Lupus & antiphospholipid syndrome

Lupus nephritis at systemic lupus erythematosus onset and kidney outcomes in a Latin American biopsy-proven cohort

LupusPublished Retrospective cohort study

Authors' conclusion

LNSO was not independently associated with kidney or survival outcomes.

Study context

Population
Adults (≥18 years) with biopsy-proven lupus nephritis (LN), tertiary centers in Colombia (2011–2024)median follow-up 5.3 years
Participants
428 adults
Exposure
LN at systemic lupus erythematosus (SLE) onset vs LN occurring later
  • LNSOn = 281
  • non-LNSOn = 147reference
Outcome
ESKD: sustained eGFR <15 mL/min/1.73 m² for ≥3 months, chronic dialysis, or kidney transplantation
Methodological detailsmulticentre (tertiary centers), cause-specific Cox and Fine-Gray models, 180-day landmark analysis

Main finding

As reported in the abstract

ESKD
LNSO vs non-LNSOEstimate (95% CI)
ESKD
aHR 0.87(0.48–1.60)
Competing-risk model
sHR 0.85(0.19–3.84)
End-stage kidney disease (ESKD) overall
72 patients (16.8%)

Observational data: associations, not effects.

Secondary outcomes

Composite of ESKD, death, or doubling of creatinine

Occurred in 156 patients; not associated with LNSO

Predictors of ESKD

Lower baseline eGFR, higher NIH chronicity index, and higher non-renal damage associated with ESKD

No remission at 6 months (180-day landmark analysis)

Strongly predicted adverse outcomes
