Bone structural characteristics and response to bisphosphonate treatment in children with Hajdu-Cheney Syndrome.
Conclusions: Increased bone resorption and low cortical thickness are consistent with the effect of activating NOTCH2 mutations, which stimulate osteoclastogenesis. The increase in lumbar spine bone density and radial cortical thickness and density by BP therapy provides evidence of beneficial treatment effects in children with HJCYS.

Treatment patterns and trends in patients dying of prostate cancer in Quebec: a population-based study.
Authors: Dragomir A, Rocha J, Vanhuyse M, Cury FL, Kassouf W, Hu J, Aprikian AG Abstract INTRODUCTION: Since just after the year 2000 in Quebec, the management of metastatic castration-resistant prostate cancer (mcrpc) has evolved considerably, with the inclusion of docetaxel-based chemotherapy, bone-targeted therapies (zoledronic acid and denosumab), and more recently, abiraterone, enzalutamide, and cabazitaxel for docetaxel-refractory patients. In the present study, we aimed to analyze contemporary mcrpc management patterns and therapy utilization trends in Quebec. METHODS: The study cohort consisted of patie...

Chronic treatment with Zoledronic Acid increases inflammatory markers in periodontium of rats
Abstract BackgroundBisphosphonates (BF) rises proinflammatory markers and irreversibly binds to bone. Chronically BF can lead to an inflammatory status and can increase the local oxidative stress in periodontium. Therefore, the objective of this study was evaluated if the chronic infusion of Zoledronic Acid (ZA) increases inflammatory markers in periodontium of rats. Methods and resultsChronically infusion therapy was performed with ZA (0.04, 0.2 or 1 mg/kg or saline) by four doses in over a 70‐day period to analysis periodontium of the first right inferior molar using histologic, histochemical (toluidine blue) and immun...

Efficacy and Safety of Zoledronic Acid for Treatment of Postmenopausal Osteoporosis: A Meta-Analysis of Randomized Controlled Trials
We conducted a meta-analysis based on eligible studies to assess the efficacy and safety of zoledronic acid treatment for postmenopausal women with osteoporosis. PubMed, Web of Science, and Embase were searched for eligible studies that assessed the efficacy of zoledronic acid in the prevention of fractures among postmenopausal women with osteoporosis. The primary outcomes were new vertebral fracture, nonvertebral fracture, and hip fracture. Secondary outcomes were bone mineral density (BMD) and safety outcomes. A fixed-effect or random-effect model was used to pool the estimates according to the heterogeneity among the in...

Drug-Induced Autoimmune Hepatitis following Treatment with Zoledronic Acid
Adverse drug reactions are among the most frequent side effects of synthetic and complementary alternative drugs and represent the premier causes of license revocations and acute liver failure. Drug-induced liver injury can resemble literally any other genuine liver disease and usually responds well to drug dechallenge. However, in some cases autoimmune-like hepatitis can evolve, requiring short- and sometimes long-term immunosuppression. Here, we present the hitherto first case of autoimmune-like hepatitis following treatment with zoledronic acid.Case Rep Gastroenterol 2017;11:440 –445 (Source: Case Reports in Gastroenterology)

Bisphosphonate guidelines for treatment and prevention of myeloma bone disease
Abstract Multiple myeloma (MM) is a haematological malignancy characterised by the clonal proliferation of plasma cells in the bone marrow. More than 80% of patients with MM display evidence of myeloma bone disease (MBD), characterised by the formation of osteolytic lesions throughout the axial and appendicular skeleton. MBD significantly increases the risk of skeletal‐related events such as pathologic fracture, spinal cord compression and hypercalcaemia. MBD is the result of MM plasma cells‐mediated activation of osteoclast activity and suppression of osteoblast activity. Bisphosphonates (BP), pyrophosphate analogues ...

The role of bone-targeted therapies for prostate cancer in 2017
Purpose of review: Bone-targeted agents (BTAs), such as zoledronic acid and denosumab, delay the occurrence of skeletal-related events (SREs) in metastatic prostate cancer (PCa) patients. Recently, several agents, such as abiraterone acetate, enzalutamide and radium-223, were approved for the treatment of metastatic castration-resistant PCa (mCRPC). These agents resulted in improved overall survival (OS), pain control and had positive effects on bone health. Combining BTAs to the newly approved agents demonstrates additional benefits that warrant a review of available evidence looking at appropriate combination therapies a...

Abstract Bone targeted therapies are of increasing importance, not only for bone health in the clinical course of breast cancer, but recently also in the adjuvant setting as preventative, anticancer and prognosis-improving agents. It is well established that women with advanced breast cancer receive bisphosphonates or denosumab to prevent therapy-related osteoporosis. As many as 70% of these patients suffer from bone metastases and receive bone targeted agents in order to prevent skeletal related events (SREs), which are debilitating or diminish the quality of life.

CONCLUSION: To our knowledge, this is the first case of AGIN related to bisphosphonate zoledronate in a kidney transplant patient with consequent acute cellular rejection. In using intravenous zoledronate infusion in a kidney transplant recipient, we should be aware that it could potentially induce acute granulomatous tubulointerstitial nephritis and acute rejection. .

GSE96075 Zoledronic acid inhibits NFAT and IL-2 signaling pathways in regulatory T cells and diminishes their suppressive function in patients with metastatic cancer
Contributors : Shannon Murray ; Dhifaf Sarhan ; Andreas LundqvistSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensIn order to identify the processes altered in T regulatory cells (Treg) by Zoledronic acid (ZA), we examined RNA expression by RNA-seq in Treg treated with and without ZA. We identified gene expression alterations in ZA-treated Treg that were essential to Treg function. (Source: GEO: Gene Expression Omnibus)

Recurrence Factors in Giant Cell Tumors of the Spine.
We examined the rate of local recurrence of spinal GCTs and sought to identify recurrence factors in patients who underwent surgery. METHODS: Between 1995 and 2014, 94 mobile spine GCT patients were treated at our hospital, comprising 43 male and 51 female patients with an average age of 33.4 years. Piecemeal intralesional spondylectomy and total en bloc spondylectomy (TES) were performed. Radiotherapy was suggested for recurrent or residual GCT cases. Since denosumab was not available before 2014 in our country, only interferon and/or zoledronic acid was suggested. RESULTS: Of the 94 patients, four underwent con...
