What is the latest information and/or studies on bone loss in long term survivors w/HIV (14 years)? My partner is experiencing extreme pain related to bone loss, as are others we know. All are on Viread. Is there any proven correlation between Viread and bone loss in humans?
Response from Dr. Henry
Bone loss in general seems to be accelerated in HIV+ patients but the reason why is not well worked out. Early studies suggested that the protease inhibitors may be involved but the story has gotten more complicated. There are high levels of bone loss in the general population due to diet and exercise issues that confound the picture further. There is concern about tenofovir impacting bone health but the number of cases of documented problems are still small. Other drugs that can cause mitichonfrial damage (such as NRTIs) have in some studies been linked to slight elevations in lactic acid associated with bone loss. DEXA scans are used to evaluate bone density. I have many patients on OsCal D or equivalent to promote/protect bone health. Most patients with mild/moderate bone loss do not experience severe pain so I would be concerned about other possibilities (such as aseptic necrosis of the hip). A good discussion with the HIV specialist caring for your partner would likely lead to further evaluation and search for a way to control the pain. KH
