title: Hypercholesterolemia and glomerular diseases in urinary screening of school children.
abstract: Although hypercholesterolemia frequently accompanies nephrotic syndrome, high serum total cholesterol (TC) levels are occasionally seen in children with non-nephrotic glomerular diseases. However, little is known of the significance, if any, of these elevated serum TC levels in non-nephrotic glomerular diseases. During the past 5 years, a total of 256,179 school children received yearly urinary screening at school for renal diseases and 1,702 children (0.66% of the total, although 174 children dropped out) had proteinuria and/or hematuria. Using the data obtained from the 1,528 children, we studied whether there is any association between serum TC levels and the presence of glomerular diseases. The detection rate of glomerular diseases (IgA nephropathy, membranoproliferative glomerulonephritis, focal segmental glomerular sclerosis, etc.) in the subjects with high serum TC levels (> or =200 mg/dl) was significantly higher (16 of 161, 9.94%, P<0.001) than in those with normal serum TC levels (<200 mg/dl) (10 of 1,367, 0.73%). There were no significant differences in serum albumin and blood urea nitrogen levels between the two groups. We conclude that children with chance proteinuria and/or hematuria may be at higher risk for glomerulonephritis of various types when they have unexplained hypercholesterolemia, and that measurement of serum cholesterol levels may be useful in urinary screening for renal diseases.
