Abstract

Background: Emerging therapies have the potential to be used in patients with severe refractory systemic lupus erythematosus (srSLE), but no agreed definition of srSLE exists. We evaluated a pilot srSLE definition to assess whether a set of disease activity and treatment thresholds could identify patients with poor outcomes. Methods: Data from a 13-country longitudinal SLE cohort, collected prospectively between 2013 and 2020 were analysed. srSLE was defined if a patient was in high disease activity (SLEDAI-2K ≥ 10) despite combination use of at least glucocorticoids (GC) and immunosuppressants (IS) at both the index and preceding visit. Synchronised to the index srSLE visit, we assessed dis..
