Adaptation of the Russian version of the activity index of systemic lupus erythematosus EASY-BILAG

Assessment of systemic lupus erythematosus (SLE) activity is important to determine the efficacy of treatment and to decide on further therapy. Russian-language versions of activity indices are needed to meet the needs of Russian-speaking patients and clinicians and to facilitate the use of these tools in clinical practice. An important step in this direction is the adaptation of the EASY-BILAG index, which is used to more accurately assess disease activity and select appropriate therapy in patients with SLE.
