Levels of α-defensin in the sera of 52 systemic lupus erythematosus (SLE) patients and 20 age- and sex-matched healthy controls. Serum α-defensin levels were determined by enzyme-linked immunosorbent assay (ELISA), as described in the Materials and methods section. The means ± SD for SLE patients and healthy controls were 18·5 ± 13·36 and 0·12 ± 0·07 ng/μl, respectively. The mean α-defensin level for 20 healthy controls + 2 standard deviations (0·26 ng/μl) was defined as the upper normal limit.
