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.
