Hwang J, Lee EK, Ahn JK, Cha HS, Koh EM, Lee J. Bone-density testing interval and transition to osteoporosis in patients with rheumatoid arthritis. Osteoporos Int 2017; 28:231-237. [PMID: 27509834 DOI: 10.1007/s00198-016-3703-7] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/04/2016] [Accepted: 07/06/2016] [Indexed: 01/30/2023]
Abstract
UNLABELLED The study aims to evaluate the rate of transition to osteoporosis in 360 RA patients and estimate the rescreening intervals of bone mineral density (BMD) testing. Osteoporosis was newly developed in 24.8 % during mean follow-up of 7.4 years. The estimated time of a BMD testing interval was dependent on the baseline T-score in RA patients. INTRODUCTION Although BMD testing is routinely performed in RA patients, the interval between BMD tests has not been determined. METHODS We retrospectively recruited 360 consecutive female patients with RA, who underwent repeated BMD testing, with a mean age of 53.7 ± 10.2 years and a mean follow-up duration of 7.4 ± 5.0 years. We stratified the study participants into five groups based on their baseline T-score range. The testing interval was defined as the estimated time for 10 % of patients in each subgroup to transition to osteoporosis. Competing-risk analyses were performed with sensitivity analysis by menopausal status and risk factors for transition to osteoporosis. RESULTS At baseline, 15 % of screened patients had osteoporosis, and during follow-up, that proportion increased to 24.8 %. The estimated BMD testing interval for 10 % of patients to develop osteoporosis was 9.6 years for those with normal BMD, 7.6 years for those with mild osteopenia, 4.7 years for those with moderate osteopenia, and 2.1 years for those with severe osteopenia. No significant risk factor for transition to osteoporosis was identified in this cohort. CONCLUSIONS Our data indicate that osteoporosis will develop in less than 10 % of female RA patients during rescreening intervals of approximately 9 years for those with normal bone density at baseline, 7 years for those with mild osteopenia, 4 years for those with moderate osteopenia, and 2 years for those with severe osteopenia at baseline. BMD interval in RA patients could be adjusted according to their baseline BMD T-scores.

Access to fracture risk assessment by FRAX and linked National Osteoporosis Guideline Group (NOGG) guidance in the UK-an analysis of anonymous website activity. Osteoporos Int 2017; 28:71-76.

Abstract
UNLABELLED In the UK, fracture risk guidance is provided by the National Osteoporosis Guideline Group (NOGG). NOGG usage showed widespread access through direct web-based linkage to FRAX. The facilitated interaction between fracture risk assessment and clinical guidelines could usefully be adopted in other countries. INTRODUCTION In the UK, guidance on assessment of osteoporosis and fracture risk is provided by the National Osteoporosis Guideline Group ( www.shef.ac.uk/NOGG ). We wished to determine access to this guidance by exploring website activity. METHODS We undertook an analysis of FRAX and NOGG website usage for the year between 1st July 2013 and 30th June 2014 using Google Analytics software. RESULTS During this period, there was a total of 1,774,812 sessions (a user interaction with the website) on the FRAX website with 348,964 of these from UK-based users; 253,530 sessions were recorded on the NOGG website. Of the latter, two-thirds were returning visitors, with the vast majority (208,766; 82 %) arising from sites within the UK. The remainder of sessions were from other countries demonstrating that some users of FRAX in other countries make use of the NOGG guidance. Of the UK-sourced sessions, the majority was from England, but the session rate (adjusted for population) was the highest for Scotland. Almost all (95.7 %) of the UK sessions arose from calculations being passed through from the FRAX tool ( www.shef.ac.uk/FRAX ) to the NOGG website, comprising FRAX calculations in patients without a bone mineral density (BMD) measurement (74.5 %) or FRAX calculations with a BMD result (21.2 %). National Health Service (NHS) sites were identified as the major source of visits to the NOGG website, comprising 79.9 % of the identifiable visiting locations, but this is an underestimate as many sites from within the NHS are not classified as such. CONCLUSION The study shows that the facilitated interaction between web-based fracture risk assessment and clinical guidelines is widely used in the UK. The approach could usefully be adopted in other countries for which a FRAX model is available.

Abstract
OBJECTIVE This study investigated the effects of combined ovariectomy with dexamethasone treatment on rat lumbar vertebrae in comparison with osteoporosis induced via ovariectomy or dexamethasone alone, and analysis of the associated molecular mechanism. METHODS Sixty-two female Sprague-Dawley rats (3 months' old) were randomly divided into five treatment groups: an untreated baseline (BL) group; those receiving a sham operation (SHAM); those receiving a dexamethasone injection alone (DEXA); those undergoing bilateral ovariectomy (OVX); and those subjected to both ovariectomy and dexamethasone injection (OVX-DEXA). Animals in the BL group were euthanized at the beginning of the experiment, whereas animals in the remaining groups were euthanized at the end of the first month (M1), second month (M2), or third month (M3). Bone mineral density, bone microarchitecture, biomechanical properties of vertebrae, and serum levels of estrogen, amino-terminal propeptide of type I collagen (PINP), and β-C-telopeptide of type I collagen (β-CTX) were measured. In addition, we examined biglycan, runt-related transcription factor 2 (RUNX2), osteoprotegerin (OPG), lipoprotein receptor-related protein-5 (LRP-5), cathepsin K (CTSK), and sclerostin mRNA expression. RESULTS Bone mineral content and bone mineral density were markedly lower in the OVX-DEXA group compared with the OVX group at all time points examined. The relative bone surface (BS/TV, mm(-1), relative bone volume (BV/TV,%), and trabecular number (Tb.N, 1/mm) were markedly lower in the OVX-DEXA group compared with the remaining groups, whereas trabecular separation (Tb.Sp, mm) was markedly higher in the OVX-DEXA group compared with the remaining groups at M2 or M3. The OVX-DEXA group showed lower compressive strength and lower stiffness compared with the other groups at M2 and M3. Compressive displacement and energy absorption capacity were also markedly lower in the OVX-DEXA group compared with the OVX group at M3. Estradiol levels were markedly lower in the OVX-DEXA group compared with the other groups. Biglycan, runt-related transcription factor 2, osteoprotegerin, and lipoprotein receptor-related protein-5 were down-regulated in the DEXA, OVX, and OVX-DEXA groups compared with the BL and SHAM groups, whereas cathepsin K and sclerostin were up-regulated in the OVX-DEXA group compared with the DEXA and OVX groups. CONCLUSIONS Ovariectomy combined with dexamethasone induced more serious osteoporosis in the rat lumbar spine than either ovariectomy or dexamethasone alone. The combined effect may be due to a combination of suppressed bone formation and increased bone resorption related to an estradiol deficit.

Abstract
The aim of this study was to describe compliance with select quality indicators and assess organ-specific dysfunction in a childhood-onset systemic lupus erythematosus population by using a validated damage index and to evaluate associations between compliance with quality indicators and disease damage. A retrospective chart review was performed on patients diagnosed with systemic lupus erythematosus prior to age 18 followed at a single center in the USA from 1999 to 2012 (n = 75). Data regarding quality indicators and outcome variables, including the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index, were collected. The median disease duration was 3.8 years. The proportion of patients or patient-years in which care complied with the proposed quality measures was 94.4% for hydroxychloroquine use, 84.3% for vitamin D recommendation,75.8% for influenza vaccination (patient-years), 67.2% for meningococcal vaccination, 49.0% for ophthalmologic examination (patient-years), 31.7% for pneumococcal vaccination, and 28.6% for bone mineral density evaluation. Disease damage was present in 41.3% of patients at last follow-up, with an average damage index score of 0.81. Disease damage at last follow-up was associated with minority race/ethnicity (p = 0.008), bone mineral density evaluation (p = 0.035), and vitamin D recommendation (p = 0.018). Adherence to quality indicators in a childhood-onset systemic lupus erythematosus population is varied, and disease damage is prevalent. This study highlights the importance of quality improvement initiatives aimed at optimizing care delivery to reduce disease damage in pediatric lupus patients.

Abstract
In recent years, the condition of subclinical hypercortisolism (SH) has become a topic of growing interest. This is due to the fact that SH prevalence is not negligible (0.8-2% in the general population) and that, although asymptomatic, this subtle cortisol excess is not harmless, being associated with an increased risk of complications, in particular of osteoporosis and fragility fractures. As specific symptoms of hypercortisolism are absent in SH, the SH diagnosis relies only on biochemical tests and it is a challenge for physicians. As a consequence, even the indications for the evaluation of bone involvement in SH patients are debatable and guidelines are not available. Finally, the relative importance of bone density, bone quality and glucocorticoid sensitivity in SH is a recent field of research. On the other hand, SH prevalence seems to be increased in osteoporotic patients, in whom a vertebral fracture may be the presenting symptom of an otherwise asymptomatic cortisol excess. Therefore, the issue of who and how to screen for SH among the osteoporotic patients is widely debated. The present review will summarize the available data regarding the bone turnover, bone mineral density, bone quality and risk of fracture in patients with endogenous SH. In addition, the role of the individual glucocorticoid sensitivity in SH-related bone damage and the problem of diagnosing and managing the bone consequences of SH will be reviewed. Finally, the issue of suspecting and screening for SH patients with apparent primary osteoporosis will be addressed.

Abstract
The adjusted incidence rate of hip fracture in Thailand has increased more than 31% from 1997 to 2006. Mortality and morbidity after hip fracture are also high. One year mortality after a hip fracture has increased from 18% in 1999 to 21% in 2007. The Thai Osteoporosis Foundation (TOPF) developed the first Clinical Practice Guideline (CPG) in 2002 and keeps updating the CPG since then. This latest version of the CPG is our attempt to provide comprehensive positional statement on the diagnosis, prevention and treatment of osteoporosis in Thailand. The study group who revised this position statement contains experts from the TOPF, Four Royal Colleges of Thailand, includes the Orthopaedic Surgeons, Gynecologists and Obstetricians, Physiatrists, Radiologists and 2 Associations of Endocrinologists and Rheumatologists which have involved in the management of patients with osteoporosis.

Abstract
Glucocorticoid-induced osteoporosis is the most frequent form of secondary osteoporosis caused by chronic exposure to glucocorticoid excess. Pathogenesis of glucocorticoid-induced osteoporosis is multifactorial including direct effects of glucocorticoids on bone cells and indirect effects of glucocorticoids on several neuroendocrine and metabolic pathways. Fragility fractures occur early in glucocorticoid-induced osteoporosis and anti-osteoporotic drugs along with calcium and vitamin D should be started soon after exposure to glucocorticoid excess. This paper summarizes some of the main topics discussed during the 9th Glucocorticoid-Induced Osteoporosis Meeting (Rome, April 2016) with a specific focus on the role of growth hormone/insulin-like growth factor-1 and parathyroid hormone/vitamin D axes in the pathogenesis of glucocorticoid-induced osteoporosis and the controversial aspects concerning therapeutic approach to skeletal fragility in this clinical setting.

Abstract
UNLABELLED This systematic review identified assessment guidelines for osteoporosis that incorporate FRAX. The rationale for intervention thresholds is given in a minority of papers. Intervention thresholds (fixed or age-dependent) need to be country-specific. INTRODUCTION In most assessment guidelines, treatment for osteoporosis is recommended in individuals with prior fragility fractures, especially fractures at spine and hip. However, for those without prior fractures, the intervention thresholds can be derived using different methods. The aim of this report was to undertake a systematic review of the available information on the use of FRAX® in assessment guidelines, in particular the setting of thresholds and their validation. METHODS We identified 120 guidelines or academic papers that incorporated FRAX of which 38 provided no clear statement on how the fracture probabilities derived are to be used in decision-making in clinical practice. The remainder recommended a fixed intervention threshold (n = 58), most commonly as a component of more complex guidance (e.g. bone mineral density (BMD) thresholds) or an age-dependent threshold (n = 22). Two guidelines have adopted both age-dependent and fixed thresholds. RESULTS Fixed probability thresholds have ranged from 4 to 20 % for a major fracture and 1.3-5 % for hip fracture. More than one half (39) of the 58 publications identified utilised a threshold probability of 20 % for a major osteoporotic fracture, many of which also mention a hip fracture probability of 3 % as an alternative intervention threshold. In nearly all instances, no rationale is provided other than that this was the threshold used by the National Osteoporosis Foundation of the USA. Where undertaken, fixed probability thresholds have been determined from tests of discrimination (Hong Kong), health economic assessment (USA, Switzerland), to match the prevalence of osteoporosis (China) or to align with pre-existing guidelines or reimbursement criteria (Japan, Poland). Age-dependent intervention thresholds, first developed by the National Osteoporosis Guideline Group (NOGG), are based on the rationale that if a woman with a prior fragility fracture is eligible for treatment, then, at any given age, a man or woman with the same fracture probability but in the absence of a previous fracture (i.e. at the 'fracture threshold') should also be eligible. Under current NOGG guidelines, based on age-dependent probability thresholds, inequalities in access to therapy arise especially at older ages (≥70 years) depending on the presence or absence of a prior fracture. An alternative threshold using a hybrid model reduces this disparity. CONCLUSION The use of FRAX (fixed or age-dependent thresholds) as the gateway to assessment identifies individuals at high risk more effectively than the use of BMD. However, the setting of intervention thresholds needs to be country-specific.

Abstract
OBJECTIVE Smoking adversely influences comorbidities in rheumatoid arthritis (RA). The aim of this pilot study was to investigate whether smoking cessation is increased following a 3-month smoking cessation intervention tailored for people with RA. METHODS Thirty-nine current smokers with RA were recruited. Participants were randomized into the control group to receive the current local standard of care for smoking cessation (i.e., ABC = brief advice and subsidized nicotine replacement therapy [NRT], or into the intervention group to receive ABC plus additional smoking cessation advice for 3 months (ABC+), including face-to-face, telephone, and e-mail contact. Advice was tailored to the participants' specific needs from a range of intervention tools focused on education about smoking and RA, pain control, exercise, coping, and support. The primary outcome was smoking cessation at 6 months. The secondary outcome was sustained reduction in smoking at 6 months. Disease and psychosocial characteristics of quitters and nonquitters were examined. RESULTS The overall smoking cessation rate was 24%. There was no significant difference in smoking cessation rates between the ABC and ABC+ groups (21% versus 26%; P = 0.70). The mean number of cigarettes smoked daily was reduced by 44% (P < 0.001) but did not differ between ABC and ABC+ groups (mean reduction 47% versus 41%; P = 0.72). Successful quitters had more years in education and had smoked less across their lifetime, but these differences were not statistically significant. CONCLUSION Smoking cessation in RA may lead to a reduced comorbid burden. The lack of added benefit of the tailored intervention suggests that brief advice and NRT are currently the best practice for supporting people with RA who wish to quit smoking.

Osteoporos Int 2016; 27:3239-3249. [PMID: 27273113 DOI: 10.1007/s00198-016-3646-z] [Citation(s) in RCA: 65] [Impact Index Per Article: 8.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/13/2016] [Accepted: 05/19/2016] [Indexed: 01/30/2023]
Abstract
UNLABELLED Retrospective claims analysis indicated that high levels of daily and cumulative doses of systemic glucocorticoids were associated with elevated fracture risk in a large cohort of new RA patients under age 65. Heightened risk began to decline within months of discontinuation. Findings were similar among patients age <50 years. INTRODUCTION We evaluated the impact of systemic glucocorticoid exposure on fracture risk among relatively young patients with new-onset rheumatoid arthritis (RA). METHODS Using administrative data, we identified 42,127 RA patients diagnosed January 1, 2005-December 31, 2012, age 18-64 years, with benefits coverage for ≥12 months before RA diagnosis. Follow-up extended to clinical fracture, cancer diagnosis, or December 31, 2012. Glucocorticoid users were new to therapy. Fracture incidence rates (IR) were stratified by glucocorticoid exposure expressed as prednisone equivalent doses. Cox's proportional hazards models estimated fracture risk adjusted for demographics and baseline clinical characteristics to assess dose-response relationships with current (daily) and prior (cumulative) dose, and by time since discontinuation. RESULTS Most patients (85 %) had glucocorticoid exposure. Exposed and unexposed patients were demographically similar (74 % female; mean age 49.7 and 48.8 years); 1 % had prior fracture. Fracture IRs (95 % confidence intervals) were 5 to 9 per 1000 person-years at doses <15 mg/day, 16.0 (11.0, 22.6) at doses ≥15 mg/day, and 13.4 (10.7, 16.7) at cumulative doses ≥5400 mg. Adjusted fracture risk was approximately 2-fold higher at highest dose levels compared with 0 mg/day current daily dose and <675 mg cumulative dose, respectively. Fracture risk was 29 % lower at 60-182 days post-discontinuation compared with ongoing use and was similar to unexposed patients by 12 months. Findings were similar among patients age <50 years. CONCLUSIONS Among younger, new-onset RA patients, fracture risk was significantly elevated at high levels of daily and cumulative dose, and was similar to unexposed patients by 12 months post-discontinuation.

Abstract
BACKGROUND AND OBJECTIVES Pemphigus vulgaris (PV) is typically treated with systemic corticosteroids and immunosuppressive agents. Avascular necrosis (AVN) of the femoral head is a well-recognized major complication of corticosteroid therapy. The characteristics of this serious complication in PV remain unknown. PATIENTS AND METHODS Uncontrolled, retrospective study of all PV-related AVN cases diagnosed at an Iranian autoimmune bullous disease clinic between 1985 and 2013. RESULTS Of the 2,321 medical records of PV patients reviewed, 45 (1.93 %) cases showed femoral AVN, with 30 (66.7 %) individuals being male. The mean age at diagnosis of AVN was 47.4 ± 14.2 years. The mean interval between the diagnosis of PV and the onset of AVN was 25.3 ± 18.3 months. With the exception of eight cases (17.8 %), the majority of patients developed AVN within three years after the diagnosis of PV. The mean cumulative dose of prednisolone in patients with AVN was 13,115.8 ± 7041.1 mg. There was a strong correlation between the total prednisolone dose and the time of onset of AVN (p = 0.001). In patients with a history of alendronate intake, that interval was significantly shorter (p = 0.01). CONCLUSIONS Occurring in about 2 % of patients, AVN is a serious complication of corticosteroid treatment in patients with PV, predominantly in the first three years of treatment. In individuals receiving higher doses of prednisolone, AVN tends to occur earlier.

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
Glucocorticoid-induced postmenopausal osteoporosis is a severe osteoporosis, with high risk of major osteoporotic fractures. This severe osteoporosis urges more extensive and deeper basic study, in which suitable animal models are indispensable. However, no relevant review is available introducing this model systematically. Based on the recent studies on GI-PMOP, this brief review introduces the GI-PMOP animal model in terms of its establishment, evaluation of bone mass and discuss its molecular mechanism. Rat, rabbit and sheep with their respective merits were chosen. Both direct and indirect evaluation of bone mass help to understand the bone metabolism under different intervention. The crucial signaling pathways, miRNAs, osteogenic- or adipogenic- related factors and estrogen level may be the predominant contributors to the development of glucocorticoid-induced postmenopausal osteoporosis.

Abstract
Glucocorticoids (GCs) were discovered in the 1940s and were administered for the first time to patients with rheumatoid arthritis in 1948. However, side effects were subsequently reported. In the last 7 decades, the mechanisms of action for both therapeutic properties and side effects have been elucidated. Mechanisms for minimizing side effects were also developed. GCs are the most frequently used class of drugs in the treatment of rheumatoid arthritis because of their efficacy in relieving symptoms and their low cost. A review of clinical applications, side effects, and drug interactions is presented.

Abstract
Background Bone loss during glucocorticoid (GC) therapy is poorly quantified. Objective Quantification of bone loss in GC-treated patients with chronic inflammatory diseases (CID; low dose) and transplants (high dose). Methods Meta-analysis of cohorts: PubMed, Cochrane, EMBASE and bibliographic searches (1995–2012). Eligible studies prospectively included GC-treated patients with two dual X-ray absorptiometry measurements of spine or hip over a period of at least 12 months. Only supplementation with calcium or vitamin D3 was allowed. 5602 titles yielded 285 articles: 51 study arms in CID (N=1565), 18 study arms in transplantation (N=571). Prednisone-equivalent GC doses and inverse variance weighted mean bone changes were used in a random effects model. Results In CID, the mean GC dose was 8.7 mg/day (range 1.2–16.4). The mean 1-year bone loss in the lumbar spine was −1.7% (95% CI –2.2% to –1.2%); in the femoral neck: –1.3 (–1.8 to –0.7). In transplantation, the mean GC dose was 18.9 mg/day (range 6.0–52.7). Bone loss in the lumbar spine was −3.6% (–5.2% to –2.0%); in the femoral neck: –3.1% (–5.1% to –1.1%). Within the two groups, bone loss was not related to GC dose. Conclusion In CID, GC-related bone loss appears limited and manageable if current anti-osteoporotic strategies are fully implemented. In transplantation, and probably also other high-dose settings, bone loss is considerable and represents unmet need. The heterogeneity probably reflects the important influence of other factors, most notably the underlying disease and the efficacy of GC treatment.

Diagnosis of polymyalgia rheumatica (PMR) and giant cell arteritis (GCA) is based on typical clinical, histologic, and laboratory features. Ultrasonographic imaging in PMR with assessment especially of subdeltoid bursitis can aid in diagnosis and in following response to treatment. In GCA, diagnosis and disease activity are supported with ultrasonographic, MRI, or [(18)F]fluorodeoxyglucose PET evaluation of large vessels. Glucocorticoids are the primary therapy for PMR and GCA. Methotrexate may be used in patients at high risk for glucocorticoid adverse effects and patients with frequent relapse or needing protracted therapy. Other therapeutic approaches including interleukin 6 antagonists are under evaluation.

Abstract
Among the interstitial lung diseases (ILDs), idiopathic pulmonary fibrosis (IPF), chronic hypersensitivity pneumonitis, and fibrotic connective tissue disease-related ILD are associated with a worse prognosis, with death occurring as a result of both respiratory failure and serious associated comorbidities. The recent development and approval of the antifibrotic agents nintedanib and pirfenidone, both of which reduced the rate of decline in lung function in patients with IPF in clinical trials, offer hope that it may be possible to alter the increased mortality associated with IPF. Although chronic hypersensitivity pneumonitis and connective tissue disease related-ILD may be associated with an inflammatory component, the evidence for the use of immunosuppressive agents in their treatment is largely limited to retrospective studies. The lack of benefit of immunosuppressive therapy in advanced fibrosis argues for rigorous clinical trials using antifibrotic therapies in these types of ILD as well. Patients with fibrotic ILD may benefit from identification and management of associated comorbid conditions such as pulmonary hypertension, gastroesophageal reflux, and OSA, which may improve the quality of life and, in some cases, survival in affected individuals. Because early assessment may optimize posttransplantation outcomes, lung transplant evaluation should occur early in patients with IPF and those with other forms of fibrotic ILD.

Influence of bisphosphonate therapy on bone geometry, volumetric bone density and bone strength of femoral shaft in postmenopausal women with rheumatoid arthritis. BMC Musculoskelet Disord 2016; 17:324. [PMID: 27491286 PMCID: PMC4974719 DOI: 10.1186/s12891-016-1167-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2016] [Accepted: 07/12/2016] [Indexed: 01/22/2023] Open
Abstract
BACKGROUND There is evidence that postmenopausal women with rheumatoid arthritis (RA) on glucocorticoid (GC) therapy and bisphosphonate (BP) have an increased risk for atypical subtrochanteric and atypical diaphyseal femoral fracture (AFF). The underlying mechanism has not been elucidated so far. Using peripheral quantitative computed tomography (pQCT), the aim of the present study was to compare bone geometry, volumetric bone mineral density (vBMD) and bone strength of femoral shaft in BP-treated and BP-naïve postmenopausal women with RA. METHODS Prospective cross-sectional pQCT scans were taken at 33 % of total femur of BP-treated and BP-naïve RA patients. Bone parameters of the two groups were compared and correlated to disease characteristics and muscle cross-sectional area (CSA). RESULTS A total of 60 consecutive postmenopausal RA patients, 20 with BP therapy and 40 BP-naïve, were included in the study. The median age of the subjects was 63.5 years (range 48-85 years), and median disease duration (RA) was 12.0 years (range 2-47 years). Height and weight of the patients of the two groups were comparable. Women in the BP group were on average 4.3 years older (p = 0.044), and duration since menopause was on average 5.76 years longer (p = 0.045). In the BP group, there was a 13.31 % reduced muscle cross-sectional area around the proximal thigh (p = 0.013); cortical CSA was smaller by 5.3 % (p = 0.043); however, total and medullary CSA, as well as cortical vBMD and the polar bone stress-strain index of the femoral shaft were similar in the two groups. In regression analysis, age, time since menopause and muscular CSA were significant factors determining cortical CSA, cortical thickness and femoral index (p < 0.05). Regression model showed no significant effect of BP therapy on bone geometry and density of the femoral diaphysis at 33 %. CONCLUSION Differences in cortical CSA between BP-treated and BP-naïve postmenopausal RA patients were found to be associated only with differences in age, time since menopause and muscle cross-sectional area around the proximal thigh. In interpreting our results, it should be kept in mind that BP was given only to patients with increased fracture risk. This fact might have a confounding effect on our findings of differences between the two groups.

Abstract
BACKGROUND Cutaneous lupus erythematosus (CLE) is an autoimmune disease, often exacerbated by sun exposure. Patients are encouraged to avoid sun exposure, therefore predisposing them to vitamin D deficiency. AIM To investigate the prevalence of and risk factors for vitamin D deficiency in patients with CLE. METHODS Total serum 25-hydroxy vitamin D (25(OH)D) was measured in 87 consecutive patients with CLE and in 79 controls. Clinical characteristics, disease severity, medications used and lifestyle factors were analysed and compared to determine risk factors for inadequate (25(OH)D), defined as a serum (25(OH)D) level of < 20 μg/L. RESULTS We found that 51% (n = 44) of the patients with CLE had 25(OH)D levels of < 20 μg/L compared with 73% (n = 58) of the controls (P < 0.01). No significant differences in (25(OH)D) levels were found between cases and controls with regard to age, sex, ethnicity, smoking, sun exposure, sunblock use or vitamin D supplementation. Treatment with antimalarials showed a statistically significant association with lower vitamin D levels. CONCLUSION Low levels of vitamin D were found in both patients with CLE and controls. Despite being on vitamin D supplementation and living in an equatorial location, our Asian patients with CLE still had low levels of vitamin D. It is therefore important to ensure adequate vitamin D supplementation in patients with CLE, especially for those who are on antimalarial therapy.

Abstract
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.

Abstract
As the population ages, the rates of osteoporotic fractures will increase, with postmenopausal women incurring most of these fractures. Diagnosis and treatment of osteoporosis are extremely important. Dual-energy x-ray absorptiometry scan screening is recommended in all women more than 65 years of age or in women aged 50 to 64 years with certain risk factors. Treatment should be considered if osteoporosis is present, there is a history of fragility fracture, or in the setting of osteopenia plus high risk for fracture.

Abstract
Objective To quantify the burden of osteoporosis and examine the interplay between osteoporosis and various comorbidities as it relates to patient outcomes. 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.

Abstract
Skin thickening is one of the early organ manifestations of systemic sclerosis (SSc) and has a great impact on quality of life (QOL) as well as overall daily living in patients with SSc. The dynamic changes that occur as the disease progresses and as other organs become further involved present the treating physician with therapeutic challenges. Hence, when considering drug therapy for skin disease, the treating physician should consider a number of factors including disease duration, the rate of skin thickening, the extent of disease progression, organ involvements, and patient-related outcome measures, all of which impact the type of treatments considered. For early diffuse skin disease, we prefer the use of methotrexate (MTX). And when there is evidence of lung involvement or tendon friction rubs (given its association with ILD development), we tend to shift to the use of mycophenolate or cyclophosphamide because these agents have been shown efficacious for the specific indication of lung disease in SSc. We have managed joint disease, on the other hand when present, with MTX or other DMARDs, as well as the use of biologics when there is evidence of inflammatory polyarthritis or rheumatoid arthritis overlap. While the treatment of myositis in the setting of SSc can present a therapeutic dilemma, reluctantly, we may use steroids along with MTX, mycophenolate, intravenous immunoglobulin (IV-Ig), or rituximab. Ongoing clinical trials investigating the use of tocilizumab, abatacept, and other agents offer promising potential therapies. Great strides have been made in treating skin disease in SSc. And with recent trials focusing on early SSc disease, this will allow for a greater insight into the mechanisms underlying SSc especially as it relates to skin, and the expansion of future treatment options in this field.

Abstract
PURPOSE The effect of bisphosphonates on extra-osseous tissue is rarely investigated. We performed an exploratory analysis on the association of new bisphosphonate use and incident tendon rupture in patients with or without oral glucocorticoid co-medication. METHODS We conducted a matched case-control study using data from the UK-based Clinical Practice Research Datalink. Cases were patients aged 30-89 years with an incident diagnosis of Achilles or biceps tendon rupture between 1995 and 2013. We compared new oral bisphosphonate use between cases and controls with or without oral glucocorticoid co-medication, by timing (last prescription </≥180 days) and duration (number of prescriptions) of bisphosphonate use. In a case-crossover analysis, we compared new bisphosphonate exposure in the event period and the control period controlling for glucocorticoid use. RESULTS Among 7859 cases, 246 (3.1%) were new users of bisphosphonates. Patients with glucocorticoid co-medication had an odds ratio (OR) for tendon rupture of 6.42 (95%CI 4.03-10.22) for short-term bisphosphonate use (≤4 prescriptions), which declined with increasing number of prescriptions. Among people with continuous prednisone use of 5-10 mg/day, bisphosphonate users with <9 prescriptions had an OR of 2.46 (95%CI 1.00-6.03), compared with bisphosphonate non-users. The case-crossover analysis yielded an OR of 4.46 (95%CI 2.76-7.20) for new bisphosphonate treatment in patients with glucocorticoid co-medication, and a null result in glucocorticoid non-users. CONCLUSIONS New bisphosphonate treatment may transiently increase the risk of tendon rupture in oral glucocorticoid users. Further research is needed to establish causality of this yet unreported adverse drug reaction or drug-drug interaction. Copyright © 2016 John Wiley & Sons, Ltd.

Abstract
Systemic lupus erythematosus (SLE) is a rare, severe, multisystem autoimmune disorder. Childhood-onset SLE (cSLE) follows a more aggressive course with greater associated morbidity and mortality than adult-onset SLE. Its aetiology is yet to be fully elucidated. It is recognised to be the archetypal systemic autoimmune disease, arising from a complex interaction between the innate and adaptive immune systems. Its complexity is reflected by the fact that there has been only one new drug licensed for use in SLE in the last 50 years. However, biologic agents that specifically target aspects of the immune system are emerging. Immunosuppression remains the cornerstone of medical management, with glucocorticoids still playing a leading role. Treatment choices are led by disease severity. Immunosuppressants, including azathioprine and methotrexate, are used in mild to moderate manifestations. Mycophenolate mofetil is widely used for lupus nephritis. Cyclophosphamide remains the first-line treatment for patients with severe organ disease. No biologic therapies have yet been approved for cSLE, although they are being used increasingly as part of routine care of patients with severe lupus nephritis or with neurological and/or haematological involvement. Drugs influencing B cell survival, including belimumab and rituximab, are currently undergoing clinical trials in cSLE. Hydroxychloroquine is indicated for disease manifestations of all severities and can be used as monotherapy in mild disease. However, the management of cSLE is hampered by the lack of a robust evidence base. To date, it has been principally guided by best-practice guidelines, retrospective case series and adapted adult protocols. In this pharmacological review, we provide an overview of current practice for the management of cSLE, together with recent advances in new therapies, including biologic agents.

Abstract
BACKGROUND Rheumatoid arthritis (RA) and inflammatory bowel disease (IBD) patient populations face similar risks of chronic immunosuppression including corticosteroid use. We compared the receipt of preventive services between IBD and RA populations according to published quality metrics. METHODS We defined a single-center cohort of patients with IBD or RA receiving specialty and primary care. Electronic health record abstraction assessed quality metrics, sociodemographics, comorbidity, and utilization. Comparisons used multivariate odds ratios and Student's t-tests. RESULTS 218 RA and 190 IBD patients were included. In multivariate analysis, IBD patients were less likely to receive pneumococcal vaccination (OR=0.29, 95% CI: 0.11-0.85), while RA patients underwent glucocorticoid-induced osteoporosis screening more often (100% vs. 82.5%, p = 0.023). CONCLUSIONS Gastroenterologists can improve care quality for IBD patients by assuming greater responsibility for preventive care in IBD patients and/or collaborating with primary care and health systems to improve preventive care delivery.

Abstract
UNLABELLED Efficacy of osteoporosis medication is not well-established among patients taking oral glucocorticoids. We assessed the efficacy of approved osteoporosis pharmacotherapies in preventing fracture by combining data from randomized controlled trials. Teriparatide, risedronate, and etidronate were associated with decreased vertebral fracture risk. INTRODUCTION Several osteoporosis drugs are approved for the prevention and treatment of glucocorticoid (GC)-induced osteoporosis. However, the efficacy of these treatments among oral GC users is still limited. We aimed to examine the comparative efficacy of osteoporosis treatments among oral GC users. METHODS We updated a systematic review through to March 2015 to identify all double-blinded randomized controlled trials (RCTs) that examined osteoporosis treatment among oral GC users. We used a network meta-analysis with informative priors to derive comparative risk ratios (RRs) and 95 % credible intervals (95 % CrI) for vertebral and non-vertebral fracture and mean differences in lumbar spine (LS) and femoral neck (FN) bone mineral density (BMD). Treatment ranking was estimated using the surface under the cumulative ranking curve (SUCRA) statistic. A meta-regression was completed to assess a subgroup effect between patients with prior GC exposures and GC initiators. RESULTS We identified 27 eligible RCTs examining nine active comparators. Etidronate (RR, 0.41; 95%CrI = 0.17-0.90), risedronate (RR = 0.30, 95%CrI = 0.14-0.61), and teriparatide (RR = 0.07, 95%CrI = 0.001-0.48) showed greater efficacy than placebo in preventing vertebral fractures; yet, no treatment effects were statistically significant in reducing non-vertebral fractures. Alendronate, risedronate, and etidronate increased LS BMD while alendronate and raloxifene increased FN BMD. In preventing vertebral fractures, teriparatide was ranked as the best treatment (SUCRA: 77 %), followed by risedronate (77 %) and zoledronic acid (76 %). For non-vertebral fractures, teriparatide also had the highest SUCRA (69 %), followed by risedronate (64 %). No subgroup effect was identified with regards to prior GC exposure. CONCLUSIONS Despite weak trial evidence available for fracture prevention among GC users, we identified several drugs that are likely to prevent osteoporotic fracture. Teriparatide, risedronate, and etidronate were associated with decreased vertebral fracture risk.

Abstract
INTRODUCTION The understanding of the etio-pathogenesis of autoimmune encephalopathy syndromes has grown significantly in recent years. These are potentially reversible conditions, with variable clinical presentation and potential dramatic response to immunotherapy. AREAS COVERED In this article we review various diagnostic techniques and therapeutic options for management of autoimmune encephalopathy. We also review medication adverse effects and monitoring strategies. Expert commentary: Early diagnosis and immunomodulatory treatment remains the cornerstone of management, to halt the underlying neuro-inflammatory process and prevent permanent neuronal injury. The availability of serological testing and various imaging modalities has further improved detection of these immune-mediated neurological disorders. Understanding the mechanisms and potential adverse effects of immunomodulatory therapies will help physicians to choose the most favorable therapeutic strategy for each patient.

Abstract
Extracts from plastrum testudinis (PTE), an important traditional Chinese medicine, have been demonstrated promotion of osteoblastic function in vitro. This study aims to investigate the protective effect of PTE on glucocorticoid-induced osteoporosis(GIOP) in vivo and analyze therapeutic targets of PTE on GIOP. SD rats were randomly assigned to two experiments: preventive and therapeutic experiments, in which rats respectively received oral PTE at the same time of glucocorticoid injection or after glucocorticoid injection inducing osteoporosis. BMD, microarchitecture, biomechanics, bone metabolism markers and histomorphology were evaluated. mRNA and protein expression of OPG, Runx2, CTSK and MMP9 were examined.Results showed bone quality and bone quantity were significantly elevated by PTE. Histomorphometry showed thicker and denser bone trabecularsand more osteoblasts and less osteoclasts in group of PTE intervention. The mRNA expression of OPG was significantly upregulated whereas expression of CTSK was significantly downregulatedin different groups of PTE intervention. Stronger immunostaining for Runx2 and weaker immunostaining for CTSK were observed in groups of PTE intervention. This demonstrated that PTE may reverse GIOP in prevention and management via targeting OPG, Runx2 and CTSK in mRNA and protein levels.

Fracture risk in oral glucocorticoid users: a Bayesian meta-regression leveraging control arms of osteoporosis clinical trials. Osteoporos Int 2016; 27:1709-18.

Abstract
UNLABELLED Little data exist on the frequency of fracture among oral glucocorticoid users. We examined the effect of oral glucocorticoids on fracture incidence using data from randomized controlled trials. Patients starting glucocorticoids had a higher probability of fracture and decline in bone mineral density compared to chronic glucocorticoid users. INTRODUCTION Oral glucocorticoids (GCs) are the leading cause of secondary osteoporosis. However, there have been few studies that quantify the rate of fracture among GC users. We sought to provide a pooled estimate of fracture risk from randomized controlled trials (RCTs) of GC-treated patients. METHODS We updated a MEDLINE search published by the American College of Rheumatology through to March 2015 and identified RCTs of osteoporosis therapies that reported fracture and bone mineral density (BMD) among oral GC users. We restricted the analysis to placebo or control arms. RCT arms were stratified by GC exposure at enrolment to GC initiators (≤6 months) and chronic GC users (>6 months). Bayesian meta-regression was used to estimate the annual probability of vertebral fracture (primary), non-vertebral fracture and percentage change in lumbar spine and femoral neck BMD. RESULTS The annual incidence of vertebral and non-vertebral fracture was 5.1 % (95 % CrI = 2.8-8.2) and 2.5 % (95 % CrI = 1.2--4.2) among GC initiators, and 3.2 % (95 % CrI = 1.8-5.0) and 3.0 % (95 % CrI = 0.8-5.9) among chronic GC users. Our meta-regression identified a non-significant effect of group-level variables (mean age, mean BMD, mean GC daily dose, patients with previous vertebral fractures, proportion of women and adjuvant used) on vertebral fracture rate. CONCLUSION Our study found higher vertebral fracture incidence among GC initiators, yet a relative decline in fracture incidence with longer exposure. Our findings suggest that fracture incidence among oral GC users may be more common than previously estimated. Optimizing GC-induced osteoporosis management during early exposure to GC is essential to prevent fractures.

Abstract
Systemic lupus erythematosus (abbreviated SLE or lupus) is a systemic autoimmune disease, with genetic, immunologic, hormonal, and environmental factors. 1 One of the environmental factors that has been studied over the years is vitamin D, which is created in the human body in response to exposure to sunlight and ultraviolet (UV) radiation. This review aims at examining findings from recent years, specifically 2013–2014, regarding the relationship between vitamin D deficiency and SLE flares, severity, and clinical manifestation, as well as to examine the treatment options derived from this relationship.

Abstract
Trabecular bone score (TBS) is a gray-level textural index of bone microarchitecture derived from lumbar spine dual-energy X-ray absorptiometry (DXA) images. TBS is a bone mineral density (BMD)-independent predictor of fracture risk. The objective of this meta-analysis was to determine whether TBS predicted fracture risk independently of FRAX probability and to examine their combined performance by adjusting the FRAX probability for TBS. We utilized individual-level data from 17,809 men and women in 14 prospective population-based cohorts. Baseline evaluation included TBS and the FRAX risk variables, and outcomes during follow-up (mean 6.7 years) comprised major osteoporotic fractures. The association between TBS, FRAX probabilities, and the risk of fracture was examined using an extension of the Poisson regression model in each cohort and for each sex and expressed as the gradient of risk (GR; hazard ratio per 1 SD change in risk variable in direction of increased risk). FRAX probabilities were adjusted for TBS using an adjustment factor derived from an independent cohort (the Manitoba Bone Density Cohort). Overall, the GR of TBS for major osteoporotic fracture was 1.44 (95% confidence interval [CI] 1.35-1.53) when adjusted for age and time since baseline and was similar in men and women (p > 0.10). When additionally adjusted for FRAX 10-year probability of major osteoporotic fracture, TBS remained a significant, independent predictor for fracture (GR = 1.32, 95% CI 1.24-1.41). The adjustment of FRAX probability for TBS resulted in a small increase in the GR (1.76, 95% CI 1.65-1.87 versus 1.70, 95% CI 1.60-1.81). A smaller change in GR for hip fracture was observed (FRAX hip fracture probability GR 2.25 vs. 2.22). TBS is a significant predictor of fracture risk independently of FRAX. The findings support the use of TBS as a potential adjustment for FRAX probability, though the impact of the adjustment remains to be determined in the context of clinical assessment guidelines. © 2015 American Society for Bone and Mineral Research.

Abstract
BACKGROUND It remains uncertain whether kidney transplant recipients are a high-risk group for fracture. METHODS We conducted a cohort study using Ontario, Canada health care databases to estimate the 3-, 5- and 10-year cumulative incidence of nonvertebral fracture (proximal humerus, forearm, hip) in adult kidney transplant recipients between 1994 and 2009, stratifying by sex and age (<50 versus ≥50 years) at transplant. We also assessed the 3-year cumulative incidence of all fracture locations (excluding skull, toes, and fingers) and falls, 10-year cumulative incidence of hip fracture alone, and nonvertebral fracture incidence in recipients compared to nontransplant reference groups matched on age, sex, and cohort entry year. We studied 4821 recipients (median age, 50 years). RESULTS Among the age and sex strata, female recipients aged 50 years or older had the highest 3-year cumulative incidence of nonvertebral fracture (3.1%; 95% confidence interval [95% CI], 2.1-4.4%). Recipients had a higher 3-year cumulative incidence of nonvertebral fracture (1.6%; 95% CI, 1.3-2.0%) compared to the general population with no previous nonvertebral fracture (0.5%; 95% CI, 0.4-0.6%; P < 0.0001) and nondialysis chronic kidney disease (1.1%; 95% CI, 0.9-1.2%; P = 0.03), but a lower fracture incidence than the general population with a previous nonvertebral fracture (2.3%; 95% CI, 1.9-2.8%; P = 0.007). The 10-year cumulative incidence of hip fracture in all recipients was 1.7% (≥3% defined as high risk in clinical guidelines). CONCLUSIONS Kidney transplant recipients may have a lower fracture risk than previously suggested in the literature. Results inform our understanding of fracture incidence after kidney transplantation and how it compares to nontransplant populations.

Abstract
OBJECTIVE To report and analyze quality improvement (QI) efforts that are aimed at increasing adherence to preventive guidelines for glucocorticoid-induced osteoporosis (GIOP). METHODS We performed a PubMed literature search for full-length articles in English between 1966 and 2013, describing approaches for improving the quality of GIOP care. We reviewed articles using a structured approach and abstracted information on the patient population, study design, QI intervention, and primary outcome measures. A descriptive analysis was then performed. RESULTS Literature search identified 661 articles; 38 were screened by abstract, 10 were identified for full review, and 7 were included. Two non-randomized, uncontrolled studies of system changes showed significant improvements in GIOP prevention: one increased concomitant prescriptions of glucocorticoids and calcium (37-49%, p < 0.0001) and vitamin D (38-53%, p < 0.0001) using a computerized order entry system; another used a dedicated clinical team to increase vitamin D levels from 19.5 to 29.4 (p = 0.001) and improve GIOP-related habits. Five articles described education-based interventions, including 3 randomized controlled trials (RCTs). Two non-significant RCTs focused on physicians, but one directed towards pharmacists and patients did increase calcium supplementation in the intervention vs. control arm (55.7% vs. 31.6%, p < 0.05). Two other non-randomized educational interventions did not show benefits. Comparison of articles was limited by the heterogeneity of the intervention methods and outcome measures used. CONCLUSION None of the interventions produced robust changes, with overall adherence to GIOP guidelines remaining low. System-based interventions appeared more effective than education-based interventions, but a diverse array of factors likely needs to be addressed, requiring more randomized controlled trials and greater standardization of outcome measures.

Abstract
The prevention and treatment of osteoporosis is an increasingly important topic in the solid organ transplant (SOT) population. Compared to the general population, these patients are at an elevated risk of developing osteoporosis due to progressive disease, lifelong immunosuppressant therapy, and malnutrition. As patients live longer after transplant, chronic disease management is increasingly more important. Supplementation with calcium and vitamin D is often necessary in the SOT population due to a high incidence of vitamin D deficiency. Bisphosphonate therapy is most commonly used for prevention and treatment of osteoporosis, but therapy can be limited by renal dysfunction which is common in transplant recipients. Alternative agents such as teriparatide and calcitonin have not been shown to provide a significant impact on the rate of fractures in this population. Additionally, denosumab may be a promising treatment option due to its novel mechanism of action, and is currently being studied in renal transplant patients. Timely initiation of supplementation and treatment, and minimizing glucocorticoid exposure prior to and after transplantation will aid in the prevention and proper management of osteoporosis in these patients.

Abstract
Dual-energy X-ray absorptiometry (DXA) is a technology that is widely used to diagnose osteoporosis, assess fracture risk, and monitor changes in bone mineral density (BMD). The clinical utility of DXA is highly dependent on the quality of the scan acquisition, analysis, and interpretation. Clinicians are best equipped to manage patients when BMD measurements are correct and interpretation follows well-established standards. Poor-quality acquisition, analysis, or interpretation of DXA data may mislead referring clinicians, resulting in unnecessary diagnostic evaluations, failure to evaluate when needed, inappropriate treatment, or failure to provide medical treatment, with potentially ineffective, harmful, or costly consequences. Misallocation of limited healthcare resources and poor treatment decisions can be minimized, and patient care optimized, through meticulous attention to DXA instrument calibration, data acquisition and analysis, interpretation, and reporting. This document from the International Society for Clinical Densitometry describes quality standards for BMD testing at DXA facilities worldwide to provide guidance for DXA supervisors, technologists, interpreters, and clinicians. High-quality DXA testing is necessary for correct diagnostic classification and optimal fracture risk assessment, and is essential for BMD monitoring.

Abstract
We investigated the relationship between dermatomyositis/polymyositis (DM/PM) and the risk of subsequent osteoporosis development. A population-based retrospective cohort analysis was conducted using the National Health Insurance Research Database and the Catastrophic Illness Patients Database of Taiwan. We included 1179 patients and 4716 patients from 1999 to 2008 as the DM/PM cohort and the comparison cohort, respectively, and calculated the incidence rates of newly diagnosed osteoporosis. We used Cox proportional hazards models stratified on matched pair to assess the effect of DM/PM. The Kaplan-Meier method was applied to estimate the cumulative osteoporosis incidence curves. Patients with DM/PM were 2.99 times more likely to experience osteoporosis than those without DM/PM. The risk for osteoporosis in DM/PM patients was higher than comparisons in different propensity score quartiles. DM/PM cohort, no matter treated with or without corticosteroids and immunosuppressant, had a higher risk than the comparison cohort. The incidence of osteoporosis in Taiwan is associated with a priori DM/PM history. This risk was independent of the corticosteroids and immunosuppressant treatment.

Efficacy and safety of minodronic acid hydrate in patients with steroid-induced osteoporosis. Int J Rheum Dis 2016; 21:813-820.

Abstract
OBJECTIVES Minodronic acid hydrate, an oral bisphosphonate, has a greater inhibitory effect on bone resorption than do other approved drugs; however, this has been studied only in patients with primary osteoporosis. Here, we administered minodronic acid hydrate to patients with steroid-induced osteoporosis who have been treated with steroids for rheumatoid arthritis or other collagen diseases, and the efficacy and safety of minodronic acid hydrate were prospectively investigated. METHODS Twenty-five patients treated in our rheumatology clinic received minodronic acid hydrate 1 mg/day. The changes in bone mineral density (BMD) and bone turnover markers were investigated at 3 and 6 months, and adverse events, including the presence or absence of an incident osteoporotic fracture, were examined over a period of 6 months. RESULTS Percent changes in BMD of the lumbar spine and femur significantly increased. The values of bone turnover markers significantly decreased. There were no patients with a radiographically apparent incident fracture. Adverse events included toothache for which the patient discontinued the treatment and three cases of gastrointestinal disorder that did not lead to discontinuation, and thus minodronic acid hydrate was well tolerated. CONCLUSIONS Here, we show that minodronic acid hydrate is effectively and safely used for treatment of steroid-induced osteoporosis.

Abstract
Rheumatoid arthritis (RA) is expected to increase in Africa and South Africa. Due to the low numbers of rheumatologists in South Africa, specialist physicians also have to care for patients with RA. Furthermore several new developments have taken place in recent years which improved the management and outcome of RA. Classification criteria were updated, assessment follow-up tools were refined and above all, several new biological disease-modifying anti-rheumatic drugs were developed. Therefore it is imperative for specialist physicians to update themselves with the newest developments in the management of RA. This article provides an overview of the newest developments in the management of RA in the South African context. This approach may well apply to countries with similar specialist to patient ratios and disease profiles.
