History of Changes


Osteopenia and osteoporosis are being described more frequently in people with HIV infection. This study will test the efficacy of alendronate in comparison with a placebo after 2 years, in people with primary osteoporosis. People will receive the recommended adequate intake of calcium and vitamin D.

Primary Outcome Measures

  • Percentage of variation of lumbar BMD on DEXA scan at month 24 versus month 0 for patients included with lumbar osteoporosis (femoral for those included with only femoral osteoporosis)
Secondary Outcome Measures:
  • Percentage of variation of femoral T-score between M0 and M24
  • Percentages of variation of lumbar and femoral T score between M0 and M12
  • Evolution of bone metabolism markers
  • Occurrence of fractures
  • Tolerance of alendronate
  • Measure of the prevalence of osteopenia and osteoporosis in HIV-infected men and women
  • Description of the evolution of osteoporosis in HIV-infected men and women receiving calcium and vitamin D to define risk factors for osteoporosis in HIV-infected persons

Enrollment: 140
Study Start Date: October 2004
Study Completion Date: November 2008
Primary Completion Date: November 2008 (Final data collection date for primary outcome measure)

Detailed Description:

The purposes of this trial are:

  • To study the efficacy of alendronate in HIV-associated osteoporosis
  • To measure the prevalence of osteoporosis in HIV patients and to detect risk factors in
a large cohort of HIV patients from the screening phase



Ages Eligible for Study: 18 Years and older  
Sexes Eligible for Study: All  
Accepts Healthy Volunteers: No  


Inclusion Criteria:

  • Non-pregnant
  • Non menopausal women
  • Total femur BMD below -2.5 SD (T score) or lumbar spine BMD below -2.5 SD (T score) or BMD below -1 associated with a vertebral osteoporotic fracture (diminution of vertebral height over 20%)
  • HIV infection known for at least 5 years
  • CD4 cell count over 50/mm3
  • Karnofsky score over or equal to 70
  • Written informed consent.

Exclusion Criteria:
  • Osteoporosis resulting from a cause other than HIV: vitamin D deficiency (in that case, after receiving high-dose calcium and vitamin D for 1 month, patients will be randomized without a new screening), renal failure, heart failure (NHYA class III or IV), treatment with glucocorticoid at a dose over or equal to 0.5mg/kg/d for 15 days or more at time of inclusion or during the previous 6 months; thyroid or other endocrine disease if untreated for more than 6 months; hypercalciuria

  • History of treatment for osteoporosis
  • History of malignancy in the previous 5 years (except skin cancer and Kaposi)
  • Cytotoxic chemotherapy or cytokine therapy
  • Liver cirrhosis
  • Breast feeding
