Comparison of the Effect of Denosumab and Alendronate on BMD and Biochemical Markers of Bone Turnover in Postmenopausal Women With Low Bone Mass : A Randomized, Blinded, Phase 3 Trial

Denosumab is a fully human monoclonal antibody that inhibits bone resorption by neutralizing RANKL, a key mediator of osteoclast formation, function, and survival. This phase 3, multicenter, double‐blind study compared the efficacy and safety of denosumab with alendronate in postmenopausal women with low bone mass. One thousand one hundred eighty‐nine postmenopausal women with a T‐score ≤ −2.0 at the lumbar spine or total hip were randomized 1:1 to receive subcutaneous denosumab injections (60 mg every 6 mo [Q6M]) plus oral placebo weekly (n = 594) or oral alendronate weekly (70 mg) plus subcutaneous placebo injections Q6M (n = 595). Changes in BMD were assessed at the total hip, femoral neck, trochanter, lumbar spine, and one‐third radius at 6 and 12 mo and in bone turnover markers at months 1, 3, 6, 9, and 12. Safety was evaluated by monitoring adverse events and laboratory values. At the total hip, denosumab significantly increased BMD compared with alendronate at month 12 (3.5% versus 2.6%; p < 0.0001). Furthermore, significantly greater increases in BMD were observed with denosumab treatment at all measured skeletal sites (12‐mo treatment difference: 0.6%, femoral neck; 1.0%, trochanter; 1.1%, lumbar spine; 0.6%, one‐third radius; p ≤ 0.0002 all sites). Denosumab treatment led to significantly greater reduction of bone turnover markers compared with alendronate therapy. Adverse events and laboratory values were similar for denosumab‐ and alendronate‐treated subjects. Denosumab showed significantly larger gains in BMD and greater reduction in bone turnover markers compared with alendronate. The overall safety profile was similar for both treatments.

Combination Teriparatide and Raloxifene Therapy for Postmenopausal Osteoporosis: Results From a 6-Month Double-Blind Placebo-Controlled Trial†‡

We compared combination treatment with teriparatide plus raloxifene with teriparatide alone in women with postmenopausal osteoporosis in a 6‐month double‐blind, placebo‐controlled trial that measured biochemical markers of bone turnover and BMD. Markers of bone formation and spine BMD increased similarly with teriparatide alone and combination therapy. However, combination therapy induced a significantly smaller increase in bone resorption versus teriparatide alone and significantly increased total hip BMD versus baseline.

Prevalence of oral glucocorticoid usage in the United States: A general population perspective

There is little information on oral glucocorticoid use in the general US population. Previously, there have been published estimates of glucocorticoid use in countries outside of the US. This study aimed to estimate the prevalence of glucocorticoid use, duration of use, and concomitant use of antiosteoporosis pharmaceuticals in the US population age ≥20 years.

Bone Loss in Rheumatoid Arthritis: Systemic, Periarticular, and Focal

Rheumatoid arthritis is a chronic inflammatory disease that results in generalized bone loss and increased fracture risk. Characteristic radiologic features of rheumatoid arthritis include periarticular osteopenia and marginal erosions. An emerging literature highlights the importance of osteoclasts as mediators of the erosive process, with an impairment of bone formation by inhibition of the Wnt signaling pathway as a cause of lack of repair of erosions. MRI has demonstrated the importance of inflammation in the bone marrow compartment as a cause of periarticular osteopenia. The term osteoimmunology has evolved to highlight the association between cells and cytokines of the immune system and their relationship to bone metabolism in rheumatoid arthritis and other forms of chronic inflammatory arthritis.

Osteoporosis in elderly: prevention and treatment.

Osteoporosis is a major clinical problem in older women and men. Almost any bone can fracture as a result of the increased bone fragility of osteoporosis. These fractures are associated with higher health care costs, physical disability, impaired quality of life, and increased mortality. Because the incidence of osteoporotic fracture increases with advancing age, measures to diagnose and prevent osteoporosis and its complications assume a major public health concern. BMD is a valuable tool to identify patients at risk for fracture, to make therapeutic decisions, and to monitor therapy. Several other modifiable and nonmodifiable risk factors for osteoporosis have also been identified. Treatment of potentially modifiable risk factors along with exercise and calcium and vitamin D supplementation forms an important adjunct to pharmacologic management of osteoporosis. Improved household safety can reduce the risk of falls. Hip protectors have been found to be effective in nursing home population. The pharmacologic options include bisphosphonates, HRT, SERMs and calcitonin. PTH had received FDA advisory committee approval. Alendronate has been approved for treatment of osteoporosis in men, and other treatments for men are under evaluation.

The Official Positions of the International Society for Clinical Densitometry: Vertebral Fracture Assessment

Vertebral fracture assessment (VFA) is a low-cost method of accurately identifying individuals who have clinically unrecognized or undocumented vertebral fractures at the time of bone density test. Because prevalent vertebral fractures predict subsequent fractures independent of bone mineral density and other clinical risk factors, their recognition is an important part of strategies to identify those who are at high risk of fracture, so that prevention therapies for those individuals can be implemented. The 2007 Position Development Conference developed detailed guidelines regarding the indications for acquisition of, and interpretation and reporting of densitometric VFA tests. The purpose of the 2013 VFA Task Force was to simplify the indications for VFA yet keep them evidence based. The Task Force reviewed the literature published since the 2007 Position Development Conference and developed prediction models based on 2 large cohort studies (the Study of Osteoporotic Fractures and the Osteoporotic Fractures in Men Study) and the densitometry database of the University of Chicago. Based on these prediction models, indications for VFA were reduced to a simplified set of criteria based on age, historical height loss, use of systemic glucocorticoid therapy, and self-reported but undocumented prior vertebral fracture.

The Role of Selective Estrogen Receptor Modulators in the Prevention and Treatment of Osteoporosis

Osteoporosis can affect almost everyone in the population, and although clinical outcome of fracture is manifested in late life, the disease process begins in the early postmenopausal years in women. The pharmacologic agents currently available for osteoporosis prevention and treatment act by inhibiting bone resorption, and include estrogen or hormone replacement therapy (estrogen with progestin), bisphosphonates, salmon calcitonin nasal spray, and selective estrogen receptor modulators (SERMs). Raloxifene is a benzothiophene SERM that has estrogen against effects in bone and on serum lipid metabolism and estrogen antagonist effects on breast and uterine tissue. This article summarizes the effects of these antiresorptive agents, as measured by changes in bone mineral density, biochemical markers of bone turnover, and incident fractures in postmenopausal osteoporosis.

United States Adults Meeting 2010 American College of Rheumatology Criteria for Treatment and Prevention of Glucocorticoid‐Induced Osteoporosis

The American College of Rheumatology (ACR) updated its guidelines on the prevention and treatment of glucocorticoid‐induced osteoporosis (GIO) in 2010. An unknown proportion of US adults at risk of fracture due to glucocorticoid use would be recommended antiosteoporosis pharmaceutical (AOP) therapies based on the ACR guidelines.

A 21-year-old man with Still's disease with fever, rash, and pancytopenia

History of the present illness A 21-year-old man with a history of adult-onset Still’s disease (AOSD) presented to the emergency room with a 10-day history of fever with a maximum temperature of 40°C, headaches, joint pain, rash, and vomiting. His rheumatologist advised him to stop taking adalimumab until any underlying infection was ruled out. He was thought to have a flare of Still’s disease and was advised to continue methotrexate (MTX) and prednisone 60 mg daily. He did not improve and after 3 days was admitted and given intravenous methylprednisolone (IVMP). He initially felt better, but when the dose of IVMP was decreased, joint pain, fever, and rash returned. Laboratory tests from the initial admission are shown in Table 1. Peripheral blood smear showed atypical lymphocytes. Creatine kinase, hepatitis panel, and chest radiograph were unremarkable.
