Treatment of active systemic lupus erythematosus with baricitinib: A meta-analysis of randomized controlled trials

초록

Objective: This study aimed to evaluate the safety and effectiveness of baricitinib in patients with systemic lupus erythematosus (SLE).Methods: We searched MEDLINE, EMBASE, and the Cochrane Controlled Trials Register to find relevant publications. Using data from randomized controlled trials (RCTs), we performed a meta-analysis to investigate the safety and efficacy of baricitinib in patients with active SLE who did not respond well to standard treatments.Results: A total of 1849 individuals (1235 experimental participants and 614 controls) from three RCTs on baricitinib were included. A reduction of >= 4 points from baseline in SLEDAI-2K score in the baricitinib 4 mg group was greater than the placebo group's reduction (odds ratio [OR] = 1.407, 95% confidence interval [CI] 1.123-1.763, p = .003). The baricitinib 4 mg group significantly outperformed the placebo group in terms of SLEDAI-2K remission of arthritis or rash (OR = 1.327, 95% CI = 1.059-1.663, p = .014). Other effectiveness outcomes such as the SRI4 response did not substantially improve in the baricitinib 4 mg group when compared with the placebo group. And there were no significant increase in the efficacy outcomes in the baricitinib 2 mg group than in the placebo group. However, there was a substantially higher incidence of severe adverse events (SAE) and serious infections in the baricitinib 4 mg group (OR = 1.493, 95% CI = 1.002-2.225, p = .049; OR = 2.303, 95% CI = 1.147-4.622, p = .019) compared to the placebo group. There were no differences between the baricitinib 2 mg and placebo groups in any of the safety outcome data.Conclusion: Meta-analysis reveals that baricitinib 4 mg is beneficial for treating active SLE in terms of a reduction of >= 4 points from baseline in SLEDAI-2K score and SLEDAI-2K remission of arthritis or rash. However, the higher frequency of SAEs and serious infections was observed in the group receiving baricitinib 4 mg.
