Abstract

fetched live from OpenAlex

OBJECTIVES: Lupus nephritis (LN) most commonly develops in the initial years after Systemic Lupus Erythematosus (SLE) onset. We aimed to investigate the impact of the time to LN onset on the clinical presentation and outcomes of LN. METHODS: We included 246 inception cohort patients who developed LN during follow-up. We categorized patients into three groups based on the time to LN onset: group 1 (early, ≤1 year, 160 patients), group 2 (intermediate, >1 to ≤5 years, 42 patients), and group 3 (delayed, >5 years, 44 patients). The outcomes assessed were complete proteinuria recovery (CPR) at one year, the occurrence of an adverse composite outcome (end-stage kidney disease [ESKD], a sustained ≥40 % decline in eGFR, or death), and the development of subsequent LN flares. Cox proportional hazard models were used to study associations with the outcomes. RESULTS: At baseline, the median [IQR] age was 34.3 [26.2, 44.7] years, with a median disease duration of 0.6 [0.2, 2.6] years. Delayed LN patients were older at baseline, had higher SDI, used glucocorticoids and immunosuppressives less frequently, and were less likely to achieve CPR at 1 year. Early LN patients had the lowest risk of developing the adverse composite outcome. In the Cox models, compared to early LN, intermediate LN was associated with an increased risk of developing the adverse composite outcome and showed a trend towards a higher association with subsequent LN flares. CONCLUSIONS: Intermediate LN, occurring between the first and fifth year after SLE onset, is associated with the worst renal outcomes.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
