Zhang, Xue published the artcilePlasma galactose-deficient immunoglobulin A1 and loss of kidney function in patients with immunoglobulin A vasculitis nephritis, Computed Properties of 59-23-4, the main research area is human plasma galactose IgA vasculitis nephritis kidney function; IgA nephropathy; IgA vasculitis nephritis; galactose-deficient IgA1; kidney disease progression.
IgA (IgA) vasculitis nephritis (IgAV-N) is the most common secondary IgA nephropathy (IgAN). Many studies have demonstrated that galactose-deficient IgA1 (Gd-IgA1) in the IgA1 hinge region is associated with the development and also progression of primary IgAN. In this study, we aimed to evaluate the roles of Gd-IgA1 in kidney disease progression in a large Chinese cohort of IgAV-N patients. This cohort study enrolled 112 patients with IgAVN, 15 patients with IgA vasculitis (IgAV) without kidney involvement and 108 patients with IgAN. Plasma IgA1 and Gd- IgA1 levels at kidney biopsy were measured by ELISA. The primary endpoint was a 30% decline in estimated glomerular filtration rate or end-stage renal disease or death. The levels of Gd-IgA1 in IgAV-N and IgAN patients were higher than in healthy controls (mean±SD, 302.86±54.93 U/mL vs. 303.16±59.43 U/mL vs. 281.30±43.74 U/mL, resp.; P = 0.047), as well as compared with those with IgAV without kidney involvement (272.65±53.14 U/mL; P = 0.036). After adjusting clin. data, higher levels of Gd-IgA1 were found to be independently associated with a greater risk for kidney failure [hazard ratio (HR)=1.703 per 1 SD, 95% confidence interval (CI) 1.233-2.352; P = 0.001]. Compared with the first Gd-IgA1 quartile group (as reference), the fourth Gd-IgA1 quartile group retained a predictive value for poor renal outcome (HR = 3.740, 95% CI 1.204-11.619; P = 0.023). These data indicate that Gd-IgA1 levels were similarly elevated in adult patients with IgAN and those with IgAV-N. Moreover, increased Gd-IgA1 levels were associated with both the development and progression of IgAV-N, as observed in IgAN.
