In nasal lavage fluid, the levels of type 2 cytokines (IL-4: 7.82 ± 2.82 vs. 11.69 ± 3.15, p = 0.0394; IL-5: 5.88 ± 6.12 vs. 18.97 ± 12.67, p = 0.0259; IL-13: 8.36 ± 2.68 vs. 16.01 ± 8.22, p = 0.0356) and eotaxin (17.56 ± 13.14 vs. 60.75 ± 37.91, p = 0.0305) were lower in the DKO group than the CRS group (Figure 8B). This evidence concerns the gene IL4 and congenital rubella syndrome.
