Serial Galactose-Deficient IgA1 Levels in Children with IgA Nephropathy and Healthy Controls.

ABSTRACT: Galactose-deficient IgA1 (Gd-IgA1) is a key pathogenic factor for IgA nephropathy (IgAN) and a potential biomarker for the disease. This study examined serial serum Gd-IgA1 levels over 1 year in 13 children with IgAN and 40 healthy children, to determine whether or not serum Gd-IgA1 levels changed over time. Subjects were younger than 18 years of age. Follow-up measurements were scheduled 6 and/or 12 months later. Analysis of variance and regression models for repeated measures were used to estimate group and time effects. Serum Gd-IgA1 level was higher in initial samples for IgAN patients compared to those of healthy children (P < 0.0001). Serum Gd-IgA1 levels did not change over time for healthy controls but increased for IgAN patients (P = 0.001). Serum Gd-IgA1 level was elevated for 9
