Abstract
CONTEXT The comparative effectiveness of denosumab and zoledronic acid for adult patients with osteogenesis imperfecta (OI) has not been established. OBJECTIVE To evaluate the efficacy and safety of denosumab and zoledronic acid in adult patients with OI. METHODS This was a prospective, open-label study. Patients were randomized to receive denosumab 60 mg every 6 months or zoledronic acid 5 mg once for 12 months. Pathogenic mutations of OI were identified by next-generation sequencing and confirmed by Sanger sequencing. Percentage changes in the areal bone mineral density (aBMD), trabecular bone score (TBS), and bone turnover biomarkers (BTMs) from baseline to 6 and 12 months of treatment, as well as safety, were evaluated. RESULTS A total of 51 adults with OI (denosumab: 25, zoledronic acid: 26) were included, of whom 49 patients had identified pathogenic mutations. At 12 months, aBMD at the lumbar spine and total hip significantly increased by 4.34% (P = .005) and 1.45% (P = .023) in the denosumab group and by 4.92% (P = .006) and 2.02% (P = .016) in the zoledronic acid group, respectively. TBS showed an increasing trend by 1.39% and 2.70% in denosumab and zoledronic acid groups, respectively. Serum levels of β-isomerized carboxy-telopeptide of type I collagen and alkaline phosphatase markedly decreased after denosumab treatment. Percentage changes in aBMD, TBS, and BTMs during the treatment were similar between the 2 groups. Patients with OI with milder phenotypes showed a significantly higher increase in the TBS after 12 months of denosumab treatment than those with more severe phenotypes (P = .030). During the study period, the denosumab group had fewer adverse events than the zoledronic acid group. CONCLUSION Denosumab effectively increases aBMD in adults with OI, with similar efficacy to zoledronic acid. Long-term and large-sample studies are needed to confirm the antifracture efficacy and safety of denosumab in adult patients with OI.

J Endocrinol Invest 2024:10.1007/s40618-024-02395-2.

Abstract
BACKGROUND Romosozumab, a fully humanized anti-sclerostin-antibody, is a bone-builder stimulating osteoblasts and inhibiting osteoclast by activation of the canonical Wnt-beta catenin signaling. This unique mechanism of action has the potential to address unmet needs in osteoporosis management. METHODS The multifaceted practical clinical issues related to romosozumab are discussed, especially focusing on the rationale of employing a sclerostin inhibitor to target bone fragility as first line or second line treatment in post-menopausal osteoporosis and in males at increased risk of fractures. RESULTS Four randomized clinical trials with several post-hoc analyses and more than ten observational studies have consistently demonstrated that romosozumab is effective in rapidly increasing bone mineral density (BMD) and decreasing risk of vertebral, non-vertebral and hip fractures in post-menopausal women at very-high risk of fractures. In male osteoporosis, only data on BMD are available. Noteworthy, romosozumab was shown to be more effective and rapid than teriparatide in improving BMD, bone structure and strength at the hip, especially in women already treated with anti-resorptive drugs. Interestingly, even if romosozumab displays best results in treatment-naïve patients, its favourable effects on BMD were observed even in women previously treated with teriparatide or denosumab, although to a lesser extent. CONCLUSIONS Based on the available evidence, romosozumab could be proposed as ideal drug in several clinical settings, such as non-fractured post-menopausal women at very-high risk of fractures, patients with recent hip fracture, patients non responder to bisphosphonates and short-term denosumab therapy.

Update on the clinical use of trabecular bone score (TBS) in the management of osteoporosis: results of an expert group meeting organized by the European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO), and the International Osteoporosis Foundation (IOF) under the auspices of WHO Collaborating Center for Epidemiology of Musculoskeletal Health and Aging. Osteoporos Int 2023; 34:1501-1529. [PMID: 37393412 PMCID: PMC10427549 DOI: 10.1007/s00198-023-06817-4] [Citation(s) in RCA: 13] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Accepted: 05/31/2023] [Indexed: 07/03/2023]
Abstract
PURPOSE Trabecular bone score (TBS) is a grey-level textural measurement acquired from dual-energy X-ray absorptiometry lumbar spine images and is a validated index of bone microarchitecture. In 2015, a Working Group of the European Society on Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO) published a review of the TBS literature, concluding that TBS predicts hip and major osteoporotic fracture, at least partly independent of bone mineral density (BMD) and clinical risk factors. It was also concluded that TBS is potentially amenable to change as a result of pharmacological therapy. Further evidence on the utility of TBS has since accumulated in both primary and secondary osteoporosis, and the introduction of FRAX and BMD T-score adjustment for TBS has accelerated adoption. This position paper therefore presents a review of the updated scientific literature and provides expert consensus statements and corresponding operational guidelines for the use of TBS. METHODS An Expert Working Group was convened by the ESCEO and a systematic review of the evidence undertaken, with defined search strategies for four key topics with respect to the potential use of TBS: (1) fracture prediction in men and women; (2) initiating and monitoring treatment in postmenopausal osteoporosis; (3) fracture prediction in secondary osteoporosis; and (4) treatment monitoring in secondary osteoporosis. Statements to guide the clinical use of TBS were derived from the review and graded by consensus using the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) approach. RESULTS A total of 96 articles were reviewed and included data on the use of TBS for fracture prediction in men and women, from over 20 countries. The updated evidence shows that TBS enhances fracture risk prediction in both primary and secondary osteoporosis, and can, when taken with BMD and clinical risk factors, inform treatment initiation and the choice of antiosteoporosis treatment. Evidence also indicates that TBS provides useful adjunctive information in monitoring treatment with long-term denosumab and anabolic agents. All expert consensus statements were voted as strongly recommended. CONCLUSION The addition of TBS assessment to FRAX and/or BMD enhances fracture risk prediction in primary and secondary osteoporosis, adding useful information for treatment decision-making and monitoring. The expert consensus statements provided in this paper can be used to guide the integration of TBS in clinical practice for the assessment and management of osteoporosis. An example of an operational approach is provided in the appendix. This position paper presents an up-to-date review of the evidence base, synthesised through expert consensus statements, which informs the implementation of Trabecular Bone Score in clinical practice.

Effect of Abaloparatide on Bone Microarchitecture Assessed by Trabecular Bone Score in Women With Osteoporosis: Post Hoc Analysis of ACTIVE and ACTIVExtend. J Bone Miner Res 2023; 38:464-470. [PMID: 36588166 DOI: 10.1002/jbmr.4764] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/15/2022] [Revised: 12/12/2022] [Accepted: 12/29/2022] [Indexed: 01/03/2023]
Abstract
Although bone mineral density (BMD) is a predictor of fracture, many fractures occur in women with T-scores > -2.5. Bone microarchitecture, assessed by trabecular bone score (TBS), predicts fracture risk independent of BMD. We evaluated whether abaloparatide improves TBS and whether TBS trends were associated with vertebral fracture risk reduction. Women with osteoporosis randomized to abaloparatide or placebo for 18 months (ACTIVE), followed by alendronate for 24 months (ACTIVExtend), with evaluable TBS, were included in this post hoc analysis (N = 911). TBS was calculated from spine BMD scans using an algorithm adjusted for tissue thickness (TBSth ) at baseline, 6, 18, and 43 months. Mean increments in TBSth from baseline within and between treatment groups, proportion of women with TBSth increments above least significant change (LSC) and proportion with degraded TBSth (<1.027) were calculated. Risk estimates for vertebral fracture were compared using binary logistic regressions adjusted for baseline age and spine BMD. At baseline, 42% had degraded TBSth . Mean TBSth increased 4% after 18 months abaloparatide (p < 0.001) and was unchanged with placebo. After 2 subsequent years of alendronate, the total cumulative TBSth increase was 4.4% with abaloparatide/alendronate and 1.7% with placebo/alendronate (group difference, p < 0.001). At 43 months, the proportion of women with degraded TBSth had declined to 21% with abaloparatide/alendronate and 37% with placebo/alendronate (p < 0.05). An increase in TBSth ≥ LSC was observed in 50% of abaloparatide-treated women at 18 months and was associated with decreased odds (odds ratio [OR]; 95% confidence interval [CI]) of vertebral fracture (0.19; 95% CI, 0.04-0.80, 6 months; 0.30; 95% CI, 0.11-0.79, 43 months). In conclusion, abaloparatide increased TBSth rapidly and progressively over 18 months and increments were maintained over 2 years with alendronate. TBSth increase was associated with vertebral fracture risk reduction. Microarchitectural improvement may be one mechanism by which abaloparatide strengthens vertebral bone. © 2023 Radius Health, Inc and The Authors.

Abstract
It is now well recognized that over the lifetime of a patient with osteoporosis, more than one medication will be needed to treat the disease and to decrease fracture risk. Though current gaps in osteoporosis therapy can be potentially mitigated with sequential and combination regimens, how to move seamlessly amongst the multiple treatments currently available for osteoporosis for sustained efficacy is still unclear. Data from recent studies show that an anabolic agent such as teriparatide or romosozumab followed by an antiresorptive affords maximal gain in BMD and possibly better and earlier fracture risk reduction compared to a regimen which follows the opposite sequence. Sequentially moving to a bisphosphonate such as alendronate from an anabolic agent such as abaloparatide has also been shown to preserve the fracture reduction benefits seen with the latter. This sequence of an anabolic agent followed by an antiresorptive should especially be considered in the high-risk patient with imminent fracture risk to rapidly reduce the risk of subsequent fractures. The data surrounding optimum timing of initiation of bisphosphonate therapy following denosumab discontinuation is still unclear. Though data suggests that combining a bisphosphonate with teriparatide does not provide substantial BMD gains compared to monotherapy, the concomitant administration of denosumab with teriparatide has been shown to significantly increase areal BMD as well as to increase volumetric BMD and estimated bone strength. This narrative review explores the available evidence regarding the various sequential and combination therapy approaches and the potential role they could play in better managing osteoporosis.

Abstract
Osteoporosis constitutes a significant public health risk. An estimated 10.2 million adults in the United States >50 years of age have osteoporosis, a systemic condition that weakens the bones increasing the susceptibility for fractures. Approximately one-half of women and nearly one-third of men >50 years of age will sustain an osteoporotic fracture. These fractures are associated with a decrease in quality of life, diminished physical function, and reduced independence. Dual-energy X-ray absorptiometry (DXA) is the primary imaging modality used to screen for osteoporosis in women >65 years of age and men >70 years of age. DXA may be used in patients <65 years of age to evaluate bone mass density if there are additional risk factors. In certain situations, vertebral fracture assessment and trabecular bone score may further predict fracture risk, particularly in patients who are not yet osteoporotic but are in the range of osteopenia. Quantitative CT is useful in patients with advanced degenerative changes in the spine. Given the proven efficacy of pharmacologic therapy, the role of imaging to appropriately identify and monitor high-risk individuals is critical in substantially reducing osteoporosis-associated morbidity and mortality, and reducing the considerable cost to the health care system. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

Abstract
CONTEXT Premenopausal women with idiopathic osteoporosis (PreMenIOP) have marked deficits in bone density, microstructure, and strength. OBJECTIVE To define effects of treatment with teriparatide followed by denosumab on lumbar spine (LS) volumetric bone mineral density (vBMD) and stiffness by finite element analysis assessed on central quantitative computed tomography (cQCT) scans. DESIGN, SETTINGS, AND PARTICIPANTS Ancillary analysis of baseline, post-teriparatide, and post-denosumab cQCT scans from a randomized trial of 41 women allocated to teriparatide (20 mcg daily; n = 28) or placebo (n = 11). After 6 months, those on teriparatide continued for 18 months, and those on placebo switched to teriparatide for 24 months. After completing teriparatide, 33 enrolled in a Phase 2B extension with denosumab (60 mg every 6 months) for 12 months. MAIN OUTCOME MEASURES Primary outcomes were percentage change from baseline in LS trabecular vBMD and stiffness after teriparatide and between end of teriparatide and completing denosumab. Percentage change from baseline in LS trabecular vBMD and stiffness after sequential teriparatide and denosumab were secondary outcomes. FINDINGS There were large increases (all Ps < 0.001) in trabecular vBMD (25%), other vBMD parameters, and stiffness (21%) after teriparatide. Statistically significant increases in trabecular vBMD (10%; P < 0.001) and other vBMD parameters (P = 0.03-0.001) were seen after denosumab, while stiffness increased by 7% (P = 0.068). Sequential teriparatide and denosumab led to highly significant (all Ps < 0.001) increases LS trabecular vBMD (43%), other vBMD parameters (15-31%), and stiffness (21%). CONCLUSIONS The large and statistically significant increases in volumetric density and stiffness after sequential treatment with teriparatide followed by denosumab are encouraging and support use of this regimen in PreMenIOP.

Abstract
CONTEXT We have previously reported that teriparatide is associated with substantial increases in bone mineral density (BMD) at the lumbar spine (LS), total hip (TH), and femoral neck (FN) and small declines at the distal radius in 41 premenopausal women with idiopathic osteoporosis (IOP), all severely affected with low trauma fractures and/or very low BMD. Effects of teriparatide dissipate if not followed by antiresorptives. OBJECTIVE To assess the effects of 12 and 24 months of denosumab in premenopausal women with IOP completing 24 months of teriparatide. METHODS This was a preplanned phase 2B extension study. Premenopausal women with IOP who had completed a course of teriparatide received denosumab 60 mg every 6 months over 24 months. The main outcome measure was within-group change in BMD at the LS at 12 months. Secondary outcomes include change in 12-month BMD at other sites, 24-month BMD at all sites, trabecular bone score (TBS), and bone turnover markers (BTMs). RESULTS After completing teriparatide, 32 participants took denosumab for 12 months and 29 for 24 months, with statistically significant increases in BMD at the LS (5.2 ± 2.6% and 6.9 ± 2.6%), TH (2.9 ± 2.4% and 4.6 ± 2.8%), and FN (3.0 ± 3.8% and 4.7 ± 4.9%). Over the entire 24-month teriparatide and 24-month denosumab treatment period, BMD increased by 21.9 ± 7.8% at the LS, 9.8 ± 4.6% at the TH, and 9.5 ± 4.7% at the FN (all P < .0001). TBS increased by 5.8 ± 5.6% (P < .001). Serum BTM decreased by 75% to 85% by 3 months and remained suppressed through 12 months of denosumab. Denosumab was generally well tolerated. CONCLUSION These data support the use of sequential teriparatide and denosumab to increase BMD in premenopausal women with severe osteoporosis.

[PMID: 34132853 DOI: 10.1007/s00223-021-00871-y] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/11/2021] [Accepted: 05/31/2021] [Indexed: 10/21/2022]
Abstract
Pregnancy- and lactation-associated osteoporosis (PLO) is a rare disease, presenting in most cases with severe back pain due to low energy vertebral fractures (VFs). Our purpose was to assess the effect of teriparatide (TPTD) vs. conventional management on areal bone mineral density (aBMD) and trabecular bone score (TBS) in patients with PLO. A multicenter retrospective cohort study concerning premenopausal women with PLO. Nineteen women were treated with TPTD (20 μg/day) (group A) plus calcium and vitamin D and eight women with calcium and vitamin D only (group B) for up to 24 months. The primary end-point was between group differences in lumbar spine (LS) and total hip (TH) aBMD, and TBS at 12 and 24 months. Patients in group A had sustained a median of 4.0 VFs (3-9) vs. 2.5 VFs (1-10) in group B (p = 0.02). At 12 months, patients on TPTD vs. controls achieved a mean aBMD increase of 20.9 ± 11.9% vs. 6.2 ± 4.8% at the LS (p < 0.001), 10.0 ± 11.6% vs. 5.8 ± 2.8% at the TH (p = 0.43), and 6.7 ± 6.9% vs. 0.9 ± 3.7% in TBS (p = 0.09), respectively. At 24 months, seven patients on TPTD and six controls achieved a mean LS aBMD increase of 32.9 ± 13.4% vs. 12.2 ± 4.2% (p = 0.001). P1NP levels during the first month of TPTD treatment were positively correlated with the 1-year LS aBMD change (r = 0.68, p = 0.03). No new clinical fractures occurred while on-treatment. In patients with PLO, TPTD treatment resulted in significantly greater increases in LS aBMD compared with calcium and vitamin D supplementation at 12 and 24 months.

Romosozumab versus Teriparatide for the Treatment of Postmenopausal Osteoporosis: A Systematic Review and Meta-analysis through a Grade Analysis of Evidence. Orthop Surg 2021; 13:1941-1950. [PMID: 34643048 PMCID: PMC8528978 DOI: 10.1111/os.13136] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2021] [Revised: 06/08/2021] [Accepted: 06/29/2021] [Indexed: 11/28/2022] Open
Abstract
OBJECTIVE To provide a systematic review about the efficacy and safety of romosozumab and teriparatide for the treatment of postmenopausal osteoporosis. METHOD Randomized controlled trials (RCTs) were searched from electronic databases, including PubMed (1996 to June 2019), Embase (1980 to June 2019), Cochrane Library (CENTRAL, June 2019), Web of Science (1998 to June 2019), and others. The primary outcomes included the following: the percentage change in bone mineral density of lumbar spine and total hip from baseline at month 6 and month 12 in each group. The secondary outcomes included the following: the percentage change in bone mineral density of femoral neck from baseline at month 6 and month 12 in each group and the incidence of adverse events at month 12 in each group. RESULTS Four studies containing 1304 patients met our selection criteria. The result of our analysis indicated that romosozumab showed better effects in improving BMD of lumbar spine (month 6: MD = 3.54, 95% CI [3.13, 3.94], P<0.001; month 12: MD = 4.93, 95% CI [4.21, 5.64], P<0.001), total hip (month 6: MD = 2.27, 95% CI [0.62, 3.91], P = 0.007; month 12: MD = 3.17, 95% CI [2.68, 3.65], P<0.001), and femoral neck (month 6: MD = 2.30, 95% CI [0.51, 4.08], P = 0.01; month 12: MD = 3.04, 95% CI [2.29, 3.78], P<0.001). Also, the injection-site reaction was less (month 12: RR = 2.84, 95% CI [1.22, 6.59], P = 0.02), but there were no significant difference in the incidence of serious adverse events (month 12: RR = 0.78, 95% CI [0.46, 1.33], P = 0.37) and death (month 12: RR = 0.61, 95% CI [0.08, 4.62], P = 0.63). CONCLUSION Based on the available studies, our current results demonstrate that romosozumab was better than teriparatide both in terms of efficacy and side effects.

Abstract
Introduction: Osteoporosis is characterized by the fragility of bones, leading to fractures and, consequently, the deterioration of functional capacity and quality of life. Postmenopausal women, in particular, are prone to osteoporosis and often require anti-osteoporosis treatment. In the last few decades, various anti-osteoporosis drugs have been approved for clinical use. In an aging society, osteoporosis cannot be treated using a single agent; therefore, switching therapy is an important treatment strategy.Areas covered: This review covers switching therapy in patients with postmenopausal osteoporosis. It's extremely important to understand the characteristics of each drug including; limitations on the duration of use, side effects due to long-term use (such as atypical femur fracture and osteonecrosis of the jaw) or discontinuation (such as rebound phenomenon), compliance, and ability to prevent fractures. We review and summarize the risks and benefits of switching therapy.Expert opinion: When switching therapy, the order of drug administration is important. Routine monitoring should be continued after switching treatments. We recommend first using osteoanabolic agents in postmenopausal women with severe osteoporosis. In addition, identifying predictors of the efficacy and side effects of treatment may help prevent the inappropriate use of drugs for the treatment of osteoporosis.

Abstract
Teriparatide (TPTD) is a bone-forming agent used to treat postmenopausal osteoporosis. Since hip fractures are related to higher morbidity and mortality rates than other fractures, efficacious osteoporosis drugs for the hip are critical. We reviewed research articles reporting the efficacy of TPTD in terms of bone mineral density (BMD), fractures prevention, changes in the outer diameter, cortical thickness and porosity, post-operative periprosthetic BMD loss, and healing of typical and atypical fractures of the hip. Data meta-analyses indicated that TPTD not only increased the BMD of the proximal femur but also decreased the risk of hip fractures. Even though TPTD increases the cortical bone porosity of the proximal femur, the bone strength does not decrease as the majority of the porosity is located at the endocortex; further, it increases the outer diameter and thickens the cortical bone. TPTD stimulates bone remodeling and facilitates callus maturity and fracture healing. There have been many reports on improving the effect of TPTD on the healing of atypical fractures; therefore it is advisable to use TPTD considering the increase benefit compared to the risk.

Abstract
PURPOSE OF REVIEW There are now three anabolic agents available for the treatment of postmenopausal women at high risk for fracture. The purpose of this review is to supply a rationale to aid in determining which agent should be used in which clinical settings. RECENT FINDINGS Studies over the last decade have shown that anabolic agents produce faster and larger effects against fracture than antiresorptive agents. Furthermore, trials evaluating anabolic antiresorptive treatment sequences have shown that anabolic first treatment strategies produce the greatest benefits to bone density, particularly in the hip region. However, there are no head-to-head evaluations of the three anabolic therapies with fracture outcomes or bone density, and these studies are not likely to occur. How to decide which agent to use at which time in a woman's life is unknown. We review the most significant clinical trials of anabolic agents which have assessed fracture, areal or volumetric bone density, microarchitecture, and/or bone strength, as well as information gleaned from histomorphometry studies to provide a rationale for consideration of one agent vs another in various clinical settings. There is no definitive answer to this question; all three agents increase bone strength and reduce fracture risk rapidly. Since the postmenopausal lifespan could be as long as 40-50 years, it is likely that very high-risk women will utilize different anabolic agents at different points in their lives.

Abstract
Objective: Trabecular bone score (TBS) is a novel index for assessing bone microarchitecture quality. No bibliometric reviews to date have yet explored the literature of TBS. Therefore, this study aimed to provide a bibliometric review on the trends of research publications on TBS indexed in the Science Citation Index Expanded and the Social Sciences Citation Index from 2008 to 2019. Materials and Methods: Using the Science Citation Index Expanded and the Social Sciences Citation Index, articles designated as original articles or review articles were searched using the keyword “trabecular bone score.” The retrieved articles were analyzed using Histcite 12.03.17 and VOSviewer v. 1.6.15 to identify top authors, journals, countries, and occurrence of keywords. Results: A total of 430 original and review articles on TBS published between 2008 and 2019 were identified. The number of articles increased steadily from 2008 to 2019, reaching 80 articles in 2019 alone. The United States of America, Switzerland, and France were the countries with the highest output of publications. The journal Osteoporosis International published the largest number of articles on TBS. Analysis of co-occurrence of author-supplied keywords revealed four clusters, with TBS, bone mineral density, and osteoporosis as the most prominent keywords. Conclusion: This bibliometric study on TBS published between 2008 and 2019 revealed the collaborative network of countries and the highly published journals and authors. Co-occurrence of keywords also revealed clusters of research hotspots, which could contribute to the understanding of the current state of TBS research and the identification of research gap.

Abstract
Background Sequential therapy from bone-forming medication to resorptive agents is reportedly effective for patients with severe osteoporosis. The objective of this study is to determine the impact of implementing short-term teriparatide (TPTD) intervention before denosumab (DMab) therapy compared with DMab therapy alone for 1 year after hip fracture. Methods We retrospectively reviewed the medical records and radiographs of patients who were treated due to osteoporotic hip fracture. TPTD was administered to 22 patients for an average of 12.1 weeks after which the intervention was switched to DMab therapy for 12 months (group 1). DMab alone was administered to 16 patients for 12 months (group 2). Bone mineral density (BMD) was evaluated before and after treatment at the 1-year follow-up. The improvement of BMD in hip and spine was compared with the levels of bone turnover marker. Results The difference in femoral neck BMD was 0.005 ± 0.04 in group 1 and − 0.014 ± 0.10 in group 2 (p = 0.442). The difference of spine BMD was 0.043 ± 0.05 in group 1 and 0.052 ± 0.06 in group 2 (p = 0.640). BMD of the spine improved significantly in groups 1 and 2 (p < 0.001, p = 0.002). There was no statistical difference in C-terminal telopeptide and osteocalcin level. Conclusion Short-term TPTD administration followed by DMab alone was effective only in improving spine BMD. Short-term treatment with TPTD caused mild improvement in femur neck BMD compared with DMab alone. However, further research with a longer duration of TPTD treatment is warranted, as our findings lack statistical significance.

Abstract
CONTEXT Premenopausal women with idiopathic osteoporosis (IOP) have abnormal skeletal microarchitecture and variable tissue-level bone formation rate (BFR). OBJECTIVES Compare 6 months (M) of teriparatide versus placebo on areal bone mineral density (aBMD) by dual-energy x-ray absorptiometry (DXA), bone turnover markers (BTMs) and BFR at 3M by quadruple-labeled transiliac biopsy. Characterize 12M and 24M effects of teriparatide on aBMD and whether BTMs and BFR predict response. DESIGN 6M phase 2 randomized controlled trial (RCT) followed by open extension. SETTING Tertiary referral centers. PATIENTS Premenopausal women with IOP. INTERVENTIONS A total of 41 women were randomized to either teriparatide 20 mcg (n = 28) or placebo (n = 13). After 6M, those on placebo switched to teriparatide for 24M; those on teriparatide continued for 18M. MAIN OUTCOME MEASURES 6M RCT: Between-group differences in lumbar spine (LS) aBMD (percent change from baseline), 3M BFR, and hypercalcemia. Open-label extension: Within-group change in LS aBMD over 12M and 24M. Secondary outcomes included aBMD change at other sites and relationship between BTMs, BFR, and changes in aBMD. FINDINGS Over 6M, LS aBMD increased by 5.5% (95% CI: 3.83, 7.19) in teriparatide and 1.5% (95% CI: -0.73, 3.83) in placebo (P = 0.007). There were increases in 3M BTMs, and BFR (cancellous and endocortical BFR: between-groups P = 0.004). Over 24M, teriparatide increased LS aBMD by 13.2% (95% CI: 10.3, 16.2), total hip by 5.2% (95% CI: 3.7, 6.7) and femoral neck by 5.0% (95% CI: 3.2, 6.7; all P ≤ 0.001). Serum N-terminal propeptides of procollagen type 1 (P1NP) and 3M endocortical BFR were moderately associated with LS aBMD response. Teriparatide was well-tolerated. CONCLUSIONS Teriparatide increased BFR and formation markers and was associated with marked aBMD improvements in most premenopausal women (82%) with IOP.

Abstract
Denosumab is a receptor activator of nuclear factor kappa-Β ligand inhibitor, which suppresses the bone resorption process to preserve bone mass. It is usually recommended to postmenopausal women and men with high fracture risk. With the recent publication of the results from FREEDOM study and its extension, the long-term effect of denosumab in preventing fragility fractures has been put forward. This review aims at summarising the evidence of denosumab in reducing fracture risk and its safety derived from clinical studies. Most of the evidence are derived from FREEDOM trials up to 10 years of exposure. Denosumab is reported to prevent vertebral and non-vertebral fractures. It is also proven effective in Japanese women, patients with chronic kidney diseases and breast cancer patients receiving antineoplastic therapy. Denosumab discontinuation leads to high remodeling, loss of bone mineral density and increased fracture risk. These negative effects might be preventable by bisphosphonate treatment. The safety profile of denosumab is consistent with increased years of exposure. In conclusion, denosumab is a safe and effective option for reducing fracture risk among patients with osteoporosis.

Abstract
Introduction: The effects of ageing on bone can be mitigated with different types of physical training, such as power training. However, stimuli that combine increasing external and internal loads concomitantly may improve bone quality. The goal of this study was to assess the efficacy of a combined power and plyometric training on lumbar spine and distal tibia microstructure and function. Methods: 38 sedentary elderly women between 60 and 70 years were randomly allocated in experimental (N = 21) and control group (N = 17). The effects of the 20-week protocol on lumbar spine microstructure and tibia microstructure and function were assessed by trabecular bone score (TBS), high resolution peripheral quantitative computed tomography (HR-pQCT) and microfinite element analysis. Results: when compared to the effects found in the control group, the experimental group showed significant improvements in lumbar spine TBS (Hedges' g = 0.77); and in distal tibia trabecular thickness (g = 0.82) and trabecular bone mineral density (g=0.63). Conclusion: our findings underscore the effectiveness of the proposed intervention, suggesting it as a new strategy to slow down and even reverse the structural and functional losses in the skeletal system due to ageing.

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
Several antiresorptive drugs, like bisphosphonates and denosumab, are currently available for the treatment of osteoporosis due to their evidenced efficacy in reducing fracture risk at mid-term. Osteoanabolic therapies, like teriparatide, whose treatment duration is limited to 2 years, have also shown efficacy in the reduction of fracture risk. However, depending on the severity of osteoporosis and the presence of other associated risk factors for fracture, some patients may require long-term treatment to preserve optimal bone strength and minimize bone fracture risk. Given the limited duration of some treatments, the fact that most of the antiresorptive drugs have not been assessed beyond 10 years, and the known long-term safety issues of these drugs, including atypical femoral fractures or osteonecrosis of the jaw, the long-term management of these patients may require an approach based on drug discontinuation and/or switching. In this regard, interest in sequential osteoporosis therapy, wherein drugs are initiated and discontinued over time, has grown in recent years, although the establishment of an optimal and individualized order of therapies remains controversial. This review reports the currently available clinical evidence on the discontinuation effects of different anti-osteoporotic drugs, as well as the clinical outcomes of the different sequential treatment regimens. The objective of this article is to present up-to-date practical knowledge on this area in order to provide guidance to the clinicians involved in the management of patients with osteoporosis.

Abstract
Abstract
Background
Kidney transplant recipients (KTR) are at risk to lose bone mass. The trabecular bone score (TBS) represents a recently developed parameter of lumbar spine trabecular bone texture that correlates with the occurrence of fractures.
Methods
We analysed the 1-year changes in TBS in 44 de novo KTR that were randomized 1:1 to denosumab or no treatment. TBS was derived from dual energy X-ray absorptiometry and was correlated with 1-year areal bone mineral density (aBMD) changes at the lumbar spine and total hip. Correlations were also performed with parameters of peripheral bone microarchitecture and bone strength at the distal tibia and distal radius, as assessed by high-resolution peripheral quantitative computed tomography (HRpQCT) and micro-finite element analysis.
Results
The baseline TBS in KTR amounted to 1.312 ± 0.101, which is lower than the TBS of an age-matched normal control population (range 1.364–1.471). The TBS correlated positively with aBMD at the lumbar spine (Spearman’s ρ = 0.56; P < 0.001) and total hip (ρ = 0.33; P < 0.05). The baseline TBS also correlated with HRpQCT-derived total (ρ = 0.49; P < 0.05) and trabecular volumetric BMD (ρ = 0.57; P < 0.01) and trabecular separation (ρ = −0.46; P < 0.05) at the tibia. Denosumab treatment led to an increase in TBS, paralleling the BMD changes at the lumbar spine.
Conclusions
The TBS is a useful additional score of bone health, which may help to better define fracture risk. Treatment with denosumab led to improved trabecular bone texture in de novo KTR in addition to its beneficial effect on BMD.

Abstract
OBJECTIVE Denosumab is an antiresorptive drug with demonstrated efficacy in the treatment of osteoporosis. However, discontinuation of this agent is associated with increased bone turnover and rapid bone loss, and more recently, with the development of vertebral fractures (VF) in some patients. Therefore, the aim of the study was to analyze the clinical characteristics, bone metabolism parameters and evolution of a group of patients who developed vertebral fractures after denosumab discontinuation. In addition, we reviewed the literature on this subject. METHODS During a period of 28 months (September 2015-January 2018) 7 women presenting spontaneous vertebral fractures after denosumab discontinuation were attended in the Rheumatology Department of our centre. We analyzed their clinical characteristics, bone metabolism parameters and evolution and reviewed the literature related to this subject. RESULTS The patients had received denosumab during 24-58 months (median 38), and developed a median of 5 VF per patient at 8-20 months (median 10) since the last dose of denosumab. Only 2 patients presented previous VF, and most (5 patients) received previous bisphosphonate treatment. After VF all restarted antiosteoporotic treatment with no further fractures during follow-up (median 19 months). CONCLUSIONS In this short series, previous bisphosphonate treatment does not seem to be a protective factor for the development of VF. The possible development of VF following discontinuation of denosumab must be taken into account in the clinical practice of physicians and dentists. Nonetheless, further studies are needed to improve the identification of patients at risk and the most adequate sequential treatment options.

Abstract
Parathyroid hormone (PTH) (1-84) improves lumbar spine (LS) areal bone mineral density (aBMD) and trabecular bone score (TBS) in hypoparathyroidism over a 2-year treatment period. Studies in osteoporosis have shown that with PTH(1-34) there is a significant increase in LS aBMD and TBS. In this article, we provide new data comparing the effects of the same form of PTH, namely recombinant human PTH, rhPTH(1-84), on aBMD and TBS in hypoparathyroid and osteoporotic patients over an 18-month treatment period. We studied 19 premenopausal (mean age 45.8 ± 11.8 years) and 16 postmenopausal (71 ± 8.4 years) hypoparathyroid women and 38 women with postmenopausal osteoporosis (71 ± 8.3 years). DXA (hologic) at LS, femoral neck, total hip, and distal one-third radius was assessed. Site-matched LS TBS data were extracted from deidentified spine DXA scans using the TBS iNsight software (version 2.1; Medimaps, Geneva, Switzerland). We observed a significant increase in LS aBMD in premenopausal and postmenopausal hypoparathyroid (3 ± 1.1%, p < 0.02 and 3.1 ± 1.4%, p < 0.05, respectively) and osteoporosis (6.2 ± 1.1%, p < 0.0001) patients after 18 months. There was a significant increase (3 ± 1.5%, p = 0.05) in TBS in premenopausal hypoparathyroid patients. A change in TBS was not observed in either postmenopausal group. One-third radius aBMD significantly declined in postmenopausal hypoparathyroid (-3.6 ± 1.1%, p < 0.01) and osteoporosis (-8 ± 1.4%, p < 0.0001) patients. Overall, there was a significantly greater increase in TBS in premenopausal hypoparathyroid than in osteoporosis patients (p < 0.0001) after adjusting for baseline values, age, BMI, and average daily dose of rhPTH(1-84). Comparing only postmenopausal women, the LS aBMD increase was greater in osteoporotic than hypoparathyroid subjects (p < 0.01). Our results demonstrate that rhPTH(1-84) administered for 18 months increases trabecular aBMD in hypoparathyroidism and postmenopausal osteoporosis with greater gains observed in the subjects with osteoporosis. The data suggest different effects of PTH on bone depending on the baseline skeletal structure, skeletal dynamics, compartments, and menopausal status. © 2018 American Society for Bone and Mineral Research.

Abstract
As osteoporosis therapy options have expanded, and clinical guidelines have begun to embrace the concept of limited treatment courses and “drug holidays,” the choices that physicians must make when initiating, electing to continue, or switching therapies have become more complex. As a result, one of the fundamental issues that must be carefully considered is whether, when, and in what sequence anabolic therapies should be utilized. This review evaluates the current evidence supporting the optimal sequence for the use of anabolic and antiresorptive drugs and assesses the expanding number of clinical trials favoring the initial use of anabolic therapy followed by an antiresorptive agent. This review also explores the evidence suggesting that the effectiveness of anabolic medications are diminished when used in patients that have been previously treated with specific antiresorptive drugs for prolonged periods. Finally, the recent advances in designing combination antiresorptive/anabolic treatment approaches are detailed, with a focus on combined denosumab/teriparatide regimens, which appear to provide the most substantial and clinically relevant skeletal benefits to patients with established osteoporosis. © 2018 The Authors.

Medicine (Baltimore) 2017; 96:e9534. [PMID: 29384970 PMCID: PMC6392516 DOI: 10.1097/md.0000000000009534] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 01/22/2023] Open
Abstract
BACKGROUND According to the mechanisms of action, combination therapy of anabolic and antiresorptive agents may produce more effect for the treatment of osteoporosis. However, the combination therapy of anabolic agents and bisphosphonates reports no benefit and even reduced the anabolic effects of anabolic agents. This study aims to assess the effect of combination therapy of anabolic and nonbisphosphonates antiresorptive agents in adults with osteoporosis. METHODS Medline, EMBASE, and Cochrane Library were searched from January 1, 1980 to November 1, 2017 for randomized controlled trials (RCTs) of adults with osteoporosis treated in combination therapy of anabolic and nonbisphosphonates antiresorptive agents compared with monotherapy of either agent alone. The primary outcome was the incidence of fractures. The secondary outcomes were the bone mineral density (BMD) changes at lumbar spine and total hip. Continuous outcomes were expressed as standardized mean difference (SMD) and 95% confidence interval (CI), while dichotomous outcomes were expressed as risk ratio (RR) and 95% CI. The meta-analysis was performed using a random-effects model. I statistic (I > 50% as a threshold indicates significant heterogeneity) was used to assess the heterogeneity. RESULTS A total of 10 trials with a total of 1042 patients were included. The pooled results showed that the combination therapy demonstrated a significant advantage over a monotherapy in the BMD improvement at the lumbar spine (SMD 1.18; 95% CI, 0.63 to 1.72; I = 93%) and the total hip (SMD 0.89; 95% CI, 0.48 to 1.29; I = 88%) and further reduce the fracture risk (RR, 0.45; 95%CI, 0.21 to 0.94; I = 0%). CONCLUSIONS Low-to-moderate-quality evidence shows that the combination therapy of anabolic and nonbisphosphonates antiresorptive agents is superior to monotherapy in improving the BMD and reducing the fracture risk. However, further high methodological quality studies are needed to determine the antifracture efficacy, cost-effectiveness and safety of this strategy of combination therapy.
