Abstract
BACKGROUND Antiresorptive treatment is currently used in millions of patients with osteoporosis and cancer worldwide. Early studies of denosumab suggested a small signal in ovarian cancer incidence and emerging data suggest that denosumab stimulates germ cell proliferation in the gonads. This study aims to determine the association between the use of denosumab and the risk of reproductive cancers compared with the use of alendronate. RESEARCH DESIGN AND METHODS Using a cohort study design, we used the Danish nationwide registries to identify a population of subjects ≥50 years of age during 2010-2017 who started denosumab after being on alendronate treatment for at least six months. The cohort was matched 1:2 with patients who had been treated with alendronate alone for at least six months. The risk of reproductive cancers and the risk difference between groups were estimated using the Longitudinal Targeted Maximum Likelihood Estimation (L-TMLE) method. RESULTS We identified 6054 Danish individuals who underwent treatment with denosumab. These individuals were matched with 12,108 receiving alendronate. The absolute risk of reproductive cancer was 1.05 % (95 % CI 0.75-1.34) after three years for denosumab users and was not different 0.03 % (-0.34-0.39) than for alendronate users. In supplemental analyses, there was no increased risk of non-reproductive cancers associated with the use of denosumab (risk difference of 0.54 % (-0.41-1.19). Analysis comparing denosumab users with the general population gave similar results. CONCLUSION There was no difference in the risk of cancer following treatment with denosumab compared to treatment with alendronate assessed after a short follow-up of 3 years.

Abstract
INTRODUCTION Medication-related ear canal osteonecrosis (MRECO) is a growing concern linked to prolonged anti-resorptive medication use. Despite primary care providers being key prescribers of these medications, there is limited information about MRECO in primary care literature. This article presents a case of bisphosphonate-induced osteonecrosis of the external auditory canal (EAC), emphasizing the vital role of primary care providers in identifying this rare yet significant side effect of anti-resorptive medication. MAIN SYMPTOMS AND CLINICAL FINDINGS A 65-year-old female, on long-term alendronic acid for osteoporosis, presented to primary care with a 2-year history of left-sided ear blockage and itchiness. Despite prolonged topical treatment for ear wax, symptoms persisted, leading to an Otolaryngology referral. Microsuction revealed exposed bone in the left EAC. DIAGNOSES, INTERVENTIONS, AND OUTCOMES A computed tomography scan confirmed bony erosion of the left EAC, and in the absence of other osteonecrosis risk factors, bisphosphonate-induced osteonecrosis was diagnosed. Management involved bisphosphonate discontinuation, regular aural toilet, and topical treatment, achieving complete ear canal epithelialisation within 6 months. CONCLUSION MRECO, a rare complication of anti-resorptive therapy, is anticipated to rise with increasing antiresorptive medication use in the ageing population. Unexplained ear symptoms in those with a history of current or prior anti-resorptive therapy should raise clinical concern, prompting evaluation for exposed bone in the EAC. Raising awareness of MRECO among primary care providers is crucial for early diagnosis and timely management.

Abstract
OBJECTIVE To assess the outcomes of several rodent animal models for studying tooth extraction-related medication-related osteonecrosis of the jaw (MRONJ). DESIGN After a search of the databases, 2004 articles were located, and 118 corroborated the inclusion factors (in vivo studies in rodents evaluating tooth extraction as a risk factor for the development of MRONJ). RESULTS Numerous studies attempting to establish an optimal protocol to induce MRONJ were found. Zoledronic acid (ZA) was the most used drug, followed by alendronate (ALN). Even when ZA did not lead to the development of MRONJ, its effect compromised the homeostasis of the bone and soft tissue. The association of other risk factors (dexamethasone, diabetes, and tooth-related inflammatory dental disease) besides tooth extraction also played a role in the development of MRONJ. In addition, studies demonstrated a relationship between cumulative dose and MRONJ. CONCLUSIONS Both ZA and ALN can lead to MRONJ in rodents when equivalent human doses (in osteoporosis or cancer treatment) are used. Local oral risk factors and tooth-related inflammatory dental disease increase the incidence of MRONJ in a tooth extraction-related rodent model.

Abstract
Denosumab discontinuation results in accelerated bone remodeling, decreased bone mineral density (BMD), and an increased risk of multiple vertebral fractures. Bisphosphonates are at least partially effective at inhibiting these consequences but there have been no randomized clinical trials assessing the efficacy of alternative antiresorptives. PURPOSE The aim of this study was to evaluate the comparative efficacy of alendronate and the SERM, raloxifene, in preventing the post-denosumab high-turnover bone loss. METHODS We conducted an open-label randomized controlled trial in which 51 postmenopausal women at increased risk of fracture were randomized with equal probability to receive 12-months of denosumab 60-mg 6-monthly followed by 12-months of either alendronate 70-mg weekly or raloxifene 60-mg daily. Serum bone remodeling markers were measured at 0,6,12,15,18, and 24 and areal BMD of the distal radius, spine, and hip were measured at 0,12,18 and 24 months. RESULTS After denosumab discontinuation, serum markers of bone remodeling remained suppressed when followed by alendronate, but gradually increased to baseline when followed by raloxifene. In the denosumab-to-alendronate group, denosumab-induced BMD gains were maintained at all sites whereas in the denosumab-to-raloxifene group, BMD decreased at the spine by 2.0% (95% CI -3.2 to -0.8, P = 0.003) and at the total hip by 1.2% (-2.1 to -0.4%, P = 0.008), but remained stable at the femoral neck and distal radius and above the original baseline at all sites. The decreases in spine and total hip BMD in the denosumab-to-raloxifene group (but not the femoral neck or distal radius) were significant when compared to the denosumab-to-alendronate group. CONCLUSIONS These results suggest that after one year of denosumab, one year of alendronate is better able to maintain the inhibition of bone remodeling and BMD gains than raloxifene.

Abstract
INTRODUCTION Bisphosphonate-related osteonecrosis of the jaw (BRONJ) have been characterized with the use of oral bisphosphonates in osteoporosis and zoledronate in oncology. Uncertainties remain, though, with the occurrence of BRONJ related to the use of zoledronate in osteoporosis. OBJECTIVES We aimed to estimate the incidence and characterize the risk factors of zoledronate-associated BRONJ in osteoporosis as compared with oral bisphosphonates in real life setting. METHODS Cases of BRONJ associated with zoledronate, alendronate or risedronate were extracted from the French pharmacovigilance database up to 2020. The incidence of BRONJ was estimated as their respective numbers related to cases of BRONJ in patients treated with bisphosphonates for osteoporosis, over the same period, according to the Medic'AM database. RESULTS Between 2011 and 2020, BRONJ incidence with zoledronate was 9.6/100,000 patient-year (PY), significantly higher than with alendronate (5.1/100,000 PY, P<0.001), and risedronate (2.0/100,000 PY, P<0.001). The number of patients treated with bisphosphonates has steadily decreased by 44.5% over 10 years. Meanwhile, the incidence of BRONJ decreased (5.8/100,000 PY in 2011; 1.5/100,000 in 2020), although a rebound was observed in 2018, including 47.6% of BRONJ following denosumab. Apart from classical risk factors, recent dental cares stood out in more than 40% of BRONJ, and zoledronate had a shorter exposure time than oral bisphosphonates. CONCLUSIONS In a real-life setting, our data confirm that zoledronate-associated BRONJ in osteoporosis is scarce, seeming slightly more common compared with oral bisphosphonates. We also raise awareness of dental care guidelines and greater vigilance when using bisphosphonates in patients with previous exposure to denosumab.

Abstract
INTRODUCTION To investigate the differences in the incidence rates of suspected stage 0/1 osteonecrosis of the jaw (ONJ) and incidence risk of relevant clinical findings of suspected stage 0 ONJ between patients treated with sequential therapy comprising weekly teriparatide for 72 weeks followed by alendronate for 48 weeks vs. those who received monotherapy with alendronate for 120 weeks. MATERIALS AND METHODS Suspected stage 0/1 ONJ was defined by non-specific symptoms. Tooth mobility and periodontal symptoms (gingival bleeding, swelling, and/or pain) were selected as clinical findings of suspected stage 0 ONJ. Poisson regression models were applied to calculate the incidence rate ratios of suspected stage 0/1 between the teriparatide group (TG) and alendronate group (AG). Generalized linear models were used to calculate the risk ratios of clinical findings between groups. RESULTS Two hundred and sixty-one participants in the TG and 344 in the AG answered a structured questionnaire on oral health and were included in this study. There were no significant differences between the groups in the incidence rate of suspected stage 0/1 ONJ at both 72 and 120 weeks. The risk ratio of the TG to AG for tooth mobility was 0.34 (95% confidence interval [CI] 0.13-0.88, p = 0.02) at 72 weeks and 0.90 (95% CI 0.40-2.03, p = 0.83) at 120 weeks. The incidence rate of tooth mobility related to periodontal symptoms decreased in the TG and increased in the AG during the study. CONCLUSION Tooth mobility accompanied by clinical periodontal symptoms may be a useful early sign of stage 0 ONJ.

Abstract
BACKGROUND Bisphosphonates inhibit bone resorption in patients with postmenopausal osteoporosis and reduce osteoporotic fracture incidence. Medication-related osteonecrosis of the jaws (MRONJ) and atypical femoral fractures (AFF) are both rare but serious adverse effects of anti-resorptive drugs (ARD) such as bisphosphonates. The most advanced form of MRONJ is termed stage 3 and can lead to severe local sequelae like pathologic mandibular fractures (PMF). This study reports a case of MRONJ-related PMF and AFF with osteomyelitis secondary to bisphosphonate treatment for osteoporosis. CASE REPORT A 63-year-old white woman was diagnosed with PMF related to MRONJ stage 3 during treatment of an AFF with osteomyelitis. She had been treated for postmenopausal osteoporosis with 70 mg of alendronate weekly for 2 years. The PMF was treated by stable internal fixation combined with debridement and sequestrectomy, but further debridement was required and 2 mandibular implants were then removed. Postoperative recovery was uneventful and the mandibular infection was controlled after the second surgery. Three weeks later, she was discharged from the hospital, instructed to discontinue the use of alendronate, and referred for 30 sessions of hyperbaric oxygen therapy. At the 3-year follow-up, the PMF was completely healed without signs of mandibular infection or bone exposure. CONCLUSIONS This report raises awareness of both MRONJ and AFF as possible adverse effects of short-term bisphosphonate therapy for postmenopausal osteoporosis, and highlights the importance of dental and orthopedic follow-ups. It is crucial to emphasize the need for early diagnosis and treatment to prevent MRONJ progression to PMF.

Abstract
Bone disease is highly prevalent in patients with chronic kidney disease (CKD), leading to an increased risk of bone fractures. This is due in part to metabolic acid-induced bone dissolution. Bisphosphonates (BPPs) are a potential treatment for inhibiting bone dissolution; however, there are limited studies observing the use of BPPs on acidotic patients. We aimed to determine efficacy of BPPs on maintaining bone health and pH regulation in acid-exposed mice. Using a diet-induced murine model of metabolic acidosis, we examined bone structure, composition, and mechanics as well as blood gases for three groups: control, acidosis, and acidosis + bisphosphonates (acidosis+BPP). Acidosis was induced for 14 days and alendronate was administered every 3 days for the acidosis+BPP group. The administration of BPP had little to no effect on bone structure, mechanics, and composition of the acidosis bones. However, administration of BPP did cause the mice to develop more severe acidosis than the acidosis only group. Overall, we discovered that BPPs may exacerbate acidosis symptoms by inhibiting the release of buffering ions from bone. Therefore, we propose that BPP administration should be carefully considered for those with CKD and that alkali supplementation could help minimize acidifying effects.

Abstract
PURPOSE To compare the effect of denosumab and alendronate on bone mineral density (BMD) in renal transplant recipients (RTRs) with low bone mass. METHODS Patients were randomized to receive either denosumab subcutaneously (60 mg/6 months), oral alendronate (70 mg/week), or no treatment for 1 year. The three groups were prescribed daily calcium and vitamin D. Primary outcome was BMD assessed at lumbar spine, hip, and radius and measured by dual-energy X-ray absorptiometry (DEXA) at baseline and after 6 and 12 months. Adverse events and laboratory assessments (calcium, phosphate, vitamin D, renal functions, and intact parathyroid hormone) were monitored for all patients. Quality of life was assessed at baseline and after 6 and 12 months for all patients. RESULTS Ninety RTRs were included in the study (30 in each group). Baseline clinical characteristics and BMD values were comparable in the three groups. After 12 months, lumbar spine T-score of patients treated with denosumab and alendronate showed a median increase of 0.5 [95% confidence interval (CI): 0.4-0.6] and 0.5 (95% CI: 0.4-0.8), respectively, and patients in the control group showed a decrease of -0.2 (95% CI: -0.3 to -0.1), p < 0.001. Denosumab and alendronate showed a significant comparable gain in T-scores at hip and radius versus a significant decrease in the control group. Adverse events and laboratory values were similar in the three groups. Both treatments resulted in comparable significant improvement in physical functioning, physical role limitations, vitality, and pain scores. CONCLUSION Denosumab and alendronate showed comparable efficacy in improving BMD at all measured skeletal sites and were safe and well-tolerated, with no serious adverse effects reported in RTRs with low bone mass. The study was registered on ClinicalTrials.gov, number NCT04169698.

Abstract
BACKGROUND/OBJECTIVE This study aims to evaluate ibandronate clinical effectiveness in the prevention of osteoporosis-related vertebral fractures (VFs) and nonvertebral fractures (NVFs) in the treatment of postmenopausal osteoporosis. METHODS This systematic review was conducted in accordance with the Centre for Reviews and Dissemination's guidance and reporting in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement 2020. A literature search was performed in PubMed and EMBASE since their inception until February 7, 2022. Randomized controlled trials (RCTs), meta-analysis, experimental, and observational studies evaluating adult patients treated with ibandronate and assessed to osteoporotic fractures prevention were included. The risk of bias was assessed according to study design. Data were analyzed using descriptive statistics. RESULTS Eight references from 4 RCTs, 7 meta-analyses, and 6 observational studies were included. In RCTs, oral ibandronate was superior to placebo in the prevention of VF. However, the doses were lower than those approved. The meta-analyses confirmed these results and showed that adequate doses of oral ibandronate reduce the risk of NVF compared with insufficient doses. In observational studies, oral ibandronate (in approved doses) reduced the risk of VF compared with no treatment or risedronate or alendronate and the risk of NVF versus risedronate or alendronate; the risk of hip fractures was similar between ibandronate and other oral bisphosphonates. CONCLUSIONS There is strong evidence that ibandronate reduces the risk of VF in postmenopausal osteoporosis. The available evidence further suggests that ibandronate may reduce the risk of NVF versus insufficient doses of ibandronate, as well as risedronate or alendronate.

Abstract
BACKGROUND Cardiovascular effects of osteoporosis medications have recently been highlighted. Although oral and intravenous bisphosphonates are assumed to have similar cardiovascular safety, few head-to-head comparisons exist. The cardiovascular safety of teriparatide is unknown. Aim We conducted a pharmacovigilance safety study of cardiac events using real-life adverse event reports from alendronate, zoledronic acid and teriparatide users. METHODS Adverse drug reactions were obtained from Vigibase, a WHO database of individual case safety reports (ICSRs) from 130 countries (1967-2020). ISCRs for atrial fibrillation (AF), angina pectoris, arteriosclerosis coronary artery (ACA), cardiac arrhythmias, coronary artery disease (CAD), thromboembolic events (TE), ischaemic heart disease (IHD), torsade de pointes/QT prolongation (TDP) associated with alendronate, zoledronic acid and teriparatide use were extracted. Data were included in a disproportionality analysis where the lower end of the 95 % credibility interval for the information component (IC025), showing a statistical association when >0. Head-to-head comparisons of ISCRs were estimated by age-adjusted odds ratios and 95 % confidence intervals. RESULTS 465 episodes of angina, 287 ACA, 13,385 arrhythmias, 792 CAD, 6743 TE, 3264 IHD, 1037 myocardial infarcts, and 3714 TDP events were recorded across 50,365 alendronate, 52,436 zoledronic acid and 137,629 teriparatide users. There was a significant association between alendronate and zoledronate with all outcomes except MI. Teriparatide use was associated with AF, arrythmias and angina only. In head-to-head comparisons, teriparatide use was associated with fewer ACA and CAD events than alendronate and fewer ACA than zoledronic acid. DISCUSSION Osteoporosis medication use is associated with adverse cardiac events, except for MI, and these appear to be more common with oral and intravenous bisphosphonates than teriparatide. Our data do not support differential effects of oral and intravenous bisphosphonates on cardiac events. Mechanisms whereby teriparatide may be cardio-protective warrant further investigation.

Abstract
This systematic review (SR) assessed the use of denosumab (Prolia®) to treat osteoporosis in cancer patients receiving endocrine therapy. Denosumab was found to prevent vertebral fractures and improve bone mineral density in cancer patients with osteoporosis. This is the first SR to assess treating osteoporotic cancer patients with denosumab. PURPOSE This study assessed the effectiveness and safety of denosumab (Prolia®) compared to bisphosphonates (alendronate, ibandronate, risedronate, zoledronate), selective estrogen receptor modulators (SERMs) (bazedoxifene, raloxifene) and placebo for the treatment of osteoporosis in hormone-sensitive cancer patients receiving endocrine therapy (men with prostate cancer [MPC] on hormone ablation therapy [HAT], and women with breast cancer [WBC] on adjuvant aromatase inhibitor therapy [AAIT]). METHODS Systematic literature searches were conducted in three biomedical databases to identify randomized controlled trials (RCTs). Frequentist network meta-analyses and/or pairwise meta-analyses were performed on predetermined outcomes (i.e., vertebral/nonvertebral fractures, bone mineral density [BMD], mortality, treatment-related adverse events [AEs], serious AEs [SAEs], withdrawal due to treatment-related AEs). RESULTS A total of 14 RCTs (15 publications) were included. Denosumab was found to prevent vertebral fractures in cancer patients receiving endocrine therapy, relative to placebo. Similarly, denosumab, zoledronate, and alendronate improved BMD at the femoral neck (FN) and lumbar spine (LS) in MPC on HAT, relative to placebo. Denosumab, ibandronate and risedronate improved BMD at the LS and total hip (TH) in WBC on AAIT, relative to placebo. Denosumab and risedronate improved trochanteric (TRO) BMD in WBC on AAIT, relative to placebo. Similarly, denosumab improved FN BMD in WBC on AAIT. CONCLUSION In MPC on HAT, denosumab (relative to placebo) was effective at preventing vertebral fractures and improving BMD at the FN and LS. Moreover, in WBC on AAIT, denosumab (relative to placebo) improved BMD at the FN, LS, TH, and TRO, as well as prevent vertebral fracture.

Abstract
UNLABELLED In this randomized, controlled trial, sequential therapy with once-weekly subcutaneous injection of teriparatide for 72 weeks, followed by alendronate for 48 weeks resulted in a significantly lower incidence of morphometric vertebral fracture than monotherapy with alendronate for 120 weeks in women with osteoporosis at high risk of fracture. PURPOSE To determine whether the anti-fracture efficacy of sequential therapy with teriparatide, followed by alendronate is superior to that of monotherapy with alendronate, a prospective, randomized, open-label, blinded-endpoint trial was performed. METHODS Japanese women aged at least 75 years were eligible for the study, if they had primary osteoporosis and if they were at high risk of fracture. Patients were randomly assigned (1:1) to receive the sequential therapy (once-weekly subcutaneous injection of teriparatide 56.5 μg for 72 weeks, followed by alendronate for 48 weeks) or monotherapy with alendronate for 120 weeks. The primary endpoint in the final analysis was the incidence of morphometric vertebral fracture during the 120-week follow-up period. RESULTS Between October 2014 and June 2020, 505 patients in the sequential therapy group and 506 in the monotherapy group were enrolled. Of these, 489 and 496, respectively, were included in the main analysis. The incidence of morphometric vertebral fracture during the 120-week follow-up period in the sequential therapy group (64 per 627.5 person-years, annual incidence rate 0.1020) was significantly lower than that in the monotherapy group (126 per 844.2 person-years, annual incidence rate 0.1492), with a rate ratio of 0.69 (95% confidence interval 0.54 to 0.88, P < 0.01). After 72 weeks, no patient had a severe adverse event that was considered related to the study drug. CONCLUSION Once-weekly injection of teriparatide, followed by alendronate resulted in a significantly lower incidence of morphometric vertebral fracture than alendronate monotherapy in women with osteoporosis who were at high risk of fracture.

Abstract
BACKGROUND Glucocorticoid-induced osteoporosis is the most common secondary cause of osteoporosis and the resulting fractures cause significant morbidity. Oral bisphosphonates are currently regarded as first line options on the grounds of their low cost. However, teriparatide has been shown to be superior in its effects on bone mineral density and vertebral fracture risk in glucocorticoid-treated individuals with osteoporosis. We conducted a protocol for systematic review and meta-analysis to assess the effectiveness of alendronate and teriparatide in patients with glucocorticoid-induced osteoporosis. METHODS The study protocol has been registered on international prospective register of systematic review (PROSPERO registration number: CRD42022371561). The procedure of this protocol will be conducted according to the Preferred Reporting Item for Systematic Review and Meta-analysis Protocols guidance. PubMed, EMBASE, MEDLINE, the Cochrane Library, Chinese National Knowledge Infrastructure, Chinese Biomedical Literature Database, Wanfang Database, ClinicalTrials.gov trials registry, and Chinese Clinical Trial Registry will be searched from January 1980 to November 2022. Two authors will assess methodological quality of included studies separately by the Cochrane collaboration's risk of bias tool. We will apply RevMan 5.4 software for statistical analysis. RESULTS This study will provide a high-quality comprehensive evaluation of the efficacy and safety of alendronate and teriparatide for treating patients with glucocorticoid-induced osteoporosis. CONCLUSION The conclusion of our systematic review will provide evidence to judge whether teriparatide is an effective intervention for patients with glucocorticoid-induced osteoporosis.

Abstract
Oral bisphosphonates are a key intervention in the treatment of osteoporosis and in reducing the risk of fragility fractures. Their use is supported by over 3 decades of evidence; however, patient adherence to oral bisphosphonates remains poor in part due to complex dosing instructions and adverse events, including upper gastrointestinal symptoms. This problem has led to the development of novel oral bisphosphonate formulations. Buffered, effervescent alendronate is dissolved in water and so seeks to reduce upper gastro-intestinal adverse events, and gastro-resistant risedronate aims to reduce the complexity of dosing procedure (e.g. fasting prior to consumption) whilst still maintaining the efficacy of fracture risk reduction. Clinical trials and real-world data have been employed to demonstrate some benefits in terms of reduced upper gastro-intestinal adverse events, adherence, persistence and health economic outcomes. This report describes the result of an ESCEO (European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis) expert working group, which explores where oral bisphosphonates sit in current clinical practice guidelines, review their risk-benefit profile and the consequences of poor adherence before exploring novel oral bisphosphonate formulations and their potential clinical and health economic impact. Further research is required but there are signs that these novel, oral bisphosphonate formulations may lead to improved tolerance of oral bisphosphonates and thus, improved adherence and fracture outcomes.

Abstract
The balance between osteoclastic bone resorption and osteoblastic bone formation is ultimately responsible for maintaining a structural and functional skeleton. Despite their strength, bones do break and the main cause of fractures are trauma and decreased bone mineral density as a result of aging and/or pathology that weakens the bone's microarchitecture and subsequently, its material properties. Osteoporosis is a disease marked by increased osteoclast activity and decreased osteoblastic activity tipping the remodeling balance in favor of bone resorption and can be caused by aging, glucocorticoids, disuse and estrogen-deficiency. Ultimately, this leads to brittle and weaker bones which become more prone to trauma or stress-induced fractures. The current treatment for preventing and treating osteoporotic fractures is the use of antiresorptive drugs such as bisphosphonates (BPs) and denosumab, but unfortunately, their long-term use, especially with alendronate and ibandronate, has been associated with increased risk of atypical femoral fractures (AFFs); femoral diaphyseal fractures distal to the lesser trochanter but proximal to the supracondylar flare. The purpose of this review is to examine the information that exists in the literature examining the effects of BPs on fracture repair of long bones in rodent (rat and mouse) models. The focus on rodents stems from the scientific community's unresolved need to develop small animal models to examine the molecular, cellular, tissue and biomechanical mechanisms responsible for the development of AFFs and how best they can be treated.

Abstract
OBJECTIVE We aimed to investigate ocular involvement findings in female osteoporosis patients using oral bisphosphonate (BP). METHODS A total of 51 female osteoporosis patients aged 50-75 years using oral BP for at least one year for the study group and 64 age-matched non-osteoporosis female patients for the control group were included in the study. The BP type and exposure time were noted. The ophthalmic examination findings and measurements of the flare of the patients who received oral BP due to osteoporosis and the controls were evaluated. RESULTS The mean duration of BP use was 3.96 years. In the study group, it was detected four of 51 patients were diagnosed with meibomian gland dysfunction (MGD) (7.8%), seven of 102 eyes had erythematous, irregular, thickened lid margin or telangiectasia around the glandular orifices. There were no pathological findings on fundus examination. The mean value of measurements of the flare (ph/ms) was 7.90±7.96 in the study group, and 5.02±0.81 in the control group. When the mean values were compared, there was a significant difference between the two groups (P=.001). A significant difference was found in the mean value of measurements of the flare between the patients using alendronate, and ibandronate with the control group (P=.001; P=.005, respectively). CONCLUSION Our study showed that the flare in the anterior chamber associated with chronic ocular inflammation can be seen higher rate in patients using oral alendronate, and ibandronate compared to those who do not. Morever it can be said that oral BPs may cause similar ocular side effects like as intravascular BPs.

Abstract
CONTEXT Recent meta-analyses of randomized controlled trials have raised concerns that denosumab might increase the risk of infection. However, data of denosumab on the risk of community-acquired pneumonia are sparse. OBJECTIVE This work aimed to examine the risk of community-acquired pneumonia in individuals receiving denosumab compared to those receiving alendronate. METHODS We conducted a propensity score-matched cohort study with a UK primary care database (IQVIA Medical Research Database). We examined the relation of denosumab to community-acquired pneumonia using a Cox proportional hazard model. The study participants were osteoporotic patients older than 45 years who were initiators of denosumab or alendronate from August 1, 2010, to September 17, 2020. The outcome measure was community-acquired pneumonia. RESULTS Patients treated with denosumab (n = 933) were compared with those treated with alendronate (n = 4652). In the matched population, the mean (SD) age was 77 (11) years, 89% were women, and about half of the study population had a history of major osteoporotic fracture. Over 5 years of follow-up, the incidence of community-acquired pneumonia per 1000 person-years was 72.0 (95% CI, 60.1-85.7) in the denosumab group and 75.1 (95% CI, 69.4-81.2) in the alendronate group. The hazard of community-acquired pneumonia was similar between denosumab and alendronate users (hazard ratio [HR] 0.96; 95% CI, 0.79-1.16). The results remained consistent in a series of sensitivity analyses, with HR ranging from 0.82 (95% CI, 0.65-1.04) to 0.99 (95% CI, 0.81-1.21). CONCLUSION Denosumab does not significantly increase the susceptibility of community-acquired pneumonia and could possibly be safely used for the management of osteoporosis.

Abstract
The inflammatory side effects of bisphosphonates are well-known. We report a case of orbital and ocular inflammation secondary to the use of intravenous zoledronic acid and a case of scleritis secondary to oral alendronate. Bisphosphonate-induced inflammation can present as uveitis, (epi)scleritis, and orbital inflammation. The course is typically self-limiting after cessation of bisphosphonate therapy, but resolution can be further promoted by steroid therapy. The ocular side effects of bisphosphonates should be duly considered.

Abstract
UNLABELLED The aim of this study was to evaluate the risk of acute myocardial infarction in patients taking osteoporosis medication. Patients were taken from the SIDIAP or CPRD database and were matched using propensity scores. Patients with diabetes and chronic kidney disease taking SERMs were at an increased risk. The results favour the cardiovascular safety of alendronate as a first-line choice for osteoporosis treatment. INTRODUCTION This study aims to evaluate the comparative safety of anti-osteoporosis drugs based on the observed risk of acute myocardial infarction while on treatment in a primary care setting. METHODS This is a propensity-matched cohort study and meta-analysis. This study was conducted in two primary care record databases covering UK NHS (CPRD) and Catalan healthcare (SIDIAP) patients during 1995-2014 and 2006-2014, respectively. The outcome was acute myocardial infarction while on treatment. Users of alendronate (reference group) were compared to those of (1) other oral bisphosphonates (OBP), (2) strontium ranelate (SR), and (3) selective oestrogen receptor modulator (SERM), after matching on baseline characteristics (socio-demographics, fracture risk factors, comorbidities, and concomitant drug use) using propensity scores. Multiple imputation was used to handle missing data on confounders and competing risk modelling for the calculation of relative risk (sub-distribution hazard ratios (SHR)) according to therapy. Country-specific data were analysed individually and meta-analysed. RESULTS A 10% increased risk of acute myocardial infarction was found in users of other bisphosphonates as compared to alendronate users within CPRD. The meta-analysis of CPRD and SIDIAP results showed a 9% increased risk in users of other bisphosphonate as compared to alendronate users. Sensitivity analysis showed SERMS users with diabetes and chronic kidney disease were at an elevated risk. CONCLUSIONS This study provides additional data on the risk of acute myocardial infarction in patients receiving osteoporosis treatment. The results favour the cardiovascular safety of alendronate as a first-line choice for osteoporosis treatment.

Abstract
Background Glucocorticoid-induced osteoporosis (GIOP) is the most common secondary osteoporosis, alendronate (ALE) and teriparatide (TPTD) are widely used in the treatment of GIOP. However, which of these two drugs has a better curative effect needs the support of evidence-based medicine. Methods We searched PubMed, Embase, Cochrane Library, Web of Science, and Google Scholar for randomized controlled trials of ALE and TPTD in the treatment of glucocorticoid-induced osteoporosis until February 2022. These patients included in the study took glucocorticoid doses greater than 7.5 mg/d for more than 3 months before treatment with ALE and TPTD. The risk ratio (RR) and its 95% confidence interval (CI) are used as the influence index of discontinuous data, and the standardized mean difference (SMD) and its 95% CI are used as the influence index of continuous data. Results A total of 4102 patients were enrolled in all 5 studies that met the admission criteria. We found that compared with ALE, TPTD could reduce the rate of new vertebral fracture (RR = 0.13, 95% CI: 0.05–0.34, P<0.00001). TPTD increased LS bone mineral density (BMD) (0.53, 95% CI 0.42–0.64, P<0.00001), TH BMD (0.17, 95% CI 0.05–0.28, P = 0.004) and FN BMD (0.17, 95% CI 0.05–0.29, P = 0.006) compared to ALE. However, there was no significant difference in the incidence of non-vertebral fracture and adverse events between the two groups. Conclusions Compared with ALE, TPTD is an effective drug to reduce vertebral fracture risk in patients with GIOP. Furthermore, long-term use of TPTD can increase the bone mineral density of LS, FN, and TH.

Abstract
INTRODUCTION Both teriparatide and alendronate were used in the treatment of osteoporosis after renal transplantation. However, there are few studies comparing their application after renal transplant surgeries. This study was carried out to compare the effect of alendronate and teriparatide on bone mineral density in the treatment of osteoporosis after renal transplantation. METHODS This is a retrospective cohort study of 153 patients who were diagnosed with osteoporosis after receiving renal transplantation, and received either alendronate or teriparatide treatment. The demographic patient information, changes in patients' quality of life, mobility and pain scores, serum biochemical markers and bone density of lumbar spine, hip and femoral neck were measured and compared between groups a year after treatment. RESULTS there were no significant differences between the two groups concerning patient demographics such as age, gender and BMI. After a year of treatment, there were no significant differences between the two groups in biochemical markers such as serum calcium, phosphorus, creatinine and 25-OH Vitamin D (P > .05). BMD of lumbar spine, hip and femoral neck after the treatment was significantly higher in the teriparatide group than alendronate group (P < .05), while the incidence of adverse effects was higher in the teriparatide group than alendronate group (P < .05). CONCLUSION teriparatide can be more effective than the alendronate in the treatment of osteoporosis in renal transplant patients, while having more adverse effects. DOI: 10.52547/ijkd.6475.

Abstract
UNLABELLED In this retrospective cohort study, alendronate use among older osteoporosis patients (age>65 years) with reduced renal function (creatinine clearance<35ml/min) was not associated with significant deterioration in renal function from baseline nor increased incidence of osteoporotic fractures or acute kidney injury, compared with patients conservatively managed with only calcium/vitamin D supplementation. INTRODUCTION Oral bisphosphonates are not recommended in patients with creatinine clearance (CrCl) <35ml/min, although this is not supported by post hoc analyses of pivotal oral bisphosphonate studies. As both osteoporosis and renal insufficiency are more prevalent with advancing age, it is important to determine the safety and efficacy of oral bisphosphonates among these patients. METHODS Patients with CrCl <35ml/min on alendronate (group A, n=98), with CrCl <35ml/min conservatively managed (group B, n=96), and with CrCl ≥35ml/min on alendronate (group C, n=96) were followed up to 22 months. Primary outcomes were mean change in CrCl from baseline in group A compared with groups B and C, respectively. Secondary outcomes were the incidence of osteoporotic fractures and adverse events between groups. RESULTS There was no significant change in CrCl from baseline when comparing group A (-1.53±6.83ml/min) with group B (0.59±5.17ml/min) (p=0.075), and group A with group C (-3.71±7.54ml/min) (p=0.163). There was no significant increase in incidences of osteoporotic fractures in group A compared with group B (adjusted relative risk (aRR) 2.02, 95% confidence interval (CI) 0.64-6.37) and group A compared with group C (aRR 1.15, 95% CI 0.46-2.89). There was no significant difference in incidences of acute kidney injury (AKI) in group A compared with group B (aRR 0.48, 95% CI 0.20-1.12). Although statistically non-significant, there was an increase in AKI incidence in group A compared with group C (RR 7.84, 95% CI 0.98-62.66). CONCLUSION Among patients with CrCl <35ml/min, alendronate therapy was not associated with significant deterioration in renal function from baseline. Although not powered for secondary outcomes, there were no statistically significant differences in osteoporotic fracture or AKI incidence between the groups.

Abstract
Objectives: Bisphosphonates (BPs) are powerful inhibitors of osteoclastogenesis and are used to prevent osteoporotic bone loss and reduce the risk of osteoporotic fracture in patients suffering from postmenopausal osteoporosis. Patients with breast cancer or gynecological malignancies being treated with BPs or those receiving bone-targeted therapy for metastatic prostate cancer are at increased risk of bisphosphonate-related osteonecrosis of the jaw (BRONJ). Although BPs markedly ameliorate osteoporosis, their adverse effects largely limit the clinical application of these drugs. This study focused on providing a deeper understanding of one of the most popular BPs, the alendronate (ALN)-induced perturbation of the bone proteome and microenvironmental pathophysiology. Methods: To understand the molecular mechanisms underlying ALN-induced side-effects, an unbiased and global proteomics approach combined with big data bioinformatics was applied. This was followed by biochemical and functional analyses to determine the clinicopathological mechanisms affected by ALN. Results: The findings from this proteomics study suggest that the RIPK3/Wnt/GSK3/β-catenin signaling pathway is significantly perturbed upon ALN treatment, resulting in abnormal angiogenesis, inflammation, anabolism, remodeling, and mineralization in bone cells in an in vitro cell culture system. Conclusion: Our investigation into potential key signaling mechanisms in response to ALN provides a rational basis for suppressing BP-induced adverse effect and presents various therapeutic strategies.

Abstract
UNLABELLED Oral bisphosphonates are effective medications for the prevention of fractures in people suffering from osteoporosis. They are associated with gastrointestinal adverse reactions the most severe being an esophageal ulcer. It is unclear if oral bisphosphonates have a similar gastrointestinal safety profile in the hospital setting as in the community setting because hospitalized patients are often bedridden which may hinder proper drug administration. INTRODUCTION To evaluate the incidence of upper gastrointestinal symptoms in hospitalized patients taking oral bisphosphonate. METHODS This single-center prospective cohort study included hospitalized adult patients actively taking risedronate or alendronate. Upper gastrointestinal symptoms were actively assessed at the baseline and 1 to 5 h following the administration of the oral bisphosphonate. RESULTS A total of 298 patients were included in the study. The mean age was 64 ± 15 years. During the follow-up period, gastric and esophageal symptoms affected 32 patients (10.7%). Epigastric burning, dysphagia, and regurgitation were reported in 4.4% (n = 13), 3% (n = 9), 2.7 (n = 8), and 2.3% (n = 7) patients, respectively. Heartburn, retro-sternal pain, and odynophagia were observed in 1.7% (n = 5), 1.7% (n = 5), and 0.3% (n = 1) patients. CONCLUSION The incidence of adverse reaction was similar to that reported in community trials. The administration of oral bisphosphonate in hospitalized patients does not represent an additional risk for upper gastrointestinal adverse events. Treatment should be optimized during the hospital stay to improve the pharmacological management of osteoporosis.

Abstract
OBJECTIVE A link has been proposed between glucose homeostasis and bone metabolism. Bisphosphonates are first-line treatment of osteoporosis, and we aimed to investigate whether the risk of developing type 2 diabetes was associated with prior use of alendronate. RESEARCH DESIGN AND METHODS We conducted a population-based nested case-control study through access to all discharge diagnoses (ICD-10 system) from the National Danish Patient Registry along with all redeemed drug prescriptions (ATC classification system) from the Health Service Prescription Registry. All cases with a diagnosis of type 2 diabetes between 2008 and 2018 were matched on sex and age with 3 randomly selected controls by incidence-density sampling. Exposure was defined as ever use of alendronate and further grouped as effective and compliant use. ORs were calculated by conditional logistic regression analysis with adjustment for several confounders and test for trend for dose-response relationship. RESULTS We included 163,588 patients with type 2 diabetes and 490,764 matched control subjects with a mean age of 67 years and 55% male subjects. The odds of developing type 2 diabetes were lower among ever users of alendronate (multiple adjusted OR: 0.64 [95% CI 0.62-0.66]). A test for trend suggested a dose-response relationship between longer effective use of alendronate and lower risk of type 2 diabetes. CONCLUSION These results suggest a possible protective effect of alendronate in a dose-dependent manner against development of type 2 diabetes.

Abstract
AIM Drug-induced ocular inflammation is rare and may be overlooked as a cause of uveitis. The main objective was to describe the causes of drug-induced ocular inflammation. Secondary objectives included uveitis complications and drug rechallenge reactions. METHODS A retrospective chart review at Auckland District Health Board's tertiary uveitis clinic (Auckland, New Zealand) was performed. Participants were identified using the uveitis database, which consists of 2,750 subjects. Fifty eyes of 35 subjects had drug-induced inflammation. RESULTS Drug-induced inflammation occurred in 1.3% of subjects with uveitis. Mean age was 66.8±15.6 years, and 25 subjects (71.4%) were female. Drugs responsible were bisphosphonates (24 subjects, 68.6%), brimonidine (one subject, 2.9%), etanercept (three subjects, 8.6%), immune checkpoint inhibitors (two subjects, 5.7%), BRAF inhibitors (three subjects, 8.6%), EGFR inhibitors (one subject, 2.9%) and allopurinol/perindopril (one subject, 2.9%). In subjects with bisphosphonate inflammation, anterior uveitis occurred in 22 (91.7%) and scleritis in two (8.3%). A positive rechallenge reaction occurred in two subjects with zoledronate and one with alendronate. Uveitis occurred in six subjects (17.1%) treated with cancer drugs including immune checkpoint inhibitors, BRAF inhibitors and EGFR protein kinase inhibitors. Subjects with cancer-drug-induced uveitis were managed with corticosteroids and five subjects were able to continue therapy; in one subject uveitis was uncontrollable and required drug cessation. CONCLUSIONS Ocular inflammation caused by bisphosphonates is usually mild and resolves on medication withdrawal. Uveitis seen in association with newer cancer medications can be more severe, but in most cases it can be managed without medication cessation.

Abstract
BACKGROUND Different bone-modifying agents like bisphosphonates and receptor activator of nuclear factor-kappa B ligand (RANKL)-inhibitors are used as supportive treatment in men with prostate cancer and bone metastases to prevent skeletal-related events (SREs). SREs such as pathologic fractures, spinal cord compression, surgery and radiotherapy to the bone, and hypercalcemia lead to morbidity, a poor performance status, and impaired quality of life. Efficacy and acceptability of the bone-targeted therapy is therefore of high relevance. Until now recommendations in guidelines on which bone-modifying agents should be used are rare and inconsistent. OBJECTIVES To assess the effects of bisphosphonates and RANKL-inhibitors as supportive treatment for prostate cancer patients with bone metastases and to generate a clinically meaningful treatment ranking according to their safety and efficacy using network meta-analysis. SEARCH METHODS We identified studies by electronically searching the bibliographic databases Cochrane Controlled Register of Trials (CENTRAL), MEDLINE, and Embase until 23 March 2020. We searched the Cochrane Library and various trial registries and screened abstracts of conference proceedings and reference lists of identified trials. SELECTION CRITERIA We included randomized controlled trials comparing different bisphosphonates and RANKL-inihibitors with each other or against no further treatment or placebo for men with prostate cancer and bone metastases. We included men with castration-restrictive and castration-sensitive prostate cancer and conducted subgroup analyses according to this criteria. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data and assessed the quality of trials. We defined proportion of participants with pain response and the adverse events renal impairment and osteonecrosis of the jaw (ONJ) as the primary outcomes. Secondary outcomes were SREs in total and each separately (see above), mortality, quality of life, and further adverse events such as grade 3 to 4 adverse events, hypocalcemia, fatigue, diarrhea, and nausea. We conducted network meta-analysis and generated treatment rankings for all outcomes, except quality of life due to insufficient reporting on this outcome. We compiled ranking plots to compare single outcomes of efficacy against outcomes of acceptability of the bone-modifying agents. We assessed the certainty of the evidence for the main outcomes using the GRADE approach. MAIN RESULTS Twenty-five trials fulfilled our inclusion criteria. Twenty-one trials could be considered in the quantitative analysis, of which six bisphosphonates (zoledronic acid, risedronate, pamidronate, alendronate, etidronate, or clodronate) were compared with each other, the RANKL-inhibitor denosumab, or no treatment/placebo. By conducting network meta-analysis we were able to compare all of these reported agents directly and/or indirectly within the network for each outcome. In the abstract only the comparisons of zoledronic acid and denosumab against the main comparator (no treatment/placebo) are described for outcomes that were predefined as most relevant and that also appear in the 'Summary of findings' table. Other results, as well as results of subgroup analyses regarding castration status of participants, are displayed in the Results section of the full text. Treatment with zoledronic acid probably neither reduces nor increases the proportion of participants with pain response when compared to no treatment/placebo (risk ratio (RR) 1.46, 95% confidence interval (CI) 0.93 to 2.32; per 1000 participants 121 more (19 less to 349 more); moderate-certainty evidence; network based on 4 trials including 1013 participants). For this outcome none of the trials reported results for the comparison with denosumab. The adverse event renal impairment probably occurs more often when treated with zoledronic acid compared to treatment/placebo (RR 1.63, 95% CI 1.08 to 2.45; per 1000 participants 78 more (10 more to 180 more); moderate-certainty evidence; network based on 6 trials including 1769 participants). Results for denosumab could not be included for this outcome, since zero events cannot be considered in the network meta-analysis, therefore it does not appear in the ranking. Treatment with denosumab results in increased occurrence of the adverse event ONJ (RR 3.45, 95% CI 1.06 to 11.24; per 1000 participants 30 more (1 more to 125 more); high-certainty evidence; 4 trials, 3006 participants) compared to no treatment/placebo. When comparing zoledronic acid to no treatment/placebo, the confidence intervals include the possibility of benefit or harm, therefore treatment with zoledronic acid probably neither reduces nor increases ONJ (RR 1.88, 95% CI 0.73 to 4.87; per 1000 participants 11 more (3 less to 47 more); moderate-certainty evidence; network based on 4 trials including 3006 participants). Compared to no treatment/placebo, treatment with zoledronic acid (RR 0.84, 95% CI 0.72 to 0.97) and denosumab (RR 0.72, 95% CI 0.54 to 0.96) may result in a reduction of the total number of SREs (per 1000 participants 75 fewer (131 fewer to 14 fewer) and 131 fewer (215 fewer to 19 fewer); both low-certainty evidence; 12 trials, 5240 participants). Treatment with zoledronic acid and denosumab likely neither reduces nor increases mortality when compared to no treatment/placebo (zoledronic acid RR 0.90, 95% CI 0.80 to 1.01; per 1000 participants 48 fewer (97 fewer to 5 more); denosumab RR 0.93, 95% CI 0.77 to 1.11; per 1000 participants 34 fewer (111 fewer to 54 more); both moderate-certainty evidence; 13 trials, 5494 participants). Due to insufficient reporting, no network meta-analysis was possible for the outcome quality of life. One study with 1904 participants comparing zoledronic acid and denosumab showed that more zoledronic acid-treated participants than denosumab-treated participants experienced a greater than or equal to five-point decrease in Functional Assessment of Cancer Therapy-General total scores over a range of 18 months (average relative difference = 6.8%, range -9.4% to 14.6%) or worsening of cancer-related quality of life. AUTHORS' CONCLUSIONS When considering bone-modifying agents as supportive treatment, one has to balance between efficacy and acceptability. Results suggest that Zoledronic acid likely increases both the proportion of participants with pain response, and the proportion of participants experiencing adverse events However, more trials with head-to-head comparisons including all potential agents are needed to draw the whole picture and proof the results of this analysis.

Abstract
INTRODUCTION Older people aged over 75 are more prone to falls because physical functions become deteriorated along with aging, and also fracture risk is strongly correlated with age. We evaluated the effects of anti-osteoporosis agents, eldecalcitol (ELD) and alendronate (ALN) on physical functions by assessing dynamic and static postural balance in aged patients with osteoporosis. MATERIALS AND METHODS A randomized, open-label, controlled clinical trial has been conducted with 124 female patients aged 65 or over with osteoporosis. Patients were randomly assigned to receive either 0.75 μg of ELD once-a-day or 35 mg of ALN once-a-week for 24 weeks. The primary endpoint was the change in a postural balance index, adjusted composite equilibrium score (CES) of sensory organization test (SOT). The SOT equilibrium scores, leg muscle strength, and other physical functions were also evaluated. RESULTS The Adjusted CES increased from baseline by 6.10% in the ELD group and 6.28% in the ALN group. There was no statistically significant difference between the two groups. The static postural balance at fixed platform were maintained in the ELD group, but declined in the ALN group. The dynamic postural balance at swaying platform and knee extension power increased from baseline in both groups. CONCLUSIONS These results suggest that ELD and ALN treatments may each be beneficial to improve postural balance control in older patients with osteoporosis via different mechanisms of action.

Abstract
The efficacy and renal safety of low-dose/high-frequency (LDHF) dosing and high-dose/low-frequency (HDLF) dosing of bisphosphonates (BPs) are comparable in patients with normal kidney function but might be different in patients with late-stage chronic kidney disease (CKD). This study aimed to compare the efficacy and renal safety of two different dosage regimens of a BP, alendronate (ALN), in stage 4 CKD using a rat model. Male, 10-week-old Sprague-Dawley rats were subjected to either 5/6 nephrectomy or sham surgery. The animals received subcutaneous administration of vehicle (daily) or ALN in LDHF dosage regimen (LDHF-ALN: 0.05 mg/kg/day) or HDLF dosage regimen (HDLF-ALN: 0.70 mg/kg/2 weeks). Medications commenced at 20 weeks of age and continued for 10 weeks. Micro-computed tomography, histological analysis, infrared spectroscopic imaging, and serum and urine assays were performed to examine the efficacy and renal safety of the ALN regimens. Both LDHF-ALN and HDLF-ALN increased bone mass, improved micro-structure, and enhanced mechanical properties, without causing further renal impairment in CKD rats. Histologically, however, HDLF-ALN more efficiently suppressed bone turnover, leading to more mineralized trabecular bone, than LDHF-ALN in CKD rats, whereas such differences between LDHF-ALN and HDLF-ALN were not observed in sham rats. Both LDHF-ALN and HDLF-ALN showed therapeutic effects on high bone turnover osteoporosis in CKD stage 4 rats without causing further renal impairment. However, as HDLF-ALN more efficiently suppressed bone turnover than LDHF-ALN in late-stage CKD, HDLF-ALN might be more appropriate than LDHF-ALN for fracture prevention in high bone turnover osteoporosis patients with late-stage CKD.

Abstract
Alendronate was synthesized in 1970s in a search for inhibitors of calcification. Istituto Gentili investigators identified it as a potent inhibitor of bone resorption and obtained a patent covering its use in the treatment of osteoporosis and other disorders of excessive bone resorption in the 1980s. Merck licensed alendronate in 1988 and its pharmaceutical chemists reformulated it as a sodium salt with good solubility in a tablet that reduced its potential for esophageal irritation. Clinical trials proved that it reduced bone turnover, increased BMD and reduced the risk of vertebral fractures in postmenopausal osteoporotic women. Merck sponsored a large clinical trials that won FDA approval for treatment of osteoporosis in postmenopausal women and showed that it reduced the risk of spine and hip fractures. Its approval in the US in 1995 spurred sales of bone densitometers and BMD testing to screen for low bone mineral density and identify osteoporosis. Bone mass measurement was supported by medical society guidelines and reimbursement by Medicare and other insurers in the USA. A 70 mg weekly instead of 10 mg daily dose of alendronate produced the same effect on BMD and biochemical markers of bone remodelling with greater convenience and reduced potential for upper GI adverse events. Consequently, by 2006, about 30 million prescriptions for alendronate were written annually in the U.S. for about 15% of postmenopausal women in the U.S. Thereafter, publicity about rare but concerning atypical femoral fractures (AFF) and osteonecrosis of the jaw (ONJ) along with the expiry of Merck's patent (in 2008) and cessation of their promotion of alendronate, and a decline in use of densitometry led to a steady slide in its use even among patients for whom the benefits of alendronate far outweigh its potential risks. Nevertheless, in 25 years since its regulatory approval, alendronate has undoubtedly prevented millions of fractures world-wide.

Abstract
BACKGROUND Ankylosing spondylitis (AS) is a very tricky orthopedic disorder. If such condition cannot be managed fairly well, it may significantly affect quality of life and even leads to disability among such population. A variety of studies have reported that alendronate is utilized for the treatment of AS. However, their results are still contrary, and no systematic review has addressed on this topic. Thus, this study will systematically assess the efficacy and safety of alendronate for the treatment of patients with AS. METHODS A comprehensive literature search will be performed from the below electronic databases from their commencement to the January 31, 2020 without language and publication status limitations: PubMed, Embase, Cochrane Library, Web of Science, Allied and Complementary Medicine Database, WANGFANG, and China National Knowledge Infrastructure. Only randomized controlled trials focusing on the alendronate for the treatment of patients with AS will be considered for inclusion in this study. Two authors will independently select all identified records, extract essential data from all included studies, and appraise study quality for each eligible trial using Cochrane risk of bias. If any differences occur, another experienced author will be invited to solve them by discussion and a consensus decision will be made. We will implement RevMan 5.3 software to analyze the extracted data. RESULTS This study will summarize high-quality randomized controlled trials to assess the efficacy and safety of alendronate for the treatment of patients with AS through primary outcome of bone densitometry; and secondary outcomes of pain intensity, quality of life, disease activity, functional status, and adverse events. CONCLUSION This study will provide evidence to help determine whether alendronate is an effective and safe management for patient with AS or not. STUDY REGISTRATION INPLASY202040153.

Abstract
Osteocalcin, known as a bone gla protein, is considered a regulator of energy metabolism and behavior in its undercarboxylated form (ucOC). Antiresorptive drugs, such as alendronate, reduce serum level of ucOC. The purpose of the current study was to verify if alendronate might impact on energy metabolism and animal behavior by reducing ucOC level and to find out if the presence of metabolic alterations would further worsen these potential adverse effects. Four groups of male Wistar rats (12 per group) were used: a control group, a group receiving high-fat high-fructose diet (HFHF), a group treated with alendronate, and a group receiving alendronate and HFHF. Alendronate was administered subcutaneously in a dose of 50 mcg/kg thrice weekly. Study duration was 15 weeks. Animals were tested for locomotion, anxiety and spatial memory. Glucose and insulin tolerance tests evaluated the glucose metabolism. Visceral obesity was assessed by the weight of right retroperitoneal fat pads. Concentration of ucOC was measured in the serum. Alendronate reduced serum ucOC concentration, increased fasting blood glucose level, and worsened insulin sensitivity. It did not increase visceral adiposity. Fat index was negatively correlated with ucOC in all animals and in the alendronate-treated rats. Alendronate worsened spatial memory of the animals and ucOC levels correlated positively with their cognitive performance.

Abstract
Effective treatment of juvenile osteoporosis, which is frequently caused by glucocorticoid (GC) therapy, has not been established due to limited data regarding the efficacy and adverse effects of antiresorptive therapies on the growing skeleton. We previously demonstrated that sialic acid-binding immunoglobulin-like lectin 15 (Siglec-15) targeting therapy, which interferes with osteoclast terminal differentiation in the secondary, but not primary, spongiosa, increased bone mass without adverse effects on skeletal growth, whereas bisphosphonate, a first-line treatment for osteoporosis, increased bone mass but impaired long bone growth in healthy growing rats. In the present study, we investigated the efficacy of anti-Siglec-15 neutralizing antibody (Ab) therapy against GC-induced osteoporosis in a growing rat model. GC decreased bone mass and deteriorated mechanical properties of bone, due to a disproportionate increase in bone resorption. Both anti-Siglec-15 Ab and alendronate (ALN) showed protective effects against GC-induced bone loss by suppressing bone resorption, which was more pronounced with anti-Siglec-15 Ab treatment, possibly due to a reduced negative impact on bone formation. ALN induced histological abnormalities in the growth plate and morphological abnormalities in the long bone metaphysis but did not cause significant growth retardation. Conversely, anti-Siglec-15 Ab did not show any negative impact on the growth plate and preserved normal osteoclast and chondroclast function at the primary spongiosa. Taken together, these results suggest that anti-Siglec-15 targeting therapy could be a safe and efficacious prophylactic therapy for GC-induced osteoporosis in juvenile patients.

Abstract
Background and objectives: Bisphosphonates represent selective inhibitors of excess osteoblastic bone resorption that characterizes all osteopathies, targeting osteoclasts and their precursors. Their long-term administration in postmenopausal women suffering from osteoporosis has resulted in neural adverse effects. The current study focuses on the research of possible alterations in the femoral nerve, caused by bisphosphonates. We hypothesized that bisphosphonates, taken orally (per os), may produce degenerative changes to the femoral nerve, affecting lower-limb posture and walking neuronal commands. Materials and Methods: In order to support our hypothesis, femoral nerve specimens were extracted from ten female 12-month-old Wistar rats given 0.05 milligrams (mg) per kilogram (kg) of body weight (b.w.) per week alendronate per os for 13 weeks and from ten female 12-month-old Wistar rats given normal saline that were used as a control group. Specimens were studied using immunohistochemistry for selected antibodies NeuN (Neuronal Nuclear Protein), a protein located within mature, postmitotic neural nucleus, and cytosol and Sox10 (Sex-determining Region Y (SRY) - High-Motility Group (HMG) - box 10). The latter marker is fundamental for myelination of peripheral nerves. Obtained slides were examined under a light microscope. Results: Samples extracted from rats given alendronate were more Sox10 positive compared to samples of the control group, where the marker's expression was not so intense. Both groups were equally NeuN positive. Our results are in agreement with previous studies conducted under a transmission electron microscope. Conclusions: The suggested pathophysiological mechanism linked to histological alterations described above is possibly related to toxic drug effects on Schwann and neuronal cells. Our hypothesis enhances the existing scientific evidence of degenerative changes present on femoral nerve following bisphosphonates administration, indicating a possible relationship between alendronate use and neuronal function.

Abstract
CONTEXT The ACTIVE study demonstrated the antifracture efficacy of abaloparatide in postmenopausal women with osteoporosis. ACTIVExtend demonstrated sustained fracture risk reduction with alendronate in abaloparatide-treated participants from ACTIVE. A direct comparison of the efficacy of abaloparatide and antiresorptive therapies has not been performed. OBJECTIVE The objective of this analysis is to compare the antifracture efficacy of abaloparatide in ACTIVE with that of alendronate in ACTIVExtend. DESIGN In this post hoc analysis, the rate of new vertebral fractures for women in ACTIVExtend (N = 1139) was calculated based on baseline and endpoint radiographs for placebo or abaloparatide in ACTIVE and alendronate in ACTIVExtend. Vertebral fracture rates between abaloparatide and alendronate were compared in a Poisson regression model. Fracture rates for nonvertebral and clinical fractures were compared based on a Poisson model during 18 months of abaloparatide or placebo treatment in ACTIVE and 18 months of alendronate treatment in ACTIVExtend. RESULTS The vertebral fracture rate was lower during abaloparatide treatment in ACTIVE (0.47 fractures/100 patient-years) than alendronate treatment in ACTIVExtend (1.66 fractures/100 patient-years) (relative risk reduction 71%; P = .027). Although the comparisons did not meet statistical significance, after switching from placebo (ACTIVE) to alendronate (ACTIVExtend), the rate of new vertebral fractures decreased from 2.49 to 1.66 fractures per 100 patient-years, and after switching from abaloparatide to alendronate from 0.47 to 0.19 fractures per 100 patient-years. The rates of nonvertebral fractures and clinical fractures were not significantly different. CONCLUSION Initial treatment with abaloparatide may result in greater vertebral fracture reduction compared with alendronate in postmenopausal women with osteoporosis.

Abstract
INTRODUCTION Alendronate sodium is used to reduce the risk of bone fracture in aged osteoporosis patients. However, its side effects should be recognized, especially for those aged patients with one or more basic cardiovascular diseases. PATIENT CONCERNS A 90-year-old and a 75-year-old male patient were admitted to our department. These 2 patients were examined by dual energy X-ray absorptiometry (DXA). DIAGNOSIS Both patients were diagnosed with osteoporosis, they also had history of atrial fibrillation (AF) and had long term use of warfarin. INTERVENTIONS Alendronate sodium was prescribed to the two patients at 70 mg once a week. OUTCOMES The 2 patients had experienced dramatic increase of international normalized ratio (INR) to 4.69∼4.86 within 24 hours and gradual decrease in the next 5 days. Both patients experienced spontaneous ecchymoses and petechiae in the skin at the first 72 hours. CONCLUSION Alendronate sodium can transiently increase the INR over 50%, induce spontaneous ecchymoses and petechiae in the skin of aged male osteoporosis patients with AF who took warfarin. Clinicians should pay enough attention when using alendronate sodium on these kinds of patients and be aware of the consequent potential bleeding risk.

Abstract
Thalassemia, as the most prevalent genetic blood disorder, has many associated comorbidities including low bone mass. We studied the comparative effectiveness of alendronate (AL) and zoledronic acid (ZOL) on bone mass improvement in transfusion-dependent thalassemia (TDT) patients a year after treatment. Three hundred seventy-five TDT patients with low bone mass were enrolled in this study. After a year of treatment with either AL or ZOL, a second bone mineral density (BMD) test was ordered to compare the effectiveness of the two aforementioned drugs. Body mass index (BMI), physical activity, sun exposure, and biochemical laboratory data were also considered as associated factors in this study. The BMD test of both groups was almost the same at the baseline and it increased comparably after a year of treatment with AL and ZOL. However, there was a significant difference in lumbar spine BMD delta Z score between both groups of female patients. ZOL was more effective in increasing the lumbar spine BMD of female patients. The choice of bisphosphonates therapy (oral versus parenteral) should be individually selected by considering patient's preference, compliance and the physician's decision. Given the longer administration interval, and TDT patients' compliance issue, it is justified to recommend ZOL as the drug of choice for patients suffering from low bone mass.

Abstract
UNLABELLED We aimed to determine patients' reasons for continuing alendronate therapy over 5 years by administering a questionnaire. Bone mineral density, fractures, drugs, Charlson comorbidity index, and lifestyle factors were also considered. Education and awareness of the disease appeared highly associated with good alendronate adherence while worsening health status with discontinuation. INTRODUCTION Aim of this study was to investigate patients' reasons for adhering to long-term alendronate therapy (more than 5 years), as data is not available in the current literature regarding the reasons behind long-term adherence. METHODS We studied 204 long-term adherent alendronate users: 65 postmenopausal outpatients still adherent (group C, years on treatment = 8.70 ± 1.31) were compared to 139 age-matched patients who discontinued therapy (group S, years on treatment = 8.64 ± 1.43). We evaluated main biochemical parameters, BMD values, fractures, and Charlson comorbidity index (CCI). A questionnaire was administered to analyze the reasons for long-term adherence. RESULTS There were no significant differences between groups concerning baseline DXA values, number of fractures, and CCI. A higher education level was observed in group C (C 54% vs S 35% of patients, p = 0.001). At the time of interview, there was a significantly higher number of patients with a CCI of two in group S compared to the beginning of treatment (56% vs 43%, p = 0.04), together with a higher number of patients taking more than 3 drugs (22% vs 11%, p = 0.01) compared to basal evaluation. Forty-seven percent of patients reported new diseases during the treatment as the main reason for stopping alendronate. A multivariate, stepwise logistic regression analysis showed that awareness of the disease was highly associated with adherence (OR = 0.20; 95% CI 0.045-0.93, p = 0.04) followed by higher education (OR = 0.526, 95% CI 0.345-0.801, p = 0.003). Worsening of CCI was associated with discontinuation (OR = 2.75, 95% CI 1.033-7.324, p = 0.04). CONCLUSIONS Education and disease awareness are associated with long-term alendronate adherence while competing health problems negatively impact adherence.

Abstract
An ASBMR Task Force recommends a drug holiday for certain women treated for ≥5 years with oral alendronate or ≥3 years with intravenous zoledronic acid, with reassessment 2 to 3 years later. It is not known whether changes in bone mineral density (BMD) or bone turnover markers differ after oral or intravenous therapy. Our goal was to compare changes in BMD and procollagen type I N propeptide (PINP) after oral or intravenous bisphosphonate use. In the Fracture Intervention Trial Long-term Extension (FLEX), women who received a mean 5 years of alendronate were randomized to placebo or continued treatment. In the Health Outcomes and Reduced Incidence with Zoledronic Acid Once Yearly-Pivotal Fracture Trial Extension I (HORIZON-PFT E1), women who received 3 years of zoledronic acid were randomized to placebo or continued treatment. We examined the proportion of participants with BMD loss or PINP gain ≥ least significant change (LSC) and those whose values exceeded a threshold (T-score ≤-2.5 or PINP ≥36.0 ng/mL, a premenopausal median value). After 3 years of placebo, the FLEX group had greater mean total hip BMD decreases (-2.3% versus -1.2% in the HORIZON-PFT E1 group, p < 0.01) and greater rises in PINP (+11.6 ng/mL versus +6.7 ng/mL, p < 0.01). There was a greater proportion of individuals in FLEX with total hip BMD loss and PINP increases that exceeded LSC, and PINP values ≥36.0 ng/mL. In contrast, there were small changes in the proportion of women with femoral neck T-scores ≤-2.5 in both groups. In conclusion, 3 years after bisphosphonate discontinuation, a considerable proportion of former alendronate and zoledronic acid users had meaningful declines in total hip BMD and elevations in PINP. Despite a longer treatment course, alendronate may have a more rapid offset of drug effect than zoledronic acid. © 2018 American Society for Bone and Mineral Research.

Abstract
Objective The incidence of osteoporosis is increasing with the rapid aging of the Japanese population. Bisphosphonates are first-line agents used for the treatment of osteoporosis, but they can cause upper gastrointestinal mucosal injury. This study investigated symptoms and upper gastrointestinal mucosal injury associated with oral bisphosphonates. Methods Symptoms were evaluated using the F-scale questionnaire, and esophageal mucosal injury and gastroduodenal ulceration were assessed by endoscopy. Patients were stratified by the type of bisphosphonate (alendronate, risedronate, or minodronate), treatment schedule (once weekly or every four weeks), and the concomitant use of other medications [antithrombotic agents, nonsteroidal anti-inflammatory drugs (NSAIDs), or acid suppressants]. Patients The subjects included 221 patients treated with oral bisphosphonates for at least one month. Results The median F-scale total score was 4 (0-34), reflux score was 2 (0-20), and the mean dyspepsia score was 2 (0-16). Endoscopy showed esophageal mucosal injury of Grade A or worse (Los Angeles classification) in 22/221 patients (10.0%) and gastroduodenal ulcers in 9 patients (4.1%). The dyspepsia score in patients who took minodronate every four weeks was significantly lower (p<0.05) in comparison to patients who took other bisphosphonates. The dyspepsia score was significantly higher (p<0.05) and mucosal injury was significantly more frequent in patients who also used antithrombotic agents and NSAIDs. Conclusion Symptoms and upper gastrointestinal mucosal damage were not necessarily frequent or severe in patients treated with bisphosphonates. However, the concomitant use of bisphosphonates with antithrombotic agents and NSAIDs increased both symptoms and mucosal injury. The symptoms were milder in patients using minodronate once monthly.

METHODS In Rx-Naïve, women were randomized to daily TPTD for 24 months (Daily; n = 23) or cyclic TPTD for 48 months (3 months on, 3 months off; Cyclic; n = 25). In ALN-Rx, women were randomized to continued ALN plus daily TPTD for 24 months, followed by ALN alone for 24 months (Daily; n = 21) or TPTD for 48 months (3 months on, 3 months off) while ALN was continued (Cyclic; n = 20). BMD (DXA) was measured at spine (LS), total hip (TH) and femoral neck (FN). The primary analysis compared 4 years of cyclic therapy to 2 years of daily therapy in RX-naïve and ALN-RX cohorts. RESULTS In Rx-Naïve, BMD changes at 24 months after Daily TPTD vs. 48 months after Cyclic TPTD were: LS 8.6% vs. 6.9%; TH 2.5% vs. 2.6%, and FN 1.6% vs. 2.2%. None of the BMD changes differed significantly between groups but all changes were significant over time within each group (p < 0.01 except for FN where p = 0.17 Daily; p = 0.09 Cyclic). In ALN-Rx, BMD changes at 24 months after Daily TPTD vs. 48 months after Cyclic TPTD were: LS 7.5% vs. 7.2%; TH 3.8% vs. 4.1%, and FN 3.2% vs. 2.5%. There were no differences between groups but all changes were significant within each group (p < 0.01). CONCLUSION The same cumulative dose of TPTD given cyclically for 4-years, does not increase BMD more than standard daily TPTD over 2-years in either Rx-Naïve or ALN-Rx women.

Abstract
The study evaluates efficacy and safety of recombinant human parathyroid hormone (1-34) [rhPTH (1-34)] and alendronate (ALN) in the treatment of postmenopausal osteoporosis.Totally 65 postmenopausal women with osteoporosis were divided into 2 groups. PTH group received daily subcutaneous injection of rhPTH (1-34), and ALN group were treated orally with ALN per week. Bone mineral density (BMD) of lumbar spine (1-4), femoral neck, and total hip, serum levels of calcium, phosphorus, total cholesterol, triglyceride, alkaline phosphatase (ALP), N-terminal propeptide of type I collagen (PINP), and C-telopeptide of type I collagen (CTX) were tested before treatment and at week 24 and 48 after treatment. Serum levels of vascular endothelial growth factor (VEGF) and platelet-derived growth factor-BB (PDGF-BB) were measured before treatment and at week 48 after treatment.The rhPTH (1-34) increased BMD of lumbar spine (1-4), but decreased BMD of femoral neck and total hip at week 48 after treatment. By contrast, ALN enhanced BMD of lumbar spine (1-4) and femoral neck, but reduced BMD of total hip at week 48 after treatment. In PTH group, serum levels of PINP, ALP, and β-CTX were significantly elevated above baseline at week 24 and 48 after treatment. Treatment with ALN decreased levels of PINP, ALP, and β-CTX compared with baseline at week 24 and 48 after treatment. rhPTH (1-34) and ALN significantly decreased levels of PDGF-BB, but not levels of VEGF. rhPTH (1-34) increased levels of calcium, phosphorus and triglyceride, but decreased levels of total cholesterol. ALN increased levels of calcium and triglyceride, but reduced levels of phosphorus and total cholesterol. rhPTH (1-34) and ALN were safe in the treatment of postmenopausal osteoporosis.The study demonstrates that efficacy of rhPTH (1-34) on BMD of lumbar spine (1-4) is similar to that of alendronate in the treatment of postmenopausal osteoporosis. The effect of rhPTH (1-34) on BMD of femoral neck or total hip is weaker than that of ALN. In addition, rhPTH (1-34) increases BMD of lumbar spine (1-4) maybe by raising serum levels of VEGF, but reduces BMD of femoral neck and total hip maybe by decreasing serum levels of PDGF-BB.

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

Abstract
BACKGROUND Vitamin D (VD) insufficiency or deficiency is a frequent comorbidity in Chinese women with postmenopausal osteoporosis (PMO). The present study aimed to investigate 25-hydroxyvitamin D [25(OH) D] improvement and calcium-phosphate metabolism in Chinese PMO patients treated with 70 mg of alendronate sodium and 5600 IU of vitamin D3 (ALN/D5600). METHODS Chinese PMO women (n = 219) were treated with 12-month ALN/D5600 (n = 111) or calcitriol (n = 108). Changes in 25(OH) D at month 12 were post hoc analyzed by the baseline 25 (OH) D status using the longitudinal analysis. The main safety outcome measures included serum calcium and phosphate and 24-h urine calcium, and the repeated measures mixed model was used to assess the frequencies of the calcium-phosphate metabolic disorders. RESULTS Absolute change in mean serum 25(OH) D level was the greatest in VD-deficient patients and least in VD-sufficient patients at months six and 12 (both, P < 0.01). Serum calcium level remained significantly lower in the ALN/D5600 treatment group than in the calcitriol treatment group throughout the 12 months. Mean 24-h urine calcium slightly increased in the ALN/D5600 treatment group and significantly increased in the calcitriol treatment group (+ 1.1 and + 0.9 mmol/L at months six and 12; both, P < 0.05). Calcitriol treatment was associated with more frequent hypercalciuria at month six (9.4% vs. 18.5%, P = 0.05), but not at month 12 (12.3% vs. 13.0%). CONCLUSION Baseline VD status predicted 25(OH) D improvement in PMO patients on 12-month ALN/D5600 treatment. The daily use of 0.25 μg of calcitriol was associated with more frequent hypercalciuria at month six, compared to ALN/5600 treatment, necessitating the safety re-evaluation of calcitriol at a higher dosage.

Abstract
Bisphosphonates (BP) are inhibitors of bone resorption and are used to treat postmenopausal osteoporosis. Long-term treatment with BP attenuates bone remodeling, possibly leading to detrimental consequences for the bones' ability to repair defects. To test this hypothesis, an animal model was established. Twelve week old mice were ovariectomized (OVX). Following confirmation of bone loss 8 weeks after OVX, the animals were treated with Alendronate (ALN) until sacrifice. After 5 weeks of ALN injections, the femoral bones were osteotomized and the osteotomies were either rigidly or non-rigidly stabilized. In rigidly fixed defects, no callus developed between 1 and 5 weeks after osteotomy, whereas after non-rigid fixation, callus development occurred. The administration of ALN resulted in an increase in newly formed bone at the defect site 5 weeks after osteotomy, irrespective of the estrogen status or fixation system. Transcriptome analysis demonstrated that both rigid and non-rigid fixation affected gene expression primarily during the middle phase of bone repair. Furthermore, the number of differentially expressed genes in tissues from non-rigidly fixed defect sites increased in animals treated with ALN over the course of bone repair. This indicates that ALN-dependent repair processes become increasingly dominant in the late phases of the healing process. Ranking of the factors affecting the composition of the transcriptome and their impact on the healing process revealed fixation at the defect site to be the strongest causative factor, followed by bisphosphonate treatment and estrogen deficiency. The present study suggests that the continuous administration of ALN is detrimental to bone repair, eventually causing a delay in healing in mechanically compromised situations. Consequently, rigid fixation may prove essential for a successful intervention.
