Akimitsu Miyauchi
Teriparatide(recombinant human PTH1-34, 20 μg daily subcutaneous injection)has been approved for osteoporosis patients at high risk of fracture in many countries including Japan. Teriparatide daily injection therapy has been reported to increase BMD, improve microarchitecture of bone, and reduce the risk of new vertebral fractures and that of non-vertebral fractures. Pharmakokinetic(PK)study after a single Teriparatide injection of the daily dose in healthy Japanese postmenopausal women(n=18)revealed very rapid achievement of peak blood level(median of tmax=0...

The effect of germinated Superhongmi, a reddish brown pigmented rice cultivar, on the glucose profile and bone turnover in the postmenopausal-like model of ovariectomized rats was determined. The ovariectomized Sprague-Dawley rats were randomly divided into three dietary groups (n = 10): normal control diet (NC) and normal diet supplemented with non-germinated Superhongmi (SH) or germinated Superhongmi (GSH) rice powder. After eight weeks, the SH and GSH groups showed significantly lower body weight, glucose and insulin concentrations, levels of bone resorption markers and higher glycogen and 17-β-estradiol contents than the NC group...

BACKGROUND AND OBJECTIVES: Recently, the osteoporosis treatment has attracted attention, and several drugs have been developed. Among these, bisphosphonates (BPs), parathyroid hormone (PTH) and anti-receptor activator of nuclear factor kappa B ligand (RANKL) monoclonal (MAb) denosumab (DMAb) are the major osteoporosis agents. Several studies demonstrated that the effect of osteoporosis agents is evaluated by lumar or hip dual energy X-ray absorptiometry (DXA). However, private clinic commonly use the radial DXA...

BACKGROUND: We have recently identified interleukin 1B (IL-1B) as a potential biomarker for predicting breast cancer patients at increased risk for developing bone metastasis. In mouse models, IL-1B and its receptor (IL-1R1) are upregulated in breast cancer cells that metastasise to bone compared with cells that do not. We have now investigated the functional role of IL-1 by blocking IL-1R signalling with the clinically licensed antagonist, anakinra. METHODOLOGY: 6-week old female BALB/c mice received a subcutaneous or intra-venous injection of MDA-MB-231-IV or MCF7 cells...

Systemic Mastocytosis has been long identified as a potential cause of osteoporosis; nevertheless, data regarding longitudinal variation of bone mineral density (BMD) in patients with indolent systemic mastocytosis (ISM) are missing . We studied BMD variation at lumbar spine and proximal hip after 30-month (±6 months) follow-up in a large cohort of patients (83) with ISM without osteoporosis, supplementated with vitamin D and/or calcium when needed. We also analyzed the correlation between variation of BMD, basal serum tryptase levels and bone turnover markers (BTM)...

Bone strength - and, hence, fracture risk - reflects the structural and material properties of the skeleton, which changes with bone turnover during aging and following effective pharmacotherapy. A variety of powerful new techniques (quantitative computed tomography, as well as peripheral quantitative computed tomography and high-resolution peripheral quantitative computed tomography) provide precise images of bone structure and can be used to model the response of specific bones to different types of mechanical load...

Cow's milk is often severely criticized as a cause of multiple health problems, including an increased risk of fractures. A close look at the scientific literature shows a striking contradiction. On the one hand, experimental studies of surrogate markers (e.g., bone turnover markers and bone mineral density [BMD]) usually indicate benefits from drinking cow's milk. On the other, the findings from epidemiological studies are conflicting and disconcerting. In all age groups, including children and postmenopausal women, consuming cow's milk, powdered milk supplements, or whey protein is associated with a slower bone turnover and unchanged or higher BMD values...

Prolonged glucocorticoid (GC) administration causes secondary osteoporosis (GIOP) and non-traumatic osteonecrosis. LLP2A-Ale is a novel bone-seeking compound that recruits mesenchymal stem cells to the bone surface, stimulates bone formation, and increases bone mass. The purpose of this study was to determine if treatment with LLP2A-Ale alone or in combination with parathyroid hormone (PTH) could prevent or treat GIOP in a mouse model. Four-month-old male Swiss-Webster mice were randomized to a prevention study with placebo, GC (day 1-28), and GC + LLP2A-Ale (IV, day 1) or a treatment study with placebo, GC (days 1-56), GC + LLP2A-Ale (IV, day 28), GC + PTH, and GC + LLP2A-Ale + PTH (days 28-56)...

Many previous reports have indicated that atypical femur fractures (AFFs) are associated with the administration of bisphosphonates (BPs). A number of risk factors and hypotheses regarding the pathogenesis of AFFs have been reported to date. The purpose of the present study was to identify the factors associated with AFFs in Japanese individuals and to elucidate the association between bone metabolism and AFFs by evaluating bone turnover markers (BTMs). We prospectively reviewed all patients with femur fractures and identified the patients with AFFs and typical femur fractures (TFFs)...
