Summary
HIV patients have an increased risk of osteoporosis and fractures due to multifactorial causes including viral infection and antiretroviral therapy. Current guidelines recommend screening based on age and risk factors, with no specific treatment changes advised.
Area of Science:
- Infectious Diseases
- Endocrinology
- Geriatrics
Context:
- Combination antiretroviral therapy has significantly increased HIV patient lifespan.
- This has led to a rise in non-AIDS-defining conditions, including metabolic disorders and malignancies.
- HIV patients exhibit a higher incidence of osteoporosis and bone fractures compared to the general population.
Purpose:
- To summarize the multifactorial causes of increased osteoporosis and fracture risk in HIV patients.
- To review current screening guidelines for low bone density in HIV-infected individuals.
- To discuss the association between antiretroviral drugs and bone health.
Summary:
- Bone density loss in HIV patients stems from traditional risk factors, HIV infection itself (affecting bone remodeling), and to a lesser extent, antiretroviral drugs like Tenofovir.
- Studies suggest an association between certain antiretrovirals and bone density reduction, but definitive evidence for increased fracture risk is lacking.
- Screening recommendations vary, with US guidelines focusing on patients over 50 with risk factors, while European guidelines suggest screening all HIV patients over 50.
Impact:
- Highlights the need for comprehensive bone health assessment in the aging HIV population.
- Informs clinical practice regarding osteoporosis screening and management in HIV patients.
- Underscores the importance of considering both viral and treatment-related factors in managing bone health in HIV.

01:29Bone Disorders
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
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...

01:24Chronic Kidney Disease II: Clinical Manifestations
Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...
01:29Pulmonary Tuberculosis I
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
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.

01:02What is the Skeletal System?
Overview
01:22The Functions of the Skeletal System
The most apparent functions of the skeletal system are support, protection, and movement. However, bone tissue also performs several other critical metabolic functions. For one, the bone matrix acts as a reservoir for a number of minerals important to the functioning of the body, especially calcium and phosphorus. These minerals, present in the bone tissue, can be released back into the bloodstream when required. Calcium ions, for example, are essential for muscle contractions and controlling...
01:25Role of Vitamins in Maintaining Bone Health
The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
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...
