Osteoporosis in Men - Article

ABSTRACT: Osteoporosis in men is now recognized as an increasingly important public health issue. About 30 percent of hip fractures occur in men, and one in eight men older than 50 years will have an osteoporotic fracture. Because of their greater peak bone mass, men usually present with hip, vertebral body, or distal wrist fractures 10 years later than women. Hip fractures in men, however, result in a 31 percent mortality rate at one year after fracture versus a rate of 17 percent in women. Major risk factors for osteoporosis in men are glucocorticoid use for longer than six months, osteopenia seen on plain radiographs, a history of nontraumatic fracture, hypogonadism, and advancing age. Bisphosphonates and teriparatide (recombinant parathyhroid hormone) have recently been approved for use in men and should be considered along with supplemental calcium and vitamin D. Increased awareness by physicians of risk factors for male osteoporosis--and early diagnosis and treatment--are needed to decrease the morbidity and mortality resulting from osteoporotic fractures.


Pharmacologic Prevention of Osteoporotic Fractures - Article

ABSTRACT: Osteoporosis is characterized by low bone mineral density and a deterioration in the microarchitecture of bone that increases its susceptibility to fracture. The World Health Organization defines osteoporosis as a bone mineral density that is 2.5 standard deviations or more below the reference mean for healthy, young white women. The prevalence of osteoporosis in black women is one half that in white and Hispanic women. In white women 50 years and older, the risk of osteoporotic fracture is nearly 40 percent over their remaining lifetime. Of the drugs that have been approved for the prevention or treatment of osteoporosis, the bisphosphonates (risedronate and alendronate) are most effective in reducing the risk of vertebral and nonvertebral fractures. Risedronate has been shown to reduce fracture risk within one year in postmenopausal women with osteoporosis and in patients with glucocorticoid-induced osteoporosis. Hormone therapy reduces fracture risk, but the benefits may not outweigh the reported risks. Teriparatide, a recombinant human parathyroid hormone, reduces the risk of new fractures and is indicated for use in patients with severe osteoporosis. Raloxifene has been shown to lower the incidence of vertebral fractures in women with osteoporosis. Salmon calcitonin is reserved for use in patients who cannot tolerate bisphosphonates or hormone therapy.


Prevention of Osteoporosis and Fractures - Article

ABSTRACT: Osteoporosis and low bone density are associated with a risk of fracture as a result of even minimally traumatic events. The estimated lifetime risk of osteoporotic fracture is as high as 50 percent, especially in white and Asian women. The use of caffeine, tobacco and steroids is associated with a decrease in bone density. Cognitive impairment, vision problems and postural instability increase the risk of falling and sustaining a fracture. Medications such as long-acting sedative hypnotics, anticonvulsants and tricyclic antidepressants also increase this risk. Combinations of clinical and radiographic findings can predict fracture risk more effectively than bone densitometry, but often only after the first fracture has occurred. The addition of dietary calcium and/or vitamin D is clearly both cost-effective and significant in reducing the likelihood of fractures. Bisphosphonates reduce fracture risk but at a cost that may be prohibitive for some patients. Estrogen and estrogen-receptor modulators have not been well studied in randomized trials evaluating the reduction of fractures, but they are known to increase bone density. Pharmacologic therapy and the reduction of sensory and environmental hazards can prevent osteoporotic fractures in some patients.


Bisphosphonates: Safety and Efficacy in the Treatment and Prevention of Osteoporosis - Article

ABSTRACT: Osteoporosis affects more than 28 million Americans. With the advent of accessible and affordable diagnostic studies, awareness and recognition of this disease by patients and clinicians are growing. Osteoporotic fractures of the spine and hip are costly and associated with significant morbidity and mortality. Over the past decade, a surge of new antiosteoporotic drugs have been labeled or are awaiting labeling by the U.S. Food and Drug Administration. One class of agents used to treat osteoporosis is the bisphosphonates, which inhibit bone resorption, cause an increase in bone mineral density and reduce the risk of future fractures caused by aging, estrogen deficiency and corticosteroid use. Overall, bisphosphonates have been shown to have a strong safety and tolerability profile.
