Hypocalcemia in a dialysis patient treated with deferasirox for iron overload.
Deferasirox is a new iron chelator approved recently for chelation therapy in iron-overloaded patients. It is considered safe and efficacious in most patients, but has not been tested formally in patients with end-stage renal disease. We report a case of a patient with end-stage renal disease secondary to sickle cell nephropathy who developed recurrent symptomatic hypocalcemia while on therapy and later reexposure with this medication for iron overload from long-term blood transfusions. This is the first case report of this complication with deferasirox therapy in a patient with end-stage renal disease.
