Abstract
The efficacy and safety of denosumab for the treatment of immobilization-related hypercalcemia in end-stage renal disease remain uncertain. We describe the case of a hemodialysis patient with immobilization-related hypercalcemia who was successfully treated with denosumab. A 79-year-old man admitted for hemodialysis after sustaining an acute kidney injury developed immobilization-related hypercalcemia due to the impairment resulting from an acute myocardial infarction, acute heart failure, and catheter-related bloodstream infection. After admission, the patient’s corrected serum calcium rose to 12.9 from 8.8 mg/dL. A bisphosphonate (alendronate) was administered, but it was ineffective. Subsequently, treatment with denosumab proved to be effective and his corrected serum calcium level declined to 9.3 mg/dL within 1 week. Hypocalcemia, which is an adverse effect of denosumab, was prevented using active vitamin D and calcium supplementation, and his calcium level stabilized. Thus, our case demonstrates that denosumab is a viable therapeutic option for dialysis patients experiencing immobilization-related hypercalcemia.
