolism, bone remodelling markers, T cell activation).
