Osteoporosis presents a substantial public health challenge, contributing significantly to morbidity and mortality through fractures. While postmenopausal osteoporosis is common, secondary osteoporosis affects a significant number of patients, including over 30% of postmenopausal and 50-80% of men. People living with HIV (PLWH) experience age-related medical comorbidities earlier and more extensively than those without HIV. The compromised bone health in PLWH is attributed to factors associated with the virus, antiretroviral therapy (ART) side effects, and health disparities such as inadequate nutrition, low body weight, hypogonadism, vitamin D deficiency, and increased recreational substance use. More recently, it has become apparent that vertebral fractures are more common in PLWH, with a prevalence of 11.1% and a 2.30-fold more significant risk than the general population. Low bone mass density (BMD) is twice as common in PLWH, increasing to 3 times as common in PLWH on ART. ART initiation leads to transient bone loss with nucleotide reverse transcriptase inhibitors such as tenofovir disoproxil fumarate (TDF) and protease inhibitors, causing higher BMD loss. In contrast, integrase and specific reverse-transcriptase inhibitors have minimal adverse effects on BMD. The newer formulation, tenofovir alafenamide (TAF),…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
