Seizures in activating calcium‐sensing receptor antibodies positive autoimmune hypoparathyroidism and preponderance of steroids therapy: A case report

Abstract A 55‐year‐old female patient presented with generalized tonic–clonic seizures. Laboratory evaluation revealed low calcium (4.9 mg/dl), low PTH (0.9 pg/ml), and positive activating CaSR antibodies. The condition was diagnosed as autoimmune hypoparathyroidism. Calcium and vitamin D supplements did not correct the patient's hypocalcemia. The addition of prednisone to vitamin supplements showed a better response and corrected the hypocalcemia. The patient remained in seizure‐free for one year.
