Early endpoints predicting long-term outcome in lupus nephritis (LN), which could be used as outcome measures in clinical trials, are still debated. Recently, a multicentric study, using an extended international database of prospectively followed LN patients, succeeded in computing equations (hazard index; HI) predicting adverse kidney outcomes, in casu chronic kidney disease (CKD), severe kidney injury (SKI) and renal replacement therapy (RRT). These HI were validated in a replicate cohort. The HI for CKD, SKI and RRT (calculated with data measured at one year) were significantly higher in groups with long-term poor renal outcomes after a follow-up (FU) of ≥ 4 years
