Current Treatments and New Developments in the Management of Glucocorticoid-induced Osteoporosis
AbstractGlucocorticoids (GCs) are often used for improvement of quality of life, particularly in the elderly, but long-term GC use may cause harm; bone loss and fractures are among the most devastating side effects. Fracture risk is particularly high in patients with a severe underlying disease with an urgent need for treatment with high-dose GCs. Moreover, it is important to realize that these patients suffer from an augmented background fracture risk as these patients have a high presence of traditional risk factors for osteoporosis, such as high age, low body mass index (BMI), smoking and relatives with osteoporosis or ...

Preventing and Repairing Myeloma Bone Disease by Combining Conventional Antiresorptive Treatment With a Bone Anabolic Agent in Murine Models
ABSTRACTMultiple myeloma is a plasma cell malignancy, which develops in the bone marrow and frequently leads to severe bone destruction. Current antiresorptive therapies to treat the bone disease do little to repair damaged bone; therefore, new treatment strategies incorporating bone anabolic therapies are urgently required. We hypothesized that combination therapy using the standard of care antiresorptive zoledronic acid (Zol) with a bone anabolic (anti ‐TGFβ/1D11) would be more effective at treating myeloma‐induced bone disease than Zol therapy alone. JJN3 myeloma‐bearing mice (n = 8/group) treat...

Drug repurposing to overcome resistance to various therapies for colorectal cancer.
Abstract Emergence of novel treatment modalities provides effective therapeutic options, apart from conventional cytotoxic chemotherapy, to fight against colorectal cancer. Unfortunately, drug resistance remains a huge challenge in clinics, leading to invariable occurrence of disease progression after treatment initiation. While novel drug development is unfavorable in terms of time frame and costs, drug repurposing is one of the promising strategies to combat resistance. This approach refers to the application of clinically available drugs to treat a different disease. With the well-established safety profile and...

Adjuvant Zoledronic Acid in High-Risk Giant Cell Tumor of Bone: A Multicenter Randomized Phase II Trial.
CONCLUSION: Adjuvant treatment with zoledronic acid did not decrease the recurrence rate of GCTB in this study. The efficacy could not be determined because of the small sample size. Because recurrences, even in the denosumab era, are still an issue, a randomized study exploring the efficacy of zoledronic acid in the adjuvant setting in GCTB is still valid.

Presence and distribution of progerin in HGPS cells is ameliorated by drugs that impact on the mevalonate and mTOR pathways.
Abstract Hutchinson-Gilford progeria syndrome (HGPS) is a rare, premature ageing syndrome in children. HGPS is normally caused by a mutation in the LMNA gene, encoding nuclear lamin A. The classical mutation in HGPS leads to the production of a toxic truncated version of lamin A, progerin, which retains a farnesyl group. Farnesyltransferase inhibitors (FTI), pravastatin and zoledronic acid have been used in clinical trials to target the mevalonate pathway in HGPS patients to inhibit farnesylation of progerin, in order to reduce its toxicity. Some other compounds that have been suggested as treatments include rapam...

The Utility of Prophylactic Zoledronic Acid in Patients Undergoing Lung Transplantation - A Retrospective Analysis
Osteoporosis is prevalent among lung transplant candidates and is exacerbated post-transplant by immunosuppressive therapy (glucocorticoids and calcineurin inhibitors). Osteoporotic fractures are a significant source of morbidity. Low bone mineral density (BMD) is a well-recognised surrogate for fracture risk. Intravenous zoledronic acid (ZA) effectively prevents the former and reduces the latter in post-menopausal osteoporosis. Many groups, ours included, prophylactically treat lung transplant recipients with bisphosphonates to prevent BMD reduction and reduce fracture rates.

Role of Bisphosphonates in Breast Cancer Therapy
Opinion statementBisphosphonates are utilized routinely in breast cancer. In metastatic disease with bone involvement, bisphosphonates prevent or delay skeletal-related events and can improve pain control. Different agents have shown benefit compared with placebo or no treatment. While in unselected patients, comparison between zoledronic acid and pamidronate did not show a significant difference, exploratory analyses showed that in patients with osteolytic lesions or hypercalcemia, zoledronic acid is superior to pamidronate. De-escalating treatment with zoledronic acid from every 4 to every 12 weeks has been shown t...

We investigated the prognostic and predictive role of TILs, macrophages, and HLA class 1 expression after NAC with or without the potentially immune modulating compound zoledronic acid (ZA).MethodsBaseline tumor biopsies from 196 patients in the NEOZOTAC trial were analyzed for CD8 (cytotoxic T-cells), FoxP3 (regulatory T-cells), CD68 (macrophages), and HLA class I (HCA2/HC10) expression by immunohistochemistry and subsequently ...

Tuning of the Radium biodistribution by Dietary Supplements in a CD1 Mice Model
Although 223RaCl2 has been approved for the treatment of bone metastases originating from mCRPC (EMA, FDA and others), further data on 223Ra biodistribution and possible metabolism tuning are needed particularly after the discovery of increased risk of death and fractures due to the interactions of 223Ra with abiraterone, prednisone/prednisolone treatment. Thus we report here the results of biodistribution study with 223RaCl2 applied intravenously to a healthy female CD1 mice fed with various dietary supplements - vitamin D and CaCl2 or with co-treatment with zoledronic acid.

mTOR inhibitor and bone-targeted drugs break the vicious cycle between clear-cell renal carcinoma and osteoclasts in an in vitro co-culture model
Publication date: Available online 27 February 2019Source: Journal of Bone OncologyAuthor(s): Chiara Spadazzi, Federica Recine, Laura Mercatali, Giacomo Miserocchi, Chiara Liverani, Alessandro De Vita, Alberto Bongiovanni, Valentina Fausti, Toni IbrahimAbstractThe skeleton is one of the most common sites of metastatic spread from advanced clear-cell renal carcinoma (ccRCC). Most of the bone lesions observed in RCC patients are classified as osteolytic, causing severe pain and morbidity due to pathological bone destruction. Nowadays, it is well known that cancer induced bone loss in lytic metastasis is caused by the trigger...

Zoledronic acid blocks the interaction between breast cancer cells and regulatory T-cells
Zoledronic acid (ZA), a nitrogen-containing bisphosphonate, inhibits osteoclastogenesis. Emerging evidence suggests that ZA has anti-tumor and anti-metastatic properties for breast cancer cells. In a mouse mod... (Source: BMC Cancer)

Diagnosis and Management of Paget's Disease of Bone in Adults: A Clinical Guideline
ABSTRACTAn evidence ‐based clinical guideline for the diagnosis and management of Paget's disease of bone (PDB) was developed using GRADE methodology, by a Guideline Development Group (GDG) led by the Paget's Association (UK). A systematic review of diagnostic tests and pharmacological and nonpharmacological treatmen t options was conducted that sought to address several key questions of clinical relevance. Twelve recommendations and five conditional recommendations were made, but there was insufficient evidence to address eight of the questions posed. The following recommendations were identified as the most im portant:...

Zoledronic acid inhibits the growth of cancer stem cell derived from cervical cancer cell by attenuating their stemness phenotype and inducing apoptosis and cell cycle arrest through the Erk1/2 and Akt pathways
Zoledronic acid is the most potent osteoclast inhibitor and is widely used for advanced cancer patients with bone metastasis, but its role on cancer stem cells (CSCs) remains unclear. In the present study, we ... (Source: Journal of Experimental and Clinical Cancer Research)
