Primary Outcome Measures:

Evaluation of maraviroc's effect to bone metabolism and bone mineral density [ Time Frame: 78 weeks ]
Follow up HIV infected patients who take maraviroc for their bone mineral density by DEXA and for following blood/urine markers of bone metabolism and chemokine for 72 weeks:
- Bone and chemokine markers (DPD, NTX, CTX, TRACP, BAP, osteocalcin, MIP-1alpha, MIP-1beta and RANTES)
- Dual-energy X-ray absorptiometry

Secondary Outcome Measures:

Duration of the treatment efficacy [ Time Frame: 72 weeks ]
Evaluate overall HIV management status over time with:
- Other infections: HBV, HCV, RPR, TPHA
- HIV treatment markers: CD4, CD8, CD4/CD8, HIV-RNA
- HAART regimens and start dates
- Other medications: antibiotics, anticoagulants, antiplatelets, NSAID, steroids
- Past medical history
- HIV risk behaviors, age, sex

Biospecimen Retention: Samples Without DNA

Blood serum, blood plasma, urine
