Serum ionized calcium in nephrotic syndrome

Abstract

Serum ionized calcium was measured in 12 patients with nephrotic syndrome and 14 nephrotic patients during clinical remission. All subjects had normal creatinine clearance and were not receiving treatment at the time of study. The mean serum ionized calcium values of the two groups of patients, 1.08 ± 0.10 (SD) mmol/l ultrafiltrate and 1.21 ± 0.10 (SD) mmol/l ultrafiltrate respectively, are significantly lower than the normal mean (1.28 ± 0.06 (SD) mmol/l ultrafiltrate). The mean values of the patients in remission are, however, significantly higher (P
