The purpose of this study was to explore the clinical and immunological efficacy of belimumab plus low dose IL-2 in systemic lupus erythematosus.


Given that belimumab and low dose interleukin-2 (IL-2) have been widespreadly applied in the treatment of systemic lupus erythematosus (SLE), this study designed a randomised, single center, prospective study to investigate the effects and safety of combined utilization of belimumab and low dose IL-2. SLE patients were allocated in each group randomly (n=10) and regularly administered belimumab (10mg/kg) with or without IL-2 (1 million IU). Then, we evaluated the improvement of clinical and laboratory indexes and monitored the changes of immune cell subsets and cytokines.
