Plasma expression of IL-33 and sST2 in AA and controls. Plasma concentrations of IL-33 in AA patients with active disease (22.7 ± 13.7 pg/ml) were found to be significantly lower than those of healthy controls (45.8 ± 24.6 pg/ml, P < 0.01) and AA patients in remission (36.8 ± 29.5 pg/ml, P < 0.01) (a). Plasma sST2 levels of AA patients with active disease (1370.1 ± 530.3 pg/ml) were significantly higher compared with healthy controls (903.7 ± 329.3 pg/ml, P < 0.01) and patients in remission (1331.8 ± 454.3 pg/ml, P < 0.01) (b)
