Galactose-deficient IgA1 and the corresponding IgG autoantibodies predict IgA nephropathy progression. | LitMetric

AI Article Synopsis

  • IgA nephropathy (IgAN) is a common kidney disease that can lead to severe outcomes, with a significant number of patients progressing to end-stage renal disease, emphasizing the need for non-invasive diagnostic methods.
  • A study of 91 Czech patients with biopsy-confirmed IgAN found that serum levels of galactose-deficient IgA1 (Gd-IgA1) are significantly linked to kidney function decline and can help predict disease progression.
  • The results suggest that measuring Gd-IgA1 and Gd-IgA1-specific antibodies at diagnosis could improve prognostic capabilities for IgAN, with further research planned on larger, diverse populations to validate these findings.

Article Abstract

Background: IgA nephropathy (IgAN), the most common primary glomerulonephritis worldwide, has serious outcomes with end-stage renal disease developing in 30-50% of patients. The diagnosis requires renal biopsy. Due to its inherent risks, non-invasive approaches are needed.

Methods: We evaluated 91 Czech patients with biopsy-proven IgAN who were assessed at time of diagnosis for estimated glomerular filtration rate (eGFR), proteinuria, microscopic hematuria, and hypertension, and then followed prospectively. Serum samples collected at diagnosis were analyzed for galactose-deficient IgA1 (Gd-IgA1) using new native-IgA1 and established neuraminidase-treated-IgA1 tests, Gd-IgA1-specific IgG autoantibodies, discriminant analysis and logistic regression model assessed correlations with renal function and Oxford classification (MEST score).

Results: Serum levels of native (P <0.005) and neuraminidase-treated (P <0.005) Gd-IgA1 were associated with the rate of eGFR decline. A higher relative degree of galactose deficiency in native serum IgA1 predicted a faster eGFR decline and poor renal survival (P <0.005). However, Gd-IgA1 has not differentiated patients with low vs. high baseline eGFR. Furthermore, patients with high baseline eGFR that was maintained during follow-up were characterized by low serum levels of Gd-IgA1-specific IgG autoantibodies (P = 0.003).

Conclusions: Including levels of native and neuraminidase-treated Gd-IgA1 and Gd-IgA1-specific autoantibodies at diagnosis may aid in the prognostication of disease progression in Czech patients with IgAN. Future tests will assess utility of these biomarkers in larger patients cohorts from geographically distinct areas.
