Baseline data of patients with good or poor long-term renal outcome*
| Good outcome (n=83) | Poor outcome (n=21) | p Value† | |
|---|---|---|---|
| ECLAM (median, range) | 7 (2–10) | 7 (4–10) | 0.85 |
| SLEDAI (median, range) | 19 (4–38) | 15 (9–24) | 0.09 |
| Systolic blood pressure (mm Hg) (mean±SD) | 128±17 | 131±17 | 0.61 |
| Diastolic blood pressure (mmHg) (mean±SD) | 78±11 | 79±8 | 0.81 |
| Serum creatinine (mg/dL) (mean±SD) | 1.04±0.41 | 0.80±0.35 | 0.07 |
| Proteinuria (g/d) (mean±SD) | 3.1±2.5 | 3.4±2.9 | 0.71 |
| Serum albumin (g/dL) (mean±SD) | 3.0±0.7 | 2.8±0.7 | 0.11 |
| Serum complement C3 (mg/dL) (mean±SD) | 57±55 | 52±33 | 0.69 |
| uRBCs ≥5/hpf (%) | 87 | 82 | 0.70 |
| WHO class III/IV/Vc/Vd (%) | 29/60/4/7 | 43/52/0/5 | 0.55 |
*Long-term renal outcome was defined based on last serum creatinine (≤120% of baseline value for good responders and >120% for poor responders).
†By Mann-Whitney U-test for ECLAM and SLEDAI, Fisher's exact test for RBCs, χ2 test for WHO class and unpaired t-test for the other values.
ECLAM, European Consensus Lupus Activity Measurement; hpf, high power field; SLEDAI, Systemic Lupus Erythematosus Disease Activity Index; uRBCs, urinary red blood cells.
