HIV+ patients are considered at risk for excessive bone fragility. Several factors could contribute: age, male sex, low body mass index (BMI), HIV infection per se, vitamin D deficiency, using tenofovir/a protease inhibitor (time on and/or current use). Tenofovir is used in a backbone of nucleosides/nucleotides analogues with emtricitabine (FTC), licensed as TRUVADA�, or without this analogue, licensed as VIREAD�. FTC closely resembles lamivudine (3TC) but is 5-fluorinated, the daily intake of fluoride is ~15 mg. Fluoride induces bone formation by stimulating osteoblasts, of often impaired bone quality. The aim of the study is to compare in a cross-sectional design fluoride levels, bone renewal, bone mineral density (BMD) in HIV+ male patients treated by TRUVADA� or VIREAD� for more than 60 months. The patients will be randomly selected, then matched according to age, ethnic origin, BMI.
