ABSTRACT
INTRODUCTION:
Bone mineral density (BMD) assessment in HIV patients is sparsely done in resource limited settings. MATERIALS ANDMETHODS:
We conducted a cross-sectional study of BMD amongst HIV patients following up in our clinic from 1 June to 1 December 2013 by performing dual-energy X-ray absorptiometry scan (Lunar Prodigy Advanced DXA System, GE Healthcare) of lumbar spine and hip. Patients on long term (≥12 months), virologically suppressive antiretroviral therapy (ART) were included. Patients who were ART naïve were included as control population. Virologic failures were excluded. Low BMD was defined by WHO T-score criteria (normal T score ≥-1;osteopenia T score between -1 and -2.5 SD; osteoporosis T score ≤-2.5 SD). Baseline risk factors associated with low BMD like age, low BMI, lipoatrophy, diabetes mellitus, current smoking, current alcohol intake, steroid exposure and menopause were recorded. ART-related factors associated with low BMD like ART duration, exposure to tenofovir and exposure to protease inhibitors (PI) were studied.RESULTS:
A total of 536 patients (66% males, 496 ART experienced and 40 ART naïve) were included in this analysis. Median age was 42 years, mean BMI 23.35 kg/m(2) and median CD4 count 146 cells/mm(3). All ART experienced patients had plasma viral load<400 copies/ml.CONCLUSIONS:
Extremely high prevalence of accelerated BMD loss amongst ART naïve and ART experienced patients in our cohort is a matter of deep concern due to its association with pathological fractures. Bone mineral loss was seen irrespective of ART used. Association of low BMD with low baseline CD4 count strengthens the case for early ART.
