IL22 and dengue disease: Interestingly, serum concentrations of IL-17A and IL-22 were significantly higher in DHF patients (IL-17A median 103.8 pg/mL, IQR 69.5–153.8; IL-22 median 59.0 pg/mL, IQR 23.4–122.1) than in DF patients (IL-17A median 68.7 pg/mL, IQR 12.6–111.7; IL-22 median 17.6 pg/mL, IQR 0–65.4) (p < 0.05) (Figure 3).
