A rare cause of hypocalcemia
نویسندگان
چکیده
BACKGROUND Many factors influence serum calcium concentration, but the major determinants of calcium homeostatsis are parathyroid hormone (PTH), vitamin D, the ionized calcium, and phosphate [1]. Therefore, deranged calcium metabolism is often seen in the presence of disordered parathyroid hormone (PTH) and/or vitamin D actions. Among these causes is end-organ resistance to the biological effect of parathyroid hormone. CASE REPORT In this paper, we report a case of a patient who presented with flu like symptoms and incidental finding of hypocalcemia that is consistent with parathyroid hormone resistance. CONCLUSIONS Familial causes of hypocalcemia, although rare, should be thought about after ruling out the other common causes of hypocalcemia.
