Abstract:

Objective To investigate the efficacy and safety of belimumab in the treatment of new-onset systemic lupus erythematosus (SLE). Methods Sixty patients with newly diagnosed SLE were selected and divided into 2 groups, with 30 patients in each group. One group received standard treatment, and the other group received beliumab combined with standard treatment. The indexes of the two groups before and after 10-month treatment were recorded,including white blood cell (WBC), platelet (PLT), hemoglobin (Hb), complement C3 (C3), complement C4 (C4), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), serum white sphere ratio (AGR), immunoglobulin G (IgG), double-stranded DNA (ds-DNA), antinuclear antibody titer (ANA), 24 h urine protein quantification, prednisone acetate dosage before and after treatment and disease activity index (SLEDAI-2000). Adverse events were also recorded. Results After treatment, blood WBC, PLT, Hb, C3, C4 and AGR were higher than those before treatment in the two groups, and WBC, C3 and AGR were significantly higher in the belliumab group than those in the standard treatment group (P<0.05). IgG, ESR and ds-DNA were all decreased after treatment in the two groups of patients, and those of belliumab group were lower than the other groups after treatment (P<0.05). After treatment, doses of SLEDAI-2000 and prednisone acetate decreased in the 2 groups compared with before treatment, and those of belliumab group were lower than the standard treatment group after treatment (P<0.05). After treatment, 24 h urinary protein quantity of renal affected patients was lower in 2 groups than before treatment, and that of the belliumab group was lower than that of the standard treatment group (P<0.05). After treatment, the total effective rate was higher in the belliumab group than that of the standard treatment group (P<0.05). There was no significant difference in the incidence of adverse reactions during treatment between the two groups (P =1.000). Conclusion Beliumab can assist in reducing glucocorticoid dosage to help control disease activity without increasing adverse events, and it is recommended for the treatment of lupus patients with initial mild to moderate disease activity.
