Association of distal renal tubular acidosis with hypercalcemia; report on three cases

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. 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. 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
