Health-related quality of life, remission and low lupus disease activity state in patients with systemic lupus erythematosus.

Objectives: To measure the association between SLE remission and scores of patients-reported outcome (PRO) measures.

Methods: We performed a prospective cohort study of SLE patients with a 2-year follow-up, using Lupus Patient-Reported Outcome (LupusPRO), Lupus Quality of Life (LupusQoL), Systemic Lupus Erythematosus Quality of Life (SLEQOL) and 36-item Short Form (SF-36) questionnaires. Remission was defined as remission off treatment (ROFT) and remission on treatment (RONT) according to the definitions of remission in SLE consensus.
