Differential impact of disease activity and damage on health-related quality of life in patients with systemic lupus erythematosus.

In this cohort of multi-ethnic Asian SLE patients, disease activity is associated with poorer mental, but not physical, HRQoL; whereas disease-related damage is associated with poorer physical, but not mental HRQoL. Our findings suggest a need to differentially approach the impaired HRQoL in SLE patients at different phases of disease; possibly by treating disease activity in patients with impaired mental HRQoL and addressing disease-related damage in patients with impaired physical functioning.
