title: Hypercalcemia-induced upper gastrointestinal bleeding after renal transplantation.
abstract: Hypercalcemia is common in patients after renal transplantation and may stimulate gastrin hypersecretion with associated peptic disease. We report on 2 patients with hypercalcemia and life-threatening gastrointestinal hemorrhage controlled by subtotal parathyroidectomy. Retrospective review of our last 10 patients with gastrointestinal hemorrhage revealed that all of those with normal renal function had elevated serum calcium levels. Because of the increased mortality associated with gastrointestinal hemorrhage in renal transplant patients (43%), patients prone to development of hypercalcemia may benefit from early subtotal parathyroidectomy.
