  • Title: Short-term effects of renal transplantation on plasma lipids and lipoprotein lipase in children with congenital nephrosis.
    Author: Antikainen M, Holmberg C, Taskinen MR.
    Journal: Clin Nephrol; 1994 May; 41(5):284-9. PubMed ID: 8050208.
    Abstract:
    Plasma lipoprotein and apoprotein (apo) A-I, A-II and B concentrations and post-heparin plasma lipoprotein lipase (LPL) activity and mass were measured in 13 children with congenital nephrotic syndrome of the Finnish type (CNF) six months after renal transplantation to determine whether the severe lipid abnormalities documented prior to and during peritoneal dialysis would normalize. Plasma total triglyceride decreased by 52% (p < 0.001), VLDL triglyceride by 55% (p < 0.01) and total cholesterol by 17% (p < 0.01). HDL cholesterol increased by 51% (p < 0.001), whereas no significant change was observed in LDL cholesterol. Despite these improvements, plasma lipoprotein concentrations were still abnormal after transplantation. Total (p < 0.01) and VLDL triglyceride (p < 0.05) as well as total (p < 0.01), VLDL (p < 0.01) and LDL cholesterol (p < 0.01) were higher than in control children. HDL cholesterol normalized. Plasma apo A-I and A-II concentrations were normal, but the apo B concentration remained high (p < 0.01). Post-heparin LPL activity and mass were normal (25.0 +/- 9.1 mumol FFA/ml/h and 227.2 +/- 88.4 ng/ml). The mean cyclosporine dose correlated positively with the serum creatinine concentration (r = +0.72, p < 0.01). Positive correlations were also observed between total (r = +0.68, p < 0.05) and VLDL triglyceride (r = +0.62, p < 0.05) and the serum creatinine concentrations. We conclude that renal transplantation substantially improves the triglyceride and cholesterol abnormalities in CNF but significant abnormalities still persist.
