Hypercalcemia in patients treated with CAPD

The aim of this study was to examine the frequency of the occurence of hypercalcemia in patients treated with CAPD using solutions with the calcium concentration Ca 1.75 mmol/l and Ca 1.25 mmol/l. The study was performed on 11 patients treated with CAPD and lasted 48 weeks. The patients were treated with the calcium dialysate solutions Ca 1.75 mmol/l for 24 weeks. Then they swiched to Ca 1.25 mmol/l. The study was performed at the begining (0) after 2, 12 and 24 weeks of treatment with each kind of dialysate solutions. The measurements of only total calcium revealed three episodes of hypercalcemia--one in the 12th week and two in the 24th week. While the measurements of ionised calcium were performed we diagnosed 12 episodes of hypercalcemia. Four in each examined period--in the 2nd, 12th, 24th week. We did not observe the episodes of hypercalcemia during the treatment with the dialysate solution Ca 1.25 mmol/l.
