Lipoproteins and lipoprotein profiles were determined in 96 adult nephrotic patients. The serum cholesterol-serum albumin, serum triglycerides-serum albumin and 24-hour urine protein loss-serum albumin values were all significantly inversely correlated. The serum triglycerides and serum cholesterol levels were not significantly lower in the group of lupus nephrotic patients compared to the nonlupus nephrotics. All lipoprotein types except type I were observed. The lipoprotein types fell into three nearly equal groups--IIa, IIb, and V. Type IV, the most common lipoprotein abnormality in uremic patients, was distinctly uncommon.
