Abstract
BACKGROUND
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.
CASE SUMMARY
We present the case of a 24-year-old female who was diagnosed with IgA nephropathy due to significant proteinuria and mild renal impairment. Pathologically, she exhibited focal proliferative glomerulonephritis. Treatment with angiotensin II receptor blocker, hormones, and mycophenolate mofetil did not lead to a significant improvement in her condition. However, upon the addition of telitacicept, the patient’s renal function recovered and her proteinuria rapidly reduced. Hormones were swiftly tapered and discontinued, with no occurrence of severe infections or related complications.
CONCLUSION
Telitacicept combined with hormones and mycophenolate mofetil may be a safe and effective induction therapy for IgA nephropathy.
Core Tip: Telitacicept reduces B cell activation and abnormal immunoglobulin A (IgA) antibody production by inhibiting the activity of B lymphocyte stimulator and a proliferation-inducing ligand, thereby decreasing IgA deposition in the glomeruli and local inflammatory response. This mechanism suggests that Telitacicept has potential efficacy in the treatment of IgA nephropathy. This paper reports a successful clinical case of using Telitacetin to treat IgA nephropathy.
