Association of Distal Renal Tubular Acidosis with Hypercalcemia; Report on Three Cases

Background: Hypercalcemia is an endocrine emergency that should be diagnosed as soon as possible and managed carefully. For better management multiple causes of hypercalcemia must be taken into consideration.Case presentation: We observed three infants with hypercalcemia and distal renal tubular acidosis at the time of diagnosis during 5 years. The patients were referred with severe dehydration and failure to thrive.Conclusion: There was no reason for hypercalcemia found in these patients except distal renal tubular acidosis. So we suggest distal renal tubular acidosis as a cause for hypercalcemia.
