Abstract:
Denosumab (DMAB) is a potent antiresorptive treatment used for treatment of osteoporosis and low bone mineral density (BMD) in those at high risk for fracture. In postmenopausal women with osteoporosis, DMAB treatment for 10 years has been studied, with results showing continued gains in BMD, sustained fracture risk reduction, and low risk of adverse events. However, upon discontinuation of DMAB, there is a rapid reversal of effect, with increase in bone turnover, loss of BMD, and in a subset of patients, a greater risk for multiple vertebral fractures.

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...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

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...
