Insights
A high prevalence of decreased bone mineral density was observed in HIV-infected children on highly active antiretroviral therapy (HAART). Further research is needed to understand the causes and associated factors of these bone alterations.
Area of Science:
- Pediatric infectious diseases
- Bone metabolism and endocrinology
- HIV/AIDS management
Context:
- Highly active antiretroviral therapy (HAART) has improved outcomes for children with HIV.
- However, concerns exist regarding potential long-term metabolic and bone health complications.
- This study investigates bone health in a pediatric HIV cohort on HAART.
Purpose:
- To determine the prevalence of bone mineral density (BMD) alterations in HIV-infected children receiving HAART.
- To identify potential factors associated with decreased BMD in this population.
- To assess the rates of osteopenia and osteoporosis in the studied cohort.
Summary:
- Bone dual energy X-ray absorptiometry (DEXA) was conducted on 50 HIV-infected children on HAART.
- Forty percent exhibited reduced BMD, with 36% diagnosed with osteopenia and 4% with osteoporosis.
- No significant associations were found between decreased BMD and analyzed factors.
Impact:
- Highlights a significant prevalence of decreased bone mineral density in pediatric HIV patients on HAART.
- Underscores the need for further investigation into the etiology and risk factors for these bone abnormalities.
- Informs clinical monitoring and management strategies for HIV-infected children undergoing long-term HAART.
Background:
In developed countries, the introduction of highly active antiretroviral therapy (HAART) has greatly improved survival and quality of life in HIV-infected children. Nevertheless, worrisome metabolic and bone alterations are beginning to be observed.
Objective:
To evaluate the prevalence of alterations in bone mineral density and possible associated factors in a cohort of HIV-infected children receiving HAART.
Patients And Methods:
Bone dual energy X-ray absorptiometry (DEXA) was performed in 50 HIV-infected children in a tertiary hospital in Madrid after a median length of HAART of 54 months. Subsequently, the group with bone mineral loss was compared with the group without bone mineral loss.
Results:
Forty percent of the children studied had decreased bone mineral density, of which 36 % had osteopenia (18/50) and 4 % had osteoporosis (2/50). No statistically significant differences were found between the two groups in any of the factors analyzed.
Conclusions:
The prevalence of decreased bone mineral density in our cohort of HIV-infected children receiving HAART is high. The etiology and factors associated with this alteration are still not well known.

Bone Remodeling
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
