Prevention of glucocorticoid-induced osteoporosis.
Glucocorticoid-induced osteoporosis is the most common cause of secondary osteoporosis. The role of the Wnt signaling pathway in bone formation and the ratio of receptor activator for NF-kappaB ligand versus osteoprotegerin in bone resorption are exciting new insights. The absolute fracture risk helps both clinicians and patients to interpret the results of bone density measurement, which may have a positive influence on adherence to therapy. The bisphosphonates alendronate and risedronate are the first-line treatment in the prevention of glucocorticoid-induced osteoporosis, because both increase the bone mineral density of the spine and hips and reduce the vertebral fracture rate. Treatment with the anabolic agent parathyroid hormone (1 - 34) strongly stimulates bone turnover, and seems to be superior to treatment with alendronate. It might be attractive for glucocorticoid-treated patients with new vertebral fractures during treatment with bisphosphonates, and/or with severe fracture risk.
