Objectives To analyze activity and response to therapies in a large multicenter sample of patients with systemic lupus erythematosus (SLE).

Methods Study design: national, multicenter, cross-sectional. Patients: SLE patients according to ACR criteria. Data collected: demographics, comorbidities, disease characteristics: activity (SELENA-SLEDAI), damage, severity, hospitalizations, mortality and treatments. Data about activity were collected in a cumulative way (at some stage) and at the time of the last evaluation. SLE was considered refractory if at least one of these criteria were present at some stage of the disease: ineffectiveness of cyclophosphamide, ineffectiveness of at least 2 non-biological immunosuppressants other than cyclophosphamide, use of rituximab or splenectomy. A multivariate analysis of the factors associated with refractory disease was performed.

Results 3,658 patients (90% female; median age[IR]: 46.8 years[20.8]; 93% Caucasians; median SLE duration[IR]:124 months[141]) were included in 45 centers. At the time of their last evaluation, 14.7% of the patients had moderate-severe SLE (SELENA-SLEDAI score ≥6). 1,954 (53.4%) patients were hospitalized due to activity at least once over the course of the disease. Activity was the main cause of death (26%) among the deceased patients. At some stage, 84.6% of the patients received corticosteroids. Due to either toxicity or ineffectiveness, cyclophosphamide was withdrawn in 21.5% of the cases, mycophenolate mofetil in 24.9%, azathioprine in 40.2% and methotrexate in 46.8%. 898 (24.5%) patients had refractory SLE at some stage. Renal, neuropsychiatric, vasculitic, hematological and musculoskeletal involvement, a younger age at diagnosis and male sex are associated with refractory disease.

Conclusions A significant percentage of patients have moderately-to-severely active SLE at some stage. Disease activity has a big impact in terms of need for treatments, cause of hospitalization and death. The effectiveness of the standard therapies for reducing disease activity is clearly insufficient.
