The purpose of this study was to perform a meta-analysis to examine the efficacy and safety of denosumab in postmenopausal women with osteoporosis.Medline, Cochrane Library, EMBASE, and Google Scholar databases were searched until October 30, 2014 using combinations of the following search terms: osteoporosis, postmenopause, postmenopausal, women, denosumab. The primary outcome was bone mineral...

BACKGROUND We compared the activity of denosumab with zoledronic acid for delaying or preventing hypercalcaemia of malignancy (HCM) in patients with advanced cancer and bone metastases or with multiple myeloma. METHODS Patient-level data were combined from two identically designed, randomised, double-blind, active-controlled, phase III trials of advanced cancer patients with breast cancer and...

Osteoblasts, originating from mesenchymal cells, make the receptor activator of the nuclear factor kappa B ligand (RANKL) and osteoprotegerin (OPG) in order to control differentiation of activated osteoclasts, originating from hematopoietic stem cells. When the RANKL binds to the RANK of the pre-osteoclasts or mature osteoclasts, bone resorption increases. On the contrary, when OPG binds to the...

UNLABELLED Osteogenesis imperfecta (OI) is a genetically heterogeneous disease leading to bone fragility. OI-VI is an autosomal-recessive form caused by mutations in SERPINF1. There is experimental evidence suggesting that loss of functional SERPINF1 leads to an activation of osteoclasts via the RANK/RANKL pathway. Patients with OI-VI show a poor response to bisphosphonates. We report on four c...

Bone Health Endocrine treatment with aromatase inhibitors (AIs) is associated with significant bone loss in most of postmenopausal women. Therefore, preventive measures should be undertaken including exercise, vitamin D (800–2000 U/day), reducing alcohol, cessation of smoking and avoiding a body mass index of less than 20 kg/m2. In addition to lifestyle interventions, bisphosphonates (BPs) and ...

Denosumab, a monoclonal antibody to the receptor activator of nuclear factor-κB ligand (RANKL), might be a novel preventative therapy for BRCA1-mutation carriers at high risk of developing breast cancer. Beyond its well-recognized bone-targeted activity impeding osteoclastogenesis, denosumab has been proposed to interfere with the cross-talk between RANKL-producing sensor cells and cancer-initi...

UNLABELLED Parathyroid carcinoma is a rare disease leading to severe hypercalcemia due to hyperparathyroidism. Surgery is the primary treatment option. A more progressive form of the disease is characterized by parathyrotoxicosis, and subsequent hypercalcemia is the most common cause of death. We report a case presenting with severe hypercalcemia due to parathyrotoxicosis from parathyroid carci...

Denosumab is a potent antiresorptive agent used for the treatment of osteoporosis and prevention skeletal-related events in patients with multiple myeloma or bone metastasis from solid tumors. Although denosumab generally seems to be safe well tolerated, denosumab-associated hypocalcemia may occur, majority cases are asymptomatic mild. Underlying malignancy, renal failure, calcium vitamin D def...

Monitoring renal function and adjusting dosing for patients with impaired renal function are not required with denosumab (60 mg every 6 months). However, these patients have an increased risk for developing hypocalcemia. This case report describes a patient with renal impairment who developed severe hypocalcemia after receiving denosumab.

Chondroblastoma is a rare, benign bone tumor that represents 1-2% of all primary bone tumors. Denosumab, a monoclonal antibody, has been demonstrated to inhibit the growth of giant cell tumors. We report a case of recurrent chondroblastoma of the squamous temporal bone that is currently suppressed with denosumab.
