Abstract
UNLABELLED Despite their proven efficacy for secondary fracture prevention, long-term adherence with oral bisphosphonates is poor. INTRODUCTION To compare the effectiveness of two interventions on long-term oral bisphosphonate adherence after an upper extremity fragility fracture. METHODS Community-dwelling participants 50 years or older with upper extremity fragility fractures not previously treated with bisphosphonates were randomized to either a multi-faceted patient and physician educational intervention (the active control arm) vs. a nurse-led case manager (the study arm). Primary outcome was adherence (taking > 80% of prescribed doses) with prescribed oral bisphosphonates at 12 months postfracture between groups; secondary outcomes included rates of primary non-adherence and 24-month adherence. We also compared quality of life between adherent and non-adherent patients. RESULTS By 12 months, adherence with the initially prescribed bisphosphonate was similar (p = 0.96) in both groups: 38/48 (79.2%) in the educational intervention group vs. 66/83 (79.5%) in the case manager arm. By 24 months, adherence rates were 67% (32/48) in the educational intervention group vs. 53% (43/81) in case managed patients (p = 0.13). Primary non-adherence was 6% (11 patients) in the educational intervention group and 12% (21 patients) in the case managed group (p = 0.07). Prior family history of osteoporosis (aOR 2.1, 95% CI 1.0 to 4.4) and being satisfied with current medical care (aOR 2.3, 95% CI 1.1 to 4.8) were associated with better adherence while lower income (aOR 0.2, 95% CI 0.1 to 0.6, for patients with income < $30,000 per annum) was associated with poorer rates of adherence. There were no differences in health-related quality of life scores at baseline or during follow-up between patients who were adherent and those who were not. CONCLUSION While both interventions achieved higher oral bisphosphonate adherence compared to previously reported adherence rates in the general population, primary non-adherence and long-term adherence to bisphosphonates were similar in both arms. Adherence was influenced by family history of osteoporosis, satisfaction with current medical care, and income. TRIAL REGISTRATION ClinicalTrials.gov : NCT01401556.

Abstract
UNLABELLED The efficacy of once-weekly risedronate with and without cholecalciferol in bone mineral density (BMD) in Korean patients with osteoporosis was compared. After 12 months, both spine and hip BMD increased significantly in both groups, but there was no significant difference between two groups. INTRODUCTION This study investigated the efficacy and safety of once-weekly risedronate with and without cholecalciferol in BMD in Korean patients with osteoporosis. METHODS This was a prospective, 12-month, randomized, open-labeled, actively controlled trial involving 41 hospitals. A total of 841 subjects with osteoporosis were randomized to once-weekly risedronate (35 mg) and cholecalciferol (5600 IU) in a single pill (RSD+, n = 642) or once-weekly risedronate (35 mg) alone (RSD, n = 199). BMD was measured via dual-energy X-ray absorptiometry at the lumbar spine and hip, and the serum levels of 25-hydroxy vitamin D (25(OH) D), parathyroid hormone (PTH), and alkaline phosphatase (ALP) were assayed at baseline and after 12 months of treatment. RESULTS After 12 months, the lumbar spine, femoral neck, and total hip BMD increased significantly in both groups; there was no significant difference between two groups. Women in the RSD+ group exhibited significantly increased lumbar spine BMD, and subjects with previous fracture history in the RSD+ group had significantly increased total hip BMD compared with the RSD group. The serum 25(OH) D level increased significantly in the RSD+ group. The serum PTH level decreased in the RSD+ group but increased in the RSD group. The serum ALP level significantly decreased in both groups; there was no significant difference between two groups. CONCLUSIONS A once-weekly pill containing risedronate and cholecalciferol had the equivalent antiresorptive efficacy on BMD compared with risedronate alone and improved 25(OH) D serum levels after 12 months of treatment without significant adverse events in Korean patients with osteoporosis.

Rheumatology international. 2019;(3):569-576
Abstract
Fibrodysplasia ossificans progressiva (FOP), is a rare autosomal dominant connective tissue disease with a prevalence of 1 in 2 million. It is characterized by congenital foot deformities and multiple heterotopic ossifications in fibrous tissue. It usually starts with painful soft tissue swellings occurring with attacks at the ages of three or four. The attacks develop spontaneously or after minor trauma, and gradually turn into heterotopic ossifications that cause joint limitations, growth defects, skeletal deformities and chronic pain. The average life expectancy is forthy, and most of the patients are lost due to pulmonary complications. FOP is often misdiagnosed as fibromatosis, desmoid tumour or cancer, bunion, myositis, arthritis and rheumatic diseases. After clinical suspicion, confirmatory genetic analysis should be used for the diagnosis. The treatment of FOP is currently supportive. An effective, proven method has not yet been established. Herein, we present an 18-year-old female patient with FOP who underwent different treatment modalities in a 5-year period. This case-based review reveals all available treatment approaches with at least 6-month follow-up for FOP in the literature.

Abstract
UNLABELLED In this prospective cohort of 6120 participants aged 50+, nitrogen-bisphosphonates but not non-nitrogen bisphosphonates were associated with a significant 34% mortality risk reduction compared to non-treated propensity score matched controls. These findings open new avenues for research into mechanistic pathways. INTRODUCTION Emerging evidence suggests that bisphosphonates (BP), first-line treatment of osteoporosis, are associated with reduced risks for all-cause mortality. This study aimed to determine the association between different BP types and mortality risk in participants with or without a fracture. METHODS A prospective cohort study of users of different BPs matched to non-users by propensity score (age, gender, co-morbidities, fragility fracture status) and time to starting the BP medication from the population-based Canadian Multicentre Osteoporosis Study from nine Canadian centres followed from 1995 to 2013. Mortality risk for bisphosphonate users vs matched non-users was assessed using pairwise multivariable Cox proportional hazards models. RESULTS There were 2048 women and 308 men on BP and 1970 women and 1794 men who did not receive medication for osteoporosis. The relationship between BP and mortality risk was explored in three separate 1:1 propensity score-matched cohorts of BP users and no treatment (etidronate, n = 599, alendronate, n = 498, and risedronate n = 213). Nitrogen BP (n-BP) (alendronate and risedronate) was associated with lower mortality risks [pairwise HR, 0.66 (95% CI, 0.48-0.91)] while the less potent non-n-BP, etidronate, was not [pairwise HR: 0.89 (95% CI, 0.66-1.20)]. A direct comparison between n-BP and etidronate (n = 340 pairs) also suggested a better survival for n-BP [paired HR, 0.47 (95%CI, (95% CI, 031-0.70)] for n-BP vs. etidronate]. CONCLUSION Compared to no treatment, nitrogen but not non-nitrogen bisphosphonates appear to be associated with better survival.

Bone Health Optimization: Beyond Own the Bone: AOA Critical Issues.
Anderson, PA, Jeray, KJ, Lane, JM, Binkley, NC
The Journal of bone and joint surgery. American volume. 2019;(15):1413-1419
Abstract
Worldwide, osteoporosis management is in crisis because of inadequate delivery of care, competing guidelines, and confusing recommendations. Additionally, patients are not readily accepting the diagnosis of poor bone health and often are noncompliant with treatment recommendations. Secondary fracture prevention, through a program such as Own the Bone, has improved the diagnosis and medical management after a fragility fracture. In patients who undergo elective orthopaedic procedures, osteoporosis is common and adversely affects outcomes. Bone health optimization is the process of bone status assessment, identification and correction of metabolic deficits, and initiation of treatment, when appropriate, for skeletal structural deficits. The principles of bone health optimization are similar to those of secondary fracture prevention and can be initiated by all orthopaedic surgeons. Patients who are ≥50 years of age should be assessed for osteoporosis risk and, if they are in a high-risk group, bone density should be measured. All patients should be counseled to consume adequate vitamin D and calcium and to discontinue use of any toxins (e.g., tobacco products and excessive alcohol consumption). Patients who meet the criteria for pharmaceutical therapy for osteoporosis should consider delaying surgery for a minimum of 3 months, if feasible, and begin medication treatment. Orthopaedic surgeons need to assume a greater role in the care of bone health for our patients.

Abstract
OBJECTIVE Clinical trial results have shown that, in glucocorticoid-treated patients, treatment with denosumab 60 mg subcutaneously once every 6 months (Q6M) increased spine and hip bone mineral density (BMD) at month 12 significantly more than treatment with risedronate 5 mg orally once daily (QD). The present analysis was performed to compare efficacy and characterize safety through month 24. METHODS This phase III study enrolled men and women ≥18 years old who had received ≥7.5 mg daily prednisone or equivalent for <3 months (glucocorticoid-initiating) or for ≥3 months (glucocorticoid-continuing) before screening. All patients <50 years old had a history of osteoporotic fracture. Glucocorticoid-continuing patients ≥50 years old had T scores of -2.0 or less (or -1.0 or less with fracture history). Patients were randomized (1:1) to receive denosumab 60 mg subcutaneously Q6M or risedronate 5 mg orally QD for 24 months, with daily calcium and vitamin D. RESULTS Of 795 patients, 590 (74.2%) completed the study (in the glucocorticoid-initiating group, 109 of 145 patients treated with denosumab and 117 of 145 patients treated with risedronate; in the glucocorticoid-continuing group, 186 of 253 patients treated with denosumab and 178 of 252 patients treated with risedronate). Denosumab was superior to risedronate in increasing lumbar spine and total hip BMD at all time points assessed, among glucocorticoid-initiating patients (24-month lumbar spine: BMD increase of 6.2% versus 1.7%, respectively [P < 0.001]; 24-month total hip: BMD increase of 3.1% versus 0.0% [P < 0.001]) and among glucocorticoid-continuing patients (24-month lumbar spine: BMD increase of 6.4% versus 3.2% [P < 0.001]; 24-month total hip: BMD increase of 2.9% versus 0.5% [P < 0.001]). Adverse events, serious adverse events (including infections), and fractures were similar between treatment groups. CONCLUSION Denosumab was superior to risedronate in terms of increases in spine and hip BMD through month 24, and the safety profile was similar between treatment groups. Denosumab may offer a new osteoporosis treatment option for glucocorticoid-treated patients.

Pharmacological management of osteoporosis in postmenopausal women: The current state of the art.
Gatti, D, Fassio, A
Journal of population therapeutics and clinical pharmacology = Journal de la therapeutique des populations et de la pharmacologie clinique. 2019;(4):e1-e17
Abstract
Osteoporosis is a common disease that increases fracture risk. Fragility fractures bring heavy consequences in terms of mortality and disability, with burdensome health and social costs. In subjects with clinical bone fragility, the first goal is to identify the secondary forms of osteoporosis, especially in young subjects, in males and in patients who recently experienced a fragility fracture. In addition, before considering any sort of treatment, it is fundamental to check for adequate calcium and vitamin D intake, since their deficiency is the most common reason for drug failure.In the last decade of the 20th century, several molecules have been developed and proved to be effective in achieving the true goal of any antiosteoporotic drug: fracture prevention.In this article, we considered the most commonly prescribed antiresorptive drugs (hormonal therapy, bisphosphonates, and denosumab), the anabolic agents (teriparatide), the dual-action drugs (romosozumab), and the drugs characterized by an unclear mechanism of action (strontium ranelate) to provide physicians with useful insights for their clinical practice. We discussed the main criteria for the appropriate choice selection and management of each treatment. Finally, we addressed the current controversies related to treatment discontinuation, sequential, and combination therapy.

Abstract
OBJECTIVE The use of immunosuppressive agents, especially glucocorticoids, are associated with increased risks of bone loss in kidney transplant patients. Denosumab, a potent antiresorptive agent, has been shown to increase bone mineral density (BMD) in patients with CKD. However, its effects on bone metabolism and BMD in kidney transplant patients remain unclear. METHODS A literature search was conducted using MEDLINE, EMBASE, and Cochrane Database from inception through April 2018 to identify studies evaluating denosumab's effect on changes in bone metabolism and BMD from baseline to post-treatment course in kidney transplant patients. Study results were pooled and analyzed utilizing random-effects model. The protocol for this systematic review is registered with PROSPERO (International Prospective Register of Systematic Reviews; no. CRD42018095055). RESULTS Five studies (a clinical trial and four cohort studies) with a total of 162 kidney transplant patients were identified. The majority of patients had a baseline eGFR ≥ 30 mL/min/1.73 m2. After treatment (≥ 6 to 12 months), there were significant increases in BMD with standardized mean differences (SMDs) of 3.26 (95% CI 0.88-5.64) and 1.83 (95% CI 0.43 to 3.22) for lumbar spine and femoral neck, respectively. There were also significant increases in T scores with SMDs of 0.92 (95% CI 0.58 to 1.25) and 1.14 (95% CI 0.17 to 2.10) for lumbar spine and femoral neck, respectively. After treatment, there were no significant changes in serum calcium (Ca) or parathyroid hormone (PTH) from baseline to post-treatment course (≥ 6 months) with mean differences (MDs) of 0.52 (95% CI, - 0.13 to 1.16) mmol/L and - 13.24 (95% CI, - 43.85 to 17.37) ng/L, respectively. The clinical trial data demonstrated more asymptomatic hypocalcemia in the denosumab (12 episodes in 39 patients) than in the control (1 episode in 42 patients) group. From the cohort studies, the pooled incidence of hypocalcemia following denosumab treatment was 1.7% (95% CI 0.4 to 6.6%). All reported hypocalcemic episodes were mild and asymptomatic, but the majority of patients required Ca and vitamin D supplements. CONCLUSION Among kidney transplant patients with good allograft function, denosumab effectively increases BMD and T scores in the lumbar spine and femur neck. From baseline to post-treatment, there are no differences in serum Ca and PTH. However, mild hypocalcemia can occur following denosumab treatment, requiring monitoring and titration of Ca and vitamin D supplements.

Protocol for prospective randomised assessor-blinded pilot study comparing hyperbaric oxygen therapy with PENtoxifylline+TOcopherol± CLOdronate for the management of early osteoradionecrosis of the mandible.
Bulsara, VM, Bulsara, MK, Lewis, E
BMJ open. 2019;(3):e026662
Abstract
INTRODUCTION Osteoradionecrosis (ORN) of the mandible is a painful and debilitating condition occurring after radiotherapy to the head and neck to treat cancer. For decades, hyperbaric oxygen (HBO) has formed the mainstay of the early management of ORN. Literature about the efficacy of HBO is contentious. Recently, Oral and Maxillofacial surgical units in France and UK have trialled a combination of medications to treat ORN, also known as PENTOCLO (PENtoxifylline+TOcopherol±CLOdronate). This regime has shown promising results to date however randomised controlled trials in the area comparing HBO against PENTOCLO are lacking and there are no current trials registered in Europe, UK, Australia and the USA. The purpose of this pilot study is to generate a hypothesis that can be tested in large multi-centre controlled trials. METHODS AND ANALYSIS For this pilot study we will recruit 16 patients who will be randomly allocated to one of either HBO or PENTOCLO. After a 4 week period of uniform 'pre-treatment' medication patients will be commenced on their allocated treatment. Standard follow-up examination, imaging and photographs will be taken and de-identified and then presented to two Oral and Maxillofacial surgeons for allocation of a Notani & Lyons classification score. Data for each patient will be tracked over the 18 months of treatment and follow-up. The results will then be analysed using descriptive statistics and all patients included in an intention to treat analysis. ETHICS AND DISSEMINATION Ethical approval for this study has been granted by the South Metropolitan Health Service HREC (PRN RGS0000001193). Data generated by conducting this study will be uploaded to an open access repository in a de-identified form. Results from this study will be disseminated at national and international conferences as well as peer reviewed medical publications. TRIAL REGISTRATION NUMBER ACTRN12618001099213; Pre-results.
