Brief Summary:
The purpose of this project is to determine the incidence of osteoporosis in the investigators' population of HIV-infected patients and to assess the efficacy and security of zoledronic acid, whose efficacy in post-menopausal women with high fracture risk treatment and in Paget's disease treatment has already been demonstrated.

Condition or disease Intervention/treatment Phase
HIV Infections Drug: Zoledronic acid Behavioral: Lifestyle modifications Phase 4

Detailed Description:

The lower bone mineral density that has been described in patients with HIV-infection has not meant an increase of long term complications. Nevertheless, it could involve an increase if the associated co-morbidity in the future, taking in care that in general population osteoporosis increases 4 times the pathologic fracture risk. That is why it is necessary to know the real prevalence of osteoporosis in this population of patients so the real dimensions of the problems can be defined.

This project wills to determine the incidence of osteoporosis in our population of HIV-infected patients and to assess the efficacy and security of zoledronic acid. If the annual use of endovenous zoledronic acid obtains equivalent results to those obtained with oral and weekly alendronate in other studies with the same population, its use would be justified because of its posology benefits. The annual administration can improve compliance in patients who are receiving a big quantity of drugs, as HIV-infected patients do, and who probably have to be treated for life. Moreover, its elimination is renal so there is absence of interactions with antiretroviral drugs what makes of zoledronic acid a very promising alternative. Finally, there is no risk of digestive intolerance because of its parenteral administration and it has a better posology than oral bisphosphonates.
