Immunoglobulin A nephropathy (IgAN) on DWN NEPHRO
Date Posted: 11/Dec/2015   Deadline: 11/Dec/2015

Knowledge of the pathophysiology of immunoglobulin A nephropathy (IgAN) has progressed significantly, with this disease being clearly identified as an autoimmune disease with a peculiar autoantigen (galactosedeficient IgA1 [Gd-IgA1]), specific autoantibodies (IgG and IgA1 anti-glycans), and formation followed by mesangial deposition of circulating immune complexes with the involvement of other players, such as mesangial transferrin receptor (TfR), monocyte Fcα receptor (CD89), and glomerular transglutaminase 2 (TG2).

The pathogenesis still requires additional clarifications in order to explain the initiation of the disease and to establish the respective role of genetics, environment, and hazard concordance in the cascade of events/steps.

The clinical application of this new knowledge is spreading slowly and includes possible measurement of serum Gd-IgA1, IgG anti-Gd-IgA1, IgA anti-Gd-IgA1, soluble CD89, and soluble TfR in the urine of patients with IgAN.
