Abstract
BACKGROUND: Anti-BLyS treatment with the human belimumab monoclonal antibody was shown to be a safe and effective therapeutic modality in lupus patients with active disease (i.e., without significant neurological/renal involvement) despite standard treatment.
OBJECTIVES: To evaluate the "real-life" safety and efficacy of belimumab added to standard therapy in patents with active lupus in five Israeli medical centers.
METHODS: We conducted a retrospective open-labeled study of 36 lupus patients who received belimumab monthly for at least 1 year in addition to standard treatment. Laboratory tests (C3/C4, anti dsDNA autoantibodies, chemistry, urinalysis and complete blood count) were done every 3-4 months. Adverse events were obtained from patients' medical records. Efficacy assessment by the treating physicians was defined as excellent, good/partial, or no response.
RESULTS: The study group comprised 36 lupus patients (8 males, 28 females) with a mean age of 41.6 } 12.2 years. Belimumab was given for a mean period of 2.3 } 1.7 years (range 1-7). None of the patients discontinued belimumab due to adverse events. Four patients (11.1%) had an infection related to belimumab. Only 5 patients (13.9%) stopped taking belimumab due to lack of efficacy. The response was excellent in 25 patients (69.5%) and good/partial in the other 6 (16.6%). Concomitantly, serological response (reduction of C3/C4 and anti-dsDNA autoantibodies) was also observed. Moreover, following belimumab treatment, there was a significant reduction in the usage of corticosteroids (from 100% to 27.7%) and immunosuppressive agents (from 83.3% to 8.3%).
CONCLUSIONS: Belimumab, in addition to standard therapy, is a safe and effective treatment for active lupus patients.
