Abstract:
Bone loss is a frequent side effect of androgen deprivation therapy, which leads to a significant number of pathologic fractures. Prevention of osteoporosis aims at reducing skeletal-related events. The RANK ligand antibody denosumab and bisphosphonates are used for this indication. Denosumab has been shown to increase bone density and to reduce the incidence of fractures at any location by 72%. Bone density can also be increased by bisphosphonates; however, there is no conclusive evidence so far that the fracture rate can be reduced significantly. Therefore guidelines do not recommend use of these substances for this indication.

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...

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...
