Systemic lupus erythematosus (SLE) is a complex autoimmune disease affecting various organs and characterized by profound immune disturbances. Monoclonal antibodies such as anifrolumab, targeting type I interferon, and belimumab, targeting a cytokine that activates B-cells and plasmocytes, have shown efficacy in SLE. Voclosporine, a novel calcineurin inhibitor, improves renal outcomes when combined with standard immunosuppression in lupus nephritis. Other approaches like obinutuzumab and CAR-T cells offer hope for refractory patients. These advances diversify SLE management, though their long-term efficacy remains to be established. It is crucial to emphasize basic measures in patients with SLE, including smoking cessation, sun protection, and early use of hydroxychloroquine.
