Currently marketed inhibitors of bone resorption or stimulators of bone formation have significantly contributed to a better preventive and therapeutic approach to postmenopausal and senile osteoporosis. However, none of the available compounds has unequivocally demonstrated an ability to fully prevent the occurrence of new vertebral or peripheral osteoporotic fractures once the disease is established. Therefore, several new medications are being developed, with the aim of providing a better risk-benefit profile and/or a more favourable cost-utility assessment than available drugs. Potential inhibitors of bone resorption include specific inhibitors of the osteoclast's proton pump, inhibitors of prostaglandins or nitric oxide donors. Stimulators of osteoblastic activity and subsequent bone formation might be obtained by strontium salts, peptides of the parathyroid hormone family, growth hormone and insulin-like growth factors or bone morphogenetic proteins. Most of these compounds are now undergoing phase II/III development programmes, and results evaluating their potential benefit should be available within 1 to 5 years. [less ▲]

Navicular bones from the four limbs of 95 horses, classified in 9 categories, were studied. The effects of age on navicular bone morphometry and histomorphometry were estimated, after adjustment of the data to even out the effects of front and rear limbs, morphometrical type, sex, weight, and size. All the external measurements of the navicular bone decreased significantly with increasing age. From the histomorphometrical data, cortical bone volume decreased with age in most horses, whereas cancellous bone volume and, in particular, the marrow spaces increased. The increase in the cancellous bone volume could have resulted from tunnelling of the internal part of the cortex, which converted it progressively into a porous trabecular-like structure. Trabecular bone volume also decreased with age and the trabecular lattice changed dramatically to become disconnected in aged horses. These observations corresponded closely to those reported for ageing of the skeletal system in humans. However, in sporting horses, the navicular cortical bone volume increased with age and the cancellous bone volume decreased. Exercise appeared to have decreased bone resorption and increased bone formation at the endocortical junction. The cancellous bone architecture was also improved. in that the trabecular lattice and trabecular bone volume remained unchanged in aged sporting horses. Our findings confirmed that exercise may be good practice to prevent age-related bone loss. [less ▲]

The aim of this study was to assess the efficiency of a self-administered questionnaire to identify subjects with postmenopausal osteoporosis in the setting of first line medical care. A sample of 300 postmenopausal women completed the questionnaire based on 18 items. Bone mineral density at the lumbar spine (BMD-L), total hip (BMD-H), and femoral neck (BMD-N) was used as objective criterion for evaluation. The mean risk score was 8.2 +/- 3.21. BMD was correlated with total risk score: r = -0.32 for BMD-L, -0.36 for BMD-N, and -0.43 for BMD-H. Cutoff points for the risk score (equal likelihood points) according to a T-score threshold of -2.5 were 8.6 for BMD-L and BMD-N and 9.3 for BMD-H; specificity and sensitivity was 62% and 62%, respectively, for BMD-L, 65% and 62% for BMD-N, and 75% and 63% for BMD-H. Stepwise multiple regression analysis of the questionnaire items in relation to BMD showed higher correlation coefficients for models including individual items rather than the overall risk score. Items concerning low weight, older age, and wrist fracture after 50 years of age were always selected as significant determinants of BMD (R = 0.43-0.55). Hormonal replacement therapy was also an important determinant. Lifestyle-related items did not contribute significantly. In conclusion, the diagnostic performance of the 18-item self-administered questionnaire was poorer than a shortened questionnaire omitting lifestyle factors. The clinical utility of a questionnaire should ultimately be evaluated in the specific optic of a chosen global strategy for prevention of osteoporotic fractures. [less ▲]

The present study was designed to visit elderly women living in nursing homes and to compare their femoral neck bone mineral density (BMD) and circulating levels of parathyroid hormone (PTH) and 25-OH vitamin D (25-OHD) with those of subjects living at home, in the immediate vicinity of the nursing homes. Of 1483 women, aged 70 years and older, who were selected, 993 agreed to participate in this trial. Their femoral neck BMD (n = 993) was measured by dual-energy X-ray absorptiometry, with a specific device installed in a mobile truck. The circulating levels of 25-OHD and PTH were assessed after an overnight fast (n = 748). After stratification for age, there were no significant differences in mean femoral neck BMD values, prevalence of femoral neck osteoporosis, mean serum 25-OHD and prevalence of absolute or relative 25-OHD deficiency between the two groups. Serum levels of PTH were significantly higher in women over 80 years old living in nursing homes, compared with the community-dwelling women. After adjustment for age, a significant relation was found between femoral neck BMD and PTH levels in the whole population (p = 0.004) and in community-dwelling subjects (p = 0.039). When stratifying our population by quartiles of serum PTH values, the odds ratios for femoral neck osteoporosis were significantly increased for the top two quartiles compared with the lowest one both before (p = 0.00146) and after (p = 0.0013) adjustment for age and type of housing. From this study we conclude that femoral osteoporosis is largely underestimated in European women. Living in a nursing home is not, per se, a risk factor for decreased femoral BMD, and circulating PTH levels are a key determinant of low femoral bone density and osteoporosis. [less ▲]

In the past years, there has been a multiplication of drugs identified as candidates for use in the prevention or the treatment of osteoporosis. When treating established osteoporosis, the objective is to prevent further skeletal deterioration, improve bone mass and/or bone microarchitecture to provide a documented reduction of the risk of vertebral and/or peripheral fractures. Calcium and vitamin D have been shown to be particularly efficient in elderly patients, mainly to prevent non-vertebral fractures. By inhibiting osteoclastic activity, calcitonin improves bone mineral density at all sites. Preliminary results suggest that it might also decrease vertebral fracture rates. Bisphosphonates have been investigated for 20 years in the treatment of osteoporosis. Alendronate was shown to reduce spinal and extravertebral fractures. New formulations of fluoride, like monofluorophosphate appear to be particularly beneficial in women with mild to moderate osteoporosis. Several new compounds, including parathormone, strontium salts, ipriflavone or others are currently developed and subject to large investigational programs to demonstrate their ability to reduce fracture.
