    ObjectiveTo evaluate the influence of highly active antiretroviral therapy (HAART)on bone mineral density(BMD) of human immunodeficiency virus (HIV) infected patients and correlating clinical factors.MethodsThe clinical data from 2007 to 2008 were analyzed, including 50 patients treated with HAART (named treated group), 12 HIV-infected antiretroviral-naive patients (named untreated group) and 20 healthy people (named control group). Lumbar, femoral neck, femur, femoral greater trochanter and whole body BMD were measured by dual energy X-ray absorptiometry. The data were respectively analyzed.ResultsThere were 19(38.0%) patients with osteopenia and 1 (2.0%) patient with osteoporosis in the treated group. There were 6 (50.0%) patients with osteopenia and 2 (16.7%) patient with osteoporosis in the untreated group. There were 5 (25.0%) patients with osteopenia, no one with osteoporosis in the control group. The prevalence of osteopenia/osteoporosis was statistically higher in the untreated group than that in the control group (P=0.02). The BMD of femur, femoral neck and greater trochanter [(0.97±0.14), (0.91±0.13), (0.76±0.12) g/cm2] in the HIV-infected group (including the treated and untreated group) were significantly lower than that in the control group [(1.04±0.12), (0.98±0.14), (0.84 ± 0.11) g/cm2, P<0.05]. There were no significantly differences in the BMD between the untreated group and the treated group. In the treated group, osteopenia/osteoporosis correlated with body weight less than 60 kg (r=0.074, P=0.004) and the viral load before HAART (r=5.103, P=0.021).ConclusionsThe prevalence of osteopenia and osteoporosis in antiretroviral-naive HIV-infected patients is higher. The BMD of HIV-infected patients are reduced compared with the healthy people. The BMD is similar among HIV-infected patients irrespective of antiretroviral treatment. Body weight less than 60 kg and the viral load before HAART are the risk factors of osteopenia/osteoporosis for the HIV-infected antiretroviral patients.
