    IgA nephropathy (IgAN) is the most common primary glomerulonephritis, with significant global incidence variation, particularly high in East Asia.

  • 2

    This study compared the efficacy of budesonide EC and telitacicept in reducing proteinuria and maintaining eGFR in patients with IgAN.

  • 3

    Telitacicept showed a greater reduction in proteinuria, especially in patients with mild-to-moderate baseline proteinuria.

  • 4

    Budesonide EC was associated with a higher average eGFR during follow-up, but this significance diminished after propensity score matching.

  • 5

    The findings highlight the need for further prospective studies to validate the comparative effectiveness of these treatments in IgAN.
