Comparison of plasma biomarkers in the AD and in the normal control group
| AD | Control | t or U test | |
|---|---|---|---|
| IL-6, pg/ml | 2.343 ± 1.379 (n = 38) | 1.622± 0.806 (n = 39) | p = 0.0071a* |
| IL-18, pg/ml | 250.6 ± 141.8 (n = 38) | 249.6± 132.0 (n = 39) | p = 0.6782 |
| Fractalkine, pg/ml | 618.2 ± 209.5 (n = 39) | 580.6± 114.3 (n = 36) | p = 0.3339a |
| TRAIL, pg/ml | 121.8 ±40.42 (n = 41) | 143.0± 34.56 (n = 40) | p = 0.0132* |
Data are presented as mean ± standard deviation. Plasma levels of IL-6 were elevated in the AD group compared to the normal control group. No group difference in plasma levels of IL-18 or fractalkine was noted. Decreased levels of plasma TRAIL were found in the AD group.
