Abstract
Progression of renal failure, represented by rising serum creatinine concentrations, was correlated with progressive elevation of serum parathyroid hormone (PTH) concentrations in 23 children. A significant linear relationship was established. Despite normal serum Ca concentrations in 11 children receiving maintenance hemodialysis, circulating PTH concentrations were elevated after 6 mo. Progressive deterioration with time occurred in all variables tested, at 6 mo. intervals. These complications were reversible with kidney transplantation or treatment with 0.25-2 .mu.g/day of calcitriol for 4-20 wk.
