Systemic lupus erythematosus (SLE) is a highly specific autoimmune disease that involves multiple systems due to abnormal immune activation. It is a classical diffuse connective tissue disease with autoimmune inflammation as its prominent manifestation. B cells are the core of systemic lupus erythematosus (SLE) pathogenesis. B Lymphocyte Stimulator (BLyS, also called BAFF) and A Proliferation-Inducing Ligand (APRIL) are signals for B cell maturation. B Lymphocyte Stimulator (BLyS) participates in promoting the development and maturation of B cells, while A Proliferation-Inducing Ligand (APRIL) participates in promoting the activation of mature B cells and the secretion of antibodies by plasma cells. Telitacicept is composed of the extracellular specific soluble portion of Transmembrane Activator and Calcium-modulating Cyclophilin Ligand (CAML) Interactor (TACI) and the Fragment crystallizable (Fc) segment of human Immunoglobulin G1 (IgG1). It is the only globally approved dual-target biological agent for the treatment of systemic lupus erythematosus (SLE) , blocking B Lymphocyte Stimulator (BLyS) and A Proliferation-Inducing Ligand (APRIL), hindering the development and activation of B cells, and the production of antibodies, comprehensively inhibiting the maturation, proliferation, and differentiation of B cells at different stages. In this study, the investigators will explore the adherence and influencing factors of telitacicept in systemic lupus erythematosus (SLE) patients, its effectiveness, and safety, providing a stronger basis for clinical management of systemic lupus erythematosus (SLE) patients.

RECRUITINGSafety of Estrogens in Lupus National Assessment-Systemic Lupus Erythematosus Disease Activity Index （SELENA-SLEDAI）
Safety of Estrogens in Lupus National Assessment-Systemic Lupus Erythematosus Disease Activity Index （SELENA-SLEDAI） is a cumulative and weighted index used to assess disease activity across 24 different disease descriptors in patients with SLE. It is scored by a table named "SELENA-SLEDAI (Systemic Lupus Erythematosus Disease Activity Index) INSTRUMENT SCORE" . The minimum and maximum values are 0 points and 105 points separately, but very few patients score higher than 45 points. Higher scores indicate higher disease activity.
Time frame: Baseline and Month1, Month 2, Month 3, Month 6, Month 9, Month 12 after injecting Telitacecipt
Physician's Global Assessment
Physician's global assessment for patients with Systemic Lupus Erythematosus (SLE) is a subjective assessment tool used by a same physicians to evaluate the overall disease activity based on clinical observations and patient reports(the patient's symptoms, physical examination findings, laboratory results, and any other relevant clinical information). The physician's global assessment (PGA) scale typically ranges from 0 to 3, with 0 representing no disease activity and 3 representing severe disease activity. Some variations of the scale may include intermediate markers, such as 1 and 2, to indicate varying degrees of disease activity.
Time frame: Baseline and Month1, Month 2, Month 3, Month 6, Month 9, Month 12 after injecting Telitacecipt
Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F)
Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F) is a questionnaire-based tool (FACIT-F, Vision 4) used to measure fatigue in patients. It consists of multiple items, each focusing on a different aspect of fatigue. The items are typically rated on a scale from 0 to 4, with 0 representing "not at all" and 4 representing "very much". Example items include: "I feel tired" or "I'm too tired to working". Higher scores indicate less fatigue.
