Abstract
Nephrotic patients (33) were studied for Ig[immunoglobulin]G-subclass levels in matched pairs of serum and urinary specimens. Levels in the serum were compared with those found in the sera of non-nephrotic control children and normal adults. Results showed an asymmetric depression in the serum level of certain IgG subclasses in some patients with minimal-change nephrotic syndrome, focal glomerulosclerosis and proliferative glomerulonephritis, indicating that the urinary loss of IgG alone cannot account for the low blood levels of this Ig class in these conditions.
