Osteoporosis is a leading cause of debility and declining quality of life in postmenopausal women worldwide. Treatment of osteoporosis has been ubiquitous throughout the developed world since the mid-1990s, most notably with the introduction of bisphosphonates in 1995. Nonetheless, the incidence of hip fractures increased by 25% between 1990 and 2000, despite advances in osteoporosis therapy. Studies indicate that bone density increases over the first 3 years of bisphosphonate therapy and then plateaus or perhaps even declines, placing these patients at greater risk of fracture. Since hip fractures are associated with increased morbidity, mortality, and increased cost of health care, improvements in treating osteoporosis are critical. Denosumab is a novel monoclonal antibody targeted against the receptor activator of nuclear factor-κB ligand (RANKL) that inhibits osteoclast activity. Initial data suggest that denosumab increases bone mineral density for greater than 3 years. Of greater importance, denosumab has been shown to decrease vertebral fractures by 68%, nonvertebral fractures by 19%, and hip fractures by 42% for at least 36 months. Data also indicate that the safety profile of denosumab is equivalent to other drugs used in osteoporosis management, but potential risks of immunosuppression and cancer have been hypothesized.

Abstract Background Osteoporosis is a serious disease that causes bone fragility fractures and increases mortality. Bisphosphonates are the first-line drugs for osteoporosis. However, the gains in bone mineral density by use of bisphosphonates alone are limited. Case presentation We describe the clinical outcome of a Japanese woman with osteoporosis treated with bisphosphonates after multiple spinal fractures. After 3 years of treatment with the bisphosphonate alendronate, her lumbar bone mineral density and bilateral hip bone mineral density markedly increased by 61.9% and 32.5%, respectively. Conclusion We considered that our patient’s multiple fractures had caused a decrease in bone mineral density, which naturally improved with fracture healing to enhance the increase in bone mineral density with bisphosphonate treatment.

The objective of this study was to estimate the comparative effectiveness of bisphosphonate therapy on bone mineral density (BMD) in patients with corticosteroid-treated Duchenne muscular dystrophy (DMD). A retrospective, comparative effectiveness study evaluating changes in BMD and fragility fractures in patients with DMD presenting to British Columbia Children’s Hospital from 1989 to 2017 was conducted. Marginal structural generalized estimating equation models weighted by stabilized inverse-probability of treatment weights were used to estimate the comparative effectiveness of therapy on BMD. Of those treated with bisphosphonates (N = 38), 7 (18.4%), 17 (44.7%), and 14 (36.8%) cases were treated with pamidronate, zoledronic acid, or a combination of both, respectively, while 36 cases of DMD were untreated. Mean age of bisphosphonate initiation was 9.2 (SD 2.7) years. Mean fragility fractures declined from 3.5 to 1.0 following bisphosphonate therapy. Compared to the treated group, the untreated group had an additional 0.63-SD decrease (95% confidence interval [CI]: −1.18, −0.08, P = .026) in total BMD and an additional 1.04-SD decrease (95% CI: −1.74, −0.34; P = .004) in the left hip BMD, but the change in lumbar spine BMD (0.15, 95% CI: −0.36, 0.66; P = .57) was not significant. Bisphosphonate therapy may slow the decline in BMD in boys with corticosteroid-treated DMD compared to untreated counterparts. Total number of fragility fractures decreased following bisphosphonate therapy.
