Combination treatment with telitacicept, mycophenolate mofetil and glucocorticoids for immunoglobulin A nephropathy: A case report

Telitacicept reduces B cell activation and abnormal immunoglobulin A (IgA) antibody production by inhibiting the activity of B lymphocyte stimulator (BLyS) and a proliferation-inducing ligand (APRIL), thereby decreasing IgA deposition in the glomeruli and local inflammatory response. This ultimately protects the kidneys from damage. This mechanism suggests that Telitacicept has potential efficacy in the treatment of IgA nephropathy.
