jules levin, NATAP: HIV/AIDS, gender & bone loss (0059)



GENDER AND GONADAL FUNCTION DIFFERENCES IN THE PREVALENCE OF BONE MASS REDUCTION: higher rates of osteopenia and osteoporosis for men vs women and at early ages, in their 40s.

This report underlines that HIV related bone disease in men and women may be different, natural history of BMR according to gender is unknown. …

This large case series shows an unexpected high prevalence of trabecular bone mass reduction in men. …..This report underline that HIV related bone disease in men and women may be different, natural history of BMR according to gender is unknown…..the table below shows osteopenia in 37% of men vs 23% in women, the difference is statistically significant. Osteoporosis prevalence was 16% in men vs 9% in women, also statistically significant. Of note, the average ages were 45-48 for men and 41-50 for women, very young to have so much prevalence of bone loss…..Both hypogonadal and eugonadal men categories were independent predictors of BMR in comparison to menopausal women…….We hypothesize it is necessary to move to a tissue level (a plausible difference of enzymatic activity of amortize has been previously suspected by our group) to understand the pathophysiological mechanism of gender difference in BMR

In HIV un-infected subjects, no differences are seen in the rate of bone mass loss until the onset of menopause, when women show a faster and more pronounced reduction of BMD than men due to lack of estrogens. We hypothesized that a gender difference in the prevalence and the natural history of bone disease may help to generate new pathogenic hypotheses in order to explain the high prevalence of BMR in HIV infected patients.

Thyroid Dysfunction, Hypogonadism, Testosterone,
Bone, Prostate Cancer, HIV & HAART …..“Testosterone: Hypogonadism is more prevalent in the HIV-positive population, with prevalence rates about 20% higher than age-matched controls.37 The etiology of this Hypogonadism is unclear but may be related to a combination of factors, including HIV, HAART, malnutrition and opportunistic infections. Hypogonadism may result in or contribute to reduced bone mineral density and muscle mass, poor mood, anemia, decreased libido and erectile dysfunction
