Abstract
Osteoporosis, a metabolic bone disease characterized by low bone mineral density and deterioration of bone microarchitecture, has led to a high risk of fatal osteoporotic fractures worldwide. Accumulating evidence has revealed that sexual dimorphism is a notable feature of osteoporosis, with sex-specific differences in epidemiology and pathogenesis. Specifically, females are more susceptible than males to osteoporosis, while males are more prone to disability or death from the disease. To date, sex chromosome abnormalities and steroid hormones have been proven to contribute greatly to sexual dimorphism in osteoporosis by regulating the functions of bone cells. Understanding the sex-specific differences in osteoporosis and its related complications is essential for improving treatment strategies tailored to women and men. This literature review focuses on the mechanisms underlying sexual dimorphism in osteoporosis, mainly in a population of aging patients, chronic glucocorticoid administration, and diabetes. Moreover, we highlight the implications of sexual dimorphism for developing therapeutics and preventive strategies and screening approaches tailored to women and men. Additionally, the challenges in translating bench research to bedside treatments and future directions to overcome these obstacles will be discussed.

Abstract
It is estimated that 2% to 3% of the population are currently prescribed systemic or topical glucocorticoid treatment. The potent anti-inflammatory action of glucocorticoids to deliver therapeutic benefit is not in doubt. However, the side effects associated with their use, including central weight gain, hypertension, insulin resistance, type 2 diabetes (T2D), and osteoporosis, often collectively termed iatrogenic Cushing's syndrome, are associated with a significant health and economic burden. The precise cellular mechanisms underpinning the differential action of glucocorticoids to drive the desirable and undesirable effects are still not completely understood. Faced with the unmet clinical need to limit glucocorticoid-induced adverse effects alongside ensuring the preservation of anti-inflammatory actions, several strategies have been pursued. The coprescription of existing licensed drugs to treat incident adverse effects can be effective, but data examining the prevention of adverse effects are limited. Novel selective glucocorticoid receptor agonists and selective glucocorticoid receptor modulators have been designed that aim to specifically and selectively activate anti-inflammatory responses based upon their interaction with the glucocorticoid receptor. Several of these compounds are currently in clinical trials to evaluate their efficacy. More recently, strategies exploiting tissue-specific glucocorticoid metabolism through the isoforms of 11β-hydroxysteroid dehydrogenase has shown early potential, although data from clinical trials are limited. The aim of any treatment is to maximize benefit while minimizing risk, and within this review we define the adverse effect profile associated with glucocorticoid use and evaluate current and developing strategies that aim to limit side effects but preserve desirable therapeutic efficacy.

Abstract
Osteoporosis management has become more relevant as the life expectancy increases. In Ecuador, approximately 19% of adults over 65 years of age have been diagnosed with osteoporosis. There is no national consensus for the management and prevention of the disease being this proposal the first Ecuadorian consensus. INTRODUCTION In Ecuador, it is estimated that around 19% of adults over 65 years of age have osteoporosis. Due to the increase in life expectancy in the world population, the evaluation and management of osteoporosis has become more relevant. Currently, there is no national consensus for the management and prevention of the disease. The Ecuadorian Society of Rheumatology presented the project for the elaboration of the first Ecuadorian consensus for the management and prevention of osteoporosis. METHODS A panel of experts in multiple areas and extensive experience was invited to participate. The consensus was carried out using the Delphi method. Six working dimensions were created: definition and epidemiology of osteoporosis, fracture risk prediction tools, non-pharmacological treatment, pharmacological treatment, calcium and vitamin D, and glucocorticoid-induced osteoporosis. RESULTS The first round was held in December 2021, followed by the second round in February 2022 and the third round in March 2022. The data was shared with the specialists at the end of each round. After three rounds of work, a consensus was reached for the management and prevention of osteoporosis. CONCLUSION This is the first Ecuadorian consensus for the management and treatment of postmenopausal osteoporosis.

[PMID: 37171596 PMCID: PMC10175903 DOI: 10.1007/s00277-023-05266-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2023] [Accepted: 05/06/2023] [Indexed: 05/13/2023]
Abstract
Prednisolone, used as a standard initial treatment for immune thrombocytopenia (ITP), is an important risk factor for osteoporosis. Recently, we found that prescription of bisphosphonate during initial loading of prednisolone may prevent reduction in bone mineral density and development of glucocorticoid-induced osteoporosis (GIO) in older patients with ITP receiving prolonged steroid therapy. In this review, I describe the treatment options for older patients with ITP, and present the best practices for screening, evaluating, and diagnosing ITP. I also summarize the literature from 2017 to 2022 on the treatment options for ITP, including discussions on the contraindications and side effects, with an emphasis on GIO, and the relative merits of bisphosphonates as a co-treatment for prevention of GIO. Finally, I present a perspective and an expert recommendation on how older patients with ITP would best be served in the future.

Abstract
INTRODUCTION AND AIM T-score bone mineral density (BMD) thresholds may influence guidance for treatment in patients under glucocorticoid (GC) therapy. Different BMD thresholds have been described but there is no international consensus. The aim of this study was to find a threshold to help in treatment decision-making in the population under GC therapy. METHODS A working group representing three scientific societies from Argentina was convened. The first team was formed by specialists with expertise in glucocorticoid-induced osteoporosis (GIO) who voted according to summary of evidence. The second team was constituted by a methodology group who coordinated and supervised each stage. We conducted two systematic reviews to synthesize the evidence. The first included trials of drugs used in GIO to analyze the BMD cut-off used as inclusion criteria. In the second, we analyzed the evidence regarding the densitometric thresholds to discriminate between fractured and non-fractured patients under GC treatment. RESULTS In the first review, 31 articles were included for qualitative synthesis and more than 90% of the trials included patients regardless of their densitometric T-score or range of osteopenia. In the second review, 4 articles were included and more than 80% of the T-scores were in the range -1.6 to -2.0. The summary of findings was analyzed and put to a vote. CONCLUSIONS With more than 80% agreement of the voting expert panel, a T-score≤-1.7 was considered the most appropriate for treatment in postmenopausal women and men over 50 years of age under GC therapy. This study could help in treatment decision-making in patients under GC therapy without fractures but other fracture risk factors should certainly be considered.

Abstract
Animal models are fundamental to advance our knowledge of the underlying pathophysiology of bone loss and to study pharmaceutical countermeasures against it. The animal model of post-menopausal osteoporosis from ovariectomy is the most widely used preclinical approach to study skeletal deterioration. However, several other animal models exist, each with unique characteristics such as bone loss from disuse, lactation, glucocorticoid excess, or exposure to hypobaric hypoxia. The present review aimed to provide a comprehensive overview of these animal models to emphasize the importance and significance of investigating bone loss and pharmaceutical countermeasures from perspectives other than post-menopausal osteoporosis only. Hence, the pathophysiology and underlying cellular mechanisms involved in the various types of bone loss are different, and this might influence which prevention and treatment strategies are the most effective. In addition, the review sought to map the current landscape of pharmaceutical countermeasures against osteoporosis with an emphasis on how drug development has changed from being driven by clinical observations and enhancement or repurposing of existing drugs to today's use of targeted anti-bodies that are the result of advanced insights into the underlying molecular mechanisms of bone formation and resorption. Moreover, new treatment combinations or repurposing opportunities of already approved drugs with a focus on dabigatran, parathyroid hormone and abaloparatide, growth hormone, inhibitors of the activin signaling pathway, acetazolamide, zoledronate, and romosozumab are discussed. Despite the considerable progress in drug development, there is still a clear need to improve treatment strategies and develop new pharmaceuticals against various types of osteoporosis. The review also highlights that new treatment indications should be explored using multiple animal models of bone loss in order to ensure a broad representation of different types of skeletal deterioration instead of mainly focusing on primary osteoporosis from post-menopausal estrogen deficiency.

Abstract
BACKGROUND Cushing's syndrome is known as an important cause of secondary osteoporosis, characterized by reduction of bone mineral density and potential occurrence of fragility fractures before diagnosis in young population. Therefore, for young patients with fragility fractures, especially in young women, more attention should be paid on glucocorticoid excess caused by Cushing's syndrome, due to relatively higher rate of misdiagnosis, distinct pathological characteristics and different treatment strategies compared with violent fractures and primary osteoporosis related fractures. CASE PRESENTATION We presented an unusual case of a 26-year-old woman with multiple vertebral compression fractures and pelvis fractures, subsequently diagnosed as Cushing's syndrome. On admission, the radiographic results showed fresh second lumbar vertebra fracture, and old fourth lumbar vertebra and pelvic fractures. The dual energy X-ray absorptiometry of lumbar spine revealed marked osteoporosis, and her plasm cortisol was extremely high. Then, Cushing's syndrome, caused by left adrenal adenoma, was diagnosed by further endocrinological and radiographic examinations. After receiving left adrenalectomy, her plasma ACTH and cortisol values returned to normal level. In term of OVCF, we adopted conservative treatments, including pain management, brace treatment, and anti-osteoporosis measures. Three months after discharge, the patient's low back pain was in complete remission without new onset of pain, and returned to normal life and work. Furthermore, we reviewed the literatures on advancements in the treatment of OVCF caused by Cushing's syndrome, and based on our experiences, proposed some additional perspectives to guide treatment. CONCLUSION In term of OVCF secondary to Cushing's syndrome without neurological damage, we prefer systematic conservative treatments, including pain management, brace treatment, and anti-osteoporosis measures, to surgical treatment. Among them, anti-osteoporosis treatment has the highest priority because of the reversibility of osteoporosis caused by Cushing's syndrome.

Evidence based Latin American Guidelines of clinical practice on prevention, diagnosis, management and treatment of glucocorticoid induced osteoporosis. A 2022 update : This manuscript has been produced under the auspices of the Committee of National Societies (CNS) and the Committee of Scientific Advisors (CSA) of the International Osteoporosis Foundation (IOF). Aging Clin Exp Res 2022; 34:2591-2602. [PMID: 36348222 DOI: 10.1007/s40520-022-02261-2] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Accepted: 09/16/2022] [Indexed: 11/11/2022]
Abstract
Guidelines and recommendations developed and endorsed by the International Osteoporosis Foundation (IOF) are intended to provide guidance for particular pattern of practice for physicians who usually prescribe glucocorticoid (GC) therapy, and not to dictate the care of a particular patient. Adherence to the recommendations within this guideline is voluntary and the ultimate determination regarding their application should be made by the physician in light of each patient's circumstances. Guidelines and recommendations are intended to promote a desirable outcome but cannot guarantee any specific outcome. This guideline and its recommendations are not intended to dictate payment, reimbursement or insurance decisions. Guidelines and recommendations are subjected to periodic revisions as a consequence of the evolution of medicine, technology and clinical practice. A panel of Latin American (LATAM) experts specialized in osteoporosis with recognized clinical experience in managing patients with glucocorticoid-induced osteoporosis (GIO) met to produce evidence-based LATAM recommendations for the diagnosis and management of GIO. These guidelines are particularly intended to general practitioners and primary care physicians who prescribe GC treatments in LATAM to guide their daily clinical practice in terms of evaluation, prevention and treatment of GIO. These recommendations were based on systematic literature review using MEDLINE, EMBASE, SCOPUS and COCHRANE Library database during the period from 2012 to 2021. Randomized clinical trials (RCT), systematic reviews of RCT, controlled observational studies, guidelines and consensus were considered. Based on the review and expert opinion the panel members voted recommendations during two successive rounds of voting by panel members. Agreements for each statement were considered if a concordance of at least 70% was achieved following Delphi methodology. Grading of recommendations was made according to the Oxford Centre for the Evidence-based Medicine (EBM) criteria. Among five GIO guidelines and consensus initially identified, two of them (American College of Rheumatology 2017 and the Brazilian Guidelines 2021) were selected for comparison considering the latter as the most current guides in the LATAM region. Based on this methodology fifty statements were issued. All of them but four (1.20, 1.21, 1.23 and 4.2) attained agreement.

Abstract
Glucocorticoid excess suppresses osteocyte remodeling of surrounding bone minerals, causes apoptosis of osteoblasts and osteocytes, and disrupts bone remodeling, eventually, leading to glucocorticoid-induced osteoporosis and bone fragility. Preventing apoptosis and preserving osteocyte morphology could be an effective means of preventing bone loss during glucocorticoid treatment. We hypothesized that osteocrin, which preserves osteocyte viability and morphology in Sp7-deficient mice, could prevent osteocyte death and dysfunction in a glucocorticoid excess model. We used adeno-associated virus (AAV8) to induce osteocrin overexpression in mice one week before implantation with prednisolone or placebo pellets. After 28 days, prednisolone caused the expected reduction in cortical bone thickness and osteocyte canalicular length in control AAV8-treated mice, and these effects were blunted in mice receiving AAV8-osteocrin. Glucocorticoid-induced changes in cortical porosity, trabecular bone mass, and gene expression were not prevented by osteocrin. These findings support a modest therapeutic potential for AAV8-osteocrin in preserving osteocyte morphology during disease.

Abstract
The following substances are approved for the treatment of glucocorticoid-induced osteoporosis: the oral bisphosphonates alendronate and risedronate, the intravenous bisphosphonate zoledronate, the RANKL antibody denosumab as antiresorptive substances and teriparatide as osteoanabolic substance. In comparison to placebo a reduction of vertebral fractures is proven for all mentioned substances. Thereby, teriparatide is more effective than alendronate and risedronate with respect to the reduction of vertebral fractures. The severity of osteoporosis, especially the presence of osteoporotic fractures, the approach of treatment (preventive or curative) and contraindications are factors that are important for the differentiated application of the mentioned substances. Furthermore, it must be noted that the effect of osteoanabolic treatment must be stabilized by a subsequent antiresorptive treatment and that after termination of antiresorptive treatment with denosumab a temporary bisphosphonate treatment is required to prevent a rebound phenomenon.

Abstract
BACKGROUND Glucocorticoids are of substantial therapeutic importance in the treatment of inflammatory diseases, but are also associated with bone mineral density loss, osteoporosis, and fractures, especially with long-term use. OBJECTIVE To develop recommendations for the management of glucocorticoid-induced osteoporosis (GIOP) in adult patients on long-term glucocorticoid (GC) treatment. METHODS A systematic literature search (SLR) was conducted to synthesize the evidence for GIOP prevention and treatment options. Recommendations were developed based on SLR/level of evidence and by previously defined questions and in a structured group consensus process. RESULTS Recommendations include supplementation with calcium and vitamin D under long-term GC therapy in adults. If specific osteologic treatment is indicated, we recommend bisphosphonates or denosumab as first-line treatment. If fracture risk is high, we recommend teriparatide as primary specific osteologic treatment. Denosumab should be used in cases of severe renal insufficiency, and specific osteologic treatment should not be given in pregnancy. For patients who have not reached the treatment goal, a switch to another class of specific osteologic drugs should be performed. We recommend re-evaluation after a treatment duration of 3-5 years or after termination of long-term GC treatment. CONCLUSION This work aims to provide evidence-based and consensus-based recommendations for the best possible management of GIOP in Germany and to support treatment decisions.

[PMID: 34733465 PMCID: PMC8560280 DOI: 10.1155/2021/5515653] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/12/2021] [Accepted: 10/16/2021] [Indexed: 11/18/2022] Open
Abstract
We aimed to evaluate the compliance of physicians with the 2014 guidelines of the Japanese Society for Bone and Mineral Research, for the prevention and treatment of glucocorticoid (GC) induced osteoporosis (GIO) and to investigate the risk of fracture and other associated risk factors in bisphosphonate-treated patients. We evaluated 90 female patients with nonrheumatoid arthritis autoimmune diseases who received long-term GC treatment (≥12 months). Clinical characteristics, including age, GC dose, history of fragility fractures, osteoporosis treatments, as well as lumbar (L2-L4) and femoral neck bone mineral density, were collected from the patients' medical charts. New vertebral fractures during the study period were evaluated using thoracic and lumbar spine radiographs by quantitative measurements. The GIO score was calculated for each patient according to 2014 Japanese guidelines. Of the 90 patients evaluated, 60 were indicated for osteoporosis treatment, based on the 2014 guidelines of Japan. We observed a high compliance rate, with 93% of patients receiving osteoporosis treatment and 50% receiving bisphosphonates. In total, eight patients developed new vertebral fractures during the study, six of whom received bisphosphonates. In bisphosphonate-treated patients, fracture risk was associated with GC treatment and a lack of active vitamin D3 supplementation. The compliance rate with the updated Japanese 2014 guidelines at our institution was very high. Large randomized controlled trials are needed to confirm our findings that suggest that active vitamin D3 should be used in combination with bisphosphonates for the treatment of GIO to reduce fracture risk.

Abstract
BACKGROUND Glucocorticoids are of substantial therapeutic importance in the treatment of inflammatory diseases, but are also associated with bone mineral density loss, osteoporosis, and fractures, especially with long-term use. OBJECTIVE To develop recommendations for the management of glucocorticoid-induced osteoporosis (GIOP) in adult patients on long-term glucocorticoid (GC) treatment. METHODS A systematic literature search (SLR) was conducted to synthesize the evidence for GIOP prevention and treatment options. Recommendations were developed based on SLR/level of evidence and by previously defined questions and in a structured group consensus process. RESULTS Recommendations include supplementation with calcium and vitamin D under long-term GC therapy in adults. If specific osteologic treatment is indicated, we recommend bisphosphonates or denosumab as first-line treatment. If fracture risk is high, we recommend teriparatide as primary specific osteologic treatment. Denosumab should be used in cases of severe renal insufficiency, and specific osteologic treatment should not be given in pregnancy. For patients who have not reached the treatment goal, a switch to another class of specific osteologic drugs should be performed. We recommend re-evaluation after a treatment duration of 3-5 years or after termination of long-term GC treatment. CONCLUSION This work aims to provide evidence-based and consensus-based recommendations for the best possible management of GIOP in Germany and to support treatment decisions.

Short-term glucocorticoid excess blunts abaloparatide-induced increase in femoral bone mass and strength in mice. Sci Rep 2021; 11:12258. [PMID: 34112892 PMCID: PMC8192916 DOI: 10.1038/s41598-021-91729-8] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2021] [Accepted: 05/31/2021] [Indexed: 12/21/2022] Open
Abstract
Glucocorticoids (GCs), such as prednisolone, are widely used to treat inflammatory diseases. Continuously long-term or high dose treatment with GCs is one of the most common causes of secondary osteoporosis and is associated with sarcopenia and increased risk of debilitating osteoporotic fragility fractures. Abaloparatide (ABL) is a potent parathyroid hormone-related peptide analog, which can increase bone mineral density (aBMD), improve trabecular microarchitecture, and increase bone strength. The present study aimed to investigate whether GC excess blunts the osteoanabolic effect of ABL. Sixty 12–13-week-old female RjOrl:SWISS mice were allocated to the following groups: Baseline, Control, ABL, GC, and GC + ABL. ABL was administered as subcutaneous injections (100 μg/kg), while GC was delivered by subcutaneous implantation of a 60-days slow-release prednisolone-pellet (10 mg). The study lasted four weeks. GC induced a substantial reduction in muscle mass, trabecular mineral apposition rate (MAR) and bone formation rate (BFR/BS), and endocortical MAR compared with Control, but did not alter the trabecular microarchitecture or bone strength. In mice not receiving GC, ABL increased aBMD, bone mineral content (BMC), cortical and trabecular microarchitecture, mineralizing surface (MS/BS), MAR, BFR/BS, and bone strength compared with Control. However, when administered concomitantly with GC, the osteoanabolic effect of ABL on BMC, cortical morphology, and cortical bone strength was blunted. In conclusion, at cortical bone sites, the osteoanabolic effect of ABL is generally blunted by short-term GC excess.

Abstract
Osteoporosis is less common in men than women; however, the mortality rate associated with major fragility fractures is higher in men. The diagnosis of osteoporosis is established by measurement of bone mineral density or by the presence of a fragility fracture, especially spine or hip fracture. However, many men at high risk of fracture will not meet the T-score criteria for osteoporosis, so fracture risk calculation, with a tool such as FRAX, should be performed. Bone-active agents should be prescribed for men at high risk of fracture to decrease fracture risk, and therapy must be individualized.

Abstract
Glucocorticoid-induced osteoporosis is the most common cause of secondary osteoporosis; nonetheless, it remains an undertreated condition. Transplantation-induced osteoporosis encompasses a broad range of unique pathogenetic features with distinct characteristics dependent on the transplanted organ. Understanding the pathogenesis of bone loss is key to recommending osteoporosis therapy in these patients. This review summarizes recent advances and addresses current issues in these fields.

Abstract
INTRODUCTION Bisphosphonates are the standard treatment for glucocorticoid-induced osteoporosis (GIOP) with teriparatide being another option. While daily teriparatide has been shown to be effective in increasing bone mineral density (BMD), the efficacy of once-weekly teriparatide (56.5 µg) has not yet been evaluated. The TOWER-GO study, a 72-week, multicenter, open-label, randomized controlled trial, was conducted in patients with GIOP to compare the effects of once-weekly teriparatide and once-weekly alendronate 35 mg on BMD. MATERIALS AND METHODS Patients (N = 180) with GIOP for whom drug treatment was indicated according to the 2004 guidelines in Japan were randomized to receive once-weekly teriparatide (n = 89) or once-weekly alendronate (n = 91). The primary endpoint was the non-inferiority of percentage change in lumbar spine BMD at final follow-up. The secondary endpoints were the percentage change in BMD from baseline, incidence of bone fractures, and changes in bone turnover markers. RESULTS While the non-inferiority of teriparatide to alendronate was not confirmed, BMD increased significantly from baseline with teriparatide and alendronate by 5.09% and 4.04%, respectively (both p < 0.05), at 72 weeks. The incidence of vertebral and non-vertebral fractures was similar in both groups. Bone formation markers increased in the teriparatide group and decreased in the alendronate group. CONCLUSIONS The non-inferiority of once-weekly teriparatide versus once-weekly alendronate in BMD change at 72 weeks was not shown, but the increase in bone formation markers over time and the increase of BMD in GIOP patients treated with once-weekly teriparatide were confirmed.

Abstract
UNLABELLED The Brazilian guidelines for prevention and treatment of glucocorticoid-induced osteoporosis were updated and important topics were included such as assessment of risk fracture using FRAX Brazil, use of denosumab, and also recommendations for the use of glucocorticoid pulse therapy and inhaled glucocortiocoid. INTRODUCTION Glucocorticoids (GCs) are used in almost all medical specialties and the incidences of vertebral/nonvertebral fractures range from 30 to 50% in individuals treated with GCs for over 3 months. Thus, osteoporosis and frailty fractures should be prevented and treated in patients initiating treatment or already being treated with GCs. The Committee for Osteoporosis and Bone Metabolic Disorders of the Brazilian Society of Rheumatology (BSR) established in 2012 the Brazilian Guidelines for glucocorticoid-induced osteoporosis (GIO). Herein, we provide a comprehensive update of the original guidelines based on improved available scientific evidence and/or expert experience. METHODS From March to June 2020, the Osteoporosis Committee of the BRS had meetings to update the questions presented in the first consensus (2012). Thus, twenty-six questions considered essential for the preparation of the recommendations were selected. A systematic literature review based on real-life scenarios was undertaken to answer the proposed questions. The MEDLINE, EMBASE, and SCOPUS databases were searched using specific search keywords. RESULTS Based on the review and expert opinion, the recommendations were updated for each of the 26 questions. We included 48 new bibliographic references that became available after the date of the publication of the first version of the consensus. CONCLUSION We updated the Brazilian guidelines for the prevention/treatment of GIO. New topics were added in this update, such as the assessment of risk fracture using FRAX Brazil, the use of denosumab, and approaches for the treatment of children and adolescents. Furthermore, we included recommendations for the use of inhaled GCs and GC pulse therapy in clinical settings.

Abstract
Background Glucocorticoids are widely used in a variety of diseases, especially autoimmune diseases and inflammatory diseases, so the incidence of glucocorticoid-induced osteoporosis is high all over the world. Objectives The purpose of this paper is to use the method of network meta-analysis (NMA) to compare the efficacy of anti-osteoporosis drugs directly and indirectly, and to explore the advantages of various anti-osteoporosis drugs based on the current evidence. Methods We searched PubMed, Embase and Cochrane Library for randomized controlled trials (RCTs), of glucocorticoid-induced osteoporosis (GIOP) and compared the efficacy and safety of these drugs by NMA. The risk ratio (RR) and its 95% confidence interval (CI) are used as the influence index of discontinuous data, and the standardized mean difference (SMD) and its 95% CI are used as the influence index of continuous data. The statistical heterogeneity was evaluated by the calculated estimated variance (τ2), and the efficacy and safety of drugs were ranked by the surface under the cumulative ranking curve (SUCRA). The main outcome of this study was the incidence of vertebral fracture after taking several different types of drugs, and the secondary results were the incidence of non-vertebral fracture and adverse events, mean percentage change of lumbar spine (LS) and total hip (TH)bone mineral density (BMD) from baseline to at least 12 months. Results Among the different types of anti-GIOP, teriparatide (SUCRA 95.9%) has the lowest incidence of vertebral fracture; ibandronate (SUCRA 75.2%) has the lowest incidence of non-vertebral fracture; raloxifene (SUCRA 98.5%) has the best effect in increasing LS BMD; denosumab (SUCRA 99.7%) is the best in increasing TH BMD; calcitonin (SUCRA 92.4%) has the lowest incidence of serious adverse events. Conclusions Teriparatide and ibandronate are effective drugs to reduce the risk of vertebral and non-vertebral fractures in patients with GIOP. In addition, long-term use of raloxifene and denosumab can increase the BMD of LS and TH.

Abstract
BACKGROUND What affects the efficacy of alendronate for prevention of glucocorticoid-induced (GI) fractures remains unclear. We aimed to explore the factors affecting alendronate's efficacy, and further identify subgroup effects of alendronate in preventing GI fractures. METHODS We searched 3 databases. Random-effects meta-analysis was conducted to synthesize risk ratio (RR) and 95% confidence interval (CI) for each endpoint. Meta-regression analysis was used to explore sources of heterogeneity, and subgroup analysis was used to address heterogeneity and evaluate subgroup effects. We detected publication bias using funnel plots and Egger tests. RESULTS We included 13 papers from 12 unique studies involving 46431 participants. Glucocorticoid (GC) dosage (P = .053) and proportion of previous vertebral fracture (PVF) (P = .047) were probably 2 sources of heterogeneity in meta-analysis for vertebral fractures, while GC duration (P = .020) was probably 1 for nonvertebral fractures. Alendronate reduced vertebral fractures in the high dosage subgroup (RR 0.61, 95% CI 0.44-0.86), but didn't in the low dosage subgroup (RR 1.56, 95% CI 0.20-12.02). Alendronate reduced vertebral fractures (RR 0.53, 95% CI 0.40-0.68) in the subgroup of PVF proportion <5%, but didn't (RR 0.76, 95% CI 0.42-1.37) in the subgroup of this proportion ≥5%. Alendronate reduced nonvertebral and hip fractures, whether in primary or in secondary prevention subgroup. CONCLUSIONS The findings in our study support that alendronate is used for the primary and secondary prevention of GI fractures, but do not support that alendronate is recommended as a first-line agent for patients receiving a low dose of GCs or patients with PVF.

Abstract
INTRODUCTION Endogenous or exogenous (corticosteroid-induced) glucocorticoids (GCs) excess represents, together with diabetes, the most common cause of secondary osteoporosis. AREAS COVERED We present a comprehensive overview about the pathophysiology, clinical management and treatment of GCs induced osteoporosis (GIOP). According to PRISMA guidelines, a literature search identifying articles about bone and GCs was done. EXPERT OPINION Despite the progress over the years and the increase in therapeutic options, there still are controversial issues about the management of GIOP. These mainly include the failure of BMD or FRAX to completely account for the rapid increase in fracture risk of most GC-treated patients, the understanding about the independent contribution on bone fragility of the underlying disease requiring GCs therapy, and the necessity of clearer information about the anti-fracture efficacy and long term-safety of most therapeutic options. Moreover, there are no specific indications for the management of bone fragility in endogenous hypercortisolism. Notwithstanding the above limitations there is a general consensus to recommend an assessment of fracture risk in all individuals >40 years committed to receive (or continuing) high dose (>7.5 mg of prednisone equivalent) GCs for ≥3 months and in all patients with fragility fracture history.

Abstract
Background: Antiretroviral therapy (ART) initiation is associated with decreases in bone mineral density (BMD).Objectives: To plan for a larger trial, we sought to obtain preliminary estimates for the difference in the change in BMD at 48 weeks achieved with 24 weeks of prophylactic alendronate/vitamin D during ART initiation compared to no intervention, the within-group standard deviation of this change, and intra-patient correlation coefficient for repeated BMDs. Secondary objectives included assessing enrollment feasibility, treatment acceptability, adherence and safety.Methods: We randomized treatment-naïve HIV-positive adults initiating tenofovir disoproxil fumarate/emtricitabine/elvitegravir/cobicistat or abacavir/lamivudine/dolutegravir 1:1:1 to immediate alendronate/vitamin D3 70 mg/5600 IU for 24 weeks (concomitant treatment arm, CTA), the same intervention starting 24 weeks after study entry (delayed treatment arm, DTA), or no bone anti-resorptive therapy (standard of care, SOC). We assessed BMD, acceptability, adverse events and drug adherence at baseline, week 24 and week 48.Results: Of 29 included participants, 72% initiated TDF/FTC/ELV/c and 28% initiated ABC/3TC/DTG. Median (IQR) CD4 count was 388 (303,525) cells/mm3 and median plasma HIV RNA was 4.45 (2.26, 4.84) log10 copies/mL. The mean (SD) percentage change in BMD for the CTA and DTA combined was 1.95% (2.53%), 0.38% (3.34%), and -0.57% (3.50%) at the lumbar spine, femoral neck and total hip respectively at 48 weeks. The ICC among repeated measurements of BMD was 0.978, 0.964, and 0.967 at these sites, respectively. Enrollment feasibility, drug acceptability, adherence, and tolerability were good.Conclusions: Our findings inform the sample size for a larger trial of bone anti-resorptive therapy during ART initiation and support feasibility.

Abstract
INTRODUCTION Glucocorticoid (GC) induced osteoporosis (GIOP) is the most common form of secondary osteoporosis. It develops in a dose and time dependent manner, due to a rapid and transient increase in bone resorption, followed by the inhibition of bone formation. AREAS COVERED In this review, the authors summarize the pathophysiology of GIOP and give discussion to the clinical management of patients taking GCs, focusing on the currently available drugs that have antiresorptive or anabolic activity on bone. EXPERT OPINION Despite the widespread use of GCs and their well-established detrimental skeletal effects, GIOP remains an under-diagnosed and under-treated condition. Indeed, the clinical management of GIOP is still debated, so that the recent guidelines differ in their indications for pharmacological intervention. Either bone mineral density (BMD) or algorithms such as FRAX do not completely account for the remarkable and rapid increase in fracture risk of most GC-treated patients. Moreover, while oral bisphosphonates remain the most used and cost-effective option, the potential increased benefits of more potent antiresorptive agents (e.g. denosumab and zoledronate) or anabolic compounds (e.g. teriparatide) warrant further investigation. Despite the above limitations, the assessment of fracture risk is recommended for all individuals committed to receiving oral GCs for 3 months or longer.

Abstract
CONTEXT The evidence about benefits and harms of drugs for glucocorticoid (GC)-induced osteoporosis (GIOP) is limited, and the comparative efficacy and safety of first-line and second-line agents to prevent GC-induced (GI) fractures remains unclear. OBJECTIVE To assess the comparative clinical efficacy, safety, and tolerability of first-line and second-line agents in preventing GI fractures. DATA SOURCES We searched 3 different databases through March 5, 2019. STUDY SELECTION We included randomized controlled trials enrolling patients receiving long-term GCs and compared a first-line and second-line agent with one another and with placebo. DATA EXTRACTION Two reviewers independently extracted study and participant characteristics and outcome data. DATA SYNTHESIS We performed multivariate random-effects network meta-analyses including base, 3 subgroups, and 12 sensitivity analyses. We included 22 papers from 19 unique trials involving 4328 patients receiving GCs. Teriparatide (risk ratio [RR] 0.11, 95% confidence interval [CI] 0.03-0.47), denosumab (RR 0.21, 95% CI 0.09-0.49), and risedronate (RR 0.33, 95% CI 0.19-0.58) reduced the risk of GI vertebral fractures, and the former 2 were the most efficacious according to violin plots including the surface under the cumulative ranking curve values calculated by base and sensitivity analyses. Oral alendronate (RR 0.33, 95% CI 0.12-0.93) reduced this risk in patients receiving GCs with at least 7.5 mg/day, while intravenous ibandronate (RR 0.25, 95% CI 0.06-0.99) was efficacious for the primary prevention of GIOP. Six drugs were similar in terms of the 5 other outcomes. CONCLUSIONS In terms of clinical efficacy and safety, second-line teriparatide and denosumab pose a challenge to first-line oral bisphosphonates for prevention of GI fractures.

Abstract
Glucocorticoid-induced osteoporosis (GIOP) is the most common form of secondary
osteoporosis. To date, six large randomized controlled clinical trials on the
efficacy of pharmaceutical treatment in GIOP have been conducted. All of these
studies have focused predominately on bone mineral density outcomes, and none of
them have been statistically powered to address fracture endpoints. The purpose
of this review is to highlight differences in the design and results within
these large randomized GIOP clinical trials, and how these differences might
affect clinical decisions. Differences between studies in trial design,
populations studied, and variable efficacy impact the comparability and
generalizability of these findings, and ultimately should affect practitioners’
behavior. We review the clinical trials that provide the best quality evidence
on comparative efficacy and safety of GIOP treatments. We also propose
suggestions on the design of future GIOP clinical trials with attention to
improved generalizability, and, ideally, study designs that might achieve
fracture outcomes.

Abstract
Glucocorticoids remain widely used for many medical conditions, and fractures are the most serious common adverse event related to long-term glucocorticoid use. Glucocorticoid-induced osteoporosis (GIOP) develops in a time- and dose-dependent manner, but even at low doses, an increased risk of fragility fracture may be observed even within the first month of treatment. GIOP is mediated by multiple pathophysiologic mechanisms resulting in an inhibition of bone formation and an increase in bone resorption. The clinical assessment of GIOP has potential pitfalls since dual-energy X-ray absorptiometry (DXA) may underestimate the risk of fracture in patients treated with glucocorticoids. Many national organizations have developed guidelines for assessing fracture risk and treating patients with, or at risk for, GIOP. These groups advocate both antiresorptive agents and bone-forming agents based predominately on their efficacy in improving bone mineral density. Oral bisphosphonates are generally the first-line therapy for GIOP in most patients due to their proven efficacy, good safety, and low cost. For those patients at greater risk of fracture, teriparatide should be considered earlier, based on its ability to significantly reduce vertebral fractures when compared with alendronate. GIOP remains a major public health concern that is at least partially preventable with current and potential future therapeutic options.

Denosumab Versus Risedronate in Glucocorticoid-Induced Osteoporosis: Final Results of a Twenty-Four-Month Randomized, Double-Blind, Double-Dummy Trial. Arthritis Rheumatol 2019; 71:1174-1184. [PMID: 30816640 PMCID: PMC6619388 DOI: 10.1002/art.40874] [Citation(s) in RCA: 84] [Impact Index Per Article: 16.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2018] [Accepted: 02/26/2019] [Indexed: 12/22/2022]
Abstract
Objective Clinical trial results have shown that, in glucocorticoid‐treated patients, treatment with denosumab 60 mg subcutaneously once every 6 months (Q6M) increased spine and hip bone mineral density (BMD) at month 12 significantly more than treatment with risedronate 5 mg orally once daily (QD). The present analysis was performed to compare efficacy and characterize safety through month 24. Methods This phase III study enrolled men and women ≥18 years old who had received ≥7.5 mg daily prednisone or equivalent for <3 months (glucocorticoid‐initiating) or for ≥3 months (glucocorticoid‐continuing) before screening. All patients <50 years old had a history of osteoporotic fracture. Glucocorticoid‐continuing patients ≥50 years old had T scores of −2.0 or less (or −1.0 or less with fracture history). Patients were randomized (1:1) to receive denosumab 60 mg subcutaneously Q6M or risedronate 5 mg orally QD for 24 months, with daily calcium and vitamin D. Results Of 795 patients, 590 (74.2%) completed the study (in the glucocorticoid‐initiating group, 109 of 145 patients treated with denosumab and 117 of 145 patients treated with risedronate; in the glucocorticoid‐continuing group, 186 of 253 patients treated with denosumab and 178 of 252 patients treated with risedronate). Denosumab was superior to risedronate in increasing lumbar spine and total hip BMD at all time points assessed, among glucocorticoid‐initiating patients (24‐month lumbar spine: BMD increase of 6.2% versus 1.7%, respectively [P < 0.001]; 24‐month total hip: BMD increase of 3.1% versus 0.0% [P < 0.001]) and among glucocorticoid‐continuing patients (24‐month lumbar spine: BMD increase of 6.4% versus 3.2% [P < 0.001]; 24‐month total hip: BMD increase of 2.9% versus 0.5% [P < 0.001]). Adverse events, serious adverse events (including infections), and fractures were similar between treatment groups. Conclusion Denosumab was superior to risedronate in terms of increases in spine and hip BMD through month 24, and the safety profile was similar between treatment groups. Denosumab may offer a new osteoporosis treatment option for glucocorticoid‐treated patients.

Abstract
Background To develop guidelines and recommendations to prevent and treat glucocorticoid (GC)-induced osteoporosis (GIOP) in Korea. Methods The Korean Society for Bone and Mineral Research and the Korean College of Rheumatology have developed this guideline based on Guidance for the Development of Clinical Practice Guidelines ver. 1.0 established by the National Evidence-Based Healthcare Collaborating Agency. This guideline was developed by adapting previously published guidelines, and a systematic review and quality assessment were performed. Results This guideline applies to adults aged ≥19 years who are using or plan to use GCs. It does not include children and adolescents. An initial assessment of fracture risk should be performed within 6 months of initial GC use. Fracture risk should be estimated using the fracture-risk assessment tool (FRAX) after adjustments for GC dose, history of osteoporotic fractures, and bone mineral density (BMD) results. All patients administered with prednisolone or an equivalent medication at a dose ≥2.5 mg/day for ≥3 months are recommended to use adequate calcium and vitamin D during treatment. Patients showing a moderate-to-high fracture risk should be treated with additional medication for osteoporosis. All patients continuing GC therapy should undergo annual BMD testing, vertebral X-ray, and fracture risk assessment using FRAX. When treatment failure is suspected, switching to another drug should be considered. Conclusions This guideline is intended to guide clinicians in the prevention and treatment of GIOP.

Abstract
BACKGROUND Alendronate has been used to prevent or treat glucocorticoid-induced osteoporosis (GIO), data regarding its efficacy are inconsistent. We conducted the current systematic review and meta-analysis to evaluate both efficacy and safety of alendronate in the treatment of GIO. METHODS PubMed, Embase, the Cochrane Controlled Trials Registry, and the China Academic Journal Network Publishing Databases were searched up through March 1, 2018. Randomized controlled trials (RCTs) involving patients which received alendronate treatment were included. Outcome measures were bone mineral density (BMD) changes, bone fractures, and adverse reactions. Data from the individual studies were pooled using random or fixed effect models based on heterogeneity. Effect size was reported as standardized mean differences (SMD) for continuous outcomes and pooled odds ratios (OR) for dichotomous outcomes, with 95% confidence interval (CI). RESULTS Overall, 10 studies involving 1002 patients were included in the present investigation. Alendronate treatment significantly increased BMD of the lumbar spine and femoral neck during 6 to 24 months. These beneficial effects were apparent at 12 months after treatment for the lumbar spine but not the femoral neck BMD. Alendronate treatment did not significantly change fracture risk nor induce significant differences in adverse gastrointestinal effects. CONCLUSION Alendronate significantly increases BMD of the lumbar spine and femoral neck in patients with GIO, but does not appear to reduce the risk of fractures. As relatively insufficient data regarding the GIO fracture incidence has been reported, more RCTs need to be carried out to determine the efficacy of alendronate in the prevention of GIO fracture.

Abstract
Glucocorticoids (GCs) are widely used to treat chronic diseases. Prolonged and/or overdose administration of GCs has many side-effects to human health including GC-induced osteoporosis (GIOP). In this investigation, the objective was to assess the influence that echinacoside (ECH) exerts upon dexamethasone-treated murine osteoblastic MC3T3-E1 cells. We found that ECH (5, 10, 20 and 40 mg/l) inhibited dexamethasone (1,000 nM)-suppressed cell viability as demonstrated by Cell Counting Kit-8 (CCK-8) assay. The dose of 10 mg/l was selected for the following experiments because this dose had a better effect than the dose of 5 mg/l, and the doses >10 mg/l had a similar effect as this dose. ECH (10 mg/l) or pifithrin-α (PFT-α) (a p53 inhibitor, 20 µM) suppressed dexamethasone-induced MC3T3-E1 apoptosis as illustrated by Annexin V/propidium iodide (PI) double-labeling flow cytometry analysis. ECH or PFT-α treatment also alleviated dexamethasone's action of inhibiting Bcl-2 expression as well as dexamethasone's action of stimulating on the expression of p53 and Bax. Moreover, lentivirus mediated-p53 overexpression reversed the effects of ECH in dexamethasone-treated MC3T3-E1 cells, suggesting that ECH induced anti-apoptotic effects in dexamethasone-treated osteoblasts via p53-dependent pathway. In summary, ECH has a protective effect against osteoblastic cell apoptosis induced by dexamethasone, suggesting that ECH may have potentials for clinical application in the treatment of GIOP.

Abstract
Glucocorticoid-induced osteoporosis is the most common secondary cause of osteoporosis and the resulting fractures cause significant morbidity. Following initiation of oral glucocorticoids, rapid bone loss occurs, and fracture risk increases within a few months in a dose-dependent manner. These adverse effects are due to inhibition of bone formation accompanied by an early but transient increase in bone resorption. Multiple mechanisms underlie these changes in bone remodeling; direct effects include upregulation of PPARγR2, increased expression of sclerostin and increased RANKL/OPG ratio, whilst hypogonadism, altered renal and intestinal calcium handling, and reduced production of insulin-like growth factor 1 also contribute. Fracture risk assessment should be performed as soon as possible after glucocorticoids are initiated and bone protective therapy started promptly in individuals at high-risk, with calcium and vitamin D supplements where appropriate. Oral bisphosphonates are currently regarded as first line options on the grounds of their low cost. However, teriparatide has been shown to be superior in its effects on BMD and vertebral fracture risk in glucocorticoid-treated individuals with osteoporosis and should be considered as an alternative first line option in high-risk patients.

Abstract
Purpose To evaluate the incidence of fragility fractures associated with high-dose glucocorticoid therapy in patients with systemic rheumatic disease. METHODS A retrospective study of patients who were treated with high-dose prednisolone (> 0.8 mg/kg) for systemic rheumatic disease at Kobe University Hospital from April 1988 to March 2012. The primary outcome was a major osteoporotic fracture (defined as a clinical vertebral, hip, forearm, or proximal humerus fracture) after high-dose glucocorticoid therapy. For postmenopausal women and men over 40 of age, the patient's fracture risk at the beginning of high-dose glucocorticoid therapy was assessed by the World Health Organization's Fracture Risk Assessment Tool (FRAX®). Results Of 229 patients (median age: 49 years), 57 suffered a fragility fracture during the observation period (median observation period: 1558 days). Of 84 premenopausal patients, 5 suffered a fracture. In contrast, of 86 postmenopausal female, 36 suffered a fracture. Fragility fractures were far more frequent than predicted by the FRAX® score. Patients with FRAX® scores over 8.3% had a particularly high risk of fracture. Conclusions Fragility fractures associated with high-dose glucocorticoid therapy are common among postmenopausal women. Extreme care should be taken especially for postmenopausal women when high-dose glucocorticoid therapy is required.

Abstract
Objectives This Clinical Guidance is aimed to help practitioners assess, diagnose and manage their patients with glucocorticoid-induced osteoporosis (GIO), using the best available evidence. Methods A literature search using PubMed (MEDLINE) and The Cochrane Library identified all relevant articles on GIO and its assessment, diagnosis and treatment, from 2011, to update from the 2012 edition. The studies were assessed and the level of evidence assigned. For each statement, studies with the highest level of evidence were used to frame the recommendation. Results Consider treatment early in all patients on glucocorticoids (GC) as fracture risk increases within 3–6 months of starting GC. The decision to start treatment for GIO depends on the presence of prior fracture, category of risk (as calculated using Fracture Risk Assessment Tool), daily dose and duration of GC treatment, age, and menopausal status. General measures include adequate calcium and vitamin D intake and reducing the dose of GC to the minimum required to achieve disease control. In patients on GC with osteoporotic fractures or confirmed osteoporosis on dual-energy X-ray absorptiometry, bisphosphonates are the first-line treatment. Treatment should be continued as long as patients remain on GC. Algorithms for the management of GIO in both pre- and post-menopausal women and men have been updated. Conclusions In post-menopausal women and men above 50 years, bisphosphonates remain the mainstay of treatment in GIO. In pre-menopausal women and men below 50 years, bisphosphonates are recommended for those with a prevalent fracture or at very high risk only.

Abstract
OBJECTIVE The purpose of this study was to evaluate the effect of bisphosphonates in improving bone mineral density (BMD) and decreasing the occurrence rate of fractures and adverse events in patients with inflammatory bowel disease (IBD). METHODS Randomized controlled trials (RCTs) which use bisphosphonates in IBD patients were identified in PubMed, MEDLINE database, EMBASE database, Web of Knowledge, and the Cochrane Databases between 1990 and June 2016. People received bisphosphonate or placebos with a follow-up of at least one year were also considered. STATA 12.0 software was used for the meta-analysis. RESULTS Eleven randomized clinical trials were included in the meta-analysis. The data indicated that the percentage change in the increased BMD in the bisphosphonates groups was superior to that of the control groups at the lumbar spine and total hip. At the femoral neck, there was no significant difference between the two groups. The incidence of new fractures during follow-up showed significant reduction. The adverse event analysis revealed no significant difference between the two groups. CONCLUSION Our results demonstrate that bisphosphonates therapy has an effect on bone loss in patients with IBD but show no evident efficiency at increasing the incidence of adverse events.

Abstract
Treatment of diffuse large B-cell lymphoma (DLBCL) with R-CHOP(-like) regimens include large cumulative doses of prednisolone. In this retrospective study, we evaluated changes in vertebral bone density (VD) in DLBCL patients by measuring CT-ascertained Hounsfield units (HU) at the L3 level. In total, 111 patients diagnosed from 2007 to 2012 and response assessed following first line treatment were included. Post-treatment VD was significantly reduced to 86% of pretreatment VD on average (p < .001). Neither female sex nor high age (>70 years) were significantly associated with greater post-treatment VD reduction. Two years after completing R-CHOP treatment, VD remained significantly lower than baseline VD (p < .001). Vertebral compression fractures visualized by CT were found in 16/111 patients (14%) during follow-up. In conclusion, bone mineral density is significantly reduced following R-CHOP(-like) treatment and vertebral compression fractures are common. Glucocorticoid-induced osteoporosis may therefore have impact on survivorship for the large fraction of DLBCL patients with durable remissions.

Abstract
BACKGROUND This is an update of a Cochrane Review first published in 1999. Corticosteroids are widely used in inflammatory conditions as an immunosuppressive agent. Bone loss is a serious side effect of this therapy. Several studies have examined the use of bisphosphonates in the prevention and treatment of glucocorticosteroid-induced osteoporosis (GIOP) and have reported varying magnitudes of effect. OBJECTIVES To assess the benefits and harms of bisphosphonates for the prevention and treatment of GIOP in adults. SEARCH METHODS We searched CENTRAL, MEDLINE and Embase up to April 2016 and International Pharmaceutical Abstracts (IPA) via OVID up to January 2012 for relevant articles and conference proceedings with no language restrictions. We searched two clinical trial registries for ongoing and recently completed studies (ClinicalTrials.gov and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) search portal). We also reviewed reference lists of relevant review articles. SELECTION CRITERIA We included randomised controlled trials (RCTs) satisfying the following criteria: 1) prevention or treatment of GIOP; 2) adults taking a mean steroid dose of 5.0 mg/day or more; 3) active treatment including bisphosphonates of any type alone or in combination with calcium or vitamin D; 4) comparator treatment including a control of calcium or vitamin D, or both, alone or with placebo; and 4) reporting relevant outcomes. We excluded trials that included people with transplant-associated steroid use. DATA COLLECTION AND ANALYSIS At least two review authors independently selected trials for inclusion, extracted data, performed 'risk of bias' assessment and evaluated the certainty of evidence using the GRADE approach. Major outcomes of interest were the incidence of vertebral and nonvertebral fractures after 12 to 24 months; the change in bone mineral density (BMD) at the lumbar spine and femoral neck after 12 months; serious adverse events; withdrawals due to adverse events; and quality of life. We used standard Cochrane methodological procedures. MAIN RESULTS We included a total of 27 RCTs with 3075 participants in the review. Pooled analysis for incident vertebral fractures included 12 trials (1343 participants) with high-certainty evidence and low risk of bias. In this analysis 46/597 (or 77 per 1000) people experienced new vertebral fractures in the control group compared with 31/746 (or 44 per 1000; range 27 to 70) in the bisphosphonate group; relative improvement of 43% (9% to 65% better) with bisphosphonates; absolute increased benefit of 2% fewer people sustaining fractures with bisphosphonates (5% fewer to 1% more); number needed to treat for an additional beneficial outcome (NNTB) was 31 (20 to 145) meaning that approximately 31 people would need to be treated with bisphosphonates to prevent new vertebral fractures in one person.Pooled analysis for incident nonvertebral fractures included nine trials with 1245 participants with low-certainty evidence (downgraded for imprecision and serious risk of bias as a patient-reported outcome). In this analysis 30/546 (or 55 per 1000) people experienced new nonvertebral fracture in the control group compared with 29/699 (or 42 per 1000; range 25 to 69) in the bisphosphonate group; relative improvement of 21% with bisphosphonates (33% worse to 53% better); absolute increased benefit of 1% fewer people with fractures with bisphosphonates (4% fewer to 1% more).Pooled analysis on BMD change at the lumbar spine after 12 months included 23 trials with 2042 patients. Eighteen trials with 1665 participants were included in the pooled analysis on BMD at the femoral neck after 12 months. Evidence for both outcomes was moderate-certainty (downgraded for indirectness as a surrogate marker for osteoporosis) with low risk of bias. Overall, the bisphosphonate groups reported stabilisation or increase in BMD, while the control groups showed decreased BMD over the study period. At the lumbar spine, there was an absolute increase in BMD of 3.5% with bisphosphonates (2.90% to 4.10% higher) with a relative improvement of 1.10% with bisphosphonates (0.91% to 1.29%); NNTB 3 (2 to 3). At the femoral neck, the absolute difference in BMD was 2.06% higher in the bisphosphonate group compared to the control group (1.45% to 2.68% higher) with a relative improvement of 1.29% (0.91% to 1.69%); NNTB 5 (4 to 7).Pooled analysis on serious adverse events included 15 trials (1703 participants) with low-certainty evidence (downgraded for imprecision and risk of bias). In this analysis 131/811 (or 162 per 1000) people experienced serious adverse events in the control group compared to 136/892 (or 147 per 1000; range 120 to 181) in the bisphosphonate group; absolute increased harm of 0% more serious adverse events (2% fewer to 2% more); a relative per cent change with 9% improvement (12% worse to 26% better).Pooled analysis for withdrawals due to adverse events included 15 trials (1790 patients) with low-certainty evidence (downgraded for imprecision and risk of bias). In this analysis 63/866 (or 73 per 1000) people withdrew in the control group compared to 76/924 (or 77 per 1000; range 56 to 107) in the bisphosphonate group; an absolute increased harm of 1% more withdrawals with bisphosphonates (95% CI 1% fewer to 3% more); a relative per cent change 6% worse (95% CI 47% worse to 23% better).Quality of life was not assessed in any of the trials. AUTHORS' CONCLUSIONS There was high-certainty evidence that bisphosphonates are beneficial in reducing the risk of vertebral fractures with data extending to 24 months of use. There was low-certainty evidence that bisphosphonates may make little or no difference in preventing nonvertebral fractures. There was moderate-certainty evidence that bisphosphonates are beneficial in preventing and treating corticosteroid-induced bone loss at both the lumbar spine and femoral neck. Regarding harm, there was low-certainty evidence that bisphosphonates may make little or no difference in the occurrence of serious adverse events or withdrawals due to adverse events. We are cautious in interpreting these data as markers for harm and tolerability due to the potential for bias.Overall, our review supports the use of bisphosphonates to reduce the risk of vertebral fractures and the prevention and treatment of steroid-induced bone loss.

Abstract
Abstract Introduction Different rates of resorption are mediated by osteoclasts that may be affected by bisphosphonates during bone graft repair. Bisphosphonates are drugs that act as inhibitors of bone resorption. Objective The aim of the present study was to evaluate the rate of resorption of skullcap grafts in rabbits with and without the use of alendronate sodium. Material and method Thirty two New Zealand rabbits were divided into two groups (control group and alendronate group) and divided again into four periods (7, 14, 30 and 60 days). The control group did not receive alendronate, while animals of the experimental group received 4 mg of alendronate sodium weekly after the surgery. An 8 mm diameter bone block was removed from the parietal bone and fixed by screws to the contralateral parietal bone. During the periods of 7, 14, 30 and 60 days, the animals had undergone euthanasia and samples were removed for further analysis. Morphological and histomorphometric tests were used to compare graft thicknesses and to evaluate the newly formed bone at the interface between the graft and receptor site. The Wilcoxon and Mann-Whitney tests were used for statistical analyses. Result All grafts healed and integrated uneventfully and no statistically significant differences in resorption rates or bone deposition were detected after the final incorporation of the graft in both groups. Conclusion Alendronate Sodium did not decrease the bone graft resorption rates, but there was a tendency for better results in the control group regarding the resorption and neoformation in autogenous calvarial bone grafts in rabbits.

Abstract
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 trochanter, and is not associated with an increased incidence of gastrointestinal adverse events; however, the vertebral and nonvertebral fractures cannot be reduced. However, the results should be interpreted with caution due to the poor statistical power.

Abstract
INTRODUCTION Glucocorticoid-induced osteoporosis (GIOP) is the most common type of secondary osteoporosis. Patient selection and the treatment choice remain to be controversial. None of the proposed management guidelines are widely accepted. We evaluate the available clinical data, the efficacy of current medication and we propose an overall algorithm for managing GIOP. AREAS COVERED This article provides a critical review of in vivo and clinical evidence regarding GIOP and developing evidence-based algorithm of treatment. Data base used includes MEDLINE® (1950 to May 2014). EXPERT OPINION Patient-specific treatment is the gold standard of care. Glucocorticoid (GC)-treated patients must comply with a healthy lifestyle and receive 1000 mg of calcium and at least 800 mg of Vitamin D daily. Bisphosphonate (BP) therapy is the current standard of care for prevention and treatment of GIOP. Most of bisphosphonates demonstrated benefit in lumbar bone mineral density (BMD) and some in hip BMD. Alendronate, risedronate and zoledronate showed vertebral anti-fracture efficacy in postmenopausal women and men. Scarce data however when compared head to head with BP efficacy. In post-menopausal women, early antiresorptive BP treatment appears to be efficient and safe. In premenopausal women and patients at high risk of fracture receiving long-term GC therapy however, teriparitide may be advised alternatively.

Abstract
Beta-ecdysone (βEcd) is a phytoecdysteroid found in the dry roots and seeds of the asteraceae and achyranthes plants, and is reported to increase osteogenesis in vitro. Since glucocorticoid (GC) excess is associated with a decrease in bone formation, the purpose of this study was to determine if treatment with βEcd could prevent GC-induced osteoporosis. Two-month-old male Swiss-Webster mice (n=8-10/group) were randomized to either placebo or slow release prednisolone pellets (3.3mg/kg/day) and treated with vehicle control or βEcd (0.5mg/kg/day) for 21days. GC treatment inhibited age-dependent trabecular gain and cortical bone expansion and this was accompanied by a 30-50% lower bone formation rate (BFR) at both the endosteal and periosteal surfaces. Mice treated with only βEcd significantly increased bone formation on the endosteal and periosteal bone surfaces, and increased cortical bone mass were their controls to compare to GC alone. Concurrent treatment of βEcd and GC completely prevented the GC-induced reduction in BFR, trabecular bone volume and partially prevented cortical bone loss. In vitro studies determined that βEcd prevented the GC increase in autophagy of the bone marrow stromal cells as well as in whole bone. In summary, βEcd prevented GC induced changes in bone formation, bone cell viability and bone mass. Additional studies are warranted of βEcd for the treatment of GC induced bone loss.

Abstract
Osteoporosis in men causes significant morbidity and mortality. Bone health declines gradually, often insidiously; and in light of the advancing aging population poses a serious public health issue that is not well recognized. Studies of the past decade have expanded our understanding of the events within, as well as the regulation of, bone remodeling and provided better insight into the physiology and pathophysiology specific to the adult male skeleton. The clinical measurement of bone mineral density using dual-energy X-ray absorptiometry remains the gold standard for diagnosis of osteoporosis in males; and fracture risk assessment is now recognized as a preferred approach to guide treatment decisions. Utilizing surrogate end-points such as increasing bone mineral density and decreasing concentrations of bone resorption markers, clinical trials have demonstrated efficacy in pharmacological treatment of osteoporosis in the adult male. Unfortunately, few studies have evaluated the anti-fracture benefits in this population. Measurement of bone turnover markers may be an additional tool to monitor therapeutic responsiveness in addition to the measurement of bone mineral density.

Abstract
Glucocorticoids (GCs) are highly effective in the treatment of inflammatory and autoimmune conditions but their therapeutic use is limited by numerous adverse effects. Recent insights into the mechanisms of action of both endogenous and exogenous GCs on bone cells have unlocked new approaches to the development of effective strategies for the prevention and treatment of GC-induced osteoporosis. Furthermore, topical studies in rodents indicate that the osteoblast-derived peptide, osteocalcin, plays a central role in the pathogenesis of GC-induced diabetes and obesity. These exciting findings mechanistically link the detrimental effects of GCs on bone and energy metabolism. In this article we review the physiology and pathophysiology of GC action on bone cells, and discuss current and emerging concepts regarding the molecular mechanisms underlying adverse effects of GCs such as osteoporosis and diabetes.

Abstract
PURPOSE Both HIV infection and antiretroviral therapy (ART) are associated with significant decreases in bone mineral density (BMD) and increased fracture rates. To prepare for a randomized controlled trial of prophylactic bone antiresorptive therapy during ART initiation, we assessed the acceptability of this strategy, bone health knowledge, and fracture risk among HIV-infected adults. METHODS HIV-infected adults with no history of osteoporosis were recruited from one tertiary and one primary care HIV clinic. Participants completed a questionnaire and underwent chart review. The primary outcome was the proportion of respondents expressing interest in taking prophylactic bone antiresorptive therapy in conjunction with ART. RESULTS Of 112 respondents, 25.0% were ART naïve, 23.2% had been taking ART for ≤1 year, and 51.8% had been taking ART for >1 year. Half (51.9%) indicated interest in taking short-course prophylactic bone antiresorptive therapy; this did not differ by ART status (53.6% among ART-naïve, 51.3% among ART-treated; P=0.84, chi-square test). In exploratory multivariable analysis adjusted for ART status, a greater number of pills taken per day was positively associated with this outcome (adjusted odds ratio [OR] =1.12 per pill, 95% confidence limit [CL] =1.01, 1.25), while male sex was inversely associated (adjusted OR =0.05, 95% CL =0.01, 0.24). Among those willing to take therapy, most (80.4%) were willing to do so for "as long as needed" and preferred weekly dosing (70.9%) to daily dosing (12.7%). CONCLUSIONS Half of this sample would be willing to take bone antiresorptive therapy together with ART, with preferences for weekly dosing and for whatever duration may be required. These data will inform the design of future trials to protect bone health in HIV.

Abstract
Osteoporosis in men contributes to significant morbidity and mortality. Hip fractures in men are associated with greater mortality compared with women, with a mortality rate of up to 37.5% within a year following the fracture. Its timely diagnosis and treatment are therefore essential. However, despite one-third of all hip fractures worldwide occurring in men, osteoporosis in men remains an immensely under-recognized and undertreated public health problem. Bisphosphonates are well studied first-line treatments for postmenopausal women with osteoporosis and have been shown to reduce fragility fractures at all clinically important sites (vertebral, nonvertebral, hip and wrist). However, the majority of studies of oral or intravenous bisphosphonate therapy in men with osteoporosis report effects on surrogate markers, including bone mineral density (BMD) and biochemical bone turnover markers, rather than on fragility fractures. Oral or intravenous bisphosphonate therapy increases spinal, total hip and femoral neck BMD compared with placebo in men with osteoporosis. Both bone resorption and bone formation markers are decreased following bisphosphonate therapy, with the onset of the decrease in bone formation markers being delayed. In a study of intravenous zoledronic acid given to older men and women following a hip fracture, any clinical vertebral and nonvertebral fractures were all reduced compared with placebo infusions. In addition, mortality was reduced in patients who received zoledronic acid. Recent studies in men with osteoporosis have increasingly reported reductions in incident vertebral fractures with oral or intravenous bisphosphonate therapy, although all studies have been underpowered to detect effects on nonvertebral and hip fracture outcomes. Bisphosphonates have a role as monotherapy, as consolidative therapy after a course of teriparatide therapy, or in combination with testosterone replacement in men with hypogonadism and osteoporosis. Bisphosphonate therapy is validated and important in the treatment of osteoporosis in men.
