CASE REPORT- VITAMIN D TOXICITY CAUSING ACUTE KIDNEY INJURY

THIRUMURUGAN S

Abstract


Vitamin D overdose is one of the important causes of hypercalcemia. We report our
patient, a weight lifter who presented with abdominal pain and constipation. Investigations revealed
renal failure, hypercalcemia, hypervitaminosis D and low paratharmone level. Detailed history
revealed intake of high dose of parenteral vitamin D during the previous 2 months. Renal biopsy
showed acute tubular injury and calcium concretions. Patient was treated with intravenous saline and
furosemide. He improved well with treatment and laboratory parameters became normal over three
months. Hypervitaminosis D should be considered in the differential diagnosis of hypercalcemia and
acute tubular injury.
