Plasma lipoprotein (a) levels in children with minimal lesion nephrotic syndrome.
We studied the plasma lipoprotein (a)[Lp(a)] levels in 31 children with minimal lesion nephrotic syndrome (MLNS) in both stages of acute NS and remission. The mean Lp(a) levels in acute NS were significantly higher than those of the controls. The Lp(a) levels in remission were significantly lower than the Lp(a) levels in acute NS. In addition, the Lp(a) levels in remission were not significantly different from those of the controls. However, there were 5 patients whose Lp(a) levels remained higher than 30 mg/dl (the generally accepted limit for cardiovascular risk) after remission. Two of these 5 patients had Lp(a) levels greater than 40 mg/dl. In these patients apoprotein (a) [apo(a)] phenotypes were of lower molecular weight than those of the other 23 patients whose apo(a) phenotypes were examined. Additional episodes of relapse may put the patient with sustained elevated Lp(a) levels at significant risk for the development of cardiovascular disease in the long term.
