Hydroxychloroquine Associated With Lower Glomerular Filtration Rate Decline in Lupus Nephritis

open access: yesArthritis Care &Research, EarlyView.
Objective Hydroxychloroquine (HCQ) protects kidney function in lupus nephritis (LN) by preventing flares, yet some cohort studies show no significant benefit in kidney function with HCQ. Clarifying these conflicting findings by showing early and long‐term benefits of HCQ on kidney function preservation is critical.
