泰它西普在风湿病和自身免疫病中的应用研究进展OA

Traditional treatment regimens for rheumatism and autoimmune diseases are associated with significant adverse effects,and some patients have a limited response,leading to poor prognosis.Telitacicept,a biologic agent and fusion protein targeting B cell activating factor(BAFF)and a proliferation inducing ligand(APRIL),offers a novel therapeutic strategy for refractory rheumatism and autoimmune diseases.Clinical trials have shown promising efficacy and safety.In systemic lupus erythematosus,telitacicept reduces disease activity and facilitates glucocorticoid sparing,with favorable outcomes also observed in pediatric patients.In Sjögren's syndrome,telitacicept achieves sustained improvement in clinical symptoms and disease activity.In rheumatoid arthritis,telitacicept improves the response rates for the American College of Rheumatology 20%improvement criteria(ACR20)and for the American College of Rheumatology 50%improvement criteria(ACR50)while significantly reducing glucocorticoid requirements.In IgA vasculitis,studies focused on patients with renal involvement,and showed efficacy in reducing proteinuria in both adults and children.In myasthenia gravis,telitacicept reduces disease severity and improves quality of life.Additionally,telitacicept has shown preliminary therapeutic potential in IgG4-related disease and granulomatosis with polyangiitis,warranting further investigation.Existing clinical data indicate a favorable overall safety profile for telitacicept.However,attention should be paid to long-term risks of infection,decreased immunoglobulin levels,potential resistance mechanisms,and its efficacy and safety in special populations.This review summarizes recent research progress on the use of telitacicept in rheumatism and autoimmune diseases,aiming to provide a reference for its clinical application.
