SLE cannot be cured. SLE is an autoimmune disease, and many patients can achieve clinical remission after early detection and regular treatment, but long-term maintenance treatment is required and cannot be completely discontinued, because once the drug is completely discontinued, the possibility of relapse is greater. The specific pathogenesis of SLE is not very clear, but it is common in women and may be related to sex hormones, heredity, infection, physical and chemical factors. At present, the treatment of SLE mainly takes glucocorticoids and immunosuppressants, such as cyclophosphamide, morte-macrolide, tacrolimus, cyclosporine, leflunomide, methotrexate and other combined treatments. During the treatment period, regular review is required, including blood count, sedimentation, C-reactive protein, urine routine, etc.
