title: Parathyroid hormone plasma level in untreated chronic renal failure and in hemodialyzed patients.
abstract: In 42 untreated patients at various stages of chronic renal failure, plasma level of parathyroid hormone was directly proportional to the degree of renal failure and inversely proportional to the serum calcium level. Plasma parathyroid hormone levels were frequently elevated in 21 patients undergoing regular dialysis treatment, in spite of normal levels of serum total calcium and magnesium. Serum-ionized calcium levels measured in dialyzed patients were usually reduced and inversely correlated with the creatinine levels. Parathyroid hormone levels were correlated with the creatinine levels, but the inverse relationship with ionized calcium was not significant.
