Factors affecting transperitoneal calcium flux in patients undergoing continuous ambulatory peritoneal dialysis

Continuous ambulatory peritoneal dialysis (CAPD) is now accepted widely as effective dialytic method for end stage renal disease. Abnormality of calcium metabolism is the etiology of renal osteodystrophy (ROD), however metabolic changes are yet obscure in patients on CAPD. In this work, we studied factors affecting transperitoneal calcium flux in forty seven patients. All patients (forty two men and five women) aged 25-67 years (average 47 years) were treated by CAPD for 0.2-5.4 years (average 2.2 years). They were medicated calcium carbonate as a phosphate binder and 1 a-hydroxyvitamin D3(0.25-0.75μg/day). Their serum total calcium level was 9.62±1.28 mg/dl (mean±SD) and albumin level was 3.94±0.44g/dl (mean±SD). Transperitoneal calcium flux was a significant correlation between ultrafiltration volume (UFV) [P
