Dr. Hendry, how often should a DEXA scan be performed for HIV-infected individuals on antiretroviral therapy? I had one a year ago, and am wondering if it's time for another or if it's too soon? I am 45 years old, positive for 20 years, and taking Reyataz, Norvir and Truvada.
Response from Dr. Henry
If DEXA was OK overall then no need to repeat (pace of bone loss genreally slow) for many years (exact time may be dependent on risk factors for osteoporosis). Initial assessment reasonable for persons at ristime frame k (including many HIV+ persons) but follow-up DEXA in short (1-5 years) often unnecessary particularly if standard interventions employed (vitamin D, calcium supplements and attention to other risk factors).

Does Ritonavir increase levels of norspan in body?
How Long Am I Infected?
