  • Title: Lipoprotein(a) levels and fibrinolytic activity in patients with nephrotic syndrome.
    Author: Hong SY, Yang DH.
    Journal: Nephron; 1995; 69(2):125-30. PubMed ID: 7723892.
    Abstract:
    Recently there has been a renewed interest in the possibility that lipoprotein(a)--Lp(a)--may be important in the pathogenesis of thrombosis-related disease. In nephrotic syndrome, hyperlipidemia is a common finding, and thrombosis is a major complication. With this regard, if Lp(a) levels increase concomitantly with low-density lipoprotein and/or very-low-density lipoprotein levels in nephrotic syndrome, this may be considered a thrombogenic factor. To probe this possibility and to corroborate the relationship between Lp(a) and fibrinolytic profiles, we measured the Lp(a) levels in patients with nephrotic syndrome (n = 43), in patients with chronic glomerulonephritis with less proteinuria than in nephrotic syndrome (n = 28), and in healthy controls (n = 50) and observed the relation between Lp(a) levels and tissue-type plasminogen activator (t-PA) activity, euglobulin fibrinolytic activity, and t-PA antigen. The Lp(a) levels were significantly higher in the patients with nephrotic syndrome as compared with both patients with chronic glomerulonephritis and healthy controls (p < 0.001). There was a direct correlation with serum cholesterol level (r = 0.780; p = 0.0001), triglyceride level (r = 0.445; p = 0.0001), and urine protein level (r = 0.675; p = 0.0001) and a reverse correlation with serum albumin levels (r = 0.566; p = 0.0001). The Lp(a) levels showed a reverse correlation with t-pA activity (r = 0.627; p = 0.0001), total fibrinolytic activity in euglobulin fraction (r = 0.458; p = 0.0001), and t-PA activity divided by the t-PA antigen (r = 0.567; p = 0.0001), but no correlation with t-PA antigen.(ABSTRACT TRUNCATED AT 250 WORDS)
