    The European Parliament presented June 10th in Brussels the 'Osteoporosis Report in EU--Means for Prevention'. It was emphasized that in the EU more than 3500 million Ecu have to be spent for hospitalization and that more than 500,000 hospitals beds are being used by osteoporotic patients. According to some calculations this number will double within the next 50 years. The EU has set up eight steps to be considered, e.g. have densitometric measurements available for persons with high risk and have these measurement paid by the insurances to further finance and support research for the very important areas of prevention and treatment. One distinguishes between primary, secondary and tertiary prevention of osteoporosis. Primary prevention aims at reaching at adolescent age a peak bone mass as high as possible. Secondary prevention aims at reducing bone loss peri- and postmenopausal. The tertiary prevention with manifest osteoporosis aims at preventing fractures. Emphasis of the primary prevention is, besides a sufficient calcium intake, to omit risk factors; with secondary prevention the use of medical treatments such as estrogens/gestagens, bisphosphonates, and recently also SERMs is applied. The tertiary prevention tries mostly to reduce the femur fractures. In addition to drugs such as vitamin D/calcium, vitamin D metabolites and bisphosphonates it is very important to create 'a fall-proof home'. Also very useful are hip protectors. PMID:9865147

    Osteoporosis is a major cause of morbidity in post-menopausal women. Strategies to prevent or delay bone loss in normal post-menopausal women and to reduce the risk of fractures in women with osteoporosis are within the scope of family practice. Certain factors, such as inadequate calcium intake, estrogen deficiency, cigarette smoking and lack of physical activity can be modified in peri- and post-menopausal women. For patients with osteoporosis, there is potential for lowering the risk of fractures by means of calcium supplements or other therapies, physical training and rehabilitation, and modification of factors associated with risk of falling.

    Osteoporosis, main risk factor for suffering fragility fractures, is an important public health problem which has undoubted social, health and economic impact; but mainly causes pain, functional limitation and severe alterations in the patient's quality of life. Its current prevalence is very high and a further increase is expected due to a higher life expectancy and the progressive ageing of the population. In the prevention of osteoporosis, the main goal is to prevent fragility fractures; for this reason, it is necessary to: 1) promote bone formation in youth, to get sufficient bone mass peak, 2) reduce bone loss in adulthood, especially after menopause, 3) maintain bone health throughout life, and 4) prevent falls. There is enough evidence that multifactorial strategies (assessment of risk factors, healthy lifestyle habits, smoking cessation, moderation in alcohol consumption, physical exercise, outdoor activity with prudent exposure to sunlight, and a varied and balanced diet), are effective in the population at risk. Regarding factors for the prevention of osteoporosis, current recommendations are: increased consumption of calcium, phosphorus, magnesium and fluoride; provide adequate vitamin D (even with fortified food if necessary); consumption of foods rich in omega-3 acids; reduction of salt and prepared ready meals; sufficient but moderate intake of protein and, in the absence of intolerance, promote the consumption of milk and dairy products, especially yogurt and fermented milk products.

    Abstract Osteoporosis, defined as low bone mass leading to increased fracture risk, is a major health problem that affects approximately 10 million Americans. The aging U.S. population is predicted to contribute to as much as a 50% increase in prevalence by 2025. Although common, osteoporosis can be clinically silent, and without prevention and screening, the costs of osteoporotic fracture–related morbidity and mortality will burden the U.S. healthcare system. This is a particularly relevant concern in the context of diminishing health care resources. Dual-energy X-ray absorptiometry is the most widely used, validated technique for measuring bone mineral density (BMD) and diagnosing osteoporosis. Cost-effectiveness analyses support early detection and treatment of high-risk patients with antiresorptive medications such as bisphosphonates. Moreover, optimization of bone health throughout life can help prevent osteoporosis. Current guidelines recommend screening women by age 65 years, but because no guidelines for screening intervals exist, decisions are made on the basis of clinical judgment alone. Although the recent literature provides some guidance, this review further explores current recommendations in light of newer evidence to provide more clarity on prevention, screening, and management strategies for patients with osteoporosis in the primary care setting.

    Osteoporosis is a condition characterized by low bone mineral density, microarchitectural deterioration of bone tissue, and a consequent increase in fracture risk. The public health impact of osteoporosis stems from its association with fractures of the hip, spine and forearm. Between 10 and 20 percent of hip fracture patients die within a year of the event, and among those who survive, almost two-thirds remain disabled. The medical costs of osteoporosis and its attendant fractures have been placed at 5.2 billion dollars each year in the US and 615 million pound sterling each year in the UK. In Asia, osteoporosis is rapidly becoming a major public health problem with an increasing incidence of hip fracture and a rapidly aging population. By the year 2050, more than half of the hip fracture around the world would occur in Asia, with the total number approaching 3.2 million. Osteoporosis can be attributed to both genetic factors and environmental factors. While it is difficult to modify genes, much can be done to prevent osteoporosis in our every day life. These are discussed below. PMID:15577003

  9. To prevent the osteoporosis playing in advance

    2013-01-01

    Summary There are several possibilities for the prevention of primary, secondary and tertiary osteoporosis but till now they have not been promoted enough and bone fragility is thought about only after the onset of a fracture (tertiary prevention). By recent studies and discoveries it is becoming increasingly clear that there is a relationship between growth and development in early childhood and bone health in old age. Suboptimal bone development leads to a reduction in peak bone mass, and a higher risk of osteoporotic fracture later in life. Preventative strategies against osteoporosis can be aimed at either optimizing the peak bone mass obtained, or reducing the rate of bone loss. Optimization of peak bone mass may be more amenable to public health strategies. Technological advances and our knowledge of osteoporosis have increased in the last decade and so tertiary prevention should be considered a failure in the field of public health. If we want to make advances in the osteoporotic field, we must start in childhood, before the bone mass peak is reached and the gold-standard is starting with prevention as soon as possible, also during fetal development.

    2014-01-01

    In the beginning, that is from the 1960's, when a link between menopause and osteoporosis was first identified; estrogen treatment was the standard for preventing bone loss, however there was no fracture data, even though it was thought to be effective. This continued until the Women's Health Initiative (WHI) study in 2001 that published data on 6 years of treatment with hormone therapy that showed an increase in heart attacks and breast cancer. Even though the risks were small, 1 per 1500 users annually, patients were worried and there was a large drop off in estrogen use. In later analyses the WHI study showed that estrogen reduced fractures and actually prevented heart attacks in the 50-60 year age group. Estrogen alone appeared to be safer to use than estrogen + the progestin medroxyprogesterone acetate and actually reduced breast cancer. PMID:24176761

    2014-01-01

    Objective It has been forecasted that the rabbiteye blueberry could inhibit osteoporosis. However, the inhibition and prevention of osteoporosis via rabbiteye blueberry are still elusive. This study was aim to evaluate the anti-osteoporosis effects of rabbiteye blueberry in ovariectomized rats. Methods Thirty rats were randomly divided into three groups of ten rats each as follows: sham-operated group (SG), ovariectomized model control group (OMG), and ovariectomized rabbiteye blueberry treatment group (OBG). The blood mineral levels, the alkaline phosphatase (ALP) activity, and osteoprotegerin (OPG) level were determined. The expression analyses of type I collagen, integrin-β1, and focal adhesion kinase (FAK) were performed. Besides, the bone mineral density (BMD) and bone histomorphometry (BH) were measured. Results The ALP activity in SG and OBG was significantly lower than that in OMG. For the OPG level, the significant increase of OPG level in OBG was indicated compared with the other groups. The mRNA expression levels of type I collagen, integrin-β1, and FAK in OMG were significantly lower than those in other groups. The BMD in OMG were all significantly lower than those in SG and OBG. For BH, blueberry significantly improved the trabecular bone volume fraction, trabecular thickness, mean trabecular bone number, and bone formation rate, and decreased the trabecular separation, the percent of bone resorption perimeter, and mean osteoclast number in OBG compared with OMG. Conclusions The rabbiteye blueberries had an effective inhibition in bone resorption, bone loss, and reduction of bone strength of ovariectomized rats and could improve the BMD, osteogenic activity, and trabecular bone structure.

    Particle induced X-ray emission (PIXE) and nuclear microprobe (NMP) have been used in an exploratory work to study elemental alterations in tissues of experimental animals submitted to osteoporosis preventive treatments. Osteopathologies have been associated with several factors, such as hormonal disturbances, metabolic aberrations, low dietary Ca and vitamin D intake, excess of iron, among other possible factors. Hormonal treatments seem to be beneficial to the incorporation of Ca in bone but breast and endometrial cancers constitute significant side effects that cannot be ignored. Wistar female rats were used to test the effect of estrogen therapy in osteoporosis progression. The variations of elemental concentrations in uterus and the Ca content of femoral bones of ovariectomised rats under estrogen therapy were investigated. PIXE, Rutherford backscattering spectrometry and secondary electron microscopy techniques were applied for the characterisation of biological materials, with respect to morphology and trace element distribution determination. The increase of Ca and Fe concentrations in uterus and the variations for Ca distribution patterns in bone of rats submitted to estrogen therapy were the major features observed.

    2015-01-01

    Osteoporosis is a systemic skeletal disorder characterized by bone loss, which leads to impaired bone strength and an increased risk of fractures. Two million fractures are attributed to osteoporosis annually in the United States and they are associated with serious morbidity and mortality. Bisphosphonates reduce the risk of fracture by suppressing bone resorption and increasing bone strength, and they have been widely used for the prevention and treatment of osteoporosis. However, the use of these drugs for the management of osteoporosis remains a clinical challenge. There are several important considerations including appropriate patient selection, pretreatment evaluation, potential adverse effects, patient preferences, and adherence. This review will discuss the evidence informing the clinical strategy for using bisphosphonates in patients with osteoporosis and those at high risk of fracture, focusing on the benefits and risks of treatment. We will also consider issues related to the monitoring and duration of treatment. PMID:26333528

    Osteoporosis is a chronic disease, carrying an elevated risk of fractures, morbidity, and death. Long-term treatment may be required, but the long-term risks with osteoporosis drugs remain incompletely understood. The competing risk of death may be a barrier to treating the oldest, yet this may not be rational if the risk of death is reduced by treatment. It is difficult to devise goal-directed long-term strategies for managing osteoporosis without firm information about residual life expectancy in treated patients. We conducted an observational study in Danish national registries tracking prescriptions for osteoporosis drugs, comorbid conditions, and deaths. We included 58,637 patients and 225,084 age- and sex-matched control subjects. Information on deaths until the end of 2013 was retrieved, providing a follow-up period of 10 to 17 years. In men younger than 80 years and women younger than 60 years, the relative risk of dying declined from being strongly increased in the first year to a stable but elevated level in subsequent years. In women older than 65 to 70 years, there was only a small elevation in risk in the first year of treatment followed by lower than background population mortality. The residual life expectancy of a 50-year-old man beginning osteoporosis treatment was estimated to be 18.2 years and that of a 75-year-old man was 7.5 years. Estimates in women were 26.4 years and 13.5 years, respectively. This study shows an excess mortality in men and in women younger than 70 years who are treated for osteoporosis compared with the background population. This excess risk is more pronounced in the first few years on treatment. The average life expectancy of osteoporosis patients is in excess of 15 years in women younger than 75 years and in men younger than 60 years, highlighting the importance of developing tools for long-term management.

    Introduction Osteoporosis is an illness characterized by the handicapped endurance of the bones, causing an increased risk of fracture. Aim of the study Aim of the study was to establish the level of knowledge about osteoporosis prevention among women screened by bone densitometry and to answer the question whether the level of knowledge is dependent on socio-demographic factors. Material and methods The research was realized by means of a survey method, a poll technique in 2014. The study involved 292 women aged 51-83. The examined women were patients undergoing bone densitometry in the healthcare centres in Lublin. The osteoporosis knowledge test (OKT, revised 2011) by Phyllis Gendler was used as a research tool. Gathered material was subject to descriptive and statistical analysis. Tukey's test, t-Student test and variance analysis (ANOVA) were all applied. A statistical significance level was set at α = 0.05. Results and conclusions Respondents presented the basic exercise knowledge (M = 9.97) and low knowledge concerning risk factors, screening and treatment of osteoporosis (M = 7.87). The calcium knowledge remained on an average level (M = 14.03). Better educated women, city inhabitants as well as women having very good or good social and welfare conditions showed a significantly higher level of knowledge about osteoporosis prevention. Even women undergoing bone densitometry examination present insufficient knowledge about osteoporosis prevention. PMID:27582684

    Osteoporosis poses a significant public health issue. National Societies have developed Guidelines for the diagnosis and treatment of this disorder with an effort of adapting specific tools for risk assessment on the peculiar characteristics of a given population. The Italian Society for Osteoporosis, Mineral Metabolism and Bone Diseases (SIOMMMS) has recently revised the previously published Guidelines on the diagnosis, riskassessment, prevention and management of primary and secondary osteoporosis. The guidelines were first drafted by a working group and then approved by the board of SIOMMMS. Subsequently they received also the endorsement of other major Scientific Societies that deal with bone metabolic disease. These recommendations are based on systematic reviews of the best available evidence and explicit consideration of cost effectiveness. When minimal evidence is available, recommendations are based on leading experts' experience and opinion, and on good clinical practice. The osteoporosis prevention should be based on the elimination of specific risk factors. The use of drugs registered for the treatment of osteoporosis are recommended when the benefits overcome the risk, and this is the case only when the risk of fracture is rather high as measured with variables susceptible to pharmacological effect. DeFRA (FRAX® derived fracture risk assessment) is recognized as a useful tool for easily estimate the long-term fracture risk. Several secondary forms of osteoporosis require a specific diagnostic and therapeutic management. PMID:27339372

  1. Hormone replacement therapy and the prevention of postmenopausal osteoporosis

    2014-01-01

    Fracture prevention is one of the public health priorities worldwide. Estrogen deficiency is the major factor in the pathogenesis of postmenopausal osteoporosis, the most common metabolic bone disease. Different effective treatments for osteoporosis are available. Hormone replacement therapy (HRT) at different doses rapidly normalizes turnover, preserves bone mineral density (BMD) at all skeletal sites, leading to a significant, reduction in vertebral and non-vertebral fractures. Tibolone, a selective tissue estrogenic activity regulator (STEAR), is effective in the treatment of vasomotor symptoms, vaginal atrophy and prevention/treatment of osteoporosis with a clinical efficacy similar to that of conventional HRT. Selective estrogen receptor modulators (SERMs) such as raloxifene and bazedoxifene reduce turnover and maintain or increase vertebral and femoral BMD and reduce the risk of osteoporotic fractures. The combination of bazedoxifene and conjugated estrogens, defined as tissue selective estrogen complex (TSEC), is able to reduce climacteric symptoms, reduce bone turnover and preserve BMD. In conclusion, osteoporosis prevention can actually be considered as a major additional benefit in climacteric women who use HRT for treatment of climacteric symptoms. The use of a standard dose of HRT for osteoporosis prevention is based on biology, epidemiology, animal and preclinical data, observational studies and randomized, clinical trials. The antifracture effect of a lower dose HRT or TSEC is supported by the data on BMD and turnover, with compelling scientific evidence. PMID:26327857

    2009-02-01

    Osteoporosis is a major health issue worldwide, with significant economic consequences and adverse impacts on the quality of life. Hip fractures are the most devastating complication of osteoporosis, are likely to increase exponentially with an increasingly aged population, are associated with high recurrence rate, and lead to significant morbidity and mortality. This review discusses the prevalence and impact of hip fractures, the assessment of fracture risk, fall prevention, and treatment of osteoporosis with emphasis on evidence for hip fracture reduction among the various agents currently available. The aim is to provide recommendations to optimize hip fracture prevention and treatment. Ample evidence exists in the literature of many other risk factors independent from bone mineral density that increase fracture risk. These clinical risk factors have been validated in large cohorts and are incorporated into clinical tools that are invaluable in treatment decisions. In addition, strategies to prevent or reduce falls are integral to comprehensive osteoporosis management. Vitamin D combined with calcium has a role in primary prevention. Alendronate, residronate, strontium and zoledronic acid have proven efficacy in primary and secondary hip fracture prevention. An aggressive approach to investigate, assess and manage an individual's fracture risk and fall risk is paramount to reduce the high morbidity and mortality associated with hip fractures. The choice of therapy should be determined by the patient's calculated fracture risk and efficacy of the potential treatment, including long term compliance associated with the agent of choice.

    Skeletal degeneration due to aging, also known as osteoporosis, is a major health problem worldwide. Certain dietary components confer protection to our skeletal system against osteoporosis. Consumption of olives, olive oil and olive polyphenols has been shown to improve bone health. This review aims to summarize the current evidence from cellular, animal and human studies on the skeletal protective effects of olives, olive oil and olive polyphenols. Animal studies showed that supplementation of olives, olive oil or olive polyphenols could improve skeletal health assessed via bone mineral density, bone biomechanical strength and bone turnover markers in ovariectomized rats, especially those with inflammation. The beneficial effects of olive oil and olive polyphenols could be attributed to their ability to reduce oxidative stress and inflammation. However, variations in the bone protective, antioxidant and anti-inflammatory effects between studies were noted. Cellular studies demonstrated that olive polyphenols enhanced proliferation of pre-osteoblasts, differentiation of osteoblasts and decreased the formation of osteoclast-like cells. However, the exact molecular pathways for its bone health promoting effects are yet to be clearly elucidated. Human studies revealed that daily consumption of olive oil could prevent the decline in bone mineral density and improve bone turnover markers. As a conclusion, olives, olive oil and its polyphenols are potential dietary interventions to prevent osteoporosis among the elderly. PMID:27472350

    2011-12-01

    Evidence from both epidemiological studies and basic research suggests that obesity and osteoporosis are interrelated. Though there is an increase in the prevalence of these disorders, a limited number of treatments are available, one of the reasons being the complexity of the pathways involved and difficulty in identifying a single molecular target. Due to adverse effects of pharmaceuticals, intake of herbal drugs by patients without a physician's recommendation is increasing globally. Lack of success with targeted monotherapy has encouraged scientists to determine whether combinations of phytochemicals that interfere with numerous cell-signaling pathways can be a more effective approach to treat complex diseases. For example, evidence is emerging that specific combinations of phytochemicals are far more effective than single compounds in decreasing adipogenesis and promoting bone formation. Since multiple pathways are dysfunctional in obesity and osteoporosis, an ideal approach for preventing and treating these diseases may be to use a combination of phytochemicals to address several targets simultaneously.

    In this paper the most significant biological and clinical aspects of a biopreparation made of chicken eggshells are reviewed. Eggshell powder is a natural source of calcium and other elements (e.g. strontium and fluorine) which may have a positive effect on bone metabolism. Experimental and clinical studies performed to date have shown a number of positive properties of eggshell powder, such as antirachitic effects in rats and humans. A positive effect was observed on bone density in animal models of postmenopausal osteoporosis in ovariectomized female rats. In vitro eggshell powder stimulates chondrocyte differentiation and cartilage growth. Clinical studies in postmenopausal women and women with senile osteoporosis showed that eggshell powder reduces pain and osteoresorption and increases mobility and bone density or arrests its loss. The bioavailability of calcium from this source, as tested in piglets, was similar or better than that of food grade purified calcium carbonate. Clinical and experimental studies showed that eggshell powder has positive effects on bone and cartilage and that it is suitable in the prevention and treatment of osteoporosis. PMID:15018022

    Bone events related to bariatric surgery remain controversial. Denosumab, used in osteoporosis treatment, is safe and efficient. Romosozumab, an antibody raised against sclerostin, is a promising bone anabolic agent. Odanacatib, a cathepsin-K inhibitor, decreases bone resorption and reduces osteoporotic fracture risk. Denosumab, as bone resorption inhibitor, and Teriparatide, as anabolic agent, have been tested together in patients with osteoporosis. Calcium supplements and cardiovascular risk are still debated. Drug holiday, after long-term treatment with bisphosphonates, is not associated with an increased fracture rate in patients with moderate risk. PMID:25799662

    PubMed

    Reid, Ian R

    2014-02-01

    Advocacy for the use of calcium supplements arose at a time when there were no other effective interventions for the prevention of osteoporosis. Their promotion was based on the belief that increasing calcium intake would increase bone formation. Our current understandings of the biology of bone suggest that this does not occur, though calcium does act as a weak antiresorptive. Thus, it slows postmenopausal bone loss but, despite this, recent meta-analyses suggest no significant prevention of fractures. In sum, there is little substantive evidence of benefit to bone health from the use of calcium supplements. Against this needs to be balanced the likelihood that calcium supplement use increases cardiovascular events, kidney stones, gastrointestinal symptoms, and admissions to hospital with acute gastrointestinal problems. Thus, the balance of risk and benefit seems to be consistently negative. As a result, current recommendations are to obtain calcium from the diet in preference to supplements. Dietary calcium intake has not been associated with the adverse effects associated with supplements, probably because calcium is provided in smaller boluses, which are absorbed more slowly since they come together with quantities of protein and fat, resulting in a slower gastric transit time. These findings suggest that calcium supplements have little role to play in the modern therapeutics of osteoporosis, which is based around the targeting of safe and effective anti-resorptive drugs to individuals demonstrated to be at increased risk of future fractures.

    Osteoporosis is among the main causes for bone fractures. In this overview we report on the prevalence of the disease, the diagnostic procedures, and the therapeutic options. The prevalence increases with age and women are more often affected than men. The diagnosis usually is made on the basis of dual X-ray absorptiometry. Prophylactic measures include a sufficient intake of calcium and vitamin D. Bisphosphonates play a central role in the pharmacotherapy of this disease. PMID:27439255

    Osteoporosis in elderly men is now becoming an alarming health issue due to its relation with a higher mortality rate compared to osteoporosis in women. Androgen deficiency (hypogonadism) is one of the major factors of male osteoporosis and it can be treated with testosterone replacement therapy (TRT). However, one medicinal plant, Eurycoma longifolia Jack (EL), can be used as an alternative treatment to prevent and treat male osteoporosis without causing the side effects associated with TRT. EL exerts proandrogenic effects that enhance testosterone level, as well as stimulate osteoblast proliferation and osteoclast apoptosis. This will maintain bone remodelling activity and reduce bone loss. Phytochemical components of EL may also prevent osteoporosis via its antioxidative property. Hence, EL has the potential as a complementary treatment for male osteoporosis. PMID:22844328

    It is well known that people, especially white people, are getting osteoporosis more often than previously thought. Until now, no direct causative factor has been determined, but genetic factors are very likely to be involved. Usually, affected individuals are initially asymptomatic while the disease process is going on, and they come to the attention of the medical profession only late when their bones are fractured as a result of a simple trauma. Also it is vital to let people know that heavy sports, at times, can be harmful. PMID:15339135

    Postmenopausal women have high incidence of cardiovascular events as estrogen deficiency can cause endothelial dysfunction. Vitamin D is reported to be beneficial on endothelial function, but it remains controversial whether vitamin D is effective for endothelial dysfunction under the treatment for osteoporosis in postmenopausal women. The aim of this study was to evaluate the endothelial protective effect of eldecalcitol (ELD) in ovariectomized (OVX) rats. ELD (20  ng/kg) was orally administrated five times a week for 4 weeks from 1 day after surgery. After that, flow-mediated dilation (FMD) as an indicator of endothelial function was measured by high-resolution ultrasound in the femoral artery of living rats. ELD ameliorated the reduction of FMD in OVX rats. ELD inhibited the increase in NOX4, nitrotyrosine, and p65 and the decrease in dimer/monomer ratio of nitric oxide synthase in OVX rat femoral arteries. ELD also prevented the decrease in peroxisome proliferator-activated receptor gamma (PPARγ) in femoral arteries and cultured endothelial cells. Although PPARγ is known to inhibit osteoblastogenesis, ELD understandably increased bone mineral density of OVX rats without increase in PPARγ in bone marrow. These results suggest that ELD prevented the deterioration of endothelial function under condition of preventing bone loss in OVX rats. This endothelial protective effect of ELD might be exerted through improvement of endothelial nitric oxide synthase uncoupling, which is mediated by an antioxidative effect through normalization of vascular PPARγ/NF-κB signaling.

    Estrogen replacement therapy (ERT) is the main treatment postmenopausal osteoporosis. However, ERT causes serious side effects, such as cancers and thromboembolic problems. Labisia pumila var. alata (LPva) is a herb with potential as an alternative to ERT to prevent complications of osteoporosis, especially fragility fractures. This study was conducted to determine the effects of LPva on the biomechanical strength of femora exposed to osteoporosis due to estrogen deficiency, using the postmenopausal rat model. Thirty-two female rats were randomly divided into four groups: Sham-operated (Sham), ovariectomized control (OVXC), ovariectomized with Labisia pumila var. alata (LP), and ovariectomized with ERT (Premarin) (ERT). The LPva and ERT were administered via oral gavage daily at doses of 17.5 mg/kg and 64.5 μg/kg, respectively. Following two months of treatment, the rats were euthanized, and their right femora were prepared for bone biomechanical testing. The results showed that ovariectomy compromised the femoral strength, while LPva supplementation to the ovariectomized rats improved the femoral strength. Therefore, LPva may be as effective as ERT in preventing fractures due to estrogen-deficient osteoporosis. PMID:22991574

    Osteoporosis is a mechanical incompetence of bone which finally leads to fracture. The occurrence of a fracture for a minor trauma is the definitive evidence of bone fragility and an indication of an higher probability for other fractures. Fracture at any site is a strong risk factor for a subsequent fracture, therefore any patient with a prevalent fracture is an ideal candidate for treatment due to the high risk for recurrence and to a favourable cost-benefit ratio. Most of the available pharmacological agents approved for osteoporosis treatment are effective in reducing fracture risk in this class of patients. Unfortunately, poor compliance is very common in patients treated for osteoporosis and this leads to reduced benefits and ineffectual costs. Dose regimen simplification is neither the only nor the most important solution to improve compliance, and a multifaceted strategy targeting cognitive, behavioural and emotional factors should be employed.

    Calcium intake has a role on the development of peak bone mass, and has a mild impact on the maintenance of bone mass during adulthood and the reduction of bone loss rate in postmenopausal women and the elderly in both genders. Calcium dietary intake should be privileged over supplementation. Dairy products are the main calcium dietary sources. Prospective studies have not clearly demonstrated an effect on the prevention of fractures, because of the practical difficulties of a long follow-up in order to get to solid conclusions; however the physiological rationale is that an adequate calcium intake and 25(OH) vitamin D levels exceeding 20 ng/ml is beneficial for bone health and may decrease to certain extent the risk of fractures.

Women belong to the increased osteoporosis illness risk group due to lower top bone mass reached earlier in life as compared to men and due to hormonal changes occurring in the menopausal period, which affect loss of the bone mineral density (BMD). Limitation of the osteoporosis-related financial and social costs increase requires efficient preventive actions on the level of early, primary, secondary or tertiary prevention. At all the four osteoporosis prevention phases, the crucial role is played by health education and nutrition education, the latter being the key element of the former one. The nutritional education purpose is to acquaint patients with nutrition recommendations that are the basic element of the osteoporosis prevention and to make them change their nutrition habits, which will improve their osseous metabolism. The education should be based on results of the latest scientific researches and focus on recommendations relating to proper supplementing of calcium and vitamin D, simultaneously including all the other nutrition components, necessary to decrease the osteoporosis risk. The primary prevention oriented to a specific group at risk for osteoporosis, including peri- or postmenopausal women, should be provided in cooperation with the different levels' medical professionals and it should focus on causing positive changes in patients both as regards nutrition habits and physical activities.

    Osteoporosis imposes a tremendous burden on Australia: 1.2 million Australians have osteoporosis and 6.3 million have osteopenia. In the 2007–08 financial year, 82 000 Australians suffered fragility fractures, of which > 17 000 were hip fractures. In the 2000–01 financial year, direct costs were estimated at $1.9 billion per year and an additional $5.6 billion on indirect costs. Osteoporosis was designated a National Health Priority Area in 2002; however, implementation of national plans has not yet matched the rhetoric in terms of urgency. Building healthy bones throughout life, the Osteoporosis Australia strategy to prevent osteoporosis throughout the life cycle, presents an evidence-informed set of recommendations for consumers, health care professionals and policymakers. The strategy was adopted by consensus at the Osteoporosis Australia Summit in Sydney, 20 October 2011. Primary objectives throughout the life cycle are: to maximise peak bone mass during childhood and adolescence to prevent premature bone loss and improve or maintain muscle mass, strength and functional capacity in healthy adults to prevent and treat osteoporosis in order to minimise the risk of suffering fragility fractures, and reduce falls risk, in older people. The recommendations focus on three affordable and important interventions — to ensure people have adequate calcium intake, vitamin D levels and appropriate physical activity throughout their lives. Recommendations relevant to all stages of life include: daily dietary calcium intakes should be consistent with Australian and New Zealand guidelines serum levels of vitamin D in the general population should be above 50nmol/L in winter or early spring for optimal bone health regular weight-bearing physical activity, muscle strengthening exercises and challenging balance/mobility activities should be conducted in a safe environment.

    Medical complications such as renal stone formation, increased uric acid output, and disuse osteoporosis are discussed. A series of experiments was conducted in order to study and eventually reduce these flight hazards. Attempts to prevent the negative calcium balance and loss of calcaneal density during prolonged bed rest had only a limited success. Of the five biochemical regiments tested, only diphosphonate applied in a high dose had a positive effect in elliminating mineral losses. It is found that clodronate can prevent disuse osteoporosis and that fluoride can enhance bone formation. It is concluded that exercises, combined with pharmaceutical agents, are beneficial during long-duration space missions.

    The hibernating bear is an excellent model for disuse osteoporosis in humans because it is a naturally occurring large animal model. Furthermore, bears and humans have similar lower limb skeletal morphology, and bears walk plantigrade like humans. Black bears (Ursus americanus) may not develop disuse osteoporosis during long periods of disuse (i.e. hibernation) because they maintain osteoblastic bone formation during hibernation. As a consequence, bone volume, mineral content, porosity, and strength are not adversely affected by annual periods of disuse. In fact, cortical bone bending strength has been shown to increase with age in hibernating black bears without a significant change in porosity. Other animals require remobilization periods 2-3 times longer than the immobilization period to recover the bone lost during disuse. Our findings support the hypothesis that black bears, which hibernate for as long as 5-7 months annually, have evolved biological mechanisms to mitigate the adverse effects of disuse on bone porosity and strength. ?? 2005 Elsevier Ltd.

    Background Little information is available on the comparative effectiveness of osteoporosis pharmacotherapies. Objective To compare the relative effectiveness of osteoporosis treatments to reduce nonvertebral fracture risk among older adults. Design Cohort study. Setting Enrollees in 2 statewide pharmaceutical benefit programs for persons age 65 years or older. Patients 43 135 new recipients of oral bisphosphonates, nasal calcitonin, and raloxifene who began treatment from 2000 to 2005. The mean age was 79 years (SD, 6.9), and 96% were women. Measurements The primary outcome was nonvertebral fracture (hip, humerus, or radius or ulna) within 12 months of treatment initiation. Cox proportional hazard models stratified by state and adjusted for risk factors for fracture were used to compare fracture rates. Alendronate was the reference category in all analyses. Results A total of 1051 nonvertebral fractures were observed within 12 months (2.62 fractures per 100 person-years). No large differences in fracture risk were found between risedronate (hazard ratio [HR], 1.01 [95% CI, 0.85 to 1.21]) or raloxifene (HR, 1.18 [CI, 0.96 to 1.46]) and alendronate. However, among those with a fracture history, raloxifene recipients experienced more nonvertebral fractures within 12 months (HR, 1.78 [CI, 1.20 to 2.63]) compared with alendronate recipients. Patients who received calcitonin experienced more nonvertebral fractures than those who received alendronate (HR, 1.40, [CI, 1.20 to 1.63]). Results were similar in sensitivity analyses that examined different lengths of follow-up (6 months and 24 months), were restricted to hip fracture as the outcome, and were completed in various subgroups. Limitation Confounder adjustment was limited to health care utilization data, and the confidence bounds of some comparisons were too wide to rule out potential clinically important differences between agents.

    Objectives To develop and validate Osteoporosis Prevention and Awareness Tool (OPAAT) in Malaysia. Methods The OPAAT was modified from the Malaysian Osteoporosis Knowledge Tool and developed from an exploratory study on patients. Face and content validity was established by an expert panel. The OPAAT consists of 30 items, categorized into three domains. A higher score indicates higher knowledge level. English speaking non-osteoporotic postmenopausal women ≥50 years of age and pharmacists were included in the study. Results A total of 203 patients and 31 pharmacists were recruited. Factor analysis extracted three domains. Flesch reading ease was 59.2. The mean±SD accuracy rate was 0.60±0.22 (range: 0.26-0.94). The Cronbach’s α for each domain ranged from 0.286-0.748. All items were highly correlated (Spearman’s rho: 0.761-0.990, p<0.05), with no significant change in the overall test-retest scores, indicating that OPAAT has achieved stable reliability. Pharmacists had higher knowledge score than patients (80.9±8.7vs63.6±17.4, p<0.001), indicating that the OPAAT was able to discriminate between the knowledge levels of pharmacists and patients. Conclusion The OPAAT was found to be a valid and reliable instrument for assessing patient’s knowledge about osteoporosis and its prevention in Malaysia. The OPAAT can be used to identify individuals in need of osteoporosis educational intervention. PMID:25938494

    Background As silent and preventable in nature, postmenopausal osteoporosis awareness should be raised among young women prior to an irreversible period of declining bone mass. We therefore decided to assess the inter-correlation of knowledge, attitude and osteoporosis preventive behaviors in women around the age of peak bone mass. Methods A cross-sectional study was conducted in 430 women aged 20–35 years. The participants’ knowledge, attitude and behaviors concerning osteoporosis prevention were assessed along with demographic data using a four-part questionnaire. The items in this questionnaire were established by extensive literature review, including the Guideline for Management of Osteoporosis of the Thai Osteoporosis Foundation (TOPF) 2010. The content was validated by experts in osteoporosis and reliability was obtained with a Cronbach’s alpha score of 0.83. Results The mean age of women in this study was 29.4 ± 4.6 years. Half of the participants (49.5%) had heard about osteoporosis, mostly from television (95.3%, n = 203/213) and the internet (72.8%, n = 155/213). Most women had certain knowledge (85.2%) and positive attitude towards osteoporosis (53.3%). Nevertheless, 80% of the studied population did not have appropriate osteoporosis behaviors. We found significant correlation between the level of attitudes and osteoporosis behaviors (adjusted odd ratio = 3.3 with 95% confidence interval of 1.9-5.7); attitude and educational level (adjusted odd ratio = 2.2 with 95% confidence interval of 1.4-3.4); and attitude and knowledge (adjusted odd ratio = 3.5 with 95% confidence interval of 1.8-6.8). Conclusion Despite having certain knowledge about osteoporosis, the young women did not seem to have appropriate osteoporosis preventive behaviors. Developing a right attitude towards osteoporosis may be a key determinant to improving health practices in order to prevent osteoporosis. PMID:24588970

    Phytate-removed and deamidated soybean β-conglycinin (PrDS) prepared by ion-exchange resins was supplemented to be 4% in the diet administered to ovariectomized rats to investigate its preventive effect on osteoporosis. The apparent calcium absorption rate decreased following ovariectomy and was not replenished by oral administration of phytate-removed soybean β-conglycinin (PrS) or casein. On the other hand, administration of PrDS restored the calcium absorption rate to the same level as the sham group. Markers of bone resorption, such as serum parathyroid hormone (PTH) and urinary deoxypyridinoline (DPD), increased, and the bone mineral density and breaking stress decreased following ovariectomy. However, PrDS supplementation suppressed the changes caused by the decrease in calcium absorption from the small intestine. Therefore, PrDS supplementation shows promise for the prevention of postmenopausal osteoporosis. PMID:25607735

    Oxidative stress and free radicals have been implicated in the pathogenesis of osteoporosis. Therefore, antioxidant compounds have the potential to be used in the prevention and treatment of the disease. In this study, we investigated the effects of virgin coconut oil (VCO) on bone microarchitecture in a postmenopausal osteoporosis rat model. VCO is a different form of coconut oil as it is rich with antioxidants. Three-month-old female rats were randomly grouped into baseline, sham-operated, ovariectomized control (Ovx), and ovariectomized rats fed with 8% VCO in their diet for six weeks (Ovx+VCO). Bone histomorphometry of the right femora was carried out at the end of the study. Rats supplemented with VCO had a significantly greater bone volume and trabecular number while trabecular separation was lower than the Ovx group. In conclusion, VCO was effective in maintaining bone structure and preventing bone loss in estrogen-deficient rat model. PMID:23024690

    Chan, Valerie; Cave, Andrew J

    2015-01-01

    Objectives: The use of inhaled corticosteroids is the standard maintenance therapy in asthma therapy and as adjunct therapy in moderate to severe chronic obstructive pulmonary disease. A dose-related increase in fracture risk is associated with inhaled corticosteroid use; there is an inverse relationship between bone mineral density and duration and cumulative dose of inhaled corticosteroid. Adequate intake of calcium and vitamin D are cornerstones of osteoporosis prevention. The objectives are to assess whether the proportion of patients receiving inhaled corticosteroids are taking calcium and vitamin D; the association between long-term inhaled corticosteroid use and abnormal bone mineral density or fractures; and how many qualified patients received bone mineral density scans. Methods: Patients who filled a prescription for inhaled corticosteroids at selected community pharmacies across Alberta were recruited for a survey of their osteoporosis prevention activities. Results: A total of 256 patients from 12 community pharmacies were included. The average age was 60 ± 17.4 years with 65% female. There were 21%, 51%, and 28% of patients on high, medium, and low dose inhaled corticosteroids, respectively. Only 17% of patients >50 years old received recommended calcium and vitamin D supplementation and 87 (73%) of the qualified patients received bone mineral density scan. Conclusion: Osteoporosis prevention in inhaled corticosteroid users is currently poorly addressed. More promotion is needed to raise pharmacist awareness of the risks of inhaled corticosteroids.

    Clinical practice guidelines should be written for the physician who sees patients who already have or are at high risk for osteoporosis. They should also guide the physician in distinguishing between those at high and low risk and provide general guidelines for prevention of osteoporosis for the low-risk patient. Patients at high risk may require intervention to prevent further bone loss. The guidelines should be based on the strongest evidence available and be easy to comprehend and apply. Methods to identify individuals at high risk for osteoporosis must be described. Effective interventions also should be described, as should their benefits and risks. Elderly individuals who have a poor diet and little sun exposure may be vitamin D deficient unless a supplement is given. Factors that may be deleterious to the skeleton should be avoided. Weight-bearing exercise is important throughout life. Assessment of fracture risk is important in choosing candidates for intervention, especially interventions aimed at preventing osteoporosis. Measuring bone mass at any skeletal site is the necessary initial step for most individuals; measurement at the hip may best assess the risk of hip fracture. Some risk factors independent of bone mass may also aid in patient selection. The WHO has defined osteoporosis as a bone mass at least 2.5 standard deviations (SDs) below the mean of young normal. Such individuals and those with bone mass from 1 to 2.5 SDs below the mean of young normal may also be considered for intervention. The decision will depend on assessments of the risks, the costs of treatment, the desire of the patient, and the presence of other independent risk factors. The patient with an acute fracture may require an orthopedic intervention and should receive adequate analgesia. Physical therapy is an important adjunct that aids recovery. A number of therapeutic interventions, including adequate calcium intake throughout life and an adequate vitamin D intake, are

    The purpose of this study was to investigate the therapeutic effects of crocin on ovariectomy-induced osteoporosis in rats. Female Sprague-Dawley rats were randomly assigned to a sham-operated group (sham) and five ovariectomy (OVX) subgroups, that is, OVX with vehicle (OVX), OVX with 17β-estradiol (E2, 25 μg/kg/day), and OVX with graded crocin doses (5, 10, or 20 mg/kg/day). Daily oral administration of E2 or crocin started 4 weeks after OVX and lasted for 16 weeks. Our results showed that crocin dose-dependently inhibited the BMD reduction of L4 vertebrae and femurs caused by OVX and prevented the deterioration of trabecular microarchitecture, which were accompanied by a significant decrease in skeletal remodeling as evidenced by the lower levels of bone turnover markers. Furthermore, crocin reversed the oxidative stress status in both serum and bone tissue. The present study indicates that the administration of crocin at higher doses over a 16-week period can prevent OVX-induced osteoporosis in rats without hyperplastic effects on the uterus, which may, at least partially, be attributed to crocin's antioxidative property. In brief, crocin is a natural alternative for postmenopausal osteoporosis treatment in elderly women. PMID:25202337

    Currently, there are several treatments for osteoporosis however; they all display some sort of limitation and/or side effects making the need for new treatments imperative. We have previously demonstrated that NMP is a bioactive drug which enhances bone regeneration in vivo and acts as an enhancer of bone morphogenetic protein (BMP) in vitro. NMP also inhibits osteoclast differentiation and attenuates bone resorption. In the present study, we tested NMP as a bromodomain inhibitor and for osteoporosis prevention on ovariectomized (OVX) induced rats while treated systemically with NMP. Female Sprague-Dawley rats were ovariectomized and weekly NMP treatment was administrated 1 week after surgery for 15 weeks. Bone parameters and related serum biomarkers were analyzed. 15 weeks of NMP treatment decreased ovariectomy-induced gained weight in average by 43% and improved bone mineral density (BMD) and bone volume over total volume (BV/TV) in rat femur on average by 25% and 41% respectively. Moreover, mineral apposition rate and bone biomarkers of bone turnover in the treatment group were at similar levels with those of the Sham group. Due to the function of NMP as a low affinity bromodomain inhibitor and its mechanism of action involving osteoblasts/osteoclasts balance and inhibitory effect on inflammatory cytokines, NMP is a promising therapeutic compound for the prevention of osteoporosis.

    Production and evaluation of different diet formulas fortified with oyster shell for the prevention and treatment of osteoporosis. Eighty-eight female albino rats were recruited and divided into 11 groups (8 rats each). Group 1 represented negative control while the remaining groups were ovariectomized. Group 2 acted as positive control. Groups 3-5 were fed on basal diet. Groups 6-8 were fed on lentil soup while groups 9-11 were fed on vegetable soup. Group 4, 7, 10 were fed on diets fortified with oyster shell. Groups 5, 8 and 11 were fed on diet formulas fortified with calcium citrate. All calcium fortified diet formulas, especially lentil soup, have minimized risk factors associated with osteoporosis as indicated from the significant increase in tibial weight, total protein, total calcium and phosphorus with noticeable reduction in ALP activity compared to positive group. Maximum recovery was observed for diet fortified with oyster shell. These data suggest that food products fortified with oyster shell as natural and inexpensive source could be beneficial for the prevention and treatment of osteoporosis. PMID:26396435

    An attempt was made to modify factors which promote disuse osteoporosis and thereby prevent it from occurring. Since fluoride is currently used to enhance bone formation in the treatment of low turnover osteoporosis, it was hypothesized that if the fluoride ion was available over a long period of time that it would slow the demonstrated loss of calcium by inhibiting bone resorption and enhancing bone formation. This study was used to determine whether oral medication with sodium F will modify or prevent 5 weeks of bed rest induced disuse osteoporosis, to determine the longitudinal effects of 5 weeks of bed rest on PTH, CT and calcitriol, to measure muscle volume changes and metabolic activity by magnetic resonance imaging and magnetic resonance spectroscopy during prolonged bed rest, to measure changes in peak muscle strength and fatigability, and to measure bone turnover in bone biopsies. Subjects were studied during 1 week of equilibration, 4 weeks of control ambulation, 5 weeks of bed rest, and 1 week of reambulation.

    Low bone mass is a major determinant of bone fragility. With respect to hip fracture risk however, there is limited contribution of BMD to the exponential age-related increase in hip fracture incidence. Large prospective studies have identified a number of additional risk factors for hip fractures independent of bone density. These can be classified as skeletal factors and fall-related factors. Body height and hip axis length are positively correlated with fracture risk. Neuromuscular impairment with low gait speed, difficulty in doing a tandem walk, lower limb dysfunction, body sway or inability to rise from a chair without using one's arms predict future fracture risk. According to the concept of evidence-based medicine (EBM) preventive strategies are now available. Supplementation with calcium and vitamin D restores bone quality through suppression of secondary hyperparathyroidism and decreases the risk of falling through improvement of neuromuscular co-ordination and body sway. Treatment with the bisphosphonates alendronate and risedronate increase bone strength and result in a significant reduction of vertebral as well as non-vertebral fractures. Hip protectors absorb energy during a fall and reduce hip fracture risk by 56%. Risk factor based patient selection may improve the cost-effectiveness of therapy. PMID:10996933

    Background: Osteoporosis is the most common metabolic bone disease. The study's objective is to investigate the effect of an educational program based on Health Belief Model (HBM) on preventing osteoporosis in women. Methods: In this quasi-experimental study, 120 patients (60 experimental and 60 control) who were registered under the health centers in Fasa City, Fars Province, Iran, were selected in 2014. A questionnaire consisting of demographic information, HBM constructs was used to measure nutrition and walking performance for the prevention of osteoporosis before, immediately after intervention, and 6 months later. Bone mineral density (BMD) was recorded at the lumbar spine and femur before and 6 months after intervention. Results: The mean age of women participated in the study was 41.75 ± 5.4 years for the experimental group, and 41.77 ± 5.43 years for the control group. The mean body mass index was 22.44 ± 3.30 for the experimental group and 22.27 ± 3.05 for the control group. The average number of women deliveries for the experimental group was 2.57 ± 1.47 and 2.50 ± 1.19 for the control group. There is no significant difference between the two groups in education level (P = 0.771), marital status (P = 0.880), occupation (P = 0.673), breastfeeding (P = 0.769), smoking (P = 0.315), history of osteoporosis in the family (P = 0.378), history of special diseases (P = 0.769), and records of bone densitometry (P = 0.543). Immediately and 6 months after intervention, the experimental group showed a significant increase in the knowledge, perceived susceptibility, perceived severity, perceived benefits, perceived barriers, self-efficacy, internal cues to action, nutrition, and walking performance compared to the control group. Six months after intervention, the value of lumbar spine BMD T-score in the experimental group increased to 0.127, while in the control group it reduced to −0.043. The value of the hip BMD T-score in the intervention group increased

    The objective was to evaluate the preventive and therapeutic effects of the collagen hydrolysate extracted from Sika deer velvet (CSDV) on osteoporosis rats induced by retinoicacid. Histomorphometric indices and serum biochemical parameters were measured in osteoporosis rats treated with/without antler collagen and in sham-operated rats. Our results were as follows: compared with the osteoporosis group, significant elevation in the levels of bone mineral density (BMD), Ca, P and static histomorphometric indexes and biomechanical properties, but reduction in the level of serum alkaline phosphatase (ALP) were observed in antler collagen-treated groups. However, the above function with the collagenase solution velvet material varied with the different doses. In conclusion, the extracted collagen is found to play a role in the prevention and treatment of osteoporosis rats by retinoic acid. PMID:20545204

    summary Osteoporotic fractures are common resulting in increased morbidity and mortality. Exercise can help prevent osteoporosis. It can also benefit patients with osteoporosis, but the exercises must be tailored to the patient. Most Australians should be able to obtain adequate calcium in their diet and vitamin D from the sun. Supplements may be needed in some patients and they are recommended for use with other drugs for osteoporosis. Bisphosphonates, and in some patients denosumab, are first-line drugs for osteoporosis. Raloxifene and strontium ranelate can be considered in patients who cannot take bisphosphonates or denosumab. Teriparatide is reserved for patients with severe osteoporosis and the use of strontium ranelate is declining because of cardiovascular safety concerns. PMID:27340321

    Bu-Shen-Ning-Xin decoction (BSNXD), a traditional Chinese medicine, has been used to prevent and treat age-related diseases such as postmenopausal osteoporosis (PMO) for decades. This study sought to investigate the underlying mechanisms of BSNXD in terms of receptor activation of nuclear factor κB ligand (RANKL)-induced osteoclastogenesis in vitro because of the critical roles of bone resorption in the development and progression of osteoporosis. In mice, serum levels of dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEAS), and 17-β-estradiol (E2) were evaluated with an enzyme immunoassay kit after ovariectomy. Levels of DHEA and DHEAS increased significantly following administration of BSNXD while the level of E2 did not. In addition, tartrate-resistance acid phosphatase staining showed that DHEA profoundly inhibited RANKL-induced osteoclastogenesis in vitro in a dose-dependent manner via estrogen receptor α (ERα) but not via estrogen receptor β or androgen receptors. Cytotoxicity was not detected in the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. These data suggest that BSNXD prevents PMO by increasing DHEA via the ERαpathway to suppress osteoclastogenesis. PMID:26166370

    Glucocorticoid-induced osteoporosis (GIO) is the most common type of secondary osteoporosis. The aim of this study was to compare the efficacy of quercetin, a plant-derived flavonoid, with alendronate in the prevention of GIO. Fifty-six Sprague-Dawley rats were randomly distributed among 7 groups (8 rats per group) and treated for 6 weeks with one of the following: (i) normal saline; (ii) 40 mg methylprednisolone sodium succinate (MP)/kg body mass; (iii) MP + 40 μg alendronate/kg; (iv) MP + 50 mg quercetin/kg; (v) MP + 40 μg alendronate/kg + 50 mg quercetin/kg; (vi) MP + 150 mg quercetin/kg; and (vii) MP + 40 μg alendronate/kg + 150 mg quercetin/kg. MP and alendronate were injected subcutaneously and quercetin was administered by oral gavage 3 days a week. At the end of the study, femur breaking strength was significantly decreased as a consequence of MP injection. This decrease was completely compensated for in groups receiving 50 mg quercetin/kg plus alendronate, and 150 mg quercetin/kg with or without alendronate. Quercetin noticeably elevated osteocalcin as a bone formation marker, while alendronate did not show such an effect. In addition, administration of 150 mg quercetin/kg increased femoral trabecular and cortical thickness by 36% and 22%, respectively, compared with the MP-treated group. These data suggest that 150 mg quercetin/kg, alone or in combination with alendronate, can completely prevent GIO through its bone formation stimulatory effect. PMID:23656499

    Objective: The aim of the study was to assess the diet for its effect on normal bone mineralization and qualitative analysis of dietary supplements used in the prevention of osteoporosis. Methods: Research data were acquired based on a questionnaire developed by the author. A 24-hour diet recall method was used with the involvement of Dieta 5.0 software developed by the National Food and Nutrition Institute in Warsaw in Poland. The second part of the study involved an analysis of the most popular dietary supplements available over the counter. Complexometric titration was used to separate and identify calcium. Results: The results of a 24-hour diet recall indicate that 47% of the respondents consumed 550-750 mg of calcium daily, and only 21% of the subjects consumed more than 1200 mg of calcium every day. The results give cause for concern: none of the analyzed diets supplied the recommended daily amounts of vitamin D, and only 29% of the respondents admitted taking vitamin D supplements. The results of the survey indicate that consumers have insufficient knowledge about lifestyle diseases, including osteoporosis. Conclusion: Diet of large part of society is not properly balanced which can cause abnormalities in achieving proper bone mineralization. Long-term deficiencies in calcium and vitamin D in daily diet are the cause for taking dietary supplements. Unfortunately, some preparations on the market do not have adequate storage. It happens that these preparations are poorly absorbed and the amount of active compound is too low. Changes in the nutritional regimen are required already during childhood because nutritional mistakes are the main cause of diet-related diseases in adulthood. PMID:25097513

    production of Th2 helper cells which produce bone protective cytokines like IL-4 and IL-10. It is important to know that D-hormone protects osteoblasts against TNF-alpha-induced cell death. After conversion to D-hormone in the liver and bone, alfacalcidol antagonises the above described pathogenetic factors of the corticosteroids. D-hormone is one of the body's own immunoregulators, which is produced in macrophages in cases of need to reduce immunological overreactions in a feed-back loop. Improved understanding of the pathogenesis of corticosteroid-induced osteoporosis and of the pharmacological effects of alfacalcidol in this type of iatrogenic bone loss as well as the results of specific animal models simulating bone loss in inflammatory diseases explain the favourable effects of alfacalcidol in this indication. Various clinical studies have demonstrated clearly that alfacalcidol retards corticosteroid-induced bone loss in contrast to plain vitamin D. Due to its immunomodulating properties, alfacalcidol is particularly suitable for RA-induced bone loss and for the prevention of transplantation osteoporosis, and an adjuvant contribution to the disease-modifying therapy of RA and to the immunosuppressive therapy after transplantation can not be excluded.

    Highlights: •A GST-FSH fusion protein was successfully expressed in E. coli. •Immunization with GST-FSH antigen can raise high-titer anti-FSH polyclonal sera. •Anti-FSH polyclonal sera can neutralize osteoclastogenic effect of FSH in vitro. •FSH immunization can prevent bone loss in a rat osteoporosis model. -- Abstract: Osteoporosis, a metabolic bone disease, threatens postmenopausal women globally. Hormone replacement therapy (HTR), especially estrogen replacement therapy (ERT), is used widely in the clinic because it has been generally accepted that postmenopausal osteoporosis is caused by estrogen deficiency. However, hypogonadal α and β estrogen receptor null mice were only mildly osteopenic, and mice with either receptor deleted had normal bone mass, indicating that estrogen may not be the only mediator that induces osteoporosis. Recently, follicle-stimulating hormone (FSH), the serum concentration of which increases from the very beginning of menopause, has been found to play a key role in postmenopausal osteoporosis by promoting osteoclastogenesis. In this article, we confirmed that exogenous FSH can enhance osteoclast differentiation in vitro and that this effect can be neutralized by either an anti-FSH monoclonal antibody or anti-FSH polyclonal sera raised by immunizing animals with a recombinant GST-FSHβ fusion protein antigen. Moreover, immunizing ovariectomized rats with the GST-FSHβ antigen does significantly prevent trabecular bone loss and thereby enhance the bone strength, indicating that a FSH-based vaccine may be a promising therapeutic strategy to slow down bone loss in postmenopausal women.

Cognitive processing was assessed through masked recall. A total of 60 college-aged women viewed 12 gain-framed, 12 loss-framed, and 12 neutral-framed ads. Number of fixations, dwell time, and recall of gain-framed osteoporosis prevention ads were higher than loss-framed or neutral-framed ads, p < .01. Message recall was positively correlated with the number of fixations and dwell time for the gain-framed and neutral-framed messages, p < .01. These findings provide preliminary insight into potential mechanisms underlying message framing effects. PMID:23188916

    Glucocorticoid-induced osteoporosis (GIOP) is a serious problem for patients with rheumatic diseases requiring long-term glucocorticoid treatment. Alendronate, a bisphosphonate, has been recommended in the prevention of GIOP. However, the efficacy and safety of alendronate in preventing GIOP remains controversial. We performed a meta-analysis to investigate the efficacy and safety of alendronate in preventing GIOP in patients with rheumatic diseases.We retrieved randomized controlled trials from PubMed, EMBASE, and the Cochrane Library. Two reviewers extracted the data and evaluated the risk of bias and quality of the evidence. We calculated the risk ratio (RR) with a 95% confidence interval (CI) for dichotomous outcomes, and the mean difference (MD) with a 95% CI for continuous outcomes using Review Manager, version 5.3.A total of 339 studies were found, and 9 studies (1134 patients) were included. Alendronate was not able to reduce the incidence of vertebral fractures (RR = 0.63, 95% CI: 0.10-4.04, P = 0.62) and nonvertebral fractures (RR = 0.40, 95% CI: 0.15-1.12, P = 0.08). Alendronate significantly increased the percent change in bone mineral density (BMD) at the lumbar spine (MD = 3.66, 95% CI: 2.58-4.74, P < 0.05), total hip (MD = 2.08, 95% CI: 0.41-3.74, P < 0.05), and trochanter (MD = 1.68, 95% CI: 0.75-2.61, P < 0.05). Significant differences were not observed in the percent change in BMD at the femoral neck (MD = -0.33, 95% CI: -2.79 to 2.13, P = 0.79) and total body (MD = 0.64, 95% CI: -0.06 to 1.34, P = 0.07). No significant differences in the adverse events were observed in patients treated with alendronate versus the controls (RR = 1.00, 95% CI: 0.94-1.07, P = 0.89). The odds of gastrointestinal adverse events were significantly reduced (RR = 0.77, 95% CI: 0.62-0.97, P < 0.05).Our analysis suggests that alendronate can increase the percent change in BMD at the lumbar spine, total hip, and

    The definition of osteoporosis was originally formulated at a conference of the World Health Organization (WHO) in 1993 as 'a systemic skeletal disease characterized by decreased bone mass and altered micro-architecture of bone tissue, leading to enhanced bone fragility and risk of fractures'. Osteoporosis is characterized by low bone mineral density (BMD) and loss of the structural and bio-mechanical properties that are required to maintain bone homeostasis. This review aims to address the currently available options in prevention and treatment of osteoporosis. Management of osteoporosis includes non-pharmacological treatment - diet rich of calcium and vitamin D, healthy lifestyle, proper exercise plan, and pharmacological therapy. Combination of non-pharmacological and pharmacological treatment options have to be considered for prevention of osteoporosis and minimization of the risk of fractures. Given the heterogeneity of osteoporosis syndrome and lack of significant number of comparative studies, the choice of a pharmacological agents should be individualized. PMID:27180344

    Highlights: • Naringin possesses many pharmacological activities, promotes the proliferation of osteoblast. • Undecalcified histological obtain dynamic parameters of callus formation and remodeling. • Naringin regulate osteoclast apoptosis by mitochondrial pathway. - Abstract: Naringin, the primary active compound of the traditional Chinese medicine Rhizoma drynariae, possesses many pharmacological activities. The present study is an effort to explore the anti-osteoporosis potential of naringin in vivo and in vitro. In vivo, we used ovariectomized rats to clarify the mechanisms by which naringin anti-osteoporosis. In vitro, we used osteoclasts to investigate naringin promotes osteoclasts apoptosis. Naringin was effective at enhancing BMD, trabecular thickness, bone mineralization, and mechanical strength in a dose-dependent manner. The result of RT-PCR analysis revealed that naringin down-regulated the mRNA expression levels of BCL-2 and up-regulated BAX, caspase-3 and cytochrome C. In addition, naringin significantly reduced the bone resorption area in vitro. These findings suggest that naringin promotes the apoptosis of osteoclasts by regulating the activity of the mitochondrial apoptosis pathway and prevents OVX-induced osteoporosis in rats.

    As the average age of society increases, identifying and preventing osteoporosis becomes more important. According to the results of the Women's Health Initiative study, substitution of estradiol is not recommended in hormone replacement therapy (HRT), although phytoestrogens might be a safe alternative. In this study, the osteoprotective effects of genistein (Gen), resveratrol (Res) and 8-prenylnaringenin (8PN) were evaluated by analysing bone biomechanical strength and bone mineral density. After ovariectomy, 88 female rats received soy-free food (C), and according to their grouping, were fed estradiol (E), GEN, RES or 8PN for 12 weeks. The phytohormones were given in two dosages. To analyse the osteoprotective effects of the tested substances, bone biomechanical properties and bone mineral density (BMD) were evaluated on the upper tibial metaphysis. Bone biomechanical properties were significantly improved after treatment with E (F (max): 90.6 N) and 8PN (85.0 N) compared to GEN (76.0 N), RES (72.6 N) and C (76.6 N). Bone biomechanical properties with 8PN (yL: 55.7 N) supplementation reached a level similar to that seen after E (49.3 N) supplementation. Treatment with GEN (38.5 N) was not as effective as E and 8PN, but demonstrated improved biomechanical properties compared to C (40.1 N) and RES (36.3 N). E (Cn.Dn. 217 mg/cm (3)) and 8PN (165 mg/cm3) showed superior results in the analysis of bone mineral density compared to C (112 mg/cm (3)). GEN (164 mg/cm (3)) also demonstrated superior results, though not as good as E and 8PN. RES (124 mg/cm (3)) revealed no effect on bone density. Treatment with 8PN resulted in very good biomechanical properties and showed an increased BMD. GEN had a smaller effect on bone biomechanical strength, while RES did not have an effect on bone biomechanical strength or BMD. Therefore, 8PN might be a safe alternative for HRT, but further studies are needed. PMID:18537073

    Many preventive and treatment strategies are now available for osteoporosis, offering many women the opportunity to forego its many complications. Exercise with calcium and vitamin D supplements is recommended for most patients. Estrogens are a preferred treatment but not acceptable to many women. Alendronate, a bisphosphonate, recently became available to treat osteoporosis. Calcitonin, subcutaneous or intranasal, also can be useful. PMID:9016728

    BACKGROUND NEEDs for Bones (NFB), based on the Health Belief Model, is a 4-lesson osteoporosis-prevention curriculum for 11-14 year-olds. This study examined the relationship between enjoyment of food tastings and interest in NFB. METHODS NFB was administered by teachers as part of standard practice and evaluated after the 4th lesson using a 21-item survey. Significant clustering of students within classrooms required use of random-intercept multilevel ordinal regression models in SAS proc GLIMMIX, with students nested within classrooms. Analyses considered tasting experience, eating attitudes, sex, grade, and cohort. RESULTS Students (N = 1619; 50% girls) participated from 85 4th-8th grade classrooms (47% 6th grade; 31% 7th grade) in 16 Pennsylvania SNAP-Ed eligible schools over 2 academic years. For all foods tasted, students who did not enjoy the food tasting were less interested in the lesson than students who did enjoy the food tasting (all p < .001); refried beans (OR 0.30), soy milk (OR = 0.55), cranapple juice (OR = 0.51), sunflower kernels (OR = 0.48), and Swiss cheese (OR = 0.49). CONCLUSIONS Enjoyment of food tasting activities can predict interest in nutrition education on osteoporosis prevention, supporting resource allocation and inclusion of food tasting activities in school-age nutrition education.

    Anthocyanins, one of the flavonoid subtypes, are a large family of water-soluble phytopigments and have a wide range of health-promoting benefits. Recently, an anthocyanin-rich compound from blueberries was reported to possess protective property against bone loss in ovariectomized (OVX) animal models. However, the active ingredients in the anthocyanin compound have not been identified. Here we show that delphinidin, one of the major anthocyanidins in berries, is a potent active ingredient in anti-osteoporotic bone resorption through the suppression of osteoclast formation. In vitro examinations revealed that delphinidin treatment markedly inhibited the differentiation of RAW264.7 cells into osteoclasts compared with other anthocyanidins, cyanidin and peonidin. Oral administration of delphinidin significantly prevented bone loss in both RANKL-induced osteoporosis model mice and OVX model mice. We further provide evidence that delphinidin suppressed the activity of NF-κB, c-fos, and Nfatc1, master transcriptional factors for osteoclastogenesis. These results strongly suggest that delphinidin is the most potent inhibitor of osteoclast differentiation and will be an effective agent for preventing bone loss in postmenopausal osteoporosis.

  9. Optimal vitamin D status for the prevention and treatment of osteoporosis.

    Vitamin D(3) (cholecalciferol) sufficiency is essential for maximising bone health. Vitamin D enhances intestinal absorption of calcium and phosphorus. The major source of vitamin D for both children and adults is exposure of the skin to sunlight. Season, latitude, skin pigmentation, sunscreen use, clothing and aging can dramatically influence the synthesis of vitamin D in the skin. Very few foods naturally contain vitamin D or are fortified with vitamin D. Serum 25-hydroxyvitamin D [25(OH)D; calcifediol] is the best measure of vitamin D status. Vitamin D deficiency [as defined by a serum 25(OH)D level of <50 nmol/L (<20 ng/mL)] is pandemic. This deficiency is very prevalent in osteoporotic patients. Vitamin D deficiency causes osteopenia, osteoporosis and osteomalacia, increasing the risk of fracture. Unlike osteoporosis, which is a painless disease, osteomalacia causes aching bone pain that is often misdiagnosed as fibromyalgia or chronic pain syndrome or is simply dismissed as depression. Vitamin D deficiency causes muscle weakness, increasing the risk of falls and fractures, and should be aggressively treated with pharmacological doses of vitamin D. Vitamin D sufficiency can be sustained by sensible sun exposure or ingesting at least 800-1000 IU of vitamin D(3) daily. Patients being treated for osteoporosis should be adequately supplemented with calcium and vitamin D to maximise the benefit of treatment. PMID:18020534

    Osteoporosis is characterized by skeletal degeneration with low bone mass and destruction of microarchitecture of bone tissue which is attributed to various factors including inflammation. Women are more likely to develop osteoporosis than men due to reduction in estrogen during menopause which leads to decline in bone-formation and increase in bone-resorption activity. Estrogen is able to suppress production of proinflammatory cytokines such as IL-1, IL-6, IL-7, and TNF-α. This is why these cytokines are elevated in postmenopausal women. Studies have shown that estrogen reduction is able to stimulate focal inflammation in bone. Labisia pumila (LP) which is known to exert phytoestrogenic effect can be used as an alternative to ERT which can produce positive effects on bone without causing side effects. LP contains antioxidant as well as exerting anti-inflammatory effect which can act as free radical scavenger, thus inhibiting TNF-α production and COX-2 expression which leads to decline in RANKL expression, resulting in reduction in osteoclast activity which consequently reduces bone loss. Hence, it is the phytoestrogenic, anti-inflammatory, and antioxidative properties that make LP an effective agent against osteoporosis. PMID:22611381

    Despite recent advances in the understanding and treatment options for osteoporosis, this condition remains a serious public health issue. Adrenomedullin (AM) is a regulatory peptide with reported activity on bone remodeling. To better understand this relationship we built an inducible knockout for AM. An outstanding feature of knockout mice is their heavier weight due, in part, to the presence of denser bones. The femur of knockout animals was denser, had more trabeculae, and a thicker growth plate than wild type littermates. The endocrine influence of AM on bone seems to be elicited through an indirect mechanism involving, at least, the regulation of insulin, glucose, ghrelin, and calcitonin gene-related peptide (CGRP). To confirm the data we performed a pharmacological approach using the AM inhibitor 16311 in a mouse model of osteoporosis. Ovariectomized females showed significant bone mass loss, whereas ovariectomized females treated with 16311 had similar bone density to sham operated females. In conclusion, we propose the use of AM inhibitors for the treatment of osteoporosis and other conditions leading to the loss of bone mass. PMID:27445864

    Objectives: The aim of the present study was to investigate the anti-osteoporotic activity of Maxcal-C in ovariectomy (OVX)-induced osteoporosis in rats. Materials and Methods: Sham-operated control rats were designated as Group I; Group II animals served as OVX control; Group III OVX control rats treated with Calcium Sandoz (50 mg/kg, p.o.); Group IV and V OVX control rats treated with Maxcal-C (250 and 500 mg/kg, p.o.), respectively. All the aforementioned treatments were given for four weeks after the development of osteoporosis. At the end of the treatment, serum biochemical parameters such as serum calcium and alkaline phosphate were measured. After sacrificing the animals, femoral bone parameters with histology, body weight, and bone breaking strength of 5th lumbar vertebra were measured. Results: The treatment with Maxcal-C showed a significant improvement in serum biochemical, femoral bone parameters, and bone breaking strength of 5th lumbar vertebra with histopathological changes. Conclusion: The finding of the present study indicates that Maxcal-C showed a potential anti-osteoporotic activity. These results support the traditional use of Maxcal-C in the treatment of osteoporosis. PMID:26600648

    At first glance the human bone appears to be solid, rigid and unchangeable. But in point of fact this is not so, for a process of change is continuously going on, during which bone mass is resorbed and formed. Up until the age of 30 bone mass continues to be formed, although at an increasingly slower pace. A few years of equilibrium between bone formation and bone resorption follow. Thereafter, from about the age of 40, a continuous slow loss of bone mass sets in. This is considered to be a normal process of aging. But if the speed of resorption exceeds a certain degree and bone resorption increases, osteoporosis can develop after several years. Osteoporosis is therefore an illness in which bone mass has been massively resorbed over the past years and/or is being acutely resorbed. Given the altered demographic structure--an ever larger number of people living to an advanced age--the number of people affected by osteoporosis is increasing. Once the bone loss reaches a certain degree, there is a greater susceptibility to bone fractures. Particularly affected are the vertebrae, the neck of the femur, and the forearm. PMID:15719707

    Maintenance of bone health and quality requires mechanical strain, but the mechanical force needs to be within the bone's biomechanical competence. In osteoporosis, compression of vertebral bodies can be insidious. Therefore, absence of pain does not necessarily indicate absence of vertebral microfracture and deformity. Further, patients with previous vertebral fractures are at risk for further vertebral fractures and their associated morbidity. Exercise is a part of the comprehensive management of patients with osteoporosis and has been associated with improvement of quality of life and lowered risk of future fracture. The exercise prescription needs to match the needs of the patient. If exercise is not prescribed properly, then it may have negative consequences. In general, an exercise program, therapeutic or recreational, needs to address flexibility, muscle strength, core stability, cardiovascular fitness, and gait steadiness. As with pharmacotherapy, therapeutic exercises need to be individualized on the basis of musculoskeletal status and an individual's exercise interest. In osteoporosis, axial strength and stability are of primary importance. In particular, a spinal extensor strengthening program should be performed with progressive measured resistance as tolerated. To address falls and fractures, an exercise program should also include balance and lower extremity strength training. Proper dosing of oral cholecalciferol and calcium supplements can enhance the effect of strengthening exercises. Finally, a coordinated approach, such as the Spinal Proprioception Extension Exercise Dynamic (SPEED) program, can improve back extensor strength, the level of physical activity, and locomotion, and reduce back pain and fear and risk of falls.

    Osteoporosis (OP) in rheumatoid arthritis (RA) refers to a secondary immune-mediated metabolic osteopathy characterized by periarticular and systemic decreased bone mass, impaired bone strength and increased risk of fractures. According to some studies, adding milk in the diet helps to increase bone mineral density and to reduce the risk of osteoporosis and maintain normal levels of vitamin D. To study the state of mineral and bone metabolism in RA patients zeith osteopenic syndrome and to evaluate the effectiveness of treatment and prevention of OP by adding dry goat milk "Amalteya" in the diet. The study included 42 patients with a documented diagnosis of RA (ACR, 1987) - 23 men (mean age 59 years) and 19 postmenopausal women (mean age 62 years) with the presence of osteoporosis and osteopenia according to the dual-energy X-ray absorptiometry. 21 (50%) RA patients (main group) received standard antiosteoporotichesky (alendronate 70 mg/week + calcium 1000 mg/day + Vitamin D3 800 IU/day) therapy and milk powder Amalteya® (400 ml/day). The control group (21 patients with RA) received only standard antiosteoporotic therapy. Follow-up lasted for 6 months. The concentration of total calcium in the blood of RA patients was on average 2.33 mmol/l, ionized Ca - 1,18 mmol/l and inorganic P - 1,09 mmol/l, which corresponds to normal values. Vitamin D deficiency was found in 17,5% of patients, and failure - in 32,5% of patients with RA. After 6 months of the treatment it was found that b-CrossLaps levels tend to be reducing in both of the groups and with reduction of bone formation marker osteocalcin in the group not receiving goat milk. Also, due to the background of ongoing combinative therapy it was clear that concentrations of 1,25(OH)2D and 25(OH)D in the blood serum are increasing (by 18,5-28,2% at the main group and by 8,0-17,9% at the control group), however, inter-group differences was below the level of the reliable importance.

    A community-based project for the prevention of cardiovascular diseases was undertaken in 1989 in a rural Danish municipality (Slangerup) with about 8000 inhabitants. Project goals were to draw attention to project activities and improve smoking, eating and exercise behaviours. The intervention was planned using the social learning theory, a communication-behaviour change model and community organisation principle. The strategy used for intervention involved both mass communication and active involvement of the local population in group activities. The objectives of the intervention were assessed by data obtained from representative cross-section surveys in intervention and a control area at baseline (1989) and one year later. More respondents in the intervention (82%) than control (67%) area were aware of local health projects. Ten % reported that they stopped smoking within the last year, 39% ate less fat, and 28% did more exercise, with no differences between intervention and control area. Several explanations are proposed for the limited effect of the project on behaviours. One possible explanation is that the project almost ended up being a pure mass media campaign which may increase awareness, but, as experience shows, may have limited influence on adoption of new behaviour. The Danish population around 1990 is very well informed and educated in this field due to earlier nationwide interventions. No further behavioural effects are obtainable with mass media campaigns.

    The objective of the study was to analyze the consumption of dairy products and dietary calcium by women in the context of bone mineral density and to assess opportunities to prevent osteoporosis in a dietary manner. The study was carried out with 712 Polish women. In 170 women aged 32 to 59 bone mineral density (BMD) was measured. The data on the consumption of dairy products and dietary calcium and some other osteoporosis risk factors was collected from 712 women. The average calcium intake from a diet was 507 mg/day. Only 2% of the women met Polish calcium intake recommendations. During adulthood, dairy product consumption or dietary calcium intake did not differ significantly between women with low BMD (below -1 SD) and women with regular BMD (≥-1 SD) (47.4 vs. 44.3 servings/week and 459 vs. 510 mg/day, respectively, p > 0.05). The odds ratios adjusted for age, menstruation and BMI in women with upper BMD tercile in comparison to the reference group (bottom tercile) was 2.73 (95% CI: 1.14, 6.55; p < 0.05) for the daily consumption of dairy products during the pre-school period and 2.40 (95% CI: 1.01, 5.70; p < 0.05) for the daily consumption of dairy products during the school period. Two clusters of women were established. In the S1 cluster, low BMD (below -1 SD) was associated with older age (≥ 50 years), lack of menstrual cycle. In the S2 cluster, regular BMD (≥-1 SD) was related to younger aged women (<50 years), presence of menstrual cycle, consumption of higher level of dairy products (≥28 servings/week) during adulthood and daily intake of dairy products during childhood and adolescence. The results indicate that good bone health to the larg e extent depended upon the combined impact of dietary factors and some non-modifiable risk factors of osteoporosis such as age and the presence of menstruation. Consumption of dairy products in childhood and adolescence may improve bone mineral density and reduce the risk of osteoporosis in adult women. PMID

    Herba Epimedii (HEP) known as YinYangHuo in Chinese is the dried leaf of the Epimediium, and has been historically used in combination with other herbs to treat skeletal diseases in traditional Chinese medicine (TCM). Here, we review the historical TCM interpretation of the action of HEP, its use in clinical trials, its main phytochemical constituents and its pharmacological findings. 85 clinical trials were identified which used HEP in TCM prescriptions with other herbs to treat primary and secondary osteoporosis from 2005 to now. More than 60 individual compounds were isolated and characterized from HEP and studied in various animal and cell models. HEP and its constituents exhibited a variety of anti-resorptive and bone formation-stimulating effects, which target different pathways in the bone remodeling cycle. These compounds may provide new perspectives in alternative treatment regimes and reveal novel chemical scaffolds for the development of anti-osteoporotic drugs. These approaches are also useful for guiding our research to employ an integrative therapeutic approach to treat complex diseases such as osteoporosis diseases which could be superior to the conventional single target - single drug approach.

    Bone mass and skeletal muscle mass are controlled by factors such as genetics, diet and nutrition, growth factors and mechanical stimuli. Whereas increased mechanical loading of the musculoskeletal system stimulates an increase in the mass and strength of skeletal muscle and bone, reduced mechanical loading and disuse rapidly promote a decrease in musculoskeletal mass, strength and ultimately performance (i.e. muscle atrophy and osteoporosis). In stark contrast to artificially immobilised laboratory mammals, animals that experience natural, prolonged bouts of disuse and reduced mechanical loading, such as hibernating mammals and aestivating frogs, consistently exhibit limited or no change in musculoskeletal performance. What factors modulate skeletal muscle and bone mass, and what physiological and molecular mechanisms protect against losses of muscle and bone during dormancy and following arousal? Understanding the events that occur in different organisms that undergo natural periods of prolonged disuse and suffer negligible musculoskeletal deterioration could not only reveal novel regulatory factors but also might lead to new therapeutic options. Here, we review recent work from a diverse array of species that has revealed novel information regarding physiological and molecular mechanisms that dormant animals may use to conserve musculoskeletal mass despite prolonged inactivity. By highlighting some of the differences and similarities in musculoskeletal biology between vertebrates that experience disparate modes of dormancy, it is hoped that this Review will stimulate new insights and ideas for future studies regarding the regulation of atrophy and osteoporosis in both natural and clinical models of muscle and bone disuse.

    OBJECTIVE: To describe and analyse the types and circumstances of all natural and non-natural deaths among seamen on board Danish merchant ships. METHODS: Data on 147 cases were obtained from maritime authorities, an insurance company, shipping companies, hospitals, death registers, and death certificates in the period from 1986-93. RESULTS: The 53 natural deaths were dominated by cardiovascular diseases and infectious diseases. Insufficient treatment on board was identified as a contributing factor for death in some cases. Medical advice was not always sought and the advice given was in some cases insufficient. 73 fatal accidents were identified. The incidence of accidents of 5.29/10,000 person-years was 11.5 times higher than the incidence of 0.46/10,000 for the Danish male workforce ashore. 23 accidents (31%) were due to maritime casualties and 26 (36%) were occupational accidents. The remaining 24 (33%) were accidents during off duty hours including six self intoxications. Rough weather, inadequate awareness of safety, lack of use of personal protection devices, and inexperience were associated with many of the fatal injuries directly related to work. Alcohol played a major part in 12 out of 18 fatal injuries occurring during off duty hours. CONCLUSIONS: The maritime workplace was identified as a high risk workplace and in many aspects differs from the conditions ashore. Acute diseases and serious injuries pose special risks to seamen because of a lack of direct access to professional medical care at sea. Primary prevention of certain diseases is needed and possible. Improved training, improved systems of work, improved safety awareness, and greater use of personal protection devices are needed to prevent fatal injuries. Medical training of ships' officers providing medical care on board and specific training of doctors giving medical advise to ships should be improved to meet the needs. PMID:8664966

    Epidemiological studies have identified osteoporosis as a disease of significant public health impact and have delineated numerous potential risk factors. Nevertheless, it has proven difficult to establish preventive strategies for several reasons. First, there has been no final agreement on the definition of osteoporosis, which has hampered efforts to characterize the magnitude of the problem as a whole. Secondly, as osteoporosis is a multifactorial chronic disorder, effective programs for risk assessment and intervention depend on the development of complex disease models. In summarizing the contributions of epidemiological studies to the current understanding of osteoporosis this review intends to outline the scientific background for the European Vertebral Osteoporosis Study (EVOS) and its successors.

    Osteoporosis is defined by decreased bone density and microarchitectural deterioration that predispose to fragility fractures. The WHO diagnostic criteria of osteoporosis require bone densitometry but treatment is possible on the basis of high clinical fracture risk and can be assessed by the FRAX risk algorithm. All those subject to fracture risk should be advised about proper basic treatment of osteoporosis, including exercise, prevention of falls, smoking cessation, avoidance of alcohol intake, and dietary or supplemental abundance of calcium and vitamin D. Underlying diseases must be studied after diagnosis of osteoporosis even if treatment is initiated without densitometry. When indicated, specific osteoporosis therapy includes bisphosphonates, denosumab, teriparatide, strontium ranelate or SERMs. In hypogonadism, gonadal steroids may be indicated alone or in addition to a specific treatment. Treatment effect and continuation are assessed after 2 to 5 years. PMID:27400591

    Physicians are aware of the benefits of calcium and vitamin D supplementation. However, additional nutritional components may also be important for bone health. There is a growing body of the scientific literature which recognizes that silicon plays an essential role in bone formation and maintenance. Silicon improves bone matrix quality and facilitates bone mineralization. Increased intake of bioavailable silicon has been associated with increased bone mineral density. Silicon supplementation in animals and humans has been shown to increase bone mineral density and improve bone strength. Dietary sources of bioavailable silicon include whole grains, cereals, beer, and some vegetables such as green beans. Silicon in the form of silica, or silicon dioxide (SiO2), is a common food additive but has limited intestinal absorption. More attention to this important mineral by the academic community may lead to improved nutrition, dietary supplements, and better understanding of the role of silicon in the management of postmenopausal osteoporosis.

    Introduction Long-term glucocorticoid therapy is the leading cause of secondary osteoporosis. The management of glucocorticoid-induced osteoporosis (GIOP) seems to be inadequate in many European countries. Objective To evaluate the rate of screening and treatment of GIOP. Design Information was collected from a national public health-insurance database in our geographic area of Provence-Alpes-Côte-d'Azur and in Corsica, from September 2009 through August 2011. Patients We identified participants aged 15 years and over starting glucocorticoid therapy (≥7.5 mg of prednisone equivalent per day during at least 90 days consecutive). This cohort was compared with an age-matched and sex-matched population that did not receive glucocorticoids. Main outcome measures Bone mass, prescription of bone antiresorptive medication and use of calcium and/or vitamin D treatment. Results We identified 32 812 patients who were prescribed glucocorticoid therapy, yielding 1% prevalence. Incidence of glucocorticoid therapy was 2.8/1000 inhabitants/year. Males represented 44%, the mean age was 58 years. The median prednisone-equivalent dose was 11 mg/day (IQR 9–18 mg/day). 8% underwent bone mass measurement. Calcium and/or vitamin D, and bisphosphonates were prescribed in 18% and 12%, respectively. Results were lower for the control population: 3% underwent bone mass measurement and 3% received bisphosphonate therapy. The rates of osteodensitometry and treatments were higher in women over 55 years of age than in men and women 55 years of age and younger, and also when glucocorticoid therapy was initiated by a rheumatologist versus other physician specialty. Conclusions The management of GIOP remains very inadequate, despite the availability of a statutory health insurance system. Targeted interventions are needed to improve the management of GIOP.

    Secondary osteoporosis occurs as an isolated pathology or co-exists with types I and II osteoporosis. The gastroenterologist may come across osteoporosis or osteopenia in a patient with a gastrointestinal disease. This is often a young patient in whom investigations should be carried out and appropriate treatment initiated, aimed at preventing bone fractures and the formation of the best peak bone mass. Osteoporosis occurs in patients with the following conditions: Crohn's disease, ulcerative colitis, celiac disease, post gastrectomy patients, patients with short bowel syndrome, chronic hepatitis and cirrhosis, treated with steroids (steroid-induced osteoporosis) and patients using proton pump inhibitors chronically (state of achlorhydria). It is therefore necessary to approve a list of risk factors of secondary osteoporosis, the presence of which would be an indication for screening for osteoporosis, including a DXA study and the development of a separate algorithm for the therapeutic management of secondary osteoporosis accompanying gastrointestinal diseases, especially in premenopausal young women and young men, because there are currently no registered drugs with proven antifracture activity for this group of patients.

    With the aging of the population, there is a growing recognition that osteoporosis and fractures in men are a significant public health problem, and both hip and vertebral fractures are associated with increased morbidity and mortality in men. Osteoporosis in men is a heterogeneous clinical entity: whereas most men experience bone loss with aging, some men develop osteoporosis at a relatively young age, often for unexplained reasons (idiopathic osteoporosis). Declining sex steroid levels and other hormonal changes likely contribute to age-related bone loss, as do impairments in osteoblast number and/or activity. Secondary causes of osteoporosis also play a significant role in pathogenesis. Although there is ongoing controversy regarding whether osteoporosis in men should be diagnosed based on female- or male-specific reference ranges (because some evidence indicates that the risk of fracture is similar in women and men for a given level of bone mineral density), a diagnosis of osteoporosis in men is generally made based on male-specific reference ranges. Treatment consists both of nonpharmacological (lifestyle factors, calcium and vitamin D supplementation) and pharmacological (most commonly bisphosphonates or PTH) approaches, with efficacy similar to that seen in women. Increasing awareness of osteoporosis in men among physicians and the lay public is critical for the prevention of fractures in our aging male population. PMID:18451258

    Secondary osteoporosis is a bone disease characterized by decreased bone mass that predisposes fractures due to underlying disorders or medication. Disorders of the endocrine system, such as primary hyperparathyroidism, hyperthyroidism, hypogonadism, growth hormone deficiency, Cushing's syndrome, and anorexia nervosa frequently cause secondary osteoporosis. In those diseases, hormone excess or deficiency affects functions of osteoblasts, osteocyte, and osteoclasts, leading to aberrant bone remodeling. Bisphosphonates are the first-choice pharmacological agents for fracture prevention in most patients with secondary osteoporosis along with treatment of the underlying disease. PMID:26529938

    Background The purpose of our study is to assess practices of North American pediatric rheumatologists regarding monitoring, prevention, and treatment of low bone mineral density (BMD) in children on long-term glucocorticoid treatment. Long-term glucocorticoid therapy is associated with accelerated bone loss. Children with JIA and lupus have low baseline BMD and incident vertebral fractures commonly occur in these groups of patients even after a relatively short period of time being on systemic glucocorticoids. There are no established guidelines for identification, prevention, and treatment of glucocorticoid-induced bone loss in children. Methods A cross-sectional online survey was conducted with 199 physicians who were listed in the ACR database as practicing pediatric rheumatology in North America. Results 86 physicians (43%) responded; 87% were board-certified in pediatric rheumatology. 95% used dual energy X-ray absorptiometry as their primary modality for assessing BMD. 79% “rarely” or “never” obtained a baseline BMD measurement prior to initiation of glucocorticoid therapy. 42% of respondents followed BMD annually. 93% “frequently” or “always” prescribed calcium for patients on long-term corticosteroid therapy; 81% “frequently” or “always” prescribed vitamin D. In patients diagnosed with osteoporosis, 35%-50 % of the practitioners “sometimes”, “frequently” or “always” prescribed bisphosphonates. Bisphosphonates are prescribed at similar rates for male and female patients, and slightly more frequently for pubertal than for pre-pubertal patients. 96% of respondents “rarely” or “never” prescribed calcitonin for patients on long-term glucocorticoid therapy; 92% “rarely” or “never” prescribe this medication for patients with known osteopenia or osteoporosis. Conclusions Utilization of DXA in children on long-term corticosteroid therapy varies greatly among North American pediatric rheumatologists. Most

    The nutritional benefits of pomegranate have attracted great scientific interest. The pomegranate, including the pomegranate peel, has been used worldwide for many years as a fruit with medicinal activity, mostly antioxidant properties. Among chronic diseases, osteoporosis, which is associated with bone remodelling impairment leading to progressive bone loss, could eventually benefit from antioxidant compounds because of the involvement of oxidative stress in the pathogenesis of osteopenia. In this study, with in vivo and ex vivo experiments, we investigated whether the consumption of pomegranate peel extract (PGPE) could limit the process of osteopenia. We demonstrated that in ovariectomized (OVX) C57BL/6J mice, PGPE consumption was able to significantly prevent the decrease in bone mineral density (-31.9%; p < 0.001 vs. OVX mice) and bone microarchitecture impairment. Moreover, the exposure of RAW264.7 cells to serum harvested from mice that had been given a PGPE-enriched diet elicited reduced osteoclast differentiation and bone resorption, as shown by the inhibition of the major osteoclast markers. In addition, PGPE appeared to substantially stimulate osteoblastic MC3T3-E1 alkaline phosphatase (ALP) activity at day 7, mineralization at day 21 and the transcription level of osteogenic markers. PGPE may be effective in preventing the bone loss associated with ovariectomy in mice, and offers a promising alternative for the nutritional management of this disease. PMID:26569295

  17. Physical activity in the prevention and amelioration of osteoporosis in women : interaction of mechanical, hormonal and dietary factors.

    PubMed

    2005-01-01

    Osteoporosis is a serious health problem that diminishes quality of life and levies a financial burden on those who fear and experience bone fractures. Physical activity as a way to prevent osteoporosis is based on evidence that it can regulate bone maintenance and stimulate bone formation including the accumulation of mineral, in addition to strengthening muscles, improving balance, and thus reducing the overall risk of falls and fractures. Currently, our understanding of how to use exercise effectively in the prevention of osteoporosis is incomplete. It is uncertain whether exercise will help accumulate more overall peak bone mass during childhood, adolescence and young adulthood. Also, the consistent effectiveness of exercise to increase bone mass, or at least arrest the loss of bone mass after menopause, is also in question. Within this framework, section 1 introduces mechanical characteristics of bones to assist the reader in understanding their responses to physical activity. Section 2 reviews hormonal, nutritional and mechanical factors necessary for the growth of bones in length, width and mineral content that produce peak bone mass in the course of childhood and adolescence using a large sample of healthy Caucasian girls and female adolescents for reference. Effectiveness of exercise is evaluated throughout using absolute changes in bone with the underlying assumption that useful exercise should produce changes that approximate or exceed the absolute magnitude of bone parameters in a healthy reference population. Physical activity increases growth in width and mineral content of bones in girls and adolescent females, particularly when it is initiated before puberty, carried out in volumes and at intensities seen in athletes, and accompanied by adequate caloric and calcium intakes. Similar increases are seen in young women following the termination of statural growth in response to athletic training, but not to more limited levels of physical activity

    Poncirin, a flavonoid isolated from the fruit of Poncirus trifoliata, possesses anti-bacterial and anti-inflammatory activities. However, the action of poncirin in bone biology is unclear. In this study, the in vivo and in vitro effects of poncirin in a glucocorticoid-induced osteoporosis (GIO) mouse model were investigated. Seven-month-old male mice were assigned to the following five groups: (1) sham-implantation (sham), (2) prednisolone 2.1 mg/kg/day (GC), (3) GC treated with 10 mg/kg/day of genistein, (4) GC treated with 3 mg/kg/day of poncirin, (5) and GC treated with 10 mg/kg/day of strontium (GC + SrCl(2)). After 8 weeks, bone loss was measured by microcomputed tomography. Osteocalcin (OC) and C-terminal telopeptides of type I collagen (CTX) were evaluated in sera. Runx2 protein, OC and osteoprotegerin (OPG) mRNA expression, alkaline phosphatase (ALP) activity, and mineral nodule assay were performed in C3H10T1/2 or primary bone marrow stromal cells. Poncirin significantly increased the bone mineral density and improved the microarchitecture. Poncirin increased serum OC, Runx2 protein production, expression of OC and OPG mRNA, ALP activity, and mineral nodule formation; and decreased serum CTX. These effects were more prominent in the poncirin group compared to the other positive control groups (genistein and strontium). The poncirin-mediated restoration of biochemical bone markers, increased bone mineral density, and improved trabecular microarchitecture likely reflect increased bone formation and decreased bone resorption in GIO mice.

    2015-01-01

    Articles that update the state of knowledge regarding osteoporosis run the risk of quickly becoming obsolete because research and studies on osteoporosis today are arousing great interest among researchers, the pharmaceutical and medical equipment industries, governments and even WHO. All orthopedists know about osteoporosis because of its most deleterious effect: osteoporotic fracture. Osteoporosis without fractures does not arouse suspicion because this is a pathological condition with a nonspecific clinical profile. Osteoporotic fractures have an economic cost (from treatment), a social cost (from its sequelae) and a medical cost (from deaths). Many fractures could be avoided through diagnosing osteoporosis prior to the first fracture and thus many temporary and permanent disabilities could be avoided and many lives saved. Awareness of the risk factors for osteoporosis raises suspicions and bone densitometry aids in diagnosis. Treatment should be based on the physiopathology of the disease. Hence, for prevention or treatment of osteoporosis, the activity of osteoclasts should be diminished or the activity of osteoblasts should be increased, or both. Treatment that reduces the incidence of fractures by improving the bone geometry and microarchitecture would be ideal. Newly formed bone tissue needs to have good cell and matrix quality, normal mineralization, a good ratio between mineralized (mechanically resistant) and non-mineralized (flexible) bone, and no accumulated damage. The ideal treatment should have a positive remodeling rate and fast and long-lasting therapeutic effects. Such effects need to be easily detectable. They need to be safe. PMID:27022545

    Summary Osteoporosis is a metabolic bone disease characterized by loss of bone mass and strength, resulting in increased risk of fractures. It is classically divided into primary (post-menopausal or senile), secondary and idiopathic forms. There are many rare diseases, that cause directly or indirectly osteoporosis. The identification and classification of most of these rare causes of osteoporosis is crucial for the specialists in endocrinology and not, in order to prevent this bone complication and to provide for an early therapy. Several pathogenic mechanisms are involved, including various aspects of bone metabolism such as: decreased bone formation, increased bone resorption, altered calcium, phosphorus and/or vitamin D homeostasis, and abnormal collagen synthesis. In this review, less common forms of primary and secondary osteoporosis are described, specifying, if applicable: genetic causes, epidemiology, clinical features, and pathogenic mechanisms causing osteoporosis. A greater awareness of all rare causes of osteoporosis could reduce the number of cases classified as idiopathic osteoporosis and allow the introduction of appropriate and timely treatments.

    This study explored the Smoking Prevention and Cessation Partnership (SPCP) which builds upon a collaboration between two Danish municipalities targeted at the prevention of tobacco smoking. The aim of the study was to describe the processes of SPCP, to examine the difficulties this collaboration faced, and to assess how these experiences could be used to improve future partnership collaboration. We employed qualitative methodology comprising 12 semi-structured one-to-one interviews with SPCP’s stakeholders and an analysis of the partnership documents and reports. The findings suggested that the main potentials of the partnership were the personal relations between the members and stakeholders with the possibilities of the creation of new connections with other actors. Barriers to successful partnership building were the implementation of the new Local Government Reform as a competing task, and that the two municipalities were heterogenic in respect to organizational issues and working methods. Other impediments included the lack of continuity in leadership, the lack of clarity regarding the form of collaboration and roles, as well as different expectations of the stakeholders. We conclude that four factors remain critical for partnerships. The first is the clarity of the collaborative effort. Second, partnerships need to take into account the structural circumstances and culture/value systems of all stakeholders. Third is the impact of contextual factors on the development of the partnership; and the fourth factor is the bearing of personal/individual factors on the partnership e.g., personal engagement in the project. Early attention to these four factors could contribute to more effective partnership working. PMID:21139870

  2. Bazedoxifene and Conjugated Equine Estrogen: A Combination Product for the Management of Vasomotor Symptoms and Osteoporosis Prevention Associated with Menopause.

    2016-05-01

    Bazedoxifene (BZA), a third-generation selective estrogen receptor modulator (SERM), has been combined with conjugated equine estrogen (CE) to create a tissue selective estrogen complex (TSEC) for the management of vasomotor symptoms (VMS) and the prevention of osteoporosis (OP) associated with menopause. Both of these outcomes of menopause contribute to significant negative effects on quality of life and increases in utilization of health care resources and dollars. Current treatment modalities for VMS and OP include estrogen therapy that requires the use of progestin in women who have a uterus to reduce the risk of endometrial hyperplasia and resultant cancer. However, progestin use results in nuisance bleeding as well as a further increased risk of breast cancer when combined with estrogen. And while SERMs can be used to prevent OP, their use alone has been shown to increase hot flashes. The combination of BZA and CE does not require progestin treatment with CE as the BZA component acts as an antagonist on endometrial tissue. The U.S. Food and Drug Administration approval of BZA/CE in 2013 was based on a series of five phase 3 studies known as the Selective estrogens, Menopause And Response to Therapy (SMART) trials. These trials, in their entirety, evaluated the impact of BZA/CE on VMS frequency and severity, bone mineral density, bone turnover markers, vaginal symptoms, lipid profiles, sleep, quality of life, breast density, and endometrial safety. The approved dose of BZA/CE is 20 mg BZA and 0.45 mg CE. Although this TSEC manages VMS while opposing breast and endometrial proliferation, preventing bone resorption, and improving lipid profiles, long-term experience with BZA/CE is currently lacking.

    Lifestyle-related diseases other than type 2 diabetes mellitus and chronic kidney disease have also been reported in recent studies to have a possible effect on bone metabolism. In particular, evidence is accumulating regarding decreases in bone mineral density and an increased risk of fracture due to chronic obstructive pulmonary disease (COPD). In COPD, the fracture risk increases in both men and women, and the condition is considered a risk factor independent of glucocorticoid administration. Moreover, since kyphosis resulting from vertebral fractures adversely affects respiratory function, assessment of osteoporosis is recommended for all patients with COPD, regardless of sex. As for dyslipidemia and hypertension, due to the possible involvement of various factors, no consensus has been reached regarding the effects of the condition itself on bone. PMID:26320534

    Highlight: • We first report that anti-osteopontin mAb could protect osteoporosis in mice. • Anti-osteopontin mAb could promote the osteoclast apoptosis. • Targeting osteopontin might have therapeutic potentials for osteoporosis. - Abstract: Osteopontin (OPN) is abundant in mineralized tissues and has long been implicated in bone remodeling. However, the therapeutic effect of targeting OPN in bone loss diseases and the underlying molecular mechanism remain largely unknown. Here, we reported that anti-OPN mAb (23C3) could protect against ovariectomy-induced osteoporosis in mice, demonstrated by microcomputed tomography analysis and histopathology evaluation. In vitro assay showed that 23C3 mAb reduced osteoclasts (OCs)-mediated bone resorption through promotion of mature OC apoptosis. Thus, the study has important implications for understanding the role of OPN in OC bone resorption and survival, and OPN antagonists may have therapeutic potential for osteoporosis and other osteopenic diseases.

    Background The health belief model (HBM) is the most commonly used conceptual framework for evaluating osteoporosis health belief and behaviors. The purpose of this study was to develop and evaluate the psychometric properties of a health belief model based questionnaire for exercise behavior for preventing osteoporosis among women aged 30 years and over. Methods This was a cross sectional study of a convenience sample of women aged 30 years and over in Tehran, Iran using a theory-based instrument (HOPE). The instrument contained 39 items covering issues relate to osteoporosis prevention behavior. In this methodological study, exploratory and confirmatory factor analyses were used for psychometric evaluation. The Cronbach’s alpha coefficient and Intraclass Correlation Coefficient (ICC) was used to evaluate the reliability of the scale. Results In all 240 women participated in the study. The mean age of participant was 39.2 ± 7.8 years. The initial analysis extracted nine factors for the questionnaire that jointly accounted for 66.5% of variance observed. Confirmatory factor analysis showed that the data obtained was fit with Health Belief Model (HBM) and self-regulation construct (X2 = 1132.80, df = 629, P < 0.0001, CFI = 0.94, GFI = 0.91, RMSEA = 0.05 and SRMR = 0.06). The Cronbach’s alpha coefficient for the subscales ranged from 0.72 to 0.90 and Intraclass Correlation Coefficient (ICC) ranged from 0.71 to 0.98; well above acceptable thresholds. Conclusions The HOPE was found to be appropriate instrument for measuring health belief and self-regulation for prevention of osteoporosis. PMID:24581300

In addition, secondary osteoporosis should be considered if the bone density Z-score is -2.5 or less. Consider the fracture site and presence of other clinical clues to guide investigations for an underlying cause. The tests to use are those that are indicated for the suspected cause. Baseline investigations include tests for bone and mineral metabolism (calcium, phosphate, alkaline phosphatase, 25-hydroxyvitamin D, parathyroid hormone), liver and kidney function, full blood count and thyroid-stimulating hormone.

    Osteoclasts play an important role in diseases involving bone loss. In this study, we assessed the effect of a plant-derived natural alkaloid (lycorine, or LY) on osteoclastogenesis in vitro and in vivo. Our in vitro study showed that receptor activator of nuclear factor-κB ligand (RANKL)-induced osteoclastogenesis could be inhibited by LY; this effect was due to inhibition of mitogen-activated protein kinase (MAPK) signalling via MAP kinase kinases (MKKs). The MAPK agonist anisomycin could partially rescue the inhibitory effect of LY. Furthermore, LY also played a protective role in both a murine ovariectomy (OVX)-induced osteoporosis model and a titanium particle-induced osteolysis model. These results confirmed that LY was effective in preventing osteoclast-related diseases in vivo. In conclusion, our results show that LY is effective in suppressing osteoclastogenesis and therefore could be used to treat OVX-induced osteoporosis and wear particle-induced osteolysis.

    2015-01-01

    Corticosteroid-induced osteoporosis is the most common form of secondary osteoporosis and the first cause in young people. Bone loss and increased rate of fractures occur early after the initiation of corticosteroid therapy, and are then related to dosage and treatment duration. The increase in fracture risk is not fully assessed by bone mineral density measurements, as it is also related to alteration of bone quality and increased risk of falls. In patients with rheumatoid arthritis, a treat-to-target strategy focusing on low disease activity including through the use of low dose of prednisone, is a key determinant of bone loss prevention. Bone loss magnitude is variable and there is no clearly identified predictor of the individual risk of fracture. Prevention or treatment of osteoporosis should be considered in all patients who receive prednisone. Bisphosphonates and the anabolic agent parathyroid hormone (1–34) have shown their efficacy in the treatment of corticosteroid-induced osteoporosis. Recent international guidelines are available and should guide management of corticosteroid-induced osteoporosis, which remains under-diagnosed and under-treated. Duration of antiosteoporotic treatment should be discussed at the individual level, depending on the subject's characteristics and on the underlying inflammation evolution. PMID:26509049

    Osteoporosis is associated with a number of lifestyle factors, including nutritional factors such as intake of calcium, protein, dairy food, fruits and vegetables and vitamin D status, and behavioural factors such as physical activity, smoking and alcohol consumption. Ensuring adequate calcium intake and vitamin D status and having regular weight-bearing physical activity throughout life are important for bone health and the prevention of osteoporosis and related fractures. Studies have shown that smoking and excessive alcohol intake have adverse effects on bone health and increase the risk of fracture. There is evidence suggesting that adequate protein intake and higher intake of fruits and vegetables are beneficial to bone health. PMID:25416958

    Osteoporosis represents a major and increasing public health problem with the aging of population. Major clinical consequences and economic burden of the disease are fractures. Many risk factors are associated with the fractures including low bone mass, hormonal disorders, personal and family history of fractures, low body weight, use of certain drugs (e.g. glucocorticoids), cigarette smoking, elevated intake of alchohol, low physical activity, insufficient level of vitamin D and low intake of calcium. This epidemiological review describes frequency, importance of risk factors and impact of osteoporosis and osteoporotic fractures. Objective measures of bone mineral density along with clinical assessment of risk factors can help identify patients who will benefit from prevention and intervention efforts and eventually reduce the morbidity and mortality associated with osteoporosis-related fractures.

Final number of clusters was determined to be 16, based on a cluster size of 20 and calcium intake parameters (effect size 250 mg, ICC 0.5 and standard deviation 290 mg) as it required the highest number of clusters. Sixteen workplaces were recruited from a pool of 97 workplaces and randomly assigned to intervention and control arms (eight in each). Women meeting specified inclusion criteria were then recruited to participate. Workplaces in the intervention arm received three participatory workshops and organisation wide educational activities. Workplaces in the control/standard care arm received print resources. Intervention workshops were guided by self-efficacy theory and included participatory activities such as goal setting, problem solving, local food sampling, exercise trials, group discussion and behaviour feedback. Outcomes measures were calcium intake (milligrams/day) and physical activity level (duration: minutes/week), measured at baseline, four weeks and six months post intervention. Discussion This study addresses the current lack of evidence for behaviour change interventions focussing on osteoporosis prevention. It addresses missed opportunities of using workplaces as a platform to target high-risk individuals with sedentary occupations. The intervention was designed to modify behaviour levels to bring about risk reduction. It is the first to address dietary and physical activity components each with unique intervention

    In the current context of longer life expectancy, the prevalence of osteoporosis is increasingly important. This is why development of new strategies of prevention is highly suitable. Pomegranate seed oil (PSO) and its major component, punicic acid (a conjugated linolenic acid), have potent anti-inflammatory and anti-oxidative properties both in vitro and in vivo, two processes strongly involved in osteoporosis establishment. In this study, we demonstrated that PSO consumption (5% of the diet) improved significantly bone mineral density (240.24±11.85 vs. 203.04±34.19 mg/cm(3)) and prevented trabecular microarchitecture impairment in ovariectomized (OVX) mice C57BL/6J, compared to OVX control animals. Those findings are associated with transcriptional changes in bone tissue, suggesting involvement of both osteoclastogenesis inhibition and osteoblastogenesis improvement. In addition, thanks to an ex vivo experiment, we provided evidence that serum from mice fed PSO (5% by gavage) had the ability to significantly down-regulate the expression of specific osteoclast differentiation markers and RANK-RANKL downstream signaling targets in osteoclast-like cells (RAW264.7) (RANK: negative 0.49-fold vs. control conditions). Moreover, in osteoblast-like cells (MC3T3-E1), it elicited significant increase in alkaline phosphatase activity (+159% at day 7), matrix mineralization (+271% on day 21) and transcriptional levels of major osteoblast lineage markers involving the Wnt/β-catenin signaling pathways. Our data also reveal that PSO inhibited pro-inflammatory factors expression while stimulating anti-inflammatory ones. These results demonstrate that PSO is highly relevant regarding osteoporosis. Indeed, it offers promising alternatives in the design of new strategies in nutritional management of age-related bone complications. PMID:23953990

    Background: Osteoporosis is the most common metabolic bone disease. The purpose of this study is to investigate the health belief model (HBM) and social cognitive theory (SCT) for osteoporosis preventive nutritional behaviors in women. Materials and Methods: In this quasi-experimental study, 120 patients who were women and registered under the health centers in Fasa City, Fars Province, Iran were selected. A questionnaire consisting of HBM constructs and the constructs of self-regulation and social support from SCT was used to measure nutrition performance. Bone mineral density was recorded at the lumbar spine and femur. The intervention for the experimental group included 10 educational sessions of 55-60 min of speech, group discussion, questions and answers, as well as posters and educational pamphlets, film screenings, and PowerPoint displays. Data were analyzed using SPSS 19 via Chi-square test, independent t-test, and repeated measures analysis of variance (ANOVA) at a significance level of 0.05. Results: After intervention, the experimental group showed a significant increase in the HBM constructs, self-regulation, social support, and nutrition performance, compared to the control group. Six months after the intervention, the value of lumbar spine bone mineral density (BMD) T-score increased to 0.127 in the experimental group, while it reduced to −0.043 in the control group. The value of the hip BMD T-score increased to 0.125 in the intervention group, but it decreased to −0.028 in the control group. Conclusions: This study showed the effectiveness of HBM and constructs of self-regulation and social support on adoption of nutrition behaviors and increase in the bone density to prevent osteoporosis.

    Although various osteoporosis medications have become available with proven effects for protecting against bone fracture, such osteoporosis treatment is only given to 20 to 25% of those eligible in Japan. The most urgent task at present is to increase the treatment rate. The guidelines for prevention and treatment of osteoporosis were revised in 2015 and now include criteria for commencing medical treatment. However, guidelines for management of osteoporosis, including the duration of medical treatment for osteoporosis, are still under discussion. PMID:26529921

    Animal models will continue to be important tools in the quest to understand the contribution of specific genes to establishment of peak bone mass and optimal bone architecture, as well as the genetic basis for a predisposition toward accelerated bone loss in the presence of co-morbidity factors such as estrogen deficiency. Existing animal models will continue to be useful for modeling changes in bone metabolism and architecture induced by well-defined local and systemic factors. However, there is a critical unfulfilled need to develop and validate better animal models to allow fruitful investigation of the interaction of the multitude of factors which precipitate senile osteoporosis. Well characterized and validated animal models that can be recommended for investigation of the etiology, prevention and treatment of several forms of osteoporosis have been listed in Table 1. Also listed are models which are provisionally recommended. These latter models have potential but are inadequately characterized, deviate significantly from the human response, require careful choice of strain or age, or are not practical for most investigators to adopt. It cannot be stressed strongly enough that the enormous potential of laboratory animals as models for osteoporosis can only be realized if great care is taken in the choice of an appropriate species, age, experimental design, and measurements. Poor choices will results in misinterpretation of results which ultimately can bring harm to patients who suffer from osteoporosis by delaying advancement of knowledge. PMID:11704974

    The present study aimed to investigate the effect of electroacupuncture stimulation at CV4 (also termed Guanyuan) on femoral osteocalcin also termed bone gla protein (BGP), alkaline phosphatase (ALP), bone mineral density (BMD) and biomechanics, as well as the Wnt-β-catenin signaling pathway in rats with postmenopausal osteoporosis. Female Sprague-Dawley rats (4.5-months old) were randomly divided into sham, Ovx, CV4 and mock groups (n=10/group). With the exception of those in the sham group, the rats were ovariectomized to induce postmenopausal osteoporosis. The rats in the CV4 and mock groups were given electroacupuncture at CV4 and non-acupoint, respectively. The rats in the Ovx model and sham groups underwent identical fixing procedures, but did not undergo electroacupuncture. Following treatment, hematoxylin and eosin staining was used to observe morphological changes in the left femoral trabecular bone, and a three-point-bending test was used to analyze femur biomechanics and determine the BMD. In addition, an enzyme-linked immunosorbent assay was used to measure the serum levels of ALP/BGP and reverse transcription-quantitative polymerase chain reaction was used detect the expression levels of Wnt3a, β-catenin and Runx2. In the present study, it was demonstrated that electroacupuncture at CV4 significantly improved the osteoporotic morphological changes that occurred in the ovariectomized rats, increased serum ALP and BGP levels, enhanced the maximum and fracture loads, increased BMD (P<0.01), and activated the Wnt-β-catenin signaling pathway. These findings demonstrated that electroacupuncture stimulation at CV4 affected bone formation and promoted bone metabolism in rats with postmenopausal osteoporosis, possibly by activating the Wnt-β-catenin signaling pathway.

    Recent epidemiological studies have revealed that osteoporosis is closely associated with common chronic diseases including diabetes, hypertension, chronic kidney disorders, and chronic obstructive pulmonary disease (COPD). COPD is a chronic inflammatory airway disease but now well known to be associated with various systemic comorbidities including osteoporosis. Osteoporosis and osteoporotic fractures are extremely common in COPD patients, which have significant impacts on their quality of life (QOL), activities of daily life (ADL), respiratory function, and possibly their prognosis. COPD-associated osteoporosis is however extremely under-recognized, hence undertreated. Recent studies have suggested that both decreased bone mineral density (BMD) and impaired bone quality compromise bone strength causing fractures in COPD. In COPD patients, various general clinical risk factors for osteoporosis are present including smoking, older age, low body weight, and physical inactivity. In addition, disease-related risk factors such as decreased pulmonary function, inflammation, glucocorticoid use and vitamin D deficiency/insufficiency have been linked to the development of osteoporosis in COPD. Increased awareness of osteoporosis in COPD, especially that of high prevalence of vertebral fractures is called upon among general physicians as well as pulmonologists. Routine screening for osteoporosis and risk assessment of fractures will enable physicians to diagnose COPD patients with comorbid osteoporosis at an early stage. Timely prevention of developing osteoporosis together with appropriate treatment of established osteoporosis may improve QOL and ADL of the COPD patients, preserve their lung function and eventually result in better prognosis in these patients.

    Osteoporosis or osteopenia occurs in about 44 million Americans, resulting in 1.5 million fragility fractures per year. The consequences of these fractures include pain, disability, depression, loss of independence, and increased mortality. The burden to the healthcare system, in terms of cost and resources, is tremendous, with an estimated direct annual USA healthcare expenditure of about $17 billion. With longer life expectancy and the aging of the baby-boomer generation, the number of men and women with osteoporosis or low bone density is expected to rise to over 61 million by 2020. Osteoporosis is a silent disease that causes no symptoms until a fracture occurs. Any fragility fracture greatly increases the risk of future fractures. Most patients with osteoporosis are not being diagnosed or treated. Even those with previous fractures, who are at extremely high risk of future fractures, are often not being treated. It is preferable to diagnose osteoporosis by bone density testing of high risk individuals before the first fracture occurs. If osteoporosis or low bone density is identified, evaluation for contributing factors should be considered. Patients on long-term glucocorticoid therapy are at especially high risk for developing osteoporosis, and may sustain fractures at a lower bone density than those not taking glucocorticoids. All patients should be counseled on the importance of regular weight-bearing exercise and adequate daily intake of calcium and vitamin D. Exposure to medications that cause drowsiness or hypotension should be minimized. Non-pharmacologic therapy to reduce the non-skeletal risk factors for fracture should be considered. These include fall prevention through balance training and muscle strengthening, removal of fall hazards at home, and wearing hip protectors if the risk of falling remains high. Pharmacologic therapy can stabilize or increase bone density in most patients, and reduce fracture risk by about 50%. By selecting high risk

    Synopsis Osteoporosis is now recognized as a major threat to health in aging men. Morbidity and mortality, particularly following hip fracture, are substantial. Whereas trabecular bone loss starts in early adulthood, loss of cortical bone only appears to occur from mid-life onwards. Declining bioavailable estradiol levels play an integral role in male age-associated bone loss. Both pharmacologic and supportive care interventions are important for optimal care in men at increased fracture risk. PMID:22877433

    Background Current health education programs for osteoporosis prevention are not strictly evidence-based. We assessed whether distribution of an evidence-based guideline improved such programs at municipal health centers. Methods This randomized controlled trial evaluated 100 municipal health centers throughout Japan that were randomly selected from those that planned to revise osteoporosis prevention programs. The implementation status of educational items recommended by the guideline was assessed before and after the intervention by evaluators blinded to the allocation. After the pre-intervention assessment, centers were randomly allocated in a 1:1 ratio to intervention and control groups by a minimization method defining region and city/town as stratification factors. Centers in the intervention group were given copies of the guideline; centers in the control group were instructed to use any information except the guideline. Analyses were performed on an intention-to-treat basis. Results The guideline was used by 50% of the intervention group. Before the intervention, there was no significant difference in the evidence-based status of health education between the groups. The post-intervention assessment showed that the implementation rates of health education on dietary calcium intake for postmenopausal women and exercise for elderly persons were higher in the intervention group. Specific advice on intakes of calcium and vitamin D and exercise became more evidence-based in the intervention group. Conclusions The findings suggest that the guideline helped healthcare professionals to improve health education programs by making them more evidence-based. However, the improvements seemed to be limited to items that the professionals felt prepared to improve. PMID:22214657

    This article reviews the manifestations and risk factors associated with osteoporosis in childhood, the definition of osteoporosis and recommendations for monitoring and prevention. As well, this article discusses when a child should be considered a candidate for osteoporosis therapy, which agents should be prescribed, duration of therapy and side effects. There has been significant progress in our understanding of risk factors and the natural history of osteoporosis in children over the past number of years. This knowledge has fostered the development of logical approaches to the diagnosis, monitoring, and optimal timing of osteoporosis intervention in this setting. Current management strategies are predicated upon monitoring at-risk children to identify and then treat earlier rather than later signs of osteoporosis in those with limited potential for spontaneous recovery. On the other hand, trials addressing the prevention of the first-ever fracture are still needed for children who have both a high likelihood of developing fractures and less potential for recovery. This review focuses on the evidence that shapes the current approach to diagnosis, monitoring, and treatment of osteoporosis in childhood, with emphasis on the key pediatric-specific biological principles that are pivotal to the overall approach and on the main questions with which clinicians struggle on a daily basis. The scope of this article is to review the manifestations of and risk factors for primary and secondary osteoporosis in children, to discuss the definition of pediatric osteoporosis, and to summarize recommendations for monitoring and prevention of bone fragility. As well, this article reviews when a child is a candidate for osteoporosis therapy, which agents and doses should be prescribed, the duration of therapy, how the response to therapy is adjudicated, and the short- and long-term side effects. With this information, the bone health clinician will be poised to diagnose

    Bone loss associated with osteoporosis occurs with high frequency among the elderly and often results in debilitating fractures. A combination of lifestyle behaviors, genetic predisposition, and disease processes contributes to bone metabolism. Therefore, any discussion regarding bone health must address these factors. The impact of menopause on bone turnover has been generally well studied and characterized. Breastfeeding places significant stress on calcium metabolism and, as a consequence, directly influences bone metabolism. The most significant factors affecting bone mineral density (BMD) and bone metabolism are the duration and frequency of lactation, the return of menses, and pre-pregnancy weight. Although transient, lactation is associated with bone loss. As clinical guidelines and public health policies are being formulated, there is a compelling need for further investigation into the relationship of lactation, BMD, and subsequent risk of osteoporosis. Better understanding of this relationship will provide new opportunities for early intervention and ultimately help in the prevention of bone loss in postmenopausal women. PMID:12734029

    Osteoporosis is common in anorexia nervosa. It places these patients at increased lifetime risk for fractures. Bone loss may never recover completely even once weight is restored. The strongest predictors of osteoporosis include low body weight and amenorrhea. Loss of bone density can occur rapidly and very early in the course of anorexia nervosa. The etiology of bone loss in the patient with anorexia nervosa is multifactorial. In addition to reduced estrogen and progesterone, excess cortisol levels and low levels of insulin growth factor (IGF-1), a correlate for bone formation, are observed. Dual energy x-ray absorptiometry screening is important to assess bone density. However, successful treatments to reverse bone loss, in those with anorexia nervosa, are lacking. Early diagnosis and treatment of anorexia nervosa are paramount to prevent initial weight loss and subsequent loss of bone. PMID:21360368

    Osteoporosis is a disorder of bone formation and resorption balance. Advances in our knowledge of the molecular mechanisms of bone formation and resorption led to promising therapeutic targets for osteoporosis. In the novel biological drugs, denosumab, a monoclonal antibody against receptor activator of nuclear factor-κB ligand (RANKL) has been clinically applied by positive effect on bone mineral density, negative effect on bone resorption, preventive effect on fragility fractures and safety. Odanacatib, a cathepsin K inhibitor is drawing attention as an antiresorptive drug which has lower bone resorption potency than bisphosphoneate. On the other hand, BHQ-880, an anti-Dickkopf-1 (Dkk-1) antibody and romosozumab (AMG-785) , an anti-sclerostin antibody which activate Wnt/β-catenin signaling pathway are drawing attention as bone formation accelerators with no bone resorption acceleration. Clinical studies of these drugs are now ongoing and their clinical applications are expected. PMID:24870844

    The risk-stratified osteoporosis strategy evaluation study (ROSE) is a randomized prospective population-based study investigating the effectiveness of a two-step screening program for osteoporosis in women. This paper reports the study design and baseline characteristics of the study population. 35,000 women aged 65-80 years were selected at random from the population in the Region of Southern Denmark and-before inclusion-randomized to either a screening group or a control group. As first step, a self-administered questionnaire regarding risk factors for osteoporosis based on FRAX(®) was issued to both groups. As second step, subjects in the screening group with a 10-year probability of major osteoporotic fractures ≥15% were offered a DXA scan. Patients diagnosed with osteoporosis from the DXA scan were advised to see their GP and discuss pharmaceutical treatment according to Danish National guidelines. The primary outcome is incident clinical fractures as evaluated through annual follow-up using the Danish National Patient Registry. The secondary outcomes are cost-effectiveness, participation rate, and patient preferences. 20,904 (60%) women participated and included in the baseline analyses (10,411 in screening and 10,949 in control group). The mean age was 71 years. As expected by randomization, the screening and control groups had similar baseline characteristics. Screening for osteoporosis is at present not evidence based according to the WHO screening criteria. The ROSE study is expected to provide knowledge of the effectiveness of a screening strategy that may be implemented in health care systems to prevent fractures. PMID:25578146

    Considerable progress has been achieved recently in our understanding of the normal process by which bone mass is regulated. Age-related trabecular bone loss is characterized not simply by a global loss of bone but also by cortical porosity and loss of trabecular connections. Because bone strength depends on architectural as well as material properties, bone quantity alone cannot define fracture risk with precision. Traditional therapies for osteoporosis increase bone mass, and estrogen therapy, in particular, profoundly decreases fracture risk. The pharmacologic restoration of bone quantity and quality, however, remains elusive. Modern biotechnology offers the hope that progress may come about through the development of growth factors and other osteotropic compounds for clinical use. Images PMID:1877231

    The purpose of this review is to describe the available evidence for osteoporosis treatments in young and premenopausal women. A review of articles evaluating the treatment or prevention of osteoporosis in young (age less than 50 years) or premenopausal women was conducted. Several trials evaluating the treatment of anorexia nervosa and use of hormone therapy in those women, the use of bisphosphonates in women undergoing chemotherapy for breast cancer and the use of bisphosphonates, teriparatide and vitamin D in women with glucocorticoid-induced osteoporosis are described. Limited data were found to support the treatment of osteoporosis in women with idiopathic osteoporosis or cystic fibrosis, or after kidney transplant. The evidence for treatment of osteoporosis in premenopausal women is not nearly as robust as that for postmenopausal osteoporosis. Although fracture risk in the premenopausal population is low, women with secondary osteoporosis may benefit from treatment with various agents, depending upon the condition. PMID:24328599

    Introduction: Osteoporosis is a major problem in today's world, being characterized by decreased bone mass and bone change. Due to deficiency of theory-based studies in young population, especially in students, there are significant knowledge gaps of effective planning. Thepresent study was performed in response to this need. The present study investigated the effect of an empowerment program on physical activity related stages of change and self-efficacyin preventing osteoporosis among university students. Methods:In this randomized controlled trial (IRCT: IRCT201212016261N2), 152 female students of Shiraz University of Medical Sciences were selected through multi-stages cluster sampling and were randomly assigned to an experimental (n=76) and a control (n=76) group.The pre-and post-intervention data were collected using the Stages of Exercise Change Questionnaire (SECQ) of Marcos with Cronbach's alpha reliability of 0.89 and also the self-efficacy scale with a Cronbach's alpha reliability of 0.88 and Test-Retest Correlation Coefficient of 0.80. The educational intervention for the experimental group took place through problem-based learning method, small group discussion, and training manuals. In addition, training CDs and brochures were given to the subjects and short SMSs were sent to them. The data were analyzed throughSPSS, version 14, usingMann-Whitney test, Chi-square test, Wilcoxon and regression tests. Results:Pre-intervention findings showed that participants had behavioral constructs below the expected levels. The results showed that the experimental group received significant statisticalincrease after the intervention in stage of change. Before the intervention, the mean scores of stages of changes in the experimental groups was 2.28±0.86 but this rose to 3±0.84 in the first post-test and 3.22±0.84 in the second post-test. The control group showed a significant increase in stage of change without intervention (pre-test 2.04±0.82, first post

Techniques were developed to determine total skeletal calcium content with in vivo neutron activation analysis and to induce osteoporosis (in about three months) with low calcium diet, corticosteroid or heparin treatment in experimental animals. Genetic influence was demonstrated: C3H/St (Ha) mice were more susceptible to osteoporosis by all three modalities than C57B1/6 (J) mice. Fluoride was ineffective in preventing osteoporosis induced by either of these three modalities. Heparin induced osteoporosis was prevented by conjugated estrogens, progestins or their combinations. Progestins were shown in other studies to inhibit estrogen induced metaplasia and neoplasia. Combining estrogens with progestin may result in an increased therapeutic index for the prevention of postmenopausal osteoporosis. Human and salmon calcitonin, Deca - Durabolin, an anabolic steroid, Mopidamole, a pyrimidopyrimidine derivative, Trental, a methylxanthine derivative, certain 2-thiophene carboxylic acid derivatives and imidazoquinazolines exhibited anti-osteoporotic effects.

    Osteoporosis remains a significant clinical problem despite effective therapies. Many patients cannot or will not take currently available therapies. For this reason research continues in search of more effective and more tolerable agents. Anabolic agents offer a unique mechanism of action. The anabolic agents parathyroid hormone and strontium will be discussed. The investigational bisphosphonates ibandronate, minodronate and zoledronic acid may offer the advantage of less frequent dosing. Arzoxifene, bazedoxifene, lasofoxifene, MDL-103,323 and ospemifene are investigational selective oestrogen receptor modulators shown to be effective in animal studies and are now in clinical studies. Tibolone is a tissue-specific steroid that is currently used in Europe for prevention and treatment of osteoporosis. Multiple studies have shown efficacy in improving bone mineral density, but no fracture studies have been conducted to date. While studies of the effect of isoflavones on bone mineral density have been encouraging, a large, multi-centre study in Europe showed no effect of isoflavones on fractures. The newly described agent osteoprotegerin has been shown in early studies to inhibit bone turnover. Other agents with unique mechanisms of action in early development include cathepsin K inhibitors, integrin receptor inhibitors, nitrosylated non-steroidal anti-inflammatory agents and Src inhibitors. The efficacy of statins in bone continues to be debated with no prospective, randomised studies yet to confirm the suggestion of benefit seen in epidemiological studies. PMID:12665416

    Skeletal tissue is formed during the first two decades of life; then a constant bone mass is maintained until 40 y of age. In the case of women, the bone mass is rapidly reduced at menopause at around 50 y of age. After that, bone mass slowly decreases in both men and women who have passed the 70-y-old mark. The National Institute of Health Consensus Conference adopted the definition of osteoporosis as a skeletal disorder that is characterized by compromised bone strength leading to a predisposition for and an increased risk of fracture. Since osteoporotic fractures are the third-highest cause for becoming bedridden, the maintenance of healthy bones is an important factor in extending a person's healthy lifespan. Bone mass is influenced by many factors, such as nutrition, physical activity, smoking and alcohol intake, as well as by genetic factors. Thus, a healthy diet providing balanced nutrients including calcium, vitamin D, vitamin K and protein, regular physical activity, and not smoking help maintain bone health and delay or prevent osteoporosis. Some functional foods containing soy isoflavones, milk basic protein and n-3 fatty acid may help promote bone health. PMID:26598829

    Costs of male osteoporosis may have increased due to population aging and change of treatment patterns. This cost-of-illness study provides a current estimate of the economic burden of male osteoporosis in Germany. Routine claims data from six German sickness funds were analyzed and extrapolated to the German statutory health insurance (SHI). For men above the age of 50 with at least one ICD-10 osteoporosis-related diagnosis or osteoporosis-related fracture in 2010, direct costs related to osteoporosis were considered based on a payer's perspective. Total direct costs attributable to osteoporosis amounted to €728 million in 2010. The majority of these costs (71%) resulted from inpatient treatment due to fractures. Patients aged 75 and older caused approximately 63% of costs. Male osteoporosis represents a non-negligible economic burden for the German health care system. Targeted prevention and promotion measures should be offered both to men and women. PMID:25495596

    Osteoporosis is a complication of chronic liver disease, with impact on morbidity, quality of life, and survival. The progress of medicine and the new therapies stretched the disease's natural history and improved the survival of patients with liver disease. So, it is fundamental to make better the quality of life and to prevent complications. Metabolic bone disorders are common complications of chronic liver disease (CLD). Patients with CLD have an increased risk of bone fractures, with significant impact on morbidity, quality of life, and even on survival. Bone diseases, including osteomalacia, osteoporosis, and osteopenia, are frequently observed in many types of liver disease. The pathogenesis of damage and the mechanisms of bone loss are different in relation to the specific liver disease. The relevance of these conditions induced many authors to create a new nosographic entity known as "hepatic osteodystrophy", although this term is rarely used anymore and it is now commonly referred to as osteopenia or osteoporosis associated with chronic liver disease. This review is based on the personal experiences of the authors and upon research done of the available literature on this subject matter. The authors searched the PubMed database for publications containing the term "liver disease" in combination with "bone disease", "hepatic osteodistrophy", "osteoporosis", "osteopenia", "osteomalacia", and "fractures". They selected publications from the past 10 years but did not exclude older seminal publications, especially for colestatic liver diseases. This review of literature shows that osteoporosis crosses all CLD. It is important to underline that the progress of medicine and the new therapies stretched the disease's natural history and improved the survival of patients with CLD. It is fundamental to make better the quality of life and it is mandatory to prevent complications and in particular the osteoporotic ones, especially fractures. PMID:26846777

    As for most multifactorial disorders, the pathogenesis of osteoporosis is complex, and a different set of mechanisms may be operative in any given individual. However, there are certain common causes of bone loss and increased fracture risk with aging in most people. These include genetic factors contributing to the acquisition of peak bone mass, illnesses affecting skeletal growth and development, sex steroid deficiency following the menopause in women and with aging in men, and intrinsic, age-related changes in bone metabolism. Superimposed on these factors are specific secondary causes of bone loss, such as corticosteroid use or other illnesses affecting bone metabolism that may contribute to fracture risk in individuals exposed to these factors. The past decade has witnessed tremendous advances in our understanding of each of these various causes of bone loss, leading to the development of novel, mechanism-based therapeutic approaches to prevent and treat this important public health disorder.

  9. New therapeutics for osteoporosis.

    PubMed

    Ng, Kong Wah; Martin, T John

    2014-06-01

    Two new approaches for the treatment of osteoporosis are summarized, each having arisen out of important new discoveries in bone biology. Odanacatib (ODN) inhibits the enzyme, cathepsin K, that is essential for the resorbing activity of osteoclasts. It is effective in preventing ovariectomy-induced bone loss in preclinical studies, and a phase II clinical study has shown inhibition of resorption sustained over five years. Outcome of a phase III study is awaited. The finding from mouse and human genetics that Wnt signaling is a powerful inducer of bone formation led to developments aimed at enhancing this pathway. Of the several approaches towards this, the most advanced is with a neutralizing antibody against sclerostin, the osteocyte-derived inhibitor of Wnt signaling. Preclinical studies show a powerful bone anabolic effect, and a clinical phase II study shows dose-dependent increases in bone formation and decreases in bone resorption markers. PMID:24699340

    The prevalence and morbidity associated with osteoporosis and fractures in patients with spina bifida (SB) highlight the importance of osteoporosis prevention and treatment in early childhood; however, the issue has received little attention. The method for the selection of appropriate patients for drug treatment has not been clarified. Objective To review the literature concerning fracture risks and low bone density in paediatric patients with SB. We looked for studies describing state-of-the-art treatments and for prevention of secondary osteoporosis. Methods Articles were identified through a search in the electronic database (PUBMED) supplemented with reviews of the reference lists of selected papers. The main outcome measures were incidence of fractures and risk factors for fracture, an association between bone mineral density (BMD) and occurrence of fracture, risk factors of low BMD, and effects of pharmacological and non-pharmacological treatments on BMD and on the incidence of fractures. We considered as a secondary outcome the occurrence of fractures in relation to the mechanism of injury. Results Results indicated that patients with SB are at increased risk for fractures and low BMD. Risk factors that may predispose patients to fractures include higher levels of neurological involvement, non-ambulatory status, physical inactivity, hypercalciuria, higher body fat levels, contractures, and a previous spontaneous fracture. Limitations were observed in the number and quality of studies concerning osteoporosis prevention and treatment in paediatric patients with SB. The safety and efficiency of drugs to treat osteoporosis in adults have not been evaluated satisfactorily in children with SB. PMID:22330186

    Although several effective therapies are available for the treatment of osteoporosis in postmenopausal women and older men, there remains a need for the development of even more effective and acceptable drugs. Several new drugs that are in late-stage clinical development will be discussed. Abaloparatide (recombinant parathyroid hormone related peptide [PTHrP] analogue) has anabolic activity like teriparatide. Recent data from the phase 3 fracture prevention trial demonstrate that this agent is effective in reducing fracture risk. Inhibiting cathepsin K reduces bone resorption without decreasing the numbers or activity of osteoclasts, thereby preserving or promoting osteoblast function. Progressive increases in bone mineral density (BMD) have been observed over 5 years. Early data suggest that odanacatib effectively reduces fracture risk. Lastly, inhibiting sclerostin with humanized antibodies promotes rapid, substantial but transient increases in bone formation while inhibiting bone resorption. Marked increases in BMD have been observed in phase 2 studies. Fracture prevention studies are underway. The new therapies with novel and unique mechanisms of action may, alone or in combination, provide more effective treatment options for our patients. PMID:26354487

    Various hormonal disorders can influence bone metabolism and cause secondary osteoporosis. The consequence of this is a significant increase of fracture risk. Among pituitary disorders such effects are observed in patients with Cushing's disease, hyperprolactinemia, acromegaly, and hypopituitarism. Severe osteoporosis is the result of the coexistence of some of these disorders and hypogonadism at the same time, which is quite often. PMID:25873948

    Osteoporosis accounts for about 3 % of total European health-care spending. The low proportion of costs for the pharmacological prevention of osteoporotic fracture means that it is highly cost saving, especially in patient with severe osteoporosis or patients who cannot take certain osteoporosis medications due to issues of contraindications or tolerability. Following recent regulatory changes, strontium ranelate is now indicated in patients with severe osteoporosis for whom treatment with other osteoporosis treatments is not possible, and without contraindications including uncontrolled hypertension, established, current or past history of ischaemic heart disease, peripheral arterial disease, and/or cerebrovascular disease. We review here today's evidence for the safety and efficacy of strontium ranelate. The efficacy of strontium ranelate in patients complying with the new prescribing information (i.e. severe osteoporosis without contraindications) has been explored in a multivariate analysis of clinical trial data, which concluded that the antifracture efficacy of strontium ranelate is maintained in patients with severe osteoporosis without contraindications and also demonstrated how the new target population mitigates risk. Strontium ranelate is therefore an important alternative in today's management of osteoporosis, with a positive benefit-risk balance, provided that the revised indication and contraindications are followed and cardiovascular risk is monitored. The bone community should be reassured that there remain viable alternatives in patients in whom treatment with other agents is not possible and protection against the debilitating effects of fracture is still feasible in patients with severe osteoporosis.

    Osteoporosis is a skeletal disease characterized by decreased bone mass and microarchitectural changes in bone tissue that increase the susceptibility to fracture. Secondary osteoporosis is loosely defined as low bone mineral density or increased risk of fragility fracture caused by any factor other than aging or postmenopausal status. The purpose of this review is to discuss the current understanding of the pathophysiology and contribution to fracture risk of many of the more common causes of secondary osteoporosis, as well as diagnostic considerations, outlined by organ system. While not comprehensive, included are a wide array of diseases, conditions, and medications that have been associated with bone loss and susceptibility to fractures. The hope is to highlight the importance to the general clinician of screening for and treating the osteoporosis in these patients, so to limit the resultant increased morbidity associated with fractures.

  7. New Antiresorptive Therapies for Postmenopausal Osteoporosis

    PubMed Central

    2015-01-01

    Osteoporosis is a systemic skeletal disease whose risk increases with age and it is common among postmenopausal women. Currently, almost all pharmacological agents for osteoporosis target the bone resorption component of bone remodeling activity. Current antiresorptive agents are effective, but the effectiveness of some agents is limited by real or perceived intolerance, longterm adverse events (AEs), coexisting comorbidities, and inadequate long-term adherence. New antiresorptive therapies that may expand options for the prevention and treatment of osteoporosis include denosumab, combination of conjugated estrogen/bazedoxifene and cathepsin K inhibitors. However, the long-term efficacy and AEs of these antiresorptive therapies need to be confirmed in studies with a longer follow-up period. PMID:26046031

    The effect of inhaled glucocorticosteroids (ICS) on bone metabolism and subsequent osteoporosis is controversial. Explanations for this controversy include various study designs, duration of use, outcome measures, and population demographics of research studies with intranasal or inhalational ICS. Patients with poorly controlled asthma are at greatest risk of osteoporosis because they are commonly treated with intermittent or continuous systemic corticosteroids (SCS) or high-dose ICS. A 45-year-old Caucasian woman presents with moderate-to-severe asthma with frequent albuterol use and nighttime awakenings at least once weekly. She is on fluticasone/salmeterol 500/50 μg one inhalation twice daily and montelukast 10 mg/day. She requires prednisone 15 mg three times per day for 5 days up to three times a year. Is this patient at greater risk of osteopenia, characterized by a T-score between -1.0 and -2.5, and subsequent osteoporosis and an increased risk of fractures? If she has osteopenia, should she be treated with a bisphosphonate? The risk of osteoporosis and fracture increases significantly with frequent administration of SCS, and patients on such medications should undergo preventative measures and treatment. This study discuses factors that contribute to an increased risk of osteoporosis/osteopenia in patients with asthma and suggests recommendations based on the current literature. PMID:25039444

    Elevated serum levels of insulin-like growth factor binding protein-2 (IGFBP-2) and a precursor form of IGF-II are associated with marked increases in bone formation and skeletal mass in patients with hepatitis C-associated osteosclerosis. In vitro studies indicate that IGF-II in complex with IGFBP-2 has high affinity for bone matrix and is able to stimulate osteoblast proliferation. The purpose of this study was to determine the ability of the IGF-II/IGFBP-2 complex to increase bone mass in vivo. Osteopenia of the femur was induced by unilateral sciatic neurectomy in rats. At the time of surgery, 14-day osmotic minipumps containing vehicle or 2 microg IGF-II+9 microg IGFBP-2/100g body weight/day were implanted subcutaneously in the neck. Bone mineral density (BMD) measurements were taken the day of surgery and 14 days later using a PIXImus small animal densitometer. Neurectomy of the right hindlimb resulted in a 9% decrease in right femur BMD (P<0.05 vs. baseline). This loss in BMD was completely prevented by treatment with IGF-II/IGFBP-2. On the control limb, there was no loss of BMD over the 14 days and IGF-II/IGFBP-2 treatment resulted in a 9% increase in left femur BMD (P<0.05). Bone histomorphometry indicated increases in endocortical and cancellous bone formation rates and in trabecular thickness. These results demonstrate that short-term administration of the IGF-II/IGFBP-2 complex can prevent loss of BMD associated with disuse osteoporosis and stimulate bone formation in adult rats. Furthermore, they provide proof of concept for a novel anabolic approach to increasing bone mass in humans with osteoporosis.

    Background: Osteoporosis is a chronic disease characterized by a decrease in bone mineral density (BMD) and corruption of the microarchitectural structure of bone tissue. Objective: It was investigated whether methylprednisolone had a favorable effect on osteoporotic bone tissue in Oophorectomy induced osteoporotic rats whose endogenous adrenaline levels are suppressed with metyrosine. Materials and Methods: Bone Mineral Density, number of osteoblast-osteoclast, bone osteocalcin levels and alkaline phosphatase (ALP) measurements were performed. Obtained results were compared with that of alendronate. Results: Oophorectomy induced osteoporosis was exacerbated by methylprednisolone. Alentronate prevented ovariectomised induced osteoporosis, but it couldn’t prevent methylprednisolone +ovariectomised induced osteoporosis in rats. Conclusion: Combined treatment with methylprednisolon and metyrosine was the best treatment for preventing osteoporosis but metyrosine alone couldn’t prevent osteoporosis in ovariectomised rats.

    to conclude about efficacy (calcium, clodronate, etidronate, hormone replacement therapy, pamidronate, strontium, tiludronate, vitamin D). The low NNTs for the leading substances (ranges: 15-64 for alendronate, 8-26 for risedronate, 23 for calcitonin and 28-31 for raloxifene) confirm that effective and efficient drug interventions for treatment and prevention of osteoporotic vertebral fractures are available. Bisphosphonates have demonstrated similar efficacy in treatment and prevention of steroid-induced and male osteoporosis as in postmenopausal osteoporosis. The selection of the appropriate drug for treatment of vertebral osteoporosis from among a bisphosphonate (alendronate or risedronate), PTH, calcitonin or raloxifene will mainly depend on the efficacy, tolerability and safety profile, together with the patient's willingness to comply with a long-term treatment. Although reduction of vertebral fracture risk is an important criterion for decision making, drugs with proven additional fracture risk reduction at all clinically relevant sites (especially at the hip) should be the preferred options.

  13. [Osteoporosis and stress].

    PubMed

    Kumano, Hiroaki

    2005-09-01

    There may be three ways of relationship between stress and osteoporosis. The first is that stress induces some physiological changes leading to osteoporosis. The second is that stress induces behavioral distortion of eating, drinking, exercise, and sleep habits, which leads to osteoporosis. The third is that osteoporosis, on the other hand, brings about anxiety, depression, loss of social roles, and social isolation, which leads to stress. The susceptible sex and age groups are postmenopausal women and young women. The abrupt decrease of estrogen in postmenopausal women promotes reabsorption of bone, and it was also reported that the increase of interleukin-6 (IL-6) that is downstream of estrogen was related to the production of osteoclast and to the development of disability of the aged. Regarding the association with stress, while it was reported that depression or depressive states directly increased inflammation-induced cytokines including IL-6, it was also pointed out that stress-induced easy infectious may produce chronic infection, which indirectly increases inflammation-induced cytokines. Anorexia Nervosa that is assumed to be associated with adolescent developmental stress is noteworthy in young women. Amenorrhea is always present in this disease, and in addition to bone reabsorption associated with estrogen deficiency, the decrease of bone formation associated with malnutrition may be related to the development of osteoporosis.

    As men are less likely than women to develop osteoporosis, male osteoporosis remains poorly understood. However, elderly men have a clearly reduced bone mineral density and increased risk for fractures. In Japan, one in four patients with osteoporosis is male. Male osteoporosis is associated with not only reduction in androgen, but also estrogen, and differs from postmenopausal osteoporosis in that decreased bone formation is involved and that age-related changes in cortical bone structure and perforation of the trabeculae of cancellous bone are unlikely to occur. The proportion of secondary osteoporosis is higher for men than women;therefore, differential diagnosis is important in the diagnosis of male osteoporosis. In addition, it is recommended that bone mineral density be measured at the femoral neck or total hip in men. Men have a worse prognosis following fractures than women, and management of male osteoporosis is highly important for extending healthy life expectancy. PMID:27346307

    With an increased focus on wellness and health promotion, there is a need for community-based strategies to complement traditional strategies aimed at improving individual and aggregate health. An educational program on the prevention, diagnosis, and treatment of osteoporosis was provided for 188 women age 60 and older in three different community settings: churches, retirement homes, and senior citizen centers. The major purposes of the study were to determine whether a community-based program might (a) contribute to older women's knowledge about osteoporosis and (b) promote their intent to use this knowledge. Each participant completed a demographic profile, the Osteoporosis Risk Checklist, and the Osteoporosis Knowledge Questionnaire (OKQ), with the OKQ serving as a pre- and post-test. Before post-testing, a 30-min educational program was provided. Differences among the three groups were risk factors, prior knowledge about osteoporosis, and knowledge at the completion of the program. A majority of the clients indicated an intent to increase calcium in their diet, discuss osteoporosis with their health care provider, check their home environment for safety/falls, and discuss what they had learned with others. Nurses need to plan educational programs in all settings to teach older clients about the risk factors, prevention, diagnosis, and treatment of osteoporosis. PMID:12406180

    Summary Osteoporosis is a common disease characterised by a systemic impairment of bone mass and microarchitecture that results in fragility fractures. With an ageing population, the medical and socioeconomic impact of osteoporosis in general and postmenopausal osteoporosis in particular, will increase further. A detailed knowledge of bone biology with molecular insights into the communication between bone-forming osteoblasts and bone-resorbing osteoclasts and the orchestrating signalling network has led to the identification of novel therapeutic targets. Based on this, therapeutic strategies have been developed aimed at (I) inhibiting excessive bone resorption and by (II) increasing bone formation. The most promising novel treatments include denosumab, a monoclonal antibody against receptor activator of NF-κB ligand, a key osteoclast cytokine, odanacatib, a specific inhibitor of the osteoclast protease cathepsin K, and antibodies against the proteins sclerostin and dickkopf-1, two endogenous inhibitors of bone formation. This review provides an overview on these novel therapies and explains their underlying physiology. PMID:21450337

    The reduction of gravity-related forces on the skeleton creates a type of osteoporosis that is unique because its severity is dependent on the mechanical stress bearing function of the skeleton as well as the length of time that the forces are absent or reduced. Bones that bear weight under normal conditions are more affected than bones that normally do not bear weight. The cytokine environment and the cells in the affected bones are altered in time so that stem cells produce fewer new cells and the differentiated cells tend to be less active. These alterations in the local environment of the affected parts appear to resemble those of age- and disease-associated systemic forms of osteoporosis. The osteoporosis produced as a result of the loss of normal activity however, appears to be at least partially reversible through remobilization, strenuous exercise, and--possibly in the future--cytokine therapy.

    Osteoporosis in men is a heterogeneous disease that has received little attention. However, one third of worldwide hip fractures occur in the male population. This problem is more prevalent in people over 70 years of age. The etiology can be idiopathic or secondary to hypogonadism, vitamin D deficiency and inadequate calcium intake, hormonal treatments for prostate cancer, use of toxic and every disease or drug use that alters bone metabolism.Risk factors such as a previous history of fragility fracture should be assessed for the diagnosis. However, risk factors in men are very heterogeneous. There are significant differences in the pharmacological treatment of osteoporosis between men and women fundamentally due to the level of evidence in published trials supporting each treatment. New treatments will offer new therapeutic prospects. The goal of this work is a revision of the present status knowledge about male osteoporosis. PMID:23362466

    Osteoporosis is a major cause of morbidity in older people. There are a large number of risk factors for the development of osteoporosis. However, these risk factors eventually must mediate their effects through modulation of bone remodeling. A variety of compounds including hormones and nutrients modulate bone remodeling. In addition to these well-characterized substances, the immune system plays a role in bone remodeling through pro-inflammatory cytokines. Specifically, interleukin-1 (IL-1), IL-11, interferon-g are known to influence osteoclasts and osteoblasts. Recently, the cytokine IL-6 has joined ranks with these cytokines as a bone reactive agent. IL-6 has been shown to increase with age and menopause. Additionally, murine models suggest that IL-6 plays a central role in bone resorption. Finally, in vitro studies demonstrate that IL-6 induces osteoclast activity. In this review, we will discuss the pathogenesis of osteoporosis in the context of aging and IL-6. PMID:9463782

    Currently available drugs for the treatment of osteoporosis can still be improved in terms of pharmacokinetics, pharmacodynamics and management. New approaches for the development of innovative drugs are possible thanks to our increasing understanding of the bone tissue biology and the cellular and molecular processes that regulate it. One of the new anti-bone resorption agents, odanacatib, a selective cathepsin-K inhibitor, is in late phase III clinical research. Among new bone anabolic drugs, those that have an action on the Wnt signaling pathway appear to be particularly promising. The development of new compounds for the treatment of osteoporosis represents an excellent example of translational medicine efforts aimed to extend the range of treatment options for osteoporosis, a very common disease with a high social and economic impact, particularly when causing fractures.

    Anabolic agents represent an important new advance in the therapy of osteoporosis. Their potential might be substantially greater than the anti-resorptives. Because the anti-resorptives and anabolic agents work by completely distinct mechanisms of action, it is possible that the combination of agents could be significantly more potent than either agent alone. Recent evidence suggests that a plateau in BMD might occur after prolonged exposure to PTH. Anti-resorptive therapy during or after anabolic therapy might prevent this skeletal adaptation. Protocols to consider anabolic agents as intermittent recycling therapy would be of interest. Of all the anabolics, PTH is the most promising. However, there are unanswered questions about PTH. More studies are needed to document an anabolic effect on cortical bone. More large-scale studies are needed to further determine the reduction in nonvertebral fractures with PTH, especially at the hip. In the future, PTH is likely to be modified for easier and more targeted delivery. Oral or transdermal delivery systems may become available. Recently, Gowen et al have described an oral calcilytic molecule that antagonizes the parathyroid cell calcium receptor, thus stimulating the endogenous release of PTH. This approach could represent a novel endogenous delivery system for intermittent PTH administration. Rising expectations that anabolic therapies for osteoporosis will soon play a major role in treating this disease are likely to fuel further studies and the development of even more novel approaches to therapy.

    Background Fractures in older patients are common, morbid, and associated with increased risk of subsequent fractures. Inpatient and outpatient management and treatment of fractures can be costly. With more emphasis placed on quality care for Medicare beneficiaries, we studied if patients were receiving proper screening for osteoporosis and treatment after diagnosis of fracture. This study aims to determine if adequate screening and treatment for osteoporosis occurs in the postfracture period. Methods A retrospective analysis of Medicare beneficiaries aged 67 years or older was gathered from a single institution in both inpatient and outpatient visits. Based on International Classification of Diseases ninth revision codes, primary diagnosis of fractures of neck and trunk, upper limb, and lower limb were obtained in addition to current procedural terminology codes for fracture procedures. We studied patients who had been screened for osteoporosis with a bone mineral study or received osteoporosis treatment after their fracture. Results Medicare beneficiaries totaling 1,375 patients were determined to have an inclusion fracture between June 1, 2013 and November 30, 2014. At the time of our analysis on December 1, 2014, 1,219 patients were living and included in the analysis. Of these patients, 256 (21.0%) either received osteoporosis testing with bone mineral density or received treatment for osteoporosis. On sex breakdown, 208/820 (25.4%) females received proper evaluation or treatment of osteoporosis in comparison to 48/399 (12.0%) males. This is in comparison to the Centers for Medicare and Medicaid Services’ national average of 19.1% for osteoporosis management in females. Conclusion A minority of studied patients received evaluation or treatment for osteoporosis after their fracture. Postfracture investigation and treatment for osteoporosis in Medicare beneficiaries is inadequate. If improved, Medicare costs could be reduced by prevention of future fractures

    Current prevention strategies for low-trauma fractures amongst older persons depend on the notions that fractures are mainly caused by osteoporosis (pathophysiology), that patients at high risk can be identified (screening) and that the risk is amenable to bone-targeted pharmacotherapy (treatment). However, all these three notions can be disputed. Pathophysiology Most fracture patients have fallen, but actually do not have osteoporosis. A high likelihood of falling, in turn, is attributable to an ageing-related decline in physical functioning and general frailty. Screening Currently available fracture risk prediction strategies including bone densitometry and multifactorial prediction tools are unable to identify a large proportion of patients who will sustain a fracture, whereas many of those with a high fracture risk score will not sustain a fracture. Treatment The evidence for the viability of bone-targeted pharmacotherapy in preventing hip fracture and other clinical fragility fractures is mainly limited to women aged 65–80 years with osteoporosis, whereas the proof of hip fracture-preventing efficacy in women over 80 years of age and in men at all ages is meagre or absent. Further, the antihip fracture efficacy shown in clinical trials is absent in real-life studies. Many drugs for the treatment of osteoporosis have also been associated with increased risks of serious adverse events. There are also considerable uncertainties related to the efficacy of drug therapy in preventing clinical vertebral fractures, whereas the efficacy for preventing other fractures (relative risk reductions of 20–25%) remains moderate, particularly in terms of the low absolute risk reduction in fractures with this treatment.

    Osteoporosis is a skeletal disorder characterized by decreased bone mineral density and compromised bone strength predisposing to an increased risk of fractures. Although idiopathic osteoporosis is the most common form of osteoporosis, secondary factors may contribute to the bone loss and increased fracture risk in patients presenting with fragility fractures or osteoporosis. Several medical conditions and medications significantly increase the risk for bone loss and skeletal fragility. This review focuses on some of the common causes of osteoporosis, addressing the underlying mechanisms, diagnostic approach and treatment of low bone mass in the presence of these conditions.

    Highlights: • Single-nucleotide polymorphisms (SNPs) associated with osteoporosis were identified. • SNPs mapped close to or within VDR and ESR1 are associated with bone mineral density. • WNT signaling pathway plays a pivotal role in regulating bone mineral density. • Genetic studies will be useful for identification of new therapeutic targets. - Abstract: Osteoporosis is a skeletal disease characterized by low bone mineral density (BMD) and microarchitectural deterioration of bone tissue, which increases susceptibility to fractures. BMD is a complex quantitative trait with normal distribution and seems to be genetically controlled (in 50–90% of the cases), according to studies on twins and families. Over the last 20 years, candidate gene approach and genome-wide association studies (GWAS) have identified single-nucleotide polymorphisms (SNPs) that are associated with low BMD, osteoporosis, and osteoporotic fractures. These SNPs have been mapped close to or within genes including those encoding nuclear receptors and WNT-β-catenin signaling proteins. Understanding the genetics of osteoporosis will help identify novel candidates for diagnostic and therapeutic targets.

    Teriparatide (Forsteo - Eli Lilly) is the first parathyroid hormone derivative to be licensed for the treatment of women with postmenopausal osteoporosis. It is described as a "bone-formation agent", in contrast to established treatments, such as bisphosphonates, raloxifene, calcitriol and calcitonin, which reduce bone resorption. Here we consider whether teriparatide offers any worthwhile advantages over these other options. PMID:15587764

    Key Clinical Points Postmenopausal Osteoporosis Fractures and osteoporosis are common, particularly among older women, and hip fractures can be devastating. Treatment is generally recommended in postmenopausal women who have a bone mineral density T score of -2.5 or less, a history of spine or hip fracture, or a Fracture Risk Assessment Tool (FRAX) score indicating increased fracture risk. Bisphosphonates (generic) and denosumab reduce the risk of hip, nonvertebral, and vertebral fractures; bisphosphonates are commonly used as first-line treatment in women who do not have contraindications. Teriparatide reduces the risk of nonvertebral and vertebral fractures. Osteonecrosis of the jaw and atypical femur fractures have been reported with treatment but are rare. The benefit-to-risk ratio for osteoporosis treatment is strongly positive for most women with osteoporosis. Because benefits are retained after discontinuation of alendronate or zoledronic acid, drug holidays after 5 years of alendronate therapy or 3 years of zoledronic acid therapy may be considered for patients at lower risk for fracture.

    2016-03-01

    Beta-Thalassemia-associated osteoporosis is a multifactorial and complex condition. Different acquired and genetic factors are involved in its pathogenesis. These factors produce an imbalance in bone remodeling by inhibiting osteoblast activity and increasing osteoclast function, leading to bone loss and increased fracture risk. The management of patients presenting with thalassemia-associated osteoporosis should consist of the implementation of general measures and the prescription of a specific pharmacological agent, with the aim of reducing fracture risk and preventing disability and deterioration of quality of life. General measures include control of anemia, adequate chelation therapy, healthy nutrition and lifestyle, regular exercise, adequate management of comorbid conditions, hormone replacement therapy in patients with hypogonadism, and vitamin D supplementation/therapy. Among the pharmacological agents currently available for the management of osteoporosis in postmenopausal women and men, bisphosphonates have been shown to improve bone mineral density, to reduce bone turnover, and to decrease bone/back pain in patients with thalassemia-associated osteoporosis, with a good profile of safety and tolerability. On the other hand, there are limited experiences with other pharmacological agents (e.g., denosumab or teriparatide). The complexity of this condition presents diagnostic and therapeutic challenges and underscores the importance of a comprehensive and multidisciplinary approach. PMID:27060977

    In the prevention and treatment of osteoporosis, movement with muscle strengthening and proprioceptive training plays a major role. This was taken into consideration in the guidelines by the governing body on osteoporosis (Dachverband Osteoporose, DVO) from 2014 on prophylaxis, diagnosis and treatment of osteoporosis and in the DVO guidelines from 2008 on physiotherapy and exercise therapy for osteoporosis. Increases in lumbar bone density of between 0.5 % and 2.5 % can be achieved in women by strengthening exercises with high resistance. With this combination and strengthening of the quadriceps muscle a reduction of falls and hence the fracture risk could also be achieved. In traumatology, training for muscle strengthening is not always possible, especially for elderly patients. Practically relevant alternatives are regular walking and aquatraining, which may also lead to a significant increase in bone mineral density. Furthermore, large effects can be achieved with alternating side whole-body vibration (WBV) training with whole body vibration plates with only 3 days of training per week and with short training periods (15-20 min). Rates of increase in leg strength between 20 % and almost 40 % and in bone density between 0.5 % and 4 % in 6 months have been described. Whether and with what intensity whole body vibration therapy could be used for e.g. more rapid healing of fractures, is currently unclear. Initial positive results have been described in animal models. PMID:26467265

    The aim of this protocol is to provide a detailed description of male and female rodent models of osteoporosis. In addition to indications on the methods of performing the surgical procedures, the choice of reliable and safe anaesthetics is also described. Post-operative care, including analgesia administration for pain management, is also discussed. Ovariectomy in rodents is a procedure where ovaries are surgically excised. Hormonal changes resulting from ovary removal lead to an oestrogen-deprived state, which enhances bone remodelling, causes bone loss and increases bone fracture risk. Therefore, ovariectomy has been considered as the most common preclinical model for understanding the pathophysiology of menopause-associated events and for developing new treatment strategies for tackling post-menopausal osteoporosis. This protocol also provides a detailed description of orchidectomy, a model for androgen-deficient osteoporosis in rodents. Endocrine changes following testes removal lead to hypogonadism, which results in accelerated bone loss, increasing osteoporosis risk. Orchidectomised rodent models have been proposed to mimic male osteoporosis and therefore remain a valuable tool for understanding androgen deficiency in aged men. Although it would have been particularly difficult to assemble an internationally acceptable description of surgical procedures, here we have attempted to provide a comprehensive guide for best practice in performing ovariectomy and orchidectomy in laboratory rodents. Research scientists are reminded that they should follow their own institution's interpretation of such guidelines. Ultimately, however, all animal procedures must be overseen by the local Animal Welfare and Ethical Review Body and conducted under licences approved by a regulatory ethics committee. PMID:25852854

    Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory airway disease associated with various systemic comorbidities including osteoporosis. Osteoporosis and its related fractures are common and have significant impacts on quality of life and even respiratory function in patients with COPD. COPD-associated osteoporosis is however extremely undertreated. Recent studies have suggested that both decreased bone mineral density (BMD) and impaired bone quality contribute to bone fragility, causing fractures in COPD patients. Various clinical risk factors of osteoporosis in COPD patients, including older age, emaciation, physical inactivity, and vitamin D deficiency, have also been described. It is critically important for pulmonologists to be aware of the high prevalence of osteoporosis in COPD patients and evaluate them for such fracture risks. Routine screening for osteoporosis will enable physicians to diagnose COPD patients with comorbid osteoporosis at an early stage and give them appropriate treatment to prevent fracture, which may lead to improved quality of life as well as better long-term prognosis.

    The number of women with osteoporosis, ie, with reduced bone mass and the disruption of bone architecture, is increasing in India. While data on prevalence of osteoporosis among women in India come from studies conducted in small groups spread across the country, estimates suggest that of the 230 million Indians expected to be over the age of 50 years in 2015, 20%, ie, ~46 million, are women with osteoporosis. Thus, osteoporosis is a major public health problem in Indian women. Low calcium intakes with extensive prevalence of vitamin D deficiency, increasing longevity, sex inequality, early menopause, genetic predisposition, lack of diagnostic facilities, and poor knowledge of bone health have contributed toward the high prevalence of osteoporosis. Bone health may be optimized by creating an environment to achieve peak bone mass during adolescence, maintenance of healthy bone throughout the life cycle, and prevention of bone loss postmenopausal. In Indian women, calcium, vitamin D, and bisphosphonates are the commonest first-line therapies used. The use of other drugs such as hormone replacement therapy, estrogen agonists, calcitonin, parathyroid hormone, and denosumab is decided as per the affordability and availability of treatment options. Major gaps still remain in the diagnosis and management of osteoporosis, thus highlighting the need for more structured research in this area. This review focuses on the epidemiology of osteoporosis in Indian women and available treatments. PMID:26527900

    Aim: To evaluate the protective effects of strontium fructose 1,6-diphosphate (FDP-Sr), a novel strontium salt that combined fructose 1,6-diphosphate (FDP) with strontium, on bone in an ovariectomy-induced model of bone loss. Methods: Eighty female Sprague-Dawley rats were ovariectomized (OVX) or sham-operated. Three months later, the rats were assigned to six groups (10 for each): sham-operated, OVX control, OVX+FDP-Sr (110, 220, or 440 mg/kg), or OVX+strontium ranelate (SR, 180 mg/kg). Drugs were administered orally for 3 months. When the treatment was terminated, the following parameters were assessed: bone mineral density (BMD), the biomechanical properties of the femur and lumbar vertebrae, trabecular histomorphology, serum phosphorus, calcium, bone-specific alkaline phosphatase (B-ALP), tartrate-resistant acid phosphatase 5b (TRACP5b), N-telopeptide of type I collagen (NTx) and a series of markers for oxidative stress. Receptor activator of NF-κB ligand (RANKL) and osteoprotegerin (OPG) levels in serum were measured using ELISA and their gene expression levels in the bone were measured using R-T PCR. Results: Treatment with FDP-Sr (220 or 440 mg/kg) or SR (180 mg/kg) significantly increased the BMD and improved the bone microarchitecture and bone strength in OVX rats. The treatments also decreased in the levels of H2O2 and MDA, restored the CAT level in serum and bone marrow, increased the serum B-ALP and decreased NTx and TRACP 5b in OVX rats. Treatment with FDP-Sr decreased the RANKL level, and increased the OPG level in serum in a dose-dependent manner. It also significantly down-regulated the RANKL expression and up-regulated OPG expression in bone marrow. Conclusion: FDP-Sr may be an effectve treatment for postmenopausal osteoporosis that acts, in part, via a decrease in osteoclastogenesis through the OPG\\RANKL\\RANK pathway. PMID:22426695

    This longitudinal retrospective cohort study evaluated implementation of an intervention to improve management of osteoporosis after a fracture in a nonprofit group-model health maintenance organization (HMO) in the U.S. Pacific Northwest with 480,000 members and electronic medical record data. Participants were female HMO members aged 67 and older who sustained a qualifying clinical fracture(s) and who had not received a bone mineral density (BMD) measurement or osteoporosis treatment in the 12 months before the fracture (N=3,588). Phase 1 included outreach to clinicians and patients; Phase 2 added clinician and staff incentives. Primary outcome was "osteoporosis management"--receipt of a BMD measurement or osteoporosis medication in the 6 months after an index fracture. Before the intervention, 13.4% (95% confidence interval (CI)=12.0-14.8%) of patients had received osteoporosis management, and the time trend was not significant. Post-intervention, the probability of osteoporosis management increased on average 3.1% (95% CI=2.6-3.5%) every 2 months throughout both study phases without a significant added improvement in Phase 2. Improvement varied according to clinic and was less likely for patients with dementia. Overall, the probability of osteoporosis management increased from the baseline level of 13.4% to 44.0% (95% CI=40.0-48.0%) by the end of the study period (20 months post-intervention). The study found that an outreach program to primary care providers and patients improved the management of osteoporosis after a fracture. If widely implemented, this intervention could substantially improve the secondary prevention of osteoporosis. More-individualized interventions may be necessary for high-risk subgroups.

    The effect of 26,27-hexafluoro-1,25-dihydroxyvitamin D3 (F6-1,25(OH)2D3) on experimental osteoporosis in the rat induced by a combination of immobilization and ovariectomy was evaluated. F6-1,25(OH)2D3 increased the femur score and the photo-density. The administration of F6-1,25(OH)2D3 also significantly increased the dry weight, the ash weight and the ash content of the bone. Both F6-1,25(OH)2D3 and 1 alpha(OH)D3 showed a nearly dose-dependent effect and significant inhibition of the decrease of bone mass. Histomorphometry revealed a significant decrease of resorption by the administration of F6-1,25(OH)2D3. Bone formation rate in the F6-1,25(OH)2D3 treated group significantly decreased compared with the vehicle group. In conclusion, the pharmacological effective dose of F6-1,25(OH)2D3 was considered to prevent the osteoporotic decrease of bone mass by suppressing the elevated bone turnover. PMID:2350614

    The prevalence of osteoporosis is expected to increase with the ageing of the world's population. This article reviews the epidemiology, risk factors and health burden of osteoporosis. In the Global Burden of Disease (GBD) Study 2005, osteoporosis is studied as a risk factor for fracture by considering the bone-mineral-density (BMD) measurement as the continuous exposure variable. We have performed a systematic review seeking population-based studies with BMD data measured by dual-X-ray absorptiometry (DXA). The femoral neck was selected as the unique location and all values were converted into Hologic(®) to enable inclusion of worldwide data for analysis.

    Osteoporosis currently affects 10 million Americans and is responsible for more than 1.5 million fractures annually. The financial burden of osteoporosis is substantial, with annual direct medical costs estimated at 17 to 20 billion dollars. Most of these costs are related to the acute and rehabilitative care following osteoporotic fractures, particularly hip fractures. The societal burden of osteoporosis includes these direct medical costs and the monetary (eg, caregiver time) and nonmonetary costs of poor health. The aging of the US population is expected to increase the prevalence of osteoporosis and the number of osteoporotic fractures. Growth of the older adult population will pose significant challenges to Medicare and Medicaid, which bear most of the cost of osteoporosis. Efforts to address the looming financial burden must focus on reducing the prevalence of osteoporosis and the incidence of costly fragility fractures. PMID:20425518

    Osteoporosis is one of the established major consequences of long-duration spaceflights in astronauts seriously undermining their health after their returning on Earth. Indeed, astronauts typically lose more bone mass during one month than postmenopausal women on Earth lose in one year. To date, countermeasures mainly consist in exercise and supplementation while pharmacological treatment as those used in postmenopausal women are not routine. However, it is evident that exercise and supplementation alone are not enough to maintain bone homeostasis. In this paper we describe the current countermeasures for bone loss during long-term spaceflight, review the modern treatment which are successfully employed to prevent osteoporosis on Earth and that could be quickly used also for astronauts and finally focus on the recent cellular and molecular understanding of bone homeostasis which might provide the basis for the development of future targeted therapies.

  6. Osteoporosis: the role of genetics and the environment.

    PubMed

    Osteoporosis is partly genetically determined. The genetics of osteoporosis is polygenic in nature with multiple common polymorphic alleles interacting with each other and environmental factors to determine bone mass. A number of studies have attempted to dissect the genetic factors responsible for the pathogenesis of osteoporosis using genome-wide scanning and the candidate gene approach. However, the results of such studies among different populations have been mostly inconsistent, suggesting genetic heterogeneity of osteoporosis. It is likely that the cohort of genes indicating predisposition to the risk of osteoporosis may be different among populations with different ethnic backgrounds. The successful identification of susceptibility genes for osteoporosis should prove to be helpful in targeting preventive and therapeutic measures to individuals at higher risk and to render the effort more cost-effective. Information with regard to genetic variations is also likely to be useful in targeting preventive or therapeutic measures to subjects genetically determined to have better responsiveness. Intestinal calcium absorption is dependent on vitamin D receptor gene polymorphisms. Skeletal responsiveness to estrogen, particularly at lower doses, is related to polymorphisms in the estrogen receptor-alpha gene. Recently, circulating homocysteine levels have been shown to be associated with fracture risk. Folate and vitamin B supplements for reducing serum homocysteine and fractures in postmenopausal women have not been fully investigated. However, there is an interaction between folate status and methylenetetrahydrofolate reductase gene polymorphism on bone phenotypes. Due to recent technological advances, whole-genome association study is becoming more feasible. Genomic information with regard to the susceptibility to osteoporosis and the responsiveness to preventive or therapeutic modalities should supplement rather than replace conventional clinical information

    Osteoporosis is a major public health problem, affecting millions of people worldwide. The associated health care costs are growing in parallel with increases in elderly populations, and it is expected that the number of osteoporotic fractures will double over the next 50 years. The best way to address osteoporosis is prevention. Some interventions to maximize and preserve bone mass have multiple health benefits and are cost-effective. For example, modifications to diet and lifestyle can help to prevent osteoporosis, and could potentially lead to a significant decrease in fracture rates; and exercise is a valuable adjunct to programmes aimed at alleviating the risks and symptoms of osteoporosis. Practising exercise at a young age helps maximize the mineral density of bones while they are still growing and maturing, and continuing to excercise minimizes bone loss later in life. Not only does exercise improve bone health, it also increases muscle strength, coordination, balance, flexibility and leads to better overall health. Walking, aerobic exercise, and t'ai chi are the best forms of exercise to stimulate bone formation and strengthen the muscles that help support bones. Encouraging physical activity at all ages is therefore a top priority to prevent osteoporosis. PMID:14758410

    The report of the World Health Organization (WHO) of 2008 defines osteoporosis as a disease characterized by low bone mass and an increased risk of fracture. Postmenopausal osteoporosis is connected to the decrease in estrogens concentration as a result of malfunction of endocrine ovarian function. Low estrogens concentration causes increase in bone demineralization and results in osteoporosis. Physical activity, as a component of therapy of patients with osteoporosis, has been used for a long time now. One of the forms of safe physical activity is the vibration training. Training is to maintain a static position or execution of specific exercises involving the appropriate muscles on a vibrating platform, the mechanical vibrations are transmitted to the body of the patient. According to the piezoelectric theory, pressure induces bone formation in the electrical potential difference, which acts as a stimulant of the process of bone formation. Whole body vibration increases the level of growth hormone and testosterone in serum, preventing sarcopenia and osteoporosis. The aim of this study was to review the literature on vibration exercise in patients with postmenopausal osteoporosis based on the PubMed and Medline database. While searching the database, the following key words were used ‘postmenopausal osteoporosis’ and ‘whole-body vibration exercise’. PMID:26327887

  10. Genetic Determinants of Osteoporosis: Common Bases to Cardiovascular Diseases?

    Osteoporosis is the most common and serious age-related skeletal disorder, characterized by a low bone mass and bone microarchitectural deterioration, with a consequent increase in bone fragility and susceptibility to spontaneous fractures, and it represents a major worldwide health care problem with important implications for health care costs, morbidity and mortality. Today is well accepted that osteoporosis is a multifactorial disorder caused by the interaction between environment and genes that singularly exert modest effects on bone mass and other aspects of bone strength and fracture risk. The individuation of genetic factors responsible for osteoporosis predisposition and development is fundamental for the disease prevention and for the setting of novel therapies, before fracture occurrence. In the last decades the interest of the Scientific Community has been concentrated in the understanding the genetic bases of this disease but with controversial and/or inconclusive results. This review tries to summarize data on the most representative osteoporosis candidate genes. Moreover, since recently osteoporosis and cardiovascular diseases have shown to share common physiopathological mechanisms, this review also provides information on the current understanding of osteoporosis and cardiovascular diseases common genetic bases.

  11. Epidemiology of spinal osteoporosis.

    Melton, L J

    1997-12-15

    Approximately 30% of postmenopausal white women in the United States have osteoporosis, and 16% have osteoporosis of the lumbar spine in particular. Bone density of the spine is positively associated with greater height and weight, older age at menopause, a history of arthritis, more physical activity, moderate use of alcoholic beverages, diuretic treatment, and current estrogen replacement therapy, whereas later age at menarche and a maternal history of fracture are associated with lower levels of density. Low bone density leads to an increased risk of osteoporotic fractures. Fracture risk also increase with age. Vertebral fractures affect approximately 25% of postmenopausal women, although the exact figure depends on the definition used. Recent data show that vertebral fracture rates are as great in men as in women but, because women live longer, the lifetime risk of a vertebral fracture from age 50 onward is 16% in white women and only 5% in white men. Fracture rates are less in most nonwhite populations, but vertebral fractures are as common in Asian women as in those of European heritage. Other risk factors for vertebral fractures are less clear but include hypogonadism and secondary osteoporosis; obesity is protective of fractures as it is of bone loss. Compared with hip fractures, vertebral fractures are less disabling and less expensive, costing approximately $746 million in the United States in 1995. However, they have a substantial negative impact on the patient's function and quality of life. The adverse effects of osteoporotic fractures are likely to increase in the future with the growing number of elderly people. PMID:9431638

    A shorter life expectancy, a higher peak bone mass and the absence of distinct menopause equivalent explain the lower incidence of osteoporotic fractures in men. In contrast to women, osteoporosis in younger men is in most cases secondary. Causes such as prolonged glucocorticoid therapy, ethanol abuse, hypogonadism and gastrointestinal disorders are now well recognized. The impact of cigarette smoking, low calcium intake, vitamin D deficiency, hypercalciuria and thyrotoxicosis is more controversial but seems to constitute real risk factors for bone loss. Furthermore increased propensity to fall also plays a major role in fracture risk, particularly in alcoholic patients and in elderly men with neurologic disorders. PMID:11033475

    BACKGROUND There is currently no standard practice for the monitoring of patients receiving treatment for osteoporosis. Repeated dual-energy X-ray absorptiometry (DXA) is commonly used for monitoring treatment response, but it has its limitations. Bone turnover markers have advantages over DXA as they are non-invasive, relatively cheap and can detect changes in bone turnover rates earlier. However, they do have disadvantages, particularly high within- and between-patient variability. The ability of bone turnover markers to identify treatment non-responders and predict future fracture risk has yet to be established. OBJECTIVES We aimed to determine the clinical effectiveness, test accuracy, reliability, reproducibility and cost-effectiveness of bone turnover markers for monitoring the response to osteoporosis treatment. DATA SOURCES We searched 12 electronic databases (including MEDLINE, EMBASE, The Cochrane Library and trials registries) without language restrictions from inception to March 2012. We hand-searched three relevant journals for the 12 months prior to May 2012, and websites of five test manufacturers and the US Food and Drug Administration (FDA). Reference lists of included studies and relevant reviews were also searched. REVIEW METHODS A systematic review of test accuracy, clinical utility, reliability and reproducibility, and cost-effectiveness of two formation and two resorption bone turnover markers, in patients being treated for osteoporosis with any of bisphosphonate [alendronate (Fosamax, MSD), risedronate (Actonel, Warner Chilcott Company), zolendronate (Zometa, Novartis)], raloxifene (Evista, Eli Lilly and Company Ltd), strontium ranelate (Protelos, Servier Laboratories Ltd), denosumab (Prolia, Amgen Ltd) or teriparatide (Forsteo, Eli Lilly and Company Ltd), was undertaken according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines.

    2011-01-01

    Increasing numbers of children are being affected by low bone density and osteoporosis. Bone fractures are the main reason for hospitalization between 10 and 14 years of age and, over the past 3 decades, there has been an increase in the incidence of fractures in children. Childhood factors such as lifestyle, diet, chronic illness, and medications have a vital short-term impact on bone health and a long-term effect on the achievement of peak bone mass, with the potential for morbidity in adulthood. The primary forms of osteoporosis consist of rare inherited conditions, but the secondary forms are becoming more common given that chronically ill children are surviving longer. This subject should be of interest to pediatric dentists, because low mineral density and osteoporosis, together with drugs used to treat them (eg, bisphosphonates), may cause adverse effects in the oral cavity. Furthermore, the pediatric dentist is an important health care professional to counsel patients about healthy lifestyles that can help prevent the condition from an early age. PMID:21703077

  17. Osteoporosis, Fractures, and Diabetes

    PubMed Central

    2014-01-01

    It is well established that osteoporosis and diabetes are prevalent diseases with significant associated morbidity and mortality. Patients with diabetes mellitus have an increased risk of bone fractures. In type 1 diabetes, the risk is increased by ∼6 times and is due to low bone mass. Despite increased bone mineral density (BMD), in patients with type 2 diabetes the risk is increased (which is about twice the risk in the general population) due to the inferior quality of bone. Bone fragility in type 2 diabetes, which is not reflected by bone mineral density, depends on bone quality deterioration rather than bone mass reduction. Thus, surrogate markers and examination methods are needed to replace the insensitivity of BMD in assessing fracture risks of T2DM patients. One of these methods can be trabecular bone score. The aim of the paper is to present the present state of scientific knowledge about the osteoporosis risk in diabetic patient. The review also discusses the possibility of problematic using the study conclusions in real clinical practice. PMID:25050121

    1998-01-01

    A comparative microradiographic and histologic analysis of undecalcified bone samples was performed in men and women aged 18-98 years. These morphological methods showed that besides usual lamellar bone remodelling, all the so-called inert surfaces, namely both haversian and vascular canals as well as trabecular surfaces, were involved in weathering alterations of the superficial lamellae, resulting in eroded outlines devoid of osteoclast. These aspects, recorded in all pieces of our material, were visible from the earliest adult age and were randomly distributed. Except the grade of osteoporosis at a given age, the microradiographic and histologic aspects were similar in both aged men and women and did not allow sex distinction. These observations were consistent with the hypothesis of a particular destructive process affecting all the quiescent lamellar bone surfaces without osteoclast or cell participation. This kind of erosion, termed delitescence, could be at least partially responsible for the age-related and postmenopausal bone loss. In order to explain the increasing osteoporosis after menopause, it has been suggested that the estrogen deficiency could increase the percentage of dead osteocytes. Thereby the reduced cellular control on the bone surface could impair the remodeling process and fail to adapt the bone structure by repairing the microscopic lesions. PMID:11315966

    Since the identification of osteoporosis as a major health issue in aging populations and the subsequent development of the first treatment modalities for its management, considerable progress has been made in our understanding of the mechanisms controlling bone turnover and disease pathophysiology, thus enabling the pinpointing of new targets for intervention. This progress, along with advances in biotechnology, has rendered possible the development of ever more sophisticated treatments employing novel mechanisms of action. Denosumab, a monoclonal antibody against RANKL, approved for the treatment of postmenopausal and male osteoporosis, significantly and continuously increases bone mineral density (BMD) and maintains a low risk of vertebral, non-vertebral, and hip fractures for up to 8 years. Currently available combinations of estrogens with selective estrogen receptor modulators moderately increase BMD without causing the extra-skeletal adverse effects of each compound alone. The cathepsin K inhibitor odanacatib has recently been shown to decrease vertebral, non-vertebral, and hip fracture rates and is nearing approval. Romosozumab, an anti-sclerosin antibody, and abaloparatide, a PTH-related peptide analog, are at present in advanced stages of clinical evaluation, so far demonstrating efficaciousness together with a favorable safety profile. Several other agents are currently in earlier clinical and preclinical phases of development, including dickkopf-1 antagonists, activin A antagonists, β-arrestin analogs, calcilytics, and Src tyrosine kinase inhibitors.

    Summary Clodronate belongs to Bisphosphonates family and it has been studied especially for osteoporosis treatment, Paget’s disease, osteolytic metastases, hypercalcemia malignancy and some childhood skeletal diseases. Besides the osteoporosis treatment, it has been successfully used for treating tumoral osteolysis and for bone localization of multiple myeloma, hypercalcemia malignancy, primary hyperparathyroidism, Paget’s disease and algodystrophy. Filipponi study showed a statistically significant reduction of the incidence of vertebral fractures after 4 years of treatment with clodronate, intravenously administered at a dose of 200 mg every three weeks. Frediani study, published in 2003 on BONE, proved the clodronate efficacy in the prevention of fractures caused by glucocorticoid-induced osteoporosis (GIO). Clodronate doses of 800 mg/day per os and 100 mg i.m./week are substantially equivalent, because the oral absorption is about 1,9%. A higher efficacy on BMD was documented in various works, especially in cohorts of patients with a greater fracture risk, using higher doses (1600 mg per os). This has led to the hypothesis of using clodronate 200 mg i.m. formulation. Clodronate is an osteoporosis drug that can be assumed in different doses (100 mg i.m./week, clodronate 200 mg i.m. every 2 weeks) considering the risk band, identified by algorithms (FRAX o DeFRA), by BMD and by the presence of at least one risk factor. That means that it is possible to envisage a differentiated use of clodronate adapting the doses to the fracture risk and to the severity of pain symptoms, thus promoting a greater adherence to the therapy. To conclude clodronate is helpful in reducing fracture risk, is safe, well tolerated, and has a good rate cost/effectiveness in patients with fracture risk over 7% established with FRAX.

    Background Osteoporosis is a systemic skeletal disorder, characterized by reduced bone mass, deterioration of bone structure, increased bone fragility, and increased fracture risk. It is more frequent to find among women than men at a 4:1 ratio. Evidence suggests that to adopt changes on some life habits can prevent or delay development of osteoporosis. Several osteoporosis-risk factors have been confirmed in the US and western Europe, but in El Salvador there are neither reliable epidemiological statistics about this skeletal disorder nor studies addressing osteoporosis-risk factors in women. The aim of this study was to determinate the extent of osteoporosis knowledge, the levels of both daily calcium intake and weight-bearing physical activity, and the influence of several osteoporosis-risk factors on these variables in three age groups of Salvadorean women. Methods In this exploratory cross-sectional study, an osteoporosis knowledge assessment questionnaire incluiding a food frequency and a physical activity record section were used to collect data and it was delivered through a face-to-face interview. A convenience sample (n = 197) comprised of three groups of women aged 25–35 years, 36–49 years, and over 49 years was taken. Among-group comparisons of means were analyzed by two-way ANOVA. To determinate the overall influence of osteoporosis-risk factors, the multivariate analysis was used. Results Study results indicated that better educated women had more knowledge about osteoporosis than women with a low education level, regardless of age, even though this knowledge was rather fair. Older women got more weight-bearing physical activity at home and less at place of employment than reported by the younger women; however, neither group performed sufficient high-intensity WBPA to improve bone mass. Regardless of age, the most women consumed 60% or less than the Dietary Reference Intake of calcium and depend on household income, lactose intolerance and coffee

    BACKGROUND: More than one million Americans suffer osteoporotic fractures yearly, resulting in a marked increase in morbidity and mortality. Despite a decrease in bone mineral density with increasing age in all ethnic groups and both genders, preventative and therapeutics efforts in osteoporosis have been focused on caucasian and Asian women. This study assesses the osteoporosis screening practices and the frequency of low bone density in a primarily African-American population of older women. METHODS: Medical records of 252 women at risk for osteoporosis were reviewed for the diagnosis of osteoporosis, prior osteoporosis screening, prior breast cancer screening, and the use of calcium, vitamin D or estrogen. Subsequently, 128 women were assessed for risk factors for osteoporosis, and their bone mineral density was measured using a peripheral bone densitometer. RESULTS: Osteoporosis screening had been performed in 11.5% of the subjects. Of the women evaluated by peripheral bone densitometry, 44.5% of all women, 40.4% of African-American women, and 53.3% of caucasian women had abnormally low bone density measurements. The frequency of abnormal bone density increased with both increasing age and decreasing body mass index. CONCLUSIONS: Although few women in this population were previously screened for osteoporosis, low bone density occurred in African-American women at substantial rates. Increasing age and low body mass are important risk factors for low bone density in African-American women. Ethnicity should not be used as an exclusion criterion for screening for osteoporosis.

    Thyroid hormones play the essential role in the regulation of metabolism and bone remodeling in physiological conditions and in the course of thyroid dysfunction. Introduction of densitometry to the diagnostics of osteoporosis has made possible the evaluation of influence of both hyperthyroidism and hypothyroidism and their treatment on bone mineral density. Moreover it became possible to estimate the influence of treatment with exogenous thyroid hormones on the skeletal system. Authors presented mechanisms of the thyroid hormones action on bone tissue and analysed current state of knowledge concerning the influence of the thyroxine treatment with replacement and suppressive doses on the bone mineral density. The influence of thyroid hormones on the skeletal system with respect to premenopausal and postmenopausal period was also discussed. Great discrepancies in literature data and its reasons were underlined. PMID:16335687

    Background Osteoporosis one of the most serious disease to decrease the quality of life and cause economic loss. Thus, prevention of osteoporosis has become an important health concern. The study examined in adherence to osteoporosis guidelines and compared the levels of adherence to osteoporosis guidelines between bone health status in Korean adult. Methods This study used data from a nationally represented sample of Koreans (n=3,419) from 2008 to 2011 Korea National Health and Nutrition Examination Survey. We were divided into three groups by T-score: normal, osteopenia and osteoporosis. Assessment of adherence level was based on 5 components of osteoporosis guidelines, considering intake of sodium, calcium and protein, smoking and regular exercise. Results The sex, body mass index, income and educational level did not significantly differ between three groups. Deficient intake of calcium was significantly associated with a threefold greater odds in osteoporosis group (OR 3.6; 95% confidence interval [CI] 2.52-5.22). Excessive protein intake was significantly increased the risk only in osteoporosis group compared to the normal group (OR 1.71; 95% CI 1.15-2.62). Smoking increased the risk in osteoporosis group compared to the normal group (OR 2.88; 95% CI 1.75-4.76), osteoporosis group compared to the osteopenia group (OR 2.69; 95% CI 1.61-4.55). Conclusions Nutritional factor (intake of calcium and protein) and lifestyle-related factor (smoking and exercise) must be accompanied the management for bone health. An adherence of guidelines is considered very important for the prevention of osteoporosis. PMID:27622178

    Considerable progress in the development of methods for assessing the skeleton now makes it possible to detect osteoporosis non-invasively and early. There is a variety of techniques available at present: single-photon (SPA) and single X-ray absorptiometry (SXA), dual-photon (DPA) and dual X-ray absorptiometry (DXA), quantitative computed tomography (QCT), radiographic absorptiometry (RA), and quantitative ultrasound (QUS), and their development has certainly been driven by the need to overcome the inherent shortcomings of plain radiography for this purpose. Both SPA and SXA methods make a quantitative assessment of the bone mineral content (BMC) or density (BMD) at peripheral sites of the skeleton possible. Single energy measurements are not possible at sites with variable soft tissue thickness and composition, i.e., the axial skeleton. For these purposes, DPA and DXA techniques were introduced. The main advantages of an X-ray system over a radionuclide system are shortened examination time, greater accuracy and precision limited to higher resolution, and removal of errors due to source decay correction. Low radiation dose, availability, capacity to evaluate multiple sites, and ease of use have made DXA the most widely used technique for measuring bone mineral density. QCT can determine the true volumetric density of trabecular or cortical bone in three dimensions at any skeletal site. Recently developed new computer-assisted methods have improved RA precision, thus providing a simple and inexpensive technique for screening of bone mineral status of large populations. QUS was reported to provide information regarding the structural characteristics of bone, which may be relevant to the appearance of osteoporotic fractures; indeed, some studies suggest a relationship between QUS and bone strength beyond that which can be explained by BMD. Recent experimental studies suggested that magnetic resonance might also constitute a promising tool for assessing osteoporosis

    Drug-induced osteoporosis is a significant health problem and many physicians are unaware that many commonly prescribed medications contribute to significant bone loss and fractures. In addition to glucocorticoids, proton pump inhibitors, selective serotonin receptor inhibitors, thiazolidinediones, anticonvulsants, medroxyprogesterone acetate, aromatase inhibitors, androgen deprivation therapy, heparin, calcineurin inhibitors, and some chemotherapies have deleterious effects on bone health. Furthermore, many patients are treated with combinations of these medications, possibly compounding the harmful effects of these drugs.

Using the method of absorption spectrophotometry, they found a reduced level of Mg in red blood cells in 63.6% of senile, 66.7% postmenopausal and only in 22.2% drug-induced osteoporoses. Also the mean level of red cell magnesium was significantly lower in the group of senile (1.94 mmol) and postmenopausal (1.85 mmol) osteoporosis as compared with drug-induced osteoporosis (2.25 mmol). The authors revealed moreover that the level of red cell magnesium in the former two groups declines in proportion to the severity of osteoporosis and correlates thus with the clinical and X-ray finding. For treatment of osteoporisis the authors used magnesium lactate alone (in 37 patients) and combined with sodium fluoride (in 23 patients). In the majority of patients they had very favourable results. Based on laboratory and therapeutic results, consistent with data in the experimental literature, the authors assume that magnesium as a catalyst of bone metabolism and as one of the most important factors controlling the formation of bone matrix and its mineralization plays a significant role in the aetiopathogenesis of senile and postmenopausal osteoporosis. The authors assume that Mg deficiency which is increasing in recent years in soil as well as in foodstuffs and water may be the main cause of the increasing number of patients with osteoporosis in civilized countries. Magnesium should have its firm place not only in therapy but also in prevention of the majority of osteoporosis. PMID:2750424

    Objectives The prevalence of osteoporosis and related fractures has increased rapidly in Korean women. Proper nutrition intake is associated with the prevention of osteoporosis. We analyzed the association between dietary patterns and the risk of osteoporosis during a 4-year follow-up in postmenopausal Korean women. Methods Postmenopausal women (n = 1,725) who participated in the Korean Genome and Epidemiology Study were enrolled. Food intake was assessed using a validated semiquantitative food frequency questionnaire, and a quantitative ultrasound device was used to measure the speed of sound at the radius and tibia. Results Three major dietary patterns were identified using factor analysis based on baseline intake data: traditional (high intake of rice, kimchi, and vegetables), dairy (high intake of milk, dairy products, and green tea), and western (high intake of sugar, fat, and bread). Multivariate Cox proportional hazards models were used to estimate relative risk for osteoporosis. An inverse association was detected between the dairy dietary pattern and the osteoporosis incidence [relative risk (RR): 0.63, 95% confidence interval (CI): 0.42–0.93, p-trend=0.055 in radius; RR: 0.56, 95% CI: 0.35–0.90, p-trend=0.048 in tibia]. Individuals in the highest quintile for the traditional dietary pattern (p-trend = 0.009 in tibia) and western dietary pattern (p-trend = 0.043 in radius) demonstrated a higher risk of osteoporosis incidence than those in the lowest quintile. Conclusion These results suggested that high consumption of milk, dairy products, and green tea may reduce the risk of osteoporosis in postmenopausal Korean women. PMID:24159515

    Osteoporosis is one of the major problems facing women and older people of both sexes. The morbid event in osteoporosis is fracture. However, the definition of osteoporosis should not require the presence of fractures but only a decrease in bone mass that is associated with an unacceptably high risk of fracture. In the USA, approximately 1.5 million fractures annually are attributable to osteoporosis: these include 700,000 vertebral fractures, 250,000 distal forearm (Colles') fractures, 250,000 hip fractures, and 300,000 fractures of other limb sites. The lifetime risk of fractures of the spine (symptomatic), hip, and distal radius is 40% for white women and 13% for white men from 50 years of age onwards. Following a hip fracture, there is a 10%-20% mortality over the subsequent 6 months, 50% of sufferers will be unable to walk without assistance, and 25% will require long-term domiciliary care. Contrary to prevailing opinion, the morbidity and suffering associated with wrist and spine fractures are also considerable. The annual cost of osteoporosis to the US healthcare system is at least $5-$10 billion with similar incidence and cost in other developed countries. These already high costs will increase further with continued aging of the population. In addition, the population explosion in underdeveloped countries will change the demography of osteoporosis; for example, the incidence of hip fracture, and, presumably, other osteoporotic fractures will increase four-fold worldwide during the next 50 years and the attendant costs will threaten the viability of the healthcare systems of many countries. Unless decisive steps for preventive intervention are taken now, a catastrophic global epidemic of osteoporosis seems inevitable. PMID:8573428

Urolithiasis and osteoporosis are two multifactorial diseases which are evidently reciprocal. This is why we suggest that educating the population about the risk factors for occurrence of these diseases as well as preventive measures that may contribute to their decrease should begin as early as possible.

    Osteoporosis affects 1.2 million Australians and, in 2012, fractures due to osteoporosis and osteopenia in Australians aged over 50 years cost $2.75 billion. Even minor minimal trauma fractures are associated with increased morbidity and mortality. Despite increasing therapeutic options for managing osteoporosis, fewer than 20% of patients with a minimal trauma fracture are treated or investigated for osteoporosis, so under-treatment is extremely common. Fracture risk assessment is important for selecting patients who require specific anti-osteoporosis therapy. Post-menopausal osteoporosis is frequently due to an imbalance in bone remodelling, with bone resorption exceeding bone formation. Antiresorptive drugs reduce the number, activity and lifespan of osteoclasts, and include bisphosphonates, oestrogen, selective oestrogen receptor-modulating drugs, strontium ranelate, and the human monoclonal antibody denosumab. Teriparatide is the only anabolic agent currently available that stimulates osteoblast recruitment and activity; its antifracture efficacy for non-vertebral fractures increases with the duration of therapy for up to 2 years when it is associated with persisting increases in bone formation rate at the tissue level. Newer anabolic agents are imminent and include an analogue of parathyroid hormone-related protein, abaloparatide, and a humanised monoclonal antibody to an inhibitor of bone formation, romosozumab. Selection of anti-osteoporosis therapy should be individualised to patients, and the duration of bisphosphonate therapy has been covered in recent guidelines. The benefits of treatment far outweigh any risks associated with long term treatment. General practitioners need to take up the challenge imposed by osteoporosis and become champions of change to close the evidence-treatment gap. PMID:27510350

    Due to older people's low sports participation rates, exercise frequency may be the most critical component for designing exercise protocols that address bone. The aims of the present article were to determine the independent effect of exercise frequency (ExFreq) and its corresponding changes on bone mineral density (BMD) and to identify the minimum effective dose that just relevantly affects bone. Based on the 16-year follow-up of the intense, consistently supervised Erlangen Fitness and Osteoporosis Prevention-Study, ExFreq was retrospectively determined in the exercise-group of 55 initially early-postmenopausal females with osteopenia. Linear mixed-effect regression analysis was conducted to determine the independent effect of ExFreq on BMD changes at lumbar spine and total hip. Minimum effective dose of ExFreq based on BMD changes less than the 90% quantile of the sedentary control-group (n=43). Cut-offs were determined after 4, 8, 12 and 16years using bootstrap with 5000 replications. After 16years, average ExFreq ranged between 1.02 and 2.96sessions/week (2.28±0.40sessions/week). ExFreq has an independent effect on LS-BMD (p<.001) and hip-BMD (p=.005) changes. Bootstrap analysis detected a minimum effective dose at about 2sessions/week/16years (cut-off LS-BMD: 2.11, 95% CI: 2.06-2.12; total hip-BMD: 2.22, 95% CI: 2.00-2.78sessions/week/16years). In summary, the minimum effective dose of exercise frequency that relevantly addresses BMD is quite high, at least compared with the low sport participation rate of older adults. This result might not be generalizable across all exercise types, protocols and cohorts, but it does indicate at least that even when applying high impact/high intensity programs, exercise frequency and its maintenance play a key role in bone adaptation.

    Osteoporosis is of medical interest only because it increases bone fragility and risk of fracture, and except for relief of symptoms, preventing fracture is the only purpose of intervention. To prevent the first fracture, adequate bone density must be accumulated and conserved, but to prevent subsequent fracture, bone density must be augmented so that the supportive function of the skeleton can be restored. Almost 50 years after the recognition of post menopausal osteoporosis as a clinical entity, not one of the many treatments that have been used has been demonstrated to be efficacious in reducing subsequent fracture risk. My purpose is not to recite this chronicle of disappointment, but to account for it in terms of bone biology, to consider some possible exceptions, and to reiterate the importance of preventing damage to the skeleton rather than belatedly attempting its repair.

    2015-12-01

    Osteoporosis, the most common metabolic skeletal disease, is characterized by decreased bone mass and deteriorated bone quality, leading to increased fracture risk. With the aging of the population, osteoporotic fracture is an important public health issue. Organisms are constantly exposed to various stressful stimuli that affect physiological processes. Recent studies showed that chronic psychological stress is a risk factor for osteoporosis by various signaling pathways. The purpose of this article is to review the recent progress of the association between chronic psychological stress and osteoporosis. Increasing evidence confirms the physiological importance of the central nervous system, especially the hypothalamus, in the regulation of bone metabolism. Both animal and human studies indicate that chronic psychological stress induces a decrease of bone mass and deterioration of bone quality by influencing the hypothalamic-pituitary-adrenocortical (HPA) axis, sympathetic nervous system, and other endocrine, immune factors. Active mastication, proven to be an effective stress-coping behavior, can attenuate stress-induced neuroendocrine responses and ameliorate stress-induced bone loss. Therefore, active mastication may represent a useful approach in preventing and/or treating chronic stress-associated osteoporosis. We also discuss several potential mechanisms involved in the interaction between chronic stress, mastication and osteoporosis. Chronic stress activates the HPA axis and sympathetic nervous system, suppresses the secretion of gonadal hormone and growth hormone, and increases inflammatory cytokines, eventually leading to bone loss by inhibiting bone formation and stimulating bone resorption.

    The aim of this study was to examine women's attitudes and health beliefs towards osteoporosis screening in a community pharmacy setting, utilizing the theoretical framework of Health Belief Model. A nonexperimental, cross-sectional research design, examining a convenience sample of women aged 18 and over, from several New York City senior care centers, a church, and a university campus in New York, was employed to assess the study objectives. Osteoporosis Health Belief Scale questionnaire was used to study the attitudes and health beliefs of participants towards bone mineral density screening in community pharmacy. From the study, it was observed that perceptions of severity and susceptibility towards osteoporosis and subjects' demographic characteristics did not seem to significantly influence the decision to screen in a community pharmacy setting. The perceptions of benefits of community pharmacy-based osteoporosis screening and the perceived barriers were found to be of greater importance in women's decisions to engage in osteoporosis-specific preventive behavior.

    Background For women living with osteoporosis, high out-of-pocket drug costs may prevent drug therapy initiation. We investigate the association between oral osteoporosis out-of-pocket medication costs and female Medicare beneficiaries’ initiation of osteoporosis drug therapy. Methods We used 2007 and 2008 administrative claims and enrollment data for a 5% random sample of Medicare beneficiaries. Our study sample included age-qualified, female beneficiaries who had no prior history of osteoporosis but were diagnosed with osteoporosis in 2007 or 2008. Additionally, we only included beneficiaries continuously enrolled in standalone prescription drug plans. We excluded beneficiaries who had a chronic condition that was contraindicated with osteoporosis drug utilization. Our final sample included 25,069 beneficiaries. Logistic regression analysis was used to examine the association between the out-of-pocket costs and initiation of oral osteoporosis drug therapy during the year of diagnosis. Findings Twenty-six percent of female Medicare beneficiaries newly diagnosed with osteoporosis initiated oral osteoporosis drug therapy. Beneficiaries’ out-of-pocket costs were not associated with the initiation of drug therapy for osteoporosis. However, there were statistically significant racial disparities in beneficiaries’ initiation of drug therapy. African Americans were 3 percentage points less likely to initiate drug therapy than whites. In contrast, Asian/Pacific Islander and Hispanic beneficiaries were 8 and 18 percentage points respectively more likely to initiate drug therapy than whites. Additionally, institutionalized beneficiaries were 11 percentage points less likely to initiate drug therapy than other beneficiaries. Conclusions Access barriers for drug therapy initiation may be driven by factors other than patients’ out-of-pocket costs. These results suggest that improved osteoporosis treatment requires a more comprehensive approach that goes beyond payment

    Bone differs from other tissues in its capacity to self-repair after a fracture. The low bone mass and structural deterioration of bone associated with osteoporosis increases the risk of fragility fracture compared with healthy individuals. The intention of this article is to review the complex process of fracture repair and essential requirements for a successful fracture healing response summarized as the "diamond concept" in terms of aging and osteoporosis. The current preclinical and clinical evidence for a beneficial or harmful influence of anti-osteoporosis medications such as bisphosphonates, parathyroid hormone (PTH), strontium ranelate and antibodies of Wnt-inhibiting signaling proteins on bone healing is presented and discussed. Literature suggests that there are no detrimental consequences of such therapeutics on fracture repair processes. Following a fragility fracture, it seems that early start of preventive anti-osteoporotic treatment right after surgery does not delay the union of the fracture, except perhaps in the case of very rigidly fixed fracture requiring direct bone healing. There is some promising experimental and clinical evidence for possible enhancement of the bone repair process via administration of systemic agents. Further well designed studies in humans are necessary to accumulate more evidence on the positive effects and to translate this knowledge into valid therapeutic applications. PMID:26768282

    Osteoporosis is a disease that affects the bones. It leads to increased risk of fractures as a result of decreased bone mineral density. The goal of this study was to assess the general perception of osteoporosis as well as knowledge of lifestyle, risk factors, and preventive measures among patients in Qatar. The study was conducted between September 2013 and September 2014. The study subjects (n = 93) were patients diagnosed with osteoporosis who attended the Outpatient Rheumatology Clinic at Hamad General Hospital in Doha, Qatar. The results showed that those with a university or graduate degree had a significantly higher level of knowledge about osteoporosis (p = 0.009) than those with less education. Among those in our study, knowledge related to osteoporosis was principally obtained through media sources such as television and radio (39%). In conclusion, osteoporosis patients in Qatar need a better understanding of the disease. Identifying thought patterns related to the perception of osteoporosis and treatment might assist in building a foundation for management modalities and effective preventive strategies for the disease in Qatar.

    As the increase in lifespan brings to light diseases that were previously not clinically detectable, osteoporosis has become an issue of worldwide significance. The disease is marked by a loss of bone mass; the bones become less dense, fragile and more prone to fracturing. Because it is regulated by endocrine and environmental factors, osteoporosis presents a multifactorial etiopathogenesis, with the genetic component accounting for 70% of an individual variation in bone mass density (BMD), the principal determinant, with age, of fracture risk. Pathological conditions such as celiac disease (CD) exacerbate the process of bone loss, so that the occurrence of osteoporosis in celiac subjects is of particular note: indeed, the screening of osteoporosis patients for this disease is advisable, since it may be the only sign of undiagnosed CD. An increase in interleukin IL-1β, of the IL-1 system, in the relatives of celiac patients confirms the genetic predisposition to osteoporosis and its presence is evidence of an association between the two conditions. The direct effect on the bones of CD is secondary to poor absorption of calcium and vitamin D. In women osteoporosis is indirectly associated with early menopause and amenorrhea, and it may follow prolonged breast-feeding and frequent pregnancies, while in men it is associated with hypogonadism and GH deficit. These endocrine and non-endocrine factors exert their effects on bones by modulating the RANK/RANK-L/OPG system. An appropriate lifestyle from adolescence onwards, together with early diagnosis of and treatment for CD and primary and secondary endocrine pathologies are important for the prevention of damage to the bones.

    Osteoporosis is a common condition characterised by low bone mineral density (BMD) and an increased risk of fragility fractures. It affects up to 30% of women and 12% of men at some point in their lives. Two of the most important risk factors are increasing age and female gender, although other common and potentially modifiable risk factors include long-term corticosteroid therapy, chronic inflammatory disease, malabsorption and untreated premature menopause. The diagnosis of osteoporosis can be confirmed by DEXA but this should only be performed in patients who have an increased risk of fracture on the basis of clinical risk factors. DEXA should be considered if the 10-year risk of major osteoporotic fracture is > 10%. If the BMD T-score values by DEXA at the lumbar spine, femoral neck or total hip are at or below -2.5 then the diagnosis of osteoporosis is confirmed. Vertebral fractures are generally taken as diagnostic of osteoporosis, even if spine BMD values are not in the osteoporotic range. Oral bisphosphonates are the first-line treatment. If they are contraindicated or not tolerated then parenteral therapy should be considered. There is evidence that fractures occur in glucocorticoid-induced osteoporosis at higher levels of BMD than in postmenopausal osteoporosis so therapy should be considered in patients with a BMD T-score of <-1.5. Although it is useful to have a DEXA scan before starting treatment to provide a baseline value to assess response, this investigation is not absolutely necessary to initiate bone protective therapy, especially in those aged above 65 since the vast majority of these patients will have a T-score of -1.5 or below. In younger individuals where BMD is likely to be higher DEXA is useful in determining if bone protective treatment is needed immediately or if it could be delayed until the T score falls below -1.5.

    are also applied to the patients with osteoporosis. Therefore, a reasonable advice is to consider pharmacological treatment for osteoporosis in those UC patients who already present fragility fractures, which bring a high risk of subsequent fractures. Therapy has also to be considered in patients with a high risk of fracture even if it did not yet happen, and particularly when they had long periods of corticosteroid therapy or cumulative high dosages. In patients without fragility fractures or steroid treatment, a medical decision about treatment could be guided by the FRAX tool to determine the intervention threshold. Among drugs for osteoporosis treatment, the bisphosphonates are the most studied ones, with the best and longest evidence of efficacy and safety. Despite this, several questions are still open, such as the duration of treatment, the necessity to discontinue it, the indication of therapy in young patients, particularly in those without previous fractures. Further, it has to be mentioned that a long-term bisphosphonates use in primary osteoporosis has been associated with an increased incidence of dramatic side-effects, even if uncommon, like osteonecrosis of the jaw and atypical sub-trochanteric and diaphyseal femoral fractures. UC is a long-lasting disease and the majority of patients is relatively young. In this scenario primary prevention of fragility fracture is the best cost-effective strategy. Vitamin D supplementation, adequate calcium intake, suitable physical activity (when possible), removing of risk factors for osteoporosis like smoking, and avoiding falling are the best medical acts.

    Efficient therapies are available for the treatment of osteoporosis, however, there are still unmet needs. Anti-resorptive therapies only increase bone mineral density to a certain extent and reduce the risk of non-vertebral fractures by 20%, only one anabolic option is available-the effect of which levels off over time, and the evidence for combination therapy targeting both resorption and formation is limited. The current review will focus on emerging treatments of osteoporosis with the potential of enhanced anabolic effects (romosozumab and abaloparatide) or uncoupling of resorption and formation (odanacatib and romosozumab) as well as the effect of combination therapy.

Options All aspects of osteoporosis care and its fracture complications — including classification, diagnosis, management and methods for screening, as well as prevention and reducing fracture risk — were reviewed, revised as required and expressed as a set of recommendations. Outcomes Strategies for identifying and evaluating those at high risk; the use of bone mineral density and biochemical markers in diagnosis and assessing response to management; recommendations regarding nutrition and physical activity; and the selection of pharmacologic therapy for the prevention and management of osteoporosis in men and women and for osteoporosis resulting from glucocorticoid treatment. Evidence All recommendations were developed using a justifiable and reproducible process involving an explicit method for the evaluation and citation of supporting evidence. Values All recommendations were reviewed by members of the Scientific Advisory Council of the Osteoporosis Society of Canada, an expert steering committee and others, including family physicians, dietitians, therapists and representatives of various medical specialties involved in osteoporosis care (geriatric medicine, rheumatology, endocrinology, obstetrics and gynecology, nephrology, radiology) as well as methodologists from across Canada.

    Lysinuric protein intolerance (LPI) is an autosomal recessive disease characterized by defective transport of cationic amino acids. Patients have an increased incidence of fractures and their skeletal radiographs show osteoporosis. The aim of the study was to characterize the osteopenia in LPI. Twenty-nine Finnish LPI patients (age range 3.7-44.4 years) were screened for parameters of bone metabolism. Morphometric analysis of bone was carried out in specimens of 9 patients. Collagen synthesis was studied with cultured skin fibroblasts (4 patients) and collagen fibril sizes (3 patients) were measured using electron microscopy. Most histological bone specimens (8/9) showed osteoporosis. Osteomalacia was excluded. Routine clinical laboratory tests were unrevealing. The concentrations of free hydroxyproline and type III procollagen N-propeptide in serum and the urinary excretion of hydroxyproline were increased in almost all patients during their growth and in about half of adult patients. Collagen synthesis in LPI fibroblast cultures was significantly decreased compared with that in age-matched controls at 5 (p < 0.01), 14 (p < 0.01) and still at 30 years (p < 0.01), whereas no difference was observed at the age of 44 years (p = N.S.). Osteoporosis in LPI might reflect defective matrix protein synthesis caused by protein deprivation and deficiency of cationic amino acids. Increased collagen turnover can also contribute to the osteoporosis. PMID:8412005

Here, we investigated the potential of using risedronate/zinc-hydroxyapatite (ZnHA) nanoparticles based formulation in a rat model of experimental osteoporosis. Risedronate, a targeting moiety that has a strong affinity for bone, was loaded to ZnHA nanoparticles by adsorption method. Prepared risedronate/ZnHA drug formulation was characterized by field-emission scanning electron microscopy, X-ray diffraction analysis and fourier transform infrared spectroscopy. In vivo performance of the prepared risedronate/ZnHA nanoparticles was tested in an experimental model of postmenopausal osteoporosis. Therapy with risedronate/ZnHA drug formulation prevented increase in serum levels of bone-specific alkaline phosphatase and tartrate-resistant acid phosphatase 5b better than risedronate/HA or risedronate. With respect to improvement in the mechanical strength of the femoral mid-shaft and correction of increase in urine calcium and creatinine levels, the therapy with risedronate/ZnHA drug formulation was more effective than risedronate/HA or risedronate therapy. Moreover, risedronate/ZnHA drug therapy preserved the cortical and trabecular bone microarchitecture better than risedronate/HA or risedronate therapy. Furthermore, risedronate/ZnHA drug formulation showed higher values of calcium/phosphorous ratio and zinc content. The results strongly implicate that risedronate/ZnHA drug formulation has a therapeutic advantage over risedronate or risedronate/HA therapy for the treatment of osteoporosis. PMID:27040198

    Background The Osteoporosis Health Belief Scale (OHBS) is a 42-item questionnaire designed to assess susceptibility, seriousness, calcium benefits, calcium barriers, exercise benefits, exercise barriers, and health motivation related to osteoporosis. We aimed to evaluate its psychometric properties to enable the provision of educational tips regarding osteoporosis. Methods All women who had visited the department of obstetrics and gynecology (OBGYN) and whose bone mineral density was measured from January 2010 to December 2011 were enrolled by interview using the OHBS. We also evaluated the women's general clinical characteristics. Results One hundred seventy-seven women were enrolled in the present study. In the present study, the barriers to calcium intake subscale had the lowest mean score (15.03±3.02), and the Benefit of Exercise subscale had the highest (23.02±3.03). The scores for participants in their 20s were significantly higher than scores for those in their 70s on the Benefits of Exercise subscale and Barriers to Exercise subscale (P=0.014 and P=0.022, respectively). Conclusions Education for health motivation to prevent osteoporosis is important for young women. Additional systematic education programs are needed for the general population. PMID:24524052

    Bone pain is one of the most frequent kinds of chronic pain, mainly in elderly patients. It causes a significant worsening of functional capacity and deterioration in the quality of life in people affected. Mechanisms of pain in osteoporosis are poorly known and often extrapolated by other pathologies or other experimental model. One of principal causes would be a "hyper-remodeling" of bone, that involves osteoclasts activity and pathological modifications of bone innervation. Several studies show that osteoclasts play a significant role in bone pain etiology. Pain in osteoporosis is mainly nociceptive, if it become persistent a sensitization of peripheral and central nervous system can occur, so underlining the transition to a chronic pain syndrome. Central sensitization mechanisms are complex and involve several neuromediators and receptors (Substance P, NMDA, etc.). Most common manifestations of osteoporosis are vertebral compression fractures that cause persistent pain, though to differentiate from pain originating in structures as joint or muscle. First manifestation can be an acute pain due to pathological fracture, those of hip often causes disability. Pain in osteoporosis is an important clinical challenge. Often its complications and consequences on patient quality of life are underestimated with not negligible social implications. A balanced and early multimodal pain therapy including opioids as necessary, even in cases of acute pain, improve the functional capacity of patients and helps to prevent neurological alterations that seems to contribute in significant way in causing irreversible pain chronic syndromes.

    Mechanism of generalized osteoporosis associated with rheumatoid arthritis(RA)is multifactorial and following factors has been proposed:systemic effect of RA synovitis, glucocorticoids, weight loss, and endocrine changes. In addition to control of RA inflammation and management of glucocorticoid-induced osteoporosis(GIO), antiresorptive therapy, such as bisphosphonates is expected to show efficacy. Recently, anti-RANKL monoclonal antibodies have been shown to inhibit bone erosion and bone loss in combination with methotrexate in RA. GC-induced bone loss is most rapid during the initial 3 ~ 6 months and more slowly thereafter. Therefore, both primary and secondary prevention are important. The Japanese Society for Bone and Mineral Research(JSBMR)has updated the Guidelines on the Management and Treatment of GIO and has incorporated a new scoring method. By analyzing five GIO cohorts from primary and secondary prevention studies, age, GC dose, lumbar BMD, and prior fragility fractures were identified as risk factors and the fracture risk for an individual can be calculated as the sum of the scores for each risk factor. Pharmacological intervention should be started on the basis of a score of 3 as the optimal cut-off score. Both alendronate and risedronate are recommended as first-line treatment. Ibandronate,teriparatide, and active vitamin D3 derivatives are recommended as alternative option. PMID:26608858

    The combination of calcium with vitamin D (vitamin D(3) [colecalciferol]) forms the basis of preventive and therapeutic regimens for osteoporosis. A number of studies have suggested that the combination of calcium and vitamin D is effective when administered at respective dosages of at least 1200 mg and 800 IU per day, although efficacy is, as expected, affected by patient compliance. Overall, treatment with this combination appears to be effective in reducing the incidence of non-vertebral and hip fractures. Also, in all drug studies (of antiresorptive and anabolic agents and strontium ranelate) that demonstrated a reduction in risk of osteoporotic fractures, patients also took calcium and vitamin D supplements. An important finding in this regard is that vitamin D levels have been demonstrated to be inadequate in more than half of women treated for osteoporosis in the US and Europe. The capacity of the small intestine to absorb calcium salts depends on the solubility and ionization of the salts. These properties vary for different salts, with fasting calcium citrate absorption being greater than that of calcium lactogluconate and calcium carbonate. Calcium citrate formulations taken between meals may help to prevent abdominal distension and flatulence, as well as minimize the risk of renal calculus formation, thus helping to optimize patient compliance. Therefore, calcium citrate combined with vitamin D is the combination of choice for the prevention or treatment of osteoporosis. PMID:21405146

    Purpose While current osteoporosis management guidelines recommend use of pharmacologic treatment following hip fracture, the care of such patients has been suboptimal. The objective of this cross-national study is to quantify the use of and adherence to osteoporosis medication following hip fracture in three countries with different health care systems- the United States, Korea and Spain. Methods In three cohorts of patients aged ≥65 years hospitalized for hip fracture, we calculated the proportion receiving ≥1 osteoporosis drug after discharge. Adherence to osteoporosis treatment was measured as the proportion of days covered (PDC) during the first year following the hip fracture. Results We identified 86,202 patients with a hip fracture - 4,704 (U.S. Medicare), 6,700 (U.S. commercial), 57,631(Korea), and 17,167 (Spain). The mean age was 77–83 years and 74–78% were women. In the year prior to the index hip fracture, 16–18% were taking an osteoporosis medication. Within 3 months following the index hip fracture, 11% (U.S. Medicare), 13% (U.S. commercial), 39% (Korea), and 25% (Spain) of patients filled ≥1 prescription for osteoporosis medication. For those who filled one or more prescriptions for an osteoporosis medication, the mean PDC in the year following the fracture was 0.70 (U.S. Medicare), 0.67 (U.S. commercial), 0.43 (Korea) and 0.66 (Spain). Conclusions Regardless of differences in health care delivery systems and medication reimbursement plans, the use of osteoporosis medications for the secondary prevention of osteoporotic fracture was low. Adherence to osteoporosis treatment was also suboptimal with the PDC<0.70 in all three countries. PMID:25660252

    Skeletons have significant bone loss (osteoporosis) under microgravity environment. This study showed that microbial polyhydroxyalkanoates (PHA) degradation product, and also ketone body 3-hydroxybutyrate acid (3HB) and its derivative 3-hydroxybutyrate methyl ester (3HBME) inhibit the development of osteoporosis in mice maintained under simulated microgravity, helping preserve bone microstructure and mechanical property. Mice orally administrated with 3HB or 3HBME recovered much more quickly from osteoporosis resulted from simulated microgravity compared with the controls without 3HB or 3HBME treatments due to less calcium loss to the sera. It was known that abnormal activation of osteoclasts induced by microgravity led to bone tissue absorption and thus osteoporosis. In this study, it was found that 3HB or 3HBME down-regulated the nuclear factor of activated T-cells cytoplasmic 1 (NFATc1), which is the transcription factor of pre-osteoclast differentiation. When NFATc1 activation and downstream functions were inhibited, 3HB or 3HBME was able to strongly reduce pre-osteoclast differentiation. As a result, bone absorption was prevented. It was demonstrated that 100 mg/kg 3HB resulted in the most obvious effect on osteoporosis prevention. Based on these results, 3HB and 3HBME should be further developed as novel drug candidates against osteoporosis induced by microgravity. PMID:24976243

    Introduction Osteoporosis is still a under recognized entity in the population. Osteoporosis-related fractures can be prevented if people at risk can be screened, diagnosed and treated early. Bisphosphonates remain the mainstay of osteoporosis treatment as they have multimodal action. Oral bisphosphonate therapy has, significant gastrointestinal side effects leading to noncompliance. Of late parenteral Zoledronic Acid is being used as once or twice yearly infusion for the treatment of osteoporosis. Aim Our article studies the side effect profile and tolerability of parenteral Zoledronic Acid, one of the most potent bisphosphonate used in clinical practice in patients with osteoporosis. Materials and Methods This study was done in KMC hospitals where 49 patients diagnosed with osteoporosis were included for the study. After obtaining a written informed consent each patient received one infusion of 5 mg Zoledronic Acid as per standard treatment protocol. Patient was monitored for clinical improvement and development of any adverse effects. Conclusion In our study all subjects reported significant pain relief after infusion of Zoledronic Acid. Zoledronic Acid had very few serious adverse effects that can be prevented through pre-infusion screening, maintaining good hydration and careful patient monitoring. In our population the patients only experienced mild symptoms of pyrexia, arthralgia myalgia and influenza like symptoms which resolved with symptomatic treatment. PMID:26894105

    Treatment of osteoporosis is aimed to prevent fragility fractures and to stabilize or increase bone mineral density. Several drugs with different efficacy and safety profiles are available. The long-term therapeutic strategy should be planned, and the initial treatment should be selected according to the individual site-specific fracture risk and the need to give the maximal protection when the fracture risk is highest (i.e. in the late life). The present consensus focused on the strategies for the treatment of postmenopausal osteoporosis taking into consideration all the drugs available for this purpose. A short revision of the literature about treatment of secondary osteoporosis due both to androgen deprivation therapy for prostate cancer and to aromatase inhibitors for breast cancer was also performed. Also premenopausal females and males with osteoporosis are frequently seen in endocrine settings. Finally particular attention was paid to the tailoring of treatment as well as to its duration.

    Patients of osteoporosis are comprised of about 11 million people in Japan and it is one of the problems that have gained society. For preventing the osteoporosis, obtaining early detection and treatment are necessary. Multi-slice CT technology has been improving for three dimensional (3D) image analysis, higher body axis resolution and shorter scan time. 3D image analysis using multi-slice CT images of thoracic vertebra can be used for supporting diagnosis of osteoporosis. Simultaneously, this analysis can be used for lung cancer diagnosis which may lead to early detection. We develop automatic extraction and partitioning algorithm for spinal column by analyzing vertebral body structure, and the analysis algorithm of the vertebral body using shape analysis and a bone density measurement for the diagnosis of osteoporosis. An effective result was provided for the case including an insufficient complicated vertebral body bone fracture by the conventional method.

    Improved survival following organ transplantation has brought to the forefront some long-term complications, among which osteoporosis and associated fractures are the major ones that adversely affect the quality of life in recipients. The pathogenesis of osteoporosis in transplant recipients is complex and multifactorial which may be related to increased bone resorption, decreased bone formation, or both. Studies have shown that the preexisting underlying metabolic bone disorders and the use of immunosuppressive agents are the major risk factors for osteoporosis and fractures after organ transplantation. And rapid bone loss usually occurs in the first 6–12 months with a significant increase in fracture risk. This paper will provide an updated review on the possible pathogenesis of posttransplant osteoporosis and fractures, the natural history, and the current prevention and treatment strategies concerning different types of organ transplantation.

    Environmental risk factors for osteoporosis were reviewed at a conference held at the National Institute for Environmental Health Sciences 8-9 November 1993. The conference was co-sponsored by the National Institute of Arthritis and Musculoskeletal and Skin Disease and the NIH Office of Research in Women's Health. The objective of the conference was to review what is known about risk factors for osteoporosis and to identify gaps in the present state of knowledge that might be addressed by future research. The conference was divided into two broad themes. The first session focused on current knowledge regarding etiology, risk factors, and approaches to clinical and laboratory diagnosis. This was followed by three sessions in which various environmental pollutants were discussed. Topics selected for review included environmental agents that interfere with bone and calcium metabolism, such as the toxic metals lead, cadmium, aluminum, and fluoride, natural and antiestrogens, calcium, and vitamin D.

    Estimated number of those with osteoporosis was about 12,800,000, and about 23%, 3,000,000 were male osteoporosis in Japan. Incidence of hip, vertebral, distal radius, and proximal humeral fracture in men was half of that in women. Lifetime risk of hip fracture was 5.6% in men. Risk factors for osteoporotic fracture in men were low bone mineral density(BMD), previous fracture, low body mass index, smoking, family history of fracture, glucocorticoid use and others. For osteoporotic fractures, the fracture risk in smokers was significantly higher in men than in women. There was no differences in fracture risks by BMD, previous fracture, glucocorticoid use, and family fracture history between men and women. PMID:27346311

    Osteoporosis is a polygenetic, environmentally modifiable disease, which precipitates into fragility fractures of vertebrae, hip and radius and also confers a high risk of fractures in accidents and trauma. Aging and the genetic molecular background of osteoporosis cause delayed healing and impair regeneration. The worldwide burden of disease is huge and steadily increasing while the average life expectancy is also on the rise. The clinical need for bone regeneration applications, systemic or in situ guided bone regeneration and bone tissue engineering, will increase and become a challenge for health care systems. Apart from in situ guided tissue regeneration classical ex vivo tissue engineering of bone has not yet reached the level of routine clinical application although a wealth of scaffolds and growth factors has been developed. Engineering of complex bone constructs in vitro requires scaffolds, growth and differentiation factors, precursor cells for angiogenesis and osteogenesis and suitable bioreactors in various combinations. The development of applications for ex vivo tissue engineering of bone faces technical challenges concerning rapid vascularization for the survival of constructs in vivo. Recent new ideas and developments in the fields of bone biology, materials science and bioreactor technology will enable us to develop standard operating procedures for ex vivo tissue engineering of bone in the near future. Once prototyped such applications will rapidly be tailored for compromised conditions like vitamin D and sex hormone deficiencies, cellular deficits and high production of regeneration inhibitors, as they are prevalent in osteoporosis and in higher age.

    The present paper provides an overview of the costs of preventive activities, currently undertaken in Denmark, related to foot and mouth disease (FMD) and classical and African swine fever (SF). Only costs held between outbreaks were included. Costs were divided into public costs and costs paid by the pig and cattle industries, respectively. Data were retrieved from multiple sources such as databases, legal documents, official statistics, yearly reports and expert opinions. As no previous studies have assessed such costs, data collection and estimation procedures were discussed and decided upon in a group of experts from universities, industry, and public authorities. The costs of each preventive activity were related to the type of activity, the number of times the activity was carried out and the share of costs that could be associated with FMD or SF. Uncertainty about parameters was incorporated in the analysis by assuming that the FMD/SF shares of costs as well as total costs for each activity could take on a most likely as well as a minimum and maximum value. A high degree of transparency was prioritized in the cost analysis, which enables reproducibility and easy access to conducting sensitivity analyses. A total of 27 FMD/SF preventive activities were identified. The estimated median (minimum-maximum) of total costs amounted to €32 (18-50) million in 2013. The single most costly FMD/SF related activity, amounting to €8 (5-13) million or 26% of total costs, was a national legal requirement to clean lorries immediately after transportation of live animals. The distribution of costs between stakeholders was estimated to be as follows: pig industry 63%, cattle industry 27%, and the public authorities 10%. Most of the activities focused on reducing the probability of spreading FMD/SF, while only a few activities were directed mainly towards reducing the probability of introduction. Legally required FMD/SF activities (mainly based on EU legislation) accounted

    For the prevention of fractures, antiresorptive drugs (bisphosphonates and denosumab) that decrease high bone resorption and, secondarily, also bone formation, are the mainstream of therapy. Osteoanabolic drugs, such as teriparatide, increase bone formation more than bone resorption, and are used in severe osteoporosis, including patients treated with antiresorptive drugs who still lose bone and have recurrent fractures. New potential drugs for fracture prevention that uncouple bone resorption from bone formation include odanacatib, a specific inhibitor of cathepsin-K, the enzyme that degrades bone collagen type I, that inhibits bone resorption and only temporarily bone formation, and monoclonal antibodies against sclerostin (romosozumab, blosozumab), that stimulate bone formation and decrease bone resorption.

    Osteoporosis has been classified into primary and secondary forms. All patients with osteoporosis should have measurements of 25-hydroxyvitamin D, serum and urine calcium, and some estimation of renal function. There are a wide variety of disorders that lead to secondary osteoporosis, and the tests that confirm these diagnoses are described herein. Making the specific diagnosis is important because treatment of the underlying condition may be sufficient to lessen fracture risk, although some patients may also need usual treatment for osteoporosis. Laboratory testing in addition to a careful history and physical examination will often lead to diagnoses of treatable conditions. PMID:22333732

    Glucocorticoid-induced osteoporosis is the most common cause of secondary osteoporosis. Moreover, it is the most common reason for an osteoporosis among young adults. The clinical use of oral glucocorticoids increases the fracture incidence already within three months after starting the therapy. There does not seem to be a lower threshold: even doses as low as 2,5 mg of prednisone equivalent increase the risk of fractures. Adequate diagnostic and therapy are able to significantly reduce the resulting fracture risk. This article will discuss the pathophysiology of glucocorticoid-induced osteoporosis and give a summary of the current recommendations including the recently updated German guidelines. PMID:26939107

    Over recent decades, the perception of osteoporosis has changed from that of an inevitable consequence of ageing, to that of a well characterised and treatable chronic non-communicable disease, with major impacts on individuals, healthcare systems and societies. Characterisation of its pathophysiology from the hierarchical structure of bone and the role of its cell population, development of effective strategies for the identification of those most appropriate for treatment, and an increasing armamentarium of efficacious pharmacological therapies, have underpinned this evolution. Despite this marked progress, individuals who experience a fragility fracture remain under-treated in many areas of the world, and there is substantial need for investment both in secondary and primary prevention globally. In this brief article, we give an overview of the pathogenesis of osteoporosis, and summarise current and future approaches to its assessment and -treatment. PMID:27481382

    In Singapore, male osteoporosis is gaining greater importance due to our ageing population. Family physicians should screen for osteoporosis in elderly men and men with risk factors or secondary causes for the condition. A bone mineral density (BMD) test is used for diagnosis. FRAX® can be used to predict the absolute ten-year fracture risk. Management includes reduction of risk factors or secondary causes, fall prevention, appropriate physical activity and a diet adequate in calcium and vitamin D. Referrals to specialists for evaluation and therapy can be considered, particularly for younger men with more severe disease. Current first-line drug treatment includes bisphosphonates and teriparatide. Testosterone increases BMD of the spine, but data on fracture risk reduction is unavailable. Public and physician education with the involvement of health authorities can create greater awareness of this silent condition, which can lead to complications, morbidity and death, if left untreated.

    Among the chronic kidney disease-mineral bone disease (CKD-MBD) disorders, osteoporosis and adynamic bone are highly prevalent, and they have been consistently associated with low bone mass, bone fractures, vascular calcifications and greater mortality in general and CKD populations. Despite the fact that osteoporosis and adynamic bone have similar clinical outcomes, they have different pathogeneses and clinical management. In osteoporosis, there is a lack of balance between bone formation and bone resorption, and less new bone is formed to replace bone losses. Osteoporosis is defined by the World Health Organization as "a disease characterized by low bone mineral density and micro architectural deterioration leading to low bone strength and increased risk of fractures." In the general population, there is a good correlation between dual-energy X-ray absorptiometry measurements and bone fractures, but this is not the case with CKD patients. Despite the fact that we have a great number of active antiosteoporotic drugs, the experience in CKD patients is limited. Adynamic bone is suspected based on biochemical parameters, mainly parathyroid hormone (PTH) and bone alkaline phosphatase, but it needs to be proven using a bone biopsy, where a low or zero bone formation rate and a reduction or absence of osteoblasts and osteoclasts should be found. The clinical management of adynamic bone has important limitations and currently does not allow taking many active measures. Treatment is mainly based on the prevention of risk factors known to induce PTH oversuppression, such as aluminium and calcium load and very high doses of vitamin D receptor activators. Due to the limitations in the treatment of both conditions, prevention plays a key role in the management of these disorders. PMID:23023723

    OBJECTIVE: To recommend clinical practice guidelines for the assessment of people at risk for osteoporosis, and for effective diagnosis and management of the condition. OPTIONS: Screening and diagnostic methods: risk-factor assessment, clinical evaluation, measurement of bone mineral density, laboratory investigations. Prophylactic and corrective therapies: calcium and vitamin D nutritional supplementation, physical activity and fall-avoidance techniques, ovarian hormone therapy, bisphosphonate drugs, other drug therapies. Pain-management medications and techniques. OUTCOMES: Prevention of loss of bone mineral density and fracture; increased bone mass; and improved quality of life. EVIDENCE: Epidemiologic and clinical studies and reports were examined, with emphasis on recent randomized controlled trials. Clinical practice in Canada and elsewhere was surveyed. Availability of treatment products and diagnostic equipment in Canada was considered. VALUES: Cost-effective methods and products that can be adopted across Canada were considered. A high value was given to accurate assessment of fracture risk and osteoporosis, and to increasing bone mineral density, reducing fractures and fracture risk and minimizing side effects of diagnosis and treatment. BENEFITS, HARMS AND COSTS: Proper diagnosis and management of osteoporosis minimize injury and disability, improve quality of life for patients and reduce costs to society. Rationally targeted methods of screening and diagnosis are safe and cost effective. Harmful side effects and costs of recommended therapies are minimal compared with the harms and costs of untreated osteoporosis. Alternative therapies provide a range of choices for physicians and patients. RECOMMENDATIONS: Population sets at high risk should be identified and then the diagnosis confirmed through bone densitometry. Dual-energy x-ray absorptiometry is the preferred measurement technique. Radiography can be adjunct when indicated. Calcium and vitamin D

    Osteoporosis, a disorder related to locomotive syndrome, has been nicknamed "the silent disease" since it has no symptoms until fragility fracture occurs. However, a new fragility fracture cannot only reduce daily activity but can also increase fracture risk resulting in possible repetition of the fracture or other new fractures. As a result, daily living activities requiring mobility are often rapidly reduced and the quality of life can be considerably impaired. There are three strategies for preventing fragility fractures : prevention of falls, anti-osteoporosis treatment and hip protectors. A multidisciplinary approach including these strategies should be emphasized to impede the damaging process involved in fragility fracture. PMID:22460510

    Summary Osteoporosis is normally the result of a wrong life-style (diet, physical inactivity, smoke, dental hygiene, intestinal dysbiosis,…) and environmental toxicity which stimulate the chronic expression of inflammatory genes and alter the immuno-endocrine balance. A natural approch should face all the factors involved, leading the patients to become aware of their own responsability, and helping them with natural therapies, healthy food and life-style which support their body in the process of self-healing.

    Objective Although osteoporosis is common following spinal cord injury (SCI), no guidelines exist for its treatment, diagnosis, or prevention. The authors hypothesized that wide variations in diagnosis and treatment practices result from the absence of guidelines. This study sought to characterize the diagnosis and management practices within the VA health care system for osteoporosis following SCI. Design Online survey regarding osteoporosis management in SCI composed of 27 questions designed to gather information on responder demographics, osteoporosis diagnostics, and treatment options. Setting VA health care system. Participants VHA National SCI Staff Physicians and VHA National SCI Nurses (total n = 450) were sent an email with an invitation to participate. Intervention Not applicable. Main Outcome Measures Practice patterns were assessed, including factors associated with ordering a clinical workup and prescribing osteoporosis treatment. Results The response rate was 28%. Ninety-two prescribing practitioners (physicians, nurse practitioners, and physician assistants) were included in the analysis. Of these respondents, 50 (54%) prescribe medications for SCI-induced bone loss; 39 (42%) prescribe bisphosphonates and 46 (50%) prescribe vitamin D. There were 54 (59%) respondents who routinely order diagnostic tests, including dual energy x-ray absorptiometry scans in 50 (54%). Variations in practice were not explained by age, gender, or years practicing SCI medicine. Many respondents (23%) reported barriers to osteoporosis testing including lack of scanning protocols, cost, wheelchair inaccessibility of scanning facilities, and lack of effective treatment guidelines once osteoporosis is diagnosed. Conclusions Despite an absence of screening and treatment guidelines, more than half of all respondents are actively diagnosing and treating osteoporosis with bisphosphonates within the VA health care setting. These data suggest that evidence-based practice guidelines

    Osteoporosis is a major public health problem that affects the entire aging population. This report provides an update on the epidemiology of osteoporosis and its associated fractures. Published studies from 1997 to the present are highlighted. The current US prevalence estimates for osteoporosis, trends in fracture incidence rates, and latest reports on the morbidity, mortality, and costs attributable to osteoporotic fractures are discussed. Recent advances in our understanding of risk factors associated with osteoporosis and related fractures are reviewed. Special attention is paid to the rapid progress being made in the field of genetics, the growing importance of nutrition, and the new questions being raised as to the influence of hormonal factors on bone mineral density and fracture risk. New studies linking osteoporosis to several other important diseases in women including breast cancer, osteoarthritis, and stroke are also reviewed. PMID:11123043

    It is now 75 years since Fuller Albright published his observations on the causal relationship between menopausal estrogen deficiency and osteoporosis. He introduced the concept of menopausal hormone therapy (MHT) for the prevention of osteoporosis. Most of his remarkable observations have stood the test of time and scientific scrutiny. Unfortunately, the uptake of MHT for the prevention of osteoporosis and related fractures remains very low. This can be ascribed to several factors. The availability of new drugs, supported by randomized clinical trials, has increased therapeutic options and created the impression that all new drugs are better compared to MHT. Confusion exists as to the benefit/risk profile of menopausal hormone therapy, limitations on the age of initiation of treatment, limitations on the length of treatment, and the need for treatment in the young menopausal woman with low bone density.

    Abstract Objective To outline the efficacy and risks of bisphosphonate therapy for the management of osteoporosis and describe which patients might be eligible for bisphosphonate “drug holiday.” Quality of evidence MEDLINE (PubMed, through December 31, 2012) was used to identify relevant publications for inclusion. Most of the evidence cited is level II evidence (non-randomized, cohort, and other comparisons trials). Main message The antifracture efficacy of approved first-line bisphosphonates has been proven in randomized controlled clinical trials. However, with more extensive and prolonged clinical use of bisphosphonates, associations have been reported between their administration and the occurrence of rare, but serious, adverse events. Osteonecrosis of the jaw and atypical subtrochanteric and diaphyseal femur fractures might be related to the use of bisphosphonates in osteoporosis, but they are exceedingly rare and they often occur with other comorbidities or concomitant medication use. Drug holidays should only be considered in low-risk patients and in select patients at moderate risk of fracture after 3 to 5 years of therapy. Conclusion When bisphosphonates are prescribed to patients at high risk of fracture, their antifracture benefits considerably outweigh their potential for harm. For patients taking bisphosphonates for 3 to 5 years, reassess the need for ongoing therapy. PMID:24733321

  18. Nanohydroxyapatite Application to Osteoporosis Management

    PubMed Central

    Noor, Zairin

    2013-01-01

    Hydroxyapatite is chemically related to the inorganic component of bone matrix as a complex structure with the formula of Ca10(OH)2(PO4)6. Previous studies have reported the application of microsized hydroxyapatite to bone regeneration, but the result is not satisfied. The limitation comes from the size of hydroxyapatite. In addition, the duration of treatment is very long. The advantages of hydroxyapatite nanocrystal are the osteoconduction, bioresorption, and contact in close distance. Crystal in osteoporotic bone is calcium phosphate hydroxide with the chemical formula of Ca10(OH)2(PO4)6. Crystal of normal bone is sodium calcium hydrogen carbonate phosphate hydrate with the chemical formula of Ca8H2(PO4)6·H2O–NaHCO3–H2O. The recent development is applying nanobiology approach to hydroxyapatite. This is based on the concept that the mineral atoms arranged in a crystal structure of hydroxyapatite can be substituted or incorporated by the other mineral atoms. In conclusion, the basic elements of hydroxyapatite crystals, composed of atomic minerals in a certain geometric pattern, and their relationship to the bone cell biological activity have opened opportunities for hydroxyapatite crystals supplement application on osteoporosis. Understanding of the characteristics of bone hydroxyapatite crystals as well as the behavior of mineral atom in the substitution will have a better impact on the management of osteoporosis.

    Osteoporosis represents the major public health concern worldwide. The purpose of this study was to assess osteoporosis beliefs and actual performance of osteoporosis preventive behaviors in non-academic community Chinese population and to explore whether the differences exist in community females and males. A cross sectional study including 137 females and 122 males was conducted in four non-academic communities of Xi'an city during November 2012, selected by multi-stage sampling method. Self-administered questionnaire was used for data collection. The respondents' mean age was 56.06 ± 5.81 years. 35.5% of the participants had a bone mineral density test. The participants exhibit relatively low osteoporosis health beliefs. The total health belief score was 63.30 ± 8.55 and 64.13 ± 6.47 in females and males respectively. There was significant gender differences in the subscales of Perceived seriousness (p = 0.03), Perceived barriers to exercise (p = 0.004) and Perceived motivation (p = 0.01). Participants had low frequencies of preventive practices. Gender differences were revealed in current smoking and alcohol intake, soybean food intake, smoking history (p < 0.001), alcohol intake history (p = 0.001), meat or egg intake (p = 0.019). The findings from the study suggest an increased awareness of this major public health problem in non-academic Chinese and the scope for enhancing osteoporosis intervention considering the gender difference.

    Osteoporosis is very common, particularly in post-menopausal women and is characterized by a decrease in bone mass and strength. Osteoporosis also affects the jawbone and it is considered a potential contraindication to placement of dental implants. The present paper reviews the literature regarding the effect of osteoporosis on osseointegration of implants. Experimental models have shown that osteoporosis affects the process of osseointegration, which can be reversed by treatment. However, studies in subjects with osteoporosis have shown no differences in survival of the implants compared to healthy individuals. Therefore, osteoporosis cannot be considered a contraindication for implant placement. Oral bisphosphonates are the most commonly used pharmacological agents in the treatment of osteoporosis. Although there have been cases of osteonecrosis of the jaw in patients treated with bisphosphonates, they are very rare and it is more usually associated with intravenous bisphosphonates in patients with neoplasms or other serious diseases. Nevertheless, patients treated with bisphosphonates must be informed in writing about the possibility of this complication and must give informed consent. Ceasing to use bisphosphonates before implant placement does not seem to be necessary. PMID:19767691

    We studied changes in bone mass induced by immobilization and the ability of salmon calcitonin to inhibit immobilization osteoporosis in rat. The bone mass of the immobilized hind leg of rat was compared with the contralateral non-treated leg. Neurectomy and cast immobilization reduced the bone mineral mass to an equal extent. However, the dose-response of calcitonin was different with these immobilization techniques. Calcitonin 15 IU kg-1 administered once daily reduced bone ash weight difference significantly after 2 weeks' neurectomy (P less than 0.001). This had no significant effect on the bone loss induced by cast immobilization, but the dose had to be delivered as two injections given every 12 h. Two weeks' immobilization decreased the incorporation of 45Ca into bones. Calcitonin could not prevent this. However, calcitonin tended to inhibit the overall incorporation of 45Ca into bones in immobilized rats but yet had no effect on 45Ca incorporation in non-immobilized rats. Immobilization decreased serum alkaline phosphatase activity in cast-immobilized animals. Neurectomy did not change serum alkaline phosphatase activity from a sham operation level. The tartrate-resistant acid phosphatase to total acid phosphatase ratio in the serum increased significantly in neurectomized rats and in cast-immobilized calcitonin-treated rats. PMID:2053438

    Osteoporosis has been recognized as a major public health problem for less than two decades. The increasing incidence of fragility fractures, such as vertebral, hip, and wrist fractures, first became apparent from epidemiological studies in the early and mid-1980s, when effective treatment was virtually unavailable. Pharmacological therapies that effectively reduce the number of fractures by improving bone mass are now available widely in countries around the world. Most current agents inhibit bone loss by reducing bone resorption, but emerging therapies may increase bone mass by directly promoting bone formation--as is the case with parathyroid hormone. Current treatment alternatives include bisphosphonates, calcitonin, and selective estrogen receptor modulators, but sufficient calcium and vitamin D are a prerequisite. The availability of evidence-based data that show reductions in the incidence of fractures of 30-50% during treatment has been a major step forward in the pharmacological prevention of fractures. With all agents, fracture reduction is most pronounced for vertebral fracture in high-risk individuals; alendronate and risedronate also may protect against hip fracture in the elderly. New approaches to pharmacological treatment will include further development of existing drugs, especially with regard to tolerance and frequency of dosing. New avenues for targeting the condition will emerge as our knowledge of the regulatory mechanisms of bone remodelling increases, although issues of tissue specificity may be difficult to solve. In the long term, information gained through knowledge of bone genetics may be used to adapt pharmacological treatments more precisely to each individual. PMID:14710507

    Osteoarthritis and osteoporosis are both common conditions in the elderly but their association has long remained obscure. Recently published studies show that patients with osteoarthritis have higher bone mass but no corresponding decrease in fracture risk. This has been proposed to be due to an increased rate of falls in these patients. Multi-disciplinary interventions, vitamin D supplementation and bisphosphonates can play a role on preventing fractures among osteoarthritis patients, but evidence on their efficacy is scarce and of poor quality.

Current approaches to identify individuals at high risk for fracture are based on assessment of bone mineral density and presence of other osteoporosis risk factors. Bone mineral density and susceptibility to osteoporotic fractures are highly heritable, and over 60 loci have been robustly associated with one or both traits through genome-wide association studies carried out over the past 7 years. In this review, we discuss opportunities and challenges for incorporating these genetic discoveries into strategies to prevent osteoporotic fracture and translating new insights obtained from these discoveries into development of new therapeutic targets.

    There are numerous causes of secondary osteoporosis including endocrine disorders, nutritional deficiencies, and other miscellaneous conditions and medications. It is essential to identify and address these factors to appropriately manage patients with osteoporosis. Failure to do so may result in further bone loss despite pharmacologic intervention for osteoporosis. The following diagnostic studies should be considered initially: complete blood count, complete metabolic panel, 25-hydroxyvitamin D level, testosterone level in men, and 24-hour urinary calcium, sodium, and creatinine. Further testing may be performed in selected patients depending on the clinical picture and results of the initial workup. PMID:24100597

    Danish auroral science history begins with the early auroral observations made by the Danish astronomer Tycho Brahe during the years from 1582 to 1601 preceding the Maunder minimum in solar activity. Included are also the brilliant observations made by another astronomer, Ole Rømer, from Copenhagen in 1707, as well as the early auroral observations made from Greenland by missionaries during the 18th and 19th centuries. The relations between auroras and geomagnetic variations were analysed by H. C. Ørsted, who also played a vital role in the development of Danish meteorology that came to include comprehensive auroral observations from Denmark, Iceland and Greenland as well as auroral and geomagnetic research. The very important auroral investigations made by Sophus Tromholt are outlined. His analysis from 1880 of auroral observations from Greenland prepared for the significant contributions from the Danish Meteorological Institute, DMI, (founded in 1872) to the first International Polar Year 1882/83, where an expedition headed by Adam Paulsen was sent to Greenland to conduct auroral and geomagnetic observations. Paulsen's analyses of the collected data gave many important results but also raised many new questions that gave rise to auroral expeditions to Iceland in 1899 to 1900 and to Finland in 1900 to 1901. Among the results from these expeditions were 26 unique paintings of the auroras made by the artist painter, Harald Moltke. The expedition to Finland was headed by Dan la Cour, who later as director of the DMI came to be in charge of the comprehensive international geomagnetic and auroral observations made during the Second International Polar Year in 1932/33. Finally, the article describes the important investigations made by Knud Lassen during, among others, the International Geophysical Year 1957/58 and during the International Quiet Sun Year (IQSY) in 1964/65. With his leadership the auroral and geomagnetic research at DMI reached a high international

    2007-11-01

    The purpose of this paper is to discuss the effects of antifracture drugs on postmenopausal, male and glucocorticoid-induced osteoporosis, focussing on the efficacy and safety of alendronate and risedronate. A search of the literature was conducted using PubMed for strictly conducted systematic reviews published from 1995 to present with homogeneity, meta-analyses with homogeneity, and randomized controlled trials (RCTs) with a narrow confidence interval. According to the results of the systematic reviews and meta-analyses, alendronate and risedronate are useful for the prevention of vertebral and non-vertebral fractures in postmenopausal women with osteoporosis. The results of RCTs have shown the antifracture efficacy of raloxifene and ibandronate against vertebral fractures and that of strontium and parathyroid hormone against vertebral and non-vertebral fractures in postmenopausal women with osteoporosis. In addition, the long-term safety of alendronate, risedronate and raloxifene has been established. On the other hand, RCTs have shown that, only alendronate prevents vertebral fractures in men with osteoporosis, and that alendronate and risedronate can prevent vertebral fractures in patients receiving glucocorticoid treatment. There seems to be less evidence of the antifracture efficacy of the drugs in male and glucocorticoid-induced osteoporosis. They have limitations related to long-term compliance, gastrointestinal intolerance and poor and variable absorption form gastrointestinal tract. Thus, intermittent intravenous administration of bisphosphonates such as ibandronate and zoledronate or subcutaneous administration of denosumab might address some of these problems, although the antifracture efficacy of these drugs needs be established. However, antifracture efficacy and long-term safety are important points in the choice of drugs for the treatment of osteoporosis. Thus, the evidence derived from the literature, based on strict evidence-based medicine

    Hejazi, Zahra Alsadat; Namjooyan, Forough; Khanifar, Marjan

    2016-01-01

    Background: A systemic skeletal disease is characterized by low bone mass and micro-architectural deterioration with a consequent increase in bone fragility and susceptibility to fracture. Asia has the highest increment in the elderly population; therefore, osteoporotic fracture should be a noticeable health issue. The incidence rate of hip fractures in Asia could rise to 45% by the year 2050. Complementary and alternative medicine (CAM) is a group of various medical and health care systems, practices, and products that are not presently considered as part of formal medicine. CAMs have been described as “diagnosis, treatment, and/or prevention which complements mainstream medicine as a holistic, subjective and various natural approaches to medical problems by contributing to a common whole, satisfying claims not met by orthodoxy, or diversifying the conceptual frameworks of medicine”. Methods: Peer-reviewed publications were identified through a search in Scopus, Science Direct, Cochrane, PubMed, and Google scholar using keywords “osteopenia”, “osteoporosis”, “menopause”, “CAM”, “phytoestrogens”, “phytotherapy” and “herbal medicine”. The search was completed in July 2015 and was limited to articles published in English. Relevant articles were identified based on the expertise and clinical experience of the authors. Results: We categorized our results in different classifications including: lifestyle modifications (cigarette, alcohol, exercise and food regimen), supportive cares (intake supplements including vitamin D, C and K), treatments synthetic (routine and newer options for hormone replacement and none hormonal therapies) and natural options (different types of CAM including herbal medicines, yoga and chiropractic). Conclusion: Established osteoporosis is difficult to treat because bone density has fallen below the fracture threshold and trabecular elements may have been lost. Antiresorptive agents can be used to prevent further

    The current study is based on our earlier investigation carried out in 1999, where bone mineral density (BMD) of 35 neurofibromatosis type 1 (NF1) patients was measured and osteoporosis was shown to be common in NF1. The findings have been confirmed by a number of later publications. The purpose of the current longitudinal study was to assess the bone health of these 35 NF1 patients 12 years after the initial study. A total of 28 patients were reached, and BMD of 19 patients was subsequently remeasured. Fracture history of 28/35 NF1 patients who were reached was verified from the medical records. Six NF1 patients had osteoporosis in 1999, and three of them had an osteoporotic fracture between 1999 and 2011, showing an increased fracture risk compared to NF1 patients without osteoporosis. BMD of 19 patients was remeasured in 2011, and four patients who had osteopenia in 1999 had osteoporosis in 2011. The decrease in BMD was not explained by changes in smoking habits, physical activity, sunlight exposure, body mass index, or laboratory parameters, even though secondary hyperparathyroidism was common. Osteoporosis was found in 2011 in patients aged 37 years or older, both men and women. The results showed that NF1-related osteopenia often progresses to osteoporosis since BMD decreases with aging even in young patients. Even though our sample size was 19 patients, we recommend follow-up of NF1 patients with osteopenia and consideration of prophylactic measures to prevent osteoporosis and associated fracture risk.

    Introduction: A great number of clinical studies has indicated that the patients with calcium urolithiasis have a reduced mineral bone density. Aim: The aim of our research was to establish representation of osteoporosis, by measuring mineral bone density using the DEXA method, in patients with calcium urolithiasis, by gender. Material and methods: The research was a prospective one, performed at the University Hospital of the Clinical Center of Banja Luka, at the Urology Clinic and Clinic for Endocrinology, Diabetes and Metabolic Diseases. The material in this research were the patients divided into two groups: a working group (the patients suffering from calcium urolithiasis) and a control group (the patients without calcium urolithiasis). One hundred and twenty (120) patients were included in both these groups, divided in three age subgroups: 20-40, 40-60 and over 60. The total working group consisted of 63 men (52.2%) and 57 (47.5%) women. In the control group, the number of women was 72 (60%) and 48 (40%) of men. Establishing of mineral bone density at L2-L4 of lumbal spine vertebrae and hip was done for the patients in both these groups, using DEXA method. Results: Analysis of mineral bone density using DEXA method in patients by gender of working and control groups has shown that osteoporosis and osteopenia in patients of the working group is significantly more present in women (14% and 22.8%) compared to men (1.6% and 17.5%). When compared by gender in the control group, osteoporosis was present a lot more in women (36.1%) compared to men (2.1%). When observed for the total sample of both the working and control group, there was a statistically significant difference (p<0,01) related to gender structure, where the share of women with osteoporosis/osteopenia was significantly higher (36.1%) compared to men (4.2%). Conclusion: Representation of osteoporosis in women with urolithiasis, particularly of older age, is very expressed and this is why prevention

    SYNOPSIS Glucocorticoid administration is the most common cause of secondary osteoporosis and the leading cause of nontraumatic osteonecrosis. In patients receiving long-term therapy, glucocorticoids induce fractures in 30 to 50% and osteonecrosis in 9 to 40%. This article reviews glucocorticoid-induced osteoporosis and osteonecrosis addressing the risk factors, pathogenesis, evaluation, treatment, and uncertainties in the clinical management of these disorders.

    Osteoporosis is the most common clinical disorder of bone metabolism. With regard to the growing spectrum of therapy options, treatment decisions should be made on an individual basis, taking into account the relative benefits and risks in different patient populations. Prioritization of drugs should be based on the form (primary / secondary) and severity of osteoporosis, sex, age, the specific contraindications and precautions of use of the various available medications and in particular, existing comorbidities.

    2015-01-01

    Background: Spinal cord injury (SCI) is associated with a rapid loss of bone mass, resulting in severe osteoporosis and a 5- to 23-fold increase in fracture risk. Despite the seriousness of fractures in SCI, there are multiple barriers to osteoporosis diagnosis and wide variations in treatment practices for SCI-induced osteoporosis. Methods: We review the biological and structural changes that are known to occur in bone after SCI in the context of promoting future research to prevent or reduce risk of fracture in this population. We also review the most commonly used methods for assessing bone after SCI and discuss the strengths, limitations, and clinical applications of each method. Conclusions: Although dual-energy x-ray absorptiometry assessments of bone mineral density may be used clinically to detect changes in bone after SCI, 3-dimensional methods such as quantitative CT analysis are recommended for research applications and are explained in detail.

    Osteoporotic fractures are potentially devastating and associated with high morbidity and substantial economic burden. Residents of long-term care facilities are at greater risk of osteoporosis and its related fractures than those living in the community, yet osteoporosis is underdiagnosed and undertreated in these settings. Bisphosphonates are approved by the Food and Drug Administration for the treatment and prevention of osteoporosis in postmenopausal women. As a class, bisphosphonates have been shown to increase bone mineral density, decrease the markers of bone resorption, and reduce the risk of osteoporotic fractures. The 3 approved bisphosphonates are alendronate, risedronate, and ibandronate. Alendronate and risedronate are dosed daily or weekly and ibandronate, the most recently approved bisphosphonate, has been approved for monthly oral dosing or as an intravenous formulation to be given intermittently (every 3 months). In addition, other products with different mechanisms of action are in the pharmaceutical pipeline and may offer additional management options. PMID:17845945

    Osteoporosis affects all bones, including those of the facial skeleton. To date the facial bones have not drawn much attention due to the minimal probability of morbid fractures. Hearing and dentition loss due to osteoporosis has been reported. New research findings suggest that radiologic examination of the facial skeleton can be a cost-effective adjunct to complement the early diagnosis and the follow up of osteoporosis patients. Bone-mass preservation treatments have been associated with osteomyelitis of the jawbones, a condition commonly described as osteonecrosis of the jaws (ONJ). The facial skeleton, where alimentary tract mucosa attaches directly to periosteum and teeth which lie in their sockets of alveolar bone, is an area unique for the early detection of osteoporosis but also for the prevention of treatment-associated complications. We review facial bone involvement in patients with osteoporosis and we present data that make the multidisciplinary approach of these patients more appealing for both practitioners and dentists. With regard to ONJ, a tabular summary with currently available evidence is provided to facilitate multidisciplinary practice coordination for the treatment of patients receiving bisphosphonates.

    With the progressive aging of the population, osteoporosis has gradually grown into a global health problem for men and women aged 50 years and older because of its consequences in terms of disabilities and fragility fractures. This is especially true in the People’s Republic of China, which has the largest population and an increasing proportion of elderly people, as osteoporosis has become a serious challenge to the Chinese government, society, and family. Apart from the fact that all osteoporotic fractures can increase the patient’s morbidity, they can also result in fractures of the hip and vertebrae, which are associated with a significantly higher mortality. The cost of osteoporotic fractures, moreover, is a heavy burden on families, society, and even the country, which is likely to increase in the future due, in part, to the improvement in average life expectancy. Therefore, understanding the epidemiology of osteoporosis is essential and is significant for developing strategies to help reduce this problem. In this review, we will summarize the epidemiology of osteoporosis in the People’s Republic of China, including the epidemiology of osteoporotic fractures, focusing on preventive methods and the management of osteoporosis, which consist of basic measures and pharmacological treatments.

    Background Although bisphosphonate is effective for the prevention and treatment of osteoporosis, poor medication compliance is a key-limiting factor. We determined whether alarm clock could improve compliance with weekly bisphosphonate in patients with osteoporosis, by comparing with age- and gender-matched control group. Methods Fifty patients with osteoporosis were recruited and participated in alarm clock group. Patients were asked to take orally weekly risedronate for 1 year, and received alarm clock to inform the time of taking oral bisphosphonate weekly. Using the propensity score matching with age and gender, 50 patients were identified from patients with osteoporosis medication. We compared the compliance with bisphosphonate using medication possession ratio (MPR) between two groups. Results Although there was no significant difference of baseline characteristics between both groups, the mean MPR (0.80±0.33) of alarm clock group was higher than that (0.56±0.34) of control group (P<0.001). Conclusions Alarming could improve the compliance with weekly oral bisphosphonate in patients with osteoporosis. PMID:27294076

    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.

    Many older people, especially women, and their doctors still see osteoporosis as part of the natural course of ageing instead of as a preventable or treatable disorder. Height loss, hyperkyphosis, back pain, and fractures are accepted as consequences of ageing. The notion that it is too late to start treatment in a late stage of the disease forms another barrier to treatment. Although most studies of fracture reduction with medical treatment were not designed for the "geriatric" population, the average age of participants in most clinical trials was about 70 years. In all major studies patients also received calcium and vitamin D supplements. Nowadays, clinicians can choose from several effective treatments for the prevention of osteoporotic fractures in high-risk postmenopausal women. Data on the anti-fracture potential of calcium/vitamin D, raloxifene, bisphosphonates, strontium ralenate, and parathyroid hormone are now available. Bisphosphonates and strontium ralenate are good choices for first- or second-line treatment, while for the time being parathyroid hormone should only be used for the second-line treatment of osteoporosis in the elderly.

    Experimental studies have shown that primary osteoporosis caused by oestrogen-deficiency results in localised alterations in bone tissue properties and mineral composition. Additionally, changes to the lacunar-canalicular architecture surrounding the mechanosensitive osteocyte have been observed in animal models of the disease. Recently, it has also been demonstrated that the mechanical stimulation sensed by osteocytes changes significantly during osteoporosis. Specifically, it was shown that osteoporotic bone cells experience higher maximum strains than healthy bone cells after short durations of oestrogen deficiency. However, in long-term oestrogen deficiency there was no significant difference between bone cells in healthy and normal bone. The mechanisms by which these changes arise are unknown. In this study, we test the hypothesis that complex changes in tissue composition and lacunar-canalicular architecture during osteoporosis alter the mechanical stimulation of the osteocyte. The objective of this research is to employ computational methods to investigate the relationship between changes in bone tissue composition and microstructure and the mechanical stimulation of osteocytes during osteoporosis. By simulating physiological loading, it was observed that an initial decrease in tissue stiffness (of 0.425GPa) and mineral content (of 0.66wt% Ca) relative to controls could explain the mechanical stimulation observed at the early stages of oestrogen deficiency (5 weeks post-OVX) during in situ bone cell loading in an oestrogen-deficient rat model of post-menopausal osteoporosis (Verbruggen et al., 2015). Moreover, it was found that a later increase in stiffness (of 1.175GPa) and mineral content (of 1.64wt% Ca) during long-term osteoporosis (34 weeks post-OVX), could explain the mechanical stimuli previously observed at a later time point due to the progression of osteoporosis. Furthermore, changes in canalicular tortuosity arising during osteoporosis were shown

    The National Institute for Health and Clinical Excellence (NICE) in the UK has recently issued health economic appraisals for the primary and secondary prevention of osteoporotic fracture that are more restrictive than previous guidelines for the management of osteoporosis despite a marked reduction of the cost of intervention. The aim of the present study was to examine the cost-effectiveness of the bisphosphonate, alendronate for the prevention and treatment of fractures associated with osteoporosis. A second aim was to investigate reasons for any disparities in cost-effectiveness between our findings and the NICE appraisals. We compared the effects of alendronate 70 mg weekly by mouth for 5 years with no treatment in postmenopausal women with clinical risk factors for fracture and computed the incremental cost-effectiveness ratio (ICER) using a lifetime simulation model based on Markov cohort methodology. A sensitivity analysis examined other common interventions. Using a threshold of pound sterling 30,000 and pound sterling 20,000 per quality of life-year (QALY) gained to determine cost-effectiveness, alendronate was cost-effective for the primary prevention of fracture in women with osteoporosis irrespective of age as was treatment of women with a prior fragility fracture irrespective of BMD. Cost-effective scenarios were also found in women with strong risk factors for fracture with a bone mineral density value above the threshold for osteoporosis. The results were robust over reasonable assumptions in sensitivity analysis. We conclude that alendronate is a cost-effective agent for the prevention and treatment of fractures associated with osteoporosis. These findings, suitable for informing practice guidance, contrast with recent appraisals from NICE. PMID:18156107

    New noninvasive techniques as well as conventional methods were used to evaluate skeletal mass in the following three populations of adult white women as follows: (1) 79 subjects with preexisting idiopathic scoliosis designated as unstable (US) because of the associated presence in the lumbar spine of lateral spondylolisthesis with segmental instability; (2) 67 subjects with preexisting idiopathic scoliosis without lateral spondylolisthesis designated as stable (SS); and (3) 248 age-matched nonscoliotic controls. Ages in all three groups were categorized into premenopausal (25-44 years), perimenopausal (45-54 years), and postmenopausal (55-84 years). The results showed higher scoliosis morbidity in the US compared to the SS populations. The prevalence and severity of osteoporosis were markedly increased in US versus SS populations. Femoral neck density determined by dual-photon absorptiometry techniques averaged 26% to 48% lower in all age categories of US patients compared to controls. These changes were found in the youngest age groups, indicating reductions in bone mineral content earlier in the adult life of white women with a specific type of high-morbidity US characterized by the marker of lateral spondylolisthesis.

    2013-01-01

    The objective of this study was to provide evidence for the association of early life nutritional deprivation and adult osteoporosis, in order to suggest that a history of such deprivation may be an indicator of increased risk of osteoporosis in later life. The 'fetal programming' of a range of metabolic and cardiovascular disorders in adults was first proposed in the 1990s and more recently extended to disorders of bone metabolism. Localised famines during World War II left populations in whom the long-term effects of maternal, fetal and infantile nutritional deprivation were studied. These studies supported the original concept of 'fetal programming' but did not consider bone metabolism. The present paper offers clinical data from another cohort of World War II famine survivors - those from the Holocaust. The data presented here, specifically addressing the issue of osteoporosis, report on 11 Holocaust survivors in Australia (five females, six males) who were exposed to starvation in early life. The cases show, in addition to other metabolic disorders associated with early life starvation, various levels of osteoporosis, often with premature onset. The cohort studied is too small to support firm conclusions, but the evidence suggests that the risk of adult osteoporosis in both males and females is increased by severe starvation early in life - not just in the period from gestation to infancy but also in childhood and young adulthood. It is recommended that epidemiological research on this issue be undertaken, to assist planning for the future health needs of immigrants to Australia coming from famine affected backgrounds. Pending such research, it would be prudent for primary care health workers to be alert to the prima facie association between early life starvation and adult osteoporosis, and to take this factor into account along with other indicators when assessing a patient's risk of osteoporosis in later life.

    PubMed

    Santora, A C

    Both adequate nutrition and exercise are essential for development of peak adult bone mass and maintenance of bone during aging. The optimal dietary level of a nutrient may vary from individual to individual and may change with age, intake of other nutrients, disease, drug therapy, or sex hormone status. Effects on spinal trabecular bone may not parallel effects on axial cortical bone. Calcium nutrition is important in the prevention of osteoporosis, as calcium is a major constituent of bone. The intake of calcium among most American adults is below the levels recommended by public health agencies. There have been no adequate prospective studies to determine the optimal intake of calcium for preservation of bone mass in young or middle-aged adults, although calcium balance studies indicate that premenopausal women require approximately 1,000 mg of calcium per day. The negative calcium balance of early menopause may be ameliorated by 1,000 mg of calcium per day; however, there is no proof that greater intakes fully reverse the effects of estrogen deficiency. Calcium requirements of both elderly men and women are likely to be greater (between 1,000 and 1,500 mg per day) due to an age-related decrease in the efficiency of intestinal calcium absorption. The optimal level of weight-bearing exercise for maintenance of bone mass in old age is probably similar to that of an active young adult. Maintenance of this activity level in middle and old age improves bone mass. An exercise prescription for elderly individuals must include an appraisal of cardiovascular and muscular-skeletal health and be designed to minimize the risk of trauma during exercise. PMID:3544836

It was revealed that in rats after ovariectomy, the endothelial dysfunction of microcirculation vessels of osteal tissue develops, resulting in occurrence of osteoporosis and delay of consolidation of experimental fractures. Enalapril and losartan prevented the reduction of microcirculation in bone, which was reflected in slowing the thinning of bone trabeculae and in preventing the occurrence of these microfractures, as well as increasing quality of experimental fractures healing.

    Osteoporosis is a burgeoning clinical problem that is characterized by decreased bone strength and density. It predisposes patients to fragility fractures and debilitating spine deformities. Several complications are associated with spine surgery in patients with osteoporosis, and there is currently no treatment algorithm to guide the spine surgeon. A multidisciplinary approach to treatment of patients with osteoporosis and spine deformity or fracture is encouraged, and preoperative planning is crucial for successful surgical outcomes. Several surgical techniques have been developed to treat osteoporosis-related deformities, including posterior instrumentation with fusion. However, achieving fixation and fusion in these patients can be difficult secondary to poor bone stock. Augmentation methods to improve pedicle screw fixation have evolved, including instrumentation at multiple levels, bioactive cement augmentation, and fenestrated or expandable pedicle screws, but their impact on clinical outcomes remains unknown. Management of osteoporosis in patients undergoing spine surgery is challenging, but with appropriate patient selection, medical optimization, and surgical techniques, these patients can experience pain relief, deformity correction, and improved function.

    Varenna, M; Gatti, D

    2010-01-01

    Osteoporosis is a skeletal disease affecting millions of people worldwide in which a decreased bone mass and a microarchitectural deterioration compromise bone strength leading to bone fragility and increased susceptibility to fracture. Bone turnover increases at menopause, with osteoclast-mediated bone resorption exceeding bone formation. Recent discoveries in bone biology have demonstrated that RANKL, a cytokine member of the tumor necrosis factor superfamily, is an essential mediator of osteoclast formation, function and survival. Denosumab is a fully human monoclonal antibody with a high affinity and specificity for human RANKL. By binding to its target, denosumab prevents the interaction of RANKL with its receptor RANK on osteoclasts and their precursors and inhibits osteoclast-mediated bone resorption. Administered as a subcutaneous injection every six months, denosumab has been shown to decrease bone turnover and to increase bone mineral density in postmenopausal women with low bone mass and osteoporosis. In these patients denosumab significantly reduced the risk of vertebral fractures, hip fractures and nonvertebral fractures. In all clinical trials published to date, denosumab was well tolerated with an incidence of adverse events, including infections and malignancy, generally similar to subjects receiving placebo or alendronate. The denosumab therapeutic regimen consisting in a subcutaneous injection every 6 months may increase patient compliance and persistence with a further benefit from treatment. By providing a new molecular target for osteoporosis treatment, denosumab is a promising drug for the treatment of postmenopausal osteoporosis and the prevention of fragility fractures.

    2000-01-01

    OBJECTIVE: To survey physicians in Ontario regarding their approach to diagnosis and treatment of osteoporosis among residents of long-term care facilities. DESIGN: Mailed questionnaire covering physician demographics; current clinical practice relating to osteoporosis; and perceived barriers to prevention, diagnosis, and treatment of the disease. SETTING: Long-term care facilities in Ontario. PARTICIPANTS: Medical directors of long-term care facilities. MAIN OUTCOME MEASURES: Demographic variables; physician attitudes; and practices concerning awareness, diagnosis, and treatment of osteoporosis. RESULTS: Respondents returned 275 of 490 questionnaires, for a response rate of 56.1%. Most respondents (92.4%) were family physicians; 28.7% were caring for more than 100 patients in long-term care. Most (85.8%) saw from one to 10 hip fractures yearly in their practices. Although 49.6% of respondents estimated the prevalence of osteoporosis to be 40% to 80% among their long-term care patients, 45.5% said that they did not routinely assess their patients for the disease, and 26.8% do not routinely treat it. Half (50.9%) of physicians would treat patients at high risk based on clinical history; 47.9% if patients had a vertebral compression fracture on plain x-ray examination; 43.8% if patients were highly functional; 42.0% if osteoporosis were confirmed with bone mineral densitometry; and 30.0% if patients had a recent fracture. Perceived barriers to initiating treatment included cost of therapy, patient or family reluctance to accept therapy, and time or cost of diagnosis. CONCLUSION: Although physicians are aware that patients in long-term care facilities are at high risk for osteoporosis and hip fractures, the disease remains underdiagnosed and undertreated.

  4. Managing the Risk for Early Onset Osteoporosis in Long-Duration Astronauts Due to Spaceflight

    NASA Technical Reports Server (NTRS)

    Sibonga, Jean D.

    2010-01-01

    Early Onset Osteoporosis is probably the most recognized but poorly understood long-term health risk due to spaceflight. Osteoporosis management is primarily prophylactic and clinical interventions rely upon the ability to predict fractures which is currently determined by surrogate measures of bone strength. The RMAT for Early Onset Osteoporosis identified some open issues related to the fact that long-duration astronauts compose a unique group of subjects for which clinical approaches for osteoporosis management do not apply. Long-duration astronauts are healthy, young (25 to 55 years of age), predominantly male, and physical fit relative to the typical osteoporosis patient. Moreover, during prolonged space missions (typically 6-month missions) the skeleton not only adapts to weightlessness, but is influenced by numerous risk factors induced by operational constraints, e.g., inability to maintain preflight weight-bearing and aerobic activities, sub-optimal dietary intake (e.g., high sodium content for food stability, lack of fresh fruit and vegetables), suppression of vitamin D metabolism by uv shielding, and remote medicine care. Moreover, adaptation results in novel changes to astronauts bones that cannot be detected by current medically-useful measures. Consequently, a panel of clinicians (recognized leaders and policy-makers in osteoporosis) was convened to review the dataset of bone measures and bone loss risk factors in long-duration astronauts. Driven by the queries in the RMAT, the panel was charged to determine 1) if an intervention is required to prevent this risk, 2) what type and at what time would intervention be optimal, 3) what is the clinical trigger that would require a medical response from flight surgeons and 4) how should research data be used in the clinical care of astronauts. Hence, the RMAT determined that a bone health policy need to be formulated specific for this unique cohort subjected to a novel skeletal condition

    Objective Osteoporosis is a skeletal disorder characterized by low bone mass and increased bone fragility associated with aging, menopause, smoking, obesity, or diabetes. Persistent inflammation has been identified as an instigating factor in progressive bone loss. In addition to the role of fibrin in coagulation, inordinate fibrin deposition within a tissue matrix results in increased local inflammation. Given that fibrin accumulation is a hallmark of osteoporosis-related co-morbidities, we undertook this study to test the hypothesis that persistent fibrin deposition causes inflammatory osteoporosis. Methods Multiple imaging modalities, bone integrity metrics, and histologic analyses were employed to evaluate skeletal derangements in relation to fibrin deposition, circulating fibrinogen levels, and systemic markers of inflammation in mice that were plasminogen deficient and in plasminogen-deficient mice that were concomitantly either fibrinogen deficient or carrying a mutant form of fibrinogen lacking the αMβ2 binding motif. Results Mice generated with a genetic deficit in the key fibrinolytic protease, plasmin, uniformly developed severe osteoporosis. Furthermore, the development of osteoporosis was fibrin(ogen) dependent, and the derangements in the bone remodeling unit were mechanistically tied to fibrin(ogen)-mediated activation of osteoclasts via activation of the leukocyte integrin receptor αMβ2 on monocytes and secondary stimulation of osteoblasts by RANKL. Notably, the genetic elimination of fibrin(ogen) or the expression of a mutant form of fibrinogen retaining clotting function but lacking the αMβ2 binding motif prevented the degenerative skeletal phenotypes, resulting in normal local and systemic cytokine levels. Conclusion Taken together, these data reveal for the first time that fibrin promotes inflammation-driven systemic osteoporosis, which suggests a novel association between hemostasis, inflammation, and bone biology.

    Background Osteoporosis-related fractures are a significant public health concern. Interventions that increase detection and treatment of osteoporosis, as well as prevention of fractures and falls, are substantially underutilized. This paper outlines the protocol for a pragmatic randomised trial of a multifaceted community-based care program aimed at optimizing the evidence-based management of falls and fractures in patients at risk. Design 6-month randomised controlled study. Methods This population-based study was completed in the Algoma District of Ontario, Canada a geographically vast area with Sault Ste Marie (population 78 000) as its main city. Eligible patients were allocated to an immediate intervention protocol (IP) group, or a delayed intervention protocol (DP) group. The DP group received usual care for 6 months and then was crossed over to receive the interventions. Components of the intervention were directed at the physicians and their patients and included patient-specific recommendations for osteoporosis therapy as outlined by the clinical practice guidelines developed by Osteoporosis Canada, and falls risk assessment and treatment. Two primary outcomes were measured including implementation of appropriate osteoporosis and falls risk management. Secondary outcomes included quality of life and the number of falls, fractures, and hospital admissions over a twelve-month period. The patient is the unit of allocation and analysis. Analyses will be performed on an intention to treat basis. Discussion This paper outlines the protocol for a pragmatic randomised trial of a multi-faceted, community-based intervention to optimize the implementation of evidence based management for patients at risk for falls and osteoporosis.

    Chronic obstructive pulmonary disease (COPD) is a lifestyle-related chronic inflammatory pulmonary disease associated with significant morbidity and mortality worldwide. COPD is associated with various comorbidities found in all stages of COPD. The comorbidities have significant impact in terms of morbidity, mortality, and economic burden in COPD. Management of comorbidities should be incorporated into the comprehensive management of COPD as this will also have an effect on the outcome in COPD patients. Various comorbidities reported in COPD include cardiovascular disease, skeletal muscle dysfunction, anemia, metabolic syndrome, and osteoporosis. Osteoporosis is a significant comorbidity in COPD patients. Various risk factors, such as tobacco smoking, systemic inflammation, vitamin D deficiency, and the use of oral or inhaled corticosteroids (ICSs) are responsible for its occurrence in patients with COPD. This review will focus on the prevalence, pathogenesis, risk factors, diagnosis, and treatment of osteoporosis in COPD patients. PMID:25788838

    Osteoporosis is being increasingly recognised in paediatric practice as a consequence of the increasing life expectancy of children who suffer from chronic diseases and other factors. There are many non-pharmacological measures that can improve children' bone health, for example, avoiding inflammatory activity and osteotoxic treatments; increasing sun exposure and weight-bearing exercise, and maintaining an adequate nutritional status. Vitamin D and calcium supplements have been proposed as a measure to increase bone mass, but their effect and therapeutic indications are not completely clear. On the other hand, bisphosphonates are currently the only pharmacological alternative for the patients with infantile secondary osteoporosis. However, more studies are required on the therapeutic indications, posology, and long term secondary effects of biphosphonates. The aim of this article is to analyze the scientific evidence of the effectiveness of the therapeutic alternatives for childhood secondary osteoporosis and their safety in children. PMID:25441207

    Osteoporosis represents a prominent cause of morbidity in patients with thalassemia. The delay in sexual maturation, the presence of diabetes and hypothyroidism, the parathyroid gland dysfunction, the progressive marrow expansion, the iron toxicity on osteoblasts, the iron chelators, and the deficiency of growth hormone or insulin growth factors have been identified as major causes of osteoporosis in thalassemia. Adequate hormonal replacement, effective iron chelation, improvement of hemoglobin levels, calcium and vitamin D administration, physical activity, and smoking cessation are the main to-date measures for the management of the disease. During the last decade, novel pathogenetic data suggest that the reduced osteoblastic activity, which is believed to be the basic mechanism of bone loss in thalassemia, is accompanied by a comparable or even greater increase in bone resorption. Therefore, the role of bisphosphonates, potent inhibitors of osteoclast activation, arises as a major factor in the management of osteoporosis in thalassemia patients. PMID:20712799

    Cardiovascular disease (CVD) and osteoporosis are common age-related conditions associated with significant morbidity, mortality, and disability. Traditionally, these two conditions were considered unrelated and their coexistence was attributed to independent age-related processes. However, an increasing body of biological and epidemiological evidence has provided support for a link between the two conditions that cannot be explained by age alone. Several hypotheses have been proposed to explain the link between osteoporosis and CVD including: 1) shared risk factors, 2) common pathophysiological mechanisms, 3) common genetic factors, or 4) a causal association. This review highlights the epidemiologic literature on the association of bone density with cardiovascular mortality, cardiovascular morbidity, and subclinical measures of atherosclerosis. It also summarizes the different potential mechanisms involved in the link between osteoporosis and CVD. PMID:22460842

    Purpose of review Excessive bone mineral density (BMD) loss has been associated with schizophrenia, but its mechanisms and clinical implications are less clear. The aim of this review was to summarize the risk of osteoporosis and bone fractures in schizophrenia patients. Moreover, we aimed to examine the impact of antipsychotic-induced hyperprolactinemia on bone metabolism. Recent findings Fifteen of 16 studies (93.8%) reported lower BMD or higher prevalence of osteoporosis in at least one region, or in at least one subgroup of schizophrenia patients compared with controls, but results were inconsistent across measured areas. Higher fracture risk was associated with schizophrenia in 2/2 studies (independently: n = 1), and 3/4 studies with antipsychotics. Reasons for this difference include insufficient exercise, poor nutrition, smoking, alcohol use, and low vitamin D levels. Altogether, 9/15 (60.0%) studies examining the relationship between antipsychotic-induced hyperprolactinemia and BMD loss found some effects of hyperprolactinemia. However, results were mixed, samples and effects were small, and only two studies were prospective. Summary Schizophrenia is associated with reduced BMD and fracture risk. Prevention, early detection, and intervention are required. The relative contributions of antipsychotic-related hyperprolactinemia and unhealthy lifestyle behaviors remain unclear, needing to be assessed in well designed, prospective studies, including bone turnover markers as intermediary endpoints.

    Single- and dual-photon absorptiometric methods have been used in the past to identify populations at risk for bone loss, to define the osteoporotic syndrome in terms of bone mass, and to evaluate treatment regimens to prevent bone loss. Technical improvements have made these procedures available for the nontraumatic measurement of bone mineral in the management of the individual patient suspected of having osteoporosis or other bone loss. This requires a different approach to data interpretation because decisions have to be made on the basis of a single measurement. Osteoporosis and osteomalacia cannot be distinguished by bone mineral measurements because both are characterized by a decrease in content of bone mineral. Bone mineral measurements can be used to assess the risk of fracture and, with it, the severity of bone loss. This allows treatment decisions to be made. Repeated measurements made under well-defined conditions allow estimation of long-term rate of bone loss and monitoring of treatment effect. 38 references.

    Suitable diagnostic strategies beyond general measures of fracture prevention which allow the identification of those individuals who are likely to benefit most from medical treatment are of utmost importance for an efficient treatment of osteoporosis. Since 2003 the "Dachverband Osteologie" (DVO) provides recommendations for the diagnostics and treatment of osteoporosis in German speaking regions. The most recent update was in November 2014. The DVO guideline provides detailed recommendations for a diagnostic examination depending on age, gender, and the presence and strength of clinical risk factors. The number of clinical fractures risks on which the diagnostic and therapeutic recommendations of the DVO guideline 2014 are based has increased in comparison to the DVO guideline 2009. In addition to the fracture risks listed in the previous version of the DVO guideline the list now also includes monoclonal gammopathy of unknown significance, ankylosing spondylitis, COPD, heart failure, celiac disease, type 2 diabetes mellitus, long-term treatment with proton pump inhibitors and a treatment with high-dose inhaled glucocorticoids. For all persons with an increased fracture risk the guideline recommends a diagnostic workup, comprising medical history, clinical examination including assessment of fall risk, DXA measurements at the lumbar spine, proximal total femur and femoral neck, blood analysis and, if indicated, appropriate imaging procedures. The trabecular bone score offers a new diagnostic option for fracture prediction. PMID:26536643

    As women age and enter menopause, they are sometimes more susceptible than men to certain physical and mental disorders such as osteoporosis and late-onset schizophrenia. Risedronate (Actonel©) is a bisphosphonate used for the treatment of osteopenia. Early initiation of pharmacotherapy for osteopenia is recommended to prevent greater bone loss. The most common side effects of risedronate include fever and flu-like symptoms, hypocalcemia, bone and joint pain, peripheral edema, fatigue, change in bowel movements, osteonecrosis of the jaw, and atrial fibrillation. Though reports in the professional literature of psychotic reactions to risedronate are scant, there have been FDA reports as well as patient discussions of psychiatric side effects from this medication on popular websites. We report the case of M, age 59, who was treated with risedronate for osteoporosis, and was subsequently diagnosed with atypical psychosis after other organic causes were excluded. Though it is conceivable that age-related psychosocial and physical factors triggered late-onset schizophrenia, the temporal relationship between the termination of treatment with risedronate and the improvement in her mental state suggests that the risedronate might have triggered a psychotic reaction that resolved following cessation of treatment.

    Transient osteoporosis of the hip (TOH) is an uncommon condition. This painful regional osteoporosis affects previously healthy women in the third trimester of pregnancy. It is characterized by pain in the affected hip and pronounced osteopenia of the femoral head and neck. It has a relatively short clinical course (average 6 months) and a predictably benign prognosis. Complete clinical and radiological recovery is the rule. The diagnosis is one of exclusion. The cause of the osteopenia is not known, although various aetiological factors have been implicated. A case of TOH occurring in the third trimester of pregnancy with complete recovery within 6 months postpartum is presented. PMID:9325501

    The osteoporosis-pseudoglioma syndrome (MIM 259770) is a rare autosomal recessive disorder in which bone fragility and frequent fractures are associated with serious ocular changes. The skeletal manifestations resemble those of osteogenesis imperfecta while hyperplasia of the vitreous, eye and corneal opacities often mimics the appearance of intraocular glioma. This disorder was previously reported in a South African family of Indian stock as 'the ocular form of osteogenesis imperfecta'. Terminological discussion followed and it was suggested that these individuals had osteoporosis-pseudoglioma syndrome. This article describes and depicts the manifestations of the disorder and discusses the nosology. PMID:27245540

    The purpose of this paper was to investigate the preventive effects and long term effects of extremely low frequency pulsed electromagnetic fields (PEMFs), generated by circular coils and pulsed electromagnetic fields stimulators, on osteoporosis in bilaterally ovariectomized rats. In preventive experiment, thirty three-month old female Sprague-Dawley rats were randomly divided into three different groups: sham (SHAM), ovariectomy (OVX), PEMFs stimulation (PEMFs). All rats were subjected to bilaterally ovariectomy except those in SHAM group. The PEMFs group was exposed to pulsed electromagnetic fields with frequency 15 Hz, peak magnetic induction density 2.2mT and exposure time 2 hours per day. The bone mineral density (BMD) of vertebra and left femur were measured by dual energy X-ray absorptiometry at eighth week, twelfth week and sixteenth week after surgery. In long term effects experiment, forty four rats were randomly divided into sham (14 rats, SHAM), ovariectomy group (10 rats, OVX), 15Hz PEMFs group(10 rats, 15Hz) and 30Hz PEMFs group(10 rats, 30Hz) at twenty-sixth week after surgery. Rats in PEMFs groups were stimulated sixteen weeks. In preventive experiment, the Corrected BMD of vertebra and femur was significantly higher than that of OVX group after 16 weeks (P<0.001, P<0.001 respectively). In long term effects experiment, the vertebral BMD of 15Hz PEMFs group and 30Hz PEMFs group was significantly higher than that of OVX groups (P<0.01, P<0.05 respectively). The experimental results demonstrated that extremely low intensity, low frequency, single pulsed electromagnetic fields significantly slowed down the loss of corrected vertebral and femoral BMD in bilaterally ovariectomized rats and suggest that PEMFs may be beneficial in the treatment of osteoporosis.

    PURPOSE We wanted to develop and validate a clinical prediction rule to identify men at risk for osteoporosis and subsequent hip fracture who might benefit from dual-energy x-ray absorptiometry (DXA). METHODS We used risk factor data from the National Health and Nutrition Examination Survey III to develop a best fitting multivariable logistic regression model in men aged 50 years and older randomized to either the development (n = 1,497) or validation (n = 1,498) cohorts. The best fitting model was transformed into a simplified scoring algorithm, the Male Osteoporosis Risk Estimation Score (MORES). We validated the MORES, comparing sensitivity, specificity, and area under the receiver operating characteristics (ROC) curve in the 2 cohorts and assessed clinical utility with an analysis of the number needed-to-screen (NNS) to prevent 1 additional hip fracture. RESULTS The MORES included 3 variables—age, weight, and history of chronic obstructive pulmonary disease—and showed excellent predictive validity in the validation cohort. A score of 6 or greater yielded an overall sensitivity of 0.93 (95% CI, 0.85–0.97), a specificity of 0.59 (95% CI, 0.56–0.62), and an area under the ROC curve of 0.832 (95% CI, 0.807–0.858). The overall NNS to prevent 1 additional hip fracture was 279 in a cohort of men representative of the US population. CONCLUSIONS Osteoporosis is a major predictor of hip fractures. Experts believe bisphosphonate treatment in men should yield results similar to that in women and reduce hip fracture rates associated with osteoporosis. In men aged 60 years and older, the MORES is a simple approach to identify men at risk for osteoporosis and refer them for confirmatory DXA scans. PMID:18025492

    Background Osteoporosis is a debilitating condition characterized by fractures, pain and premature death. Risk factors for osteoporosis predict the risk of fragility fractures. Aim To describe the occurrence of risk factors for osteoporosis among populations in Nuuk, the capital of Greenland. Methods A random sample of women born in 1934–42, 1945–47, 1956, and men born in 1956 were selected from the national civil registry. A questionnaire was sent out in Greenlandic and Danish on risk factors for osteoporosis: family history, smoking habits, alcohol intake, presence of disease, sun exposure, intake of dairy products, age at menopause (women) and number of falls. Additional questions included the frequency of back pain, previous fractures, intake of vitamin D and calcium supplements, use of anti-osteoporotic drugs, steroids and other drugs. Results The questionnaire was sent to 317 subjects confirmed to be living at an address in Nuuk and 181 (57.1%) responded. More young women than older women were smokers (60.6% vs. 35.0%; p=0.022) while limited sun exposure was reported by more of the old women (37.2% vs. 5.6%; p=0.003). Family history of osteoporosis was reported by 15.0%, without difference between groups. Alcohol and milk intake did not differ between groups. Premature menopause was reported by 17.9% of the women. Falls within the last year were reported by 42.4% with fewer falls in the oldest age group (21.9% vs. 50.0%; p=0.005). Frequency of fragility fractures increased with age (5.7% vs. 24.3% vs. 30.4%; p=0.02) and the risk of a fragility fracture increased with age (p=0.004; OR, 95% CI: 4.5, 1.6–12.2, reference: below 70 years), when adjusted for smoking, gender and falls. The use of anti-osteoporotic drugs was low (3.4%) while 28.8% took calcium and vitamin D supplements. Conclusions Age is a dominating risk factor for fragility fractures in Greenland. The use of anti-osteoporotic drugs is low in Greenland, even if osteoporotic fractures are

    Summary Primary osteoporosis is related to bone loss from ageing. Secondary osteoporosis results from specific conditions that may be reversible. A thoracolumbar X-ray is useful in identifying vertebral fractures, and dual energy X-ray absorptiometry is the preferred method of calculating bone mineral density. The density of the total hip is the best predictor for a hip fracture, while the lumbar spine is the best site for monitoring the effect of treatment. The T-score is a comparison of the patient’s bone density with healthy, young individuals of the same sex. A negative T-score of –2.5 or less at the femoral neck defines osteoporosis. The Z-score is a comparison with the bone density of people of the same age and sex as the patient. A negative Z-score of –2.5 or less should raise suspicion of a secondary cause of osteoporosis. Clinical risk calculators can be used to predict the 10-year probability of a hip or major osteoporotic fracture. A probability of more than 5% for the hip or more than 20% for any fracture is abnormal and treatment may be warranted. PMID:27340320

    Overall, drug therapies for osteoporosis in men are less defined than in women, mainly due to the fact that there are fewer RCTs performed in male populations, to the relatively smaller sample sizes, and to the lack of long-term extension studies. In a series of well-designed RCTs, alendronate, risedronate, zoledronic acid, and teriparatide were demonstrated to reduce the risk of new vertebral fractures in men presenting with primary osteoporosis(including osteoporosis associated with low testosterone levels)and to improve the bone mineral density(BMD). In preliminary studies, ibandronate and denosumab also showed their beneficial effects on surrogate outcomes(BMD and markers of bone turnover)in men with osteoporosis. Although direct evidence about their non-vertebral anti-fracture efficacy are lacking, the effects of bisphosphonates, denosumab and teriparatide on surrogate outcomes were similar to those reported in pivotal RCTs undertaken in postmenopausal women, in which vertebral and non-vertebral anti-fracture efficacy have been clearly demonstrated.

    Osteoporosis is a disease of bone which is common in middle aged post-menopausal women. The osteoporotic bones will become weak and are prone to fractures. Osteoporosis means “porous bone” is a “silent disease”. Healthy bone microscopically appears like a honeycomb but, in osteoporotic patients the spaces are much bigger. The osteoporotic bone will have less density or mass and the structure of bone tissue is abnormal. As the bone becomes less dense, they become weaker and more likely to fracture. Women are four times more likely to develop osteoporosis than men. Oral health maintenance for adults with osteoporosis is important. Bone weakness and loss may also affect the ridges that hold dentures resulting in poor fitting dentures. The patients require new dentures more often than those who have strong, healthy bones. Best way to handle problems is avoid delaying or postponing the dental treatment. Regular dental visits and healthy lifestyle is necessary in strengthening and maintenance of good bone health. Well balanced diet with high amounts of vitamin-D & calcium with regular physical activity is recommended. PMID:26816999

    Background Osteoporosis is a disease of bone metabolism in which bisphosphonates (BPS) are the most common medications used in its treatment, whose main objective is to reduce the risk of fractures. The aim of this study was to conduct a systematic review on BPs adherence for treatment of osteoporosis. Methods Systematic review of articles on BPs adherence for treatment of osteoporosis, indexed on MEDLINE (via PubMed) databases, from inception of databases until January 2013. Search terms were “Adherence, Medication” (MeSH term), “Bisphosphonates” (MeSH term), and “Osteoporosis” (MeSH term). Results Of the 78 identified studies, 27 met the eligibility criteria. Identified studies covered a wide range of aspects regarding adherence and associated factors, adherence and fracture, adherence and BPs dosage. The studies are mostly observational, conducted with women over 45 years old, showing low rates of adherence to treatment. Several factors may influence adherence: socio-economic and cultural, participation of physicians when guidance is given to the patient, the use of bone turnover markers, and use of generic drugs. The monthly dosage is associated with greater adherence compared to weekly dosage. Conclusions Considering the methodological differences between the studies, the results converge to show that adherence to treatment of osteoporosis with BPs is still inadequate. Further experimental studies are needed to evaluate the adherence and suggest new treatment options. PMID:23705998

The pathogenesis of osteoporosis is multifactorial; whereas traditional pathophysiological concepts emphasize endocrine mechanisms, it has been recognized that also components of the immune system have a significant impact on bone. Since 2000, when the term 'osteoimmunology' was coined, novel insights into the role of inflammatory cytokines by influencing the fine-tuned balance between bone resorption and bone formation have helped to explain the occurrence of osteoporosis in conjunction with chronic inflammatory reactions. Moreover, the phenomenon of a low-grade, chronic, systemic inflammatory state associated with aging has been defined as 'inflamm-aging' by Claudio Franceschi and has been linked to age-related diseases such as osteoporosis. Given the tight anatomical and physiological coexistence of B cells and the bone-forming units in the bone marrow, a role of B cells in osteoimmunological interactions has long been suspected. Recent findings of B cells as active regulators of the RANK/RANKL/OPG axis, of altered RANKL/OPG production by B cells in HIV-associated bone loss or of a modulated expression of genes linked to B-cell biology in response to estrogen deficiency support this assumption. Furthermore, oxidative stress and the generation of advanced glycation end products have emerged as links between inflammation and bone destruction. PMID:26088283

    Immunisation information systems (IIS) are valuable tools for monitoring vaccination coverage and for estimating vaccine effectiveness and safety. Since 2009, an advanced IIS has been developed in Denmark and will be implemented during 2012–14. This IIS is based on a database existing since 2000. The reporting of all administered vaccinations including vaccinations outside the national programme will become mandatory. Citizens will get access to data about their own vaccinations and healthcare personnel will get access to information on the vaccinations of their patients. A national concept of identification, a national solution combining a personal code and a card with codes, ensures easy and secure access to the register. From the outset, the IIS will include data on childhood vaccinations administered from 1996 and onwards. All Danish citizens have a unique identifier, a so called civil registration number, which allows the linking of information on vaccinations coming from different electronic data sources. The main challenge will be to integrate the IIS with the different electronic patient record systems currently existing at general practitioner, vaccination clinic and hospital level thereby avoiding double-entry. A need has been identified for an updated international classification of vaccine products on the market. Such a classification would also be useful for the future exchange of data on immunisations from IIS between countries. PMID:22551494

    The National Osteoporosis Society (NOS) published its document, Vitamin D and Bone Health: A Practical Clinical Guideline for Patient Management, in 2013 as a practical clinical guideline on the management of vitamin D deficiency in adult patients with, or at risk of developing, bone disease. There has been no clear consensus in the UK on vitamin D deficiency its assessment and treatment, and clinical practice is inconsistent. This guideline is aimed at clinicians, including doctors, nurses and dieticians. It recommends the measurement of serum 25 (OH) vitamin D (25OHD) to estimate vitamin D status in the following clinical scenarios: bone diseases that may be improved with vitamin D treatment; bone diseases, prior to specific treatment where correcting vitamin D deficiency is appropriate; musculoskeletal symptoms that could be attributed to vitamin D deficiency. The guideline also states that routine vitamin D testing is unnecessary where vitamin D supplementation with an oral antiresorptive treatment is already planned and sets the following serum 25OHD thresholds: <30 nmol/l is deficient; 30-50 nmol/l may be inadequate in some people; >50 nmol/l is sufficient for almost the whole population. For treatment, oral vitamin D3 is recommended with fixed loading doses of oral vitamin D3 followed by regular maintenance therapy when rapid correction of vitamin D deficiency is required, although loading doses are not necessary where correction of deficiency is less urgent or when co-prescribing with an oral antiresorptive agent. For monitoring, serum calcium (adjusted for albumin) should be checked 1 month after completing a loading regimen, or after starting vitamin D supplementation, in case primary hyperparathyroidism has been unmasked. However, routine monitoring of serum 25OHD is generally unnecessary but may be appropriate in patients with symptomatic vitamin D deficiency or malabsorption and where poor compliance with medication is suspected.

    Osteoporosis is a complex human disease that results in increased susceptibility to fragility fractures. It can be phenotypically characterized using several traits, including bone mineral density, bone size, bone strength, and bone turnover markers. The identification of gene variants that contribute to osteoporosis phenotypes, or responses to therapy, can eventually help individualize the prognosis, treatment, and prevention of fractures and their adverse outcomes. Our previously published reviews have comprehensively summarized the progress of molecular genetic studies of gene identification for osteoporosis and have covered the data available to the end of September 2007. This review represents our continuing efforts to summarize the important and representative findings published between October 2007 and November 2009. The topics covered include genetic association and linkage studies in humans, transgenic and knockout mouse models, as well as gene-expression microarray and proteomics studies. Major results are tabulated for comparison and ease of reference. Comments are made on the notable findings and representative studies for their potential influence and implications on our present understanding of the genetics of osteoporosis. PMID:20357209

    Bisphosphonates are the most widely prescribed treatment for postmenopausal osteoporosis, secondary osteoporosis, and male osteoporosis. Notwithstanding their high effectiveness and favorable safety profile, the adherence to bisphosphonate treatment remains low. Different treatment strategies aim to improve the clinical effectiveness of bisphosphonate therapy. This review paper assesses the clinical utility of oral intermittent risedronate in the treatment of postmenopausal osteoporosis. The new delayed-release risedronate formulation is a safer and easy to use alternative to other risedronate therapy. Oral risedronate, a potent nitrogen-containing bisphosphonate, has been extensively studied using daily regimens. A new intermittent (weekly) dosing regimen confirmed its clinical effectiveness in relation to vertebral and nonvertebral fracture prevention. The absence of significant differences in the incidence of adverse effects confirmed the favorable tolerability of the weekly dosage. In efforts to improve patient adherence to treatment, an innovative, delayed-release formulation of risedronate, which ensures adequate bioavailability of the active compound when taken with food, was introduced. The once-weekly delayed-release formulation of risedronate proved to be noninferior to the daily dosage of risedronate in terms of bone mineral density and markers of bone turnover. In addition, the incidence of new morphometric vertebral fractures was comparable in both treatment regimens. The new delayed-release formulation of risedronate showed a favorable safety profile. Delayed-release risedronate is a promising, new, effective, and convenient alternative to current bisphosphonate treatments. It appears to allow better patient adherence to antiresorptive treatment.

    2012-01-01

    Denosumab is a breakthrough biological drug approved by the Food and Drug Administration and European Medicines Agency for the treatment of osteoporosis in 2010. It is a fully human monoclonal antireceptor activator of nuclear factor kappa-B ligand antibody, which inhibits the activity of osteoclasts, resulting in an antiresorptive effect with a significant increase in bone mineral density. The FREEDOM (Fracture Reduction Evaluation of Denosumab in Osteoporosis every 6 Months) trial, comparing denosumab with no treatment in 7868 women with postmenopausal osteoporosis, showed an important reduction of fracture risk at hip, vertebral, and nonvertebral sites in the treated group, while no statistically significant difference in the incidence of adverse events was detected between denosumab and placebo groups. The specific action of denosumab directed against a key regulator of osteoclasts makes it a valuable tool in preventing the occurrence of skeletal events caused by bone destruction in patients with advanced malignancies. The drug was approved for postmenopausal osteoporosis in women at increased risk of fracture and for the treatment of bone loss associated with androgen deprivation therapy in men with prostate cancer.

    Objective Low bone density and osteoporosis prevalence, while well-documented in wealthy nations, are poorly studied in rural, non-clinical contexts in economically-developing regions such as Latin America. This study contributes preliminary osteoporosis risk data for a rural Colono (mestizo) population from Amazonian Ecuador. Methods Anthropometrics were collected for 119 adult participants (74 females, 45 males [50–90 years old]). Heel bone density and T-scores were recorded using calcaneal ultrasonometry Results Approximately 33.6% of the participants had low bone density and were at high-risk for osteoporosis. Four times as many females as males were considered high-risk. Consistent with epidemiological literature, advancing age was significantly associated with lower bone density values (p=0.001). Conclusions Low bone density and osteoporosis prevalence are expected to increase in this and other economically-transitioning populations, yet infrastructure to monitor this changing epidemiological landscape is almost non-existent. Human biologists are uniquely positioned to contribute data from remote populations, a critical step towards initiating increased resource allocation for diagnosis and prevention. PMID:25242164

    Osteoporotic fractures are a major cause of morbidity in the elderly population. Since postmenopausal osteoporosis is related to an increase in osteoclastic activity at the time of menopause, inhibitors of bone resorption have genuinely been considered an adequate strategy for prevention and treatment of osteoporosis. Bisphosphonates and selective oestrogen receptor modulators are widely prescribed to treat osteoporosis. However, other antiresorptive drugs have been developed for the management of osteoporosis, with the objective of providing a substantial reduction in osteoporotic fractures at all skeletal sites, combined with an acceptable long-term skeletal and systemic safety profile. Denosumab, a human monoclonal antibody to receptor activator for nuclear factor kappa B ligand, has shown efficacy against vertebral, nonvertebral and hip fractures. Its administration every 6 months as a subcutaneous formulation might significantly influence compliance and persistence to therapy. Additional results regarding long-term skeletal safety (i.e. osteonecrosis of the jaw and atypical diaphyseal femoral fracture) are needed. Odanacatib, a selective cathepsin K inhibitor, is a promising new approach to the inhibition of osteoclastic resorption, with the potential to uncouple bone formation from bone resorption. Results regarding its anti-fracture efficacy are expected in the coming months. PMID:24797286

    Osteoporosis (OP) has emerged as a frequent and devastating complication of organ solid transplantation process. Bone loss after organ transplant is related to adverse effects of immunosuppressants on bone remodeling and bone quality. Many factors contribute to the pathogenesis of OP in transplanted patients. Many mechanisms of OP have been deeply approached. Drugs for OP can be generally divided into "bone resorption inhibitors" and "bone formation accelerators," the former hindering bone resorption by osteoclasts and the latter increasing bone formation by osteoblasts. Currently, bisphosphonates, which are bone resorption inhibitors drugs, are more commonly used clinically than others. Using the signaling pathway or implantation bone marrow stem cell provides a novel direction for the treatment of OP, especially OP after transplantation. This review addresses the mechanism of OP and its correlation with organ transplantation, lists prevention and management of bone loss in the transplant recipient, and discusses the recipients of different age and gender.

    Osteoporosis is a "silent" disease and the patient has usually no clue of it until the occurrence of a fragility fracture. Prevention requires a continuous daily treatment that could be uncomfortable to the patient. Besides the recently introduced weekly oral schedules, injectable bisphosphonates have often been used as an off-label option to ameliorate compliance. In general, although with different efficiency, almost all injectable bisphosphonates can improve bone mineral density and suppress bone resorption markers. The effect of intravenous infusions of bisphosphonates are, to a large extent, similar to equivalent intramuscular administrations, but doses and dosing intervals represent the critical issues. Pain at the injection site and acute phase reactions are relatively common to intramuscular clodronate and intravenous infusions of nitrogen-containing bisphosphonates, respectively. Under certain circumstances, intermittent treatment with injectable bisphosphonates might represent a feasible alternative when compliance is at risk. PMID:14661816

    Odanacatib represents a novel treatment option in the approach of postmenopausal women. Postmenopausal women with osteoporosis experience a disturbance in bone remodeling wherein bone resorption exceeds bone formation. Cathepsin K is a lysosomal cysteine protease found primarily in osteoclasts that plays a major role in the breakdown of bone via its collagenase properties. Targeting a new area of pathophysiology, odanacatib inhibits cathepsin K to reduce bone resorption while preserving bone formation. Phase II and III trials have shown efficacy in increasing bone mineral density in the target treatment group. Overall, safety studies have found odanacatib to be well-tolerated and comparable to placebo; however, some imbalances in adverse events have been observed in the Phase III trials. Current and future studies will analyze the long-term ability of odanacatib in preventing bone fracture. PMID:26344800

    The global burden of osteoporotic fractures is associated with significant morbidity, mortality, and healthcare costs. We examined the ClinicalTrials.gov database to determine whether recently registered clinical trials addressed prevention and treatment in those at high risk for fracture. A dataset of 96,346 trials registered in ClinicalTrials.gov was downloaded on September 27, 2010. At the time of the dataset download, 40,970 interventional trials had been registered since October 1, 2007. The osteoporosis subset comprised 239 interventional trials (0.6%). Those trials evaluating orthopedic procedures were excluded. The primary purpose was treatment in 67.0%, prevention in 20.1%, supportive care in 5.8%, diagnostic in 2.2%, basic science in 3.1%, health services research in 0.9%, and screening in 0.9%. The majority of studies (61.1%) included drug-related interventions. Most trials (56.9%) enrolled only women, 38.9% of trials were open to both men and women, and 4.2% enrolled only men. Roughly one fifth (19.7%) of trials excluded research participants older than 65 years, and 33.5% of trials excluded those older than 75 years. The funding sources were industry in 51.0%, the National Institutes of Health in 6.3%, and other in 42.7%. We found that most osteoporosis-related trials registered from October 2007 through September 2010 examined the efficacy and safety of drug treatment, and fewer trials examined prevention and non-drug interventions. Trials of interventions that are not required to be registered in ClinicalTrials.gov may be underrepresented. Few trials are specifically studying osteoporosis in men and older adults. Recently registered osteoporosis trials may not sufficiently address fracture prevention. PMID:27191848

    Objective: To evaluate the prevalence of osteoporosis in patients awaiting total hip arthroplasty. Method: Twenty-nine patients diagnosed with hip osteoarthritis awaiting primary total arthroplasty of the hip answered WOMAC questionnaire, VAS and questions about habits, osteoporosis and related diseases. Bone mineral densitometry of the lumbar spine and hips and laboratory tests (complete blood count and examination of calcium metabolism) were performed. Weight and height were measured to calculate body mass index (BMI). The evaluated quantitative characteristics were compared between patients with and without osteoporosis using the Mann-Whitney tests. Results: Thirteen men and 16 women with a mean age of 61.5 years old, WOMAC 51.4; EVA 6.4 and BMI 27.6 were evaluated. The prevalence of osteoporosis was 20.7%, and 37.9% had osteopenia. Patients with osteoporosis were older than patients without osteoporosis (p=0.006). The mean bone mineral density of the femoral neck without hip osteoarthritis was lower than the affected side (p=0.007). Thirty-five percent of patients did not know what osteoporosis is. Of these, 30% had osteopenia or osteoporosis. Conclusion: osteoarthritis and osteoporosis may coexist and the population waiting for total hip arthroplasty should be considered at risk for the presence of osteoporosis.

    Bisphosphonates have been widely prescribed to postmenopausal women for treatment and prevention of osteoporosis. Given a background of reports of recent safety problems, questions about optimal duration of use, and the patent expiration of Fosamax in February 2008, we accessed data from pharmaceutical marketing research databases to describe trends in dispensed prescriptions and sales of oral bisphosphonates, characteristics of patients and prescribers, and sales of intravenous bisphosphonates for osteoporosis treatment. An estimated 21.3million prescriptions for oral bisphosphonates were dispensed in U.S. retail pharmacies in 2002 that increased 46% to a peak of 31.0million in 2007 and 2008, and declined by 53% in a four year-period to 14.7million in 2012. Sales data (number of packages sold in all settings of care) showed parallel trends (66% increase from 2002 through 2007 and 51% decrease from 2007 through 2012). Similarly, intravenous bisphosphonate sales for osteoporosis treatment grew 3.8-fold from 149.5 thousand packages in 2007 to 561.6 thousand in 2010, followed by a 22% decrease in 2012. Data from an ongoing monthly office-based survey indicated physicians mentioned oral bisphosphonates primarily in visits of older aged Caucasian women with lower body mass for osteoporosis. Frequencies of oral bisphosphonate mentions increased between 2002 and 2012 in visits of Asians and for osteopenia diagnoses. These data indicate a substantial decline in prescriptions and sales of oral (since 2007-2008) and intravenous (since 2010) bisphosphonates for osteoporosis treatment in the United States. Reasons for, and implications of, the decline should be considered for future research. PMID:24063946

    Utilizing a sciatic neurectomy model of disuse osteoporosis, the effects on rates of bone formation and bone resorption were examined when a capacitively coupled electrical signal was applied to the denervated tibia in the rat. It was found that a low-voltage, symmetrical sine wave, 60-kHz, capacitively coupled signal had no significant effect on the amount of bone resorption occurring in denervated right tibiae in rats previously labeled with [3H]tetracycline. This was true whether the signal was applied while osteoporosis was developing (prevention of osteoporosis) or after it had been established (treatment of osteoporosis). If a similar capacitively coupled signal was applied to rats in which osteoporosis was well established, and the rats were labeled with [3H]tetracycline daily during a 12-day treatment period, it was found that there was statistically significant enhancement of the amount of new bone formation (increased [3H]tetracycline incorporation) in the tibiae that received the signal as compared with that of the controls. These results indicate that prevention or amelioration of disuse osteoporosis that occurs with a capacitively coupled electrical signal is due not to a change in the rate of bone resorption, but to an increase in the rate of bone formation.

    Rheumatoid arthritis (RA) is a chronic systemic connective tissue disease. The development of comorbidities often occurs in the course of RA. One of them is osteoporosis, which has serious social and economic effects and may contribute to the increase in the degree of disability and premature death of the patient. Due to the young age in which RA disease occurs, densitometry (DXA) of the lumbar spine is the basic examination in osteoporosis diagnostics. In the course of RA, much more frequently than in healthy persons of the same age, osteoporotic fractures of vertebral bodies occur, which hinder a correct assessment in the DXA test. Rheumatoid arthritis patients often undergo computed tomography (CT) examination of the abdominal cavity for other medical indications than suspected spinal injury. Then, CT examination may also serve for the assessment of bone density, especially in patients with osteoporotic fractures. PMID:27407274

    2016-01-01

    Osteoporosis is a systemic metabolic bone disorder characterized by a decrease in bone mass and degradation of the bone microstructure, leaving bones that are fragile and prone to fracture. Most osteoporosis treatments improve symptoms, but to date there is no quick and effective therapy. Bone marrow mesenchymal stem cells (BMMSCs) have pluripotent potential. In adults, BMMSCs differentiate mainly into osteoblasts and adipocytes in the skeleton. However, if this differentiation is unbalanced, it may lead to a decrease in bone mass. If the number of adipocyte cells increases and that of osteoblast cells decreases, osteoporosis can result. A variety of hormones and cytokines play an important role in the regulation of BMMSCs bidirectional differentiation. Therefore, a greater understanding of the regulation mechanism of BMMSC differentiation may provide new methods to prevent and treat osteoporosis. In addition, autologous, allogeneic BMMSCs or genetically modified BMMSC transplantation can effectively increase bone mass and density, increase bone mechanical strength, correct the imbalance in bone metabolism, and increase bone formation, and is expected to provide a new strategy and method for the treatment of osteoporosis.

    More than 200 million people are affected by osteoporosis worldwide, as estimated by 2 million annual hip fractures and other debilitating bone fractures (vertebrae compression and Colles' fractures). Osteoporosis is a multi-factorial disease with potential contributions from genetic, endocrine functional, exercise related and nutritional factors. Of particular considerations are calcium (Ca) status, vitamin D, fluoride, magnesium and other trace elements. Several trace elements such as zinc and copper are essential for normal development of the skeleton in humans and animals. Fluoride accumulates in new bone and results in a net gain in bone mass, but may be associated with a tissue of poor quality. Aluminum induces impairment of bone formation. Gallium and cadmium suppresses bone turnover. However, exact involvements of the trace elements in osteoporosis have not yet been fully clarified. Numerous investigators have evaluated the role of medications and supplementations with minerals and trace substances to reverse the progression of this disease. Although bisphosphonates are still the drugs of choice, low-dosed fluoride and strontium salts have shown promise for the future. PMID:22575536

    To compare the efficacy and safety of nandrolone decanoate and calcium (NDC) with those of calcium alone (CAL) in men with idiopathic osteoporosis, a 12-month, randomized, prospective, controlled study, was performed in an outpatient clinic. Twenty-one men with idiopathic osteoporosis (as determined by radiological and dual energy x-ray absorptiometry findings) were randomly allocated to either 50 mg nandrolone decanoate intramuscularly (im) weekly and 1,000 mg oral calcium carbonate daily (NDC group) or to 1,000 mg oral calcium carbonate daily (CAL group). Bone densitometry (total body, left femur, and lumbar spine), serum, and urine biochemical parameters were measured at 3-month intervals. In the NDC group, bone mineral density initially increased, reached a plateau, and then decreased to near baseline levels at 12 months. Increases in lean muscle mass mirrored these changes. Free and total testosterone significantly decreased. Hemoglobin increased in all patients in this group. Patients in the CAL group exhibited no significant change in either total body or bone mineral density or biochemical parameters. Thus, nandrolone decanoate, 50 mg im weekly, transiently increases the bone mass of men with idiopathic osteoporosis in this preliminary study. Careful monitoring is necessary. PMID:10099043

    Osteoporosis is one of the most common disorders in postmenopausal women, affecting the quality of life and increasing the risk for fractures in minor traumas. Changes in the bone microarchitecture causes static changes in the body and affects motility. In this study, we analyzed two groups of women, one with physiological menopause and one with surgically induced menopause. The diagnosis of osteoporosis was suspected based on the clinical symptoms and confirmed by assessing bone mineral density by the dual-energy X-ray absorptiometry (DEXA). Comparing some clinical and biological aspects there was noted that a much higher percentage of women with surgically induced menopause exhibited increases in body mass index, changes in serum lipids, cholesterol, triglycerides, blood glucose, serum calcium, magnesemia and osteocalcin. In contrast, no significant differences were observed in the histopathological aspects of bone tissue examined from these two groups. In all patients, there was identified a significant reduction in the number of osteocytes and osteoblasts, the expansion of haversian channels, reducing the number of trabecular bone in the cancellous bone with wide areola cavities often full of adipose tissue, non-homogenous demineralization of both the compact bone and the cancellous bone, atrophy and even absence of the endosteal, and the presence of multiple microfractures. Our study showed that early surgically induced menopause more intensely alters the lipid, carbohydrate and mineral metabolism, thus favoring the onset of osteoporosis. PMID:27151697

    Introduction Low trauma fractures due to osteoporosis are a major health concern worldwide. Despite the availability of many therapeutic compounds to reduce fracture risk, osteoporosis remains undertreated and the burden of osteoporotic fractures remains high. Denosumab is a novel agent that acts to reduce bone turnover, improve bone mineral density, and reduce fracture risk, offering a favorable efficacy and safety profile. Areas covered This review covers the pharmacology and major clinical trials with extension/post-marketing follow-up, including trials for all FDA-approved indications of denosumab to date. Expert Opinion Denosumab is an efficacious and safe osteoporosis treatment option, with current data up to 8 years of continued use showing continued improvement in bone density with sustained fracture risk reduction. Safety profiles overall are similar to placebo, with no new safety concerns in extension trials, though a theoretical increased risk of infection exists with RANKL inhibition. Future considerations include safety of prolonged treatment beyond 8 years, and efficacy/fracture risk after discontinuation or with non-adherence, given the characteristic pharmacodynamic profile of denosumab.

  19. Safety considerations with bisphosphonates for the treatment of osteoporosis.

    Bisphosphonates are the most commonly prescribed medications for the treatment of osteoporosis. Although evidence supports a good safety profile for these agents, numerous tolerability issues have been associated with their use. This review provides an overview of the safety issues associated with the nitrogen-containing class of bisphosphonates and discusses the potential effect of these issues on adherence. The review specifically considers upper gastrointestinal (UGI) adverse events (AEs), renal toxicity, influenza-like illness, osteonecrosis of the jaw and evidence on how to treat or prevent these events. In clinical trials, UGI AEs, including severe events such as oesophageal ulcer, oesophagitis and erosive oesophagitis, have been reported at similar frequencies in placebo- and active-treatment arms. However, postmarketing studies have highlighted UGI AEs as a concern. These studies show that a significant portion of patients are less compliant with administration instructions outside strict clinical trial supervision, and when oral bisphosphonates are not administered as directed, patients are more likely to experience UGI AEs. Some clinical trials with oral bisphosphonates have suggested that a decrease in the frequency of administration may lead to improvement in gastrointestinal tolerability. In the authors' experience, the issue of UGI tolerability can be minimised by explaining to the patient and/or caregiver the importance of following administration instructions. Intravenous (IV) bisphosphonates have been recently approved for use in osteoporosis, offering an alternative regimen for patients with osteoporosis. Earlier generation IV bisphosphonates (e.g. etidronate) have been associated with acute renal failure. Alternatively, late-generation IV bisphosphonates (i.e. ibandronate) have shown a better safety profile in relation to renal toxicity. Influenza-like illness, often referred to as an acute-phase reaction, covers symptoms such as fatigue, fever

    A novel strontium salt compound strontium fructose 1, 6-diphosphate (FDP-Sr) has been proved to have highly effective for bone loss via dual effects of stimulating bone formation and suppressing bone absorption. In the present study, metabolomic approach was used to identify and study potential biomarkers associated with the effect and safety of FDP-Sr. The metabolomic profiles of bone loss induced by estrogen deficiency in a rat model was described to attain a system-level map of the shift on the metabolic response in plasma using GC/TOF-MS, after FDP-Sr was orally administered at the dose of 110 mg/kg/day for the prevention and 220 mg/kg/day for the treatment. Meanwhile, bone turnover biomarkers and bone mineral density were investigated to identify the specific changes of potential anti-osteoporosis effects of FDP-Sr. The differences in metabolic profiles between osteoporosis rats and FDP-Sr treated rats were well observed by the partial least squares-discriminant analysis (PLS-DA) to the MS spectra. Some metabolites including homocysteine, arachidonic acid, alanine, and hydroxyproline, which significantly changed during osteoporosis progression could be effectively reversed after FDP-Sr therapy. Of course some metabolites such as uric acid, glyceric acid, octadecadienoic acid, docosahexaenoic acid, oleic acid, and hexadecanoic acid were not found to reverse significantly after FDP-Sr administration. These results delineated the FDP-Sr effects-related metabolic alterations in the bone loss rats, suggesting that metabonomic analysis could provide helpful information on the new potential biomarkers relating to the mechanism of anti-osteoporosis action and side effects of FDP-Sr against estrogen deficiency induced bone loss.

    Epidemic rates of osteoporosis in the western world have yielded intense efforts to develop management approaches to combat this potentially devastating disorder; recent research has unveiled innovative strategies which hold considerable promise for prevention of skeletal compromise and amelioration of suboptimal bone health. According to many algorithms and practice directives, the contemporary assessment and management of osteoporosis focuses heavily on determination of fracture risk and pharmaceutical intervention for those patients deemed to be at high risk. While routine recommendations for calcium and vitamin D have been incorporated into most regimens, disproportionately little attention has been given to recent research elucidating improved bone health and diminution in fracture rates experienced by patients receiving specific nutrients. In mainstream medical practice, clinical analysis and management of nutritional or dietary issues is sometimes perceived as unconventional, primitive or unsophisticated health care. Recent evidence-based research, however, supports intervention with adequate amounts of specific nutrients including vitamin D, strontium, vitamin K, and essential fatty acids in the prevention and primary management of osteoporosis.

    Imbalance of bone resorption and bone formation is responsible for osteoporosis that is characterized by decreased bone mass and mineral density. The aim of this study was to evaluate the available data that could clarify the effectiveness and safety of supplementations with calcium and vitamin D, alone or in combination, to slow down bone loss in postmenopausal and elderly women. Using search key words, we performed a research both in the PubMed and Cochrane Library in order to find all meta-analysis, prospective and randomized clinical studies published from 2000 to 2014 that had investigated the effectiveness of calcium and vitamin D in the treatment of osteoporosis. At the moment it is not possible either to provide reassurance that calcium supplements given with vitamin D do not cause adverse cardiovascular events or to link them with certainty to increased cardiovascular risk. According to the data now available, vitamin D, at dosage of at least 800 IU/day, alone or in combination with antiresorptive drugs, should be administered in osteoporotic and osteopenic patients for a primary and secondary prevention. Further studies are needed and the debate remains ongoing. However, every administration needs the calculation of the absolute fracture risk of the patient. Especially considering the high cost of osteoporosis prevention, more studies are mandatory to clarify indications and contraindications. PMID:26205648

    2014-01-01

    Background Osteoporosis poses a significant public health issue. It is a skeletal disorder characterized by compromised bone strength that predisposes to increased risk of fracture. There is a direct relationship between the lack of estrogen after menopause and the development of osteoporosis. About 33% of women over 50 will experience bone fractures as a result of osteoporosis. Nigella Sativa (NS) has been shown to have beneficial effects on bone and joint diseases. The present study was conducted to elucidate the protective effect of Nigella Sativa on osteoporosis produced by ovariectomy in rats. Methods Female Wistar rats aged 12–14 months were divided into three groups: sham-operated control (SHAM), ovariectomized (OVX), and ovariectomized supplemented with nigella sativa (OVX-NS) orally for 12 weeks; 4 weeks before ovariectomy and 8 weeks after. After 12 weeks, plasma levels of calcium (Ca+2), phosphorous (Pi), alkaline phosphatase (ALP), amino terminal collagen type 1 telopeptide, malondialdehyde (MDA), nitrates, nitric oxide surrogate, tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6) were measured. Histological examination of the liver and the tibia was conducted. Histomorphometric analysis of the tibia was also performed. Results OVX rats showed significant decrease in plasma Ca+2, accompanied by a significant increase in plasma ALP, amino terminal collagen type 1 telopeptide, MDA, nitrates, TNF-α and IL-6. These changes were reversed by NS supplementation in OVX-NS group to be near SHAM levels. Histological examination of the tibias revealed discontinuous eroded bone trabeculae with widened bone marrow spaces in OVX rats accompanied by a significant decrease in both cortical and trabecular bone thickness compared to Sham rats. These parameters were markedly reversed in OVX-NS rats. Histological examination of the liver showed mononuclear cellular infiltration and congestion of blood vessels at the portal area in OVX rats which were not found

    Osteoporosis is a skeletal disease associated with an imbalance between formation and resorption, leading to net loss of bone mass, loss of bone microarchitecture, and development of fractures. Bone resorption is primarily due to an activation of osteoclastogenesis and an increase in receptor activator of nuclear factor kappa-B ligand (RANKL) expression, a cytokine involved in the final pathway of the osteoclast cycle.Recent studies of genetic diseases led to the discovery of the wingless-type (Wnt) signaling pathway that plays a major role in bone formation. Further work showed that sclerostin produced by osteocytes and the Dickkopf (DKK1) protein secreted in bone were negative regulators of the Wnt signaling bone formation pathway that act directly by binding to the co-receptors LRP5 and LRP6 of WnT and thereby inhibiting the anabolic Wnt pathway. This understanding of the bone remodeling led to the discovery of new biological drugs that target these pathways and have been evaluated in clinical trials.The current article discusses the role of these newer "biological" agents in management of osteoporosis. Denosumab, a human monoclonal antibody that specifically binds RANKL, blocks the binding of RANK to its ligand markedly reducing bone resorption, increases bone density, and reduces fractures and is approved for osteoporosis. Parathyroid hormone PTH 1-34 (teriparatide) stimulates bone formation through inhibition of sclerostin, DKK1, and frizzled protein; increases BMD; improves microarchitecture; and decreases fractures and is approved for osteoporosis. The anti-sclerostin antibodies (romosozumab, blosozumab) increase bone mass by neutralizing the negative effects of sclerostin on the Wnt signaling pathway. These biologics are being evaluated now in a clinical trial and early data looks promising. Cathepsin K is a proteolytic enzyme that degrades bone matrix and inhibitors such as odanacatib show increasing bone density and perhaps decreased fractures. The

    Osteoporosis is a major cause of morbidity in older people. There are a large number of risk factors for the development of senile osteoporosis. However, recent discoveries suggest that these risk factors could exert their effects through immunologically mediated modulation of bone remodelling. Inflamm-ageing itself plays a role in bone remodelling through pro-inflammatory cytokines, which are known to influence osteoclasts and osteoblasts, together with other more recently discovered immunological mediators and transcription factors. Senile osteoporosis is an example of the central role of immune-mediated inflammation in determining bone resorption. In this review, we will discuss the pathogenesis of osteoporosis in the context of immunosenescence. PMID:17109066

    Osteoporosis is characterized by systemic impairment of bone mass, strength, and microarchitecture, resulting in increased risk for fragility fracture, disability, loss of independence and even death. Adequate nutrition is important in achieving and maintaining optimal bone mass, as well as preventing this debilitating disease. It is widely accepted that adequate calcium and vitamin D intake are necessary for good bone health; however, nutritional benefits to bone go beyond these two nutrients. This review article will provide updated information on all nutrients and foods now understood to alter bone health. Specifically, this paper will focus on related research from the Framingham Osteoporosis Study, an ancillary study of the Framingham Heart Study, with data on more than five thousand adult men and women.

    We describe a 33-year old man suffering from severe vertebral osteoporosis and urticaria pigmentosa due to systemic mast cell disease (SMCD). Because i.v. clodronate therapy could not prevent further vertebral fractures, an additional treatment with interferon alpha-2b was initiated. During 24 months of treatment, our patient had no further pain episodes, no new vertebral fractures were discovered, trabecular bone mineral density (BMD) increased significantly and urticarial symptoms improved. Nevertheless, the extent of skin lesions remained unchanged. On histological examination, a remarkable decrease of mast cells was observed in the bone marrow, but not in the skin. Five months after discontinuation of interferon alpha-2b, trabecular BMD decreased and urticarial symptoms deteriorated. These findings illustrate a beneficial effect of interferon alpha-2b on SMCD-induced osteoporosis as well as urticarial symptoms, and raise the question whether this treatment may have a diverse impact on mast cell population in different tissues.

    Effective prevention and management of osteoporosis would require suitable methods for population screenings and early diagnosis. Current clinically-available diagnostic methods are mainly based on the use of either X-rays or ultrasound (US). All X-ray based methods provide a measure of bone mineral density (BMD), but it has been demonstrated that other structural aspects of the bone are important in determining fracture risk, such as mechanical features and elastic properties, which cannot be assessed using densitometric techniques. Among the most commonly used techniques, dual X-ray absorptiometry (DXA) is considered the current “gold standard” for osteoporosis diagnosis and fracture risk prediction. Unfortunately, as other X-ray based techniques, DXA has specific limitations (e.g., use of ionizing radiation, large size of the equipment, high costs, limited availability) that hinder its application for population screenings and primary care diagnosis. This has resulted in an increasing interest in developing reliable pre-screening tools for osteoporosis such as quantitative ultrasound (QUS) scanners, which do not involve ionizing radiation exposure and represent a cheaper solution exploiting portable and widely available devices. Furthermore, the usefulness of QUS techniques in fracture risk prediction has been proven and, with the last developments, they are also becoming a more and more reliable approach for assessing bone quality. However, the US assessment of osteoporosis is currently used only as a pre-screening tool, requiring a subsequent diagnosis confirmation by means of a DXA evaluation. Here we illustrate the state of art in the early diagnosis of this “silent disease” and show up recent advances for its prevention and improved management through early diagnosis. PMID:24349644

    Introduction: Osteoporosis is a form of dysmetabolic osteopathy of multifactorial origin, characterised by reduction of the bone matrix and mineral portion and, overall, of bone mass, leading to fragility and increased fracture risk. AETIOPATHOGENESIS -ENDOCRINE FACTORS: ACTH, glycocorticoids, PTH, thyroxine, oestrogen, testosterone-GENETIC FACTORS: Major genes that regulate fundamental characteristics of bone, such as density and quality, and minor genes that regulate individual genetic background [lipoprotein receptor related protein (LRP5), TGF1, BMP, VDR, COL1A1, ER]. The DIAGNOSIS is based on history, clinical findings (vertebral or appendicular fractures), blood chemistry, conventional radiology and bone mass measurement. For the latter, it is possible to use DUAL-ENERGY X-RAY DENSITOMETRY which measures bone mineral content: according to the WHO definition, in osteoporosis bone mineral density (BMD) is more than 2.5 standard deviations below normal. MAXILLARY OSTEOPOROSIS: because of their function as a support for teeth, which leads to the development of the alveolar process, and their role in mastication, the jawbones (maxilla and mandible) differ from all the other bones of the skeleton. This role, also involving the masticatory muscles, prompts bone trophism. In advancing age a marked reduction of the thickness of the maxillary cortical bone is observed, together with increased porosity and constant functional remodelling of the trabecular part, a phenomenon that, as it increases, leads to tooth loss. Only a mandibular area (a bucco-lingual area of cortical bone in front of the mental foramen) remains unmodified, independently of gender, age and tooth loss. Materials and methods: Kemifar® supplies a test which can be used to study several factors (Er, VDR, COL1A1) that predispose to the development of osteoporosis. OsteoResis®Type is a simple, non-invasive test that allows the complete determination, and interpretation, of several genotypes associated

    One of the difficulties associated with commercial layer production is the development of osteoporosis in hens late in the production cycle. In light of this fact and because of hens' unique requirements for Ca, many studies have focused on the regulation of Ca and the role of estrogen in this process. The time course of estrogen synthesis over the productive life of hens has been well documented; increased circulating estrogen accompanies the onset of sexual maturity while decreases signal a decline in egg production prior to a molt. Numbers of estrogen receptors decrease with age in numerous tissues. The parallel changes in calcium-regulating proteins, primarily Calbindin D28K, and in the ability of duodenal cells to transport Ca, are thought to occur as a result of the changes in estrogen, and are also reversible by the molt process. In addition to the traditional model of estrogen action, evidence now exists for a possible nongenomic action of estrogen via membrane-bound receptors, demonstrated by extremely rapid surges of ionized Ca in chicken granulosa cells in response to 17beta-estradiol. Estrogen receptors have also been discovered in duodenal tissue, and tamoxifen, which binds to the estrogen receptor, has been shown to cause a rapid increase in Ca transport in the duodenum. In addition, recent evidence also suggests that mineralization of bone per se may not explain entirely the etiology of osteoporosis in the hen but that changes in the collagen matrix may contribute through decreases in bone elasticity. Taken together, these studies suggest that changes in estrogen synthesis and estrogen receptor populations may underlie the age-related changes in avian bone. As with postmenopausal women, dietary Ca and vitamin D are of limited benefit as remedies for osteoporosis in the hen. PMID:14979570

Recent findings Numerous studies support the concept of a bone–muscle unit, where constant cross-talking between the two tissues takes place, involving molecules released by the skeletal muscle secretome, which affects bone, and osteokines secreted by the osteoblasts and osteocytes, which, in turn, impact muscle cells. Summary New chemical entities aiming at concomitantly treating osteoporosis and sarcopenia could be developed by targeting pathways that centrally regulate bone and muscle or emerging pathways that facilitate the communication between the two tissues.

    Objective There is growing evidence that fracture risk is increased in individuals with HIV and/or hepatitis C virus (HCV) infection. We systematically reviewed the literature to determine whether prevalence of osteoporosis and incidence of fracture is increased in HIV/HCV-coinfected individuals. Design A systematic review and meta-analysis. Methods A search was performed of Medline, Scopus and the Cochrane Library databases, as well as of abstracts from annual retroviral, liver and bone meetings (up to 2013) for studies with bone mineral density (BMD) or bone fracture data for HIV/HCV-coinfected individuals. Osteoporosis odds ratios (ORs) and fracture incidence rate ratios (IRRs) were estimated from studies with data on HIV-monoinfected or HIV/HCV-uninfected comparison groups. Results Of 15 included studies, nine reported BMD data and six reported fracture data. For HIV/HCV-coinfected, the estimated osteoporosis prevalence was 22% [95% confidence interval (95% CI) 12–31] and the crude OR for osteoporosis compared with HIV-monoinfected was 1.63 (95% CI 1.27–2.11). The pooled IRR of overall fracture risk for HIV/HCV-coinfected individuals was 1.77 (95% CI 1.44–2.18) compared with HIV-monoinfected and 2.95 (95% CI 2.17–4.01) compared with uninfected individuals. In addition to HIV/HCV-coinfection, older age, lower BMI, smoking, alcohol and substance use were significant predictors of osteoporosis and fractures across studies. Conclusion HIV/HCV coinfection is associated with a greater risk of osteoporosis and fracture than HIV monoinfection; fracture risk is even greater than uninfected controls. These data suggest that HIV/HCV-coinfected individuals should be targeted for fracture prevention through risk factor modification at all ages and DXA screening at age 50. PMID:24977441

Among numerous possible causes for such secondary osteoporosis, the author has selected osteogenesis imperfecta (OI), osteoporosis associated with gastrectomy or bariatric surgery, inflammatory bowel diseases (IBD), and chronic obstructive pulmonary disease (COPD). For OI, current standard treatment is bisphosphonates (BPs), of which efficacy for fracture inhibition has recently been of issue. Other treatment modalities, e.g. PTH, have just been explored. Osteoporosis associated with gastrectomy, bariatric surgery or IBD, have been treated with vitamin D, calcium, and BPs.

    Toxqui, Laura; Vaquero, M. Pilar

    2015-01-01

    Iron is essential in oxygen transport and participates in many enzymatic systems in the body, with important roles in collagen synthesis and vitamin D metabolism. The relationship between iron and bone health comes from clinical observations in iron overload patients who suffered bone loss. The opposite scenario—whether iron deficiency, with or without anemia, affects bone metabolism—has not been fully addressed. This is of great interest, as this nutrient deficiency is a worldwide public health problem and at the same time osteoporosis and bone alterations are highly prevalent. This review presents current knowledge on nutritional iron deficiency and bone remodeling, the biomarkers to evaluate iron status and bone formation and resorption, and the link between iron and bone metabolism. Finally, it is hypothesized that chronic iron deficiency induces bone resorption and risk of osteoporosis, thus complete recovery from anemia and its prevention should be promoted in order to improve quality of life including bone health. Several mechanisms are suggested; hence, further investigation on the possible impact of chronic iron deficiency on the development of osteoporosis is needed. PMID:25849944

    Antrodia camphorata has previously demonstrated the efficacy in treating cancer and anti-inflammation. In this study, we are the first to evaluate Antrodia camphorata alcohol extract (ACAE) for osteoporosis recovery in vitro with preosteoblast cells (MC3T3-E1) and in vivo with an osteoporosis mouse model established in our previous studies, ovariectomized senescence accelerated mice (OVX-SAMP8). Our results demonstrated that ACAE treatment was slightly cytotoxic to preosteoblast at 25 μg/mL, by which the osteogenic gene expression (RUNX2, OPN, and OCN) was significantly upregulated with an increased ratio of OPG to RANKL, indicating maintenance of the bone matrix through inhibition of osteoclastic pathway. Additionally, evaluation by Alizarin Red S staining showed increased mineralization in ACAE-treated preosteoblasts. For in vivo study, our results indicated that ACAE inhibits bone loss and significantly increases percentage bone volume, trabecular bone number, and bone mineral density in OVX-SAMP8 mice treated with ACAE. Collectively, in vitro and in vivo results showed that ACAE could promote osteogenesis and prevent bone loss and should be considered an evidence-based complementary and alternative medicine for osteoporosis therapy through the maintenance of bone health.

    Drynariae rhizoma has been used to prevent bone loss that occurs with increasing age. However, the chemical compounds in extracts that act on bone metabolism in herbal medicine are poorly understood. This study aimed to investigate and compare the extraction efficacy of polyphenolic compounds, antioxidant activity, and in vitro anti-osteoporosis properties of water extract (DR-DW) and ethanol extract (DR-EtOH) from D. rhizoma. Total phenolics and flavonoids were better extracted with 70% EtOH, and this extraction method also resulted in higher antioxidant activity and in vitro anti-osteoporosis properties in these extracts. In particular, the contents of phloroglucinol, protocatechuic acid ethyl ester, 2-amino-3,4-dimethyl-benzoic acid, 3-(3,5-dimethyl-pyrazol-1-yl)-benzoic acid, chlorogenic acid, syringic acid, trans-ferulic acid, (-)-epigallocatechin, epigallocatechin gallate, quercetin dehydrate, luteolin and emodin in DR-EtOH were higher than those in DR-DW. These results indicated that DR-EtOH could be a good source of natural herbs with anti-osteoporosis properties. PMID:24763116

    Osteoporosis is a well-established extra-articular feature of Rheumatoid Arthritis (RA). Systemic inflammation seems to play a crucial role in causing an alteration of multiple homeostatic systems implied in bone health, such as the RANK/RANKL/Osteoprotegerin and Wnt/β catenin pathways; several other causal factors have been called into question, including the chronic use of corticosteroids. Since vitamin D exerts important immune-regulatory roles, it has been claimed that derangement of the vitamin D/parathyroid hormone (PTH) system, a well-known determinant of bone health, may play a pathogenic role in autoimmunity; animal models and clinical data support this hypothesis. Furthermore, RA patients seem to be relatively refractory to vitamin D-induced PTH suppression. Therefore, the link between RA and osteoporosis might in part be due to alterations in the vitamin D/PTH system. A better understanding of the pathophysiology of this system may be crucial to prevent and cure osteoporosis in patients with inflammatory/autoimmune diseases. A major clinical correlate of the strict cooperation and interdependence between vitamin D and PTH is that correction of the vitamin D deficiency, at least in autoimmune diseases, should be targeted to PTH suppression.

    The increasing importance of preventive measures in the field of orthopedics and trauma surgery becomes apparent because of the demographic changes and the high risk for secondary fractures following osteoporotic fractures. Within the fracture treatment chain, orthopedics and trauma surgery are in the "pole position" to initiate these measures in geriatric patients. In the past orthopedists and trauma surgeons have constantly accused of neglecting secondary fracture prevention in fragility fracture patients. There are several reasons that speak in favor of us undertaking a role in secondary fracture prevention: osteoporosis medication is highly effective in fracture prevention when correctly indicated, the positive effects of osteoporosis therapy on fracture healing and legal issues. Arguments that have been used to justify neglect of secondary fracture prevention are undesired side effects related to osteoporosis medications, such as atypical femoral fractures and osteonecrosis of the jaws, interference of some specific drugs with fracture healing and the working conditions in emergency departments. These run contrary to the consideration of chronic diseases such as osteoporosis, secondary osteoporosis and the underlying disease could be overlooked and the increasing complexity of medicinal osteoporosis therapy. In the first part of the article these arguments are weighed against each other. In the second part the concept of a fracture liaison service (FLS) is discussed. The FLS framework now allows an active role to be taken with respect to secondary fracture prevention despite the busy daily routine schedule. Implementation of an FLS is facilitated by dedicated instruction protocols and programs. Self-financing of an FLS is currently possible only in some specific healthcare systems. In healthcare systems in German-speaking areas a cross-financing must be available and the value of an FLS indirectly presented. Apart from the financial aspects, implementation of

    Osteoporosis and sarcopenia are common in older age and associated with significant morbidity and mortality. Consequently, they are both attended by a considerable socioeconomic burden. Osteoporosis was defined by the World Health Organisation (WHO) in 1994 as a bone mineral density of less than 2.5 standard deviations below the sex-specific young adult mean and this characterisation has been adopted globally. Subsequently, a further step forward was taken when bone mineral density was incorporated into fracture risk prediction algorithms, such as the Fracture Risk Assessment Tool (FRAX®) also developed by the WHO. In contrast, for sarcopenia there have been several diagnostic criteria suggested, initially relating to low muscle mass alone and more recently low muscle mass and muscle function. However, none of these have been universally accepted. This has led to difficulties in accurately delineating the burden of disease, exploring geographic differences, and recruiting appropriate subjects to clinical trials. There is also uncertainty about how improvement in sarcopenia should be measured in pharmaceutical trials. Reasons for these difficulties include the number of facets of muscle health available, e.g. mass, strength, function, and performance, and the various clinical outcomes to which sarcopenia can be related such as falls, fracture, disability and premature mortality. It is imperative that a universal definition of sarcopenia is reached soon to facilitate greater progress in research into this debilitating condition.

    This study evaluated whether growing rats were appropriate animal models of glucocorticoid-induced osteoporosis. The 3-month-old male rats were treated with either vehicle or prednisone acetate at 1.5, 3.0, and 6.0 mg/kg/day by oral gavage, respectively. All rats were injected with tetracycline and calcein before sacrificed for the purpose of double in vivo labeling. Biochemistry, histomorphometry, mechanical test, densitometry, micro-CT, histology, and component analysis were performed. We found that prednisone treatments dose dependently decreased body weight, serum biomarkers, biomechanical markers, bone formation, and bone resorption parameters in both tibial and femoral trabecular bone without trabecular bone loss. We also found that significant bone loss happened in femoral cortical bone in the glucocorticoid-treated rats. The results suggested that prednisone not only inhibited bone formation, but also inhibited bone resorption which resulted in poor bone strength but with no cancellous bone loss in growing rats. These data also suggested that the effects of glucocorticoid on bone metabolism were different between cortical bone and trabecular bone, and different between tibia and femur. Growing rats may be a glucocorticoid-induced osteoporosis animal model when evaluated the effects of drugs upon juvenile patients exposed to GC for a long time. PMID:25086673

    The skeleton is a metabolically active organ undergoing continuously remodelling. With ageing and menopause the balance shifts to increased resorption, leading to a reduction in bone mineral density and disruption of bone microarchitecture. Bone mass accretion and bone metabolism are influenced by systemic hormones as well as genetic and lifestyle factors. The classic paradigm has described osteoporosis as being a "brittle bone" disease that occurs in post-menopausal, thin, Caucasian women with low calcium intakes and/or vitamin D insufficiency. However, a study of black women in Africa demonstrated that higher proportions of body fat did not protect bone health. Isoflavone interventions in Asian postmenopausal women have produced inconsistent bone health benefits, due in part to population heterogeneity in enteric bacterial metabolism of daidzein. A comparison of women and men in several Asian countries identified significant differences between countries in the rate of bone health decline, and a high incidence rate of osteoporosis in both sexes. These studies have revealed significant differences in genetic phenotypes, debunking long-held beliefs and leading to new paradigms in study design. Current studies are now being specifically designed to assess genotype differences between Caucasian, Asian, African, and other phenotypes, and exploring alternative methodology to measure bone architecture.

    To be optimal, the treatment of osteoporosis must be global, including nonpharmacological measures. At the initiation of the treatment, a personalized evaluation of the patient must be realized on diet, physical activity, risk of fall and adhesion of the patient. Dietary calcium is estimated and advices given to attain 1000 in 1200 mg/day and limit excessive coffee, soft drinks and salt intake. Dietary calcium is recommended, but if it is impossible, a complement is prescribed, adapted to the intensity of the deficiency. Serum 25-(OH)-vitamine D is measured and, if below 30 ng/ml, a supplementation prescribed. Low protein intake is looked for and corrected if necessary. Advises are given to limit the alcohol to 2 units/day, stop smoking and to have a regular and high impact physical activity. Subjects at risk of fall must be identified and risk factors corrected if possible. Dental recommandations for the use of bisphosphonates in osteoporosis must be apply. Finally, patient education could be used to optimize patient adherence to pharmacological and non pharmacological anti-osteoporotic treatments. PMID:22408863

  16. QUS devices for assessment of osteoporosis

    2002-05-01

    The acronym QUS (Quantitative Ultrasound) is now widely used to describe ultrasound assessment of osteoporosis, a disease primarily manifested by fragility fractures of the wrist and hip along with shortening of the spine. There is currently available a plethora of commercial QUS devices, measuring various anatomic sites including the heel, finger, and tibia. Largely through commercial rather than scientific drivers, the parameters reported often differ significantly from the two fundamental parameters of velocity and attenuation. Attenuation at the heel is generally reported as BUA (broadband ultrasound attenuation, the linearly regressed increase in attenuation between 200 and 600 kHz). Velocity derivatives include bone, heel, TOF, and AdV. Further, velocity and BUA parameters may be mathematically combined to provide proprietary parameters including ``stiffness'' and ``QUI.'' In terms of clinical utility, the situation is further complicated by ultrasound being inherently dependent upon ``bone quality'' (e.g., structure) in addition to ``bone quantity'' (generally expressed as BMD, bone mineral density). Hence the BMD derived WHO criteria for osteoporosis and osteopenia may not be directly applied to QUS. There is therefore an urgent need to understand the fundamental dependence of QUS parameters, to perform calibration and cross-correlation studies of QUS devices, and to define its clinical utility.

    Osteoporosis is an aging problem. The declining bone mineral density (BMD) enhances the chances of fractures during minor falls. Effective pharmaceuticals are available for a rapid improvement of BMD. However, hormonal treatment gives serious complications, and bisphosphonates may lead to odd fractures of long bones, resulting from excessive rigidity of the cortical components. Many medicinal herbs used in Traditional Chinese Medicine, known as kidney tonics, have been tested for their effects on bone metabolism in the laboratory and clinically. Three of these, viz. Herba epimedii (, Yín Yáng Huò), Fructus ligustri lucidi (, Nǚ Zhēn Zi), and Fructus psoraleae (, Bǔ Gǔ Zhī) were chosen to form a herbal formula, ELP. ELP was tested on in vitro platforms and was shown to have both osteoblastic and anti- osteoclastic action. ELP tested on ovariectomized rats also showed BMD protection. ELP was then put on a placebo- controlled randomized clinical trial. BMD protection was obvious among those women with the onset of menopause beyond 10 years (P < 0.05). A general protective trend was observed among all women under trial (P > 0.05). Although a thorough literature review on the herbal treatment effects did not give convincing answers to the use of Chinese herbs in osteoporosis, our study supports more research and trials in this area, while we are looking for safe and effective agents to keep the bone metabolism in a balanced state.

  18. Idiopathic osteoporosis: an evolutionary dys-adaptation?

    Osteoporosis is characterised by simultaneous net bone growth and net resorption on different surfaces, suggesting that systemic factors are not the sole explanation for the findings. The main clinical consequence is fracturing in the largely trabecular bones of the spine, hip, and radius, and the key problem in these areas is finding an explanation for the preferential loss of transverse trabeculae. In normal bone, local maintenance depends on a negative feedback response to intermittent compression strain, and it is concluded, from biomechanical analysis of the response required to achieve negative feedback, that a preferential loss of transverse trabeculae is indicative of a selective deficiency of radial compression loading. The only significant source of radial compression in humans is the induced strain produced by axial tension. This is a necessary component of the lifestyles of quadrupeds and arboreal primates, but in humans occurs only on the convex side when the bone is offset loaded. The resulting strain is a function of the range of movement. It is suggested that the asymmetrical pattern of bone loss in cortical and trabecular osteoporosis reflects chronic underuse of movement range, resulting from the adoption of a bipedal lifestyle. Exercise regimens based on using the whole of the available movement range should better prepare the skeleton to adjust to other factors hostile to bone maintenance.

  19. The Role of Calcium in Osteoporosis

    Calcium requirements may vary throughout the lifespan. During the growth years and up to age 25 to 30, it is important to maximize dietary intake of calcium to maintain positive calcium balance and achieve peak bone mass, thereby possibly decreasing the risk of fracture when bone is subsequently lost. Calcium intake need not be greater than 800 mg/day during the relatively short period of time between the end of bone building and the onset of bone loss (30 to 40 years). Starting at age 40 to 50, both men and women lose bone slowly, but women lose bone more rapidly around the menopause and for about 10 years after. Intestinal calcium absorption and the ability to adapt to low calcium diets are impaired in many postmenopausal women and elderly persons owing to a suspected functional or absolute decrease in the ability of the kidney to produce 1,25(OH)2D2. The bones then become more and more a source of calcium to maintain critical extracellular fluid calcium levels. Excessive dietary intake of protein and fiber may induce significant negative calcium balance and thus increase dietary calcium requirements. Generally, the strongest risk factors for osteoporosis are uncontrollable (e.g., sex, age, and race) or less controllable (e.g., disease and medications). However, several factors such as diet, physical activity, cigarette smoking, and alcohol use are lifestyle related and can be modified to help reduce the risk of osteoporosis.

    Osteoporosis is a major public health concern. Substance abuse and psychosis may be risk factors, however frequency of screening and disease risk in women with psychotic disorders and substance use disorder (SUD) remains unknown. Methods This study examined rates (FY 2005) of osteoporosis screening and disease risk in Medicaid enrolled women aged 50 to 64 (N=18,953). Four diagnostic groups were characterized: 1) Psychosis; 2) SUD; 3) Major mood disorder and 4) Controls. The interaction of psychosis and SUD on screening and disease prevalence of osteoporosis was tested. Results The prevalence of osteoporosis across the entire population was 6.7%. Four percent of those without an osteoporosis diagnosis received osteoporosis screening with no notable differences between psychosis and controls. Those with SUD, however, had a significant reduction in screening compared to controls (OR=0.61, 95% CI 0.40–0.91, p=0.016). Women with a major mood disorder were more likely to have osteoporosis in their administrative record (OR=1.32, 95% CI=1.03–1.70, p=0.028) compared to controls. Those who were dually diagnosed (SUD and psychosis) in the oldest ages (55–64 years) had a markedly higher prevalence of osteoporosis compared to controls (OR=6.4 CI 1.51–27.6, p=0.012), whereas this interaction (SUD and psychosis) was not significant in the entire population over age 49. Conclusions Osteoporosis screening in the Medicaid population is significantly lower for women with SUD, after adjusting for age, race and Medicaid enrollment category. The prevalence of osteoporosis appears markedly elevated in those with major mood disorders and those over age 55 dually diagnosed with schizophrenia and SUD. PMID:20533029

    Introduction Osteoporosis as a chronic disease, affecting especially women in postmenopausal age, is an important, social and economic health problem especially of women of today's world. The aim of the study was to assess the level of knowledge of women in the peri- and postmenopausal period about the prevention of osteoporosis and show the influence of chosen risk factors on the level of this knowledge. Material and methods A group of 300 women aged 45-65, being patients of healthcare centres in Chełm, Lublin and Zamość (Lublin voivodeship, south-eastern Poland) were included in the study. The purposive sampling was used. Osteoporosis Knowledge Test (OKT) 2011 was the research tool. Gathered material was subjected to descriptive and statistical analysis. Tukey's test, t-student test and variance analysis (ANOVA) were all applied. An accepted p materiality level was < 0.05 and p < 0.01. Results Respondents presented the average level of knowledge about the role of physical activity in the prevention of osteoporosis (M = 13.93) and a low level of knowledge about well-balanced diet rich in calcium (M = 9.77). The knowledge about risk factors, screening and treatment remained on the average level (M = 8.00). An influence of socio-demographic factors on the level of knowledge was shown. Also some behaviours, associated with the lifestyle indeed influenced the level of this knowledge. Conclusions Professional educational programs on osteoporosis should be implemented in the population of Polish peri- and postmenopausal women. PMID:26327885

    Abstract In this study, we aimed to investigate the risk of osteoporosis in patients with erectile dysfunction (ED) by analyzing data from the Taiwan National Health Insurance Research Database (NHIRD). From the Taiwan NHIRD, we analyzed data on 4460 patients aged ≥40 years diagnosed with ED between 1996 and 2010. In total, 17,480 age-matched patients without ED in a 1:4 ratio were randomly selected as the non-ED group. The relationship between ED and the risk of osteoporosis was estimated using Cox proportional hazard regression models. During the follow-up period, 264 patients with ED (5.92%) and 651 patients without ED (3.65%) developed osteoporosis. The overall incidence of osteoporosis was 3.04-fold higher in the ED group than in the non-ED group (9.74 vs 2.47 per 1000 person-years) after controlling for covariates. Compared with patients without ED, patients with psychogenic and organic ED were 3.19- and 3.03-fold more likely to develop osteoporosis. Our results indicate that patients with a history of ED, particularly younger men, had a high risk of osteoporosis. Patients with ED should be examined for bone mineral density, and men with osteoporosis should be evaluated for ED. PMID:27368024

    Background and Objective. H. pylori infection causes a chronic inflammation in the gastric mucosa. However, this local inflammation may result in extra-digestive conditions. Our aim is to investigate the relationship between H. pylori infection and osteoporosis in Japan. Methods. This cross-sectional study was conducted among outpatients at the Juntendo University Hospital between 2008 and 2014. Participants for patient profile, H. pylori infection status, comorbidity, internal medical therapies, lumbar dual-energy X-ray absorptiometry (DXA), and bone turnover marker were collected and upper gastrointestinal endoscopy for reflux esophagitis, hiatal hernia, peptic ulcer disease (PUD), and endoscopic gastric mucosal atrophy (EGA) was performed. The diagnosis of osteoporosis was performed in accordance with the Japanese criteria. We investigated risk factors of osteoporosis. Results. Of the eligible 200 study subjects, 41 cases were of osteoporosis. Bivariate analysis showed that age, being female, BMI, alcohol, smoking, H. pylori, bone-specific ALP, PUD, and EGA were related to osteoporosis. Multivariate analysis showed that age (OR 1.13; 95%CI 1.07–1.20), being female (OR 4.77; 95%CI 1.78–12.77), BMI (OR 0.79; 95%CI 0.68–0.92), H. pylori (OR 5.33; 95%CI 1.73–16.42), and PUD (OR 4.98; 95%CI 1.51–16.45) were related to osteoporosis. Conclusions. H. pylori infection may be a risk factor of osteoporosis in Japan. PMID:25024699

    Large animal models are required for preclinical prevention and intervention studies related to osteoporosis research. The challenging aspect of this requirement is that no single animal model exactly mimics the progression of this human-specific chronic condition. There are pros and cons associated with the skeletal, hormonal, and metabolic conditions of each species that influence their relevance and applicability to human physiology. Of all larger mammalian species, nonhuman primates (NHPs) are preeminent in terms of replicating important aspects of human physiology. However, NHPs are very expensive, putting them out of reach of the vast majority of researchers. Practical, cost-effective alternatives to NHPs are sought after among ungulate (porcine, caprine, and ovine) and canine species that are the focus of this review. The overriding caveat to using large lower-order species is to take the time in advance to understand and appreciate the limitations and strengths of each animal model. Under these circumstances, experiments can be strategically designed to optimize the potential of an animal to develop the cardinal features of postmenopausal bone loss and/or yield information of relevance to treatment.

    Skeletal tissue undergoes continuous remodeling which makes it unique among other body tissues. Osteoporosis is a common bone metabolic disorder affecting both men and women. Osteoporosis and its complications mainly osteoporotic fractures, have a high impact on health and economy. Current approved medications are associated with numerous side effects, which limit their use. Identification of a new and safe therapy is mandatory. Statins, also known as HMGCoA reductase inhibitors, are frequently used for the treatment of hypercholesterolemia and for the prevention of morbidity and mortality associated with cardiovascular disease. Statins improved bone health status in intact and ovariectomised rodents following high clinically intolerable oral doses. However, this beneficial effect of statins could not be significantly demonstrated in humans. The reason behind this discrepancy might be due to the safety and bioavailability of the currently used oral statins. Vitamin E, especially the tocotrienols at the dose 60 mg/kg/day provided significant antiosteoporotic effects in different animal models of osteoporosis. The use of the aforementioned dose of tocotrienols was shown to be safe in both humans and animals. Enhancement of bone formation and reduction of bone resorption were achieved more effectively by a combination of tocotrienols and statins than by either treatment when supplemented separately at clinically tolerable doses. Therefore, the adverse effects associated with high statin doses might be avoided with the coadministration of tocotrienols. Moreover, the combination therapy strategy might be useful for patients who are at high risk of osteoporosis, cardiovascular events and hypercholesterolaemia. PMID:23848479

    A 1994 survey indicated that only 13 health authorities in the UK were purchasing access to dual X-ray absorptiometry (DXA), the most accurate measure of osteoporosis risk. By 1998 the number of centres (including private facilities providing DXA) was 161. All these were sent a questionnaire concerning their activities. 124 (77%) responded, and the survey found that DXA machines operate, on average, for only 3.6 days a week. Funding of and access to diagnostic services for osteoporosis varies greatly. There is clear scope for greater efficiency in the use of existing DXA machines and more equitable access to diagnostic services is required for effective management of osteoporosis. PMID:10700842

The prevalence of osteoporosis is greater in males, and increases with increasing patient age and disease duration. Osteoporosis is also more common in patients with syndesmophytes, cervical fusion, and peripheral joint involvement. These variables are not all independent, as they may be indicators of disease duration. Osteoporosis in patients with AS is largely confined to the axial skeleton, in contrast to the pattern of osteoporosis seen in rheumatoid arthritis. BMD at the lumbar spine and femoral neck may be severely reduced, while most studies indicate that carpal and radial BMD remain within normal limits. The development of syndesmophytes in late AS can lead to difficulties in the use of DEXA scanning to determine lumbar BMD, as the extraspinal bone may obscure osteoporotic vertebrae. Under these circumstances more accurate assessment of lumbar BMD, and one that correlates better with femoral neck BMD, may be obtained by quantitative CT scanning or DEXA scanning of the lateral aspect of the L3 vertebra. Osteoporosis in AS significantly increases the risk of vertebral compression fractures within 5 years of the diagnosis of AS. The risk of a vertebral compression fracture occurring over a 30 year period following the diagnosis of AS is 14%, compared to 3.4% for population controls. In patients with vertebral osteoporosis relatively minor trauma, such as slipping, can lead to spinal fracture and dislocatior with subsequent damage to the spinal cord. There is a higher incidence of spinal cord injury following spinal fracture dislocations in patients with AS, and the resulting neurological deficit can range from mild sensory loss to complete paraplegia. Cytokines such as TNF-alpha and IL-6 may play an important part in the pathogenesis of osteoporosis in early AS, and IL-6 levels have been correlated with markers of disease activity and severity. In late AS, mechanical factors

    This study aims to evaluate the effects of Remifemin (isopropanolic extract of Cimicifuga Racemosa) on postmenopausal osteoporosis. 120 female Sprague-Dawley rats were randomly assigned to four groups: sham surgery with vehicle, ovariectomy with vehicle, ovariectomy with estradiol valerate, or ovariectomy with Remifemin. Daily oral administrations of the vehicle, estradiol valerate, or Remifemin began 2 weeks after surgery and lasted to 4, 8, or 12 weeks. Ten rats in each group were sacrificed at each timestep with assessment of bone mineral density, trabecular bone structure, and biomechanical parameters of the femur and lumbar vertebra. Bone turnover markers were evaluated 12 weeks after surgery. Both drugs prevented bone density loss in the distal end of the femur and preserved the trabecular bone structure in both the lumbar vertebra and distal end of the femur following ovariectomy. Both drugs protected bone stiffness at the tested regions and reduced bone reabsorption in ovariectomized rats. The preventive effects of Remifemin against bone-loss can rival those of estradiol valerate if treatment duration is adequately extended. In conclusion, Remifemin may demonstrate equivalent effects to estradiol valerate in terms of preventing postmenopausal osteoporosis. PMID:24349369

    Progress continues to be made in the development of therapeutics for fracture prevention. Bisphosphonates are now available orally and intravenously, often as inexpensive generics, and remain the most widely used interventions for osteoporosis. The major safety concern associated with the use of bisphosphonates is the development of femoral shaft stress fractures and, although rare, this adverse event affords the principal rationale for restricting bisphosphonate therapy to those individuals with femoral T-scores <-2.5, and for providing drug holidays in those individuals requiring therapy for >5 years. Newer antiresorptive therapies, in the form of denosumab and cathepsin K inhibitors, might increase efficacy and possibly circumvent some of the safety concerns associated with bisphosphonate use (for example, gastrointestinal and renal complications). The combination of teriparatide with antiresorptives markedly increases effects on BMD; new anabolic agents are also very promising in this regard. However, whether or not these changes in BMD translate into improved efficacy of fracture prevention remains to be determined. Vitamin D is important for the prevention of osteomalacia, but does not influence BMD or fracture risk in patients not deficient in vitamin D. The balance of risks and benefits of calcium supplementation is contentious, but patients should be encouraged to adhere to a balanced diet aimed at maintaining a healthy body weight. Consideration of a patient's risk of falling, and its mitigation, are also important. In this Review, I summarize the short-term and long-term effects of osteoporosis therapies. PMID:25963272

    To investigate the correlation between postmenopausal osteoporosis (PMO) and the pathogenesis of periodontitis, ovariectomized rats were generated and the experimental periodontitis was induced using a silk ligature. The inflammatory factors and bone metabolic markers were measured in the serum and periodontal tissues of ovariectomized rats using an automatic chemistry analyzer, enzyme-linked immunosorbent assays, and immunohistochemistry. The bone mineral density of whole body, pelvis, and spine was analyzed using dual-energy X-ray absorptiometry and image analysis. All data were analyzed using SPSS 13.0 statistical software. It was found that ovariectomy could upregulate the expression of interleukin- (IL-)6, the receptor activator of nuclear factor-κB ligand (RANKL), and osteoprotegerin (OPG) and downregulate IL-10 expression in periodontal tissues, which resulted in progressive alveolar bone loss in experimental periodontitis. This study indicates that changes of cytokines and bone turnover markers in the periodontal tissues of ovariectomized rats contribute to the damage of periodontal tissues. PMID:24683547

    Premature menopause affects 1% of women under the age of 40, the usual age of the menopause is 51. Most women will present with irregular periods or no periods at all with or without climacteric symptoms. Around 10% of women present with primary amenorrhoea. A careful history and examination are required. It is important to ask specifically about previous chemotherapy or radiotherapy and to look for signs of androgen excess e.g. polycystic ovarian syndrome, adrenal problems e.g. galactorrhoea and thyroid goitres. Once pregnancy has been excluded, a progestagen challenge test can be performed in primary care. Norethisterone 5 mg tds po for ten days or alternatively medroxyprogesterone acetate 10 mg daily for ten days is prescribed. A withdrawal bleed within a few days of stopping the norethisterone indicates the presence of oestrogen and bleeding more than a few drops is considered a positive withdrawal bleed. The absence of a bleed indicates low levels of oestrogen, putting the woman at risk of CVD and osteoporosis. FSH levels above 30 IU/l are an indicator that the ovaries are failing and the menopause is approaching or has occurred. It should be remembered that FSH levels fluctuate during the month and from one month to the next, so a minimum of two measurements should be made at least four to six weeks apart. The presence of a bleed should not exclude premature menopause as part of the differential diagnosis as there can be varying and unpredictable ovarian function remaining. The progestagen challenge test should not be used alone, but in conjunction with FSH, LH and oestradiol. There is no treatment for premature menopause. Women desiring pregnancy should be referred to a fertility clinic and discussion of egg donation. Women not wishing to become pregnant should be prescribed HRT until the age of 50 to control symptoms of oestrogen deficiency and reduce the risks of osteoporosis and CVD. PMID:20408329

    Osteoporosis is a skeletal disorder characterized by low bone mineral density (BMD) and an increased susceptibility to fractures. Evidence from genetic studies indicates that BMD, a complex quantitative trait with a normal distribution, is genetically controlled. Genome-wide association studies (GWAS) as well as studies using candidate gene approaches have identified single-nucleotide polymorphisms (SNPs) that are associated with BMD, osteoporosis and osteoporotic fractures. These SNPs have been mapped close to or within genes including those encoding WNT/β-catenin signaling proteins. Understanding the genetics of osteoporosis will help to identify novel candidates for diagnostic and therapeutic targets. Genetic factors are also important for the development of sarcopenia, which is characterized by a loss of lean body mass, and obesity, which is characterized by high fat mass. Hence, in this review, we discuss the genetic factors, identified by genetic studies, which regulate the body components related to osteoporosis, sarcopenia, and obesity. PMID:25866211

    Osteoporosis is a common disease in which loss of bone mass results in skeletal fragility. The development of therapies for this disorder has been hampered by the lack of a convenient animal model. Here we describe a disorder in bone homeostasis in transgenic mice that inappropriately express the cytokine interleukin 4 (IL-4) under the direction of the lymphocyte-specific proximal promoter for the lck gene. Bone disease in lck-IL-4 mice appeared to result from markedly decreased bone formation by osteoblasts, features strikingly similar to those observed in cases of severe low-turnover human involutional osteoporosis. By 2 months of age, female and male lck-IL-4 mice invariably developed severe osteoporosis of both cortical and trabecular bone. Osteoporosis was observed in two independently derived founder animals, indicating that this phenotype was directly mediated by the IL-4 transgene. Images Fig. 1 Fig. 2 Fig. 3 PMID:8265598

    Electromagnetic fields (EMFs) as a safe, effective and noninvasive treatment have been researched and used for many years in orthopedics, and the common use clinically is to promote fracture healing. The effects of EMFs on osteoporosis have not been well concerned. The balance between osteoblast and osteoclast activity as well as the balance between osteogenic differentiation and adipogenic differentiation of bone marrow mesenchymal stem cells plays an important role in the process of osteoporosis. A number of recent reports suggest that EMFs have a positive impact on the balances. In this review, we discuss the recent advances of EMFs in the treatment of osteoporosis from basic research to clinical study and introduce the possible mechanism. In addition, we presented future perspectives of application of EMFs for osteoporosis. PMID:27356174

    Osteoporosis is a degenerative bone disease commonly related to aging. With an increase in life expectancies worldwide, the prevalence of the disease is expected to rise. Current clinical therapeutic treatments are not able to offer long-term solutions to counter the bone mass loss and the increased risk of fractures, which are the primary characteristics of the disease. However, the combination of bioactive nanomaterials within a biomaterial scaffold shows promise for the development of a localized, long-term treatment for those affected by osteoporosis. This review summarizes the unique characteristics of engineered nanoparticles that render them applicable for bone regeneration and recaps the current body of knowledge on nanomaterials with potential for osteoporosis treatment and bone regeneration. Specifically, we highlight new developments that are shaping this emerging field and evaluate applications of recently developed nanomaterials for osteoporosis treatment. Finally, we will identify promising new research directions in nanotechnology for bone regeneration. PMID:27048473

    Background Various osteoporosis guidelines are available for practice. Aim To understand the current clinical practice scenario from the perspective of Indian orthopaedicians, especially about the epidemiology, clinical manifestations, approach to diagnosis and management and patient compliance patterns to long term treatment. Materials and Methods A pre-validated structured questionnaire containing questions (mostly objective, some open-ended) catering to various objectives of the study was circulated amongst orthopaedic surgeons across India by means of post/courier, after giving a brief overview of the study telephonically. Data was extracted from the completed questionnaires, and analysed using Microsoft Excel software. Results The questionnaire was filled by a total of 84 orthopaedicians throughout India. The prevalence of osteoporosis in India according to the orthopaedic surgeons was 38.4% and there was a female preponderance. Most of the respondents felt out of every 100 osteoporosis patients in India, less than 20 patients are actually diagnosed and treated for osteoporosis. The most common initial presenting feature of established osteoporosis cases was general symptoms. Most respondents preferred Dual-energy X-ray absorptiometry (DEXA) as the initial investigation for the diagnosis of osteoporosis in a patient presenting with typical features. While most respondents preferred once-a-month oral over intravenous (IV) bisphosphonates, they agreed that IV administration had advantages such as lower gastrointestinal side effects and improved compliance. The average duration of therapy of oral bisphosphonates was the longest (27.04 months) among the other anti- osteoporosis therapies that they used. On an average, the patient compliance rate in osteoporosis management was around 64%. IV Zoledronic acid (ZA) and intranasal calcitonin were infrequently used than other anti- osteoporosis therapies.

    Summary Osteoporosis is a multifactorial skeletal disorder characterized by the decrease of bone mass and the alteration of bone microarchitecture that leads to the increase of fracture risks. Traditionally, osteoporosis has been classified into primary and secondary osteoporosis. Primary osteoporosis refers to osteoporotic conditions which are not related to other chronic illnesses and is usually associated with aging and decreased gonadal function, such as decreased level of estrogen, whereas secondary osteoporosis is the type of osteoporosis caused by other health problems. Disuse is one of the many reasons inducing bone loss and resulting in secondary osteoporosis. The disuse osteoporosis appeared for the first time in the literature in 1974 when Minaire reported some histomorphometric analysis of iliac crest bone biopsies performed after a spinal cord injury. The most common skeleton sites in which disuse osteoporosis can be observed are knees and ankles. There are three clinical situation in which this disease can be observed: neurological or muscular disease that causes a pathological and prolonged immobilization. The most frequent is caused by a spinal cord injury, long term bed rest or space flight that causes the immobilization linked to changes in mechanical environment and experimental immobilizations in healthy subjects. Physical exercise is essential for increasing or maintaining bone mass and strength. In our study we wondered if the disuse of the upper limbs of a certain entity, lasting for a long time, can cause a decrease in BMD quantifiable with a densitometric evaluation of the distal radius and with an evaluation of the humeral cortical index such as to define a real osteoporosis from disuse. We analyzed 30 female patients without secondary osteoporosis older than 60 years: everyone underwent to vit D evaluation, densitometric exams of spine, hip and distal radius, Constant score and femoral and humeral cortical index evaluation. We observed

    In 1985 150 children aged 0-18 were reported to the Danish National Register for Visually Impaired Children. Cross tabulation of the ophthalmological diagnoses by site and type of affection was performed with respect to year of birth, aetiology, visual acuity and birth weight. Finally the relations between aetiology and the presence of additional handicaps are demonstrated. The 'incidence of notification' (IN) was calculated for each birth year as the number of notified children per 100,000 within each birth year group showing variations between 46 in the 1984 birth year group and 3 in the 1970 birth year group with a mean value of 14. The figures stress the impact of congenital and neonatal visual impairment. The significance of IN is discussed with respect to other concepts of incidence. It is concluded that the presented epidemiological method is useful as a tool of analysis in the planning of preventional strategies. From the tables the following main features may be highlighted: Nearly 90% of the blinding causes anatomically are located in the posterior segment of the eye, the optic pathways or in the brain. Isolated visual handicap was notified in 34% of the children, while another 48% presented central nervous system involvement. From an aetiological point of view it is noteworthy that no specific aetiology could be encircled in 38% of the material. In conclusion, it is proposed that future lines of ophthalmological work in the prevention of visual handicap in childhood should concentrate on a higher degree of specificity in diagnostic procedures and an intensified search for specific aetiologies in every single child with visual impairment.

    Background Osteoporosis treatment following hip fracture is well known to not enough. We previously performed intervention study for orthopaedic surgeon's education and reported twofold increase in osteoporosis detection and treatment rate observed between 2005 and 2007. This follow-up observational study was conducted to find out the rate in which a diagnostic workup and treatment for osteoporosis were done in patients with hip fracture. Methods Medical records and radiographs in patients who were older than 50 years and diagnosed as having femoral neck or intertrochanteric fractures at 8 hospitals in Jeju island, South Korea from 2008 to 2011 were reviewed. The numbers of patients who were studied with bone densitometry and who were treated for osteoporosis after the diagnosis of hip fracture were analyzed. Results Nine hundred forty five hip fractures (201 in 2008, 257 in 2009, 265 in 2010, and 304 in 2011) occurred in 191 men and 754 women during the study periods. The mean age of the patients was 79.7 years. The mean rate of osteoporosis detection using dual energy X-ray absorptiometry was 36.4% (344/945 hips) (ranged from 24.2% in 2009 to 40.5% in 2011). The mean initiation rate of osteoporosis treatment was 23.1% (218/945 hips) (ranged from 20% in 2009 to 29% in 2008). Conclusions Detection and treatment rate of osteoporosis following hip fracture during follow-up periods was still not enough. Additional intervention studies are required to further improvement of osteoporosis treatment rates after hip fracture. PMID:25489575

    Abstract To investigate osteoporosis risk in patients with peptic ulcer disease (PUD) using a nationwide population-based dataset. This Taiwan National Health Insurance Research Database (NHIRD) analysis included 27,132 patients aged 18 years and older who had been diagnosed with PUD (International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM] codes 531–534) during 1996 to 2010. The control group consisted of 27,132 randomly selected (age- and gender)-matched patients without PUD. The association between PUD and the risk of developing osteoporosis was estimated using a Cox proportional hazard regression model. During the follow-up period, osteoporosis was diagnosed in 2538 (9.35 %) patients in the PUD group and in 2259 (8.33 %) participants in the non-PUD group. After adjusting for covariates, osteoporosis risk was 1.85 times greater in the PUD group compared to the non-PUD group (13.99 vs 5.80 per 1000 person-years, respectively). Osteoporosis developed 1 year after PUD diagnosis. The 1-year follow-up period exhibited the highest significance between the 2 groups (hazard ratio [HR] = 63.44, 95% confidence interval [CI] = 28.19–142.74, P < 0.001). Osteoporosis risk was significantly higher in PUD patients with proton-pump-inhibitors (PPIs) use (HR = 1.17, 95% CI = 1.03–1.34) compared to PUD patients without PPIs use. This study revealed a significant association between PUD and subsequent risk of osteoporosis. Therefore, PUD patients, especially those treated with PPIs, should be evaluated for subsequent risk of osteoporosis to minimize the occurrence of adverse events. PMID:27100415

    Background Osteoporosis-related fractures are a significant public health concern. Interventions that increase detection and treatment of osteoporosis are underutilized. This pragmatic randomised study was done to evaluate the impact of a multifaceted community-based care program aimed at optimizing evidence-based management in patients at risk for osteoporosis and fractures. Methods This was a 12-month randomized trial performed in Ontario, Canada. Eligible patients were community-dwelling, aged ≥55 years, and identified to be at risk for osteoporosis-related fractures. Two hundred and one patients were allocated to the intervention group or to usual care. Components of the intervention were directed towards primary care physicians and patients and included facilitated bone mineral density testing, patient education and patient-specific recommendations for osteoporosis treatment. The primary outcome was the implementation of appropriate osteoporosis management. Results 101 patients were allocated to intervention and 100 to control. Mean age of participants was 71.9 ± 7.2 years and 94% were women. Pharmacological treatment (alendronate, risedronate, or raloxifene) for osteoporosis was increased by 29% compared to usual care (56% [29/52] vs. 27% [16/60]; relative risk [RR] 2.09, 95% confidence interval [CI] 1.29 to 3.40). More individuals in the intervention group were taking calcium (54% [54/101] vs. 20% [20/100]; RR 2.67, 95% CI 1.74 to 4.12) and vitamin D (33% [33/101] vs. 20% [20/100]; RR 1.63, 95% CI 1.01 to 2.65). Conclusions A multi-faceted community-based intervention improved management of osteoporosis in high risk patients compared with usual care.

    Reactive oxygen species (ROS) are a significant pathogenic factor of osteoporosis. Ginsenoside-Rb2 (Rb2), a 20(S)-protopanaxadiol glycoside extracted from ginseng, is a potent antioxidant that generates interest regarding the bone metabolism area. We tested the potential anti-osteoporosis effects of Rb2 and its underlying mechanism in this study. We produced an oxidative damage model induced by hydrogen peroxide (H2O2) in osteoblastic MC3T3-E1 cells to test the essential anti-osteoporosis effects of Rb2in vitro. The results indicated that treatment of 0.1 to 10μM Rb2 promoted the proliferation of MC3T3-E1 cells, improved alkaline phosphatase (ALP) expression, elevated calcium mineralization and mRNA expressions of Alp, Col1a1, osteocalcin (Ocn) and osteopontin (Opn) against oxidative damage induced by H2O2. Importantly, Rb2 reduced the expression levels of receptor activator of nuclear factor kappa-B ligand (RANKL) and IL-6 and inhibited the H2O2-induced production of ROS. The in vivo study indicated that the Rb2 administered for 12weeks partially decreased blood malondialdehyde (MDA) activity and elevated the activity of reduced glutathione (GSH) in ovariectomized (OVX) mice. Moreover, Rb2 improved the micro-architecture of trabecular bones and increased bone mineral density (BMD) of the 4th lumbar vertebrae (L4) and the distal femur. Altogether, these results demonstrated that the potential anti-osteoporosis effects of Rb2 were linked to a reduction of oxidative damage and bone-resorbing cytokines, which suggests that Rb2 might be effective in preventing and alleviating osteoporosis.

    Osteoporosis is a systemic metabolic bone disease characterized by a reduction in bone mass, bone quality, and microarchitectural deterioration. An imbalance in bone remodeling that is caused by more osteoclast-mediated bone resorption than osteoblast-mediated bone formation results in such pathologic bone disorder. Traditional Chinese medicines (TCM) have long been used to prevent and treat osteoporosis and have received extensive attentions and researches at home and abroad, because they have fewer adverse reactions and are more suitable for long-term use compared with chemically synthesized medicines. Here, we put the emphasis on osteoblasts, summarized the detailed research progress on the active compounds derived from TCM with potential anti-osteoporosis effects and their molecular mechanisms on promoting osteoblast-mediated bone formation. It could be concluded that TCM with kidney-tonifying, spleen-tonifying, and stasis-removing effects all have the potential effects on treating osteoporosis. The active ingredients derived from TCM that possess effects on promoting osteoblasts proliferation and differentiation include flavonoids, glycosides, coumarins, terpenoids (sesquiterpenoids, monoterpenoids, diterpenoids), phenolic acids, phenols and others (tetrameric stilbene, anthraquinones, diarylheptanoids). And it was confirmed that the bone formation effect induced by the above natural products was regulated by the expressions of bone specific matrix proteins (ALP, BSP, OCN, OPN, COL I), transcription factor (Runx2, Cbfa1, Osx), signal pathways (MAPK, BMP), local factors (ROS, NO), OPG/RANKL system of osteoblasts and estrogen-like biological activities. All the studies provided theoretical basis for clinical application, as well as new drug research and development on treating osteoporosis. PMID:26796578

Methods Data from the 2011 Japan National Health and Wellness Survey (NHWS; n = 30 000), an internet health survey fielded to a nationally representative sample of the Japanese population were used. Only women between the ages of 50-90 years were included in the analyses (n = 6950). Results Compared with matched controls (n = 404), patients with osteoporosis (n = 404) had lower MCS scores (48.94 vs 51.63), PCS scores (45.57 vs 49.12) (all p < 0.05). The presence of osteoporosis was associated with worse patient outcomes among those with hypertension, high cholesterol, and insomnia, among other conditions. Conclusions The results suggest a significant quality-of-life and economic burden for patients with osteoporosis in Japan. Moreover, in a complex co-morbid environment, the presence of osteoporosis contributes more to patient outcomes than other chronic conditions. PMID:26929988

    Osteoporosis is the common cause for a broken bone among senior citizens. Early diagnosis of osteoporosis requires routine examination which may be costly for patients. A potential low cost diagnosis is to identify a senior citizen at high risk of osteoporosis by pre-screening during routine dental examination. Therefore, osteoporosis analysis using dental radiographs severs as a key step in routine dental examination. The aim of this study is to localize landmarks in dental radiographs which are helpful to assess the evidence of osteoporosis. We collect eight landmarks which are critical in osteoporosis analysis. Our goal is to localize these landmarks automatically for a given dental radiographic image. To address the challenges such as large variations of appearances in subjects, in this paper, we formulate the task into a multi-class classification problem. A hybrid feature pool is used to represent these landmarks. For the discriminative classification problem, we use a random forest to fuse the hybrid feature representation. In the experiments, we also evaluate the performances of individual feature component and the hybrid fused feature. Our proposed method achieves average detection error of 2:9mm.

    Treatment of osteoporosis remains a therapeutic challenge. The effect of Apium Nodiflorum extract on development of experimental osteoporosis, pain thresholds and carrageenan-induced inflammation has been studied in ovariectomized osteoporotic Wistar rats. After osteoporosis verification rats were randomized and received vehicle only, HPLC-standardized Apium extract (equal to 2.4 mg/kg Quercetin) or Genistein (2.5 mg/kg) for 8 weeks. To verify the effect of Apium on the development of osteoporosis, bone mineral density (BMD) and bone mineral content (BMC), bone histology and plasma levels of IL-6 and RANKL were measured 6 months after ovariectomy and 8 weeks after treatment with Apium extract or Genistein as comparator. Inflammatory hyperalgesia was induced by intraplantar injection of 1% Carrageenan. Apium extract and Genistein impeded the development of osteoporosis (significant differences were shown for BMC and BMD levels in drug vs. vehicle treated rats) and improved bone histology and histological score. Apium and Genistein decreased IL-6 level. Both treatments alleviated mechanical hyperalgesia, decreased exudative reaction and lowered inflammatory pain threshold. The results suggested that Apium extract could be an alternative therapy for post-menopausal osteoporosis. PMID:25543689

    Osteoporosis is a widespread disorder, which has a catastrophic impact on patients lives and overwhelming related to healthcare costs. Recently, we proposed a multispectral photoacoustic technique for early detection of osteoporosis. Such technique has great advantages over pure ultrasonic or optical methods as it allows the deduction of both bone functionality from the bone absorption spectrum and bone resistance to fracture from the characteristics of the ultrasound propagation. We demonstrated the propagation of multiple acoustic modes in animal bones in-vitro. To further investigate the effects of multiple wavelength excitations and of induced osteoporosis on the PA signal a multispectral photoacoustic system is presented. The experimental investigation is based on measuring the interference of multiple acoustic modes. The performance of the system is evaluated and a simple two mode theoretical model is fitted to the measured phase signals. The results show that such PA technique is accurate and repeatable. Then a multiple wavelength excitation is tested. It is shown that the PA response due to different excitation wavelengths revels that absorption by the different bone constitutes has a profound effect on the mode generation. The PA response is measured in single wavelength before and after induced osteoporosis. Results show that induced osteoporosis alters the measured amplitude and phase in a consistent manner which allows the detection of the onset of osteoporosis. These results suggest that a complete characterization of the bone over a region of both acoustic and optical frequencies might be used as a powerful tool for in-vivo bone evaluation.

    Eating disorders (TCA per its abbreviation in Spanish) are common in young women, with an estimated prevalence of 4-5%. One of the physical complications of eating disorders, especially anorexia nervosa (AN) and eating disorder not otherwise specified (TANE) is bone mass loss, which affects both cortical and trabecular bone. The synergistic effect of malnutrition and estrogen deficiency produces significant bone mass loss, resulting from the uncoupling of bone turnover characterized by a decrease in osteoblastic bone formation and an increase in osteclastic bone resorption. The mechanisms implied in the pathogenesis of bone loss are the hypoestrogenism, hypercortisolism, serum leptin levels and insulin-like growth factor decrease. Severity of bone loss in anorexia nervosa varies depending on duration of illness, the minimal weight ever and sedentarism or strenuous exercise. Long term consequences occur, such as a fracture risk increase in patients who have suffered anorexia nervosa, compared with the general population. The first treatment line to recover bone mass is nutritional rehabilitation together with weight gain. Hormonal replacement therapy may be effective if combined with an anabolic method. Osteopenia and osteoporosis are terms adopted to define the deficiency of bone mass in adults. Authors have used these terms to define densitometric data in young subjects who have not reached their peak bone mass. We suggest the term "hypo-osteogenesia" to define the deficiency in the development of bone mass in adolescents or children. PMID:16259293

    In elderly women, loss in bone mass and micro-architectural changes are generally attributed to the onset of menopause. Men do not experience menopause, they do, however, experience age-related acceleration in bone loss and micro-architecture deterioration. The incidence of osteoporotic fractures in elderly men, just as in aged women, increases exponentially with age; the rise in men, however, is some 5–10 years later than in women. Up to 50% of male osteoporotics have no identifiable etiology; however elderly males have much higher likelihood of having an identifiable secondary cause than younger men. Therefore, clinical and laboratory evaluation of aged male osteoporotics must be thorough and should be aimed at identifying lifestyle or conditions contributing to bone loss and fragility. It is essential to identify and treat secondary causes and ensure adequate vitamin D and calcium intake before embarking upon treatment with pharmacological agents. The evidence from a limited number of trials suggests that bisphosphonates, especially alendronate and risedronate, are effective in improving BMD, and seem to be the treatments of choice in aged men with osteoporosis. In cases where bisphosphonates are contra-indicated or ineffective, teriparatide or alternatives such as strontium should be considered. PMID:18225452

    Osteoporosis therapy has been handicapped by lack of means to quantitate the process. Dual photon absorptiometry (DPA) offers accurate (4%) and precise (2%) estimation of lumbar spine mineral. The authors followed 42 osteoporotics to determine response to therapy. There were 17 patients with normal menopause (NM), 4 with surgical menopause (SM), 3 with premature menopause (PM), and 18 with idiopathic osteoporoses (10). Intervals between DPA spine mineral estimation were 16.5 +- 5.2 mo. for NM, 14.3 +- 8.4 mo. for SM, 14.0 +- 7.5 mo. for PM and 16.7 +- 5.8 mo. for 10. Observed average percent change of spine mineral under therapy for those intervals was 5.2 +- 7.9% for NM, +7.3 +- 1.7% for SM, -2.4 +- 6.3% for PM and +1.8 +- 12.3% for 10. Therapy invariably was with Ca, low dose Premarin in NM and PM, often with phosphates in IO, sometimes with thiazides, often with Vitamin D and with occasional other modalities, including NaF. The authors find DPA is a cost-effective way to measure osteopenia in the osteoporeses, document response to therapy, identify need for therapy change when there is continued bone loss under therapy, and to encourage the patient's compliance with long-term, complex therapies.

    Quantitative bone scintigraphy was performed on 23 white females with post-menopausal osteoporosis and vertebral compression fractures. These patients were then entered into a randomized, double-blind clinical trial or sodium fluoride therapy (NaF=14, placebo=9) which included repeat bone scintigraphy every six months. Scintigraphic images were acquired for 500K counts per image over the total body with computer acquisition over the posterior thoracic and lumbar spine. Images were obtained on a wide field-of-view gamma camera two hours after injecting 15 mCi of Tc-99m MDP. Data analysis showed a significant reduction in the activity ratio of abnormal vertebral body to normal vertebral body in those patients treated with sodium fluoride (paired t-test p=0.0095). No significant change was observed in the control group of (p=0.142). These results suggest that sodium fluoride therapy promotes more rapid healing of osteoporotic vertebral fractures. They also demonstrate the utility of serial quantitative bone scintigraphy in assessing osteoporotic patients with vertebral compression fractures.

  18. Affective Disorders, Bone Metabolism, and Osteoporosis

    The nature of the relationship between affective disorders, bone mineral density (BMD), and bone metabolism is unresolved, although there is growing evidence that many medications used to treat affective disorders are associated with low BMD or alterations in neuroendocrine systems that influence bone turnover. The objective of this review is to describe the current evidence regarding the association of unipolar and bipolar depression with BMD and indicators of bone metabolism, and to explore potential mediating and confounding influences of those relationships. The majority of studies of unipolar depression and BMD indicate that depressive symptoms are associated with low BMD. In contrast, evidence regarding the relationship between bipolar depression and BMD is inconsistent. There is limited but suggestive evidence to support an association between affective disorders and some markers of bone turnover. Many medications used to treat affective disorders have effects on physiologic systems that influence bone metabolism, and these conditions are also associated with a range of health behaviors that can influence osteoporosis risk. Future research should focus on disentangling the pathways linking psychotropic medications and their clinical indications with BMD and fracture risk. PMID:23874147

    Last researches on Osteoporosis disease show's that the correlation between BMD information that come from DXA, and the fractual risk are not enough correlated. For this reason, new techniques that could be more sensitive and give different information's on the bone are being looking for. The key for success is to find a technique that could be detected changes in the micro-structure inside the trabecular bone, and supply more information on this structure. We have shown that pulse ultrasound light tomography could work in well reflection configuration and on living tissue to measure locally the "reduce scattering coefficient" inside the body. This technique could work deep inside the body (few cm) and could supply very good resolution. In the beginning on this research we show clinical results that justified planning more accurate and larger clinical study. The system suffers from mechanical and body interface problems that only very skill and professional physician could get a good results. This system also suffers from low signal to noise ratio, and irrevocable data on the same people. In this lecture we will present an upgrade and improved system. The mechanical and body interface changes will present and discusses. A good repeated data will be presented on phantoms and on peoples. Finally, large clinical data that operated in clinical technician on 60 Ultra distal bone peoples will present in compare to DXA data that was measure on the same peoples on the same place.
