[Treatment of chronic kidney disease in IgA nephropathy]

This article provides an overview of treatment approaches for chronic kidney disease (CKD) in patients with IgA nephropathy (IgAN). IgAN is the most common primary glomerulonephritis and results from an autoimmune reaction to aberrantly glycosylated immunoglobulin A (IgA) antibodies. Although historically considered largely benign, it is now recognized that a significant percentage of patients develop dialysis-dependent kidney disease over the years. Traditional treatments with RAAS inhibitors and newer therapies such as SGLT2 inhibitors, endothelin receptor antagonists, and delayed release, primarily locally acting enteric corticosteroids regarding their role in reducing proteinuria and preserving kidney function are also discussed. Additionally, non-immunosuppressive options and lifestyle modifications are examined for their potential to slow disease progression. Further promising medications are currently in clinical trials, including complement inhibitors and immunomodulators. These emerging therapies offer hope for significantly improving the prognosis of IgAN in the future. By presenting a comprehensive overview of current and potential future treatment strategies, this review aims to provide clinicians with up-to-date information to optimize the management of CKD in patients with IgAN.
