We investigated serum lipoprotein(a) [Lp(a)] levels in 20 patients with the nephrotic syndrome. Lp(a) levels in the nephrotic syndrome patients were significantly higher than those in a control group (30.4±22.5 vs 10.4±17.7mg/dl). Overall, the serum Lp(a) and lipid levels showed no relationship, but on an individual basis the serum Lp(a) level varied with the serum levels of total cholesterol and low density lipoprotein cholesterol in the nephrotic syndrome patients. Our findings suggest that a decrease in serum albumin led to increased hepatic Lp(a) synthesis. It is well known that thrombotic disease supervenes on hypercoagulability in the nephrotic syndrome, so the determination of Lp(a) levels in these patients may provide information which is useful for preventing thrombotic complications.
