Huang CC, Hung CC, Chen HM, Lin JW, Fu SH, Wang CY. Real world clinical outcomes when discontinuing denosumab or bisphosphonates in patients with surgically managed osteoporotic vertebral compression fractures: a population-based cohort study. Spine J 2024:S1529-9430(24)00942-2. [PMID: 39154948 DOI: 10.1016/j.spinee.2024.08.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2024] [Revised: 07/05/2024] [Accepted: 08/09/2024] [Indexed: 08/20/2024]
Abstract
BACKGROUND CONTEXT Osteoporotic vertebral compression fractures (OVCFs) are common fragility fractures. Patients who undergo surgical treatment for their initial OVCFs warrant particular attention because there is an elevated risk of subsequent vertebral fractures and other types of fragility fractures. However, the optimal osteoporosis treatment for this specific patient group is less investigated. PURPOSE This study compares the risk of subsequent osteoporotic fractures and mortality rate for patients who are initiated with denosumab and bisphosphonates and determines the effect of adherence to treatment. STUDY DESIGN Retrospective nationwide cohort study PATIENT SAMPLE: A total of 2,858 patients who had surgically-managed osteoporotic vertebral compression fractures. OUTCOME MEASURES The risk of osteoporotic fractures, vertebral fractures, nonvertebral fractures and death. METHODS This is a retrospective nationwide cohort study that uses the National Health Insurance Research Database. Patients aged ≥50 years who were admitted for surgical interventions for OVCF between 2012 and 2016 and subsequently received denosumab or bisphosphonates for one year were included. Patients were stratified according to their antiosteoporosis medications and adherence to treatment. A multivariable, time-varying Cox proportional hazards model was used to determine the risk of osteoporotic fractures, vertebral fractures, nonvertebral fractures and death. RESULTS A total of 2,858 patients were included in this study: 1,123 patients in the denosumab group and 1,735 patients in the bisphosphonates group. Compared to persistent denosumab users, the nonpersistent denosumab users, persistent bisphosphonate users and nonpersistent bisphosphonate users had a greater risk of osteoporotic fractures, with respective hazard ratios of 1.64 (95% confidence interval [CI], 1.16-2.32), 1.74 (95% CI, 1.25-2.42) and 1.53 (95% CI, 1.14-2.06). If osteoporotic fractures were divided into nonvertebral and vertebral fractures, none of the groups exhibited an increased risk of vertebral fractures compared to persistent denosumab users, with an HR of 1.00 (95% CI: 0.54-1.88) for nonpersistent denosumab users, 1.64 (95% CI: 0.96-2.81) for persistent bisphosphonate users and 1.52 (95% CI: 0.95-2.43) for nonpersistent bisphosphonate users. However, there was a significantly greater risk of nonvertebral fracture, with respective hazard ratios of 2.04 (95% CI, 1.33-3.11), 1.80 (95% CI, 1.18-2.76) and 1.56 (95% CI, 1.06-2.27) for nonpersistent denosumab users, persistent bisphosphonate users and nonpersistent users. Noteworthy, nonpersistent denosumab users exhibited a significantly greater risk of mortality than persistent denosumab users, with a hazard ratio of 3.12 (95% CI, 2.22-4.38). CONCLUSIONS In terms of patients with OVCFs who require hospitalization and surgical intervention, those who receive ongoing denosumab treatment exhibit less risk of developing subsequent osteoporotic fractures than those who receive bisphosphonates or nonpersistent denosumab treatment. However, discontinuation of denosumab is associated with a significantly increased risk of subsequent fractures and mortality. Therefore, adherence to the treatment is crucial for patients who are initiated with denosumab.

[PMID: 39114369 PMCID: PMC11303733 DOI: 10.3389/fmolb.2024.1390257] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2024] [Accepted: 05/15/2024] [Indexed: 08/10/2024] Open
Abstract
To alleviate bone loss, most current drugs target osteoclasts. Saikosaponin A (Ssa), a triterpene saponin derived from Bupleurum falcatum (also known as Radix bupleuri), has immunoregulatory, neuromodulatory, antiviral, anticancer, anti-convulsant, anti-inflammatory, and anti-proliferative effects. Recently, modulation of bone homeostasis was shown to involve ferroptosis. Herein, we aimed to determine Ssa's inhibitory effects on osteoclastogenesis and differentiation, whether ferroptosis is involved, and the underlying mechanisms. Tartrate-resistant acid phosphatase (TRAP) staining, F-actin staining, and pit formation assays were conducted to confirm Ssa-mediated inhibition of RANKL-induced osteoclastogenesis in vitro. Ssa could promote osteoclast ferroptosis and increase mitochondrial damage by promoting lipid peroxidation, as measured by iron quantification, FerroOrange staining, Dichloro-dihydro-fluorescein diacetate, MitoSOX, malondialdehyde, glutathione, and boron-dipyrromethene 581/591 C11 assays. Pathway analysis showed that Ssa can promote osteoclasts ferroptosis by inhibiting the Nrf2/SCL7A11/GPX4 axis. Notably, we found that the ferroptosis inhibitor ferrostatin-1 and the Nrf2 activator tert-Butylhydroquinone reversed the inhibitory effects of Ssa on RANKL-induced osteoclastogenesis. In vivo, micro-computed tomography, hematoxylin and eosin staining, TRAP staining, enzyme-linked immunosorbent assays, and immunofluorescence confirmed that in rats with periodontitis induced by lipopolysaccharide, treatment with Ssa reduced alveolar bone resorption dose-dependently. The results suggested Ssa as a promising drug to treat osteolytic diseases.

Abstract
Despite the increasing efforts in improving bone health assessments, current diagnostics suffer from critical shortcomings. The present article therefore describes a multiplex label-free immunosensor designed and validated for the assessment of two bone turnover markers (BTMs), namely beta isomerized C-terminal telopeptide of type I collagen (CTx) and Procollagen I Intact N-Terminal (PINP), the combination of which is needed to illustrate an accurate overview of bone health. The immunosensor was then tested outside and inside of a microsystem, with the aim of becoming compatible with a point of care system fabricated for automated assessment of these biomarkers later-on at patient side. Custom-made monoclonal antibodies were specifically designed for this purpose in order to guarantee the selectivity of the immunosensor. In the final platform, a finger prick blood sample is introduced into the microfluidic manifolds without any need for sample preparation step, making the tool suitable for near patient and outside of the central laboratory applications. The platform was exploited in 30 real blood samples with the results validated using electrochemiluminescence immunoassay. The results revealed the platform was capable of measuring the target analyte with high sensitivity and beyond the recommended clinical reference range for each biomarker (CTx: 104-1028 ng L-1 and PINP: 16-96 μg L-1, correspondingly). They also showed the platform to have a limit of detection of 15 (ng L-1) and 0.66 (μg L-1), a limit of quantification of 49 (ng L-1) and 2.21 (μg L-1), and an inter- and intra-assay coefficient of variance of 5.39-6.97% and 6.81-5.37%, for CTx and PINP respectively, which is comparable with the gold standard. The main advantage of the platform over the state-of-the art was the capability of providing the results for two markers recommended for assessing bone health within 15 minutes and without the need for skilled personnel or costly infrastructure.

Analyzing the factors associated with efficacy among teriparatide treatment in postmenopausal women with osteoporosis. BMC Musculoskelet Disord 2024; 25:109. [PMID: 38310278 PMCID: PMC10837964 DOI: 10.1186/s12891-024-07227-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Accepted: 01/23/2024] [Indexed: 02/05/2024] Open
Abstract
BACKGROUND Teriparatide (TPTD) is a widely used anabolic agent for the treatment of osteoporosis. Several factors have been identified to be related to bone mineral density (BMD) increase in anti-osteoporosis treatment with other agents; however, there has been no systematic analysis to summarize the associated determinants of BMD reaction to daily teriparatide treatment. METHODS In this retrospective study, we performed a comprehensive investigation involving not only clinical data but also several relevant lifestyle factors to be examined for their potential contribution to BMD response. This post-hoc analysis included 258 post-menopaused patients with osteoporosis who received TPTD at 20 µg/day for 12 months. Univariate and multivariate analyses were conducted to distinguish the response variables of lumbar spine (LS) BMD transformation, the principal outcome measure of efficacy, from the baseline at 12 months. RESULTS Twelve months of TPTD treatment resulted in an absolute 0.39 ± 0.37 increase in T-score of LS BMD. Gastrointestinal disease, prior bisphosphonate or glucocorticoid treatment, no vitamin K2 supplementation, low levels of serum 25(OH)D and PINP, weak increment of PINP and β-CTX at 3 months, unhealthy lifestyle (excessive smoking, tea, coffee, and drinking), vegetarian diet pattern, low ALT level, and high BMD at baseline were determined by univariate analyses to be related to the weak reaction of TPTD treatment (P < 0.10). In the multiple regression model, postmenopausal women with vitamin K2 supplementation, higher baseline serum 25(OH)D level, and higher PINP concentration at 3 months indicated a good reaction of LS BMD at 12 months (P < 0.05). Patients with gastrointestinal disease, prior bisphosphonate and glucocorticoid treatment, vegetarian diet pattern, and higher baseline BMD were significantly more likely to have a lower absolute LS BMD response compared to patients without these characteristics (P < 0.05). Further analysis confirmed the negative effect of unhealthy lifestyle on TPTD treatment. CONCLUSION Our results emphasize the significance of a comprehensive assessment of clinical or lifestyle-related characteristics of postmenopausal women with osteoporosis in the management of TPTD therapy in routine care.

Nocebo-associated treatment discontinuation with subcutaneous anti-osteoporotic drugs. A systematic review and meta-analysis of placebo-arm dropouts in randomized-controlled trials. Maturitas 2024; 179:107874. [PMID: 37976923 DOI: 10.1016/j.maturitas.2023.107874] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Revised: 09/22/2023] [Accepted: 10/24/2023] [Indexed: 11/19/2023]
Abstract
OBJECTIVE Nocebo is a concept of therapeutics referring to unpleasant symptoms attributed by a patient to a drug, due to negative anticipation. Patients receiving oral anti-osteoporotic drugs in randomized controlled trials (RCT) can experience adverse events leading to dropout, implying that nocebo contributes to treatment discontinuation for these drugs. In this study we aim to investigate the nocebo effect of subcutaneous anti-osteoporotic drugs with a higher compliance rate than orally administered drugs. STUDY DESIGN We searched MEDLINE, EMBASE, SCOPUS, and Cochrane databases for double-blind trials investigating subcutaneous anti-osteoporotic drugs for osteoporosis (namely, denosumab, teriparatide, abaloparatide and romosozumab) published up to May 2023. MAIN OUTCOME MEASURE Dropouts due to reported adverse events in the placebo arms ("nocebo dropouts"). RESULTS Data from 17 trials were extracted. Among 10,529 placebo-treated patients the pooled nocebo-dropout percentage was 3 % for denosumab (average: 0.03; 95 % CI: 0.01-0.05), 1 % for romosozumab (average: 0.01; 95 % CI: 0.00-0.03) and 6 % for teriparatide and abaloparatide (average: 0.06; 95 % CI: 0.05-0.07). Nocebo-dropouts were significantly higher in men than women (6 % vs. 3 %, respectively, p = 0.012), in older (mean age >68 years) than in younger patients (5 % vs. 1 %, respectively, p = 0.017) and in those with more severe osteoporosis (based on the percentage of participants with prior fragility-related fractures in the study cohort) compared with patients with no prior fracture history (4 % vs. 1 %, respectively, p = 0.046). CONCLUSION Nocebo responses may contribute to treatment discontinuation with subcutaneous anti-osteoporotic drugs in clinical practice. Higher nocebo-related dropout rates in the higher-risk RCT population (older patients, males, those with prior fractures) show that nocebo mechanisms have the potential to hinder therapeutic efforts to specific populations who would benefit most.

Abstract
BACKGROUND Long-term care issues, specifically metabolic bone disorders, are a concern for people living with human immunodeficiency virus (PLWH) who undergo life-long antiretroviral therapy (ART). Previous clinical trials with denosumab, an anti-RANKL antibody inhibitor, have revealed its effectiveness in increasing bone mineral density (BMD) in patients with osteoporosis. However, there are limited data on adherence and effectiveness of denosumab treatment for osteoporosis in PLWH. Hence, this study aimed to investigate the adherence and effectiveness of denosumab treatment for osteoporosis in Japanese PLWH. METHODS This study is a retrospective exploratory analysis of 29 Japanese PLWH who initiated denosumab treatment for osteoporosis, between 2013 and 2021. The study included patients who received at least one dose of denosumab every 6 months. Adherence and persistence were defined as receiving two consecutive injections of denosumab 6 months ± 4 weeks apart and 6 months + 8 weeks apart, respectively. The primary outcome measure of the study was the adherence of denosumab treatment for 24 months. The secondary outcome measures included treatment persistence and BMD. The period after January 2020 was defined as the coronavirus disease 2019 (COVID-19) pandemic period, and its impact on adherence was investigated. RESULTS The treatment adherence rates at 12 and 24 months were 89.7% and 60.7%, respectively. By contrast, the treatment persistence at 12 and 24 months was 100% and 85.7%, respectively. More patients in the group who initiated denosumab treatment after the COVID-19 pandemic reached non-adherence than in the group who initiated denosumab treatment before the pandemic. BMD at the lumbar spine and femoral neck significantly increased compared to that at baseline, with median percentage changes of 8.7% (p < 0.001) and 3.5% (p = 0.001), respectively. CONCLUSIONS The results showed that patients in the study had a high rate of non-adherence but a lower rate of non-persistence. Additionally, PLWH on ongoing ART experienced increased BMD with denosumab treatment. This study provides an opportunity to improve future strategies for denosumab treatment in the Japanese PLWH.

Abstract
INTRODUCTION Stroke prevention using oral anticoagulation (OAC) is the first management priority in atrial fibrillation (AF). Despite the importance of good therapy adherence, real-world adherence is still suboptimal. Patient education and adherence monitoring with new technologies are recommended. The main purpose of this sub-analysis of the AF-EduCare trial was to evaluate the effect of personalized follow-up strategies on adherence to OAC. METHODS Regimen adherence was monitored by the electronic Medication Event Monitoring System cap at the start of the trial (M1) and after 12 months (M2), each for three months. Patients were part of one of three education groups (In-person, Online or App-based) or the standard care (SC) group. All are qualified for OAC therapy. RESULTS A total of 768 patients were evaluated (11.8% SC vs. 86.8% any education group, mean age: 70.1 ± 7.9 years). Patients were taking non-vitamin K OAC (once daily 53.8%; twice daily 35.9%) or vitamin K antagonists (9.4%), equally distributed over the different study arms (p = 0.457). Mean therapy adherence was high (M1:93.8 ± 10.8%; M2:94.1 ± 10.1%). During both monitoring periods, the education group scored significantly higher than SC (M1:94.2 ± 10.0% vs. 91.3 ± 15.0%; p = 0.027; M2:94.4 ± 9.3% vs. 91.6 ± 14.0%; p = 0.006). More patients in the In-person and Online groups were able to keep or improve their adherence to > 90% compared to the SC. CONCLUSION Overall adherence to OAC in all study groups, even in SC, was very high, without attrition over time. Nevertheless, targeted education led to a small but significantly improved adherence compared to SC.

Persistence with Denosumab in Male Osteoporosis Patients: A Real-World, Non-Interventional Multicenter Study. Endocrinol Metab (Seoul) 2023; 38:260-268. [PMID: 37150519 PMCID: PMC10164495 DOI: 10.3803/enm.2023.1663] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Accepted: 03/06/2023] [Indexed: 05/09/2023] Open
Abstract
BACKGRUOUND Persistence with denosumab in male patients has not been adequately investigated, although poor denosumab persistence is associated with a significant risk of rebound vertebral fractures. METHODS We retrospectively evaluated 294 Korean male osteoporosis patients treated with denosumab at three medical centers and examined their persistence with four doses of denosumab injection over 24 months of treatment. Persistence was defined as the extent to which a patient adhered to denosumab treatment in terms of the prescribed interval and dose, with a permissible gap of 8 weeks. For patients who missed their scheduled treatment appointment(s) during the follow-up period (i.e., no-shows), Cox proportional regression analysis was conducted to explore the factors associated with poor adherence. Several factors were considered, such as age, prior anti-osteoporotic drug use, the treatment provider's medical specialty, the proximity to the medical center, and financial burdens of treatment. RESULTS Out of 294 male patients, 77 (26.2%) completed all four sequential rounds of the denosumab treatment. Out of 217 patients who did not complete the denosumab treatment, 138 (63.6%) missed the scheduled treatment(s). Missing treatment was significantly associated with age (odds ratio [OR], 1.03), prior bisphosphonate use (OR, 0.76), and prescription by non-endocrinologists (OR, 2.24). Denosumab was stopped in 44 (20.3%) patients due to medical errors, in 24 (11.1%) patients due to a T-score improvement over -2.5, and in five (2.3%) patients due to expected dental procedures. CONCLUSION Our study showed that only one-fourth of Korean male osteoporosis patients were fully adherent to 24 months of denosumab treatment.

Abstract
Osteoporosis is the most common systemic skeletal disease worldwide. Its consequences have a substantial impact on the quality of life of patients and increases the overall morbidity and mortality. Standardized diagnostic procedures and treatment recommendations have been available for years as German and international (S3) guidelines. Nevertheless, there is a considerable gap in the diagnosis and adequate treatment of osteoporosis, especially in Germany. The aim is to detect the disease at an early stage and to establish a specific and consistent treatment of osteoporosis. In this way the quality of life and independence of those affected can be maintained over a long period. In the acute and permanent treatment of manifest osteoporosis, surgeons, orthopedic and trauma surgeons play a key role.

Abstract
OBJECTIVE Periprosthetic bone mineral density (BMD) loss after total hip arthroplasty (THA) may threaten the survival of implants. Zoledronic acid (ZA) and denosumab were effective in reducing bone loss in conditions associated with accelerated bone turnover by inhibiting osteoclast activity. This meta-analysis aimed to assess the efficiency and safety of ZA and denosumab for periprosthetic BMD loss after THA. METHODS A systematic search of randomized controlled trials (RCTs) associated with ZA or denosumab and THA was performed in MEDLINE, PubMed, Embase, the Cochrane Central Register of Controlled Trials, and the Web of Science from 1980 to 2022. Meta-analysis was performed by the Cochrane Review Manager 5 (RevMan) version 5.41. Cochrane risk of bias tool and GRADEpro were applied for methodological quality and overall evidence quality, respectively. RESULTS Nine RCTs involving a total of 480 patients were finally included and analyzed. The pooled data that demonstrated significantly less periprosthetic BMD loss in Gruen zone 7 occurred in the intervention group patients than in the control group patients at 3 months (MD = 4.30, 95% CI: 1.78-6.82, P = 0.0008), 6 months (MD = 7.71, 95% CI: 5.41-10.02, P < 0.00001), and 12 months (MD = 8.19, 95% CI: 5.97-10.42, P < 0.00001) after THA. No serious adverse events (AEs) were observed. CONCLUSION In the current analysis with evidence on the efficacy and safety of ZA and denosumab, the authors recommend the use of ZA or denosumab treatment for periprosthetic bone mineral density loss.

Abstract
A primary osteoporosis prevention program using a virtual bone health team (BHT) was implemented to comanage the care of rural veterans in the Mountain West region of the United States. The BHT identified, screened, and treated rural veterans at risk for osteoporosis using telephone and United States Postal Service communications. Eligibility was determined by regular use of Veterans Health Administration primary care, age 50 or older, and evidence of fracture risk. This study was conducted to identify demographic and clinical factors associated with the acceptance of osteoporosis screening and the initiation of medication where indicated. A cross-sectional cohort design (N = 6985) was utilized with a generalized estimating equation and logit link function to account for facility-level clustering. Fully saturated and reduced models were fitted using backward selection. Less than a quarter of eligible veterans enrolled in BHT's program and completed screening. Factors associated with a lower likelihood of clinic enrollment included being of older age, unmarried, greater distance from VHA services, having a copayment, prior fracture, or history of rheumatoid arthritis. A majority of veterans with treatment indication started medication therapy (N = 453). In this subpopulation, Fisher's exact test showed a significant association between osteoporosis treatment uptake and a history of two or more falls in the prior year, self-reported parental history of fracture, current smoking, and weight-bearing exercise. The BHT was designed to reduce barriers to screening; however, for this population cost and travel continue to limit engagement. The remarkable rate of medication initiation notwithstanding, low enrollment reduces the impact of this primary prevention program, and findings pertaining to fracture, smoking, and exercise imply that health beliefs are an important contributing factor. Efforts to identify and address barriers to osteoporosis screening and treatment, such as clinical factors, social determinants of health, and health beliefs, may pave the way for effective implementation of population bone health care delivery systems.

Abstract
Background/Aim: Denosumab is a human monoclonal antibody that binds to the receptor-activated nuclear factor kappa beta ligand (RANKL). Densosumab leads to a reduction in bone resorption by inhibiting RANKL and has been approved for treating postmenopausal osteoporosis (OP). The present study investigated real life data by evaluating the demographic data of postmenopausal patients with OP who received denosumab treatment and the changes in dual energy x-ray absorptiometry (DEXA) parameters before and after denosumab treatment.
Methods: This retrospective cohort study included 49 postmenopausal female patients followed in our OP outpatient clinic who were treated with 60 mg subcutaneous denosumab every six months for at least 12 months. The study retrospectively analyzed and recorded patient age, body mass index, age of menopause, fracture history, antiresorptive and/or anabolic drug treatment history, and pre- and post-denosumab T-scores in addition to L1–4, femoral neck, and total hip bone mineral densities (BMDs) on DEXA scans. The changes that occurred before and after the treatment in addition to those that occurred after the treatment based on whether previous anabolic or antiresorptive agents had been used were statistically compared.
Results: The L1–4 and total hip T-scores and L1–4 and total hip BMD values measured prior to denosumab treatment showed a statistically significant increase after denosumab treatment (P < 0.001, P = 0.002, P = 0.028, and P = 0.002, respectively). No statistically significant changes in the femoral neck T-score and BMD after denosumab treatment compared to that before denosumab use (P = 0.056 and P = 0.138, respectively) were found. Furthermore, no statistically significant difference between the pre- and post-denosumab DEXA parameters in the patients who used antiresorptive agents and those who did not (P > 0.05) was found. Additionally, pre- and post-denosumab parameters were not statistically significantly different between those who received and did not receive anabolic therapy before denosumab (P > 0.05).
Conclusion: Denosumab treatment for postmenopausal OP leads to a significant increase in lumbar and total hip T-scores and BMDs.

Abstract
Treatment persistence was higher among the patients who initially received an anti-osteoporosis medication (AOM) with a long-dose-interval. PURPOSE With long-dose-interval anti-osteoporosis medications (AOMs) available for osteoporosis management, it is important to evaluate persistence of any AOM as long as it is continuously used. The purpose of this study was to investigate the treatment pattern and persistence of AOMs, allowing for medication switch. METHODS This study was an observational retrospective cohort study using Taiwan's National Health Insurance claims data. We selected patients who first initiated an AOM between January 1, 2013, and June 30, 2016. AOM therapy included alendronate, raloxifene, teriparatide, denosumab, zoledronate, and ibandronate; the latter three were categorized as long-dose-interval medications. Persistence was defined as continual prescription of any AOM at a given time point with a grace period of 45 days within which to obtain prescription refill. The competing risk model was used to examine the factors affecting patients switching their initial AOM. RESULTS During the study period, 126,539 patients with mean age of 75 years met the inclusion criteria; 85% were female. For initial AOM, 43.3%, 25.6%, 14.6%, 9.3%, 5.3%, and 1.9% of the patients received alendronate, denosumab, raloxifene, zoledronate, ibandronate, and teriparatide, respectively. During a mean 36-month follow-up, 29.6% of the patients who received at least two AOM pharmacy claims throughout the study period have ever switched their initial medication. Long-dose-interval medications, mainly denosumab and zoledronate, were the preferred choice for medication switch. Treatment persistence was higher in patients who initiated with long-dose-interval AOMs. CONCLUSION The real-world data reveal long-dose-interval therapy as an initial treatment or at the first switch stage may improve management of persistent AOM treatment.

Abstract
OBJECTIVES Persistence with treatment is key to achieving successful treatment outcomes in patients with osteoporosis. We investigated risk factors for denosumab discontinuation in patients with postmenopausal osteoporosis (PMO). METHODS A total of 333 patients with PMO who had never received osteoporosis treatment were included in this study. Baseline demographics and retention rate of denosumab were evaluated in all patients. Univariate analysis was performed in patients divided into two groups according to whether they had continued or discontinued denosumab. A Cox proportional hazards model was used to determine risk factors for denosumab discontinuation. RESULTS Mean age was 80.7 years, body mass index (BMI) was 21.5 kg/m2, and T-scores for the lumbar spine and femoral neck were -2.7 and -2.8, respectively. The retention rate of denosumab at 36 months was 50.3%. Patients who continued denosumab were younger and had higher BMI, serum albumin (Alb) levels, and lumbar spine bone mineral density, and fewer vertebral fractures (VFs), compared with those who discontinued denosumab. The Cox proportional hazards model revealed that a low BMI, low serum Alb levels, and a high number of VFs are independent risk factors for denosumab discontinuation. CONCLUSIONS A low BMI, low serum Alb levels, and a high number of VFs were associated with denosumab discontinuation in patients with PMO.

Abstract
BACKGROUND Depression, osteoporosis, and cardiovascular disease impose a heavy economic burden on society. Understanding economic impacts of suboptimal use of medication due to nonadherence and non-persistence (non-MAP) for these conditions is important for clinical practice and health policy-making. OBJECTIVE This systematic literature review aims to assess the impact of non-MAP to antidepressants, bisphosphonates and statins on healthcare resource utilisation and healthcare cost (HRUHC), and to assess how these impacts differ across medication classes. METHODS A systematic literature review and an aggregate meta-analysis were performed. Using the search protocol developed, PubMed, Cochrane Library, ClinicalTrials.gov, JSTOR and EconLit were searched for articles that explored the relationship between non-MAP and HRUHC (i.e., use of hospital, visit to healthcare service providers other than hospital, and healthcare cost components including medical cost and pharmacy cost) published from November 2004 to April 2021. Inverse-variance meta-analysis was used to assess the relationship between non-MAP and HRUHC when reported for at least two different populations. RESULTS Screening 1,123 articles left 10, seven and 13 articles on antidepressants, bisphosphonates, and statins, respectively. Of those, 27 were rated of good quality, three fair and none poor using the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. In general, non-MAP was positively associated with HRUHC for all three medication classes and most prominently for bisphosphonates, although the relationships differed across HRUHC components and medication classes. The meta-analysis found that non-MAP was associated with increased hospital cost (26%, p = 0.02), outpatient cost (10%, p = 0.01), and total medical cost excluding pharmacy cost (12%, p<0.00001) for antidepressants, and increased total healthcare cost (3%, p = 0.07) for bisphosphonates. CONCLUSIONS This systematic literature review is the first to compare the impact of non-MAP on HRUHC across medications for three prevalent conditions, depression, osteoporosis and cardiovascular disease. Positive relationships between non-MAP and HRUHC highlight inefficiencies within the healthcare system related to non-MAP, suggesting a need to reduce non-MAP in a cost-effective way.

Abstract
Osteoporosis is the most common systemic skeletal disease worldwide. Its consequences have a substantial impact on the quality of life of patients and increases the overall morbidity and mortality. Standardized diagnostic procedures and treatment recommendations have been available for years as German and international (S3) guidelines. Nevertheless, there is a considerable gap in the diagnosis and adequate treatment of osteoporosis, especially in Germany. The aim is to detect the disease at an early stage and to establish a specific and consistent treatment of osteoporosis. In this way the quality of life and independence of those affected can be maintained over a long period. In the acute and permanent treatment of manifest osteoporosis, surgeons, orthopedic and trauma surgeons play a key role.

Abstract
BACKGROUND Adherence to medication regimens is of great importance in psychiatry because drugs sometimes need to be taken for long durations in order to maintain health and function. OBJECTIVE To review influences on adherence to antipsychotic medications, the treatment of choice for delusional disorder (DD), and to focus on adherence in women with DD. METHOD A non-systematic narrative review of papers published since 2000 using PubMed and Google Scholar and focusing on women with DD and medication adherence. RESULTS Several factors have been identified as exerting influence on adherence in women with persistent delusional symptoms who are treated with antipsychotics. Personality features, intensity of delusion, perception of adverse effects, and cognitive impairment are patient factors. Clinical time spent with the patient, clarity of communication and regular drug monitoring are responsibilities of the health provider. Factors that neither patient nor clinician can control are the social determinants of health such as poverty, easy access to healthcare, and cultural variables. CONCLUSIONS There has been little investigation into factors that influence adherence in the target population discussed here -e.g. women with DD. Preliminary results of this literature search indicate that solutions from outside the field of DD may apply to this population. Overall, a solid therapeutic alliance appears to be the best hedge against non-adherence.

Abstract
Denosumab is approved for osteoporosis treatment in subjects with and without chronic kidney disease (CKD). Confirmation is required for its safety, treatment adherence, renal function effect, and mortality in patients with CKD. A retrospective cohort study was conducted to compare new users of denosumab in terms of their two-year drug adherence in all participants (overall cohort) and CKD participants (CKD subcohort), which was defined as baseline estimated glomerular filtration rate (eGFR) less than 60 mL/min/1.73 m2. The eGFR was calculated using the 2021 CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) equation. We defined high adherence (HA) users as receiving three or four doses and low adherence (LA) users as receiving one or two doses. All-cause mortality was analyzed using Kaplan-Meier curves and Cox regression models. In total, there were 1142 subjects in the overall cohort and 500 subjects in the CKD subcohort. HA users had better renal function status at baseline than LD users in the overall cohort. A decline in renal function was only observed among LD users in the overall cohort. In the CKD subcohort, no baseline renal function difference or renal function decline was demonstrated. The all-cause mortality rate of HA users was lower than LA users in both the overall cohort and CKD. A randomized control trial is warranted to target this unique population to confirm our observations.

Abstract
To investigate the suppressive function of RO4929097, a potent -secretase inhibitor, on RANKL-induced osteoclastogenesis. The cytotoxicity of RO4929097 was evaluated. The suppressive effect and possible molecular mechanism of RO4929097 on RANKL-induced osteoclastogenesis was evaluated both in vitro and in vivo. The IC50 of RO4929097 was 2.93 μM. Treatment with different doses of RO4929097 (100 nM, 200 nM, and 400 nM) effectively reduced osteoclast formation (number and resorption area) in a dose-dependent manner. The qPCR results revealed that RO4929097 attenuates RANKL-induced osteoclast formation and NFATc1 protein expression. The in vivo experiments demonstrated that RO4929097 had an inhibitory effect on LPS-induced bone resorption. Our in vitro experiments showed that RO4929097 can potently inhibit osteoclastogenesis and bone resorption by down-regulating the Notch/MAPK/JNK/Akt-mediated reduction of NFATc1. In accordance with these in vitro observations, RO4929097 attenuated LPS-induced osteolysis in mice. In conclusion, our findings indicate that Notch may represent a potential therapeutic target for the treatment of osteolytic diseases.

Abstract
PURPOSE To assess the 12 and 24-month persistence with denosumab in postmenopausal women with osteoporosis in real-world clinical practice in France, and to describe characteristics and management of these patients. METHODS This prospective, multicenter cohort study evaluated persistence with denosumab at 12 months (primary endpoint) and 24 months (secondary endpoint), defined as at least 2 or 4 injections respectively, and time elapsed between 2 consecutive injections did not exceed 6 months +8 weeks. Other endpoints included patients' characteristics at baseline, medical history, concomitant and previous treatments, and incidence of adverse drug reactions (ADR), serious adverse events and fractures. RESULTS 478 patients were enrolled by 86 physicians between June 2015 and February 2016. The mean follow-up was 28 months. Mean age was 72 years and 91% of patients had been previously treated for osteoporosis. The persistence with denosumab was 86% (95%CI: 83%-89%) at 12 months and 72% (95%CI: 68%-76%) at 24 months. Using the Kaplan-Meier estimates, the persistence probability over time was 86% at 12 months and 76% at 24 months. During the study, 78 patients discontinued therapy. No multiple vertebral fractures were reported upon discontinuation. ADR were reported for 55 patients, 4 being serious, and 27 patients discontinued denosumab due to an ADR. Among patients who received at least one injection, 10 died. None of the deaths were attributable to denosumab. CONCLUSION Persistence with denosumab at 12 and 24 months was high, and the treatment was well tolerated among postmenopausal women with osteoporosis treated in routine clinical practice in France.

Abstract
The role of anti-osteoporotic treatment as part of the secondary prevention after hip fracture in terms of mortality and re-fracture risk has been studied, and the results are promising. Decreased treatment adherence and compliance is a problem that needs to be addressed by healthcare professionals. A systematic review of the literature was performed using the PubMed database with terms that included hip fracture, mortality, second fracture, and specific anti-osteoporotic treatment. We included 28 articles, 21 regarding mortality and 20 re-fracture rates in hip fracture patients. All studies showed lower mortality after hip fracture associated with anti-osteoporotic treatment, mostly bisphosphonate agents. The re-fracture risk is still debatable, since conflicting data were found. Although most of the studies showed notable effects on mortality and re-fracture rates associated with anti-osteoporotic treatment, we still need more data to validate the actual results.

Abstract
INTRODUCTION Post-menopausal women with osteoporosis > 70 years of age at high risk of fracture urgently require treatment for fracture prevention. Moreover, persistence with osteoporosis therapy is critical for real-world effectiveness. We estimated persistence with denosumab in older women at high fracture risk in clinical practice in Bulgaria. METHODS Eligible participants were post-menopausal women, > 70 years of age, diagnosed with osteoporosis (T-score ≤ - 2.5) and at high risk of fracture (≥ 3% for hip and ≥ 20% for major osteoporotic fracture) who received at least one denosumab injection before enrollment. Planned follow-up was 24 months. The primary endpoint was persistence to denosumab at 12, 18, and 24 months (defined as receiving all denosumab injections within 6 months ± 60 days of the previous injection). RESULTS 250 women were enrolled across 12 Bulgarian endocrinology/rheumatology practices; median follow up, 736 days. Mean (SD) age was 75.8 (4.2) years; mean (SD) FRAX® was 13.1 (8.6) for hip and 26.1 (9.5) for major osteoporotic fracture; 47 (18.8%) women had prior osteoporosis therapy and 104 (41.6%) had prior fracture. Denosumab persistence was high: 98.0%, 92.4%, and 84.4% at 12, 18, and 24 months, respectively. A total of 42 (16.8%) women discontinued denosumab during follow-up, mostly for financial reasons [25/42 (59.5%)] or loss to follow-up [8/42 (19.0%)]. After 24 months of denosumab treatment, BMD T-score improvement to the range of osteopenia (- 2.5 ≤ T < - 1.5) was achieved by 42.4% at the femoral neck, 23.6% at the lumbar spine, and 49.2% at the total hip; complete recovery (T-score ≥ - 1.5) was observed in 9.0%, 26.4%, and 23.0% respectively. New fracture was reported in 5 patients (2%). CONCLUSIONS Even in an elderly population, persistence with denosumab was high despite the challenge imposed by the 50% co-pay in Bulgaria.

Abstract
PURPOSE Although denosumab is a safe and effective treatment for osteoporosis in various clinical trials, few studies have investigated its efficacy in specific clinical situations. The effect of non-compliance with the standard six-month dosing regimen for denosumab on bone mineral density (BMD) was assessed in a retrospective study of patients prescribed denosumab during the COVID-19 pandemic. PATIENTS AND METHODS Between February 2019 and September 2020, 638 patient records were reviewed, with 236 patients meeting the eligibility criteria. Patients were divided into three groups: those who received denosumab injections between five and seven months after their initial subcutaneous injection, those who received denosumab injections between seven and nine months after their initial subcutaneous injection, and those who received denosumab injections more than nine months after their initial subcutaneous injection. A multivariate regression study was conducted to compare the BMD shift (at least one year apart) before and after two denosumab injections between the three pre-specified groups in both the lumbar spine (LS) and the femoral neck (FN). RESULTS The difference between LS BMD indicates that there is a statistical difference between subjects who received denosumab injections between 5 and 7 months (near-standard dosing interval) and more than 9 months (P=0.03), but not in FN BMD, and no clinically significant association was identified. CONCLUSION The results of this study show that in special clinical situations, such as the COVID-19 pandemic, clinicians may have some flexibility to prescribe denosumab, but the interval between injections should not exceed 9 months.

Abstract
Background:
Poor adherence to the prescribed therapy leads to low bone mineral density
and enhance the development of osteoporosis complications and unnecessary hospitalization.
Objective:
To explore factors associated with medication non-adherence in patients with osteoporosis.
Findings would help guide the development of future pharmaceutical care interventions aim at
improving health outcomes for patients with osteoporosis.
Methods:
The study was conducted at an outpatient osteoporosis clinic at the Royal Medical Services
Hospital. Variables including socio-demographics and medical factors were collected using
medical records and custom-designed questionnaire. Medication adherence was assessed using the
validated 4-item Morisky Medication Adherence Scale. Logistic regression was performed to develop
a model with variables that best predicted medication non-adherence in patients with osteoporosis
in Jordan.
Results:
A total of 296 patients participated in the study. Most of the study participants (72.3%)
were found non-adherent. Patients were found less likely to adhere to the prescribed medications
with each unit increase in the number of prescribed medications (OR = 2.503, CI = 1.103-5.680)
and if they did not have a trust in the efficacy of the medications (OR = 5.544, CI = 0.990-31.058).
Conclusion:
Medication adherence for patients with osteoporosis has considered scope for improvement
in Jordan. Simplifying dosage regimen in addition to taking patients’ preferences when
selecting the medications should be taken into account in future interventions designed to improve
health outcomes for patients with osteoporosis.

Abstract
Osteoporosis is a chronic disease of low bone mass and fragility. Treatment is frequently compromised by suboptimal medication compliance causing increased morbidity. This review investigates adherence and persistence to parenteral osteoporosis therapies. Findings reveal parenteral medications requiring reduced dosing frequency have higher compliance than oral therapies. This systematic review examines real-world adherence to parenteral osteoporosis therapies. We searched PubMed, Medline, and EMBASE databases for English language observational studies that examined patient adherence and/or persistence to parenteral osteoporosis treatments (teriparatide sc, ibandronate iv, zoledronic acid iv, and denosumab sc) in adults with osteoporosis published up to September 2018. Studies with only self-reported adherence or persistence data and those with less than 20 patients were excluded. Quality assessment of included studies was completed using the Newcastle-Ottawa quality assessment scale (NOS). We identified 40 eligible studies. Teriparatide was examined in 29 studies, with persistence rates of 10-87% (median 55%) at 1 year and 10-69% (median 29.5%) at 2 years, and adherence rates of 21-89% (median 53%) at 1 year and 37-68% (median 40%) at 2 years. Ten studies of zoledronic acid reported persistence rates of 34-73% (median 42%) for second dose and 20-54% (median 35.8%) for third dose. Ten studies of ibandronate adherence reported and 2-year persistence rates of 31-58% (median 47.5%) in 1 year and 13-35% (median 25%) at 2 years, and adherence rates of 21-72% (median 47.3%) and 15-58% (median 36.5%) respectively. Denosumab was reported in 19 studies, with second (1 year) and fourth (2 year) dose persistence rates of 61-100% (median 81%) and 36-99% (median 45.5%). There is substantial heterogeneity in reports of persistence and adherence rates with parenteral osteoporosis therapies. Most of the published data are from short-term studies and evaluations of long-term adherence and persistence with parenteral therapies for osteoporosis are needed.

Abstract
BACKGROUND Denosumab is effective for osteoporosis, but discontinuation leads to rapid reversal of its therapeutic effect. OBJECTIVE To estimate the risk for fracture among users of denosumab who delayed subsequent doses compared with users who received doses on time. DESIGN Population-based cohort study. SETTING The Health Improvement Network U.K. primary care database, 2010 to 2019. PATIENTS Persons aged 45 years or older who initiated denosumab therapy for osteoporosis. MEASUREMENTS Observational data were used to emulate an analysis of a hypothetical trial with 3 dosing intervals: subsequent denosumab injection given within 4 weeks after the recommended date ("on time"), delay by 4 to 16 weeks ("short delay"), and delay by more than 16 weeks ("long delay"). The primary outcome was a composite of all fracture types at 6 months after the recommended date. Secondary outcomes were major osteoporotic fracture, vertebral fracture, hip fracture, and nonvertebral fracture. RESULTS Investigators identified 2594 patients initiating denosumab therapy. The risk for composite fracture over 6 months was 27.3 in 1000 for on-time dosing, 32.2 in 1000 for short delay, and 42.4 in 1000 for long delay. Compared with on-time injections, short delay had a hazard ratio (HR) for composite fracture of 1.03 (95% CI, 0.63 to 1.69) and long delay an HR of 1.44 (CI, 0.96 to 2.17) (P for trend = 0.093). For vertebral fractures, short delay had an HR of 1.48 (CI, 0.58 to 3.79) and long delay an HR of 3.91 (CI, 1.62 to 9.45). LIMITATION Dosing schedules were not randomly assigned. CONCLUSION Although delayed administration of subsequent denosumab doses by more than 16 weeks is associated with increased risk for vertebral fracture compared with on-time dosing, evidence is insufficient to conclude that fracture risk is increased at other anatomical sites with long delay.

Abstract
BACKGROUND Fragility fractures are fractures that result from mechanical forces that would not ordinarily result in fracture. OBJECTIVES The objectives were to evaluate the clinical effectiveness, safety and cost-effectiveness of non-bisphosphonates {denosumab [Prolia®; Amgen Inc., Thousand Oaks, CA, USA], raloxifene [Evista®; Daiichi Sankyo Company, Ltd, Tokyo, Japan], romosozumab [Evenity®; Union Chimique Belge (UCB) S.A. (Brussels, Belgium) and Amgen Inc.] and teriparatide [Forsteo®; Eli Lilly and Company, Indianapolis, IN, USA]}, compared with each other, bisphosphonates or no treatment, for the prevention of fragility fracture. DATA SOURCES For the clinical effectiveness review, nine electronic databases (including MEDLINE, EMBASE and the World Health Organization International Clinical Trials Registry Platform) were searched up to July 2018. REVIEW METHODS A systematic review and network meta-analysis of fracture and femoral neck bone mineral density were conducted. A review of published economic analyses was undertaken and a model previously used to evaluate bisphosphonates was adapted. Discrete event simulation was used to estimate lifetime costs and quality-adjusted life-years for a simulated cohort of patients with heterogeneous characteristics. This was done for each non-bisphosphonate treatment, a strategy of no treatment, and the five bisphosphonate treatments previously evaluated. The model was populated with effectiveness evidence from the systematic review and network meta-analysis. All other parameters were estimated from published sources. An NHS and Personal Social Services perspective was taken, and costs and benefits were discounted at 3.5% per annum. Fracture risk was estimated from patient characteristics using the QFracture® (QFracture-2012 open source revision 38, Clinrisk Ltd, Leeds, UK) and FRAX® (web version 3.9, University of Sheffield, Sheffield, UK) tools. The relationship between fracture risk and incremental net monetary benefit was estimated using non-parametric regression. A probabilistic sensitivity analysis and scenario analyses were used to assess uncertainty. RESULTS Fifty-two randomised controlled trials of non-bisphosphonates were included in the clinical effectiveness systematic review and an additional 51 randomised controlled trials of bisphosphonates were included in the network meta-analysis. All treatments had beneficial effects compared with placebo for vertebral, non-vertebral and hip fractures, with hazard ratios varying from 0.23 to 0.94, depending on treatment and fracture type. The effects on vertebral fractures and the percentage change in bone mineral density were statistically significant for all treatments. The rate of serious adverse events varied across trials (0-33%), with most between-group differences not being statistically significant for comparisons with placebo/no active treatment, non-bisphosphonates or bisphosphonates. The incremental cost-effectiveness ratios were > £20,000 per quality-adjusted life-year for all non-bisphosphonate interventions compared with no treatment across the range of QFracture and FRAX scores expected in the population eligible for fracture risk assessment. The incremental cost-effectiveness ratio for denosumab may fall below £30,000 per quality-adjusted life-year at very high levels of risk or for high-risk patients with specific characteristics. Raloxifene was dominated by no treatment (resulted in fewer quality-adjusted life-years) in most risk categories. LIMITATIONS The incremental cost-effectiveness ratios are uncertain for very high-risk patients. CONCLUSIONS Non-bisphosphonates are effective in preventing fragility fractures, but the incremental cost-effectiveness ratios are generally greater than the commonly applied threshold of £20,000-30,000 per quality-adjusted life-year.

Abstract
CONTEXT Discontinuation of denosumab leads to a rapid reversal of its therapeutic effect. However, there are no data regarding how unintended delays or missed injections of denosumab impact bone mineral density (BMD) response. OBJECTIVE We examined the association of delays in injections of denosumab with BMD change. DESIGN We used electronic medical records from two academic hospitals from 2010 to 2017. PARTICIPANTS Patients older than 45 years of age and used at least 2 doses of 60 mg denosumab. Denosumab adherence was evaluated by the medication coverage ratio (MCR). Good adherence corresponds to a dosing interval ≤7 months (defined by MCR ≥93%), moderate adherence corresponds to an interval of 7 to 10 months (MCR 75%-93%), and poor adherence corresponds to an interval ≥10 months (MCR ≤75%). OUTCOME MEASURES Annualized percent BMD change from baseline at the lumbar spine, total hip, and femoral neck. RESULTS We identified 938 denosumab injections among 151 patients; the mean (SD) age was 69 (10) years, and 95% were female. Patients with good adherence had an annualized BMD increase of 3.9% at the lumbar spine, compared with patients with moderate (3.0%) or poor adherence (1.4%, P for trend .002). Patients with good adherence had an annualized BMD increase of 2.1% at the total hip, compared with patients with moderate (1.3%) or poor adherence (0.6%, P for trend .002). CONCLUSIONS A longer interval between denosumab injections is associated with suboptimal BMD response at both spine and total hip. Strategies to improve the timely administration of denosumab in real-world settings are needed.

Osteoporos Int 2020; 31:765-774. [PMID: 31927612 DOI: 10.1007/s00198-020-05290-7] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/28/2019] [Accepted: 01/06/2020] [Indexed: 10/25/2022]
Abstract
UNLABELLED Significant dropout rates have been observed throughout Fracture Liaison Service (FLS) programs, especially for elderly patients. In an FLS program set up specifically for patients over 70, the non-initiation of osteoporosis treatment was the only factor associated with poor adherence to the program. Neither age nor frailty factors affected adherence. INTRODUCTION FLS programs are considered the most effective interventions for secondary prevention of osteoporotic fractures. Our objective was to identify risk factors for non-adherence to an FLS program set up specifically for patients over 70. METHODS Our multifaceted, intensive program included five appointments over a 2-year period. One hundred sixty-seven patients (mean age 83.5 years) who presented with a recent fragility fracture were enrolled. Multivariable analysis was conducted to determine whether the demographic, clinical, frailty, and osteoporotic risk factors of the patients influenced their adherence to the program. RESULTS About half of the patients did not attend the follow-up visits. According to the regression analysis, non-initiation of osteoporosis treatment was associated with poor adherence to the program (aHR 3.66). Demographic, clinical, dwelling, frailty factors, osteoporotic risk factors, fracture type, or densitometric scores were not associated with adherence. The first self-reported reason for withdrawal was the difficulty of attending several follow-up visits, and the second was the feeling of not being concerned. CONCLUSION We observed that non-initiation of osteoporosis treatment was the only factor correlated with non-adherence to an FLS program. Thus, neither age nor frailty factors should result in patients not being included in FLS. Beyond the necessity of the osteoporosis treatment, good patient understanding of the relevance of all the interventions included in the program is the key.

Abstract
UNLABELLED Gaining full benefits from osteoporosis medications requires long-term treatment. Investigating the real-world persistence of women receiving osteoporosis medications in the UK, we found that most patients stop treatment within a year. To prevent osteoporotic fragility fractures, long-term treatment persistence must be improved. INTRODUCTION Persistence with osteoporosis therapies has historically been poor. To treat this chronic and progressive disease, it is essential that patients receive the full benefit of these medications. We estimated persistence and compliance with osteoporosis therapies in a large sample of postmenopausal women in the UK. METHODS Data were obtained from the Clinical Practice Research Datalink for all women aged 50 years and over or women with early menopause, who received at least one prescription in primary care for any licensed osteoporosis therapy between January 1, 2010 and December 31, 2015. Persistence and compliance at 24 months (primary objective) and at 5 years (exploratory objective) were estimated in three patient cohorts: "All Patients," "Naïve Patients," and "Drug-Specific." RESULTS The All Patients cohort included 72,256 women. Persistence with any therapy was 56.1%, 43.6%, 36.4%, and 31.0% at 6, 12, 18, and 24 months, respectively, and 23.2% and 13.1% at 3 years and 5 years, respectively. Patients were generally more persistent and compliant if evaluated from their first exposure to osteoporosis therapy (Naïve Patients cohort). In the drug-specific analysis, 64% of patients receiving denosumab (administered subcutaneously every 6 months) were persistent at 24 months compared with 28% and 23% of those taking oral bisphosphonates and intravenous bisphosphonates, respectively. CONCLUSIONS Only about one in three patients who received osteoporosis therapy continued to be on treatment after 2 years. There is a need to improve persistence with osteoporosis therapy, especially for high-risk patients.

Abstract
Bone resorption, caused by osteoclasts (OCs), is important to bone homeostasis. The abnormalities of bone resorption may induce a series of diseases, including osteoarthritis, osteoporosis and aseptic peri-implant loosening. The latest research developed,a novel tyrosine and phosphoinositide kinase dual inhibitor, named PP121, inhibited Src in anaplastic thyroid carcinoma cell. However, the therapeutic function of PP121 on abnormal bone resorption is still uncertain. In the present study, we showed that PP121 could potently suppress osteoclast differentiation, osteoclast-specific gene expression and bone resorption via suppressing Src/MAPK (ERK and p38)/Akt-mediated NFATc1 induction in vitro. \It was found that PP121 could suppress the formation of osteoclasts from bone marrow macrophages (BMMs) without causing cytotoxicity, inhibit bone resorption and downregulate the mRNA level of osteoclast-specific markers, including calcitonin receptor (CTR), tartrate resistant acid phosphatase (TRAP), cathepsin K (CTSK), matrix metalloproteinase 3 (MMP3), Cellular oncogene fos (C-Fos) and nuclear factor of activated T-cells cytoplasmic 1 (NFATc1). Consistent with in vitro observation, we found that PP121 greatly ameliorated LPS-induced bone resorption. Our results provide promising evidence of the therapeutic potential of PP121 for osteolytic diseases related to excessive osteoclast-mediated bone resorption.

[PMID: 33122894 PMCID: PMC7588837 DOI: 10.2147/ppa.s266697] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2020] [Accepted: 09/21/2020] [Indexed: 01/22/2023] Open
Abstract
BACKGROUND Factors determining bisphosphonate compliance are not fully understood. We examined fluctuations in oral bisphosphonate dosing intervals to gauge therapeutic compliance in patients with osteoporosis. MATERIALS AND METHODS Hospital data accruing between 2010 and 2017 were accessed to retrospectively study patients ≥50 years old (N=1873), each prescribed bisphosphonate at initial diagnosis of osteoporosis. The medication possession ratio (MPR), calculated as total days supplied divided by length of follow-up, served to measure therapeutic compliance. We compared MPRs of various prescription patterns (daily, weekly, monthly, and switch [ie, ≥1 change in pattern] groups). We also analyzed the impact of age, sex, fracture history, surgical history, and comorbidities. Multiple regression analysis was ultimately performed, using MPR as a dependent variable. RESULTS In our cohort (mean follow-up=5.7±2.4 years), once weekly dosing was the most common prescription pattern (1223/1873, 65.3%), as opposed to monthly (366/1873, 19.5%) or daily (164/1873, 8.8%) dosing. A total of 120 patients (6.4%) comprising the switch group changed dosing patterns during the study period. MPR was significantly higher in the switch group (32.8±22.7) than in the other three groups (daily, 21.9±25.9; weekly, 22.7±27.3; monthly, 23.2±27.7). In multiple regression analysis, younger age (P<0.001), female sex (P=0.004), and switching of prescription pattern (decrease or increase frequency) were factors significantly associated with higher MPR, signaling better compliance. CONCLUSION Better bisphosphonate compliance was associated with physician-modified dosing patterns. We therefore recommend adjustments of prescription intervals in poorly compliant patients requiring long-term treatment.

Abstract
Numerous safe and efficient drug therapies are currently available to decrease risk of low trauma fractures in patients with osteoporosis including postmenopausal, male, and secondary osteoporosis. In this chapter, we give first an overview of the most important outcomes regarding fracture risk reduction, change in bone mineral density (BMD by DXA) and/or bone markers of the phase III clinical studies of well-established therapies (such as Bisphosphonates, Denosumab or Teriparatide) and also novel therapies (such as Romosozumab or Abaloparatide) and highlight their mechanisms of action at bone tissue/material level. The latter understanding is not only essential for the choice of drug, duration and discontinuation of treatment but also for the interpretation of the clinical outcomes (in particular of eventual changes in BMD) after drug administration. In the second part of this chapter, we focus on the management of different forms of osteoporosis and give a review of the respective current guidelines for treatment. Adverse effects of treatment such as atypical femoral fractures, osteonecrosis of the jaw or influence of fracture healing are considered also in this context.

Abstract
We examined differences in patients' survival after hip fracture (HF) and risk for subsequent HF among patients treated with oral and intravenous bisphosphonates (oBPs, iBPs), denosumab (DMAB), and patients without therapy. We used data from all patients in Austria aged ≥ 50 who sustained a HF between 2012 and 2017 and were followed for a subsequent HF and all-cause mortality until 2017. Antiosteoporotic treatment-naïve patients, who were incident users of BPs and DMAB, were eligible for propensity score matching 1:1 to obtain comparable user groups. We applied competing risk approach and calculated cumulative incidence functions and subdistribution-hazards for refracture. Cox regression models were applied for mortality risk. A total of 54,145 hip-fractured patients were observed (1919 oBPs; 1870 iBPs; 555 DMAB users; and 42,795 untreated patients were included in the matched sets) and followed up for a median (interquartile range) of 22.6 months (26.2). Patients treated with antiresorptive medications had significantly longer survival time than patients without treatment. Receiving treatment significantly decreased a hazard of dying only for women by 17% for iBPs (HR 0.83, 95% CI 0.71-0.98, p = 0.023). For DMAB and oBPs, the results were not statistically significant. Higher risk of a subsequent HF was observed in women on DMAB (SHR 1.77, 95% CI 1.08-2.91) and on iBP (SHR 1.81, 95% CI 1.35-2.41), and in men on oBPs (SHR 2.89, 95% CI 1.58-5.30). Patients who were treated with antiresorptive medications after HF had longer survival than patients without treatment, highlighting the importance of initiation of antiresorptive treatment after HF.

Abstract
UNLABELLED Many patients at increased risk of fractures do not take their medication appropriately, resulting in a substantial decrease in the benefits of drug therapy. Improving medication adherence is urgently needed but remains laborious, given the numerous and multidimensional reasons for non-adherence, suggesting the need for measurement-guided, multifactorial and individualized solutions. INTRODUCTION Poor adherence to medications is a major challenge in the treatment of osteoporosis. This paper aimed to provide an overview of the consequences, determinants and potential solutions to poor adherence and persistence to osteoporosis medication. METHODS A working group was organized by the European Society on Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal diseases (ESCEO) to review consequences, determinants and potential solutions to adherence and to make recommendations for practice and further research. A systematic literature review and a face-to-face experts meeting were undertaken. RESULTS Medication non-adherence is associated with increased risk of fractures, leading to a substantial decrease in the clinical and economic benefits of drug therapy. Reasons for non-adherence are numerous and multidimensional for each patient, depending on the interplay of multiple factors, suggesting the need for multifactorial and individualized solutions. Few interventions have been shown to improve adherence or persistence to osteoporosis treatment. Promising actions include patient education with counselling, adherence monitoring with feedback and dose simplification including flexible dosing regimen. Recommendations for practice and further research were also provided. To adequately manage adherence, it is important to (1) understand the problem (initiation, implementation and/or persistence), (2) to measure adherence and (3) to identify the reason of non-adherence and fix it. CONCLUSION These recommendations are intended for clinicians to manage adherence of their patients and to researchers and policy makers to design, facilitate and appropriately use adherence interventions.

Denosumab utilization among older adults in Ontario: patient characteristics, persistence with therapy, and return to therapy after an extended gap. Osteoporos Int 2019; 30:1865-1872. [PMID: 31317248 DOI: 10.1007/s00198-019-05051-1] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/23/2018] [Accepted: 06/06/2019] [Indexed: 10/26/2022]
Abstract
UNLABELLED We studied 46,797 older adults who initiated denosumab in Ontario, Canada. Patient characteristics remained relatively stable over time and aligned with public reimbursement restrictions. Almost half of patients persisted with therapy for at least 3 years. Fifty-nine percent of patients who discontinued denosumab returned to treatment within 3.6 years. INTRODUCTION The purpose of this study was to describe the characteristics of patients who initiated denosumab and estimate persistence with therapy. METHODS We identified older adults (aged ≥ 66 years) in Ontario who initiated denosumab between 2012/02 and 2015/03 and followed them to 2016/03. Patient characteristics were summarized using medical and pharmacy claims in the year before starting denosumab and osteoporosis drug use considered since 1996/10. Persistence with denosumab and return after discontinuation (> 90-day gap) were estimated using Kaplan-Meier curves. Analyses were stratified by community and long-term care (LTC) residence. RESULTS We identified 46,797 patients (monthly mean = 1263, SD = 187); 97% female, 13% LTC. Community-dwelling patients had a higher prevalence of bone mineral density testing (62% vs. 5%), yet were younger (mean age 78.5 vs. 86.6 years) and had lower prevalence of hip fractures (3% vs. 10%) compared to LTC patients. Eighty-two percent of patients had used osteoporosis medications in the past; 99% of whom took an oral bisphosphonate. Persistence was similar between community-dwelling and LTC patients: 59% persisted ≥ 2 years, 48% ≥ 3 years, and 38% ≥ 4 years, yet a larger proportion of LTC patients returned to denosumab after discontinuation (76% vs. 57%). CONCLUSIONS Denosumab utilization is increasing at a steady rate in Ontario. However, persistence remains a concern given the highly reversible pharmacokinetic profile of denosumab that results in a rapid increased fracture risk following discontinuation. Over 80% of patients had a history of oral bisphosphonate therapy, which may persist in bone despite discontinuing denosumab. Consequently, better understanding of denosumab safety and effectiveness among real-world users is important.

Abstract
Bone resorption, initiated by osteoclasts (OCs), plays an essential role in bone homeostasis. The abnormalities of bone resorption may induce a series of diseases, including osteoarthritis, osteoporosis and aseptic peri-implant loosening. Nirogacestat (PF-03084014, PF), a novel gamma-secretase inhibitor, has been used in phase II clinical trial for treatment of desmoid tumor. However, whether it has the therapeutic effect on abnormal bone resorption remains to be evaluated. In this study, we investigated the role of PF in the regulation of receptor activator of nuclear factor-kB ligand (RANKL)-induced osteoclastogenesis in vitro, and the lipopolysaccharide (LPS)-induced bone resorption in vivo. It was found that PF could suppress the formation of osteoclasts from bone marrow macrophages (BMMs) without causing cytotoxicity, inhibit bone resorption and downregulate the mRNA level of osteoclast-specific markers, including calcitonin receptor (CTR), tartrate resistant acid phosphatase (TRAP), cathepsin K (CTSK), dendritic cell-specific transmembrane protein (Dc-stamp), Atp6v0d2 (V-ATPase d2) and nuclear factor of activated T-cells cytoplasmic 1 (NFATc1). Furthermore, Notch2 signaling, as well as RANKL-induced AKT signaling was significantly inhibited in BMMs. Consistent with in vitro observation, we found that PF greatly ameliorated LPS-induced bone resorption. Taken together, our study demonstrated that PF has a great potential to be used in management of osteolytic diseases.

Abstract
OBJECTIVE The objective is to formulate clinical practice guidelines for the pharmacological management of osteoporosis in postmenopausal women. CONCLUSIONS Evidence from clinical trials and insights from clinical experience with pharmacologic therapies for osteoporosis were critically evaluated in formulating this guideline for the management of postmenopausal osteoporosis. Patient preferences, data on adherence and persistence, and risks and benefits from the patient and provider perspectives were also considered in writing committee deliberations. A consensus by the Writing Committee members was achieved for four management principles: (i) The risk of future fractures in postmenopausal women should be determined using country-specific assessment tools to guide decision-making. (ii) Patient preferences should be incorporated into treatment planning. (iii) Nutritional and lifestyle interventions and fall prevention should accompany all pharmacologic regimens to reduce fracture risk. (iv) Multiple pharmacologic therapies are capable of reducing fracture rates in postmenopausal women at risk with acceptable risk-benefit and safety profiles.

Abstract
INTRODUCTION French authorities have approved the reimbursement of denosumab as a second-line therapy after bisphosphonates (BPs) in women presenting with postmenopausal osteoporosis (PMO) at high risk of fracture. By using a nationally representative claims database, we analyzed the pattern of denosumab use. The objectives of this study were to describe the profile of women initiated with denosumab over the 14-month period after launch and to check as far back as possible for the appropriateness of its use regarding the restrictions brought by French health authorities. METHODS A retrospective study using a national representative claims database, i.e., the "Echantillon Généraliste des Bénéficiaires" (EGB), was performed. The population was composed of women aged ≥ 40 years old who had an initiation of a PMO treatment in 2013 or 2014. The denosumab women's profiles were compared with those of women that started any other PMO treatment (except denosumab) over the same period. RESULTS In 2013 and 2014, we identified 256 women who initiated denosumab. Denosumab was primarily prescribed by specialists (75%) compared with the other PMO treatments (37.6%). Patients on denosumab were significantly older, 73.2 versus 69.1 years old, and they more frequently had a history of fractures (20.7% versus 17.4%, NS) and chronic uptake of high-dose steroids (25% versus 22.8%, NS). Of the women initiated with denosumab, 93.8% had undergone a previous PMO treatment (during the 2005-2014 period). In 92.9% of cases, it was a BP alone or in association. CONCLUSION This study suggests satisfactory compliance of prescribers concerning the restriction of the reimbursed indication of denosumab in second line after bisphosphonates with 6.2% possible inappropriate prescriptions.

The aim of this review was to identify factors that influence patients' adherence to anti-osteoporotic therapy. Factors identified that were associated with poorer medication adherence included polypharmacy, older age, and misconceptions about osteoporosis. Physicians need to be aware of these factors so as to optimize therapeutic outcomes for patients. INTRODUCTION To identify factors that influence patients' adherence to anti-osteoporotic therapy. METHODS A systematic review of literature was performed for articles published up till January 2018 using PubMed®, PsychINFO®, Embase®, and CINAHL®. Peer-reviewed articles which examined factors associated with anti-osteoporotic medication adherence were included. Classes of anti-osteoporotic therapy included bisphosphonates, parathyroid hormone-related analogue, denosumab, selective estrogen receptor modulators, estrogen/progestin therapy, calcitonin, and strontium ranelate. Meta-analyses, case reports/series, and other systematic reviews were excluded. Identified factors were classified using the World Health Organization's five dimensions of medication adherence (condition, patient, therapy, health-system, and socio-economic domains). RESULTS Of 2404 articles reviewed, 124 relevant articles were identified. The prevalence of medication adherence ranged from 12.9 to 95.4%. Twenty-four factors with 139 sub-factors were identified. Bisphosphonates were the most well-studied class of medication (n = 59, 48%). Condition-related factors that were associated with poorer medication adherence included polypharmacy, and history of falls was associated with higher medication adherence. Patient-related factors which were associated with poorer medication adherence included older age and misconceptions about osteoporosis while therapy-related factors included higher dosing frequency and medication side effects. Health system-based factors associated with poorer medication adherence included care under different medical specialties and lack of patient education. Socio-economic-related factors associated with poorer medication adherence included current smoker and lack of medical insurance coverage. CONCLUSION This review identified factors associated with poor medication adherence among osteoporotic patients. To optimize therapeutic outcomes for patients, clinicians need to be aware of the complexity of factors affecting medication adherence.

Medication-related osteonecrosis of the jaw: definition and best practice for prevention, diagnosis, and treatment. Oral Surg Oral Med Oral Pathol Oral Radiol 2018; 127:117-135. [PMID: 30393090 DOI: 10.1016/j.oooo.2018.09.008] [Citation(s) in RCA: 162] [Impact Index Per Article: 27.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2018] [Revised: 08/16/2018] [Accepted: 09/27/2018] [Indexed: 12/20/2022]
Abstract
Skeletal complications caused by osteoporosis or bone metastases are associated with considerable pain, increased mortality, and reduced quality of life. Furthermore, such events place a burden on health care resources. Agents that prevent bone resorption, such as bisphosphonates or denosumab, can reduce the risk of skeletal-related events and are widely used in patients with osteoporosis or bone metastases of cancer. Medication-related osteonecrosis of the jaw (MRONJ) is a rare, but potentially serious, adverse event associated with high cumulative doses of bisphosphonates or denosumab. However, MRONJ can be treated, and the likelihood of the development of this condition can be reduced through prophylactic dental care and the maintenance of good oral hygiene. Dentists, as part of a multiprofessional team, have a critical role in preventing MRONJ. This review describes the incidence and pathophysiology of MRONJ and provides guidance for dental practitioners with regard to the screening, prophylactic treatment, diagnosis, and management of patients with this condition.

Abstract
Introduction Osteoporosis is characterized by low bone mineral density (BMD) and an increased risk of fracture. In randomized controlled trials, denosumab has been shown to significantly reduce the fracture risk in women with osteoporosis. However, little is known about the real-world management of women who are prescribed denosumab. Methods This multicenter, prospective, observational real-world study in the Czech Republic and Slovakia evaluated the baseline characteristics and clinical management of women with postmenopausal osteoporosis prescribed denosumab for 24 months. Results A total of 600 women were included (300 in each country). In the Czech Republic and Slovakia, respectively, mean age at enrollment was 69.0 and 64.3 years, 67.7% and 30.0% of patients had a previous osteoporotic fracture, and 85.0% and 48.7% had previously received osteoporosis medication. In both countries, ‘low BMD T score’ and ‘a history of osteoporotic fracture’ were the main reasons for prescribing denosumab. Most patients received all four post-baseline denosumab injections (Czech Republic, 82.0%; Slovakia, 81.0%), and more than 98% of patients in both countries received all injections at the prescribing center. At 24 months, most patients experienced an increase in BMD T score for the lumbar spine, total hip, or femoral neck (Czech Republic, 69.7–91.7%; Slovakia, 67.1–92.9%). Adverse drug reactions were consistent with the known safety profile of denosumab. Conclusion Baseline characteristics of patients receiving denosumab in the Czech Republic and Slovakia reflect the reimbursement criteria for this agent in each country. The findings of our study in patients who are at high risk for fracture are consistent with the growing body of evidence demonstrating the effectiveness of denosumab in real-world clinical practice.

Cost-effectiveness analysis of drugs for osteoporosis treatment in elderly Japanese women at high risk of fragility fractures: comparison of denosumab and weekly alendronate. Arch Osteoporos 2018; 13:94. [PMID: 30159632 DOI: 10.1007/s11657-018-0509-6] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/09/2018] [Accepted: 08/19/2018] [Indexed: 02/03/2023]
Abstract
UNLABELLED This study's purpose was to clarify the cost-effectiveness of osteoporosis treatment. Denosumab treatment was cost-effective compared with alendronate treatment for elderly Japanese women at high risk of fragility fractures. Denosumab treatment might be cost-effective for patients with lower bone mineral density. PURPOSE In Japan's super-aged society, the prevention and treatment of osteoporosis are a critical issue with implications for the medical economy. This study's purpose was to clarify the cost-effectiveness of osteoporosis treatment with denosumab versus weekly alendronate for elderly Japanese women at high risk of fragility fractures. METHODS A Markov model was used for simulation analysis. The modeled population was 75-year-old Japanese women with a bone mineral density (BMD) of 65% of the young adult mean (YAM) (T-score, - 2.87) and a history of previous vertebral body fracture. The simulation model was repeated until patient age reached 100 years or death. Analysis was performed from the societal perspective. Costs and epidemiological data were derived from previous studies. The incremental cost-effectiveness ratio (ICER) was calculated from the simulation. We compared the ICER with willingness-to-pay. Additional analyses were performed with different combinations of age and BMD. Sensitivity analysis verified the robustness of the analysis. RESULTS For the modeled population, the ICER of denosumab versus alendronate treatment was estimated at US$40,241/quality-adjusted life year (QALY). The ICER of denosumab for 80-year-old women whose BMD was 60% of YAM was estimated at US$22,469/QALY. CONCLUSIONS Assuming willingness-to-pay as US$50,000/QALY, denosumab treatment for 75-year-old Japanese women with a BMD of 65% of YAM and a history of previous vertebral body fracture was cost-effective compared with alendronate treatment. Among over 75 years of age, denosumab treatment might be more cost-effective than alendronate for patients with a BMD of 65% of YAM or lower.

Abstract
Denosumab (Prolia®; Pralia®) is a human monoclonal antibody targeting the key bone resorption mediator RANKL. The drug is administered via subcutaneous injection once every 6 months and is approved for various indications, including the treatment of postmenopausal (PM) women with osteoporosis at increased/high risk of fracture or failure/intolerance of other osteoporosis therapies (indications featured in this review). Denosumab showed benefit in several phase 3 or 4 studies in PM women with osteoporosis or low bone mineral density (BMD), including the pivotal 3-year double-blind FREEDOM trial and its 7-year open-label extension. Denosumab reduced the risk of vertebral, nonvertebral and hip fractures and increased BMD across skeletal sites versus placebo in FREEDOM, with these benefits maintained over up to 10 years' therapy in the extension. The drug was also more effective in improving BMD than bisphosphonates, including in women switched from a bisphosphonate regimen, in 1-year trials; however, whether these differences translate into differences in anti-fracture efficacy is unclear. Denosumab was generally well tolerated over up to 10 years' treatment, although an increased risk of multiple vertebral fractures was observed after discontinuation of the drug. Thus, denosumab is a key treatment option for PM women with osteoporosis who have an increased/high risk of fracture or failure/intolerance of other osteoporosis therapies, although the potential for multiple vertebral fractures to occur after discontinuation of the drug requires consideration of subsequent management options.

Abstract
Although fractures had high mortality and morbidity, many studies proved that fracture risk might be decreased by pharmacological therapy, although a low treatment adherence rate is observed. The aim of this study was to identify factors associated with osteoporosis treatment in postmenopausal women.A cross-sectional study was carried out from March to August 2013 at the primary care setting. Postmenopausal women were recruited. A standardized questionnaire was applied. Women who were using at least one of the following drugs at the moment of the survey were considered as current treatment: bisphosphonates, raloxifene, estrogen, calcitonin, teriparatide, or strontium ranelate. Women who had used any of the mentioned medications before the study were considered as past treatment.Of the 1025 women included in the study, 8% were on current treatment, 5.7% had past treatment, and 86.3% had not received treatment. Treated women (either current or past) had a higher rate of osteoarthritis, had more falls, had higher education level, presented a higher rate of private health insurance, and received more information about osteoporosis. They also had more dual-energy x-ray absorptiometry (DXA) scans and were more frequently diagnosed with osteoporosis by these DXA scans. The factors independently associated with treatment in the regression analysis were the DXA scan itself, the diagnosis of osteoporosis by DXA, and information about osteoporosis.Current and past treatments of osteoporosis were associated with DXA and information. These results suggest that some measures to inform women about osteoporosis and or even the popularization of DXA scans could improve the treatment.
