Objective To evaluate the acute effects of different calcium concentration dialysate (1.25 mmol/L, 1.5 mmol/L, 1.75 mmol/L) on calcium balance and intact parathyroid hormone(iPTH) in maintenance hemodialysis(MHD) patients with normal serum tCa, and to provide scientific basis for individualized calcium concentration dialysate formula. Methods Dialysate with different calcium concentration (DCa1.25, DCa1.5, DCa1.75) was used in twelve stable MHD patients. Serum tCa, iCa(normalized to pH 7.4) and iPTH were assessed...

Objective To evaluate the acute effects of different calcium concentration dialysate (1.25 mmol/L, 1.5 mmol/L, 1.75 mmol/L) on calcium balance and intact parathyroid hormone(iPTH) in maintenance hemodialysis(MHD) patients with normal serum tCa, and to provide scientific basis for individualized calcium concentration dialysate formula. Methods Dialysate with different calcium concentration (DCa1.25, DCa1.5, DCa1.75) was used in twelve stable MHD patients. Serum tCa, iCa(normalized to pH 7.4) and iPTH were assessed before and after each dialysis session with different calcium concentration dialysate. The iCa from fresh dialysate, spent dialysate at every 30 minutes interval and final total mixed spent dialysate were examined respectively. Phosphorus removal was also determined. Arterial blood pressure(BP) was measured every 30 minutes during hemodialysis session. Results With the DCa1.25, mean calcium loss was 5.03 mmol, but no significant changes of serum iCa and tCa between pre dialysis and post dialysis were found. Serum iPTH increased from (127.17±89.22)pg/ml to (281.92±244.84)pg/ml significantly (P< 0.05). With the DCa1.5, mean body calcium accumulation was 1.4 mmol, serum iCa and tCa increased significantly (P< 0.01) and iPTH did not change significantly as comparaed to pre dialysis. With the DCa1.75, mean body calcium accumulation was 3.3 mmol, serum iCa and tCa increased significantly (P< 0.01) and iPTH decreased significantly from (167.17±113.88)pg/ml to (80±82.28)pg/ml as comparaed with pre dialysis values(P< 0.01). There was no obvious difference in mean phosphorus removal among DCa1.25, DCa1.5 and DCa1.75. Conclusions Calcium influx from the dialysate to the patients occurred in the MHD patients with normal serum tCa when they were dialyzed with DCa1.75.Such influx leads to hypercalcemia. DCa1.25 may result in calcium efflux from the patients to the dialysate, which is suitable for patients with hypercalcemia or serum tCa in high normal range. DCa1.5 can be used in patients with slight hypocalcemia or serum tCa in low normal range, but if hypercalcemia occurs, it should be replaced by DCa1.25.
