|Adverse Effects||Associated ARVs||Onset/Clinical Manifestations||Estimated Frequency||Risk Factors||Prevention/ Monitoring||Management|
|Osteopenia and Osteoporosis||Any cART regimen
Specific Agents of Possible Concern:
||Longer duration of HIV infection
Greater severity of HIV disease
Growth delay, pubertal delay
Prolonged systemic corticosteroid use
Minimal weight-bearing exercise
||Ensure sufficient calcium and vitamin D intake.
Encourage weight-bearing exercise.
Reduce modifiable risk factors (e.g., smoking, low BMI, use of steroids, use of medroxyprog-esterone).
Role of bisphosphonates not established in children
Consider change in ARV regimen.
|a Some experts would periodically measure 25-OH-vitamin D, especially in HIV-infected urban youth because, in this population, the prevalence of vitamin D insufficiency is high.
b Until more data are available about the long-term effects of TDF on bone mineral acquisition in childhood, some experts would obtain a DXA at baseline and every 6 to 12 months for prepubertal children and children in early puberty who are initiating treatment with TDF. DXA should also be considered in adolescent women on TDF and medroxyprogesterone and in children with indications not uniquely related to HIV infection (such as cerebral palsy).
Key to Acronyms:ARV = antiretroviral; BMD = bone mineral density; BMI = body mass index; cART = combination antiretroviral therapy; DXA = dual-energy x-ray absorptiometry; LPV/r = ritonavir-boosted lopinavir; PI = protease inhibitor; TDF = tenofovir disoproxil fumarate
