Abstract
Lipoprotein(a) (Lp(a)) has recently been recognized to be a risk factor for coronary heart disease. Lp(a) median values in the absence of renal disease are around 10 mg/dl. Higher levels (greater than or equal to 30 mg/dl) correlate with the occurrence of coronary heart disease, particularly in the presence of elevated cholesterol. We have studied Lp(a) in 76 adults with proteinuria. Fifty had glomerular diseases and 26 non-glomerular diseases, with renal function varying from normal to advanced chronic renal failure. Lp(a) values were shifted to the right, with a median of 21.0 mg/dl, and 25% of patients had values of 30 mg/dl or more. Lp(a) did not correlate with cholesterol, age, lipoprotein subclasses, apoproteins A-I or B-100, albumin, creatinine, or creatinine clearance. Median Lp(a) values did not differ significantly comparing men versus women, or glomerular versus non-glomerular disease. Lp(a) may inhibit fibrinolysis, and is deposited in atherosclerotic lesions. Although the cause of these elevated Lp(a) levels is uncertain, we propose that they contribute to the increased risk of coronary heart disease in the nephrotic syndrome, and may play a role in progressive renal disease.
