Abstract
Since denosumab-associated hypocalcemia occurs infrequently, data on its incidence and risk factors are limited. We aimed to evaluate risk factors and develop a useful score for identifying individuals at risk of denosumab-associated hypocalcemia. In this retrospective cohort, 790 consecutive female patients who received 60 mg denosumab at least once between 2016 and 2017 were analyzed. Based on biochemical records from a large-scale single-center, mild and moderate hypocalcemia were defined as albumin-corrected calcium (cCa) levels < 8.5 and < 8.0 mg/dL (< 2.12 and < 2.0 mmol/L), respectively. Mild and moderate hypocalcemia were observed in 8.2% and 1.0% patients, respectively. Patients who developed mild hypocalcemia had lower baseline cCa (8.9 vs. 9.3 mg/dL and 2.22 vs. 2.32mmo/L) and estimated glomerular filtration rate (75.0 vs. 83.2 mL/min/1.73 m2) and more frequent loop diuretic use (10.8% vs. 4.4%; all p < 0.05). In multivariate analysis, low baseline cCa (OR 1.29; 95% CI 1.20-1.40) and chronic kidney disease (CKD) stages 3b-5 were associated with elevated mild hypocalcemia risk (OR 2.92; 95% CI 1.38-6.20). Loop diuretics use was associated with mild hypocalcemia (OR 2.61; 95% CI 1.11-6.18) by univariate analysis, independent of baseline cCa and CKD stage. A scoring approach identified two risk groups: (1) patients without CKD (eGFR ≥ 45) and cCa < 8.5 mg/dL (2.12 mmol/L) and (2) patients with CKD (eGFR < 45) and cCa < 9.5 mg/dL (2.37 mmol/L).

Abstract
A common complication of end-stage renal disease (ESRD) is mineral and bone disorder. Yet, many anti-osteoporotic drugs are contraindicated in ESRD patients. Denosumab, a monoclonal antibody, does not require renal dose adjustment. However, its use is uncertain due to a lack of safety and efficacy of data in this population. Two hemodialysis patient cases of contrasting responses in parathyroid hormone (PTH) after denosumab administration were observed. Patient 1, a 62-years-old male received denosumab 60 mg at Day 0. His calcium decreased from 8.8 mg/dL to 6.8 mg/dL on Day 30. The PTH level increased from 265 pg/mL to 372 pg/mL after 30 days. Calcium and PTH levels approached normal range after increasing doses of vitamin D/calcium supplements, and calcitriol. Patient 2, a 72-years-old male on hemodialysis also received denosumab 60 mg on Day 0. His baseline calcium and PTH were 9.2 mg/dL and 420 pg/mL, respectively. On Day 30, his calcium level decreased (6.8 mg/dL) but, PTH level drastically increased (>5000 pg/mL). Denosumab commonly causes hypocalcemia and hyperparathyroidism since it inhibits osteoclast activation, reduces calcium release from bone and increases PTH levels as a compensatory mechanism. With a wait-and-watch approach, Patient 2’s levels approached the normal range (calcium 9.6 mg/dL and PTH 274 pg/mL at Day 90).

Abstract
Denosumab is a receptor activator of nuclear factor kappa-B (RANK) ligand inhibitor used in the treatment of osteoporosis. Blockade of RANK ligand prevents osteoclastic resorption of bone, but in doing so impairs the parathyroid hormone (PTH)-driven maintenance of serum calcium. A subsequent elevation of PTH remains active at sites other than bone, potentially lowering serum phosphate by inhibiting proximal tubular reabsorption. We present 2 patients who developed severe, symptomatic hypocalcemia after administration of denosumab. These patients provide an opportunity to describe the clinical course and treatment, including the need to consider a continuous calcium infusion, of severe, symptomatic hypocalcemia caused by denosumab.

Abstract
BACKGROUND Osteoporosis is highly prevalent in the heart and lung transplant population. Given high rates of concurrent renal impairment, there is increasing use of denosumab in this population. However, denosumab may be associated with hypocalcaemia, particularly in patients with chronic kidney disease (CKD). AIM To explore the risk of hypocalcaemia in a heart and lung transplant cohort prescribed denosumab for osteoporosis. METHODS We performed a retrospective database review of all surviving heart and lung transplant patients who had received denosumab for osteoporosis between January 2012 and November 2015. We assessed the rates of hypocalcaemia in this cohort and collected baseline clinical data to determine associated factors. RESULTS Ten patients received denosumab and had laboratory results available within 3 months of the dose. Of these, three patients developed severe (grade 4) hypocalcaemia, while two patients developed mild (grade 1) hypocalcaemia. In comparison to the five patients who remained normocalcaemic, patients with hypocalcaemia had significantly lower baseline mean estimated glomerular filtration rate but similar baseline mean corrected serum calcium. Unexpectedly, patients developing hypocalcaemia had non-significantly higher levels of 25-hydroxyvitamin D and lower baseline doses of prednisone. CONCLUSIONS In heart and lung transplant patients, denosumab should be used judiciously in patients with advanced renal disease due to the risk of hypocalcaemia.

Abstract
Background Most patients with advanced prostate cancer develop bone metastases, which often result in painful and debilitating skeletal-related events. Inhibitors of bone resorption, such as bisphosphonates and denosumab, can each reduce the incidence of skeletal-related events and delay the progression of bone pain. However, these agents are associated with an increased risk of hypocalcaemia, which, although often mild and transient, can be serious and life-threatening. Here we provide practical advice on managing the risk of hypocalcaemia in patients with advanced prostate cancer who are receiving treatment with bone resorption inhibitors. Relevant references for this review were identified through searches of PubMed with the search terms ‘prostate cancer’, ‘bone-targeted agents’, ‘anti-resorptive agents’, ‘bisphosphonates’, ‘zoledronic acid’, ‘denosumab’, ‘hypocalcaemia’, and ‘hypocalcemia’. Additional references were suggested by the authors. Main text Among patients with advanced cancer receiving a bisphosphonate or denosumab, hypocalcaemia occurs most frequently in those with prostate cancer, although it can occur in patients with any tumour type. Consistent with its greater ability to inhibit bone resorption, denosumab has shown superiority in the prevention of skeletal-related events in patients with bone metastases from solid tumours. Consequently, denosumab is more likely to induce hypocalcaemia than the bisphosphonates. Likewise, various bisphosphonates have differing potencies for the inhibition of bone resorption, and thus the risk of hypocalcaemia varies between different bisphosphonates. Other risk factors for the development of hypocalcaemia include the presence of osteoblastic metastases, vitamin D deficiency, and renal insufficiency. Hypocalcaemia can lead to treatment interruption, but it is both preventable and manageable. Serum calcium concentrations should be measured, and any pre-existing hypocalcaemia should be corrected, before starting treatment with inhibitors of bone resorption. Once treatment has started, concomitant administration of calcium and vitamin D supplements is essential. Calcium concentrations should be monitored during treatment with bisphosphonates or denosumab, particularly in patients at high risk of hypocalcaemia. If hypocalcaemia is diagnosed, patients should receive treatment with calcium and vitamin D. Conclusion With preventative strategies and treatment, patients with prostate cancer who are at risk of, or who develop, hypocalcaemia should be able to continue to benefit from treatment with bisphosphonates or denosumab.

Hypocalcemia and bone mineral density changes following denosumab treatment in end-stage renal disease patients: a meta-analysis of observational studies. Osteoporos Int 2018; 29:1737-1745.

Abstract
The incidence of hypocalcemia and bone mineral density (BMD) changes in end-stage renal disease (ESRD) patients on denosumab remains unclear. We performed this meta-analysis to assess the incidence of denosumab-associated hypocalcemia and effects of denosumab on BMD in ESRD patients. A literature search was conducted using MEDLINE, EMBASE, and Cochrane Database from inception through November 2017 to identify studies evaluating incidence of denosumab-associated hypocalcemia and changes in serum calcium, phosphate, alkaline phosphatase (ALP), parathyroid hormone (PTH), and BMD from baseline to post-treatment course of denosumab in ESRD patients. Study results were pooled and analyzed using a random-effect model. The protocol for this meta-analysis is registered with PROSPERO (International Prospective Register of Systematic Reviews; no. CRD42017081074). Six observational studies with a total of 84 ESRD patients were enrolled. The pooled estimated incidence of hypocalcemia during denosumab treatment was 42% (95% CI 29-55%, I2 = 0%). Hypocalcemia occurred approximately 7 to 20 days after the first dose and reached nadir of low calcium levels in the first 2 weeks up to 2 months. However, there were no significant changes in serum calcium or phosphate from baseline to post-treatment course (≥ 3 months after treatment) with mean differences [MDs] of 0.20 mg/dL (95% CI, - 0.30 to 0.69 mg/dL) and - 0.10 mg/dL (95% CI, - 0.70 to 0.49 mg/dL). There were significant reductions in ALP and PTH levels with standardized mean differences (SMDs) of - 0.65 (95% CI - 1.13 to - 0.16) and - 1.89 (95% CI - 3.44 to - 0.34), respectively. There were significant increases in T-scores with MDs of 0.39 (95% CI 0.10 to 0.69) and 0.79 (95% CI 0.60 to 0.98) for lumbar spine and femoral neck, respectively. Our study demonstrates the estimated incidence of denosumab-associated hypocalcemia in dialysis patients of 42%. From baseline to post-treatment course, although there are no differences in serum calcium and phosphate, our findings suggest significant reductions in ALP and PTH and a significant increase in BMD. Currently, denosumab should not be considered as the treatment of choice in ESRD patients until more safety and efficacy data are available.

Abstract
Denosumab, a specific inhibitor of RANK ligand, is a novel therapy for postmenopausal osteoporosis and related disorders. An extensive clinical development program has evaluated the clinical efficacy and safety of denosumab with several thousand patients being followed for up to 10 years. Combined with more than six years of postmarketing experience, these studies provide substantial confidence that denosumab is a convenient and appropriate treatment for patients, including Asians, at high risk for fracture. This review will summarize the clinical development of denosumab and lessons learned since its approval for clinical use in 2010.
