Cyclosporine may reduce the risk of symptomatic COVID-19 in patients with systemic lupus erythematosus: a retrospective cohort study

ABSTRACT This study aimed to explore the effect of cyclosporine (CsA) on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in systemic lupus erythematosus (SLE) patients to provide a valuable reference for clinical treatment strategies in the context of the long-term risk of SARS-CoV-2 infection. SLE patients who visited the Rheumatology Outpatient Department of Fujian Medical University Union Hospital between 1 May and 31 October 2022 were included. Data on SARS-CoV-2 infection in patients between 1 November 2022 and 31 July 2023 were obtained by telephone follow-up. Patients were divided into two groups according to whether CsA was used during the observation period: the glucocorticoid or hydroxychloroquine group and the CsA group. To assess the robustness of the results, Data sets 1 and 2 were established to be analyzed independently. Multivariate logistic regression was used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) for symptomatic coronavirus disease (COVID-19). A total of 184 patients were included, among whom 129 were definite symptomatic COVID-19 patients; 29 were presumptive symptomatic COVID-19 patients; and 4 had signs and symptoms of COVID-19, but tested negative for SARS-CoV-2 in a virological test. According to the multivariable-adjusted models, CsA was associated with lower odds of symptomatic COVID-19 (P = 0.042, OR = 0.316, 95% CI: 0.104–0.959 in Data set 1 and P = 0.021, OR = 0.257, 95% CI: 0.081–0.812 in Data set 2). CsA is associated with lower odds of contracting symptomatic COVID-19. The use of CsA may be considered an appropriate therapeutic option for disease management in patients with rheumatic diseases who have severe disease activity and persistent SARS-CoV-2 infection.IMPORTANCEOur study indicated that cyclosporine may reduce the risk of symptomatic COVID-19 in systemic lupus erythematosus patients in spite of its immunosuppressive effects. This study provides a reference for clinical treatment strategies for AIIRD patients in the context of the long-term risk of SARS-CoV-2 infection.
