Elevated serum decoy receptor 3 (DcR3) concentrations (ng/ml) in systemic lupus erythematosus (SLE) patients. (a) Samples from 152 SLE patients, 40 health controls and 122 rheumatoid arthritis (RA) patients were collected, and the serum DcR3 levels were detected with a DcR3 enzyme-linked immunosorbent assay kit. The horizontal lines give the mean DcR3 value. Statistical analysis by the Mann–Whitney rank sum test revealed significantly elevated serum DcR3 in SLE patients when compared with healthy controls (P < 0·001) and RA patients (P < 0·005). (b) Serum DcR3 concentrations in SLE patients with active [SLE disease activity index (SLEDAI) ≥ 10; n = 77] and inactive disease (SLEDAI < 10; n = 75). Statistical analysis with the Mann–Whitney rank sum test revealed a significant difference between the two groups (P < 0·005).
