People with HIV Have Higher Bone Fracture Risk in Danish Study

Being HIV positive was associated with a nearly 3-fold greater likelihood of bone fractures overall -- and a 9-fold higher risk of hip and spine fractures -- compared with HIV negative people, according to results from a large Danish population study described in the May 1 Journal of Acquired Immune Deficiency Syndromes.

CROI 2014: Vitamin D and Rosuvastatin Improve Bone Loss in People with HIV

A combination of high-dose vitamin D and calcium may help reduce bone loss after starting antiretroviral therapy (ART), according to a presentation at the Conference on Retroviruses and Opportunistic Infections (CROI 2014) last month in Boston. A related study found that rosuvastatin increased hip bone mineral density in HIV positive people on ART, though insulin resistance worsened.

Low CD4 Count Raises Risk of Heart Attack, Bone Loss

HIV positive people whose CD4 T-cell count falls below 200 cells/mm3 are at greater risk for myocardial infarction, though the heart attack rate is not elevated for people with counts of 500 cells/mm3 or more, researchers recently reported. Another study found that people with low CD4 counts have a higher likelihood of bone loss after starting antiretroviral therapy (ART).

CROI 2014: Researchers Discuss HIV, Aging, and Frailty

People living with HIV are at greater risk of geriatric syndromes such as frailty and difficulty with daily activities than HIV negative people of the same age -- and this can have a significant effect upon their quality of life as they age, according to several studies presented at the 14th Conference on Retroviruses and Opportunistic Infections (CROI 2014) last month in Boston.

IDWeek 2013: HIV+ People Not on Antiretrovirals Are Prone to Inflammation-related Bone Loss

HIV positive people not taking antiretroviral therapy experienced more bone mineral density (BMD) loss at the hip and were somewhat more likely to develop osteopenia or osteoporosis than HIV negative individuals, researchers reported at the second IDWeek conference held recently in San Francisco. They also found that bone loss among people with HIV appeared to be linked to inflammation.

CROI 2014: Newborns Exposed to Tenofovir Have Lower Bone Content [VIDEO]

Infants born to women who took tenofovir during pregnancy had significantly lower bone mineral content than babies who were not exposed, according to study findings reported at the 21st Conference on Retroviruses and Opportunistic Infections (CROI 2014) this month in Boston.

Low CD4 Count at Start of HIV Treatment Linked to Greater Bone Loss

People who had low CD4 T-cell counts when they started antiretroviral therapy (ART) were significantly more likely to experience bone loss after ART initiation, especially if they also had high viral load, researchers reported in the August 13, 2013, advance edition of Clinical Infectious Diseases.

IAS 2013: Studies Look at Second-Line Bone Changes, Fractures, and HIV- and HCV-Related Bone Loss

People with HIV experience less bone loss if they switch to a NRTI-sparing second-line regimen containing raltegravir, researchers reported last week at the 7th International AIDS Society Conference on HIV Pathogenesis, Treatment and Prevention (IAS 2013) this week in Kuala Lumpur. Other studies showed that HIV infection is associated with increased risk of hip fractures and shed light on different mechanisms of bone loss associated with HIV and hepatitis C.
