Background: Hydroxychloroquine (HCQ) is a widely prescribed medication to patients with systemic lupus erythematosus (SLE), with potential anti-inflammatory effects. This study was performed to investigate the efficacy of HCQ therapy by serial assessment of disease activity and serum levels of proinflammatory cytokines in SLE patients.
Methods: In this prospective cohort study, 41 newly diagnosed SLE patients receiving 400 mg HCQ per day were included.
